Ionic Conductivity of Cubic Solid Solutions in the System CaO—Y2O3—ZrO2

The ionic conductivity of cubic solid solutions in the system CaO -Y2O3-ZrO2 was examined. Particular Y2O3-ZrO2 binary compositions were more conductive at elevated temperatures (>600°C) than either CaO-ZrO2 binary or CaO-Y2O3-ZrO2 ternary compositions. The higher ionic conductivity appears to be related to a lower activation energy rather than to the number of oxygen vacancies dictated by composition. Those compositions of highest conductivity lie close to the cubic-monoclinic solid-solution phase boundary. Conductivity-temperature data are presented that indicate a reversible order-disorder transition for Y2O3-ZrO2 cubic solid solutions containing 20 and 25 mole % Y2O3. The transference number for the oxygen ion at 1000°C for Y2O2-ZrO2 cubic solid solutions is greater than 0.99.
The Effects of DER, ROA and DPR on Stock Price with EPS as the Moderating Variable in SOE

The present study aimed to determine the effects of financial ratio on stock price with EPS as the moderating variable. In the present study, the variables used to describe financial ratio were Debt to Equity Ratio (DER), Return On Asset (ROA), Dividend Payout Ratio (DPR) and Earning Per Share( EPS). The data used in the present study was secondary data in IDX and company annual report. The population used in the present study was banking companies listed in IDX in 2019-2018 period and are state-owned banks (SOE). The analysis technique was MRA (Moderated Regression Analysis) test. The research result showed that partially DER, ROA and EPS affected stock price, while DPR didn’t affect stock price. Simultaneously, DER, ROA and DPR affected stock price. Test on the moderating variable in the present study showed that the higher the EPS, the stronger the effects of ROA and DPR on stock price. In the present study, EPS is proven to be unable to moderate DER partially and unable to moderate DER, ROA and DPR simultaneously.

Antioxidant and antimicrobial activities of hydrophilic extracts from shallot and garlic bulbs, and their effects on round scad during iced storage

The present study aimed to investigate the in vitro antioxidant and antimicrobial activities of hydrophilic extracts prepared from shallot and garlic bulbs, and their effects on round scad during iced storage. Both the shallot and garlic extracts exhibited antioxidant activity concerning DPPH radical scavenging, total reducing power, and lipid peroxidation inhibition. The extracts also had antimicrobial activity against both Gram-positive (Bacillus cereus, Staphylococcus aureus) and Gramnegative (Escherichia coli, Salmonella typhimurium) pathogenic strains. Effects of treatment with the extracts on quality of round scad were evaluated by monitoring the total lipid hydroperoxides (HPO), thiobarbituric acid reactive substances (TBARS), total volatile basic nitrogen (TVB-N), total viable counts (TVC), and sensory characteristics. The spoilage indicators (HPO, TBARS, TVB-N, TVC) of the round scad treated with either shallot or garlic extracts were significantly suppressed during the ice storage period (P < 0.05). Round scad treated with either shallot or garlic extracts kept their natural sensory characteristics accepted for food-grade longer than 4 days of ice storage, compared with the control (without treatment). These results clearly show that the shallot and garlic extracts are potential natural preservatives, which can extend shelf-life of iced round scad.
Consistency and regularity of Chinese characters: Global congruence plays a more important role than local congruence in character naming

The concepts of consistency and regularity characterize the orthography-to-phonology mappings of written languages. The use of these two concepts arises, respectively, from the connectionist and classical cognitive modeling work in reading alphabetic languages. Consistency has been argued to better characterize the difficulty associated with English word naming than regularity (Jared, 2002). Despite writing system difference, the concepts of consistency and regularity have been imported to Chinese reading in prior research. However, the issue of the relative contributions of each in Chinese character naming is still unclear. The current ERP study examines this issue by manipulating orthogonally the consistency and regularity of Chinese characters in a covert naming task. The results show that consistency, but not regularity, affects the N170, P200 and N400 responses during word recognition as well as the accuracies of transcribing character pronunciations during posttest questionnaires. In addition, consistency interacts with regularity in modulating the FN400 and LPC responses. These results demonstrate that consistency plays a more important role than regularity in character naming, in agreement with the conclusion in English word naming. We suggest that the two concepts can be reframed as mapping congruence that applies to two levels: Consistency reflects GLOBAL level (usually multiple units) congruence among orthographic neighbors across the whole lexicon; regularity reflects the LOCAL level (specifically two units) congruence between a lexical unit and a single sublexical unit. Also, we illustrate their roles in an interactive framework of character recognition and discuss their impacts in this framework.

Selective Determination of p‐Nitrophenol Based on Its Unique Voltammetric Behavior on Nanoporous Gold

In this paper, an unsupported nanoporous gold (us-NPG) was applied as a novel electrochemical sensor material for the selective detection of p-nitrophenol (p-NP) among its isomers in acid solution based on the distinct cyclic voltammetric behavior. To ascertain the ascription of each peak in cyclic voltammograms (CVs) of three nitrophenol isomers (NPs) on the us-NPG, contrast voltammetric studies of NPs were conducted at an ultrathin NPG film supported on glassy carbon substrate (NPG/GC) and a well-defined Au(111) electrode, respectively. Effects of potential scan rate and rotation speed of the electrode on the redox reaction of NPs were investigated to further confirm the reaction mechanisms. Interestingly, unlike those obtained on NPG/GC and Au(111) electrodes, the CVs of both o-nitrophenol (o-NP) and m-nitrophenol (m-NP) on us-NPG presented a new pair of redox waves separated very well from the redox waves of p-NP, indicating an obviously different mechanism involved in the redox process. Based on the voltammetric behavior, trace level determination of p-NP can be achieved on us-NPG electrode in the presence of o-NP and m-NP. Thus, the fast electron transfer, high selectivity and good sensitivity make us-NPG act as an ideal electrochemical sensor material in the selective determination of p-NP in aqueous solutions.
About the relation between the empirical and the theoretically based parts of van der Waals-like equations of state

It is demonstrated that empirical temperature functionalities for the cohesive parameter in van der Waals-like equations can be responsible for prediction of nonphysical results such as fictitious critical points of pure compounds, that can result in prediction of unrealistic phase behavior in the entire thermodynamic phase space. Simple numerical tests for detecting this pitfall are proposed, and the roles played by the empirical and the theoretically based parts in semiempirical engineering equations are investigated. In particular, it is demonstrated that improvement of the accuracy with which equations of state approximate the hard sphere virial coefficients makes the theoretical part more self-sufficient for an accurate description of data. This significantly reduces the contribution of the corresponding empirical part and has a positive effect on the overall robustness and reliability of the model. In addition, an improved theoretical base contributes to the ability of the model so simultaneously and accurately predict both liquid and vapor densities.
H-Bond Breaking in High-Pressure Urea

Hydrogen bonds NH···O are broken and restored, and their lengths changed by more than 1 A in the strained crystal environment of urea, (NH2)2CO, when exposed to high pressure. Single crystals of urea phases I, III, and IV were grown in situ in a diamond-anvil cell, and their structures were determined by X-ray diffraction. At 0.48 GPa, on transformation from phase I (tetragonal space group P421m) to phase III (orthorhombic space group P212121), the channel voids characteristic of phase I collapse, one of the NH···O bonds is broken, and the H-acceptor capacity of the oxygen atom is reduced from 4 to 3. Above 2.80 GPa, in phase IV (orthorhombic space group P21212), the H-bonding pattern of phase I and fourfold H-acceptor oxygen are restored. The thermodynamic phase transitions in urea have been rationalized by a microstructural mechanism involving the interplay of pressure-induced molecular reorientations, with hydrogen bonds competing for access to lone-electron pairs of carbonyl oxygen, and by the increa.
Analysis of Student Abilities in Solving Mathematical Problems of National Examination at High School Level

The implementation of the National Examination (UN) is a government policy that aims to measure the competency achievement of graduates nationally on certain subjects, including mathematics. Mathematics with various roles makes it a very important science, among others, as a thinking tool to train students to solve or solve everyday problems. The purpose of this study is to analyze the ability, the type of error made, and the factors that cause students to make mistakes in completing math test questions. This type of research is qualitative research. The subjects in this study were Year 12 students of IPA 1 and IPA 3 of 11 students. The instruments in this study were mathematics questions of high school examinations year 2015/2016 that contained the indicator of problem solving and interview guidelines. Based on the analysis of test results and interviews, students' reasoning abilities in solving the National Examination are still low. Errors made by students include: 1) still mistakenly applying mathematical formulas and propositions in solving problems; 2) wrong in doing mathematical manipulation; 3) cannot draw logical conclusions; 4) cannot interpret questions into the form of mathematical models; and 5) wrong in using patterns and relationships to analyze mathematical situations. The factors that cause students to make mistakes include 1) students lack training independently by solving more varied questions; 2) material that has been studied is not well remembered, so mastery of the basic concepts of prerequisite material is still weak; 3) students tend to abbreviate answers and are not used to writing conclusions from an answer to a problem; 4) the existence of misconceptions in students; 5) students cheat on the work of other students; and 6) many students view mathematics as the most difficult field of study. Teachers are expected in learning activities to provide problems that demand students 'thinking reasoning in solving a problem so as to improve students' reasoning ability in solving math problems.

Fluorine-free blue-green emitters for light-emitting electrochemical cells

There is presently a lack of efficient and stable blue emitters for light-emitting electrochemical cells (LEECs), which limits the development of white light emitting systems for lighting. Cyclometalated iridium complexes as blue emitters tend to show low photoluminescence efficiency due to significant ligand-centred character of the radiative transition. The most common strategy to blue-shift the emission is to use fluorine substituents on the cyclometalating ligand, such as 2,4-difluorophenylpyridine, dFppy, which has been shown to decrease the stability of the emitter in operating devices. Herein we report a series of four new charged cyclometalated iridium complexes using methoxy- and methyl-substituted 2,3′-bipyridine as the main ligands. The combination of donor groups and the use of a cyclometalated pyridine has been recently reported for neutral complexes and found electronically equivalent to dFppy. We describe the photophysical and electrochemical properties of the complexes in solution and use DFT and TDDFT calculations to gain insights into their properties. The complexes exhibit bluish-green emission with onsets around 450 nm, which correspond to the maximum emission at 77 K. Furthermore, photoluminescence quantum yields in solution are all above 40%, with the brightest in the series at 66%. Finally, LEECs were prepared using these complexes as the emissive material to evaluate the performance of this particular design. Compared to previously reported devices with fluorine-containing emitters, the emitted colours are slightly red-shifted due to methyl substituents on the coordinating pyridine of the main ligand and overall device performances, unfortunately including the stability of devices, are similar to those previously reported. Interestingly within the series of complexes there appears to be a positive effect of the methoxy-substituents on the stability of the devices. The poor stability is therefore attributed to the combination of cyclometalated pyridine and methoxy groups.
Ammonia sensors based on metal oxide nanostructures

Ammonia sensing characteristics of nanoparticles as well as nanorods of ZnO, In2O3 and SnO2 have been investigated over a wide range of concentrations (1–800 ppm) and temperatures (100–300 °C). The best values of sensitivity are found with ZnO nanoparticles and SnO2 nanostructures. Considering all the characteristics, the SnO2 nanostructures appear to be good candidates for sensing ammonia, with sensitivities of 222 and 19 at 300 °C and 100 °C respectively for 800 ppm of NH3. The recovery and response times are respectively in the ranges 12–68 s and 22–120 s. The effect of humidity on the performance of the sensors is not marked up to 60% at 300 °C. With the oxide sensors reported here no interference for NH3 is found from H2, CO, nitrogen oxides, H2S and SO2.
Anàlisi poblacional i de distribució espacial de la Tortuga Mediterrània (Testudo hermanni) després d’una successió d’incendis a Son Doblons (Petra, Mallorca)

T. hermanni is a reptile considered of communitarian interest in Europe, because it is a threatened species. The species is distributed in specific places in the Mediterranean region, where fires are a common natural phenomenon. Currently, in the Balearic Islands the interdisciplinary ecology group of the UIB is the main entity that is dedicated to the studies of this species. Following this thematic line, this work aims to study the alterations that have caused a series of fires in a population of tortoise and their habitat in Son Doblons (Petra, Mallorca). To carry out these studies, the different mortality data that caused the fires were compared to know the repercussions they had on the population of T. hermanni. Next, a second comparison was made between the data of the surviving individuals of the last fire (2015) and the current population (2019). In this way it has been observed that the fires have produced a certain aging on the population of tortoise. Finally, a study has been made of the evolution of the vegetation caused by the fires and which is the current distribution of the species according to the type of vegetation. It has been observed that the tortoise shows a certain preference for areas of vegetation in transition that have not reached the last stage of the ecological succession.
Uso de Unidades de Memória em Redes Neurais Recorrentes para Acelerar a Otimização

In this work was made the modeling and the proposal of a memory unit to be incorporated into the structure of an artiﬁcial recurrent neural network. This structure was used to develop a program that aims to represent the intelligence of an intelligent agent capable of operating in partially observable environments. This proposal aims to accelerate and improve the convergence of recurrent neural networks, when applied to partially observable environments. The agent on concerned was applied to a modiﬁed version of prey predator problem. For this, a study was conducted about intelligent agents, task environments, recurrent neural networks, memory structures, and genetic algorithms. A memory unit has been modeled and implemented to be added to the structure of a recurrent neural network as well as the modeling and implementation of a framework of neural networks and other genetic algorithm framework, which was used to develop the program via the intelligence neural network.Finally was realized a computational model performance analysis with memory units applied to the problem predator and prey modiﬁed and inferred how close, or rather it was his performance in relation to conventional neural recurrent network. By analyzing the obtained results, it can be seen that the memory unit proposed in this work, added to the structure of a recurrent neural network, showed better performance and convergence time, compared with the conventional structure, increasing on average 1.55% the prey capture.

Photolytic Transformation of Organic Pollutants on Soil SurfacesAn Experimental Approach

Photolysis on soil surfaces is an important degradation pathway for many agrochemicals. Although the investigation of photochemical pesticide transformation on soil surfaces is required by registration authorities, knowledge of the relevant processes is limited. The quantification of photolysis on soil surfaces is of higher complexity than it is in solutions. In experiments, carried out on soil layers, the observed overall degradation rate is not only determined by photolysis itself but is also a function of the layer thickness and in many cases of transport processes. In this article we describe a theoretical framework to understand combined effects of these different processes, and we present an experimental setup that allows a separate quantification of actual photolysis and diffusive transport processes. For the two compounds p-nitroanisole and trifluralin we performed experiments on kaolinite layers of variable thickness and evaluated the results using a mathematical model. Thus, we were able to dete.
Heterogeneous interactions of chlorine nitrate, hydrogen chloride, and nitric acid with sulfuric acid surfaces at stratospheric temperatures

The heterogeneous interactions of ClONO2, HCl and HNO3 with sulfuric acid surfaces were studied using a Knudsen cell flow reactor. The surfaces studied, chosen to simulate global stratospheric particulate, were composed of 65-75% H2SO4 solutions at temperatures in the range −63 to −43°C. Heterogeneous loss, but not reaction, of HNO3 and HCl occurred on these surfaces and the measured sticking coefficients are reported. Chlorine nitrate reacted on the cold sulfuric acid surfaces, producing gas-phase HOCl and condensed HNO3. ClONO2 also reacted with HCl dissolved in the 65% H2SO4 solution at −63°C, forming gaseous Cl2. In all cases studied, the sticking and/or reaction coefficients were much larger for the 65% H2SO4 solution at −63°C than for the 75% solution at −43°C.
