The calculation of a reliable temperature dependent dolomite solubility product constant (Ksp?dol) has been the subject much research over last 70 years. This study evaluates log10(aCa2+/aMg2+) values using PHREEQC (Pitzer approach) for screened subset (n = 11,480) formation waters in U.S. Geological Survey National Produced Wate...
In this work we reported about the use of an electrolyte for lithium-ion batteries (LIBs) based on mixtures 1,3-dioxolane (DOL) and 1,2,2-tetraethoxyethane (TEG). We showed that 1 M LIFSI in TEG : DOL (2 3) displays good transport properties high thermal stability. Graphite lithium-iron phosphate (LFP) electrodes used combination with display capacity, efficiency, high-capacity retention at hig...
Data mapping is the essence of being human. This report follows the process of data mapping; the transmission of a structured utterance from one domain to another. It starts with signals in the world and moves through experience and engagement with the world through those signals. The paper develops descriptions of the materials and mechanisms of data mapping. The descriptions are aids and conv...

OBJECTIVES The aim of the present study was to examine the growth and tolerance of infants fed infant formulas with a caloric density closer to human milk (HM) supplemented with human milk oligosaccharides (HMOs) and to study uptake of the HMOs. METHODS A prospective, randomized, controlled, growth and tolerance study was conducted in healthy, singleton infants (birth weight ≥2490 g), who wer...
The biosynthesis of asparagine-linked glycans occurs in an evolutionarily conserved manner with the assembly of the unique lipid-linked oligosaccharide precursor Glc3Man9GlcNAc2-PP-Dol at the ER (endoplasmic reticulum). In the present study we characterize Alg11 from yeast as a mannosyltransferase catalysing the sequential transfer of two alpha1,2-linked mannose residues from GDP-mannose to Man...
the purpose of this paper is a study on the effect of cash flows on the gap between actual and optimal financial leverage ratio companies listed in tehran stock exchange. in this regard, we try to help with advanced econometric techniques such as partial adjustment model on panel data and generalized method of moments to achieve a reasonable estimate of the impacts.in this paper, were analyzed ...
