Development of Additional Skill Toy from dust mite defending Fabric.
The objective of this research is to develop the additional skill toy from dust mite defending fabric. There are categories into three products : 1) Non decorated dust mite defending Fabric 2) Printed cartoon of dust mite defending Fabric 3) Covered colorful cloth of dust mite defending fabric. It can be divided into 3 patterns of this product : 1) the geometric style (triangle square hexagon) the ring toss style and the jigsaw style. The findings of this research were as follow : In term of children between 2-6 year old they like the covered colorful cloth of dust mite defending Fabric and they choose mostly the ring toss style followed by the printed cartoon of dust mite defending Fabric and the ring toss style. In term of parents group have never seen this product and they think that the using material is suitable. Besides they prefer the geometric style in vibrant colors for decorating the printing method and covered colorful cloth of dust mite defending fabric as well as the choosing product should realize the important health. Moreover they prefer very much the decoration of printed cartoon of dust mite defending fabric in the ring toss. In case of product they prefer the geometric about size style and suitability. In term of general interested people group have never seen this product and they think that the using material is suitable. Besides they prefer the jigsaw style in vibrant colors for decorating the printing method. Moreover they prefer the decoration of covered colorful cloth of dust mite defending fabric in the geometric style. In case of product they prefer the geometric about size style and suitability..
Design and Product Development Ceramics Using for Making Wall of Energy Conservation Building
This research aims to study and develop ceramics material using in the wall construction which can be used to proof the heat and water reduce absorbed humidity in the building. The product can save the energy especially the building which is set the air conditioning. The experiment found that the proportion of clay body can be developed and the result of thermal conductivity (K- value) was 0.111 W/ m. /K the permeability was 7 percent the glaze can be used to proof water. The product was compared to three kinds of construction materials which are brick concrete masonry unit and autoclaved aerated concrete found that K- value and permeability were lower. Moreover it can proof water and save more energy for the air conditioning building.
The Development of a Computer Assisted Instruction Package with Tutorial Through E-Learning on Computer Technology Curriculum
The purposes of the research were to design and develop a computer assisted instruction package with tutorial through e-learning on computer technology curriculum and to find out efficiency effectiveness and learners’ satisfaction towards the package. The research tools are 1) the Computer Instruction Package on Database Management System Subject 2) Achievement evaluations 3) Quality assessment and evaluation form for multimedia software and 4) Questionnaire of learners’ satisfaction. The research results reveals that the efficiency of the Computer Instruction Package was at 82.50/82.56 corresponding with 80/80 criteria. The analysis of pre-test and post-test scores finds that the effectiveness after the process (Epost) was at 82.56 which was higher than one tested before the process (Epre) which was at 14.62. Therefore the Computer Instruction Package on Program Design and Development could increase the students learning effectiveness up to 67.94 corresponding with 60 criteria. The Mean of satisfaction of the sampling groups was rather at a high level (4.28). It could be concluded that the Computer Assisted Instruction Package with tutorial through e-learning on computer technology curriculum had the efficiency that could used for self study.
Mechanical Properties of Silica-Based Geopolymer Composites Cured at Ambient Conditions in Accordance with Size-Independent Method
In this paper silica-based geopolymer matrix reinforced composites containing approximately 35 50 or 55 wt.% of carbon (HTS 5631 1600tex 24K TohoTenax) advanced basalt (BCF13-2520tex KV12 Int Basaltex) or electrical grade glass (E-glass: E2400P192 Saint-Gobain Vetrotex) roving fibers respectively were synthesized and fabricated at ambient conditions. The flexural properties of the resulting composites which are high toughness: the shear stress plays here a greater role in compared with other ceramic matrix composites were determined on a universal testing machine under three-point bending mode in accordance with novel size-independent method which based on testing specimens at different scale of sample height (H) to span length (L) ratios; The basic principles of the new size-independent approach are presented as well. Microstructures of composites were analyzed by means of scanning electron microscope (SEM) on perpendicular sections the images show the adhesion between the fibers and geopolymer matrix are very good and micro-cracks on both cross-sections and surfaces of geocomposites are determined as inborn defects of inorganic matrix composites.
Temperature Reduction in Hydroponic Planting System Using Heat Pipe
This paper presents an establishment of a mathematical model to determine the optimal size of heat pipe (thermosyphon) heat exchanger for reduce the inlet air temperature in evaporative cooling system of greenhouse. The condition of a mathematical model is the total length of heat pipe is 1.5 m. A mathematical model will determine the optimal value of evaporator section and condenser section. The range of evaporator length is 0.5 – 1.4 m with an increment of 0.1 m and condenser length is in range of 0.1 – 1.0 m with an increment of 0.1 m. The inlet air temperature in evaporative cooling of greenhouse is depend on ambient temperature about 35 degree Celsius. While the cooling water temperature is 20 degree Celsius. Evaporative pad of evaporative cooling system is 2 m in width and 7 m in length. From the conditions above the optimize results from a mathematical model are as follows: evaporator section length is 0.9 m and condenser section length is 0.6 m moreover it was shown that investment net saving and maximum heat rate are 79.83 Thousand Baht 0.552 Million Baht and 15.6 kW respectively.
