Use of synthetic surfactant is another choice to increase efficiency of polycyclic aromatic hydrocarbon (PAH) phytoremediation in soil. In this study the toxicity of soil contaminated with anthracene and fluoranthene at total concentration as 0 200 and 800 mg/kg in combination with 2 synthetic surfactants that were triton x-100 and tween 80 at concentration as 0 1 and 10 times of critical micelle concentration (CMC) on seedling growth of Hibiscus sabdariffa and Mirabilis jalapa. Both synthetic surfactants were watered separately on day 13 after inoculation and seedling growth were measured on day 20 after inoculation. The result shown that both H. sabdariffa and M. jalapa could grow in soil contaminated with anthracene and fluoranthene at all concentrations in combination with both synthetic surfactants. Tween 80 at 1 time of CMC were the least toxic to H. sabdariffa while toxicity of all surfactants on M. jalapa were not different. Decrease of plant growth depended on the increasing of PAH concentration in soil. With these reasons both plants were possible to use for PAH phytoremediation at total concentration 200 mg/kg in combination with synthetic surfactant

The aims of this study were developed geopolymer matrix for controlled release amoxicillin antibiotic drug in the in vitro gastric and intestines (pH 1 and pH 6.8 temperature 37 ºC conditions). Three formulations of geopolymer tablets (GeAmSF5 GeAmSF7.5 and GeAmSF10) which different silica fume content were used in this study. Geopolymer tablets were measured compressive strength and characterized by using 3D laser microscope Scanning electron microscope (SEM) X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FTIR). The amoxicillin release was analyzed by UV-VIS spectrophotometer. It was found that amoxicillin in geopolymer tablet was more resistance with various extraction solvents (ethanol water 50 oC pH 1 and 12 solutions) than amoxicillin commercial tablet in 2 hours. Moreover the amoxicillin constantly release from geopolymer matrix after 3 hours in both in vitro gastric and intestines. However amoxicillin was more release in gastric than intestines condition due to the strong acid leached aluminum ion causing damages geopolymer structure. Mathematical modeling of amoxicillin release from geopolymer matrix was fitted best with Higuchi model indicating diffusion of the drug out of matrix.

The biosorption of Rhodamine B using modified water hyacinth roots was studied. The adsorption experiments were conducted in a batch setup. Parameters affecting the adsorption of Rhodamine B including pH of a solution adsorption time adsorbent dose and dyes concentration were investigated. With the 80 mg/L Rhodamine B solution of pH 6.0 adsorption time of 60 min and 0.10 g of modified water hyacinth roots the kinetic models pseudo-first order and pseudo-second order kinetic model were applied to examine the kinetic adsorption. The adsorption kinetic data correlates with pseudo-second order kinetic model. The Langmuir and Freundlich adsorption models were applied to describe the isotherms and isotherm constants. Adsorption isotherm data correlates with Langmuir adsorption model. The maximum adsorption capacity of modified water hyacinth roots for Rhodamine B was found to be 63 mg/g

The purposes of the study on factors affecting Scotch brand loyalty were to examine personal factors of Scotch brand purchasers opinions on the brand equity degree of loyalty and brand equity factors that affected Scotch brand loyalty. The data were collected from 405 buyer samples selected from Cochran sample size formula and were analyzed by descriptive statistics including frequency percentage mean and standard deviation. As for inferential statistics Pearson Product Moment Correlation Analysis and multiple regression analysis were applied. The results showed that the opinions on the brand equity factors on three aspects of the brand regarding the brand recognition the brand association and the quality perception were highly regarded. Opinions towards Scotch brand loyalty in terms of attitude and behavioral aspects were also high. The hypothesis test results suggested that factors related to brand equity in terms of brand recognition brand association and quality recognition affected Scotch brand loyalty in the overall attitude and behavior aspects.

This research has two objectives to 1) to analyze the components of ecotourism of Tahin Community Tahin Sub-district Sathingphra District Songkhla Province and 2) to study Ecotourism Supporting Strategies of Tahin Community Tahin Subdistrict Sathingphra District Songkhla Province. This research use mixed methods ; the qualitative and quantitative research. For the qualitative research conduct by in-depth interview 23 key informants which is the tourism management leader in Tahin Community the qualitative data was analysed by componential analysis. The quantitative research using accidental sampling 362 stakeholders in Tahin Community area and was statistical analysed by mean. The results of the research found that 1) component of ecotourism of Tahin Community for tourism aspects are : the community is unique for tourist place because the tourist attraction are various and traditional especially : culture for live their life The Palm Paddy Sea way which are attractive to tourists and the community is also historically valuable. 2) the strategy of promoting ecotourism Tahin Community they should promote tourist attractions or tourists activities the most (X ̅ = 4.26) followed by the tourist service (X ̅ = 4.13 ) and the tourism marketing (X ̅ = 3.95 ) respectively.
