Bulk flow in the combined 2MTF and 6dFGSv surveys

We create a combined sample of 10 904 late- and early-type galaxies from the 2MTF and 6dFGSv surveys in order to accurately measure bulk flow in the local Universe. Galaxies and groups of galaxies common between the two surveys are used to verify that the difference in zero-points is <0.02 dex. We introduce a maximum likelihood estimator (eta MLE) for bulk flow measurements that allows for more accurate measurement in the presence of non-Gaussian measurement errors. To calibrate out residual biases due to the subtle interaction of selection effects, Malmquist bias and anisotropic sky distribution, the estimator is tested on mock catalogues generated from 16 independent large-scale GiggleZ and SURFS simulations. The bulk flow of the local Universe using the combined data set, corresponding to a scale size of 40 h(-1) Mpc, is 288 +/- 24 km s(-1) in the direction (l, b) = (296 +/- 6 degrees, 21 +/- 5 degrees). This is the most accurate bulk flow measurement to date, and the amplitude of the flow is consistent with the Lambda cold dark matter expectation for similar size scales.
On side refrigerant measurement of heat pump seasonal performances

Heat pump systems have become very popular for space heating in the residential sector in Europe. However, there is no data available on the in situ seasonal heating performances of air-to-air heat pumps. This is due to the difficulty of measuring their thermal capacity on field over a long period. Several methods relying on air flow rate and enthalpy measurements are being considered for in-situ measurement for air-to-air heat pumps. But accuracy and reliability of these methods are still unknown. In this paper, we show the results of a method based on intrusive measurements (on the refrigerant side) adapted to the dynamic behavior. This method uses Coriolis flow meters measures for the refrigerant flow rate and for enthalpies. Results confirm that the refrigerant density measurement with a Coriolis flow meter can help to predict the refrigerant vapor quality with a satisfying accuracy if the quality is not too high. The method is validated by testing an air-to-water heat pump in laboratory and by using the water enthalpy method as a reference. The experimental results show that the method is reliable in dynamic conditions (including during the defrosting periods). This internal method can be used as a reference to check the air enthalpy method for air-to-air heat pumps.
Mechanisms and Modelling of Microstructure/Texture Evolution in Interstitial-free Steel Sheets

Evidence relating to mechanisms of recrystallisation and associated texture evolution in low carbon steels is briefly reviewed and some new observations are presented. These viewpoints are taken as the starting point for development of a computer model that can be used to predict the effects of steel chemistry and process parameters on the grain structures and textures of titanium-stabilised interstitial-free steel sheets. The model utilises physical principles as far as possible and combines these with empirical descriptions where necessary, fitting these with the aid of experimental data. Assumptions made in the model are clearly described.
The Cognitive Perspective on Learning: Its Theoretical Underpinnings and Implications for Classroom Practices

Abstract Learning theories are essential for effective teaching in that they shed light on different aspects of the learning process. The spectrum of learning theories can be categorized into three main areas: behaviorism, cognitivism, and constructivism. Behaviorism as a teacher-centered instructional framework for a long time dominated educational settings, shaping every aspect of curriculum and instruction. In contrast to behaviorism, cognitivism is a relatively recent learning theory and its features are not well known or are confused with constructivism by teachers. This article aims to provide an overview of the core characteristics of cognitivism, its philosophical and theoretical basis, its implications for classroom practices, and its illustrative teaching methods. Cognitive apprenticeship, reciprocal teaching, anchored instruction, inquiry learning, discovery learning, and problem-based learning are explicated as the most distinctive methods of the cognitive perspective on learning.
An Ordinary Short Gamma-Ray Burst with Extraordinary Implications: Fermi-GBM Detection of GRB 170817A

On 2017 August 17 at 12:41:06 UTC the Fermi Gamma-ray Burst Monitor (GBM) detected and triggered on the short gamma-ray burst (GRB) 170817A. Approximately 1.7 s prior to this GRB, the Laser Interferometer Gravitational-wave Observatory triggered on a binary compact merger candidate associated with the GRB. This is the first unambiguous coincident observation of gravitational waves and electromagnetic radiation from a single astrophysical source and marks the start of gravitational-wave multi-messenger astronomy. We report the GBM observations and analysis of this ordinary short GRB, which extraordinarily confirms that at least some short GRBs are produced by binary compact mergers.
Semiclassical analysis for highly degenerate potentials

This paper characterizes the semi-classical limit of the fundamental energy, E(h) :=σ 1 [-h 2 Δ+α(x));Ω], and ground state ψ h of the Schrodinger operator -h 2 Δ + a in a bounded domain Ω, in the highly degenerate case when a ≥ 0 and a -1 (0) consists of two components, say Ω 0,1 and Q 0,2 . The main result establishes that lim h↓0 E(h) h 2 =min {σ1[-Δ;Ω0,i],i=1,2} and that ψ h approximates in H 0 1 (Ω) the ground state of -A in Q 0,i if σ 1 [-Δ;Ω0,i]
Ab initio design of new cobalt-based half-Heusler materials for thermoelectric applications

In search of new prospects for thermoelectric materials, using ab-initio calculations and semi-classical Boltzmann theory, we have systematically investigated the electronic structure and transport properties of 18-valence electron count cobalt based half-Heusler alloys with prime focus on CoVSn, CoNbSn, CoTaSn, CoMoIn, and CoWIn. The effect of doping on transport properties has been studied under the rigid band approximation. The maximum power factor, S$^2\sigma$, for all systems is obtained on hole doping and is comparable to the existing thermoelectric material CoTiSb. The stability of all the systems is verified by phonon calculations. Based on our calculations, we suggest that CoVSn, CoNbSn, CoTaSn, CoMoIn and CoWIn could be potential candidates for high temperature thermoelectric materials.
The walls speak: the interplay of quality facilities, school climate, and student achievement

Purpose – A growing body of research connecting the quality of school facilities to student performance accompanies recent efforts to improve the state of the educational infrastructure in the USA. Less is known about the mechanisms of these relationships. This paper seeks to examine the proposition that part of the explanation may be the mediating influence of school climate.Design/methodology/approach – Teachers from 80 Virginia middle schools were surveyed employing measures including the School Climate Index, a seven‐item quality of school facilities scale, as well as three resource support items. Data on student SES and achievement were also gathered. Bivariate correlational analysis was used to explore the relationships between the quality of facilities, resource support, school climate, student SES, and student achievement. In addition, multiple regression was used to test school climate as a mediating variable between the quality of facilities and student achievement.Findings – Results confirmed a.
Pedagogy with interactive whiteboards : perspectives of business education teachers

This study examined the perceptions of Botswana secondary school business education teachers on the use of interactive whiteboards (IWBs) in the classroom. It focused on teachers' confidence and competence levels on use of IWBs, the attitudes towards the use of IWB as a tool of instruction, and their perceptions on the impact of IWBs on students' learning. The findings from the study suggest that a majority of teachers were confident and competent in of the use of computers, and thus could confidently integrate them into their classroom teaching. Furthermore, teachers indicated that they were fairly competent in the use of IWBs because they received sufficient on-the-job training which was mostly from suppliers of IWBs, and to a lesser extent from professional development workshops and self-training. Despite their professed competency, most teachers were neither confident nor comfortable integrating IWBs in their teaching practices. As pedagogical tools, most teachers perceived IWBs as having a positive impact on student learning. They purported that IWBs increased learner interest, engagement and motivation. They also believed that they contribute to making lessons become more interactive and action-oriented through heightened student participation in discussions and other classroom activities. As educators are continuously seeking innovative ways to make learning interesting, interactive and actively engaging for learners, this study shows that IWBs wield the potential to achieve this. It also highlights the need to invest in training teachers on the effective use of IWBs to boost their competency levels, confidence and attitudes towards their use in classroom instruction.
Regional dynamics of forest canopy change and underlying causal processes in the contiguous U.S.

The history of forest change processes is written into forest age and distribution and affects earth systems at many scales. No one data set has been able to capture the full forest disturbance and land use record through time, so in this study, we combined multiple lines of evidence to examine trends, for six US regions, in forest area affected by harvest, fire, wind, insects, and forest conversion to urban/surburban use. We built an integrated geodatabase for the contiguous U.S. (CONUS) with data spanning the nation and decades, from remote sensing observations of forest canopy dynamics, geospatial data sets on disturbance and conversion, and statistical inventories, to evaluate relationships between canopy change observations and casual processes at multiple scales. Results show the variability of major change processes through regions across decades. Harvest affected more forest area than any other major change processes in the North East, North Central, Southeast, and South central regions. In the Pacific Coast and Intermountain West, more forest area was affected by harvest than forest fires. Canopy change rates at regional scales confounded the trends of individual forest change processes, showing the importance of landscape scale data. Local spikes in observed canopy change rates were attributed to wind and fire events, as well as volatile harvest regimes. This study improves the geographic model of forest change processes by updating regional trends for major disturbance and conversion processes and combining data on the dynamics of fire, wind, insects, harvest, and conversion into one integrated geodatabase for the CONUS.
Management strategy and intellectual capital disclosure: Influence of corporate governance

Knowledge has become a key strategic resource for business success and has led companies to be concerned about managing their knowledge assets (intellectual capital). However, accounting as an information system has suffered a loss of reliability of the information provided, by showing that the market value of companies is higher than the book value shown in the balance sheets. This discrepancy has been one of the main reasons why companies voluntarily manage and disclose their intellectual capital. Relying on the agency theory and the resources and capabilities theory, this paper analyses the influence of corporate governance in the management of information intellectual capital. The methodology used was based on content analysis of annual reports using a analysis multivariate linear regression
Application of Fourier Function to Double Divisor Ratio Spectra Curves forAnalysis of Some Amoebicide Drugs in Their Ternary Mixtures

This work concerns with development of spectrophotometric methods for analysis of Metronidazole, Diloxanide Furoate and Mebeverine HCl. Method (I) is double divisor ratio spectra derivative method (DDRD) which depends on using derivative signals of the ratio spectra using double divisor. Method (II) is hybrid double divisor ratio spectra (HDDR) which depends on convolution of the double divisor ratio spectra using trigonometric Fourier functions. The developed HDDR method showed better selectivity than DDRD due to its higher resolution power. The methods have been applied for analysis of the studied drugs in their commercial tablets and the results obtained from the analysis of the market sample by the proposed methods were statistically compared with those obtained by manufacturer RP-HPLC method.
Three-Dimensional CFD Simulation of Fluid Flow inside a Vortex Tube on Basis of an Experimental Model- The Optimization of Vortex Chamber Radius

Vortex-chamber is a main part of vortex tube which the pressured gas is injected into this part tangentially. An appropriate design of vortex-chamber geometry leads to better efficiency and good vortex tube performance. In this study, the computational fluid dynamics (CFD) model is created on basis of an experimental model and is a three-dimensional (3D) steady compressible model that utilizes the k-e turbulent model. In this paper the effect of changing radius of vortex-chamber (R*) on vortex tube performance has been studied for different value of R* and the optimized radius of vortex-chamber has been determined. According to numerical results the cold temperature difference has increased when we take into account the effect of the radius of vortex-chamber in range of 5.7-11 mm and when the radius of vortex chamber has located in range of 11-13 mm, the cold temperature difference has decreased. The highest ΔTc is 46.77 K for R*=11 mm at a cold mass fraction of 0.3, higher than basic model around 6.3% at the same cold flow fraction. Finally, the results obtained, particularly the temperature values, are compared with some available experimental data, which show good agreement.
A Novel Coaxial Borehole Heat Exchanger: Description and First Distributed Thermal Response Test Measurements

The thermal performance of a Borehole Heat Exchanger plays a significant role when defining the quality of heat exchange with the ground in Ground Source Heat Pumps. Different designs have been discussed and increased interest on innovation within this field has taken place during the last years. This paper presents the first measurement results from a 189 meters deep novel coaxial Borehole Heat Exchanger, consisting of an inner central pipe and an annular channel in direct contact with the surrounding bedrock. The measurements were taken during a distributed thermal response test using fiber optic cables installed in the energy well. Fluid temperature every ten meters along the borehole depth are presented and compared with similar measurements from a common U-pipe heat exchanger. A unique measurement of the borehole wall temperature in the coaxial collector illustrates how effective the heat transfer performance is through the annular channel.
FORWARD AND INVERSE MODELLING OF GEOTHERMAL MICROSEISMICITY USING TOUGH 2 COUPLED WITH AN EARTHQUAKE SIMULATOR

Reservoir modelling is undertaken to represent the physical state of the reservoir in order to estimate its current condition and to predict future responses. Prior to use of the reservoir model for forecasting, it is common to calibrate natural state and production models using temperature and pressure data gathered from downhole surveys. In addition to these data, microseismicity presents a further opportunity to calibrate reservoir parameters, in particular the permeability of active faults that serve as major fluid pathways. Microearthquakes (MEQs) occur in areas where brine produced from the production wells is reinjected. The injection causes fluid pressure to build-up in the area, which decreases the rock yield strength and promotes failure: a small earthquake. These events may occur on active faults that are also major fluid pathways in the field. The location, migration, and number of MEQs provide information about pressure change and the nature of fluid flow through the reservoir. Many fields these days are equipped with instruments to detect and locate MEQs. The objective of this project is to integrate MEQ data into the reservoir model development workflow so as to assist model calibration and reservoir characterization. In this project, a simple reservoir model is created to represent an area into which fluid is injected. A forward run using the TOUGH2 reservoir simulator is conducted to estimate pressure changes due to injection into a single well for specified reservoir and fault parameters. Pressure change on the fault is used to compute an average seismicity rate as well as individual MEQ locations and times. Sensitivity analysis has been conducted to understand how model parameters affect the amount of seismicity generated, and the manner in which it travels along the fault. The coupling between reservoir pressure evolution and synthetic microseismicity provides the physical link necessary to use field MEQ data for calibration. In particular, we will use the seismicity migration rate to estimate permeability of the reservoir and faults. The synthetic study presented here is a proof-ofconcept before application of the approach to an actual geothermal MEQ dataset.
Debt/Equity Ratio and Expected Common Stock Returns: Empirical Evidence

The expected common stock returns are positively related to the ratio of debt (noncommon equity liabil ities) to equity, controlling for the beta and firm size and includin g as well as excluding January, though the relation is much larger in January. This relationship is not sensitive to variations in the mar ket proxy, estimation technique, etc. The evidence suggests that the "premium" associated with the debt/equity ratio is not likely to be just some kind of "risk premium.

A Critical Analysis of Matrix Task Classificatory and Seriation Abilities.

ABSTRACT Two experiments which investigated the young child's ability to deal with multiplicative classes, and relations (considered behavioral indices of concrete operations thought) in double series and cross class matrices are described and discussed. In the initial Study,-1-60 children from preschool through grade 2 received six matrix subtasks (reproduction and transposition subtasks of cross classification, classification seriation, and double seriation) in one of six orders of presentation (the reproduction subtask always preceded the transposition case for a given matrix). The second experiment followed much the same design as the first, except that the class/series matrix was not used and stimuli for one cross class task were rearranged so that neither dimension was seriated across rows or columns of the matrix. Results, conclusions, and methodological problems of each experiment are discussed in detail. It was concluded that the pattern of lesser general difficulty for multiple relations contrasted with multiple classification concepts was subtantiated in these experiments (and other experiments (and other experiments also discussed) and that the original structural synchrony conclusions of Inhelder and Piaget need further examination.

Special Review Article: Beyond culture or beyond control? Reviewing the use of Hall’s high-/low-context concept

This paper reviews Edward T. Hall’s influential concept of high-/low-context communication and its use in cross-cultural research. Hall’s concept suggests that individuals combine preprogrammed culture specific context and information to create meaning. The use of context is argued to vary across cultures and country classifications have been attached to Hall’s concept. These country rankings have evolved over time classifying (national) cultures as ‘high-context’ (HC) and ‘low-context’ (LC). Since future studies employing Hall’s context idea as an underlying framework in cross-cultural research need to rely on a valid and reliable country classification, our study analyses literature related to Hall’s HC/LC concept. Based on a systematic review, we particularly question whether the country classification attached to Hall’s concept is built on rigorous and substantiated findings. Our study shows that most previous research that utilized HC/LC country classifications is based on seemingly less-than-adequate evidence. Mixed and often contradictory findings reveal inconsistencies in the conventional country classifications and show that they are flawed or, at best, very limited.
Functional renormalization group approach to SU(N) Heisenberg models: Real-space renormalization group at arbitrary N

The pseudofermion functional renormalization group (pf-FRG) is one of the few numerical approaches that has been demonstrated to quantitatively determine the ordering tendencies of frustrated quantum magnets in two and three spatial dimensions. The approach, however, relies on a number of presumptions and approximations, in particular the choice of pseudofermion decomposition and the truncation of an infinite number of flow equations to a finite set. Here we generalize the pf-FRG approach to SU(N)-spin systems with arbitrary N and demonstrate that the scheme becomes exact in the large-N limit. Numerically solving the generalized real-space renormalization group equations for arbitrary N, we can make a stringent connection between the physically most significant case of SU(2)-spins and more accessible SU(N) models. In a case study of the square-lattice SU(N) Heisenberg antiferromagnet, we explicitly demonstrate that the generalized pf-FRG approach is capable of identifying the instability indicating the transition into a staggered flux spin liquid ground state in these models for large, but finite values of N. In a companion paper (arXiv:1711.02183) we formulate a momentum-space pf-FRG approach for SU(N) spin models that allows us to explicitly study the large-N limit and access the low-temperature spin liquid phase.
