title: Prospectivity analysis using a mineral systems approach - Capricorn case study project (RP04-063-M436)

description: Opening up greenfields regions for minerals exploration programs is best facilitated through the understanding of regional minerals prospectivity. The Capricorn Orogen is a greenfields region, in which a multicommodity mineral systems analysis has been completed forming the basis of prospectivity analyses and mapping data included in this collection. Known mineral occurrences or deposits in the region formed from between the Paleoproterozoic and Neoproterozoic. Mineralisation can in related to basin development and orogenesis in the region, related to periods of supercontinent assembly and breakup that were manifested in the region through the contractional 2005 – 1950 Ma Glenburgh, 1830 –1780 Ma Capricorn, and c. 900 Ma Edmundian orogenies. These periods were preceded, and interspersed with periods of extension that may have included the 1680–1620 Mangaroon Orogeny, and led to the development of volcanosedimentary and sedimentary basins throughout the region. Prospectivity models were generated for several commodity groups of various ages and ore genesis mechanisms within the region that include combinations of Ni, Cu, PGEs, V, Ti, Au, Pb, Zn, channel Fe and U. The work has found a link between key mineral systems and a spatial relationship between disparate styles of mineral deposits in the region. Crustal-scale tectonic architecture was analysed by allying a 2D map view geological-geophysical interpretation with 2.5D magnetic and gravity joint inversions of selected profiles, a 3D Moho gravity inversion (MoGGIE), and inferences derived from 2D and 3D magnetotellurics and 2D reflection seismic and 3D passive seismic experiment conducted in the region. This work clearly illustrates different ‘zones’ of the Capricorn Orogen are prospective for diverse commodity groups due to the tectonic environment in which they developed through time. Major crustal-scale faults or shear zones that intrinsically control the location of known ore deposits in the area, are implied to be sites of fluid migration and proximal to sites of ore deposition. Of these, some are considered to be Archean in their origin, whereas others are thought to have developed during the early Paleoproterozoic and been re-activated through time, influence the formation of basins over them and perhaps the formation of ore deposits.

title: Preparation of spray-dried powders of lysozyme for pulmonary delivery using liposomes as a carrier

description: The purpose of this study was to develop and optimize the spray drying process for preparing spray-dried lysozyme-loaded liposomal powders with adequate properties for possible application in pulmonary delivery. Extruded liposomes were prepared from hydrogenated soybean phosphatidylcholine (HPC) with and without cholesterol (Chol). The extruded liposomes was then mixed with mannitol and lysozyme solutions and spray-dried into liposomal powders. The effects of HPC/mannitol ratio, presence of glycine as anti-adherent and HPC/Chol ratio on the properties of the spray-dried powders and the reconstituted liposomes were investigated. The spray-dried powders produced were characterized with respect to morphology, thermal property and crystallinity using scanning electron microscopy, differential scanning calorimetry and X-ray diffraction, respectively. Physicochemical properties of reconstituted liposomes, including encapsulation efficiency and size distribution, were evaluated after the powders were re-hydrated at physiologically relevant conditions. The most feasible formulation was further used for process optimization. The effects of spray drying process factors (inlet temperature, feed rate and total solid content) on the properties (yield, moisture content, particle size and entrapment efficiency) of the powders were investigated using the factorial design followed by the central composite design. The results indicated that the spray drying process was feasible in producing lysozyme-loaded liposomal powders. The process had no destructive effect on the stability of the major structural phospholipid. Degree of particle aggregation was strongly dependent on the composition of the powder. Though glycine could improve the yield in the collector of spray dryer, high amounts of glycine resulted in fusion of particles that prevented liposome formation upon reconstitution. At the lipid to mannitol ratio of 1:1, an increase in Chol resulted in a reduction of the size of the reconstituted liposomes. Entrapment of lysozyme in liposomes, on the other hand, increased with Chol content. After reconstitution with Hepes Buffered Saline, pH 7.4 at 37 ºC, the powders spontaneously formed liposomes. Lysozyme was efficiently entrapped into the reconstituted liposomes. Biological activity of lysozyme was not affected by the spray drying process. However, some structural changes were evident. From the optimization study, the results indicated that the spray drying factors had a significant influence on the yield, the particle size and the entrapment efficiency of the powders. The optimum condition selected gave the liposomal powders with process yield of 60.46 %, mass median diameter of 6.00 m and entrapment efficiency of 13.83 g LSZ/mg lipid.

title: Prepration of modified clay from Koh Kred and bentonite by pillaring for adsorption of benzene, toluene and xylene

description: The modification of Koh Kred’s clay and bentonite to develop new adsorbent for volatile organic compounds removal particularly for benzene, toluene, and xylene by cation exchange properties of clay or bentonite was investigated. Both clays were pillared with tetraethyl ammonium chloride, TEA, equivalent to 0.75, 1.00, 1.25, 1.50, 1.75, and 2.00 times of clay CEC so that the pillared clay became more organophillic. The results showed that more surface area could not be enhanced for Koh Kred’s clay by pillaring technique, whereas this could be possible for bentonite. After pillaring, bentonite’s Langmuir surface and micropore areas increased 26.27% or 145.1181 m2/g and 70.17% or 40.7804 m2/g, respectively. Considering adsorption capacity of benzene, toluene and xylene, PILB 32 was practically 1/7 times lower than activated carbon. But for surface area and yield reduction rate after regenerations, PILB 32 was found to be superior to activated carbon. Accordingly, due to specific structural characteristics of high thermal resistance at 800 OC. PILB 32 can be applied for some toxic substances which need to be treated under high temperature. Surface area and yield retaining properties exhibited that PILB 32 can help preserve resources and also reduce energy consumption.

title: Process development of ready-to-eat custard cream filled chinese steamed bun

description: Chinese steamed bun is a popular food in Asia. Its storage life is short as it is a high moisture food (HMF). Freezing is a good preservation method, however energy consumption is high. The objective of this study was to develop ready-to-eat custard cream filled Chinese steamed bun (CCSB) with shelf-life of at least 10 days by using hurdle technology. The hurdle parameters used were aw, pH, and modified atmosphere packaging (MAP). The effects of adding glycerol and fructose in custard cream filling and glycerol and lactic acid in Chinese steamed bun were studied by 3x3 factorial design experiment and response surface methodology using preference test on sweetness, texture, and overall acceptance (OAA) for the custard cream and appearance, flavour, texture, and OAA for Chinese steamed bun. It was found that optimum condition for custard cream filling was the addition of 6% glycerol and fructose each, which could reduce aw to 0.915 and the best condition for Chinese steamed bun was the addition of 2.5% glycerol and 0.25% lactic acid, which could reduce aw and pH to 0.912 and 5.78, respectively. From shelf-life study of Chinese steamed bun, the aerobic plate count (AC), aw, and pH of control and hurdle treated products (HP) at different levels of calcium propionate (CaP), packed in PVDC pouch and stored at 302OC, were investigated every 2 days. The results showed that HP without CaP can be stored for at least 16 days similar to HP with CaP and aw increased slightly while pH did not change. From textural measurement by texturometer and sensory evaluation (OAA) of HP without CaP compared with control sample, it was found that shelf-life of this product can be extended to 8 days without the detection of difference by panelists. The shelf-life study of hurdle treated CCSB by MAP using oxygen absorber (OA) showed that CCSB with OA can be stored for 10 days while CCSB without OA can be stored only for 4 days based on microbiological test. However, from textural measurement and predicted OAA score the shelf-life of CCSB with OA was 8 days.

title: Production of pure Ethanol from azeotropic solution by pressure swing adsorption

description: Pressure swing adsorption (PSA) is attractive for final separation in the process of water removal especially for fuel ethanol production. Despite many researches on simulation and experimental works on adsorption of water on 3A zeolite in a fixed bed, none have studied a process with the actual PSA system. The purpose of this research was to study the PSA process with two adsorbers and effects of several parameters. The research also included analysis of kinetic and thermodynamic data of ethanol-water adsorption on commercial 3A zeolites in a single fixed bed. Two-level factorial design experiment was used in this research work to preliminary screen the influence and interaction among each factor. Effects of important parameters such as initial temperature, feed concentration and feed rate were investigated. It was proven that Langmuir isotherm could best predict the experimental results with the corresponding equation of q = (8.18C)/ (1+42.83C). In the PSA pilot test, the principal factors, which had effects on the performance, were feed rate, feed concentration, adsorption pressure and the cycle time. Prediction of the process efficiency in terms of ethanol recovery and enrichment was proposed in the form of regression models. The results of the study in a fixed bed adsorber could help designing a pilot scale PSA unit. The experiments proved to be successful in terms of continuously producing high concentration ethanol with high percentage of ethanol recovery. With further simulation works the process could be scaled up for an industrial use.

title: Proteomics of manila tamarind seeds Pithecellobium dulce

description: Pithecellobium dulce Benth. belongs to the Leguminosae family, which contains important components of human diets owing to their high protein content. The present study aimed to identify seed proteins from Pithecellobium dulce using a proteome approach by two-dimensional gel electrophoresis (2-DE) and tandem mass spectrometry. The 2-DE protein map revealed a total of 317 distinct protein spots, including a cluster proteins located in the acidic region with molecular masses of 55–97 kDa. Ninety-six of the most abundant protein spots were analysed using nano liquid chromatography/tandem mass spectrometry (nano-LC/MS/MS), from which 27 proteins and further four proteins from the highly abundant protein cluster were successfully identified through the query of acquired tandem mass spectral data used in Mascot and MS-driven BLAST homology searches, respectively. Moreover, the biological activity of Pithecellobium dulce seed proteins was identified in this research. An antifungal activity protein toward Macrophomina phaseolina with a molecular mass of 14.4 kDa was purified using a procedure that involved Tris buffer extraction, ammonium sulfate precipitation, anion exchange chromatography, and gel filtration chromatography. The result acquired from tandem mass spectrometry with Mascot database searching shows that this protein has partial amino acid sequences similar to chicken egg white lysozyme.

title: Quality variation management for drying process in Thai agro-industry

description: Drying process is a very important process for Thai agro-industry. It is used to preserve agricultural products in order to prolong their shelf lives by reducing their moisture content to the quality target. However, a major problem related to the quality of the dried product is still found. The dried product cannot be reduced the moisture content to its target. Therefore, this aim of this dissertation is to manage the quality variation for drying process in Thai agro-industry. This dissertation is conducted with four types of the dried product as paddy rice, cassava chip, tobacco, and longan. All of them are important commercial product for Thailand. This dissertation begins with finding the drying time for each drying phase. After that, fuzzy c-means clustering is selected to organize the raw materials into the same clusters. It can help to reduce the dried product quality variation from the variety of the raw material. As a result, three clusters as low, medium, and high moisture content are the optimal number of clustering. After clustering, the raw materials are transferred to the drying process which can be divided into three phases as heating, drying with a constant drying rate, and drying with falling rate phases. The optimal drying temperature level and the mathematical model representing the behavior of the moisture content during the drying period are obtained. Moreover, adjustment drying temperature period is added and proposed by this dissertation to minimize the dried product quality variation.

title: Redox-linked structural changes in cytochrome C probed by stationary and time-resolved surface enhanced infrared absorption spectroscopy

description: The application of surface enhanced infrared absorption (SEIRA) spectro-electrochemistry for studying an immobilized protein yields advantages with respect to its surface sensitivity and probing the whole protein backbone. For an electrostatic immobilization, cytochrome c (Cyt-c) was adsorbed on a Au electrode via a binding to self-assembled monolayers (SAMs) of variable-length ω-carboxyl alkanethiols. In this work, stationary SEIRA measurements were performed to elucidate the structural changes of the SAMs, the redox-linked structural and orientational changes of the immobilized Cyt-c, and to study the non-native B2 state of Cyt-c. For the first time, the application of time-resolved SEIRA spectroscopy was reported to probe the protein dynamics coupled with the redox processes of Cyt-c. Potential dependent spectral changes of the SAMs revealed only reversible variations within the potential range of interest (-0.1 to +0.2 V), which do not interfere with the investigation of Cyt-c bound to these SAMs. However, depending on the SAM-lengths, irreversible spectral changes could be found also at certain potentials outside the mentioned range. The -turn III (1673 cm-1) and -turn II/ -helix (1660 cm-1) segments of ferric Cyt-c revealed orientational changes with respect to the surface under the influence of the electric field strengths, which were found to be correlated with the conformational transition from the native B1 to the non-native B2 state. The potential dependent spectra of the B2 conformation obviously differ from that of the B1 state. It reveals broad complex bands caused by an alteration of the tertiary structure and an arrangement of the hydrogen-bonding interaction involving the movement of peptide backbone of -turn II/ -helix (ca. 1659 cm-1) and unordered (ca. 1645 cm-1) structures for the formation of non-native B2 conformation. The redox potentials of the B1 state determined by stationary SEIRA spectroscopy and cyclic voltammetry (CV) are not significantly different from that in solution. CV measurements demonstrate a reversible electron transfer (ET) process and a non-exponential distance-dependence of the ET rate. On the basis of characteristic of redox state sensitive amide I bands, the protein structural changes triggered by the ET are monitored by rapid scan and step scan SEIRA spectroscopy in combination with the potential jump technique. Whereas the temporal evolution of the conjugate bands at 1693 and 1673 cm-1 displays the same rate constants as ET rate, the time-dependent changes of the 1660-cm-1 band are slower by about a factor of 2. The study demonstrates that time-resolved SEIRA spectroscopy provides additional information about the dynamics and mechanism of interfacial processes of redox proteins, thereby complementing the results obtained from other surface-sensitive techniques.

title: Freedom of information law in ASEAN : a lesson from Thailand to Indonesia

description: The objective of this thesis is to study the 12 years experiences of using the Freedom of Information Act in Thailand in order that Indonesia can use it as fundamental information before the same act will be effective in 2010. The method of this research involves review of the secondary sources from primarily books, related publications, online documents, as well as in-depth interview with informed respondents. The research finds that in Thailand the idea of using Freedom of Information Act was initiated by the government but the enforcement of the law lacks promoting and educating the public to make successful use of this law. The study finds that the law has its positive aspect, in that it empowers the public and serves as a tool for journalists as well as members of the public to inspect the government functions. However; the long-embedded culture of secrecy and periodic political interferences are found to be a major impediment to a successful enforcement of the law. Meanwhile, unlike Thailand, Indonesia has launched their version of a freedom of information law primarily through the initiative of civil society organizations. A comparison of the two information laws finds differences in detail like types of unrevealed documents, time of processing a complaint, appeal procedures and penalty. The most significant distinction is Information Commission of Indonesia is an independent agency while the Official Information of Thailand is under the government. Factors presented in this thesis could be useful for both Thailand and Indonesia to correct, improve and apply their laws to suit the circumstances.

title: Role of humic substances on degradation of aromatic compounds by oxidoreductive enzymes

description: To improve the efficiency of bioremediation strategies, we must understand the effects of humic substances (HS) on pollutant biodegradation. The possible roles of humic acid (HA) and fulvic acid (FA) are that they: 1) can deactivate enzyme responsible for biodegradation, 2) can act as competitive enzymatic substrates or 3) are enzymatically inert but sequester the pollutant substrate and protect it from enzymatic degradation. In part 1 experiment, degradation of pentachlorophenol (PCP) by purified laccase isolated from Trametes versicolor in combination with one of these HS, Aldrich humic acid (AHA), Leonardite humic acid (LHA), Suwannee River fulvic acid (SRFA), and Waskish peat fulvic acid (WFA) at 28°C and pH 5.0 was studied. In part 2, degradation of phenanthrene by crude fungal ligninolytic enzymes from Agrocybe sp. CU 43 in addition of HS and dissolved organic matter (DOM) from rice paddy field soil were used to test those three hypotheses. Both experiments showed that HS and DOM exhibited inhibitory effects for enzymatic degradation of the pollutants. The enzymatic degradation rate of the pollutants was slower with the increase concentration of HS and DOM. However, HS and DOM could not deactivate enzymes. HS and DOM showed the capabilities to associate with PCP and phenanthrene, protecting the pollutants from enzymatic degradation; consequently the pollutants’ bioavailability was decreased. The inhibitory effect of HS and DOM by competitive or linear mixed types for the pollutant degradation suggest that HS and DOM could, moreover, be substrates for the enzymes. Lower degradation rate constants (ḱ) were found in HS with higher inhibitor binding constants (Ki) and binding constant (Kdom). Terrestrial HA which occupied higher % aromaticity and molecular weight exhibited stronger Ki and Kdom than aquatic FA. This is the first time to clarify the mechanisms by which HS and DOM alter enzymatic degradation rate of the model pollutants. We proposed the model of which once aromatic pollutants enter the environment containing HS and DOM, they could firstly be sorbed to HS and DOM, decreasing biodegradation rate. Then, unbound pollutants would be degraded by enzyme, while HS and DOM could act as substrates for enzymes. Amount and nature of HS and DOM could be important factors in the sorption phenomena and inhibitory effect. Higher aromaticity and molecular weight HS showed the higher propensity in sorption and stronger inhibitor, providing longer time for bioremediation.
