This is a close-up of the acoustical absorption walls of the BP Hall at the Disney Concert Hall in LA. The whole structure, inside and out, is a architectural masterpiece.

 

My father and I took a (free!) self-guided tour that was amazing. I definitely have to return to photograph the whole grounds a bit more thoroughly.

Two uses of sodium humate

 

●Animals feed additive: Sodium huamte forms a kind of protecting film on the mucosa cells of the intestine. This protection reduces the absorption of toxic substances, as they may occur as a follow-up from infectious processes or from residues from animal feed in the intestinal tract.

It also has the distinct property to absorb toxins from proteins, toxic residues and various heavy metals. Stabilize of intestinal flora. Fix micro-organisms, toxins and harmful substances in animal feed. Promote growth and stimulate the immune system. (#Chickens, #geese, #ducks ,#turkeys,#cows ,#fish, #dogs ,#cat,#horses #shrimp #crabs ...)

 

●Industry use: sodium humate can be used for removing toxic metals and their ions from wastewater. Sodium humate can be applied as an adjunct in dissolved air flotation cells to assist in the removal of trace amounts of grease, oil, liquid organics and suspended matter. They should be considered as a special coagulant aid to be used in conjunction with water soluble polymeric flocculants for removal of soluble organics. They can also be used as potential fluid loss additives in certain types of organic liquids to prevent seepage from lagoons or pit containment areas.

-Absorption- This name was given thinking of black! Black is the absence of color as well as the combination of all! It can be mysterious, sexy, and sophisticated; it has this special quality of being simultaneously negative and positive! A color of mourning and at the same time of rebellion! That is how it came!

 

This nuno-felted scarf consists of a polyester fabric, commonly Trevira, in black colour and extra-fine Australian merino wool in a punch of colours; yellow, orange, red, turquoise, black! The black polyester fabric is used as a basis for the scarf and the wool is applied on the top in order to create the patterning. It is created with the wet felting technique. The distinction between this nuno-felted scarf and a simple felted item is that it contains also a different material except from wool, i.e. polyester fabric. The scarf measures approximately 95 cm (37.4 in) length and 95 cm (37.4 in) width.

 

The combination of wool in thin layers and other thin and smooth materials such as silk, and in this case Trevira, gives a very light and airy; sometimes even sheer fabric!

 

Long Exposure taken at Uttakleiv Beach (Norway).

The emission/absorption features at 645 and 685nm in the transmission spectrum (green line) are Cr3+ Fano resonances. The longer wavelength feature appears as R-line fluorescence in the red line spectrum. Note the logarithmic y-axis which makes these features clearer.

 

This cut chrome diopside sample from Siberia is dark in colour and is 12mm long. It was obtained from Dr Jaroslav Hyršl.

 

The fluorescence peak around 515nm could be due to surface contamination - I need to check this.

Commissioned tapestry for Albert Sherman Center, University of Massachusetts. 4' x 7' x 4". 2015. One of three pieces commissioned for the research center. All three of these pieces reflect on the beauty and mystery in the biological world unseen by our naked eyes. The microscopic world of our bodies can seem remote and make us feel a bit squeamish, so by carefully hand stitching a window onto this world in the warm and comforting medium of quilted textiles, I hope to make this realm more intimate, accessible, tactile, and yet, still mysterious.

 

This piece was inspired by a slide mount of rabbit intestines.

Wetlands are biodiversity rich sensitive ecosystems that harbor hundreds of plants, insects, birds and other animals uniquely adapted to their wetland mode of life.They are crucial to maintain the regional water balance through ground water recharge and absorption of flood waters and also serve as the rice bowl of developing countries. Nevertheless, wetlands play immense role in the socio-economic and livelihood aspects of local communities living around the wetland. In India, rural communities depend wetland for livelihood through farming, mat making etc; for food through fishing and hunting; for roof thatching by collection of reeds and palm leaf ; for firewood; for fodder etc. However, these wetlands are now under a threat of conversion for big industrial and real estate projects, change in lifestyle of local community, over extraction of resources by increased population, pollution,waste dumping, eutrophication and pesticide farming. There are three important wetlands in the Puducherry region namely Oussudu, Bahour and Kaliveli that provide important resources for local communities and also are a home to tens of thousands of migratory birds that visit the Puducherry region in winter. These wetlands have been acknowledged as Important Bird Areas(IBAs) by IBCN, since many of these birds are represented in more than 1% of their global population.

 

The recent threat on wetlands of Puducherry is more due to the change in life style of local community living around these wetlands. The younger generation is not much dependent on wetland resources, The younger and modern generation has lost the compassion and bonding to the wetland which their forefathers maintained through sustainable livelihood practices. This has resulted in a change in attitude and perception of the community towards unsustainable farming and resource extraction, game hunting, intensive fishing and reclamation, ultimately resulting in shrinking of wetland area and loss of biodiversity at an alarming pace. Local community is leaving the traditional farming practices for more fertilizer and pesticide based farming; fish stock is depleted using invasive Gill nets. Since Puducherry is fast developing region with rapidly growing commercial tourism and industrial establishments, these wetlands are under the threat of reclamation for resort construction and other commercial establishments. Poaching for a sport as well as open selling of birds including the threatened species is common. School drop-out are noticed to get attracted to such practices to make easy money as well as hunting for a sport with peers. With time, they may grow into expert hunters who will depend on poaching as the main source of income for the family. There are many wetland awareness programs organized by Forest Department as well as NGOs targeting school kids and educated community through workshops. School drop-outs are often not specially targeted by any of such programs and often not brought under the ambit of such programs. This gap needs to be addressed for local conservation efforts to be fully effective. We have chosen birds as the umbrella species whose conservation will in turn protect the lake and biodiversity as a whole. Birds are attractive and beautiful; ,which may easily get compassion from drop-out kids if guided appropriately. With proper efforts, the poachers can be turned to protectors and expert tour guides to facilitate ecotourism.

Following a recent post on purple fluorite, I have measured both the fluorite and the irradiated halite using a reflectance probe that increases the effective transmission pathlength within the crystals. I have also added a UV measurement of the fluorite. These spectra show more structure than the earlier ones.

 

The colloids are responsible for the broad absorption bands in fluorite (at 560nm) and halite (at ~620nm). I am uncertain, however, of the cause of the absorption band around 400nm that both of these crystals show.

 

I think it is unlikely that the 400nm band results from a divalent rare earth element (REE) as has been suggested for other fluorites. Is it due to a colour (F-) centre in the crystals?

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.

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.

You may need an iron supplement to replace iron from blood loss. To enhance absorption, take iron

supplements with water or juice on an empty stomach. If nausea or constipation are problems, take iron supplements with food. Absorption may be decreased by as much as 50 percent when taken with a meal or a snack. A woman who's pregnant or breast-feeding. You need more of some nutrients, especially folate and iron-and perhaps calcium if you don't consume enough calcium-rich foods. Check the label's Supplement Facts to make sure you get enough for a healthy pregnancy. Ask about a prenatal vitamin/mineral supplement.

A red giant whose spectrum is dominated by strong absorption bands of carbon-containing molecules. The Swan bands of C2 are especially prominent, with absorption by CN, CH, C3, SiC2, and C aII present to varying degrees, with often a strong sodium D line.

 

Carbon stars, also known as C stars, have carbon/oxygen ratios that are typically four to five times higher than those of normal red giants and show little trace of the light metal oxide bands that are the usual red giant hallmark. They resemble S stars in their relative proportion of heavy and light metals, but contain far more carbon in their upper layers. The carbon is likely the dredged-up ashes of nuclear helium burning in the stellar interior. Carbon stars lose a significant fraction of their total mass in the form of a stellar wind which ultimately enriches the interstellar medium – the source of material for future generations of stars.

 

Carbon stars were previously classified as stars of spectral type R (hotter, with surface temperatures of 4,000 to 5,000 K) and N (up to 10 times more luminous but cooler, with a temperature of about 3,000 K). They are typically associated with some circumstellar material in the form of sooty shells, disks, or clouds.
