Human fibrinogen chromatographed on DEAE-cellulose resolves into two components containing 85% (peak 1 ) and 15% (peak 2) of the total fibrinogen. Peak 1 and peak 2 differ only in the composition of their ‘y chains, with peak 1 containing only one type of “y chain and peak 2 containing equal amounts of ‘y chain and a second chain, called ‘y’. In an effort to explain the difference in the amount...

ABSTRACT: Reproductive effi ciency is of economic importance in commercial beef cattle production, since failure to achieve pregnancy reduces the number of calves marketed. Identifi cation of genetic markers with predictive merit for reproductive success would facilitate early selection of females and avoid ineffi ciencies associated with sub-fertile cows. To identify regions of the genome harb...

Yersiniosis is a food-borne illness that has become more prevalent in recent years due to human transmission via the fecal-oral route and prevalence in farm animals. Yersiniosis is primarily caused by Yersinia enterocolitica and less frequently by Yersinia pseudotuberculosis. Infection is usually characterized by a self-limiting acute infection beginning in the intestine and spreading to the me...

ویژگی های گراف مقسوم علیه صفر یک حلقه جابجایی و گونای آن را مورد بررسی قرار می دهیم. بویژه، تمام حلقه های جابجایی متناهی و یکدار که گراف مقسوم علیه صفر آنها دارای گونای یک است را مشخص کرده و رده بندی می نماییم. همچنین نشان می دهیم که برای یک عدد صحیح مثبت ثابت g، تعداد متناهی کلاس هم ارزی از حلقه هایی که گراف مقسوم علیه صفر آنها دارای گونای g است، وجود دارد. برای این منظور مقالات زیر را مورد م...

In this paper, a new class of multifunctions, called generalized $alpha(mu_{X},mu_{Y})$-continuous multifunctions, has been dened and studied. Some characterizations and several properties concerning generalized $alpha(mu_{X},mu_{Y})$-continuous multifunctions are obtained. The relationships between generalized $alpha(mu_{X},mu_{Y})$-continuous multifunctions and some known concepts are also di...

As we will later see, a crucial role in model building is played by symmetries. You are already familiar with symmetries and with some of their consequences. For example, Nature seems to have the symmetry of the Lorentz group which implies conservation of energy, momentum and angular momentum. In order to understand the interplay between symmetries and interactions, we need a mathematical tool ...

In this research, zeolite Na-Y was synthesized from Kaolin without an organic template under the non-hydrothermal condition to adsorb sulfur compound. Model fuel desulfurization was optimized by employing the Box-Behnken experimental design with 2 center points, the three parameters, and one response value. The objective was to find how sorption capacity is related to alkali fusion temperat...

بید گوجه‌فرنگی، Tuta absoluta (Meyrick) یکی از آفات مهم گوجه‌فرنگی Solanum lycopersicum L. است. در این تحقیق ویژگی‌های چرخۀ زیستی بید گوجه‌فرنگی روی پنج رقم گوجه‌فرنگی به نام‌های Super Strain B، Super Chief، Early Urbana Y111، Mobil و Early Urbana Y در شرایط گلخانه‌ای مطالعه شد. نتایج نشان داد که رشدونمو لاروی روی رقم‌های Mobil و Early Urbana Y در مقایسه با دیگر رقم‌های تحت مطالعه کندتر بود. تع...
