title: DNA fingerprints, chromatographic patterns and bioactivities of “Rang Chuet”

description: Thunbergia laurifolia Lindl., a member of the Acanthaceae family, is commonly known in Thai as “Rang Chuet”. The “Rang Chuet” herbal drugs have been widely used in Thai traditional medicine for the treatment of poisoning caused by toxic substances such as insecticides, ethyl alcohol, and metals. However, the confusion of the herbal drugs has arisen from the homonymity and close appearances of materials with different botanical origins. T. laurifolia, the most known species, has been substituted with other plant materials including Curcuma sp., Rinorea sp., and Crotalaria spectabilis. Therefore, authentication of specific “Rang Chuet” herbal drugs is necessary to ensure the authenticity and efficacy. TLC chemical characterization combined with molecular techniques including RAPD and PCR-RFLP offers highly reliable identification procedures. T. laurifolia was successfully differentiated from its related species based on the characteristic flavonoids and phenolic compounds. Variation sites in the matK gene of the species can be recognized by the restriction enzymes, DdeI and HaeIII. Two other species of herbaceous Thunbergia, T. grandiflora and T. erecta, were also included in the RAPD analysis. Out of 80 screened RAPD primers, nine primers gave clear and reproducible patterns with a total 70 polymorphic bands. Additionally, an HPLC system was developed for the determination of rosmarinic acid, a potent antioxidant, which represents a suitable biochemical marker for T. laurifolia. The established method has potential application at the commercial level for assessing the quality of T. laurifolia. Since “Rang Chuet” herbal drugs from different plant origins differ in their antioxidant activities, the use of “Rang Chuet” herbs should be done with care.

title: Coupled CO₂ sequestration and enhanced condensate recovery in gas condensate reservoir using experimental design and response surface methodology

description: Valuable condensate in gas condensate reservoirs which will drop out and is left in the reservoir at reservoir pressure lower than dew point pressure can be recovered via CO2 injection by the mechanism of condensate re-vaporization as a result of pressurization. At the same time, part of the injected CO₂ can be sequestered in the reservoir, allowing the methodology to be attractive.The objective of this study is to investigate the application of CO₂ sequestration and enhanced condensate recovery in gas condensate reservoir for different flood design parameters and strategies using compositional reservoir simulation model. It is to better quantify the potential of reservoir condition over a wide variety of parameters and strategies with the need to find optimum operational strategies with the aid of Experimental Design and Response Surface Methodology. The parameters and strategies studied include permeability, injection scheme (water alternating gas vs. continuous CO₂ injection), injection and production well type (vertical vs. horizontal), vertical to horizontal permeability ratio, injection rate, well spacing, and injection time. The amount of CO₂ stored and condensate recovery factor are considered as two responses.The results show that 1000-md permeability gas condensate reservoir with high kv/kh has potential to implement. Optimum strategies are provided by Experimental Design with less time and cost compared to full runs of simulation.

title: Analysis of fractures in 3D linear piezoelectric media

description: This paper presents a numerical technique called a weakly singular, symmetric Galerkin boundary element method (SGBEM) that can be used to analyze cracks in three-dimensional, generally anisotropic, linear piezoelectric infinite and finite media under various types of electrical boundary conditions including impermeable, permeable, semi-permeable and Landis-type conditions. One of advantage features of the present technique is that the governing equations are in symmetric forms, which are obtained by using two sets of boundary integral equations: the first one is the integral equation for the generalized displacement (i.e. displacement and electric potential) and the other one is the integral equation for the generalized traction (i.e. traction and surface electric charge). Since such pair of integral equations contain only weakly singular kernels of O(1/r), the standard ℃-interpolation functions can be employed to approximate the solutions by using the Galerkin scheme. Another positive feature is the use of special crack tip elements along the local region of the crack front to accurately model the near tip field.As a result, the stress and electric intensity factors can therefore be obtained accurately by using relatively coarse meshes. The weakly singular SGBEM is validated through various numerical experiments for both infinite and finite boundary value problems under several types of electrical boundary conditions. It was found that obtained results for a penny-shaped crack are in excellent agreement with the exact solutions. Subsequently, more complex problems are treated to demonstrate the versatility of the current technique to model cracks and bodies of various geometries under various loading conditions. Finally, the influence of electrical boundary conditions on the stress intensity factors and the electric intensity factor for piezoelectric infinite and finite media is thoroughly investigated.

title: Effect of water and formation compressibility and water vapor on original gas in place estimation using material balance calculation

description: In gas field development, one of the most important decision factors is reserve estimation. Inaccurate reserve estimation can lead to incorrect economic decision and production plan. The main reasons that may lead to an error in such estimation are water and formation expansion and water vaporization. Exclusion of such factors can result in error of original gas in place when using material balance equation. The objective of this thesis is to study the effect of water and formation expansion and water vapor in OGIP estimation in dry gas reservoirs having different reservoir conditions. This study also investigates how the length of data affects the estimation.The study consists of two parts: (1) estimation of OGIP for reservoirs with significant water and rock compressibility, the conventional, Ramagost and modified Ramagost methods are used to determine OGIP and (2) estimation of OGIP for reservoirs with significant rock compressibility and water vapor, the conventional, Humphreys and modified Humphreys methods are used to compute OGIP. In the first part, it was found that modified Ramagost method provides the most accurate OGIP estimates when a lot of production data are available and the Ramagost method provides the best results when limited production data are available. Furthermore, the error rises when the initial pressure is higher. In the second part, modified Humphreys method provides the most accurate OGIP estimates when a lot of data are available and the Humphreys method provides the best results when limited production data are available. Similar to the first part of study, higher initial pressure results in higher error of OGIP estimate. The increase in water vapor content does not change the magnitude of the error for reservoirs with low initial pressures but increases the error for reservoirs with high pressure.

title: Analysis and optimization of biodiesel production from Jatropha oil using reactive distillation

description: Biodiesel is considered a potential substitute of fossil fuel as it is clean and renewable. Edible oils such as palm oil and soybean oil are commonly used as feedstock in biodiesel production; however, using these feedstock cause shortage of vegetable oils for human consumption. This study was concentrated on the development of a biodiesel production process from Jatropha oil, a non-edible vegetable oil. As Jatropha oil always contains about 14% of free fatty acid, the biodiesel production process considered consists of a hydrolysis section where triglyceride is converted to fatty acid and an esterification section where fatty acid reacts with methanol in the presence of acid catalyst to produce methyl ester (biodiesel). The utilization of a reactive distillation was proposed to improve the performance of the esterification process. Simulations of the biodiesel production process using a process flowsheet simulator were carried out to identify important operating parameters. The response surface methodology (RSM) based on a central composite design (CCD) was used to determine optimal operating conditions for biodiesel production. The conditions to get optimal response with 99.9% were found to be 126.4 kmol/h of bottom rate, 0.4 for reflux ratio, 160ºC for oleic acid feed temperature, methanol feed stage = 12 and oleic acid feed stage = 3. In order to minimize energy consumption, the pre-heated and methanol recovery of a reactive distillation process is considered.

The chemical structures of all isolated compounds were characterized according to physical means of spectral analysis as well as comparison with the previous literature data. All of the isolated compounds (1.1-1.14) were evaluated for their cytotoxicity on KB and HeLa cells. Compounds 1.2 and 1.7 exhibited moderate cytotoxicity against both KB and HeLa cells, with IC₅₀ values of 10.0, 5.5 µg/mL and 9.5, 13.0 µg/mL, respectively, while compound 1.4 showed only moderate cytotoxic against on HeLa cells (IC₅₀ = 10.0 µg/mL). The phytochemical investigation of the CH₂Cl₂ and MeOH crude extracts from the roots of A.acidum Retz. afforded a new natural (synthetically known) compound, corylifolin (2.2), togather with sixteen compounds including antidesmol (2.1), mellein (2.3), a mixture of β–stitosterol (2.4) and stigmasterol (2.5), 5-cholesten-3β-ol (2.6) and 4-cholesten-3-one (2.7), 3-(1,1-dimethylallyl)-scopoletin (2.8), 5,7-dihydroxy-2-eicosyl-chromone (2.9), 2,5-dimethoxy-1,4-bezoquinone (2.10), barbatumol A (2.11), N-trans-feruloyltyramine (2.12), syringic aldehyde (2.13), p-hydroxybenzoic acid (2.14), taxifolin (2.15), (+)-catechin (2.16) and (-)-gallocatechin (2.17). Compounds 2.9 and 2.10 showed only good cytotoxicity against on HeLa cells (with IC₅₀ values of 3.9 and 1.6 µg/mL) and compounds 2.12, 2.14 and 2.17 showed only moderate cytotoxicity against on HeLa cells (with IC₅₀ values of 12.3, 10.8 and 14.9 µg/mL), while compounds 2.10 and 2.12 showed only moderate cytotoxicity against on KB cells (with IC₅₀ values of 4.9 and 7.8 µg/mL). The investigation and evaluation for the AChE and BuChE inhibitory activity using Ellman colorimetric method indicated that compounds 2.2, 2.3 and 2.12 showed low inhibitory activity toward only BuChE with percentage inhibitory activity values of 47.78, 40.29 and 43.62, respectively.
