Within economics, margin is a concept used to describe the current level of consumption or production of a good or service. [1] Margin also encompasses various concepts within economics, denoted as marginal concepts, which are used to explain the specific change in the quantity of goods and services produced and consumed.
The marginal zone is the region at the interface between the non-lymphoid red pulp and the lymphoid white-pulp of the spleen. (Some sources consider it to be the part of red pulp which borders on the white pulp, while other sources consider it to be neither red pulp nor white pulp.) A marginal zone also exists in the lymphoid follicles of lymph ...
The ventricular and subventricular zones exist inferior to the intermediate zone and communicate with other zones through cell signalling. These zones additionally create neurons destined to migrate to other areas in the cortex. [1] [6] The marginal zone, along with the cortical zone, make up the 6 layers that form the cortex. This zone is the ...
A marginal benefit is a benefit (howsoever ranked or measured) associated with a marginal change. The term “marginal cost” may refer to an opportunity cost at the margin, or more narrowly to marginal pecuniary cost — that is to say marginal cost measured by forgone cash flow. Other marginal concepts include (but are not limited to ...
In humans the splenic marginal zone B cells have evidence of somatic hypermutation in their immunoglobulin genes, indicating that they have been generated through a germinal centre reaction to become memory cells. While naive MZ B cells produce low-affinity IgM antibodies, memory MZ B cells express high-affinity Ig molecules.
Marginal cost is the change of the total cost from an additional output [(n+1)th unit]. Therefore, (refer to "Average cost" labelled picture on the right side of the screen. Average cost. In this case, when the marginal cost of the (n+1)th unit is less than the average cost(n), the average cost (n+1) will get a smaller value than average cost(n).
Marginal analysis is a method to study the change of micro increment in economic operation by means of derivative and differential method, and to analyse the relationship between economic variables and the change process. Marginal "extra", namely, the meaning of "additional" refers to is on the edge of the "has been one of the last unit in ...
Marginal zone lymphoma (MZL) is a heterogeneous group of indolent B cell lymphomas that arise from the marginal zone of lymphoid tissues. [17] It accounts for 5–10% of all NHL cases, with an annual incidence of 0.4 to 1.0 per 100,000 in Western countries. [ 18 ]
