BACKGROUND Staphylococcus aureus is a common human pathogen that can colonise the respiratory tract and cause infection. Here we investigate the risk factors associated with nasopharyngeal carriage of S. aureus (including methicillin-resistant S. aureus [MRSA]) in Vietnam. METHODS Between February and June 2012, nasal and pharyngeal swabs for S. aureus culture, and demographic and socioeconom...

This article describes the current status of the Deep Space Network advanced systems research into ionospheric calibration techniques, based on Global Positioning System (GPS) data. A GPS-based calibration system is planned to replace the currently used Faraday rotation method by 1989. The SERIES receiver system used in this research determines the differential group delay of signals transmitte...

PHLPP2 (PH domain leucine-rich repeat protein phosphatase 2) terminates Akt and protein kinase C (PKC) activity by specifically dephosphorylating these kinases at a key regulatory site, the hydrophobic motif (Ser-473 in Akt1). Here we identify a polymorphism that results in an amino acid change from a Leu to Ser at codon 1016 in the phosphatase domain of PHLPP2, which reduces phosphatase activi...

The reliable transmission of Federal Standard CELP 1016 encoded speech over very noisy communication channels is investigated. First, the interframe and intraframe redundancy present in the CELP 1016 parameters is quanti ed using second-order Markov chains. It is shown that over one-quarter of the CELP bits in every frame of speech are redundant. An unequal error protection (UEP) coding scheme,...

A system is proposed that is capable of identifying the true originator of an email message. This information can be combined with existing whitelist and blacklist technology to provide an effective anti-spam system. The approach is to store validation information that can be traced to the sender and to utilize a “Reachback URL” in the message to access the validation information. The approach ...

Os avanços na tecnologia fizeram fabricantes desenvolverem peças mais complexas em pouco tempo com uma boa qualidade. Essas são feitas por tecnologias de usinagem a laser, plasma, onde elas algumas dessas bem estabelecidas manufatura. Neste trabalho foi utilizado pesquisa bibliográfica, sob abordagem campo que o processo mecanizado mostrando ar comprimido como gás corte. Foi analisado os parâme...
