This Research is to Study the Development of 6k White Gold Alloys for Jewelry Production. By Studying the Influence of 6k White Gold Alloys on Physical Properties for Jewelry Molding Process. Of 6k Gold Alloys at Various Compound Rates. The Results of the Experiments Show that the Chemical Composition of 6k White Gold Alloys is Slightly Different when Compared with the XRF (X-ray Fluorescence Spectrometers). Compare the pre and Post-Melting Quantities. The Result of the Compounding Test with the Color Level of 6k White Gold at the Compound Rate 25%Au+54%Ag+0%Cu+3%Zn+18%Pd The Lowest Color Level was L * = 82.14 a * = -0.16 b * = 7.71 and the Lowest Color Difference was 21.07. With other Ingredients It Shows that the Test Specimen of 6k White Gold has a Rather Greenish Color and is Slightly Yellowish Compared to the Blue Line that Approaches the Standard line. These Properties are the Physical Properties Required to Produce a 6k White Gold Jewelry Body.

This research aims to develop the natural-rubber floor tiles mixed with high fineness ethylene vinyl acetate plastic wastes (EVA plastics) from the factories. The study use natural-rubber STR 20 at 100 phr with various contents of EVA plastics (e.g. 0 5 10 20 40 and 80 phr) and then mixed with chemical substance at constant ratio include zinc oxide at 5 phr stearic acid at 2 phr mercaptobenzothiazole at 0.5 phr diphenyl guanidine at 0.2 phr and sulfur at 3 phr. The samples are ground by two-roll mill and formed by compression molding at 150 degree Celsius with 30x30x0.2 cm of dimension. The properties of the natural-rubber floor tiles are tested under ASTM standard. From the results it is found that the natural-rubber floor tiles mixed with 10 phr of EVA plastics is the suitable ratio for using as the rubber floor tiles in building. This ratio can increase the hardness tensile strength and wear resistant properties and decrease the density and thermal insulation properties when compare to the natural-rubber floor tiles without EVA plastic.

The research is to study the success factors in small and medium-sized enterprises in Nakhon Pathom. There are 2 points in objective: 1) to study characteristic of operation characteristic of entrepreneur characteristic of doing business and the success in an operation of small and medium-sized entrepreneurs. 2) to study the operation factor influencing the success of small and medium-sized enterprises. The sample size is 400 small and medium-sized entrepreneurs in Nakhon Pathom. In this research there are 3 independent variables including financial and accounting management production management and marketing mix. While dependent variable in the research is the success in doing business. Furthermore basic statistics and pearson correlation were applied in order to analyse all data. The results of this research are indicated that financial and accounting management have relation with the success at a significance level of 0.01. However when considering in each point of financial and accounting management it find out that financial planning is the factor that is more influential than accounting record at a significance level of 0.01. Meanwhile production management has relation with the success at a significance level of 0.01. Whereas it appears that the standardization is an influencing factor rather than quality and cost reduction respectively at a significance level of 0.01. In terms of marketing mix it presents that marketing mix also has relation with the success at significance level of 0.01. And when examining in each point of marketing mix product is more influential than promotion price and place at significance level of 0.01.

To do this project. Aims to study how to The equipment cloth spreading knock down.To save time in laying machine. To cloth spreading for a performance. Labor savingsThe sample used in the experiments The equipment cloth spreading knock down industrial clothing ready synchronization application path when they are limited and survey tool is divided into 4 steps 1 step is information. General of the respondents at the 2 as information about product format and The equipment cloth spreading knock down at about the 4 comments and suggestions by users. Use a percentage. Summary of experimental results that. Samples to The equipment cloth spreading knock down works as follow. Samples was mostly female. Are interested and would like a The equipment cloth spreading knock down. Which can reduce cost and labor savings. Increase the amount of crab cut fabric pieces and save time in laying machine is useful and appropriate can be made in the finished garment industry.
