BACKGROUND Influenza causes substantial morbidity and annual vaccination is the most important prevention strategy. Accurately measuring vaccine effectiveness (VE) is difficult. The clinical syndrome most closely associated with influenza virus infection, influenza-like illness (ILI), is not specific. In addition, laboratory confirmation is infrequently done, and available rapid diagnostic test...

           3-(2’-n-butylbenzofuran-3’-yl)-5-aryl-4, 5-dihydro-1H-pyrazoles (4a-4k) have been synthesized. The synthesized products have been assayed for their antimicrobial activity against Gram+ve,      Gram-ve bacteria and fungi. All the synthesized products were assigned with IR, 1HNMR, Mass Spectra, TLC, and elemental analysis. Some of the products showed moderate activi...

1. Introduction Education has long been touted as an important application area for immersive virtual environments (VEs). VEs can allow students to visualize and interact with complex three-dimensional (3D) structures, perform virtual " experiments, " view scenes with natural head and body movements, and experience environments that would be otherwise inaccessible because of distance (the surfa...

This paper addresses the implementation of complex multiple degree of freedom virtual environments for haptic display. We suggest that a physics-based approach to rigid body simulation is appropriate for hand tool simulation, but that currently available simulation techniques are not sufficient to guarantee successful implementation. We discuss the desirable features of a VE simulation, specifi...

A Virtual Environment (VE) is a computer-generated setting in which a participant is presented with simulated conditions that can be controlled to varying degrees. These simulations serve several purposes, including research, entertainment, and training. VE technology has already been shown to have applications in immersion therapy for phobia patients (Harris, Kemmerling, and North, 2002), and ...

In the rat, a mostly nocturnal animal, activity, body temperature and metabolic rate increase during the dark hours of the day. Since all these variables are known to influence breathing, it is expected that also pulmonary ventilation (VE) will present a circadian pattern. In rats chronically instrumented for measurements of body temperature and activity by telemetry, carbon dioxide production ...

The role of virtual environments (VE) is crucial in efficient design and operation of unmanned vehicles. VEs are extensively used in operator training for tele-operation, planning using programming by demonstration, and hardware and software design. VE for unmanned sea surface vehicles (USSV) requires a six degree of freedom dynamics simulation in the time domain. In order to be interactive, th...

BACKGROUND Sudden death is the leading cause of death in Chagas disease (CD), even in patients with preserved ejection fraction (EF), suggesting that destabilizing factors of the arrhythmogenic substrate (autonomic modulation) contribute to its occurrence. OBJECTIVE To determine baroreflex sensitivity (BRS) in patients with undetermined CD (GI), arrhythmogenic CD with nonsustained ventricular...
