This research presents a study of the resistance to carbonation compressive strength and porosity of concrete containing ground bottom ash. Three different of bottom ash finenesses viz. coarse bottom ash (GBA-1) ground medium bottom ash (GBA-2) and ground fine bottom ash (GBA-3) were used for the study. Portland cement (CT) is partially replaced with ground bottom ash at 0-40% by weight of the bottom ash. The water to binder ratio was kept constant at 0.5. Compressive strength porosity and resistant to carbonation of concrete were investigated. Fine bottom ash has a high potential to be used as a good cementitious material. The results show that the compressive strength and low porosity of concrete improves substantially with partial replacement of Portland cement with fine bottom ash. Concrete mix cement containing 10-20% of fine bottom ash can be used to make cementitious materials. The use of finer bottom ash produces concrete mix with good strength and resistance to carbonation.

During the rice processing the possible situations of rice kernel cracking and breakage are commonly occurred and these consequences cause a low marketing price. According to this issue the real-time observation and together with the knowledge base of mechanical properties should be essentially helpful in detection of these defect observations. The objective of this work was established to study the mechanical stress-strain properties of rice kernels via our in-house pneumatic system design. We found that stress-strain of RD6 RD15 Phitsanulok 2 and Khao Dawk Mali 105 were greater than KhaoYipun DOAI with moisture content of 20% w.b. These results tentatively indicated the mechanical stress-strains occurred were from the difference of rice shapes. Moreover we could recognize that the characteristics of these various shapes significantly followed the scaling law of the relation between strain and time. We also found that the breaking force was different value for rice varieties. This parameter obtained can be such a high potential approach that can be used for further developing in the quantitative classification of rice varieties.

This is a survey research. Its objective was an attempt to analyze the problems and utilization of instructional innovations of lecturers at the Faculty of Industrial Education Rajamangala University of Technology Phra Nakhon. The sample group consists of 38 lecturers from four departments. The questionnaires were provided as the research tool to collect data. Statistical analysis was applied by using percentage mean standard deviation t-test and F-test technique. The research results were that the lecturers were different in gender age and educational background but problems in using instructional innovation were at the moderate level. The most internal important problematic factor was their attitude toward the utilization of innovation. The most external important problematic factor was lack of financial supporting on the production of instructional innovation. Lectures under the Civil Engineering and Mechanical Engineering Department had problems in difficulty of using instructional innovation more than those of the Electrical Engineering Department. Lecturers at the Faculty of Industrial Education need the training on Instructional Innovations.

This is a survey research. Its aim is an attempt to study and present the problems and Utilization of Instruction Innovations of Faculty of Industrial Education’s lecturesRajamangala University of Technology Phra Nakhon. The data collections were selected from population sampling of the Faculty of Industrial Education which consist of four departments with 38 lecture samples by using the purposive sampling. Research Methodology To study the problems and utilization of instruction innovations of the Faculty of Industrial Education’s lecture questionnaires were provided to collect data by using the average percentage value of standard deviation T-test and F-test technique. The following research results are : 1. The sexual differences of lectures has no any problems in using instruction innovation. 2. The different age levels of lecture have no problems in using instruction innovation. 3. For the lecture’s educational background there are no any problems in using instruction innovation. 4. Lectures in different departments of Faculty of Industrial Education have no any problems in using instruction innovation. 5. Lectures of Faculty of Industrial Education have a problem in using instruction innovation is at the moderate level. 6. According to the research results the most internal important problematic factor is the attitude’s lecture toward the necessary of instruction innovation. 7. The most external important problematic factor is the lack of financial supporting on production instruction innovation. 8. Lectures under the Civil Engineering and Mechanical Engineering department have problems in difficulty of using instruction innovation more than Electrical Engineering’s lecturers.
