Projects of this is intended to design a costume lady style streetwear has been inspired by the covers of the band Metallica Slipknot which is taken as a basic concept in design and application. development of clothing for women. By studying the characteristics of the mask and costume artists Metal Slipknot found that the structure of the mask is unique. A distinct and different away. Various techniques are used to create the mask in each weaving techniques such as stamping and cutting to mask a more attractive purchase. In the apparel group is a simple yet with a rock. The colors used are mostly black reflecting the dark. And conveyed out clearly. And a set that can actually wear. And can be applied to new forms to more modern too. The instrument used in this study is to analyze the pattern of costumes and masks. By analyzing four criteria 1.The theme of the design. Study patterns of design To guide the development of womens apparel in streetwear. 2.Colorful 3.Materials and techniques choice of materials to be used in the creation of jobs and the development to the costumes. 4. The benefits of living and appropriate. The study found that. The form of costumes masks and colorful techniques of artists METAL Group is adopting the structure of the clothing and decorative techniques applied to the mask from a costume designer streetwear style. Designed in a modern office. The focus on the style of dress. And the choice of materials The format of streetwear with a new and interesting. It also caused the picture.

This research aims to predict the thickness loss of parabolic forming by using hydromechanical deep drawing (HMD) process. The methodology used is the finite element method on the uncertainty of the mechanical properties for 1 mm thickness SPCC sheet metals. The properties consisted of three aspects: strength coefficient (K) strain hardening exponent (n-value) and plastic strain ratio for all three axis (r0 r45 and r90). Multiple simulations were completed by randomly selecting K n r0 r45 and r90 values following the distribution obtained from the uniaxial tensile test. The results would be analyzed by using the regression equation to create the equation to predict the thickness loss of the test pieces obtained from the formation process using the K n r0 r45 and r90 variables without the use of finite element method. This would results in a decrease in the simulation time. Based on 30 experiments of uniaxial tensile test it shows that the sheet metal properties are normally distributed. After that 60 cases of the five variables were randomly selected to simulate the formation by using the finite element method. Finally the results obtained from the aforementioned simulation is analyzed and generated into a regression equation. From the comparison between the value predicted from the regression equation and the result obtained from the formation process it can be seen that the regression equation can effectively predict the thickness loss when the five variables are under the same distribution properties. However the efficiency will decrease when the values of the five variables are beyond the distribution properties obtained from the experiment. In addition the uncertainty of mechanical properties of sheet metal in the simulation displays the chances of discovering test pieces with over 40% thickness loss. The simulation resulted in 5 damaged test pieces accounting for 8.33% of the total process.

This study aims to development of production process of hard metal by tungsten carbide powder with the particle sized of 0.1 - 0.35 µm. This carbide powder were made of recycling cemented carbide tool scraps so it is mixed with Ta = 2.82 % Mo = 0.45 % Nb = 1.22 % Ti = 4.56 % Zr = 0.37 % The shape of the carbide powder are roughly round due to ball milling for 300 hours. It was mixing cobalt 10 % and Paraffin wax 2 % which is found the work piece that running through the process of sintering with a temperature of 1400 °c and 1430 °c have the hardness of 1368.5 and 1346.3 HV respectively. In one hour of holding time process the work piece with 1430 °c of the sintering causes less wear. After the test of turning operation it can be concluded that the tungsten carbide cutting tool provides the equivalent quality as a standard cutting tool.

The cobalt catalysts (cobalt content by weight: 7% 10% and 15%) and cobalt-nickel bimetallic catalysts (cobalt-nickel content by weight: 3.5%-3.5% 5%-5% and 7%-7%) were studied in dry reforming of methane for hydrogen and syngas production. All catalysts were synthesized by the wetness impregnation method. The dry reforming of methane was carried out at 700oC atmosphere pressure using a mixture; CH4 and CO2 in ratio 1:1. The result showed that the good activity and stability depend on metal content in catalysts and the combined 2 metals as bimetallic catalysts. The optimum amounts of catalysts are 10wt% Co for mono-metallic catalysts 75%CH4 and 75%CO2 conversion and 7wt% Ni-7wt% Co for bimetallic catalysts 87%CH4 and 89%CO2 conversion.

This research work aims to analyse of metals in thai tradition medicines using Inductively Coupled Plasma–Optical Emission Spectrometry (ICP-OES). The sample groups were divided into four catagories which were Snuff balsam gentian violet and drug pickled liquor. Six metals Aluminium (Al) Cadmium (Cd) Chromium (Cr) Copper (Cu) Magnesium (Mn) and Lead (Pb) were studied. In Snuff the amount of Al was in the range of ND-0.017 ppm the amount of Cd was in the range of ND-0.017 ppm the amount of Cr was in the range of 0.041-0.173 ppm the amount of Cu was in the range of ND-0.244 ppm Moreover Mn content was in the range of 0.633-2.384 ppm. In the case of balsam the amount of Al was in the range of 0-0.575 ppm the amount of Cd was in the range of ND-0.004 ppm the amount of Cr was in the range of 0.025-0.570 ppm the amount of Mn was in the range of 0.460-0.754 ppm whilst none of Cu and Pb was detected. In the case of gentian violet the amount of Cr was in the range of 0.033-0.063 ppm the amount of Mn was in the range of 0.165-0.543 ppm whilst none of Al Cd Cu and Pb was detected. In the case of medicine pickled the amount of Cr was in the range of ND-0.058 ppm the amount of Mn was in the range of ND-0.264 ppm the amount of Ni was in the range of 0-0.034 ppm no metals Al Cd Cu and Pb was observed. The detected metals in thai tradition medicines have the contamination value under the optimization scale for consumable under WHO. It show that some metals were retained in thai tradition medicines and the contamination level of metals in were acceptable.
