Physical vacuum properties and internal space dimension

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...

Effect of acidity and physical properties of nanozeolite catalyst on hydrocracking of vacuum gas oil

In this study, beta nanozeolite, ultra-stable Y zeolite (USY) and amorphous silica-alumina (ASA) were synthesized. These compounds were used as the support of hydrocracking catalyst. Ni-Mo/beta zeolite-ASA and Ni-Mo/USY zeolite-ASA catalysts were prepared by the impregnation method. The samples were characterized with X-Ray diffraction (XRD), field emission-scanning electron microscopy (FE-SEM)...

Vacuum properties of nonsymmetric gravity in de Sitter space

Vacuum properties of nonsymmetric gravity in de Sitter space Tomas Janssen and Tomislav Prokopec Institute for Theoretical Physics (ITP) & Spinoza Institute, Utrecht University, Leuvenlaan 4, Postbus 80.195, 3508 TD Utrecht, The Netherlands Abstract We consider quantum effects of a massive antisymmetric tensor field on the dynamics of de Sitter spacetime. Our starting point is the most general,...

single vacuum bagging and autoclave curing system influence on physical and mechanical properties of phenolic composites

industrial production of thermoset composite components involves the application of a vacuum bagging and autoclave pressure to minimize void percentage, usually to less than 5%. phenolic resin systems generate water as a reaction byproduct via condensation reactions during curing at elevated temperatures. in this paper, vacuum bagging and simple manufactured autoclave curing systems are used fo...
