A semi-solid state fermentatiom of bioethanol using durian fruit - hull as nutrien source
A semi-solid state fermentatiom of bioethanol using durian fruit - hull as nutrien source

จากการวิจัยเรื่องการหมักเปลือกทุเรียนแบบกึ่งแห้งเพื่อผลิตไบโอเอทานอล เป็นการอนุรักษ์ทรัพยากรธรรมชาติ และประยุกต์ใช้ของเสีย (Residue/waste) ที่ได้จากการเกษตร เป็นจุดเริ่มต้นของความจำเป็นเร่งด่วนในการพัฒนาเพื่อให้ทรัพยากรที่มีอยู่ให้เกิดประโยชน์สูงสุด โดยการนำประโยชน์ของเปลือกทุเรียนที่เป็นของเหลือ ทิ้งทางการเกษตรที่มีในท้องถิ่น เพื่อนำมาแปรรูปหมักเพื่อให้ได้แอลกอฮอล์เพื่อใช้ประโยชน์เป็นพลังงานเชื้อเพลิงทดแทนน้ำมัน อันก่อให้มีมูลค่าเพิ่มสูงขึ้น เพื่อลดปริมาณสารที่จะต้อง กำจัดก่อนปล่อยออกจากโรงงานอุตสาหกรรม

The development of medicinal plant extracts to control Weed germination and growth
The development of medicinal plant extracts to control Weed germination and growth

Study on the inhibition of germination and growth of weeds in rice fields. The extract from the leaves of Xy/ocorpus gongeticus Parkins and Porinori onomense Hance using fermentation Maceration and extraction techniques for Sequential Extraction with three types of solvent hexane ethyl acetate and methanol. The resuLts showed that Leaf extract of Xy/ocorpus gongeticus Parkins with ethylacetate at a concentration of 2000 -3000 ppm showed the highest inhibition of germination and growth of weeds. When the substance to be separated by chromatographic techniques showed that the extracts inhibited the germination and growth percentage of Fl is the highest. Leaf extract of Porinori onomense Hance with hexane at a concentration of 2000 3000 ppm showed the highest inhibition of germination and growth of weeds. When the substance to be separated by chromatographic techniques showed that the extracts inhibited the germination and growth percentage of F4 is the highest. Which can be used for research and development of natural products from plants to control weeds in rice fields to develop further research to commercialization

A test kit for measuring total antioxidant capacity
A test kit for measuring total antioxidant capacity

According to the studying this research absorbance detection system for flow injection analysis system was constructed by using syringe pump so the problem of bubbles in the system was solved successfully. The principle of the test-kit based on pushing the solutions into the system using double two ml syringe pumps. The solutions were mixed at mixing coil then the solution of the sample was inserted automatically by using six-port-valve. The detector was built from light-emitting-diodes (LEDs) with the wavelength at 620 nm. The product solution in cuvette was exposure then the light energy was transferred to electric current by photo-diode. The electricity was changed to voltage to micro-controller. The absorbance was calculated. The results absorbance and flow rate were controlled by utilization of Labview software. The absorbance of the samples from the developed system was compared to the commercial spectrophotometer. The mean absolute percentage error of the flow rate was 1.2%.

Risk factors for dengue fever in Thailand using mathematical Generalized Estimating Equation (GEE)
Risk factors for dengue fever in Thailand using mathematical Generalized Estimating Equation (GEE)

The objectives of this research were to investigate risk factors for Dengue fever in Thailand and to select an appropriate model. The generalized estimating equation (GEE) whose dependent variable has a Poisson distribution and a negative binomial distribution were studied. The secondary data consisting of the number of Dengue fever patients rainfall average temperature forest area household income were collected. Regions and seasons were also considered. The research found that the GEE whose dependent variable has a negative binomial is more appropriate to be used for Dengue patient data analysis. Central region and the season during Feb-Apr were assigned to be reference groups. Risk factors for Dengue fever were rainfall (Relative Risk (RR) = 1.0009) average temperature (RR = 1.1736) forest area (RR = 1.0482) southern region (RR = 2.7390) eastern region (RR = 2.0489) western region (RR = 1.4051) the season during May-Jul (RR = 3.0526) and Aug-Oct (RR = 3.2677)

Art-culture and environment web content management system of community
Art-culture and environment web content management system of community

The objectives of this research are to analysis design and develop the art-culture and environment web content management system of community. Also to install transfer knowledge from research to member of community test and evaluate the system. The system developed by Joomla version 1.7 and tool of technology web 2.0. And the system is installed on the internet server. To evaluate the satisfaction the 2 groups are the samples. The first is the group of 5 operation users and second is the groups of 30 participator in research knowledge transfer project. The results of research show that the system can be installed in real working and suit the user requirement. And the satisfaction of the first group is a high level. For the satisfaction of second group is highly. After that second group can apply knowledge from research to manage data and patent of 3 web sites.
