การศึกษาระยะเวลาอบแห้งที่เหมาะสมและลักษระทางกายภาพของหมูแผ่นอบแห้งด้วยไมโครเวฟตามด้วยอากาศร้อน
The objectives of this research were to determine the suitable times of pork slices drying using microwave followed by hot air and to find specific energy consumption during drying. The physical characteristic (color and hardness) and the sensory test of dried pork slices were also investigated. Pork slices with the sizes of 50x50x1.3 and 50x50x2.2 millimeters were dried using the microwave at the powers of 160 320 480 640 and 800 watts until the samples did not burn during drying. Then the samples were dried using hot air at a temperature of 110oC until the moistures of the samples were lower than 20% dry basis. Based on the experimental results it was found that the suitable times of the samples drying using microwave were 50-600 seconds which depended on the microwave powers and the pork thicknesses. In hot air drying period drying times of the samples with thicknesses of 1.3 and 2.2 millimeters were 30 and 45 minutes respectively. The microwave powers had no significant effect on the redness (a value) and yellowness (b value) of dried pork the hardness of dried pork and the specific energy consumption (P<0.05). The pork thicknesses had the significant effect on the lightness (L value) and yellowness (b value) of dried pork the hardness of dried pork and the specific energy consumption (P<0.05). Moreover sensory scores of the dried pork obtained from this research were close to those obtained from the local market.

The biosorption of phosphate using modified cassava waste were studied. Cassava pulp was modified in methylamine for the adsorption of phosphate ion in aqueous solution. XRD SEM and FTIR result confirmed the surface modification of modified cassava waste. The adsorption experiments were conducted in a batch reactor. The studied parameters included pH contact time and initial concentrations. The amount of phosphate in the solution was measured by Vanadomolybdophosphoric acid method. Optimum conditions of adsorption were 0.10 g of modified cassava waste pH 4 and 5 hour of contact time at 25 mg/L of initial phosphate concentration. Kinetic of adsorption were studied by using the pseudo-first and pseudo-secondorder models at room temperature. The results indicated that the pseudo-second-order model best described adsorption kinetic data. The Langmuir and Freundlich adsorption models were applied to describe the isotherms and isotherm constants. The adsorption of modified cassava fitted well with the Langmuir model and the maximum adsorption capacity of 5.128 mg/g; and the active site of adsorption was amine functional group. Phosphate released in water reach equilibrium within 4 days.

This research was to study inherit and existence of Nora Rongkru Phatthalung Province. Use the qualitative research methodology to collect data from people about inherit and people attending Nora Rongkru Wat Tha Khae. The data were analyzed for descriptive purposes. The results showed that Nora’s existence is born of faith and faith. Wat Tha Khao ls a ritual source The nature of the event. Ritual participants Sacrificial Costume instrument place time meaning of the ritual Nora the successor to the third generation and the successor of the ritual. The existence of Nora is strictly and the role of the ritual continues to the present the functions of inheritance faith inheritance identity the duty to create mental security fun to entertain and the duty of communication. The succession and existence of the Nora teacher Tha Khao to generation.
การคัดแยกแบคทีเรียส่งเสริมการเจริญเติมโตของพืชจากดินบริเวณรอบรากต้นกระดุมทองเลื้อย (Wedelia trilobata (L.) A.S. hitchcock)
The objective of this research was to isolate plant growth promoting rhizobacteria from Wedelia trilobata (L.) A.S. Hitchcock rhizosphere and preliminarily test their plant growth promoting properties such as nitrogen fixation siderophore production phosphate solubilization and indole-3-acetic acid production. Forty-seven bacterial isolates were obtained including 26 isolates of gram positive 18 isolates of gram negative and 3 isolates of actinobacteria. After that 8 isolates (including BWTM1_MSU BWTM2_MSU BWTM5_MSU BWTM6_MSU BWWM6_MSU BWWM8_MSU BWWM9_MSU and BWWM16_MSU) were selected for studying on root colonization and plant growth promoting properties under aseptic condition. The results showed that BWTM5_MSU had the evident on the promotion of plant growth with the most percentage of rice seed germination (63.33%) high level of root and shoot length with 6.11 cm and 3.89 cm respectively. As a result the root and shoot fresh weight was as high as 9.56 mg and 11.33 mg respectively. It also correlated with the highest production of indole-3-acetic acid up to 421.29 ug/ml. The root colonization was studied by counting rhizobacteria isolate BWTM5_MSU from rice rhizoplane and rhizosphere with presented bacterial number at 9.67x106 CFU/g root and 1.64x10 10 CFU/g soil respectively.

The Thai wisdom knows the benefits of Carissa carandas L. to be used as a traditional herbal medicine. However there was no scientific evidence to show that Carissa carandas L. of Thailand can treat gout or not. In this research the Carissa carandas L. fruit extract in semi-ripening and ripe stage were studied for the phytochemical and inhibitory activity of xanthine oxidase one of the causes of gout. The result of hytochemical indicated that the crude extract from semi-ripening stage fruit contained many substances; phenolic compounds alkaloids flavonoids terpenoids saponins and deoxy sugars. While the ripe stage fruit contained the similar substances excepted saponins. The extract solution of Carissa carandas L. showed the xanthine oxidase inhibitory activity as the ethanolic extract solution gave the higher activity than water extract solution. The crude extracts of semi-ripening stage fruit presented the higher activity than the ripe stage one with the IC 50 values of 2.40 ± 0.05 and 2.87 ± 0.37 mg/mL respectively. The result of ripening stage with different phytochemical may be related to inhibition of xanthine oxidase activity. Therefore the selecting of sampling period and purification of extract may be a choice for using as medicine for gout
