Third Cambridge Catalogue Of Radio Sources
The Third Cambridge Catalogue of Radio Sources (3C) is an astronomical catalogue of celestial radio sources detected originally at 159 MHz, and subsequently at 178 MHz. History 3C The catalogue was published in 1959 by members of the Cavendish Astrophysics Group, Radio Astronomy Group of the University of Cambridge. Entries in the catalogue are identified by the prefix "3C" followed by the entry number, with a space - for example, 3C 273. The catalogue was produced using the Cambridge Interferometer on the west side of Cambridge. The interferometer had previously been used for the Second Cambridge Catalogue of Radio Sources (2C) survey, published in 1955. 3CR The catalogue was subsequently revised by Bennett in 1962 using observations at 178 MHz, and for many years '3CR' was considered as the definitive listing of the brighter radio sources in the Northern Hemisphere. The revision resulted in a number of sources being deleted from the catalogue (as being below the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taiwan
Taiwan, officially the Republic of China (ROC), is a country in East Asia, at the junction of the East and South China Seas in the northwestern Pacific Ocean, with the People's Republic of China (PRC) to the northwest, Japan to the northeast, and the Philippines to the south. The territories controlled by the ROC consist of 168 islands, with a combined area of . The main island of Taiwan, also known as ''Formosa'', has an area of , with mountain ranges dominating the eastern two-thirds and plains in the western third, where its highly urbanised population is concentrated.

Stalag III-C
Stalag III-C was a German Army World War II prisoner-of-war camp for Allied soldiers. It was located on a plain near the village of Alt Drewitz bei Küstrin then located in the Neumark of the province of Brandenburg (now Drzewice, Kostrzyn nad Odrą, Poland), about east of Berlin. Initially the camp served as a place of internment for several thousand soldiers and NCOs from Poland, France, Britain, Yugoslavia and Belgium. From 1943, a number of Italian POWs were also held there. From 1944, soldiers from the United States of America were kept there too. The majority of the Soviet prisoners (up to 12,000) were killed or starved to death. Most of the lower rank prisoners were sent to Arbeitskommandos to work in industry and on farms in Brandenburg. However the administration stayed with the Stammlager. Timeline * June 1940: the camp was established from Küstrin (Kostrzyn nad Odrą) for Belgian and French prisoners from the Battle of France. * May to June 1941: Yugoslavian prisoner ...

3C-P
3C-P (α-Methyl-4-propoxy-3,5-dimethoxyphenethylamine) is a psychedelic phenethylamine. It has structural and pharmacodynamic properties similar to the drugs mescaline, proscaline, and amphetamine. Little information exists on the human pharmacology of 3C-P, but a psychedelic dosage appears to be 20–40 mg, and is accompanied by stimulant and psychedelic effects such as visual enhancement and distortion. It can be synthesized from syringaldehyde by reaction with ''n''-propyl iodide followed by condensation with nitroethane and reduction.

3C-BZ
3C-BZ (4-benzyloxy-3,5-dimethoxyamphetamine) is a lesser-known psychedelic drug and a substituted amphetamine. 3C-BZ was first synthesized by Alexander Shulgin. In his book '' PiHKAL'', the dosage range is listed as 25–200 mg and the duration as 18–24 hours. According to anecdotal reports from the substance's entry in PiHKAL, 3C-BZ's effects can vary significantly, ranging from intensified emotions and strange dreams, to effects similar to those of LSD or TMA. Very little data exists about the pharmacological properties, metabolism, and toxicity of 3C-BZ. Synthesis 3C-BZ was originally synthesized by Alexander Shulgin starting from 5-methoxyeugenol (4-allyl-2,6-dimethoxyphenol) through a reaction with benzyl chloride to form the benzyloxy derivative of 5-methoxyeugenol. The obtained benzyl derivative was reacted with tetranitromethane to form 1- -(Benzyloxy)-3,5-dimethoxyphenyl2-nitro-1-propene, from which 3C-BZ is obtained by reduction of the nitropropene with lithiu ...

Ganesha (psychedelic)
Ganesha (2,5-dimethoxy-3,4-dimethylamphetamine) is a lesser-known psychedelic drug. It is also a substituted amphetamine. It was first synthesized by Alexander Shulgin. In his book '' PiHKAL'', the dosage range is listed as 24–32 mg. The drug is usually taken orally, although other routes such as rectally may also be used. Ganesha is synthesized from 2,5-dimethoxy-3,4-dimethylbenzaldehyde. Ganesha is the amphetamine analog of 2C-G. It is a particularly long lasting drug, with the duration listed in ''PiHKAL'' as being 18–24 hours, which might make it undesirable to some users. It is named after the Hindu deity, Ganesha.

Substituted Amphetamines
Substituted amphetamines are a class of compounds based upon the amphetamine structure; it includes all derivative compounds which are formed by replacing, or substituting, one or more hydrogen atoms in the amphetamine core structure with substituents. The compounds in this class span a variety of pharmacological subclasses, including stimulants, empathogens, and hallucinogens, among others. Examples of substituted amphetamines are amphetamine (itself), methamphetamine, ephedrine, cathinone, phentermine, mephentermine, bupropion, methoxyphenamine, selegiline, amfepramone (diethylpropion), pyrovalerone, MDMA (ecstasy), and DOM (STP). Some of amphetamine's substituted derivatives occur in nature, for example in the leaves of ''Ephedra'' and khat plants. Amphetamine was first produced at the end of the 19th century. By the 1930s, amphetamine and some of its derivative compounds found use as decongestants in the symptomatic treatment of colds and also occasionally as psychoac ...

Chromosome Conformation Capture
Chromosome conformation capture techniques (often abbreviated to 3C technologies or 3C-based methods) are a set of molecular biology methods used to analyze the spatial organization of chromatin in a cell. These methods quantify the number of interactions between genomic loci that are nearby in 3-D space, but may be separated by many nucleotides in the linear genome. Such interactions may result from biological functions, such as promoter- enhancer interactions, or from random polymer looping, where undirected physical motion of chromatin causes loci to collide. Interaction frequencies may be analyzed directly, or they may be converted to distances and used to reconstruct 3-D structures. The chief difference between 3C-based methods is their scope. For example, when using PCR to detect interaction in a 3C experiment, the interactions between two specific fragments are quantified. In contrast, Hi-C quantifies interactions between all possible pairs of fragments simultaneously. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alpha-tubulin 3C
Tubulin alpha-3C/D chain is a protein that in humans is encoded by the ''TUBA3C'' gene. Function Microtubules of the eukaryotic cytoskeleton perform essential and diverse functions and are composed of a heterodimer of alpha and beta tubulin. The genes encoding these microtubule constituents are part of the tubulin superfamily, which is composed of six distinct families. Genes from the alpha, beta and gamma tubulin families are found in all eukaryotes. The alpha and beta tubulins represent the major components of microtubules, while gamma tubulin plays a critical role in the nucleation of microtubule assembly. There are multiple alpha and beta tubulin genes and they are highly conserved among and between species. This gene is an alpha tubulin gene that encodes a protein 99% to the mouse testis-specific Tuba3 and Tuba7 gene products. This gene is located in the 13q11 region, which is associated with the genetic diseases Clouston hidrotic ectodermal dysplasia and Kabuki syndrome. A ...

Agile Software Development
In software development, agile (sometimes written Agile) practices include requirements discovery and solutions improvement through the collaborative effort of self-organizing and cross-functional teams with their customer(s)/ end user(s), adaptive planning, evolutionary development, early delivery, continual improvement, and flexible responses to changes in requirements, capacity, and understanding of the problems to be solved. Popularized in the 2001 ''Manifesto for Agile Software Development'', these values and principles were derived from and underpin a broad range of software development frameworks, including Scrum and Kanban. While there is much anecdotal evidence that adopting agile practices and values improves the effectiveness of software professionals, teams and organizations, the empirical evidence is mixed and hard to find. History Iterative and incremental software development methods can be traced back as early as 1957, Gerald M. Weinberg, as quoted in " ...
