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...
With the effect of technological advances, use electrical and electronic devices has increased dramatically in recent years. Wireless technologies related applications are mostly preferred for communication these with each other. Thus, people easily exposed to electromagnetic waves daily life. The extensive global raises question their possible biological effects on human health. Also, influenc...
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 ...
asymmetric membranes are widely used in many industrial membrane separation processes. the major advantage of membrane filtration over the conventional process is its ability to remove a wider spectrum of particles without using any chemicals. hollow fiber configuration offer many advantages over flat-sheet or tubular membranes. the spinning process of hollow fiber may look simple, yet it is te...
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...
