The Delta Regional Authority (DRA) is a Federal-State partnership whose mission it is to improve the quality of life for the residents of the Mississippi Delta. The Delta Regional Authority serves 252 counties and parishes in parts of eight states: Alabama , Arkansas , Illinois , Kentucky , Louisiana , Mississippi , Missouri , and Tennessee .
Amphetamine, an NDRA and one of the most well-known DRAs. 4-Methylaminorex (4-MAR), the cis- isomer being one of the most dopamine-selective NDRAs known.. A dopamine releasing agent (DRA) is a type of drug which induces the release of dopamine in the body and/or brain.
A dopamine antagonist, also known as an anti-dopaminergic and a dopamine receptor antagonist (DRA), is a type of drug which blocks dopamine receptors by receptor antagonism. Most antipsychotics are dopamine antagonists, and have been used in treating schizophrenia , bipolar disorder , and stimulant psychosis . [ 1 ]
A replacement-level player is defined by FanGraphs as contributing 17.5 runs fewer than a player of league-average performance, over 600 plate appearances. [4] Therefore, a 1.0 WAR player has contributed an estimated −7.5 runs relative to average over the same number of plate appearances, a 2.0 WAR player has contributed +2.5 runs, and a 5.0 ...
Dielectric resonator antenna; Dopamine receptor antagonist, first generation antipsychotics; Dopamine releasing agent, a class of drugs; Downregulated-in-adenoma, an anion exchanger
HLA-DR52 is an HLA-DR serotype that recognizes gene products of HLA-DRB3 locus. Three allele groups can produce 35 isoforms. DRB3, DRB4, and DRB5 are minor DR beta-encoding loci, and they have been recognized as having distinct evolution, [1] having diverged from DRB1 around 4 million years ago.
Regular army units were armed with Soviet-made weapons and military equipment. Most DRA soldiers were equipped with either AKM and AK-74 assault rifles. [55] In the early 1980s, civilian self-defense forces were equipped with older PPSh-41 submachine guns, which were phased out for more modern rifles closer to the regime's end. [56]
The dimension of a DRA is the order of , where is the free-space wavelength and is the dielectric constant of the resonator material. Thus, by choosing a high value of ε r {\displaystyle \varepsilon _{r}} ( ε r ≈ 10 − 100 {\displaystyle \varepsilon _{r}\approx 10-100} ), the size of the DRA can be significantly reduced.
