The objective of this research is to investigate microstructure and mechanical properties of brass welded by diffusion welding process. The diffusion welding (DW) of brass welded over lap joints bonding parameters were pressure at temperature 500 650 and 800 0C contact pressure of 12 MPa and holding time for 60 minutes respectively. The microstructure mechanical properties and behaviour during bonding were investigated. The results show that in weld zone (Bond Line) diffusion of atom the brass significantly. The mechanical properties after diffusion welding process increased higher temperature

This paper presents a study of heat exchanger design for improving the performance of ice maker by using waste water from ice factory. The heat exchanger was made of stainless steel and had 4.023 m2 of heating surface. After using the heat exchange in the waste water pond which the temperature was 0 C the temperature of feed water was decreased from 28 C to 22 C. The COP of the ice maker was increased and the factory can save energy consumption 52034 kWh/year or 61993 baht/year. The payback period was 0.5 year

The purpose of the research was to study the exciting permanent-magnetic-field affecting to the Bean Sprout growing. The comparison of control-group (or unexcited seed) of the Chainat-72 seed and exposure-group seed where is the excited by the 1.6-Tesla permanent-magnetic-field of 15 30 45 and 60 min has been done. The exciting permanent-magnetic-field affecting to the Bean Sprout growing is analyzed by statistical analysis. The findings revealed that: by excited seed the maximum grow-up rate or average weight of Bean Sprouts was 24.82 %.

The purpose of this study was to study factors affecting the personal financial management of personal in Rajamangala University of Technology in Bangkok area. These factors were divided into 4 factors; first of them was personal factor: age academic position and salary second of them was family factor: family responsibility third of them was environmental factor in the workplace: imitation to their peer groups in office and fourth of them was factor of social environment: the influence of the media. The samples in this research were 334 personals. The study participates selected by stratified random sampling. The Instruments used in this study were the interview and rating scale questionnaire 5 levels of 16 items discrimination since 0.31 to 0.69 and alpha coefficient of 0.86. Percentage mean standard deviation χ2 - test and stepwise multiple regression analysis were statistical method to analyze data. The results were as follows: 1. The personal factor: age academic position and salary no related to the personal financial management of personal in Rajamangala University of Technology in Bangkok area. 2. The factors related to the personal financial management of personal in Rajamangala University of Technology in Bangkok area statistically significant at the level of significant 0.01 in the order correlation coefficients (rxy) descending as follows: family factor (0.556) environmental factor in the workplace (0.295) and factor of social environment (0.120) 3. The factors which could predict the personal financial management of personal in Rajamangala University of Technology in Bangkok area at the 0.01 level significant: family factor (X1) and factor of social environment (X3) with the multiple correlation coefficients (R) of 0.627 and coefficient of determination (R2) of 0.393. The predicted equation of affected the personal financial management of personal in Rajamangala University of Technology in Bangkok area at 0.01 level were as follows 3.1 In terms of raw scores were : yˆ = 0.776 + 0.700x1+0.085x3 3.2 In terms of standard scores were : Y = 0.553x1+0.289x3

The objective of this research was to investigate the factors that effect the study result of 467 Rajamongala university of Technology Pranakhon students who studied the Principles of Accoutning subject in the academic year 2013. The questionnaires were used for data collection and the multiple regression was used for data analysis in order to find the factors that effected the study result. The study found that with the total study score of 100 the maximum score was 85.76 the minimum score was 42.58 the average score was 65.812 and the standard deviation was 15.73. The results of hypothesis test were as follows: The factors that were related to the study results (Y) were student attitude ( x ) student responsibility ( x ) teaching method ( x ) and out of class activity ( xo ) with the correlation coefficients of 0.853 0.801 0.874 afi0.791 respectively. The most effective factor was student responsibility with the regression coefficient of -18.231 the second and the third most effective factors were student attitude teaching method and out of class activity with the regression coefficients of 14.4269.133 and -4.062 respectively. The multiple regression *u f = -9 .228 + 27 .319x + 9 .ll6x + 2.499x .
