background: the objective of this study was to determine the heart rate and oxygen consumption of the elderly whilst frying. methodology: in 2010, a total of 31 subjects (11 males and 20 females) from sg. merab, selangor were participated in this study. they were aged between 60 to 83 years with a mean age of 67.06 years. they were asked to perform five minutes frying task and data were measure...

Despite the great potential of fluorescence microscopy, its application to date has largely been in the study of biological specimens. It will be shown that conventional fluorescence microscopy provides an invaluable tool with which to study the photophysics of polymer-supported luminescence-based oxygen sensors. The design of the imaging system, the measurement methods, and the data analysis u...

An optical dual sensor for oxygen and temperature is presented that is highly oxygen sensitive and covers a broad temperature range. Dual sensing is based on luminescence lifetime measurements. The novel sensor contains two luminescent compounds incorporated into polymer films. The temperature-sensitive dye (ruthenium tris-1,10-phenanthroline) has a highly temperature-dependent luminescence and...

BACKGROUND A new forehead noninvasive oxygen saturation sensor may improve signal quality in patients with low cardiac index. OBJECTIVES To examine agreement between oxygen saturation values obtained by using digit-based and forehead pulse oximeters with arterial oxygen saturation in patients with low cardiac index. METHODS A method-comparison study was used to examine the agreement between...

A laminated Pd-Cu alloy/C/Nafion multilayer was prepared to sense O2 atmosphere in a metal-air structure. As matrix, palladium doped with various amounts of copper conduct preliminary test optimum response, and four compositions, Pd, Pd8Cu2, Pd6Cu4, Pd5Cu5, were selected as the candidate electrodes. It found that Pd6Cu4/C electrode showed higher sensitivity for all According phase identificatio...

routing in wireless sensor networks (wsns) is a very challenging task due to the large number of nodes, their mobility and lack of proper infrastructure. since the sensors are battery powered devices, energy efficiency is considered as one of the main factors in designing routing protocols in wsns. most of energy-aware routing protocols are mere energy savers that attempt to decrease the energy...
