The order of discovery can have a profound effect upon the way in which we think about the function of a gene. In E. coli, recA is nearly essential for cell survival in the presence of DNA damage. However, recA was originally identified, as a gene required to obtain recombinant DNA molecules in conjugating bacteria. As a result, it has been frequently assumed that recA promotes the survival of ...
abstract type-ii fuzzy logic has shown its superiority over traditional fuzzy logic when dealing with uncertainty. type-ii fuzzy logic controllers are however newer and more promising approaches that have been recently applied to various fields due to their significant contribution especially when the noise (as an important instance of uncertainty) emerges. during the design of type- i fuz...
This study was investigated the effects of static magnetic field (SMF) on the serum cortisol hormone, biochemical and hematological parameter in 12 mature female rabbits, six of them were exposed to electromagnetic field of 104μT for 30 minutes twice daily for 15 days. The other six female rabbits served as control .Blood samples were collected from treated and control rabbits. Results revealed...
Burning rate accelerating catalysts are reckoned to be of important additives in the synthesis process of composite solid propellants on which much effort is made these days to suggest a novel procedure for their synthesis. Among many tasted chemicals, liquid ferrocene derivatives have been used much more vastly due to their better performance and suitable processability. But, these compounds s...
College students, especially women, demonstrated negativity toward math and science relative to arts and language on implicit measures. Group membership (being female), group identity (self female), and gender stereotypes (math male) were related to attitudes and identification with mathematics. Stronger implicit math male stereotypes corresponded with more negative implicit and explicit math a...
