title: Effect of Cr, Ni, Cu and Zn in clinker on physical properties of cement via co-processing in a pilot-scale rotary cement kiln

description: Co-processing of industrial wastes in cement kiln can be used for both destruction of hazardous organics and stabilization of heavy metals. This method provides a management option to use the wastes as raw materials or fuel in cement production. However, heavy metals in the wastes may adversely affect cement properties. This study investigated chemical and physical characteristics of various mixtures of heavy metals in synthetic raw materials to produce cement clinkers. Raw materials were mixed with different ratios of single oxide of heavy metals: namely, chromium oxides (Cr₂O₃), copper oxides (CuO), nickel oxides (NiO₂), zinc oxide (ZnO), and the two combinations of four kinds of heavy metals, i.e. 0.05%, 0.3%, 0.5%, 1.0% and 2.0%. The mixtures of Ordinary Portland Cement Type I were burned in a pilot-scale rotary cement kiln which the liquefied petroleum gas was used as fuel. Results showed that concentrations of heavy metals in the clinkers were higher than those in the mixtures before combustion. Moreover, the heavy metals were not destroyed in the burning process and they were found in the clinker associated with main phases of clinker, C₂S, C₃S, C₃A and C₄AF. High concentrations of heavy metals caused increase in free lime content, but decrease in C₃S. In particular, Cr and Cu concentrations greater than 1.0% by weight were produced more than 1.5% of free lime and caused unacceptable compressive strengths. Increase in Ni and Zn concentrations caused free lime contents to increase slightly although they were still within the SCCC’s quality standard of 1.5%. However, the mortars with higher Ni and Zn contents produced better compressive strength values than the standard values. Improvement of early strength at 1 day for 0.05%, 0.1%, 0.1% and 0.5% by weight of combination of heavy metals, Cu, Zn and Ni, respectively, were more than 130 kg cm⁻². The 28-day compressive strength values of clinkers containing 0.05-0.3%, 0.1%, 0.5% and 1.0% by weight of combination of heavy metals, Cu, Ni and Zn respectively, were more than 400 kg cm⁻². As for environmental impact evaluations, Waste Extraction Tests showed that heavy metal concentrations in leachates of all of the different ratios of heavy metals in clinker and cement mortar did not exceed the Thai regulatory standards (Cr, Cu, Ni and Zn less than 5, 25, 20 and 250 ppm respectively)

title: Production of biosurfactant by Achromobacter sp. GY30 from waste glycerol and potential application for vegetable oil extraction

description: Vegetable oil is commonly extracted from oilseeds by solvent extraction with hexane. However, hexane is volatile and toxic to human and environment. To reduce the use of hexane, alternative methods of oil extraction have been developed such as aqueous extraction process (AEP). Nevertheless, AEP by using water alone has low oil extraction efficiency. Biosurfactant can be used to improve the oil extraction yield in AEP. Although the use of biosurfactants has been increasing over the year, their large scale production and application are limited with high production cost and low productivity. In this study, an effective biosurfant-producing bacterium was isolated and selected for investigated their optimum medium composition and examined for their potential application in vegetable oil extraction. Achromobacter sp. GY30 which produced low surface and interfacial tension of medium, high E₂₄ (%) with vegetable oil, and high oil detachment (%), was selected as an effective biosurfactant-producing bacterium. Strain GY30 was then determined for its optimum culture medium composition for biosurfactant production. The parameters affected biosurfactant production; waste glycerol concentration, nitrogen source and concentration, C/N ratio, and precursor supplementation, were evaluated by using classical method (study one factor at a time) and experimental design. From using the classical method, increasing biosurfactant yield of 2 fold was observed when using 5% (w/v) waste glycerol, 0.4% (w/v) NaNO₃, and supplemented with 0.1% (v/v) palm oil. The best culture medium composition of 7% (w/v) waste glycerol, 0.4% (w/v) NaNO₃, and supplemented with 0.01% (v/v) palm oil, correlated to C/N ratio of 42, was obtained when using experimental design. It produced high biosurfactant yield of 0.79 (g/l). Moreover, it could enhance productivity 20% from the previous experiment. Then, the potential application of biosurfactant from strain GY30 in vegetable oil extraction was studied. The highest oil detachment of 60% was obtained when using cell-free broth. In addition, it was found that isolated biosurfactant solution could extract palm kernel oil in free oil form which is favorable in the oil extraction process. For free fatty acid content, it was found that extracted oil from this method was comparable to those of the hexane method and much better than those of mechanical pressing. Thus, the use of isolated biosurfactant in aqueous-based method for palm kernel oil extraction was of the interest alternative method for reducing the use of hexane.

title: The behavior of Thai consumers on Korean-styled rhinoplasty surgery in Thai aesthetic clinics

description: To study (1) the relationship between Korean wave and Korean-styled rhinoplasty trend in Thailand (2) the factors that influence the booming of Korean-styled aesthetic clinics in Thailand (3) the consumer’s behaviors on consuming these kinds of service and the possible effect. For the part of the qualitative data, the analysis was processed from the history data of this trend and from the in-depth interviews of Thai consumers with various attitudes towards rhinoplasty. Additionally, the quantitative data was achieved from the 130 sets of questionnaires. The result shows the most influential factors which are the indicators of behavior and attitude of Thai consumers in both natural and business purposes, are the usage of media and the marketing strategy concerning Korean wave. However, for Thailand, the outcome from this trend is still unsuccessful because of the fact that most Thai consumers have the anti or negative attitude about cosmetic surgery, and also we are still lack of support from Thai government to promote this private business as Korean government.

title: Comparison of species diversity and abundance of ants in grassland and reforestation area at Lai Nan sub district, Wiang Sa district, Nan province

description: Grassland is a community with specific composition of living organisms. Nowadays, grasslands are used extensively by human activities that cause various effects on living organisms. This research were to investigate and compare the diversity and abundance of ants between in grassland and reforestation area at Lai Nan Sub-district, Wiang Sa district, Nan province. Six sampling methods: hand capture with constant time, sugar baiting trap, protein baiting trap, pitfall trap, leaf litter sifting, and soil sifting, were conducted monthly in the two study areas from June 2010 to June 2011. The overall species richness of ants was 34 species (23 species and 11 morpho-species) from 22 genera in six subfamilies. The Shannon Weiner species diversity index indicated that the diversity was higher in reforestation area (0.65) than in grassland (0.62). The diversity of ants werenot different between the two study areas from the high Sorensen’s similarity coefficient (92%). Besides different habitats, the environmental fluctuations due to seasonal factors also affected the variation of ants. The Sorensen’s similarity coefficient between wet and dry seasons in two study areas among seasons were 84-91%. The pattern of ant diversity showed that the two study areas were not different between the habitat and season. The first four highest abundant ants, three species were significantly correlated with some physical factors in two study areas. Afterwards, all collected ants were classified into six functional groups as Dominant Dolichoderinae, SubordinatCamponotini, Climate Specialists, Cryptic Specialists, Generalized Myrmicinae, and Specialists Predators. Both Climate Specialist and Cryptic Specialists were dominated in reforestation areabut not in grassland. Accordingly, ants could be used as indicators for monitoring changes of the disturbance habitat as well.

title: Extraction and antioxidant properties of propolis from China, Korea and Northern Thailand

description: The main goal of this investigation is to determine the main flavonoid which is the main activity of Thai propolis by using spectrophotometric method and high-performance liquid chromatography (HPLC). Additionally, the antioxidant and antimicrobial activity of the propolis from different location in China, Korea and Northern Thailand are also determinated. The result shows that the total flavonoids in all 17 propolis from the different geographic locationin Thailand are lower than 2% and lower than the propolis samples from UK, Korea, Brazil and China. However, one sample (CM1) from Chiang Mai province of Thailand is higher (13.34%) and closer to the other countries. The contents of 8 major flavonoids in Thailand propolis are as follows:rutin ranges (w/w) 0.01–0. 28%, myricetin 0.00–0.08%, quercetin 0.00–0.92%, kaempferol 0.00–0.36% , apigenin 0.00–0.25%, pinocembrine 0.00–0.09%, chrysin 0.00–1.81% and galangin 0.00–1.81%. Only one propolis sample ( CM1 ) from Chiang Maiidentified all 8 main flavonoids, rutin(0.06%), myricetin (0.08%), quercetin (0.92%), kaempferol (0.36%), apigenin (0.25%), pinocembrine (0.01%), chrysin (1.81%) and galangin (1.81%), and had many peaks in the HPLC figure.The antioxidant activity test showed that propolis had a strong reducing power and strong DPPH radical scavenging activity, indicating that the antioxidant activity of the propolis samples from Chiang Mai (CM), Chinag Rai (CR), Lamphun (LP) and Nan (N) of Thailand were all good. The result of study on MIC50 from various propolis extracts against Staphylococcus aureus. demonstrates that all the propolis extracts show the antimicrobial effect to Staphylococcus aureus, the sequence from low to high of MIC50 against S.aureus is Brazil

title: Factors affecting photobook preferences of young Thai

description: This research attempted to find out which factors affecting photobook preferences of young Thai and to understand how the print quality parameters affected perceived image of photobook and how this perception changed as a function of a Thai customers' preference. A group of participants, 17-24 years old, were asked to express their feelings about photobook products and to indicate the acceptability of factors, which influence the decision to make photobook. These participants represented the young Thai whose hobbies are mostly related to IT (information technology). Results based on weighted arithmetic Mean showed that print quality of printed images and design of photobook were the prior factors affecting the preference of these people. In addition, individuals viewed and provided rating information of quality parameters of print samples made from 5 print shops with varying high-end printers. The survey data were analyzed by Analysis Hierarchy Process (AHP) technique, by which loading factors, ranging 0-1, relevant to young Thai' preference regarding print quality parameters were obtained. Print quality preference equation thus could be established. Results showed that the preference equation could predict the preference of the young Thai by observation.

title: Method development for determination of ferulic acid by lab-on-paper

description: In this research, the method to determine ferulic acid using lab-on-paper coupled with the colorimetric detection was developed. The colorimetric reaction between ferulic acid, folin phenol reagent, and sodium carbonate solution provided the blue color. The intensity of the color depended on the concentration of ferulic acid. The limit of detection (LOD) was found to be 7.19 ppm. The limit of quantification (LOQ) was found to be 23.98 ppm. Linear region between mean intensity and the concentration of ferulic acid was observed with a good coefficient of 0.9974. To compare the determination of ferulic acid between the lab-on-paper technique and high performance liquid chromatography, the results shows that the determination of ferulic acid by lab-on-paper is simple, fast, and non-toxic. In addition, lab-on-paper was applied to detect ferulic acid in cosmetic effectively.

title: Replication data for: Intergroup Conflict and Intra-group Punishment in an Experimental Contest Game

description: We study how conflict in contest games is influenced by rival parties being groups and by group members being able to punish each other. Our motivation stems from the analysis of sociopolitical conflict. The theoretical prediction is that conflict expenditures are independent of group size and of whether punishment is available. We find, first, that conflict expenditures of groups are substantially larger than those of individuals, and both are above equilibrium. Second, allowing group members to punish each other leads to even larger conflict expenditures. These results contrast with those from public goods experiments where punishment enhances efficiency.

title: Replication data for: Monetary Policy Rules and Macroeconomic Stability: Some New Evidence

description: I revisit the question of indeterminacy in US monetary policy using limited-information identification-robust methods. I find that the conclusions of Clarida, Galí, and Gernter (2000) that policy was inactive before 1979 are robust, but the evidence over the Volcker-Greenspan periods is inconclusive. I show that this is in fact consistent with policy being active over that period. Problems of identification also arise because policy reaction has been more gradual recently. At a methodological level, the paper demonstrates that identification issues should be taken seriously, and that identification-robust methods can be informative even when they produce wide confidence sets.

title: Replication data for: Tournaments and Office Politics: Evidence from a Real Effort Experiment

description: Tournaments can elicit more effort but sabotage may attenuate the effect of competition. Because it is hard to separate effort and ability, the evidence on tournaments is thin. There is even less evidence on sabotage because these acts often consist of subjective peer evaluation or "office politics." We discuss real effort experiments in which quality adjusted output and office politics are compared under piece rates and tournaments and find that tournaments increase effort only in the absence of office politics. Competitors subvert each other more in tournaments, and as a result, workers produce less because they expect to be sabotaged. (D82, M54)

title: Determinants of Korean consumer’s behavior in purchasing luxury brand name products

description: The objective of this study is to identify the important factors that lead to Koreans’ purchase on luxury brand products. This study also suggests the strategy for developing campaign promoting the sale of luxury brand products. This study collected data from 359 Korean people, aged between 20-30 years old in Sin-Chon neighborhood, Seoul, South Korea, during March – April, 2012. Out of 400 questionnaires that have been distributed to the respondents, 359 questionnaires (89.75%) were received. Descriptive statistic is used in this study.The results show that most of the respondents are female, ag 18-20 years old. Top item is hand bag and top brand is MCM that is originally a German luxury brand but now resurrection by Korean. Moreover, the results show that the important factors that lead Korean consumers to purchase luxury brand products the most is self-identity value, followed by quality value and usability value. Korean purchasing decision has evolved over time. Korean consumers do not purchase luxury brand name products because they want to show off like in the past, but they move forward to the fit in stage. This is when consumers decide to buy luxury products because they want to belong in the society. For the strategy for developing campaign on luxury brand product that suit with the young Korean consumers, except from items that have high quality, look good, last long and perform as they expected, we suggest by focusing on the presenters of the brand. Presenters should have many characters to suit with the style of the consumers, which will help them show their style through that product and want to support that brand. We suggest that the companies should be adjusted to match with behavior of their target group according to age group, income level and gender aspects.
