title: Grafting of p-Methoxy cinnamic acid on chitosan

description: In this work, UV-filtering polymer was synthesized by grafting of UV- absorptive chromophore onto chitosan. The synthesis process involved 1) reacting chitosan with phthalic anhydride to give phthaloylchitosan that could be soluble in organic solvent such as DMF and 2) esterifying between 4-methoxycinnamic acid and/or 2,4,5-trimethoxycinnamic acid with the phthaloylchitosan. The three obtained polymeric chitosan derivatives, 4-methoxycinnamoyl-phthaloylchitosan, 2,4,5-trimethoxycinnamoyl-phthaloyl chitosan and 2,4,5-trimethoxycinnamoyl-4- methoxycinnamoyl-phthaloylchitosan showed UVB, UVA and both UVA and UVB absorption properties, respectively. Moreover, all three polymeric chitosan derivatives were photostable. Experiments using baby mice skin revealed that all three polymers could not penetrate the baby mice skin.

title: Comparative study of implementation of online bidding for contractor selection in government construction projects

description: Online bidding is now used in construction material procurements as well as in infrastructure projects tendering. This paper explores the current practices of online bidding in four Southeast Asian countries; Indonesia, the Philippines, Singapore and Thailand, especially for government construction projects. This paper aims to compare the practices in each bidding stage: bid invitation, document preparation, bid submission, pre-qualification, e-bidding process, winner selection, as well as contract award. The research outcome is expected to be an information exchange among these countries. Literature review from previous research was conducted to determine the major factors influencing online bidding implementation method. Interviews then were conducted to the government as system’s regulator, to the computer system providers, as well as to the users and the bidders to discover the benefits and obstacles of online bidding they experienced. System trials were also performed in Indonesia and the Philippines. A system is then proposed to accomplish the research objectives and address problems found from the observations. Registration process should be able to record history of contractor performance. Technical Service Provider should be under government so that it is easy to be monitored. Bidding should be conducted electronically to eliminate obstacles due to time and place. It also saves cost of preparing paperwork for both government and contractor. Moreover, electronic processes avoid direct contact among bidders so that possibility of making bid price arrangements among bidders is lessened. Training is important to adjust habitual changing from paper-based to computer-based practices. Accordingly, existing laws should also cover legal matters related to the use of digital media.

title: Alteration in the activity of MAPKs in primary sensory neurons and associated glial cells in paclitaxel-treated rats

description: Paclitaxel (Taxol®), an effective anti-neoplastic agent in the treatment of several solid tumors, produces a peripheral neuropathy with sensory predominance as one of its toxic side effects. Little is known regarding the mechanisms underlying this complication. Mitogen-activated protein kinases (MAPKs), a family of serine- threonine specfic kinase comprised of extracellular signal regulated kinase (ERK), c- Jun NH;-terminal kinase (INK) and p38 kinase, have been shown to be activated in neuronal and other cell types in response to paclitaxel. Therefore, this work was aimed to study the activity of all three subfamilies of MAPKs in primary sensory neurons and glial cells in the animal model of paclitaxel-induced neuropathy. Adult male Wistar rats were given a weekly intraperitoneal injection of 16 mg/kg paclitaxel (P group) or vehicle (Cremophorrethanol, V group) for 5 consecutive weeks and were subjected to quantitative sensory tests and nerve conduction velocity (NCV) study. Prolonged reaction time to the heat at the tail and hind paw including reduced tail NCV was observed, indicating the neuropathy. Subsequently, the animals were sacrficed and L4~5 dorsal root ganglia (DRG) were removed for Western blot analysis. The immunoblots showed an insignficant increase in the phosphorylation of ERK in the DRG of paclitaxel-treated rats compared with those of the controls. Similarly, an insignficant activation of p38 was demonstrated in the V and P groups relative to the controls. For JNK, comparable levels of phosphorylation in all groups were observed. It cannot be concluded that there is no change in the activity of MAPKs in DRG in response to paclitaxel until further studies in various time points are completed.

title: Liquid-phase microextraction using hollow fiber membrane for determination of disinfection by-products in water

description: Liquid-phase microextraction (LPME) with gas chromatography-electron capture detector (GC-ECD) has been developed for extraction, preconcentration and determination of trihalomethanes (THMs) and haloacetic acids (HAAs) in drinking water and tap water. THMs were directly extracted from 10 mL water sample by LPME using 1-octanol as extracting solvent at 35 °C for 30 min. HAAs were in-situ derivatized in 10 mL water sample by esterification with acidic methanol at 55 °C, followed by headspace extraction and concentration with LPME for 60 min. The proposed methods provided high enrichment factor up to 62 fold. The linearity ranges of both THMs and HAAs with correlation coefficient &gt; 0.9904 were obtained. Relative standard deviations were below 12 %, and the method detection limits (MDL) were at sub µg/L levels, which were lower than previously studied such as headspace, solid-phase microextraction and single-drop microextraction. Moreover, MDL are also lower than the maximum contamination level (MCL) values of WHO, EU and US EPA regulations. Application of these methods to water samples from Chulalongkorn University was performed. The results from survey water samples showed that the concentrations of THMs and HAAs were within the permissible level allowable by WHO, EU and US EPA regulations.

title: Short chain branching distribution of LLDPE by tref and NMR

description: In this study, a preparative temperature rising elution fractionation apparatus (TREF) was constructed. Three commercial grade LLDPE samples, i.e. ethylene/l-butene copolymers (C₄-LLDPE), ethylene/1-hexene copolymers (C₆-LLDPE), andethylene/l-octene copolymers (C₈-LLDPE) were fractionated by this TREF. Solvent type and cooling rate in the crystallization step were the two major parameters investigated in this study. With the aim to reduce the fractionating time, choices of solvents included xylene, xylene/ethylene glycol and xylene/glycerol. The cooling rate was varied from 1-10°C/h. The crystallized polymer fractions were subsequently eluted out of the column. Each of the eleven fractions was analyzed for short chain branching content by 13C-NMR performed at l30°C. The highest cooling rate for fraetionating C₄-LLDPE was found to be 5°C/h when xylene was used during crystallization. The cooling rate could be increased to 7°C/h when using 0.3% ethylene glycol/xylene while obtaining the same fractionating efficiency. For C6-LLDPE and C8-LLDPE, the highest cooling rate was found to be 2°C/h with xylene, but 2°C/h and 1°C/h with 0.3% ethylene glycol/xylene, respectively. When 0.1% glycerol in xylene was employed, the cooling rate could not be higher than 1°C/h for all three LLDPE samples. DSC was also used to determine the thermal characteristics of every fraction obtained from TREF using xylene in crystallization step.

title: Synthesis and characterization of superabsorbent poly[acrylamide-co-(itaconic acid)]/silica composites

description: A series of superabsorbent polymer synthesized by solution polymerization using a short polymerizing time of for acrylamide (AM) and itaconic acid (IA) monomer via a redox initiator system of 1.0 %wt ammonium persulfate and 0.20 cm³ of N,N,N’,N’-tetramethylethylenediamine, the crosslinking agent of 0.5 %wt N,N’-ethylenebisacrylaminde were carried out with a stirring speed of 250 rpm at the temperature 45◦C for 30min. Silica was used as an inorganic component in the polymerization process to strengthen the copolymer. The synthesized copolymers were dewatered and precipitated by excess methanol and drying at 50◦C in vacuum oven for 24 h. absorption and absorption kinetics behavior of the polymers were investigated. In addition, the water absorbency under load of the synthesized copolymer at 0.28 and 0.70 psi were investigate. The functional groups of copolymer were investigated by Fourier transform infrared spectroscopy, surface morphology by scanning electron microscopy, and thermal properties by differential scanning calorimetry The synthesized copolymer gave the highest water absorbency of 233±8 times its dry weight at the AM-toIA ratio of 97:3, amd could absorb up to 149±2 times its dry weight within 15 min. The highest absorbency under load of the copolymer was 13.2 and 12.1 times its dry weight with 2.0%wt silica at the load of 0.28 and 0.07 psi, respectively. Moreover, the surface morphologies of the copolymer were revealed by SEM technique, which indicated that the porous structure was found in the synthesized copolymer giving the high Tg, which indicated that silica has been incorporated in the copolymer.

title: Derivatives of functions on the sierpinski gasket

description: Let ƒ be a real-valued harmonic function on the Sierpinski gasket(SG) with bound-ary points p0,p1 and pg. We define three derivatives (three directions) at each junction point p in SG depending on its location. We will show that any harmonic function has finite derivatives at each junction point and obtain derivative formulas and some of their properties. Finally, we define another derivative on the set of junction points for which the first derivative coincides with the old definition for harmonic functions and the second derivative is zero at junction points.

title: Sorption and transport of polar organic compounds in groundwater

description: Currently, pharmaceutical compounds have been widely detected in surface waters and groundwaters, leading to increased interest in the transport of these compounds in the subsurface environment. In this study, the sorption of four pharmaceuticals with various characteristics (non-hydrophobic, hydrophobic, ionizable monoprotic, ionizable amphoteric); acetaminophen (analgesic), 17[alpha]-ethynyl estradiol (synthetic hormone), nalidixic acid (antibiotic) and norfloxacin (antibiotic), were evaluated with silica, alumina, and Porapak P (hydrophobic medium). The pH dependent sorption of nalidixic acid and norfloxacin to silica and alumina were studied at pH4 to pH9. The fundamental sorption characteristics were revealed from this study and were extended to sorption and column transport of these pharmaceuticals to natural aquifer media from shallow aquifer, in Central Thailand. The column breakthrough curves of 17[alpha]-ethynyl estradiol and nalidixic acid showed sorption-related nonequilibrium characteristics. The UFBTC, one dimensional finite different transport model was used to model the column experiment data. The comparisons of Retardation Factor from column transport studies and predicted from batch studies were presented. Finally, the subsurface sediments (clayey silts and sands) with varying surface property (i.e., AEC, CEC) and organic carbon contents from three boreholes in groundwater recharge area, Central Thailand were studied for sorption affinity and compared to the more common pollutant (i.e., pesticide mobility scale)

title: Supplementary Material for: Efficacy and Feasibility of Magnifying Blue Laser Imaging without Biopsy Confirmation for the Diagnosis of the Demarcation of Gastric Tumors: A Randomized Controlled Study

description: <b><i>Background:</i></b> Accurate diagnosis of the demarcation line (DL) of gastric tumors is essential for curative complete resection by endoscopic submucosal dissection (ESD). It is controversial to perform only magnifying endoscopy for diagnosing the DL of gastric tumors prior to ESD. This study aimed to evaluate the diagnostic accuracy for the DL of gastric adenomas and well-differentiated adenocarcinomas using only magnifying blue laser imaging (M-BLI) compared with that using both M-BLI and biopsy confirmation. <b><i>Methods:</i></b> In this prospective, single-center study, 96 well-differentiated adenocarcinomas and 32 gastric adenomas were enrolled between July 2015 and December 2016. A total of 122 lesions with a clear DL on M-BLI were randomly allocated to undergo M-BLI only (the M-BLI group) or M-BLI with biopsy confirmation (the M-BLI-BC group), performed as biopsies in 4 directions from noncancerous tissues ≈ 5 mm outside the lesion before ESD. The primary end point was to clarify the noninferiority of M-BLI without biopsy confirmation compared with that with biopsy confirmation, in terms of the diagnostic accuracy and complete resection. <b><i>Results:</i></b> There were no significant differences in sex, median age, color, circumference, macroscopic type, biopsy-based diagnosis, and <i>Helicobacter pylori</i> infection between the 2 groups. The diagnostic accuracy for the DL was 100 and 95.0% and the complete resection was 100 and 100% in the M-BLI and M-BLI-BC groups, respectively. <b><i>Conclusion:</i></b> The diagnostic ability of M-BLI is excellent in diagnosing the demarcation of gastric adenoma and well-differentiated adenocarcinoma. Biopsy confirmation is not needed for these lesions with a clear DL by M-BLI.

title: Supplementary Material for: In-Hospital Blood Pressure Variability: A Novel Prognostic Marker of Renal Function Decline and Cardiovascular Events in Patients with Coronary Artery Disease

description: <b><i>Introduction:</i></b> Several measures of blood pressure (BP) variability have been associated with kidney disease and cardiovascular events. Although BP is routinely measured during hospitalization in daily practice, the prognostic impact of in-hospital BP and its variability are uncertain. <b><i>Methods:</i></b> A total of 226 participants who underwent elective percutaneous coronary intervention (PCI) for stable coronary artery disease (CAD) were included. BP was measured by trained nurses during the 4-day hospitalization for PCI. BP variability was assessed by standard deviation (SD) and coefficient variation of systolic BP. Estimated glomerular filtration rate (eGFR) was calculated at baseline and follow-up (≥6 months). The cardiovascular end point was defined as a composite of cardiovascular death, acute coronary syndrome, stroke, heart failure hospitalization, and any coronary revascularization. <b><i>Results:</i></b> In-hospital BP was measured 9.5 ± 0.8 times. During a median follow-up period of 1.7 years, mean eGFR change was −1.7 mL/min/1.73 m<sup>2</sup> per year, and 35 (15.5%) participants met the cardiovascular end point. Mean systolic BP and SD were negatively correlated with eGFR change. In the receiver operating characteristic curve analysis, SD of systolic BP predicted the cardiovascular end point (AUC 0.63, best cutoff value 14.2 mm Hg, <i>p</i> = 0.003). Kaplan-Meier analysis demonstrated a significantly higher incidence of the cardiovascular end point in patients with SD of systolic BP ≥14.2 mm Hg compared to their counterpart (<i>p</i> = 0.003). A multivariable analysis showed SD of systolic BP as an independent predictor for the cardiovascular end point. When assessed with coefficient variation, BP variability was similarly related to eGFR change and clinical outcomes. <b><i>Conclusion:</i></b> Greater in-hospital BP variability was associated with renal function decline and cardiovascular events in patients with stable CAD.
