Rara

Rara is a form of festival music that originated in Haïti, that is used for street processions, typically during Easter Week. The music centers on a set of cylindrical bamboo trumpets called vaksen (which may also be made of metal pipes), but also features drums, maracas, güiras or güiros (a percussion instrument), and metal bells, as well as sometimes also cylindrical metal trumpets which are made from recycled metal, often coffee cans. The vaksen-s perform repeating patterns in hocket and often strike their instruments rhythmically with a stick while blowing into them. In the modern day, standard trumpets and saxophones may also be used. The genre though predominantly Afro-based has some Taino Amerindian elements to it such as the use of güiros and maracas.

The songs are always performed in Haitian Kreyòl and typically celebrate the African ancestry of the Afro-Haitian masses. Vodou is often implemented through the procession. The genre was imported to the Dominican Republic and is now an integral part of the Afro-Dominican music scene, where it is known colloquially as gagá. In the Dominican Republic, the music is often played by the Afro-Dominican population as a cultural tribute to their African ancestors in the same manner as their counterparts in Haiti. Rara in Haiti is often used for political purposes, with candidates commissioning songs praising them and their campaigns. Rara lyrics also often address difficult issues, such as political oppression or poverty. Consequently, rara groups and other musicians have been banned from performing and even forced into exile—most notably, folk singer Manno Charlemagne who later returned to Haïti and was elected mayor of Port-au-Prince in the 1990s.

Retinoic acid receptor alpha

Retinoic acid receptor alpha (RAR-α), also known as NR1B1 (nuclear receptor subfamily 1, group B, member 1) is a nuclear receptor that in humans is encoded by the RARA gene.

Function

Retinoid signaling is transduced by 2 families of nuclear receptors, retinoic acid receptor (RAR) and retinoid X receptor (RXR), which form RXR/RAR heterodimers. In the absence of ligand, DNA-bound RXR/RARA represses transcription by recruiting the corepressors NCOR1, SMRT (NCOR2), and histone deacetylase. When ligand binds to the complex, it induces a conformational change allowing the recruitment of coactivators, histone acetyltransferases, and the basic transcription machinery.

Clinical significance

Translocations that always involve rearrangement of the RARA gene are a cardinal feature of acute promyelocytic leukemia (APL; MIM 612376). The most frequent translocation is t(15,17)(q21;q22), which fuses the RARA gene with the PML gene.

Interactions

Retinoic acid receptor alpha has been shown to interact with:

.com

The domain name com is a top-level domain (TLD) in the Domain Name System of the Internet. Its name is derived from the word commercial, indicating its original intended purpose for domains registered by commercial organizations. However, eventually the distinction was lost when .com, .org and .net were opened for unrestricted registration.

The domain was originally administered by the United States Department of Defense, but is today operated by Verisign, and remains under ultimate jurisdiction of U.S. law. Verisign Registrations in com are processed via registrars accredited by ICANN. The registry accepts internationalized domain names.

The domain was one of the original top-level domains (TLDs) in the Internet when the Domain Name System was implemented in January 1985, the others being edu, gov, mil, net, org, and arpa. It has grown into the largest top-level domain.

History

The domain com was as one of the first set of top-level domains when the Domain Name System was first implemented for use on the Internet in January 1985. The domain was administered by the U.S. Department of Defense (DoD), however the department contracted the domain maintenance to SRI International. SRI created DDN-NIC, also known as SRI-NIC, or simply the NIC (Network Information Center), then accessible online with the domain name nic.ddn.mil. Beginning October 1, 1991, an operations contract was awarded to Government Systems Inc. (GSI), which sub-contracted it to Network Solutions Inc. (NSI).

Comè

Comè is a town and arrondissement located in the Mono Department of Benin. The commune covers an area of 163 square kilometres and as of 2012 had a population of 33,507 people. It was home to a refugee camp for Togolese refugees until it was closed in 2006.

COM file

A COM file is a type of simple executable file. On the Digital Equipment operating systems of the 1970s, .COM was used as a filename extension for text files containing commands to be issued to the operating system (similar to a batch file). With the introduction of CP/M (a microcomputer operating system), the type of files commonly associated with COM extension changed to that of executable files. This convention was later carried over to MS-DOS. Even when complemented by the more general .exe file format for executables, the compact COM files remain viable and frequently used in MS-DOS.

The .COM file name extension has no relation to the .com (for "commercial") top-level Internet domain name. However, this similarity in name has been exploited by malicious computer virus writers.

MS-DOS binary format

The COM format is the original binary executable format used in CP/M and MS-DOS. It is very simple; it has no header (with the exception of CP/M 3 files), and contains no standard metadata, only code and data. This simplicity exacts a price: the binary has a maximum size of 65,280 (FF00h) bytes (256 bytes short of 64 KB) and stores all its code and data in one segment.
