Arsenic (As) contamination in the groundwater of Bangladesh is one of the major public health concerns. It has become a challenge to remove As from groundwater and a great deal of efforts employed in this regards with limited success. Cerium oxide is one of the important medias of arsenic removal techniques. Nine units of cerium-based arsenic technology were tested with seven different well wat...

We generalize an integral representation for the ruin probability in a Crámer-Lundberg risk model with shifted (or also called US-)Pareto claim sizes, obtained by Ramsay [14], to classical Pareto(a) claim size distributions with arbitrary real values a > 1 and derive its asymptotic expansion. Furthermore an integral representation for the tail of compound sums of Pareto-distributed claims is ob...

LCLF: Why another book about “nature versus nurture”? Doesn’t everyone now agree it’s both? JT: The nature/nurture debate is a funny thing. On the one hand, you’re right; it’s very common to hear someone say, “Of course it’s not nature versus nurture; it’s both nature and nurture.” On the other hand, we hear reports all the time about some new study that claims nature trumps nurture when it com...

The pleading burden that governs securities-fraud litigation is significantly higher than those standards that govern traditional civil cases. The heightened pleading burden applicable to securities cases has transformed the motion to dismiss into something like summary judgment. In fact, to contend with this heightened pleading burden, plaintiffs typically must spend more time in the prefiling...

(1) Many modern historians of science are so preoccupied with local scientiac practices that they fail to recognize important non-local elements. (2) Many modern philosophers of science make a sharp distinction between explanation and evidence,...
