information on animal daily forage needs is essential for an estimation of rangeland grazing capacity. accordingly, weight and animal unit equivalent (aue) for each individual class of animal should be determined. live weights of baloochi sheep as based on average live weights of 3 and 4 year old ewes were determined. five herds of baloochi breed sheep were selected for the task. in each herd, ...

High power and particle deposition on target materials are encountered in many applications including magnetic and inertial fusion devices, nuclear and high energy physics applications, and laser and discharge produced plasma devices. Surface and structural damage to plasma-facing components due to the frequent loss of plasma confinement remains a serious problem for the Tokamak reactor concept...

A litter of four cats, born and raised in a soundproofed chamber, was studied in an attempt to determine which, if any, features of the auditory-nerve response from routinely available cats might be due to the chronic effects of noise exposure. Two features of routine-normal response were especially suspect in this regard: (1) a "notch" in the distribution of single-unit thresholds centered at ...

The influence of the degree grinding particles growing raw materials during electric discharge extraction on quality obtained extracts was studied. Each electro-discharge contributes to a part material, which is confirmed by granulometric analysis. particle size material should be controlled, since excessive results in cloudy, difficult clarify and poorly filtered. design chamber proposed, grou...

In the proposed centrifugal filtration device, a filter is mounted in center of chamber. The particles move towards centrifuge wall away from under force, so cake unlikely to accumulate here. working fluid injected continuously, feed pressure higher than discharge pressure, which compels light-phase leave through as filtrate. filtrate flux rate and movement chamber device were investigated usin...

This work examines a long duration Hall thruster start transient caused by the vacuum chamber environment. During operation of a cluster of four Hall thrusters, large anode discharge fluctuations, visible as increased anode current and a more diffuse plume structure, occur in an apparently random manner. For single thrusters, the transient appears as a smoothly decaying elevated anode current w...

introduction: delivering maximum dose to tumor and minimum dose to normal tissues is the most important goal in radiotherapy. according to icru, the maximum acceptable uncertainty in the delivered dose compared to the prescribed dose should be lower than 5%, and this is because of the relationship between absorbed dose, tumor control and normal tissue damage. absorbed dose accuracy is investiga...

A continuous oxygen plasma operating at a radio frequency power of 800 W and a pressure of 2 mTorr has been created in a helicon diffusion reactor used for the deposition of silicon dioxide films. An energy selective mass spectrometer and a Langmuir probe attached to the wall of the silica covered aluminum diffusion chamber below the source have been used to characterize the plasma @ion energy ...
