A Novel Approach for Direct Preparation of Hydroxyapatite Nanoparticles from natural source using Microwave
Hydroxyapatite (HA) is one of the most common biocompatible ceramic with wide usages in various aspects of medicine due to the resemblance to the mineral bone tissue. The particle size of HA has a key roll in determination of the reaction rate at the interface of natural bones/artificial. Accordingly, this paper tries to propose a novel approach for the preparation of HA nanoparticles from natu...

در این پژوهش به بررسی اثر افزایش ترافیک بر روی تعداد تصادفات پرداخته شده است. به این منظور 30 تقاطع در شهر تهران بطور تصادفی انتخاب گردید و تعداد تصادفات ماهیانه در این تقاطعات در طول سالهای 89-90 از سازمان کنترل ترافیک شهر تهران استخراج گردید و با استفاده از مدل داده های تابلویی و نرم افزار eviews مدل خطی و درجه دوم تخمین زده شد و در نهایت این نتیجه حاصل شد که تقاطعات پر ترافیک تر تعداد تصادفا...
15 صفحه اولSource of nuclear calcium signals.
Transient increases of Ca2+ concentration in the nucleus regulate gene expression and other nuclear processes. We investigated whether nuclear Ca2+ signals could be regulated independently of the cytoplasm or were controlled by cytoplasmic Ca2+ signals. A fluorescent Ca2+ indicator that is targeted to the nucleus was synthesized by coupling a nuclear localization peptide to Calcium Green dextra...
متن کاملHydration of the calcium dication: direct evidence for second shell formation from infrared spectroscopy.
Infrared laser action spectroscopy in a Fourier-transform ion cyclotron resonance mass spectrometer is used in conjunction with ab initio calculations to investigate doubly charged, hydrated clusters of calcium formed by electrospray ionization. Six water molecules coordinate directly to the calcium dication, whereas the seventh water molecule is incorporated into a second solvation shell. Spec...
