This process produces high yield and high purity CNTs at cost -effective manner. FeCl3 was found to be an efficient FC precursor to decompose methane into CNTs. The effects of different process parameters such as reaction temperature, reaction time and gases flow rate on the morphology of CNTs were investigated. The morphology of the carbon layers deposited on the quartz wall was characterized by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). In addition, energy dispersive X -ray (EDX) was employed to study the quality of the CNT samples, thermogravimetric analysis (TGA) for the yield of CNTs and the graphitization of CNTs’ wall structure was investigated by Raman spectroscopy. OTH-O2 EFFECT OF VARING LEVELS OF N-6: N-3 FATTY ACID RATIO ON PLASMA FATTY ACID COMPOSITION AND PROSTANOID SYNTHESIS IN PREGNANT RATS A.B. Amira , A.B.Z.Zuki, Y.M. Goh and M.M.Norrdin Faculty of Veterinary Medicine, University Putra Malaysia, 43400 Serdang, Selangor, Malaysia E-mail: amirabary@gmail.com The effect of dietary fats with varying levels of n-6: n-3 fatty acid ratio was studied in twenty eight female tow month old Sprague Dawely Rats, were randomly divided into four groups (seven rats per treatment). Treatment diets were rat chow only control diet (con), rat chow containing 0.9 mL soybean oil (SO) + 0.9 mL cod liver oil (CLO) /15 g/ rat the ratio 1:1, rat chow added with CLO + 1.5 mL SO + 0 .3 mL /15 g/rat the ratio 6:1 and rat chow added with 1.74 mL SO + 0.06 mL CLO / 15 g/rat the ratio 30:1, feeds of 15g/day were given and wate...
