Both the “savanna hypothesis” and the “aquatic ape hypothesis” attempt to explain the bipedalism of humans—our tendency and ability to walk upright‚ on two feet. According to the savanna hypothesis‚ our ancestors left the forests in Africa for the plains. The males hunted and needed to survey the horizon and walk a great distance. So‚ they began walking on two feet to better accommodate this need. This hypothesis also explains our larger brain size since smarter individuals

STEPS IN SCIENTIFIC RESEARCH: ARCHITECTURAL RESEARCH: AN INTERDISCIPLINARY REALITY Hypothesis is a tentative explanation that accounts for a set of facts and can be tested by further investigation. Generation of Research Hypothesis Research usually starts with a problem. Questions‚ objectives and Hypotheses provide a specific restatement and clarification of the problem statement/research question. In qualitative research‚ the research question may assume two forms: The grand tour

possible market share‚ and to increase it further‚ it would have required additional price cut. So‚ the option with the firm was to expand its operation in the segment of specialty steel segment‚ which is typical mini mill product line. The alternative was to increase beam size capacity and directly challenge large integrated steel companies. Due to constraint of the rating of available rolling mill‚ it could make only small section beam. Manufacturing of medium and large section beams needed higher capacity

worked‚ over these four years? What was the outlook (as of the case date) for further progress in this matter? In 1975 Chaparral Steel commissioned minimill and started production. Minimills are different from traditional integrated steel plants. In minimill an Electric Arc Furnace (EAF) is used for steel making purpose and in downstream long product is made using rolling mill. The advantage of minimill is it requires less capital investment and a good solution when only long products needed to
