General performance issues

There are several general performance issues that should be investigated when troubleshooting an RO system. These include the following issues

Safety-related training is used to close gaps in knowledge about hazards and associated risk, as well as the necessary controls that are to be consistently used. A safety-related problem may be a precursor to general performance issues impacting productivity or other organizational effectiveness or drivers. For example, an employee may not have an... 

Incentive measures are generally used to draw attention to PSM and ESH performance issues that are, to some extent, controlled by worker behavior or management attention. These measures are frequently used for distributing incentive awards or at-risk pay when particular targets are met, for example 1 million hours without an injury or a target number of changes processed correctly. Whether your company uses incentive measures and awards is a matter of corporate practice. 

Detecting explosives in complex environments requires very sensitive and specific analyzers. Though MS offers excellent detection limits and resolutions (e.g., sensitivity and specificity), general-purpose laboratory instrumentation is not ideally suited for detecting trace levels of explosives in the presence of large abundances of potential interferent compounds. Furthermore MS has traditionally required a skilled operator not only to acquire data but to interpret it. MS developments have tended to focus on the performance issues and less so on the operational issues. 

Poiymers which are 100% acrylic are known for their outstanding exterior durability properties, as well as excellent alkali resistance and overall high performance. Styrene is generally lower-cost than many other monomers, so styrene-acrylics are lower in cost than all acrylics but have poorer exterior durability because styrene is a UV absorber and degrades. Styrene-acrylics, do, however, generally have very good water-resistance properties due to their hydrophobicity. Styrene acrylics are popular in some areas of Europe, Asia, and Latin America. Vinyl acetate is also somewhat lower in cost, so these polymers are popular for interior paints, particularly in the United States, where exterior durability and alkali resistance are not performance issues. 

High-concentration NjO has been decomposed catalytically with four metal oxide systems which contain s, p, ti-block elements. In all cases, the decomposition reaction can be treated as first order with respect to partial pressure of N O, considering that decomposition product O2 exhibits no or little inhibition effect on the reaction. Optimal preparation conditions for the catalysts have been explored. In particular, chemical interaction between surface metals and carriers has been investigated. The catalysts have been characterized by various analytical techniques and general material issues have also been addressed. Among the four systems studied, Ru/AljOj and Mg-Co mixed oxides give best catalytic performance. For example, approximately 6 moles of NjO per kg of the hydroxide/hydrotalcite can be decomposed at 350°C within an hour. 

It is generally desirable to select the most thermodynamically stable crystal form for formulation development. This form will usually have the least liability for phase tranistions and will often be the most chemically stable form. Sometimes, however, a metastable form is selected either for performance issues or because the stable form is not obtainable directly (or for historical regulatory reasons). Under these conditions, it is imperative that the solid state system be thoroughly... 

Sweat management has been a key requirement for sportswear for some time. It is generally accepted that excessive sweat deposited onto the skin leads to discomfort and potentially other performance issues. Textile technologies to manage sweat have been in place for a number of years and include wicking yams and fabrics that carry sweat away from the skin and cooling fabrics that help reduce excessive heat on the skin. 

Despite the redistribution issues that these radiolabel studies served to identify as a significant performance limitation, V and closely related V-formylsalicylamides generally performed very well vs. P. viticola in vineyard trials (see Table III). However, there appeared to be inconsistent robustness of disease control assessed on foliage that emerged subsequent to fungicide treatment. The data presented in Figures 2-4 would imply that the V-formylsalicylamide chemistry would be unlikely to deliver adequate new-growth disease protection under vineyard conditions, at least if vascular transport were the only vehicle for re-distribution. 

A number of the issues discussed above seem potentially relevant to the U.S. nuclear power industry. In particular, human performance is critical to safety in all three case study industries as well as in the U.S. nuclear power industry. This is partly because the effectiveness of many hardware-based safety features can be compromised or even negated by inappropriate human actions, but also in part because other (e.g., equipment-related) causes of safety problems have often been addressed more successfully than human performance. Therefore, in the remainder of this section, we discuss the experience of the U.S. nuclear power industry with respect to downsizing, use of contractors, and overall human capital (e.g., experience levels and qualifications), in addition to general human performance issues that may be associated with deregulation. Labor relations are discussed in detail in the next subsection. 

Today, few new applications of open tubular SFC are developed and no hardware is manufactured specifically for this use. The general lack of interest in open tubular SFC stems from the inherent low polarity of carbon dioxide, and the lack of other more polar alternatives. There are also performance issues.

One approach to compensate for buoyancy and general baseline issues encountered with very small mass loss is to perform a second experiment with a closely matching inert sample and subsequently subtracting this blank experiment. A series of such experiments can be stored for future use. An excellent example of this technique was the determination of the coating thickness on fused-silica fibers (Gallagher 1992). Fibers were initially heated in an oxidizing atmosphere to burn off the very thin polymer coating. They were...
