Molecular Weight Distribution of Polyoxymethylene Produced by Scission Reaction

CONTROL OF MOLECULAR WEIGHT DISTRIBUTION OF THE BIOPOLYMER PULLULAN PRODUCED BY THE FUNGUS Aureobasidium pullulans

High Molecular Weight Derivatives of Human Fibrinogen Produced by Plasmin

Two high molecular weight derivatives of fibrinogen (Fragments X and Y) produced by plasmin digestion have been identified by comparative analyses of the digests in agar, agarose, and acrylamide electrophoresis, immunoelectrophoresis, Sephadex G-ZOO gel filtration, and analytical ultracentrifugation. These fragments were purified by salt precipitation and Sephadex G-200 gel fltration and their ...

Conagenin, a low molecular weight immunomodulator produced by Streptomyces roseosporus.

effect on T lymphocytes. Fermentations for the production of conagenin were done as follows. S. roseosporus was cultured in 500-ml Erlenmeyer flasks containing 1 10 ml of the autoclaved seed medium consisting of galactose 2.0%, dextrin 2.0%, soy peptone 1.0%, corn steep liquor 0.5%, (NH4)2SO4 0.2%, CaCO3 0.2% and one drop of silicone. The seed medium was adjusted to pH 7.4 with 1 n HC1 and was ...

Rheological Method for Determining Molecular Weight and Molecular Weight Distribution

modeling loss data by phase-type distribution

بیمه گران همیشه بابت خسارات بیمه نامه های تحت پوشش خود نگران بوده و روش هایی را جستجو می کنند که بتوانند داده های خسارات گذشته را با هدف اتخاذ یک تصمیم بهینه مدل بندی نمایند. در این پژوهش توزیع های فیزتایپ در مدل بندی داده های خسارات معرفی شده که شامل استنباط آماری مربوطه و استفاده از الگوریتم em در برآورد پارامترهای توزیع است. در پایان امکان استفاده از این توزیع در مدل بندی داده های گروه بندی ...
