In the world of software systems, the process of evolving is an essential one. If this process represents no challenge on small systems, it becomes unbearable if the size of the system exceeds a certain limit. Therefore, the need arises for software tools that can carry out the necessary transformations automatically. This paper addresses the possibility to detect spots within an object-oriente...

Factory farming continues to grow around the world as a low-cost way of producing animal products for human consumption. However, many of the practices associated with intensive animal farming have been criticized by public health professionals and animal welfare advocates. The aim of this essay is to raise three independent moral concerns with factory farming, and to explain why the practices ...

The solid particle contamination is a challenge for the cement industries due to the highly dusty environment. The contaminants cause severe wear between moving surfaces and this in turn leads to rapid mechanical failure of the machine elements. The solid particle contaminants get into the lubricant among the metal surfaces due to the environmental conditions. The conditions get more severe in ...

Prevalence of asthma in children increase especially the industrial city. Cement factory Padang city is located near from community, cause air pollution, to children.

In a cohort of some 11,000 men born 1891-1920 and employed in the Quebec chrysotile production industry, including a small asbestos products factory, of 9780 men who survived into 1936, 8009 are known to have died before 1993, 38 probably from mesothelioma--33 in miners and millers and five in factory workers. Among the 5041 miners and millers at Thetford Mines, there had been 4125 deaths from ...

a mathematical method for calculation of the minimum cross-sectional area of a thickener is presented by obtaining minimum laboratory batch settling test data, a function, which is called settling function, is derived. this function is found to be in the form of a polynomial of third order. the settling function and mass flux relation are used for the design of thickener. the method predicts th...
