The purposes of this research were to make artificial wild orchids from joint-vetch to imitate the natural one. Researchers studied joint-vetch dyeing Thai wild orchids forming from joint-vetch Thai wild orchids selecting by considering appropriate appearance shape and composition and five experts gave the opinions on the chosen researched orchids. The development of wild orchid product from joint-vetch was transferred to housewife’s group in Phra Nakhon Si Ayutthaya province. The satisfaction of the research product was investigated from 60 target groups. The overall satisfaction of the participants after attending the training course was at the high level (4.73). Other aspects were found that the average mean (4.74) of the facility was at the highest level. The average mean (4.73) of the knowledge application was at the highest level. The average mean (4.71) of the product was at the highest level. The average mean (4.68) of the instructor was at the highest level. The average mean (4.35) of the understanding was at the high level.

This paper is proposed a compressor of spilt type air conditioning modification for using with variable speed drive to control room temperature. This technique is implemented by modified reciprocating compressor of 220 V single phase air conditioner 12500 BTU to 3 phase 220 volt in order to connect with inverter variable speed drive which has input 220 V single phase and output 3 phase 220V. The result of experimental is found that modified compressor can be operated in normal condition at maximum speed. The suction pressure is 65 psig discharge pressure is 250 psig and mean of motor current is 6.48 Ampere. The proposed modified compressor can be applied with conventional split type air conditioning by change the starting method from direct start online into soft start with variable speed drive

This experiment was conducted to study on single cell protein production from copra meal residue by Saccharomyces cerevisiae and Bacillus subtilis as animal feedstuffs. The experimental design was 4x3 factorial in CRD experiment with two factors were design to experiment. The first factor was comprised of fermented period (0 15 30 and 45 days). While the second factor B was comprised of microorganism type (Saccharomyces cerevisiae Bacillus subtilis and Saccharomyces cerevisiae combined with Bacillus subtilis). The results showed that interaction between factor A and B on pH (4.00-4.53) and percentage yield (29.21-33.80) were highly significantly different (P<0.01). However Incubation temperature were not related between factor A and B. Additional both factor have no effect to incubation temperature (P?0.05). For nutrients composition the group was fermented Saccharomyces cerevisiae combined with Bacillus subtilis showed higher Crude Protein than other treatments (P<0.01). Optimum of period at days 45 showed that crude protein 14.77 percent was significantly (P<0.01) and pepsin digestibility 66.60 percent was significantly (p<0.01)

A comparative study. The purpose was to study the costs and the cost of return. Comparative analysis of the difference between revenue and the cost of return breakeven Between brackish and salt water fish white snapper. This study used data from interviews with of 24 cases. The period 6% of Interest rate of study 5-year. - A study of the brackish cost per acre was 355127.00 baht Salt water 31556.34 baht cost was 850784.15 baht Salt water 788305.00 baht Income yield 1914250.00 baht. and Salt water 1908750.00 baht. the cost according to the net present value (NPV) were positive value equal 620881.68 baht Salt water 628974.65 baht and the internal rate of return (IRR) 16.95% Salt water 17.45 % with a payback period of 1 year 9 months 6 days Salt water 1year 8 months 4 days and the breakeven point is equal to 96529.25 baht Salt water 86643.80 Baht. - The salt water yield worthwhile than brackish water.

The purpose of this research work was to synthesize titanium dioxide supported on activated carbon and used it as a catalyst for dye decolorisation. The effect of preparing factors on titanium dioxide supported on activated carbon such as calcinations temperature and the amount of carbon supports were investigated at 300 400 and 500OC and in range of 5-30 percent by weight respectively. The X-ray diffraction (XRD) technique was used to detect the crystal structure of prepared catalysts. It was found that all peaks were anatase phase. The morphology of these catalysts was analyzed by scanning electron microscope (SEM) and transmission electron microscope (TEM) techniques. The results showed regularly distribution of titanium dioxide supported on activated carbon. The particle size of obtained catalysts was 5-10 nm. The Brunauer-Emmett-Teller (BET) technique was analyzed physical characteristic of catalysts. The specific surface area average pore diameter and pore volume of catalysts was 151.02-784.13 m2/g 26.94-64.35 and 0.24-0.55 cm3/g respectively. Furthermore the activity of obtained catalyst was carried out by using these catalysts to decolourise dye aqueous solution. The titanium dioxide supported on activated carbon 20 percent by weight can obtain 99.78% decolourisation at dye concentration 75 mg/L catalyst concentration 0.5 g/L within 90 minute. Comparison with titanium dioxide P25 (commercial grade) titanium dioxide supported on activated carbon has higher ability. This is because it was not only photocatalytic reaction but it was also absorption
