This paper presents a study of low-frequency oscillations in compensated electric power systems with Flexible AC Transmission System of the power system frequency using PSAT Tool box To assist in the analysis of the stability of the system When the power transients in power systems is simulated By using standard IEEE 14 bus system as a case study. The Equipment that used to control the swing frequency of the is a flexible electrical power control devices or FACTS are two kinds of serial and parallel. The analysis showed that two models are compared with the time (Time Domain) and see the effect of the Eigen (Eigen Value) of the simulation results show work to see that controls are electrical flexible compensation. of low frequency oscillations in power systems in acceptable coordinates

Physic Nut (Jatropha curcas L.) was a narrow genetic based plant resulting in low productivity. Colchicine application was a mutation technique that could induce genetic variability for plant improvement. In this study the 24 hour soaked physic nut seeds and the 3 – day physic nut seedlings were treated with 0 0.05 0.15 and 0.20% of colchicine for 48 hours and there were soaked for 24 hours to induce polyploidy. The results showed that the survival rates were 67.15 and 93.93 % at the 0.05% of colchicine. DNA content in the survived seedlings was detected by flow cytometry. The number of tetraploid and mixoploid were increased in the 3-day seedlings treated with 0.05% of colchicine. The morphology characteristics at the first flowering stage were follows; the diploid had average height branch numbers spikelets per head ratio of male and female flowes leaf size (W x L) and stomata size (W x H) were 249.50 cm. 15.7 214.7 24.8 :1 14.8 x 13.2 cms and 7.88 x 50.25 micrometers respectively while the mutant had the average of 180.6 - 21.54 cm. 9.8 - 13.0 37.9 - 17.53 19.3 : 1 42.8 : 1 17.0 - 14.4 cms and 61.0 - 70.5 x 103.33 - 116.1 micrometers respectively. so The mutant had better characteristics but their fruits could not mature.

The objective of this research is to produce the T-Bar. The mixed Gule Phenol-cyanate to made ceiling Plate-Bar plate from the agriculture process’s waste. The researcher brought physic nut plant to produce T- BAR plate for interior building. It was tested based on Thailand industrial standard (TIS 876-2547) for determination of moisture content density absorption and expansion when soak in water as well a cohesion and perpendicular surface tension flexural resistance and modulus of elasticity . at The results show that suitable size material should not thicker than 2 centimeters. The experiment of ratio between physic nut plant and phenol cyanide resin at 90:10 and 92:8. It was found that suitable proportion of physic nut pant and phenol cyanide resin was 92:8. The temperature used for compression was 120o C. The appropriate density prior to the compression plate was 0.80 g/cm.3 The average moisture content of materials before compression was 8.88%. The suitable compression was 151 lb/in?. The moisture content of the product was 7.64% The density was 0.818 g/cm.3 The expansion value after soaking in water for 2 hours was 8.02% and water absorption was 14.22%. Inner bond was 0.55 MPa. Flexibility was 22.44 MPa. and mordulus was 2112MPa.The result of testing complied with the Thailand Industrial Standard (TIS 876-2547).It was concluded that physic nut plant can be used as raw material to make T- Bar plate for interior building

These dissertation is discussed development of Automatic Provision Paper Machine. By apply suction roller in the paper provision paper of size A4 to as a set and suture package control by microcontroller AVR MEGA 1280. Which the machine has 8 layer each layer has 50 sheets use the time for provision 40 second per minute that 1 set has 8 sheets. From the results of the equipment. It have some problem form suction rollers system. May be caused equipment in each is different an size roller or stiffness of spring and errors. Sensor is detect camshaft at moving through the disturbance of the light surround area with too much ability to detect lower. Which the repair and amend it

The fault in a power distribution system disturbs the power dispatch under normal conditions therefore decreases the quality of the electric power. The single line to ground fault is an asymmetric fault that may have a high percentage chance to happen. The kind of fault changes power and voltage dramatically. The size of the phase voltage decreases which affect the economic damage of the system. This paper presents an analysis of grounding systems to reduce voltage drop in a power distribution system by using the technical analysis system in case of one phase to ground fault. The objective is to minimize voltage drop for users using the simulation with single line to ground fault in distribution system voltage level at 22 kV PEA’s test system. The simulation utilizes the EMTDC-PSCAD program. The results show that the grounding method can reduce the voltage drop and reduce the damage of the economic system
