The objectives of this research are: (1) to investigate the potential of agrotourism project sites in Bangkok and its vicinity that are officially recognized as following the principles of the Philosophy of Sufficiency Economy; (2) to create a good relationship between the researcher and the local community tourism academics experts and farmers. This study was conducted by means of semi-structured interviews and questionnaires. The participants are stakeholders including community leaders and agricultural owners. Content analysis was employed to analyze the qualitative data. Descriptive statistics (percentage and mean) was employed to present the quantitative data. The results of this research reveal that: (1) The strengths of the agro-tourism project sites include knowledge of the new agriculture theory and the expertise of owners. (2) The weaknesses include lack of services for tourists rest areas and parking. (3) Base on all 34 indicators of 4 factors the overall averages scores of both agricultural sites are in the intermediate level at 2.24 and 2.11 respectively. (4) The most important factor determining the potential of agro-tourism sites is good attractive location and the least important factor is lack of service.

The potential of extracts of the Ficus hispida Linn to inhibit germination and growth of barnyardgrass (Echinochloa crus-galli) a common weed in rice. The bark leaves and fruit of F. hispida isolated by the Maceration and extracted by the polarity of the solvent (Sequential Extraction) with organic solvents such as hexane ethyl acetate and methanol when each part of the crude extract was tested the type of phytochemical tested for germinate inhibition root length inhibition stem length inhibition and dry weight inhibition of barnyardgrass and selected extracts with highest inhibition to separation using column chromatography the fractions tested repeating. The results showed that 1. Crude methanolic extracts from the bark leaves and fruit of barnyardgrass at a concentration of 3000 ppm showed highest inhibited percentage of germinate inhibition root length inhibition stem length inhibition and dry weight inhibition. 2. Fractions methanolic extracts from the bark leaves and fruit of barnyardgrass on a separate with column chromatography found that fractions extracts F5 F8 and F2 showed highest inhibited percentage of germinate inhibition root length inhibition stem length inhibition and dry weight inhibition.

The study used the bark leaves and fruit of Ficus hispida Linn to separation by Maceration and sequential extraction method with hexane ethyl acetate and methanol to crude extracts. Crude extracts were assessed for their antioxidant activities tested using DPPH radical scavenging assay total phenolic contents tested using the Folin–Ciocalteu method cytotoxic activity against oral cavity cancer (KB) human small cell lung cancer (NCI-H187) and breast cancer (MCF-7) cancer cell lines tested using the resazurin microplate assay (REMA). The results showed that 1. Crude methanol extracts from the fruit exhibited free radical scavenging effect on the DPPH assay with IC50 value of 27 g/ml with the total phenolic contents value of 102.39 mg GAE/g dw of standard BHT. 2. Crude hexane extracts from the bark showed highest inhibited the growth of Vibrio paraheamolyticus crude ethyl acetate extracts from the bark showed highest inhibited the growth of Streptococcus mutans ATCC 27175 and crude methanol extracts from the leaves showed highest inhibited the growth of Vibrio cholerae most with MIC value of 7.80 g/ml. 3. Crude ethyl acetate and methanol extracts from F. Hispida exhibited inhibitory effect against oral cavity cancer (KB) human small cell lung cancer (NCI-H187) and breast cancer (MCF-7) cancer cell lines. These data support traditional uses of F. Hispida in folk medicine

Weather predictions by an atmospheric model are determined by the uncertainties in the initial condition and the imperfection of the model. It is difficult to provide accurate weather prediction. The efficiency of weather predictions model is obtained from the analyses of Lyapunov exponent. In addition the predictability measurements is applied from Lyapunov exponent are finite size Lyapunov exponent finite time Lyapunov exponent local Lyapunov exponent together with a new method called supremum Lyapunov exponent are used to measure predictability of the northeast monsoon (winter monsoon) by the Educational Global Climate Model (EdGCM) and to test sensitivity of the model to small initial perturbations. The EdGCM sensitive to initial perturbations it is suitable for predictability of the northeast monsoon. The EdGCM is run for 142-year predictions from the year 1958 to 2100. However only the outputs of geopotential height at 500hPa of December from 2012 to 2100 are used for predictability measurement. The results show that the EdGCM predictability for the northeast monsoon forecast is about 120 years. So the EdGCM can be predictability of the long range forecast.

The purposes of the research were; 1) to study the relative rotation of AC-generator 2) to study the angular velocities of magnetic coil and permanent magnetic influence generating voltage of AC-generator and 3) to construct predictive equations of generating voltage of AC-generator. By the 12-V 6-pole alternator of motorcycle Pearson’s correlation and regression analysis the findings revealed that: 1) At the lowest relative angular velocity of 376 rpm the generating voltage is 3.28 V. While the highest relative angular velocity of 2280 rpm the generating voltage is 22.98 V. 2) The angular velocity of permanent magnetic has great influences on generating voltage than the angular velocities of magnetic coil at the .01 level of significant and 3) function as below : Generating voltage = 0.806 (Velocity of permanent magnetic) + 0.634 (Velocity of magnetic coil)
