A model was conceptualised to emulate the behaviour of coastal water during high and low tides and the impact of the pump failure in present and projected future scenarios was estimated on it. The model was validated before being used for failure scenario simulation. The study indicates that potential adverse effects on water quality are imminent in case of sewage pumping station failure and wa...

Acute Respiratory Failure (ARF) is a syndrome characterized by the inability of the respiratory system to maintain adequate arterial O2 and CO2 levels according to the demands of cellular metabolism. ARF may be caused by the failure of the exchanger, lung, organ or pump, or failure of the respiratory muscles. ARF can be classified by the dysfunctional element or the evolution time when the cond...

BACKGROUND Coronary revascularization on the beating heart is an attractive to option conventional coronary artery bypass graft (CABG) but remains controversial. Our study encourages sufficient proper time for decision-making when changing CABG from off-pump to on-pump CABG. We report herein patients who changed from off-pump CABG to on-pump CABG. METHODS A retrospective analysis of 240 patie...

general concept and major emphasis on off-pump coronary artery bypass surgery (opcab) is maintaining quality of care and patient safety while reducing cost and resource utilization. opcab probably avoids the potential complications of cardiopulmonary bypass. however its acceptance depends on clinical and economic outcome. the aim of this study is to compare clinical and economic outcome of off-...

Vacuum pump wear is the most prevalent failure mode of IBA Synthera® automated radiochemistry system. Rebuilding or replacing causes equipment downtime and increases radiation exposure service personnel. We built a dedicated test device to assess new rebuilt pumps prior installation, thus reducing during repairs. The Testbed incorporates microprocessor that actuates pump, valves, pressure senso...

Elevated aldosterone levels induce a spironolactone-inhibitable decrease in cardiac sarcolemmal Na+-K+ pump function. Because pump inhibition has been shown to contribute to myocyte hypertrophy, restoration of Na+-K+ pump function may represent a possible mechanism for the cardioprotective action of mineralocorticoid receptor (MR) blockade. The present study examines whether treatment with the ...

Theoretical and experimental results are reported on the thermal lensing effect caused by the radial thermal gradient present in optically pumped Nd:YAG laser rods. The presented theory is in agreement with the experimental observations. The results reveal that a Nd: YAG rod under pumped light becomes a positive lens with two focal lengths. The temperature dependent variation of the refractive ...

As a hydraulic pump is the power source of system, predicting its remaining useful life (RUL) can effectively improve operating efficiency system and reduce incidence failure. This paper presents scheme for RUL (gear pump) through combination deep convolutional autoencoder (DCAE) bidirectional long short-term memory (Bi-LSTM) network. The vibration data were characterized by DCAE, health indica...

Pathological findings in the heart and particularly in the coronary arteries are reported from 70 patients dying from pump failure after acute myocardial infarction. Fifty of the patients had died in cardiogenic shock, the remainder from refractory congestive heart failure. Three-vessel disease (greater than or equal to 75% occlusion) was present in 68 per cent of the group with cardiogenic sho...

Little is known about the mechanical forces acting on extracorporeal circuit tubing with prolonged roller pump use during extracorporeal membrane oxygenation (ECMO). We examined the time to tubing rupture of three different materials during actual roller pump use, mean and standard deviation (SD) (SD shown in parentheses): Tygon (control) 243.7 h (175.4); LVA 121 h (14.3); and SRT 6.6 h (2.1). ...
