Waste heat recovery is very important, because not only it reduces the expenditure of heat generation, but also it is of high priority in environmental consideration, such as reduction in greenhouse gases. One of the devices is used in waste heat recovery is heat pipe heat exchanger.Anexperimental research has been carried out to investigate the hydrodynamic and thermal performance of a gas...

Essential hyperhidrosis is a well recognized dermatologic and neurologic disorder, characterized by excessive sweating of the eccrine sweat glands. It is also associated with cardiac autonomic dysfunction because sympathetic fibers to eccrine glands of palms of the hand arise from stellate and upper thoracic ganglia, which also innervate the heart. In this study, we investigated cardiac functio...

It was hypothesised that, apart from right ventricular (RV) dysfunction, patients with idiopathic pulmonary fibrosis (IPF) also exhibit left ventricular (LV) impairment, which may affect disease progression and prognosis. The aim of the present study was to evaluate LV performance in a cohort of IPF patients using conventional and tissue Doppler echocardiography. IPF patients exhibiting mild-to...

The objective of this paper is to design, develop and testing of the “Real time implementation of SCADA system for ratio control based bottle filling plant”. This work will provide low operational cost, low power consumption, accuracy and flexibility to the system and at the same time it will provide accurate volume of liquid in bottle by saving operational time. In this work, a prototype has b...

gasoline filling station workers Ansari-Lari et al reported that the sex ratio (proportion male) of offspring of men exposed to petroleum fuel is significantly low as contrasted with controls. If confirmed, this is an important result. It is in contrast with reports of significantly high offspring sex ratios in communities exposed to active seepages of natural gas and oil and to petrochemical a...

AIMS With the purpose of studying left ventricular filling in Chagas' disease (Chd), we evaluated 169 patients with Chd using echocardiography and Doppler and tissue Doppler imaging (TDI). METHODS AND RESULTS The patients were divided into four groups according to the pattern of left ventricular filling: Group 0--normal filling pattern, Group 1--abnormal relaxation, Group 2--pseudonormal flow...

Filling high aspect ratio trenches is an essential manufacturing step for state of the art memory cells. Understanding and simulating the transport and surface processes enables to achieve voidless filling of deep trenches, to predict the resulting profiles, and thus to optimize the process parameters and the resulting memory cells. Experiments of arsenic doped polysilicon deposition show that ...

BACKGROUND A noninvasive system for determining left ventricular (LV) filling pressure may help to improve personalized fluid removal goals in hemodialysis patients. We previously showed that the change in photoplethysmography (PPG) pulse amplitude measured by finger PPG during a Valsalva maneuver correlates with invasively measured left ventricular end-diastolic pressure (LVEDP). This key PPG ...

UBV and JHK photometry of the active singlelined binary II Peg, we performed in 1995, is presented. A method to determine the fraction of the photosphere covered by spots (filling factor) and to check the accuracy of generally assumed values of photospheric parameters has been developed. The procedure is based on the comparison between multiband fluxes and low resolution synthetic spectra weigh...

Amygdaloidal, cavity- and fracture-filling zeolites in Eocene volcanic rocks from the Kuh-e-Aradeh of southern Kahrizak, in the northernmost part of Central Iran have been studied in some detail by optical, chemical analysis, SEM, and XRD techniques. The zeolites identified, in order of their relative time of formation from early to late, are tetranatrolite, analcime, natrolite, mesolite, stilb...
