nano-sized titanium dioxide tio2 powder was prepared by new wet chemical route from its precursor titanium (iv) chloride (ticl4) as precursor with isopropoxy alcohol in presence of nitric acid under ambient condition. their morphologies, phase compositions and components of the tio2 nanoparticles were characterized by transmission electron microscopy (tem), field emission scanning electron micr...

purpose the aim of this study was to compare the levels of serum immunoglobulin (iga, igm, igg), testosterone and cortisol in semi-endurance elite runners during general preparation and competition phase of training. methods thirteen semi-endurance elite male runners with an average age of 18.92±1.7 years volunteered to take part in this study. the runners participated in the selected training ...

background: potassium citrate (k‑cit) is one of the medications widely used in patients with urolithiasis. however, in some cases with calcium oxalate (caox) urolithiasis, the significant response to alkaline therapy with k‑cit alone does not occur. there is scarce published data on the effect of magnesium chloride (mg‑cl2) on urolithiasis in pediatric patients. this study aimed to evaluate the...

conclusions in issns, bone strength recovered one month after terminating stx. in igan, bone strength recovered 10 months after tapering of stx. results in issns, the bmd and s-alp levels were significantly lower in phase 1 than in phase 0; however, scores and levels returned to baseline in phase 2. in igan, bmd was significantly lower in phase 2 than in phase 0 while s-alp levels were signific...

background: women with polycystic ovary syndrome have lower pregnancy rates, possibly due to the decreased uterine  receptivity.successful implantation depends on protein networks that are essential for cross-talk between the embryo and endometrium.apolipoprotein a1 has been proposed as a putative anti-implantation factor. in this study, we evaluated apolipoprotein a1 expression in human endome...

after designing and constructing a coalescence cell, drop/interface coalescence phenomenon was studied in the absence and presence of single surfactant.two surface active agents of sodium dodecyl sulfate and 1-decanol were used. distilled water was used as dispersed phase. toluene, n-heptane and aqueous 60% (v/v) of glycerol were selected as continuous phases, separately. it was found that the ...

the mechanism and the parameters affecting the matrix-fibril morphology in melt spun polyblend fibers are discussed. the properties of polymeric blends depend considerably on their final morphologies. blending of two miscible polymers, normally gives rise to formation of a single-phase morphology while blending of two immiscible polymers can create a two or three (in case of using compatibilize...

Profilometry by fringe projection is an optical metrology technique implemented projecting a sinusoidal grating onto a three-dimensional surface, where the resulting deformed grating image represents the object’s height distribution modulated in phase. Fringe projection can be implemented as a phase shifting process or as a one-frame method. In this work, both approaches are compared using a co...

ABSTRACT: Radar is gaining increasing credibility as a technique for rapid and accurate topographic mapping. Precision and accuracy of elevation and ground displacement assessed from Interferometry SAR (InSAR) depend essentially on phase difference or interferogram quality. The phase noise degrades the visual quality of the interferogram and increases the error in phase unwrapping results. Many...
