I hadn't intended to produce a second example of Sunderland District's HUP-C Leyland Leopards, but a simple swap of front panels enabled Northern's CCD 714D to be presented as HUP 947C. This is how it appears (without the lower grille originaly fitted) on page 45 of 'Northern General and its Subsidiaries - From No Place to Success' (Autobus Review Publications). To quote from the caption to that image:
"New to Sunderland District in 1965 and fitted with BET-style dual-purpose bodywork, Leyland Leopard 347 (347 HUPC) is seen here wearing its original light blue and cream, livery. Transferred to Northern upon its absorption of Sunderland District on 1 January 1975, it was repainted into NBC poppy red and renumbered 4304. It was withdrawn in 1978." (08-Feb-10)

Absorption nebulae or dark nebulae are clouds of gas and dust that don’t emit or reflect light, but block light coming from behind them. These nebulae tend to contain large amounts of dust, which allows them to absorb visible light from stars or nebulae beyond them. Astronomer William Herschel, discussing these seemingly empty spots in the late 1700s, called them “a hole in the sky.”
These opaque, dark knots of gas and dust called "Bok globules" are absorbing light in the center of the nearby emission nebula and star-forming region, NGC 281. Bok globules may form stars, or may eventually dissipate.

Today is a critically important day: Ukrainian Independence Day. The modern, democratic, free nation of Ukraine was born on August 24th, 1991 with the signing of their Declaration of Independence. It also marks exactly six months since the start of the all-out invasion from Russia.
A while back, knowing that this existential conflict was likely to last a long time, I ordered some sunflower seeds. Not your average variety, mind you, this is a special “white sunflower”, a cultivar known as “ProCut White”. Years ago, I was given a tip that white sunflowers are some of the most beautifully fluorescent; This tip has just been proven correct. While the pollen of that particular species does not seem to fluoresce, the petals certainly put on a light show!
I have seen “electric blue” lines in some flower petals before (snowdrops), but the two-tone colours of the petals themselves is something I’ve only observed in flowers directly related to sunflowers. The reason for these fluorescent colours is simply a byproduct of the method for which the flowers absorb UV light. Sunflowers have a “black” center, including half the petals, and bright white external portions of the petals when observed in UV light directly – which many pollinators can see. And there are two ways for a flower to appear “black” in UV: direct absorption, or fluorescence into the visible spectrum, such that the UV light becomes lower-energy visible light. That’s the science behind these “by-product” colours, but then also happen to match very closely to the national colours of Ukraine.
In support of Ukraine’s continued battle, I place this image into the Public Domain. It’s currently my phone’s lock screen image, and you may wish to do them same. Use it for anything you’d like, personal or commercial. Spread it far and wide.
Today is also an ominous day. There is word that Russia has closed its airspace in the western-most territories in anticipation of some event today. Kyiv has placed restrictions on mass gatherings. It would be very symbolic for Russia to attempt something horrific today, and I sincerely hope nothing materializes. We’ve seen a few missiles launched, but that’s sadly an every-day occurrence. Russia’s forces continue to be decimated, so any escalation could have some level of desperation associated with it.
In Russia, the middle-class are finally afraid. They fear restrictions on their travel to other countries, and they fear direct attacks on their homes in places like Crimea, which they have been fleeing after Ukraine has made a number of successful attacks in the occupied region. The Russian elites no longer feel safe either, after the car bombing in Moscow that took the life of Darya Dugin, a philosopher and political theorist who was very much in support of Putin’s actions. Her father, Alexander Dugin, is one of Putin’s top ideologists. It sends a very clear message: regardless of social class, you are not completely safe. This fear can become a powerful threat to Putin’s regime, if it can be escalated properly. Increasingly, it appears that Ukraine is holding all the cards, but they still need more help.
Slovakia is sending 30 T-72 tanks to Ukraine after Germany agreed to send them 15 modern Leopard II tanks. New aid packages from many countries including Canada, Sweden, and the United States have been announced. There are reports that Saudi Arabia is returning the Grim-2 missile systems it purchased from Ukraine, some of the most modern long-range systems in existence. The range here is the critical factor: 500km maximum range. The distance between Ukrainian controlled territory in the North, say Hrem’yach, directly to The Kremlin in Moscow, is 473 kilometers.
If Ukraine does indeed have the Grim-2 system, with the longest-range ammunition, they could be in striking distance of Moscow. Would taking such action be a smart move? I don’t think so. However, the possibility alone can bring a layer of much-needed fear to Russia. The hubris cultivated from previous imperialistic gains is eroding. Ukraine will win this war, thanks to the world coming to its aide. It’s far from over yet, as the area controlled by Russia is larger than the majority of nations in Europe.
The fight continues, and today should be a day to celebrate the heroes of Ukraine, both past and present. Show your support!
And on a personal note, I have discovered that I have living relatives in Ukraine. Specifically, my paternal great-grandfather’s cousin who still carries the same last name (it changed a bit when my ancestors emigrated from Ukraine, the original is Komarychko). Likely due to some people having children later in life, his generation has all but disappeared. Soon I hope to have a conversation with him via a translator, and eventually visit the village at the center of my Ukrainian roots where he still lives.
Messier 52 (also known as NGC 7654) is an open cluster in the Cassiopeia constellation. It was discovered by Charles Messier in 1774. M52 can be seen from Earth with binoculars.
Due to interstellar absorption of light, the distance to M 52 is uncertain, with estimates ranging between 3,000 and 7,000 light years. One study identified 193 probable members of the cluster, with the brightest member being magnitude 11. (text: en.wikipedia.org/wiki/Messier_52)

This 360° panorama was captured from the Atacama Desert in Chile, one of the most suitable places on Earth for astronomical observation, and more precisely from the European Observatory of "La Silla". Note that the dome in the foreground is the home of the TRAPPIST Telescope, which discovered the famous system of 7-earth-size exoplanets around a red-dwarf star called TRAPPIST-1!)
Anyway, this image not only shows the Milky Way spanning over the entire field of view but also an impressive amount of strange colorful wave-like structures in the whole sky!
This orange/red light emitted at 85 km altitude (and higher) does not originate from artificial light pollution or high altitude clouds.
This rare phenomenon called Airglow is entirely natural and originates from an interaction between the Ultra-violet light of our Sun and the particles of the upper layers of the atmosphere.
During the day, the highly energetic UV light of the sun hits the atoms of oxygen, sodium, nitrogen...etc of the Earth's atmosphere. This absorption of energy puts them in an excited state that only waits for an external process to be able to release this excess of energy.
Using Chemiluminescence, the atoms of the atmosphere are slowly releasing this absorbed UV-llight into visible light, before going back to their stable energy state.
The emission of light, whose color depends on the chemical element involved in the reaction (oxygen for red airglow, sodium for green airglow), continues even during night-time when the sun has set for few hours.
As a fluid, Airglow follows the air flow of the atmosphere and the variation of gravity field caused by the topography of the ground, which produces the so-called "gravity waves" (not gravitational waves!).
These gravity waves are what make the main spatial feature of airglow in the sky: wave-like and ripple-like structures, with strong inhomogeneities.
Red and orange airglow (even a little bit of green) were very strong during that night in Chile! Even though this natural phenomenon is very common in this region of the world, it is usually not as intense as it was during that night!
You can also spot the zodiacal light, a tilted cone of blue light starting from the lower horizon and extending to the galactic center.
This leads to a new definition of what a high-quality sky for stargazing really is: not a dark-sky but a sky under which the rarest and the dimmest natural phenomena can be seen, revealing the true colors of the sky!
The two photographers next to the TRAPPIST observatory are Norédine and Olivia, two astronomy social enthusiasts of our group of 8 which was chosen by ESO to participate to its #MeeESO event.
The other observatories visible in this image are (from right to left) : the Danish 0.5-meter telescope, the ESO-0.5-meter telescope, the ESO-1.52-meter telescope and finally the tiny illuminated dome in the top horizon is the huge ESO-3.6-meter telescope.
17 images were captured and stitched together to form this 360° panoramic view. Neither photo blending/digital art nor over-exaggerated colors/contrasts. The success of this panorama holds in the fact that I used an ultra wide angle lens : a Sigma 14 mm F/1.8 which enabled me to capture far less images and to spend far less time than if I had used a standard lens (35 mm focal length).

The blue hour occurs when the Sun is far enough below the horizon so that the sunlight's blue wavelengths dominate due to the Chappuis absorption caused by ozone. (Wikipedia)
Bridge #150 (Hatter's Bridge) on the Leeds-Liverpool Canal near Salterforth, Lancashire, UK, during the weekend's fog and frost
Hatter's Bridge is so named because Foulridge had a flourishing cottage industry of felt hat making from the 17th century.
(The term "mad as a hatter" comes from the use of mercury in the production of felt hats in the 18th and 19th centuries, where absorption of mercury through the skin can cause neurological disorders.)

Look at all that inorganic and mathematical grain!
So I was bored at work. And as you do, I looked up the science behind film grains. The noise in the dark part of the image are in fact statistical quantum fluctuations which arise due to the absorption of photons by the silver halide crystals in the film. It follows a random Poisson distribution. Similarly, noise in the light areas follows a random binomial distribution.
Interestingly, both the Poisson and the binomial distribution can be approximated by a normal distribution (or a Gaussian) under different conditions. The Gaussian is an isotropic (i.e. uniform on all sides, so it spreads out like a chocolate orange) distribution and the Lightroom/Photoshop-generated grains certainly look like it - or in quasi-witchdoctor photo-speak, lacking in soul.. (presumably)
I think this is the reason some photographer think the film grain is "organic". This is because the distribution of silver halide grains in the film exists in a phase-separation field* (i.e. it isn't uniform) and so the grain patterns are not in fact uniform Gaussians nor isotropic, which Lightroom tries to mimic.
Now that we can sort of quantify this intangible film organicity thing, it's kind of interesting to see(lol) that our eyes can spot the subtle differences between the computer generated grain and a quantum-fluidic instability.
Anyway, take-home msg is probably that “biology is somewhat physics” - so you can imagine I was like an overexcited silver halide crystal in a bath of Portra 400 emulsions when they said the same thing on Star Trek discoveries. Now if only Netflix made a Star Wars one.. :)
*I work with phase-separation fields.

Anyway, this pic is awesome :-)

Louviere + Vanessa
inkjet on German etching paper from distressed negative
What is it? a traditional photographic image on film. The film has then been "distressed" and printed or scanned. The resulting scan was printed using a inkjet on to German Etching paper which is acid- and lignin-free, coated on one side to recieve inkjet ink without undue absorption.
Jeff Louviere is from New Orleans, Vanessa is from New York and they met each other half-way, in Savannah. Jeff graduated from the Savannah College of Art and Design during which he and 3 other artists created the world’s largest painting, a 76,000 square foot image of Elvis which was included in the Guinness Book of World Records. Vanessa began photographing at age 12 and won a Kodak International Award of Excellence in Photography when she was 17. She photographed through Italy and Greece before graduating from Rochester Institute of Technology with a degree in Photography.
The night sky is full of strange things:
This is the Bubble Nebula.
The bubble is created by the stellar wind from a massive hot young central star. Energetic radiation from the star ionizes the shell, causing it to glow in the wavelength of H ll.
About six light-years in diameter, the nebula is near a giant molecular cloud which contains the expansion of the bubble nebula while itself being excited by the hot central star, causing it to glow. It was discovered in 1787 by William and is located at a distance of 7100 light years in the the constellation Cassiopeia.
Also visible in the same field of view is the open cluster M52. Due to interstellar absorption of light, the distance to M52 is uncertain, with estimates ranging between 3,000 and 7,000 light years.
On the right edge of the image is NGC7538, another H ll nebula, which is home to the biggest yet discovered protostar (a collapsing ball of rotating gas that’s on the way to becoming a star) which is about 300 times the size of the Solar System. The distance to NGC7538 is estimated at around 9100 light years.

Thanks for all your comments and faves. They are highly appreciated!
(+1 thats a little bit different in comments)
Ok, so I realised that the fish tank in my living room now has an amazing light in it because we had to put the lid back on it! I got this totally wacky idea on saturday after an amazing day at Imogens photoshoot. I became a little less scared to do something different. Im actually really happy with this! aaand i barely even edited it which is always a bonus! :D haha!
Ohhh i was tagged...ill do that next photo!

Poem.
The mercury greys, the tree-lined ebony silhouettes, deep indigo and silver-coated marbling, gleaming, beaming off the cloud-reflected bay-
Dazzles and spell-binds.
That precious God-given ambience of early dawn blinds us but etches blurred images of heavenly proportions to our senses.
The mesmerising light, the near-silent water’s edge only broken by the lilting call of the oyster-catcher or the muffled comments of stirring sailors aboard their dreamy yachts.
These familiar sounds, the salt-laden odours of a near-calm bay and the silent, gentle absorption of the sun’s rays rouses and energises a myriad of life-forms to a glorious new day.
To witness this scene is pure bliss.
To hear, feel and sense it, is almost indescribable.
The rising Full "Wolf" Moon of January 6, 2023 over the Badlands of Horseshoe Canyon, near Drumheller, Alberta. The sequence demonstrates the changes in colour of the rising Moon from atmospheric absorption, and changes in its shape from atmospheric refraction.
This night the Moon was full almost at the same time as it rose from my location. However, the Moon's high northerly declination — it was about 4° north of the ecliptic — meant that it rose far to the northeast and some 30 minutes before the Sun set, despite the Moon being opposite the Sun. As such, even for the last shot, with the Moon several Moon diameters in altitude, the Sun was still up and lighting the landscape. In fact, at that time the Sun broke through clouds in the southwest to light the foreground with warm light.
In this blend, the ground and majority of the sky comes from the final image with the highest Moon and warmest landscape lighting. For the earlier shots the Moon came up in a very bright sky. And so, to better represent the scene, some of the sky coloration — the magentas and cyans — comes from earlier exposures blended in with broad-brush masks. Dark anti-crepuscular rays also added subtle sky colouration and bands of darker blue.
This is a sequence of 9 images at an interval of 2.5 minutes, extracted from a set of 80 frames taken every 15 seconds with the camera on automatic exposure, as the sky and ground remained bright enough for an accurate meter reading. The first 8 Moons are masked and layered in with a Lighten blend mode.
All images were the Canon R5 at ISO 125 and Canon RF100-400mm lens at 281mm and f/8. Most processing in Adobe Camera Raw with ground and sky masks. Glow and dynamic contrast filters added with ON1 Effects plug-in.
Though Blondin's claim that he was a direct descendent of Charles Blondin was a little dubious. That they had grown up in the same Pas-de-Calais region of France did give some credence to the claim, that absorption of the same air, earth and water, fed by the bodies of their collected common ancestors, that mountain of DNA, of mulch.
Memo to Marcel: Nose hair alert!
Excerpt from youractionsmatter.ca/bee-thankful/:
Bee Thankful
• Bees are vital to the preservation of ecological balance and biodiversity in nature. They provide one of the most recognizable ecosystem services, pollination, which is what makes most food production possible.
• One third of all the food we eat depends on bees, and of the 100 crop varieties that provide 90% of the world’s food, 71 are pollinated by bees.
• Honeybees alone pollinate 80% of all flowering plants, including more than 130 types of fruits and vegetables.
• The journey of bees begins with manure and fertilizer. It is used to enrich the soil, providing essential nutrients that help seeds germinate and plants grow.
• Water, a fundamental element for life, aids in the absorption of these nutrients from the soil, allowing the plant to grow strong and healthy.
• As the plant matures on the fertile land, it develops vibrant flowers rich in nectar and pollen.
• Bees are attracted to these flowers for their nectar, which they use to create honey, and in the process, they pollinate the plant, contributing to its reproductive cycle and the growth of new plants.
• This illustrates a symbiotic relationship, where bees and plants rely on each other for survival and growth.
• Despite their profound importance for the food we eat, bee populations are declining at an alarming rate.
• Last winter, Canada had its largest honeybee colony loss in the past 20 years, with 46% of colonies perishing nationally.
• Global warming, pesticide use, habitat destruction, and air pollution all contribute to bee mortality.
• By understanding the vital role bees play in our ecosystem and food production, and making conscious choices to help, we can contribute to the conservation of bees and the vital services they provide.

Casa Cavassa, a refined Renaissance residence in the historic heart of Saluzzo, was transformed in the late 15th century by Marquis Michele Antonio di Saluzzo into an elegant urban palace blending medieval structure with Renaissance elegance. Today home to the Civic Museum Casa Cavassa, it preserves original frescoes, stuccoes, and period furnishings, offering a rare glimpse into the domestic life and artistic tastes of the noble elite in the Marquisate of Saluzzo. Its harmonious courtyard and richly decorated interiors reflect the cultural flourishing of this independent Piedmontese state before its absorption into the Duchy of Savoy.
A slow and gentle walk after having needles and cameras shoved into my spine, so took a look at the Great Stour at Godmersham near Chilham a few miles down the road. The rain has totally water-logged the flood plane around the Stour, lets face it, a few months ago when Phoebe and I walked the Stour Valley Way things were bad, now there is no more absorption capacity! The fields all along the River have become lakes, but this is what they are for, water-meadows.....
The rising of the Full "Hunter's Moon" of October 9, 2022, with the Moon reflected in the calm waters this night at Crawling Lake Reservoir in southern Alberta. The Moon appeared very pink as it rose into the clear sky near the horizo, then turned more yellow as it rose into scattered bands of cloud.
This is a blend of 10 images taken 3 minutes apart with the RF70-200mm lens at 200mm and Canon R5, each frame exposed for the Moon. The frames were blended onto the first image (which contributes the lowest Moon and all the sky and foreground) in Photoshop using a Normal blend mode but with Blend If sliders and masks to isolate the later moons and reflected moons. A "Soft Pop" action for contrast enhancement added with TK 8 Actions panel, plus a mild Orton glow added with Luminar AI.
There is also a single-image version of this scene.
The thing I love most about being out shooting in places like this is the overwhelming feeling of being so small and insignificant. Self absorption is one of the most dangerous feelings one can have and anything that combats those feelings is healthy in my opinion. I'm not talking about confidence. That is a very valuable trait that we are should strive for. I'm talking about thinking you are the best thing going and that the world revolves around you. You see these people everywhere you go. They cut you off in traffic, hurt the people around them with their "it's all about me" attitude and are just not generally enjoyable people to be around. The lies that these people tell themselves turn to painful truth when they look in the mirror. The problem is that for some people, selfishness comes naturally and can be a difficult battle to fight. The feelings I get when I am out in nature really help, every time I'm out there, to realize that when compared to world around me, I am like a blade of grass in the wind. Sorry for the philosophic rant today. It's just the mood I'm in. :)

NGC 474 in the constellation of Pisces is a beautiful elliptical galaxy, well know for its tidal shells and stellar streams. Those tidal features have been well studied, but to date, it remains unclear what caused them. The stellar streams relate clearly to the absorption of smaller galaxies in the past.
NGC 474 spans about 250 000 light years and lies at a distance of 100 million light years.

The Milky Way shines brighter, when seen from higher altitudes. A miniature chapel (a roadside memorial) was built as a guardian for safe passage at the Baros Pass, the highest in Greece at 6,237 ft (1901 m). The chapel’s Cross is soaring in the skyline as a pictorial reminder of The Almighty; the Cross stands higher than the signposts telling the passers-by which earthly direction to go in…
The Milky Way lies diagnonally above the The Cross. Four hundred billion stars appear like the jewels of its heavenly crown. Yes, there are approximately 4×10¹¹ stars in our galaxy. It was captured with its galactic core visible (20.6° above horizon) during a chilly night (on July 12, 2021 at 23:10’ hrs, 14℃︎). At high altitudes there is less atmospheric absorption of the stars’ light prior to reaching the eye or the camera.
The first verse οf David’s Psalm 19 (Old Testament) was chosen to serve as the shot’s title:
“The heavens declare the glory of God; and the firmament sheweth his handywork.”

Excerpt from www.destinationontario.com/en-ca/attractions/algonquin-th...:
The first performance at the Algonquin Theatre took place on May 14, 2005 and was very warmly received by the community.
The Algonquin Theatre is located at 37 Main Street East in Huntsville.
Housed in Huntsville’s Civic Centre, it’s easy to spot the Algonquin Theatre. At the front of the theatre is a bronze statue of Tom Thomson, the wonderful Canadian painter. This statue was created by renowned and beloved Huntsville artist Brenda Wainman Goulet. The Little Free Library — an adorable collection of books available to the public — is a noticeable landmark beside the entrance of the theatre.
Besides theatrical productions, the Algonquin Theatre also hosts rock concerts, movie nights, tribute bands, comedy shows, live performances and even local elementary school productions.
Theatregoers love the wide, comfortable chairs and the eco-friendly lighting and state-of-the-art technology. Patrons and performers both appreciate the exceptional sound absorption, which improves the overall acoustic experience.
In 2018, Gord Downie used Algonquin Theatre’s space to secretly rehearse for his Secret Path tour. Other past performers at Algonquin Theatre include Ron Sexsmith, Jill Barber and Natalie MacMaster. Younger Canadian audiences will be delighted to know that Sharon and Bram (famous Canadian children’s musicians) have also graced the stage of the Algonquin Theatre.
This sparkling starfield, captured by the NASA/ESA Hubble Space Telescope’s Wide Field Camera 3 and Advanced Camera for Surveys, contains the globular cluster ESO 520-21 (also known as Palomar 6). A densely packed, roughly spherical collection of stars, it lies close to the centre of the Milky Way, where interstellar gas and dust absorb starlight and make observations more challenging.
This absorption by interstellar material affects some wavelengths of light more than others, changing the colours of astronomical objects and causing them to appear redder than they actually are. Astronomers call this process “reddening”, and it makes determining the properties of globular clusters close to the galactic centre — such as ESO 520-21 — particularly difficult.
ESO 520-21 lies in the constellation Ophiuchus, near the celestial equator. Ophiuchus was one of the 48 constellations which appeared in the writings of the second-century Egyptian astronomer Ptolemy, all of which are among the 88 constellations officially recognised by the International Astronomical Union today. Not all the constellations proposed by astronomers throughout history have survived, however — forgotten or obsolete constellations include Felis (the Cat), Rangifer (the Reindeer), and even Officina Typographica (the Printer’s Workshop).

DIET IN THE WILD: C. californica captures prey by extruding mesenterial filaments onto its prey which are used for digestion and absorption of food in the coelenteron. If the prey is too large to take into the coelenteron, the mesenterial filaments are used to digest it externally. They are carnivores consuming copepods, crustacean larvae and other zooplankton.
REPRODUCTION: Asexual by fission and budding resulting in a dense cluster of clones.
REMARKS: The presence of aggregations of C. californica increase the density of rock oysters and mussels by protecting them from predatory sea stars.

Snake found by our guide the morning we were leaving the reserve to board our bus for a three hour trip to the next location. Not the best image, but this one is the only youngster we saw of the boa.
An adult boa can be seen in the first comment section.

Sanzinia madagascariensis (also known as the Malagasy tree boa, or Madagascar tree boa is a non-venomous boa species endemic to the island of Madagascar. Two subspecies are currently recognized: S. m. madagascariensis and S. m. volontany.
Adults average 4–5 feet (122–152 cm) in length, although 6–7 foot (183–213 cm) specimens are not uncommon. Thermoreceptive pits are located between the labial scales. Females are larger than males. Endemic to Madagascar. Favors trees and shrubs near streams, rivers, ponds and swamps.
This species was classified as Vulnerable (VU) on the IUCN Red List of Threatened Species in 2006.
Arboreal and generally nocturnal, S. madagascariensis feeds on mammals and birds. Its thermoreceptive pits help it to locate its prey. It will also leave the trees to actively hunt for small mammals on the ground.
When females become gravid, their skin color darkens. This adaptation provides increased heat absorption for the developing young. After giving birth, the color returns to normal as soon as it next sheds its skin. Neonates are a bright red that may warn predators to "stay away", while simultaneously providing camouflage among brightly colored treetop flowers.
A 180° panorama of the classic arc of the auroral oval across the northern sky, shot at the Churchill Northern Studies Centre, Churchill, Manitoba, March 1, 2022. From this longitude the auroral oval is usually centred due north, as it is here.
Guests from the Learning Vacations aurora group are outside taking in the display, which was fairly weak this night, with this arc being almost the best it appeared. It shows the classic colours, with the main oxygen green topped by weaker oxygen reds. The arc turns more yellow toward the horizon due to atmospheric absorption.
Polaris is just left of centre at top, and marks due north. Capella is at top left; Vega is a right of centre above the trees; Arcturus is at far right. The Milky Way runs across the sky at left in the west. Wind chills were about -40° this night.
This is a 3-section panorama with the TTArtisan 11mm fish-eye lens at f/2.8 for 30 seconds each with the Canon R6 at ISO 1600. Stitched with PTGui.
Casa Cavassa, a refined Renaissance residence in the historic heart of Saluzzo, was transformed in the late 15th century by Marquis Michele Antonio di Saluzzo into an elegant urban palace blending medieval structure with Renaissance elegance. Today home to the Civic Museum Casa Cavassa, it preserves original frescoes, stuccoes, and period furnishings, offering a rare glimpse into the domestic life and artistic tastes of the noble elite in the Marquisate of Saluzzo. Its harmonious courtyard and richly decorated interiors reflect the cultural flourishing of this independent Piedmontese state before its absorption into the Duchy of Savoy.

Iron deficiency, or sideropenia, is the state in which a body lacks enough iron to supply its needs. Iron is present in all cells in the human body and has several vital functions, such as carrying oxygen to the tissues from the lungs as a key component of the hemoglobin protein, acting as a transport medium for electrons within the cells in the form of cytochromes, and facilitating oxygen enzyme reactions in various tissues. Too little iron can interfere with these vital functions and lead to morbidity and death.[1]
Total body iron averages approximately 3.8 g in men and 2.3 g in women. In blood plasma, iron is carried tightly bound to the protein transferrin. There are several mechanisms that control iron metabolism and safeguard against iron deficiency. The main regulatory mechanism is situated in the gastrointestinal tract. The majority of iron absorption occurs in the duodenum, the first section of the small intestine. A number of dietary factors may affect iron absorption. When loss of iron is not sufficiently compensated by intake of iron from the diet, a state of iron deficiency develops over time. When this state is uncorrected, it leads to iron-deficiency anemia, a common type of anemia.[1] Before anemia occurs, the medical condition of iron deficiency without anemia is called latent iron deficiency (LID).
Anemia is a condition characterized by inadequate red blood cells (erythrocytes) or hemoglobin. When the body lacks sufficient amounts of iron, production of the protein hemoglobin is reduced. Hemoglobin binds to oxygen, enabling red blood cells to supply oxygenated blood throughout the body. Women of child-bearing age,[2] children, and people with poor diet are most susceptible to the disease. Most cases of iron-deficiency anemia are mild, but if not treated can cause problems like an irregular heartbeat, pregnancy complications, and delayed growth in infants and children that could affect their cognitive development and their behavior.[3]

Six years after absorption into the Union Pacific system, nothing but MoPac blue and screamin' eagles can be seen in this view of a transfer run arriving in downtown St. Louis.
The rising of the nearly Full Moon, the Harvest Moon of 2020, on September 30, from a site near home in Alberta, looking just south of due east this night. Refraction distorts the disk and atmospheric absorption reddens the disk toward the horizon.
This is a multiple exposure composite of 6 images with the Canon 6D MkII through the 80mm A&M apo refractor at f/6 without field flattener. Taken as part of a time-lapse sequence with images every 2 seconds. The frames for this blend were taken 2 minutes apart, so selected from every 60 frames out of the sequence. All were at 1/8 second at ISO 100. Images stacked in Photoshop and blended with Lighten mode. The ground comes from the first image.
I was trying to compose some "copper screw"-like picture of the setting Moon by capturing it 105 times in every ten seconds. I slightly underestimated the atmospheric absorption so that the final lunar crescents are barely visible here. During the 20 minutes I had to reallign my camera four times.

Special:
- The Mini (ADO15) was designed by Sir Alec Issigonis (who also designed the Morris Minor over 10 years earlier) and is generally considered one of the most important milestones in automotive history.
- Based on the 2-door Mini John Cooper (racecar constructor of Formula 500, Formula 3 and Formula 1 cars and a friend of Sir Alec Issigonis) developed a sporty model: the Mini Cooper.
- In Italy in the years 60-70 it often was too expensive, due to high import duties, to purchase an imported car, so that most Italians opted for an Italian car. BMC England signed an agreement with Innocenti Milan (famous for the production of Lambretta) and from 1965 Innocenti was allowed to built the Mini 850 for the Italian market. Since 1971, the Mini Cooper was also built under license.
- It is equipped with a unique "Hydrolastic" shock absorption system, invented by famous British rubber engineer Alex Moulton, in which the various fluid-filled shock absorbers, by means of conduits, are in communication with each other.
- The Innocenti was faster and more luxurious (interior with more accessories and better finished) than the British Mini and nowadays very popular in the USA, Canada and Europe.
- Many details of internal and external were produced by Italian brands (IPRA for the radiators, Carello and Altissimo for the headlights), so especially for the Innocenti Mini Cooper 1300 spare parts are hard to find.
