A new assay for rheumatoid factor.

This solid-phase immunoassay for detection of rheumatoid factor involves a specially prepared indium surface that renders protein layers visible and therefore does not require tagged protein. Using appropriate discriminatory values, we found agreement with results of a standard latex-fixation test in controls and patients with rheumatoid arthritis. About half of the patients with rheumatoid art...

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 ...

New roles for connexons.

Connexons or gap junction hemichannels are large, nonselective ion channels that reside in the nonjunctional plasma membrane before their assembly into gap junction channels. Increasing evidence suggests that these channels can open under certain conditions and may participate in a number of cellular processes, including the release of small metabolites such as ATP and NAD(+), which are involve...

A New Piecewise EOS for Compressibility Factor Prediction Based on the M-factor Theory

In this study for the first time a new description of compressibility factor is rendered based on the virial expansion. The compressibility factor as a function of M-factor is qualitatively and quantitatively expressed. At first, we present how may the third, fourth and higher order virial coefficients be logically ignored in order to simplify the virial equation. The results show, wh...
