در تحقیق اخیر موضوع تغییرات در فرایند ریسندگی الیاف کوتاه مورد بررسی قرار گرفته است .یکی از مسایل مهم در خطوط ریسندگی تنظیم فلصله ،فشار غلتک ها و مقدار کشش در ناحیه کشش عقب break draft ونسبت آن در کشش اصلی main draft است در این تحقیق کشش نواحی فلایر 16 حالتو رینگ در 7 حالت تغییر داده شده است و با استفاده از آنالیز واریانس یک طرفه وچند طرفه بهترین وضعیت مورد بررسی قرار گرفت که فاصله غلتک ها بیشت...
The effects of three levels of soil moisture content (8-10, 10-12 and 12-14% d.b.) and three levels of plowing depth (15, 20 and 25 cm) on draft, specific draft and drawbar power requirement of a 7-shank chisel plow in a clay loam soil were investigated. The experimental design was a randomized complete block design with a 3×4 factorial. The effect of plowing depth on all of the parameters ment...
هدف: کشت سلول های اسپرماتوگونی و تولید سلول های پر توان embryonic stem cells (es like cells) که دارای قابلیت بازسازی و تولید هرسه نوع لایه زایای جنینی می باشند، این سلول ها را به عنوان منبع کافی و جدیدی برای سلول درمانی و ترمیم در بیماریها از جمله بیماریهای نورودژنراتیو پیشنهاد می دهد. در تحقیق حاضر تمایز سلول های اسپرماتوگونی موش به سلول های شبه الیگودندروسیت و نقش آنها درمیلین سازی پس از پیون...
drafts of major primary tillage implements were measured in a clay loam soil using a tension loadcell. implements consisted of a moldboard, a disk and a chisel plow each equipped with one tillage unit. a photoelectric speed sensor was used for actual forward speed measurements. during the study, the effects of forward speed and tillage depth on draft requirements were investigated. a general re...
Objectives Mental health acts have been developed in different countries to protect human and civil rights of people with psychiatric disorders. In Iran, although there are some scattered laws within the existing body of laws, there is no separate mental health act. The aim of the present project was to prepare a draft pertaining to the mental health act in the country. Methods The draft of th...
