Dissolved concentrations of four forms of arsenic: arsenite, arsenate, monomethylarsenic, and dimethylarsenic, were measured in the Patuxent River Estuary near Benedict, Maryland, over two annual cycles. In each year, total arsenic concentrations peaked in the summer, in lateJuly and August, while minimum concentrations occurred in winter. Except in late winter, arsenate was a predominant form ...

Identifying the authorship either of an anonymous or a doubtful document constitutes a cornerstone for automatic forensic applications. Moreover, it is a challenging task for both humans and computers. Clustering documents according to the linguistic style of the authors who wrote them has been a task little studied by the research community. In order to address this problem, PAN Evaluation Fra...

Groups of the Guatemalan black howler monkey (Alouatta pigra) in a fragmented northern Guatemalan cloud forest in the Sierra Yalijux were analyzed for group composition and size using an ornithological census technique. Audio and visual records were combined to estimate each group’s home range size. The 361 observations in 2002 estimated 50 individuals in seven groups. Two home range classes we...

Derivatives in trigonometry have always been defined orthogonal contexts (i.e., where the y-axis is set perpendicular to x-axis). Within context of trigonometric, present work expands concept derivative (operating by principle 90 degrees phase shift when applicable sine and cosine functions) realm at a variable angle $\gamma$ x-axis non-orthogonal systems). This gives rise \emph{gamma derivativ...

Aiming at the internal leakage problem of spring type nuclear safety valve sealing surface, flow field and sound characteristics height 0.5mm between disc seat surface were studied, numerical simulation was carried out based on large eddy simulation(LES) mohring acoustic analogy method, compare effects wall pressure fluctuation(AWPF) turbulent fluctuation(TWPF) as excitation source external val...

Political scientists have shown that one can anticipate how a judge will decide a case more often than chance, or a reading of the facts, might allow by using various predictors such as party affiliation, gender, or the judge’s own decisions on earlier similar cases. The simplest explanation for such behavior is that judges first decide what they want the outcome of the case to be, then go back...
