Nowadays an automotive industry steadily has been growing and playing a major role on economy development for many years. The crash box is one of the most important parts for safety but it was found that the crash boxes manufactured domestically are not met international standard requirements. This is due to process and material limitation. This process for automotive safety test requires high budget and there is unclear approach for specific test. Therefore a study of crash boxes referred to energy absorption project was conducted as the alternative materials for product. Consequently this project was aimed to design and test crash boxes which made from the diversity of the alternative materials such as aluminum aluminum reinforced by foam resin reinforced by fiberglass resin reinforced by water hyacinth and resin reinforced by water hyacinth and husk. In addition it was also emphasized in studying energy absorption behavior and physical deformation of crash boxes after dynamic and static energy being applied. The experimental works were applied for these tests in partly referenced to US NCAP and ECE R29 standard for automobile collision test. Testing all types of crash boxes indicated that the aluminum reinforced by foam type was able to absorb energy at 189 MJ/m3. It is higher than resin reinforced by water hyacinth and husk at 1 MJ/m3 as 188 times. Furthermore the comparison of the energy absorption (per unit volume) between the aluminum reinforced by foam type and the steel type from the previous project equivalent 20 MJ/m3 found that it is 8.45 times of difference. While the front impact test was not successful because the size of crash boxes was not suitable for the energy volume. It was a cause for non-available calculation of energy absorption value.

This paper describes an aluminum casting jewelry manufacturing because of the current manufacturing costs are higher. Material or metal that is commonly used to cast jewelry is silver which aluminum Alternatives to metal. Melting is There is a close color and surface finish can be beautiful. But aluminum is a material that is cheap has studied and tested. Replacement aluminum casting body jewelry. The temperature in the baking mold before casting to test all five temperatures are 550 500 450 400 350 degrees Celsius then casting body jewelry in the next stage of the research process casting jewelry with the. aluminum to Experimental temperatures used in baking mold casting plaster for the mold temperature of 400 is appropriate. Best of casting jewelry with aluminum. The results showed that there is minimal waste and a 102 pieces of 48 pieces and has a smooth surface. A similar performance to the other materials available. Similar properties

The objectives of this research were to study the reduction of organic compounds by the biological action substance of the effluents from palm oil mil to produce singe cell protein. The wastewater taken from the third pond of the wastewater treatment system which was already used for biogas production was found to have pH 6.5. The organic matter like COD (3679 mg/L) Oil& grease (133 mg/L) as well as the total solids and the minerals were much lower than those of the decanter effluent. The reduction of organic compounds by using the biological action by Candida tropicalis TISTR 5146 5045 and C. lipolytica TISTR 5151 were studied. The results indicated that C. tropicalis TISTR 5146 which was cultivated in palm oil mill at initial pH 5.5 and diluted with water to the ratios of 1:5 at agitation on the shaker of 150 rpm at room temperature gave the highest yield of biomass of 2.52 g/L and COD reduction of 94.38 % after 3 days of cultivation. The optimal condition for C. tropicalis TISTR 5146 cultivation was that the ratio of palm oil mill effluent to diluted water was 1:5 containing 10 g/l glucose and 10 g/l yeast extract at initial medium pH 5.5 in the shaking flask of 150 rpm at room temperature. The highest biomass obtained was 12.53 g/L while the cell consisted of protein and fat for 43.12 % and 0.34 % respectively.

Thai Local Herbs Snack Product (TLHSP) is very popular and has increase tendency the target group in worldwide such as children teenager and adult which live in metropolis. The aim was 1.) to study the formular and condition to produce TLHSP by extruder machine 2.) to study the type and quantity of Thai Local Herbs which was added 3.) to study the shelf-life and type of package to keep TLHSP. The study used CRD to design the method and has a stable variable is 1% CaCo3and varies 2 variables are the ratio between a speed of single screw at 3 levels such as 250 300 and 350 rpm and moisture content of raw material at 3 levels such as 15 17.5 and 20. And this research study about the level of grinded sugar (GS) at 3 levels such as 0 3 and 6 g. which at 3 g. the TLHSP had well scores of 7 to 8 (like moderately to like very much; used 9 Points Hedonic Scale method for the sensory test) the characteristic for color was 7.37+ 0.01 texture in crisp was 7.33+ 0.01 and overall acceptance was 7.70+ 0.01. Especially odor was 7.63+ 0.01 and taste was 7.38+ 0.03 there were significant differences (p<0.05) with 0 and 6% grinded sugar. TLHSP was well accepted by consumers with 88.00% (By the Central Location Test for questionnaire paper survey). Almost 70% were female 88% had 18-27 years-old 81% were student and 56% hadincome cash < 5001 baht/ months. This study used the extrusion technology to produceTLHSP which the fixed specification fallow as; a speed of single screw was 300 rpm Barrel temperature was 134-165 ˚C 380 Volt 85 amp a diameter in front of machine was 2 mm. a speed of blade 95 rpm and had 2 pieces. And the capacity was 14.4 kg/hr. Therefore aw0.34±0.02 Lightness 60.41 ± 0.16 %extended ratio1.69±0.01 %bulk density 0.15± 0.001. Chemical Properties for %moisture6.60±0.16 %protein 7.88±0.16
