انتخاب نامساعد یکی از مشکلات اساسی در صنعت بیمه است. که ابتدا در سال 1960، توسط روتشیلد واستیگلیتز مورد بحث ومطالعه قرار گرفت ازآن موقع تاکنون بسیاری از پژوهشگران مدل های مختلفی را برای تجزیه و تحلیل تقاضا برای صنعت بیمه عمر که تماما ناشی از عدم قطعیت در این صنعت میباشد انجام داده اند .وهدف از آن پیدا کردن شرایطی است که تحت آن شرایط انتخاب یا کنار گذاشتن یک بیمه گزار به نفع و یا زیان شرکت بیمه ...
15 صفحه اولConductivity and density of chromic acid solutions
The conductivity and density of chromic acid solutions were determined (<*r concentrations up to 10 molar (1,000 g/1 of Cr03 ). The density is practically a linear function of concentration. The conductivity increases to a maximum at about 5 molar and then decreases. CONTENTS Page
متن کاملNew Grocott Stain without Using Chromic Acid
We established a new "ecological" Grocott stain for demonstrating fungi, based upon a 4R principle of refusal, reduction, reuse, and recycle of waste management. Conventional Grocott stain employs environmentally harsh 5% chromic acid for oxidization. Initially, we succeeded in reducing the concentration of chromic acid from 5% to 1% by incubating the solution at 60°C and using five-fold dilute...
متن کاملChromic Acid Oxidation of Lactic Acid Catalysed by Manganese(II)
B ak o re and N a r a in 1 studied the kinetics of the oxidation of a-hydroxy acids by chromium(VI) and found that addition of Mn(II) decreases the rate of oxidation to one half of that in absence of Mn(II), when the hydrogen ion concentration is in the range 0.1 to 0.4 M. They attributed this to the disproportionation of Cr(IV) by Mn(II) ions. K em p and W a t e r s 2 observed Mn(II) catalysis...
متن کاملAn Industrial Dental-Erosion by Chromic Acid: A Case Report
A case of uncommon occupational dental erosion was reported in an individual who had worked in the war industry for twenty years. This occupation involved daily, at least 8 hours, inhalation of chromic acid being used for cleaning of barrel of cannons. The erosion manifested as dental sensitivity with excessive cervical erosion even with pulpal exposure in certain teeth. Moreover, due to the ad...
