The development of the internal orientation in formation in the fiber of a specific directional system, arranged relative to the fiber axis, of structural elements takes place as a result of fiber stretching in the production process. The orientation system of structural elements being formed is characterized by a rotational symmetry of the spatial location of structural elements in relation to the fiber axis. Depending on the type of structural elements being taken into account, we can speak of crystalline, amorphous, or overall orientation. The first case has to do with the orientation of crystallites, the second—with the orientation of segments of molecules occurring in the noncrystalline material, and the third—with all kinds of structural constitutive elements.

Under certain conditions, such as high water temperatures, insufficient water supplies and problems of blowdown disposal, systems that depend on convection and use air as the transport medium may be preferable. The two types of dry cooling towers are the direct and indirect systems. Figures 4.21 and 4.22 show these systems in operation for nuclear station cooling. Indirect units use a surface or jet condenser at the turbine to condense exhaust steam. Water from the condenser is pumped to the dry tower for cooling and recirculation back to the condenser. In the direct system, steam is condensed in cooling coils without interfacing with a condenser. 

The major difference between the two systems is the large volume of exhaust steam that must be handled in the direct system, as compared to the smaller volume of circulating water in the indirect system. Cooling... 

Dry towers for power plants are of three types. The direct system wherein steam is condensed directly in the dry tower the indirect type wherein water is cooled in a dry tower and then used to condense steam in a direct contact condenser and the indirect type wherein water... 

The controls of both the "open" and the "closed" direct systems are very simple, because they consist of only a differential thermostat and a pump. The differential thermostat starts and stops a constant-speed pump whenever the detected temperature difference is favorable. In more sophisticated systems, it adjusts the speed of variable-speed pumps (or selects a small or a larger constant-speed pump for operation). What AT is "favorable" is a function of not only the "availability" of free cooling or free heating, but also of the cost of pump operation, which increases the AT thermostat set point. 

The discovery of enzyme systems by which D-glucose could be isomerized directly to D-fructose was a key factor in the development of commercial-scale isomerization-processes. These direct systems were developed from fundamental studies of carbohydrate metabolism, in which was identified for the first time an enzyme that catalyzes the isomerization of an unsubstituted sugar, namely, the isomerization of D-erythrose to D-g/ycero-tetrulose.31... 

The readout of the cathode plane is somewhat more complicated, since the induced signals extend over several elements. The determination of the position of the avalanche is done by the so-called center of cluster method. The thresholds of the discriminators are chosen such that the induced signal of several cathode wires switches them (see Fig. 13). Two priority encoder systems are connected to the cathode plane in opposite directions. Priority encoders produce the address of the highest numbered input element which receives a signal. Since the systems are connected in opposite directions, system A will deliver the address of the higher numbered cathode wire whose signal is above the threshold value. System B gives the address of the lower wire. 

At present, the known catenanes can be divided into two categories - those prepared by metal template synthesis and those synthesised in the absence of a metalion influence. A considerable number of catenanes of the first type have been prepared by Sauvage et al. as well as by a number of other workers. However, discussion on these important metal-ion-directed systems is deferred to the next chapter in which particular supramolecular assemblies produced by metal-ion-controlled procedures are discussed. 

System Type. The three basic types of SCF cleaning systems are the direct system, in which supercritical carbon dioxide (SCCO2) is the only cleaning solvent, the single-cycle system, in which the SCCO2 is mixed with a cosolvent and the dual-cycle system in which the parts are exposed separately to cosolvent and supercritical carbon dioxide. 

Information on archaeal translation is essentially based on poly(U)- and poly(UG)-programmed cell-free systems and on peptidyltransferase assay systems. Poly(U)-directed systems have been used to monitor the reconstruction of archaeal ribosomal subunits and the susceptibility of archaea to protein synthesis inhibitors. 

A Poly(U)-programmed cell-free system from H. cutirubrum requiring saturating salt concentrations was developed by Bayley and Griffiths [117] ten years before extreme halophiles were assigned to the newly discovered archaea. Poly(U)- and poly(UG)-directed systems using purified ribosomes and post-ribosomal supernatant fractions have been subsequently developed from most known archaea. 

Scheme 2 Some possibilities for the pharmaceutical technologies and approaches to be used in personalized medicine, ranging from simple liquid oral dose forms where the dose can be varied by volume, through responsive systems, micro-electromechanical systems (MEMS), GPS-directed systems (see text) transdermal systems, thin film technologies with passive or active release mechanisms, combination tablet or capsule dose forms, and what we term dosed solid platforms, for example, aqueous dispersible polymer, solid gel or matrix material into which precise doses of drag can be absorbed.

On account of the infinite length of the chemical stripes in the y-direction, system properties are translationally invariant in that direc tion. Hence, fl is a homogeneous function of degree 1 only in Sy and therefore... 

No studies were located concerning death in humans after dermal exposure to selenium or selenium compounds. In a range-finding study using mice dermally exposed to selenium sulfide for a maximum of 17 applications, 8 out of 20 animals died at 714 mg selenium sulfide/kg (NTP 1980a). However, the effects noted in this study were equivocal since there was no indication that the application sites were covered to prevent ingestion. Further, severe skin damage developed, and this may have led to direct systemic absorption of the compound. 

In [1] McClure describes IMG, a compiler writing system. Although TMG Is a syntax directed system, Its recognition schema differs in some respects from previously known schemas. The formalization of this recognition schema and the study of Its properties form the goal of this work. 

Systemic absorption of epinephrine-related drugs and 13 adrenergic antagonists can induce all the side effects found with direct systemic administration. The systemic use of CAIs may give some patients significant problems with malaise, fatigue, depression, paresthesias, and nephrolithiasis the topical CAIs may minimize these relatively common side effects. 

Cyclization studies were carried out in sealed tubes in toluene solutions at 165 °C and provided excellent yields of the corresponding bicyclic cycloadducts in 5-9 h. Reactions of tertiary alkyl ethers showed moderate to complete trans selectivity. This selectivity was observed even for inherently cw-directing systems and may be attributed to the gem-dimethyl group in the ether tether comparison of the reacting conformations leading to cis- and rrans-fused decalins reveals, in the cis case, an unfavorable non-bonding interaction between the axial methyl group and H-C(3) of the diene (Scheme 10-15).
