 หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Selection of Thermophilic Xylanase Producing Mold) ผู้เขียน: Busaracum Reongosoom สื่อสิ่งพิมพ์:pdf AbstractA total of 238 mold cultures capable in utilizing xylan as sole source of carbon were isolated from decomposed lignocellulosic materials. Based on the ability to produce high xylanase activity at 45C, 65 isolates were selected. All cultures produced enzymes which hydrolyzed xylan to xylose and xylo-oligosaccharides. The most efficient strain, designated No. 4-45-1F produced as high as enzyme 36.6 units/ml. Regarding to the screening procedures, it was found that activity of the enzyme produced by the cultures was not quantitatively related to size of the clear zones which was developed by flooding the xylan agar plate with iodine solution. All the selected cultures belong to the genus Aspergillus. The best strain was identified as Aspergillus fumigutus Fresenius. |
 หัวเรื่อง:การคัดเลือกลายผ้าทอพื้นบ้านและถ่ายทอดนวัตกรรมในจังหวัดนครสวรรค์ ผู้เขียน:Busaracum Reongosoom สื่อสิ่งพิมพ์:pdf AbstractThis research was conducted to find out the general background and the condition of hand-made cloth industrial movement in Nakhon Sawan province. It was concentrated on searching for the possible conservation pattern of hand-made cloth as the innovative technology for dissemination of innovations to the people who have taken it as their major occupation. This research also aimed to find out the relationship among those of independent variables of 3 categories : local weaving design, the Industrial Promotion Department's design, and personal design. The 38 patterns of hand-made cloth were the subject to find out the possible ways for dissemination of innovative technology. The methodology therefore, were both qualitative and quantitative research. SPSS/ FW Version 9.0 was used to find out the coefficient correlation and the significant differences among the independent and dependent variables. It was found that 38 patterns of hand-made clothes were under the criteria and being indicators for the selection of reserved materials. The target group for dissemination was composed of 134 persons (39 conservatives and 95 new stylists). The average age was 44.05 years old, while the level of education was more than 98 percent graduated at graduated at grade 4-6 and illiteracy. The average annual income from the major occupation was 33,334.51 baht per head and from other sources was about 8,976.92 baht. The majority (69.4%) were the people of the local weaving group numbers in Nakhon Sawan area. They also had the average of 5,191.75 baht per person per year for investment. The majority (87.3%) made clothes for personal use and for sales. In testing the hypothesis, It was found that the null hypothesis was accepted in 39 out of 99 sub hypothesis. There were also the possible alternative suggestion for these who are interested in dissemination of innovative technology. |
หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Responses of Soybean Varieties to Saturated Soil culture) ผู้เขียน:Busaracum Reongosoom สื่อสิ่งพิมพ์:pdf AbstractA series of two experiments were conducted to study the responses of five soybean varieties under saturated soil culture at Kasetsart University, Kamphaengsaen campus in 1986 late rainy season and 1987 dry season. Asplit plot desigh in RCB with 3 replications was employed with soil-water regimes as main plot and soybean verieties as subplot. Main plots were conventional varieties were locally recommended varieties except A 138 and P 44 which were introduced from Australia. It was found that under saturated soil culture growth and yield of soybean tended to be lower than conventional irrigation and local varieties seemed to be more affected than Australian varieties. In terms of dry weight accumulation soybean varieties tended to saturated soil culture but nodule production and nitrogen especially in later stages of growth. However yield and yield components of both methods were not statistically sighificantly though in favour of saturated soil culture. It was found that Thai varieties adapted and yield quite well under saturated soil culture though inferior to introduced varieties. It could be concluded that raising yield level in saturated soil culture is possible if late varieties are grown in dry season where prevailing environmental conditions are more favourable. |
หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Response of Four Tropical Pasture Grasses to Nitrogen Application) ผู้เขียน:Busaracum Reongosoom สื่อสิ่งพิมพ์:pdf AbstractThe response of Para (Brachiaria mutica), Rhodes (Chloris gayana), Buffel (Cenchrus eiliaris) and Giant pangola (Digitaria spp.) grasses to nitrogen fertilizer at 0, 30, 60, 90 and 120 kg N/ha/cut was conducted at Packchong Animal Nutrition Research Centre, Nakhon Rachasima from September 1979 to July 1980. Six harvests were made at 45-50 day intervals. Rhodes grass gave the highest total dry matter yield (22,049 kg/ha), followed by Buffel, Para and Giant pangola (21,644, 16,866 and 15,269 kg/ha, respectively). There was a significant response in dry matter production to the application of 60 kg N/ha/cut cut no significant response beyond that level due to the soil moisture and temperature limitations to growth. The nitrogen response recorded occurred mainly in the early rainy period towards the end of the experimental period. Crude protein contents of the grasses tended to increase with nitrogen fertilizer applications, being generally low in the October harvest but quite high in the March harvest at the end of dry season, especially in Giant pangola and para grass. Para and Giant pangola grasses were noticeably nore efficient in terms of dry matter production per kg of N applied (18 kg DM/kg N ; 17 kg DM/kg N respectively) than Rhodes and Buffel grasses (8 kg DM/kg N ; 5 kg DM/kg N respectively). |
