The application of coconut meal, corncob and durian peel as wood-substituted biocomposites in medium density fiberboard
This research aims to study the application of coconut meal corncob and durian peel as wood-substituted biocomposites in medium density fiberboard. The fiber: urea formaldehyde glue: isocyanate glue with polymeric diphenymethane diisocyanate type (pMDI) ratio is equal to 1: 0.13: 0.003. The fibers are taken from coconut meal corncob and durian peel that 7 ratios are used to all of fiber mixing. The fiberboard production use 130?C of temperature with 20 – 50 kg/sq.cm of compressive pressure with 8 minutes per piece of rate. Their fiberboards have 603 – 856 kg/m of density that was tested follow the TIS 876-2547 standard. Resulting the MM33 ratio (coconut meal fibers: corncob fibers: durian peel fibers is equal to 0.33: 0.33: 0.33) and the CC50 ratio (coconut meal fibers: corncob fibers: durian peel fibers is equal to 0.50: 0.25: 0.25) can pass the standard in physical properties and mechanical properties. Moreover their fiberboards have good thermal insulation
Study on the correlation between the degree of milling on quality of rice
The objectives of this research were to find the correlation between the milling degree and the milling quality of rice which was the basic data to investigate the milling degree equipment. Chainat 1 and KDML 105 rice varieties were milled at difference degree of milling (DOM) which calculated from bran removed. The study revealed that as the DOM increase the milled rice and head rice decreases. Therefore the whiteness transparency and milling degree of milled rice which was measured from Milling Meter also increased. When the DOM increased the whiteness transparency and milling degree also increased. The DOM had highly correlation not only to milled rice and bran but also to milling degree from Milling Meter at R2=0.99 and R2=0.97. So these correlations could be used to investigate the milling degree equipment.
Comparison the efficiency of internet services by 3G technology in thailand
Currently the internet services with 3G technology by mobile phone operators in Thailand are different in the performance. The mobile phone operators have already launched 3G technology with 2G frequency ranges which are limited in the efficiency. This paper aims to compare the efficiency of the internet service with 3G technology by three mobile phone operators (AIS DTAC and Truemove H) in Thailand. There are three type of testing as follows: Ping to both domestic and international website Bandwidth speed test and FTP Test (upload and download) are used to evaluate the performance of these mobile phone operators. There were five places in Bangkok where are the top of the network congestion list for such testing the three mobile phone operators. The result showed that AIS gives the best performance in the ping test. Truemove H introduces the best performance in both FTP and Bandwidth speed test. The DTAC performances are moderated level for every tests.
Development of household textiles from batik silk: a case study of the motif of ancient khmer art at sikhoraphum castle
This study aims to develop household textiles from Surin Batik silk with pattern of Ancient Khmer Art at Sikhoraphum Castle and to study customers’ satisfaction of household textiles. The population was 400 assessors within the age range of 20 - 50 years in Surin province. The research instrument was questionnaire. Data were statistically analyzed for Percentage Mean and Standard Deviation. Results showed that the majority of respondents were females with ages around 31 - 35 years old. Most of them were married and had income of 15000 – 25000 baht. Most got Bachelor’s degree and used to use household silk textile. Working clothe was the most purchased category. Most household textiles were purchased as souvenirs. Personal preference was the initial motivation for purchase decisions and utilization was the key factor for selecting a product. Regarding onsumers’ satisfaction in 3 types of household textiles from Mudmee Batik silk - cushion lamp and bed cloth – it was found that satisfaction in style pattern colour price and utilization were in similar high level. Cushion was the most purchased household textile. Peacock was the most favorite pattern and consistency of the pattern was the most important factor for purchasing.
Antibacterial activities of the crude extract of acrostichumaureum l. growing at Rajamangala University of Technology Srivijaya, Trang Campus
The aim of this research was to study the antibacterial activities of crude extract with hexane from the leaves stems corms and roots of Acrostichumaureum L. by disc diffusion method against the pathogens viz. Bacillus cereus TISTR687 Staphylococcus aureus TISTR1466 Escherichia coli TISTR780 and Salmonella typhimurium TISTR292. The results revealed that the leaves extracts showed antibacterial activity onall of fourtested pathogenic bacteria with the inhibition zone of 9.20 0.37 8.92 0.09 6.62 0.48 and7.82 0.56 mm.respectively. While the stems corms and roots extracts showed antibacterial activity ononly B. cereus with the inhibition zone of 8.02 0.25 8.51 0.21 and 10.87 0.13 mm. respectively. This preliminary screening results demonstrated the potential of the extracts from various parts of Acrostichumaureum L. to be used as antibacterial agent and to be further researched and developed into innovative pharmaceutical and cosmetic products.
