abstractinduced total pressure by flow, including mean and fluctuating components, around a selected chute block in saf stilling basins downstream of an ogee spillway was studied. several pressure holes were selected on various faces of a selected chute block to get enough information regarding the total pressure field. this paper reports the results of an experimental work and measurement of m...

conclusions obtained results demonstrate significant differences between intraneural and perineural injection pressures in the median, ulnar, and radial nerves. intraneural injection pressures show low specificity but high sensitivity suggesting that pressure monitoring might be a valuable tool in improving the safety and efficacy of peripheral nerve blockade in regional anesthesia. peripheral ...

Background Certain occupations are at greater risk of stress and depression than others. In particular, occupations related to too much or too little work, having to make too many decisions, having very little control over decisions, time pressures and deadlines, excessive and inconvenient working hours, highly repetitive work and lack of job variety, the necessity to work fast, job insecurity ...

BACKGROUND Measurements of maximal voluntary inspiratory (PI(max)) and expiratory (PE(max)) pressures are used in the management of respiratory muscle disease. There is little data on the appropriate reference range, success rates, or repeatability of PI(max) and PE(max) in children or on methodological factors affecting test outcomes. OBJECTIVES To determine PI(max) and PE(max) in healthy ch...

in this study, mass transfer coefficients (mtc’s) of natural gas components during hydrate formation are reported. this work is based on the assumption that the transport of gas molecules from gas phase to aqueous phase is dominant among other resistances. several experiments were conducted on a mixture of natural gas at different pressures and temperatures and the consumed gas was monitored an...

culture and folk beliefs are noticeably reflected in persian literature in general and in its poetry in particular. paying attention to such beliefs is sometimes useful while correcting a text and identifying a preferred record. on this basis, the present article examines two verses of sanai’s hadiqa al-haqiqa and offers the proposed correction. verses from other poets have been presented to fu...

Modelling studies are presented of positive streamers developing at various pressures in air in a point-to-plane discharge geometry. The modelling results emphasize that the quenching of the singlet excited states of molecular nitrogen emitting photoionizing radiation is responsible for non-similar behaviour of streamers at pressures higher than approximately 30 Torr. Our modelling results are ...
