Vitus Graber
Veit Graber latinized as Vitus Graber (2 July 1844 – 3 March 1892) was an Austrian pioneer of insect physiology, embryology, anatomy, and behaviour. He conducted experiments to demonstrate insect senses and perception while also looking at the structures responsible for them. He was the first to identify what he termed as chordotonal organs. A muscular and pear-shaped structure of unknown function found in the larvae of horseflies described by him is now known as Graber's organ. He was the author of several major books on insects including ''Die Insekten'' (1877–78). Life and career Graber was born in Weer to blacksmith Joseph Mathew and Barbara née Posch. He went to school in Innsbruck and a scholarship allowed him to study zoology at the Leopold-Franzens University from 1864 under Camill Heller. He then trained as a teacher and began to teach in high schools from 1867. He obtained a doctorate in 1868 and habilitated in zoology in 1871 with studies under Eduard Oscar Sch ...

Teutonic Cemetery
The Teutonic Cemetery ( it, Cimitero Teutonico, "Camposanto of the Teutons and the Flemish") is a burial site adjacent to St. Peter's Basilica in Vatican City. Burial is reserved for members of the Confraternity of Our Lady of the German Cemetery, which owns the cemetery. It is a place of pilgrimage for many German-speaking pilgrims. History Located where the Circus of Nero once stood, during the period of the Roman Empire, it was the site of the martyrdom of many of the early Christians of the city. The cemetery chapel of Our Lady of Sorrows marks the spot where St. Peter was killed. It is reported that Pope Leo III gave the land to Charlemagne in 799 for a hospice, called the "Schola Francorum", for German pilgrims. In connection with the hospice was a church dedicated to the Saviour and a graveyard for the burial of the subjects of Charlemagne who died in Rome. Since the fifteenth century the soil of this cemetery has been held to be sacred earth from Jerusalem. This tradition ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Theodor Gartner
Theodor Gartner (4 November 1843 — 29 April 1925) was an Austrian linguist, Romance studies, Romance philologist and professor. Biography He is also known for his study of the Ukrainian language and as a co-author (with Stepan Smal-Stotsky) of the monograph and textbook on the grammar of the Ukrainian language.http://encyclopedia.kiev.ua/articles/files/gartner.pdf After graduating from the University of Vienna, from 1868 to 1885 he taught in schools in Hungary. Since 1885, he was a professor of Romance Philology at the University of Chernivtsi. He conducted studies of Romanian accents on the territory of Bukovina. Living among Ukrainians, he got interested in their language, first of all in grammar, phonetics and vocabulary. He studied Ukrainian language under the guidance of Stepan Smal-Stotsky, the head of Ukrainian language and literature department. Studying with textbooks of that time, he found a certain inconsistency and contradictions in them. In co-authorship wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
German Cockroach
The German cockroach (''Blattella germanica''), colloquially known as the croton bug, is a species of small cockroach, typically about long. In color it varies from tan to almost black, and it has two dark, roughly parallel, streaks on the pronotum running anteroposteriorly from behind the head to the base of the wings. Although ''B. germanica'' has wings, it can barely fly, although it may glide when disturbed. Of the few species of cockroach that are domestic pests, it probably is the most widely troublesome example. It is very closely related to the Asian cockroach, and to the casual observer, the two appear nearly identical and may be mistaken for each other. However, the Asian cockroach is attracted to light and can fly like a moth, while the German cockroach cannot. Biology and pest status The German cockroach occurs widely in human buildings, but is particularly associated with restaurants, food processing facilities, hotels, and institutional establishments such as nur ...

Chordotonal Organ
Chordotonal organs are stretch receptor organs found only in insects and crustaceans. They are located at most joints and are made up of clusters of scolopidia that either directly or indirectly connect two joints and sense their movements relative to one another. They can have both extero- and proprioceptive functions, for example sensing auditory stimuli or leg movement. The word was coined by Vitus Graber in 1882, though he interpreted them as being stretched between two points like a string, sensing vibrations through resonance. Structure Chordotonal organs can be composed of a single scolopidium with only a single sensory, bipolar neuron (such as the tympanal ear of a notodontid moth), or up to several thousand scolopidia, each equipped with up to four sensory neurons (as in the mosquito Johnston's organ). The bipolar sensory neurons each have an apical dendritic structure with a cilium densely packed with microtubules and surrounded by two specialized cells, the scolop ...

University Of Chernivtsi
Chernivtsi National University (full name Yuriy Fedkovych Chernivtsi National University, uk, Чернівецький національний університет імені Юрія Федьковича) is a public university in the City of Chernivtsi in Western Ukraine. One of the leading Ukrainian institutions for higher education, it was founded in 1875 as the Franz-Josephs-Universität Czernowitz when Chernivtsi (Czernowitz) was the capital of the Duchy of Bukovina, a Cisleithanian crown land of Austria-Hungary. Today the university is based at the Residence of Bukovinian and Dalmatian Metropolitans building complex, a UNESCO World Heritage Site since 2011. History In 1775, the Austrian Habsburg monarchy had obtained the territory of Bukovina, which from 1786 was administrated within the Chernivtsi district of Galicia. Under the rule of Emperor Joseph II, the sparsely populated territory was settled by German colonists, mainly from Swabia. Together with the Austri ...

Orthoptera
Orthoptera () is an order of insects that comprises the grasshoppers, locusts, and crickets, including closely related insects, such as the bush crickets or katydids and wētā. The order is subdivided into two suborders: Caelifera – grasshoppers, locusts, and close relatives; and Ensifera – crickets and close relatives. More than 20,000 species are distributed worldwide. The insects in the order have incomplete metamorphosis, and produce sound (known as a "stridulation") by rubbing their wings against each other or their legs, the wings or legs containing rows of corrugated bumps. The tympanum, or ear, is located in the front tibia in crickets, mole crickets, and bush crickets or katydids, and on the first abdominal segment in the grasshoppers and locusts. These organisms use vibrations to locate other individuals. Grasshoppers and other orthopterans are able to fold their wings (i.e. they are members of Neoptera). Etymology The name is derived from the Greek ὀρθό ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Latinisation Of Names
Latinisation (or Latinization) of names, also known as onomastic Latinisation, is the practice of rendering a ''non''-Latin name in a Latin style. It is commonly found with historical proper names, including personal names and toponyms, and in the standard binomial nomenclature of the life sciences. It goes further than romanisation, which is the transliteration of a word to the Latin alphabet from another script (e.g. Cyrillic). For authors writing in Latin, this change allows the name to function grammatically in a sentence through declension. In a scientific context, the main purpose of Latinisation may be to produce a name which is internationally consistent. Latinisation may be carried out by: * transforming the name into Latin sounds (e.g. for ), or * adding Latinate suffixes to the end of a name (e.g. for '' Meibom),'' or * translating a name with a specific meaning into Latin (e.g. for Italian ; both mean 'hunter'), or * choosing a new name based on some attribut ...

Eduard Oscar Schmidt
Eduard Oscar Schmidt (21 February 1823, in Torgau – 17 January 1886, in Kappelrodeck) was a German zoologist and phycologist. Biography He initially studied mathematics and science at Halle, then continued his education in Berlin, where he came under the influence of Christian Gottfried Ehrenberg and Johannes Peter Müller. In 1847 he received his habilitation at the University of Jena, becoming an associate professor during the following year. In 1855 was he appointed professor of zoology at the University of Cracow. Later he taught classes at the Universities of Graz (from 1857) and Strasbourg (from 1872). Schmidt was an early proponent of Darwinian evolutionary thought. He is remembered for his research of Porifera (sponges), particularly species from the Adriatic Sea. Schmidt also made contributions in the field of phycology. As far back as 1862 Oscar Schmidt showed that "cuttings" of sponges will attach themselves and grow. This idea was followed through in the exp ...
