Electrical properties of various aggregate states of matter

Electrical properties of solids are caused by elastic polarization of clusters in case of metals while those of dielectrics result from the orientation polarization of induced and built-in electric dipoles. Orientation polarization stems from the interaction of free built-in electric dipoles with an external electric field. A physical model of the dielectric permittivity formation of metals, electrolytes, plasma, ferrites, and ferroelectrics has been developed. Theoretical calculations of the dielectric permittivity of a number of ferrites and barium titanate have been performed in particular.

Calculations of hyperfine coupling constant of the TMPD molecule

Calculations of hyperfine coupling constant of the TMPD molecule The calculations of the hyperfine coupling constants (HFCC) of tetramethyl-p-Phenylenediamine (TMPD) are presented. Several DFT functionals are employed and the results are compared with the UHF and MP2 level of theory. Sensitivity of HFCC to the choice of the basis set is investigated. Impact of the different conformers of TMPD and the equivalence of methyl group hydrogens on the HFCC values is considered. The solvent effects are introduced via polarizable continuum model and compared with in vacuo calculations. Last but not least, molecular dynamics is employed to include the solvent molecules as well as the dynamics explicitly, accounting similar conditions comparing to the liquid phase EPR experiment.
A Model of Financial Shocks at Bank and Interbank of Iran ( DSGE )

This paper proposes a fully micro-founded framework that incorporates optimizing banks into a DSGE model, and evaluates the role of banks and financial shocks in the Iranian business cycles. We consider banks that offer different banking services and interact in an interbank market. Loans are produced using interbank borrowing and deposits. Banks have monopoly power, but cannot set nominal deposit and prime lending rates. The model also includes financial and unconventional monetary policy shocks. The main findings are: (1) Capturing the key features of the economy of Iran; (2) bank behavior substantially affects credit supply conditions and the transmission of different shocks; (3) financial shocks have significant effects on the Iranian business cycle fluctuations.
Sulfide geochronology along the Endeavour Segment of the Juan de Fuca Ridge

Forty‐nine hydrothermal sulfide‐sulfate rock samples from the Endeavour Segment of the Juan de Fuca Ridge, northeastern Pacific Ocean, were dated by measuring the decay of 226Ra (half‐life of 1600 years) in hydrothermal barite to provide a history of hydrothermal venting at the site over the past 6000 years. This dating method is effective for samples ranging in age from ∼200 to 20,000 years old and effectively bridges an age gap between shorter‐ and longer‐lived U‐series dating techniques for hydrothermal deposits. Results show that hydrothermal venting at the active High Rise, Sasquatch, and Main Endeavour fields began at least 850, 1450, and 2300 years ago, respectively. Barite ages of other inactive deposits on the axial valley floor are between ∼1200 and ∼2200 years old, indicating past widespread hydrothermal venting outside of the currently active vent fields. Samples from the half‐graben on the eastern slope of the axial valley range in age from ∼1700 to ∼2925 years, and a single sample from outside the axial valley, near the westernmost valley fault scarp is ∼5850 ± 205 years old. The spatial relationship between hydrothermal venting and normal faulting suggests a temporal relationship, with progressive younging of sulfide deposits from the edges of the axial valley toward the center of the rift. These relationships are consistent with the inward migration of normal faulting toward the center of the valley over time and a minimum age of onset of hydrothermal activity in this region of 5850 years.
Peptide conformational heterogeneity revealed from nonlinear vibrational spectroscopy and molecular dynamics simulations

Nonlinear time-resolved vibrational spectroscopy is used to compare spectral broadening of the amide I band of the small peptide trialanine with that of N-methylacetamide, a commonly used model system for the peptide bond. In contrast to N-methylacetamide, the amide I band of trialanine is significantly inhomogeneously broadened. Employing classical molecular-dynamics simulations combined with density-functional-theory calculations, the origin of the spectral inhomogeneity is investigated. While both systems exhibit similar hydrogen-bonding dynamics, it is found that the conformational dynamics of trialanine causes a significant additional spectral broadening. In particular, transitions between the poly(Gly)II and the αR conformations are identified as the main source of the additional spectral inhomogeneity of trialanine. The experimental and computational results suggest that trialanine adopts essentially two conformations: poly(Gly)II (80%) and αR (20%). The potential of the joint experimental and computational approach to explore conformational dynamics of peptides is discussed.
POSH-SHARP: A lightweight toolkit for creating cognitive agents

Agent design is an intricate process requiring skills from different disciplines. Thus experts in one domain are not necessarily experts in the others. Supporting the design of agents is important and needs to address varying skill and expertise as well as varying handling the design of complex agents. In this paper, a new agent design toolkit – POSH -SHARP– for intelligent virtual agents (IVAs) and cognitive embodied agents is presented. It was designed to address the need for a robust agent development framework in highly restrictive environments such as the web or smartphones while being useful to both novice and expert users. It includes advanced functionality such as debug support, explicit design rules using a related design methodology and a simple set-up and distribution mechanism to reduce the authoring burden for large iteratively developed agents. The new framework was implemented in C# and contains sample code for different game environments to offer novice users a starting point.
Brazing Behaviour of Ag-Cu Filler Materials

Ecological brazing rods (cadmium free) represent a technical solution particularly useful for joining metallic or non-metallic components, providing the required mechanical and functional characteristics obtained in reproducible manufacturing conditions and at rea- sonable costs. The new class of coated rods for brazing must provide high deposition effi -ciency, chemical compatibility in relation to a number of metals and alloys currently used in industry and high corrosion resistance in different media. Such diverse characteristics can be obtained by achieving a special coating that contains a mixture of materials having a role of chemical activation and catalyst effects, as well as contributing to increasing the adherence to unmolten interfaces. This chapter presents some results obtained by using experimental brazing filler materials for different types of materials and applications. There are briefly highlighted some aspects on the diffusion effects of chemical elements in the soldering interface, the bonding of ceramics and some issues related to the effects of chemical elements from the brazing material.
Ellipsis and dialogue in the early acquisition of syntax

The transition from the one and the two-word phases to the first complete sentences was investigated. Within an emergentist scope, it was hypothesized that it would be possible to identify transitional construc- tions, more complex than the mere juxtaposition of two words but syntac- tically less mature than simple sentences. Specifically, predominance of one and two-word productions, and a marginal use of correct but non- productive sentences were predicted, together with a gradual increase of syntactic fragments, i.e., correct and non-productive ellipses, given their frequent use in the Spanish language. Hypotheses were tested through a longitudinal study of a monolingual Spanish girl, from the age of 20 to 27 months. Weekly video sessions over seven months recorded her spontane- ous utterances. Those were coded together with their situational and speech contexts. The results supported and specified the hypothesis. Over time, there was an increased use of constructions we have called pre- ellipses because they mimic adult ellipses. Detailed analyses showed pre- elliptical constructions evolved from showing a local dependency on their production context, to becoming linked to the linguistic structure of the previous turn. Dialogue and its context played a fundamental role in these transitional steps into syntax.

Students ’ Attitudes towards the Concept of Equality and

Article History: Received 06.07. 2019 Received in revised form 03.08. 2019 Accepted 19.08. 2019 Available online 30.09. 2019 With the understanding of importance of pedagogical content knowledge, professional noticing has become one of the research subjects of the mathematics educators for the last 10 years. This qualitative study which explores secondary school students’ solution processes regarding the concept of equation ,one of the main components of algebraic learning field and the pre‐service teachers’ noticing about this is quite rich in terms of its results. The 6th, 7th, and 8th graders’ attitudes towards equations were revealed and it was found as stated in literature that students were dominantly “computational thinkers”. However, the differences in this general concept of thinking seem to make contribution to literature by involving discrete attitudes. In addition to this, the secondary findings of the study include some evidence revealing that pre‐service teachers’ level of noticing accumulates at middle levels but they can be improved. © 2019IJPES.

Social network usage, shame, guilt and pride among high school students: Model testing

This study was aimed at testing a model which applies structural equation modeling (SEM) to explain social networking sites (SNS) usage. Performing SEM with a sample of 500 high school students (40% male, 60% female), the model examined the relationships among shame, guilt and pride on SNS, such Facebook and Twitter. It was hypothesized that SNS usage was predicted directly by shame and indirectly by pride and guilt. The SEM showed that shame affected SNS usage directly and positively, while guilt and pride indirectly affected SNS via shame. The fit indices of SEM produced good fit values (χ2 = 0.11, df = 2, χ2/df = 0.055, p = 0.94532, RMSEA = 0.00, GFI = 1.00, AGFI = 1.00, NFI = 1.00, NNFI = 1.00, CFI = 1.00, IFI = 1.00, RMR = 0.039; SRMR = 0.0042). According to these results, high school students’ feelings of shame, guilt and pride are important predictors of SNS usage.
The Rhode Island Teen Institute: Positive Youth Development in Practice

This article describes the application of the positive youth development approach to promote and enhance leadership skills among middle and high school age peer leaders. The article reviews the goals of the positive youth development approach and describes how this approach was adopted and implemented by the Rhode Island Teen Institute (RITI), a comprehensive, residential prevention program founded in 1989. Data are presented from pretests and posttests administered during each of seven annual Institutes delivered between 2002 and 2009 with 775 youth. Participants in the RITI demonstrated significant gains in their leadership skills; an effect that persisted at a 3-month follow-up survey administered with high school age youth. Other significant findings and anecdotal effects are also discussed, such as creation by RITI graduates of a youth-led prevention program for elementary and middle school children.
Carbon Communities and Hotspots for Carbon Emissions Reduction in China

With China’s commitment to peak its emissions by 2030, sectoral emissions are under the spotlight due to the rolling out of the national emission trading scheme (ETS). However, the current sector policies focus either on the production side or consumption while the majority of sectors along the transmission were overlooked. This research combines input–output modelling and network analysis to track the embodied carbon emissions among thirty sectors of thirty provinces in China. Based on the large-data resolution network, a two-step network reduction algorithm is used to extract the backbone of the network. In addition, network centrality metrics and community detection algorithms are used to assess each individual sector’s roles, and to reveal the carbon communities where sectors have intensive emission links. The research results suggest that the sectors with high out-degree, in-degree or betweenness can act as leverage points for carbon emissions mitigation. In addition to the electricity sector, which is included in the national ETS, the study also found that the metallurgy and construction sectors should be prioritized for emissions reduction from national and local levels. However, the hotpots are different across provinces and thus provincial specific targeted policies should be formed. Moreover, there are nineteen carbon communities in China with different features, which provides direction for provincial governments’ external collaboration for synergistic effects.
Coal fly ash nanoparticles induced cytotoxicity and oxidative DNA damage and apoptosis in Chang liver cells

Coal is the main source widely used for electric generation and industrial applications due to its low cost and abundance of this fuel. Exposure to coal fly ash particulate matter (CFA-PM) is a major health concern in developing countries. The in vitro cytotoxicity, oxidative DNA damage and apoptosis of coal fly ash nanoparticles (CFA-NPs) were determined by lactate dehydrogenase (LDH) enzyme, reactive oxygen species (ROS), 4’-6-diamidino-2-phenylindole (DAPI) and expression of apoptosis associated proteins in cultured Chang liver cell lines. The release of LDH was increased based on dose-dependent and time dependent manner in CFA-NPS treated cells. CFA-NPs induced reactive oxygen species (ROS) with increase in dose concentration. The CFA-NPs treated cells showed severe DNA damage and inhibits the cell viability and leads to apoptosis. The apoptotic proteins showed significant changes, with increase in the level of BAX and decrease in the level of B-cell lymphoma 2 (Bcl-2). The studies showed significant amount of toxicity in CFA-NPs treated Chang liver cell lines. Key words: Coal fly ash nanoparticles, lactate dehydrogenase (LDH), reactive oxygen species, 4’-6-diamidino-2-phenylindole (DAPI), BAX, Bcl-2
Development and validation of consumer economic nationalistic tendencies scale (CENTSCALE)

Economic nationalism has been identified as a critical component of nationalistic sentiment, influencing cognitions, attitudes, evaluation and purchase intentions. While a distinction is made between economic nationalism and other measures of national and international orientation (ie. consumer ethnocentrism), previous empirical studies explore the concept in a ‘unified’ form. This study bridges this gap by developing a scale specifically tailored to measure consumer economic nationalistic tendencies. Scale generation, purification, validation and confirmation are achieved through five studies. Background and Problem Development Economic nationalism is described as the associated need with protectionism in the third world that involves discrimination in favour of one’s own nation (Macesich, 1985). It is the readiness to support nationalist economic policy, primarily adopting an ‘us first’, in-group versus out-group distinction (i.e. ‘domestic’ versus ‘foreign’ companies). In this case, it is proposed to be associated with personal job insecurity, authoritarianism, and intolerance of ambiguity (Baughn and Yaprak, 1996). Literature has also demonstrated that the term attributed to three components namely nationalism, patriotism and internationalism (Mort and Duncan, 2003; Kosterman and Feshback, 1989). In addition, some related the term to ethnocentrism, economic discrimination and even racism (see Becker, 1957; Ouellet, 2007; Adorno et al., 1960; Johnson, 1992), including the resistance to the immigration of foreign workers as well as to foreign investment; job utility, ownership of intellectual property and technological competitiveness (Macesich, 1985; Baugh and Yaprak, 1996). The construction of a unique scale is needed as current scales to measure economic nationalism by Baughn and Yaprak’s (1996) and Mort and Duncan, (2003) have little relevance to the study of consumer behaviour, in particular, consumer perspective of country ownership applications and related marketing functions. In developing a new measurement of consumer economic nationalism, the newly formed tendencies are closely associated with the purchasing of foreignversus domestic-owned product in relation to the need and importance to support the interest of domestic ownership (Mort and Duncan, 2003). As a result, the apprehension for economic security and power in conjunction with the importance of nationalistic tendencies and subsequently ownership implications are the basis for the conceptualization of consumer economic nationalism (CENT) (Baughn and Yaprak, 1996; Burnell, 1986; Mort and Duncan, 2003; Reich, 1991). The theoretical bases are derived from the realistic group conflict theory (RGCT) noting ‘competition over scare resources’ (Sherif et al. 1961; Jackson, 1993). As such, jobs and economic benefit constitute such highly competed-for resources (Insko et al., 1992), proposing that the consumer economic nationalism should include these two themes or factors.
A Neural Network Mark-up Estimation Model for Syrian Contractors

One of the most important decisions that have to be made by construction contractors is how much to mark-up the estimated cost of a new project. The main objectives of this paper are to model the relationship between mark-up estimation and the key factors affecting it and to compare the application of regression analysis and neural network techniques on the mark-up decision making process in order to find which technique is more reliable in terms of accuracy and robustness. The most influential mark-up factors were identified through a formal questionnaire survey conducted among Syrian contractors. Subsequently, data on one hundred and eleven real-life bidding situations was collected from Syria. Ninety-six of these projects were used to develop linear, non-linear regression and neural network mark-up models. The remaining fifteen projects were randomly held-back for validating the developed models. The neural network model proved to be robust and more accurate than the regression models. Although this study was carried out in the context of the Syrian construction industry, the methodology and the findings have much broader geographical applicability.
Modeling and Design of a SiC Zero Common-Mode Voltage Three-Level DC/DC Converter

As wide-bandgap devices continue to experience deeper penetration in commercial applications, there are still a number of factors which make the adoption of such technologies difficult. One of the most notable issues with the application of widebandgap technologies is meeting existing noise requirements and regulations. Due to the faster dv/dt and di/dt of SiC devices, more noise is generated in comparison to Si IGBTs. Therefore, in order to fully experience the benefits offered by this new technology, the noise must either be filtered or mitigated by other means. A survey of various DC/DC topologies was conducted in order to find a candidate for a battery interface in a UPS system. A three-level NPC topology was explored for its potential benefit in terms of noise, efficiency, and additional features. This converter topology was modeled, simulated, and a hardware prototype constructed for evaluation within a UPS system, although its uses are not limited to such applications. A UPS system is a good example of an application with strict noise requirements which must be fulfilled according to IEC standards. Based on a newly devised mode of operation, this converter was verified to produce no common-mode voltage under ideal conditions, and was able to provide a 6 dB reduction in common-mode voltage emissions in the UPS prototype. This was done while achieving a peak efficiency in excess of 99% with the ability to provide bidirectional power flow between the UPS and battery backup. The converter was verified to operate at the rated UPS conditions of 20 kW while converting between a total DC bus voltage of 800 V and a nominal battery voltage of 540 V.
