Innovative Design Philosophy for Reinforced Concrete Structures
ISBN: 9783844318258 / Angielski / Miękka / 2011 / 156 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. This book provides a new solid background for the design of reinforced concrete structures. The practice of using f'c as a design parameter has been successful in the past and will continue to do so since there are numbers of strength reduction and load enhancement factors incorporated in the current design codes, which are entirely based on compressive strength of concrete. As a consequence the current design practice is not only leading to a more expensive design solution but also on the other hand suggests periodic revision of the building codes, as the upper limit of the concrete's...

Effects of Selected Xenobiotics on Amphibians
ISBN: 9783847325512 / Angielski / Miękka / 2011 / 72 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. Amphibians and reptiles are important elements of our natural biological heritage and known to be vulnerable to pesticides that are cholinesterase inhibitors. Several studies have reported that some pesticides reduce cholinesterase (ChE) activity in the frogs. Since the 1970s, significant decline in amphibian populations have been observed throughout the world including Pakistan, due to environmental pollution and some other factors. The amphibians and reptiles are considered to be good indicators of general environmental health. In Pakistan 29 species of amphibians have been recorded,...
