This paper develops and estimates a structural model of imperfect competition in international markets. The model incorporates a flexible non-linear demand framework with structural price equations, and a general Conjectural Variation approach is developed to characterize strategic interaction. The model is used to evaluate the effects of the signature by a small open economy, Lebanon, of a Pre...

The incorporation of recycling, which is the production of raw materials from old buildings and devices, is an increasing trend in industries worldwide. This increase in recycling is motivated by the conservation of energy and environmental resources, in particular, the decrease of carbon dioxide and green house gas emission by the intensive burning during various technological processes. The p...

We report the use of a simple yet highly effective magnetite-waste tea composite to remove lead(II) (Pb(2+)) ions from water. Magnetite-waste tea composites were dispersed in four different types of water-deionized (DI), artificial rainwater, artificial groundwater and artificial freshwater-that mimic actual environmental conditions. The water samples had varying initial concentrations (0.16-5....

Double-differential cross-sections for light-ion production (up to A = 4) induced by 96 MeV neutrons have been measured for Fe, Pb and U. The experiments have been performed at The Svedberg Laboratory in Uppsala, using two independent devices, MEDLEY and SCANDAL. The recorded data cover a wide angular range (20 degrees -160 degrees ) with low energy thresholds. The data have been normalised to ...

The leaching concentration of copper ions from the industrial sludge that has been extracted using sulfuric acid may still exceed 15 mg/L, which is the leaching standard of the toxicity characteristic leaching procedure (TCLP) for hazardous waste in Taiwan. Therefore, the acid-extracted industrial sludge is still an important source of hazardous waste. Usually, hazardous waste in Taiwan must be...

Nigeria is blessed with abundant iron ore deposits of nearly 3 billion tonnes and other basic minerals for steel production including coal and limestone. Yet the Nigerian steel sector has collapsed principally due to shortage of raw materials particularly iron ore for the integrated steel plants and billets for the rolling mills. The privatization of the steel sector that was done in 2004-2005 ...

Steel industry is one of the leading industries in the world. Today it is also one of the fundamental and strategic industries of the world. Per capita production and consumption amount of steel are used as a criterion for evaluation of country development. Furthermore, attention to technological innovations is assumed so much crucial to access the international markets of steel industrie...

Voltaire (1694-1778), the French philosopher said: “There are many ways to waste own time: Doing nothing, doing the wrong thing, doing the good thing at the wrong time” (own translation). The situation is quite different if the time is robbed by someone else or even by a professional mistake. There is a clear evidence that researchers on metallic iron (Fe0 termed as zero-valent iron) for water ...
