This research aims to study phytochemicals and potential of Mapok (Parinari anamense Hance) extracts to inhibit germination and growth of Barnyard grass (Echinochloa crus-galli) a common weed in the rice fields. Organic solvents extracted the part of fruits barks and leaves of Mapok included hexane ethyl acetate and methanol. Crude extracts compose of fruit hexane extract fruit ethyl acetate extract fruit methanol extract bark hexane extract bark ethyl acetate extract bark methanol extract leaves hexane extract leaves ethyl acetate extract and leave methanol extract. Crude extracts were tested of phytochemical tested of germinating inhibition root length inhibition stem length inhibition and dry weight inhibition of Barnyard grass. Leaves ethyl acetate extract showed highest inhibit germination and growth of Barnyard grass The leave ethyl acetate extract was separated by column chromatography to yield nine fractions (F1 – F9 fraction) and tested inhibit germination and growth repeating. The results showed that 1. The crude ethyl acetate extracts from the bark of Mapok at a concentration of 3000 ppm showed the highest inhibited percentage of germinating inhibition root length inhibition stem length inhibition and dry weight inhibition. 2. Fraction F8 of leaves ethyl acetate extract showed the highest inhibited percentage of germinating inhibition root length inhibition stem length inhibition and dry weight inhibition.

In this work the objective is to develop the bilayer structure consisting of hydroxyapatite-alumina (HAp-Al2O3) layer and 3 mol% yttria tetragonal zirconia (TZ-3Y) layer using conventional technique consisting of the simple pressing together with pressureless sintering. In order to obtain the desired characteristics of bilayer structure layer thickness cosintering temperature and Al2O3 addition on successful fabrication of HAp-Al2O3/TZ-3Y bilayer structure are investigated. The results indicated that the HAp-10A/TZ-3Y bilayer structure was successfully fabricated by single-end die pressing the powders in hollow cylindrical graphite die under 60 MPa pressure and further wet-bag isostatically pressing in oil to 300 MPa pressure before sintering at 1200 ˚C for 1 h. It is found that an addition of 10 vol% Al2O3 into the HAp outerlayer is the essential condition to effectively suppress the differences in densification and coefficient of thermal expansion of the two layers during cosintering at 1200 oC for 1 h. The obtained HAp-10A/TZ-3Y bilayered disc has diameter of 21.0 mm HAp-10A outerlayer of 4.5 mm thick and TZ-3Y underlayer of 2.5 mm thick. The XRD pattern of the powders crushed from its HAp-10A outerlayer revealed no transformation into other new phases demonstrating that there is no reaction between HAp and Al2O3 during sintering at 1200˚C. The cross-section morphology of HAp-10A/TZ-3Y bilayered composite obtained from the SEM result revealed the porous structure with good interconnectivity. The high porous structure of the bilayered composite provided high surface area for cell attachment indicative of good cell growth and differentiation. The primary grain sizes of HAp-10A outerlayer and TZ-3Y underlayer were in the range of 1-3 um and 100-500 nm respectively. The hardness of HAp-10A layer and /TZ-3Y layer in bilayer structure varied with different layer thicknesses. Accordingly the results presented in this work demonstrated that the HAp-10A/TZ–3Y bilayered composite fabricated by simple technique has thick HAp-Al2O3 outerlayer and strong interfacial bonding between interface layers which can be tailored for specific applications

This research to examine the structure and mechanical properties of aluminum dross. A research project knowledge the aim is to study the microstructure and the mechanical properties of materials. The research is divided into two parts: 1 . preparation aluminum dross material and 2. to determine the structure and mechanical properties. The material must be washed in preparation contamination and dry then crushed and sifted to 200 mesh. Analyzed the microstructure with SEM which indicated the microstructure. The amount of alumina in aluminum dross grade No.0 has 8 0 percent with a powder aluminum dross grade No.1 is a hunk with crystalline alumina component 85 percent. Aluminum dross grade No. 2 which is a big hunk has crystalline alumina components 9 0 percent. Analysis results indicates that aluminum dross can be applied to other aspects such as to produce bulletproof vests and so on.

This quantitative research aimed to promote 360 degree virtual Reality tourism of Ko Pha Ngan Surat Thani province. The research is presented virtual reality 360 degree with moving the camera 360 degree and still the camera to study the satisfaction of tourists to 360 degree virtual reality tourism media. The informants were male and female tourists who have never travelled to Koh Phangan between the ages of 15 - 45 years and living in Bangkok 400 people. The data were collected by using quantitative research. The sorting data collection search from documents study of the results of promoting tourism in Koh Phangan by using Virtual Reality to collect data and using tools such as structured interviews and surveys.

“The Development of Decoupaged Lanna Pattern Bamboo Curl Folk Craft by Ban Rong Don Chai Community in Sarapee Chiang Mai of Thailand” research project’s objectives are 1) To design Thai Lanna pattern for decorates the decoupaged bamboo curl folk craft 2) To survey the decoupaged bamboo curl folk craft customers satisfaction 3) To provide the knowledge and technology on Decoupaged Lanna Bamboo Curl Folk developing The research instrument is a target satisfaction survey which has been analyzed on descriptive statistics . Studied and designed unique Lanna patterns from 3 important religious places of Chiang Mai- Wat Pra Singha Woramahawihan Wat Duang Dee and Wat Chedi Luang which has their own different outstanding Lanna art. 1) Splendid stucco art from Wat Pra Singha Woramahawihan 2) Finely wood carving art from Wat Duang Dee 3) Brilliant Lacquer and gold leaves art from Wat Chedi Luang Woramahawihan Their outstanding Lanna art has inspired a new design which has developed to use for decorating the Lanna bamboo curl folk craft such as home decor souvenirs and home utensils. 25 targets of the satisfaction survey have been impressed on “The Development of Decoupaged Lanna Pattern Bamboo Curl Folk Craft by Ban Rong Don Chai Community in Sarapee Chiang Mai of Thailand” research project. Considering on each field- subject curriculum design expert materials facilities value and utility got the highest impressions scores. The overall averages also shows that every fields got the impression score on ‘most satisfied’
