Functional effects

In order to function effectively, the organisational structure should make the required flow of information for field development and management as easy as possible. For example, in trying to co-ordinate daily operations, information is required on... [Pg.347]

The preparation of flocked fabric using acryflc adhesives is detailed in Reference 198. In flocking, cut fibers are bonded to an adhesive-coated fabric to achieve both a decorative and a functional effect. Acrylics can be tailored to provide the unique balance between softness and durability required for this... [Pg.171]

Fat Replacers. Eat has a ubiquitous presence in food and provides unique flavor, mouthfeel, and functional effects. At 9 kcal/g (38 kj/g), fat can be a principal source of dietary calories, and excessive consumption has been correlated with the incidence of chronic disease and morbidity. Health officials have strongly urged consumers to reduce fat intake to no more than 30% of daily calories. Therefore, a demand for low fat versions of high fat foods has developed. Eat replacers (qv) are the ingredients that make these foods possible. [Pg.439]

There should be specific, saturable binding to the receptor, accompanied by pharmacological characteristics appropriate to the functional effects, demonstrable using a radioactive, eg, tritium or iodine-125, ligand to label the receptor. Radioligand binding assays (1,6) have become a significant means by which to identify and characterize receptors and enzymes (see Immunoassays Radioactive tracers). Isolation of the receptor or expression of the receptor in another cell, eg, an oocyte can be used to confirm the existence of a discrete entity. [Pg.517]

Carbon—carbon composites are used in high temperature service for aerospace and aircraft appHcations as weU as for corrosion-resistant industrial pipes and housings. AppHcations include rocket nozzles and cases, aircraft brakes, and sateUite stmctures. Carbonized phenoHc resin with graphite fiber functioned effectively as the ablative shield in orbital re-entry vehicles for many years (92). [Pg.307]

This catalyst system is temperature-sensitive and does not function effectively at temperatures below 10°C but at temperatures over 35°C the generation of free radicals can be too prolific, giving rise to incomplete cross-linking formation. Redox systems are preferred for fabrication at temperatures ranging from 20—30°C (Fig. 5). [Pg.318]

The effect of a second polymer blended with PPS which causes enhanced nucleation of PPS has been previously observed. It was found that low concentrations (1—2 wt %) of poly(phenylene sulfide ketone) and poly(ether ether ketone), when melt-blended with PPS, function effectively to increase the nucleation density of PPS (149). [Pg.451]

Recently, there has been increasing interest in the development of test methods to assess the possible adverse functional effects of exposing the fetus, both early and late in gestation (112,113). [Pg.237]

As these experiments with engineered mutants of trypsin prove, we still have far too little knowledge of the functional effects of single point mutations to be able to make accurate and comprehensive predictions of the properties of a point-mutant enzyme, even in the case of such well-characterized enzymes as the serine proteinases. Predictions of the properties of mutations using computer modeling are not infallible. Once produced, the mutant enzymes often exhibit properties that are entirely surprising, but they may be correspondingly informative. [Pg.215]

Adsorbers have minimum and maximum solvent concentration limits adsorbers will not function effectively outside those solvent concentration limits. [Pg.469]

Several chemical compounds can have an adverse effect on the heart and the vascular system. The effect may first appear as a transient change in the cardiac function. However, prolonged exposure increases the risk of permanent effects. Occasionally, functional effects such as cardiac arrhythmias may even lead to death. Furthermore, in many cases the effects of chemicals... [Pg.295]

The reader should be exposed to both micromechanics and macromechanics in order to function effectively in either material design or structurai design. The main thrust of this book is in iine with structurai design and analysis requirements. Thus, the point of our addressing micromechanics is to better understand how and why composite materials function. [Pg.185]

Testing should address the maximum operating temperature and pressure normally seen at the arrester location. This does not include certain pressure upsets (such as emergency shutdown) that produce unusually high system pressures. In many cases it may not be possible to design an arrester that will function effectively during upset conditions, and other protective measures should be considered (e.g., venting, suppression). [Pg.119]

It is important to keep in mind that any evaluation will reflect a snapshot in time, showing whether systems are in place and have been or are functioning. It is only by including appropriate characteristics of good management systems in the assessment that there can be assurance that these programs will continue to function effectively in the future. [Pg.88]

X 10 M), and an equivalent amount of OH (its usual concentration in plasma) would swamp the buffer system, causing a dangerous rise in the plasma pH. How, then, can this bicarbonate system function effectively The bicarbonate buffer system works well because the critical concentration of H2CO3 is maintained relatively constant through equilibrium with dissolved CO2 produced in the tissues and available as a gaseous CO2 reservoir in the lungs. ... [Pg.52]

Operational model, devised and published by James Black and Paul Leff (Proc. R. Soc. Lond. Biol. 220,141-162, 1983), this model uses experimental observation to describe the production of a physiological response by an agonist in general terms. It defines affinity and the ability of a drug to induce a response as a value of x, which is a term describing the system (receptor density and efficiency of the cell to convert an activated receptor stimulus into a response) and the agonist (efficacy). It has provided a major advance in the description of functional effects of drugs see Chapter 3.6 for further discussion. [Pg.281]

Health-related institutions again show the future trend in a microcosm. Suitable incineration facilities may determine the ability of such institutions to function effectively in an urban environment. When adequate processes for solid waste and air pollution control by incineration are developed, the use of combustible, one-way trip disposables for all incoming materials can be expected to accelerate. This will result in a decrease in the need for a direct fuel supply. [Pg.104]

The characteristics of an ideal liquid chromatography-mass spectrometry interface have been discussed, with emphasis having been placed upon the major incompatibilities of the two component techniques that need to be overcome to allow the combination to function effectively. [Pg.23]

APCI is not able to function effectively at very low flow rates. [Pg.184]
