background/purpose: although habitual consumption of xylitol reduces cariogenic streptococci levels, its effect on beneficial oral streptococci is less clear. the main aim of the study is to investigate the effect of short-term xylitol consumption on the oral beneficial streptococci level of saliva, streptococcus sanguinis and s. mitis . material and methods: twenty four volunteers with a media...


 Aim in this study to identify: 1) the effect of cable crossover training on increasing power and arm muscle strength; (2) shoulder press strength 3) a comparison between increase strength. There were 39 samples divided into 3 groups, each group consisting 13 samples. The type research used is quantitative with quasi- experimental procedures. design uses randomized control pretest- postte...

among various heuristics techniques, genetic algorithm (ga) is one of the most widely used techniques which has successfully been applied on a variety of complex combinatorial problems. the performance of ga largely depends on the proper selection of its parameters values; including crossover mechanism, probability of crossover, population size and mutation rate and selection percent. in this p...
