title: Production of methyl ester from palm stearin and fatty acid by two step method

description: To investigate the production of methyl ester by two step method. Palm stearin and fatty acids were used as raw materials and were mixed at a ratio of 10%, 15% and 25% of free fatty acids. The experiments were carried out in a batch reactor using sulfuric acid as a catalyst in the first step and potassium hydroxide in the second step. The experiments were conducted at the temperature of 60°C and at atmosphere’s pressure. Reaction time, methanol to oil ratio and amount of catalysts were varied in each experiment. The suitable conditions on acid esterification process were 300% mole of excess methanol from its stoichiometric ratio in the presence of 2% wt H2SO4 as a catalyst and at the reaction time of 70 minutes. High free fatty acids level was reduced to less than 2% in the first step. Acid catalyst can simultaneously catalyze both esterification of free fatty acids and transesterification of triglyceride. The suitable conditions on transesterification process were 100% mole of excess methanol from its stoichiometric ratio in the presence of 1% wt KOH as a catalyst in the second step. Final methyl ester was higher than 85% concentration within 60 minutes.

title: Primary response and saefty of 90yitrium ibritumomab tiuxetan followed by combined chemotherapy of cyclophosphamide, doxorubicin, vincristine, and prednisolone for diffuse large B-Cell lymphoma

description: To demonstrate the synergism between 90Yttrium ibritumomab tiuxetan (Y2B8) and commonly used antilymphoma drugs. The study was separated into 2 parts. First, to demonstrate the in vitro synergy in terms of direct cytotoxicity and antiproliferation to Ramos CD20-bearing lymphoma cells, 4-8 treatment arms due to drug order, different doses of 90Yttrium and 2 different incubation periods were designed. Synergy was justified by decreased IC50 and drug modification factors (DMF) greater than 1. Although 90Yttrium at 2 and 4 microCi/ml had no cytotoxic or antiproliferative effect, synergistic cytotoxicity was found when treated with doxorubicin (DMF 3.00-4.18), etoposide (DMF 1.96-2.36), and in 90Yttrium followed by fludarabine (DMF 2.99-3.52). Besides, combined 90Yttrium with cyclophosphamide, cytarabine (&lt; 0.2 micro g/ml), and vincristine provided 60-100% antiproliferative effect. Moderately high degree of synergy was found with 0.2-200 micro g/ml fludarabine assessed after 96 hours incubation period (DMF 91.24-91.69). In the second part exploring clinical response and safety of the regimen Y2B8 followed by CHOP (Y-CHOP) for diffuse large B-cell lymphoma, 10 patients (4 male, 6 female) were enrolled during April 2006-February 2007. The increased percentage of patients with complete response or unconfirmed complete response to 80% at 3 weeks after completion of CHOP indicated the development of good response along the program. However, 4 progressive/relapse cases were noticed at 3 months-visit. Factors related to progression were disease bulkiness and the presence of extranodal sites. Non-serious drop in neutrophil and platelet counts (nadir at 5.80 +-1.69 and 4.50 +- 0.71 weeks, respectively) were common adverse events due to Y2B8. Higher percentage of good response was demonstrated among patients with Bcl-2+ than those with Bcl-2-. As summary, the regimen Y-CHOP provided more benefit in treating diffuse large B-cell lymphoma. This is related to the in vitro synergism with these drugs. In-depth investigation of rapid relapse should be performed further.

title: Quantitative analysis of major isoflavonoids in the leaves of white kwao krua Pueraria mirifica

description: The RP-HPLC analysis of 5 major isoflavonoids including puerarin, diadzin, genistin, daidzein and genistein was applied to Pueraria mirifica leaves derived from 3 plant cultivars; PM-III, PM-IV and PM-V in every month from March, 2007 to August, 2007. The results indicated that there were only puerarin, daidzin and genistin, not daidzein and genistein present in P. mirifica leaves. The highest isoflavonoid contents during the 6 months were daidzin in PM-V (5,059.96+-365.61 mg/100g powder). The maximum amount of puerarin (468.19+-83.55 mg/100g powder) and genistin (3,062.35+-382.13 mg/100g powder) were found in PM-V, while the maximum daidzin amount was found in PM-V. The total isoflavonoid contents of PM cultivar in June 2007 were the highest (5,766.34+-411.27 mg/100g powder) and in April 2007 was the lowest (509.03+-45.06 mg/100g powder). The lowest puerarin (62.88+-15.02mg/100g powder) and daidzin (194.63+-18.32 mg/100g powder respectively) were found in PM-III where as the minimum genistin was found in PM-V (131.59+-18.22 mg/100g powder). The results demonstrated that the leaf isoflavonoid contents were under the influence of plant genetics and monthly climatic change. The highest total isoflavonoid amount in PM-V was found in June 2007 which was 11.33 times higher than the lowest amount of PM-III in April 2007. The isoflavonoid contents of PM cultivar in June 2007 were the highest which was 2.93 times higher than in April 2007. The study demonstrates the highly biotechnological potential of manufacturing puerarin, daidzin and genistin from the cultivated P. mirifica leaves.

title: Dataset: Parallel Implementations Assessment of a Spatial-Spectral Classifier for Hyperspectral Clinical Applications

description: Hyperspectral (HS) imaging presents itself as a non-contact, non-ionizing and non-invasive technique, proven to be suitable for medical diagnosis. However, the volume of information contained in these images makes difficult providing the surgeon with information about the boundaries in real-time. To that end, High-Performance-Computing (HPC) platforms become necessary. This paper presents a comparison between the performances provided by five different HPC platforms while processing a spatial-spectral approach to classify HS images, assessing their main benefits and drawbacks. To provide a complete study, two different medical applications, with two different requirements, have been analyzed. The first application consists of HS images taken from neurosurgical operations; the second one presents HS images taken from dermatological interventions. While the main constraint for neurosurgical applications is the processing time, in other environments, as the dermatological one, other requirements can be considered. In that sense, energy efficiency is becoming a major challenge, since this kind of applications are usually developed as hand-held devices, thus depending on the battery capacity. These requirements have been considered to choose the target platforms: on the one hand, three of the most powerful Graphic Processing Units (GPUs) available in the market; and, on the other hand, a low-power GPU and a manycore architecture, both specifically thought for being used in battery-dependent environments.

title: Expression and function of toll-like receptors on dendritic cells and other antigen presenting cells from non-human primates

description: Antigen presenting cells (APCs), especially dendritic cells (DCs), play a crucial role in immune responses against infections by sensing microbial invasion through toll-like receptors (TLRs). Thus, TLR ligands are attractive candidates for use in humans and animal models as vaccine adjuvants. So far, no studies have performed on TLR expression in non-human primates such as rhesus macaques. We therefore performed a comparative cross-species study on TLR expression patterns (TLR3, 4, 7, 8 and 9) of APCs in human, rhesus macaques and mice. We demonstrate that blood DC subsets of rhesus macaque expressed the same sets of TLRs as human DCs but substantially differed from mouse DC subsets. In macaque and human, myeloid DCs (MDCs) expressed TLR3, 4, 7 and 8 whereas plasmacytoid DCs (PDCs) expressed only TLR7 and 9, in contrast to mouse, both DC subsets expressed all TLRs (TLR3, 4, 7, 8 and 9). Additionally, TLR expression patterns in macaque monocyte-derived dendritic cells (mo-DCs) (i.e., TLR3, 4 and 8), monocytes (i.e., TLR4, 7, and 8) and B cells (i.e., TLR4, 7, 8, and 9) were also similar to their human counterparts. However, the responsiveness of macaque APCs to certain TLR ligands partially differed from those of human in terms of phenotype differentiation and cytokine production. Strikingly, in contrast to human mo-DCs, no IL-12p70 production was observed when macaque mo-DCs were stimulated with TLR ligands. Our results provide important information for a rational design of animal models in evaluating TLR ligands as adjuvant in vivo.

title: Vehicle routing system for daily meal delivery with motorcycles

description: This thesis reports the development of a vehicle routing system for a daily breakfast delivery business. The business plans to hire motorcycles for the delivery operation which operates between 5:00 am to 6:30 am. The cost payable to each motorcycle employed consists of a fixed weekly fee and a charge that varies with the distance it travels in its delivery route specified by the company. The vehicle routing system aims to minimize the fleet size and the total travelling distance, which determine the cost of the delivery, with constraints on limited capacity and travelling time frame of each vehicle. The development process includes selection of the appropriate solution approaches, problem modelling, developing a computer program to solve the problem, data preparation, developing an operation procedure, and testing the system. The developed system applied the Savings algorithm and the A* search algorithm. The program was modified from an existing vehicle routing program for truck routing. The modified program was tested with published instances of the problem to verify that the developed system is effective and gives routing with small fleet size and short total delivery distance. In testing with survey data of 78 potential customers in the area of Rama IX Road, the system specified the use of four motorcycles. Each delivered 16, 29, 22 and 24 units respectively which did not exceed its capacity of 40 units. Each motorcycle delivered the meals to the last customer in 44 minutes, 1 hour 19 minutes, 1 hour, and 56 minutes respectively which are within the specified time frame. The system was also used to experiment for the possibility to improve results. It was found that it is possible to reduce the fleet size from four to three vehicles by relaxing the time frame or reducing the time spent at each drop off point.

title: State policy on small and medium enterprises (SMEs) : a case study of morally sensitive enterprises of district 1 In Ho Chi Minh City

description: Thanks to the transformation to market economy and international integration of Vietnam, the role of private sector takes a vital part in the economy, in which SMEs take over 95% of the total number. However, despite their significant contribution, SMEs working in “sensitive” services still have faced many obstacles when obtaining the business registration certificate in Ho Chi Minh City. The purpose of the research is to study the factors influence issuance of business registration certificate for “sensitive” SMEs in the context of Vietnam’s transformation to market economy and WTO penetration. Findings from the study prove that issuance of business registration certificate for sensitive enterprise is complicated, non-transparent, and unreasonable. Especially, contrary to the hypothesis, the study finds various opposite viewpoints of officials due to their ideology. Based on the findings, it can be concluded that this policy failed due to some reasons: (i) bias of conservative officials against “sensitive” businesses; (ii) inadequate interpretation of the policy by street-level bureaucrats; (iii) poor knowledge of the public about regulations on the business registration; (iv) traditional prejudice of the public perception as well as mass media towards private sector. Overall, in the context of economic transition and global integration, two conflict principles market economy versus social morality also contribute to the policy failure. Last but not least, in order to close this research, the author recommended prospective researches researchers pay much more attention to actions and the role of street-level bureaucrats when studying policy implementation in Vietnam.

title: Unsupported transition metal sulfide catalysts for deep hydrodesulfurization of hydrocarbon fuels

description: The requirement of clean fuels has resulted in a continuing worldwide effort to dramatically reduce the sulfur levels. This is driving the need for more active hydrodesulfurization (HDS) catalysts. The purpose of this research is to study the potential of unsupported Mo based sulfide catalysts prepared from hydrothermal method. The unsupported catalysts exhibited the excellent activity for the simultaneous HDS of dibenzothiophene (DBT) and 4,6-dimethyldibenzothiophene (4,6-DMDBT). Activity and surface area of catalysts depend strongly upon the preparation temperature and pressure. Organic solvent added in catalyst preparation helps to improve the dispersion of the precursor molecules. The unpromoted and promoted (Co or Ni) Mo sulfide catalysts have different properties and activity. Addition of promoter decreased surface area and pore volume. TPR analysis suggested that promoter decrease metal sulfur bond strength. HRTEM and XRD results showed that the growth of catalyst particle was suppressed when promoter was added. The promoter increased HDS activity of MoS[subscript 2] and changed the contribution of the direct-desulfurization and of hydrogenation pathways. The main effect of the promoter was to increase the rate of C-S bond cleavage. The liquid-phase adsorption of DBT and 4,6-DMDBT was used to study the adsorption capacity and mechanism over the synthesized catalysts. The results showed that the promoters not only increase active site number, but also enhance activity of active sites of the Mo sulfide.

title: Politics and bureaucracy behind Thai government's issuance of compulsory licensing (CL)

description: To elaborate and identify the determining factors that led to the Thai government’s issuance of CL during the military-installed government of General Surayud Chulanont (October 2006 - January 2008). This research places an emphasis on two contexts: 1) national politics that provided political opportunities following the September 19, 2006 coup d’état; and 2) the Thai Ministry of Public Health (MoPH)’s bureaucracy and its key features. Research findings revealed that national politics was a determining factor. The conceptual framework of “Political Opportunity Structure (POS)” was applied to analyze the changed dimensions of the Thai state that provided incentives for MoPH bureaucrats to undertake collective action and to eventually bring about CL. It found that previous Thai governments and concerned authorities, particularly during the period of 1998-2006, had been submissive and could not withstand international pressure and trade sanctions. Thus the issues of access to medicines was not taken as a priority, and was even swept aside when the country was under increasing domination of neoliberal globalization and international trade interests. Research findings showed that the September 19 coup opened up political opportunities for the Thai government’s ability to issue CL. The political opportunities include the reconfiguration of national cleavage structure and institutional structure. Research findings showed that the MoPH’s bureaucracy was another determining factor. This research applied the framework of “Politico-Administrative Structure (PAS)” to characterize the relationship and bargaining among bureaucrats (political and civilian) as well as between bureaucrats and non-state actors (civil society and drug TNCs). It elaborated that cultural and structural/functional features of the MoPH’s bureaucracy were accountable. Cultural elements were manifested in two aspects: 1) the MoPH’s philosophy; and 2) institutional perceptions on the right to access to healthcare and medicines at both the national level and the level of the MoPH. Structural and functional dimensions also significantly contributed to the issuance of CL by transforming structural limitations into an active (functional) administrative policy. The success of CL issuance derived from four major implications: 1) decentralization and authority dispersion; 2) putting a panel under the direct supervision of the MoPH Minister; 3) not deferring the final decision to the cabinet; and 4) using the prevailing strategy of “highly coordinated” in dealing with health civil society. Lastly, this research built on preceding analysis and offered a reassessment of capacity, authority, and autonomy behind the Thai government’s issuance of CL. Among these three fundamental aspects, research findings proved that autonomy was a determining factor.

title: Flow contribution of multilayer oil system

description: To investigate the condition that kh rule can be applied for flow contribution of multilayer oil system. The controlling factor in case that flow contribution does not obey kh rule is investigated. The investigation used reservoir simulation generation the flow contribution on various cases. The systems for this study are two-layer system and three-layer system. The main system for study is two-layer system while three-layer system used to demonstrate or confirm conclusions for two-layer system to apply for more layer system. The controlling factors that are emphasized for this thesis are flow capacity (kh) and pore volume of layer Ah. In addition, the effect of fluid properties is investigated. From the study flow contributions are controlled by kh rule pore volume of layer Ah rule and not controlled by individual parameters in these groups. Flow contribution obeys kh rule when the flow from the system is at fully flow capacity (kh) and only at starting period of production time. Flow contribution obeys pore volume when the flow from the system is lower than flow capacity and is affected by pore volume due to oil expansion. There are other controlling factors affecting flow contribution, i.e. presence of free gas, pressure depletion, and expandable fluid. Most controlling factors affecting flow contribution are related to energy in the reservoir except kh. There exists effect of fluid properties to flow contribution in the system, but flow contribution is still under influence of flow capacity and pore volume.

title: Correlation between heat flux, moisture and wind pattern over the Indian Ocean and Southwest monsoon intensity in Thailand by using MM 5 numerical model

description: The NCAR’s Mesoscale Model MM5 was used to compute the heat flux, moisture and wind pattern over the Indian Ocean from Latitude 30 degree S to 300 degree N and longitude 40 degree E to 120 degree E for 5 years. The data are used only during the southwest monsoon season from May to October in 1996 to 2000, which covered El Nino year (1997) and La Nina year (1998). The correlation of these parameters was relatively high with R [superscript 2] = 0.723 in normal year to the rainfall pattern at the 13 synoptic weather stations in Thailand. In normal year, when the heat flux over the southeast Indian Ocean near the west coast of Australia was increased and persist for approximately 5 days before the average onset date of wet monsoon season (on 15 May) for 11 days, this caused the onset of southwest monsoon at 9 stations in Thailand to start around the average of the southwest monsoon date In El Nino year, the onset of southwest monsoon at most stations was delayed than the average date for 50 days with lesser intensity than normal year. In La Nina year, the onset of the southwest monsoon at most stations were sooner than the averages date for 5 days with stronger intensity than normal. The result of this study will be used by Thai Meteorological Department to predict the onset of southwest monsoon for agricultural activities more accurately than the present method.

title: Cost analysis of medical specialty training programme in Sri Lanka

description: To analyze the programme cost of the postgraduate medical specialty training in Sri Lanka. Total programme cost and the Programme cost for Medical Microbiology training (as an example of postgraduate training) were analyzed. The data for the analysis were collected from the information available at the Postgraduate Institute of Medicine (PGIM). Some of the data were available from the reports published by the PGIM, while others were collected through interviews with responsible officers. The cost of medical specialty training involves 6 years curriculum that is necessary to become a specialist in the field of Medical Microbiology. The units of Postgraduate Institute of Medicine (PGIM) divided into 28 cost centres and categorized as administration, education and education supporting units. The data collection forms were used as tools to collect the data in 2007. The information was compiled as labour cost, material cost and capital cost. Direct allocation method was applied to allocate all costs in each cost centre with using the allocation criteria.Total cost of Postgraduate Institute of Medicine is SLR 53,873,222.57 for the year 2007. The total programme cost comprises of SLR 30,338,036.04 as labour cost and SLR 18,071,521.57 and SLR 5,453,653.90 as material cost and capital cost respectively. The programme cost for the Medical Microbiology training was SLR 5,436,914.90, consisted three stages in the field of Medical Microbiology. The cost for the Diploma in Medical Microbiology was SLR 472,870.00. In second stage of MD in Microbiology, cost was SLR 445,337.00. Cost for the Board Certification as a Specialist in Microbiology was SLR 2,791,750.00, this mainly involves overseas training component of the postgraduate programme. The study found that the largest potion (more than 50%) was utilized for the overseas training when compared with other stages in the training programme. This should be an area for further policy development to be strongly be considered by the management of the PGIM, as well as by the Ministry of Healthcare & Nutrition. Cost of the overseas training of the postgraduate training may be reduced by many means and this has to be carefully considered not to compromise the quality of training. Lose of overseas trained medical postgraduates due to non-returning candidates is another important factor that need to be seriously considered by the PGIM and Ministry of Healthcare & Nutrition.
