The disturbances because of lightning surges (LS/220 cases) and main-circuit switching surges (SS/47) in Table 6.1 were found in the following manner  [Pg.395]


For same conditions as (1.) Some data are reported as individual gas or liquid film coefficients or transfer unit heights. However, it is often possible to use it as overall data if the conditions are understood. [Pg.350]

From the overall data, it is becoming inaeasingly apparent that astrocytes, by releasing chemical transmitters (the so called gliotrasmitters , Bezzi and Volterra 2001), now appears to be aitically implicated in rapid conununication systems in the brain. [Pg.277]

Guidelines for acceptability of NADA and non-NADA methods are the same. For the determinative procedure, the criteria described in Method Criteria for accuracy and precision are used to evaluate data generated at participating laboratories. There are no criteria for accuracy in the analysis of the incurred residue samples however, the overall data set is reviewed to see if there is general agreement between results obtained by contract laboratories and relative to the levels reported in the sponsor s laboratory. [Pg.93]

Fig. 9.6. Relative risk ( 95% confidence intervals) for any cardiovascular event in the group treated with raloxifene or placebo. The information was obtained from the subgroup of women at increased cardiovascular risk in the MORE study. The overall data seem to favor raloxifene, but this effect is clearer when women were grouped according to their risk as assessed by the previously defined severity score (from Barrett-Connor et al. 2002)...

During a recent expedition in the Indian Ocean, as part of the WOCE Hydro-graphic Program, members of the U.S. DOE C02 Survey Science Team used these reference materials extensively for the quality control of measurements of total DIC and total alkalinity. Two manuscripts detailing the results of these measurements on reference materials were published describing the C02 measurements made on that expedition and how reference materials were used to assess the overall data quality (Johnson et al., 1998 Millero et al., 1998). [Pg.41]

The LC control software, either stand-alone or as part of an overall data-handling system, should be tested by means of a separate OQ protocol. This protocol only needs to address the communica-tions/control integrity of the hardware (e.g., setting up a run/sequence with the proper instrument parameters, the ability to start and stop the pump, etc.). It should cover all the required instrument control functions listed as part of the protocol s functional specifications. It does not need to include specific hardware performance testing, such as linearity or flow rate. The latter tests are performed separately, as part of the individual hardware validation described below. [Pg.310]

In the directly acquired dimension the spectral window can be opened up to cover all frequencies of interest on both sides of the carrier with a proportional increase in the overall data size. As an alternative, it may be sufficient to open the (audio)filters to allow signals to alias to empty regions (if any) with no intensity loss. Carrier shift using time domain tools in data processing can be applied to restore a more convenient arrangement of the spectrum [10]. [Pg.193]

A common problem experienced under the current automation paradigm, with the demand for greater results in shorter iteration cycles (1-2 weeks), is that screeners are required to collect data from several single assay workstations, often run on different software platforms. With the demand for results on more compounds per week, the screeners must process more samples through the assays, each with fewer data points and replicates. This trade off in quality for quantity can result in lower overall data fidelity. [Pg.10]

After a review of the voluminous literature, this distinguished panel concluded that ADHD is one of the best researched disorders in medicine in fact, the overall data on its validity are far more compelling than those for many other medical conditions. They also concluded that there was little evidence of widespread overdiagnosis or misdiagnosis of ADHD or of widespread overprescription of stimulants by physicians. [Pg.460]

The simplest case, that of two large infrared lines, is shown in Fig. 31(a). A smooth curve was fitted to the base line as shown. A spline-fitting computer program developed by De Boor (1978) was used to obtain this fit very conveniently. After the fit was obtained, the data were adjusted to a flat base line, as shown in Fig. 31(b), and the data field was extended by padding with zeros to yield an overall data field of 28 = 256 points. Taking the Fourier transform, we obtained the interferogram function shown in Fig. 32. (Even though it was not obtained directly from the interferometer as recorded... [Pg.317]

I shall conclude this section with a few remarks on practical restoration with the DFT. To take the fullest advantage of the computational speed afforded by the FFT, the overall data field is usually composed of a number of data points given by 2 raised to some integral power. The data are usually... [Pg.322]

Another useful method for sample selection is cluster analysis-based selection.3 4,67 in this method, it is typical to start with a compressed PCA representation of the calibration data. An unsupervised cluster analysis (Section 8.6.3.1) is then performed, where the algorithm is terminated after a specific number of clusters are determined. Then, a single sample is selected from each of the clusters, as its representative in the final calibration data set. This cluster-wise selection is often done on the basis of the maximum distance from the overall data mean, but it can also be done using each of the cluster means instead. [Pg.313]

The experimental determination of T, yu and xt is actually redundant. However, the equation corresponding to Equation (10.70) involves the partial molar entropies of the components in the two phases. In many cases the values of these quantities are not known. Therefore, a test of the thermodynamic consistency of each experimental point generally cannot be made, neither can the value of one of the three quantities T,yu and xt be calculated when the other two are measured. The test for the consistency of the overall data according to Equation (10.78) can be made when the isothermal values of both A i[T0, P, x] and Anf[T0> P> X1 have been determined. [Pg.254]

Representativeness is a measure of how well the overall data collection design, which includes the sampling design and the analysis, represents a characteristic of a population and the environmental condition at the site. This is the ultimate... [Pg.42]

An example of a functional and visualization analysis is provided here based on the author-generated L. monocytogenes growth phase datasets (shown in Figures 2-4). The overall data including individual biological replicates, generated in two separate sessions, are visualized as a multidimensional... [Pg.182]

Thus, even though the official overall data on Vin Santo are lacking, it is however estimated that to date, the production for Tuscany far outweighs that for the rest of Italy, as it represents almost all of the commercial production of Vin Santo. [Pg.67]

This last point is very important in two ways. First, throughout this book, the importance of optimum quality data is emphasized many times. In most cases, this comment is associated with acquiring the data, for example, measuring blood pressure as accurately as possible. However, since all of these data are entered into databases, data entry must be accurate A correct measurement that is stored incorrectly immediately lessens the quality of the overall data. Sometimes data are transferred from a measurement device electronically to the database, and sometimes data are manually entered into the database. Procedures to ensure accuracy, correctness, and completeness of data transfer are an essential part of data recording and management. Second, the storage of sensitive data (personal, medical) and proprietary data requires additional considerations to ensure that these data do not become accessible and available to unauthorized users. [Pg.76]

The effect of rHuKGF on the proliferation rate of 41 tumor lines was assessed as well as the effect on the growth of subcutaneous receptor positive human tumor xenografts in athymic mice. One tumor showed a statistically significant positive. The overall data to predict potential for tumor promotion in humans were deemed questionable. [Pg.461]
