This research then has two main objectives. The first objective is to fabrication of bioactive glass ceramics containing BaFe12O19 (BF) crystals has been carried out for the application in hyperthermia treatment. The BaFe12O19 powder was firstly prepared and subsequently mixed with the non-silicate P2O5-CaO-Na2O bioactive glass with various BF concentrations. After that the glass ceramics were produced via a sintering method at 600◦C and their crystal phases were examined by XRD and in vitro test was carried out by soaking in simulated body fluid. Remanence and saturation magnetization and coercivity were deduced from magnetic measurement. It was found that the samples exhibited magnetic behavior which is similar to hard magnetic materials. Our second objective is the effects of sintering temperatures on the physical and bioactivity of SrFe12O19 (SF)-P2O5-CaO-Na2O bioglass ceramics were investigated. XRD results confirmed the existence of the strontium ferrite and calcium phosphate phases. SEM images showed that grain size and hardness were related to density and liquid phase present in the samples. A maximum coercivity value of 3138 Oe was obtained for the bioglass ceramic sintered at 600 ºC. The remanence (Mr) and saturation magnetization (Ms) of the bioglass ceramic sintered at 500 ºC possess the maximum value of 6.35 and 10.64 emu/g respectively. Moreover the apatite was formed on the surface layers of the bioglass ceramics confirming their biocompatibility

This research is the study and development of the information system for managing resources and database by focusing on the workload academic teacher (WAT) systems for the teachers worked on the Faculty of Science and Technology Rajamangala University of Technology Phra Nakhon. The main objective was to develop the WAT systems based on the web-based application (web application) and to evaluate the effectiveness and to assess user satisfaction with WAT systems. The WAT systems were also performed based on the system development life cycle (SDLC) and requirements gathering analysis of existing systems with the paper-based managements to new systems for use in the electronic managements. The evaluation of efficiency of the WAT systems was performed by the information technologists for the functionality of WAT systems resulting in the average satisfaction score is 4.36 with the standard deviation of 0.54. As the same experts the satisfaction of usability such as login procedure choosing the workload issues to easy document upload and filledforms performances etc. resulting in the average satisfaction score is 4.29 with the standard deviation of 0.55. These results provided the high level of experts’ satisfaction. After improving the WAT systems the functionality and the usability of systems were evaluated by usage teachers. It was found that the average satisfaction score of the functionality is 4.21 with the standard deviation of 0.67 and the usability is 3.56 with the standard deviation of 0.96 (n=15). It can be implied that the WAT systems can be applied to practical and responsive to the needs of users.

This research study the effect of pozzolanic materials on light weight concrete by replacement cement with fly ash and Meta kaolin which affect the properties of concrete by using pumics aggregate. Coarse in aerated concrete and consider mechanical properties. Aerated concrete replacement cement by fly ash 20% 35% and 50% respectively and meta-kaolin is replaced. From the results it was found that the compressive strength of light weight concrete at 28 days w/b = 0.55 was higher than that of every 14 days of cement and cement cement replacement by fly ash 50% highest value compressive strength. More than all the ingredients replaced with fly ash and Meta kaolin. When considering the flexural strength of replacement cement with 10% by Meta kaolin the maximum flexural strength of 80 ksc was higher than that of control concrete and all other ingradient. Experimental tensile strength at 28 days result found that replacement cement by fly ash at 35% gave the highest tensile strength of 28 ksc and gave higher tensile strength than all other ingradient. From the impact strength test at age 28 days it was found that the replacement cement 35% by fly ash gave the highest impact strength of 92.00 joule than the 20% and 50% respectively and higher impact strength than that of all kaolin. Except for control concrete.

This research study to the effect of pozzolanic materials by replacement cement by fly ash and Meta kaolin which affect the mechanical and physical properties of concrete. According to Standard test such as Compressive strength flexural strength and impact strength. The replacement cement by fly ash was 15% 30% and 45% respectively and replacement cement by meta-kaolin was 10% 15% and 20% respectively. The results showed that the compressive strength of concrete at 28 days. When considered ratio w/b = 0.40 was higher than w/b = 0.45 all ingredient. The replacement cement by fly ash was the most effective. 10% (375 ksc) 15% (362 ksc) and 20% (354 ksc) respectively. The replacement cement by meta-kaolin gave the highest flexural strength of 41 ksc higher than control mixed concrete and all other ingredient. At the age of 28 days The replacement cement by meta-kaolin was 10 percent result to the highest impact strength was 11 joule which was close to that of fly ash by 30 percent give value was 110 joules and more than replacement cement by meta-kaolin was 15% (100 joule) and 20% (95 joule). It can be concluded that the increase in meta-kaolin content result to compressive strength will reduce flexural strength and impact strength. As the amount of fly ash increased the compressive strength increased. flexural strength and impact strength Increased value.

At present the electrical power system has growth and more complicate. Because of the development of the economics and society. An increasing the demand of power transmission line system would be resulted in the stability and reliability. The Flexible AC Transmission System devices: (FACTS) is the equipment which can control the flow of real power. In addition it can gladly encourage the stability and reliability of the power transmission line system. This research proposed the impact of placing power electronics device to increase stability and reliability of power system in order to study the impact of Flexible AC Transmission System devices: (FACTS) devices for the resulting to stability of power system. UPFC devices model which consisted of Static Synchronous Compensator and Static Synchronous Series Compensator that worked as independent voltage source for technique to proposed control the flow of real power and reactive power as well as voltage bus in power system. Testing Simulation power flow control of 5 buses by placing unified power flow control indicated the effective compensation of real power and reactive power in power system.
