This study was undertaken to determine effect of bio-extract fermented from pig placenta and effect of wood vinegar solutions on seed germination percentage and speed of germination of 2 rice cultivars Chai Nat 1 and Sang Yod Phattalung. The experiment was conducted in factorial in completely randomized design with 2 factors and 4 replications. The first factor was ratios of the solutions to water and the second was duration for seed incubation. The results demonstrated that wood vinegar showed more positive effect on rice seed germination performances than that of bio-extract. Speed of germination was affected by an inter-action between the dilutions of the solutions and the duration for seed incubation. In Chai nat 1 experiment the seed soaked in 20 times dilution of bio-extract and subsequently incubated for 24 hrs increased speed of germination of the seed. While soaking the seed in 400 times dilution of wood vinegar and incubated for 24 hrs could enhance both percentage and speed of the seed germination. In Sang Yod Phattalung experiment soaking the seed in 50 times dilution of bio-extract and subsequently incubated for 48 hrs or soaking the seed in 300 times dilution of wood vinegar and incubated for 48 hrs could enhance both percentage and speed of seed germination. According to the results we concluded that soaking rice seed in bio-extract of pig placenta fermentation or in wood vinegar solutions could enhance the seed quality.

The effect of azimuth and pot color on the variation of pot surface and growing media temperature was studied. Four pot colors that including with black brown silver and white color were used. The growing media comprised with soil : rice husk : coconut dust at 1:1:1 ratio. From the result of this study the azimuth and pot color effected the variation of pot surface temperature. The azimuth effected the variation of pot surface temperature at 8.00 10.00 14.00 and 16.00. At 8.00 and 10.00 pot surface temperature in east direction was the highest while at 14.00 and 16.00 pot surface temperature in west direction was the highest. Whereas pot color effected the variation of pot surface temperature at 8.00 10.00 and 14.00 with black color was the color that had the highest 33.3 39.1 and 46.4 C respectively. On the other hand the white color was the color that could the highest reduces the pot surface temperature when compared with the temperature of black pot color which were 4.6 3.9 and 4.3 C lower than that in a black pot respectively. Not only the effect on the variation of pot surface temperature pot color was also affected on the variation of growing media. Pot color effected the variation of growing media temperature during 8.00 to 18.00. When compare the growing media temperature among the pot color with that in black pot color which was the highest temperature white color pot was the highest efficiency to reduce the growing media temperature especially at 10.00 and 12.00. White pot color could reduce the growing media temperature about 5 C follow by silver color pot was about 3 C while the growing media temperature in brown color pot was not difference with that in black color pot

This study evaluated the genetic diversity of two natural populations of Neolissochilus stracheyi in Nan River watershed Amphoe Bokluea (BK) and Amphoe Mae Jarim (MJ). We analyzed microsatellite markers originally developed for Tor tambroides (Nguten et al. 2009). Three out of five microsatellite loci analyzed were polymorphic . Genetic variation within BK and MJ populations were not different. The number of allele per locus and allelic richness averaged over three loci was 2.33 and 2.67 for BK and MJ respectively. Observed heterozygosity value was 0.50 and 0.56 and the average expected heterozygosity was 0.41 and 0.53 for BK and MJ respectively. In addition the two populations were genetically distinct (P<0.05) and geographic isolation of two locations may explain this genetic pattern.

Biodegradable polymer blend fibers were prepared by melt spinning technique. Poly(lactic acid) (PLA) and poly(butylene succinate) (PBS) were blended in a twin screw extruder at various contents of PBS at 0-50 wt%. PLA/PBS blends were melt spun using a single screw extruder equipped with multifilaments spinnerette. The effect of PBS contents on morphology thermal properties and mechanical performance of PLA/PBS blend fiber was investigated. SEM micrographs indicated that the addition of PBS at 10 wt% showed miscibility of PLA/PBS blends while the other contents of PBS exhibited phase separation of the blends. The incorporation of PBS affected on the declination of crystallinity in the blends. It can be noted that the addition of PBS could enhance the elasticity of PLA/PBS blend fibers.

This research aimed to investigate the students’ professional problems during their internship from the perception of workplace. The population was 66 informants who the sample was 43 selected by purposive quota sampling Research data were analyzed by descriptive statistics percentage mean and standard deviation and multiple regression analysis The research finding showed the findings showed that (1) the students’ fundamental proficiency problems in front office department were overall at the “Little Level”. A questionnaire 3 dimensions: the students’ fundamental proficiency core proficiency and additional proficiency problems. (2) The students’ fundamental proficiency problems in food and beverage department were overall at the “Little Level”. A questionnaire 3 dimensions: the students’ fundamental proficiency core proficiency and additional proficiency problems. (3) The students’ fundamental proficiency problems in housekeeping department were overall at the “Moderate Level”. A questionnaire 3 dimensions: the students’ fundamental proficiency core proficiency and additional proficiency problems.
