The value of the compresjiibility of oil is a function of the amount of dissolved gas, but is in the order of 10 x 10" psi" By comparison, typical water and gas compressibilities are 4x10" psi" and 500 x 10" psi" respectively. Above the bubble point in an oil reservoir the compressibility of the oil is a major determinant of how the pressure declines for a given change in volume (brought about by a withdrawal of reservoir fluid during production). [Pg.109]

At least one hole near the perimeter of each plate connects the flow ch annels from one side of the plate to the other. The membrane is sealed around the hole to isolate the permeate from the concentrate. Permeate collects in a drain grid behind the membrane and exits from a withdrawal port on the frame perimeter. [Pg.302]

Mutual Exclusion (MUTEX). The idea of multiple entities all working on the same piece of work raises this issue of coordination and communication among the individual processes. A weU-known example from banking is instmctive. Consider two bank tellers simultaneously performing withdrawals from the same bank account. Both read the account balance and determine that the balance is 100, and so a withdrawal of 100 is allowed. Both then withdraw 100 from the account. Clearly this process needs some means by which the actions of the independent processes can be synchronized and coordinated. [Pg.94]

Withdrawal of a draw-out circuit breaker or a withdrawable switch or contactor will not be possible unless they are in an OFF position. [Pg.377]

Operation of withdrawable equipment, such as a breaker or components on a withdrawable chassis, will not be possible unless it is in serv ice. test, isolated or totally removed positions. [Pg.377]

Deshielding (Section 13.2) An effect observed in NMR that causes a nucleus to absorb downfield (to the left) of tetramethylsilane (TMS) standard. Deshielding is caused by a withdrawal of electron density from the nucleus. [Pg.1239]

Table 9 shows the PP MO results for this interesting series of highly strained three-membered cyclic molecules. Here a detailed comparison is possible with the best results of an all-electron study, including d functions10 (also reported in Table 9). An analysis of this table reveals how all trends in population analysis, both in charges and overlap populations, are the same in the AE + d and in the simple PP calculations, with very few and very minor exceptions. PP predicts a charge donation to the aliphatic groups, while AE predicts a withdrawal, mainly due to the availability of d orbitals on sulphur, which can allocate extra electronic charge. As outlined in the general notes on population analysis (Section III.D) comparisons should be carried out on a relative basis and,...

A rebound sleep disturbance has been found after only 7—10 days of treatment with therapeutic doses of triazolam (Greenblatt et al. 1987). Others have described a withdrawal syndrome after substitution of a short-acting benzodiazepine for a long-acting benzodiazepine (Conell and Berhn 1983). Rebound insomnia may occur with zolpidem. [Pg.129]

Typically, funding to embark on information and/or knowledge management initiatives within the life sciences only occurs after a serious failure within the business, such as a project failure or a withdrawal of a medicine from the market. Recently, COX-2 programs across the industry are under close scrutiny since the highly publicized withdrawal of Vioxx [10]. Of course, there has been no withdrawal of aspirin, paracetamol, alcohol, or tobacco products, which are well known as toxic. [Pg.173]

SSRIs are the drugs of choice for PD. All SSRIs have demonstrated effectiveness in controlled trials, with 60% to 80% of patients achieving a panic-free state.28,48,49 With similar efficacy reported and no trials comparing SSRIs with other SSRIs, selection generally is based on pharmacokinetics, drug interactions, side effects, and cost differences (see Chap. 35 for more discussion). The most common side effects of SSRIs include headaches, irritability, nausea and other gastrointestinal complaints, insomnia, sexual dysfunction, increased anxiety, drowsiness, and tremor.49 SSRIs should not be discontinued abruptly to avoid a withdrawal syndrome characterized by dysphoric mood, irritability, and agitation. [Pg.615]

The answer is c. (Hardman, pp 574—575.) Phencyclidine is a hallucinogenic compound with no opioid activity Its mechanism of action is amphetamine-like. A withdrawal syndrome has not been described for this drug in human subjects. In overdose, the treatment of choice for the psychotic activity is the antipsychotic drug haloperidol. [Pg.160]

The hydrological simulations for the future time-slice 2071-2100 were performed using the bias-corrected daily time series derived from the two different climate scenarios described in Table 4 as external forcing, and the hydrological parameters obtained during the calibration and verification period described in Sect. 6.1. One operational modification was made to the simulation of subcatchment 057, where a withdrawal corresponding to the Ebro-Besaya water transfer, described in Sect. 6.1, was allowed to remove water outside the catchment. This water transfer was introduced only for the simulations of the future scenarios, while the... [Pg.68]

Chronic exposure is not usually associated with a withdrawal syndrome, but sudden discontinuation by heavy users can cause a withdrawal syndrome. [Pg.841]

A sequence constraint may govern actions, stating the possible sequences it may be expressed in the form of a state chart. Of all possible sequences of finer actions, only some may constitute an occurrence of the abstract action for example, the card reader and ATM keys can always be used, but only some sequences constitute a withdraw action. An action refinement sequence relates finer sequences to specific abstract actions, and can be expressed in the form of a state chart. [Pg.601]

For several reasons, ranges of pigments have been rationalized in recent years, causing a withdrawal of a considerable number of pigments from the market. The rationale behind the removal of these pigments, when known to us, is given. Since these brands will still be used for some years, for example in automotive repair finishes, we have continued to describe their properties in the new edition. [Pg.666]

Corresponding to this valence bond view is a molecular orbital picture. The three cr-orbitals of a CH3 group are regarded as a basis from which three group orbitals may be constructed. One of the possible combinations of the tr-orbitals has the same local symmetry as the vacant p-orbital on the cationic centre, and hence may overlap with it. Therefore, a withdrawal of electrons from the methyl group can take place. The orbital from which electron density... [Pg.198]
