Cyanoborane adducts of the Lewis acids B(CN)3, BF(CN)2, and BH(CN)2 with pyridine 4-cyanopyridine have been obtained in high yields. The syntheses were accomplished by oxidation readily available potassium salts cyano(hydrido)borate anions [BH(CN)3]− (MHB), [BFH(CN)2]− (FHB), [BH2(CN)2]− (DHB) bromine presence respective derivative C5H5N or 4-CN-C5H4N as starting material. All six cyanoborane c...
A new fast and reliable reversed-phase high-performance liquid chromatographic method is proposed for quantifying all the major casein fractions during cheese proteolysis as an alternative to more complex methodologies. Excellent separation of caseins, para-κ-casein (ρ-κ-CN), αs1-casein (αs1-CN), αs1-I-casein (αs1-I-CN), αs2-casein (αs2-CN), β-casein (β-CN) was achieved, in terms linearity, rep...
the main goal of this paper is to propose a new practical method for hydrologic soil group estimation in surface runoff process based on geomorphology facieses and slop. the determination of cn based on this method can reduce the time and cost of project. in this research the upstream rivers of glinak watershed have been used as a case study to examine the efficiency of proposed method with a c...
Denote by R(L, L, L) the minimum integer N such that any 3-coloring of the edges of the complete graph on N vertices contains a monochromatic copy of a graph L. Bondy and Erdős conjectured that when L is the cycle Cn on n vertices, R(Cn, Cn, Cn) = 4n − 3 for every odd n > 3. Luczak proved that if n is odd, then R(Cn, Cn, Cn) = 4n + o(n), as n → ∞, and Kohayakawa, Simonovits and Skokan confirmed...
The colorless salts [C5H10NH2][Au (CN)2], [C4H8NH2][Au (CN)2], [Ph2NNH3][Au (CN)2] H2O and [(n-C3H7)4N][Au(CN)2] H2O have been prepared by evaporation of aqueous solutions of potassium dicyanoaurate and the chloride salt of the appropriate cation. Hydrogen bonding between the cations and the cyano groups of the anions facilitates the formation of structures with strong aurophilic interactions b...
Background: Mutations of ELA2, the gene encoding neutrophil elastase (NE) are known to be associated with cyclic neutropenia (CN) and severe congenital neutropenia (SCN). However, high variability of these mutations has been reported. This study was designed to describe the analysis of the ELA2 gene, clinical manifestations and demographic characteristics in patients with CN and SCN. Methods...
با توجه به اینکه اغلب حوضه‌های آبریز فاقد آمار و اطلاعات با کفایت لازم هستند، شبیه سازی بارش- رواناب منطقه شمال نیشابور در سیستم هیدرولوژیک با الگوریتم‌های مدل HEC-HMS پایه ریزی شد. الگوریتم انتخابی در مدل مذکور، روش SCS(CN) می باشد. شماره منحنی حوضه برای شرایط متوسط بر اساس اطلاعات پوشش گیاهی، کاربری اراضی، گروه‌های هیدرولوژیک خاک و جدول SCS محاسبه شد. روندیابی موج سیل نیز در بازه‌های مورد ن...
for any group g, let c(g) denote the set of centralizers of g.we say that a group g has n centralizers (g is a cn-group) if |c(g)| = n.in this note, we prove that every finite cn-group with n ≤ 21 is soluble andthis estimate is sharp. moreover, we prove that every finite cn-group with|g| < 30n+1519 is non-nilpotent soluble. this result gives a partial answer to aconjecture raised by a. ashrafi in ...
