Although many researchers have studied the flow hydraulics in compound channels, there are still many complicated problems in determination of their flow rating curves. Many different methods have been presented for these channels but extending them for all types of compound channels with different geometrical and hydraulic conditions is certainly difficult. In this study, by aid of nearly 400 ...

The large-conductance Ca(2+)-activated K(+) (BK(Ca)) channels modulate vascular smooth muscle tone but the role of BK(Ca) channels in regulation of retinal circulation remains unclear. In the present study, we examined the effects of BMS-191011 and NS 1619, openers of BK(Ca) channels, on rat retinal blood vessels in vivo. Male Wistar rats (8- to 10-week-old) were anesthetized with pentobarbital...

propene dissociation channels were characterized by ab initio ccsd(t)/6-311++g(d,p) calculations. inthis work the detailed mechanism of propene dissociation to c2h4+ch2, c2h2+h+ch3, c2h2+ch4 andc3h3+h2+h have been investigated. according to our calculations, ten fragments can be classified intofive dissociated channels. our results point out that two mechanisms come into play in the h2 eliminat...

Sensitivity and diagnostic capabilities of magnetic resonance imaging (MRI) are dictated by the design radio frequency (RF) receive coils. They must possess several key characteristics, such as a high signal-to-noise ratio (SNR), for image quality enhancement multiple channels scan time reduction. Artificial materials with tailored properties, metasurfaces, when used RF coils, have been shown t...

Planar lipid bilayer recordings were used to study Ca channels from bovine cardiac sarcolemmal membranes. Ca channel activity was recorded in the absence of nucleotides or soluble enzymes, over a range of membrane potentials and ionic conditions that cannot be achieved in intact cells. The dihydropyridine-sensitive L-type Ca channel, studied in the presence of Bay K 8644, was identified by a de...

Sick sinus syndrome (SSS) encompasses a group of disorders whereby the heart is unable to perform its pacemaker function, due to genetic and acquired causes. Tachycardia‑bradycardia syndrome (TBS) is a complication of SSS characterized by alternating tachycardia and bradycardia. Techniques such as genetic screening and molecular diagnostics together with the use of pre-clinical models have eluc...

In a polymer membrane fuel cell more than half of the chemical energy of hydrogen is converted to heat during generation of electricity. This causes an increase in the cell temperature. The Cooling field design has a significant role in cell cooling. The cell's performance and stability are reduced due to inappropriate heat dissipation. In this paper, the cooling flow and heat transfer in cooli...

Introduction: It has recently been suggested that the KATP channel subunits Kir6.x and BKCa channels exist in the endoplasmic reticulum of cardiomyocytes and neurons. Our previous studies showed the electrophysiological behavior of cation channels in the rough endoplasmic reticulum (RER) of rat hepatocytes. Therefore, we hypothesized that KATP channels and Ca2+-activated potassium channels m...
