title: Diversity of ferns and fern allies at Khao Khiao area in Khao Yai National Park

description: Diversity of pteridophyte at Khao Khiao, Khao Yai National Park was explored from December 2003 to May 2005 at elevations ranging from 600 to 1,300 m above mean sea level. Two hundred and nineteen specimens were collected from their natural habitats and were determined into 113 species and 2 varieties, in 59 genera within 25 families. Among these, 22 families, 55 genera, 105 species and 2 varieties were ferns, while 3 familes, 4 genera and 8 species were fern allies. Three families of ferns namely, Polypodiaceae, Thelypteridaceae, Dryopteridaceae, were among the common families which included 17, 13 and 12 species, respectively. As regard to habitat, there were 58 species of terrestrials, 30 species of epiphytes and 7 species and 2 varieties of lithophytes. However 18 species of ferns and fern allies could be found in more than one habitat. In addition, it can be concluded that 53 species and 2 varieties were found in tropical evergreen forest. While 34 species were found in hill evergreen forest and 6 species were found in grassland and secondary forest. However, 20 species grew in more than one forest types. Full description together with ecological data, distribution, vernacular name, utilization of and photographs of each species were prepared. Keys to the genera and species were also constructed. The voucher specimens were depsited at the Professor Kasin Suvatabhandhu Herbarium, Department of Botany, Faculty of Science, Chulalongkorn University and The Forest Herbarium, National Park, Wildlife and Plant Conservation Department.

title: Inflationary model within noncommutative space-time

description: It is well known nowadays that the best candidate for the cosmological model is the inflationary model which describes the rapid expansion of the universe at the early time. This inflationary scenario is assumed to take place at a very high energy scale, at which classical general relativity is no longer valid as the quantum effects become more relevant. String theory is the most promising candidate for describing the nature of physics in this scale. The universal property of this theory is the stringy space-time uncertainty relation. The noncommutative property of space and time is the important consequence of this property. The aim of this thesis is to study the inflationary model in which the effect of noncommutative space-time is taken into account. The Cosmic Microwave Background (CMB) power spectrum is the convenient quantity that one uses to compare the result of the model with observed data. The comparison can be divided into two classes according to their vacua, which are the adiabatic vacuum and the minimized uncertainty vacuum. The result of both vacua is consistent that the noncommutative effect suppresses the spectrum at the low multipole. This result is more compatible with observation than the result of the commutative space-time.

title: Separation of carotenoids from palm oil using ag-treated clays

description: To determine the separation condition of carotenoids from palm oil using ag-treated clay as adsorbents in batch system. Clays used in this experiment were bentonites originated from China and Japan. The Ag-treated clays at different ag types and content in various forms (Ag + form, AgO form, AgCl form and Ag form) were prepared. The factors affecting the adsorption step such as type of ag-treated clays, adsorption time, ratio of clay to palm oil and adsorption temperature were studied. Then, factors affecting the desorption step such as type of eluting solvents and desorption temperature were investigated to determine the optimum condition. The study of factors affecting degradation of beta-carotene extraction with antiolxidant (BHT) were studied for improving recovery of carotene from palm oil. Moreover, regeneration of used clay was studied as a mean of environment protection. Results show that the optimum condition for carotene adsorption on o.5% AgCl-treated bentonite from China (2-steps) which was treated with antioxidant (BHT) at a ratio of 1:5 by weight of clay to palm oil, at 60 ํC for 60 minutes could adsorb 86.82% carotene. The suitable condition of carotene desorption from clay was carried out at room temperature by using tetrahydrofuran as an eluting solvent resulted in 75.76% carotene desorption. From the above conditions, overall carotene recovery from crude palm oil corresponding to 65.77% by weight of carotene in crude palm oil.

title: Characterization of some varieties of gemstones by FT-IR spectroscopy

description: A novel transflectance technique using an infrared microscope was introduced for spectral acquisition of loose and mounted faceted gemstones. The transflectance technique exploited total internal reflection phenomenon within the faceted gemstone for the spectral acquisition. The incident radiation is coupled to the gemstone via the table facet while the transflectance radiation is collected by the built-in 15X Cassegrain objective. A novel accessory for adjusting the reflection plane of the faceted gemstone was constructed and was utilized with the infrared microscope. The technique is nondestructive, requires no sample preparation, and has short analysis time. FTIR spectra of faceted gemstones, synthetic gemstones and gemstone simulants collected by diffuse reflectance, specular reflection, and tranflectance techniques were compared. The same spectra features with better spectral quality as those from the well-accepted diffuse reflectance technique are observed by the transflectance technique. Unlike the diffuse reflectance spectra, the transflectance spectrum was not affected by the diamond arrangements. The technique can be employed for direct spectra acquisition of mounted gemstone without taking the gemstone out of the jewelry setting. Moreover, an individual gemstone on the complex jewelry setting can be selectively measured. Infrared absorption bands unique to the chemical compositions, impurities, and treatment processes of the gemstone were discussed. The observed transflectance spectra can be exploited for gems classification.

title: Factors influencing shrinkage of natural rubber/EPDM blend

description: In this research work, various factors influencing the shrinkage of natural rubber/EPDM blends (ratio of 70:30) and the physical properties of vulcanized rubber were studied. The types and concentrations of filler and vulcanization systems were also investigated. It was found that the shrinkage of the clay filled compound was the lowest, while the shrinkage of calcium carbonate filled compound was the highest. The results also showed that the carbon black filled compound and silica filled compound had similar trend. For all vulcanizates, the increased amount of filler resulted in decreasing shrinkage due to the decrease in rubber content. The change of shrinkage was consistent with the linear coefficient of thermal expansion of each filled compound. It was also found that the efficient vulcanized compound shrinkage was lower than semi-efficient and conventional vulcanized compound, respectively. This is due to the fact that the efficient vulcanized compound exhibited the highest crosslink density. The stiff vulcanizates yielded a low shrinkage value.

title: Factors leading to the success in the rehabilitation process : an empirical evidence from the Stock Exchange of Thailand

description: This study provides some empirical evidence about factors leading to the success in the rehabilitation process that rehabco firms - severe financially distressed listed firms in Thailand - must accomlish to avoid the delisting status established by the Stock Exchange of Thailand (SET). The sample in this study consisted of 68 rehabco firms that were classified as 48 successfully rehabilitated firms and 20 unsuccessful ones. Based on the relevant concept and theories - the discounted free cash flow, the agency theory, and the positive accounting theory - the factors of interest in this study consisted of the value creation factors, the good corporate governance improvement factors, and the earnings management factor. After using the binary logistic regression as the statistical analysis technique, this study found that the successful rehabco firms possessed some good recovery prospects - the sales growth, and the success in the troubled debt restructuring, disclosed their corporate information more transparently, and significantly increased the level of discretionary accruals that led to the positive amount of net income, in order to attract the external funds providers and to meet the SET's rehabilitation criteria.

title: Scaleup of an airlift bioreactor for cultivation of diatom, Chaetoceros calcitrans

description: The optimal system configuration for the growth of Chaetoceros calcitrans in the 17 L airlift photobioreactor (ALPBR) was the system with the ratio between downcomer to riser cross sectional areas (A[subscript d] : A[subscript r]) of 2.62. The maximum specific growth rate and the maximum cell concentration were 7.41x10[superscript -2]h[superscript -1] and 8.88x10[superscript 6] cells mL[superscript -1] respectively for the cultivation with gas velocity (U[subscript sg]) of 3 cm S[superscript -1]. The growth of the diatom in the system did not depend on the level of gas-liquid mass transfer, but rather, it was controlled primarily by the light intensity. A few factors were found to have great influence on the growth characteristics. Firstly, the growth of the diatom was limited by the nutrient depletion. The cultivation of the diatom with two fold nutrient concentration increased the final cell concentration, and also the growth of the diatom in the refreshed spent medium resulted in almost the same growth rate and maximum cell concentration as obtained from the batch cultivation. However, the increase in the nutrient concentration could not enhance the growth rate of the diatom. Bubbles shading and self shading effects also affected the growth of the diatom by obstructing the light penetration into the system. The expanded top ALPBR was proposed to deal with the bubble shading effect as this system allowed an effective removal of small bubbles at the liquid surface. It was shown that no bubble shading effect could be seen in this expanded top ALPBR, but only a slight decrease in maximum cell concentration was observed at U[subscript sg] = 5 cm s[superscript -1] as this rather high U[subscript sg] could see an escape of small bubbles into the downcomer and decreasing the light intensity. Self shading effect could be dealt with using the ALPBRs-in-series setup when two or three culturing columns were connected in series. This setup allowed a better light penetration in the first column and confined the region of low light intensity to only the last column. The experiment demonstrated that the growth rate could be enhanced by 24.8% when compared with the conventional ALPBR. The diatom could be cultivated in both semi-continuous modes to ensure higher specific productivity. The analysis revealed that the continuous mode with medium feed rate of 3 mL min[superscript -1] was the most economical choice for the growth of this diatom. The diatom was also cultivated as a mass production in the large scale system. The maximum cell concentration and specific growth rate in the large scale bubble column, concentric ALPBR and multiple draft tubes ALPBR were not significantly different which implied that the effect of airlift inside such large system was only marginal.

title: Putative human enhancers based on ReMap 2018 (hg38)

description: To generate a collection of putative enhancer regions, we collected all transcription factor ChIP-seq peaks from ReMap 2018 (ref remap; http://remap.univ-amu.fr/storage/remap2018/hg38/MACS/remap2018_all_macs2_hg38_v1_2.bed.gz). We took the summit of all peaks and extended these 25 bp up- and downstream. Based on this file, we generated a coverage bedGraph using bedtools genomecov. We performed peak calling on this bedGraph file using bdgpeakcall from MACS2 2.2.7.1, with the following settings: l=50 and g=10. We performed the peak calling twice, setting c to 4 and 30, respectively. All peaks from c=30 were combined with all peaks of c=4 that did not overlap with the peaks of c=30. We then removed all regions on chrM and extended the summit of the peaks 100 bp up- and downstream to generate a final collection of 1,268,775 putative enhancers of 200 bp.

title: Effects of beta-nucleating agent and mineral fillers on mechanical properties of PP/EPR blends

description: The effect of nucleating agents (0.001 wt% bicomponent of calcium stearate and pimelic acid, Ca-Pim, and 0.001 wt% bicomponent of calcium stearate and suberic acid, Ca-Sub) and fillers (kaolin and CaCO[subscript 3]) on beta-crystalline in PP/EPR blend were investigated by WAXD measurement. Results showed that only Ca-Pim promoted Beta-crystalline. For the fillers, it was found that 5-15 wt% of calcium carbonate promoted beta-crystalline and improved tensile and flexural moduli. Therefore, both Ca-Pim and CaCO[subscript 3] were simultaneously added into the PP/EPR blend in order to improve its Izod impact, tensile modulus and flexural modulus. It was found that the composite containing 0.001 wt% Ca-Pim and 5 wt% nano-CaCO[subscript 3] had the highest impact strength and high tensile and flexural moduli. From WAXD measurement, the k-value was about 0.3, higher than that of CaCO[subscript 3] without Ca-Pim. It indicated that both Ca-Pim and CaCO[subscript 3] additively promoted beta-crystallization. The beta-crystalline formation was also confirmed by DSC which exhibited an endothermic melting peak at 153 degree celsius. The effect of isothemal crystallization of Ca-Pim and CaCO[subscript 3] at 130 degree Celsius on beta-crystalline, thermal properties and spherulitic structure was investigated. The results showed k-value of 0.001wt% Ca-Pim and 10 wt% nano-CaCO[subscript 3] wt was 1.0, indicating that beta-crystalline occurred completely.

title: Synthesis of hydroquinones and benzoquinones as antioxidants in lubricant

description: Twenty one 2-alkylated hydroquinones (H1-H21) and four 2-alkylated-1,4-benzoquinones (Q1-Q4) were synthesized, characterized and explored for their antioxidant activity in lubricant. Among those synthesized compounds, nine hydroquinones (H3, H6-H8, H11-H13, H16 and H20) and a benzoquinones (Q3) were disclosed to be new compounds. The preliminary antioxidant activity results by DPPH radical scavenging assay pointed out that all synthesized hydroquinones exhibited high activity against scavenging DPPH radicals. Three new hydroquinones (H6, H7 and H12) showed the highest activity toward DPPH and exhibited better activity than TBHQ, a commercial antioxidant, possibly due to the formation of more stable phenoxyl radicals. On the contrary, synthesized benzoquinones had no activity. In Rotating Bomb Oxidation Test, three potent aforementioned compounds displayed antioxidant activity more than TBHQ observing from the longer period (IP value) for delaying autoxidation of base oils. The autoxidation inhibition of these compounds can occur in heterogeneous system and is not influenced by solubility confirmed by comparable IP values between H9 and its analogues bearing a lauryl group (L2).

title: Property Rights, Land Misallocation and Agricultural Efficiency in China

description: This paper examines the impact of a property rights reform in rural China that allowed farmers to lease out their land. We find the reform led to increases in land rental activity in rural households. Our results indicate that the formalization of leasing rights resulted in a redistribution of land toward more productive farmers. Consequently, output and aggregate productivity increased by 8 and 10%, respectively. We also find that the reform increased the responsiveness of land allocation across crops to changes in crop prices.
