Rapidly Interpreting UV-optical Light Curve Properties Using a “Simple” Modeling Approach
Authors: De La Rosa Janie , Roming Pete , Fryer Chris
Published: November 2017

Core-collapse supernovae (CCSNe) have very distinct observational properties that depend on the composition of the progenitor star, the dynamics of the explosion mechanism, and the surrounding stellar wind environment. In recent years, due to the uncertainty behind the type of massive star that evolves into different types of core-collapse events, there has been an increase in core-collapse supernova surveys aiding the advancement of numerical supernova simulations that explore the properties of the star before the explosion. Observationally, the unpredictable nature of these events makes it difficult to identify the type of star from which the CCSNe subtype evolves, but the issue from a theoretical standpoint relies on a gap in our current understanding of the explosion mechanism. The general light curve properties of CCSNe (rise, peak, and decay) by subtype are diverse, but appear to be homogeneous within each subtype, with the exception of Type IIn. Simplified SN models can be processed quickly in order to explore the properties of the progenitor star along with the explosion mechanism and circumstellar medium. Here, we present a suite of SN light curve models presented using a 1-temperature, homologous outflow light curve code. The SN explosion is modeled from shock breakout through the ultimate uncovering of the nickel core. We are able to rapidly explore the diversity of the SN light curves by studying the effects of various explosion and progenitor star parameters, including ejecta mass, explosion energy, shock temperature, and stellar radii using this “simple” calculation technique. Furthermore, we compare UV and optical modeled light curves to Swift UVOT IIn observations to identify the general initial conditions that enable the difference between SN 2009ip and SN 2011ht light curve properties. Our results indicate that the peak light curve is dominated by the shock temperature and explosion energy, whereas the shape depends on the mass of the ejecta and the explosion energy. Based on this modeling approach, the comparison SN light curves are a product of processes occurring after shock breakout, but before 56Ni decay. Therefore, the energy from nickel decay does not play a major role in the light curves of these explosions. In general, the diversity between SN 2009ip and SN 2011ht can be explained by the differences in the outer ejecta mass and the explosion energy.

Published: November 2017

We obtain scatter-broadened images of the Crab Nebula at 80 MHz as it transits through the inner solar wind in 2017 and 2016 June. These images are anisotropic, with the major axis oriented perpendicular to the radially outward coronal magnetic field. Using these data, we deduce that the density modulation index (

) caused by turbulent density fluctuations in the solar wind ranges from

to

between 9 and 20 R
⊙. We also find that the heating rate of solar wind protons at these distances ranges from

to

. On two occasions, the line of sight intercepted a coronal streamer. We find that the presence of the streamer approximately doubles the thickness of the scattering screen.
Magnetic Pumping as a Source of Particle Heating and Power-law Distributions in the Solar Wind
Authors: Lichko E. , Egedal J. , Daughton W. , Kasper J.
Published: November 2017

Based on the rate of expansion of the solar wind, the plasma should cool rapidly as a function of distance to the Sun. Observations show this is not the case. In this work, a magnetic pumping model is developed as a possible explanation for the heating and the generation of power-law distribution functions observed in the solar wind plasma. Most previous studies in this area focus on the role that the dissipation of turbulent energy on microscopic kinetic scales plays in the overall heating of the plasma. However, with magnetic pumping, particles are energized by the largest-scale turbulent fluctuations, thus bypassing the energy cascade. In contrast to other models, we include the pressure anisotropy term, providing a channel for the large-scale fluctuations to heat the plasma directly. A complete set of coupled differential equations describing the evolution, and energization, of the distribution function are derived, as well as an approximate closed-form solution. Numerical simulations using the VPIC kinetic code are applied to verify the model’s analytical predictions. The results of the model for realistic solar wind scenario are computed, where thermal streaming of particles are important for generating a phase shift between the magnetic perturbations and the pressure anisotropy. In turn, averaged over a pump cycle, the phase shift permits mechanical work to be converted directly to heat in the plasma. The results of this scenario show that magnetic pumping may account for a significant portion of the solar wind energization.

Devenir soi-même sous l’exigence de justice devant autrui. Levinas, la justice pour autrui et la critique des théories de la justice sociale
Authors: Mardellat Patrick
Published: November 2017

La philosophie de Levinas pense la justice depuis l’événement d’autrui qui surgit et arrache le moi à son intériorité jouissant des nourritures, constituant une totalité économique. L’agent économique ne devient soi-même que par cette interpellation qui le soumet à une exigence de justice pour autrui. Qu’advient-il de l’économie lorsque la relation avec autrui est pensée avec la radicalité qui est celle de la philosophie de Levinas ? Et si l’absolutisation du Moi comme point de départ de la théorisation de l’économie conduit à l’injustice, voire même constitue la forme première de l’injustice, comment se conçoit alors la justice en posant l’antériorité d’autrui sur soi-même ? Quelles sont alors les limites des théories de la justice sociale sous cette dernière perspective ? La justice sociale avec ses institutions s’en trouve-t-elle définitivement condamnée ? Cet article se propose de répondre à ces questions et de discuter la pertinence des théories de la justice sous la perspective ouverte par la pensée de Levinas. En conclusion, la question de la possibilité de la justice économique est posée.

Authors: Lucherini Franco , Rapaccini Mario
Published: November 2017

Purpose: This paper describes the use of simulation and case-study research to assess flexibility gains induced by the adoption of three Lean Manufacturing practices.Design/methodology/approach: We gather useful material and information about the manufacturing process of a selected Small-Medium Enterprise by adopting a case-research approach. The Value Stream Mapping is the method used for visualizing flows of products and information along the production system. Starting from the current arrangement of the company, computer simulation is used to assess the benefits arising from Cellular Manufacturing, Just-in-Time Delivery by Suppliers, and Single Minute Exchange of Dies.Findings: To investigate the flexibility improvements coming from the introduction of Lean Manufacturing, we present a simulation model of the described company on which we performed our analysis. We quantify the flexibility of different configurations according to the new 5-step approach in order to segregate the contribution of different lean techniques.Originality/value: We extend the combined use of Case Research and Computer Simulation to the research on Manufacturing Flexibility within Small-Medium Enterprises. We enhance the knowledge on this under investigated context collecting quantitative field data. Moreover, building on the factorial Design of Experiment, we introduce a new 5-step method to appraise the cost benefit ratio of lean techniques for flexibility. The managerial implication of this research is mostly related to the provision of a supporting method for the decision making process propaedeutic to Lean Manufacturing introduction.

Authors: Hanawalt Edward , Rouse William
Published: November 2017

Purpose: Evaluating country manufacturing location attractiveness on various performance measures deepens the analysis and provides a more informed basis for manufacturing site selection versus reliance on labor rates alone. A short list of countries can be used to drive regional considerations for site-specific selection within a country.Design/methodology/approach: The two-step multi attribute decision model contains an initial filter layer to require minimum values for low weighted attributes and provides a rank order utility score for twenty three countries studied. The model contains 11 key explanatory variables with Labor Rate, Material Cost, and Logistics making up the top 3 attributes and representing 54% percent of the model weights.Findings: We propose a multi attribute decision framework for strategically assessing the attractiveness of a country as a location for manufacturing automobiles.Research limitations/implications: Consideration of country level wage variation, specific tariffs, and other economic incentives provides a secondary analysis after the initial list of candidate countries is defined.Practical implications: The results of our modeling shows China, India, and Mexico are currently the top ranked countries for manufacturing attractiveness. These three markets hold the highest utility scores throughout sensitivity analysis on the labor rate attribute weight rating, highlighting the strength and potential of manufacturing in China, India, and Mexico.Originality/value: Combining MAUT with regression analysis to simplify model to core factors then using a “must have” layer to handle extreme impacts of low weight factors and allowing for ease of repeatability.

Preparing adult learners to bring their expertise to improve new processes requires learner activation. Once learners are fully activated, they can bring their unique perspective to apply knowledge and facilitate change. For nurses, who are closest to the patient, activating the nursing perspective to continue to improve on the changes that will continue to pervade health care is critical. This is the role of the professional development educator.

Un ensayo experimental sobre la ecofisiología del poliqueto intersticial Polygordius eschaturus (Annelida: Polygordiidae)
Authors: Pereira de Souza-Santos Lilia
Published: November 2017

El presente estudio se centra en el análisis de la tolerancia a los cambios de salinidad y temperatura, así como las respuestas a la intensidad de la luz, la gravedad y la tensión de oxígeno de individuos de Polygordius eschaturus recogidos en una playa reflectante con sedimentos arenosos. La exposición a salinidades de 10, 20 y 50 psu durante 192 h a 10°C, causó la muerte de casi todos los individuos, mientras que los expuestos a 30 y 40 psu se movían lentamente. A 20-30°C todos los individuos sometidos a 10 psu murieron, mientras que a 50 psu algunos se comportaron anormalmente, entre 20 y 40 psu todos se comportaron con normalidad y a 40°C todos murieron al cabo de 24 h. El modelo de migración observado en nuestros experimentos se explica por la existencia de conductas fotonegativas y geopositivas, pero también por una respuesta positiva a gradientes positivos de tensión de oxígeno. Estas pautas de comportamiento, junto con el carácter eurihalino y euritermo de la especie, coinciden con las características típicas de su hábitat, situado a entre 10 a 20 cm de profundidad en arenas gruesas por encima de la zona de salpicaduras. En la zona intermareal de la playa tropical donde se recogieron los ejemplares estudiados, un comportamiento combinado que genere una atracción por las capas subsuperficiales, más oscuras aunque aún bien oxigenadas, supone una exitosa adaptación ya que resulta en una adecuada protección frente los fuertes cambios de temperatura y salinidad de las capas más superficiales.

Authors: Chohan Afaq Hyder , Mohd Affandi Haryanti , Awad Jihad , Che-Ani Adi Irfan
Published: November 2017

The variety of planning and design solutions occasionally turns into an underpinning factor for the defects and maintenance issues in built forms. Defects and maintenance that emerges from deficient design indicate that the design has not been conceded in the perception of quality. Reviewing the nature of deficient designs and resulting maintenance problems in various types of built forms revealed that housing sector is most effective of this phenomenon. The reason could be set as; housing planning, design, and construction are a most practiced activity to address the living needs of the ever-growing world population. This research considered that design quality of housing is severely affected in developing countries. In this regard housing standards and bylaws plays a minor role to ensure the housing quality in developing regions. However, it is notable that, in developing regions, the majority of populations have easy access to mobile communication technology. Therefore, it is possible to use mobile technology to educate the people about quality issues of housing and to help them to evaluate the quality of proposed or existing housing.   At present, the use of mobile technology has not only heightened the need for IT knowledge but also extend the capabilities of many designers/architects and builders. Hence, there is a niche to develop an integrated hub that could appraise the function of each professional involved in housing processes. This research has established a criterion that, the mobile technology can help common people to understand the quality of house/housing and to ascertain it. The results of the research have surfaced a model of mobile application that could be used later to prepare the real-time mobile application to work as a “design quality assessment tool.”

Learning a second language is not an easy task. Learners need to have enough support in terms of learning materials in order to be successful in mastering the language. One of the common problems faced by the second language learners is the difficulty to find the learning materials to develop their speaking skills. This is in contrast to the materials for the development of other language skills, such as reading and writing which are easily accessible from bookstores and resource centers. This paper introduces an innovative application named Virtual Speaking Buddy (VirSbud) which is specially designed to help second language learners develop their speaking skills. It is hoped that this application will be a useful resource to improve the standard of speaking skills among English language learners.

Published: November 2017

Historische stedelijke pakhuizen zijn opmerkelijke structuren. Ondanks hun robuuste architectuur zijn ze nu echter kwetsbaar stedelijk erfgoed geworden en worden ze met sloop bedreigd. Lopend onderzoek aan de Vrije Universiteit Brussel richt zich op de ontwikkeling van kennis over de architectuur, de werking en de bouw van pakhuizen in Antwerpen, Brussel en Gent en hun integratie in het stedelijke weefsel, om zo hun behoud en een respectvolle herbestemming te steunen. Deze paper bevat de resultaten van een grondig archiefonderzoek en van de eerste plaatsbezoeken van de negentiende en twintigste-eeuwse pakhuizen in het historische centrum van Brussel, en meer bepaald in de eerste industriële zone rond de Zenne en de dokken. Tachtig afgebroken en nog bestaande stedelijke pakhuizen worden geanalyseerd door in de eerste plaats te focussen op de meest voorkomende opslaggoederen: hooi, hout, bier en textiel. Uit de analyse blijkt dat de vier goederen overeenstemmen met vier types pakhuizen die verschillen in hun architectuur, organisatie, bouw en integratie in het stedelijk weefsel.
An Insight Into the Scientific Datasets in Archaeological Research Through the Pottery Provenance Case
Authors: Kazakis Nikolaos A. , Tsirliganis Nestor C.
Published: November 2017

Recent trends in archaeological research dictate the incorporation of various analytical methods for dating, chemical/mineralogical characterization, morphological description, etc. of various excavation findings and landscapes to support and corroborate the archaeologists' observations. Each method, when used individually, provides a different feedback, but once single studies are combined, the information produced can significantly contribute to the solution of the archaeological puzzle. Thus, numerous scientific data and metadata are produced creating large and complex scientific datasets. The use of common terminology and definitions to describe these data along with the establishment of a formal standardized structure that any cultural heritage information could be mapped to would assure the credibility and durability of such scientific datasets. The present work provides an overview of the types and formats of the scientific data and metadata produced in the archaeological research through the detailed presentation of the common practices used in pottery provenance studies.

Authors: Yoon Young Ok , Kim Nam Seok , Kim Bong Hwan , Kim Shae K.
Published: November 2017

Interface reaction between SKD61 and three Al melts at 973 K was investigated in this study. In pure Al and A380 alloy, soldering occurred on the samples. Pure Al showed two separated soldering areas consisting of Fe-Al based intermetallic phases, mainly FeAl3. A380 alloy indicated the expanded soldering area consisting of Al3Fe and two AlFeSi based intermetallic phases. Al-10mass%Mg alloy showed the absence of soldering, but a formation of a few Fe-Al intermetallic phases. This would be attributed to weakened interaction between Fe and Al caused by Mg enrichment. Microstructures near soldering of pure Al and A380 also showed the precipitations considered as Al3Fe and AlFeSi intermetallic compounds, respectively. However, in Al-10mass%Mg alloy, there is only intermetallic compound including Mg, V and Ca without Al3Fe.

In this article new experimental evidences of anomalous grain boundary diffusion (GBD) of Fe and Co in Cu were describe. To demonstrate that the brief describing of results of grain boundary diffusion in Cu with following formulation of rules which can be established on the base of the analysis of the results is presented. Experimental results which are described here concern the attempt to change the effect negative segregation by microalloying by sulfur which did not change the situation and the diffusion through foil which allowed to demonstrate the absence of accelerated GB diffusion without specific sample preparation. It is shown that GBs do not give the additional effect to the flux of Fe and Co through the foil. The extended model of surface tension gradient as an additional driving force is described.

Published: November 2017

Among many Enhanced Oil Recovery (EOR) methods, chemical flooding for wettability alteration of carbonate oil-wet rock is one of the most noticeable methods amid researchers. However, several crucial aspects concerning wettability alteration are still unknown and unanswered to date. Understanding the ionic composition of brine is a very important subject to which numerous studies are being dedicated, with the objective of determining the role of brine and its composition on wettability alteration, particularly its effects on EOR. The objectives of this research work is the investigation of the effects of different brine ions (Ca2+, Mg2+ and SO42-) on wettability alteration of oil-wet carbonate rocks while using cationic surfactant flooding Dodecyl Trimethyl Ammonium Bromide (DTAB). Results showed that the presence of SO42- is crucial and can improve DTAB efficiency. Contact angle maximum change is 62o to 19o with concentration of Na2SO4 equal to 6 g/l.

Authors: Elshahed Mostafa A. , Dawod Mahmoud , Osman Zeinab H.
Published: November 2017

Integrating Distributed Generation (DG) units into distribution systems can have an impact on the voltage profile, power flow, power losses, and voltage stability. In this paper, a new methodology for DG location and sizing are developed to minimize system losses and maximize voltage stability index (VSI). A proper allocation of DG has to be determined using the fuzzy ranking method to verify best compromised solutions and achieve maximum benefits. Synchronous machines are utilized and its power factor is optimally determined via genetic optimization to inject reactive power to decrease system losses and improve voltage profile and VSI. The Augmented Lagrangian Genetic Algorithm with nonlinear mixed-integer variables and Non-dominated Sorting Genetic Algorithm have been implemented to solve both single/multi-objective function optimization problems. For proposed methodology effectiveness verification, it is tested on 33-bus and 69-bus radial distribution systems then compared with previous works.

Published: November 2017

Today, only a very small portion of plastic waste is recycled, while huge quantities remain untreated and are becoming increasingly worrying. The search for other alternatives is still an urgent necessity so that these wastes can be reduced to the maximum; their valorization may be the best solution. This study concerns a new technique for the valorization of polyethylene terephthalate (PET) plastic bottle wastes, in order to design a composite material, i.e. siliceous sand-PET, which then gives a Waste Plastic Lightweight Aggregate “WPLA”. Our hope is to provide solutions to specific and general applications in the field of construction. Some observations are noted on the effects of this composite on destructive and non-destructive testing, such as the physical properties and mechanical behaviors of an industrial composite screed, by substituting 0, 25, 50, 75 and 100% by weight of natural aggregate by this composite. Scanning electron microscope (SEM), FT-IR and X-ray diffraction analyses were used to better understand the cement hydration products of the composite mortars. Some possible uses of this screed, or even of the composite itself, can subsequently be recommended. Encouraging results were obtained regarding the usage of this composite aggregate as an eco-material in the field of construction for sustainable development. In addition, it provides environmental-friendly and cost-effective solutions in using recycled materials for concrete construction applications.

Published: November 2017

The knowledge of potential tunneling hazards plays an important role in the selection of excavation method and designing a support system for underground openings. Failure of a rock mass will occur when the in-situ stress exceeds the in-situ rock mass strength. Nowadays, Ethiopia is trying to construct a newly planned railway route to connect the country’s development centers and link with ports of neighboring countries. However, this newly planned railway route will pass through the heart of highly fragile mountainous terrains and earthquake prone regions. Therefore, a study of potential Hazards for the new railway tunnel (T-07) at a particular critical section has been done by using two commercially available programs (Rocsupport and Phase2). The final Tunnel Convergence of the railway tunnel was found to be 1.11% (using Rocsupport) and 1.59% (using Phase2 finite element analysis).This discrepancy is attributed to the assumptions made in the Rocsupport software. Based on the results, a minor squeezing problem will be expected in this particular rail way tunnel section. Finally, a safe and economical reinforced concrete support type was recommended based upon the numerical analysis.

Published: November 2017

The optimal power flow (OPF) problem is a very complicated task in power systems. OPF problem has a set of equality and inequality constraints. This paper looks at a chaotic cuckoo search (CCS) algorithm for solving non-convex OPF problem. The proposed CCS is a bio-inspired optimization calculation that is inspired by the behaviour of cuckoos people in nature. The chaotic guide is a variation of qualities combined with CS. A sinusoidal chaotic is integrated with CS algorithm and tested on standard IEEE 30-bus test system to the point of improving its global speed of convergence and enhancing its performance. The elitism scheme is also serves to save the best cuckoo during amid the procedure when updating the cuckoo. The results show clearly the superiority of CCS in searching for the best function values results when compared with well-known metaheuristic search algorithms.
Metallographic Analysis of Filiform Corrosion
Authors: Hrabčáková Lucia , Mašlejová Alicia
Published: November 2017

The surface line type defects on the can twist-off lids from lacquered tinplate material have been analyzed. The analyzed defects manifested themselves like the lines bulged above the surrounding surface. They were aligned roughly perpendicular to the lid circumference; they were mostly arranged on the lower part of lid circumference edge. The defects surface was fully covered by lacquer layer. After lacquer layer removal it was visible in the defective area that tin layer was damaged on some defect areas. The defect presented itself like filiform corrosion which occurred in conditions slightly above room temperature and high humidity under the originally continuous covering layer. According to the findings, corrosion occurred on the hidden sheet cut edges and then propagated first perpendicular to the circumference into the sheet. Then sometimes its direction changed into the sheet rolling direction along the lines with less but still suitable tin layer thickness. This defect can be controlled by special protecting of lid cut edge against corrosion or decreasing of the temperature and the humidity conditions in the stores.
Toxoplasma gondii Inactivates Human Plasmacytoid Dendritic Cells by Functional Mimicry of IL-10

Published: November 2017

Plasmacytoid dendritic cells (pDCs) are the major producers of IFN-α, an antiviral cytokine involved in immunomodulation and control of HIV type 1 replication, whereas Toxoplasma gondii is a life-threatening opportunistic infection in AIDS patients. During infection with HIV type 1, human pDCs decrease in circulation and remaining pDC produce lower amounts of IFN-α in response to viral stimulation. In this study, we investigated the impact of coinfection with T. gondii on the innate virus-directed responses of human pDCs. Using intracellular flow cytometry and fluorescence microscopy, we determined that T. gondii invaded but did not induce IFN-α or TNF-α in human pDC. However, T. gondii inhibited IFN-α and TNF-α produced in response to HSV and HIV, thus functionally inactivating pDC. IFN-α production was inhibited only in cells infected by T. gondii, which inhibited neither uptake of GFP-HSV nor localization of TLR9 in CD71+ endosomes, directing us to investigate downstream events. Using imaging flow cytometry, we found that both T. gondii and IL-10 inhibited virus-induced nuclear translocation, but not phosphorylation, of IFN response factor 7. Blockade of IFN response factor 7 nuclear translocation and inhibition of the IFN-α response was partially reversed by a deficiency in the T. gondii–derived ROP16 kinase, known to directly phosphorylate STAT3, a critical mediator of IL-10’s anti-inflammatory effects. Taken together, our results indicate that T. gondii suppresses pDC activation by mimicking IL-10’s regulatory effects through an ROP16 kinase-dependent mechanism. Our findings further imply a convergent mechanism of inhibition of TLR signaling by T. gondii and IL-10 and suggest potential negative consequences of HIV/T. gondii coinfection.
Fish farming as an innovative strategy for promoting food security in drought risk regions of Zimbabwe
Authors: Shava Elvin , Gunhidzirai Constance
Published: November 2017

This article examines the implementation of fish farming as an innovative and economic strategy for promoting food security and dietary diversities among vulnerable households in drought risk areas of Zimbabwe. The declining climatic conditions and lack of economic opportunities in Mwenezi district of Zimbabwe attracted the attention of three nongovernmental organisations (NGOs) to implement fish farming as an innovative mechanism to stimulate food security and generate employment in the district. The article used a qualitative research approach that includes semi-structured interviews and secondary data. The purposive sampling technique was adopted to interview participants in Mwenezi district who were involved in fish farming to assess and explore the experiences and benefits they derive from such development projects. Results for the article revealed that fish farming was well embraced by local communities as it led to improvements in food security, household income and employment regeneration. The local government including traditional leadership (Chiefs and Headmen’s) supported the NGO activities as they benefited local communities. The article concludes that although fish farming was instrumental in regenerating employment, some participants still fail to participate because of laziness and desire to maintain dependency syndrome. The article recommends the NGOs to launch awareness campaigns in rural communities and increase networking with the donor community which is fundamental in attracting sustainable funding. The government can also promote fish farming in vulnerable rural communities by providing funding and capacity building programmes.

Background: Managers’ organisational decisions and subsequent actions flow from their understanding of the business environment in which they operate. This study sought to understand how managers in various organisations identify, evaluate and use information for effective current and future decision-making.Objectives: The study focused on the types of information needed by managers for decision-making, the methods used to identify and acquire the information and the sources of information consulted, their satisfaction with the information used and their decision-making behaviours.Methods: The study employed descriptive study design. Simple random sampling was used. A pre-tested self-administered questionnaire was used to gather information from 219 managers, randomly selected from the registers of the Ibadan, Abeokuta and Lagos chapters of Nigerian Institute of Management.Results: Results indicated that the types of information considered very important for decision-making included industry information followed by government policies and economic development/forecasts.Conclusion: Investigation revealed the extent of information identification, information evaluation and information utilisation individually predict the perceived effectiveness of decision-making by the managers. Nevertheless, information evaluation was found to have greater predictive relationship with perceived effectiveness of decision-making than information use and information identification.
Called and sent to make a difference: Radical missionality
Authors: Nel Malan
Published: November 2017

The concept ‘missional’ is well established within the so-called missional conversation. It is however often ‘questioned’ by scholars and pastors for different reasons. Sometimes it is almost dissected from the rest of theology, especially systematic theology. Recent developments in this field are given an account of in this article. The main purpose of the article is not to argue a case for the concept again. The purpose is to focus on whether theology and ministry in any way understand the radical implications if and when we are missional in being and doing. My assumption within the field of research on rediscovering discipleship in the development of missional congregations is that none of us have thought through how radical missionality is, especially over and against a ‘volkskirchliche’ understanding and practice of church. The article will also touch on some radical changes in philosophy of ministry and doing ministry within a missional paradigm.Intradisciplinary and/or interdisciplinary implications: The article focuses mainly on Practical Theology and specifically Congregational Development (‘Missionarische Gemeindeaufbau’). This field stands in a direct relationship with Missiology. The article contributes to a growing understanding of the radical nature of missional thinking and practice in congregational life and ministry.

Os fungos passaram a receber maior atenção como contaminantes de água potável, devido algumas doenças estarem relacionadas a esses microrganismos e ao abastecimento inadequado, principalmente em populações ribeirinhas. Este trabalho verificou a presença de fungos na água de consumo da comunidade ribeirinha, Lago do Limão, Iranduba - AM, e avaliou o perfil de patogenicidade dos fungos isolados. As espécies fúngicas isoladas foram identificadas fenotipicamente e geneticamente. A avaliação dos fungos, quanto ao seu potencial de patogenicidade, incluiu: Crescimento a 37°C, Produção de Ureases e Proteases. Como resultados, foram isoladas 101 culturas de diferentes gêneros da subdivisão Deuteromycotina. Os gêneros isolados de maior frequência foram Aspergillus spp (41,6%), Penicillium spp (19,8%) e Trichoderma spp. (27,7%). Quanto aos parâmetros de patogenicidade, verificou-se que 95% das amostras apresentaram positividade quando incubadas a 37ºC; 66,3% em meio Ágar Christensen e 58,4% no teste de Proteases. Há escassez de trabalhos que abordam a patogenicidade dos fungos presentes na água, principalmente, em água consumida pelas comunidades ribeirinhas. Espera-se que os resultados deste trabalho possam subsidiar a legislação brasileira estabelecer limites de fungos presentes em água potável.
Stability of an anaerobic single reactor filled with dolomitic limestone with increased organic load of sugarcane
Authors: Döll Maria Magdalena Ribas , Sousa Larissa Beatriz de
Published: November 2017

The anaerobic single-stage reactor was evaluated to treat vinasse and to evaluate its stability. This bench reactor was filled with dolomitic limestone with a horizontal plug flow to simulate a drainage channel. The experiment lasted 129 days while the reactor was submitted to different applied organic concentrations (chronologically applied: 3.0; 5.0; 12.0; 9.0 and 7.5 g L-1 as COD, chemical oxygen demand). COD removals were 50% and 9% with 3.0 and 7.5 g L-1, respectively. With 12.0 g L-1, reactor efficiency increased to 33%, with an abrupt drop to 3% on the 84th day. Therefore, in order to avoid reactor collapse, a remedial measure was necessary. The system remained in batch without feeding for 19 days (from the 85th to the 104th day) with 9.0 g L-1. Afterwards, it was observed that the performance of the system tended to stabilize, reaching 47% with 7.5 g L-1 in the 118th day. At the end of the experiment, the potassium content of the wastewater decreased from 800 mg L-1 to 594 mg L-1 (on an average 25%) and calcium and magnesium increased within the reactor liquor. The dissolution of the limestone inside the liquor reactor probably caused this result. After the treatment with limestone, the average pH value of the effluent increased from 4.9 to over 6.0 in all organic concentrations. It could be concluded that the reactor filled with dolomitic limestone in these operational conditions assured a low efficiency in COD removal, potassium reduction, increasing values of pH, alkalinity, calcium and magnesium. The instability was observed when there was increase in organic load to 12 g L-1 with subsequent recovery.

Remapping Capricornia: Xavier Herbert’s Cosmopolitan Imagination
Authors: Smith Ellen
Published: November 2017

Since its publication in 1938 critics have generally read Xavier Herbert’s Capricornia as a nationalist novel, even when its nationalism is seen to be structured by contradiction. But little attention has been given to the ways in which Herbert’s complex, multifarious and heteroglossic novel exceeds and challenges the very possibility of coherent national space and a coherent national story. This essay considers moments and spaces in Herbert’s novel where the national is displaced and unravelled. Drawing on Rebecca Walkowitz’s idea of cosmopolitan style and Suvendrini Perera’s work on Australia’s insular imagination I identify a critical cosmopolitanism that inheres in the novel’s geographical imagination and its literary form, particularly the narrative voice which retains a critical distance from the nationalist sensibility of various characters and plot lines, performing a detached and restless homelessness that I identify with the cosmopolitan. Ultimately I ask how the novel’s spatial and environmental imagination displaces its nationalist agenda, making space for a different kind of social imagination—one that does not confine itself to the terms of the nation or organise itself around a central figure for the nation.

Decrease in tropospheric O3 levels of the Northern Hemisphere observed by IASI

Published: November 2017

Abstract. In this study, we describe the recent changes in the tropospheric ozone (O3) columns (TOCs) measured by the Infrared Atmospheric Sounding Interferometer (IASI) onboard the Metop satellite during the first 9 years of the IASI operation (January 2008 to May 2017). Using appropriate multivariate regression methods, we discriminate significant linear trends from other sources of O3 variations captured by IASI. The geographical patterns of the adjusted O3 trends are provided and discussed on the global scale. Given the large contribution of the natural variability in comparison with that of the trend (25–85 % vs 15–50 %, respectively) to the total O3 variations, we estimate that additional years of IASI measurements are generally required to detect the estimated O3 trends with a high precision. Globally, additional 6 months to 6 years of measurements, depending on the regions and the seasons, are needed to detect a trend of  |5| DU/decade. An exception is interestingly found during summer in the mid-high latitudes of the North Hemisphere (N.H.; ~ 40° N–75° N) where the large absolute fitted trend values (~ |0.5| DU/yr on average) combined with the small model residuals (~ 10 %) allow the detection of a band-like pattern of significant negative trends. This finding supports the reported decrease in O3 precursor emissions in recent years, especially in Europe and US. The influence of continental pollution on that latitudinal band is further investigated and supported by the analysis of the O3–CO relationship (in terms of correlation coefficient, regression slope and covariance) that we found to be the strongest at the northern mid-latitudes in summer.
Characterizing the complexity of seismic signals at slow-moving clay-rich debris slides: The Super-Sauze (Southeastern France) and Pechgraben (Upper Austria) case studies

Published: November 2017

Abstract. Soil and debris slides are prone to rapid and dramatic reactivation. Deformation within the instability is accommodated by sliding, whereby weak seismic energies are released through material deformation. Thus, passive microseismic monitoring provides information that relate to the slope dynamics. In this study, passive seismic data acquired at Super-Sauze (Southeastern France) and Pechgraben (Upper Austria) slow-moving clay-rich debris slides (“clayey landslides”) are investigated. Observations are benchmarked to previous similar case studies to provide a comprehensive and homogenized typology of seismic signals at clayey landslides. A well knowledge of the various seismic signals potentially triggered by the slope deformation is crucial for the future development of automatic detection systems to be implemented in early-warning systems. Detected seismic events range from short duration (
