title: Wallrock alteration and mineralization of the A and the H West prospects, Chatree gold deposit, Changwat Phichit and Phetchabun, Thailand

description: The Chatree Gold mine is presently the major gold deposit in Thailand located about 280 km north of Bangkok, on the border of Phetchabun and Pichit Provinces. This study was focussed mainly on wall rock alteration in relation to mineralization of the A and the H West Prospects. Even though many workers have previously studied on mineralization and wall rock alteration on these Prospects, those studies are still considered sporadic or focused on small areas, particularly on the wall rock alteration, of those Prospects. This study is therefore aimed at systematically characterizing in more details on the host rock alteration in relation to the mineralization by using staining technique, standard petrographic studies of thin sections, polish sections and polish thin sections in combination with electron probe microanalysis of altered and ore minerals. The rock units in the Chatree gold deposit comprise 4 units as Unit 1: fiamme breccias, Unit 2: epiclastic and fine volcaniclastic sedimentary facies and rhyolite breccia facies, Unit 3: polymictic and Monomict ic andesite breccia, and Unit 4: andesite porphyry. The A Prospect is reported only Units 1 to 3 while the lowest unit (Unit 4) is omitted due to the insufficient depth of drilled holes. The H West Prospect consists of three units as Unit 1, Unit 3, and Unit 4, while the volcaniclastics of Unit 2 is absent in this area. Based on previous and this studies, the A and H West Prospects possess similar nature of mineralization and six vein stages have been identified in these two Prospects, namely. Stage I: gray chalcedony, Stage II: quartz–euhedral pyrite, Stage III: major gold mineralization, Stage IV: quartz–carbonate±prehnite veinlets, Stage V: non-ferroan calcite veinlets, and Stage VI: laumontite. The A and H West Prospects comprise several mineral alteration halo, including silicification, potassic, and phyllic alterations that are proximal to the veins, whereas propyritic alteration is distal from the veins. The alteration minerals selectively replaced in the vein host rocks. The silicification was related to the Stage I mineralization. The gold-bearing Stage III mineralization was related to the potassic alteration proximal to the ore zone, while sericite±quartz or phyllic alteration was found next away from the ore zone in the Stage IV mineralization. Chlorite or porpylitic alteration was found distal to the ore zone in the Stages III-V. The late carbonate is assumed to occur in the stage V. The alteration halos in the H West Prospect are rather narrow (normally about 1-2 mm scale or may be up to 20 cm wide around veins system) as compared with those found in the A Prospect (normally 5 – 30 m scale).

title: A content analysis of theses related to Korean studies in Thailand during 1988-2009

description: The objectives of this research was to study the interest of graduated students theses related to Korean Studies in Thailand in forms of Thesis , graduated Thesis , thematic of paper ,term paper and independent study of the graduate students. The studied theses are from both public and private universities in Thailand during 1988-2009 from 15 universities. The research methodology is to study the documents and to collect the theses from various sources. The data were then analyzed in terms of frequency distribution and percentage in form of tables; categorized by the academic institutions and the year of research, fields of study, the content, summary, and the findings of research. The quantitative study found that from 90 issues, most theses were published by Chulalongkorn University. The research topic mainly focuses on the international relations, law, and the influence of Korean culture to the Thai’s society. The qualitative research showed that the graduate students studying Korean Studies in Thailand did not only because the Korean trend, but they studied of the situations relate to Korea, especially the ones that Thailand has been involved with. The students linked these situations with the knowledge of their own fields of study .From the analysis yielded that Thailand has closer relationship with South Korea more than with North Korea, especially in terms of trade-investment, tourism, and culture. With the Korean entertainment culture, it is known as Korean wave that influencing over the Thai’s society for example, Korean series, and Korean Stars. This has caused the imitating behavior among Thai people such as costume fashion. Moreover, this helps spread the Korean food and Korean language to be more well-known including the desire to travel in South Korea. On contrary, for the South Korean products were not as popular as expected during the year of study compared to the culture in Thailand. It is because of the quality and the satisfaction of the previous products with the use of inappropriate marketing media of Korean products. Thus, it was unable to reach many of Thai consumers, electroacoutics and cosmetics products in particular

title: The Cosmogrid Simulation: Statistical Properties of Small Dark Matter Halos (2048-178)

description: We present the results of the "Cosmogrid" cosmological N-body simulation suites based on the concordance LCDM model. The Cosmogrid simulation was performed in a 30 Mpc box with 2048³ particles. The mass of each particle is 1.28x10^5 Msun, which is sufficient to resolve ultra-faint dwarfs. We found that the halo mass function shows good agreement with the Sheth & Tormen fitting function down to ~10^7 Msun. We have analyzed the spherically averaged density profiles of the three most massive halos which are of galaxy group size and contain at least 170 million particles. The slopes of these density profiles become shallower than -1 at the inner most radius. We also find a clear correlation of halo concentration with mass. The mass dependence of the concentration parameter cannot be expressed by a single power law, however a simple model based on the Press-Schechter theory proposed by Navarro et al. gives reasonable agreement with this dependence. The spin parameter does not show a correlation with the halo mass. The probability distribution functions for both concentration and spin are well fitted by the log-normal distribution for halos with the masses larger than ~10^8 Msun. The subhalo abundance depends on the halo mass. Galaxy-sized halos have 50% more subhalos than ~10^11 Msun halos have. This is snapshot 178 of the 2048³ resolution collection.

title: Enantiomeric separation of flavonoid compounds using capillary electrokinetic chromatography

description: Simultaneous separation of 2'- 4'- and 7-hydroxyflavanone enantiomers was investigated using cyclodextrin-electrokinetic chromatography (CD-EKC) with single or dual highly sulfated-CD (HS-β-CD and/or HS-γ-CD in a pH 2.5 phosphate buffer. Enantioselectivity (к) defined as the ratio of the binding constant к for enantiomers to CD, was obtained in order 2'- &gt; 4'- ≈ 7- with HS-β-CD (3.16, 1.04 and 1.02, respectively) while 4'- &gt; 2'- &gt; 7- with HS-y-CD (1.40, 1.17, and 1.09 respectively). The optimum enantiomeric resolution (Rs) was found to be consistent with the к scale: very high Rs, up to 19 for 2'- with HS-β-CD, partial Rs for 4'- and 7- with HS-β-CD, and achieved baseline Rs ≥ 1.5 for simultaneous separation of these three enantiomers with HSγ-CD. In dual CDs using the fixed concentration of CD1 (4 or 8 mM HS-β-CD) and varying the concentration of CD2 (2 to 47 mM HS-γ-CD), a change in separation selectivity (α), defined as the ratio of the electrophoretic mobilities for enantiomers, with an increase in the CD2 concentration was found to be consistent with the concept of dual enantioselectivities for dual CDs: an increase in α for 7- due to the same order of enantiomers in CD2 and CD2 with к2 &gt; α1, a decrease in α for 2'- due to the same order of enantiomers in CD2 and CD1 with к2 &lt; к1, while a decrease in α to 1.0 and then an increase in α at higher CD2 for 4'- due to the reversed migration order of enantiomers in CD2 and CD1 with к2 &gt; к1.

title: Effect of nanoscale zero-valent iron (NZVI) on bacterial viability : roles of growth phases and oxidative stress

description: The effect of nanosale zero-valent iron (nZVI) particles on bacteria from different growth phases was studied. Four acterial strans including Escherichia coli strains JM109 and BW25113, and Pseudomonas putida strains KT2440 and F1 were experimented. The growth characteristics of these strains were determined. Their cells were harvested based on predetermined time points corresponding to different growth phases and exposed to nZVI. The cell viability was determined by a plate count method. The cells in lag and exponential phases showed higher resistance to nZVI for all four bacterial strains, whereas the cells in exponential and decline phases were ess resistant and were rapidly inactivated when exposed to nZVI. Bacterial inactivation increased with the concentration of nZVI. Furthermore, less than 14% reducton in viability was observed when the cells were exposed to the leachate of nZVI suspension suggesting that the physical interaction between nZVI and the cells is critical for bacteria inactivation. The responses from various oxidative stress gene knockout strains of E. coli BW25113 to nZVI were examined. For each of these mutant strains, cells from different growth phases were collected and exposed to nZVI. The vibility of the cells was determined by a plate count method. All of the mutant strains exhibited higher susceptibility to nZVI when compared to the wild type strain. The results also indicated that different knockout strains exhibited different levels of susceptibility to nZVI. Strain lacking RpoS, a global stress regulator, showed the highest susceptibility. Among different defensive enzymes mutants, sodA and sodB mutants exhibited the highest vulnerability whereas sodC mutant revealed much less susceptibility suggesting that nZVI may induce oxidative stress inside the cels via superoxide generation. The inducibility of catalase (hydroperoxidase I) was also investigated by exposing the cells to nZVI and measuring a related gene expression using quantitative polymerase chain reaction. Result suggested that nZVI repressed the expression of this enzyme.

title: Applying virus technology in audio protection mechanism

description: Internet is a global system of interconnected computer networks that helps users reach to all digital data, such as multimedia files. So, this leads to plagiarization, violation of copyrights and data over the Internet. Thus, the digital intellectual property becomes a big issue of the Internet sharing system. Various techniques have been proposed to protect these violations; unfortunately, they became the hackers’ stimuli in breaking the protection mechanisms. Therefore, this thesis proposes a protection mechanism, Byte Encoding Protection (BENPro), for preventing an audio file, such as mp3 format from copying and distributing by illegal distributors. The aim of this thesis is that the protection mechanism cannot be recognized from hackers and users. The result of this experiment indicates that most users believe that the defects occur from the transfer mechanism rather than the protection mechanism. Thus, the protection of IP is maintained as expected.

title: Pre-feasibility study of carbon capture and storage (CCS) technologies : a case study of offshore natural gas field in Thailand

description: Carbon dioxide capture and storage (CCS) has played more roles in greenhouse gas (GHG) reduction while the Kyoto Protocol sets targets for each nation to reduce its emission of CO2 and reduce investment cost of reduction between developed country and developing country by using Clean Development Mechanism (CDM). In this study, CCS systems are speciﬁcally designed to remove CO2 from the natural gas production and safely store the CO2 in deplete gas reservoir. Inclusion of CCS in the CDM could be a way to provide an incentive to those CCS project types that are ready to be deployed commercially. A case study on natural gas field produces natural gas approximately 350 MMSCF per day which contains 28-32 percent of CO2. In order to meet sale specification, company has to reduce CO2 to 23 percent before delivery. The process leads to emit great amount of CO2 annually so the technical and economic feasibility of CCS is being studied. An efficient model was developed to predict the economics involved in the CCS projects. The model mainly consists of Discounted Cash Flow Analysis and Monte Carlo Simulation to determine uncertainties of the project which is composed of capital cost of construction, operating cost and carbon credits. From the study, the CCS project able to achieve significant reduction in GHG emissions approximately 850,000 tons per year. Inclusion of CCS project in the CDM can provide an important incentive for potential investment in the project. This incentive could offset the incremental cost of the technology however the project itself cannot achieve in CCS technology without carbon credit support. Nevertheless, the current price of carbon credit cannot induce the company to invest in CCS as well

title: Effect of media on stock returns in Thailand

description: It has been empirically confirmed that media has a significant effect on the stock market. Mass media can alleviate information symmetry as well as informational frictions to a certain extent and affect security pricing even if it does not provide genuine news. Thepaper investigates this hypothesis by empirically studying the effect of media coverage onstock returns. Using non-regression and regression approaches, this paper also hopes to contribute to the expanding research within specific geographical region by investigating Thai data and examining the media effect in Thai stock market. The media effect found in the non-regression approach is a total opposite to the regression approach. However, the regression approach provides a stronger evidence to the media effect, as risk factors such as market, size and book-to-market factors are properly captured and controlled in CAPM and Fama-French three-factor model. It is found that using a media trading strategy that takes along position on stocks with low media coverage and short position on stocks with high media coverage, stocks with high media coverage outperform stocks with low mediacoverage, even after controlling for firm characteristics such as size and book-to-market ratios. The result is a total opposite to the media effect found in the U.S.
