A computer model for prediction and analysis of an oil-flooded single screw compressor performance is developed. The model includes suction preheat, pressuri ~~.tion of the gas in the control volume during the suction closure process, flowage of gas and oil mixture through discharge port, leakage of gas and oil. It considers the effect of oil-injection rate, clearances and length of leaka~e pat...

The author's interest was aroused when he came across a large leather bound volume in the museum of the USS Constitution, which turned out to be the Physical and chirurgical transactions ofDr Peter St. Medard on board the US Frigate New-York from 1802-1803. It provided him with "a unique opportunity to study the effect of day-to-day medical practice on an early modem population". In that respec...

Sir, I was recently on call for nephrology, and something happened. I was rung by a first year junior doctor at 1 am, saying that a patient's 'MEWS score was 6'. The patient had had a renal transplant that day. A score of 6 is very high. It should trigger a rapid senior review, and possible intensive care re-ferral. Modified early warning score (MEWS) is an electronic early warning score based ...

of discharge. The study aimed to calculate a hospital readmission rate, to investigate the timing of readmissions, and to identify risk factors associated with readmission. The readmission rate was 27% with the majority of readmissions occurring within three months after discharge, suggesting the need for investigation of such early readmissions. The three factors found to predict readmission w...

Objectives: To investigate the details of patients' status on admission and at discharge at our hospital, to compare the ambulatory group and non-ambulatory group at discharge, and to assess the factors associated with ambulatory ability at discharge in patients aged ≥ 90 years with proximal femoral fractures (PFFs). Patients/Materials and Methods: Twenty patients admitted to our hospital for r...

This research aims to study jet downstream scour model under the influence of changes of water level. It also studies and analyzes different parameters and components of diffusion of submerged jet flow in an acceptor fluid and scour hole dimensions. To achieve the objectives, a physical model was made in proportion to the research title. With the Froude number increasing in a nozzle discharge, ...

The rate coefficient for dielectronic recombination (DR) of Ne-like Fe forming Na-like Fe was measured employing the merged electron-ion beams technique at the heavyion storage-ring TSR of the Max-Planck-Institut für Kernphysik in Heidelberg, Germany. In the electron-ion collision energy range of 240–840 eV the merged-beams recombination rate coefficient is dominated by DR associated with 2s 2p...
