CONSUMPTION,ONLINE SOCIAL NETWORKING,AND SUBJECTIVE WELL-BEING IN COSMOPOLITAN BANGKOK

This thesis studies the determinants of subjective well-being, with the main focus on types of consumption, including material, experiential, and online social network (OSN) goods. Friendship types, particularly virtual friends, are also examined, given social changes in today’s digital age. In addition, the feeling of debt burden associated with OSN goods is explored. The study uses cross-sectional data from a survey in Bangkok (n=500) collected in February and March 2015. Subjective well-being functions are estimated...

ARI: THE DYNAMICS OF CONTEMPORARY URBAN CHANGE IN A BANGKOK NEIGHBORHOOD

Jonas Hove Doctor
In urban settings in the West, emerging neighborhoods are often viewed as products of residential and commercial gentrification: the influx of creative and/or affluent populations and new entrepreneurial retail capital into poorer, working class communities. While residential and commercial gentrification can significantly upgrade a neighborhood’s status and image within the wider context of the surrounding city, the process is often criticized for leading to the displacement of the neighborhood’s original population and the closure of...

EVALUATION OF NITROGEN-FOAM FLOODING IN MULTILAYERED HETEROGENEOUS RESERVOIR

Seema Tarannum Shaikh
Most oil reservoirs yield early high water cut due to heterogeneity, resulting in poor sweep efficiency and consecutively inefficient oil recovery. Selection of proper Enhanced Oil Recovery (EOR) technique is therefore top priority and prime concern is to control mobility of water and gas. Foam flooding is one of the techniques that can increase macroscopic sweep efficiency in heterogeneous reservoir. In this study, injection of nitrogen-foam is performed in multi-layered heterogonous reservoir. Reservoir model is...

HIERARCHICAL SILVER NANOSTRUCTURE FROM HYDROGEN PEROXIDE-REDUCED SILVER ACETATE

Ag microstructures were synthesized with a reaction between silver acetate (CH3COOAg) and hydrogen peroxide (H2O2) without surfactant or capping agent under ambient condition in 2 min. They were characterized with spectroscopy techniques. Ag microstructures showed dendritic pattern on their surface with single crystal XRD pattern. Rate of the reaction plays an important role on structural control. Acetate ion spontaneously binds with Ag surface and organic solvents with the other end. Ag microstructures were also controlled...

FIRST-PASSAGE TIME SECURITIES VALUATION UNDER JUMP-DIFFUSION MODEL USING PARTITIONING, EXPONENTIAL TWISTING, AND CONDITIONAL MONTE CARLO TECHNIQUE

This paper develops an efficient simulation-based method to price derivative securities whose payoff depends on a first-passage time and the value of its underlying at that time, under the assumption that the underlying’s process follows the jump-diffusion model. Because of the high variation of payoff and the rarity of the first-passage event, pricing such securities using Monte Carlo simulation is challenging, and usually results in a price estimate that has high variance. As a solution,...

GENETIC ASSOCIATIONS OF SOW LONGEVITY WITH AVERAGE DAILY GAIN AND BACKFAT THICKNESS

Data collected from 2,865 removed sows (1,706 Landrace and 1,159 Yorkshire) in a Thai swine breeding herd from 2008 to 2013 were used to estimate the heritability and genetic correlations among sow longevity, average daily gain, and backfat thickness. Sow longevity was determined as the number of days from first farrowing to removal dates. Estimation of variance and covariance components were carried out with multiple – trait animal models using restricted maximum likelihood (REML) method....

Pathology and molecular characterization of feline parvovirus isolated from small Indian civets (Viverricula indica) in Thailand

Feline panleukopenia virus (FPLV) infection has been reported frequently in both domestic and wild Felidae more than half of century. Other wild carnivores such as Viveridae have reported rarely with FPLV infection. In September 2013, fifty-five small Indian civets (Viverricula indica) were raised in an opened system farm in Trat province, Eastern Thailand. Initially, two of them died with bloody diarrhea, vomiting, associated dehydration and seizure. Consequently, the mortality rate of this outbreak was increase...

MICROPROPAGATION AND CAMPTOTHECIN PRODUCTION OF OPHIORRHIZA HARRISIANA BY TEMPORARY IMMERSION BIOREACTOR

Ladda Techawiriyathaweesin
Ophiorrhiza harrisiana is a plant which produces camptothecin (CPT) in its roots and leaves. CPT is a precursor in the synthesis of chemotherapeutic drug. Since this plant is an herb that is found in particular location and season, conservation and propagation of this plant species are needed. The objectives of this study were to propagate the plant in two tissue culture systems including conventional method (CM) and temporary immersion bioreactor (TIB), and to study its...

THE EFFECTIVENESS OF INTENSIVE HEALTHCARE WASTE MANAGEMENT MODEL (IHWMM) REGARDING INFECTIOUS HOSPITAL WASTE AT TERTIARY CARE HOSPITALS OF RAWALPINDI PAKISTAN

Ramesh Kumar
Infectious waste management has always remained a neglected public health problem in the developing countries, resulting in high burden of environmental pollution affecting general masses. Health workers are the key personnel who are responsible for the management of infectious waste at any hospital, however, their proper training and education is must for an optimal performance. This interventional study was conducted to assess the effectiveness of Intensive healthcare waste management (IHWM) training model at two tertiary...

Estimation and Analysis of Multivariate Jump Diffusion Models with Jump Clustering and Contagion Effects

Extreme negative equity return across markets during financial crisis is one of the main concerned topics in the financial world. When such unexpected events occur, the adverse effect tends to trigger further losses and spreads over to other markets. This research develops a novel financial model that tries to capture these jump clustering and contagion effects. The model is developed to handle a large number of assets. Based on empirical evidence on developed and emerging...

DECEIVED INTO THE FISHING INDUSTRIES: CASE STUDIES OF TRAFFICKED CAMBODIAN WORKERS

This thesis examines the Cambodian seafarer’s experiences of trafficking in persons for the purpose of forced labor and exploitative working conditions on fishing vessels. It also investigates the victim identification procedures implemented by operational authorities, and documents victim reintegration programs supported by government and non-governmental organizations prior to and following repatriation for trafficked/exploited victims. Cambodian migrant workers are vulnerable to trafficking in persons as a result of irregular recruitment practices and lack of effective control,...

DYE-SENSITIZED SOLAR CELLS WITH TiO2 ELECTRODE MODIFIED BY La2O3, Er2O3 or AgO

Tanya Jakawanorasing
In this research, we modified TiO2 electrode of a dye-sensitized solar cell (DSSC) by adding the second metal oxide, namely lanthanum oxide (La2O3), erbium oxide (Er2O3) and silver oxide (AgO). Moreover, we also investigated the addition of light scattering layer in the electrode by employing double layered structure. TiO2-based mixed oxides were synthesized via sol-gel methods. The mixed oxide sols were then coated on a conducting transparent glass as thin film using an ultrasonic spray...

DESIGN OF A REACTIVE DISTILLATION COLUMN FOR GLYCEROL ETHER PRODUCTION

Biodiesel, an important alternative energy, is generally produced from a transesterification reaction of vegetable oils and alcohol. This reaction always generates crude glycerol as by-product. As a result, the utilization of crude glycerol to produce higher value-added products can increase the competitive potential of biodiesel producers. In this research, the production of di and tri tert-butyl ether of glycerol (known as glycerol ether) from etherification of glycerol and tert-butyl alcohol is studied. Due to the...

DOPING OF CeO2 IN V2O5-TiO2 CATALYST FOR LOW-TEMPERATURE SELECTIVE CATALYTIC REDUCTION OF NITROGEN OXIDE BY AMMONIA

This research investigated the selective catalytic reduction of NO by NH3 over V2O5-CeO2/TiO2 catalyst at low temperature. Formation of nitrogen oxide from the ammonia oxidation reaction and SCR reaction was also investigated. Titanium dioxide support was prepared by a sol-gel method. Then vanadium and cerium were deposited via an incipient wetness impregnation method. The amounts of vanadium and cerium in the catalyst ranged from 1 to 7%wt and 5 to 30%wt, respectively. The catalysts were...
