These 9 images are illustrations of the principal Fraunhofer absorption lines in the solar spectrum. The data were taken as part of a programme to study the effect on the solar spectrum of a transit of the Earth across the solar disk as seen from the Moon during a lunar eclipse: to be published by Fei Yan et al. (2015, in prep.)
The spectra were obtained using HARPS (High Accuracy Radial velocity Planet Searcher) on the ESO 3.6m telescope at La Silla in Chile on the night of the 15 April 2014. This is the equipment that has been used to find many of the known exoplanets that have been discovered by exploiting the 'wobble' induced in the parent star's radial velocity by an orbiting planet or planets. The spectrometer produces one sample of the spectrum each hundredth of an Ångstrom (a thousand samples per nm). See: www.eso.org/sci/facilities/lasilla/instruments/harps.html
for details.
The data plotted here are from just one of the 382 spectra obtained on that night by pointing the telescope at the Tycho crater on the Moon to look at the reflected light in the umbral and the penumbral shadow of the Earth and, for this spectrum, the fully illuminated Moon. It has been used to extract high resolution spectra of the principal Fraunhofer absorption lines from the telluric molecular oxygen B-band in the far-red to the L-line from atomic iron in the ultraviolet.
The Mg I b triplet is a strong absorption in the solar spectrum and can be seen clearly by eye with a small pocket spectroscope. This transition, from 3p 3P0 - 4s 3S, is not a resonance line like the Na I D and Ca II H & K lines. However, the lower level has no allowed transition to the ground state, 3s2 1S, and so it can build up to a significant level of occupation, allowing absorption to occur. There is an analogous triplet absorption in the ultraviolet, 3p 3P0 - 3d 3D, at at 3838.3, 3832.3 and 3829.4 which is also strong.

Here's the How-to:
1) Prewash your fabric to remove any manufacturers' finishes that might prevent proper dye absorption. You're gonna want to iron it after for a nice smooth surface to work on.
2) Very lightly sketch out a basic composition. I used a light pencil mark that could be washed out. Vanishing fabric markers would be ideal for this purpose.
3) Fill the metal-tipped applicator bottle with Batik EZ resist and start drawing. Let dry fully. You can use a hair dryer if you're in a hurry.
4) Grab your rubber gloves and cover your work surface with plastic.
5) Place fabric on sheets of plastic wrap that has been overlapped so plastic is slightly larger than fabric.
6) Shake Rit Black liquid dye and measure out 1 Tbsp into 1 Cup of very hot 140° water and mix. Paint dye evenly across the fabric panel letting it soak well into the fabric.
Note: I was creating a grey tone with the black dye so I used a weaker dye recipe. If I was going for a pure black color, I would have doubled the amount of dye.
7) Place a layer of plastic wrap over top and seal the edges.
8) Cover bottom of microwave with paper towels. Place plastic-wrapped fabric in microwave. Set on High for 2 minutes. Wearing rubber gloves, remove from microwave. Cut open plastic wrap. Allow fabric and wrap to cool.
9) Rinse under cool running water until water runs clear. Wash in warm water with mild detergent, rinse and dry.

LEVELS OF ABSORPTION, 2004 by LAURA MAYOTTE

Handmade flax paper, handspun and dyed linen yarn, indigo dye.
Artist’s Statement
Levels of Absorption holds many meanings for me. Literal meanings, such as the actual absorption of the indigo dye on the pages and watermarks, and abstract meanings, such as (being a book form) how much knowledge we absorb over a lifetime, the fact that we never make use of our entire brain, that there is always room for more knowledge, learning and growth, and that also the tree-like shape adds to this idea of growth over time. All the sewing reflects the pathways of the brain and how we think; how everything is connected, how odd things can remind us of seemingly unrelated things, but they are all there and accessible. This sewing is also rather electricity-like in appearance, and metaphorically, referring to how fast our thoughts can be, our natural reflexes or responses to stimuli, and how knowledge gained over time can be instantly accessed once learned.
'THE RAILWAY STATION' (1862) is set in the crowded and busy Paddington railway station in London. Frith was not only thoroughly modern and commercial in its exhibition – it wasn’t shown at the Royal Academy, but in a private gallery which charged one shilling (£0.05) per visit – but he used photographs in its execution. It’s rich with little social vignettes, and among its many faces are associates and friends of the artist, including the dealer who paid for it.
Paddington Station, completed a decade earlier, had been built by the great Victorian engineer Isambard Kingdom Brunel. It was a cutting-edge building, constructed from cast iron and glass and lit by gaslight. It was the London terminus of the Great Western Railway, with trains running to Bristol, Cardiff, Exeter, Plymouth and the West Country.
The scene shown takes place on the platform, where a large and disparate group of people are assembled preparing to board the train.
At the left, Frith shows one of the early steam locomotives, with its open cab and pile of coal. A railway porter is pushing a large barrow piled high with trunks and boxes to be loaded onto the train. Above them are the cast iron arches of its vaulted glass roof, from which thoroughly modern gaslights are suspended.
In the foreground is a group consisting of Frith and his family, with his wife kissing the couple’s younger son goodbye (at the left of this detail). The boy clutches a cricket bat so is presumably off to school for the summer term. Frith and his elder son stand behind. Beside them is a bearded man in a fur coat, modelled on a refugee Venetian nobleman, who had given lessons in Italian to Frith’s daughters. He is arguing over his cab fare. Then comes a bride, bridegroom and two bridesmaids.
Behind them more porters are stowing luggage on the roof of a carriage, where it will be covered by a heavy tarpaulin for the journey.
The centre of action is at the right of the painting, where an arrest is being made. A man dressed in brown clothes is about to board the train, within which a woman stares aghast at the scene. Two Scotland Yard detectives, complete with top hats, are in the process of serving him a warrant for his arrest, the other stood ready with a pair of handcuffs. At the far right is the train’s guard, who is holding the carriage door open.
The policemen were modelled by the artists John Brett and Benjamin Robert Haydon, who were re-enacting a well-known story at the time. We don’t know what event has preceded or precipitated this arrest, nor do we have any inkling as to whether the alleged criminal will try to run off, or be taken into custody. Much as in later ‘problem pictures’, the viewer is left to endless speculation and absorption.

Adox Scala 50 film in négative processing:
After testing the high-resolution and ultra-fine gain film Adox HR-50 processed with the fine-grain developer Adox Atomal 49, I would like to compare with the Adox Scala 50 that likely the same formula but commercially intended to be processed with a reversal chemistry. I tried this chemistry past year but, unfortunately the bleaching bath was degraded and I obtained incompletely bleached positives that I reported here: flic.kr/s/aHBqjBCCha. The Scala 50 could be however processed as a normal negative using the same processing times and developer as recommended by Adox for HR-50.
For testing Scala 50 as a negative, I picked up for a second time my newly arrived exceptional French 35mm camera FOCA Universel RC (see below for details about this rare and fascinating camera), I went for photowalk at Port Rambaud, along.the Saône river bank, Lyon, France. The weather was very fair with gentle clouds in a nice blue Skye with a mild outdoor temperature (28°C).
I mounted on my FOCA the OPLAREX lens 1:1.9 f=5cm equipped with a yellow filter FOCA x2.5. The OPLAR /OPLAREX lenses for the FOCA’s only accept push-on filter (42.5mm in this specific case). A vintage Genaco cylindric stainless-steel shade hood conceived for a 5cm focal length was also used all along the session.
Expositions were determined for 32 ISO to compensate the absorption of the yellow filter (not the x2.5 coefficient due to the enhanced sensitivity of the film in the yellow). Metering was achieved using a Minolta Autometer III lightmeter fitted with a 10° finder for selective metering privileging the shadow areas, but too much to avoid high-lights saturation, or also in the incident-light mode with the integrating opal dome of the Autometer.
Most of the views were taken at 1/50s to 1/200s and f/5.6 to f/9 apertures.
Port Rambaud - La Confluence***, July 31, 2025
69002 Lyon
France
_____________________
*** Port Rambaud is a former river port in Lyon, on the Saône, located in the Confluence district at the end of the peninsula between the Saône and Rhône rivers up to the Pont de la Mulatière. The construction of the port was decided in 1909 but work was frozen during the First World War and only completed in 1926. Initially 500 m long, it was first extended in 1929 to the Pont de la Mulatière, reaching 1,000 m in 1953, allowing 16,000 m3 of hydrocarbons to be stored. From 1985, the activities of the Rambaud port were transferred to the new Édouard-Herriot port on the Rhône and the Rambaut port was closed in 1991. The old port became a concerted development zone to create the new "La Confluence" district where post-modernist architectural projects.
In 2014 was opened the Musée des Confluences (French pronunciation: [myze de kɔ̃flyɑ̃s]) a science centre and anthropology museum l ocated at the southern tip of the Presqu'île at the confluence of the Rhône and the Saône, adjacent to the A7 highway Paris-Marseille. The museum was designed in the deconstructivist architectural style, said to resemble a floating crystal cloud of stainless steel and glass, and was created by the Austrian firm Coop Himmelb(l)au.
______________________
After completion at view Nr. 38, the film was rewound normally and processed using 400 mL of stock solution of Adox Atomal 49 developer for 8min30 at 20°C.
Digitizing was made using a Sony A7 camera (ILCE-7, 24MP) fitted to a Minolta Auto Bellows III with the Minolta slide duplication accessory and Minolta Macro Bellow lens 1:3.5 f=50mm. The diffuse light source was a LED panel CineStill Cine-lite.
The RAW files obtained were inverted within the latest version available of Adobe Lightroom Classic (version 14.4) and edited to the final jpeg pictures without intermediate file. They are presented either as printer files with a frame or the full size JPEG's together with some documentary smartphone color pictures.
About the camera and its history :
Among the French 35mm camera produced by « Optique & Précision de Levallois S.A. » from 1945 to the middle of the 60’s, the FOCA Universel « RC » is likely the most captivating ever produced in France at that time.
The camera was the last development of the FOCA, sometime called the « French Leica » because the optical and mechanical precision matched and even surpassed the original thread-mount Leica. Far before the first Leica M (the M3 in 1954) O.P.L. developed a bayonet-mount FOCA in 1948 called the FOCA « Universel ». Seeing the incredible viewer and range finder of the Leica M that is likely the most sophisticated system even engineered, O.P.L. released lately a great improvement of the FOCA with a novel collimated, parallax auto-corrected, of a fully original and different design of the Leitz system.
The FOCA Universel RC It is a rare camera that only appears for time to time on the collector market, being only produced to a bit more than 2000 overall units in the years 1962 and 1963, just before O.P.L. decided to quit the camera production and returned to other instrumental optical production. O.P.L. soon merged with SOM Berthiot and today can be found still in the industrial filiation of SAFRAN group, the French leader company for designing and producing system for aerospace appliances. The plant where the FOCA's were produced still exists in an almost original form in Châteaudun, Eure-et-Loir, France.
I got my first FOCA URC unit two years ago (Sept. 2023, flic.kr/s/aHBqjAV6Dg) that is a standing and emotional piece of my small camera collection.
I got this one from an apparently ignored auction on the French eBay. We were only two biders in the last 5s and I won the auction not far away to the initial price. The camera was fully revised, with new shutter curtains, a new delayed shutter release mechanism. The serial number indicated a year-1962 production starting with 1.000.000, closed to my first FOCA URC. The camera works in every functions like on its Day-1! The camera came with a late version 1962 of the OPLAR 1:2.8 f=5cm standard collapsible lens of excellent quality, the FOCA UCR dedicated ever-ready leather bag with the original leather neck strap in good condition.
The original O.P.L. camera warranty and a registration postal card fortunately followed the life of the camera, indicating that this beautiful FOCA Universel RC was sold to its first owner on August 9, 1963 by the official FOCA dealer « ROYAL-PHOTO, Photo-Ciné-Magnétohone », 42, rue Vignon, Paris 9ème arrondissement, France, today a Weill fashion shop at the same address. The address of the owner also still exists with the original Parisian building in place, Boulevard Poniatwski, next to the Métro station « Porte de Charenton », Paris 12ème arrondissement.
The shown original FOCAL Universel RC user manual is the one that came with my other FOCA URC camera.
These information pushed me to question what were the news in France on this Friday, August 9, 1963… France was mainly on vacation, by an exceptional wet and fresh weather that wasted many French citizens holidays. The whole national radio information bulletin is still available online here :

LDN 1613, also known as the Cone Nebula, is a dark absorption nebula in the constellation Monoceros. It consists of a dense cloud of dust and cold molecular gas projected against a brighter emission nebula in the background. This is why, in images, it appears as a dark cone rising from the red glow of hydrogen.
This region is part of the extensive NGC 2264 complex, which also includes the Christmas Tree Cluster, the Fox Fur Nebula, and young star-forming regions. The Cone Nebula itself was discovered by William Herschel on December 26, 1785, and catalogued as H V.27. The designation LDN 1613 comes much later, from Beverly T. Lynds’ 1962 catalogue of dark nebulae, compiled from photographic plates of the Palomar Observatory Sky Survey.
The nebula lies approximately 2,500 to 2,700 light-years from Earth. The dark pillar itself is about 7 light-years long, while the broader NGC 2264 complex covers a much larger area of the sky.
What is particularly interesting is that the cone shape is not accidental. It is formed by the intense radiation and stellar winds from young, hot stars, which gradually blow away and erode the surrounding gas. Denser parts of the cloud resist this process for longer and form dark pillars similar to the famous Pillars of Creation in the Eagle Nebula. Inside such regions, new stars — and later even planetary systems — may be born.
In the image, the contrast between the red light of ionized hydrogen, the dark dust structures, and the bluish reflection regions, where dust reflects the light of young stars, stands out very clearly. The result is a striking example of how young stars are not only born from nebulae, but also gradually reshape them with their radiation.
I started imaging this winter-sky object well into the spring season because I wanted to test the Sloan i′ filter on a suitable target. Although the conditions were no longer ideal, I still managed to collect at least some data — and this is what emerged from it.

A Fomapan Action 400 black-and-white film to test the effect a the special Foca filter "Dyma" produced in France in the 50's.
The filter is called "Dyma" due to the presence of neodymium in the glass giving an unusual absorption by bands in the visible spectrum. In particulier blue and yellow color ans more absorbed than the rest of the spectrum. The filter existed in two different versions with the coefficient x2.5 or 3.5. Here the 42mm push-on Foca Dyma filter used is a x 3.5.
As a consequence, I exposed the Foma 400 for 80 ISO using a Minolta Autometer III with a 10° finder for selective measurements privileging the shadow areas. I used my FOCA camera PF2B year 1956 and its normal Oplar lens1:2.8 f=5cm equipped for all the views with the Dyma filter and a Genaco metal shade hood.
Typical settings during the session : 1/100s f/8 to f/11.

After exposure, the film was processed using Adox Adonal (Agfa Rodinal) developer at dilution 1+25, 20°C for 6 min.
The film was then digitalized using a Sony A7 body adapted to a Minolta Auto Bellows III and a Minolta Slide Duplicator using a lens Minolta Bellow Macro Rokkor 50mm f/3.5 at a reproduction ratio of 1:1. The reproduced RAW files obtained were processed in LR prior the the final JPEG editions.
All views of the film are presented in the dedicated album either in the printed framed versions and unframed full-size jpeg.
About the camera and the lens:
The Foca type PF2B (PF for "Petit Format") was constructed in France by the company "Optique & Precision de Levallois" (OPL) starting from 1947. It was manufactured in the Chateaudun OPL factory, route de Jallans, France, in 1956 among a late series of the PF2B. The factory, constructed in 1938, is still at the same place under the name of SAFRAN now producing precision devices for aerospace appliances.
The camera is equipped with the collapsible OPLAR lens (a Tessar formula) 1:2.8 f=5cm. The focal shutter of the PF2B has timing of 1/1000, 1/500, 1/200, 1/100, 1/50 and 1/25s plus the B pose. A slow exposure device below 1/25s could be installed by the aftermarket service and was installed basically for the FOCA PF3 and Foca Universel.

Images and spectra of a flat plate crystal of titanite (sphene) with a maximum dimension of 17mm. These are quite difficult spectra to obtain since the absorption lines seen in transmission (orange line) are very weak and the fluorescence (purple line) is very faint.
The absorption lines between 730 and 830 nm are due to neodymium (Nd^3+) while the line at 972nm is due to samarium (Sm^3+).
The strongest fluorescent emission lines are due to Sm^3+ with others possibly due to europium (Eu^3+) and chromium.(Cr^3+)
The two images at the bottom are of opposite sides of the plate crystal and taken with a linear polariser at an angle that minimises the transmission and deepens the colour.

Tiles or metal roofs? If you have larger budget you can decide to install tiles or metal roof. Tiles have very low absorption and very high strenght that provides higher resistance to mildew and staining caused by environmental factors.
Metal roof is the most expensive choice but it is also the most durable and trouble free available roof today. f today.

Sheepskin contains lanolin, a natural substance, which soothes the horse's sensitive or inflamed skin. When sheepskin is set directly against the animal's body, it stimulates blood circulation and promotes a therapeutic effect.
- "Open-channel" design alleviates excessive pressure from the horse's spine and promotes increased air circulation.
- Two large pockets are designed specifically to ensure proper fit of the saddle and comfort for the horse by accommodating both specialized and custom-made shims.
- High Resiliency open-cell foam shims (included in the package) allow for the overall weight to be redistributed over a larger area, thus minimizing pressure points.
- Breathable 3-Dimensional Spacer fabric reduces heat build-up and provides excellent moisture vapor transfer.
- The Non-Slip mesh upper assures perfect grip and steadily secures the ComfortLUX Half-Pad under the saddle.

hortaleza, madrid
the uva (neighbourhood absorption unit) de hortaleza was built as temporary housing for displaced chabolistas (shanty town dwellers) by the government in 1963. they were provisionally planned to be used for 5 years. 45 years later just under half of them are still in existence with approxinmately 460 families still living there. they are totally deteriorated due to their cheap construction and lack of maintenance. presently the future of the uva is being decided upon in the courts.

David Oyediran is looking at microwave absorption properties of nanomaterials in the Advanced Sensors Development Laboratory.
Erin Beckman is a Dean’s Honored Graduate in the Departments of Mathematics and Chemistry and Biochemistry. She is graduating with honors degrees from both departments. Lindsay is being recognized for her excellent academic performance and research efforts working in collaboration with Professor John Stanton in chemistry and Lorenzo Sadun in mathematics that have culminated in an honors thesis, “Equilibrium and Non-Equilibrium Molecular Absorption: A study of the Ising model and the infinite parking limit problem.”
Erin began her research career in the FRI lab of Drs. Jones and Holliday, synthesizing polymerizable lanthanide complexes. After this, she joined Professor Stanton’s research group, studying models of chemical absorption onto surfaces. She enrolled in a Discrete Mathematics class with Professor Michael Starbird as a sophomore, and as a junior and a senior she quickly took on an additional mathematics major. It turns out that the mathematics behind chemical phenomena is surprisingly deep and requires an understanding of statistical mechanics (in her case, the Ising model of ferromagnetism), which in turn is built on the statistical study of random partitions, among other topics. As it happens, the rudiments of these ideas are presented in a Discrete Mathematics class, but the gulf is huge between that class, which she had just taken a couple of semesters earlier, and the research tools she needed for her project. Erin made remarkable progress in just a couple of semesters, and did so mostly on her own, chasing chains of references to understand the principles involved.
In addition to being a part of the Dean’s Scholars Honors Program, Erin demonstrated her excellence in many ways while at UT. She was a math and chemistry tutor at the UT Sanger Learning Center for four years. She also made the time to study abroad at Trinity College in Dublin, Ireland; in addition to exploring Ireland and Europe, she worked there in a marine biology lab and studied ancient languages like FORTRAN. She is known as an avid soccer player and took a fencing class as well. Not surprisingly, she has received a number of accolades while at UT, including being on the honor roll for three years running, winning a CNS Book Award, as well as the Dow Chemical USA Centennial Endowed Scholarship, the Chemistry and Biochemistry Authors’ Scholarship, and the American Airlines Global Leaders Travel Scholarship.
Next year, Erin plans to pursue a PhD in mathematics at Duke University, where she plans to study mathematical biology. Among the books she has chosen for her summer reading are The Power of Habit: Why We Do What We Do in Life and Business by Charles Duhigg, The Five Elements of Effective Thinking by Michael Starbird and Edward Burger, Mavericks, Miracles, and Medicine: Pioneers Who Risked Their Lives to Bring Medicine into the Modern Age by Julie M. Fenster, and Introductory Complex Analysis by Richard A. Silverman.

AirDrain Synthetic Turf Drainage Doubles as a Drainage Layer and Shock Pad
Benefits of AirField in a green roofing system include:
AirDrain creates and helps maintain a constant Gmax for artificial turf (See below)
Thickness and resin consistency of AirDrain provides uniform shock absorbency
Shock absorption reduces the strain on joints and ligaments
AirDrain is only limited by the drainage capacity of the profile above it
Installation time measured in days instead of weeks
AirDrain can be reused when the artificial turf must be replaced
Water harvesting reclamation and reuse
Helps qualify for LEED and other green building credits
A smaller carbon and development footprint with reduced site disturbance
100% vertical drainage under the entire field surface
Minimizes water related injuries / Less infill migration due to superior drainage
AirDrain is a 100% recycled product
Less infill migration due to superior drainage

The tests were performed using a Triax 2000 A-1 Missile, tripod mounted Gmax registration unit(www.triax2000.com). This report presents background information on the test procedures, existing conditions, test results and observations in football, baseball, softball, soccer, lacrosse, and field hockey artificial sports fields.
The environmental impact of a green roof is undenyable, and adds significantly to the LEED Point system designed by the USGC in all five major areas: sustainable site development, water savings, energy efficiency, materials selection, and indoor environmental quality. Green roofing replaces the green space displaced by a building, prevents excess stormwater drainage, reduces the temperature of a building and the urban heat island effect, protects and extends the useful life of a roof, and reduce energy demands. What's more, a green roof incorporating AirDrain means your design includes renewable, recycled, and locally obtained materials. We know you have a choice in designing a green roof, and we hope you consider the many benefits of AirDrain.
