title: Sensors based on curcumin borondifluoride for naked-eye-detection of cyanide

description: Novel curcumin derivatives containing BF₂-incorporated curcumin, BF₂-CurOH, BF₂-CurOMe, BF₂-CurmonoTs and BF₂-CurdiTs have been synthesized. The photophysical properties of all BF₂-curcumin derivative revealed that electron donating modified on aromatic ring (BF₂-CurOMe) induced the bathochromic shift of the absorption and emission spectra. In contrast, the electron-withdrawing modified on aromatic ring resulted in the hypsochromic shift in both absorptions and emissions. The quantum yields of BF₂-CurOH, BF₂-CurOMe, BF₂-CurmonoTs and BF₂-CurdiTs in dichloromethane were 0.62, 0.61, 0.22 and 0.48, respectively. Interestingly, BF₂-incoorporated curcumin derivatives of BF₂-CurOH and BF₂-CurOMe exhibited solvent-dependent. The solvent dependent maximum absorption band of both compounds were analyzed using Kamlet-Taft relationship, the result showed that BF₂-CurOH and BF₂-CurOMe behaved the positive solvatochromism. Concerning on the anion sensing, BF₂-CurOH have excellent sensitivity and selectivity toward cyanide ion over curcumin. This phenomenon was subjected to deprotonation of hydroxyl group of BF₂-CurOH and curcumin. The negative charge on oxygen atom which can delocalize through π-conjugated bond. The deprotonation abilities by CN- to both compounds measured by UV-visible titration and fluorometric titration exhibited the log β values of 8.8 and 7.7 for BF₂-CurOH and curcumin, respectively. Interestingly, the effect of foreign anions toward cyanide detection for BF₂-CurOH was studied and showed that no effect on the determination of CN̄ except AcŌ, H₂PO₄̄ and F̄ while all anions have an effect for cyanide detection of curcumin in aqueous solution. Furthermore, the detection limit of CN̄ is 9.33 and 0.14 µM for curcumin and BF₂-CurOH, respectively

title: Dynamic behaviors of forest fire in upper Nan wastershed during 1999-2007

description: The applications of geographic information system (GIS) and remote sensing help gathering and analysis the spatial patterns of the forest fire more quickly and more efficiently. This research used the temporal Landsat-5 TM imageries covered the upper Nan watershed, Thailand, acquired between December to April during 1999-2007, to study the changes of the forest fire affected areas. In this study, Landsat-5 TM bands 7-4-2 were chosen to create the false color composite. The visual interpretation combined with Difference Normalized Burn Ratio (dNBR) method was conducted to analyze the forest fire affected areas that were created in GIS database. Field investigations were also used to test for accuracy of the forest fire interpretation. The results were used to produce the burned scar maps and synthesize for the trend of forest fire distribution during those periods. The analysis found that most forest fire patches distributed on high mountainous and steep slope area that are mainly in the northern part of the watershed. The forest fire areas in 1999, 2001, 2004 and 2007 were summarized approximately as 37 km2, 107 km2, 81 km2, and 80 km2, respectively. The relationships of burned areas and relevant parameters, namely slope, aspect, distance from road, distance from settlement, vegetation and land cover were analyzed for forest fire susceptibility assessment. Various maps were constructed from the forest fire relevant parameters derived from the database. The parameters, univariant probability method, and calculation of forest fire susceptibility were applied to modify the forest fire rating risk classes and be presented as the forest fire risk map in the upper Nan watershed. The final results from this research can be used as a spatial data for supporting decision making in handling, monitoring, and controlling the forest fires in Thailand for much better efficient management.

title: A study on climatic conditions, body temperature and cardiovascular response during outdoor exercise in physical education class in the schoolboys of Chulalongkorn University Demonstration Elementary School

description: This descriptive study aimed to determine climatic conditions, body temperature, cardiovascular responses, hydration status and the incidence of heat illness during outdoor exercise in physical education class in 457 schoolboys of Chulalongkorn University Demonstration Elementary School. The study was performed in the first (July-September) and second (November-February) semesters of the academic year 2009. Body weight, blood pressure, pulse rate and core body temperature were measured before and after outdoor exercise in physical education class. Physical education classes climatic conditions were measured every five minutes and video image of the events were recorded for evaluation of exercise duration and intensity as well as the incidence of heat illness. However, the subjects were allowed to drink water and urinate during their physical education classes. It was found that the characteristics of the schoolboys were as follows: age 8.38 ± 1.56 years, height 130.72 ± 10.45 cm, weight 30.81 ± 9.39 kg, BMI 17.68 ± 3.35 kg/sq.m and BSA 1.05 ± 0.19 sq.m. The climatic conditions included the ambient temperature 33.56 ± 2.55℃, relative humidity 54.15 ± 8.12% and Wet Bulb Globe Temperature (WBGT) 28.87 ± 2.35℃ (first semester 29.95 ± 1.87℃, second semester 28.32 ± 2.39℃). Total duration of physical education class was 31.97 ± 11.10 min. Outdoor physical activity consisted of skill practice (duration 24.11 ± 11.04 min, intensity &lt; 3 MET) and sport playing (duration 11.48 ± 5.53 min, intensity 2.5-9 MET). Before and after outdoor exercise, the percent change in systolic and diastolic blood pressure, mean arterial pressure and pulse rate was increased by 16.00, 21.59, 19.05 and 22.05%, respectively. Sweat rate was 391.16 ± 186.75 mL/hr. Core temperature was increased by 0.66 ± 0.41℃ from 36.48 ± 0.37℃ to 37.14 ± 0.42℃. There were 20 schoolboys (7 schoolboys in first semester, 13 schoolboys in second semester) whose core temperature reached up to 38℃; this accounts for 4.38% of all subjects. Among these, 18 schoolboys did not drink water and 2 schoolboys drank water of 158 and 340 mL while exercising in physical education class. However, no incidence of heat illness was found. In conclusion, there is a tendency for heat illness during outdoor activities in physical education class in primary school children. It is recommended that climatic conditions and children’s core temperature be measured before the start of physical education class. The children should be encouraged to drink enough water before and during exercise

title: Thai truck loading monitoring and assessment of existing concrete bridges

description: At the present decades, bridge assessment and evaluation are the vital issues in Thailand. Due to that many old bridge structures are inclined and deteriorated. In the contrast, the present truck loads are heavier than previous truck loads. To evaluate the old bridge structure, the actual truck data have to be available. Therefore, this study has mainly studied on development truck load monitoring system, and assessment for existing bridges. In Thailand, bridges have been designed by HS20-44 bridge design truck designed by AASHTO for many years, but the actual truck loads are greater than those the design truck. However, the data for local truck load has not been available to develop bridge truck load design for Thailand. Therefore, this study proposes an alternative truck load monitoring system based on the bridge weigh-in-motion (B-WIM) algorithm. The system is inexpensive, no devices exposed on the road, and it is convenient in installation and maintenance. From results of testing monitoring actual truck load, the system estimates the GVW of the truck within 6% to 10% error. Many constitutive models for nonlinear finite element method (NLFEM) for analysis concrete and reinforced concrete structures can not account for existing flaw/crack in old concrete and reinforced concrete (RC) members. In this study, the softening model for concrete and tension stiffening model for RC members are adopted to account for existing flaw/crack for analysis old concrete and RC structures. Some notched concrete and RC beams are analyzed to verify the proposed models which notch is assumed as an existing flaw. The analysis results of these examples are very close to the test results. To apply the proposed models which existing flaw/cracks are accounted, three concrete slab bridges have been analyzed by 3D NLFEM. The analysis results obtained from the proposed models have then compared to truck test results and to general NLFEM results. The results obtained from the proposed models are closed to the test results, while the results by general NLFEM are much less than those of the test results. After that, two concrete slab bridges are continued to analyze evolution their capacity using the proposed models and using maximum truck load from monitored data. From the analysis results, the behavior and capacity of the bridges can be obtained reasonably which bridge capacity obtained from the proposed models is less than those from general NLFEM and higher than those from simplify method of AASHTO

title: Synthesis of fatty acid amides, fatty acid esters and their derivatives using halogenating agents and triphenylphosphine

description: The methodology for the synthesis of fatty acid amides, fatty acid esters and their derivatives utilizing halogenating agents and PPh3 was developed. Trichloroacetamide coupled with PPh3 was found to be an effective system for this kind of conversion. To optimize the reaction conditions, type of halogenating agents and PPh3, reaction time and temperature were investigated. Polystyrene-supported PPh3 was used in this reaction to simplify the purification of the product. The optimum condition for the fatty acid chloride preparation step and the nucleophilic attack step were achieved when refluxed both steps in CH2Cl2 for 30 min each. The use of polystyrene-supported PPh3 also gave a comparable yield to that of PPh3. This methodology was applied to synthesize aromatic, short chain and long chain aliphatic fatty acid amides and esters. Furthermore, the developed methodology for the preparation of fatty acid derivatives including fatty acid thioesters and fatty acid anhydrides was successfully achieved.

title: Effect of processing conditions on properties of benzoxazine-urethane copolymers

description: The purpose of this research is to improve performance of polybenzoxazine by alloying with an excellent flexible urethane elastomer which can enhance the flexibility of polybenzoxazine. The polymer alloys of polybenzoxazine and polyurethane was prepared by processing conditions in two methods i.e. Traditional cure method by immediate using thermal treated and Sequential cure method by firstly, moisture in order to produce urethane network following thermal treated. The effects of processing methods were investigated in term of thermal and mechanical properties. In addition, to determine suitable alloy compositions between benzoxazine and urethane resins based on the above processing techniques. The experimental results revealed that the processing window of the BA-a/PU resin mixtures was widened with the amount of the urethane prepolymer. Especially, the synergistic behavior of glass transition temperatures (Tg) of BA-a/PU alloys under both processing conditions is clearly observed. Tg’s of the BA-a/PU alloys under both processing conditions were significantly greater than those of the neat resins, i.e. BA-a (Tg = 186oC) and PU (Tg = -61oC). Tg’s of the BA-a/PU alloys increase with the mass fraction of the PU. The highest value of glass transition temperature was 260 oC under sequential cure method and 252 oC under traditional cure method at BA-a/PU 60/40. Furthermore, the degradation temperature was also about the same up to the PU content of 40 % by weight. The highest value of initial decomposition temperature at 5% weight was 329 oC under sequential cure method and 348 oC under traditional cure method at BA-a/PU 60/40. Moreover, the char yield of the alloys under both processing condition was enhanced with increasing amount of the benzoxazine mass fraction. In addition, the incorporate of benzoxazine structure with polyurethane can reduce their swollen and broken network in chloroform. Finally, the processing conditions of BA-a/PU alloys have no significant effect on above properties. On the other hand, the composition of BA-a/PU in alloys should be considered as the mainly influence.

title: Electrochemical synthesis of 1,3-propanediol from crude glycerol from biodiesel production

description: This work was carried out to evaluate the optimum conditions for synthesis of 1,3-propanediol from crude glycerol by an electrochemical technique. The experiment of glycerol reforming was separated into three parts. The first part was studied the glycerol reforming from synthetic and purified crude glycerol to 1,3- propanediol by the electrochemical technique. It was found that the optimum conditions; applied current intensity of 4.5 A, an initial pH of 1 set by H2SO4, 2.93 g/l NaCl, electrical charge of 100 Ah/l with Pt electrode; provided the yield of 1,3- propanediol by using synthetic and crude glycerol of 40.81% and 4.76%, respectively. For the second part, the purification of crude glycerol from biodiesel plant under strong acid conditions by using the chemical process was observed. The pH of crude glycerol was adjusted to 2.2 by 1.19 M H3PO4 and extracted glycerolrich layer solution with n-C6H14. After that, glycerol-rich layer neutralized with 12.50 M KOH and extracted with excess C2H5OH could provide the purity of glycerol around 97.92 % with low contaminant levels ash, matter organic non glycerol and water around 0.01, 0.79 and 1.28% w/w, respectively. As studied in the final part of the purified crude glycerol reforming to 1,3-propanediol, the optimum conditions of applied current intensity of 6 A, an initial pH of 1, and an electrical charge of 184.61 Ah/l with Pt electrode could provide the yield of 1,3-propanediol about 26.31%.

title: The influence of postprandial hypertriacylglycerolemic state of type 2 diabetes with varied insulin resistance on alterations of apoproteins in triacylglycerol-rich lipoproteins study using mass spectrometry

description: It is known that insulin resistance plays role in diabetic dyslipidemia especially hypertriacylglycerolemia (HTAG). However, in good metabolic controlled type2 diabetes mellitus who have normal fasting triacylglycerol level, the HTAG can observed only in postprandial state. In this research, the influence of insulin resistance on lipoprotein profiling and apoprotein of triacylglycerol-rich lipoprotein especially very low-density liprotein (VLDL) were studied. Eleven type2 diabetic subjects with moderated metabolic control (HbA1c &lt;8%), were classified as lower insulin resistance, LIR (HOMA-IR&lt;2.5), n=5 and higher insulin resistance, HIR (HOMA-IR 2.5-5.0), n=6 comparable to 10 nondiabetic controls. After at least 12 hours of fasting, subjects consumed a fat-rich meal. Before and the 4 hours after the meal, blood samples were taken for determination of glucose, insulin, lipids and lipoproteins in Experiment I. The increasing of postprandial triacylglycerol was found in chylomicron VLDL and HDL fractions especially in HIR group. For Experiment II, VLDL was isolated using sequential ultracentrifugation, delipidated and separated with 2D-PAGE and identified using ESI-IT, LC-MS/MS and MALDI-TOF MS. In total 26 protein spots representing 14 proteins including novel protein, transthyretin (TTR) with their isoforms were identified in VLDL. The comparisons of 14 proteins were analyzed in 6 pooled VLDL between fasting state and postprandial state within the same group as well as among different groups. The significant alterations compared between fasting and postprandial state of VLDL proteins (p&lt;0.05) in all groups were observed among apoC-II, apoC-III, apoE, apoA-I, except for TTR which was found only in HIR one. In fasting state, the significant changes of apoA-I, apoA-IV, and apoC-II were observed in LIR and HIR, whereas of apoC-III, apoE and TTR were observed in HIR in comparison to controls. In addition, significant modifications were found in apoA-I, apoC-II, apoC-III, apoE, and TTR of postprandial state compared to controls. These findings illustrate that insulin resistance is not only associated with increased VLDL triacylglycerol levels but also with alterations in VLDL protein composition which possibly affect the lipoprotein metabolism in diabetic patients.

title: Kinetic theory based computation of hydrodynamics and mass transfer in fluidized beds

description: The fluidized bed systems were modeled using computational fluid dynamics simulation with kinetic theory of granular flow. The proposed numerical models give better result than the previous published models. The models thus are suitable for providing more information about particle cluster and other in-depth parameters those described the hydrodynamics and mass transfer. This knowledge will lead to efficient system design. The computed particle cluster diameters using kinetic theory of granular flow method and particle cluster concentrations using statistical method agree with the published empirical correlations. The models were accurately used to calculate the granular temperatures and the dispersion coefficients. Then, the mass transfer coefficients and the Sherwood numbers were estimated based on particle cluster diameters and were computed using the concept of additive resistances with chemical reaction. The novel system geometry designs were also studied. These results provide the criteria for choosing system geometry with different reaction characteristics. The tapered-out and tapered-in risers will suit for the reactions with fast and slow rates, respectively. Besides, some in-depth hydrodynamics parameters were obtained from real experiment in the fluidized bed system.

title: Bulk optode sensors for detection of lead ion

description: A sensitive optode membrane based on highly lead-selective ionophore, chromoionophore (ETH 5294) and cation exchanger (KTpClPB) in plasticized PVC was fabricated. The optode membranes were used for determination of Pb[superscript 2+] by absorption spectrophotometry in batch and flow-through systems.The influence parameters such as pH solution,type of buffer, concentration of conditioning and regenerating solutions, time of condition and regeneration, and response time were studied. This sensor responded to Pb[superscript 2+] by changing color from blue to pink purple in TRIS buffer containing different concentrations of Pb[superscript 2+] at pH 7.0. The optode provided the response range of 3.16×10[superscript -8] to 5.00×10[superscript -5] mol L[superscript -1] Pb[superscript 2+] with detection limit of 2.49×10[superscript -8] mol L-1 in batch system within the response time of 30 min. The dynamic range of 1.26×10[superscript -8] to 3.16×10[superscript -5] mol L[superscript -1] Pb[superscript 2+] with detection limit of 8.97×10[superscript -9] mol L-1 were obtained in flow-through system within the response of 15 min. Moreover, the proposed optode membrane showed good selectivity toward Pb2+ over Na+, K+, Mg2+, Cd2+, Hg2+ and Ag+. It was successfully applied to determine Pb2+ in real water samples and the results were compared with inductively coupled plasma optical emission spectrometry (ICPOES). No significant different value was found between both methods at 95% of confidence level.
