title: Synthesis and application of polydiacetylenes containing amino group for sensing anionic surfactants

description: In this contribution, the colorimetric sensor array for anionic surfactants detection based on polydiacetylene (PDA) was prepared. PDA sols containing amino group such as primary amine, secondary amine, or quaternary ammonium as the polar head group were prepared from diacetylene lipid monomers upon 254 nm UV irradiation. The addition of anionic surfactants such as sodium dodecanoate (SDC), sodium dodecyl sulfate (SDS), or sodium dodecyl benzene sulfonate (SDBS) into the PDA sols induced color transition from blue to red at micro molar level concentration. The colorimetric changes of PDA sols were also monitored by UV-visible spectrophotometer as well as photograph recorder. The addition of cationic surfactants such as dodecyltrimethylammonium bromide (DTAB), tetradecyltrimethylammonium bromide (TTAB), and hexadecyltrimethylammonium bromide (HTAB), however did not show any colorimetric change while nonionic surfactants such as tween20, brij@58P, and tritonX-100 induced small color change. An identification of common anionic surfactants can be accomplished based on a combination of colorimetric pattern of structurally diverse PDAs using principal component analysis technique. Moreover, PDA was successfully fabricated on filter paper and the colorimetric response of PDA coated on filter paper was tested with solution of surfactants and commercial cleaning agent products at various concentrations. These allowed the direct colorimetric detection of anionic surfactants using the paper-based PDA sensor.

title: Adapive discontinuous galerkin method for one-dimensional shallow water equations

description: The Discontinuous Galerkin (DG) method for solving the one-dimensional advection equation and shallow water equations are presented in this thesis. To improve the efficiency of this method, two types of adaptive technique are employed. These are the adaptive polynomial (p-adaptive) and the adaptive mesh (h-adaptive). The main purpose is to improve the accuracy of numerical solution during time integration process. Troubled cells needed to be refined are detected by two types of indicators, which are error and gradient indicators. The present schemes have been applied for solving the advection equation and the standard shallow water equations for both wet bed and dry bed. The moving shock can be detected correctly by the adaptive mesh criteria when the HLL flux approximation is employed at the interface of cell volume.

title: Development of an instructional model to foster learning motivation and learning achievement based on self-efficacy and social cognitive development theories for lower primary students in international schools in Bangkok

description: The objectives of this research were: 1) to develop an instructional model to foster learning motivation and learning achievement based on self-efficacy and social cognitive development theories for lower primary students, and 2) to evaluate the effectiveness of the developed model by implementing it in class. A pilot study was conducted to test the feasibility of the developed model before implementing it to a purposively selected sample of 11 Primary 2 students. The study employed a single group time-series design involving one group of participants and several observations or assessments pertaining to the participants’ mathematics learning before and after the treatment. The participants were taught using the developed procedures over 20 lessons. Their motivation to learn mathematics was measured using Young Children’s Academic Intrinsic Motivation Inventory which had been modified with permission from the author and publisher. Classroom observations and structured interviews were conducted to provide more insights into the participants’ learning behaviour. Their mathematics achievement was measured using the scores obtained on tests following the completion of each lesson unit. The findings of this study were as follow: a)The developed model had seven components as follow: 1) Cordiality: Teacher models warmth, respect, and caring attitude. 2) Collection: Teacher uses a variety of material/tool or opening presentation method to start the lesson. 3) Clarity: Teacher demonstrates to students the steps and procedure involved in solving the task by doing worked examples. 4) Coordination: Teacher provides students with initial tasks that are certain to bring success to the students and provide them practice in applying the procedure. 5) Challenge: Provide options of tasks for students to choose that gives them optimal challenge. 6) Confirmation: Record students’ results in individual file for evaluation of progress, and not compared with other students’ results. 7) Communication: Communicate faith in the students’ ability. Praise them for their effort. Challenge them to do their best. Based on those 7 components, the instructional procedure for use in the classroom is as follow: Teacher creates a positive environment throughout the lesson by i) maintaining a positive ambience where students feel encouraged, accepted and unafraid to try, and ii) communicating faith in the students’ ability and praising their effort and response. The lesson is taught in steps: 1) interest stimulation, 2) clear coordination, 3) individualized challenge, and ends with progress check. b)Results of this study show that the research participants’ motivation in learning mathematics was significantly higher (p≤.05) after the treatment. There was an improvement in their mathematics achievement where the participants achieved test scores higher than the set minimum criteria of 80 percent.

title: In vitro efficacy of alginate-encapsulated saccharomyces cerevisiae against streptococcus agalactiae isolated from nile tilapia

description: Probiotic is a dietary supplement that has been used in tilapia culture. In this study the microencapsulation technique was applied to improve the viability of probiotic during storage and unflavored condition. The probiotic, Saccharomyces cerevisiae were mixed with Peptone dilution saline (group A) or 10% skim milk (group B), encapsulated with alginate via extrusion method and freeze-dried. The viability of group B after being freeze-dried was significantly higher than group A. At 7 and 14 days after being kept in room temperature, the viability of group B was higher than group A. The morphologies of the two groups of microencapsules were round to oval in shape. Group A had rough with concave polygonal ridges surface while group B had rough surface. The survival percent of both groups were higher than the control group after being exposed to NSS pH 1.5 for 1, 2, 3, and 4 h and group B was higher than group A. The survival percent of group B after being exposed to 10% tilapia bile salts was significantly higher than the control group and group A in 1, 2 and 3h. The survival percent of group A was lower than group B, but higher than the control group in every hour of exposer to 10% tilapia bile salts. Free S. cerevisiae, group A and group B had similar antimicrobial activity to 17 from 25 strains of Streptococcus agalactiae. All the results have suggested that the encapsulation of S. cerevisiae with alginate can improve the viability during freeze-drying and storage. Moreover, it can also confer the effect of protection in acid and bile environment.

title: Stick Insect Locomotion

description: The whole-body movements of unrestrained walking and climbing stick insects were measured by marker-based motion-capturing: markers were attached to the body of the insect and tracked by an infrared camera system (Vicon MX10 equipped with 8 T10 cameras). The measured marker trajectories (time-ordered xyz-coordinates) were used to reconstruct the trajectories of various joint locations of the insect, and to calculate the joint angle time courses for all six legs, three thorax segments and the head. The example data provided here is part of a data set comprising several hours of locomotion sequences from three different stick insect species (Carausius morosus, Aretaon asperrimus, Medauroidea extradentata = Cuniculina impigra). Joint angle time courses and footfall patterns have been calculated from the trajectory data. Contains: * Matlab Files from 36 trials, containing original measurements, processed data (e.g., kinematic variables calculated, and metadata). * Sets of overview figures for each trial in one pdf file. * Pairs of videos per trial, showing the side view of a part of the experimental setup, and the whole sequence of recorded marker trajectories. * Motion capture data in bvh format

title: The meditation system of the supreme patriarch suk kaithuean as a living tradition at Wat Ratchasittharam

description: This study aims to examine the history and practice of the Matchima meditation system. It is a system believed to have been passed down by the fourth Supreme Patriarch of the Bangkok era, the Venerable Suk, when he was the abbot at Wat Ratchasittharam. The secondary aim is to explore the differences and commonalities between the manuscript, which the Venerable Suk had inherited and based his teachings on, and the living tradition now taught at the temple. To obtain a holistic understanding of the meditation system as a living tradition, this thesis examines it from five different facets; physical space, perceptions of history, philosophy, pedagogical methods and the perspectives of the practitioners. To achieve this, the researcher made himself a participant of the meditation system by becoming a disciple of the main instructor, Luang Pho Wira. Field research also included an examination into temple publications, the layout and material culture in the temple surroundings, one-on-one interviews with practitioners and the distribution of questionnaires. Besides fieldwork on the temple grounds, literary research into academic and theological literature was conducted with the aims of developing an insight into three subject areas necessary in developing the arguments for this thesis. Firstly, gathering information about contemporary Buddhist meditation movements in Thailand so as to understand their common appeal in present day Thai society and their common features. Secondly, examining the notion of monolithic Theravāda Buddhism and how this notion is not relevant when used to analyze the transmission of meditation teachings. Thirdly, understanding the concept of the Yogāvacara tradition- an ancient tradition of esoteric meditation teachings in Mainland Southeast Asia and how the Venerable Suk’s manuscript fits into this tradition. Based on the data collected and analyzed, the thesis argues that that the Matchima meditation system, which can be considered part of the ancient Yogāvacara tradition, had evolved over time to fit the needs of a changing Thai society. However, despite its adaptation, it still retains certain esoteric practices that set it apart from contemporary meditation systems. I also claim that despite popular conceptions of a monolithic and inflexible Theravāda Buddhism that was believed to have been established since the fourth reign, the Matchima meditation system represents an aspect of Theravāda spiritual practice that is constantly evolving, adapting itself and has even contributed to the rise of other traditions. This proves that Theravāda Buddhism, when viewed from a different lens is actually more flexible, dynamic and multifaceted than previously conceived.

title: Role of dna methylation at herv sequence in systemic lupus erythematosus

description: Previous studies reported that T cells from active SLE patients contained globally hypomethylation and demethylation at promoter of several genes which contributed to disease pathogenesis. So far there is limited information about methylation profile of retroelements in SLE. In this study, we examined and compared the methylation levels of LINE-1, Alu, HERV-E and HERV-K in normal and SLE CD4+ T lymphocytes, CD8+ T lymphocytes and B lymphocytes. Hypomethylation of LINE-1 but not Alu was found in CD4+ T lymphocytes, CD8+ T lymphocytes, and B lymphocytes of SLE patient. Strikingly, LINE-1 hypomethylation was more significantly distinguished in both CD4+ and CD8+ T lymphocytes of patients from the active SLE group. For LTR retroelements, hypomethylation of HERV-E LTR2C was observed in CD4+ T cells of active SLE. Moreover, the hypomethylation of HERV-E LTR2C was correlated with leucopenia and lymphopenia in active SLE while the hypomethylation of HERV-K LTR5_Hs in CD3+CD4+ T cells was significantly correlated with complement activity and SLEDAI score. From comprehensive analysis of genome and gene expression array, IFN-induced genes showed up-regulation in methylation sensitive gene in CD4+ T cells of SLE. However, hypomethylation at promoter region and containing of LINE-1 within gene does not explain this up-regulation. In conclusion, the hypomethylation in each lymphocyte subset of SLE was interspersed repetitive sequences (IRSs) type-specific. We also provided an evidence to propose consequence mechanism of LINE-1 hypomethylation in SLE that LINE-1 transcripts might have an effect in trans to up-regulate the IFN-induced gene. Further study to find out the functional role of IRSs hypomethylation might lead to the discovery of novel pathogenesis pathway in SLE.

title: Fabrication of porous silicon nitride specimen via carbothermal reduction and nitridation of cabonized rf/silica composite

description: Introduction of silica into RF solution, which was prepared via the sol-gel polycondensation of resorcinol and formaldehyde using sodium carbonate as catalyst, was studied. 3-Aminopropyl trimethoxysilane (APTMS) was used as silica precursor. The reaction between RF solution and silica precursor is violent and extremely exothermic which results in rapid solidification of the mixture. To slow down the reaction, and to increase the amount of the silica precursor in the reaction, the reduction of temperature of RF gel and the addition of acetic acid, as inhibitor, in RF gel were used. After aging of the silica/RF gel for 72 hours, t-butanol was used in the solvent exchange process for 24 hours and repeated for 3 times. Then the sample was splitted into two parts for each drying process, i.e. convectional air drying at 110°C and freeze drying processes at -40°C. Next, the silica/RF composite was pyrolyzed under nitrogen gas to convert the RF structure into porous silica/carbon composite. Finally, the obtained product, i.e., porous silicon nitride, was obtained via carbothermal reduction and nitridation at 1450°C for 10 hours followed by the removal of excess carbon by calcination at 800°C for 8 hours. From the results, acetic acid could retard the reaction between RF gel and silica precursor because it breaks cross-linking network within RF gel, which prolongs the gelation time of the composite. However, the higher the acetic acid content is, the lower the composite porosity becomes. Without the addition of acetic acid, the composite became fragile and could not be formed into solid specimen. Aging of RF gel at low temperature also allowed more silica precursor to be added to the composite, because of the decrease in the polymerization reaction between RF and silica. Similarly, for the use of pre-formed silica sol, the silica became sol before being added into RF sol so that, the reaction was less violent.

title: Application of genetic algorithm in well placement for waterflooding

description: Well placement is very important in waterflooding process. A good arrangement of well location does not only increase oil recovery but also reduces the time required to produce the oil. Either vertical or horizontal injectors can be used in this process. This thesis studies application of genetic algorithm in well placement for waterflooding process. A reservoir simulator coupled with genetic algorithm is used to find well locations for each case. The well locations depend on several parameters such as length of well, injection rate, and reservoir thickness. These parameters are varied in order to find the most suitable location. In this study, the scenario to obtain the highest recovery for each reservoir thickness is different. In case of a large reservoir thickness (more than 100 ft), the oil recovery is the highest when using a single vertical producer with two horizontal injectors at injection rate of 10,000 STB/D. This scenario provides high oil recovery and low water production. The production time required to produce oil is less than other scenarios. Although a single vertical producer with two horizontal injectors result in the highest oil recovery for a thick reservoir, this scenario is not suitable for a thin reservoir due to an early breakthrough. A large amount of produced water is turned out. For thin reservoirs, using one horizontal producer with two horizontal injectors with injection rate of 10,000 STB/D is the best choice.

title: Carbon monolith from rf gels and lignocellulosic materials from agricultural wastes

description: In this work, the dissolution and regeneration of lignocellulosic residues from agricultural wastes have been studied. First, the optimal condition of a solvent (NaOH/H2O2) for dissolving lignocellulosic residues (rice straw, kapok, luffa and betel palm) has been investigated. Furthermore, all lignocellulosic solutions are regenerated with 2 M H2SO4. The regeneration of the lignocellulosic solution from betel palm fiber yields the most lignocellulosic material (LCM). The fractions of the obtained lignocellulosic material are 34.51% of lignin and 65.39% of hemicelluloses. Besides, the lignocellulosic material from betel palm fiber is used to prepare carbon gels by mixing with resorcinol-formaldehyde (RF) and the carbon monoliths are obtained by carbonization with N2.This work focuses on the effect of lignin, hemicelluloses and lignocellulosic material as well as the initial pH of mixed gel solutions on porous properties and pore structure of carbon monolith. The comparison of the porous properties and pore structure of carbon monolith prepared from RF-lignocellulosic material gels (C-LCM) and RF-lignin-hemicellulose gels (C-LH) is investigated. Moreover, carbon monoliths prepared from RF-lignin gels (C-L) and RF-hemicellulose gels (C-H) have also been studied. The nitrogen adsorption-desorption results show that addition of lignin can lead to increasing SBET and total pore volume of carbon monoliths (from 333 m2/g to 482 m2/g and from 0.23 m3/g to 0.98 m3/g, respectively). In addition, the porous structure of carbon monolith prepared from RF can be varied from microporous to mesoporous structure when lignin is added to RF (for C-L 4:1). Furthermore, it was found that the initial pH has an effect on cross-linking between lignin and RF as well as the diameter of the nodules on the structure of carbon monolith. This meso-/microporous carbon monolith preparation is more convenient than other methods such as using a hard template of inorganic material and etc. Hence, this work will provide a promising way to use natural resources as a raw material to prepare the hierarchical carbon monoliths.
