Simplified Acquisition Procedures (SAP) are a set of streamlined procedures for government procurement in the United States that reduce the administrative burden of awarding procurements below a threshold value, which, as of 2023, is $250,000. [1] The procedures are described in 48 CFR 13.
Certified cost or pricing data may not be obtained for acquisitions at or below the simplified acquisition threshold. [3] Other exceptions are stated in FAR 15.403-1(b) or may be adopted under a waiver requested by the contracting officer in exceptional circumstances. If certified cost or pricing data has been requested by the Government and ...
If FAR Part 13, simplified acquisition is used, then a contracting officer can select from a range of processes including Government Purchase Card (GPC) for purchases under the micro-purchase threshold (see definition section of FAR for current value (for example, in U.S., it is currently $2,500), simplified acquisition threshold (see FAR ...
In electromagnetism, current density is the amount of charge per unit time that flows through a unit area of a chosen cross section. [1] The current density vector is defined as a vector whose magnitude is the electric current per cross-sectional area at a given point in space, its direction being that of the motion of the positive charges at this point.
The electric current density J A equals the charge q A of the ion multiplied by the flux j A = Current density has units of (Amperes/m 2). Molar flux has units of (mol/(s m 2)). Thus, to get current density from molar flux one needs to multiply by Faraday's constant F (Coulombs/mol).
The relationship between the sum of the current sources and sinks and the voltage measured by the microelectrode probe may be calculated analytically if it is assumed that the quasi-static assumption holds, that the medium is spherically symmetric, homogeneous, isotropic, and infinite, and if the current source or sink is modeled as a point ...
the total electric current density (total current per unit area), J. The universal constants appearing in the equations (the first two ones explicitly only in the SI formulation) are: the permittivity of free space, ε 0, and; the permeability of free space, μ 0, and; the speed of light, = /
The thermal current density is the flux per unit time of thermal energy across a unit area perpendicular to the flow. It is proportional to the temperature gradient. j q = − κ ∇ T {\displaystyle \mathbf {j} _{q}=-\kappa \nabla T} where κ {\displaystyle \kappa } is the thermal conductivity.
