title: Effect of surfactants on the formation of chitosan nanoparticles

description: The effects of surfactants on the formation of chitosan nanoparticles were studied. The high, medium and low molecular weight chitosan (Mv~10[superscript 6], 1.5x10[superscript 5] and 10[superscript 4]) were mixed with the evaluated surfactants in micellar system under different mixing techniques : stirring, ultrasonicating and vortexing. Only the aniomic surfactants, sodium bis(ethylhexyl) sulfosuccinate (AOT) and sodium dodecyl sulfate (SDS) allowed the formation of chitosan nanoparticles in aqueous media. At the chitosan concentration of 2.5 mM the formation of nanoparticle was observed when the mole ratio of surfactant/chitosan was higher than 14:1 and 20:1 for AOT and SDS, respectively. The size and zeta potentials of the particles determined by photo correlation spectroscopy and zetasizer were 110+-10 nm and -47.42 +- 5 mV, respectively. The chitosan/AOT nanoparticles obtained can be loaded with tetracycline at AOT/chitosan/tetracycline mole raio of 20:1:1 with 50% entrapment efficiency. The suspensions of the chitosan/AOT nanoparticles were stable at ambient condition for at least 30 days.

title: Geologic structures of the low-grade metamorphic terrane, Chon Buri coastal area, Eastern Thailand

description: A low-grade matamorphic terrane along Chon Buri coastal area from Sri Racha to Sattahip, regionally consisting of fine-grained clastic sediments and carbonate rocks of Carboniferous-Permian age, was studied. These rocks were intruded by a Triassic granitic pluton that exposes and marks the eastern limit of the study area. The purpose of this study is to clarify the geologic structure and deformation phases using a structural analysis. The detail study here reveals three deformation episodes and two metamorphism events. The oldest deformation (D[subscript 1]) which accompanies a dynamothermal metamorphism (M[subscript 1]) is recognized by the elongate tight-to-isoclinal folds with fold axial planes being inclined moderately to the west and the axes trended somewhat north-south to northeast-southwest with crossed extensional joints and mormal faults. The microscopic study of c-axis of quartz grains in four orientated thin sections of quartz tectonite also shows a preferred orientation with a point maximum that conform these fold axes. The second deformation (D[subscript 2]) formed the NW-SE cross folds superimposing on the previous folds thus resulted as type-1 interference pattern of Ramsay (1967). This interference folding episode may occur together with, or being shortly followed by a granitic intrusion in Triassic and caused a thermal metamorphism (M[subscript 2]). The last deformation (D[subscript 3]) caused a low-angle reverse faulting which brought the metamorphosed stratified units to overlie the non-metamorphosed younger igneous body. The age of this faulting is inconclusive, though thought to be Middle-to Late Mesozoic or very early Tertiary judging from the unaffected Tertiary alluvial-fan unit lying further to the east.

title: Ground state of E[subscript g] electron in the spinless hubbard model

description: The ground-state properties of a simple model for transition metal oxide compounds in ferromagnetic phase have been studied. This model only contains the orbital degree of freedom. The two-orbital spinless Hubbard model in the limit of strong on-site coulomb interaction (U) has been used to describe the motion of election in e[subscript g] orbital. In the large-U and half-filling limits, the effective Hamilto-nian has been derived from the Hubbard model by the canonical transformation. After the transformation, the doubly occupied states have been projected out and the size of the Hillbert space has been reduced. For this effective Hamiltonian, the hopping amplitudes have been defined according to the managanite system which consists of three axes: x-, y- and z-axis. Since the ground-state properties of the effective Hamiltonian have been calculated only in one-dimension, then the results of this work have been separated in three cases; the electrons hopping in x, y, and z axes respectively. The ground-state wavefunction of this effective Hamiltionian has been calculated by infinite density matrix renormalization group algorithm. This algorithm leads to the ground state at the thermodynamic limit when the number of sties is large. It has been found that the ground-state energies are equivalent in all hopping axes. Furthermore, the nearest neighbor orbital correlations at the ground state for all axes are antiferro-orbital.

title: Enhancement of competitiveness for compact car production

description: Established an efficient strategy and method for an automobile company in order to enhance the competitiveness for the compact car production in high competitive market. Presently, surveys, qualitative research and quantitative research are the broadern-accepted tools to find out the customer's needs. However, the automobile company still can not reach their goal to develop their product to meet their customer's requirements by using these particular tools. Therefore, the initial process, building success in developing product, is to establish an efficient strategy and method that be able to find out what the customer really needs. The research started with the analysis of finding the appropriate strategic approach or method in order to apply to enhance the competitiveness for the compact car production. In order to solve this problem, the Kano model can help to define the level of customer's desire in each product feature. However, the problem also comes when using the original Kano model, the customers definitely choose all adding product features without thinking about any increasing cost. Therefore, in order to solve this problems and improve the method to be more effective, the Kano model needs to be modifined by adding price factor into the questionnaire. Next procedure, in creating Kano Questionnaire, the primary data of product features is collected from comparing Toyota Corolla, used as a based model, with its competitors and upper classes. Therefore, potential product features that might be fallen in Must-be, One-dimensional, Attractive requirements or else are found. After using modified Kano Questionnaire to analyze all product features, the appropriate product features have been chosen to be equipped into 3 appropriate classes of products' line-up in order to match with the variety of customers' desire. This research has introduced new strategic approach and method by using the modified Kano Model, which is proved to be one of effective tools and guideline to enhance the competitiveness for the compact car production in the future.

title: Synthesis of the rotenoids 6-deoxyclitoriacetal isolated from roots of Stemona collinsae Craib. and cytotoxic activity against cancer cell lines

description: The total synthesis of 6-deoxyclitoriacetal (39), a cytotoxic natural product, has been achieved by using PtCl[subscript2]-catalyzed hydroarylation, Sharpless asymmetric dihydroxylation, IBX regioselective diol oxidation and stereoselective intramolecular keto-aldehyde pinacol coupling as the key steps. The important steps of this synthesis began with the conversion of compund 1,2-dimethoxy-4-prop-2-ynyloxybenzene (75) into 6,7-dimethoxy-2H-chromene (83) using PtCl[subscript2]-catalyzed hydroarylation reaction successfully in good yield. The Sharpless asymmetric dihydroxylation of compound 83 provided a diol 84 which was converted into 3-hydroxy-6,7-dimethoxy-chroman-4-one (82) by selective oxidation with IBX in EtOAc. Conversion of [alpha]-hydroxy ketone 82 to a good leaving group, Tf (86), leaded to connection of D ring and A-B ring which was convinced by S[subscript N]2 reaction in very good yield (80%). The C ring was formed by SmI[subscript2]-promoted intramolecular Pinacol-type cyclization of 2-(6,7-dimethoxy-4-oxo-chroman-3-yloxy)-6-hydroxy-4-methoxybenzaldehyle (87) which was delivered the right stereogenic center at C 12a. Finally, completed synthesis of 6-deoxyclitoriacetal (39) was achieved by oxidation of 2,3,9-trimethoxy-6,6a-dihydro-12H-chromeno[3,4-b]chromene-11,12,12a-triol (88) with MnO[subscript2]. The compound 39 exhibited cytotoxic activity against human breast carcinoma (BT474), lung carcinoma (CHAGO), hepato carcinoma (HEP-G2), gastric carcinoma (KATO3) and colon carcinoma (SW620) at IC50 0.2, 0.9, 0.1, 0.3 and 0.1 [microgram]/mL, respectively.

title: Iron pelletization with various seeding materials

description: Recently, zero valent metals process was widely used for chemical treatments such as nitrate removal because this process is higher efficiency at low cost and leads to non-toxic waste. Nevertheless, the large amounts of iron were produced from zero valent metal process. This research approached this problem by coating iron oxide onto the surface of quartz sand in fluidized bed reactor which could reduce sludge volume significantly due to denser property of the pellet compared to puffy sludge. This study attempts to utilize several seeding materials as the media in the fluidized bed process for ferrous removal. Additionally, aeration and fenton pretreated were varied for changing ferrous to ferric ion was concentrated for process comparison. The result from fenton pretreated iron coated sand (F-ICS) showed that higher amount of iron tends to attach on the sand surface at pH 6.5. The recirculation rate was also found to affect iron precipitation in fluidize bed and the optimum flow rate was 2,100 mL/min (0.5 bed expand). Sand of 400g/L was found to be sufficient to remove 98% of 185 mg/L of total iron within 2 hr which provide specific coating capacity 0.456 mg/g. Iron coating ability of F-ICS seems to be diminished when reused repeatedly with the iron accumulation of 3.56 mg/g sand at the 11th cycle. While, three phase fluidized bed process was achieved at 20 mL/min which produce coating capacity 0.431 and 0.417 mg/g for quartz sand (T-ICS) and aluminum oxide 9T-ICAO) respectively. The results indicated the iron pellets obtained from three phase fluidized bed process have more stable at wider pH range. The adsorbed ability of iron pellets for the removal of copper were explained by Langmuir adsorption isotherm which provide a maximum adsorption capacities 0.249, 0.300 and 0.222 mg Cu/g for F-ICS, T-ICS and T-ICADO respectively. SEM and EDX spectrum reported that percent of iron occurred following iron pelletization process and copper became one of the principle elements on the surface of iron pellets after adsorption process.

title: Supplementary Material for: Prognostic Significance of Hyponatremia in Acute Stroke: A Systematic Review and Meta-Analysis

description: <b><i>Objective:</i></b> Hyponatremia is a common electrolyte disorder in patients with stroke, which leads to various fatal complications. We performed a systematic review and meta-analysis to investigate the outcomes of acute stroke patients with hyponatremia. <b><i>Methods:</i></b> We searched MEDLINE, EMBASE, and the Cochrane Library databases for relevant literature in English published up to March 2020. Two review authors independently screened and selected the studies by assessing the eligibility and validity based on the inclusion criteria. Mortality at 90 days was set as the primary end point, and in-hospital mortality and length of hospital stay were set as the secondary end points. We conducted the data synthesis and analyzed the outcomes by calculating the odds ratio (OR) and mean difference. <b><i>Results:</i></b> Of 835 studies, 15 studies met the inclusion criteria (<i>n</i> = 10,745). The prevalence rate of stroke patients with hyponatremia was 7.0–59.2%. They had significantly higher 90-day mortality (OR, 1.73; 95% confidence interval (CI), 1.24–2.42) and longer length of hospital stay (mean difference, 10.68 days; 95% CI, 7.14–14.22) than patients without hyponatremia. Patients with hyponatremia had a higher tendency of in-hospital mortality than those without hyponatremia (OR, 1.61; 95% CI, 0.97–2.69). <b><i>Conclusions:</i></b> The development of hyponatremia in the clinical course of stroke is associated with higher short-term mortality and a longer hospital stay. Although the causal relationship is unclear, hyponatremia could be a significant predictor of poor outcomes after stroke.

title: Coastal erosion at the Pak Phanang River Basin Changwat Nakorn Si Thammarat

description: Coastal Erosion at Pak Phanang River Basin: Changwat Nakorn Si Thammarat has generally experienced the problem of shoreline erosion and it has been a continual occurrence for 30 years as the result of many elements. This thesis aims to evaluate of the characteristics of waves, currents, and longshore transport in the nearshore zone of the Gulf of Thailand as well as the historical changes of the shoreline at the Pak Phanang areas. Shoreline comparison in the years 1975, 1995 and 2002, shoreline changes during each period. The study results revealed that there were changes of the Pak Phanang shoreline especially in the period of 1995-2002. In the period of 1975-1995 the highest erosion area was found at Ban Plai Sai which had an approximate erosion rate of 6.84 m/year. In the period of 1995-2003, the high rate of erosion (more than 10 m/year) from this study was found at Ban Plai Sai. It had an approximate erosion rate of 11.3 m/year and Ban Nam Sup had an approximate erosion rate of about 10 m/year. The most severe erosion, about 6-8 m/year during 1995-2002, had occurred at the shoreline between Ban Ko Fai to Ban Nam Sap. This study illustrates collected data relayed to estimate the critical urgent problem areas. The prioritization method of shoreline protection analyses outline the rate of erosion overlaid with layer of landuse, layer of economic-social index, layer of economic loss value and layer of existing shoreline protection measures. The area of ultimate urgency is in the Ban Kong Kong. This area has proved to be high priority due to evident erosion.

title: Development of multivariate curve resolution program based on self-modeling techniques for chemical applications

description: A technique for characterization of multi-component system has been implemented. The program SMCR version 1.0 was developed to resolve the UV-visible spectra and chromatogram. The program resolves spectra into concentration and absorptivity profiles of significant components using self-modeling curve resolution techniques based on Orthogonal Projection Approach (OPA), Simple-to-use interactive self-modeling mixture analysis (SIMPLISMA) and Evolving Factor Analysis (EFA) methods. The program was developed in MATLAB version 6.5 (MathWorks, Inc.). The efficiency and validation of the program were performed with simulated spectra in acid-dissociation, metal-ligand complexation and chromatographic systems. The resolved concentration and absorptivity profiles from three methods are in good agreement with the presetting values. The EFA method gives the best results of three methods. The program was later used to resolve the experimental spectra of two-step reaction between 3-chlorophenyl-hydarzonopropane dinitrial and 2-meracaptoethanal and copper-glycine and copper-alanine complexation systems. The concentration profiles of these systems are in good agreement with previous studies.

title: Effects of medium chain fatty acids, organic acids and fructooligosaccharide on cecal salmonella enterica serova enteritidis colonization, physical and biological changes of intestine in broiler chicks

description: The objective of this investigation was to study the effect of medium chain fatty acids, organic acids and fructooligosaccharide on cecal Salmonella enterica Serovar Enteritidis colonization, physically and biological changes of intestine in broiler chickens. Six hundred day old chicks were allocated into 4 treatments. The treatments were CON: broiler chicks were received basal corn-soybean meal diet. FOS: broiler chicks were received basal diet supplemented 4 g/kg fructooligosaccharide, ORA: broiler chicks were received basal diet and given tap water supplemented with mixed organic acids at 1:1,000 continuously until the end of experiment, MCA: broiler chicks were received basal diet and given tap water diluted with medium chain fatty acids 1:1,000 continuously from start until 35 days and 1:2,000 until the end of experiment, All chickens were inoculated with S.Enteritidis 0.3 ml is culture 10[superscript 6] cfu/ml at day 3 and 1 ml of 10[superscript 8 cfu/ml at day 13 post-hatching. At days 21, 35 and 45 of age, body weight and feed intake were recorded. Cecal samples were examinated of S.Enteritidis colonization. In situ pH determination in crop small intestine and ceca were measured. Jejunal mucosal samples were collected for the determination of disaccharidases. Iileal digesta were collected for nutrients digestibility using the marker technique. Cecal contents were collected for determination of short chain fatty acids (SCFAs) and medium chain fatty acids (MCFAs). Plasma samples were collected to determine medium chain fatty acids. Forl the overall period (day 1-45 of age), chicks in MCA and ORA groups had significantly (p&lt;0.05) higher average daily gain and better feed conversion ratio than CON group. Chicks in MCA, ORA and FOS group had significantly (p&lt;0.05) higher body weight than CON group. Chicks in MCA and ORA group showed the reduction of S.Enteritidis in the ceca which was significantly (p&lt;0.05) lower than CON group. Chicks in MCA, ORA and FOS group had significantly (p&lt;0.05) lower pH of crop and intestine than CON group. Chicks in MCA group had significantly (p&lt;0.05) higher disaccharidases enzyme, digestibility of nutrients, SCFAs (acetic acid and valeric acid), MCFAs in plasma than CON group. In conclusion, chicks in MCA and ORA group had better growth performance, less S.Enteritidis colonization and pH in crop and intestines. Chicks in FOS group tended to decrease Salmonella colonization in ceca. The chicks in MCA and FOS group increased sucrase activity. Moreover, chicks in MCA group were found MCFA concentrations in plasma, increased SCFAs concentrations in ceca and nutrients digestibility.
