Materials that have the abiUty to dissipate a charged formed, by any means including tribocharging and induction, on the material are referred to as static dissipative. There is a correlation between static dissipation and surface resistance. EIA-541 currently defines the static dissipative range as 10 to 10 ... 

An electron in a circular orbit with an angular velocity o) passes each point in the orbit m/2jr times per second. This electronic motion constitutes an electric current /, defined as the amount of charge passing a given point per second, so that... 

Confirmatory methods must be sufficiently robust to accurately verity the structure of the analyte. For the US FDA, the validation procedure for confirmatory methods is currently defined by Sphon. Validation criteria include reproducible chromatographic separation, ions chosen to be characteristic of the molecule. 

Osteoporosis is currently defined as a skeletal disorder characterized by compromised bone strength predisposing to an increased risk of fracture. Bone strength reflects the integration of two main features bone density and bone quality (NIH Consensus 2001). Thus, osteoporosis is a debilitating condition of the skeleton that propends to fractures and is associated with advanced age. The disease has a high prevalence in western countries, as it is a condition associated with advanced age, and it is on the rise since fife expectancy has risen dramatically in the last several decades. It is, therefore, a major public health problem because it not only induces morbidity (fractures and chronic sequelae) with a substantial impact on health-related quality of life, but is also associated with increased mortality (Badia et al. 2001, 2004). 

CRT is now recommended for patients with LVEF less than or equal to 35%, sinus rhythm, and NYHA functional class III or ambulatory class IV symptoms despite recommended, optimal medical therapy and who have cardiac dyssynchrony, which is currently defined as a QRS duration greater than 0.12 ms, unless contraindicated. To date, over 4,000 patients have been studied in randomized clinical trials of CRT. A recent evaluation of complications from those studies suggest a risk of implant mortality of 0.4%, failure to implant a functioning LV lead in 10%, lead malfunction or dislodgement in 8.5%, and pacemaker infection in 1.4% [123]. 

Fig. 14.2. Questions regarding mechanism of action of praziquantel. Praziquantel affects Ca2+ homeostasis in the adult worm, which results in a cascade of events that ultimately lead to elimination of parasites from the host. Entities mediating these effects and their location are not currently defined and are presented within a black box . Possible sites of action are shown. Figure updated from Day etal. (1992) and Harder (2002).

The potential window over which the electrolyte is electrochemically stable may be estimated using a polarizable (blocking) electrode, such as platinum. The current is monitored as a function of the electrode potential, and the zero-current region (or nearly zero-current) defines the domain of electrochemical stability of the electrolyte. Of course, this potential range will depend mainly on the nature and the surface of the electrode (roughness).

Consider the driving system shown in Fig. 15a. A battery is connected to a resistor. Convention states that positive current (defined as the flow of positive charge) leaves the positive terminal of a discharging battery and enters the positive terminal of a resistor. A voltmeter would read a positive value if its positive lead were connected to the positive end of the resistor (or battery) and its negative lead attached to the negative side of the resistor. 

It is important to remember that the measured current is the applied current, defined as... 

The prospective short-circuit current defines the short-circuit current which can be expected in case of replacing the short-circuit point by an (ideal) electrical connection with zero impedance. Due to a short-circuit point impedance greater than zero in practice, the prospective short-circuit current indicates the upper limit of a short-circuit current in a defined grid at a given point. 

This volume of the Handbook of Neurochemistry deals with chemical mechanisms in the nervous systems of sick people. It is intentionally not a catalogue of neurochemical phenomena in specific diseases, as those entities are currently defined. Thus, there are no chapters on the Neurochemistry of Depression or Neurochemistry of Stroke. The choice to focus on mechanisms rather than on diseases deserves explication.
