Book Review: Inside Prime Time. By Todd Gitlin. New York: Pantheon Books, 1983. Pp. viii +372. $16. 95. This review is available at ScholarlyCommons: http://repository.upenn.edu/asc_papers/157
هدف از این تحقیق، کاهش جذب آب پلی آمید-6 بدون تنزل خواص مکانیکی و فرآیند پذیری آن، توسط مخلوط کردن آن با پلی پروپیلن، سازگارکننده pp-g-mah و نانو ذرات کربنات کلسیم می باشد. پلی-پروپیلن به خاطر خاصیت آب گریزی و شرایط فرآیندی و آسان آن و نانو ذرات کربنات کلسیم با توجه به ساختار شبه کروی، خاصیت جوانه زنی کریستالی و اثر تقویت کنندگی آن انتخاب گردیدند. برای بهبود اثر متقابل پلیمرهای فاز زمینه و همچن...
کامپوزیت¬های پلیمری هادی بر مبنای زمینه¬ی پلیمری عایق و پرکننده¬ی هادی الکتریسیته، همچون دوده، خصوصیات جالبی در تغییر خواص الکتریکی و مکانیکی از خود نشان می¬دهند. در این مطالعه خواص الکتریکی و شکل¬شناسی آمیخته پلی اتیلن ترفتالات / پلی¬پروپیلن، (20/80) pp/pet ،پرشده با ذرات دوده هادی و معمولی مورد بررسی قرار می¬گیرد. کامپوزیت حاوی دوده هادی در مخلوط¬¬کن داخلی تهیه شد. بدین ترتیب که ذرات دوده ا...
OBJECTIVES To describe changes among smokers in use of various types of tobacco products, reported prices paid and cigarette consumption following the standardisation of tobacco packaging in Australia. METHODS National cross-sectional telephone surveys of adult smokers were conducted from April 2012 (6 months before transition to plain packaging (PP)) to March 2014 (15 months afterwards). Mul...
In sympathetic neurons, C6-ceramide, as well as endogenous ceramides, blocks apoptosis elicited by NGF (nerve growth factor) deprivation. The mechanism(s) involved in ceramide-induced neuronal survival are poorly understood. Few direct targets for the diverse cellular effects of ceramide have been identified. Amongst those proposed is PP-1c, the catalytic subunit of serine/threonine PP-1 (prote...

nanocomposites based on polyamide 6/polypropylene )pa6/pp 67/33) blend containing 2.5 to 10 phr of nano-caco3 and 5 phr of maleated polypropylene )pp-g-mah) as compatibilizer were prepared by melt compounding followed by injection molding. the mechanical properties, water absorption, as well as shrinkage behavior were characterized and the morphology was studied using scanning electron micros...
rain, m.u. i aie univcrsny, ruuaueipma and London : W. B. Saunders Co., Ltd. 1923. Pp. 258. Price, 12s. 6d. net. This small volume is an essay for the practising physician and health worker rather than a text-book for the public health student. As it deals with American statistical data which are differently recorded from those of England, the book is not adapted for teaching in India or Englan...
Two peach genes homologous to the Arabidopsis ethylene receptor genes ETR1 and ERS1, named Pp-ETR1 and Pp-ERS1 respectively, have been isolated and characterized. Pp-ETR1 and Pp-ERS1 are conserved in terms of exon numbers and intron positions, although the first and fifth introns of Pp-ETR1 have an unusual length. In addition, two putative polyadenylation sites, that may cause an incomplete spl...
