determination of some physical and mechanical properties red bean

چکیده: در این تحقیق، برخی خواص فیزیکی و مکانیکی لوبیا قرمز به-صورت تابعی از محتوی رطوبت بررسی شد. نتایج نشان داد که رطوبت بر خواص فیزیکی لوبیا قرمز شامل طول، عرض، ضخامت، قطر متوسط هندسی، قطر متوسط حسابی، سطح تصویر شده، حجم، چگالی توده، تخلخل، وزن هزار دانه و زاویه ی استقرار استاتیکی در سطح احتمال 1 درصد اثر معنی داری دارد. به طوری که با افزایش رطوبت از 54/7 به 12 درصد بر پایه خشک طول، عرض، ضخام...

study the effects of low level laser diode on no production and healing of diabetic and cortisone acetate and normal wounded sd rats

nitric oxide (no) is a small molecule synthesized by most of mammalian cells with diverse biological activities including vasodilatation, host defense and wound healing. impaired wound healing is a common occurrence among diabetics and patients receiving glucocorticoid therapy. on the other hand the application of laser in biomedical area have been increased. thus, the current studies were desi...

Repair in traumatic ascending aortic rupture and valve insufficiency.

An 18-year-old patient who had chronic traumatic ascending aortic lesion and valve insufficiency, with severe LV dysfunction, was treated by repair of the aortic wall without prosthesis and of the aortic valve by a gluteraldehyde-treated autologous pericardial patch. The patient had an uneventful recovery and minimal residual aortic regurgitation at one-month echocardiographic follow-up. Conser...
