Here we present an experimental study of the single-effect adsorption cooling system using activated carbon-methanol working pair. The test unit was comprised of an adsorber a condenser and evaporator in vertical alignment. Heating and cooling of adsorber was mainly done by hot and cold water circulating through the water jacket. The evaporator and condenser was heated or cooled by flows of water through the internal coil. The adsorber was analyzed for its cooling rate when cooling was done by two approaches either cooling water and/or three thermosyphon heat pipes which both methods gave shortest cooling time. The investigated heat source and sink temperatures are; hot water temperature supplied to adsorber (70 80 90 oC) and cooling water temperature supplied to condenser (5 10 15 oC). An ultrasonic wave generator was attached to the bottom end of the evaporator to generate wave frequency varied by 8 10 and 14 kHz during evaporation phase. The ultrasonic wave can obviously reduce the evaporation time of methanol as well as to improve the system performance in terms of COP SCP and VCP. The system performance was considerably comparable to those from literatures. The highest COP and SCP obtained from this system was 0.718 and 248.90 W/kg respectively.

Rajamangala University of Technology Bangkok (2) to compare the views of students on performance of the registration and processing. Promote academic and Registration Office. Rajamangala University of Technology Bangkok by (gender age class year the Board the number of times to contact) of the students. The samples used in this study is the undergraduate representative to the event registration service and processing. Promote academic and Registration Office. Rajamangala University of Technology 400 Total capital is calculated using the formula provided by Yamane sample size is the confidence level and 95 per cent margin of error not exceeding 5 per cent on the tools used to collect information on the research questionnaire is created. The data was analysis using SPSS program for the result of average percentage standard deviation values. And test different ideas of students in the performance of the registration and processing. Distributions using a (t-test) and F values (F-test) Remuneration expressed the importance of statistics equal 0.05. The research found. (1) The sample with comments on the performance of the group. Registration and processing operations in the medium is equal to the average 3.28 (2) personal factors including gender age level of contact of the number of times the level of customer satisfaction performance for the registration and processing. Promote academic and Registration Office. Man~gement operations are not different as statistically significant level of 0.05.

The purposes of this research were to study the performance of Buddhism schooling under the jurisdiction of Bangkok Metropolitan Administration and to study problems obstacles and suggestions about the performance of Buddhism schooling. The examples were 202 principals of schools using simple random method. The analytic methods were percentage standard deviation t-test and one-way analytical of variance (ANOVA). The results of study found that the performance of Buddhism Schooling under the jurisdiction of Bangkok Metropolitan Administration as a whole was at the highest level. The comparison of principals of Buddhism schooling classified by sex level of education and experiences of administration found no difference. The performance problem of the principals in Buddhism Schooling found that students could not understand the reasons and the real value of the three kinds of knowledge for deliverance (Trisika) correctly.

This research objective was to design the ginger candy compression machine and determine the efficiency and capacity for saving time and labor in pressing ginger candy for community enterprise groups Pim Malaherb Chiang Rai Province. Ginger candy compression machine consists of the main structure namely the extruder and power transmission systems. The machine was designed with two horsepower motors or 1.5 kilowatts to drive the shaft and to rotate the screw through the flange. This study installs the inverter to control the motor speed at 1000±10 1200±10 and 1400±10 rpm. The extrusion die had an average diameter of 9.7 millimeters. The results found that the motors speed that was suitable for compression was a Rotational speed of 1400±10 rpm. When the speed increased the efficiency and the working rate increased too. The amount of ginger stirred was used at 300 500 600 900 1000 1500 2000 and 3000 grams. The maximum efficiency was 90.85 percent. The efficiency increased with the amount of ginger stirred. The ginger candy compression machines engineering economic analysis results found that the machines operating cost was 18063.6 baht per year. When considering the machines operation at 792 hours per year the payback period was 6 months and 11 days.

This research study is Study of Current Problems Obstacles to the work of the academic faculty. To analyze the factors that affect the potential success of the work of the academic faculty. And to formulate a strategy to build the capacity to do the work of the academic faculty. Faculty of Liberal Arts Rajamangala University of Technology Phra Nakhon. The researchers mixed Quantitative and Qualitative Research Questionnaires were used to collect data from administrators faculty the Faculty of Arts. The researchers mixed Quantitative and Qualitative Research Questionnaires were used to collect data from administrators faculty the Faculty of Arts. 60 people and the depth interview interviewed individually to provide a significant number of 10 people. The data were then checked for accuracy. And data analysis and processing computer To calculate the statistical. Frequency percentage mean and standard deviation. And qualitative data Checked for accuracy by means of triangulation. And content analysis With reading comprehension The purpose was to research. The results showed that Current conditions in the academic faculty have discussed the barriers. Have success in the academic performance of 83.33. The lower third of the academic performance of 80.00. And four consultants to advise on the Academic Performance 76.67 percent. And the two taught 75.00 percent. The factors that affect the potential success of the work of the academic faculty. Overall the high level (= 4.48 SD = 0.65).The five factors that make success in academic performance. Situated at the highest level (= 4.81 SD = 0.40). The second is the time to do academic work at the highest level (= 4.79 SD = 0.47) and quality of academic performance. Situated at the highest level (= 4.64 SD = 0.52). And a consultant to advise on the Academic Performance. Situated at the highest level (= 4.56 SD = 0.80). The strategic potential of the academic performance of students. Overall the moderate level (= 3.43 SD = 1.13). The strategy should define ones executives must have a policy seriously. And to be fair to the sender academic performance. The second strategy should reduce the workload for faculty teaching and other work with. In order to have time to do academic work. Strategy three awards to supply support for the preparation of the appropriate academic achievement and extra salary. And strategies for the five should be evaluated on a fair transparent fair assessment. The main good governance in the assessment. Transparency accountability Without prejudice to rate Teachers have the opportunity to make changes to the criteria at all times. 6 and strategy should provide consultants to advise on the academic performance of each branch. The guests were delighted. And it is time to provide advice in a friendly and should be coordinated with the technical evaluation. Or monitoring academic performance in applying the criteria in the evaluation. In the same manner and justice. There are good governance.
