L'aggressività è molto importante negli animali. Essa consente agli individui più forti di prevalere su quelli meno dotati e di trasmettere i loro geni, a beneficio della specie cui appartengono. E consente, ancora a questi stessi, di avere un accesso prioritario alle fonti alimentari. Il Sistema Vivente ha messo a punto questi dispositivi per garantire la sua massima efficienza. Ma tutto questo non può valere per l'Uomo ..... ..
Dhobi Ghat - Mumbai‘s 140-year-old, open-air laundromat where it is estimated that each day over half a million pieces of clothing are sent there from hotels, hospitals, and homes to be washed, dried, folded and returned! At first glance Dhobi Ghat seems chaotic. But there is order in this chaos. Washermen called dhobis wash clothes and hang them out to dry in a manner that optimizes both time and space. Each article has a code written on its back that allows the correct piece of laundry to get back to its owner. This system is amazingly efficient and one of the main reasons for Dhobi Ghat ’s popularity.
Cleo still likes to play but she would NEVER run after a toy. As she is an energy efficient creature she prefers to play while she is comfortably lying on a cushion and only has to lift the paw to catch the toy. Cleo has always tried to avoid any waste of energy, even 16 years ago when she was a kitten....

Noi umani siamo osservatori grossolani, anche in ragione di sensi di efficienza assai inferiore a quelli di numerose specie animali, ma soprattutto per l'incorreggibile superficialità che ci distingue. Questi alberi, questi cipressi, ad esempio, sembrano a prima vista tutti uguali. Invece sono tutti diversi: ciascuno, proprio come accade agli individui della nostra specie, esprime la propria individualità ..... ..
Accade al volte di osservare banali "oggetti viventi" e di scoprirne la sovrumana perfezione. Si prenda ad esempio una foglia, una foglia di noce come in questo caso e la si esamini nel particolari. Ci si renderà conto che non esiste struttura a pannelli solari creata dall'uomo che possa uguagliarla. E' perfetta, efficiente e persino bella; il tutto quasi a dispetto del primate che si dice cultore e creatore della Bellezza ..... ..
Gli occhi delle libellule sono portentosi. Strumenti sovradimensionati rispetto al corpo dell'organismo ospite, essi consentono alle diverse specie una notevole efficienza predatoria e, al tempo stesso, una elevata capacità di controllo dell'ambiente circostante. Questo presenta anche il vantaggio di potersi sottrarre efficacemente all'attenzione dei predatori, che sono numerosi e sempre in agguato ..... ..
A title with more than one meaning. The history of the Clinchfield makes it the most "modern" route in American Railroading. The C&O between Russell and Elkhorn City, KY already existed, and at the turn of the Century entities laid out plans to make a hyper efficient route to the Southeast. No such route existed.
The story of the Pikeville cut also continues with the theme of straight shootin'. I believe the Chessie along with the Commonwealth of Kentucky planned to bypass downtown Pikeville in the 70s. The subsequent route is pictured here with US 23 and the Levisa Fork also jammed in there. M693 is moments away from yarding at Shelby. A new crew will come on board later during the night. A soppy one at that...

When Mr. Lewis needed a barn for his large livestock herd,he thought "outside the box",and built a more efficient round barn which was on his family farm till the 1990's.At that time,the family decided for it to survive,it needed to be donated to an organization who would maintain it.It ended as a part of the Adams County,IL. fairgrounds along with many other historic subjects-an old one room schoolhouse and an old general store some examples...
The Lewis Barn is on the National Register of Historic Places...

The ocelot (Leopardus pardalis) is a medium-sized spotted wild cat that reaches 40–50 cm (16–20 in) at the shoulders and weighs between 7 and 15.5 kg (15 and 34 lb) on average. It is native to the southwestern United States, Mexico, Central and South America, and the Caribbean islands of Trinidad and Margarita. Carl Linnaeus scientifically described it in 1758. Two subspecies are recognized.
The ocelot is efficient at climbing, leaping and swimming. It prefers areas close to water sources with dense vegetation cover and high prey availability. It preys on small terrestrial mammals, such as armadillos, opossums, and lagomorphs. It is typically active during twilight and at night and tends to be solitary and territorial.
Both sexes become sexually mature at around two years of age and can breed throughout the year; peak mating season varies geographically. After a gestation period of two to three months, the female gives birth to a litter of one to three kittens. They stay with their mother for up to two years, after which they leave to establish their own home ranges.
The ocelot is listed as Least Concern on the IUCN Red List and is threatened by habitat destruction, hunting, and traffic accidents. While its range is very large, various populations are decreasing in many parts of its range. The association of the ocelot with humans dates back to the Aztec and Incan civilizations; it has occasionally been kept as a pet. – Wikipedia
In Terneuzen ging uiterst efficiënt de 6463 meteen weer los retour Sas van Gent. De set Tads'en zou de rest van de ochtend één van de drie sporen op Terneuzen Zuid blijven blokkeren. Ondertussen waren de Lineas loccen die in het weekend overstaan met de suikertrein los vanuit Axel naar Terneuzen gekomen om de Blauwe Kade van Verbrugge te bedienen. Er werd een homogene sleep knikketelwagens uitgehaald, waarna er nog een set geplaatst moest worden die op de noodzijde stond opgesteld. De uitgehaalde wagens konden echter niet op Terneuzen Zuid worden achtergelaten, want dan zouden beide sporen waarvan je naar de kade kan bezet zijn. En dus werden de uitgehaalde meegenomen naar de noordzijde. Het tweetal 77'ers komt hier aan met de knikketels; achter deze wagens staat de set die nog geplaatst moest worden. Op de achtergrond wordt druk gewerkt aan een nieuwe sluis in het kanaal.

The dragonflies are wonderful. They are very efficient predators, they can intercept prey mid-air, they can move each of their four wings independently from the others, they have near-360-degree vision with their eyes which contain 30,000 facets, each bringing in information about the insect's surroundings. Top of it they're beautiful insects :)

Thank you very much for viewing my photos, I appreciate the faves and comments!
I composed this image of an abandoned historic farm building while visiting the hamlet of Rowley, Alberta (population 11), a place now characterized as an Alberta ghost town.
For those interested, the history of this town is presented below.
Rowley (like many other prairie towns) was settled around 1910 by the families of nearby farmers to efficiently collect and load farm products onto trains bound for Calgary. The soils in the Rowley region are ideal for agriculture due to their high fertility.
It wasn’t long before the town of Rowley became a hub of activity: large fields were planted, harvested, and transported through the Rowley train station. Between 1915 and 1929, the local farmers built stores, banks, and other services in town so that they didn’t have to travel long distances to get what they needed. A school, post office, and church were built and Rowley was officially connected by rail to the rest of the province.
The Great Depression experienced across the entirety of North America had no mercy on its relentless tear across western towns. Rowley was no exception to the struggles of widespread drought and market collapse.
The grain industry lost most of its value. Farmers – used to dealing with hardships – toughed the economic ruin out and did their best to provide for their families and continue building the community despite the market. Farmers who had overextended themselves upgrading their farms and livelihoods were left being unable to afford the upkeep of their farm and business in town began to close.
By the 1940s people started packing up their belongings and using that new train station to leave town. Rowley, Alberta was in decline. The municipal district office was moved out of Rowley and fires had leveled many homes and businesses.
When Alberta’s highway system was constructed in the 1950s, Rowley was bypassed entirely and left behind. These roads made it easy for young people to leave Rowley in favour of Drumheller, Calgary, or Edmonton. In the 1950s, both the hotel and curling rink burned down and were never replaced. The school and railway station both closed down in 1965.

The Damme Canal (French: Canal de Damme. Dutch: Damse Vaart or Napoleonvaart) is a canal in the Belgian province of West Flanders. The canal links Bruges with the Western Scheldt at Sluis (now across the frontier in The Netherlands). It was constructed on the orders of Napoleon Bonaparte who wished to create a canal network in order to permit the efficient transport of troops without the risk of disruptive interventions from the British navy.
Following the defeat of Napoleon, the original strategic imperative for the canal was removed. The plans in the Napoleonic era had called for a link to the Scheldt at Breskens. Half a century later the canal opened to traffic in 1856, and the link with the sea had moved to Sluis.
At Damme the canal crosses the Leopold Canal and the Schipdonk Canal, both of which were dug in the middle years of the nineteenth century in order to reduce the vulnerability of the Belgian canal network to Dutch interference, after the achievement in 1830 of Belgian independence. It was necessary to create a system of Siphons because of the differences in water level of the three canals. The canal was used until 1940 when French troops destroyed the siphon system: this put an end to maritime transport on the Damme Canal.
After war use of the canal resumed, but it was used now by pleasure boats, along with a tourist boat connecting Damme and Bruges.
Learning how to skillfully and efficiently handle an as wide as possible range of photo - processing tools is an additional reason that turned me into a "serious" lover of the art of photography ... All advanced digital photo-processing programs and their related plugins form literally a whole new world ready to help you present effectively and successfully whatever is imprisoned into your Micro SD drive via your camera's sensor ..
I don't like modifying the capture's fundamental traits ... I also strongly dislike removing or even adding elements that weren't there in the first place ... But I very much enjoy creating a low light surrounding ambient atmosphere that exhales tranquillity and helps revealing all the effort hidden behind the scene's capture ... I like stressing out the subtle contrast between the light around the frame's main point of interest and its surrounding environment ...
I enjoy giving special attention to every single detail of any image I find worthy enough to be exhibited in front of your eyes ...

Griffon vultures have been used as model organisms for the study of soaring and thermoregulation. The energy costs of level flight tend to be high, prompting alternatives to flapping in larger birds. Vultures in particular utilize more efficient flying methods such as soaring. Compared to other birds, which elevate their metabolic rate to upwards of 16 times their basal metabolic rate in flight, soaring griffon vultures expend about 1.43 times their basal metabolic rate in flight. Griffon vultures are also efficient flyers in their ability to return to a resting heart rate after flight within ten minutes.
As large scavengers, griffon vultures have not been observed to seek shelter for thermoregulation. Vultures use their bald heads as a means to thermoregulate in both extreme cold and hot temperatures. Changes in posture can increase bare skin exposure from 7% to 32%. This change allows for the more than doubling of convective heat loss in still air. Griffon vultures have also been found to tolerate increased body temperatures as a response to high ambient temperatures. By allowing their internal body temperature to change independently of their metabolic rate, griffon vultures minimize their loss of water and energy in thermoregulating. One study in particular (Bahat 1995) found that these adaptations have allowed the Griffon vulture to have one of the widest thermal neutral zones of any bird.
It declined markedly throughout the 19th–20th centuries in much of Europe, North Africa and the Middle East, mainly due to direct persecution and "bycatch" from the poisoned carcasses set for livestock predators (Snow and Perrins 1998, Ferguson-Lees and Christie 2001, Orta et al. 2015). In some areas a reduction in available food supplies, arising from changes in livestock management practices, also had an impact (Ferguson-Lees and Christie 2001, Orta et al. 2015). It is very highly vulnerable to the effects of potential wind energy development (Strix 2012) and electrocution has been identified as a threat (Global Raptors Information Network 2015). Non-steroidal anti-inflammatory drugs (NSAIDs) used for veterinary purposes pose a threat to this species. One case of suspected poisoning caused by flunixin, an NSAID, was recorded in this species in 2012 in Spain (Zorrilla et al. 2015). Diclofenac, a similar NSAID, has caused severe declines in Gyps vulture species across Asia.

The efficient bus took me to Monnickendam, 12 km to the north of Amsterdam. Don't let me bore you with my findings about that small medieval city, today a thriving summertime harbor. Instead, allow me to tell you about my pleasant hike south on the Zeedijk which protects Waterland from the sometimes violent waters of what was once the Zuyderzee but now called the Markermeer since the great dike - Afsluitdijk - that closed the 'Zee' off from the North Sea.
That 'Sea Dike' took me along the Gouwzee which separates the island of Marken due east from the mainland. I continued onward to Zuiderwoude and finished my hike at Broek in Waterland, whence a bus carried me back to the City.
Walking on that dike I for the first time actually experienced the fact that much of the land here is below sea level. But the day was pleasant - though blowing a nasty cold wind - and the colors fabulous. Of course I didn't hesitate to take a dip among the other Old Coots - Fulica - which you can see right by my muddied waters. As I lay drying in the Sun, my eyes set on the greens of not yet blossoming Queen Anne's Lace, Anthristicus sylvestris, with its beautiful delicate hairs. And here he was, too, large-eyed Bibio marci, St Mark's Fly (St Mark's feastday is on April 25, in just a few days). He's really beautiful and just about ready, i would think, to find his small-eyed female partner. But I didn't stay to watch...
