Fine Comminution of Pine Bark: How Does Mechanical Loading Influence Particles Properties and Milling Efficiency?

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...

Pheromone response in pine bark beetles: influence of host volatiles.

How does static stretching influence the tendons mechanical response?

OBJECTIVE Analyze in vitro the mechanical response of bovine calcaneus tendons subjected to static stretching in three different intervals (15, 30, 45 s). METHODS Six groups of bovine calcaneus tendons (n=10) were formed according to the static stretching protocol: three different intervals (15, 30, 45 s) and initial stretching percentage (2.5% and 3.5%). The control group (n=10) did not perf...

Study of milling effect on particle size and mechanical properties of WC-Co composite

The effect of milling on the particle size and mechanical properties Tungsten Carbide - Cobalt composite were investigated. First, raw materials ratios by mechanical milling for 4 hours at 300 rpm were mixed. The powder in the optimum temperature 1350°C at a rate of temperature rise 50°C / min and shelf life of 4 minutes and the pressure MPa 30 were sintered in SPS. The results indicated nearly...
