Recent excavations made by University of Lecce in Piazzetta Epulione and Piazza Castromediano (Lecce) have produced structures and artifacts related to metal-working. Most of the evidence dates back to the Roman period; traces of metallurgical activity can also be traced to the periods preceding and following the Roman period. Iron slags and semi-finished objects have been found in Piazzetta Ep...

We propose a systematic method for creating constellations of unitary space–time signals for multiple-antenna communication links. Unitary space–time signals, which are orthonormal in time across the antennas, have been shown to be well-tailored to a Rayleigh fading channel where neither the transmitter nor the receiver knows the fading coefficients. The signals can achieve low probability of e...

Abstract. The metallurgical and steel processing industries are considered strategically important as they form the basis of a country's industrial competitiveness sustainable economy.Recently, value minerals demand for metals increasing. Thus, it is essential to build factory in Mongolia based on needs national consumption neighboring countries market demand. Therefore, crucial select suitable...

Methodology. Methods used are: abstraction critical analysis forming theme purpose work; content analytical review literature; ascent from abstract concrete form an algorithm developing strategy reconstructi...

The use of steel-making slag as catalysts for microwave-assisted dry reforming of CH4 was studied. Carbon materials (an activated carbon and a metallurgical coke), mixtures of carbon materials + Fe-rich slag and mixtures of carbon materials + Ni/Al2O3 were tested as catalysts. Mixtures of slag with carbons gave rise to higher and steadier conversions than those achieved over carbon materials. T...

B. Gajdzik, The Silesian University of Technology, Faculty of Materials Science and Metallurgy, Katowice, Poland Before metallurgical enterprises started implementation of marketing activities they had to go through restructuring processes which included all areas of their market activities. Privatised metallurgical enterprises after economic transformation gradually implemented marketing to th...

In modern economic literature, several strategies for the development of enterprises are considered at theoretical level. However, as an independent form strategy, foreign activity strategy is not considered, or enough attention paid to it. The purpose article identify Russian in oil and gas, metallurgical industries, food industry, based on their annual reports ratings analytical agencies. obj...

The purpose of this study was to establish the validity and reliability of a hydrostatic weighing method using total lung capacity (measuring vital capacity with a respirometer at the time of weighing) the prone position, and a small oblong tank. The validity of the method was established by comparing the TLC prone (tank) method against three hydrostatic weighing methods administered in a pool....
