Incorporation of a Pd catalyst at the fuel electrode of a thin-film-based solid oxide cell by multi-layer deposition and its impact on low-temperature co-electrolysis

To enhance the electrochemical performance and syngas production in low-temperature co-electrolysis (LT-Co-EC), incorporation of Pd into the nickel–yttria-stabilized zirconia (Ni–YSZ) fuel electrode functional layer (FEFL) of a thin film-based solid oxide cell (TF-SOC) by multi-layer thin film deposition was investigated. The optimal configuration to insert a Pd layer without disturbing the surface and cross-sectional microstructure of the FEFL was fabricated by alternating multi-layer deposition of Pd by sputtering and nickel oxide–yttria-stabilized zirconia (NiO–YSZ) by pulsed laser deposition (PLD). TF-SOCs with Pd (Pd-cell) and without Pd (Ref-cell) were fabricated and compared based on the electrochemical reaction and syngas production in LT-Co-EC. The results showed that the catalytic activity by forming the Pd–Ni alloy on the electrochemical performance and thermochemical reaction are improved by Pd incorporation at low temperatures (≤600 °C). Detailed microstructural analyses showed that Pd distributes from the electrode/electrolyte interface to a depth of several tens of microns in the anode support and forms a nano-structured Ni–Pd alloy, which contributes to improving the electrochemical reaction and thermochemical reactions such as water–gas-shift (WGS). It was also found that the performance stability was superior in the Pd-cell because pore array generation at the electrolyte/electrode interface was significantly suppressed in comparison with that of the Ref-cell.
Dental caries vaccine: An overview

Dental caries is an irreversible microbial disease of the tooth which fulfills the idea of an infectious disease and hence the possibilities of vaccination have been considered. Many pertinent components of vaccine development, such as protein, recombinant or synthetic peptide, or DNA-based active vaccines, as well as mucosal adjuvants, such as heat-labile enterotoxins from Vibrio cholera or Escherichia coli, and chitosan, have proven effective through numerous in vitro and in vivo researches, as well as some human clinical trials. The use of adjuvants and the routes of antigen administration have both been studied to improve the host response. Vaccines such as pGJA-P/VAX, LT derivative/Pi39-512, KFD2-rPAc and SBR/GBR-CMV-nirB are few of the potential vaccines that have been produced and tested in animals in recent years. However, there is still a scarcity of information about the role of caries vaccine in human population. Multicentre collaborative studies and clinical trials of immunologically superior dental caries vaccine formulations are the need of the hour for preventing dental caries.
Design and Implementation of Reinforcement Learning Agent Using PPO Algorithim for Match 3 Gameplay

Most of the match-3 puzzle games supports automatic play using the MCTS algorithm. However, implementing reinforcement learning agents is not an easy job because it requires both the knowledge of machine learning and the way of complex interactions within the development environment. This study proposes a method in which we can easily design reinforcement learning agents and implement game play agents by applying PPO(Proximal Policy Optimization) algorithms. And we could identify the performance was increased about 44% than the conventional method. The tools we used are the Unity 3D game engine and Unity ML SDK. The experimental result shows that agents became to learn game rules and make better strategic decisions as experiments go on. On average, the puzzle gameplay agents implemented in this study played puzzle games better than normal people. It is expected that the designed agent could be used to speed up the game level design process.
Bulk plasmon-phonon polaritons in n-GaN

We studied theoretically and experimentally plasmon-phonon polaritons and longitudinal plasmon-phonon oscillations in n-GaN epitaxial layers. The studies were carried out on the epitaxial layers with various doping levels. Simulation of the reflectivity spectra and dispersion relations of plasmon-phonon polaritons was performed in a wide frequency range. Reflectivity spectra transformation associated with phonon damping and electron relaxation processes has been revealed. Experimental studies of the reflectivity spectra have been performed in the spectral range of 8–80 meV. The experimental spectra are well fitted by the simulated ones. Results of the study can be used for contactless determination of the electron concentration and mobility in GaN epitaxal layers.
Release characteristics of polyphenols from microencapsulated Terminalia arjuna extract: Effects of simulated gastric fluid

ABSTRACT Terminalia arjuna (TA) encapsulated microcapsules were prepared using two different wall materials consisting of a combination of maltodextrin + gelatine (MDG) and maltodextrin + gum acacia (MDGA). Total phenolic, tannin, and flavonoids content of TA ethanolic extract were found to be 19.6 ± 0.7 g/100 g extract, 7.5 ± 0.7 g/100 g extract, and 2.7 ± 0.2 g/100 g extract, respectively. In vitro release of polyphenols increased with the time of stirring in simulated intestinal fluid (SIF; pH 6.8). The encapsulation efficiency (EE) and release of polyphenols (after 60 min) were observed to be 42 ± 4.g/100 g; 77.0 g/100 g; and 31.0 ± 0.5 g/100 g; 72.0 g/100 g, respectively for MDGA and MDG microcapsules. This study concluded that MDGA provided higher EE and stability than MDG for TA extract.
Influence des ratios de co-expression précis Cx43 : Cx45 sur la formation des canaux de jonction et leurs propriétés électriques

Les canaux de jonctions (CJ) composes des connexines (Cxs) assurent la communication intercellulaire directe qui par leur proprietes electriques regulent la propagation du potentiel d’action (PA) cardiaque. Dans les myocytes ventriculaires Cx43 et Cx45 exprimees a des niveaux et ratios physiopathologiques variables assurent cette fonction. Cette etude determine la contribution de Cx43 et Cx45 dans la formation des CJ et leurs proprietes electriques. La lignee cellulaire epitheliale de foie de rat exprimant la Cx43 endogene et transfectee de maniere stable pour exprimer des ratios Cx43:Cx45 precis a ete utilisee. Les proprietes electriques des CJ ont ete obtenues par double voltage clamp sur paires de cellules. L’expression de la Cx45 diminue le couplage electrique et augmente la dependance au potentiel de jonction independamment du ratio. Les cinetiques de desactivation sont ralenties avec l’augmentation du niveau d’expression de Cx45 et les cinetiques de restitution sont modifiees en fonction du ratio. Les conductances unitaires suggerent la formation de CJ composes de Cx43 et Cx45. La diminution du niveau d’expression de Cx43 par ARNi anti-Cx43 entraine une diminution du couplage electrique tandis que les autres proprietes electriques restent inchangees. Ces resultats montrent une contribution specifique de Cx43 et Cx45 dans la regulation de la formation et des proprietes electriques des CJ caracterisees. Ces proprietes seront correlees a la participation des CJ dans la regulation de la propagation du PA en fonction des profils d’expression des Cxs en conditions physiologiques et pathologiques.
Comparison of microwave-assisted hydrodistillation and solvent-less microwave extraction of essential oil from dry and fresh Citruslimon (Eureka variety) peel

Abstract This study investigated the effectiveness of microwave-assisted hydrodistillation (MAHD) and solvent-less microwave extraction (SLME) for extracting essential oil (EO) from lemon peels in comparison with conventional hydrodistillation (HD) in terms of extraction time, extraction yield, physical properties, chemical composition, operation cost, and antioxidant activity. The results showed that MAHD and SLME methods required an extraction time of 15 minutes while the required extraction time in HD was 120 minutes. There were no significant differences among physical properties (refractive index, specific gravity, and color) of extracted EOs by the three methods. Gas chromatography analysis did not indicate any noticeable change in the composition of EOs extracted by microwave-assisted extraction methods (MAHD and SLME) and HD method. DPPHº analysis of the extracted EOs indicated that microwave irradiation did not adversely influence antioxidant activity of the extracted EOs. The results of this study introduced MAHD and SLME as rapid, economical, and environmentally friendly extraction methods.
Exploring Hotel Customers’ Green Decision-Making Processes

This study examined hotel customers’ eco-friendly decision-making processes. Specifically, the current study tested the relationships among attitude toward green behaviors (ATGB), overall image (OI), visit intention (VI), word-ofmouth intention (WOMI), and willingness to pay more (WPM) by considering the effects of gender and age in a green hotel context. The results of structural equation analyses showed that OI is a positive function of ATGB and that OI significantly affects VI, WOMI, and WPM. Additionally, the findings from a structural modeling comparison revealed that OI completely mediates the effect of ATGB on components of behavioral intentions. Subsequent tests for metric invariance demonstrated that the relationships among study variables were generally stronger among females and high age groups. However, only the paths from OI to VI, WOMI, and WPM in the gender group and from OI to WPM in the age group were statistically significant. Implications and future research issues were discussed.
A Tightly-Coupled Visual-Inertial System with Synchronized Time for Indoor Localization

Indoor localization remains a difficlut problem due to the lack of global positioning facilities. In this paper, we present an indoor localization system based on tightly coupling the stereo camera and the inertial measurement unit (IMU). To achieve the correct fusion, we strictly synchronized the sensors by compensating for all of system delays, including the varied exposure time of camera. The calibration datasets were carefully recorded to obtain the exact model of the stereo camera as well as the relationship between the camera and the IMU. After preparing, we performed the localization by utilizing the keyframe-based visual-inertial odometry. This algorithm works by minimizing the IMU error jointly with the camera reprojection, to get an optimal estimation of robot states. The visual landmarks are calculated by keypoint matching and triangulation between current frames and keyframes. The keyframes are selected to view keypoints from different angles to improve the depth uncertainty of landmarks. The algorithm was put into practice by an embedded computer which has enough processing ability, while presented in a small size for convenient deployment on mobile robots. The experimental results indicated that the developed system could achieve sufficient accuracy and robustness under real-
Cdse/Zns Capped Thiolate for Application in Glucose Sensing

A semiconducting water soluble core-shell quantum dot (QD) capped with thiolated ligand is used in this study for application in glucose sensing. These QDs were prepared in house based on hot injection technique. The ZnS shell at the outer surface of CdSe core QDs is made via specific process namely, SILAR (successive ionic layer adsorption and reaction). The distribution, morphology and optical characteristics of prepared core shell QDs have been assessed by transmission electron microscopy (TEM) and spectrofluorescence, respectively. The results show that the mean particle size of prepared QDs is in the range of 10-12 nm and the optimum emission condition was displayed at 620nm. The prepared CdSe/ZnS core shell QDs were modified by utilizing six organic ligands L-cysteine, L-histidine, thio-glycolic acid (TGA), mercapto-propionic acid (MPA), mercapto-succinic acid (MSA) and mercapto-undecanoic acid (MUA) at room temperature through a ligand-exchange procedure. This ligand exchange process was chosen in order to produce a very dense water solubilizing agent the QDs surrounding surface. The result shows that CdSe/ZnS capped with thioglycolic acid (CdSe/ZnS-TGA) exhibit the strongest fluorescence emission; therefore it was used in advanced sensing application for the detection of glucose. The highly active CdSe/ZnS-TGA was then interacted with Glucose Oxidase enzyme (GOx) and horseradish peroxidase enzyme (HRP). In this study, determination of glucose level is depending on the QDs fluorescence intensity quenching effect, which is correlated to reaction of the conjugated enzyme-QDs. In the presence of 0.1 mM glucose, fluorescence intensity of the bioconjugate QDs was quenched about 12, 000 a.u. This bioconjugated GOX/HRP/QDs-capped TGA was further analyzed with known concentrations of glucose. Quenched fluorescence intensity was proportionate with glucose concentration. The resultant GOX/HRP/QDs-capped TGA system can be a suitable platform for glucose determination in real samples.
Terahertz and Microwave Spectroscopy of Liquids and Hydrogen-Bonded Clusters

The microwave (MW, 0.3-100 GHz) and terahertz (THz, 0.1-10 THz) regions of the electromagnetic spectrum are replete with a rich set of molecular motions, including soft inter- and intramolecular vibrations, torsions, and rotations. At room temperature these motions are well populated, and play an active role in condensed-phase chemistry on Earth. This work details the development of one MW and two THz spectrometers along with their application to the study of liquids and hydrogen-bonded clusters. In the first section, we cover the design and construction of a chirped pulse Fourier transform microwave (CP-FTMW) spectrometer. The instrument relies on a compact, inexpensive direct digital synthesis board to generate 2 GHz, 1 microsecond chirped pulses that, after amplification, polarize the rotational states of gas-phase molecules in a pulsed supersonic jet. In an initial demonstration, the CP-FTMW instrument is used to collect the 8-18 GHz rotational spectra of the ethanol-water and ethanol-methanol dimers. These data reveal evidence of quantum tunneling, and a complicated interplay between weak and strong hydrogen-bonds in both dimers. Next, we describe the ongoing development of a decade spanning high precision THz frequency comb, using THz time-domain spectroscopy. The instrument is capable of generating ~28000 comb teeth from 0.15-2.4 THz with a fractional precision of 1.8x10-9 and a Doppler-limited accuracy of 6.1x10-8. Further prospects for studies of intermolecular interactions in jet-cooled molecular clusters are also discussed. In the last section, we move to condensed-phase studies of THz orientational and vibrational motions of liquids. The liquids are excited with one or two intense time-delayed ultrafast THz pulses and probed with a non-resonant 40 fs Raman pulse. Initially, we use this approach to measure the picosecond molecular orientational alignment and decay timescales in several aromatic liquids. By adding a second THz pulse to the experiment and adjusting the delays between the three pulses, we control the orientational alignment of the molecules, and acquire phase-coherent 2D-THz-THz-Raman spectra in the time domain. The 2D responses of liquid CHBr3, CCl4, and CCl2Br2 show off-diagonal peaks from coupling between thermally-populated vibrational modes. In an extended bandwidth measurement, we observe photon-echo signals from liquid CHBr3 and a complicated pattern of dipole forbidden transitions. The molecular origins of the forbidden transitions are still under investigation, but are likely due to nonlinearities in the condensed-phase dipole moment surface. Coherence transfer, vibrational anharmonicity, and intermolecular coupling are also considered in this analysis.
Pairwise comparison using a Bayesian selection algorithm: Efficient holistic measurement

The method of pairwise comparison has been used in a wide range of contexts. In educational measurement, many pairwise comparisons are required for reliable measurement when the comparisons to be performed are selected using the commonly-used semi-random selection algorithm (SSA). We proposed a Bayesian selection algorithm (BSA) to obtain smaller standard errors of parameter estimates and higher reliability compared with the SSA, and we evaluated the performance of these algorithms in a simulation study. We conclude that 1) the BSA should be preferred to the SSA, 2) the number of comparisons required for reliable measurement depends on the object variance, and 3) the Scale Separation Reliability (SSR) may systematically overestimate reliability even when the SSA is used.

Diclofenac sodium is one of analgesic which added to herbal medicines to enhance the effects. One of a qualitative method that is easy, efficient and simple is an indicator strip test. Indicator strip based polystyrene (PS) and polymethylmethacrylate (PMMA) was made to detect of diclofenac sodium which misused in traditional pain relief herbal medicine. Indicator strip was made by reagent blending method with specific reagents, copper sulfate (CuSO 4 ), ferric chloride (FeCl 3 ) and vanillin sulfate. The principle of the indicator strip in detecting diclofenac sodium is with the occurrence of a color reaction. The PS and PMMA were made in the concentration of 5, 7.5 and 10% and the mixture of PS and PMMA 1:5 and 1:6 respectively with a ratio of solvent and reactant 6:4; 7:3 and 8:2. The best indicator strip is PMMA-CuSO 4 5% (7:3), PMMA-FeCl 3 5% (7:3) and PMMA-Vanillin sulphate 7.5% (7:3). The detection limit of the PMMA-CuSO 4 5% (7:3) was at 50 ppm, PMMA-FeCl 3 5% (7:3) showed detection limit of 12,500 ppm and PMMA-vanillin sulfate 7.5% (7:3) showed detection limit of 500 ppm. All indicator strips stable up to 29 weeks. The indicator strip can be used as an alternative method to detect diclofenac sodium in herbal medicine.
GSC 03588-09315 IS A LOW-AMPLITUDE DELTA SCUTI VARIABLE

Time-series observations of GSC 03588-09315 show it is a very low amplitude, multiperiodic delta Scuti variable at the limit of detectability. Five frequencies have been identified at 13.86819(24), 8.10026(79), 5.01966(79), 11.67281(55) and 8.17490(59) cycles d−1 with amplitudes of 10, 5, 5, 4, and 3 mmag respectively. The spectral energy distribution of the star is very closely matched to a spectral type of F0V, but it is probably 1. 3 brighter than a main-sequence star, so is likely to be evolved.
Essential Oil Quality and Purity Evaluation via FT-IR Spectroscopy and Pattern Recognition Techniques

Essential oils are highly volatile, aromatic concentrated extracts from plants with wide applications. In this study, fast, easy-to-use attenuated total reflection Fourier-transform infrared spectroscopy (ATR-FTIR) was combined with chemometric techniques to verify essential oils’ taxonomy and purity. Principal component analysis (PCA) clustered 30 essential oil samples into three different groups based on plant botanical family and concentration. The first group contained highly concentrated oils from the Asteraceae family, the second group contained highly concentrated oils from the Lamiaceae family, while the last group contained three highly concentrated essential oils from different botanical families and commercial-grade essential oils. Thus, commercial-grade oil samples did not cluster with the corresponding concentrated oil samples despite their similar spectral patterns or botanical family. A loading plot identified infrared (IR) bands that correspond to carbonyl, vinyl, methyl and methylene group vibrations as the most important spectral bands that can be used as marker bands for discrimination between different botanical plant family groups. Hierarchical cluster analysis (HCA) confirmed the results obtained by PCA. ATR-FTIR spectroscopy combined with chemometric algorithms provides a direct and non-destructive method for chemotaxonomic classification of medicinal and aromatic essential oils and an assessment of their purity.
The Utility of Information on Selective Exposure of Pornographic Information through Internet on Student of Islamic Boarding School in Tangerang City

This study wants to see the role of the utility of information on pornography among students in XYZ modern Islamic boarding school in Tangerang. This study uses a constructivist paradigm as a basis for thinking. The research method is a case study design using a qualitative approach. Data collection techniques using is in-depth interview methods. This type of interview allows researchers and informants to have a dialogue, and questions that have been prepared previously can be modified according to the informant's response. The results of the study showed that pornographic information could help students to have more understanding about reproductive health, and strengthen attitudes to reject pornographic information. Pornographic information is only useful to the increase knowledge related to sex education and not to be an indication of how to carry out sexual activities. Furthermore, the student stated information on important pornography, and was close to everyday life and they were very curious about pornography. However, all these things are only limited to understanding and knowledge about sex, not for sexual behavior. This is due to the upbringing of the Islamic boarding school which requires the student to submit and obey the rules of the Islamic boarding school.
