To clarify aging-related changes in the capillary network in skeletal muscle, we morphometrically examined the capillary supply to individual muscle fibers and capillary luminal size in young (3-month-old) and old (19-month-old) male Wistar rats. All morphometric parameters for capillary and muscle fiber were determined in the cross sections of the perfusion-fixed soleus (SOL) and plantaris (PL...

An experiment was carried out to define the optimal rate of palm-press fibres in growing rabbits' diet. In total, 64 weaned rabbits (35 days old) of Beninese breed were divided in 16 groups of 4 rabbits (2 males and 2 females) each. During six weeks, rabbits were fed with 4 complete diets containing 0% (F0, control), 5% (F5), 10% (F10), and 15% (F15) of fibres from a palm oil industry. Results ...

فرایند جوهرزدایی کاغذ باطله به روش شناورسازی یک فناوری غالب جهانی برای حذف جوهر از کاغذ باطله و استفاده مجدد از الیاف است. در این مطالعه جوهرزدایی از مخلوطی از کاغذ باطله مکانیکی و شیمیایی (Mixed Office Waste) ، کاغذ روزنامه چاپ رنگی (Old Newsprint) وکاغذ مجله باطله (Old Magazine) به نسبت 30:30:40 درصد وزنی، به روش شناورسازی انجام شد. عوامل متغیر شامل مصرف پراکسید هیدروژن (H2O2) و هیدروکسید سدی...
