“Technology transfer to return productive citizen into the society” is a project of the technology clinic Rajamangala University of Technology Pra Nakhon Chumpornkhet-udomsak. The project objectives are job training for female prisoners and transferring good technological techniques to the community. The target group is female prisoners from the Central Prison and Thonburi Prison. The project is a vocational training workshop. It is found that 100% of trainees are satisfied with the program at a high level and businessmen are interested in ordering the prisoners’ handicraft products to sell in the country and export to other countries.

This paper presents a study on the strength and corrosion resistance of mortars made with binary blends of ordinary Portland cement (OPC) and ground rice husk ash (RHA) or ground palm oil fuel ash (POA). The mortar mixtures were made with Portland cement Type I containing 0-40% RHA and POA. RHA and POA with 1-3% by weight retained on a sieve No.325 were used. The water to binder ratio was kept constant at 0.5 and the flow of mortar was maintained at 110±5% with the aid of superplasticizer (SP). Scanning electron microscopy (SEM) was used for analysis. The compressive strength chloride penetration and corrosion resistance of the mortar were determined. The results show that strength as well as the resistance of mortar to chloride and corrosion can be improved by blending with RHA and POA. Thus RHA and POA have a high potential to be used as a good pozzolanic material.

The research analyzes benefit cost and break even point including sensitivity of making biodiesel production factory from palm fatty acid. Biodiesel production system of Thailand Institute of Scientific and Technological Research (TISTR) is used for this study. It is found the present net value has been a deficit of 27024966 baht. The sensitivity of the project has been analyzed by increasing selling price of biodiesel of 5% and 7.5% but reducing material price of 10% and 20%. It is found the present net value still has been deficient. The project will payback at 5th 8th and 10th year be with selling price of biodiesel. is about 31.71 baht per litre. Therefore the cost of palm fatty acid should lower than 2.89 3.05 and 3.82 baht per kilogram. If selling price of biodiesel about 33.30 baht per litre the cost of palm fatty acid should be lower than 4.65 4.82 and 5.58 baht per kilogram. respectively.

This paper presents a study on the strength and porosity of mortars made with binary blends of ordinary Portland cement type I (OPC) sand and ground rice husk ash (RHA) or ground palm oil fuel ash (POA). The mortar mixtures were made with Portland cement Type I containing 0-40% RHA and POA. The water to binder ratio was kept constant at 0.5 and the flow of mortar was maintained at 110 +/- 5% with the aid of superplasticizer (SP). X-ray diffraction (XRD) and scanning electron microscopy (SEM) were used on materials. Compressive strength and porosity of the mortar were determined. The XRD pattern confirmed that POA and RHA were mainly amorphous silica. The use of RHA and POA produced waste ash with relatively high strength. The porosity of mortar containing RHA and POA decreased with the low replacement level of up to 20% of pozzolanic but increased with the 40% replacement level. RHA and POA have a high potential to be used as a good pozzolanic material in concrete work.

The objective of this survey research was to study the opinion of people in Samutsakhon Municipality Samutsakhon province concerning the construction of on-ground pipe-water production system. The results of this survey research were as follows : the opinion and requirement of people in Samutsakhon concerning the construction of on-ground pipe-water production system were at high level. The perception of problems concerning the construction of pipe-water production system was not relative to the opinion of people in However the perception of information in constructing pipe-water production system and the participatory responsibilities in service of pipe-water production system were positively and significantly relative to the opinion of people at the level of .05
