The reaction is catalyzed by strong acids, weak acids, organic acids and also by Lewis acids. The composition of terpolymers has been determined by elemental analysis and spectral studies such as UV, IR and NMR have been carried out to elucidate the structure of the terpolymers. The polymer exhibit high temperature resistance better thermal properties as evident from the TGA data. The polymer undergo degradation under inert atmosphere at increasing temperature provides good for nature. Spectroscopic data revels that long chain polymer hold together not only by C-C bond, but also the electrons are delocalized in conjugation showing coloured aniline- formaldehyde-α-naphthol terpolymers.

'An Aquired Taste'
The ninth annual short story competition The Mogford Prize for Food & Drink Writing 2021 ‘An Aquired Taste’ by Emma Teichmann Short List Runner Up ‘An Acquired Taste’ It usually falls under cosmetic surgery, in which case the Public Health Service won’t cover it and you have to fork out for private care, but as I’d lost mine in a road accident they said the procedure would be free – or, rather, at the expense of the tax payer. It seemed like a no-brainer. This was almost a year after the collision. When I was thrown from my motorbike, having clipped the side of a dairy truck as I came round a corner just a little too fast and wide, my immediate worries were the shattered pelvis, ruptured spleen and brain bleed, my skull partially caving in when my helmet cracked like an egg against the concrete. It was, I was told, a miracle I survived, though it didn’t feel that way as I lay in my hospital bed. I was nil by mouth the first week as I went in and out of theatre. My jaw and nose were also broken, and even when I was finally able to – slowly, cautiously – imbibe a liquid meal, it was only a sludge-green smoothie. It didn’t look like it should taste of anything, so I wasn’t surprised when it didn’t. ‘An Aquired Taste’ 1 As I got stronger and began to feel a semblance of my At first, I tried to make light of it. Dining with friends, I normal self, I would stop a passing nurse to ask, “What’s for raised my glass of water and said, “Hey, now I can turn water dinner?” When she said, “Still smoothies, I’m afraid” I’d into wine.” They laughed a little too loudly at my feeble groan, “Not again! Let me have a proper meal,” singing after attempt at a joke. -

Find Out if You're a Supertaster! Young Scientist Program Anatomy & Physiology Teaching Team Adapted from sciencebuddies.org Katherine M. Holzem Last Modified 10.10.12 Abstract Are you really picky about food? Or do you know someone who is? It might be because he or she is a supertaster! To supertasters, the flavors of foods are much stronger than to average tasters. Are you a supertaster? Find out with this tongue-based science fair project! Objective Determine what percentage of the population are supertasters, average tasters, and non-tasters. Terms and Concepts • Taste bud • Receptor • Supertaster • Non-taster • Average taster • Papillae Introduction Do you hate the taste of broccoli? Or think that grapefruit is extremely bitter? If so, you may be able to blame it on your taste buds! Taste buds are sensory organs on your tongue that help you sense different flavors. Each taste bud is made up of about 150 cells, called receptors. Each receptor is best at sensing a single flavor: sweet, salty, bitter, or sour. The sum total of these sensations is the "taste" of the food. The number of taste buds varies from person to person. People who have more taste buds are called supertasters. To supertasters, foods have much stronger flavors, which often leads to supertasters having very strong likes and dislikes for different foods. Supertasters often report that foods like broccoli, cabbage, spinach, grapefruit, and coffee taste very bitter. The opposite of supertasters are non-tasters. Non-tasters have very few taste buds and to them, most food seems bland and unexciting. -

Contents 1. Introduction 2. Symmetry 3. Chirality 4. Stereogenicity 5. Conformation and configuration 6. Configuration descriptors 7. Dependence of the properties of chiral molecules on the enantiomeric composition 8. How to obtain stereoisomerically pure compounds Glossary Bibliography Biographical Sketch Summary The aim of this chapter is to provide the reader with the basic concepts necessary to deal with the stereochemical aspects of organic chemistry. As in any other interpretation of stereochemistry that aspires to be rational, also in this one a detailed knowledge of the symmetry properties of a molecule and of the relationship between symmetry properties and molecular behavior at all levels is considered of fundamental importance. Another central point is the strict distinction between chirality and stereogenicity that underlines all the discussion both as an inspiring principle and guidance to the use of a correct stereochemical language. In addition to classic topics such as isomer classification, stereochemicalUNESCO descriptors, and conseque nces– ofEOLSS enantiomeric composition, a short presentation of the principal methods for obtaining enantiomerically pure compounds is included. 1. IntroductionSAMPLE CHAPTERS According to the Merriam-Webster Online Dictionary, stereochemistry is: "a branch of chemistry that deals with the spatial arrangement of atoms and groups in molecules". The Oxford Dictionary of English defines stereochemistry: "the branch of chemistry dealing with composition of matter as affected by relations of atoms in space". -
How To: Discover If You're a Super-Taster
Psych Lab BTST – BLUE TONGUE SUPER TASTER Procedure Be very careful with the food dye as it stains and check that you're not sensitive to its ingredients! 1. Place a cotton bud into your bottle of blue food dye until it is well coated. Stick your tongue out and, using a mirror for guidance, coat the front third of your tongue with the dye. 2. Next, carefully place a hole-punch reinforcer on to your tongue. You can stick two ring reinforcers together to help transfer it more smoothly. If you don't have any reinforcers you can use a hole-punch to create a hole in an index card. 3. The blue dye will stain the tongue but slide off the prominent pink bumps known as papillae. Each bump contains three to five taste buds. 4. Ask a friend to count how many pink bumps they can see on your tongue inside the ring reinforcer - try to keep your tongue still! They may find it easier using a magnifying glass. 5. Using your Chromebook or other device, take a photo of your tongue and zoom in on the image. Attach this to your Lab Report as proof of completion. 6. The chart below reveals how your sense of taste compares to the rest of the nation...Place a check mark in the table that best reflect your findings in the experiment, take a photo of your results and attach this to your Lab Report. Number of papillae Type of Taster How common in population Fewer than 15 Non-taster One in four 15 - 35 Average taster One in two More than 35 Super-taster One in four BBC Science - How to: discover if you're a super-taster SCIENCE How to: discover if you're a super-taster Are you a super-taster?

Faces of the League Portraits from the Permanent Collection
THE ART STUDENTS LEAGUE PRESENTS Faces of the League Portraits from the Permanent Collection Peggy Bacon Laurent Charcoal on paper, 16 ¾” x 13 ¾” Margaret Frances "Peggy" Bacon (b. 1895-d. 1987), an American artist specializing in illustration, painting, and writing. Born in Ridgefield, Connecticut, she began drawing as a toddler (around eighteen months), and by the age of 10 she was writing and illustrating her own books. Bacon studied at the Art Students League from 1915-1920, where her artistic talents truly blossomed under the tutelage of her teacher John Sloan. Artists Reginald Marsh and Alexander Brook (whom she would go on to marry) were part of her artistic circle during her time at the League. Bacon was famous for her humorous caricatures and ironic etchings and drawings of celebrities of the 1920s and 1930s. She both wrote and illustrated many books, and provided artworks for many other people’s publications, in addition to regularly exhibiting her drawings, paintings, prints, and pastels. In addition to her work as a graphic designer, Bacon was a highly accomplished teacher for over thirty years. Her works appeared in numerous magazine publications including Vanity Fair, Mademoiselle, Harper’s Bazaar, Vogue, Dial, the Yale Review, and the New Yorker. Her vast output of work included etchings, lithographs, and her favorite printmaking technique, drypoint. Bacon’s illustrations have been included in more than 64 children books, including The Lionhearted Kitten. Bacon’s prints are in the collections of the Whitney Museum of American Art, the Brooklyn Museum, and the Museum of Modern Art, all in New York. -
