TORUS AND ACTIVE GALACTIC NUCLEUS PROPERTIES OF NEARBY SEYFERT GALAXIES: RESULTS FROM FITTING INFRARED SPECTRAL ENERGY DISTRIBUTIONS AND SPECTROSCOPY

We used the CLUMPY torus models and a Bayesian approach to fit the infrared spectral energy distributions and ground-based high angular resolution mid-infrared spectroscopy of 13 nearby Seyfert galaxies. This allowed us to put tight constraints on torus model parameters such as the viewing angle i, the radial thickness of the torus Y, the angular size of the cloud distribution σtorus, and the average number of clouds along radial equatorial rays N0. We found that the viewing angle i is not the only parameter controlling the classification of a galaxy into type 1 or type 2. In principle, type 2s could be viewed at any viewing angle i as long as there is one cloud along the line of sight. A more relevant quantity for clumpy media is the probability for an active galactic nucleus (AGN) photon to escape unabsorbed. In our sample, type 1s have relatively high escape probabilities, Pesc ∼ 12%–44%, while type 2s, as expected, tend to have very low escape probabilities. Our fits also confirmed that the tori of Seyfert galaxies are compact with torus model radii in the range 1–6 pc. The scaling of the models to the data also provided the AGN bolometric luminosities Lbol(AGN), which were found to be in good agreement with estimates from the literature. When we combined our sample of Seyfert galaxies with a sample of PG quasars from the literature to span a range of Lbol(AGN) ∼ 1043–1047 erg s−1, we found plausible evidence of the receding torus. That is, there is a tendency for the torus geometrical covering factor to be lower (f2 ∼ 0.1–0.3) at high AGN luminosities than at low AGN luminosities (f2 ∼ 0.9–1 at ∼1043–1044 erg s−1). This is because at low AGN luminosities the tori appear to have wider angular sizes (larger σtorus) and more clouds along radial equatorial rays. We cannot, however, rule out the possibility that this is due to contamination by extended dust structures not associated with the dusty torus at low AGN luminosities, since most of these in our sample are hosted in highly inclined galaxies.
The Influence of Environment on Solar Chimney Power Plant Performance

R & D Journal, of the South African Institution of Mechanical Engineering 2009, 25 http://www.saimeche. org.za (open access) 1 This paper investigates the effects of ambient wind, temperature lapse rates and nocturnal temperature inversions on the performance of a large-scale solar chimney power plant. The effect of prevailing ambient winds at a reference site on plant performance is evaluated, while different ambient wind profile models are also considered. During the daytime, the atmosphere surrounding the plant is modelled using a dry adiabatic lapse rate (DALR) and the International Standard Atmosphere (ISA), while night-time temperature inversion effects are also accounted for. Results indicate that windy conditions impair plant performance considerably, while nocturnal temperature inversions cause significant reductions in night-time output.
Quantum diffusion during inflation and primordial black holes

We calculate the full probability density function (PDF) of inflationary curvature perturbations, even in the presence of large quantum backreaction. Making use of the stochastic-δ N formalism, two complementary methods are developed, one based on solving an ordinary differential equation for the characteristic function of the PDF, and the other based on solving a heat equation for the PDF directly. In the classical limit where quantum diffusion is small, we develop an expansion scheme that not only recovers the standard Gaussian PDF at leading order, but also allows us to calculate the first non-Gaussian corrections to the usual result. In the opposite limit where quantum diffusion is large, we find that the PDF is given by an elliptic theta function, which is fully characterised by the ratio between the squared width and height (in Planck mass units) of the region where stochastic effects dominate. We then apply these results to the calculation of the mass fraction of primordial black holes from inflation, and show that no more than ∼ 1 e-fold can be spent in regions of the potential dominated by quantum diffusion. We explain how this requirement constrains inflationary potentials with two examples.
A Synergetic Approach for the Space-Based Sea Surface Currents Retrieval in the Mediterranean Sea

We present a method for the remote retrieval of the sea surface currents in the Mediterranean Sea. Combining the altimeter-derived currents with sea-surface temperature information, we created daily, gap-free high resolution maps of sea surface currents for the period 2012–2016. The quality of the new multi-sensor currents has been assessed through comparisons to other surface-currents estimates, as the ones obtained from drifting buoys trajectories (at the basin scale), or HF-Radar platforms and ocean numerical model outputs in the Malta–Sicily Channel. The study yielded that our synergetic approach can improve the present-day derivation of the surface currents in the Mediterranean area up to 30% locally, with better performances for the the meridional component of the motion and in the western section of the basin. The proposed reconstruction method also showed satisfying performances in the retrieval of the ageostrophic circulation in the Sicily Channel. In this area, assuming the High Frequency Radar-derived currents as reference, the merged multi-sensor currents exhibited improvements with respect to the altimeter estimates and numerical model outputs, mainly due to their enhanced spatial and temporal resolution.
Environmental factors influencing odonata communities of three mediterranean rivers : Kebir-East, Seybouse, and Rhumel Wadis, northeastern Algeria

RÉSUMÉ. — Facteurs environnementaux influençant les communautés d’Odonates de trois rivières méditerranéennes : les oueds Kebir-Est, Seybouse et Rumel, nord-est algérien. — Les Odonates sont une composante importante des peuplements des milieux lotiques et leur abondance et diversité renseignent sur l’intégrité écologique de ces hydrosystèmes. L’inventaire odonatologique de trois oueds majeurs algériens : KebirEst, Seybouse et Rhumel, a permis l’identification de 40 espèces. Nos résultats révèlent la présence de Calopteryx exul, endémique maghrébin, dans l’oued Seybouse et semblent confirmer l’extinction de la population type dans l’oued Rhumel où l’espèce avait été découverte au XIXe siècle. Nos résultats indiquent également l’expansion de plusieurs espèces: Coenagrion caerulescens, Orthetrum nitidinerve, Trithemis kirbyi et Urothemis edwardsii dont la population relictuelle est en danger critique d’extinction. La mesure de diverses variables physicochimiques (altitude, température, conductivité, etc.) nous a permis d’explorer une possible co-structure entre les jeux de données faunistiques et de variables environnementales. L’analyse des données indique que la richesse spécifique est, selon l’oued, variablement correlée à l’hydropériode, à la conductivité et à la température de l’eau, suggérant son utilité dans l’évaluation de l’intégrité écologique des cours d’eau méditerranéens.
Thermal maturity of the axial zone of the southern Apennines fold‐and‐thrust belt (Italy) from multiple organic and inorganic indicators

The reconstruction of the thermal history of folded and thrust units is crucial to define the pattern of tectonic loading and the time‐space evolution of an orogen where tectonic exhumation processes occurred at shallow crustal levels. In the present study, a well‐constrained reconstruction of the thermal maturity in the axial zone of the southern Apennines has been achieved by the combined use of different thermal indicators in diagenesis. The major results are: (i) documentation of a jump in thermal maturity from the Apenninic Platform derived tectonic unit (from immature to early mature stages of hydrocarbon maturation) to the Lagonegro Basin derived tectonic units (late diagenetic zone); (ii) documentation of along‐strike slighter variations in the Lagonegro units, concerning thermal maturity (thus maximum burial temperatures). This can be related to changes in amounts of tectonic burial and erosion/exhumation because of the lack of cylindricity of contractional structures; (iii) recognition of an independent thermal evolution of the allochthonous chain compared with the Apulian Platform tectonic unit with Mt Alpi area (in the late mature stage of hydrocarbon generation) interpreted as a sector of localized, intense exhumation within the External Zone of the orogen.
Enhancement of Methane Concentration by Removing Contaminants from Biogas Mixtures Using Combined Method of Absorption and Adsorption

We report a laboratory scale combined absorption and adsorption chemical process to remove contaminants from anaerobically produced biogas using cafeteria (food), vegetable, fruit, and cattle manure wastes. Iron oxide (Fe2O3), zero valent iron ( ), and iron chloride (FeCl2) react with hydrogen sulfide (H2S) to deposit colloidal sulfur. Silica gel, sodium sulfate (Na2SO4), and calcium oxide (CaO) reduce the water vapour (H2O) and carbon dioxide (CO2). It is possible to upgrade methane (CH4) above 95% in biogas using chemical or physical absorption or adsorption process. The removal efficiency of CO2, H2S, and H2O depends on the mass of removing agent and system pH. The results showed that Ca(OH)2 solutions are capable of reducing CO2 below 6%. The H2S concentration was reduced to 89%, 90%, 86%, 85%, and 96% for treating with 10 g of FeCl2, (with pH), Fe2O3, , and activated carbon, respectively. The H2O concentration was reduced to 0.2%, 0.7%, 0.2%, 0.2%, and 0.3% for treating raw biogas with 10 g of silica gel and Na2SO4 for runs R1, R2, R3, R4, and R5, respectively. Thus, given the successful contaminant elimination, the combined absorption and adsorption process is a feasible system for biogas purification.

Being a graduate professional in the field of Early Childhood Education and Care: silence, submission and subversion

ABSTRACT Recent workforce reform in England has sought to increase opportunities for practitioners who work outside the maintained (school) sector to gain graduate status. Whilst these opportunities have generally been welcomed within the sector, this has created dichotomous tensions for the ECEC workforce. The traditional construction of the ECEC practitioner assumes a lack of educational and social capital [Osgood, J. 2009. “Childcare Workforce Reform in England and ‘the Early Years Professional’: A Critical Discourse Analysis. ” Journal of Education Policy 24 (6): 733–751. doi:10.1080/02680930903244557]. Its associated dispositions do not necessarily fit with the alternative construct of the Early Years Professional or Teacher who, through gaining educational capital in the form of a university degree, will be sufficiently equipped to enact the normative and performative discourses which dominate educational and social policy. These tensions serve as the focus for this study, which was concerned with examining how a group of graduate practitioners were endeavouring to broker their competing professional constructs within their own workplace. The research argues for the necessity to establish professional, relational spaces within and across the field of Early Years Education and Care in order to have a greater understanding of the value that all early years professionals can contribute to pedagogical practice.
Reliability estimation of k-unit series system based on progressiverly censored data

In this article, we consider a k-unit series system with component lifetime distribution to be a member of the scale family of distributions. We discuss estimation of the scale parameter and estimation of reliability function of the family based on progressively Type-II censored sample. The maximum likelihood estimator (MLE) of the scale parameter is derived using Expectation-Maximization (EM) algorithm and is used to estimate reliability function. Confidence intervals are constructed using asymptotic distribution of MLE. β-expectation tolerance interval for lifetime of the system is obtained. We consider half-logistic distribution as a member of the scale family and study performance of the MLE, reliability estimate and confidence interval using simulation experiments.
Influential Factors of KM Process Adoption: A Social-technological Based Approach

KM, in a nutshell, means doing what is needed to get the most out of knowledge resources [1]. In an organisational context, KM means, any intentional and systematic process or practice of acquiring, capturing, sharing and using productive knowledge, wherever it resides, to enhance learning and performance in organisations [2]. Evidence from literature indicates that organisations tend to pursue efforts in KM conceptualization and initiatives through either human (personalization) or system (codification) approach [3, 4]. Arguably, this segmented approach to KM could result in low KM implementation success rate due to the nature of high dependency between human and technological factors [5, 6]. This somewhat explains the need for process-oriented approach as suggested by Grover and Davenport [4].

Fixed Point Theorem and Fractional Differential Equations with Multiple Delays Related with Chaos Neuron Models

In this paper, we show a fixed point theorem which deduces to both of Lou’s fixed point theorem and de Pascale and de Pascale’s fixed point theorem. Moreover, our result can be applied to show the existence and uniqueness of solutions for fractional differential equations with multiple delays. Using the theorem, we discuss the fractional chaos neuron model.
Understanding the motivations for return migration in Australia

Background Return migration is often overlooked by traditional analyses of internal migration. Why people return has received even less scrutiny. Relatively few migrants make a return move, so there is clearly something noteworthy about these people and their circumstances that trigger such a move.Aims This paper explores why people make return moves in Australia. Data and methods Migration histories were collected using semi-structured in-depth interviews; content analysis of interview transcripts was undertaken.Results People return for a wider range of reasons than is indicated by neoclassical economic theory. Some of the moves are linked to significant life events such as post-school education and employment. Returns also occur for less tangible factors such as amenity and climate, connections to family, friends and the extent to which a place “feels like home” are equally important.Conclusions A broader explanatory framework is required to explain why people return. The integration of migrant stories into more traditional migration analyses enriches the story of internal migration.
Features of Women’s Leadership and Nursing in Japanese Culture

Abstract Mutual respect and harmonious relationships between people can be viewed as the fundamental spirit of Japanese culture. Japanese leaders try to keep the peace in human relations, rather than to achieve a goal. They become leaders due to internal and external conditions, rather than their own abilities. Japanese society has been basically male-dominated though the ratio of women leaders has increased recently. Higher education and development of academic societies in nursing have been very successful during the last two decades and nursing is one of the most trusted professions in Japan. However, some Japanese people still think a nurse is just an assistant to doctors. The purpose of this paper is to clarify features of women’s leadership in Japan from the nursing point of view. In Japanese culture, leaders need to possess human resource leadership as an indispensable element, while good leaders may have advantages in all four frames of leadership including structural, human resource, political, and symbolic frames. Japanese organizations are also supported by excellent followership which might be influenced by the structure of Japanese society which is called “the vertical society” where leaders are fostered from among followers. What is important in Japanese leadership is to have a vision that leadership leads to the happiness of all people in a shareable form.
Model to Simulate the Contribution of Fiber Reinforcement for the Punching Resistance of RC Slabs

AbstractIn this paper analytical formulations are developed for predicting the punching resistance of flat slabs of steel fiber–reinforced concrete (SFRC) flexurally reinforced with steel bars. By performing statistical analysis with a database that collects experimental results on the characterization of the postcracking behavior of SFRC, equations are determined for evaluating the residual flexural tensile strength parameters (fRi) from fundamental data that characterize steel fibers. The fRi strength parameters proposed by CEB-FIP 2010 were used for the definition of the stress-crack width law (σ-w) that simulates the fiber-reinforcement mechanisms in cement-based materials. The second part of the paper describes an analytical formulation based on the concepts proposed by Muttoni and Ruiz, where the σ-w law is conveniently integrated for simulation of the contribution of steel fibers for the punching resistance of SFRC slabs. By using a database composed of 154 punching tests with SFRC slabs, the good .
The UK stock market’s relationship with US and European stock markets: Is the UK stock market snuggling-up to the US - or to Europe?

Using 27 years of data this paper considers short-run, bi-lateral, and long-run, linkages between the US, UK and nine European equity markets. Using time-varying parameter and multivariate cointegration modelling techniques, we show that since October 1992, UK stock market returns have become increasingly sensitive to perturbations in the US market relative to those in European markets. We also report evidence to suggest that over the long term stock markets are perfectly correlated and although deviations from this long-term trend do occur, with the possible exception of the US and UK market, they are rarely significant. For the US and UK markets, we found that the 1990s has tended to display a few small, but significant deviations, from the permanent component of stock prices. Overall, however, any gains from international diversification would tend to be short-lived.
Isolation and analysis of microsatellites in the genome of turbot ( Scophthalmus maximus L.)

A microsatellite enrichment libraries construction colony hybridization strategy was used for largescale isolation of microsatellites from the whole genome of the turbot ( Scophthalmus maximus L.). Using 14 different probes, paired-end sequencing of 952 clones resulted in 753 positive and individual clones. Using Vector NTI Suite 8.0 and tandem repeats finder software, 1004 tandem repeat sequences were found, including 831 microsatellites and 173 minisatellites, which accounted for 82.77 and 17.23% of the total repeat sequences, respectively. From the microsatellites, 158 polymorphic microsatellite markers were developed. A detailed analysis of the different nucleotide units across the whole genome of turbot was also presented, the dinucleotide unit was the dominant repeat unit among the six repeat unit types (as represented by number of repeats and the repeat unit cumulative length), while the pentanucleotide type was the most frequently found. The AGG (126.11) motif was the most variable repeat unit type in this research with a coefficient of variation value of 126.11. In this study, a negative correlation between the length of repeat units and the average copy number was detected ( r = -0.5, P = 0.072).
Rituximab-Based Therapy in Newly Diagnosed Diffuse Large B-Cell Lymphoma Patients: Individualized Risk-Adapted Therapy Approach Using Molecular Subtypes

Rituximab (R) with cyclophosphamide, doxorubicin, vincristine and prednisone (CHOP) is the current standard of care as first-line treatment for diffuse large B-cell lymphoma (DLBCL), the most common lymphoma subtype. Patients who fail R-CHOP have a poor outcome with relapse or refractory disease resulting in fatality in majority of patients. This review focuses on novel therapies which are currently being assessed as first-line treatment in combination with R-CHOP in patients with DLBCL. Targeted drug development is a possibility with recent developments like gene expression profiling, RNA interference screening, DNA sequencing, identification of new biomarkers and signaling pathways. Newer drugs such as bortezomib, lenalidomide, and ibrutinib are being investigated as first-line therapy in combination with R-CHOP (XR-CHOP) in the activated B-cell (ABC) subtype of DLBCL. Additionally, inhibitors of BCL6, EZH2, and PI3K/Akt/mTOR are being considered for treatment of germinal center B-cell (GCB) subtype of DLBCL in patients with probable survival of less than 5 years. Double- or triple-hit lymphomas and double-expressor lymphomas also have poor prognosis and research to identify effective first-line therapy in these patients remains an unmet need. Presently, individualized approach that includes effective therapeutic combinations with acceptable safety profiles for use in routine practice, especially in patients likely to have poor outcomes such as relapsed/refractory DLBCL remains a distant possibility. Current evidence shows that untreated high risk patients do not have the greater benefit with use of newer drugs compared with R-CHOP. Therefore, R-CHOP remains the first-line treatment for newly diagnosed DLBCL patients.
