Bakırın yüksek elektriksel iletkenlik ve termal gibi mükemmel özelliklerine rağmen mekanik özelliklerinin zayıf olması, geliştirilmesi gerçeğini ortaya koymaktadır. Bu çalışmada toz metalürjisi ile üretilen Cu-Cr-B4C-CNF hibrit kompozitlerin özelliklerini iyileştirmek amacıyla aşınma özellikleri deneysel olarak araştırılmıştır. Kompozitlerin performanslarını belirlemek pin-on-disk metodu kullan...

A new series of 5-(indole-2-yl)-3-substituted 1,2,4-oxadiazoles were synthesized and evaluated for their anticancer activities. Structures of the compounds were confirmed by spectroscopic methods. Structural modifications were done to improve the antiproliferative activity of compound 1. The results indicated that a benzyloxyl substituent on the C-4 position was better than a methyl substituent...

ment, together with a summary of the remarkable chemical reactivity of this unit. Ion exchange chromatography (Dowex 50Wx8) of the acid hydrolysate (10N hydrochloric acid, reflux for 24 hours) of viomycin afforded two basic amino acids, viomycidine and a small amount of a compound which we have termed viocidic acid. Viomycidine was characterised as its crystalline monohydrochloride m. p. 200~20...

Methods Twenty-four New Zealand white rabbits were surgically instrumented and underwent a bout of damaging eccentric exercise to the tibialis anterior muscle. Rabbits were randomly assigned to a protocol with massage frequency of 0.25 or 0.50Hz at a compressive force of 5 or 10N for 15 or 30 minutes. The contralateral limb served as the exercised, non-massaged control. A torque-angle relations...

Objectives/Goals The purpose of this project was to study the growth of the bacteria Escherichia coli DH5a under a variety of different pH and temperature, in order to discover and approximate the optimal value at which the cell was able to increase in size and divide the quickest. Methods/Materials Material used for this experiment included Eschericha coli DH5a, flasks, cuvettes, test tubes, a...
