J. Kliber, VŠB – Technical University of Ostrava, Faculty of Metallurgy and Materials Engineering, Czech Republic Metal forming can be regarded as a process during which materials are treated by “force” and “heating” under a certain external load and boundary condition (loading mode, rate of loading, constraint condition, geometry, contact friction condition, temperature field). As well as in f...

Metal matrix composites (MMCs) are now gaining their usage in aerospace, automotive and biomedical industries because of their inherent properties like high strength to weight ratio, low wear rate etc. To machine these types of materials conventional machining methods are unsuitable because of high tool wear and tooling cost. Electro discharge Machining (EDM) is one of the important nontraditio...

Since 1995 as a start of commercial use of Internet network in Finland we have witnessed strong development in this area. This development trend has promoted e-Business to an important subject of decision-making and business planning. One of the factors behind development has been the exploitation and management of information and knowledge. Next step, which is already there observable in some ...

Rise and development of the e-Business has led to transformation of many traditional markets and born of new ones. Companies have been forced to change themselves to be more customer oriented and turn their mass production strategy to mass customization strategy. In this research we outline the development paths of forty case companies in Finnish metal and electronics industries. Objective was ...

This paper attempts to replicate a safety climate model originally tested in Australia to assess its applicability in a different context: namely, across production workers in 22 medium-sized metal processing organizations in Austria. The model postulates that safety knowledge and safety motivation mediate the relation between safety climate on the one hand and safety compliance and participati...

The polyamine (PA) was prepared by condensation of 1, 4-bischloromethyl benzene and 1, 4benzene diamine. The PA was then treated with cyanuric chloride at 0oC followed by reaction with sulfanilic acid in THF in concentrated NaOH (pH 9-10) at room temperature for 8 hrs. The resultant polymer designated as polyamine-s-triazine-sulfanilic acid (PATS) was characterized by elemental analysis, IR spe...

Over 2000 electrocution deaths were identified among U.S. construction workers from 1980 to 1991, with the highest mean annual crude mortality rate (2.5 per 100,000 people), and second highest mean age-adjusted rate (2.7 per 100,000 people) of all industries. Although the crude fatality rates showed a downward trend, construction workers are still about four times more likely to be electrocuted...

Purpose: Increasing salt of water is a world-wide problem, heavy metals belonging to the most important matrials. The progress of industries has led to increased emission of pollutants and salt of water into ecosystems. Tajan is one of navigable river in the Northh of Iran. Along the Tajan agricultural industries units such as piping, steel, paint making, paper mill, fish cultivation, abbottior...
