The availability of various koi pond pump products is marketed with kinds, types, and advantages. This diversity makes it difficult for business owners to determine a product that suits their needs. consideration the in question form an electric submersible or ESP. One method can be used selection AHP (Analytical Hierarchy Process) method. study uses assisted by expert choice software. From res...

Rhythm disturbances and mechanical function suppression proper to the acute heart failure in the case of cardiomyocyte calcium overload are simulated in a mathematical model of cardiomyocyte electromechanical activity. Particular attention is paid to the overload caused by diminished activity of the Na-K pump. It is shown in the framework of the model that myocardium mechanics may promote arrhy...

Solar panels are an alternative power generation system sourced from the absorption of solar energy. The energy absorbed will convert into a source electricity. panel's drives alternating current (AC) water pump. This study aims to determine performance AC pump by utilizing electrical panels. parameters measured voltage, current, and generated at varying times. used with capacity 100 WP were co...

The efficiency of conversion of electrical power into fluidic power in an electrohydrody-namic (EHD) pump depends on the bulk fluid velocity. An analytical formulation is developed for calculation of the efficiency of an EHD pump, with and without the presence of a superimposed flow due to an externally imposed pressure gradient. This formulation is implemented into a numerical model, which is ...

The electrical load from irrigation pumps is an important part of the overall electricity demand in many agricultural areas of the U.S. west. The date the pumps turn on and the total electrical load they present over the summer varies from year to year, partly because of climate fluctuations. Predicting this variability would be useful to electricity producers that supply the region. This work ...

This paper analyzes the dynamic properties of a submersible drogue for which buoyancy control is implemented by a flexible membrane and pneumatic actuation. It is shown how a simple on/off switching algorithm tuned on the basis of depth measurements and an estimated depth velocity can be used to achieve accurate depth control with small fluctuations. The switching control makes the pneumaticall...

Water distribution networks are a fundamental part of any modern city and their daily operations constitute a significant expenditure in terms of energy and maintenance costs. Careful scheduling of pump operations may lead to significant energy savings and prevent wear and tear. By means of computer simulation, an optimal schedule of pumps can be found by an optimisation algorithm. The subject ...

Electrical noise will be present in the operating room even under ideal circumstances. The addition of the cardiopulmonary bypass machine to the other machinery in the operating room introduces one more source of electrical noise. Identifying and managing this interference may aid in reducing artifactual signals on the electrocardiogram (EKG) monitor. If electrical interference occurs during th...

The Electrical Activity of the Heart and Brain Under Acute Experimental Anoxia: The Protective Effect of Polarizing Solutions • Acute anoxia was produced in 80 dogs under anesthesia with sodium pentobarbital. Respiration was maintained with a Palmer's pump through an endotracheal tube. The anoxia was produced by stopping the pump and occluding the endotracheal tube. Polarizing solution (glucose...
