This research is to study the quality development of silk fibers by nanotechnology for the Silkworm farmer business groups of Surin Province. The research purposes are to study the efficiency and process of silkworm rearing using nanotechnology. To test the quality of silk fibers obtained from raising silkworms using nanotechnology. To compare of silkworm rearing results using nanotechnology and to transfer technology to improve silk quality with nanotechnology for silkworm farming business group in Surin Province. The results are as follows 1. The researchers designed the recording schedule which the party can record the changes easily of silk worm development during each day. This research allows the researchers to collect data from the farmer is more easily and finely into 4 groups of experiments with 3 nanotechnology formulas: 1. ZINC OXIDE 2. SILVER NANO and 3. ZINC OXIDE and SILVER NANO with 50:50 percentages each. The silk used in the experiment was “Nang Noi” which is popularly silkworm variety in every household in Surin province.When experimenting must clean the house and rinsing the container with DI WATER for aperiod of 7 months 2. This research is divided into 4 groups. Group 1: Silkworm feed normal methods without the use of nanotechnology. Group 2 silkworms feed with Nano substances such as ZINC OXIDE SILVER NANO ZINC OXIDE and SILVER NANO in 15 percentage concentration. Group 3 silkworms feed with Nano substances are ZINC OXIDE SILVER NANO ZINC OXIDE and SILVER NANO with 30 percentage concentration. Group 4 silkworms feed with Nano substances are ZINC OXIDE SILVER NANO ZINC OXIDE and SILVER NANO with 45 percentage concentration 3. The Results and comparison of silkworm rearing using nanotechnology the best formula feed is formula 1. When feeding Nano-sprayed on mulberry leaves using 3% 15% zinc silver and silver zinc it is found that the growth of worms in each age was good growth and not being a disease. Moreover Silkworms are slightly better and more alert than normal farming. The length in ages 3 - 4 - 5 is going in a better direction. Amount of eating mulberry leaves in each age. As usually eating more in ages 2 and 3 after passing the silk production process and testing the quality of silk fibers in the laboratory were found that the silk fibers are smooth not lacking toughness: Tenacity at 3.06 4.60 and 4.60 respectively and also result in fiber amount increase and also the color of the silk fibers is golden quite clear beautiful and consistent color. 4. When technology transfer to the Silkworm farmer business groups of Surin Province as workshop for 3 days. Most participants are satisfied with the highest levels in all questions.

The objectives of this research were to determine the suitable times of pork slices drying using microwave followed by hot air and to find specific energy consumption during drying. The physical characteristic (color and hardness) and the sensory test of dried pork slices were also investigated. Pork slices with the sizes of 50x50x1.3 and 50x50x2.2 millimeters were dried using the microwave at the powers of 160 320 480 640 and 800 watts until the samples did not burn during drying. Then the samples were dried using hot air at a temperature of 110oC until the moistures of the samples were lower than 20% dry basis. Based on the experimental results it was found that the suitable times of the samples drying using microwave were 50-600 seconds which depended on the microwave powers and the pork thicknesses. In hot air drying period drying times of the samples with thicknesses of 1.3 and 2.2 millimeters were 30 and 45 minutes respectively. The microwave powers had no significant effect on the redness (a value) and yellowness (b value) of dried pork the hardness of dried pork and the specific energy consumption (P<0.05). The pork thicknesses had the significant effect on the lightness (L value) and yellowness (b value) of dried pork the hardness of dried pork and the specific energy consumption (P<0.05). Moreover sensory scores of the dried pork obtained from this research were close to those obtained from the local market.

This research aims to increasing efficiency in production and eliminate the problem of insufficient production capacity with respect to customer demand for electrical appliance factory by applying the line balancing method. Thus the study then developed two problem-solving approaches. The first approach is a method by which a firm applies the line balancing concept and ECRS technique (Eliminate Combine Rearrange and Simplify). On the contrary the second approach is required an investment in testing machine with value of 1000000 baht in order to support sufficient production capacity to meet customer demand. Also ECRS method is used to accomplish this process. Based on the results the first approach provided the production line efficiency improvement representing of 82.59% and reduced the labor cost of 277220 baht per year. However the loss of commercial opportunity has remained the same of 6336000 baht per year. Accordingly the second approach demonstrated of 92.11% of the production line efficiency improvement and the labor cost reduction valued of 277220 baht per year. As we expected the second approach satisfied production efficiency by eliminating the loss of commercial opportunity with value of 6336000 baht per year delivering a return of investment within two months.

Aluminium was used in many industrial applications due to good properties such as ductile high corrosion resistant and high electrical conductivity. Since wear resistance of aluminium was very poor so that it was a limitation of using this material in several conditions. In this research aluminium was improved the wear resistance properties by using anodizing process and adding some titanium dioxide particles on the surface. The effect of anodizing process duration on the wear resistence property was studied. It was found that the process duration and amount of titanium dioxide play the important role on improvement of tribological properties of aluminium.

Silica is an amorphous and nanometer scale voids and porous form of silicon dioxide. As long known for its high specific surface area synthetic silica has been used to adsorb water readily and applied for keeping many biological products dry protecting equipment from moisture damage. In the study the researchers have interested in making the tentative eco-friendly dehumidifying products based on the silica extract from bamboo leaves. The extraction procedures were performed by boiling dry bamboo leaves with various concentrated hydrochloric acid (HCl) at 1 2 3 and 4 M then burning them at 650oC for 4 hr before analyzing the purity of the biosilica with the X-ray Fluorescence Method. The results showed that the highest purity of the biosilica sample at 96% could be obtained after treated with 4 M HCl comparing with the control commercial silica. By hygroscopic test the extracted biosilica with 2 M HCl showed the highest moisture absorption properties close to the commercial silica. While the highest adsorption capacity was found in the biosilica sample treated with 3 M HCl. The dehumidifying efficiencies of all HCl treated biosilica power were not much different comparing to the commercial silica gel. Instead of using synthetic silica therefore this high environmentally friendly and cheaper biosilica from bamboo leaves can preferably be decent and further applied in green industry.
