surface roughness is one of the most important parameters that plays very critical role in determining the quality of engineering components. a good surface quality resulting in improve of fatigue strength, corrosion and wear resistance of the workpiece. on the other hand, increasing cutting speed and decreasing time of machining are desirable for manufacturers in order to reduce costs and incr...

Beef cow-calf efficiency has been a topic of several review and symposium papers. A primary focus of many discussions on beef cowherd efficiency has centered on reproductive success and calf yield per cow, or more simplistically calf weight divided by cow weight. Reproduction and weaning weight are important but research has also demonstrated potential benefit from selecting for metabolic effic...

This paper considers a buyer who has to decide whether to select a single or two sources of supply for a homogeneous product. The production processes of the suppliers are subject to learning effects, which reduce the production costs and increase the production capacities of the suppliers. This, in turn, enables the suppliers to reduce the sales price, which results in lower acquisition costs ...

The wastes produced during the manufacture and use of paints have long been an environmental concern. Paint manufacturers have sought ways to reduce these wastes with significant success. Industrial paint users have also identified and implemented techniques and technologies to reduce their paint wastes. Frequently, these activities also result in reduced production and disposal costs. Despite ...

most companies in the chemical process industries (CPI) are striving to reduce manufacturing costs and increase production from existing assets. This article discusses how better approaches for plant instrumentation can help you to achieve and sustain these goals. Results at several companies prove that the following savings can be realized: • instrument maintenance costs reduced by greater tha...

Nacrtak The importance of forest wood chips as fuel for energy production will increase relative to sawmill by-products. The additional production is not a question of potential (harvesting residues, wood from thinning, coppice stands and short rotation forests) but more so a question of economic feasibility. The analyses of different chip production systems resulted in the identification of tw...

We study a standard duopoly model of simultaneous divisionalization and Cournot competition, assuming that firms have different marginal costs divisions are costless. obtain in equilibrium only the efficient firm active because price is equal to cost inefficient firm. In sequential case, however, this “entry-deterrence” strategy profitable for when its advantage important enough. So our setting...

Blade-type error, edge collapse cutaway, micro missing, four kinds of defect for RCF-type PCB mill production are deeply analyzed and their preventions measures are given detailed according to the author’s many year’s practice. These measures have been practiced and achieved good results. The research results can increase pass rate of such tools in the production and reduce production costs obv...

conclusions accidents resulting in death, total disability, and partial disability impose a huge cost burden on society, whereas the employer will bear a relatively low cost. this is because of society’s health, treatment, and welfare systems available for treatment and rehabilitation of injured employees and their families. background occupational accidents represent one of the major problems ...
