Technetium (99m Tc) sestamibi ("Cardiolite") is widely used for imaging of the heart. Technetium forms a variety of coordination complexes with organic ligands. Many have been well-investigated because of their relevance to nuclear medicine. [51] Technetium forms a variety of compounds with Tc–C bonds, i.e. organotechnetium complexes.
Trusted Computing (TC) is a technology developed and promoted by the Trusted Computing Group. [1] The term is taken from the field of trusted systems and has a specialized meaning that is distinct from the field of confidential computing . [ 2 ]

The polyoxotechnetate (polyoxometalate of technetium) contains both Tc(V) and Tc(VII) in ratio 4: 16 and is obtained as the hydronium salt [H 7 O 3] 4 [Tc 20 O 68]·4H 2 O by concentrating an HTcO 4 solution. [51] The first empirically isolated polyoxorhenate was the white [Re 4 O 15] 2− and contained Re(VII) in both octahedral and ...
Security clearances can be issued by many United States of America government agencies, including the Department of Defense (DoD), the Department of State (DOS), the Department of Homeland Security (DHS), the Department of Energy (DoE), the Department of Justice (DoJ), the National Security Agency (NSA), and the Central Intelligence Agency (CIA).
In the Atlantic and Eastern Pacific Ocean, a storm with a broad rotating system and low pressure is called a hurricane. In the Western Pacific ocean, they are called typhoons, and in the Indian ...
The additional total cost of one additional unit of production is called marginal cost. The marginal cost can also be calculated by finding the derivative of total cost or variable cost. Either of these derivatives work because the total cost includes variable cost and fixed cost, but fixed cost is a constant with a derivative of 0.
Antigen presentation stimulates T cells to become either "cytotoxic" CD8+ cells or "helper" CD4+ cells.. A cytotoxic T cell (also known as T C, cytotoxic T lymphocyte, CTL, T-killer cell, cytolytic T cell, CD8 + T-cell or killer T cell) is a T lymphocyte (a type of white blood cell) that kills cancer cells, cells that are infected by intracellular pathogens such as viruses or bacteria, or ...
