Australian fur seals breed on thirteen islands located in the Bass Strait, Australia. Land access to these islands is restricted, minimising human presence but boat access is still permissible with limitations on approach distances. Thirty-two controlled noise exposure experiments were conducted on breeding Australian fur seals to determine their behavioural response to controlled in-air motor ...

for dissemination) This deliverable reports on the current status of the service implementation for the automatic evaluation of matching tools, and on the final status of those services. These services have been used in the third SEALS evaluation of matching systems, held in Spring 2012 in coordination with the OAEI 2011.5 campaign. We worked mainly on the tasks of modifying the WP12 BPEL work-...

In 1988 and 1989, thousands of harbor seals (Phoca vitulina) died in the North Sea from phocine distemper infection. The morphology of thyroid glands from 40 harbor seals found dead on the North Sea coastlines of Schleswig-Holstein, Federal Republic of Germany, during an epizootic of phocine distemper, was compared with the morphology of thyroid glands from five healthy harbor seals collected i...

This study explores how third-party assurance seals, a privacy service provided by vendors to mitigate customers’ fears, has an impact on on-line customer satisfaction and repeat-purchase intention. It asks the following research questions: Do assurance seals influence on-line service experience? If so, how do they affect consumers’ satisfaction and repeat-purchase intention? The study shows, f...

INTRODUCTION Four species of seals live in association with sea ice in Alaska; these are the ringed seal (Phoca hispida), spotted seal (P. largha), bearded seal (Erignathus barbatus), and ribbon seal (Histriophoca fasciata or Phoca fasciata). Ribbon seals, the focus of this paper, range from the Sea of Japan and the Sea of Okhotsk eastward into the Bering Sea and northward into the Chukchi Sea....

let $r$ be an associative ring with identity and $z^*(r)$ be its set of non-zero zero divisors.  the zero-divisor graph of $r$, denoted by $gamma(r)$, is the graph whose vertices are the non-zero  zero-divisors of  $r$, and two distinct vertices $r$ and $s$ are adjacent if and only if $rs=0$ or $sr=0$.  in this paper, we bring some results about undirected zero-divisor graph of a monoid ring ov...

The use of abradable and rub tolerant polymer seals to reduce leakage between rotating and stationary members in centrifugal compressors and steam turbines has increased over the years. Abradable materials such as mica-filled tetrafluoroethylene (TFE), nickel graphite, and aluminum alloy containing silicon/polyester are the most commonly used and have gained acceptance in the marketplace. This ...

Northern fur seals breeding on the Pribilof Islands are characterized by pelagic migrations that begin each fall and last approximately eight months. Previous studies have examined the early phases of the migration with respect to timing, location, and effects of ocean surface currents on movement. We used satellite telemetry and remotely sensed satellite data to examine relationships between o...

The aim of this study was to compare the effect of treatment with lamotrigine (LTG) or carbamazepine (CBZ) on health-related quality of life (HRQOL) and to demonstrate the use of the SEALS Inventory as a comparative tool in clinical trials. Two hundred and sixty patients with newly diagnosed epilepsy were randomized to 48 weeks of treatment with LTG (n = 131) or CBZ (n = 129). HRQOL was measure...

Many phocid seals are expert divers that remain submerged longer than expected based on estimates of oxygen storage and utilization. This discrepancy is most likely due to an overestimation of diving metabolic rate. During diving, a selective redistribution of blood flow occurs, which may result in reduced metabolism in the hypoperfused tissues and a possible decline in whole-body metabolism to...
