The present work aimed to evaluate capability of a new molecular structure to stabilize polyethylene against thermal oxidation. Hence, effects of 3,3-bis(4-hydroxy-2-methyl-5-propan-2-ylphenyl)-2-benzofuran-1-one (thymolphthalein) on thermo-oxidative stability of high density polyethylene (HDPE) in both solid and melt states were investigated and compared with those of SONGNOX 1010, a comme...
In order to investigate the effects of municipal solid waste enriched with mineral fertilizers on some soil physical properties and lead (Pb) and chromium (Cr) concentration in plant organs of spinach, a field experiment was carried out in a factorial arrangement based on the randomized complete block design with three replications in 2008. The main plot included four levels of fertilizer, cont...
چکیده به منظور بررسی اثر تنوع گیاهی و نوع منبع تغذیه ای بر تنوع و تراکم علفهای هرز و حشرات، کارایی مصرف نهاده ها ( نور، آب، عناصر غذایی) و عملکرد و خصوصیات کیفی چند گونه زراعی، آزمایشی به صورت کرتهای خردشده بر پایه طرح بلوکهای کامل تصادفی با سه تکرار در دو سال زراعی 1385-1384 و 1386-1385 در مزرعه تحقیقاتی دانشکده کشاورزی دانشگاه فردوسی مشهد به اجرا درآمد. تیمارهای مورد بررسی دو منبع کود دامی و...
A Cocrystallization is an attractive molecular engineering approach for realizing improved energetic materials (explosives, propellants, and pyrotechnics). When two or more neutral species are combined to form a new structure, cocrystalline materials are created with distinct solid-state properties. As the performance criteria of energetic materials (explosive power, thermal stability, and phys...
Multinuclear three-dimensional solid-state MRI of bone, tooth, and synthetic calcium phosphates is demonstrated in vitro and in vivo with a projection reconstruction technique based on acquisition of free induction decays in the presence of fixed amplitude magnetic field gradients. Phosphorus-31 solid-state MRI provides direct images of the calcium phosphate constituents of bone substance and i...
The B16 melanoma-derived low lung-colonizing variant B16-F1 and the high lung-colonizing variant B16-F10 retained their differential lung-colonizing abilities throughout at least 35 serial s.c. transplant generations. The majority of the cells originating from solid B16-F1 tumors had a higher density than did cells originating from solid B16-F10 tumors. Cell suspensions of unselected solid B16 ...
background : angiogenesis is essential for the growth, invasion and metastasis of solid tumors. research on related factors such as microvessel density can be helpful in predicting a tumor's behavior. cd105 has been introduced as a marker of angiogenesis which stains vessels that are in the proliferating stage. there are some controversies about the relation of microvessel density and clinicopa...
