A promising composite of zinc ferrite (ZnFe2O4) and bioactive hydroxyapatite (Ca10(PO4)6(OH)2 ;HAp) has expected to potential for future bone reinforcing formation. In present study zinc ferrite and hydroxyapatite composite was prepared by solid state reaction route for easier control of structural and magnetic characteristics and with low cost. Hydroxyapatite powder was synthesized by precipitation method from chicken eggshell. Mixed powders with varying ZnFe2O4/HAp weight ratios from 2-10 wt% were milled together and uniaxially pressed and then sintered at 1200 oC for 3 hours. The XRD results showing no other phases of composite with only HAp and ZnFe2O4 phases were identified indicating high stability of HAp property. Phase fractions of ZnFe2O4 were found to increase from 10.8 to 18.73 wt% with increasing content of ZnFe2O4. FT-IR results of ZnFe2O4/HAp composite were only revealed vibration bands of standard HAp phase. This may due to the overlapping of the ZnFe2O4 vibrational bands with HAp bands. However their intense variations observed in HAp vibrational bands indicated the interaction between ZnFe2O4 and HAp. The surface morphology of these ZnFe2O4/HAp composite exhibited primary grain in nano scale with enhanced pore structure and Interconnectivity when ZnFe2O4 weight ratios increased; indicating high surface area for cell attachment and better good cell growth and differentiation. The higher saturation magnetization as well as higher super paramagnetic behavior could be easily altered by increasing ZnFe2O4 content in the composite.

The purposes of the study were to investigate the level of each aspect of information technology use on the internet; and to compare the level of the Internet use of personnel working at Royal Irrigation Department (Samsen branch). 364 persons were the sample selected by Yamane sample size determination. The questionnaire was administered with as the instrument for collecting data which were analyzed by the frequency distribution percentage distribution standard deviation t-test and One-Way ANOVA. The results revealed that investigate the level of information technology use on the internet of personnel working at Royal Irrigation Department (Samsen branch) was relatively high in terms of the educational use. As for the purposes of the use for communication use the use according to the workplace policy and the use for entertainment were average; however in terms of the commercial use the result was quite low. Moreover different genders and educational levels revealed similar internet information technology use; opposite from age personal factors which resulted in 0.05 statistical difference.

The objective of this research is to investigate microstructure and mechanical properties of brass welded by diffusion welding process. The diffusion welding (DW) of brass welded over lap joints bonding parameters were pressure at temperature 500 650 and 800 0C contact pressure of 12 MPa and holding time for 60 minutes respectively. The microstructure mechanical properties and behaviour during bonding were investigated. The results show that in weld zone (Bond Line) diffusion of atom the brass significantly. The mechanical properties after diffusion welding process increased higher temperature

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 %.

This Study aims to 1) study the clothing purchasing behaviors via internet medium of the teenagers and 2) study the marketing strategies in the form of internet medium for teenager clothing businesses. This is only to study the purchasing behaviors via internet medium of the 400 teenagers via facebook website. The data were collected by using sets of questionnaire and the software packages were used in data analysis. According to the results of the study of the clothing purchasing behaviors via internet medium of the teenagers most of the sample groups were female at the rate of 72.8% being aged 19-21 years at the rate of 50.8% residing in the Bangkok Metropolitan Region at the rate of 47.8% studying at the bachelor’s degree at the rate of 63.8% most of whom were students at the rate of 49.3% having income in the amount of 10001-15000 Baht at the rate of 37.8% most of whom purchased casual wears at the rate of 39.7% fashion clothes at the rate of 42.8% with the brand influencing the purchase at the rate of 26.3% each piece of the clothing was in the amount of 501-1000 Baht at the rate of 23.5% purchasing 1 time per month at the rate of 47.8% purchasing 2 pieces per time at the rate of 36.2% the sample groups ordered clothing from abroad at the rate of 55.5% paying via bank account at the rate of 54% purchasing the clothing as ready for delivery at the rate of 97.5% and the factor on marketing strategies had the average score in the high level at the rate of 3.86%.
