The pollution emitted into the air from mining-metallurgical complex negatively affects the environment. Plants have the ability to accumulate pollutants in their tissues. The concentration of heavy metals Ni, Zn, Mn and Cu, as well as sulphur, were determined in the edible parts of fruits. The fruits of apple, pear, peach and apricot trees were sampled in rural areas in the vicinity of the ind...

Ivascu, Faculty of Management in Production and Transportation, Politehnica University of Timisoara, Romania The paper presents the trends in the evolution of occupational diseases in Romania in comparison to the EU and the US, as incidence of occupational diseases, their interrelationship with the exposure to ...

It is well-known that some metals/alloys are sensitizing on skin contact, but it is not so well appreciated that sensitization is dependent on the reaction of the metal/alloy with sweat. The first step in skin sensitization by metals/alloys is a corrosion process and the formation of soluble metal ions. The nature of this process has implications with respect to occurrence of metal contact derm...

Oxygen top-blow converter is the main equipment in steel making, and its work reliability decides the security and economy of steel production. Therefore, how to design and test analysis of convertor has been an important subject of industry research. Geometric modelling and structure analysis of converter tilting device by using Pro/E program .The design Principle, basic design structure were ...

Introduction Powder metallurgy (p/M) is a rapidly expanding technology for manufacturing of structural parts. The PA4 process provides economical as well as technical benefits over conventional processing of wrought material. It is possible to fabricate high quality, complex parts to close tolerances without machining. The energy consumption is low and the material utilisation and productivity ...

This paper presents the key features of an engineering methodology dedicated to Organisation Networks. This methodology constitutes one of the elements of a full engineering framework developed through a PhD research thesis. The authors mainly focus hereafter on specifying the “design” and “preliminary engineering” activities of the engineering procedure. The methodology is illustrated on a cas...

This paper attempts to illustrate the benefits of using slag models based on the thermodynamics of steelmaking reactions and the multi-dimensional modeling of phase equilibria. The use of mass balance calculations and the application of these personal computer-based slag models to the refinement of standard operating procedures can simultaneously result in shorter process times, more predictabl...
