A research was aimed to investigate appropriate procedures of cabinet drying of flour made from Toddy palm at 60 65 and 70 degree Celsius and employed it as an ingredient in 3 Thai traditional desserts - Kanom-Chun Kanom Num-dok-mai and Kanom Puy-fai respectively. The investigation emphasized on these effects on color and odor of the products. Palm flours at the level of 0% 10% 20% and 30% was added then physical and chemical properties consumer’s acceptance were investigated and their shelf-life of the products packed in polyvinyl chloride and double layer of polyvinyl chloride and polyethylene at room temperature was inspected every day. Drying temperature of 60 ?C and 10% flour addition in the formulation found to be the optimal condition and also produces best quality of the products accepted by consumers as in such conditions overall score of acceptance was statistically significantly highest ( P>0.05) with 7.73 7.95 and 7.62 average scores for Chun Kanom Num-dok-mai and Kanom Puy-fai consecutively. Proximate analysis of these products in terms of moisture ash fat fiber protein and carbohydrate revealed that they were statistically different ( P>0.05). When 100 consumers were asked to taste and rank their acceptances Kanom Puy-fai Kanom Num-dok-mai and Kanom Puy-fai was acceptable by 66 28 and 6 panels successively. However these products should not store for more than a day due to the fact that microbiologically total viable count would be exceeds specified standard by a day.

This paper presents a prototype of solar powered aerator for public reservoir which consist of three main parts first aerator-venturi type second electrical system from solar panels and third floating structures. The proposed aerator has been adopted from an used electric water pump to have a water inlet an air inlet and mixture air and water outlet releasing bubbles through under water. Electrical system acting as the core energy resource receives light of solar energy via 2x120 watts solar panels and then accumulating the obtained electric energy to battery. The 24-volt battery will supply power to 150 watt directed current motor for driving the venturi aerator. To archive evaluation the combined aerator with solar system has been installed at Nong Luang reservoir in Muang Tak province and has operated for 30 minutes. To collect water samples have been done twice times at before and after operation. The obtained laboratory results show that dissolved oxygen (DO) increased from 0.87 mg/l to 3.56 mg/l and the biological oxygen demand (BOD) decreasee from 9.7 mg/l to 7.2 mg/l. According to the results it confirms that the proposed solar powered aerator for public reservoir can operate efficiently and independently.

The purposes of this research were as follows: 1) to construct and find an efficiency of the development of social service model instruction to enhance public consciousness on sufficiency economy for bachelor students as the 80/80 standardized criterion efficiency 2) to find the effectiveness index of the development of social service model instruction to enhance public consciousness on sufficiency economy for bachelor students 3) to compare pretest scores and post-test scores all lessons 4) to study the satisfaction of students after they join the class 5) to study the attitude of students after they join the class and 6) to find the retention of students after join the class in two weeks. The sixty students were area on simple random sampling selected from students in Rajamangala Technology University. The results the study was as follows: 1) An efficiency of the development of social service model instruction to enhance public consciousness on sufficiency economy for bachelor students was 82.54/82.11 which higher than the 80/80 standardized criterion efficiency. 2) The efficiency index of the development of social service model instruction to enhance public consciousness on sufficiency economy for bachelor students was 0.7246. 3) The results of the comparisons of pre-test scores and post-test scores all lesson significantly different at 0.05. 4) The results of the satisfaction of the development of social service model instruction to enhance public consciousness on sufficiency economy for bachelor students was found to be a high level. 5) The retention of the teachers after join the class in two was no significantly different.

The objective of this research was to study environment changes in orchards by using wireless sensor network and spatial data interpolation technique. The study was conducted by distributing several client sensors into the two study areas for recoding temperature himudity and light internsity. These data are send to a server using 433 MHz radio signal. The results from the first study area in Thachang District shew that the light intensities were significantly changed during 6:00-6:59 11:00-14:00 and 18:00-19:59. For the humidities they were significantly changed during 7:00-8:59 17:00-19:59 and 22:00-23:00 which were quite different from the changing of light intensity. Lastly the temperatures were mostly changed during 7:00-7:59 10:00-14:59 and 18:00-19:59 which were highly related to the changes of light intensity. For the second study area in Angkhiri District light intensities were significantly changed during 7:00-7:59 11:00-14:00 and 18:00-19:59 while the changing durations for the humidities were 9:00-9:59 12:00-15:00 and 17:00-19:59. Very similarly to the light intensity the temperatures were changed during 8:00-8:59 11:00-14:59 and 15:00-17:59. For the communiation distances the maximum distance for transfering data in an open area was 100 meter and 25 meters with obstables.

The reduction of calcium carbonate (CaCO3) particle was prepared by wet grinding method with 40% dispersion. The particle sizes of CaCO3 were studied with various time of wet grinding. It was found that the particle sizes of CaCO3 rapidly decreased in 3 day of grinding after that it was slightly reduce. Therefore the CaCO3 at various time of wet grinding were mixed with concentrate latex (60% dry rubber content DRC). The result showed that the wet grinding for 2 days provided the superior machanical properties. In addition the compound with epoxidized natural rubber (ENR) as a coupling agent was investigated. It was found that the 5 phr of 30% mole percent of ENR results in significantly improved mechanical properties of the rubber vulcanizates.
