At the present time, the exponent y has not been measured for a polymer solution and a direct measurement would be very difficult (see Section 1.2). However, we may hope to obtain y indirectly by measuring 9. For this purpose, one would use a dilute solution of polymers with marked end points. These [Pg.571]

Incidentally, we note that the integral which appears in (13.1.28) can be easily calculated (see Appendix M). One finds [Pg.573]

Conversely, such a dependence for large values of qX, implies that P(r) has a singularity of type (13.1.122). [Pg.573]


Several laboratories therefore intend to measure profiles of these isotopes on ice cores drilled in polar ice caps. The new technique also makes possible measurements of the 14C in the C02 occluded in about 30 kg of ice. From the 14C measurements again twofold information is expected ... [Pg.46]

All the possible measures of a given set of variables in all the possible subjects that exist is termed the population for those variables. Such a population of variables cannot be truly measured for example, one would have to obtain, treat and measure the weights of all the Fischer-344 rats that were, are, or ever will be. Instead, we deal with a representative group, a sample. If our sample of data is appropriately collected and of sufficient size, it serves to provide good estimates of the characteristics of the parent population from which it was drawn. [Pg.866]

Providing a more formal analysis, several objective measures to rank the parameters according to their impact on the stability can be utilized. Possible measures of dependency are ... [Pg.225]

Obviously the percentage of the islet tissue would be only one factor the total size of the pancreas might be another (65 to 160 gm.) and the specific activity of the islet tissue another. The total number of islets constitutes a possible measure of the ability to produce insulin. This number is estimated to vary normally from 200,000 to 2,500,000.15... [Pg.118]

Since all the m /2 have values between 0 and 1, there is another possible measurement of the correlation strength ... [Pg.515]

A great advantage of this type of system is that it makes possible measurements of relatively small matrix elements such as SX4 the signal can be amphfied as necessary because only one component is proportional to SX4. NormaUzation by Sxx, which is done electronically, ehminates fluctuations in particle number density and in the Hght source. If Sx, is desired, the electronic servo can be turned off and the instrument used in the conventional way. [Pg.418]

One possible measure of algorithmic complexity is program size. Such a measure is related to the inherent simplicity or complexity of a method. This measure is static it is independent of the size or structure of the particular input data. Some other possible measures are dynamic they measure the amount of a resource used by the method as a function of the size of the input data. Typical dynamic measures are running time and storage space. [Pg.13]

Development of a comprehensive and risk-based hazardous waste classification system requires assumptions about the measure or measures of response (adverse health effects) from exposure to radionuclides and hazardous chemicals that should be used in classifying waste. Possible measures of response discussed in Section 3.2.3 include fatalities, incidence, or some combination of the two, such as total detriment (ICRP, 1991). The following sections discuss the measures of response from exposure to hazardous subtances that... [Pg.258]

The minimum concentration required to eliminate the catalytic activity is one possible measure of the sensitivity of a catalyst to a poison. Sensitivity to poisoning is most properly defined by the amount, np, of the poison adsorbed on a unit amount of catalysts which causes a given fractional decrease of the catalytic activity (a = (a0 - ap)/a0), where aQ and ap are the activities in the absence or presence of poison, respectively) ot/rtp is a measure of the sensitivity to poisoning. One may also use the ratio of a to the concentration cp of the poison in the feed, namely a/cp, but this is less precise, as this depends on the adsorption coefficient of the poison. [Pg.570]

The development of biophysical techniques to make possible measurements of single ion channels in membrane bilayers has been fundamental to the advances in the understanding of how natural ionophores, particularly ion channel proteins, operate at the molecular level. The two principal techniques are the planar lipid... [Pg.8]

Our analysis led eventually to the conclusion that impact sensitivity can be related to this characteristic imbalance between the larger Vs+ and the smaller Vs [89]. There are of course a variety of possible measures of such imbalance, including the quantity v, defined by eq. (6), which we have used... [Pg.357]

The induction of HO activity by Tween-80 was not known, yet. Because of the application of Tween-80 in food processing, a mechanism of HO induction by damaging cells seems to be improperly. For sure results, this experiment should be repeated. If it is possible, measurements of HO activity after treatment with ANIT (without Tween-80) and C0CI2 + Tween-80 should be done. [Pg.81]

This is a surface vibrational spectroscopic technique that involves the irradiation of the adsorbate-metal interface with a beam of low-energy (2 to 10 eV) electrons and the measurement of the energies of the backscattered electrons energy losses below 0.5 eV are due mainly to inelastic interactions with metal-surface phonons and adsorbate vibrational excitations. The extremely high sensitivity of HREELS makes possible measurements of adsor-... [Pg.280]

Another possible measure of spectral dissimilarity, the Euclidean distance e between the tips of the two vectors, as shown in Fig. 2, can also be related to sine and cosine ... [Pg.1118]

The Gaussian distribution has a symmetrical, bell shape and is sufficiently characterized by its mean (/jl) and variance (cr2). Its standard deviation (cr) is the square root of the variance. The symbols pi and cr refer to the mean and standard deviation of a population (i.e., the set of all possible measurements of a particular quantity). In practice, /x, and cr often are not known because a population is too large to sample in its entirety. A subset of measurements of a particular quantity represents a sample of a population. If the sample is drawn from a normal population, the parameters characterizing the sample distribution are the sample mean of the measurements or observations (y) and the sample standard deviation (s). Both of these parameters are calculated based on the values of the sample observations and the number of observations,... [Pg.37]

UVA lS-spectroscopy is commonly used in the quality control laboratories of the flavour industry particularly for those products where colour characteristics are important. The possible measurement of the absorption or transmission of the samples in wavelength maxima as well as the intake of a spectrum over the entire wavelength area between 250-800 nm is important for the routine check of colour identity. By constant measuring parameters (cuvette, dilution, etc.) exact evidence of the colour intensity can be established. This analysis is very important for coloured flavouring preparations, fruit- and plant extracts or essential oils with colouring properties, as well as for testing for the presence of non permitted colouring materials [1],... [Pg.587]
