this study at first level focused on definitions and descriptions of  some landfills and landfills sites all around the world and  survey on how important they are for regional governments and responsible in duty  as a very important responsibility for locals and their health. at the second level we had a look on heavy metals concentration which are by many definitions as follows: lead, nickel,...

Results. After 10 minutes of ischemia, vitreal ERG band c-waves had recovered fully in 2 hours, and after 30 minutes of ischemia, recovered approximately 85% and 77% of their control amplitudes in 4 hours, respectively. At the early period of reperfusion after 10 minutes of ischemia we observed the supernormal c-wave (124% of its control amplitude, n = 10) with an elevated standing potential. T...

1.1. Azuma-Hoeffding Inequality. Concentration inequalities are inequalities that bound probabilities of deviations by a random variable from its mean or median. Our interest will be in concentration inequalities in which the deviation probabilities decay exponentially or superexponentially in the distance from the mean. One of the most basic such inequality is the Azuma-Hoeffding inequality fo...

is the fraction of HEADS in X n = (X1, . . . , Xn). Since θ = Eθ̂n , (1) says that the sample (or empirical) average of the Xi ’s concentrates sharply around the statistical average θ = EX1. Bounds like these are fundamental in statistical learning theory. In the next few lectures, we will learn the techniques needed to derive such bounds for settings much more complicated than coin tossing. Thi...

Brahn (3) observed very low liver catalase ac tivity in human beings who had died as the result of malignant growths. Later work showed that of all the individual liver enzymes studied in can cerous rats and mice the activity of catalase was by far the most affected. Greenstein and co workers (6, 7) have reported that with the pro gressive growth of the tumor there is a decrease in liver catala...

A core component of mindfulness is non-judgmental observation of internal and external stimuli. The present study investigated the effect of mindfulness on memory for emotional stimuli. Participants were exposed to a brief mindfulness intervention and subsequently performed a verbal learning test consisting of positive, neutral, and negative words. Control participants received no intervention ...
