title: Raw Twitter Datasets Based on Depressive Words

description: Right now we see that depression is one of the most common problems in our society. Most of the time people are committedsuicide only cause of depression. And till now there is no proper lab test way for detecting depression. Generally, doctors are detecting depression by asking some knowledgebase questions.On the other hand, there are a good number of people using social media platforms right now, where they are sharing their daily experiences, emotion, and other activity with their friends. Twitter is one of the common social platforms and also popular for data collection. I was collecting this data from twitter based on some depressive words.I hope that this data will help researchers to detect depression more precisely.

title: Parkes observations for project P1041 semester 2020APRS_13

description: We recently discovered five millisecond pulsars (MSPs) in the globular cluster Omega Centauri. This is the first pulsar discovery in this globular cluster. Four of these pulsars are isolated with spin periods of 4.1, 4.2, 4.6 and 6.8ms. The fifth has a spin period of 4.8ms and is in an eclipsing binary system with an orbital period of 2.1 hours. We propose to carry out a timing campaign of these new pulsars in order to study the dynamics in the core of Omega Centauri, to reveal the origin of Gamma-ray emission from the core, and to probe the ionised interstellar medium in Omega Centauri. Our proposed observations will also enable us to carry out deeper searches of pulsars in the cluster.

title: Synthesis of diethanolamide from palm kernel oil using cadida antractica lipase

description: Synthesis of diethanolamide using transamidation reaction from crude palm kernel oil (PKO) and diethanolamine (DEA) is investigation in this study. The catalysts used are sodium methoxide at a concentration of 1% and lipase from cadida antractica at a concentration of 1%. The reaction was carried out in a batch reactor at temperatures of 60, 80 and 120 ℃, pressure of 5 bars, molar ratios (DEA: PKO) of 3:1, 6:1 and 15:1 and reaction times from 2 to 8 hours using sodium methoxide as catalyst. Temperatures of 40, 50 and 60 ℃ and reaction times from 6 to 24 hours were used with lipase. The results show that the optimum conditions when sodium methoxide was used as catalyst were a temperature of 60 ℃, a molar ratio of DEA to PKO of 6:1 and reaction time of 4 hours. Diethanolamide concentration of 93.24% was obtained at this condition. When lipase was used as catalyst, the optimum conditions were a temperature of 60 ℃ and a molar ratio of DEA to PKO of 3:1 for 24 hours. Diethanolamide concentration in reaction product of 10.20% was obtained. The second order kinetic was found to give suitable description of this reaction rate for both catalysts, and the rate constants of PKO were estimated to be 1.11 and 1.00 l/mol hr.g-cat, respectively. It is concluded that the rate reaction using sodium methoxide as catalyst is facter than using lipase as catalyst.

title: Correlation between Amikacin and Ceftazidime pharmacoknetic parameters

description: Aim: Ceftazidime and amikacin are usually prescribed together for the treatment of suspected or documented gram-negative bacilli infection. Similar physicochemical properties of ceftazidime and amikacin may contribute to good relationship of their pharmacokinetic parameters. This study was conducted to prove this hypothesis and create predictive pharmacokinetic parameter equations for each other. Method: Prospective observative pharmacokinetic study was performed in nineteen patients who received ceftazidime and amikacin as part of therapy at Phramongkutklao Hospital. Two plasma concentrations at steady state of both antibiotics were used for calculating the pharmacokinetic parameters. Regression analysis were performed to determine a correlation and predictive equation between ceftazidime and amikacin pharmacokinetic parameters. Results: Regression analysis showed a significant linear with high correlation between total drug clearance (Cl), elimination rate constant (K[subscript e]) and elimination half life (t[subscript 1/2]) of ceftazidime and amikacin (r = 0.966, 0.942, 0.891 for Cl, K[subscript e] and t[subscript 1/2], respectively). The correlation between clearance of amikacin and ceftazidime was better than the correlation between either drug clearance and creatinine clearance. A fair correlation was found between the volume of distribution (L/kg) of the two drugs (r = 0.671). Conclusion: A high correlation between pharmacokinetic parameters of ceftazidime and amikacin in this study indicated that ceftazidime pharmacokinetic parameters could be accurately predicted from those of amikacin and vice versa. This will help in modification of drug dosage regimen for individual patient in order to maximize therapeutic effect and minimize antimicrobial-resistant bacteria.

title: Efficacy of polyethylene plastic wrap for the prevention of hypothermia during immediate postnatal period in premature infants : a randomized controlled trial

description: Objective: To assess the efficacy of occlusive body wrapping with polyethylene plastic bag to prevent hypothermia in premature infants during immediate postnatal period. Design: Randomized controlled trial Setting: King Chulalongkorn Memorial Hospital, Thai Red Cross Society Methods: Premature infant of 34 weeks gestation or less were randomized to study or control group. Study infants were placed in polyethylene plastic bags immediately after birth in delivery room, leaving only the head uncovered and were kept in plastic bags for 3 hours. Any resuscitation or treatment was done with the bags covering the bodies. Control infants were dried and resuscitated per standard protocol before transferred to nursery. All infants were stabilized under radiant warmers. Rectal temperature was taken on nursery admission and hourly thereafter for 3 hours by a digital thermometer. Results: Of 130 randomized infants, 122 completed the study (61 in each group). The infants in wrap group had lower incidence of hypothermia on admission (26.2 vs 50%, p=0.007, OR 0.36; 95%CI, 0.17 to 0.76) as well as hypothermia during the 3 hours study period (44.3 vs 70.5%, p=0.003; OR 0.33, 95%CI, 0.16 to 0.70). Wrapped infants also had higher rectal temperature on admission (36.7 ± 0.54 vs 36.3 ± 0.66 ºC, p= 0.002) and at 1 hour after admission (36.6 ± 0.46 vs 36.4 ± 0.46 ºC, p= 0.032). The effects of wrapping on prevention of hypothermia was still significant after adjustment for birth weight, small for date, low 1-minute Apgar score, and umbilical catheterization (adjusted OR 0.39, 95%CI, 0.17 to 0.87). Subgroup analysis showed significant higher admission rectal temperature and lower incidence of hypothermia on admission and throughout the study period in infants of less than 31 weeks’ gestation (difference in mean rectal temperature = 0.62 ºC, 95% CI, 0.18 to 1.05) but not in infants of 31 to 34 weeks’ gestation. Conclusion: Occlusive body wrapping with polyethylene plastic bag in delivery room is efficacious in the prevention of hypothermia in premature infants during immediate postnatal period.

title: Effects of piperine on hydrogen peroxide-induced cell death in neuronal cell line cultures

description: Piperine has been widely used in folklore medicine to treat a variety of central nervous system disorders and has marked antioxidant property which may suggest its potential to alleviate oxidative stress-induced neurodegenerative process. The primary objectives of this study were to study beneficial effects of piperine on hydrogen peroxide (H O )-induced cell death in neuronal cell line cultures and investigate possible mechanisms underlying its neuroprotective effects. A cellular model of neurodegeneration induced by H O in N1E-115 cell line cultures was used to investigate the oxidative stress-induced neuronal cell death in this study. MTT reduction and LDH release assays were used to analyze cell survival and death. Lipid peroxidation, cellular GSH contents, and apoptotic cell death were used to analyze possible mechanisms of neuroprotection. Experimental results from this study suggest that piperine possessed bimodal effects on neuronal cell cultures, cytoprotective at lower concentrations and cytotoxic at higher concentrations. Simultaneous exposure with nontoxic concentrations for piperine, in a range of 0.1-10 N, amy be protective against cell injury and apoptotic cell death from exposure to H O in N1E-115 cell line cultures. However, pre[exposure to piperine did not show any beneficial effects. The mechanism of action underlying this beneficial effect of piperine on cultured neurons is unclear at the present time. Possibly, it may involve differen6 direct and indirect actions of piperine, e.g., antioxidation and free radical scavenging, interference with Fenton’s reaction which generates TROS, inhibition of cellular lipid peroxidation, counteraction to ap0optotic cell death cascade. Further studies for clarifying detailed pharmacological properties and potential applications of piperine in experimental research are warranted.

title: Molluscicidal constituents from Trichosanthes Cucumerina fruits on Pomacea Canaliculata

description: The chemical study of the fruits of Trichosanthes cucumerina L. (Buap khom) led to the isolation of a triterpenoid saponin. The structure determination of this compound was accomplished by spectroscopic analyses (UV, IR, MS and NMR) and by comparison with previously reported data of the known compound cucurbitacin B, C[subscript 32]H[subscript 46]O[subscript 8], 25-acetoxy-2B, 16a,20B-trihydroxy-9B-methyl-19-nor-10a-lanosta-5,23-diene-3,11,12-trione. Cucurbitacin B showed molluscicidal activity against Pomacea canaliculata Lamarck (2.0-2.5 cm, in diameter) with LC[subscript 50] value of 9.02 ppm and LC[subscript 90] value of 17.67 ppm after 24 h at 95% confidence interval. Assays by MTT [3-(4,5-dimethyl thiazol-2-yl)-2,5-diphenyl tetrazolium bromide] colorimetric method with 5 cancer cell lines including human colon adenocarcinoma (SW620), human liver hepatoblastoma (HEP-G2), human gastric carcinoma (KATO-III), human breast ductal carcinoma (BT474) and human undifferentiated lung carcinoma (CHAGO) revealed that cucurbitacin B has strong cytotoxic activity against human colon adenocarcinoma (SW620) and human liver carcinoma (HEP-G2) with IC[subscript 50] values of 0.06 and 0.09 ug/mL, respectively. It appears that T. cucumerina L. (Buap khom) has potential to be used as a molluscicide substitute for toxic chemicals.

title: Identification and differentiation of Mycobacterium tuberculosis complex organisms in bovine clinical samples by Polymerase chain reaction

description: Mycobacterium bovis and Mycobacterium tuberculosis are the public health important bacteria that cause diseases in both animals and humans, especially in cattle and dairy farm workers. In this study, 36 tissue samples were collected from 24 dairy cows previously diagnosed as tuberculin positive in Nakhon Pathom province, Thailand. Infection with Mycobacterium organisms was confirmed by histopathologic examination and AFB staining. Species identification was made by using a panel of PCR based on 3 specific genes (16SrRNA, Rv1970, JB fragment) and direct sequencing using oxyR gene. Thirty of 36 (83.33%) clinical tissue samples were identified as Mycobacterium spp., 12 from 30 (40%) were positive for M. tuberculosis while 18 from 30 (60%) were positive for M. bovis strains. DNA fingerprints using variable number tandem repeat (VNTR) was used to differentiate among M. bovis and M. tuberculosis isolates. Eighteen of M. Bovis isolates can be grouped into 6 VNTR patterns. However, VNTR analysis indicated that 12 of M. tuberculosis isolates infected in cattle were identified in only one VNTR pattern. Our result showed that the combination of PCR and gene sequencing are very useful for identification of M. bovis and M. tuberculosis from clinical tissue samples. Moreover, VNTR is a simple useful tool for strain differentiation and for the study of genetic diversity, especially for M. bovis.

title: Soft sensor for quality estimation of product in cyclohexanone unit

description: Accurate measurement of quality variables are importance for the complete quality monitoring and control tasks in chemical process. Unfortunately, few analysers or hardware sensors for measuring the key variables are available and difficult to maintain. Moreover, these have also limitations such as very high cost and the large time delays. Therefore, it is necessary to utilize soft sensors to estimate the quality variables using other directly measurable secondary variables. In this work, three estimating approaches by using empirical models being multilayer feedforward (MLFF) artificial neural networks (ANNs), partial least squares (PLS) regression, and neural network partial least squares (NNPLS) are exploited to build soft sensors able to estimate the top product of the distillation column in the cyclohexanone unit using available temperature measurements in the column. However, buildings of soft sensor models using only real plant data have the hard limitation since they cannot implement in wide range estimation because of the plant data having smooth responses or small data variations. In order to handle this problem, this work used two data sources which were real plant data and wide range simulated data for constructing the soft sensors. These two data sources were mixed together to calculate parameters of the soft sensor model based on PLS model. For MLEF and NNPLS model, the wide range simulated data were used to pre-train or pre-calibrate parameters of soft sensor models and used the real plant data for find-tuning the parameters again. In case study, the results proved that all of the soft sensors showed satisfactory estimating performances and soft sensor based on MLFF method gave better estimating performances than both of the PLS methods.

title: Preparation of Cu/ZnO and Cu/TiO[subscript 2] catalysts via deposition technique using critical carbon dioxide

description: A novel method for preparation of Cu/ZnO and Cu/TiO² catalysts using supercritical carbon dioxide was investigated. Supercritical carbon dioxide was employed as a solvent to dissolve the copper compound. The dissolved compound was then used to deposit the metal on ZnO and TiO² support. Both ZnO and TiO² supports were synthesized by a solvothermal method using 1,4-butanediol as a solvent. The catalysts were characterized by various techniques, including X-ray diffractometer, nitrogen physisorption, inductively-coupled plasma atomic emission spectroscopy, and chemisorption. Cu/ZnO and Cu/TiO² were then employed as catalysts for oxidation of CO. Both Cu/ZnO and Cu/TiO² catalysts that were prepared by deposition technique using supercritical carbon dioxide and methanol exhibited higher activities for oxidation of CO than the catalysts that were prepared by incipient wetness impregnation technique. This could be attributed to higher dispersion of copper on the supports brought about by the use of supercritical carbon dioxide. Cu/ZnO and Cu/TiO² catalysts that were prepared by deposition technique using supercritical carbon dioxide and a sulfer-contaning compound, Cyanex 301, exhibited very low activities for oxidation of CO due to poisoning of the catalysts caused by remaining organics on the surface of the catalysts.

title: Effect of surface defect of titanium dioxide on photocatalytic activity for water decomposition to hydrogen

description: Effects of TiO₂ surface defects on photocatalytic activity for water decomposition to hydrogen are also investigated. Nanocrystalline titanium dioxide was prepared using the solvothermal method. Obtained titanium dioxide powder was treated to modify the surface properties by quenching in various media. For quenching in liquid phase medias, water at room temperature and 373 K, hydrogen peroxide at room temperature and 373 K were selected. For quenching in gas phase media, air at room temperature, 373 K and 77 K were selected. It is also found that quenching titanium dioxide catalysts in various media is not significantly differences in the crystallites size and BET surface area, but it is also found that quenching immediately after calcined was increasing amount of Ti³⁺ on surface of catalyst and exhibited increasing photocatalytic activity. Quenching in a similar medium, TiO₂ quenched in cooler media exhibited higher photocatalytic activity than those quenched in hotter ones. For room temperature quenching, the photocatalytic activities of TiO₂ quenched in air exhibited higher activity than those quenched in 30 %wt H₂O₂ and H₂O, respectively. There were observed that start of the reaction because of bridging hydroxyl group and water on the TiO₂ surface.
