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.

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 objective of this study was to evaluate the phenotypic lactation curve of crossbred dairy cows raised in Phetchaburi and Prachuap Khiri Khan Provinces. Monthly sampling of daily milk yield of 5516 records from 485 first lactating heifers collected by the Biotechnology in Livestock Production Division Department of Livestock Development during the year 1997 to 2003 were used in this study. Monthly sampling of daily milk yield were fitted using Wilmink function (yt=a+bt+cexp-0.05t) to describe the whole and individual curves and estimated lactation parameters (a b and c). All parameters were used to calculate milk yield at day 60 (MY60) 280 (MY280) peak yield (PM) and accumulated 305 days yield (MY305). The results showed that the fixed effects of herd-year-season of calving level of HF blood or genetic provinces and age of calving were significant differences of all traits (P<0.05; a b c MY60 MY280 PM และ MY305). The phenotypic correlations between the considering traits were significant differences (P<0.05). Moreover the study on the nature of lactation curve could describe the lactating abilities and it could represent the others important traits in lactation curve. Therefore these results could guide the farmers to manage their farm and feeding the cattle to be more effective.

The objective of this research was to evaluate the antioxidant and glucosidase inhibitory activities of 9 fresh and dried local vegetables extract from Kong Ra District Phatthalung Province such as Barringtonia acutangula (L.) Gaertn. Archidendron jirinaga Nielsen Scientific name: in process (Neang-rok: local name) Oroxylum indicum (L.) Kurz Ficus semicordata J.E.Smith Ficus oligodon Mig Ficus sp. Ficus obpyramidata King and Ficus fistulosa Reinw. The antioxidant activities were determined by DPPH radical scavenging. Results indicated that dried crude extract of Oroxylum indicum (L.) Kurz exhibited the highest DPPH radical scavenging activity at the final concentration of 5 mg/ml revealed the DPPH activity as 92.25%. Moreover the extracts were studied for their glucosidase inhibitory activities compare with authentic drug Acarbose Results indicated that dried crude extract of Ficus sp. exhibited the highest inhibitory activity revealed the inhibition activity as 85.46%. Thus these local vegetable might be possible new sources of glucosidase inhibition and antioxidants so there are suitable for use as functional food in the future.

This paper is a presentation of the Load-Frequency Control (LFC) of Interconnected Power System by using Fuzzy Logic and Artificial Neural Network (ANN) Controller. The both of controller have been widely applied for handling the system control of Industries and Engineering. Since the Load-Frequency behaviors of power system of uncontrolled and PI- Controller or Fuzzy Logic Controller (FLC) wanted to the stability at first of energize and load in a short time. The control system and controller then be significant for to go forward reform stability of interconnected energize power system a short time. In this research we have the Load-Frequency Controller of Interconnected Power System by using Artificial Neural Network Controller the improved can compared with conventional Fuzzy Logic Controller at power total 47.55 MW and load changing of power plan No.3 is 0.02 p.u. (1.75 MW)
