Rate constants for cyanate hydrolysis to urea: A Raman study

Kinetics and mechanism of alkaline hydrolysis of urea and sodium cyanate

The variation of k10bs with [alkali] is linear. at [OH-]=5.0 to 1.5 mol dm-3, thereafter a sharp increase in the reaction rate is observed for first step hydrolysis of urea. The second step rate constant (k2obS)is found to be independent of [alkali].Hydrolysis of urea in alkaline medium follows an eleminationaddition mechanism. The reaction does not proceed through the formation and decompositi...

Direct Determination of Cyanate in a Urea Solution and a Urea-Containing Protein Buffer

a study on rate making and required reserves determination in reinsurance market: a simulation

reinsurance is widely recognized as an important instrument in the capital management of an insurance company as well as its risk management tool. this thesis is intended to determine premium rates for different types of reinsurance policies. also, given the fact that the reinsurance coverage of every company depends upon its reserves, so different types of reserves and the method of their calc...

Urea, urease, cyanate, and the sickling of hemoglobin S.

Urea inglucose solutions has been advanced as a chemotherapeutic agent in sickle cell disease because it has been found effective both in reversing and in blocking sickling. It has been suggested recently that this beneficial action of urea may be the result of formation of cyanate from urea and subsequent carbamylation of beta S globin chains in the hemoglobin S molecule. In this paper, we sho...

a new approach to credibility premium for zero-inflated poisson models for panel data

هدف اصلی از این تحقیق به دست آوردن و مقایسه حق بیمه باورمندی در مدل های شمارشی گزارش نشده برای داده های طولی می باشد. در این تحقیق حق بیمه های پبش گویی بر اساس توابع ضرر مربع خطا و نمایی محاسبه شده و با هم مقایسه می شود. تمایل به گرفتن پاداش و جایزه یکی از دلایل مهم برای گزارش ندادن تصادفات می باشد و افراد برای استفاده از تخفیف اغلب از گزارش تصادفات با هزینه پائین خودداری می کنند، در این تحقیق ...
