The history of Yamaha Motorcycles
"I want to carry out trial manufacture of motorcycle engines." It was from these words spoken by Genichi Kawakami (Yamaha Motor's first president) in 1953, that today's Yamaha Motor Company was born.
"If you're going to do something, be the best."
Genichi Kawakami
Genichi Kawakami was the first son of Kaichi Kawakami, the third-generation president of Nippon Gakki (musical instruments and electronics; presently Yamaha Corporation). Genichi studied and graduated from Takachiho Higher Commercial School in March of 1934. In July of 1937, he was the second Kawakami to join the Nippon Gakki Company.
He quickly rose to positions of manager of the company's Tenryu Factory Company (musical instruments) and then Senior General Manager, before assuming the position of fourth-generation President in 1950 at the young age of 38.
In 1953, Genichi was looking for a way to make use of idle machining equipment that had previously been used to make aircraft propellers. Looking back on the founding of Yamaha Motor Company, Genichi had this to say. "While the company was performing well and had some financial leeway, I felt the need to look for our next area of business. So, I did some research." He explored producing many products, including sewing machines, auto parts, scooters, three-wheeled utility vehicles, and…motorcycles. Market and competitive factors led him to focus on the motorcycle market. Genichi actually visited the United States many times during this period.
When asked about this decision, he said, "I had my research division chief and other managers visit leading motorcycle factories around the country. They came back and told me there was still plenty of opportunity, even if we were entering the market late. I didn't want to be completely unprepared in this unfamiliar business so we toured to German factories before setting out to build our first 125cc bike. I joined in this tour around Europe during which my chief engineers learned how to build motorbikes. We did as much research as possible to insure that we could build a bike as good as any out there. Once we had that confidence, we started going."
The first Yamaha motorcycle... the YA-1.
"If you are going to make it, make it the very best there is." With these words as their motto, the development team poured all their energies into building the first prototype, and ten months later in August of 1954 the first model was complete. It was the Yamaha YA-1. The bike was powered by an air-cooled, 2-stroke, single cylinder 125cc engine. Once finished, it was put through an unprecedented 10,000 km endurance test to ensure that its quality was top-class. This was destined to be the first crystallization of what has now become a long tradition of Yamaha creativity and an inexhaustible spirit of challenge.
Then, in January of 1955 the Hamakita Factory of Nippon Gakki was built and production began on the YA-1. With confidence in the new direction that Genichi was taking, Yamaha Motor Co., Ltd. was founded on July 1, 1955. Staffed by 274 enthusiastic employees, the new motorcycle manufacturer built about 200 units per month.
That same year, Yamaha entered its new YA-1 in the two biggest race events in Japan. They were the 3rd Mt. Fuji Ascent Race and the 1st Asama Highlands Race. In these debut races Yamaha won the 125cc class. And, the following year the YA-1 won again in both the Light and Ultra-light classes of the Asama Highlands Race.
By 1956, a second model was ready for production. This was the YC1, a 175cc single cylinder two-stroke. In 1957 Yamaha began production of its first 250cc, two-stroke twin, the YD1.
The first Yamaha to compete in America (1957).
Based on Genichi's firm belief that a product isn't a product until it can hold it's own around the world, in 1958 Yamaha became the first Japanese maker to venture into the international race arena. The result was an impressive 6th place in the Catalina Grand Prix race in the USA. News of this achievement won immediate recognition for the high level of Yamaha technology not only in Japan but among American race fans, as well. This was only the start, however.
Yamaha took quick action using the momentum gained in the USA and began marketing their motorcycles through an independent distributor in California. In 1958, Cooper Motors began selling the YD-1 250 and the MF-1 (50cc, two-stroke, single cylinder, step through street bike). Then in 1960, Yamaha International Corporation began selling motorcycles in the USA through dealers.
With the overseas experiences under his belt, in 1960, Genichi then turned his attention to the Marine industry and the production of the first Yamaha boats and outboard motors. This was the beginning of an aggressive expansion into new fields utilizing the new engines and FRP (fiberglass reinforced plastic) technologies. The first watercraft model was the CAT-21, followed by the RUN-13 and the P-7 123cc outboard motor.
In 1963, Yamaha demonstrated its focus on cutting-edge, technological innovations by developing the Autolube System. This landmark solution was a separate oil injection system for two-stroke models, eliminating the inconvenience of pre-mixing fuel and oil.
Yamaha was building a strong reputation as a superior manufacturer which was reflected in its first project carried out in the new Iwata, Japan Plant, built in 1966. (The YMC headquarters was moved to Iwata in 1972.) Toyota and Yamaha teamed up to produce the highly regarded Toyota 2000 GT sports car. This very limited edition vehicle, still admired for its performance and craftsmanship, created a sensation among enthusiast in Japan and abroad.
Genichi said, "I believe that the most important thing when building a product is to always keep in mind the standpoint of the people who will use it." An example of the commitment to "walking in the customers' shoes" was the move in 1966 by Yamaha to continue its expansion. Overseas motorcycle manufacturing was established in Thailand and Mexico. In 1968, the globalization continued with Brazil and the Netherlands. With manufacturing bases, distributors and R&D operations in a market, Yamaha could be involved in grassroots efforts to build products that truly met the needs of each market by respecting and valuing the distinct national sensibilities and customs of each country. Yamaha continues that tradition, today.
By the late 1960s, Yamaha had quality products that had proven themselves in the global marketplace based on superior performance and innovation. Distribution and product diversity were on the right track. But Genichi knew that beyond quality, success would demand more. He had this view on the power of original ideas. "In the future, a company's future will hinge on ideas over and above quality. Products that have no character, nothing unique about them, will not sell no matter how well made or affordable…and that would spell doom for any company."
He also knew that forward vision, walking hand in hand with original ideas, would create an opportunity for the company and its customers that could mean years of happiness and memorable experiences. Genichi said, "In the business world today, so many people are obsessed with figures. They become fixated on the numbers of the minute and without them are too afraid to do any real work. But in fact, every situation is in flux from moment to moment, developing with a natural flow. Unless one reads that flow, it is impossible to start out in a new field of business."
A real-world illustration of this belief is the Yamaha DT-1. The world's first true off-road motorcycle debuted in 1968 to create an entirely new genre we know today as trail bikes. The DT-1 made a huge impact on motorcycling in the USA because it was truly dirt worthy. Yamaha definitely "read the flow" when it produced
"Make every challenge an opportunity."
Genichi Kawakami
the 250cc, single cylinder, 2-stroke, Enduro that put Yamaha On/Off-Road motorcycles on the map in the USA. The DT-1 exemplified the power of original ideas, forward vision, and quick action coupled with keeping in mind the customers' desires.
In years to come Yamaha continued to grow (and continues to this day). Diversity increased with the addition of products including snowmobiles, race kart engines, generators, scooters, ATVs, personal watercraft and more.
Genichi Kawakami set the stage for Yamaha Motor Company's success with his vision and philosophies. Total honesty towards the customer and making products that hold their own enables the company that serves people in thirty-three countries, to provide an improved lifestyle through exceptional quality, high performance products.
Yamaha Motor Corporation, USA Cypress, California
Genichi Kawakami's history with Yamaha was long and rich. He saw the new corporate headquarters in Cypress, California and the 25th Anniversary of Yamaha become a reality in 1980. He also watched bike #20 million roll off the assembly line in 1982. Genichi passed away on May 25, 2002 yet his vision lives on through the people and products of Yamaha, throughout the world.

Abstract
Space medicine research has drawn immense attention toward provision of efficient life support systems during long-term missions into space. However, in extended missions, a wide range of diseases may affect astronauts. In space medicine research, the gastrointestinal microbiome and its role in maintaining astronauts' health has received little attention.
We would like to draw researchers' attention to the significant role of microbiota. Because of the high number of microorganisms in the human body, man has been called a 'supra-organism' and gastrointestinal flora has been referred to as 'a virtual organ of the human body'.
In space, the lifestyle, sterility of spaceship and environmental stresses can result in alterations in intestinal microbiota, which can lead to an impaired immunity and predispose astronauts to illness. This concern is heightened by increase in virulence of pathogens in microgravity. Thus, design of a personal probiotic kit is recommended to improve the health status of astronauts.
Introduction
Living in space has been a great desire for mankind, leading to the development of space stations for long-duration manned space missions. The design of a life support system is needed to maintain the minimum life requirements for humans in space by conserving a stable body temperature, a standard pressure on the body and by managing waste products.
So far, the majority of research in this area has been devoted to the human primary requirements such as air, water and food. Furthermore, a life support system deals with astronauts' healthcare. Although health status of the astronauts such as immunological and physiological problems has been investigated, less attention has been paid to the intestinal microbiome and its significant role in the astronaut's health.
Immunological and physiological health problems could occur when considering the identified increase in the virulence and antibiotic resistance of some infectious bacteria exposed to microgravity, along with possible weakening of the immune system during space flight. Compensating for these alterations may not only enhance the health and immunity status of astronauts, but might have possible effects on enhancing the duration of space journeys.
For many years, the importance of intestinal flora in human health and disease has been known to man. Researchers have suggested a possible association between the changes in the balance of gut flora and several diseases. At the end of the Human Genome Project, the aggregation of flora genes within the human genome was named the 'human metagenome, highlighting the crucial role of the microbiome in the maintenance of health.
This perspective highlights the crucial role of the microbiome in the health and/or disease status in astronauts. Considering astronauts' special health and nutrition needs in orbit, it could be advantageous to develop probiotics for each crew member. These healthy bacteria could then be consumed during long-duration missions to replenish the intestinal microbiome.
The Human Intestine & the Microbiome
Today 'gut health' is a term increasingly used in the medical literature to describe effective digestion and absorption, the absence of gastrointestinal lesions, presence of normal intestinal microflora and proper immune function. However, from a scientific point of view, it is still extremely unclear what gut health is or how it can be defined and/or measured.
The interactions between the gastrointestinal barrier and the microbiome appear to be a complex mechanism that assists in maintaining gut health. The gastrointestinal tract contributes to digestion and absorption of nutrients, minerals and fluids, osmoregulation, endocrine regulation and host metabolism, mucosal and systemic tolerance, immunoenhancement, defense against potential pathogens and harmful substances, signaling from the periphery to the brain, and detoxification of toxic molecules originating from the environment or the host.
Recognition of the importance of gastrointestinal health and microflora can be an important asset to astronauts' health.
Across the large surface of the digestive tract, healthy and pathogenic bacteria compete for dominance. With such a huge exposure area, the immune system has a hard task of hindering pathogens from entering the blood and lymph. The presence of a balance between beneficial and potentially harmful bacteria is considered normal and contributes to a dynamic and healthy human gut.
One way to maintain this homeostasis is to introduce helpful bacteria or probiotics. After the first suggestion of the health benefits of probiotics in the early 20th century by Nobel Laureate Metchnikoff, many bacterial strains have been clinically tested as potential probiotics. Probiotics are thought to play a health-promoting role by improving intestinal microbial infections.
The surface area, apparent balance of microflora and health impact of the human gut reminds us that this complex organ must not be forgotten as one factor in long-duration spaceflight health.
Stress & Gut Microbiome
The Human Genome Project revealed that the human body is the habitat of microbial symbionts ten-times more in number than Homo sapiens cells. The recognition of the complex interactional environment between the human and our symbiotic microflora led researchers to name this the 'human microbiome'.
In the human gut, the microbiome directly influences biochemical, physiological and immunological pathways and is the first line of resistance to various diseases.
Traveling can act as an environmental stress causing changes in the microbiome composition or its gene expression. This may lead to the transient (as in travelers' diarrhea) or permanent dominance of pathogenic gut bacteria. Recently, it was shown that exposure to a social stressor altered the composition of the intestinal microbiome, indicating stressor-induced immunomodulation.
It was demonstrated that stressor exposure changes the stability of the microflora and leads to bacterial translocation. Circulating levels of IL-6 and MCP-1 increased with stressor exposure and these increases were significantly and positively correlated to changes in three bacterial genera (i.e., Coprococcus, Pseudobutyrivibrio and Dorea) in the cecum.
This suggested that the microbiome somehow contributed to stressor-induced immunoenhancement. To test the theory, in follow-up experiments, mice were treated with an antibiotic cocktail to determine whether reducing microflora would annul this stressor-induced increase in circulating cytokines.
In the antibiotic-treated mice, exposure to the same stressor failed to increase IL-6 and MCP-1 confirming that intestinal microflora were necessary for the observed increase in circulating cytokines.
Microgravity Stress Alters Bacterial Virulence
Studies have shown an increase in the virulence, changes in growth modulation and alterations in response to antibiotics in certain bacteria both in space and simulated microgravity. Significant technological and logistical hurdles have hindered thorough genotypic and phenotypic analyses of bacterial response to actual space environment.
In this line, Wilson et al. cultured Salmonella enterica Typhimurium aboard space shuttle mission STS-115 with identical cultures as ground controls. Global microarray and proteomic analyses were carried out and 167 differentially expressed transcripts and 73 proteins were identified among which conserved RNA-binding protein Hfq was suggested as a likely global regulator involved in the response to spaceflight.
Similar results were obtained with ground-based microgravity culture model. Furthermore, spaceflight-grown S. enterica Typhimurium had enhanced virulence in murine models and exhibited extracellular matrix accumulation consistent with a biofilm. Typhimurium grown in spaceflight analog exhibited increased virulence, increased resistance to environmental stresses (acid, osmotic and thermal stress), increased survival in macrophages and global changes in gene expression.
Low-shear modeled microgravity rendered adherent–invasive Escherichia coli more adherent to a mammalian gastrointestinal epithelial-like cell line, Caco-2. Simulated microgravity conditions markedly increased production of the heat-labile enterotoxin from enterotoxigenic E. coli. Upon a 12-day exposure to low-shear modeled microgravity, Candida albicans exhibited increased filamentation, formation of biofilm communities, phenotypic switching and more resistance to the antifungal agent amphotericin B.
Only one virulence gene was found among 163 differentially expressed genes in simulated microgravity grown S. Typhimurium and actually, most virulence genes were expressed at a lower level (including genes involved in lipopolysaccharide production). Furthermore, sigma factor (a transcription factor responsible for a general stress response) was not thought to be a cause, since a decreased level of its gene expression was observed in simulated microgravity.
The mechanism of enhanced virulence of S. Typhimurium grown in actual spaceflight and rotating wall vessel culture conditions does not involve an increased expression of traditional genes that regulate the virulence of this bacterium under normal gravity conditions; however, Hfq pathway is required for full virulence in S. Typhimurium.
Biofilm formation is part of the normal growth cycle of most bacteria and this film is linked to chronic diseases that are difficult to treat such as endocarditis, cystitis and bacterial otitis media. Bacterial biofilm creates superior resistance to oxidative, osmolarity, pH and antibiotic stresses.
Theoretically, bacterial biofilm production, which enhances bacterial survival by resistance to the immune system and antimicrobial agents, may increase the risk and/or severity of infection in long-term space missions. Diminished gravity has been shown to stimulate bacterial biofilm formation both in E. coli and Pseudomonas aeruginosa. In a study by Crabbe et al. in 2008, rotating wall vessel technology was exploited to study the effect of microgravity on growth behavior of P. aeruginosa PAO1.
Rotating wall vessel cultivation resulted in a self-aggregating phenotype, which subsequently led to formation of biofilms. In a second study in 2010, the same researchers employed microarrays to investigate the response of P. aeruginosa PAO1 to low-shear modeled microgravity both in rotating wall vessel and random position machine.
P. aeruginosa demonstrated increased alginate production and upregulation of AlgU-controlled transcripts (including those coding for stress-related proteins) in modeled microgravity. Results of the study also implicated the involvement of Hfq in response of P. aeruginosa to simulated microgravity. Involvement of Hfq in response of P. aeruginosa to actual spaceflight was later confirmed in another study.
In addition, there is concern that antibiotic-resistance increases during short-term spaceflight. The MIC of both colistin and kanamycin increased significantly in E. coli grown aboard the flight module compared with the MIC on the ground. A similar increase in the MIC of oxacillin, erythromycin and chloramphenicol was reported in Staphylococcus aureus. This has led to concerns that the efficacy of antibiotics may be diminished during even short orbital missions.
It has been hypothesized that reduction in the natural, terrestrial diversity of the gastrointestinal bacterial microflora in spaceflight may give rise to an increase in the presence of the drug-resistant bacteria. It has also been postulated that the emergence of such resistant clones could be facilitated by the administration of antibiotics either before or during the flight.
Emergence of drug resistance is also facilitated by bacterial mutation which occurs more frequently in long-term spaceflights. Overall, there is the possibility that drug-resistant bacteria could colonize all crew members on a mission, giving rise to a difficult-to-treat healthcare problem.
Spaceflight & the Microbiome
In an attempt to protect astronauts from exposure to novel pathogens preflight, several guidelines are carried out. Prelaunch, crew members are limited both in travel and visitors to limit pathogen exposure. Therefore, crew members tend to launch with normal gut microflora and with a reduced risk of gut infection.
Items flown to the International Space Station (ISS) are cleaned before loading to limit introducing bacteria to the environment. Once in orbit, all areas in the ISS have ultra-high-efficiency bacterial filters in the air supply ducts to reduce the levels of bacteria and fungi. Finally, cleaning of the surfaces of the modules is a regular 'housekeeping' chore to limit bacterial and fungal growth.
Still, microorganisms exist on the ISS. No matter how much cleaning is done, microorganisms are continuously shed from skin, mucous membranes, gastrointestinal and respiratory tracts or can be released by sneezing, coughing and talking. Specimens were obtained for mycological examination from the skin, throat, urine and feces of the six astronauts who conducted the Apollo 14 and Apollo 15 lunar exploration missions both before and after flight.
Analysis of preflight data demonstrated that the process of severely restricting opportunities for colonization for 3 weeks before flight resulted in a 50% reduction in the number of isolated species. Postflight data indicated that exposure to the spaceflight environment for up to 2 weeks resulted in an even greater reduction with a relative increase in the potential pathogen C. albicans.
The compositions of intestinal, oral and nasal flora have been shown to change even during short spaceflights. In one study, a reduction in the number of nonpathogenic bacteria and an increase in the number of opportunistic pathogens has been reported in the nasal flora of cosmonauts. A significant reduction in the number of bacterial species of the intestine has been seen after 2 weeks of spaceflight.
These observations were similar to changes seen in ground volunteers who were kept in isolation, in which volunteers were fed only sterilized, dehydrated foods. A significant decrease in the number of bifidobacteria, lactobacilli and other bacteria was seen. In a Russian experiment, a decrease in lactobacilli (and replacement with pathogens) were seen in mouth and throat cavities in all mission members in in-flight period.
Spaceflights and even the preparation phase before take-off can exert dysbiosis in the human microflora which results in reduction of the defense group of microorganisms (bifidobacteria and lactobacilli) and appearance of opportunistic pathogens such as E. coli, enterobacteria and clostridia. Subsequently, this procedure can lead to accumulation of the potentially pathogenic species and their long-term persistence.
Colonization resistance is one of the factors that needs to be taken into account to stabilize the microflora of the cosmonauts during space flights. Indigenous microflora are vital for preservation of microecological homeostasis. It has been hypothesized that a regular intake of probiotic foods might be helpful in correcting this change.
Human microflora functions as a barrier against antigens from microorganisms and food. Alterations in the microbiome composition have been reported in inflammatory bowel disease, inflammatory conditions, ulcerative colitis and more. Healthy immunophysiologic regulation in the gut has been hypothesized to depend on the establishment of indigenous microflora that create specific immune responses at the gut and system levels.
Furthermore, gut microflora has a role in induction and maintenance of oral tolerance in experimental animal models. Changes in the diversity and number of gut microflora have been linked to a deficient immune system as well as immunological dysregulation which is associated with many human noninfectious diseases such as autoimmunity, allergy and cancer.
Reinforcing this concept of health symbiosis, studies of germ-free animal showed wide-ranging defects in the development and maturation of gut-associated lymphoid tissues. Another way of viewing this health interaction comes from the data that ten Salmonella bacteria have been shown to induce infection in germ-free mice, while 109 bacteria are needed to induce infection in a conventional animal possessing intact intestinal microflora.
To maintain astronaut health on orbit, an awareness of the importance of a balanced gut microbiome to maintaining the immune homeostasis and resistance to infections is valuable.
Previous studies have shown that important immune parameters are decreased during spaceflight. Reductions in the number and proportion of lymphocytes and their cytokine production, depression of dendritic cells function and T-cell activation, and finally reduction in numbers of monocytes and precursors of macrophages, have been noted.
In one study, stresses associated with spaceflight were shown to alter important functions of neutrophils and monocytes. In another study, the astronauts' monocyte functions showed reductions in their ability to engulf E. coli, elicit an oxidative burst and degranulation. Non-MHC-restricted (CD56) killer cell cytotoxicity tends to decrease after short-term spaceflight.
In the latter study, the authors examined the age, gender (nine men and one woman), flight experience, mission factors and mission role (e.g., pilot, scientist or crew) of the astronauts and found no correlation between these variables and individual non-MHC killer cell function levels.
Therefore, other factors may contribute to the compromised immune system in space. Decreased natural killer cell cytotoxicity in cosmonauts after short- and long-term spaceflights have also been reported. Reductions in absolute numbers of lymphocytes, eosinophils and natural killer cells, reduced lymphocyte mitogenic response, diminished delayed-type hypersensitivity, changes in CD4+:CD8+ ratios and reduced production of IL-2 and IFN-γ have also been reported.
The immune system changes of astronauts as well as environmental stress may have been a factor in known incidents of infectious illness in crew members. During the Apollo 8 preflight period for instance, all crew members suffered viral gastroenteritis. During flight, the effects of mission duration on the neuroimmune responses in astronauts were studied and changes in plasma cortisol, epinephrine, norepinephrine, total IgE levels, number of white blood cells, polymorphonuclear leukocytes and CD4+ T cells were found at different times.
Upper respiratory problems, influenza, viral gastroenteritis, rhinitis, pharyngitis or mild dermatologic problems were among the illnesses that astronauts faced during Apollo spaceflights. Reactivation of varicellas zoster virus, herpes virus and shedding of Epstein–Barr virus was also found in space shuttle crew members.
In astronauts of the Mir station, analyses demonstrated a significant number of episodes of microbial infections, including conjunctivitis, acute respiratory events and dental infections. Future Perspective: Considering Probiotics as a Countermeasure
On Earth, probiotics have been shown to improve both innate and adaptive immune responses. Oral bacteriotherapy with probiotic bacterial strains is believed to improve the intestine's immunologic barrier, particularly through intestinal IgA responses and alleviation of inflammatory reactions. A gut-stabilizing effect seems to occur through a balance between proinflammatory and anti-inflammatory cytokines.
Lactobacillus rhamnosus GG has been shown to inhibit TNF-α-induced IL-8 secretion of human colon adenocarcinoma (HT29) cells and to reduce elevated fecal concentration of TNF-α in patients with atopic dermatitis and cow milk allergy. On the other hand, ingestion of lactobacilli in fermented milk products or as live-attenuated bacteria potentiated the IFN-γ production by peripheral blood mononuclear cells.
Oral administration of lactobacilli increased the systemic and mucosal IgA response to dietary antigens. Oral supplementation with Bifidobacterium bifidum and Bifidobacterium breve enhanced the antibody response to ovalbumin and stimulated the IgA response to cholera toxin in mice. An increase in the humoral immune response including an increase in rotavirus-specific antibody-secreting cells in the IgA class was also detected in children and individuals receiving L. rhamnosus GG.
Isolauri et al. reported that infants receiving a reassortant live oral rotavirus vaccine in conjunction with L. rhamnosus GG had a higher frequency of rotavirus-specific IgM class antibody-secreting cells. An increased incidence of rotavirus-specific IgA antibody class seroconversion compared with placebo subjects was also seen. IgA+ cells and IL-6-producing cells increased in number after 7 days of Lactobacillus casei administration.
In another study, administration of lactic acid bacteria stimulated the gut immune cells to release inflammatory cytokines such as TNF-α, IFN-γ and IL-12, and regulatory cytokines like IL-4 and IL- 10 in a dose- and strain-dependent manner. Several lactobacilli strains have been shown to promote the immunopotentiator capacity of cells of the innate immune system, including macrophages. Examples of probiotics that can modulate the gut immune system are abundant and have been reviewed extensively.
Buckley et al. have suggested that consumption of soy-based fermented products (containing lactic acid bacteria) can prevent the health problems of astronauts associated with long-term space travel. Assessment of soy-based fermented products by in vitro challenge system (using TNF-α) with human intestinal epithelial and macrophage cell lines has demonstrated the ability of the intervention to downregulate production of the proinflammatory cytokine IL-8.
Considering the importance of the human gut in healthy digestion, nutrient absorption and exposure to pathogens across its large surface area, a healthy digestive tract is important to a healthy human. Diet, lifestyle, antibiotic therapy, different kinds of stressful conditions and so on, can exert alterations in an astronaut's gut microbiome in space.
Considering potential immune system alterations from gut microflora changes, antibiotic use in orbit and changes of increased virulence and antibiotic resistance of bacteria in space, physicians who care for astronauts must remember the importance of the intestinal microbiome to their health status. From this perspective, an impaired digestive system might endanger the mission as well as the health of the astronaut. One countermeasure to be considered would be replenishing the astronaut's intestinal microflora by introducing immune-enhancing probiotic bacteria periodically during the mission.
Diet, lifestyle, antibiotic therapy and various environmental stresses, and so on, can exert alterations in an astronaut's gut microbiome in space and impair their immune system.
Although single probiotics have sometimes been shown to promote health, the human microbiome is composed of more than 400 microbial species, most of which remain uncultured and have as yet unknown functions. The Human Microbiome Project will certainly pave the way for us to increase our understanding of these microbial entities.[4] Thus, providing only a single probiotic might not be the answer.
Contrary to numerous previous investigations and clinical trials in which only effects of single or a couple of probiotics have been studied, we think multiprobiotic therapy and/or designing individualized probiotic kits seems a more reasonable option. A series of experiments need to be launched to confirm the efficacy and safety of using probiotics in space.
Safety studies are of equal importance as efficacy studies, since astronauts are immunocompromised (although as discussed above, much of this may return to washing out of microflora in space). These studies can be carried out initially in ground-based space analogs and further followed in actual space (first on animal models and then on humans). The lifestyle of astronauts can be simulated in these studies and after interventions; the composition of microbiota (including opportunistic pathogens) along with immunological markers should be determined.
Both short- and long-term confinement and actual spaceflight studies can be designed. The administration and/or consumption of probiotics is supposed to have immune-enhancing effects, hinder alterations in the human microbiome to a large extent and prevent colonization of potential pathogens. Upon observation of possible benefits, probiotics can be incorporated into astronauts' food or supplied periodically as a probiotic kit.
This line of research can be followed by NASA scientists and other space agencies to enhance the quality of life of astronauts and to contribute to human presence in space.
Surprisingly, this may bring a future where astronauts utilize probiotic bacteria to counteract the potential effect of pathogenic bacteria during spaceflight.

UCSF scientists have successfully treated a patient with severe depression by identifying the personal pattern of brain activity leading to their suffering and using a “brain pacemaker” to restore it to its natural rhythm.
DBS (Deep Brain Stimulation) for mood; can elicit joy with precise placement of electrode; 2mm over, and you might see fear
First patient had TRD, cured with DBS sensing electrode in the amygdala looking for the pattern that signals the onset of her depression, which triggers a second electrode in the ventral striatum — involved in emotion, motivation, and reward, where stimulation consistently eliminated her feelings of depression. None of this is felt or perceived by the patient.
Can detect the precursor to depression before they experience it.
Patient: “Within a few weeks, the suicidal thoughts just disappeared. Then it was just a gradual process where it was like my lens on the world changed.” She smiled for the first time in five years.

The mallard (/ˈmælɑːrd, ˈmælərd/) or wild duck (Anas platyrhynchos) is a dabbling duck that breeds throughout the temperate and subtropical Americas, Eurasia, and North Africa, and has been introduced to New Zealand, Australia, Peru, Brazil, Uruguay, Argentina, Chile, Colombia, the Falkland Islands, and South Africa. This duck belongs to the subfamily Anatinae of the waterfowl family Anatidae. The male birds (drakes) have a glossy green head and are grey on their wings and belly, while the females (hens or ducks) have mainly brown-speckled plumage. Both sexes have an area of white-bordered black or iridescent blue feathers called a speculum on their wings; males especially tend to have blue speculum feathers. The mallard is 50–65 cm (20–26 in) long, of which the body makes up around two-thirds the length. The wingspan is 81–98 cm (32–39 in) and the bill is 4.4 to 6.1 cm (1.7 to 2.4 in) long. It is often slightly heavier than most other dabbling ducks, weighing 0.7–1.6 kg (1.5–3.5 lb). Mallards live in wetlands, eat water plants and small animals, and are social animals preferring to congregate in groups or flocks of varying sizes. This species is the main ancestor of most breeds of domestic ducks.
The female lays eight to 13 creamy white to greenish-buff spotless eggs, on alternate days. Incubation takes 27 to 28 days and fledging takes 50 to 60 days. The ducklings are precocial and fully capable of swimming as soon as they hatch.
The mallard is considered to be a species of least concern by the International Union for Conservation of Nature (IUCN). Unlike many waterfowl, mallards are considered an invasive species in some regions. It is a very adaptable species, being able to live and even thrive in urban areas which may have supported more localised, sensitive species of waterfowl before development. The non-migratory mallard interbreeds with indigenous wild ducks of closely related species through genetic pollution by producing fertile offspring. Complete hybridisation of various species of wild duck gene pools could result in the extinction of many indigenous waterfowl. The wild mallard is the ancestor of most domestic ducks, and its naturally evolved wild gene pool gets genetically polluted by the domestic and feral mallard populations.
Taxonomy and evolutionary history
An American black duck (top left) and a male mallard (bottom right) in eclipse plumage
The mallard was one of the many bird species originally described in the 1758 10th edition of Systema Naturae by Carl Linnaeus.[2] He gave it two binomial names: Anas platyrhynchos and Anas boschas.[3] The latter was generally preferred until 1906 when Einar Lönnberg established that A. platyrhynchos had priority, as it appeared on an earlier page in the text.[4] The scientific name comes from Latin Anas, "duck" and Ancient Greek πλατυρυγχος, platyrhynchus, "broad-billed" (from πλατύς, platys, "broad" and ρυγχός, rhunkhos, "bill").[5] The genome of Anas platyrhynchos was sequenced in 2013.[6]
The name mallard originally referred to any wild drake, and it is sometimes still used this way.[7] It was derived from the Old French malart or mallart for "wild drake" although its true derivation is unclear.[8] It may be related to, or at least influenced by, an Old High German masculine proper name Madelhart, clues lying in the alternative English forms "maudelard" and "mawdelard".[9] Masle (male) has also been proposed as an influence.[10]
Mallards frequently interbreed with their closest relatives in the genus Anas, such as the American black duck, and also with species more distantly related, such as the northern pintail, leading to various hybrids that may be fully fertile.[11] This is quite unusual among such different species, and is apparently because the mallard evolved very rapidly and recently, during the Late Pleistocene.[12] The distinct lineages of this radiation are usually kept separate due to non-overlapping ranges and behavioural cues, but have not yet reached the point where they are fully genetically incompatible.[12] Mallards and their domestic conspecifics are also fully interfertile.[13]
Genetic analysis has shown that certain mallards appear to be closer to their Indo-Pacific relatives, while others are related to their American relatives.[14] Mitochondrial DNA data for the D-loop sequence suggest that mallards may have evolved in the general area of Siberia. Mallard bones rather abruptly appear in food remains of ancient humans and other deposits of fossil bones in Europe, without a good candidate for a local predecessor species.[15] The large Ice Age palaeosubspecies that made up at least the European and West Asian populations during the Pleistocene has been named Anas platyrhynchos palaeoboschas.[16]
Mallards are differentiated in their mitochondrial DNA between North American and Eurasian populations,[17] but the nuclear genome displays a notable lack of genetic structure.[18] Haplotypes typical of American mallard relatives and eastern spot-billed ducks can be found in mallards around the Bering Sea.[19] The Aleutian Islands hold a population of mallards that appear to be evolving towards becoming a subspecies, as gene flow with other populations is very limited.[15]
Also, the paucity of morphological differences between the Old World mallards and the New World mallard demonstrates the extent to which the genome is shared among them such that birds like the Chinese spot-billed duck are highly similar to the Old World mallard, and birds such as the Hawaiian duck are highly similar to the New World mallard.[20]
The size of the mallard varies clinally; for example, birds from Greenland, though larger, have smaller bills, paler plumage, and stockier bodies than birds further south and are sometimes classified as a separate subspecies, the Greenland mallard (A. p. conboschas).[21]

Duckling
The mallard is a medium-sized waterfowl species that is often slightly heavier than most other dabbling ducks. It is 50–65 cm (20–26 in) long – of which the body makes up around two-thirds – has a wingspan of 81–98 cm (32–39 in),[22]: 505 and weighs 0.7–1.6 kg (1.5–3.5 lb).[23] Among standard measurements, the wing chord is 25.7 to 30.6 cm (10.1 to 12.0 in), the bill is 4.4 to 6.1 cm (1.7 to 2.4 in), and the tarsus is 4.1 to 4.8 cm (1.6 to 1.9 in).[24]
The breeding male mallard is unmistakable, with a glossy bottle-green head and a white collar that demarcates the head from the purple-tinged brown breast, grey-brown wings, and a pale grey belly.[25] The rear of the male is black, with white-bordered dark tail feathers.[22]: 506 The bill of the male is a yellowish-orange tipped with black, with that of the female generally darker and ranging from black to mottled orange and brown.[26] The female mallard is predominantly mottled, with each individual feather showing sharp contrast from buff to very dark brown, a coloration shared by most female dabbling ducks, and has buff cheeks, eyebrow, throat, and neck, with a darker crown and eye-stripe.[22]: 506
Both male and female mallards have distinct iridescent purple-blue speculum feathers edged with white, which are prominent in flight or at rest but temporarily shed during the annual summer moult.[27] Upon hatching, the plumage of the duckling is yellow on the underside and face (with streaks by the eyes) and black on the back (with some yellow spots) all the way to the top and back of the head.[28] Its legs and bill are also black.[28] As it nears a month in age, the duckling's plumage starts becoming drab, looking more like the female, though more streaked, and its legs lose their dark grey colouring.[22]: 506 Two months after hatching, the fledgling period has ended, and the duckling is now a juvenile.[29] Between three and four months of age, the juvenile can finally begin flying, as its wings are fully developed for flight (which can be confirmed by the sight of purple speculum feathers). Its bill soon loses its dark grey colouring, and its sex can finally be distinguished visually by three factors: 1) the bill is yellow in males, but black and orange in females;[30][self-published source] 2) the breast feathers are reddish-brown in males, but brown in females;[30] and 3) in males, the centre tail feather (drake feather) is curled, but in females, the centre tail feather is straight.[30] During the final period of maturity leading up to adulthood (6–10 months of age), the plumage of female juveniles remains the same while the plumage of male juveniles gradually changes to its characteristic colours.[31] This change in plumage also applies to adult mallard males when they transition in and out of their non-breeding eclipse plumage at the beginning and the end of the summer moulting period.[31] The adulthood age for mallards is fourteen months, and the average life expectancy is three years, but they can live to twenty.[32]
Several species of duck have brown-plumaged females that can be confused with the female mallard.[33] The female gadwall (Mareca strepera) has an orange-lined bill, white belly, black and white speculum that is seen as a white square on the wings in flight, and is a smaller bird.[22]: 506 More similar to the female mallard in North America are the American black duck (A. rubripes), which is notably darker-hued in both sexes than the mallard,[34] and the mottled duck (A. fulvigula), which is somewhat darker than the female mallard, and with slightly different bare-part colouration and no white edge on the speculum.[34]
In captivity, domestic ducks come in wild-type plumages, white, and other colours.[35] Most of these colour variants are also known in domestic mallards not bred as livestock, but kept as pets, aviary birds, etc., where they are rare but increasing in availability.[35]
Owing to their highly 'malleable' genetic code, mallards can display a large amount of variation,[36] as seen here with this female, who displays faded or 'apricot' plumage.
A noisy species, the female has the deep quack stereotypically associated with ducks.[22]: 507 Male mallards make a sound phonetically similar to that of the female, a typical quack, but it is deeper and quieter compared to that of the female. When incubating a nest, or when offspring are present, females vocalise differently, making a call that sounds like a truncated version of the usual quack. This maternal vocalisation is highly attractive to their young. The repetition and frequency modulation of these quacks form the auditory basis for species identification in offspring, a process known as acoustic conspecific identification.[37] In addition, females hiss if the nest or offspring are threatened or interfered with. When taking off, the wings of a mallard produce a characteristic faint whistling noise.[38]
The mallard is a rare example of both Allen's Rule and Bergmann's Rule in birds.[39] Bergmann's Rule, which states that polar forms tend to be larger than related ones from warmer climates, has numerous examples in birds,[40] as in case of the Greenland mallard which is larger than the mallards further south.[21] Allen's Rule says that appendages like ears tend to be smaller in polar forms to minimise heat loss, and larger in tropical and desert equivalents to facilitate heat diffusion, and that the polar taxa are stockier overall.[41] Examples of this rule in birds are rare as they lack external ears, but the bill of ducks is supplied with a few blood vessels to prevent heat loss,[42] and, as in the Greenland mallard, the bill is smaller than that of birds farther south, illustrating the rule.[21]
Due to the variability of the mallard's genetic code, which gives it its vast interbreeding capability, mutations in the genes that decide plumage colour are very common and have resulted in a wide variety of hybrids, such as Brewer's duck (mallard × gadwall, Mareca strepera).[43]

The history of Yamaha Motorcycles
"I want to carry out trial manufacture of motorcycle engines." It was from these words spoken by Genichi Kawakami (Yamaha Motor's first president) in 1953, that today's Yamaha Motor Company was born.
"If you're going to do something, be the best."
Genichi Kawakami
Genichi Kawakami was the first son of Kaichi Kawakami, the third-generation president of Nippon Gakki (musical instruments and electronics; presently Yamaha Corporation). Genichi studied and graduated from Takachiho Higher Commercial School in March of 1934. In July of 1937, he was the second Kawakami to join the Nippon Gakki Company.
He quickly rose to positions of manager of the company's Tenryu Factory Company (musical instruments) and then Senior General Manager, before assuming the position of fourth-generation President in 1950 at the young age of 38.
In 1953, Genichi was looking for a way to make use of idle machining equipment that had previously been used to make aircraft propellers. Looking back on the founding of Yamaha Motor Company, Genichi had this to say. "While the company was performing well and had some financial leeway, I felt the need to look for our next area of business. So, I did some research." He explored producing many products, including sewing machines, auto parts, scooters, three-wheeled utility vehicles, and…motorcycles. Market and competitive factors led him to focus on the motorcycle market. Genichi actually visited the United States many times during this period.
When asked about this decision, he said, "I had my research division chief and other managers visit leading motorcycle factories around the country. They came back and told me there was still plenty of opportunity, even if we were entering the market late. I didn't want to be completely unprepared in this unfamiliar business so we toured to German factories before setting out to build our first 125cc bike. I joined in this tour around Europe during which my chief engineers learned how to build motorbikes. We did as much research as possible to insure that we could build a bike as good as any out there. Once we had that confidence, we started going."
The first Yamaha motorcycle... the YA-1.
"If you are going to make it, make it the very best there is." With these words as their motto, the development team poured all their energies into building the first prototype, and ten months later in August of 1954 the first model was complete. It was the Yamaha YA-1. The bike was powered by an air-cooled, 2-stroke, single cylinder 125cc engine. Once finished, it was put through an unprecedented 10,000 km endurance test to ensure that its quality was top-class. This was destined to be the first crystallization of what has now become a long tradition of Yamaha creativity and an inexhaustible spirit of challenge.
Then, in January of 1955 the Hamakita Factory of Nippon Gakki was built and production began on the YA-1. With confidence in the new direction that Genichi was taking, Yamaha Motor Co., Ltd. was founded on July 1, 1955. Staffed by 274 enthusiastic employees, the new motorcycle manufacturer built about 200 units per month.
That same year, Yamaha entered its new YA-1 in the two biggest race events in Japan. They were the 3rd Mt. Fuji Ascent Race and the 1st Asama Highlands Race. In these debut races Yamaha won the 125cc class. And, the following year the YA-1 won again in both the Light and Ultra-light classes of the Asama Highlands Race.
By 1956, a second model was ready for production. This was the YC1, a 175cc single cylinder two-stroke. In 1957 Yamaha began production of its first 250cc, two-stroke twin, the YD1.
The first Yamaha to compete in America (1957).
Based on Genichi's firm belief that a product isn't a product until it can hold it's own around the world, in 1958 Yamaha became the first Japanese maker to venture into the international race arena. The result was an impressive 6th place in the Catalina Grand Prix race in the USA. News of this achievement won immediate recognition for the high level of Yamaha technology not only in Japan but among American race fans, as well. This was only the start, however.
Yamaha took quick action using the momentum gained in the USA and began marketing their motorcycles through an independent distributor in California. In 1958, Cooper Motors began selling the YD-1 250 and the MF-1 (50cc, two-stroke, single cylinder, step through street bike). Then in 1960, Yamaha International Corporation began selling motorcycles in the USA through dealers.
With the overseas experiences under his belt, in 1960, Genichi then turned his attention to the Marine industry and the production of the first Yamaha boats and outboard motors. This was the beginning of an aggressive expansion into new fields utilizing the new engines and FRP (fiberglass reinforced plastic) technologies. The first watercraft model was the CAT-21, followed by the RUN-13 and the P-7 123cc outboard motor.
In 1963, Yamaha demonstrated its focus on cutting-edge, technological innovations by developing the Autolube System. This landmark solution was a separate oil injection system for two-stroke models, eliminating the inconvenience of pre-mixing fuel and oil.
Yamaha was building a strong reputation as a superior manufacturer which was reflected in its first project carried out in the new Iwata, Japan Plant, built in 1966. (The YMC headquarters was moved to Iwata in 1972.) Toyota and Yamaha teamed up to produce the highly regarded Toyota 2000 GT sports car. This very limited edition vehicle, still admired for its performance and craftsmanship, created a sensation among enthusiast in Japan and abroad.
Genichi said, "I believe that the most important thing when building a product is to always keep in mind the standpoint of the people who will use it." An example of the commitment to "walking in the customers' shoes" was the move in 1966 by Yamaha to continue its expansion. Overseas motorcycle manufacturing was established in Thailand and Mexico. In 1968, the globalization continued with Brazil and the Netherlands. With manufacturing bases, distributors and R&D operations in a market, Yamaha could be involved in grassroots efforts to build products that truly met the needs of each market by respecting and valuing the distinct national sensibilities and customs of each country. Yamaha continues that tradition, today.
By the late 1960s, Yamaha had quality products that had proven themselves in the global marketplace based on superior performance and innovation. Distribution and product diversity were on the right track. But Genichi knew that beyond quality, success would demand more. He had this view on the power of original ideas. "In the future, a company's future will hinge on ideas over and above quality. Products that have no character, nothing unique about them, will not sell no matter how well made or affordable…and that would spell doom for any company."
He also knew that forward vision, walking hand in hand with original ideas, would create an opportunity for the company and its customers that could mean years of happiness and memorable experiences. Genichi said, "In the business world today, so many people are obsessed with figures. They become fixated on the numbers of the minute and without them are too afraid to do any real work. But in fact, every situation is in flux from moment to moment, developing with a natural flow. Unless one reads that flow, it is impossible to start out in a new field of business."
A real-world illustration of this belief is the Yamaha DT-1. The world's first true off-road motorcycle debuted in 1968 to create an entirely new genre we know today as trail bikes. The DT-1 made a huge impact on motorcycling in the USA because it was truly dirt worthy. Yamaha definitely "read the flow" when it produced
"Make every challenge an opportunity."
Genichi Kawakami
the 250cc, single cylinder, 2-stroke, Enduro that put Yamaha On/Off-Road motorcycles on the map in the USA. The DT-1 exemplified the power of original ideas, forward vision, and quick action coupled with keeping in mind the customers' desires.
In years to come Yamaha continued to grow (and continues to this day). Diversity increased with the addition of products including snowmobiles, race kart engines, generators, scooters, ATVs, personal watercraft and more.
Genichi Kawakami set the stage for Yamaha Motor Company's success with his vision and philosophies. Total honesty towards the customer and making products that hold their own enables the company that serves people in thirty-three countries, to provide an improved lifestyle through exceptional quality, high performance products.
Yamaha Motor Corporation, USA Cypress, California
Genichi Kawakami's history with Yamaha was long and rich. He saw the new corporate headquarters in Cypress, California and the 25th Anniversary of Yamaha become a reality in 1980. He also watched bike #20 million roll off the assembly line in 1982. Genichi passed away on May 25, 2002 yet his vision lives on through the people and products of Yamaha, throughout the world.

Motorcycles VIN Decoder
A DIY audio electronics development platform. Very easy to plug things in and out of the breadboards and Arduino (duemilanove). Seeed Studio oscilloscope has proven to be a worthy tool. Now cooking: an arduino synthesizer, based on some simple waveform tables, homemade 8-bit DAC and bitwise modulation. Basically same as this but now much neater. Audio and video demos coming up, soon maybe... Here's an old demo, this one sounds roughly the same.

I added more yellow-green and sprayed some soft (not masked, but sprayed at an angle) highlights.
Not sure if I was daring enough as it's not very visible.
I've also touched in the road wheels in different greens, and sprayed a few in hull red for primer.

My primary (i.e. 99% of the time) use of the Sutra has been for commuting. I have covered over 2700 miles (4500km) in the time I have owned it. My commuting route through London is pretty tough on bikes - the roads south of the Thames are awful and full of potholes, through the City there is broken glass all over the place, and further north of the river there are speed-bumps everywhere. When I first got the Sutra she was wearing Continental Contact tyres, and they were pretty poor for commuting. They punctured easily and transmitted the bumpiness of the road right up into my forearms. Not much fun. After one puncture too many I replaced the tyres with Schwalbe Marathon Pluses, in their largest diameter, and the difference was marked. The increased volume of air provides a lot more cushioning for the arms, and I have not had a single puncture yet, despite having pulled 6mm long pieces of glass out of the tyre surfaces. The tyres are relatively heavy, but then so is the rest of the bike, and extra weight makes you stronger!
The original rear rack was pretty flimsy, and it did not allow the attachment of the Bikebin panniers I bought to try and add some rigidity. I ended up having to angle grind chunks out of the rack to fit the panniers, which can't have improved their structural integrity. After a month of experiencing the odd sensation of the bike wagging its tail whenever I stood up to pedal hard, I bit the bullet and upgraded the rack to a Tubus Logo. It was a tight fit with the rear disc brake, but the difference was immense. Gone was the sensation of a jelly-like bike, to be replaced by a sensation of rigid stability. Whilst the rack was expensive, it made all the difference, and I would highly recommend it.
Speaking of the brakes, they have saved my life on more than one occasion, usually when a Taxi decides to perform an emergency stop to pick up a fare. The brakes stop consistently in all conditions, and so far I have not had to replace the pads, although I think it will be time to do it soon. Not bad considering I have travelled almost five thousand kilometres in all weathers in the stop-start conditions of London. I was concerned that the brakes might be too powerful, but the modulation provided by the levers and the flex in the arm of the brake means that whilst the power is there if necessary, you have a lot of control over it. There is some disc drag, but this is owing more to my laziness than the brakes themselves, and seems to have little impact on cruising speeds.
Using the bike in all conditions has been excellent. The all-over fenders (something I have never fitted to a bike previously) really keep the rain off and eliminate spray from the road. I had to saw a bit of the front fender off to fit it over the larger tyres, and a little bit off the rear for the same reason, but after the modification they have been flawless.
I had heard reports of spokes snapping, and nothing happened to me until recently, when I noticed a detached spoke whilst replacing the rear cassette. I had no idea how long the spoke had been damaged for, and replaced it myself. The rear wheel is slightly askew, but it does not foul on anything, which is good considering the small tolerance between it and the fender. To be fair, I have been jumping off kerbs and sometimes it is impossible to miss a massive hole in the road when you are in busy traffic. An upgrade I am considering is a stronger rear wheel, although it is not pressingly urgent.
The ride of the bike is super smooth, and certainly not anything like the road bikes I am used to. I use my other road bike for triathlons, and whilst it is a lot more nimble, it is much less comfortable. The Sutra is comfortable all day long, owing in no small part to the Brooks B17 saddle, which took about two thousand miles to properly break in! It was worth it though - sitting on the bike is like sitting in an armchair (albeit a very odd armchair, but an armchair nonetheless). I tend to cruise at about 20mph on her, and my 10.5 mile commute to work takes about 37 minutes. I have started seeking out hills in preparation for some touring of Wales, and the Sutra certainly loves to climb. The aggressive, mountain-bike-like frame geometry no doubt assists in this, and is confidence inspiring when climbing and descending. The bar-con shifters were a novelty for me, but they make a lot of sense, especially if replacement shifters were needed on a tour. There are even bosses on the downtube to fit truly old-school shifters in an emergency.
The weight of the bike was a shock initially - weighing in at 15kgs without the accessories, she weighs significantly more than my Specialized Hardrock mountain bike, which is saying something! Over time I have become accustomed to the weight, and now it feels normal. The main advantage of this is that when I ride anything else, it feels super light and goes very rapidly. This makes this bike an ideal training steed.
In conclusion, I have found a lot to love about the Kona Sutra - she's tough, strong and surprisingly fast. There were some niggles about fitting add-ons, but they were all easy to overcome, and the result has been a reliable bike that I think will keep delivering for years.
Antonello da Messina (Messina, 1430 - Messina, February, 1479) was an Italian painter of the Italian Renaissance. He was deeply influenced by Early Netherlandish and Venetian painting. He served as apprentice in Messina and in Palermo before studying under Niccolò Colantonio in Naples, one of the most lively centres of Renaissance art. In 1457, he received his first commission as an independent painter, a banner for the Confraternità di San Michele dei Gerbini in Reggio Calabria. The first work to be signed and dated by him, the Salvator Mundi, was created in 1470. Among his most famous paintings are the Annunciation and Saint Jerome in His Study, which he painted in 1474.
Antonello's style is remarkable for its fusion of Italian simplicity with a Flemish concern for detail. He exercised an important influence on Italian painting due to his introduction and dissemination of Flemish painterly styles. His portraits are characterised by their modulation of light and shadow, as seen in this painting.

This steampunk or Victorian necklace started with a bit of Victorian ceiling tin with a pebbled pattern. I shaped it to resemble a honeycomb section before riveting on the over-sized bee. The bee was previously treated to a patina to create the color modulations. He appears to be holding an antique watch works wearing its own time-induced patina. A retaining ring was riveted behind the bee and fishing gear was added to provide movement in the piece. All this steamy delight hangs from an 18" section of chain that once supported a pendulum in a cuckoo clock. I am a trained, if somewhat buggy, silversmith and have built this piece to last.

The Synthex is a massive sounding and classic analog 8 voice synthesizer. This one in particular has the added MIDI feature. First off, It's interface is a dream to program. It has 30 knobs, 6 sliders, 80 switches and a joystick. Powerful sounds with 2 oscillators per voice, separate envelope generators, chorus and even a sequencer! The use of stable DCO's (digitally controlled analog oscillators) and oscillator cross modulation of Pulse Width and a multimode filter! The filter is based on the CEM3396 chip which was also featured in e.g. Oberheim's Matrix line of synthesizers.
There is a cool joystick that replaces traditional pitch/mod wheels and allows for greater variable real-time control over the two LFOs, oscillator and filter modulation. The 6 sliders beside the joystick assign what (LFO, osc and filter) goes to the joystick. Voices can also be layered or split across the keyboard. Other great features include the onboard digital Ring-Modulator, Chorus effect and Dual or Layer modes available. And also a four-track sequencer rounds out this synths host of features. The four different sequencer tracks can have different length, and sounds (Upper/Lower can be allocated to different tracks). Also it is possible to insert rests between notes as well as length of notes. Sequences and patches could be dumped to analog cassette tape through an audio interface. Two of it's tracks can output MIDI data.
The Synthex has three keyboard modes. 8 voice single sound (both Lower/Upper voices), Split with user selected split point (4 voices Lower/4 voices Upper) or Double which reduce the polyphony to four voices. Later versions implemented basic MIDI functions. Voices can also be layered or split across the keyboard.

I wanted to create an image that was a bit haunting, with some sensuality. The glow of the light and the darkness of the hands play well together by creating depth and mystery. Freeman mentions how black and white allows more expression in the modulation of tone, in conveying texture, the modeling of form, and in defining shape. I enhanced this photo with a levels adjustment, noise reduction, hue, and saturation.
Having owned the 2008 Kona Sutra for ten months, and just completed the first chain/cassette replacement, I thought it was about time for a long term review, to give other people an idea of what living with the Sutra has been like. My previous post explains why I chose the Sutra - I came up with what I thought was an impossibly eclectic list of requirements from a bicycle, and the Sutra ticked every single box.
Here's some specs, for the statophiles out there: Frame size C54cm Frame tubing Dedacciai COM 12.5 Butted Cromoly Fork Kona P2 700c TB Disc w/Lowrider Headset TH Crankarms FSA Gossamer MegaExo Chainrings 30/39/50 B/B FSA MegaExo Pedals Shimano PD-M520 SPD - Silver Chain Shimano HG53 --> Shimano HG93 XT Freewheel Shimano Deore (11-32, 9 Spd) --> Shimano XT M760 (11-32, 9spd) F/D Shimano Tiagra Triple R/D Shimano XT Shadow Shifters Shimano Bar-Con Handlebar FSA RD30 0S Stem FSA OS-190LX Grips Velo Wrap with Gel Brakes Avid BB7 Road Disc Brake Levers Shimano BLR-600 Front Hub Shimano M525 Disc Rear Hub Shimano M525 Disc Spokes DT Stainless 14g Tires Continental Contact 700 x 32C --> Schwalbe Marathon Plus 700x38c Rims Mavic A 317 Disc Saddle Selle Italia XO SE --> Brooks B17 Seatpost FSA SL-280 Seat Clamp Kona Clamp Rear Rack Tubus Logo Panniers Bikebins Computer Sigma DTS 1606 L Fenders SKS Chromoplastic
My primary (i.e. 99% of the time) use of the Sutra has been for commuting. I have covered over 2700 miles (4500km) in the time I have owned it. My commuting route through London is pretty tough on bikes - the roads south of the Thames are awful and full of potholes, through the City there is broken glass all over the place, and further north of the river there are speedbumps everywhere. When I first got the Sutra she was wearing Continental Contact tyres, and they were pretty poor for commuting. They punctured easily and transmitted the bumpiness of the road right up into my forearms. Not much fun. After one puncture too many I replaced the tyres with Schwalbe Marathon Pluses, in their largest diameter, and the difference was marked. The increased volume of air provides a lot more cushioning for the arms, and I have not had a single puncture yet, despite having pulled 6mm long pieces of glass out of the tyre surfaces. The tyres are relatively heavy, but then so is the rest of the bike, and extra weight makes you stronger!
The original rear rack was pretty flimsy, and it did not allow the attachment of the Bikebin panniers I bought to try and add some rigidity. I ended up having to angle grind chunks out of the rack to fit the panniers, which can't have improved their structural integrity. After a month of experiencing the odd sensation of the bike wagging its tail whenever I stood up to pedal hard, I bit the bullet and upgraded the rack to a Tubus Logo. It was a tight fit with the rear disc brake, but the difference was immense. Gone was the sensation of a jelly-like bike, to be replaced by a sensation of rigid stability. Whilst the rack was expensive, it made all the difference, and I would highly recommend it.
Speaking of the brakes, they have saved my life on more than one occasion, usually when a Taxi decides to perform an emergency stop to pick up a fare. The brakes stop consistently in all conditions, and so far I have not had to replace the pads, althoguh I think it will be time to do it soon. Not bad considering I have travelled almost five thousand kilometres in all weathers in the stop-start conditions of London. I was concerned that the brakes might be too powerful, but the modulation provided by the levers and the flex in the arm of the brake means that whilst the power is there if necessary, you have a lot of control over it. There is some disc drag, but this is owing more to my laziness than the brakes themselves, and seems to have little impact on cruising speeds.
Using the bike in all conditions has been excellent. The all-over fenders (something I have never fitted to a bike previously) really keep the rain off and eliminate spray from the road. I had to saw a bit of the front fender off to fit it over the larger tyres, and a little bit off the rear for the same reason, but after the modification they have been flawless.
I had heard reports of spokes snapping, and nothing happened to me until recently, when I noticed a detached spoke whilst replacing the rear cassette. I had no idea how long the spoke had been damaged for, and replaced it myself. The rear wheel is slightly askew, but it does not foul on anything, which is good considering the small tolerance between it and the fender. To be fair, I have been jumping off kerbs and sometimes it is impossible to miss a massive hole in the road when you are in busy traffic. An upgrade I am considering is a stronger rear wheel, although it is not pressingly urgent.
The ride of the bike is super smooth, and certainly not anything like the road bikes I am used to. I use my other road bike for triathlons, and whilst it is a lot more nimble, it is much less comfortable. The Sutra is comfortable all day long, owing in no small part to the Brooks B17 saddle, which took about two thousand miles to properly break in! It was worth it though - sitting on the bike is like sitting in an armchair (albeit a very odd armchair, but an armchair nonetheless). I tend to cruise at about 20mph on her, and my 10.5 mile commute to work takes about 37 minutes. I have started seeking out hills in preparation for some touring of Wales, and the sutra certainly loves to climb. The aggressive, mountain-bike-like frame geometry no doubt assists in this, and is confidence inspiring when climbing and descending. The bar-con shifters were a novelty for me, but they make a lot of sense, especially if replacement shifters were needed on a tour. There are even bosses on the downtube to fit truly old-school shifters in an emergency.
The weight of the bike was a shock initially - weighing in at 15kgs without the accessories, she weighs significantly more than my Specialized Hardrock mountain bike, which is saying something! Over time I have become accustomed to the weight, and now it feels normal. The main advantage of this is that when I ride anything else, it feels super light and goes very rapidly. This makes this bike an ideal training steed.
In conclusion, I have found a lot to love about the Kona Sutra - she's tough, strong and surprisingly fast. There were some niggles about fitting add-ons, but they were all easy to overcome, and the result has been a reliable bike that I think will keep delivering for years.
RCA model 1-XF-4 "Filteramic" AM/FM radio receiver, c. 1955.
Many people began bringing radio receivers into their homes in the 1920s. By the early 1960s most homes had at least one radio and often more. At that time amplitude modulation, or AM, served as the primary mode of broadcasting, but a newer mode that used frequency modulation, or FM, was becoming increasingly popular. Well-known industrial designer John Vassos created this radio for RCA in the 1950s.
+BEST BEFORE UNU +
¬Best Before Unu
UNU (Antonis Anissegos)
and BESTBEFORE (Andreas Karaoulanis) met in March 2010 on stage at a Festival in Thessaloniki, following the invitation of the festival director to perform together.
The match was instant and after the success of their performance, they decided to form the duo best before unu.
Since then they produced together many short audio/visual pieces, and performed often in Greece and in Germany.
The intensive electronics of unu found a visual counterpoint in the moving images of bestbefore, generating complex sonic-visual formations. While audio frequencies are analyzed and passed into image motions, which in turn feed back to the music, a never ending circulation of influence travels in both directions.
As an enrichment of the collaboration, best before unu appears also with live piano, adding an acoustic dimension to the creative process. A journey through morphing landscapes and imaginary organisms, stimulating the audience to continuously perceive new associations.

Ogundipe Fayomi's monument for Dr. Ronald Erwin McNair (1950–1986) combines a traditional bust with a uniquely shaped pedestal. McNair was the African-American astronaut, physicist, teacher, and musician who died aboard the Space Shuttle Challenger when it exploded on January 28, 1986.
This park, formerly known as Guider Park, was named for Dr. McNair in the same year as the Challenger disaster. The City’s Department of Cultural Affairs sponsored a competition through its Percent-for-Art program to choose an artist to create a central sculpture. They ultimately selected the Nigerian-born sculptor Fayomi, who fashioned a sensitive bronze portrait, set within a nine-foot tall polished red-granite pedestal resembling a modified rocket ship. The pyramidal base features bronze relief with images relating to Dr. McNair’s achievements and interests.
Dr. McNair was born on October 21, 1950, in Lake City, South Carolina. He graduated from Carver High School in Lake City in 1967, and received a B.S. degree in physics from North Carolina A & T State University in 1971. In 1976, Dr. McNair completed his Ph.D. in physics at the Massachusetts Institute of Technology (MIT). After graduating from MIT, Dr. McNair was employed as a staff physicist at Hughes Research Laboratories in Malibu, California. His work there involved developing lasers for isotope separation and photochemistry, using non-linear interactions in low-temperature liquids. He also conducted research on electro-optic laser modulation for satellite-to-satellite space communications and explored the scientific foundations of the martial arts. A member of numerous scientific organizations and a visiting lecturer in physics at Texas Southern University, Dr. McNair also taught karate as a fifth-degree black belt and was a performing jazz saxophonist.
In 1978, the National Aeronautics and Space Administration (NASA) selected Dr. McNair as an astronaut candidate. He completed his training the following year, and became eligible as a mission specialist astronaut on Space Shuttle flight crews. He first flew as a mission specialist on Mission STS-41-B on February 3, 1984, which featured the first untethered spacewalk. Serving as a mission specialist on Mission STS-51-L, his life was tragically cut short when the space shuttle exploded one minute and 13 seconds into the launch. After his death, the Dr. Ronald E. McNair Foundation for Science, Technology & Space Education was established in Atlanta, Georgia.
When this monument was dedicated on June 14, 1994, family, friends, former colleagues, community representatives, city officials and hundreds of school children gathered in memory of Dr. McNair’s legacy. The monument and the park, which was renovated at the time of the sculpture’s installation, evoke a mood in keeping with Dr. McNair’s wish inscribed on the pedestal. It reads, “that we should allow this planet to be the beautiful oasis that she is, and allow ourselves to live more in the peace she generates.”
Founding member and keyboardist of Pink Floyd, he passed away yesterday after a brief fight against cancer. This morning, in celebration of his life and his timeless contributions to the music world, I'm playing a few of the Pink Floyd classics he wrote, co-wrote or sang on. RIP Rick, thanks for all the music.
Dave Gilmour's website comments on Rick's passing
No one can replace Richard Wright. He was my musical partner and my friend.
In the welter of arguments about who or what was Pink Floyd, Rick's enormous input was frequently forgotten.
He was gentle, unassuming and private but his soulful voice and playing were vital, magical components of our most recognised Pink Floyd sound.
I have never played with anyone quite like him. The blend of his and my voices and our musical telepathy reached their first major flowering in 1971 on 'Echoes'. In my view all the greatest PF moments are the ones where he is in full flow. After all, without 'Us and Them' and 'The Great Gig In The Sky', both of which he wrote, what would 'The Dark Side Of The Moon' have been? Without his quiet touch the Album 'Wish You Were Here' would not quite have worked.
In our middle years, for many reasons he lost his way for a while, but in the early Nineties, with 'The Division Bell', his vitality, spark and humour returned to him and then the audience reaction to his appearances on my tour in 2006 was hugely uplifting and it's a mark of his modesty that those standing ovations came as a huge surprise to him, (though not to the rest of us).
Like Rick, I don't find it easy to express my feelings in words, but I loved him and will miss him enormously.

Nick Mason's comments on Rick's passing;
Losing Rick is like losing a family member - in a fairly dysfunctional family. He's been in my life for 45 years, longer than my children and longer than my wife. It brings one's own mortality closer. I'll remember Rick with great affection. He was absolutely the non-contentious member of the band and probably suffered for it. I wouldn't say he was easy-going, but he certainly never pushed to any aggravation. It made life a lot easier.
I first met Rick at the Regent Street College of Architecture. And I think Rick was always pretty much that same character I met in 1962. Rock'n'roll is a Peter Pan existence; no one ever grows up. Over a period, we gravitated towards the people who were less interested in architecture and more in going to the pictures and making music. The band happened a couple of years later. We all had very different ways of working. He always knew what he wanted to do and had a unique approach to playing. I saw an interview he did on TV, and he said it clearly: "Technique is so secondary to ideas." Roger [Waters] said the more technique you have, the more you can copy. Despite having some training, Rick found his own way.
To some extent, I think, the recognition for what he did in the band was a bit light. He was a writer as well as a keyboard player, and he sang. The keyboard in particular creates the sound of a band. By definition, in a rock'n'roll band people remember the guitar solo, the lead vocal or the lyric content. But a lot of people listen to our music in a different way. The way Rick floats the keyboard through the music is an integral part of what people recognise as Pink Floyd. He wrote "The Great Gig in the Sky" and the music for "Us and Them".
We were a very close-knit band and one always has the memory of that. We spent a lot of time together between 1967 and the mid-1970s. Rick was a very gentle soul. My image of Rick would be him sitting at the keyboard playing when all the fireworks were going on around him. That's the main quality one remembers, in a band where Roger and David [Gilmour] were more strident about what they believed should be done.
If there's something that feels like a legacy, it's Live 8 [July 2005, Hyde Park] and the fact that we did surmount any disagreements and managed to play together. It was the greatest occasion.
Roger Waters comment on Rick's passing;
"I was very sad to hear of Rick's premature death, I knew he had been ill, but the end came suddenly and shockingly. My thoughts are with his family, particularly [his daughters] Jamie and Gala and their mum Juliet, who I knew very well in the old days, and always liked very much and greatly admired.
"As for the man and his work, it is hard to overstate the importance of his musical voice in the Pink Floyd of the '60s and '70s. The intriguing, jazz influenced, modulations and voicings so familiar in 'Us and Them' and 'Great Gig in the Sky,' which lent those compositions both their extraordinary humanity and their majesty, are omnipresent in all the collaborative work the four of us did in those times. Rick's ear for harmonic progression was our bedrock.
"I am very grateful for the opportunity that Live 8 afforded me to engage with him and David [Gilmour] and Nick [Mason] that one last time. I wish there had been more."
ECHOES...
"Overhead the albatross hangs motionless upon the air
And deep beneath the rolling waves
In labyrinths of coral caves
The echo of a distant time
Comes willowing across the sand
And everything is green and submarine.
And no-one called us to the land
And no-one knows the wheres or whys
But something stirs and something tries
And starts to climb towards the light
Strangers passing in the street
By chance two separate glances meet
And I am you and what I see is me
And do I take you by the hand
And lead you through the land
And help me understand the best I can
And no-one calls us to move on
And no-one forces down our eyes
And no-one speaks and no-one tries
And no-one flies around the sun
Cloudless everyday you fall upon my waking eyes
inciting and inviting me to rise
And through the window in the wall
Come streaming in on sunlight wings
A million bright ambassadors of morning
And no-one sings me lullabies
And no-one makes me close my eyes
And so I throw the windows wide
And call to you across the sky..."

Automatic Frequency Control. (AFC) - method or device to keep a radio or television receiver automatically tuned to a desired frequency or channel. Assuming that the receiver is at least approximately tuned to the desired frequency, a circuit in the receiver develops an error voltage proportional to the degree to which the receiver is mistuned. This error voltage is then fed back to the tuning circuit in such a way that the tuning error is reduced. In most frequency modulation (FM) detectors an error voltage of this type is easily available. In an FM receiver, automatic frequency control (AFC) may make it difficult to receive a weak signal located near in frequency to a strong one.

I had a Coleco when I was a little boy, and I absolutely loved this stupid game, and its screeching theme music, which is not the "tra LAAA la-laaa la la" music from the show. I'd find myself whistling this digital tune set all the time. Each section of the world had its own music that would cut in replacing the last bit whenever you switched backgrounds, which occurred every 2 screens or so. The musical bits were constructed of short, roughly 10-second loops, and so could conceivably annoy the crap out of parents if you played too long.
I had Donkey Kong there, too, but none of the other few on the table. One of the cool things about the Coleco was their Atari adapter, which they were eventually sued over. There's a port on the front of the Coleco, centered horizontally in front of the cartridge hole into which you could plug the wedge-shaped Atari adapter, and then you could stick Atari 2600 games into that, and it had its own reset buttons, etc. As such, I never actually had an Atari 2600, though I had original joysticks, and several of the games. It's weird, because I've ended up with strong nostalgic feelings for this other system I never actually owned.
