การทอผ้าขีดลายไทยเพื่อออกแบบและพัฒนารูปแบบผลิตภัณฑ์สิ่งทอ
The objective of this study was to khet design by using Thai pattem created on cotton clothes using Thai Khet creation: warp yarn in thousand comb with tightly strengthened cloth while welf yam with hardness together Thai Khet on Thai cotton pattern Traditional Thai Khet waving machine to be adapted by adding front floating hardness pattern hardness wood stepping new pattern weaving plan plotting Thai pattern and making color signals on graph prior khet pattern creation which one graphs column replaces one warp yarn when khet designing have been finished then the following step is desinged plane weaving. The results of the study showed that: there is suitable continuing Thai pattern on cotton cloth: Kanook pattern follows Krajang Ta Ooy pattern and Prajamyam pattern to be combined as graceful delicacy pattern and innovation transferred into Danchang District Supanburi Province.
Development of concrete boat by using lightweight concrete
The objective of this study aims to develop a concrete boat by using lightweight concrete. The use of granular foam replaced the aggregate in various quantities to reduce the weight of boat. The replacement ratios of aggregate by the granular foam were 0 25 50 75 and 100% by volume of aggregate. The test results of compressive strength tensile strength modulus of rupture and unit weight of concrete were used to find out the appropriate mixture for producing the concrete boat. The results indicated that the appropriate mixture for producing concrete boat was the replacement of aggregate by granular foam at 100% which had the compressive strength at 28 days of 50.59 kg/cm2 and the unit weight was 949.71 kg/m3. The weight of lightweight concrete was lighter than the normal concrete about 57%. The prototype of lightweight concrete boat which had 1.04 m wide 2.20 m long and 0.38 m height had about 50 kg of weight. The maximum weight capacity of the boat was 240 kg. The cost of a lightweight concrete boat was about 650 baht
Search engine use behaviour and the use of web search tools on google of elderly in Bangkok
The research about behavior and using instrument for search data through the Google Website of the elderly in Bangkok which the results of research can summarize by following: most of the representative samples were female 204 people and mainly education in undergraduate there was trade career and private business average income per month between 20001 – 30000 THB. with the knowledge and skill to use the computer in the middle level. And has a personal E-mail address which mainly uses the Internet for a period of less than 5 years and now living with the family their hobby after retirement is planting trees. They had learned to use computer from the family’s members. And in the attitude towards the search data through the Google Website has found that the representative sample’s attitude towards the search data through the Google Website at a high level. In the behavior of using has found that the most of use the Google Website for 1 – 2 years and in using of instrument for search data has found that the use of search data through the Google Website at a low level.
Dry reforming of methane reaction for hydrogen and syngas production using cobalt catalysts and nickel-cobalt bimetallic catalysts
The cobalt catalysts (cobalt content by weight: 7% 10% and 15%) and cobalt-nickel bimetallic catalysts (cobalt-nickel content by weight: 3.5%-3.5% 5%-5% and 7%-7%) were studied in dry reforming of methane for hydrogen and syngas production. All catalysts were synthesized by the wetness impregnation method. The dry reforming of methane was carried out at 700oC atmosphere pressure using a mixture; CH4 and CO2 in ratio 1:1. The result showed that the good activity and stability depend on metal content in catalysts and the combined 2 metals as bimetallic catalysts. The optimum amounts of catalysts are 10wt% Co for mono-metallic catalysts 75%CH4 and 75%CO2 conversion and 7wt% Ni-7wt% Co for bimetallic catalysts 87%CH4 and 89%CO2 conversion.
Problem and obstacle in learning of student the faculty of science and fisheries technology, Rajamangala University of Technology srivijaya trang campus’ students
The objectives of this research had to study and compare the problem and obstacle of freshmen student who had studying achievements lower than 2.00 in 3 aspects: the student teaching and studying environment aspect variable classified by sex and major. The research group was the freshman students of the Faculty of Science and Fisheries Technology Rajamangala University of Technology Srivijaya Trang Campus and their studying achievement lower than 2.00. Interviewing was used the research material. The results showed as following: Problems and obstacles which had the most effected to the research group was the student espect for example basic knowledge living adjustment of student lack of motivation and enthusiasm to learn as well as teaching and studying aspect for example lecturer’s inadequate teaching methods respectively. Comparison between problem and obstacle of freshmen student who having studying achievements lower than 2.00 classified by sex and major was found that the different of sex had no statistical significant difference in all and each aspects. In addition the different of student’s major had no statistical significant difference in all aspect. Contrast to in each aspect the studying environment aspect was found statistical significant difference at the level of .05.
