title: An interlanguage pragmatic study on the speech act of disagreement performed by Thai EFL learners and addressed to the lecturer in the classroom context

description: The study explored politeness strategies Thai EFL learners used to disagree with their lecturer in English in the classroom context and compared two groups of Thai EFL learners, with less and more exposure to English as a medium of instruction−the EFLt and the EFLe, respectively−in terms of the politeness strategies they used to perform student-lecturer disagreements. Their levels of English proficiency were intermediate as assessed based on their mean scores from the Test of English for International Communication. In the classroom context where there is an asymmetrical power between the students and the lecturer, Thai EFL learners were hypothesized not to use bald on-record strategies. In addition, the two groups of Thai EFL learners were hypothesized to use different politeness strategies due to their different amounts of exposure time to English as a medium of instruction. The data were collected by means of videotaping two classrooms of 18−20 students for 30 hours for 10 weeks. The learners’ verbal expressions of student-lecturer disagreements were analyzed in terms of politeness strategies based on the use of different linguistic features (Rees-Miller, 2000; Kakava, 2004; Locher, 2004; Walkinshaw, 2009; Sifianou, 2012), and secondarily analyzed in terms of paralinguistic features (Rees-Miller, 2000, Kakava, 2002; Hong, 2003), and non-verbal gestures (McClave, 2000; Pease and Pease, 2004; Sifianou, 2012). The results showed that Thai EFL learners used bald on-record strategies to disagree with their lecturer. Furthermore, the two groups of Thai EFL learners normally used different sets of politeness strategies. The EFLt normally used negative politeness strategies, that is, they modified their disagreements through imposition minimizers. The EFLe normally used bald on-record strategies, that is, they disagreed with the lecturer explicitly. This study also investigated what politeness strategies native speakers of Thai (the NT) and native speakers of English (the NE) used to disagree with their lecturers in the classroom context. Results showed that the NT normally used negative politeness strategies while the NE normally used bald on-record strategies. In comparison with the NT’s and the NE’s politeness norms, it was discovered that the EFLt transferred some pragmatic competence in Thai to their production of student-lecturer disagreements in English. However, there was no evidence to conclude that the EFLe’s pragmatic competence in English was fully developed. Having compared the EFLt’s and the EFLe’s politeness strategies they used to perform student-lecturer disagreements in English, the researcher found that their pragmalinguistic competence and sociopragmatic competence were different.

title: Synthesis, sorption and sensing capability of carbon nanotube based materials for gas-phase chlorinated phenols

description: The adsorption equilibrium isotherms as well as gas sensing of three chlorinated phenolic compounds (CPCs) including phenol, 2-chlorophenol, and 2,4-dichlorophenol by acid-functionalized carbon nanotubes (CNT) were studied. CNTs were synthesized via floating catalyst chemical vapor deposition method at 800oC and then functionalized with a mixture of HNO3 and H2SO4. The functionalized CNTs were vacuum filtered to form CNT buckypaper. The adsorption isotherm followed the Langmuir adsorption model better than the Freundlich and Redlich-Peterson models. The maximum adsorption capacities were found to be 61.35, 93.46 and 104.17 mg/g for phenol, 2-chlorophenol and 2,4-dichlorophenol, respectively. The desorption activation energy determined via thermogravimetric analysis indicates that adsorption of all three CPCs onto the CNTs belonged to chemisorption type. For the gas sensing test, the CNT buckypaper showed fast response to the tested CPCs with good stability and repeatability. The sensitivity values obtained were 13.778 × 10-4, 8.835 × 10-4 and 7.122 × 10-4 for 2,4-dichlorophenol, 2-chlorophenol and phenol, respectively. It is noteworthy that the adsorption capacity and sensitivity of the CNT based materials to the target gases increased with the increase in the number of chlorine atoms in the phenolic compounds.

title: Optimization of in-situ transesterification process for soybean and spent coffee grounds biodiesel

description: Soybean and spent coffee ground (SCG) were applied as biodiesel feedstock in the reactive extraction process named in-situ transesterification (in-situ TE). This process reduced the complexity of biodiesel production by combining vegetable oil extraction and biodiesel synthesis into a single step. Several parameters were evaluated for the effect on biodiesel yield. The optimal process conditions using different alcohol systems showed that the stronger hydrophobicity of alcohol system provided the higher biodiesel yield. It also reduced the alcohol and catalyst loading, lower the reaction temperature and shorten the operation time. Simply washing SCG by methanol could reduce acidify of SCG. Elevating temperature could compensate the coarse particle size of SCG. The kinetic results showed that 80% of biodiesel yield could be obtained within 3 h using 4 kg SCG loading. SCG biodiesel produced from in-situ TE had high oxidative stability index due to the co-extraction of antioxidant. LCA results showed that producing SCG biodiesel at an on-site instant coffee process via in-situ TE had lower impacts at industrial level in terms of respiratory organ and land occupation than those of conventional approach because of the absence of n-hexane and transportation. However, it consumed much more energy during methanol recovery step, resulting in more impacts in the overall of health, ecosystem quality, climate change and resource. The sensitivity analysis suggested that producing biodiesel at an on-site was more favorable in term of energy usage once the transportation distance was &gt;180 km with 7 km/L of fuel consumption rate. In the future work to improve energy usage and environmental impact of our process, we could directly reuse catalyzed methanol in the process, or apply countercurrent extraction technique which could reduce the amount of methanol and catalyst in the process.

title: Biodegradation of tiamulin by wood-rot fungi and enriched bacterial cultures obtained from swine farms

description: Tiamulin is a widely used antibiotic in Thai swine farms and persists in manure storage, posing risks related to the spreading of antibiotic and the evolution of resistant bacteria. Twelve strains of wood-rot fungi were collected from swine farms and preliminarily examined for their ability to degrade a recalcitrant compound using brilliant green and crystal violet dyes. Three isolated fungi and three white-rot fungal strains–namely, Lasiodiplodia sp. F1, Fusarium sp. F5, Galactomyces sp. F8, Verticillium sp., Trametes versicolor, and Trametes hirsuta AK4–capable of developing considerable decolorized zones on both dyes exhibited their abilities to degrade 10 mg/L of tiamulin over a period of 12 days: 93.2%, 82.4%, 73.8%, 89.3%, 86.1%, and 66.8%, respectively, and at the rates of 56.7, 6.5, 5.6, 58.6, 56.0, and 6.8 mL/g fungi·d, respectively. Lasiodiplodia sp. F1, Verticillium sp., and Trametes versicolor were able to remove TIA most efficiently (&gt; 85%). Manganese peroxidase was predominantly produced by all strains over laccase and lignin peroxidase suggesting its main role in TIA degradation. In addition, four TIA-degrading bacterial enriched cultures including A (covered anaerobic lagoon source), AN (covered anaerobic lagoon source, nutrient broth), S (stabilization pond source), and SN (stabilization pond source, nutrient broth) were able to remove tiamulin efficiently at concentrations of 2.5 - 200 mg/L with the maximum rates of 99.7%, 99.0%, 99.9% and 99.6%, respectively within 16 h. Monod kinetic values of Ks were 190.9, 469.6, 2000.1, and 206.7 mg/L, respectively and qmax values were 30.7, 63.5, 269.2, and 48.5 mg/L·h. Next-generation sequencing revealed genera Achromobacter, Delftia, Pandoraea in class Betaproteobacteria and genera Pseudomonas, and Stenotrophomonas in class Gammaproteobacteria dominated , indicating that they might contributed to improve tiamulin elimination process. Tiamulin degrading enriched bacterial cultures had an advantage over the tested fungi in term of the degradation rate; however, its application might be limited due to the possibility of spreading antibiotic resistance microbes or genes to environment. Bioencapsulation technique might help to retard the release of microbes. Besides, the extracted fungal manganese peroxidase might be applied to degrade tiamulin. Further investigation is required. In summary, the bacterial enriched cultures and fungi obtained in this study are promising tiamulin degraders that are potentially applied for eliminating tiamulin in contaminated swine manure and wastewater.
