BACKGROUND The present study was designed to evaluate load carriage performance at extremely high altitudes with different loads and walking speeds in terms of physiological evaluation. The degree of maximum oxygen consumption changes at high altitudes was also examined. METHODS Twelve Indian Army soldiers were acclimatized at altitudes of 3,505 m and 4,300 m. They walked for 10 minutes on a ...

Alternating a resistance exercise with a plyometric exercise is referred to as "complex training". In this study, we examined the effect of various resistive loads on the biomechanics of performance of a fast stretch-shortening cycle activity to determine if an optimal resistive load exists for complex training. Twelve elite rugby players performed three drop jumps before and after three back s...

Lysinuric protein intolerance (LPI) is an autosomal recessive defect of diamino acid transport characterised by massive diaminoaciduria, especially lysinuria, with hyperammonaemia after heavy nitrogen intake. The defect has previously been demonstrated in the kidney, and is probably present in the liver cells. To evaluate the effect of the LPI gene on the net intestinal absorption of the diamin...

The physical training undertaken by athletes is one of a set of lifestyle or behavioural factors that can influence immune function, health and ultimately exercise performance. Others factors including potential exposure to pathogens, health status, lifestyle behaviours, sleep and recovery, nutrition and psychosocial issues, need to be considered alongside the physical demands of an athlete's t...

Abstract: Crane hook is a curved beam. Hooks are employed in heavy industries to carry tones of loads safely. These hooks have a big role to play as far as the safety of crane loaded is concerned. With more and more industrialization the rate at which these hooks are forged are increasing. This project is carried out to study the stress variation in crane hooks for different cross sections such...

This paper presents a radio-frequency (RF) transceiver designed, using a standard 0.18 μm CMOS process, for operation in the 2.4 GHz ISM band. The receiver has a sensivity of -64 dBm and consumes 3.5 mW from a 1.5 V supply. The RF transmitter delivers an output power of +11 dBm (15 mW) with a power consumption of 45 mW. These features make the RF transceiver suitable to be integrated in microsy...

Addressing the challenge of packet transmission in a wireless soft real-time system, we present ve splitting protocols that take packet deadlines into account. With them, connectionless service with real-time QoS guarantees at the MAC layer can be ooered. Three protocols are blocked access and two are free access algorithms. Mathematical models are developed and results compared with simulation...
