This Research is a Development of 8k White Gold low Alloy Metal Components for Jewelry Pieces. By Study and Analyze the Influence of Silver Alloy Gold Alloy Bronze Alloy Zinc Alloy and Tin Alloy. Which Affect Microstructure and Mechanical Properties. (The Different of Color Scales) And Resistance Behavior of Lowered 8k White Gold Alloy in Varies Ratio. The Results Showed that Tests and Analysis to Find the Quantities of Elements has found out that Chemical Components of 8k White Gold Low Alloy Metal had a Little Different Quantities when Compared Between Before and After Centrifugal Casting Process. The Tests and Analysis Results of Mechanical Properties of Test Pieces Showed that the Hardness and Tensile Strength of 8k White Gold Low Alloy Metal with Mixture of 33.33%Au+50.67%Ag+10%Cu+5%Zn+1%Sn had Minimum Ultimate Tensile Strength Equal 0.54 kN/mm2 Minimum Elongation Percentage of 55% and Maximum Hardness of 137.0 HV. The Test Results also Show that the Mechanical Properties of the Material are Brittle Material. When Perform a Forming Process the Pieces will be Easily Broken which was Meant that the Forming Process would be Difficult. But The Color Level of the Test Pieces at this Composite Ratio had the Best Metal Color Level. The Brightness L * = 74.87 was a * = -0.89 b * = 13.74 and the Value of ΔE with the Lowest Color Difference Level of 1.35. Compared to other Varies Ratio. It Showed that 8k White Gold Low Alloy Metal Test Pieces were Very Green and Came out Slightly Yellow Compared to the Blue Line that Approached the Standard Line. These Properties were the Physical Properties Required in 8k White Gold Low Alloy Metal Jewelry Pieces Production. Also there were the Results of 8k White Gold Low Alloy Metal in Two Formulas 8k 33.33%Au+50.67%Ag +8%Cu+7%Zn+1%Sn 33.33%Au+50.67%Ag+8%Cu+8%Zn+0%Sn. These Formulas had Tensile Strength in the Range of 1.10 0.60 kN /mm2 Elongation Percentage in the Range of 70 61% and Hardness of 115.6 123.3HV Respectively. The Results of the Mechanical Properties Test of the Test Pieces Showed that 8k White Gold Low Alloy Metal 33.33% Au+50.67%Ag+8%Cu+7%Zn+1%Sn has Similar Tensile Strength but Maximum Elongation Percentage of 70% and Minimum Hardness of 115.6HV. Which was Suitable for Forming Because of good Ductility and Stretchness Properties (Ductile Material). Forming would be Easy. These were Good Mechanical Properties for Forming Precious Metals.

Currently the automotive industry plays an important role on the economic growth in Thailand. As the same time the waste of automotive parts has increased as well. As a results the automotive parts made from three different natural fiber parts was studied consisting of hyacinths sugarcane and pineapple leaf fiber. By of 50 x 250 x 20 mm of mold dimension the specimens were produced under 700 W of heating stick and measured temperature by a K type of thermometer. There were 3 same proportion specimens made from: 1) sugar cane fiber: husk: latex adhesive 2) water hyacinth fiber: husk: latex adhesive 3) pineapple fiber: husk: latex adhesive in the ratio of 25:25:50 by weight which were formed under temperature between 100GC and 105°C at 5 MPa of pressure and leading to find out the bending moment ability. The test results show that the specimen made from sugar cane fiber has the highest value 5482.5 Nand 4061.11 N/mm2 of bending moment and bending stress respectively. It was more than specimen made of water hyacinth 29.84 % and pineapple fiber 65.01 %.

The objectives of this research are to propose an efficient and proper model that fits the cassava and rubber yields data. A generalized estimating equation (GEE) and a linear mixed model (LMM) with spatial correlation following the conditional autoregressive model (CAR) were adopted. The dependent variables are the cassava and rubber yields collected each month in every province of Thailand. The factors considered are rainfall averaged temperatures and regions. The results from GEE and LMM show that the factors influencing on the cassava and rubber yields are rainfall averaged temperature and region. Both GEE and LMM fit the correlated data. The GEE is used to explain the influence of factors on the yields in all provinces while the LMM is used to explain the influence of factors on the yields in each province.

The research is study motives the affect participation in quality assurance personal of Faculty of Engineering Rajamangala University of Technology Phra Nakhon from example group of 182 people which classified by sex ages position educational degree field of work and working life. This research is used themethod is collecting data by question tool themethod is questionare tool fo collected data that could be two categorized include knowledge skills and attitudes. The questionnaire is five rating scales that analyze the result by frequency percent average the average of standard deviation and T-test independent by using one way ANOVA. The results were as follows : From one hundred percent of the personnel of Faculty of Engineering Rajamangala University of Technology Phra Nakhon whom 63.70 persent classified by the educational field and 36.30% support line are ready to enter into Asean community which could be seen average in whole picture. After considering in three aspects the result appeared that knowledge and skills of personnel are also average. However the attitude of personnel was considered in a high level. Hypothetic test result was found that there was no difference among the personnel with difference sex ages educational degree field of work and working life in their readiness in entering Asean Community. position
