The experiment on using of different levels fishes condensate as feed contain in climbing perch (Anabas testudineus Bloch). To study on growth rate (SGR) feed conversion ratio (FCR) protein efficiency ratio (PER) and survival rate of climbing perch. The diets contained 40% protein and 3200 Kcal/Kg (DE) in all formulas with varying levels ; 0 25 50 and 75% of fishes condensate replacement of fish meal respectively and compared with pellet feed (formula 5). The diets were given for 10 weeks to fish which the initial average weight were 4.43+0.14 g. The result showed that the SGR FCR PER and survival rate of climbing perch was 25 percentage of fishes condensate (formula 2) gave highest growth performance as SGR 0.72+0.16 (%/day) and PER 1.12+0.22 were significantly different (p<0.05) with 0 75 and 50% respectively but not significantly different from the control feed (formula 5). All of the feed formulas showed no effect on survival rate (p>0.05).

Combining ability test of eight F5 gherkin lines from 5 generations in selected pedigree method 28 direct and 28 reciprocal crosses was performed. The objective of this study was to selected high general combining ability line and high specific combining ability hybrid for commercial variety. The experiment was designed in RCB with 2 blocks. The trial was planted during July to September 2012 at Lampang Agricultural Research and Training Centre Lampang province. Data were analyzed using Griffing method 1 with fixed treatment effect. The results were significant between varietal in all traits except yield and fruit per plant. General combining ability (GCA) was significant in all traits. Specific combining ability (SCA) was significant in all traits except yield and fruit per plant. Significance was also found in reciprocal effect in all traits except the width of fruit. For the yield of lines P1 P3 P2 P5 and P8 expressed high GCA and six hybrids were P5 / P3 P5 / P2 P1 / P5 P6 / P2 P3 / P2 and P6 / P8 had high SCA.

The objectives of this study are to develop a management system for examination bank and an online examination. Working procedures were performed by analysis a traditional working system and problems study of user requirements design of a new working system and a development of the new system. PHP and JAVA programming language operating with MySQL for developments and a database management were used. The new system consists of 6 systems by operating as web application. Users are 3 groups that are teachers students and administrator. In the items analysis stem a reliability value was calculated using KR-20 and KR-21 of Kuder-Richardson. The level of difficulty and discriminating power were identified using choice analysis with 27 percentages of upper and lower technique. The new system was tested with 3 groups of teachers students and administrator. The evaluation was performed using questionnaires. The results of the evaluation shown the contentment is in good level. Accuracy of the system was measured by comparison between a traditional item analysis and the new system. The comparison results were not different. However the accuracy of item analysis results depends on knowledge of the students who are in testing.

The shrinkage depended on the product shape and the type of plastic used in injection melting temperature injection speed holding pressure and mold cooling. Different surroundings during the injection resulted in differences shrinkage so the exact shrinkage value hadn’t been known. This was the cause of Try out and error work that produced Injection products that were not in correct size. This research aims to find the shrinkage percentage based on the ASTM D955 standard test method from high density polyethylene (HDPE) which has partial crystalline structure and high shrinkage. The results were as follows: The specimen size 60x60 mm shrinkage was at 2.57 percentage and with 2 mm thickness the shrinkage was 3.60 percentage. The specimen size 12.7x127 mm shrinkage was between 2.76 percentage and 2.91 percentage with 3.20 mm thickness the shrinkage was 2.48 percentage. For the 100 mm circular specimen the shrinkage was from 4.35 to 4.39 percentage and with 3.20 mm thickness the shrinkage was 2.56 percentage

Brake system is used the friction between disk and pads. In the driving conditions the brake behavior from the driver is difference. Based on this reason the damage on disk and pads are occurring. Nowadays the ratio of compound materials in pads is several and involved automotive industry has not available enough to experiment. Thus it is difficult to brake pads damaged analyzing in several driving conditions. In this problem the mechanical property tester is main tool for experimental works and test procedure base on the Brake lining and disc brake pads compressibility JIS D 4413. The experiment emphasizes on the flexibility behavior and internal energy by volume with 3 types of brake lining and pads. For the experiment focused on conditions by normal apply brake repeat apply brake and suddenly apply brake. The results revealed the normal apply brake condition the maximum and minimum of flexibility behavior was appeared on brake lining and pads type A and type C with testing temperature at 200C. By the repeat and suddenly apply brake conditions the brake lining and pads type C and type A with 300C is given to the maximum and minimum flexibility behavior. In case of internal energy by volume the maximum and minimum energy was appeared on pads type C and type B at the 30C of testing temperature. For the testing temperature at 200 and 400C the pads type A and type B were got the maximum and minimum energy respectively. On the other hand at the high flexibility behavior is given to high internal energy at the high temperature of the apply brake condition.
