This research was aimed to study melting behavior of paraffin wax and to evaluate the natural heat convection coefficient of solid cylinder paraffin wax. Two grades of solid paraffin wax; white commercial grade and yellow market grade were studied. Three sizes of flat test tube in diameter 1.5 2.0 and 2.5 centimeters were used. Three different amounts of paraffin indicated from samples’ heights of 5 7 and 10 centimeters were set. The results found the average melting point of both grade paraffin ranged from 44-77 oC. Based on the numerical analysis heat behavior of solid cylinder paraffin at the initial temperature of 50 oC to room temperature of about 30 oC found that natural convection coefficients was ranged from 3 to 9 W/m 2oC. Melting point temperature was found mass independent property while natural convection coefficient declined as the sample’s diameter size inclined

The purpose of this research was to develop bagasse packaging antagonizing fungi with turmeric extract for Green Cos Lettuce cultivation. The bagasse package would incorporated with fungistatic turmeric extract instead of using chemicals at concentrations 0 5000 10000 15000 and 20000 ppm. The packaging characteristics efficiency of turmeric extract and the growth of Green Cos Lettuce determined into the percentage of germination height measurement fungi contamination characteristic were tested under the presence and absent antifungal bagasse The plant seedling spreading onto the surface of the packaging with turmeric extracts could be excelled for -their growth with the induction of germination rate of 92-97 percentages. Turmeric extracts at concentrations of 15000 and 20000 ppm had also expel the emergence of Penicillum sp. inhibit Rhizopus sp. and slow down Colletotrichum sp. Moreover the turmeric extract caused packaging decaying by itself slowly possibly helping in common airborne mold prevention. This green safe material showed the respectably effective for Green Cos Lettuce seedling especially for the fungal pathogen contamination during implantations. This research based on using natural extracts and natural fibers from agricultural waste is thus being ecofriendly nonchemical application of packaging product with easily digested for decent consumers who love their health and care environment.

Football is a sport that has been the most popular for many years. There are many different levels of competition and there is a tendency to develop more globally At present Thailand has a growing number of professional footballers Having traveled to play more professional football in foreign countries The world ranking of the Thai national team is likely to improve in the future The side cannot support in the future The Football Association of Thailand under the Royal Patronage of Thailand has a plan to build a Thai national football stadium To meet FIFA standards for the development of football to support future competition Therefore a study was conducted to design a 60000 seat football stadium project located at Bang Sue District Bangkok To promote the development of football as a center of activity collecting displaying information about football history Is a learning area Create a unique tourism promotion

Doi Inthanon Forest Nature Learning Area. Case study on relationship between learning and physical behavior of Doi Inthanon is a project that creates experimental architecture caused by finding a balance between learning behavior and the needs of the context to be consistent with the physical forest education on. Doi Inthanon in each area Which Doi Inthanon has a learning area that varies according to the overlapping of different nature in many forms according to the study area A. The first form is an open area in the community area. B. The second form is a semi-overlapping natural area. C. The third form is the natural overlap area. There is a form of usage based on the freedom of the user. Therefore the purpose of the project is education. To find ways and tools to design and create a space to connect users with nature Including being a learning area for those who are interested Using architecture as a link to learning relationships In order to be appropriate for the behavior of the physical user with the aim of studying this thesis topic as a case study In creating experimental architecture in each area of Doi Inthanon By using learning behavior of users in each area to study and experiment to form images To meet the needs of the area The interaction and consistency between the architecture people way of life and context

The purposes of this research are : 1) effectiveness of teaching of multimedia teaching materials Basic Subjects Inventions About Artificial Flowers for students of Home Economics Saowabha Vocational2) a study of student is satisfaction with teaching of multimedia teaching materials Basic Subjects Inventions About Artificial Flowers for students of Home Economics Saowabha Vocational and 3) the assessing is possibility and the usefulness of the medium of teaching of multimedia teaching materials Basic Subjects Inventions About Artificial Flowers for students of Home Economics Saowabha Vocational. The population of the study is that students of Home Economics Saowabha Vocational 1st year about 19. The instruments used in this research include multimedialearning assessment tests and questionnaires. The statistics used in this study include E1 / E2 average and the standard deviation. The research found that as follows: 1) students were evaluating during the study a performance fee equal to 80.68 and the assessment report. The performance was 85.74 indicating that the medium of instruction multimedia performance was in accordance with the specified criteria. 2) Student satisfaction with teaching the basics of multimedia creationThe flowers were ; 2.1) the invention of paper roses student was satisfacting the high level.The first two items in order from most to least found that the side with the highest mean score. The media was inferior to the benefits they were receiving from the media and the minimum content. 2.2) Artificial flowers from tissue paperstudent has been satisfacting the high level the first two items in order from most to least found that the side with the highest mean score. The benefits were receiving by the media followed by the media minimum and content and 3) the assessing possibility and the benefits of will have been learning the basics of multimedia creation. The Artificial Flowers Overall were experts opine that appropriate possibility and helpful the high level.
