The purpose of this research was to identify possible predisposing neuromuscular factors for knee injuries, particularly anterior cruciate ligament tears in female athletes by investigating anterior knee laxity, lower extremity muscle strength, endurance, muscle reaction time, and muscle recruitment order in response to anterior tibial translation. We recruited four subject groups: elite female...

236 Performance Characteristics of a Third Generation Portable Radionuclide Identifier Ronald M. Keyser and Timothy R. Twomey ORTEC, 801 South Illinois Avenue, Oak Ridge, TN 37830 ABSTRACT The continuing need for a hand-held, portable radionuclide identifier for use in countering illicit nuclear trafficking and in positive identification of radioactive materials, benign or threat, has fostered ...

Commercial acceptance of microstructured polymer optical fibres (MPOFs) is dependent on their delivery of an acceptable combination of loss and bandwidth. This paper describes recent advances in one attempt at quantifying multimode MPOF performance with a view to developing various graded index MPOFs (GIMPOFs) using structures made up of either air or polymer-filled holes.

To the Editor:—I have concern about the article entitled “Performance Characteristics of Five New Anesthesia Ventilators and Four Intensive Care Ventilators in Pressure-support Mode: A Comparative Bench Study,” which appeared in the November 2006 issue of ANESTHESIOLOGY. Several statements made in the article are incorrect, and we appreciate an opportunity to set the record straight. In table 1...

Due to the ongoing massive growth of the global Internet, the rising integration of Voice over IP (VoIP) services and the Fixed Mobile Convergence (FMC), the IPv6 protocol and the Session Initiation Protocol (SIP) are key technologies for the realization of next generation communications. For both topics, IPv6 and SIP, a lot of self-contained research has been done. However, the challenge of SI...

BACKGROUND Regular monitoring of dialysis grafts is recommended, but the value of dialysis graft blood flow monitoring and venous pressures in predicting subsequent outcomes are controversial. METHODS Over a period of one month, we performed simultaneous flow and venous pressure monitoring in 71 dialysis patients with polytetrafluoroethylene (PTFE) grafts. These patients were prospectively fo...

VMware ESX Server offers three choices for managing disk access in a virtual machine—VMware Virtual Machine File System (VMFS), virtual raw device mapping (RDM), and physical raw device mapping. It is very important to understand the I/O characteristics of these disk access management systems in order to choose the right access type for a particular application. Choosing the right disk access m...

emergency physicians face numerous questions regarding proper management of patients and selection of the best laboratory test or imaging every day. knowledge on screening performance characteristics of the diagnostic tools used in this department plays an important role in finding the answers to these questions. we assessed these characteristics in the previous parts of educational article ser...
