Total directional

There is no other means but to define, if neeessary, the total direct eorrela-tion funetion via the eommon Ornstein-Zernike equation... [Pg.196]

We apply the singlet theory for the density profile by using Eqs. (101) and (103) to describe the behavior of associating fluids close to a crystalline surface [120-122], First, we solve the multidensity OZ equation with the Percus-Yevick closure for the bulk partial correlation functions, and next calculate the total correlation function via Eq. (68) and the direct correlation function from Eq. (69). The bulk total direct correlation function is used next as an input to the singlet Percus-Yevick or singlet hypernetted chain equation, (6) or (7), to obtain the density profiles. The same approach can be used to study adsorption on crystalline surfaces as well as in pores with walls of crystalline symmetry. [Pg.207]

If the minimal number of operators necessary to run the plant is for example 10 in a 4 shift system all the year through, than there is a total of 40 operators on the payroll. At an average salary of 20,000 a year, the total direct costs for labour are 800,000. [Pg.259]

As part of the total direct costs we also have to consider costs made for supplies and expenses maintenance, 3% of total capital supplies, 25% of direct labour. These figures, calculated back to one kg of L-phenylalanine are given in Table 8.6. [Pg.260]

Plant overhead accounts for about 60% of total direct labour and is thus calculated to be 480,000 (see Table 8.6). [Pg.260]

Further detailed analyses of the ECA data have been extrapolated to USA national costs (Rice and Miller, 1998). It was calculated that the economic costs of mental disorders in 1990 in the USA totalled US 147.8 billion. Anxiety disorders were the most cosdy, amounting to 46.6 billion, just under a third of the total. Direct costs spent on mental health care totalled 67 billion, of which anxiety disorders accounted for only 11 billion (16.5%). Drug costs were 2191 million, of which anxiety disorders accounted for 1167 million—over half Morbidity costs—the value of goods and services not produced because of mental disorders — amounted to 63.1 billion, with anxiety disorders accounting for 34.2 billion, 54.2% of the total. This reflects the high prevalence of anxiety disorders in the community and the high associated rate of lost productivity. In contrast, patients with affective disorders appeared better able to function (Rice and Miller, 1995). In summary, anxiety disorders are common, disruptive and costly to society drug treatment is a substantial element of treatment costs (11%) compared with, say, schizophrenia (2.2%). [Pg.60]

Treating a condition is usually cheaper than not treating it (the offset effect). A Spanish study of panic disorder patients reported an offset effect of 14% following 12 months of drug treatment (Salvador-Carulla et al, 1995). Thus, the total direct costs of health-care use during the previous year and the year following diagnosis were US 29 000 and US 46 000 respectively, but the estimated... [Pg.60]

Increased total, direct, and indirect bilirubin concentrations indicate defects in transport, conjugation, or excretion of bilirubin. [Pg.328]

In the limit of total directional randomization, P will be equal to zero. [Pg.66]

The embodied labour values represent the total (direct and indirect) labourtime required to produce each unit of physical output. These embodied labour values have to be socially validated in their value-form as money. By setting prices equal to values, the embodied labour magnitude and the money value-form are assumed to be identical. [Pg.32]

The main thrust of the new interpretation is to provide a translation between total money value added (the money value of total net output, pQ) and total direct labour-time (IX). By defining the value of money (Am) as the ratio of total labour-time to total money value added,... [Pg.95]

Furthermore, a number of studies have shown that the direct mutagenicity of particles is primarily associated with particles having Dp < 2.5 /tm. For example, Viras and co-workers (1990) report that at two sites in Athens, Greece, 81 and 92% of the total direct activities (TA98 — S9) were associated with particles having Dp < 3.3 /r,m. Furthermore, 60 and 80%, respectively, were in submicron particles, Dp <1.0 gm. [Pg.488]

Figure 10.25 shows these mutagrams for the vapor and particle phases, respectively. Interestingly, the total direct mutagenicity of the vapor phase, 210 rev m-3, was actually greater than that of the particle phase, 160 rev m 3 furthermore, its mutagenicity profile was substantially different. Thus, fraction 4 is the major peak for the vapor-phase sample whereas most of the particle-phase mutagenicity is in the more polar peaks 6 and 7. Similar enhancements in the contributions of more polar species were reported for bioassay-directed fractionation of SRM 1649 urban air particulate matter (Schuetzle and Lewtas, 1986 Nishioka et al., 1988 ... [Pg.502]

Table 14.4 summarizes the estimated total direct radiative forcing calculated for the period from preindustrial times to 1992 for C02, CH4, N20, and O, (IPCC, 1996). The estimate for CH4 includes the effects due to its impacts on tropospheric ozone levels or on stratospheric water vapor, both of which are generated during the oxidation of methane. That shown for 03 is based on the assumption that its concentration increased from 25 to 50 ppb over the Northern Flemi-sphere. The total radiative forcing due to the increase in these four gases from preindustrial times to the present is estimated to be 2.57 W m 2. [Pg.785]

Source Agriculture is the main source, whereas the basic inorganic chemicals and fertilizer production activities are responsible for 29 and 25% of the total direct industrial releases of nitrogen and phosphorus, respectively, into water. [Pg.24]

The surface average diameter is always larger than the direct average of the diameters for a polydisperse system since the larger diameters contribute relatively more to the sum of the squares than they would if totaled directly. Example C. 1 illustrates such a calculation. [Pg.633]

The analysis shows that the maximum profit for the Georgian economy may be reached via the development of the South Caucasian Pipeline system. The total direct revenue in this case is calculated as the sum of capitalization of transit fees (corresponding to 5% of the transported gas) and incomes received because of difference between agreed special price for Georgia (55 /1000 cub. m) and the forecasted price on local market as shown in Figure 5 for the examined period (2020). [Pg.21]

Walsh and Engelhardt estimated the direct costs for insomnia in the United States to be 10.9 billion in 1990, whereas the National Commission on Sleep Disorders Research estimated the direct costs to be 15.4 billion in 1990 (61). Walsh and Engelhardt estimated in 1995 that the total direct costs increased to 13.9 billion. The costs were separated into health care services and substances used for insomnia. [Pg.220]

To account for the total directional scattering from a large sphere, effects of both diffraction and reflection must be considered. When a spherical particle is in the path of incident radiation, the diffracted intensity may be obtained from Babinet s principle, which states that the diffracted intensity is the same as that for a hole of the same diameter. The phase function for diffraction by a large sphere is given by [Van de Hulst, 1957]... [Pg.147]
