Since its founding in 1911, the American Association of Variable Star Observers has coordinated, evaluated, analyzed and archived variable star observations made by amateur astronomers and makes the records available to professional astronomers and educators. These records establish light curves depicting the variation in brightness of a star over time. Since professional astronomers do not have the time or the resources to monitor every variable star, astronomy is one of the few sciences where amateurs can make genuine contributions to scientific research. During 2011, the 100th year of the AAVSO's existence, the 20-millionth variable star observation was received into the database; the AAVSO International Database stores over 35 million observations. The organization receives nearly 1,000,000 observations annually from around 2,000 professional and amateur observers and is quoted in scientific journals; the AAVSO is very active in education and public outreach. They hold training workshops for citizen science and publish papers with amateurs as coauthors.
In the 1990s, the AAVSO developed the Hands-On Astrophysics curriculum, now known as Variable Star Astronomy. In 2009, the AAVSO was awarded a three-year $800,000 grant from the NSF to run Citizen Sky, a pro-am collaboration project examining the 2009-2011 eclipse of the star epsilon Aurigae; the current director of the AAVSO is Styliani Kafka, who took over from Arne Henden in February 2015. The previous director of the AAVSO for many decades was Janet Mattei, who died in March 2004 of leukemia; the AAVSO headquarters were located at the residence of its founder William T. Olcott in Norwich, Connecticut. After AAVSO's incorporation in 1918 it de facto moved to Harvard College Observatory, which officially provided an office as the AAVSO headquarters. After it moved around Cambridge before purchasing their first building in 1985 - The Clinton B. Ford Astronomical Data and Research Center. In 2007, the AAVSO purchased and moved into the vacated premises of Sky & Telescope magazine. Minor Planet AAVSO is named for the organization.

The Mad Show is an Off-Broadway musical revue based on Mad Magazine. The music is by the book by Larry Siegel and Stan Hart; the show's various lyricists include Siegel, Marshall Barer, Steven Vinaver, Stephen Sondheim. The revue opened on January 9, 1966, at the New Theatre, New York City, ran for 871 performances; the original cast included Linda Lavin, Jo Anne Worley, Paul Sand, Richard Libertini, MacIntyre Dixon. Sam Pottle conducted the music. Joe Raposo, who became music director for Sesame Street, performed onstage as the Piano Player, shot during the course of each performance, he was bludgeoned with a rubber chicken. The band's drummer was Danny Epstein, who became Sesame Street's music coordinator from 1969 to 2009. Additional sketches, including "Saboteurs," "Babysitter," "Hollywood Surplus," "Zoom," and "Snappy Answers," and the song "Hey, Sweet Momma" appeared during earlier versions of the production; the lyrics of "The Boy From...", a parody of "The Girl from Ipanema", were semi-anonymously written by Stephen Sondheim.
The official songwriting credit went to the linguistically minded pseudonym "Esteban Rio Nido", which translates from the German, via Spanish, to "Stephen River Nest". In the show's playbill, the lyrics were credited to "Nom de Plume"; the production got favorable reviews. The New York Times' Stanley Kaufmann wrote, "It asks for our imaginative support and stimulates and deserves it... it is always amusing." Kaufmann described cast member Libertini as "a bewigged insane beanpole," and Lavin as "an elfin hipster, delicately caustic, with fine timing and a face, a kaleidoscope of the kooky." Life Magazine described the show's freewheeling style: "The Mad Show, based more or less on Mad Magazine and uses the magazine's grinning idiot symbol as a backdrop, is an explosion of insanity, a carnival of caterwauling idiots in fright wigs who sing and scream utterly ridiculous things. But they make an unsettling amount of sense, they attack children who devour their parents. They sing The Hate Song in which do-gooders vow to stamp out hate and conclude by stamping out one another.
They attack TV coverage of pro-football with instant-split-second-ago playbacks while, for Pete's sake, you're missing the touchdown... the show's theme song is "Eccch!" – not a word, but a kind of Bronx cheer, how the Mad people feel about the way things are going." The original cast recording LP was released in 1966 by Columbia Masterworks. The Original cast recording was re-released on February 22, 2005 by DRG Theater.

Hexanitrobenzene known as HNB, is a high-density explosive compound with chemical formula C6N6O12, obtained by oxidizing the amine group of pentanitroaniline with hydrogen peroxide in sulfuric acid. HNB has the undesirable property of being moderately sensitive to light and therefore hard to utilize safely, it is not used in any production explosives applications, though it is used as a precursor chemical in one method of production of TATB, another explosive. HNB was experimentally used as a gas source for explosively pumped gas dynamic laser. In this application, HNB and tetranitromethane are preferred to more conventional explosives because the explosion products CO2 and N2 are a simple enough mixture to simulate gas dynamic processes and quite similar to conventional gas dynamic laser medium; the water and hydrogen products of many other explosives could interfere with vibrational states of CO2 in this type of laser. During World War II a method of synthesis of hexanitrobenzene was suggested in Germany, the product was supposed to be manufactured on a semi-industrial scale according to the following scheme: C6H33 → C6H33 C6H33 → C633 C633 → C66 Complete nitration of benzene is impossible, because the nitro groups are deactivating groups for further nitration.

The Kaweah Delta Medical Center is a 581-bed hospital located in Visalia, United States. It is operated by the Kaweah Delta Health Care District, a political subdivision of the State of California, governed by an elected board of directors. Kaweah Delta Health Care District is a 581-bed district with eight campuses in Tulare and Kings counties serving the Central Valley of Visalia, its campuses consist of Kaweah Delta Medical Center, Kaweah Delta South Campus, Kaweah Delta West Campus, Kaweah Delta Porterville Dialysis, Kaweah Delta Woodlake Health Clinic, Kaweah Delta Exeter Health Clinic, Kaweah Delta Lindsay Health Clinic and Sequoia Regional Cancer Center Radiation Oncology in Hanford. Kaweah Delta operates with less than 1 % of funding coming from taxpayers, it received certification as a Level III Trauma Center in 2010, making it the only trauma center in the Greater Visalia Area. In July 2013 Kaweah Delta established residency training programs in Family Practice and Emergency Medicine, followed by a Psychiatry Residency program in 2014, Surgery and Transitional Year programs in 2015, an Anesthesia residency in 2017.
As of the academic year 2018, all six Kaweah residency programs are accredited by the Accreditation Council of Graduate Medical Education, include a total of over 100 training positions. The Kaweah Delta Hospital District was formed in March 1961 by a vote of the community; the Tulare County Board of Supervisors appointed the first governing board. After the establishment of the District's physical boundaries and years of planning, operation of Kaweah Delta District Hospital commenced July 1, 1963, when the Board of Directors leased the former Visalia Municipal Hospital, a 68-bed facility and provided basic health care needs to the local community; this building, constructed in 1936, was in use until a new hospital was ready in 1969. Kaweah Delta Hospital is still in operation at this site. In 2004, the southwest tower along Mill Creek was constructed, it was the site of the Automobile Club of Southern California after it moved from its first office in Visalia in 1941. Kaweah Delta’s six-floor Acequia Wing, which opened its doors in 2009, is one of Kaweah Delta Medical Center’s most needed and dramatic expansions.
A major emphasis of the new wing was healing the community’s hearts at home. The wing’s dedication to cardiovascular health is everywhere in its new Telemetry Department, Cardiac Surgery and Catheterization Labs, three new surgery suites and in its new Cardiac Intensive Care Unit. Additionally, the wing added 38 post-delivery rooms for mothers and babies and increased the size of the Emergency Department, which handles more than 80,000 visits a year; the expanded ED includes four state-of-the-art trauma bays, four critical-care beds and eight new treatment rooms and a helipad, allowing Kaweah Delta to accept and transfer patients when minutes matter.
