Polymer concrete, a composite material in which the binding material is some type of polymer, is being used more widely in the construction industry. Polymer concretes can also contain steel reinforcing rebars; therefore, the rate of adhesion between polymer concrete and reinforcing steel must be determined. Our study investigated the extent and behaviour of adhesion in the case of reinforcing ...

A. Morariu, I. Bostan, “Stefan cel Mare” University, Faculty of Economics, Suceava. When dealing with the issue of increased labour productivity in steel companies, as well as in any other economic sector, managers are faced with a diffi cult choice – investing in technologies and competencies or diminishing the number of jobs. The economic literature and statistical data available on the Roman...

This paper provides results from a series of projects investigating the application of PLS to provide process engineering solutions in the steel industry. These applications involve the prediction of final product quality in a LD converter, the prediction of NOx in a reheating furnace and an analysis of the effects that changing scrap types have on final product quality in an electric arc furna...

Using firm level data from the U.S. steel industry, we find that lobbying for import protection is habit forming. Controlling for firm performance and other factors, past lobbying increases the likelihood of current lobbying in our full sample. Expecting heterogeneity in lobbying behavior among firms, we let an EM algorithm sort our firms into groups with different propensities to lobby. A two-...

This paper reports results of in-house experimentation on heat treatment and mechanical testing of H13 tool steel. Heat treatment strategy practiced by the industry is described in detail. Effect of various types of heat treatment on fracture toughness, hardness and other mechanical properties is also analyzed. It was found that toughness (expressed in terms of plane-strain fracture toughness K...

We investigated the suitability and applicability of Pseudevernia furfuracea (L.) Zopf for environmental genotoxicity assessment. P. furfuracea lichen specimens were collected from 10 different Pinus species, in every 5 km, starting from around an iron-steel factory located in the central area of Karabük Province up to Yenice Forest. The impact of the pollution sources such as iron-steel f...

nowadays, by increasing the emphasis on the environmental protection by organizational stakeholders, including government, customers, employees, competitors and communities, environmental management is becoming more important for corporations. integrating environmental management techniques along the supply chain is an appropriate method for enhancing the environmental performance of an industr...

choice for pharmaceutical industry process systems. Its high mechanical strength and low coefficient of thermal expansion allow components to be sterilised or sanitised using various mediums and at high temperatures. Concerns about stainless steel systems – such as rouging in high purity water, metallic ion contamination and inner surface finishes – which require post-installation maintenance a...
