Alpha male and beta male are outdated terms for men derived from the designations of alpha and beta animals in ethology. They may also be used with other genders, such as women, or additionally use other letters of the Greek alphabet (such as omega). The popularization of these terms to describe humans has been widely criticized by scientists ...
The two types of beta decay are known as beta minus and beta plus.In beta minus (β −) decay, a neutron is converted to a proton, and the process creates an electron and an electron antineutrino; while in beta plus (β +) decay, a proton is converted to a neutron and the process creates a positron and an electron neutrino. β + decay is also known as positron emission.
The software release life cycle is the process of developing, testing, and distributing a software product (e.g., an operating system).It typically consists of several stages, such as pre-alpha, alpha, beta, and release candidate, before the final version, or "gold", is released to the public.
A high-ranking male mandrill advertises his status with bright facial coloration. [1]In the zoological field of ethology, a dominance hierarchy (formerly and colloquially called a pecking order) is a type of social hierarchy that arises when members of animal social groups interact, creating a ranking system.
Adrenergic competitive antagonists are shorter lasting than the other two types of antagonists. While the antagonists for alpha and beta receptors are usually different compounds, there has been recent drug development that effects both types of the adrenoreceptors. Phentolamine, an adrenergic antagonist
The slang term "Chad" originated in the UK during World War II and was employed in a similar humorous manner as Kilroy was here. [1] It later came into use in Chicago [2] as a derogatory way to describe a young, wealthy man from the city's northern suburbs, typically single and in his twenties or early thirties. [2]
An example of a receptor site that possesses basal activity and for which inverse agonists have been identified is the GABA A receptors.Agonists for GABA A receptors (such as muscimol) create a relaxant effect, whereas inverse agonists have agitation effects (for example, Ro15-4513) or even convulsive and anxiogenic effects (certain beta-carbolines).
In general, pure beta-adrenergic agonists have the opposite function of beta blockers: beta-adrenoreceptor agonist ligands mimic the actions of both epinephrine- and norepinephrine- signaling, in the heart and lungs, and in smooth muscle tissue; epinephrine expresses the higher affinity.
