U4 Spliceosomal RNA
The U4 small nuclear Ribo-Nucleic Acid (U4 snRNA) is a non-coding RNA component of the major or U2-dependent spliceosome – a eukaryotic molecular machine involved in the splicing of pre-messenger RNA (pre-mRNA). It forms a duplex with U6, and with each splicing round, it is displaced from the U6 snRNA (and the spliceosome) in an ATP-dependent manner, allowing U6 to re-fold and create the active site for splicing catalysis. A recycling process involving protein Brr2 releases U4 from U6, while protein Prp24 re-anneals U4 and U6. The crystal structure of a 5′ stem-loop of U4 in complex with a binding protein has been solved. Biological role The U4 snRNA has been shown to exist in a number of different formats including: bound to proteins as a small nuclear Ribo-Nuclear Protein snRNP, involved with the U6 snRNA in the di-snRNP, as well as involved with both the U6 snRNA and the U5 snRNA in the tri-snRNP. The different formats have been proposed to coincide with different temp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Unemployment
Unemployment, according to the OECD (Organisation for Economic Co-operation and Development), is people above a specified age (usually 15) not being in paid employment or self-employment but currently available for Work (human activity), work during the reference period. Unemployment is measured by the unemployment rate, which is the number of people who are unemployed as a percentage of the labour force (the total number of people employed added to those unemployed). Unemployment can have many sources, such as the following: * new technology, technologies and inventions * the status of the economy, which can be influenced by a recession * competition caused by globalization and international trade * Policy, policies of the government * regulation and market (economics), market Unemployment and the status of the economy can be influenced by a country through, for example, fiscal policy. Furthermore, the monetary authority of a country, such as the central bank, can influ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anti-Corruption Resource Centre
Anti-corruption (or anticorruption) comprises activities that oppose or inhibit corruption. Just as corruption takes many forms, anti-corruption efforts vary in scope and in strategy. A general distinction between preventive and reactive measures is sometimes drawn. In such framework, investigative authorities and their attempts to unveil corrupt practices would be considered reactive, while education on the negative impact of corruption, or firm-internal compliance programs are classified as the former. History Early history The code of Hammurabi (), the Great Edict of Horemheb (), and the Arthasastra (2nd century BC) are among the earliest written proofs of anti-corruption efforts. All of those early texts are condemning bribes in order to influence the decision by civil servants, especially in the judicial sector. During the time of the Roman empire corruption was also inhibited, e.g. by a decree issued by emperor Constantine in 331. In ancient times, moral princ ...

Gulfstream IV
The Gulfstream IV (or G-IV or GIV) and derivatives are a family of twinjet aircraft, mainly for private or business use. They were designed and built by Gulfstream Aerospace, a General Dynamics company based in Savannah, Georgia, United States, from 1985 until 2018. Aircraft power is provided by two Rolls-Royce RB.183 Tay turbofans. Upon delivery of the last G450, over 900 GIV/GIV-SP/G450 units had been produced. The last G450 was delivered on 19 January 2018 after 365 deliveries over 12 years, ending a 30-year production run, to be replaced by the G500. Development Gulfstream, in collaboration with Grumman, began work on the Gulfstream IV in March 1983 as a re-engined, stretched fuselage derivative of the Gulfstream III. The first GIV made its maiden flight on September 19, 1985. The model received type certification from the FAA on April 22, 1987. The G-IV entered into service with serial number 1000 in 1987 and was upgraded to the special purpose ''GIV-SP'' version at se ...

Aero Commander (aircraft)
The Aero Commander 500 family is a series of light-twin piston-engined and turboprop aircraft originally built by the Aero Design and Engineering Company in the late 1940s, renamed the Aero Commander company in 1950, and a division of Rockwell International from 1965. The initial production version was the 200-mph, seven-seat Aero Commander 520. An improved version, the 500S, manufactured after 1967, is known as the Shrike Commander. Larger variants are known by numerous model names and designations, ranging up to the 330-mph, 11-seat Model 695B/Jetprop 1000B turboprop. Design and development The idea for the Commander light business twin was conceived by Ted R. Smith, Ted Smith, a project engineer at the Douglas Aircraft Company. Working part-time after hours throughout 1944, a group of Douglas A-20 Havoc, A-20 engineers formed the Aero Design and Engineering Company to design and build the proposed aircraft with a layout similar to their A-20 bomber. Originally, the new com ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Haplogroup U4 (mtDNA)
Haplogroup U is a human mitochondrial DNA haplogroup (mtDNA). The clade arose from haplogroup R, likely during the early Upper Paleolithic. Its various subclades (labelled U1–U9, diverging over the course of the Upper Paleolithic) are found widely distributed across Northern and Eastern Europe, Central, Western and South Asia, as well as North Africa, the Horn of Africa, and the Canary Islands. Origins Haplogroup U descends from the haplogroup R mtDNA branch of the phylogenetic tree. The defining mutations (A11467G, A12308G, G12372A) are estimated to have arisen between 43,000 and 50,000 years ago, in the early Upper Paleolithic (around 46,530 ± 3,290 years before present, with a 95% confidence interval per Behar et al., 2012). Ancient DNA classified as belonging to the U* mitochondrial haplogroup has been recovered from human skeletal remains found in Western Siberia, which have been dated to c. 45,000 years ago.
