The objective of this study was to assess the suitability of using multidirectional pin-on-disk (POD) testing to characterize wear behavior of retrieved ultrahigh molecular weight polyethylene (UHMWPE). The POD wear behavior of 25 UHMWPE components, retrieved after 10 years in vivo, was compared with 25 that were shelf aged for 10-15 years in their original packaging. Components were gamma ster...

plants gums, hydrophilic colloids, hydrocolloids, mucilages and hydrophilic polymers are compounds that can produce gel. coating materials which applied on food products increased shelf life of food by affecting water loss, gas exchange, oxidation process and decreasing the food spoilage and affect shelf life of food products. coating material could carry antioxidant, antibacterial and/or other...

It is, thus, not surprising that English education has gained more attention than ever and there also has been a growing amount of interest in learning English online. Although there are a good number of ESL/EFL E-learning websites available, many of them are poorly designed technologically and/or pedagogically. It is true that technology, such as human-computer interaction (HCI) and computer-m...

This study considers the ongoing “grammar correction debate” in second language writing by examining how a focus on formal accuracy would affect the revising processes of ESL writers and the students’ written products. A case study approach was used to find out how two ESL students would respond in the two different rewriting situations: (a) when there is no explicit expectation for them to pro...

For marine top predators like seabirds, the oceans represent a multitude of habitats regarding oceanographic conditions and food availability. Worldwide, these marine habitats are being altered by changes in climate and increased anthropogenic impact. This is causing a growing concern on how seabird populations might adapt to these changes. Understanding how seabird populations respond to fluct...

This paper forms part of a broader overview of biodiversity of marine life in the Gulf of Maine area (GoMA), facilitated by the GoMA Census of Marine Life program. It synthesizes current data on species diversity of zooplankton and pelagic nekton, including compilation of observed species and descriptions of seasonal, regional and cross-shelf diversity patterns. Zooplankton diversity in the GoM...

Today‟s improvement of software development processes is heavily dependent on supporting CASE tools, which contain the knowledge about the developed products along with process knowledge used to track and verify the process itself. The commercial of-the-shelf (COTS) tools are usually customized to fit the local environment and process. Such customization includes modifying statuses, re-design p...
