title: Conductive property of nano silver ink on flexographic prints

description: This research is aimed to study the possibility of applying a flexographic printing with nano-silver ink for fabricating conductive lines on paper and film substrates. The rheological behavior of ink and the varying effects of anilox line screen on printing speeds and print quality were investigated. Printed layer thickness and its resistivity were analyzed. It was found that non linearlty of ink gave little effects on relationships between image parameters and printing conditions. It is because the viscosity of nano-silver ink is much lower than that of common water based flexographic ink. Press setting, packing material and rubber ink fountain roller should be in good conditions to protect printing problems such as ghosting and wave patterning. Results showed that anilox line screen did not relate well to print quality, while higher printing speed rather gave preferable printed results such as better resolution and low spreading, but non-homogeneity of solid area was still existed. The smallest text size which could be produced was 6 pt for positive font and 8 pt for negative font. Anilox line screen 600 lpi and printing speed 60 m/min was proposed as best condition in this study. Image of 0.1 mm finest line with about 10% width spreading and 5 µm thickness was achieved. An average sheet resistivity was at 1.26 ± 0.06 /cm2. This obtained value is a little larger than that of practical RFID devices.

title: Carrying object detection using adaptive centroid star skeleton

description: Detecting a carried object is a primary step for surveillance applications which is useful to recognize and monitor threats, and prevent criminal activity in order to maintain social control. Thus, this thesis aims to detect a carried object seen from a stationary camera using human body silhouette feature information. Star skeletonization technique with the adaptive centroid point is used to extract human feature. The carried object is classified using time series of motions of the extracted skeleton limbs. The boundary of the carried object is figured from carried objects track points and adjacent sink curves of contour. The method is able to detect and track carried object such as a luggage and a backpack. Moreover, the detection of leaving luggage event could be achieved. In the research, some data from TRECVID dataset and manually captured data are used to perform experiments.

title: Constructing Thainess within international food space : Thai gastronomy in five-star hotels in Bangkok

description: This thesis aims at studying the characteristics of Thai gastronomy and analyzing the process of constructing "Thainess" through Thai gastronomy in Thai restaurants located in five-star hotels in Bangkok. Four Thai restaurants in five-star hotels in central Bangkok district (CBD) are selected as case studies. They are 1) Celadon at The Sukhothai Hotel Bangkok, 2) Nahm at The Metropolitan Hotel Bangkok, 3) Sala Rim Naam at The Mandarin Oriental Hotel Bangkok and 4) Spice Market at The Four Seasons Hotel Bangkok. Each of them has its own prominent characteristics and specialization. This research uses a qualitative research methodology through observation and participant observation in the hotel’s culinary practices, interviewing key informants, as well as collecting documents concerning the hotel’s history and culinary management. The research applies Stuart Hall’s concept of the "circuit of culture" as the framework in the analysis of the process of Thai gastronomy. The circuit of culture is composed of five factors: representation, identity, production, consumption and regulation. The research findings reveal that "Thainess" is constructed through three characteristics: firstly, through physical settings and an enhanced atmosphere with Thai art and architecture, both traditional and contemporary; secondly, through a Thai style of service by personnel with politeness and hospitality; and thirdly, through culinary practices. It is also found that Thai values, wisdom and Thai ways of life are selected and presented as the characteristics of Thai gastronomy in each restaurant. It is found that each restaurant selects the identity of Thai food and presents Thainess differently through various components related to Thai gastronomy. Production and the consumption of Thai food is based on the relations, expectations, values and standards mutually agreed between the "hosts" and "guests." The production process also concerns Thai culinary regulations and, given the fact that these Thai restaurants are in an international food space, international standard must then be implemented together with Thainess in the Thai food space. It is further found that the process of constructing meanings and Thainess is very dynamic since these Thai restaurants are situated in the context of globalization, thus, "Thainess" in Thai gastronomy is internationally negotiated.

title: Quinolone resistance via qnrA Integron cassette in Escherichia coli

description: This study determined the characteristics of qnrA genes in Escherichia coli (E. coli) isolated from two hospitals in Bangkok, Thailand (one university hospital and one tertiary private hospital). Polymerase Chain Reaction (PCR) showed a presence of 8 qnrA positive isolates out of 100 extended-spectrum beta-lactamase (ESBL) producing E. coli isolated (quinolone resistant E. coli 83 isolates) from the university hospital, whereas no qnrA was detected in 90 quinolone resistant E. coli isolated from the tertiary private hospital. All qnrA positive isolates associated with the ESBL and class 1 integron (intI1). Double mutations in the quinolone resistance determining region (QRDR) in gyrA (resulted in S83L and D87N) were found in 4 out of 8 qnrA positive isolates. These 4 isolates were resistant to ciprofloxacin, while the isolates without double mutations were still susceptible to this drug. DNA sequencing analysis confirmed positive result for qnrA1. The result from Southern blot hybridization showed that qnrA genes were either located in the chromosome and/or large plasmids (3 out of 8 isolates). This indicated that the qnrA could be integrated into the chromosome via transposon elements along with class 1 integrons. The result of time kill study showed that the qnrA positive isolate indeed conferred low-level resistance to ciprofloxacin and norfloxacin, and they were able to show higher level of fluoroquinolone resistance and increasing the chance of regrowth only when associated with other resistant mechanisms, particularly the mutations in the QRDR (S83L and D87N).

title: Development of high-fiber dried rice noodle from modified rice flour

description: This research aims to determine the effect of citric acid modification on resistant starch content and physicochemical properties of rice flour, and to study the application of the modified rice flour in dried rice noodle. Rice flour was modified by 0.1M citric acid at different reaction temperatures (100, 110 and 120°C) and times (15, 30 and 45 min). The acid treated flour was then incubated at 5, 30, 45, 60, 75 and 90ºC. The resistant starch content and physicochemical properties of native and modified rice flour were measured. Dried rice noodles were produced with replacing rice flour by modified rice flour at 10, 20 and 30% and drying at 50, 60 and 70ºC. Resistant starch content, cooking quality and texture of rice noodle were evaluated. The results showed that the resistant starch content of rice flour increased from 0.65% (native) to 6.51% (acid treated at 120°C, 45 min). Amylose content, solubility and the amylose-lipid complex of modified rice flour were higher than those of the native flour. Treated rice flour at 100°C had higher swelling power, but swelling power decreased at higher condition. The pasting properties of acid treated rice flour showed to decrease in viscosity, breakdown and setback while those treated at the highest condition (120°C, 45 min) exhibited no RVA peak. Whiteness index and relative crystallinity of modified rice flour were lower than the native. The higher reaction temperature and time resulted in greater change in all properties except degree of crystallinity. Rice flour treated at 120°C/45 min was chosen for studying the effect of incubation temperature due to its highest resistant starch content (6.51%). After incubation, the resistant starch content, amylose content, solubility, the amylose-lipid complex, and relative crystallinity of modified rice flour increased with increasing temperature. Modified rice flour incubated at 90°C had the highest resistant starch content (12.41%). Increasing % modified rice flour resulted in higher resistant starch, cooking loss, rehydration, and springiness, but lower in hardness, tensile strength, and cutting force of noodle. The optimum % substitution of modified rice flour at 20% gave noodle having 3.0% resistant starch and the highest sensory score. Drying temperature had no effect on resistant starch content and cooking loss. However, higher drying temperature increased rehydration but decreased tensile strength, cutting force, hardness, and springiness. The suitable drying temperature was 50°C which gave noodle having the highest sensory score.

title: Microtensile bond strength of different types of resin cement to different zirconium-oxide ceramics

description: The objective of this study was to evaluate the microtensile bond strength (MTBS) of different types of resin cement to different brands of sandblasted zirconium-oxide ceramic. Three brands of zirconium-oxide ceramic fully sintered blocks(Cercon, Lava and Katana) ,which surfaces were finished with silicon carbide abrasive and sandblasted with 50µm aluminumoxide particles, followed by ultrasonic cleaning in distilled water for 10 minutes. Zirconium-oxide ceramic were bonded to the same size of resin composite blocks (Filtek Z250) that were finished with the same -grit silicon carbide abrasive and cleaned for 10 minutes in an ultrasonic bath. The ceramic-composite blocks were luted with three different resin cements (Panavia F2, Superbond C&B and RelyX Unicem) according to the manufacturer’s instructions. The ceramic-composite blocks were cut under water coolant to produce microbar specimens, which have bonding area 1 ± 0.1mm2. The microtensile bond strength was tested with universal testing machine at a crosshead speed of 1 mm/min. The broken microbars were examined using a scanning electron microscope (SEM). The MTBS of Lava/Superbond group (53.87 N/mm2) produced the highest MTBS, while Cercon/Panavia group (43.28 N/mm2) produced the lowest MTBS. Type of resin cement and type of zirconium-oxide ceramic have effect on MTBS, while the interaction between zirconium-oxide ceramic and types of resin cement was not significant.

title: Yeast cell-based assay of topoisomerase II inhibitory activity

description: Topoisomerase II (Top2) is an essential enzyme for survival of growing cells. This study aimed to screen ethnomedicinal plants used in Thai traditional medicine for Top2 poison activity using a yeast cell-based assay. Mutant yeast strains carrying the top2-1 allele (JN394t2-1), which encodes a temperature-sensitive topoisomerase, were developed to address the mechanism of action of agents with Top2 poison activity. Six out of thirty extracts; Curcuma longa, C. zedoaria, Derris scandens, Grangea maderaspatana, Stephania pierrei and S. suberosa, were found to have Top2 poison activity against the yeast cells. Further phytochemical studies are needed for the isolation and identification of the natural Top2 poison agents found in D. scandens Benth. (Leguminosae). This is the first time that the Top2 poison activities of D. scandens have been studied. Bioassay-guided fractionation based on Top2 poison activity led to the isolation of two isoflavones from the ethyl acetate extract of the stem of D. scandens. The compounds were identified as 5,7,4'-trihydroxy-6,8-diprenylisoflavone and lupalbigenin from spectral evidence. These compounds showed cytotoxicitiy against human epidermoid carcinoma of oral cavity (KB), breast adenocarcinoma (MCF-7) and human small cell lung carcinoma (NCI-H187) cell lines. In DNA Top2 relaxation assay, 5,7,4'-trihydroxy-6,8-diprenylisoflavone and lupalbigenin also showed inhibitory activity with IC₅₀ values of 24.4 and 8.7 µM, respectively. This is the first time that Top2 poison activity of D. scandens has been reported.

title: Hydrogen production from reforming of glycerol in supercritical water

description: This dissertation investigates different glycerol reforming technologies for hydrogen production. The studies are divided into two parts including i) thermodynamic analysis under thermal neutral gas phase reforming and supercritical water reforming conditions, and ii) experimental studies under supercritical water reforming condition in an Inconel 625 reactor with and without catalysts. Thermodynamic analysis by Gibbs minimization indicates that the thermal neutral condition can be achieved when water to glycerol ratio (WGR), oxygen to glycerol ratio (OGR), and operating temperature are carefully selected. The reformer level shows that only a small amount of OGR is required in the operation. Much higher OGR is required to provide sufficient energy especially for the feed preheating in the system level. Considering two modes of air feeding in the System level, the Single-feed mode is a superior mode in term of suppressing carbon formation _ no carbon formation is observed when operating at temperature above 900 K. The Split-feed mode offers higher H2 mole fraction in the product gas because N2 from air and part of CO2 are not present in the gas product in the Split-feed mode unlike in the Single-feed mode. Use of pure O2 in the Single-feed mode can increase the H2 mole fraction in the product and H2 yield. In addition, using the afterburner products stream to supply heat is beneficial to increase the H2 yield in the Split-feed mode as it decreases the fuel requirement (glycerol and air). Thermodynamic calculations of the supercritical water reforming indicates that higher operating temperature, lower pressure, and lower glycerol feed concentration promote hydrogen production. CO is almost inhibited at high pressure, achieving less than 0.01 of mole fraction. Above 1048 K, only slight change of components is found by increasing of operating temperature. The experimental results in the empty Inconel 625 reactor show that conversion of glycerol and hydrogen yield increases when increasing the operating temperature. However, carbon formation is found as a serious problem for low and medium feed rates at high operating temperatures. Lower feed glycerol concentration supports the hydrogen production without carbon formation. For the catalytic supercritical water reforming, cobalt and nickel metals with the La2O3, ɤ-Al2O3, α-Al2O3, ZrO2, and YSZ supports are chosen. Co/YSZ and Ni/La2O3 catalysts are found to be suitable catalysts in terms of glycerol conversion, hydrogen yield, and carbon formation at 773 and 798 K, respectively. The metal loading is an important parameter to enhance the hydrogen production. The optimum cobalt and nickel loadings are 10 and 15 wt.%, respectively.

title: Characteristics and catalytic properties of silica-supported Zirconocene/MAO catalysts for ethylene polymeriztion

description: Nowadays, the metallocene catalysts activated by methylaluminoxane are used in the synthesis of polyethylene because they give the high activity in ethylene polymerization. However these systems also have some big disadvantages such as the lack of morphology control. So, they need an excess amount of methylaluminoxane (MAO), which is very expensive. To overcome this drawback, the matallocene catalyst has to be attached on the support and also can be used in the slurry or gas-phase. In this research, silica as a support for metallocene catalyst system was studied. These studies were divided into two parts. In the first part, the copolymerization of ethylene/1-hexene with various the 1-hexene amount was investigated. The silica used in this part is in-house silica and the in situ impregnation was used in this part. It was found that when the amount of 1-hexene increased, the catalytic activity also increased. For the second part, the ex situ impregnation of methylaluminoxane on the commercial silica by varying the amount of methylaluminoxane was investigated. It can be seen the amounts of [Al]MAO on the commercial silica increased with increasing the amount of methylaluminoxane.

title: Immunomodulatory effects of piper nigrum extract on macrophage cell J774A.1

description: Piper nigrum (P. nigrum) or black pepper is one of Thai herbs which has been used both as seasoning and traditional medicine. This plant has healing properties in relieving flatulence or dyspepsia. P. nigrum composed of several phytochemical compounds. Preliminary study showed that the water extract of P. nigrum stimulated nitric oxide (NO) production in macrophage cells. NO is one of inflammatory mediators using for host defense mechanism. The present study then aim to investigate the immunomodulatory effects of the water extract of P. nigrum on macrophage cells. The results showed that the water extract of P. nigrum at concentration of 3.125-100 µg/ml increased phagocytosis by macrophage cells. Moreover, P. nigrum has stimulatory effect on NO production. NO is an important molecule involved in destruction of microbes. Furthermore, this extract at 12.5-50 µg/ml also increased the expression of inducible nitric oxide synthase (iNOS), the enzyme which catalyzes NO production. In part of oxygen-independent pathway, the water extract of P. nigrum promoted the production of lysozyme M, the enzyme capable of hydrolyzing bacteria. The extract at 50 µg/ml also enhanced the expression of Dectin-1 receptor, the receptor which recognizes fungal cell wall. The water extract of P. nigrum at 12.5-50 µg/ml promoted the expression of the pro-inflammatory cytokines including IL-1β, IL-6 and TNF-α. Furthermore, the water extract also enhanced the expression of costimulatory molecules necessary for T cell activation including B7-1, B7-2 and ICAM-1. This study suggests that the water extract of P. nigrum is ability to stimulate macrophage functions which involve in immunomodulation. It may be benefit in developing new drug and also ensuring the efficiency of Thai herb.
