Numerical simulation of the stalled flow within a vaned centrifugal pump
(PROFESSIONAL ENGINEERING PUBLISHING LTD, 2004)
The main goal of the present work is to analyse the numerical simulation of a centrifugal pump by solving Navier-Stokes equations, coupled with the 'standard k-epsilon' turbulence model. The pump consists of an impeller ...
Heart rate turbulence: An additional parameter in determining the need for mechanical relief of mitral stenosis?
(I C R PUBLISHERS, 2007)
Background and aim of the study: Heart rate turbulence (HRT) is a relatively newer parameter which has predictive value for mortality and severity in a variety of cardiovascular diseases. The study aim was to investigate ...
Sequential ultrasonic leaching of strontium from sediments
(GORDON BREACH PUBLISHING, TAYLOR & FRANCIS GROUP, 2001)
The effects of ultrasonic excitation on the sequential leaching of Sr from sediments have been investigated. The sequential leaching scheme of Tessier partitions metals in sediments into exchangeable, carbonate bound, oxide ...
Failure strength of woven glass fiber-epoxy composites pinned joints
(SAGE PUBLICATIONS LTD, 2003)
In this paper, mechanical behavior and damage development of pin-loaded woven glass fiber-epoxy composites have been observed numerically and experimentally. Parametric studies have been performed to evaluate the effects ...
Prostaglandin E-2 Via Steroidogenic Factor-1 Coordinately Regulates Transcription of Steroidogenic Genes Necessary for Estrogen Synthesis in Endometriosis
(ENDOCRINE SOC, 2009)
Context: Products of at least five specific steroidogenic genes, including steroidogenic acute regulatory protein (StAR), which facilitates the entry of cytosolic cholesterol into the mitochondrion, side chain cleavage ...
Modification and characterisation of terpolymer maleic anhydride-styrene-vinyl acetate by poly(ethylene adipate) copolymer
(MANEY PUBLISHING, 2007)
In the present paper, poly(ethylene adipate) (PEA) copolymer of ethylene glycol/adipic acid was synthesised by the polycondensation in the status without an initiator at 180 degrees C for 5 h. It reacted with the PEA ...
Long-wavelength broad band infrared photodetector using four asymmetric quantum wells
(ELSEVIER SCIENCE BV, 2007)
A theoretical investigation of GaAs/AlGaAs infrared detector consisting of four asymmetric quantum wells is presented. Each well is designed to yield absorption and a photoresponse at peak wavelengths of 7.9, 9.2, 10.4, ...
Muscle ischaemia in rats may be relieved by overload-induced angiogenesis
(CAMBRIDGE UNIV PRESS, 2002)
Alleviation of muscle ischaemia by improving capillary supply has proved difficult, possibly reflecting the inability to substantially increase blood flow. We reasoned that muscle overload, which induces angiogenesis in ...
Flotation and entrainment behavior of minerals in talc-calcite separation
(BLACKWELL PUBLISHING, 2005)
The main aim of a flotation process is to recover the valuable part of the ore with minimum gangue contamination by different mechanisms, such as entrainment. In this study, the flotation rate and recovery of talc and ...
Hopelessness and Depression in Cancer Patients
(UNIVERSITATSVERLAG ULM GMBH, 2009)
The hopelessness and depression of cancer patients (124) who were admitted to an oncology hospital's medical oncology ward were investigated. Data were collected with using a personel information form, Beck hopelessness ...
