Final questions

Note that the system remains stable in all cases, as it should for a first or second order system. One final question Based on the design guidelines by which the system should respond faster than the process and the system should be slightly underdamped, what are the ranges of derivative and integral time constants that you would select for the PD, PI, and PID controllers And in what region are the desired closed-loop poles ... [Pg.249]

The final question we shall consider here has to do with the extrapolation of the solubility of hydrogen in silicon to lower temperatures. Extrapolation of a high-temperature Arrhenius line, e.g., from Fig. 11, would at best give an estimate of the equilibrium concentration of H°, or perhaps of all monatomic species, in intrinsic material the concentration of H2 complexes would not be properly allowed for, nor would the effects of Fermi-level shifts. Obviously the temperature dependence of the total dissolved hydrogen concentration in equilibrium with, say, H2 gas at one atmosphere, will depend on a number of parameters whose values are not yet adequately known the binding energy AE2 of two H° into H2 in the crystal, the locations of the hydrogen donor and acceptor levels eD, eA, respectively, etc. However, the uncertainties in such quantities are not so... [Pg.294]

Q. Thank you. Now my final question. In this Prosecution Affidavit 338, you deal with the knowledge and responsibility of the Vorstand, the technical committee, and the commercial committee. May I ask on what you base this opinion ... [Pg.308]

The final question in this section of the interview inquired into the respondents willingness to have a genetic test if the results were available to their life insurance company. Again, the likelihood of participation decreases with years of education and is significantly higher among racial/ ethnic minorities compared with whites. What is noteworthy here is the finding that respondents who have total family incomes above 50,000 are... [Pg.31]

In conclusion, and answering the final question, this research demonstrates that the developed 7-stage protocol can explicitly and pro-actively indicate safety risks and help organizations to direct their resources to improve safety, which includes their control structure (their normal way of working), effectively. [Pg.6]

The final question concerned the predicted thermal storage lifetime of the coating, which would probably be a good measure of stability lifetime of the hot-melt-coated particle. As shown in Fig. 4.28, the coating mixture was predicted to be thermally stable in dry air at 40°C for more than four years. [Pg.114]

The first four questions address substances that are reactive with air, water, or ordinary combustibles—materials that are almost certain to be in close proximity to the reactive substances. The next question addresses self-reactive materials. This is followed by a final question combined with a series of steps for addressing chemical incompatibility. [Pg.53]

Final question how big are the nucleic acids How many nucleotide units do we typically find in DNA or RNA The answer is enormously variable. There are small RNA molecules that contain 25 or fewer nucleotides there are also RNA molecules that contain thousands of nucleotides. But for really, really big molecules, we turn to DNA, which may have tens of thousands of nucleotides linked together Specific examples follow below but we need some additional insights first. [Pg.153]

From receipt of an application until a final decision on an application, a DSEB evaluator may request additional information or clarification from the sponsor under Section 31 of the Act. During the period from issuing a Section 31 letter and receipt of responses to all questions, the clock is stopped and the elapsed time is not counted towards the TGA s statutory evaluation time frames, if several Section 31 requests overlap, the periods are not additive but the clock remains stopped until the final question is answered. A sponsor is given a time frame in which a Section 31 request should be answered. Justification for an extension of time may be discussed with the evaluator, if a sponsor considers that a Section 31 request is unreasonable they can discuss this with the delegate who issued the request, if the sponsor is unable to resolve the matter with the delegate, it may seek review under an additional, non-statutory appeal mechanism by a three-member Standing Arbitration Committee (SAC). [Pg.664]

The final question asks about the validity of the conclusions drawn by the study authors. Were the conclusions based on some overall index or ratio of costs to consequences, and was the index interpreted intelligently Did the study authors provide benchmarks to aid in the interpretation of the study, and was the robustness of the conclusions discussed in light of results of the sensitivity and/or statistical analyses Was subgroup analysis undertaken where relevant Were the results compared with those of others who have investigated the same question Were the limitations of the study and the gen-eralisability of the results discussed Were other relevant factors in the decision to adopt the intervention discussed (e.g. distribution, ethics) And... [Pg.695]

Look at the last sentence and the final question How many people. .. To have the solution of the equation come out to be the final answer, you let the variable, x, be equal to the number of passengers now riding in the van. The cost per person now is 1 less than it used to be, so the equation you write will be something to the effect that 12 divided by the number of riders now is equal to 1 less than 12 divided by the number of riders that there used to be. Math speak is much easier to write ... [Pg.175]

Age Factor. A final question is the issue of age, which may also play a significant role. In addressing this factor, Stanley et al. ( 16) compared elderly (mean age = 69.2 5.3) with younger (mean age = 33.7 6.6) medical patients for capacity to consent. Although both groups tended to make reasonable decisions, the elderly patients demonstrated poorer comprehension for various elements of the informed consent process. Thus, special care must be taken to ensure that older patients comprehend sufficiently to give a valid consent. [Pg.29]

Above are presented the experimental observations regarding secondary IEs on acidity and basicity, with little discussion or speculation on the causes. The final question, addressed here, is the origin of those IEs. The interpretations proposed below are often reinforced with calculations or with other types of experimental data. [Pg.157]

To address the final question it is necessary to break down these broad requirements into the specific skills and the number of people with these skills that will be needed for each project For example, the synthetic chemistry requirement... [Pg.14]

Because of the intense interest in allometry, we should end this discussion with a final question Is there a universal biologically important principle underlying the 0.75 power law West et al. (2000) certainly believed there was such a principle when they initiated their search for an explanation for why b = 0.75 for SMR in so many organisms and so many functions. After reviewing current information on this question, however, we suspect that they answer may be no. In fact, from our analysis the thought arises that biologists and physiologists... [Pg.38]

The correct answer is (E). You need to consider the answers to three questions while working through this one. First of all, if an ice cube sits out at room temperature, is heat required to melt it If so, the process is endothermic (and Af F will be positive). The second question Is the water more disordered than the ice If so, the process increases the entropy (which will be positive). The final question Is the process spontaneous If so, the free energy is negative. [Pg.549]

The final question why the converged R S ratio of the B cyanoethyl group is not 25 25 but 20 30 must be explained. The reaction cavities for the B cyanoethyl groups in pip-1, pip-3, and pip-5 before and after the irradiation are shown in Fig. 11, in which each cavity is divided into two by the plane composed of the Co-C-C-N bonds. The volumes of the two parts were calculated. The left and right parts of the cavities before irradiation were 45 55, 56 44, and 63 37, respectively. These ratios became 48 52, 49 51, and 52 48, respectively after irradiation. These values are 50 50 within experimental error. This suggests that the inversion ratio of the B cyanoethyl group depends on the symmetry of the cavity. In other words, the inversion ratio is determined by the steric repulsion... [Pg.543]

Crestfallen, the witness left the dock. Dr. Vrba s initial questioning, cross-examination and final questioning filled 400 pages of transcripts (pp. 1244-1643). These pages could readily be used in an encyclopedia of law under a chapter on the detection of false witnesses. [Pg.139]

A final question to be addressed is that of the limits of the descriptor system with regard to the structures it can be applied to. In a stricter sense, it should be valid for all fullerenes and their derivatives having a cage framework that is unaltered with respect to the number of atoms and their coordination within the core. In practice, however, as various core-modified fullerenes have been synthesized,41 49 it may appear convenient to apply it to all compounds that are relatively closely related to the carbon spheres and to which fullerene nomenclature can be easily applied. [Pg.7]

This final question asks you to try and determine if a set of experimental data fits the terminal or penultimate model. For a copolymerization of A and B monomers (at low degrees of conversion) the following data were obtained. [Pg.165]

But I am not afraid to consider the final question as to whether, ultimately - in the great future - we can arrange the atoms the way we want the very atoms, all the way down What would happen if we could arrange the atoms one by one the way we want them (within reason, of course you can t put them so that they are chemically unstable, for example). [Pg.450]
