The study and Development Lightweight growing media by Coir to use a Vertical garden.To create thermal comfort for building users are the main factors causing the air conditioning. The cause of the electrical consumption. Thus bringing the tree into the building. In the past the building that used tree. Create a homey Subsequently it has adopted a large tree used for the purpose of lowering the temperature of the surrounding buildings. Developed into a roof garden Reduce heat to pass through the roof. And is currently being applied in the manner of a green wall. This helps reduce the heat that enters the building through the building envelope as well. The behavior of the tree to absorb water from the roots to the leaves and then passed to photosynthesis. Such a process makes the water evaporates and the air has been cooled by the surrounding trees The Heat pulled away for the evaporation of water. Such a process which happens from time to time no matter how much humidity in the air. The cool environment is another factor that manipulates the ambient environment to environment and buildings The benefits of trees in the green areas of the city this is helping to reduce and prevent the phenomenon of urban heat island The study and Development Lightweight growing media by Coir to use a Vertical To reduce the weight of structural data were collected to design the plant material. Then the data from design professionals and vertical landscaping questionnaire. And interviews to analyze the result. And amends To test plant material vegetation series of 12 trials by planting vegetation. On the wall a series of three experiments wall. (Width 1.20 m. Height 3.00 m.) Of the test data and the growth of vegetation. Found that plants grow well on a series of plant material. The unit is lightweight and planting is not burdened with the weight of the building structure.

The research products of chili fried watermelon rind remains were found. The decent amount enhancing of the watermelon rind in fried chili pastes are 25% 50% and 75% of total weight. The results show the 50% enhancing of the watermelon rind in fried chili pastes all of sample such as roast chili paste fermented fish chili paste Tadand chili paste and Oong chili paste were recognized in the like moderately-like very much. Increase of watermelon rind at 75% of total weight the acceptance is decrease. The texture of samples of fried chili pastes enhancing of the watermelon rind show that 1035.74-1901.16gram of the consistency -132.16- -98.07 gram: milligram of the cohesiveness and 2.15-5.67 gram of the viscosity. The chemical composition of fried chili pastes enhancing of the watermelon rind show that the 50% of watermelon rind in roasted chili pastes were 233 Kcals of total energy 7.20 of protein 9.56 of fat 4.83 of ash 29.60 of carbohydrate and 7.09 of crude fiber. The 50% of watermelon rind in fermented fish chili paste were 152 Kcals of total energy 5.93 of protein 5.60of fat 4.21of ash 19.4of carbohydrate and 5.41of crude fiber. The 50% of watermelon rind in Tadand chili paste were 183 Kcals of total energy 6.68 of protein 3.26 of fat 7.34 of ash 31.80 of carbohydrate and 11.10 of crude fiber. The 50% of watermelon rind in Oong chili paste were 182 Kcals of total energy 6.77 of protein 12.80 of fat 2.61 of ash 9.92 of carbohydrate and 3.21 of crude fiber For the technology transfer of Fried Chili paste from Watermelon Rinds Waste to Center Concert career womens groups Don Kang. The participants were satisfied with the course of 92.67

The objectives of this research are to study the production to find the proper ratio to test the physical mechanical properties and thermal conductivity to suggest the implementation and to transfer the technology of light-weight precast concrete wall panel products mixed with container foam wastes. Design the ratios of Portland cement type1: coarse sand: lime stone: water equal to 1: 2: 4: 0.7 by weight and adding the container foam wastes equal to 0 0.025 0.050 0.075 and 0.1 by weight. Casting the light-weight precast concrete wall panel products by pouring the concrete into the mold which installed the steels. Test the properties follow TIS.2226-2548 and TIS.878-2537. From the results the proper ratio of adding container foam wastes was 0.075 by weight which had perfect general characteristic 16.48 MPa of compressive strength no bending when installed in common behavior 8.86% of water absorption passed type1 of hardness test passed type 2 of impact test 2014.54 kg/m3 of density 4.30 MPa of bending strength and 0.228 watt/m.K of thermal insulation. This light-weight precast concrete wall panel product can use as the thermal insulation wall in building. Moreover the developing product can apply to register the petty patent.

การเปรียบเทียบค่าความสัมพันธ์ระหว่างความเค้นและความเครียดที่ได้จากการทดสอบแบบเป่าโป่งด้วย น้ำกับการทดสอบแบบแรงดึงแกนเดียวของสแตนเลส SS304

The purpose of this research is to find the relation between stress and strain called as the Flow Stress Curve for 0.4 mm thickness stainless steel (SS 304). Two main methods are used: the Uniaxial tensile test and the Hydraulic Bulge Test (HBT). The relation between stress and strain from both methods would then be compared and simulated into cubic-shaped models by using Finite Element method. Results show that sheet metal formation simulated by using the flow stress curve obtained from Hydraulic bulge test can have the height of up to 40 millimeters before the work piece starts to lacerate. On the other hand if the flow stress curve obtained from Uniaxial tensile test is used the work piece will only be able to form about 15 millimeters before lacerating. The preliminary summary for this research can be said that the analysis for Hydraulic bulge test gives better results than Uniaxial tensile test as it has similar conditions to the actual formation process.

Currently transport has played an important role in everyday life resulting in huge traffic jams caused by big city streets and pollution problems from global warming to global temperatures are rising. Since humans are creatures that prefer comfort in all areas which contrasts with the higher temperatures of the Earth. Currently the use of air conditioning a lot. To modify the temperature is reduced in the range 2 3 to 25 degrees Celsius makes people feel comfortable. However the use of air conditioning in the car cabin cooling efficiency can be increased to a higher level than it is by cooling the refrigerant. The aim of this research is to test and compare the performance of car air conditioning systems usually equipped with a heat exchanger. Using water from the condensation of evaporator as a medium for heat transfer. By installing the equipment at the outlet of the condenser. This causes the temperature of the refrigerant is low. The pipe lengths in the equipment from the calculation of 1 .2 meters and copper lines that increases the length of the tubes was calculated to compare with a length of 1.6 meters to test the speed of the compressor 1000 1500 2000 and. 2500 rpm and a wind speed of 20 35 and 50 kilometers per hour. The results of experiment found that the temperature refrigerant equipment decreased from an average of 1.6 degrees Celsius the pipe length of 1.2 meters and 1.6 meters of pipe temperature drops 1.8 degrees average temperature attended Eva sufficiently reduced operator. It increases energy efficiency ratio averaged 6.68% of the pipe length 1.2 m and 22.24% at a length of 1.6 meters as well as to increase the coefficient of performance of the air conditioning system. 6 .6 9 % of the pipe length of 1.2 meters and a length of 1.6 meters at 22.4% with the key factor in optimizing the cars air conditioning system. Making the refrigerant from the condenser the temperature drops to pull heat out of the cabin through evaporator higher.
