 Unlike other domesticated creatures, the house cat contributes little to human survival. Researchers have therefore wondered how and why cats came to live among people.  Experts traditionally thought that the Egyptians were the first to domesticate the cat, some 3,600 years ago.  But recent genetic and archaeological discoveries indicate that cat domestication began in the Fertile Crescent,...

In this study, the impacts of different proportions tension reinforcement and waste lathe scraps on failure bending behavior reinforced concrete beams (RCBs) are clearly detected considering empirical tests. Firstly, material strength consistency test then ½ scaled beam have been carried out. For purpose, a total 12 specimens were produced in laboratory tested to examine mechanism under flexure...

In this study, we reported a simple and easy process for zeolite synthesis using waste glass aluminum scraps. The silica source was obtained from of the end-of-life fluorescent tubes scraps collected workshop in region Sfax, Tunisia. zeolitic materials were prepared by hydrothermal treatment at 60 °C 6 days 10 g powder mixed with 100 mL sodium aluminate solution order to optimize nature recover...

Industrial and experimental induction furnaces are used for melting various types of iron ingots, returned scraps and DRI sponge pellets to produce high purity cast - iron and steel heats. The lowest consumption of electrical energy determined for continuous feeding operation is 0.3 KWH/Kg for the production of cast - iron in a 1.5 - ton industrial furnace and 0.45 KWH/Kg for the production of ...
