Solid oxide fuel cells (SOFCs) are promising electrochemical energy conversion devices owing to their high power generation efficiency and environmentally benign operation. Micro-tubular SOFCs, which have diameters ranging from a few millimeters to the sub-millimeter scale, offer several advantages over competing SOFCs such as high volumetric power density, good endurance against thermal cyclin...

a case of renal tubular acidosis (rta) who had gradual onset of paralysis of lower extremities and persisted for a long time is presented. his primary workups were mistaken for muscular dystrophy. eventually, an abdominal ultrasonography revealed small stones in both of the kidneys and his workup for the stones were in favor of distal renal tubular acidosis and advanced rickets with hypokalemia...

Flow sensing by primary cilia of the epithelial cells is involved in cystogenesis in polycystic kidney disease. We investigate whether a similar mechanism applies to the pathogenesis of cyst-like tubular dilatation induced by ureteral obstruction in mice. Robust proliferation occurs in the obstructed tubules when urine flow is interrupted as well as in the repairing tubules when urine flow is r...

Epithelial inclusions were detected in myocardium of a 2-month-old male Holstein calf. Microscopically,nonpurulent myocarditis along with focal tubular and acinar structures covered with cuboidal epithelial cellswas seen in the myocardium. Most tubular and acinar structures stained with Masson’s trichrome were foundto be surrounded with a dense collagen. Tubular and acinar structures had PAS po...

Membranes offer remarkable attributes such as possessing small equipment footprints, having high efficiency and are environmentally friendly, with carbon membranes progressively investigated for gas separation applications. In this study, carbon tubular membranes for CO2 separationare prepared via the dip-coating method with P84 co-polyimide as the carbon precursor. The prepared membranes were ...

An increase in Na+/glucose cotransport upstream to the macula densa might contribute to the increase in single nephron GFR (SNGFR) in early diabetes mellitus by lowering the signal of the tubuloglomerular feedback, i.e., the luminal Na+, Cl-, and K+ concentration sensed by the macula densa. To examine this issue, micropuncture experiments were performed in nephrons with superficial glomeruli of...

Background & Objectives: Tubular adenomas are rare benign epithelial tumours of breast affecting predominantly females of child bearing age group. Till now, very small number of cases have been reported in the literature. Present study was carried out to evaluate the clinico-pathological features of tubular adenoma cases diagnosed during three years study period along with discussion of possibl...

the specificity of gentamicin for vitamin e deficiency-associated oxidative stresses in the renal proximal convoluted tubules is apparently related to its ability to increasingly facilitate generation of radical species in mitochondria. to determine the ways in which vitamin e manage the currently processes, we conducted a prospective study aimed to investigate the tubular preserving effect of ...

steam reforming is one of the most important processes for producing hydrogen from hydrocarbon fuels such as lpg and has attracted much attention due to its high efficiency and economy. in this study, the lpg steam reforming reaction was investigated on nickel catalysts supported on four various zeolites (h-y, na-y, hzsm5 and ferrierite). the catalytic tests were performed in a tubular fixed be...

background diatomite coated by nanoparticles of copper and zinc mixed oxides were used to investigate catalytic oxidation of carbon monoxide. objectives aim of this paper was to investigatediatomite performance as a supporting host to confine the cuo and zno nanoparticles and its catalytic activity for carbon monoxide oxidation. materials and methods the prepared catalysts were characterized by...
