The objectives of this research are to develop the knock down house to create the knowledge to test the properties to construction the prototype and to transfer the technology of easy transport knock down house for sufferer. The load and resistance factor design (LRFD) method was used to design the structure. From the design and testing the easy transport knock down house for sufferer is the square shape building with gable roof. The building size 4.00 x 4.00 square meters and height 2.40 meters which has 16.00 square meters of usable area and 1.20 meters of gable roof height. This knock down house can separate the usable area into 2 parts include bedroom and toilet. The cost of material is 125000 Baht per unit or 7812.5 Baht per square meter. The 6 wheel truck can transport this knock down house. The safety factor (S.F.) of this knock down house equal to 1.86. Moreover the knowledge can register the copyright names “The drawing of easy transport knock down house for sufferer” and draft the research paper names “The easy transport knock down house for sufferer” that are the way to transfer technology to target group.

Exciting permanent-magnetic-field affecting to the bean sprout growing
Exciting permanent-magnetic-field affecting to the bean sprout growing

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 %.

In this reseach propose developed method for reduction of corrosion of reinforcement in concrete using electrical electron theory (artificial anode). That is electrochemical reaction in the concrete with current electron of electricity designing interchanges galvanized steel by install zinc anode. Zinc is one of the first materials to be used in ion exchange processes easily. Properties of Electrica will include the anode (Anode) and specemen concrete is negative (Cathode). The system is effects to results; reduce superior resistance corrosion in reinforcing steel in concrete more the better then traditional. The relationship of the electric reduction in the reinforcement concrete depen on capable of zinc electricchamical reduction in the steel of reinforced concrete. Zinc anade size is use to install concrete corrosion rate in steel reinforcement is direct variation of size.

Mechanical properties of concrete mixed with reused ceramic tiles reinforced with steel fiber from milling processed
Mechanical properties of concrete mixed with reused ceramic tiles reinforced with steel fiber from milling processed

This research study the mechanical properties of concrete mixed with reused ceramic tiles reinforced with steel fiber from milling processed. The compressive strength of all concretes were designed at 300 ksc at 28 days and control slump in the range of 10 ? 2.5 cm. The steel fiber from milling processed was reinforced at 0.50 1.00 and 1.50 by the weight of cement content. The compressive strength Flexural and tensile splitting for all concrete samples were tested compare with control concrete which it as concrete mixed with reused ceramic tiles not reinforced with steel fiber. The results shown that the reinforcing with steel fiber from milling process at 0.5 and 1.0% was affect to the higher compressive strength than control concrete of 2 and 7% but increasing steel fiber at 1.5% was affect to lower compressive strength than control concrete of 6%. Concrete mixed with steel fiber from milling processed at 1.0% have higher splitting tensile strength than control concrete of 16% while concrete mixed with steel fiber at 0.5 and 1.5% have splitting tensile strength equal with control concrete. The flexural strength of these concretes have higher more than control concrete about 9 17 and 11% for reinforcing with steel fiber at 0.50 1.00 and 1.50 respectively. In addition the water permeability of concretes were increased when the steel fiber were reinforced increases too.
