Labeo bata: Labeo bata is fish in genus Labeo.  It is commonly known as bata, and is a native fish to India and Bangladesh.  It is a popular game fish and is popular for its taste.  It lives in ponds, rivers, etc.  Its maximum length is 25 - .  It eats protozoa, algae, and tiny fishes.  It is a slow-moving fish, so with any active and aggressive it will be nervous.  The age and growth of Labeo bata (Ham.)  was studied by the analysis of annuli found on the scale and by length-frequency distribution.  The fish attained lengths of 131, 194, 236, 277, 314, 341 and 364 mm at the end of the 1st, 2nd, 3rd, 4th, 5th, 6th and 7th years of life respectively.  The increase in length of scale bears a constant relationship with the increase in length of fish.  The growth rate of the fish was found high during the 1st and 2nd years, and decreased gradually afterwards till the 7th year.  Both sexes showed more or less similar growth rate.  The seasonal growth curve was chiefly influenced by feeding intensity in fishes of 1st year class, while in adults it was affected by feeding intensity as well as by maturation of the gonads.  The body is elongate.  Its dorsal profile is more convex than the ventral.  The snout slightly projects beyond the mouth, often studded with pores (Talwar and Jhingran, 1991).  A pair of small maxillary barbells is hidden inside the labial fold.  There is no cartilaginous support to the lips.  The dorsal originates midway between the snout tip and the anterior base of anal.  Pelvics originate slightly nearer to the snout tip than to the caudal base (Rahman, 1989).  It is bluish or darkish on upper half, silvery below, and the opercle is light orange.  Its food comprises crustaceans and an insect larva in early stages.  This fish is found throughout India(West Bengal,Odisha,Tripura etc.)and Bangladesh .  Ponds, rivers, rivulets are its main habitats (Bhuiyan, 1964).  It is listed as a threatened species by IUCN Bangladesh (2000).

Klaus Oeggl: Klaus Oeggl (born 1955 in Innsbruck) is an Austrian botanist, and deals with palaeoecology and archaeobotany.  He is well known for his studies on the life-circumstances and on the environment of the Neolithic glacier mummy „Ötzi“.

Ötzi: Ötzi (] ; also called the Iceman, the Similaun Man, the Man from Hauslabjoch, the Tyrolean Iceman, and the Hauslabjoch mummy) is a nickname given to the well-preserved natural mummy of a man who lived around 3,300 BCE, more precisely between 3359 and 3105 BCE, with a 66 percent chance that he died between 3239 and 3105 BCE.  The mummy was found in September 1991 in the Ötztal Alps, hence the nickname "Ötzi", near Similaun mountain and Hauslabjoch on the border between Austria and Italy.  He is Europe's oldest known natural human mummy, and has offered an unprecedented view of Chalcolithic Europeans.  His body and belongings are displayed in the South Tyrol Museum of Archaeology in Bolzano, South Tyrol, Italy.

Horace Winchell Magoun: Horace Winchell Magoun (June 23, 1907 – March 6, 1991) studied medicine first at the Rhode Island State College and the Syracuse University, graduating in medicine in 1931.  In 1934 earned a Ph.D. in anatomy at the Faculty of Medicine 'Northwestern University, and remained in it first as a university assistant (1934–1937) and then as professor of microscopic anatomy (1937–1950).  In 1948, in collaboration with the Italian neurophysiologist Giuseppe Moruzzi, Magoun identified the brain center responsible for the state of sleep: electrical stimulation of the brain stem, by Moruzzi and Magoun found a link between the station cerebellum and motor cortex, producing EEG waves typical of a state of intense supervision.  With further investigation showed that both the deep brain stimulation of this structure, which they named "reticular formation", caused the awakening of the animal, while its destruction made him fall into a coma permanent.  With this guide "classic".  Are considered "classics" those works that have been cited in over 400 scientific papers and Moruzzi Magoun laid the foundations for studying the physiology of sleep.

Wallace Hall (Simpson College): Wallace Hall, formerly known as Science Hall, is a historic building located on the campus of Simpson College in Indianola, Iowa, United States.  The 2½-story, brick structure was designed by Wichita, Kansas architect, and Indianola native, William T. Proudfoot.  He would become partner in the prominent Des Moines architectural firm of Proudfoot & Bird.  This is the firm's earliest known extant building in Iowa.  The Romanesque Revival style is found in the round arched openings, stone trim, decorative brickwork, prominent gables centered at the front and rear elevations, and slender turrets on the corners.  The building was completed in 1888.  George Washington Carver studied art in the attic classroom while attending Simpson in 1890-1891.  A new science hall was completed in 1956, and named for Carver.  This building remained vacant for the most part, and suffered a fire a few years later.  It was eventually renovated, and on June 4, 1967 it was rededicated and at that time was renamed.  It now honors Henry A. Wallace, a geneticist and former Vice President of the United States.  It was listed on the National Register of Historic Places in 1991.

Adelheid Gnaiger: Adelheild Gnaiger (1916–1991) was an Austrian architect.  She studied at the Vienna Institute of Technology, now TU Wien, graduating in 1937.  After working in an office in Zurich, she took her licensing exams in 1950 to found her own office.  She was the first woman to head her own architectural practice in Vorarlberg.  Her office worked on civic and private commissions, including banks, schools and public buildings.  She was the architect of the ... and also designed of a number of private residences.  Her architecture, defined by a style that negotiated between modern architecture and tradition, influenced the architecture of Vorarlberg in the post-war period.  Her life and work was the subject of Ingrid Holzschuh's book "Adelheid Gnaiger.  Die erste Architektin Vorarlbergs" (Adelheid Gneiger.  First Architect of Vorarlberg) with contributions by a number of notable Austrian art historians.  The book was published in collaboration with the vorarlberg museum.

Reinhold Marxhausen: Reinhold Pieper Marxhausen (April 13, 1922 - April 23, 2011), was an American artist known for his work in sculpture, mosaic, painting and found object art.  Reinhold studied at Valparaiso University, the Art Institute in Chicago, the Ray-Vogue School in Chicago and Mills College in California.  He became the first art department chair at Concordia University, Nebraska in 1951, teaching there until his retirement in 1991.  During this time, he gained national recognition through various exhibits across the country.  His most well-known works include two massive mosaic murals in the Nebraska State Capitol and the small sound sculptures called "Stardust".

Theron Randolph: Theron Randolph (1906 – September 29, 1995) was a physician, allergist, and researcher from the United States.  He studied food allergies, chemical sensitivities, and preventive care.  Randolph, along with other American allergists, objected to the definition of allergies as arising from serological abnormalities; this definition, common among European allergists of Randolph's day, excluded from consideration the kinds of adverse environmental reactions that Randolph studied.  Randolph authored four books and over 300 medical articles and is considered the "Father of Clinical Ecology".  According to his obituary in the "New York Times", "traditional medical bodies ... which contended there was no scientific basis for his approach, are sharply skeptical of Dr. Randolph's unorthodox therapies".  The obituary then goes on to note a, "small but discernible shift in attitude toward the issue of chemical sensitivity.  In 1991, a workshop of the National Academy of Sciences agreed on a definition, designating as a syndrome cases in which patients react to chemicals at levels far lower than what is normally tolerated."

Wilson–Turner syndrome: Wilson-Turner Syndrome (WTS), also known as Mental Retardation X Linked Syndromic 6 (MRXS6), or Mental Retardation X Linked with Gynecomastia and Obesity is a congenital condition characterized by intellectual disability and associated with childhood-onset obesity.  It is found to be linked to the X chromosome and caused by a mutation in the HDAC8 gene, which is located on the q arm at locus 13.1.  Individuals with Wilson–Turner syndrome have a spectrum of physical characteristics including dysmorphic facial feature, hypogonadism, and short stature.  Females generally have milder phenotype than males.  The study of X-linked mental retardation began in 1943 when Martin and Bell reported a family exhibiting sex-linked mental retardation.  However, this syndrome was not recognized until 1991.  Wilson studied 14 males from 3 successive generations that presented hypogonadism, mental retardation, gynecomastia, short stature, among other symptoms.  Eventually, this disorder was ruled distinct from a syndrome presented by Prader and Willi (Prader-Willi syndrome) because of its mode of inheritance, gynecomastia, and presence of small hands and feet.  However, there are some speculations that this syndrome is in the same spectrum as the Cornelia de Lange syndrome.  This disorder affects all demographics equally and is seen in less than one in one million people.
