The purpose of this research was to develope the laboratory waste management and provide this knowledge to the students and the research assistants of Faculty of Pharmacy Mahidol University by using the methodology of participatory action research (PAR). This project was performed by training course and releasing the method of waste management by different medias. After the training the 80 participants have been assessed the knowledge using the Scoring Rubrics as a criterion for the evaluation. The result showed that the participants understood about the wastes storage systems the wastes categories the wastes labelling types the wastes containers drop points of wastes the useful of waste storaging the officers who responsible for the storage of waste in the laboratory in the percentage of 97 94 87 97 97 100 and 98 respectively which all passed the specified criteria. The summary of comments and suggestions were that the containers to collect the waste were not enough due to there were many varieties of solvents. This research enables the users to know how to dispose the wastes by differentiating the chemicals types and perform accurately which leading to the reduction of the amount of hazardous waste reduction the unknown waste the waste management from the laboratory become more systematic which will reduce the budgets and decreasing the risk to the health.

This purpose of the research was to study of Solar Absorber Shape Effect in the Solar Air Heater. These has designed and constructed the solar air heater for drying agricultural products of two different types. Comparison of First thing used square type one glass layer used centrifugal fans to feed air and installed solar absorber which each made of sinusoidal corrugate galvanized steel sheet coated with dull black paint and each other made of trapezoidal corrugate galvanized steel sheet coated with dull black paint. The results of research showed that the solar absorber which each made of trapezoidal corrugate galvanized steel sheet coated with dull black paint is most suitable. Which has overall thermal efficiency 66% and can generate maximum temperature 96.13 degree of Celsius

The objective of this research is to study the dispersion of copper oxide particles in water using as a coolant in heat exchangers. Copper oxide particles were prepared by precipitate method. The parameters affected to dispersion of copper oxide were pH of solution and ultrasonic time. The results showed that an average crystalline size of copper oxide was in nano scale (< 22 nm). At pH value of 13 copper oxide was well dispersion in the water. Appropriate ultrasonic time of dispersion is dependent on particle sizes of copper oxide. The small particle sizes of copper oxide led to decreasing of ultrasonic time. On the other hand an increasing in particles sizes required longer ultrasonic time. Stability of suspension of CuO in the water decreased with an increasing of time. Moreover it was found that CuO particles were well dispersed in the water at pH value of 13 and ultrasonic time of 15 minutes

This study aims to develop a new evaluation technique for Northern Corn Leaf Blight (NCLB) resistance in maize under greenhouse condition. Ki48/Ki47 F2 (160 lines) and 2 commercial verities (Hi-Brix3 and Insee2) were evaluated. For this technique 10-14 day old seedlings (4-5 leaves) were sprayed with ACIL1 spore suspension (104spores/ml.) for infection. The results of this technique correlated with the results from the common technique under field condition which used 21-25 days old seedlings (6-7 leaves) (correlation value = 0.658). This evaluation technique was used to assist in QTL mapping of NCLB resistance. Population of Ki48/Ki47 F2 (160 lines) were analyzed for QTL mapping by using Simple Sequence Repeats (SSR) markers. It was found that major parental polymorphism located on chromosome 5 and chromosome 8. When Single QTL analysis was performed SSR marker UMC1365 could clearly indentified qualitative trait loci on chromosome 5 and SSR markers UMC1095 UMC1268 and UMC2356 could clearly indentified qualitative trait loci on chromosome 8.

The purposes of this research were to 1) explore and collect a problem and an obstacle of tourism management by Klong Dan community 2) analyse a problem and an obstacle in tourism management by the community and 3) the study guidliness to develop tourism by the community. The population of the study are government and private organizations community leaders technocrats researchers who used to study in the area OTOP group and tourists The sampling technique for the sample is Simple Random Sampling. The data were collected by interviewing people who involved in tourism management and using questionnaire with the tourists. The data were analyzed according to the content and presented by descriptive analysis and tables. The study found that people in the community are involved in conservation plan and tourism management as well as tourism activities. There are community rules according to covenant community and want to have support from the outside. Beside there are development plans to develop the area as a cultural destination which recognizing the unique art and culture and vernacular architecture of the community. Facility constructing must consider to aesthetic social and culture. The used materials must be able to preserve the unique of local architecture. Furthermore there must be the promotion of the tourism destination to connect with other communities.
