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.

In general the measured resistance with a digital multimeter. Users tend to be measured and then displayed on the screen to the user regardless of the value that is accurate or not. The value displayed on screen digital multimeter may be incorrect. As a result from wires access point measurement and other factor that affect to the value of measurement. Thus the study of factors that affect the measurement to get the accurate and more precise and also can be used in the operations. According to international standard quality system requirements for ISO are clearly on the meter or the measuring device must be calibrated and in the certificate specifies the gain calibration and the uncertainty of measurement. Therefore it is necessary to evaluate the uncertainty of measurement to comply with the standard splash. This thesis presents a study of the effect to the measurement resistance in 0.01 ohm to 100 mega-ohm by direct measurement for 2wire & 4wire Loading effect Using different kinds of conductors Thermal EMF and the stability of the resistor. Include the statistical analysis was used to estimate the uncertainty. From this study can be applied to measure the resistance in a variety of accurately and precisely.

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.

Social networking is a popular medium for the business of selling female clothing and has been growing steadily. This is because of ease and availability of access faster communication and lower cost in comparison to competing market media strategies. This study investigates the influence of integrated marketing communications (IMC) on female decision making in social online clothing purchase. The research involves quantitative method by use of questionnaire as a tool in collecting information. The population for this study comprises females who live in Bangkok and use online social networking services. Quota sampling is used to select for a sample size of 445 subjects. The results show that most in the sample group deciding to purchase clothes online with an overview of IMC tools (advertising public relations promotion and direct marketing) are in the moderate range (43.82%). In addition Eta ( ) correlation ratio indicates strong nonlinear relationship between clothing purchase and the IMC tools except for advertising which has a weak positive relationship (0.165). Multiple regression analysis results show that marital status age level of education revenue time using the Internet and times to view products through online social network all have effect on clothing purchase. The sample group outcome suggests that entrepreneurs should pay attention to warranty information on products and prices security of financial transactions and contact with manufacturers in order to encourage consumer online purchasing.
