title: Method development for the determination of antibiotics and antibacterials in cow milk using liquid chromatography-mass spectrometry

description: In this study, a challenging method for simultaneous extraction and determination of six sulfonamides, three tetracyclines, and pyrimethamine residue in cow milk was developed. The sample preparation method include the acidic deprotenization of milk and dechelation by metals with McIlvain buffer, followed by enrichment and clean-up using a co-polymeric solid phase extraction cartridge (SPE), Oasis HLB. Reversed-phase LC-ESI-MS with positive ion mode was used for separation and detection of ten target analytes. Various factors affecting the sensitivity, separation, and extraction efficiency were optimized. Satisfactory recoveries for all compounds were obtained greater than 70%. Estimated method detection limits ranged from 0.48 to 2.64 ng/g which is far below the MRLs regulated by both EU and U.S. FDA. Method quantitation limits ranged from 0.97 to 8.64 ng/g. Linearity (R2&gt; 0.99990) for quantitative analysis was obtained over dynamic range from MQL values up to 300 ng/g. Intra-assay and intermediate precision were acceptable with RSD at MQL and 5-fold MQL levels less than 8.42 and 9.97%. The method demonstrated satisfactory accuracy within an acceptable range of AOAC for trace analysis. The method was found to be robust and showed the pH of sample solution is a critical point for simultaneous extraction all compounds.

title: Pharmaceutical removal by ion exchange process

description: Understanding the interaction of pharmaceuticals with common ion exchange resin used in drinking water treatment plants and sewage water treatment plants is essential to evaluate their routes and behavior in the aquatic environment. The ion exchange of four pharmaceuticals, acetaminophen (ACE), nalidixic acid (NAL), nofloxacin (NFC), and 17-alpha-ethinyl estradiol (EE2), has been investigated in the laboratory using batch experiments at neutral pH range. Anion exchange and cation exchange resins are used as sorbent materials. The preliminary tests showed that acetaminophen, which is in neutral form and has the highest water solubility (14,000 mg/L at 25ํC), was sorbed onto both of ion exchange resins. While nalidixic acid, which has one carboxylic functional group, exchanged with anion exchange resin but no significant ion exchange process with cation exchange resin. Norfloxacin exchanged with both resins. 17 [alpha]-ethinyl estradiol, the most hydrophobic molecule, was similar to acetaminophen, it was sorbed onto anion exchange resin and cation exchange resin. For equilibrium time studies, Acetaminophen on anion exchange resin and cation exchange resin showed that equilibrium was reached within 3 hours. While nalidixic acid on anion exchange resin required 6 hours to achieve the equilibrium. Norfloxacin on both resins reached equilibrium at 1 day. 17 [alpha]-ethinyl estradiol on anion exchange resin and cation exchange resin were used 12 hours and 6 hours, respectively. A Langmuir isotherm was used to fit to ion exchange data of nalidixic acid and norfloxacin but for acetaminophen and 17 [alpha]-ethinyl estradiol were fitted with Linear isotherm. The sorption coefficient and maximum adsorption capacity of nalidixic acid on anion exchange resin were 94 L/g and 1.11 mg/g, respectively. The sorption coefficient of acetaminophen on anion exchange resin and cation exchange resin were 0.0228 L/g and 0.0041 L/g, respectively. The sorption coefficient of norfloxacin on anion exchange resin was 42 L/g and maximum adsorption capacity was 0.93 mg/g, on cation exchange resin, the sorption coefficient was 37 L/g and maximum adsorption capacity was 27.67 mg/g. The sorption coefficient of 17 [alpha]-ethinyl estradiol on anion exchange resin was 0.8096 L/g and on cation exchange resin was 0.0510 L/g. For anion competition studies, sulfate ion competed with nalidixic acid and norfloxacin more than did bicarbonate ion and competition increased with increasing concentration of these two ions.

title: Development and evaluation of lipcare formulations containing rice bran oil

description: The purposes of this study were to select the type and concentration of antioxidant with the highest antioxidant activity in rice bran oil (RBO) and to evaluate the lip conditioning properties of the selected RBO lipsticks in healthy volunteers. The antioxidant efficacy study between tertiary butylhydroquinone (TBHQ) and butylated hydroxyanisole (BHA) under accelerated conditions by 743 Rancimat at 120 degrees celsius were studied. A series of concentrations for each antioxidant was between 0.01-0.10% by weight. The stability of rice bran oil was increased when using higher concentration of antioxidants. TBHQ and BHA have comparable antioxidant efficacy on rice bran oil at levels less than 0.04%. At levels greater than 0.04%. TBHQ is far more effective than BHA significantly (P&lt;0.05). TBHQ at 0.10% by weight was used to stabilize RBO in lipstick preparation. Lipsticks were formulated using oil, fat, and wax. The optimum oil:fat:wax was 76:10:14 by weight. The SPF values of lipsticks measuring by SPF-290s analyzer were increased when using higher concentrations of rice bran oil. Moreover, rice bran oil lipstick showed high efficacy in improving skin-feel, high gloss, good glide and less tackiness. Forty-five healthy female panelists were participated in the study of lip conditioning properties of lipsticks. Lip capacitance, melanin value and hemoglobin value had been measured weekly for 6 weeks. There is no statistical difference among three treatments in all properties. All treatments could increase lip capacitance and hemoglobin value while decrease melanin value significantly with time goes by. Lipsticks containing RBO and lipsticks containing RBO plus [upsilon]-oryzanol induced modest lip conditioning effect compared to control treatment. But lipsticks containing RBO and lipsticks containing RBO plus [upsilon]-oryzanol have comparable efficacy in all properties. The sensory evaluation perceived by panelists informed that lipstick containing RBO plus [upsilon]-oryzanol was evaluated as the most 'satisfy' with its high slipperiness, high gloss, increase moisturizing effect, increase lip redness, decrease lip darkness, and least tackiness.

title: Protective effects of thyroid hormones on atherosclerotic formation in rabbits

description: The objective of this investigation was to study the protective effectives of thyroid hormones on atherosclerotic formation in rabbits. This experiment was performed in twenty-five male New Zealand Whilte rabbits weighing between 2.0-2.5 kg. The animals were randomly divided into five groups, each group containing 5 animals. The rabbit model of atherosclerosis was induced with a period of twelve weeks. Group I, rabbits were fed with standard chow daily. Group II, rabbits were fed with lipid rich food (containing: standard chow, 4% coconut oil, 1% cholesterol). Group III, rabbits were fed with lipid rich food plus propylthiouracil (PTU) at the dose of 20 mg/kg body weight daily. Group IV, rabbits were fed with lipid rich food, 20 mg/kg of PTU, and 50 [microgram]/kg of L-thyroxine (T[subscript 4]) daily. Group V, rabbits were fed with lipid rich food, 20 mg/kg of PTU, and 0.6 [microgram]/kg of Triiodothyronine (T[subscript 3]) daily. Body weight and body temperature were measure weekly. Blood samples were collected for measurements of serum lipid profile, thyroid hormones and lipid oxidation. At the end of the experiment, animals were euthanized and vascular tissues were collected for measurement of histological analysis. Our results showed that animals in group IV had significant decreases in malondialdehydes in plasma and low density lipoprotein (LDL) contents, compared to animals in group II and III. Animals in group IV and V had lower ratio of areas of atherosclerotic lesion and compositions of atherosclerotic lesions, compared to animals in group II and III. In conclusion, the present study demonstrates that thyroxine and triiodothyronine have protective effect by inhibiting atherosclerotic formation in a rabbit model.

title: Hydrodynamics of fluidization of FCC particles and nanoparticles

description: This dissertation describes computational fluid dynamics simulations of the flow of FCC particles in the turbulent fluidization regime, explosive dissemination of 10 nm silica particles and the flow of 10 nm silica particles in a 2-dimensional fluidized bed. In an experimental study flow properties of 10 nm silica particles were determined in a two-story circulation fluidized bed riser. Fluidization of three kinds of silica nanoparticles were also investigated in a 2-dimensional fluidized bed. Computational fluid dynamics (CFD) is a new tool for acquiring the understanding of the hydrodynamics of multiphase flow. However, before this a tool becomes useful for the design purpose, a number of theoretical questions must be answered. This thesis is an attempt to answer some of the unresolved issues.

title: Synthesis of polyimides containing tetraphenylporphyrin moieties

description: 5, 15-Bis(4-aminophenyl)-10,20-diphenylporphyrin (trans-DATPP) was synthesized via the condensation of meso-(4-introphenyl)dipyrromethane and benzaldehyde. The further reaction with zinc acetylacetonate hydrate afforded zinc 5,15-bis(4-aminophenyl)-10,20-diphenylporphyrin (trans-ZnDATPP). The identification of both synthesized compounds and their intermediates was performed by spectroscopic technique. Four series of solube polyimides based on trans-DATPP or trans-ZnDATPP, 2,2' bis(trifluoromethyl)-4,4'-diaminobiphenly (PFMB), 4,4'-hexafluoroisopropylidene-diphthalic anhydride (6FDA) and 3,6-bis(3-trifluoromethylphenyl)pyrromellitic dianhydride (3FPMDA) at various ratios were then prepared. The structures of these polyimides were confirmed by FTIR and 1H-NMR, and porphyrin content in polyimides was determined by UV-vis spectroscopy. It was found that most polyimides containing either trans-DATPP or trans-ZnDATPP had higher viscosity than the polyimidewithout porphyrin moiety. In addition, the polyimides containing trans-ZnDATPP showed lower viscosity and higher glass transition temperature (Tg) than the ones containing trans-DATPP at approximately the same porphyrin content and both had higher Tg than polyimide without porphyrin. These polyimides displayed good thermal stabilities when subjected to thermogravimetric analysis. All polyimides were solube in polar aprotic solvents, THF, CH2CL2 AND acetone. Steady state fluorescence spectroscopy of these polyimides were investigated, electrochemical and time-correlated single photon counting experiments of the representative polymides indicated that these polyimides could be used in photomic applications.

title: Phenomenological supersymmetry

description: A review on the Minimal Supersymmetric Standard Model (MSSM) is given, putting a special emphasis on the Higgs sector. The electroweak symmetry breaking in the context of the MSSM is analyzed. It is found that there are five Higgs bosons in the model, and their tree-level masses are determined. However these masses receive quantum corrections, which can be large if the particles involved in the loop diagrams have large masses. In this thesis, the one-loop correction, due to the top quark and stop squark loops, to the Higgs effective potential is obtained. It is found that such a one-loop correction changes the upper bound on the mass of the lightest Higgs boson substantially with the known value of top quark mass and a sufficiently high supersymmetry breaking scale.

title: Synthesis and attachment of polymide nucleic acid on gold surface

description: Two novel thiol-modified polyamide nucleic acids (PNA) were synthesized by solid phase peptide synthesis and directly attached on gold coated quartz crystals by self assembly monolayer (SAM) formation via S atom for detection of DNA hybridization. The amount of immobilized PNA and the extent of DNA hybridization were detected by quartz crystal microbalance (QCM) which is an extremely sensitive mass sensor. From the result, it can be demonstrated that the amount of immobilized PNA on the gold electrode increased with the PNA concentration. The blocking step is critical to the success of subsequent DNA hybridization. The optimal immobilization condition is PNA concentration: 1.0 M and immobilization time: 24 h and the optimal hybridization condition is DNA concentration: 50 M, sodium phosphate buffer pH 7 concentration: 0.5 mM and hybridization time: 1 h. Moreover, the effect of pH and ionic strength were also investigated. Hybridization of immobilized PNA with perfect matched and mismatched DNA sequences were observed to determine the specificity of hybridization. The QCM results indicated that the binding affinity of PNA immobilized on the gold surface with target DNA is extremely dependent on the nucleobases of PNA and DNA. Finally, single mismatch discrimination has been achieved by a combination of PNA with QCM technique.

title: Geoarchaeology of Thangsetthi, Tambol Nayang, Amphoe Cha-Am, Changwat Phetchaburi

description: Thungsetthi, a locality in Changwat Phetchaburi reveals its archaeological significance in historical period (6-10 C.E.). According to archaeological evidence, it can be assumed that Thungsetthi is situated on one of the ancient communication networks between central and Southern regions of Thailand. The research aims to analyze the relationship among geomorphology, sedimentology an archaeological evidence by using geoarchaeological techniques. The investigation by aerial photographs was the first approach, then, followed by ground reconnaissance and detail field survey. Field work includes geomorphological and archaeological mappings, coring with precision clement sediment corer and test pitting. Laboratory works include the detail log description of sediments, grain size analysis of sediments by laser granulometric technique, and detail analysis in archaeological remains. A result reveals that the change of landscape here has been occurring since the middle Holocene. The propragation of the land in eastward direction can be refereed relatively to the mid-holocene marine regression. Based on the archaeological sites and remains, the Dvaravati habitation site (6-10 C.E.) at Thungsetthi had been located on a beach ridge and barriers close to permian limestone hills and surrounded by aplaeo-channels connecting to the palaeo-shoreline. The progradation of the land during marine regression after the mid holocene might have played a significant role in controlling coastal landform pattern i.e. the change in direction of palaeo-channels. However, the morphological changes of the coastal area have been occurring until the present time. The investigation on coastal stratigraphy supports the evidence about the boundary of palaeo-shoreline. Furthermore, these palaeo-landforms especially beach ridges and sand barriers also represent that the people a Thungsetthi and other Dvaravati sites in adjacent areas selected the innermost sand barrier for their settlements and communication route since this sand barrier was stable and higher than the areas where were close to the shoreline at that time. Moreover, there are some channels that might be used as the transportation way to the sea. According to the archaeological evidence discovered from Thungsetthi, they can be correlated with major Dvaravati communities in central Thailand and suggest the idea that the holocene sand barriers were suitable for using as the communication route during Dvaravati period.
