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...
A centrifugal method has been modified and applied to the assessment of water retention value (WRV) in cellulosic materials. Microcrystalline cellulose (MCC), small particles/fibrils isolated from MCC using highpressure homogenizer, and pulp fibers saturated in water were centrifuged at different speeds and times with filter paper and/or a membrane acting as the filter in the WRV measurement se...
A set of instruments and specialized equipment is necessary to equip a laboratory to work with DNA. Reducing the barrier to entry for DNA manipulation should enable and encourage new labs to enter the field. We present three examples of open source/DIY technology with significantly reduced costs relative to commercial equipment. This includes a gel scanner, a horizontal PAGE gel mold, and a hom...
Analysis of Env RNA expression in lung and airways Total RNA was isolated from lung, from trachea and from epithelial tissue scraped from the inside of the nose, by using a Polytron tissue homogenizer (Brinkmann) and Trizol RNA isolation reagent (Invitrogen). Samples were treated with DNase and with reverse transcriptase in the presence of a 3 0 Env primer; they were then subjected to 30 cycles...
Microwave heating was used to prepare optically active thiazole-bearing poly(amide-imide)s. Polymerization reactions were carried out in the molten tetrabutylammonium bromide as a green molten salt medium and triphenyl phosphite as the homogenizer. Structural elucidation of the compounds was performed by Fourier transform infrared and NMR spectroscopic data and elemental analysis results. The p...
Development und experimental testing of a new kind of dielectric barrier discharge flow reactors applicable for plasma-assisted chemical vapor deposition as well as surface treatment processes at atmospheric pressure are described. Using a combination of two upstream modules, a gradient mixer and a homogenizer, the reactor is fed by a laminar gas flow with an established concentration gradient ...
this study was conducted to enhance the antimicrobial properties and water absorption of sanitary papers. for this purpose, montmorillonite nano clay with bentonite brand (has a layered structure in which its thickness is nano metric), was processed with homogenizer to achieve a stable colloidal system with nanometer dimensions of particle size. then, different weight levels of raw and homogeni...
