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...

The microstructure of dual phase steels can be considered as a matrix of ferrite phase reinforced by martensite particles. Recent measurements show that the mechanical properties of the ferrite phase are changed with the distance from the martensite grains. In this paper, a new method has been proposed to consider this phenomenon in finite element modeling of dual phase steels microstructure. I...

In this paper we consider a nonlinear two-phase Stefan problem in one-dimensional space. The problem is mapped into a nonlinear Volterra integral equation for the free boundary.

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...

the applicability of hollow fiber-based liquid phase microextraction (hf-lpme) was evaluated for the extraction and preconcentration of loratadine prior to determination by hplc. in order to obtain high extraction recovery, the parameters affecting the hf-lpme including type of organic phase, ph of the source and receiving phases, stirring rate, extraction time and salt addition were studied an...

development and optimisation of fast, efficient, quantitative, economic and environmentally friendly analytical extraction techniques for the extraction clean up, and pre-concentration in the quantification of 16 usepa priority polycyclic aromatic hydrocarbons (pahs) in contaminated soils have been carried out. three different extraction methods (soxhlet, ultra sonication and mechanical shaking...

iran's proved natural gas reserves are the world's second largest reserves. mainly, because of different climate changes and different reservoirs characterizations, studying the behavior of producing outcome fluids and their transportation, is of major interest. one of the main problems occur in the gas reservoirs is related to the hydrate formation while producing from a well, either in produc...

the aim of this study is to investigate antioxidant enzymes, oxidative stress biomarkers and the acute phase proteins levels for subclinical and clinical pregnancy toxemia and to determine the effect of early diagnosis on the success of curing. according to the results of clinical and biochemical parameters, from 39 ewes, 10 were healthy ewes (control group), 13 ewes had subclinical pregnancy t...

the commercial profile of the amoco cd mgcl2 supported polypropylene catalyst is presented. the development, the unique method of preparation/production, with emphasis on particle morphology, and the parameters affecting particle size (ps), particle size distribution (psd), and particle shape are discussed in detail. the outstanding performance of the catalyst, tailoredmade for the amoco-chisso...
