General resistance, definition

Ohm s law. V = IR, where /is the potential across a circuit element, / is the current through it, and R is its resistance. This is not a generally applicable definition of resistance. It is only applicable to ohmic resistors, those whose resistance R is constant over the range of interest and V obeys a strictly linear relation to /. 

The normal form of PrP has been referred to as either PrP - for PrP-cellular or PrP-sen, which designates its sensitivity to proteinase K The abnormal form of PrP has been referred to as either PrP for PrP-scrapie or PrP-res, which designates its partial resistance to proteinase K Since the terms PrP-sen and PrP-res reflect a general biochemical definition rather than a disease-specific phenotype, they will be used throughout this discussion. 

Resistance (R) - Electric potential difference divided by current when there is no electromotive force in the conductor. This definition applies to direct current. More generally, resistance is defined as the real part of impedance. [1]... 

The hardness of a body is understood to be the mechanical resistance of this body to its penetration by another. A generally valid definition of hardness suitable for all materials does not exist neither are there generally applicable test methods. The various hardness scales, however, can be roughly related to each other (Table 11-6). 

Occupational safety legislation and people in industry have traditional recognized the adverse role of the accident in the workplace and have accepted the need to identify causation for the purpose of avoiding repetition. However, the statutes have generally resisted an attempt to provide a workable definition of an accident or have defined accident in terms of an outcome, i.e. injury, near miss, dangerous occrrrrence, incident, etc.

Rejection Rejection is defined in Background and Definitions. The highest-rejection membranes are those designed for single-pass production of potable water from the sea. The generally accepted criterion is 99.4 percent rejection of NaCl. Some membranes, notably cellulose triacetate fibers are rated even higher. A whole range of membranes is available as rejection requirements ease, and membranes with excellent chlorine resistance and hydrolytic stability can be made with salt rejection over 90 percent. 

Table IV summarizes the results for the resist screening studies at SSRL. The resist candidates generally exhibited good sensitivity, Dg 5 < 50 mJ/cm2, and contrast, 7 = 1.5. Definitive conclusions regarding the effect of structure on sensitivity are made difficult by the fact that polymer molecular weight and poly-dispersity varied considerably from sample to sample and, since we found a very strong dependence of Dg 5 on these parameters, specific structural effects are obscured. Several generalizations can be made, however.

In short, small but definite frequency dependence upon measured resistance is generally observed and the problem becomes one of obtaining the correct ohmic resistance of the solution by an extrapolation procedure. (See discussion of extrapolation procedures below.)... 

There are limited data on the chemical resistance of various oxide materials in the literature (Samsonov 1982, Ryshkewitch and Richerson 1985). Furthermore, many of the studies are concerned with solid, nonporous materials. Nevertheless, these may provide an indication of the general trends. Until a definitive and quantitative database of chemical stability of various inorganic membranes becomes available, some simple dissolution-type test methods using membrane samples may be employed on a comparative basis to estimate the extent of attack by a chemical under the application conditions. An example of such a simple test is given below.
