title: Loss mechanism of multi-flavor compounds in microencapsulation process by spray drying

description: Some Thai herbals are volatile and chemically unstable in the presence of air, light, moisture and high temperature. To limit flavor degradation or loss during processing and storage, it is useful to encapsulate volatile compounds prior to its use in foods or beverages. In this research, flavor was encapsulated with carrier solution such as gum arabic or modified starch and transformed to solid by spray drying process. Bergamot oil was used as multi-flavor model. The main compositions of bergamot oil were d-limonene, linalool and linalyl acetate. The purpose of this research is to understand the loss mechanism of multi-flavor compound during microencapsulation process by spray drying. The loss of multi-flavor and single flavor were affected by many factors such as ratio of flavor to solid, emulsion droplet size, powder size, flavor properties, spray drying condition and diffusion coefficient of flavor. The results demonstrated that multi-flavor gave higher retention than single flavor because of the interaction between each flavors. The transformation of sensitive flavors was occurred during the spray drying process. The volatile release of spray dried powder depended on the solubility of flavor, powder size, temperature storage and RH. This implied that flavor release was governed by the interaction of flavor and matrices.

title: Hydrothermal treatment of water hyacinth leaves for glucose production

description: Water hyacinth available excessively in various water resources can affect ecological system, leading to many public problems. Especially, excessive of water hyacinth bundles could block the floodway leading to the historical flooding of Thailand in 2011. Water hyacinth is a typical lignocellulosic material which is recognized as a potential source of renewable energy. In this present study, hydrothermal treatment on water hyacinth (Eichhornia crassipes) was performed in a temperature range of 160 to 220 ℃ to examine an optimal yield of glucose. After treatment, the product was further hydrolyzed by cellulase. The effect of CH₃COOH as an organic catalyst on liquid composition was experimentally investigated. The liquid fraction was characterized by high performance liquid chromatography (HPLC) using refractive index detector (RID) to analyze the amount of glucose. The solid fraction was also analyzed by United States Department of Agriculture’s method (USDA’s method) to determine the amount of cellulose, hemicellulose, and lignin. The results showed that with the absence of CH₃COOH at 220 ℃, a glucose yield of 26.7% was obtained. Meanwhile, the highest glucose yield of 85.5 % was achieved under the condition of 200℃ with 0.75wt% CH₃COOH and 10wt% water hyacinth intake. A pseudo-first-order kinetic model with regard to cellulose content was developed to explain the conversion mechanism of cellulose to glucose in the hydrothermal treatment process. Based on the estimated rate constants results, this study was in a good agreement with other pervious investigation.

title: Removal of tar from biomass gasification process by steam reforming over nickel catalysts

description: Tar is a major problem in a biomass gasification process, causing blocking, fouling, corrosion, erosion and abrasion of process equipments. Tar steam reforming is a very attractive technique for tar removal. It converts high molecular weight hydrocarbons of tar into smaller gas products including H₂, CH₄, CO and CO₂. Preliminary research focuses on simulation of tar steam reforming. It was assumed to be at thermodynamic equilibrium and the calculations were performed using Aspen plus. The simulation results help understand the effect of operating condition and identify suitable operating conditions (reaction temperature, S/C ratio) for the experimental tar steam reforming. Representative tar consisted of toluene, naphthalene, phenol and pyrene whose compositions varied with temperatures of biomass gasification (700-900℃). The experimental study of the tar steam reforming reaction were carried out at different temperatures (450-650 ๐C), S/C ratios (1-5), type of supports (Al₂O₃, CaO, MgO) and %metal loading of a nickel catalyst. The experimental results follow the trends observed from the simulations that the reaction at high temperature and S/C ratio produce more hydrogen content. 20%Ni/Al₂O₃ was reported as a suitable catalyst which offered stable and efficiency activity for tar steam reforming.

title: Utilizing low grade waste heat in combined-cycle power plant by absorption chiller

description: Performance improvement of a conventional power plant has been received much attention due to energy crisis and global warming problems. Utilization of low-temperature waste heat is considered a promising alternative to enhance the efficiency of power generation. Presently, an absorption chiller has been applied to recover heat from low-temperature energy sources such as bleeding steam and low pressure steam. The aim of this work is to study the use of an exhaust gas from a steam boiler in a power plant, as the low temperature heat source, for an absorption chiller to produce chilled water. Simulations of the absorption chiller process consisting of generator, absorber, condenser and evaporator, were performed using a flowsheet simulator taking into account detailed heat transfer processes. LiBr was represented an absorbent in the absorption chiller. The performance of the absorption chiller process was analyzed. The suitable condition for the absorption chiller operation to recover the waste heat and economic comparison are also identified.

title: Reactive distillation for synthesis of glycerol carbonate via glycerolysis of urea

description: This study developed a new process for synthesis of glycerol carbonate via glycerolysis of urea in reactive distillation using Aspen plus program. Missing thermodynamic parameters (e.g. Gibb’s free energy of formation) of glycerol carbonate were estimated by the group contribution methods including Joback’s, Gani’s and Benson’s methods. The results showed that Gani’s method provided the lowest deviation among the three methods. Equilibrium and kinetic model parameters were obtained from batch experiment and applied to the simulation. A RADFRAC module in Aspen Plus program with equilibrium stage was used in the simulation to investigate the effects of design and operating parameters of reactive distillation on conversion of glycerol and yield and purity of glycerol carbonate. The simulation results showed that high conversion of glycerol could be obtained by increasing the number of stripping and reaction stages as well as decreasing the number of rectifying stages due to reducing reactant loss in the distillate. Moreover, glycerol and urea in distillate were recycled to reactive section by increasing reflux ratio. The suitable design and operating parameters can achieve at 3 stripping stages, 3 reaction stages, no rectifying stage, reboiler heat duty of 15 kW and reflux ratio of 2 – this offers 93% conversion of glycerol, 96% yield, and 100% purity of glycerol carbonate in the final product. Compared to a conventional process, reactive distillation provided higher conversion of glycerol and lower energy consumption.

title: Utilization pattern and controlling system of antibiotics in tertiary care hospital in Nepal

description: Antibiotic policy in many developed countries reported to be successful in reducing the irrational use of antibiotics and antibiotic resistance. The study was aimed to study utilization of antibiotics and to understand the controlling system of antibiotics at tertiary care hospitals in Nepal using Donabedian model of quality of medical care. Combinations of quantitative and qualitative methods were used in this study. Utilization pattern of antibiotics revealed that about 44% and 29% of admitted patients received antibiotics in Western Regional Hospital (WRH) and Manipal Teaching Hospital (MTH) with the mean number of antibiotics 2.25 ±1.14 and 1.84±0.915 respectively. Overall, antibiotic use in WRH (68.45 DDD/100 bed-days) was 3 fold higher than MTH (22.21 DDD/100 bed-days). The mean cost of antibiotics was NRs. 1007.78 ($14) in WRH and NRs. 892.88 ($12.8) in MTH. E. coli showed 100% resistance to Nalidixic acid, Erythromycin, Co-trimoxazole and Cephalexin in WRH. About 40% and 32% of treatment of enteric fever were inappropriate in WRH and MTH respectively. Structure components (Organizational, Personnel, Policy or guideline and Surveillance) were slightly better in the private hospitals than public hospitals because of existence of semi-functional and scattered policy and guideline. Process components were also relatively better in Private hospitals because of good prescribing process and existence of their own hospital pharmacy. The study found the huge communication gap between healthcare professionals on National Surveillance Program and lack of awareness on national drug policy. Hence, we strongly recommend the implementation of antibiotic policy recommended by the expert as well as national drug policy. We also recommend the proper compilation and dissemination of national surveillance data.

title: A serological survey and study on the effects of Caprine Arthritis-Encephalitis Virus infection on reproductive performance of goats in the western part of Thailand

description: During the period from November 2009 to January 2011, a cross-sectional serological survey was carried out in three western provinces of Thailand. A total of 1,129 serum samples from 74 randomly selected goat farms were collected and seroprevalence of antibodies to CAEV infection was determined using competitive enzyme-linked immunosorbent assay (cELISA) test. Semi-structural questionnaires were developed and presented to farm owners. Univariable analysis by Chi-square test was employed to find out the association between CAEV infection and each exposed factor. Multivariable logistic regression model was run to clarify the risk factors. A total of 67 goats (5.9%) were found seropositive with true prevalence of 5.5%. 23 farms out of 74 were found seropositve showing the prevalence of 31%. On herd prevalence, herd type (p = 0.034; OR = 5.026; 95% CI = 1.130-22.360), herd size (p = 0.006; OR = 24.065; 95% CI = 2.466- 234.788), contact with goats from other herds (p = 0.008; OR = 8.526; 95% CI = 1.762 - 41.25), and addition of new goats into herd (p = 0.044, OR = 4.396; 95% CI = 1.044 – 18.51) were observed as risk factors to CAEV infection. On individual prevalence, age of 3 years and above (p = 0.001, OR = 4.288, 95% CI = 1.809 – 10.163), herd size (p&lt; 0.001, OR = 17.971, 95% CI = 7.787 – 41.475), and addition of new goats into herd were detected as risk factors. The results showed that CAEV infection prevailed among the goat herds in the western part of Thailand, with some risk factors to be aware of. A comparative study between two groups of animal, a seropositive and a seronegative group, regarding their reproductive performance in response to CAEV infection was performed in a CAEV seropositive dairy goat farm during the period from January 2010 to February 2011. Average number of offspring born to each group was higher in seronegative group as compared to seropositive group (1.63 vs 1.50). A significantly low (p&lt;0.05) first conception rate was observed in seropositive group, and total conception rate was higher in seronegative group than in seropositve group (82.6% vs 50.0%). Failure to conceive during two consecutive AI was more frequent in seropositive group than in seronegative group (25% vs 13%). These findings suggested some evidence of adverse effects of CAEV infection on reproductive performance of goats and further in-depth studies with greater sample size are deemed necessary to define the influencing effects of CAEV infection on reproduction in goats more precisely.

title: Impacts of the EU’s Emission Trading System on the airline industry : a case study of Thai Airways International

description: This thesis has reviewed the rules and international regulations in relation to the environment with the focus on the European Union in its effort to reduce CO2 emission by presenting issues and possible impacts on the airline industry. The aim is to study the impacts of the EU’s Emission Trading Scheme on the airline industry with specific attention on Asian airlines having flights to, from and within the EU. During the process of analysis existing, pending and possible future regulations were taken into account. Thai Airways International Co., Ltd was used as a case study. Competitive environment in the EU’s airline industry will be analyzed in terms of creating profitability, target customers, demand and other factors that will have effects on the airline’s operations of Thai Airways International. The study uses Porter’s Five-Force model, Value Chain Analysis and the SWOT Analysis to assess the situation in the EU’s airline market and the efficiency of Thai Airways International in the said market. Calculations of profit have been done to assess the changes in operating costs resulting from the scheme on the airline industry. The study has found that: 1) THAI will be able to absorb the extra cost of the regime; 2) the EU ETS seems to have minimal impact on costs and profitability for THAI when compared with other Asian airlines; 3) recommendations for THAI according to the study include reducing operating costs and practicing resource usage efficiency. The conclusion of the thesis is that the impact of the EU ETS scheme on THAI will be quite small.

title: Pre-failure stress-strain behavior and strength of Bangkok Clay

description: Many recent research works have suggested that the stress-strain behavior of soil is highly non-linear and the small strain stiffness of soil is very important for the analysis of the boundary value problems. Although, there are a lot of studies on the behaviors of Bangkok Clay, there is not data on the stress-strain behavior at small- and intermediate-strain level from local strain measurement available at present. This research aims to investigate the stress-strain non-linearity behavior of undisturbed sample of Bangkok Clay with particular attention to its small- and intermediate-strain behavior and also anisotropic characteristic by using the conventional triaxial apparatus incorporating with the local strain measurement systems and bender element system. Both of isotropically consolidated undrained and drained compression tests (CIUC/CIDC) were performed on the vertically and horizontally cut specimens in order to study anisotropic characteristic. Moreover, this research also studies the effects of principal stress rotation and intermediate principal stress on undrained behavior of Bangkok Clay. The results of torsional shear hollow cylinder with various principal stress directions and various magnitude of intermediate principal stress on undisturbed Bangkok Clay are presented. These experimental results should provide further understanding about Bangkok Clay behavior and be also useful for the development of new constitutive models for Bangkok Clay.

title: Effects of serotonin, progesterone and 17ß-estradiol on ovarian development of the black tiger shrimp Penaeus monodon

description: Knowledge on molecular mechanisms of steroid hormones and neurotransmitters on expression of reproduction-related genes may lead to the possible ways to effectively induce ovarian maturation in shrimp. RT-PCR was carried out to examine the expression patterns of several genes. In addition, the full-length cDNAs of 17β–hydroxysteroid dehydrogenase (Pm17β–HSD) of the black tiger shrimp (Penaeus monodon) was isolated and it was 1400 bp in length containing an ORF of 768 bp corresponding to a polypeptide of 255 amino acids. In situ hybridization indicated that Pm17β–HSD mRNA was localized only in the cytoplasm of previtellogenic oocytes but not in more mature stages of oocytes. Recombinant Pm17β–HSD protein (26.78 kDa) was successfully expressed in the bacterial expression system. It was expressed at a very low level as the insoluble protein Quantitative real-time PCR was carried out to estimate the expression of reproduction-related genes in P. monodon. The expression levels of PmATP/GTP-BP and Pm17β-HSD were not differentially expressed during ovarian development in wild intact and eyestalk-ablated P. monodon. However, lower expression levels of these transcripts in stage II and III ovaries in eyestalk-ablated broodstock were found compared to those in intact broodstock (P &lt; 0.05). The expression profiles of PmInx1 and PmPhb2 were similar as they were significantly increased in stages II-IV ovaries in intact broodstock (P &lt; 0.05) and at stages III and IV ovaries in eyestalk-ablated broodstock (P &lt; 0.05). Their expression levels in stages I, II, III and IV ovaries in eyestalk-ablated broodstock were greater than those in the same ovarian stages in intact broodstock (P &lt; 0.05). In domesticated 5-, 9-, 14- and 19-month-old shrimp, the expression levels of PmATP/GTP-BP was not significantly different. In contrast, Pm17β-HSD in ovaries of 19 month-old shrimp was significantly greater than that in other groups of domesticated shrimp (P &lt; 0.05). Injection of 17β-estradiol did not affect the expression level of PmATP/GTP-BP but resulted in a significant increase of Pm17β-HSD at 7 days after injection (P &lt; 0.05). In contrast, progesterone injection resulted in a lower expression of both PmATP/GTP-BP and Pm17β-HSD in ovaries of 14-month-old shrimp at 72 hpi and 24-72 hpi, respectively (P &lt; 0.05). Interestingly, serotonin injection promoted the expression level of PmATP/GTP-BP and Pm17β-HSD in ovaries of 18-month-old broodstock of P. monodon at 6-48 hpi (P &lt; 0.05).
