در این تحقیق سیمان کامپوزیتی کلسیم فسفاتی جدیدی مورد ارزیابی قرار گرفت. در بخش پودری سیمان، از براشیت و کلسیم فسفات بیولوژیکی که طی فرآیند آنیل از استخوان ماهی تن تهیه شد، استفاده گردید. بخش مایع سیمان شامل کیتوسان حل شده در اسید استیک 2 درصد بود. برای تهیه سیمان کامپوزیتی از پودرهای بیولوژیک تهیه شده در c?600 و c?900 استفاده شد. پودر تهیه شده از استخوان ماهی و نمونه های کامپوزیت سیمان جدید مشخ...
chapters 1 and 2 establish the basic theory of amenability of topological groups and amenability of banach algebras. also we prove that. if g is a topological group, then r (wluc (g)) (resp. r (luc (g))) if and only if there exists a mean m on wluc (g) (resp. luc (g)) such that for every wluc (g) (resp. every luc (g)) and every element d of a dense subset d od g, m (r)m (f) holds. chapter 3 inv...
There is a general agreement between researchers that particle size of poultry feed should be between the size ranges of 600-900 µm. This study investigated the particle size of poultry feed produced in the Dormaa Municipality of Ghana. A survey was conducted on various feed mills which were made up of nine on-farm mills and five community-based commercial mills. Feed samples were collected fro...
Berbagai modifikasi mesin dilakukan dengan tujuan meningkatkan performa kendaraan bermotor. Peningkatan yang paling banyak cara memperbaiki tingkat efisiensi volumetrik campuran bahan bakar dan udara masuk ke dalam silinder motor. Dengan terhalangnya aliran dari arah depan kendaraan, maka perlu dikaji seberapa besar pengaruh sudut intake manifold mengalirkan motor terhadap daya, torsi, kecepeta...
Background and Objective Multi-walled Carbon Nano Tubes (MWCNTs) as an important element of nanosciences have a remarkable absorption in the region of NIR window (650-900 nm) which can overcome the limitations of deep treatment in photothermal therapy. To disperse MWCNTs in water, it is proposed to attach carboxylated functional group (-COOH) to MWCNTs in order to increase dispersivity in water...
Performance of symmetric-architecture metal-supported solid oxide fuel cells was improved significantly by optimizing the catalyst infiltration process and metal support structure. Optimization component structure processing parameters performed during tape-casting fabrication button cells. Mass transport oxygen in identified as a major limitation. To overcome this limitation, pore former loadi...
La alfarería Aguada Portezuelo del Noroeste Argentino (ca. 600-900 d.C.) presenta una gran complejidad en sus intervenciones plásticas siendo su marcada policromía uno de aspectos más llamativos. utilización multiplicidad pigmentos por parte los alfareros antiguos para obtener diferentes colores hace necesario un mejor entendimiento las cadenas operativas involucradas el manejo estos. En este t...
in this thesis, barium ferrite nano particles were prepared by sol-gel method. their structural and magnetic properties of samples have been investigated using thermo gravimetric analysis (tg-dta), x-ray powder diffractometer (xrd), fourier transform infrared (ftir), scanning electron microscopy (sem), field emission scanning electron microscopy (fesem), ac susceptometer, vibrating sample magne...
