This research is a qualitative research. The objective is to study and analyze information about The pattern of Pha Sin Tin Jok (Traditionally Sarong )Thai Yuan Saraburi cloth including the changes and the existence of the Thakok Thai Sarong Saraburi in the present (2017 - 2018). Using the concept of social and cultural change and the theory of globalization concepts for analysis. Research area is Mueang District and Sao Hai District Saraburi. The research population is Weaving sarongs Sarong user and local sages. Analytical study issues are Clothing culture in Thailand Saraburi Promotion from the government Pha Sin Tin Jok (Traditionally) Sarong Thai Yuan Saraburi style and pattern weavers and wisdom transfer. The research results are Saraburi is a province where Thai Yuan people from Chiang Saen Chiang Rai province Settled in the reign of King Rama I of Rattanakosin Due to war and have inherited the lineage until now. In Sao Hai District Saraburi is the district where most Thai people live and has a unique Lanna cultural foundation Whether language lifestyle food and beliefs In the folk textile Has a unique pattern that has been passed down for over 200 years. Clothing culture in Thailand Saraburi There is also a conservative costume. Especially on special occasions The pattern of Pha Sin Tin Jok (Traditionally Sarong )Thai Yuan Saraburi cloth remains the same style. From the era that migrated from Chiang Saen In addition there are other sarong fabrics that are used in everyday life namely woven sarong muk kai and kan. There is a succession of sarong weaving wisdom from the generation to the present most of which are woven with flowers. In the ancient pattern there is a conservation of ancient Pha Sin Tin Jok Thai Yuan Saraburi by re-woven according to the original pattern from the ancient Thai sarong that remains in Saraburi. Pha Sin Tin Jok Thai Yuan Saraburi has been promoted by various government agencies. There may be changes in the times that have changed with the adaptation to various product designs or the application of sarong work to the era. The existence of Thai people in Saraburi has seen the value of wisdom in their ethnicity. Together with promotion from various sectors That encourages Thai people to be proud Inspired in the conservation of Thai culture and arts. The establishment of Thai Folk Culture Hall in Saraburi The new weaving of the Sarawak sarong from the ancient Pha Sin Tin Jok Thai Yuan Saraburi style Including the floating market That shows the existence of the Thai culture of Saraburi living.
การศึกษาพฤกษเคมีและฤทธิ์ทางชีวภาพของสารสกัดจากมะพอกที่มีผลต่อการเจริญเติมโดของวัชพืชในนาข้าวเพื่อสนับสนุนการใช้ประโยชน์และเพิ่มมูลค่าความหลากหลายทางชีวภาพอย่างมั่นคงและยั่งยืน
This research aims to study phytochemicals and potential of Mapok (Parinari anamense Hance) extracts to inhibit germination and growth of Barnyard grass (Echinochloa crus-galli) a common weed in the rice fields. Organic solvents extracted the part of fruits barks and leaves of Mapok included hexane ethyl acetate and methanol. Crude extracts compose of fruit hexane extract fruit ethyl acetate extract fruit methanol extract bark hexane extract bark ethyl acetate extract bark methanol extract leaves hexane extract leaves ethyl acetate extract and leave methanol extract. Crude extracts were tested of phytochemical tested of germinating inhibition root length inhibition stem length inhibition and dry weight inhibition of Barnyard grass. Leaves ethyl acetate extract showed highest inhibit germination and growth of Barnyard grass The leave ethyl acetate extract was separated by column chromatography to yield nine fractions (F1 – F9 fraction) and tested inhibit germination and growth repeating. The results showed that 1. The crude ethyl acetate extracts from the bark of Mapok at a concentration of 3000 ppm showed the highest inhibited percentage of germinating inhibition root length inhibition stem length inhibition and dry weight inhibition. 2. Fraction F8 of leaves ethyl acetate extract showed the highest inhibited percentage of germinating inhibition root length inhibition stem length inhibition and dry weight inhibition.

The purpose of this research is to study on variables affecting fuel injection performance of biodiesel fuel injection and pyrolysis fuel. To test for variables affecting the fuel injection performance of biodiesel fuel injectors and pyrolysis fuel. By experimenting and modeling using computer programs to compare results. Finally for to use the information in the design of the car nozzle to work well with Biodiesel and pyrolysis fuel. The tested fuels which are pyrolysis fuel Bio-diesel fuel and diesel fuel are tested by tester Anton Paar@ Stabinger Viscosmeter (model SVM 3000/G2) ASTM D341 standard. The result shown that the density of the fuel is increasing normally. However the viscosity of the diesel and biodiesel are strong increased whereas the reducing of temperature is unaffected to the pyrolysis fuel. The fuel injection performance test showed that the density and viscosity of fuel were the major variables that affected the injection performance of the fuel. In case of using pyrolysis oil Injection performance is trend to higher other fuels and cold conditions.
การศึกษาพฤติกรรมการถ่ายโอนความร้อนในระบบเบรกเพื่อกำหนดค่าการนำความร้อนของผ้าเบรกที่เหมาะสม
Brake pad is a one of products that plays a role in the automotive parts industry and directly affects safety. Therefore there are many designs of brake pads for product development. This research aims to study the thermal conductivity of brake pads and define the thermal conductivity that appropriate to brake pads and also solve the problem of deterioration of braking automotive parts. To achieve this the 3 different ingredient brake pads from Compact International (1994) Co. Ltd. are studied in terms of the heat transfer behavior. The experimental work was set by simulating a brake on the single dynamometer at the braking speed of 50 100 and 130 km/h. As a results the significant parameters are copper and fillers respectively. It affects the heat transfer behavior by means of applying heat from the contact area between the brake pad and the brake disc to the caliper This knowledge will be used in the design of brake pad ingredients to determine the appropriate conductivity of the brake pads.

The results of the experiments were found that the temperature of the castings was higher than that of the silver alloys. The workpiece temperature is 500C the workpiece is good 26%. The workpiece is 74%. The temperature is 550C. The workpiece is 26%. The workpiece is 74%. The temperature is 600C. The workpiece is 40%. The workpiece is 60%. The workpiece is a fin. There are many factors that cause fins on the workpiece. Use of low-strength mortar In addition the use of excessive compression or heat transfer resulting in the expansion and shrinkage is not equal. This causes the cracking of the metal water to expand at a temperature of 650 ° C. The fine specimen 56% of the workpiece loses 44%. This temperature results in the smallest workpiece caused by the uneven surface. Cause of the cooling rate in each part of the casting is not equal. And at 700 degrees Celsius it is best to cast silver ornaments with pink color because the results show that the work is minimal. There are 70% good work piece 30%
