The detection sensitivity of radiography is related among others to the properties and quality of industrial x-ray film systems. Changes of the products, variations due to different emulsions and combinations of products of different manufacturers can influence the decisive properties of film systems as classified in EN 584-1.To ensure the quality of industrial x-ray film systems a system for quality assurance open to all interested parties is proposed which is based on periodical round robin tests and quality controls of the manufacturer or an independent third party institution. [Pg.555]

Just as one may wish to specify the temperature in a molecular dynamics simulation, so may be desired to maintain the system at a constant pressure. This enables the behavior of the system to be explored as a function of the pressure, enabling one to study phenomer such as the onset of pressure-induced phase transitions. Many experimental measuremen are made under conditions of constant temperature and pressure, and so simulations in tl isothermal-isobaric ensemble are most directly relevant to experimental data. Certai structural rearrangements may be achieved more easily in an isobaric simulation than i a simulation at constant volume. Constant pressure conditions may also be importai when the number of particles in the system changes (as in some of the test particle methoc for calculating free energies and chemical potentials see Section 8.9). [Pg.401]

Draw bond order and free valency index diagrams for the butadienyl system. Write a counter into program MOBAS to detemiine how many iterations are executed in solving for the allyl system. The number is not the same for all computers or operating systems. Change the convergence criterion (statement 300) to several different values and determine the number of iterations for each. [Pg.230]

As the mechanical integrity of the pump system changes, the amplitude of vibration levels change. In some cases, in order to identify the source of vibration, pump speed may have to be varied, as these problems are frequency- or resonance-dependent. Pump impeller imbalance and cavitation are related to this category. Table 10-11 classifies different types of pump-related problems, their possible causes and corrective actions. [Pg.915]

The general case is that of steady-state flow, and the thermal conductivity factor is a function of the temperature. In the unsteady state the temperature of the system changes with time, and energy is stored in the system or released from the system reduced. The storage capacity is... [Pg.110]

If you decide to conduct a PSM user survey, keep in mind that it s essential to provide feedback to respondents on the survey results and the action plans or system changes (if any) that result. If users see that their input has value and impact, they are more likely to develop the sense of ownership that will help determine the long-term success of the PSM system. [Pg.184]

A As z company we have adopted ISO 9000 and today most of our staff are familiar with this system. Changing to a different system would cause confusion. We did consider adopting ISO 14000, the new environmental standard. However, we have no experience with ISO 14000, and I consider it prudent to stick with something we already know. The integration itself will introduce enough changes in the way we work. We may revisit this decision is a few years when some of our competitors have tried out ISO 14000 ... [Pg.42]

FPN) Hazards often occur because of overloading of wiring systems by methods or usage not in conformity with this Code. This occurs because initial wiring did not provide for increases in the use of electricity. An initial adequate installation and reasonable provisions for system changes will provide for future increases in the use of electricity. [Pg.634]

Chlorinated solvents, when allowed to combine with minute amounts of water often found in operating hydraulic systems, change chemically into hydrochloric acids. These acids then attack internal metallic surfaces in the system, particularly those that are ferrous, and produce a severe rust-like corrosion. [Pg.603]

As pointed out earlier, the equilibrium constant of a system changes with temperature. The form of the equation relating K to T is a familiar one, similar to the Clausius-Clapeyron equation (Chapter 9) and the Arrhenius equation (Chapter 11). This one is called the van t Hoff equation, honoring Jacobus van t Hoff (1852-1911), who was the first to use the equilibrium constant, K. Coincidentally, van t Hoff was a good friend of Arrhenius. The equation is... [Pg.341]

Another potential complication can occur if the responsiveness of the receptor system changes temporally. This can happen if the receptor (or host system, or both) demonstrates desensitization (tachyphylaxis) to drug stimulation (see Chapter 2). There are numerous systems where constant stimulation with a drug does not lead to a constant steady-state response. Rather, a fade of the response occurs. This can be due to depletion of a cofactor in the system producing the cellular response or a conformational change in the receptor protein. Such phenomena protect against overactive stimulation of... [Pg.87]

A potential pitfall with stop-time experiments comes with temporal instability of responses. When a steady-state sustained response is observed with time, then a linear portion of the production of reporter can be found (see Figure 5.15b). However, if there is desensitization or any other process that makes the temporal responsiveness of the system change the area under the curve will not assume the linear character seen with sustained equilibrium reactions. For example, Figure 5.16 shows a case where the production of cyclic AMP with time is transient. Under these circumstances, the area under the curve does not assume linearity. Moreover, if the desensitization is linked to the strength of signal (i.e., becomes more prominent at higher stimulations) the dose-response relationship may be lost. Figure 5.16 shows a stop-time reaction dose-response curve to a temporally stable system and a temporally unstable system where the desensitization is linked to the... [Pg.89]

One of the main methods for improving the mechanical properties of linear polymers is their drawing that can be uniaxial (fibres), biaxial (films), planar symmetrical (films-membranes) etc. As a result of polymer deformation, the system changes into the oriented state fixed by crystallization. [Pg.211]

The operator bx annihilates a particle from the A-state, while the operator 6J creates a particle in the A-state, leaving the other states unchanged the total population of the system changes by unity in each case. The numerical factors are chosen so that the product of the two operators in the appropriate order is given by... [Pg.449]
