In accounting, the revenue recognition principle states that revenues are earned and recognized when they are realized or realizable, no matter when cash is received. It is a cornerstone of accrual accounting together with the matching principle. Together, they determine the accounting period in which revenues and expenses are recognized. [1]
The same cells that recognize PAMPs on microbial pathogens may bind to the antigen of a foreign blood cell and recognize it as a pathogen because the antigen is unfamiliar. [11] It is not easy to classify red blood cell recognition as intrinsic or extrinsic, as a foreign cell may be recognized as part of the organism if it has the right antigens.
In accounting practices, vendor-specific objective evidence (VSOE) is a method of revenue recognition allowed by US GAAP that enables companies to recognize revenue on specific items on a multi-item sale based on evidence specific to a company that the product has been delivered.
(B) If mutations arise spontaneously during cell divisions prior to plating, each plate will have a highly variable number of mutants. The Luria–Delbrück experiment (1943) (also called the Fluctuation Test ) demonstrated that in bacteria , genetic mutations arise in the absence of selective pressure rather than being a response to it.
The return on equity (ROE) is a measure of the profitability of a business in relation to its equity; [1] where: . ROE = Net Income / Average Shareholders' Equity [1] Thus, ROE is equal to a fiscal year's net income (after preferred stock dividends, before common stock dividends), divided by total equity (excluding preferred shares), expressed as a percentage.
The result of central tolerance is a population of lymphocytes that do not mount immune response towards self-antigens. These cells use their TCR or BCR specificity to recognize foreign antigens, in order to play their specific roles in immune reaction against those antigens.
Cellular immunity protects the body through: T-cell mediated immunity or T-cell immunity: activating antigen-specific cytotoxic T cells that are able to induce apoptosis in body cells displaying epitopes of foreign antigen on their surface, such as virus-infected cells, cells with intracellular bacteria, and cancer cells displaying tumor antigens;
Antibody opsonization is a process by which a pathogen is marked for phagocytosis through coating of a target cell with antibodies. Immunoglobulins participate in molecular tagging of pathogens which display antigens recognised by their specific paratope.
