Critical element

In the sheeting market, the low density polyethylenes are less important than the high density resins. The high density resins have excellent chemical resistance, stress-crack resistance, durabiUty, and low temperature properties which make them ideal for pond liners, waste treatment faciUties, and landfills. In thicker section, HMW-HDPE sheet makes good containers, trays, tmck-bed liners, disposable items, and concrete molds. The good durabiUty, abrasion resistance, and light weight are critical elements for its selection. 

The principal objective of technical service in the chemical industry is to provide timely and professional information and support to downstream customers regarding chemical products and thek uses. It is neither cost-effective nor necessary for a consumer of chemical products to develop a staff of speciahsts having detailed expertise in all aspects of chemical raw materials and thek uses, particularly in a time of increa singly complex and rapidly technologically driven economies. Rather, this variety of expertise is provided in the chemical marketplace by technical service professionals whose knowledge and skills are made available by chemical products suppHers. As such, successful chemical companies provide technical service as a critical element of thek offerings to the marketplace making use of this aspect of the value chain to enhance thek competitiveness. 

In the presented work an algorithm for the primary radiation filter optimization has been developed and realized in the Mathcad envelope which provides a minimal detection limit of a critical element both at the given X-ray tube power and at the given maximal acceptable count rate. 

It should be started as early as possible once the concept designs have been generated from initial requirements, generating information on the critical elements of the design. 

The design of this alloy was unique in that it utilized phase stability and other predictive techniques to balance the levels of critical elements (Cr, Mo, Co, Al, Wand Ta), thereby maintaining the hot corrosion resistance of IN-738 at higher strength levels without compromising phase stability. Most... 

Quality records A critical element in improving performance is establishing measurements of performance which can subsequently be analyzed to identify opportunities for improvement. ... 

The plant engineer and his maintenance manager will establish whoever carries out the work, basic strategy, programming and procedures. Inspection checklists and record sheets are necessary for systematic location of critical elements/potential defects and setting out frequencies of inspection. Computers and work processors are an obvious aid to effective maintenance management. Inspection-based preventive methods are demonstrably cost effective. 

Heat sink A device for the absorption or transfer of heat away from a critical element or part. Bulk graphite is often used as a heat sink. 

The different classes of Ru-based catalysts, including crystalline Chevrel-phase chalcogenides, nanostructured Ru, and Ru-Se clusters, and also Ru-N chelate compounds (RuNj), have been reviewed recently by Lee and Popov [29] in terms of the activity and selectivity toward the four-electron oxygen reduction to water. The conclusion was drawn that selenium is a critical element controlling the catalytic properties of Ru clusters as it directly modifies the electronic structure of the catalytic reaction center and increases the resistance to electrochemical oxidation of interfacial Ru atoms in acidic environments. 

The most critical element in melt-growth of single crystals is the container, or crucible. The first requirement for selection of a suitable crucible is that the crucible does not react with the melt. The second is... 

Envlroiunental testing Is a critical element In this process since It enables the qualitative and quantitative determination of toxic chemicals In the environment and the definition of environmental pathways which may lead to human exposure This paper briefly reviews the overall process of health risk assessments and the particular role which environmental testing plays Recent efforts to assess environmental health risks In relation to Love Canal Illustrate both the usefulness and the limitations of environmental testing In risk assessment ... 

The reproducibility of a determination is a critical element of a standard method, so they are carefully written to ensure that they can be followed accurately by any qualified laboratory. The designated test biological RMs must not only be reproducible in their reactions to the performance tests, but they must also respond in a predicable manner. In order to guarantee that the same strain of microorganisms could always be available, many of these biological RMs have been deposited with the ATCC and other culture collections around the world. 

Cappuccino lovers would argue that the foam cap on the drink is the critical element to a great cappuccino. Steam frothing of milk to prepare a cappuccino coffee involves injecting air and steam into milk to create the foam and to heat the milk to near boiling.

The likelihood of a successful resuscitation outcome is enhanced if each of four critical elements in the chain of survival is implemented promptly (1) early recognition of the emergency and activation of emergency medical services (2) early bystander basic life support and CPR (3) early delivery of a shock with a defibrillator and (4) early ACLS followed by resuscitation care delivered by healthcare professionals. 

Because, for each of the three cases, 20 precursors are analysed, a comparison between the results of all three cases is possible. From the results of the analysis it appears that in all three cases, most precursors were enabled by the ineffective judgement element on the tactical control level. In companies A and B, the judgement element on the operational control level is the ineffective control element enabling the second most frequent precursors, while for company C the judgement element contains the most precursors on the strategic control level and appears to be a critical element at each control level for all three companies. Moreover, relatively more ineffective control elements are present on the higher (tactical and strategic) control levels in company C (18), than in company A (12) and B (11). 

The user interface is a critical element for planners and planning stakeholders acceptance of a planning system. The developed main user interface is structured... 

Drug-related problems can be defined as Any undesirable event experienced by the patient that involves or is suspected to involve drug therapy and that actually or potentially interferes with a desired patient outcome (Strand et al. 1990). This is a vital component of Pharmaceutical Care and Clinical Pharmacy and will be described more in detail in another chapter. It should however be noted that there are several definitions and classification systems for DRPs. A literature review (van Mil et al. 2004) identified fourteen classifications and their critical elements. In the presented definition a potential problem is a DRP but this is not the case in all definitions and classifications. This is also the case for unavoidable adverse drug reactions (e.g. with cytotoxic agents). 

Several factors contribute to hurricane formation, including El Nino cycles, upper stratospheric circulation patterns and the rain in the Sahara area of Africa. The 2004 hurricane season was mostly due to the alignment of these critical elements. The general agreement on climate change and hurricanes is that hurricanes may not become more common but that they may increase in intensity.
