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...
We show that the associated production pp → W W , and the rare decay pp → W ′ → l̄lW are useful tests of W ′ couplings to fermions at future hadron colliders. For MW ′ ∼ (1− 3) TeV they would allow a clean determination on whether the W ′ couples to V − A or V + A currents. As an illustration a model in which the W ′± couples only to V −A currents is contrasted to the left-right symmetric models...
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...
In this study, PP films were modified with an organic pro-degradant in different concentrations (1, 2 and 3 wt.%), exposed in the first step of degradation to natural ageing for 100 days followed by biodegradation in simulated soil in the respirometric test for 100 days. At the end of the combined degradation process the PP samples were characterized according to their morphological and physica...
OBJECTIVES Multiple sclerosis (MS) patients frequently suffer from headaches and fatigue, and many reports have linked headaches with intracranial and/or extracranial venous obstruction. We therefore designed a study involving MS patients diagnosed with obstructive disease of internal jugular veins (IJVs), with the aim of evaluating the impact of percutaneous transluminal angioplasty (PTA) on h...
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...
this thesis deals with the construction of some function algebras whose corresponding semigroup compactification are universal with respect to some properies of their enveloping semigroups. the special properties are of beigan a left zero, a left simple, a group, an inflation of the right zero, and an inflation of the rectangular band.
