Arachis glabata is new variety forage which tolerates drought and provide high protein.This kind of plant is suitable as dairy cow diet. The research was divided into 2 experiments Experiment 1 was conducted to study on nutritive value of Arachis glabata.The experimental design was Randomized Completely Block Design (RCBD) experiment with three treatments. Each treatment consisted of three blocks (three crops) and followed different three variety of Arachis glabata as Cv. Florigraze Cv. Arbook and Cv. Ecotart. Results showed that three variety of Arachis glabata were 28.26-30.75 % of dry matter (P>0.05). In addition Arachis glabata Cv. Arbook was grater 19.78 % of protein than other group of Arachis glabata (P<0.01). Furthermore Arachis glabata Cv. Florigraze was grater 17.63 of hemicelluloses and 3830.00 kcal/kg of gross energy significant different among other group of Arachis glabata (P<0.05). Experiment 2 was conducted to study on ruminal degradability of Arachis glabata using In situ technique in dairy cattle. The experimental design was Randomized Completely Block Design (RCBD) experiment with three treatments. Each treatment consisted of three blocks (three ruminally fistulated dairy cattle) and followed different three variety of Arachis glabata as Cv. Florigraze Cv. Arbook and Cv. Ecotart. Results showed that Arachis glabata Cv. Florigraze and Arachis glabata Cv. Arbook was grater dry matter organic matter and protein degradability at 0-4 hour and 24-28 hour than Arachis glabata Cv Ecotart (P<0.05). In addition kinetic of degradation (a b c and p) of dry matter organic matter and protein were not significant different (P>0.05) among three variety of Arachis glabata.

The objective of this research is to investigate microstructure and mechanical properties of brass welded by diffusion welding process. The diffusion welding (DW) of brass welded over lap joints bonding parameters were pressure at temperature 500 650 and 800 0C contact pressure of 12 MPa and holding time for 60 minutes respectively. The microstructure mechanical properties and behaviour during bonding were investigated. The results show that in weld zone (Bond Line) diffusion of atom the brass significantly. The mechanical properties after diffusion welding process increased higher temperature

The study of factors influencing to the inappropriate behaviors of SCUBA divers in coral reef areas was done. The study performed by Quota sampling technique which the data was collected from 279 divers. The frequency of inappropriate behaviors of divers was recorded for in 10 minutes each. The results show that the average contacts damage and interference to aquatic organisms made by individual divers were 2.20 0.22 0.02 ? 0.01 and 1.70 0.20 respectively. No significant difference of factors of contact and damage made by divers but there was significant difference between nationality (t = 5.24; df = 277; p < 0.001) and pointer possession (t = 2.59; df = 277; p < 0.01) with the number of times divers made interference the aquatic organisms. This study results can be used to propose the guidelines and management strategies for conservative and sustainable of SCUBA diving in the coral reef.

The purposes of the research were; 1) to study the relative rotation of AC-generator 2) to study the angular velocities of magnetic coil and permanent magnetic influence generating voltage of AC-generator and 3) to construct predictive equations of generating voltage of AC-generator. By the 12-V 6-pole alternator of motorcycle Pearson’s correlation and regression analysis the findings revealed that: 1) At the lowest relative angular velocity of 376 rpm the generating voltage is 3.28 V. While the highest relative angular velocity of 2280 rpm the generating voltage is 22.98 V. 2) The angular velocity of permanent magnetic has great influences on generating voltage than the angular velocities of magnetic coil at the .01 level of significant and 3) function as below : Generating voltage = 0.806 (Velocity of permanent magnetic) + 0.634 (Velocity of magnetic coil)
