title: Behavior of spirally prestressed concrete columns

description: Experimental work was performed to verify the initial idea of using a spiral post-tensioning system for creating an active confined pressure. Three spirally prestressed concrete cylinders were tested to study their strength and behavior under mid-span loading. Each specimen had four clockwise and four counterclockwise post-tensioning strands each making a complete revolution from one end of a specimen to the other. Results were compared to those of a nominally identical control specimen consisting of a similar concrete cylinder with the same number of longitudinally aligned post-tensioning strands. The specimens were designed to study the effect of: (1) the orientation of prestressing strands, and; (2) the percentage magnitude of applied strand prestressing force. A finite difference method was used for determining the capacity of specimens for setting up a test program. This method was simple and readily gave results based on approximating and simplifying assumptions. The finite element method which including a concrete plastic model, was performed to more closely study the behavior of spirally confined concrete. Using a system identification approach, a concrete model was calibrated by adjusting plastic parameters to correspond to known triaxial behavior. Subsequently the finite element model was compared to the test results to confirm that the concrete plastic model could be used for parametric studies. Finite element analysis was used to perform a parametric study for uniaxial compression tests. This parametric study focused on determining the uniaxial compressive model of concrete cylinders under spiral prestress confinement. A series of variables and parameters were set up to determine the relations of those parameters to the uniaxial compressive strength of concrete cylinders under spiral prestressed confinement.

title: Biodiesel from purified palm oil and palm fatty acid in supercritical methanol with sulfated zirconia catalyst

description: This study investigated transesterification and esterification of purified palm oil and palm fatty acids in supercritical methanol with SO[subscript 4][superscript 2-]/ZrO[subscript 2] catalyst. Firstly, the SO[subscript 4][superscript 2-]/ZrO[subscript 2] catalysts were synthesized at different conditions, characterized, and the results were compared with the commercial SO[subscript 4][superscript 2-]/ZrO[subscript 2] catalysts. Then, these catalysts were tested for the production of biodiesel by transesterification and esterification of purified palm oil and palm fatty acids. The most suitable catalyst was then selected for the study to determine the suitable operating conditions such as mass ratio of SO[subscript 4][superscript 2-]/ZrO[subscript 2] catalysts to reactants (0-1 wt%), reaction temperature (200-300 °C), reaction time (0-15 minutes), and molar ratio of methanol to reactatant, (6:1-42:1) for purified palm oil and (3:1-12:1) for palm fatty acid, on fatty acid methyl ester (FAMEs) yield. Then the effect of catalyst recycling on the FAMEs yield were determined and presented. In this work, the suitable preparation condition of SO[subscript 4][superscript 2-]/ZrO[subscript 2] catalyst was to immere 40 g of ZrO[subscript 2] in 18 ml of 0.1 mol/liter of H[subscript 2]SO[subscript 4] for 30 minutes at 70 °C, after which the catalysts were dried at 110 °C for 24 hours, and was calcined at 500 °C for 2 hours. The most suitable conditions for transesterification reaction of purified palm oil in supercritical methanol with SO[subscript 4][superscript 2-]/ZrO[subscript 2] catalyst were the molar ratio of methanol to reactants of 24:1 and the catalyst to reactants mass ratio of 0.5% at 250 °C, and the reaction was 10 min. For palm fatty acid, the ratio of methanol to reactants of 6:1, the catalyst to reactants mass ratio of 0.5% at 250 °C, and the reaction time of 1 min were the most optimal conditions. About 80% FAMEs yield was achieved for both purified palm oil and palm fatty acid. However, the limitation of SO[subscript 4][superscript 2-]/ZrO[subscript 2] catalyst was its rapid deactivation, which nevertheless could be solved by re-impregnation and re-calcinations.

title: Capacity analysis of MIMO rayleigh channel with spatial fading correlations and estimation errors

description: Multiple Input Multiple Output (MIMO) communications systems equipped with antennas array at both the transmitter and receiver ends are promising schemes to realize higher rate and/or reliable data transmitter and receiver ends are promising schemes to realize higher rate and/or reliable data transmission. In this thesis, capacity analysis of MIMO Rayleigh Channel with spatal correlation at the receiver of multipath is studied. In general, a model configuration of local scatterng around a mobile station in MIMO environment is carried out by simulaton to examine spatial correlation coefficients. Based on statistical properties of the eigenvalues of the eigenvalues of correlated complex random Wishart matrices, the exact closed-form expressions of distribution of the eigenvalues are investigated. Thaen, the eneral closed-form evaluation of integral form is proposed based on Meijer's G-function. The analytical results demonstrate that the ergodic capacties are improved by increasing the number of the antennas and signal-to-noise ratio (SNR's). Compared with independent identically distributed (iid) Rayleigh channel, the incremental improvement of correlated Rayleigh channel is reduced by spatial fading correlation. The analytical results validated by Monte-Carlo simulations that show a good agreement. In addition to the capacity analysis, the aspect of information theory of a practical MIMO transmission scheme is discussed, namely, spatial multiplexing MIMO system with zero forcing receiver which operating under realistic conditions such as spatially correlation, channel estimation errors, and delay feedback from the receiver to the transmitter. Results are presented for spatially correlated Rayleigh fading channels and estimation errors. It is demonstrated that the capacity of the system suffers degradation when the channel state information (CSI) is not perfect and in spatially correlated signals. A lower bound on mutual information is also derived for flat fading channel with the effective noise power matrix, which lead to simple study of insights.

title: Phorbol esters extraction from jatropha curcas residue kernel meals using surfactant solution

description: Phorbol esters (PEs) are toxic compounds found in the Jatropha curcas seeds. Due to their hydrophobic property, PEs still remain in Jatropha oil and residual meals after extraction process. This becomes a limitation for further applications of the oil and its meals. Even though the meals of Jatropha seed contains protein up to 40%, its toxicity restricts its application only for fertilizer production. To solve this problem, this work introduced a new technique to Pes removal in residual meals by using surfactant solutions. Nonionic surfactant and mixed surfactant solutions were investigated on PEs removal from residual meals obtained by various types of extraction methods. Determination of PEs were carried out by HPLC. The results show that the amount of PEs in the mechanical pressed meals was around 1.45 mg/g. The PEs removal efficiencies were 22.49%, 81.43%, 81.23%, 81.87% and 78.85% from water, single 40 mM Tween80, mixed 40 mM Tween80 with 5 mM AOT and 100 mM NaCl, single 40 mM Dehydol LS9, and mixed 40 mM Dehydol LS9 with 5 mM AOT and 100 mM NaCl, respectively. The optimal extraction time was 15 min. Re-extraction and increasing of liquid portion per solid portion was able to increase the removal efficiency of PEs. However, this technique only cannot remove PEs from the meals as low as those found in non-toxic variety. Nonetheless, this method can be considered as a promising technique for the PEs removal from the meal and hence, it can benefit the residue meal in term of value–addition for further application.

title: A comparative study of abortion issuen in Thailand and Vietnam

description: Abortion has so far remained one of the most hotly debated socio-cultural and health issues all over the world. The debate turns around the questions of whether or not abortion should be legal; who has the right to make the decision concerning abortion, the individual or the state; and under what circumstances it may be done. Obviously, each society with its own culture has different ways of coping with abortion issues. This research aims to explain the reasons for the differences in public policy towards the abortion laws between Thailand and Vietnam based on the similarities and differences in history, religion, culture and governance in the two countries, explore whether changing public attitudes and opinions in Thailand and Vietnam have had any impact on government policy, and put forward some suggestions for practical solutions to the abortion issues in both countries.

title: Oil extraction from jatropha seeds using mixed surfactants aqueous-based solution for elimination of phorbol esters in the oil

description: Due to the energy crisis and food demand, an exploration of non-edible oil bearing plants for biofuel and oleochemical production has been attended to protect the competition between food supply and biodiesel feedstock. The importance has been given on Jatropha curcas L. for fulfilling energy requirement. The innovation of Jatropha oil extraction using mixed surfactant aqueous-based solution could be the alternative extraction method for hexane extraction replacement because hexane is considered to be harmful to the environment and human health. However, the detoxification of phorbol esters in Jatropha oil, which considered to be the main toxic compound in term of tumor promoter and suspected to be carcinogen, is recommended prior to industrial utilization. The contamination of phorbol esters limit the application of methyl ester and glycerol from Jatropha-biodiesel production. Hence, this work proposed a new approach for Jatropha oil extraction using mixed surfactants aqueous-based solution. Theoretically, nonionic surfactant was selected to be mixed with extended anionic surfactant under the appropriate chemical proportion and physical conditions to obtain the highest oil yield. More importance, this method is expected to reduce phorbol esters in Jatropha oil. Experimental design includes the investigation of surfactant systems for the extraction, the optimum conditions, yield of oil extraction and the concentration of phorbol esters in the oil. The result shows that the optimal extraction system was 3% fatty alcohol C12-14 (2) ethoxylate nonionic surfactant, 0.02% Alfoterra 145-4PO and 0.6% sodium chloride which could yield the oil up to 73% for single extraction and could reach to 90% for double extraction. The appropriate extraction condition in this study were grain size 8-35 mesh, 1 min contact time with 130 rpm orbital shaking and 1 g of Jatropha kernel load per 10 mL of mixed surfactants aqueous-based solution or 1:10 solid to liquid ratio. Moreover, the phorbol esters concentration in the oil was reduced down to 1.84 mg/g which is significantly less than the oil obtained from hexane and compress extraction. Conclusively, this extraction method is considered to be clean technology concept and can be potentially useful for further development and application in the future.

title: Parkes observations for project P1016 semester 2019APRS_06

description: Understanding rotating radio transients (RRATs) has the potential to uproot our understanding of core-collapse supernovae and the overall evolution of neutron stars. Despite this, RRATs remain an enigma and has numerous potential and conflicting explanations in the literature. These observations will observe a sample of RRATs with the UWL receiver, in tandem with the Five-hundred-meter Aperture Spherical Telescope (FAST), in order to directly test many of the competing theories that exist around RRATs and answer the question of where they fit amongst the overall population of neutron stars.
