The research in the aim for useless material from cashew nut shell produce are heating energy briquettes to use recompense energy fine wood and charcoal from natural. By the flour paste is join together pass procedure heating briquettes with hand press implement. It is cashew nut shell can make to burn with earthen stove high temperature stove and steel stove from cashew nut shell are still shape and have bring into fine crush machine receive dust charcoal. It is mixed dust charcoal with flour in ratio 5:1 (by melt flour into hot water one liter until flour paste) mixed and bring into heating briquettes with hand press implement receive heating energy briquettes are no broken. When we bring expose to the sun until dried. After that to test efficiency of heating energy to see that cashew nut shell can to produce are heating energy briquettes. It use heating energy in home family in community replace to use from fire wood and charcoal from natural and heating energy briquettes from cashew nut shell can to use a make cooking well no broken fire well and height heater. It is suitable to produce heating energy for to use home family communities or commercial production and industries are use heating energy from fire wood and charcoal.

The objectives of this research are: to study the characteristics of students in the Faculty of Engineering at Rajamangala University of Technology Pra Nakorn North Bangkok Campus that influence to the risk of withdrawal from Calculus 2 for Engineers; to predict the risk of withdrawal from Calculus 2 for Engineers; and to use the results of the study for planning and solving the problems of withdrawal from Calculus 2 for Engineers. The sample is 226 students in the Faculty of Engineering at Rajamangala University of Technology who enrolled the Calculus 2 for engineers in the second semester of the academic year 2009. The data are from the questionnaire. The factors considered are grad point average the number of enrollments for the Calculus 1 for engineers Calculus 1 for Engineers grade the number of courses that emphasize on calculation that were enrolled in the second semester of the academic year 2009 the sacrifices of students for the Calculus 2 for Engineers course and the need to withdraw from Calculus 2 for Engineers course before other courses. The logistic regression model in which the parameters are estimated by using Bayesian methods is used for analyzing the data. The study shows that the factors that influence to the risk of withdrawal from the Calculus 2 for Engineers are grade point average Calculus 1 for Engineers grade the number of courses that emphasize on calculation that were enrolled in the second semester of the academic year 2009 and the sacrifices of students for the Calculus 2 for Engineers and the need to withdraw from Calculus 2 for Engineers before other courses. The factor that does not influence to the risk of withdrawal from the Calculus 2 for Engineers is the number of enrollments for the Calculus 1 for Engineers.

The experimental models of electric fields were set up by using 4 forms of electric poles a point - point point - rod parallel rod and coaxial ring. The equipotential lines and electric line of force were drawn by using Microsoft Office Visio Program 2007. The drawing of equipotential lines and electric field had shown the direction of electric field moving from the positive electrode toward the negative electrode and perpendicular to the equipotential line. The point - point poles in 10 cm. distance have constant and the highest electric fields which is 28.64 V/m. The electric fields of point - rod parallel rod and coaxial ring are 60.51 V/m 45.81 V/m and 181.98 V/m respectively.

The purposes of this research were to study of chemicals management problems in Thailand s higher educational Institutions. It also focused on comparing of problems level of teachers who were different in sex age educational level Institutions and chemistry teaching experience. The sample of this research was 205 chemistry teachers in the Department of Chemistry Faculty of Science from 14 Institutions in Bangkok and in related other areas in Thailand s Higher Educational Institutions. The instruments used in this research were the questionnaire of 5-rated rating scales of those 4 categories. The reliability of the questionnaire was that the storage of chemicals 0.80 the using of chemicals 0.75 the disposal chemicals 0.84 the chemicals hazardous prevention 0.79 with the total average of 0.82. The data were analyzed by Statistical Package for the Social Science for Windows(SPSS for windows). The statistic used was mean standard deviation Hest one-way ANOVA and Tukey HSD of Multiple Comparison Test. The results of the research were: 1. The chemistry teachers had the problems of those 4 categories of chemicals management of chemistry laboratories as well as the overall average value at the medium level. 2. The chemistry teachers with differences in sex had the problems of those 4 categories of chemicals management of chemistry laboratories as well as the overall average value of non-significant differences. 3. The chemistry teachers with differences in age had the problems of those 4 categories of chemicals management of chemistry laboratories as well as the overall average value of significant differences. 4. The chemistry teachers with differences in educational level had the problems level of the overall average value of significant differences in master educational level with doctoral and post doctoral educational level. 5. The chemistry teachers with differences in Institutions had the problems level of the overall average value of significant differences in old Institutions with Kingmongkok Rajabhat and Rajamangala Universites. 6. The chemistry teachers with differences in chemistry teaching experience had the problems level of the overall average value of significant differences in less than 5 year 5-10 year and.more than 10 year.

The purpose of this study. To create sound books for the blind to the blind students have learned. Listened to sound books. The knowledge about the course to determine the efficiency of computer technology and satisfaction. Of sound books. Record management by preparing a division title a body of knowledge topics. And explanations of exercises or reading record sheets for each of the slides were not reading books documents will continue throughout. Daisy produced using data recorded on a VCD disc audio and text content knowledge displayed simultaneously and then applied to the sample. The elementary school years 4-6 After data collection ended. Teaching with the query. By a separate data reading. Reading divided by topics into each side. Students listen to the blind. A total of 38 data sets representing 84.44 per cent from the number of students and 45 students. The study found that creating audio books for the blind to blind students. Satisfaction levels in the average level of 4.15 and very good audio books build knowledge about the course of computer technology for blind people. Their knowledge of academic Ability to form and practice and performance satisfaction.
