Pyrene is a polycyclic aromatic hydrocarbon consisting of four fused benzene rings, resulting in a flat aromatic system. The chemical formula is C16H10; this yellow solid is the smallest peri-fused PAH. Pyrene forms during incomplete combustion of organic compounds. Pyrene was first isolated from coal tar; as a peri-fused PAH, pyrene is much more resonance-stabilized than its five-member-ring containing isomer fluoranthene. Therefore, it is produced in a wide range of combustion conditions. For example, automobiles produce about 1 μg/km. Oxidation with chromate affords perinaphthenone and naphthalene-1,4,5,8-tetracarboxylic acid, it undergoes a series of hydrogenation reactions, it is susceptible to halogenation, Diels-Alder additions, nitration, all with varying degrees of selectivity. Bromination occurs at one of the 3-positions. Pyrene and its derivatives are used commercially to make dyes and dye precursors, for example pyranine and naphthalene-1,4,5,8-tetracarboxylic acid, it has strong absorbance in UV-Vis in three sharp bands at 330 nm in DCM.

The emission is close to the absorption. The morphology of the signals change with the solvent, its derivatives are valuable molecular probes via fluorescence spectroscopy, having a high quantum yield and lifetime. Pyrene was the first molecule; such excimer appears around 450 nm. Theodor Förster reported this in 1954. Pyrene's fluorescence emission spectrum is sensitive to solvent polarity, so pyrene has been used as a probe to determine solvent environments; this is due to its excited state having a non-planar structure than the ground state. Certain emission bands are unaffected, but others vary in intensity due to the strength of interaction with a solvent. Although it is not as problematic as benzopyrene, animal studies have shown pyrene is toxic to the kidneys and liver, it is now known that pyrene affects several living functions in algae. Experiments in pigs show. Pyrenes are strong electron donor materials and can be combined with several materials in order to make electron donor-acceptor systems which can be used in energy conversion and light harvesting applications.

Feldbach, Switzerland

Feldbach is a village near Rapperswil, Switzerland. It is located on the north bank of the lake of Zurich and is part of the political municipality of Hombrechtikon. In the local dialect it is called Fäldbach. Situated on Zürichsee lake shore, Feldbach is neighboured by Kempraten, nearby the Seedamm, an isthmus between the Zürichsee and the Obersee lake area; the Prehistoric pile dwelling site Seegubel was in close vicinity to the prehistoric lake crossings, neighboured by three other Prehistoric pile dwelling settlements: Freienbach–Hurden Rosshorn, Freienbach–Hurden Seefeld and Rapperswil-Jona–Technikum. Because the lake has grown in size over time, the original piles are now around 4 metres to 7 metres under the water level of 406 metres; as well as being part of the 56 Swiss sites of the UNESCO World Heritage Site Prehistoric pile dwellings around the Alps, the Prehistoric settlmemnt Seegubel is listed in the Swiss inventory of cultural property of national and regional significance as a Class object.

Being Elmo: A Puppeteer's Journey

Being Elmo: A Puppeteer's Journey is a 2011 American documentary film about Kevin Clash, the puppeteer behind the Sesame Street character Elmo who became a rising star and created a global sensation. “Being Elmo: A Puppeteer’s Journey” was one of the most talked about documentaries coming out of the 2011 Sundance Film Festival. The film chronicles the journey of puppeteer Kevin Clash, the unlikely voice and mastermind behind Elmo. Focusing on Clash's childhood dreams and early career in Baltimore, Maryland. Sesame Street camera man James Miller filmed Kevin Clash with Elmo looking at photos of Miller's 2 year-old daughter. After showing the footage to Constance Marks, she started thinking maybe this would be a good documentary, seeing the performer behind the muppet, they brought the idea to Kevin Clash who thought it was a great opportunity to talk about the work he loves.

The Hollywood Reporter's Sundance Review for the film stated, "Being Elmo is a rare documentary that will connect across generations and cultures to delight viewers worldwide for years to come." Rotten Tomatoes gives the film a score of 95% based on reviews from 78 critics. The film received warm-hearted reviews by critics. Roger Ebert noted "We...learn a lot of the tricks behind giving the muppets such distinctive personality." The New York Post reported: "One of the chief pleasures of Sundance is wandering into a movie that you think couldn't amount to anything much and being knocked out by it. The documentary'Being Elmo: A Puppeteer's Journey,' which should make Kevin Clash a household name, is an inspiring and joyous celebration of art, skill and making kids happy... Clash is a remarkable talent, a true master of his field, the importance of what he does is considerable. Sick children have asked to meet Elmo as their dying wish. If you can watch one such encounter without crying, you're a stronger man than I.

Clash, pro that he is, doesn't cry. Because where there is Elmo, there must be happiness." Look at OKC praised: "As director Constance Marks proves in her detailed and emotional documentary Being Elmo: A Puppeteer's Journey, Clash's love of the art form led him to create one of the most popular characters in children's television."

He introduced the diagnostic technique of cutaneous ultrasound in Spain, is an associate professor at the Autonomous University of Madrid, is responsible for the Dermatological Ultrasound Unit at the Puerta de Hierro University Hospital in Majadahonda, he has authored several essays and academic articles about dermatology. Roldán received a doctorate in Medicine and Surgery with the thesis Children's Dermatological Surgery at the Gregorio Marañon Hospital: clinical analysis, economic profitability and post-surgical satisfaction in 2010 and is a graduate in Medicine from the Autonomous University of Madrid, he specialized in diagnostic imaging in its applications. In publishing the article "Cutaneous Ultrasound" in the journal Actas Dermo-Sifiliográficas, Roldán introduced the diagnostic technique of cutaneous ultrasound in Spain, used for the first time in the Hispanic world by the radiologist Dr. Wortsman in Chile. New investigations and applications of this diagnostic technique allowed for the detection of pathologies, including skin cancer or cutaneous malignant melanoma.

Cutaneous ultrasound is used to diagnose inflammatory processes, nail disorders, hair diseases and derma-aesthetics.

Berkshire (NH train)

The Berkshire was a New York, New Haven and Hartford Railroad named train running from New York City's Grand Central Terminal to Pittsfield, Massachusetts. It was the longest-running north–south train in Litchfield Hills of western Connecticut and the Berkshires of Massachusetts. From New York City it followed the New Haven Line to South Norwalk, the Danbury Line to Danbury and the Berkshire Division to Pittsfield, it began in the 1940s and ran until 1968. The train was preceded by the Berkshire Express, of 1939-1941, it terminated at Pittsfield Union Station until 1960, when the New Haven moved it to another station in the city. While the route operated each day excepting Sunday, there were local stops unnamed trains available on Sundays. At peak years of post-World War II service the route was supplemented by other named trains for the New Haven's Berkshire Division route: Housatonic, Mahaiwe, Taconic; the route served as a path to country homes of New Yorkers, as well as to towns such as Canaan and New Milford in the transportation service-neglected northwest Connecticut, an area lacking Interstate highways or major airports.

The route south of Danbury Union Station towards South Norwalk station was electrified until 1961. North from New Milford to Canaan, short of the Connecticut-Massachusetts state line, the route followed the Housatonic River. In summer months the train made stops in Lenox, the town hosting the Tanglewood Music Festival. By 1961 the Berkshire was cut to a Friday north-bound run; the diner-lounge was eliminated by 1961 in favor of parlor cars. In 1968, the Berkshire name was dropped, unnamed trains served the route until 1971 when the New Haven successor Penn Central discontinued service on the line.
