Ytterbium monotelluride is an inorganic compound, one of the tellurides of ytterbium, with the chemical formula YbTe. Preparation. Ytterbium monotelluride can be produced by the high-temperature reduction reaction of ytterbium(III) telluride (Yb 2 Te 3), or by the reaction of ytterbium(III) chloride, tellurium and hydrogen:
Long chain fatty acyl-CoA synthetase homodimer from Thermus thermophilus. [ 1] The long chain fatty acyl-CoA ligase (or synthetase) is an enzyme ( EC 6.2.1.3) of the ligase family that activates the oxidation of complex fatty acids. [ 2] Long chain fatty acyl-CoA synthetase catalyzes the formation of fatty acyl-CoA by a two-step process ...

Alternative pathway. (Some labels are in Polish.) The alternative pathway is a type of cascade reaction of the complement system and is a component of the innate immune system, a natural defense against infections. The alternative pathway is one of three complement pathways that opsonize and kill pathogens. The pathway is triggered when the C3b ...
Mast cell activation syndrome (MCAS) is a term referring to one of two types of mast cell activation disorder (MCAD); the other type is idiopathic MCAD. [1] MCAS is an immunological condition in which mast cells inappropriately and excessively release chemical mediators, resulting in a range of chronic symptoms, sometimes including anaphylaxis or near-anaphylaxis attacks.
Neutron activation. Neutron activation is the process in which neutron radiation induces radioactivity in materials, and occurs when atomic nuclei capture free neutrons, becoming heavier and entering excited states. The excited nucleus decays immediately by emitting gamma rays, or particles such as beta particles, alpha particles, fission ...
In computing, serial presence detect (SPD) is a standardized way to automatically access information about a memory module.Earlier 72-pin SIMMs included five pins that provided five bits of parallel presence detect (PPD) data, but the 168-pin DIMM standard changed to a serial presence detect to encode more information.
