BACKGROUND Polar bears (Ursus maritimus) of the Beaufort Sea enter hyperphagia in spring and gain fat reserves to survive periods of low prey availability. We collected information on seals killed by polar bears (n=650) and hunting attempts on ringed seal (Pusa hispida) lairs (n=1396) observed from a helicopter during polar bear mark-recapture studies in the eastern Beaufort Sea in spring in 19...

While high-throughput planar patch-clamp instruments are now established to perform whole-cell recordings for drug screening, the conventional micropipette-based approach remains the gold standard for performing cell-attached single-channel recordings. Generally, planar platforms are not well-suited for such studies due to excess noise resulting from low seal resistances and the use of substrat...

in analyzing and explaining seal of prophethood as a doctrine, almost all scholars who have dealt with this issue considerhuman intellectual maturityas the main criterion and the secret of the emergent finality.the present article explains and analyzes the proposed approaches and perceptions regarding intellectual maturity and thus aims toreview this idea critically.as a result,the study shows ...

Measurement of fault rock and seal rock flow properties presents considerable problems, even in the controlled conditions of the laboratory. Estimating of the sealing capacity and rate of leakage across faults or shale layers is an even greater challenge. The purpose of this contribution is to examine, with examples, how a combination of existing and novel petrophysical methods could reduce unc...

In this paper quantum seals will be introduced. A quantum seal is a way of encoding a classical message into quantum states, so that everybody can read the message error-free, but at the same time the sender and all intended readers who have some prior knowledge of the quantum seal, can check if the seal has been broken and the message read. The verification is done without reading nor disturbi...

objective: the aim of this study was to evaluate the dimensional stability of casts made from an alginate impression material poured immediately and stored after specific periods. materials and methods: the common alginate used in iran (super; iralgin, golchai co., tehran, iran) was tested. a master model was mounted on a special device and used to obtain the impressions. these impressions were...

People often draw trait inferences from facial appearance of other people. We investigated the minimal conditions under which people make such inferences. In five studies, each focusing on a specific trait judgment, we manipulated the time exposure to unfamiliar faces. Judgments made after 100 ms exposure highly correlated with judgments made in the absence of time constraints, suggesting that ...

F details endure about the life and family circumstances of Flemish painter Cornelius Norbertus Gijsbrechts. We know that he was born in Antwerp, Belgium, and his talent earned him a position of court painter with two Danish kings, Frederick III (1609–1675) and Christian V (1646– 1699). In 1660, Gijsbrechts was accorded membership in the prominent, influential Guild of St. Luke. Over his career...
