Sustainability generally

Occluded applications Composition relatively invariant in use System size (area) predetermined Specific site prescribed for application Application technique highly reproducible Delivery is sustained Generally operate at unit drug activity, at least operate at steady activity Delivery is zero-order Serum levels related to product efficacy Bioequivalency based on pharmacokinetic (blood level) endpoint Unavoidable local tissue levels consequential only to system toxicity Individual dose interruptable Whole system removed when spent... 

By the end of April 2009, there was an Operationally Urgent Requirement (UOR) to support the 1200 personnel who deployed from Townsville as part of the force rotations to the Middle East Area of Operation (MEAO) and Timor which occurred during May-July 2009. This UOR lead to the transfer of MCBAS from L125-3B DCP Acquisition to DMO Sustainment in order to expedite the delivery of systems to the end-users in the field. Sustainment generally involves the provision of in-service support, maintenanee of equipment and purchasing of inventory. Sustainment can also be driven by Rapid Aequisition and Urgent Operatiorral Procrrrement procedures in support of operations. 

Hory X parameters are defined using a reference density, and their values depend on the value chosen. This density is denoted by poR in Eq. (33). In polymer-solvent systems, the solvent density is usually used for this, that is, poR = Pos. Less well appreciated is the fact that all Hory parameters have this dependence. For example, the xab in this expression depends on this choice. As a result, the value of xab would differ in different solvents, even for the same pair of polymers. In the absence of solvent, one must still specify the density used in the definition of the interaction parameter. For these reasons, por has been maintained here to sustain generality. 

Polyethers such as monensin, lasalocid, salinomycin, and narasin are sold in many countries in crystalline or highly purified forms for incorporation into feeds or sustained-release bolus devices (see Controlled-RELEASE technology). There are also mycelial or biomass products, especially in the United States. The mycelial products are generally prepared by separation of the mycelium and then drying by azeotropic evaporation, fluid-bed driers, continuous tray driers, flash driers, and other types of commercial driers (163). In countries allowing biomass products, crystalline polyethers may be added to increase the potency of the product. 

Calcium channel blockers cause more pronounced lowering of blood pressure in hypertensive patients than in normotensive individuals. Generally, all calcium channel blockers cause an immediate increase in PRA during acute treatment in patients having hypertension but PRA is normalized during chronic treatment despite the sustained decrease in blood pressure. These agents also do not generally produce sodium and water retention, unlike the conventional vasodilators. This is because they produce diuretic effects by direct actions on the kidney. 

Potassium and ammonium dichromates are generally made from sodium dichromate by a crystallization process involving equivalent amounts of potassium chloride or ammonium sulfate. In each case the solubiHty relationships are favorable so that the desired dichromate can be separated on cooling, whereas the sodium chloride or sulfate crystallizes out on boiling. For certain uses, ammonium dichromate, which is low in alkaH salts, is required. This special salt may be prepared by the addition of ammonia to an aqueous solution of chromic acid. Ammonium dichromate must be dried with care, because decomposition starts at 185°C and becomes violent and self-sustaining at slightly higher temperatures. 

It is generally seen that a human body can sustain a much higher current at a lightning or switching frequency (5 kHz or above) due to the extremely short duration of such surges (30 /is or less). 

The flash point represents the minimum temperature at whieh an ignitable mixture exists above a liquid surfaee. By definition, flash points are inapplieable to gases. Some solids, e.g. naphtlialene and eamphor, are easily volatilized on heating so that flammable mixtures develop above the solid surfaee and henee flash points ean be determined. (However, although these substanees ean be ignited, they generally need to be heated above their flash points in order for eombustion to be sustained this is the fire point .)... 

Theoretically, these intermolecular interactions could provide adhesion energy in the order of mJ/m. This should be sufficient to provide adhesion between the adhesive and the substrate. However, the energy of adhesion required in many applications is in the order of kJ/m. Therefore, the intermolecular forces across the interface are not enough to sustain a high stress under severe environmental conditions. It is generally accepted that chemisorption plays a significant role and thus, physisorption and chemisorption mechanisms of adhesion both account for bond strength.
