Working capacity potential

The decreased work capacity of the in-farcted myocardium leads to a reduction in stroke volume (SV) and hence cardiac output (CO). The fall in blood pressure (RR) triggers reflex activation of the sympathetic system. The resultant stimulation of cardiac 3-adreno-ceptors elicits an increase in both heart rate and force of systolic contraction, which, in conjunction with an a-adren-oceptor-mediated increase in peripheral resistance, leads to a compensatory rise in blood pressure. In ATP-depleted cells in the infarct border zone, resting membrane potential declines with a concomitant increase in excitability that may be further exacerbated by activation of p-adrenoceptors. Together, both processes promote the risk of fatal ventricular arrhythmias. As a consequence of local ischemia, extracellular concentrations of H+ and K+ rise in the affected region, leading to excitation of nociceptive nerve fibers. The resultant sensation of pain, typically experienced by the patient as annihilating, reinforces sympathetic activation. [Pg.310]

The rotor is very flexible regarding batch size. Minimum batch size may be as low as 1/8 of working capacity. However, when applying films, the batch size should be selected such that the nozzle is immersed below the surface of the bed. This minimizes the potential that the high velocity atomization air will not blow some coating droplets through the bed where they may be spray dried and collected in the filter. [Pg.370]

Describe the relationship between stability, capacity to do work, and potential energy. [Pg.274]

In this work, the main aim has been to determine the steady-state behaviour behaviour by measuring the current-potential curve. In general, the steady state is the most important characteristic of an electrode reaction. Fortunately, most known electrochemical reactions have a steady state and are variations of the redox type of reaction. As shown above, the steady current-potential curve can be exactly interpreted for redox reactions. In order carry out a complete analysis, it is essential to measure the components of the steady state by impedance-potential measurements. In addition, impedance delivers information about the charging processes as they appear in the high-frequency double layer capacity-potential curve. This last parameter is the parameter which should connect electrochemistry and surface science. The unfortunate fact is that it is still not very well understood. [Pg.468]

The electrochemical behaviour of stainless steel has not been worked out completely, although the measured data are available. However, one aspect of the behaviour, based on the measured double layer capacity data, seems to be susceptible to interpretation. The capacity-potential curves are determined by the state of the metal surface and by the ionic environment. In this work, it has been assumed that the ionic environment is a constant. This means that the double layer capacity-potential curves should reflect the nature of the metal surface just as, say, an electron energy spectrum in surface science. Stainless steel has a complicated electrochemical behaviour. In previous work [22] an attempt has been made to compare the double layer capacity curves measured during dissolution and passivation of the stainless steel with that of the pure components. It seems that all the data in the high frequency regime can be fitted to eqn. (70) with the Warburg coefficient set equal to zero. [Pg.475]

As was described above, Panossian et al. [57] demonstrated the adaptogenic activity of Bryonia alba roots in preclinical and clinical trials. The same authors [75] studied the potential mechanism responsible for these adaptogenic effects, focusing on the potential activity of cucurbitacin R-diglucoside, one of the constituents of the active extract. This compound had previously been found to increase the working capacity of mice, and also to increase the survival of mice infected with Staphylococcus aureus as well as that of X-ray irradiated rats. It also reduced stomach ulcers in immobilized rats [75]. [Pg.456]

The work capacity and the related damage increase following the potential capacity and specific volume become larger. When the explosive properties and packed mass are given, the effect action distance is related with the geometry and detonation methods. [Pg.76]

Since the mechanical work on the surroundings is performed by gaseous products on account of the thermal energy liberated during the explosive process, the total thermal energy liberated can be taken approximately as the measure of working capacity-performance potential of an explosive ... [Pg.166]

The company will need to manage three groups of suppliers if the phase-out option is chosen. Suppliers of components that are not used in the new product must draw down their capacity or look for new customers. As these suppliers are negatively impacted, the company can explore opportunities to transition them to supplying some of the components of the new product. Suppliers of common components must increase capacity immediately, and then reduce it gradually as the current product phases out, and reach a steady state when only the new product is in production. Finally, new suppliers must be sourced for components unique to the new product. As new specialized capacity may be needed, the company would need to start working with potential suppliers much earlier than when the new product is introduced. [Pg.73]

Energy The capacity of a body for doing work. Mechanical energy may be either potential (by virtue of the body s position), or kinetic (by virtue of its motion). [Pg.1434]

Energy is the capacity to do work. Potential energy is the energy possessed by an object as a result of its position. Heat, another form of energy, ran be thought of in molecular terms as frictional losses of the uncoordinated motion of molecules. [Pg.807]
