Cost versus effectiveness

It should be pointed out that although wound dressings may not be able to promote the healing process significantly, the use of inappropriate dressings can often cause delayed wound healing. This may result in various complications of poor wound management. 

Increased demand for nursing time and increased dressing costs. 

In order to provide the best solutions for wound-care practitioners, new types of advanced wound dressings and wound-management materials are being developed to provide the means of ensuring the best possible patient outcome. The aims of the new developments can be summarized into the following three areas. 

These three E s symbolize the goal-oriented approach in the current and future development of wound-management materials and products.

In order to understand the effect of each term on the overall objective function of the system, different values of 0i and 02 are evaluated to construct the efficient frontier of expected cost versus risk measured by standard deviation. This will be demonstrated in the illustrative case studies. 

On your chart showing the cost versus time of oil, coal and gas, you had the coal rising somewhat in parallel to the price of oil, and the implication was that the coal was really responding to the rising cost of oil. It seems to me that it is probably more complicated than that, and I wonder if you have made any analysis of the effect of the various laws, the Mine Safety Act, etc., on the price of the coal. 

Spent Catalyst. Opportunities may exist to reduce the volume of waste catalyst by reusing the catalyst through several hydrogeneration batches however, experts disagree on the final benefit of this. The measurement of this can be made by measuring hydrogeneration efficiency versus catalyst disposal costs. Other catalysts have been explored however, their costs and effectiveness are less desirable. These catalysts have environmental problems of their own because they are heavy metal-based. 

Similar findings resulted from a study sponsored by the National Institute on Drug Abuse of 10,000 clients in nearly 100 treatment programs and in a metaanalysis of 78 separate drug treatment outcome studies. In addition, a summary of 51 published and 17 unpublished reports regarding the costs versus benefits of substance abuse treatment firmly validated the cost-effectiveness of treatment. ... 

The ordering above is not arbitrary but reflects the preference described in ANSI/ANS-8.1, paragraph 4.2.3. The three approaches are listed in order of their effectiveness but, unfortunately, in opposite order of their usual cost of implementation. Therefore, the exact controls chosen for a particular process follow the familiar trade-off of cost versus safety benefit. 

Section 3(c)(5) requires pesticides entry to the market have their chemical composition support claims for use, meet labeling requirements, and perform the claimed function without unreasonable adverse effects on the environment. This requirement that there not be unreasonable risks of harm to humans or ecosystems foretells analysis for costs versus benefits and is assumed to include the cumulative effects of multimedia exposures to the pesticide. 

The form factor affects both fuel and capital costs since there Is a limitation on maximum channel power output thus the number of channels In the core varies with the form factor. In assessing the optimum discharge irradiation, this effect must be included. To do this, it is assumed that the electrical power output is fixed and the core size is adjusted in proportion to the form factor variation. The difficulty with this approach Is that, for the practical situation to retain core symmetry, channels must, in general, be added In groups of 8 so that the plot of generating cost versus discharge irradiation has discontinuities. 

Cost Versus Price. Finally, cost versus price is a special difficulty in the software field. The complexity of the front-end software is a major factor in the cost, in that more complex software needs to be more highly priced. It takes more work and expertise to develop and this makes it more useful. But, ironically, this complexity may not be apparent to the user especially in the best designed and most serviceable software By analogy, consider that when a system of the human body works well, you tend not to notice it. STN Express software is actually quite complicated programs that appear simple in their execution may have cost the developer months of programming, many thousands of lines of code, and hours of design and prototyping. And this must have some effect on the price. 

In an economic comparison of these three common abatement systems, a 1991 EPA study (58) indicates extended absorption to be the most cost-effective method for NO removal, with selective reduction only matching its performance for small-capacity plants of about 200—250 t/d. Nonselective abatement systems were indicated to be the least cost-effective method of abatement. The results of any comparison depend on the cost of capital versus variable operating costs. A low capital cost for SCR is offset by the ammonia required to remove the NO. Higher tail gas NO... 

Number of effects versus steam, water, and pump power cost. 

Distribution of heating surface between effects versus evaporator cost. 

In weighing the pros and cons of inside staff versus outside contractors, the most useful determinant is long-range cost-effectiveness. It s easy to underestimate the true cost of using employee resources, since these expenses are "buried" within ongoing business. 

The commercial units have a very low thermal capacity and very high response speeds. Some are available with several independent channels and a common cold junction. Each channel is scanned in turn by the instrument, and the readings either displayed or stored for future recovery. Accuracies of better than 0.2 per cent are possible. Thermocouples are available to cover a very wide range of temperatures, their cost is low and they have a small mass, so minimizing the intrusive effect on the surface at the point where the temperature is being measured. The output characteristics (output voltage versus temperature) are reasonably linear but the measurement accuracy is not particularly high.
