Speciation of Soil Phosphorus Assessed by XANES Spectroscopy at Different Spatial Scales
Authors: Hesterberg Dean , McNulty Ian , Thieme Juergen 
Published: July 2017

Precise management of soil phosphorus (P) to meet competing demands of agriculture and environmental protection can benefit from more comprehensive characterization of P speciation in soils. Our objectives were to provide spatial context for spectroscopic analyses of soil P speciation in relation to molecular‐scale species and landscape‐scale management of P, and to compare soil P‐species diversity from spectroscopic measurements at submicron and millimeter scales. The spatial range of ∼26 orders of magnitude between atomic and field scales presents a challenge to upscaling and downscaling information from spectroscopic analyses of soils. Scanning fluorescence X‐ray microscopy images of a 50‐μm × 45‐μm area of an organic soil sample showed heterogeneous distributions of P, Al, and Si. Microscale X‐ray absorption near edge structure (μ‐XANES) spectra collected at the P K‐edge from 12 spots on the soil sample exhibited diverse features that indicated variations in highly localized P speciation. Linear combination fitting analysis of the μ‐XANES spectra included various proportions of three standards that appeared in fits for most spots and five standards that appeared in fits for one spot each. The fit to a bulk‐soil spectrum was dominated by two of the common standards in the μ‐XANES fits, and a fit to the sum of μ‐XANES spectra included four of the standards. These results illustrate a gain in P species sensitivity from spatially resolved XANES analysis. Integrating spectroscopic analyses from multiple scales determines soil P species diversity and will ultimately help connect speciation to the chemical reactivity and mobility of P in soils.Core Ideas
Diverse molecular‐scale species of phosphorus occur in a soil.
XANES analysis at different scales connects speciation across scales.
Microscale XANES spectroscopy analysis improves detection of minor P species.
Bulk‐sample XANES spectroscopy analyzes major P species in a representative volume.
Long‐term Effects of Organic Waste Fertilizers on Soil Structure, Tracer Transport, and Leaching of Colloids
Authors: Lekfeldt Jonas Duus Stevens , Kjaergaard Charlotte , Magid Jakob 
Published: July 2017

Organic waste fertilizers have previously been observed to significantly affect soil organic carbon (SOC) content and soil structure. However, the effect of organic waste fertilizers on colloid dispersibility and leaching of colloids from topsoil has not yet been studied extensively. We investigated how the repeated application of different types of agricultural (liquid cattle slurry and solid cattle manure) and urban waste fertilizers (sewage sludge and composted organic household waste) affected soil physical properties, colloid dispersion from aggregates, tracer transport, and colloid leaching from intact soil cores. Total porosity was positively correlated with SOC content. Yearly applications of sewage sludge increased absolute microporosity (pores <30 μm) and decreased relative macroporosity (pores >30 μm) compared with the unfertilized control, whereas organic household waste compost fertilization increased both total porosity and the absolute porosity in all pore size classes (though not significant for 100–600 μm). Treatments receiving large amounts of organic fertilizers exhibited significantly lower levels of dispersible colloids compared with an unfertilized control and a treatment that had received moderate applications of cattle slurry. The content of water‐dispersible colloids could not be explained by a single factor, but differences in SOC content, electrical conductivity, and sodium adsorption ratio were important factors. Moreover, we found that the fertilizer treatments did not significantly affect the solute transport properties of the topsoil. Finally, we found that the leaching of soil colloids was significantly decreased in treatments that had received large amounts of organic waste fertilizers, and we ascribe this primarily to treatment‐induced differences in effluent electrical conductivity during leaching.Core Ideas
Sewage sludge application may lead to an increase in the percentage of small pores.
Organic waste compost application leads to a general increase in porosity.
Large amounts of organic waste fertilizers lead to decreased leaching of colloids.
Soil water EC may be a stronger determinant of colloid leaching than organic C.

Published: July 2017

Most of the document summary are arranged extractive by taking important sentences from the document. Extractive based summarization often not consider the connection sentence. A good sentence ordering should aware about rhetorical relations such as cause-effect relation, topical relevancy and chronological sequence which exist between the sentences. Based on this problem, we propose a new method for sentence ordering in multi document summarization using cluster correlation and probability for English documents. Sentences of multi-documents are grouped based on similarity into clusters. Sentence extracted from each cluster to be a summary that will be listed based on cluster correlation and probability. User evaluation showed that the summary result of proposed method easier to understanding than the previous method. The result of ROUGE method also shows increase on sentence arrangement compared to previous method.
Water quality model with axial dispersion solved by Eulerian-Lagrangian operator-splitting method in water distribution system
Authors: Chen Guoqiang , Long Tianyu , Bai Yun 
Published: July 2017

Abstract
This study explores the effects of water quality simulation results by embedding axial dispersion into the classical advective-reactive model in a water distribution system. The Eulerian-Lagrangian operator-splitting method is employed to solve the model with axial dispersion. Satisfactory results were obtained after the numerical solution was tested against the analytical and other numerical solutions. The water quality simulation results without the reaction item show that when water velocity is low (or Peclet numbers are small), dispersion is dominant and significantly affects the numerical simulation results. The contaminant concentration at downstream node gradually increased with time along the upstream pipelines from the source, which is particularly reflected in the terminal. The simulation results show that the biomass concentration may demonstrate synthetic effects of axial dispersion and reaction, i.e. mutual promotion, given the multicomponent (substrate, residual chlorine, and microbial biomass) reaction-transport processes. It is particularly reflected in the low flow velocity.

Preliminares para la comprensión del concepto logos en el Comentario a Juan de Orígenes.
Authors: Soler Fernando 
Published: July 2017

This paper deals with some essential considerations to understand the concept of ?ó???, present in Origen’s Commentary on John. These considerations begin with a brief approximation to the philosophical environment in which the Commentary is inserted, leading us to try to answer the question of how far gospels are a source for Origen’s thought. Next, an etymological approximation to the term ?ó??? will be made to describe its richness and, then, its use will be shown in both the Bible and some representatives of the Alexandrian Patristic tradition previous to Origen. Finally, we will briefly stop in Philo who, although being previous to Patristic authors, has a key influence on Origenian thought.

Em tempos de era digital, a escola e a universidade precisam cada vez mais repensar em incorporar as tecnologias digitais da informação e comunicação (TDIC) às necessidades atuais do aluno. Daí a importância das TDIC se tornarem elos no ensino-aprendizagem, com a escola e a universidade repensando seus nichos na atualidade, ou seja, professores mudando procedimentos de ensino; currículos menos informativos e mais e flexíveis; aulas menos expositivas e mais desafiadoras; integração de projetos para compreender o quê e o porquê se aprende; alunos como centro da aprendizagem; tecnologias como aliadas e não à margem do processo educacional; entre outros fatores. Nessa direção, a escola e a universidade deveriam ser vistas como um espaço para os alunos aprenderem de forma contínua com o uso das TDIC. Pensando nessas questões é que abrimos a edição do volume deste ano com um número temático dedicado ao uso das TDIC e ao ensino-aprendizagem de línguas. O objetivo é apresentar propostas pedagógicas relacionadas a materiais educacionais digitais, no intuito de trazer contribuições de experiências e de investigação para a área de ensino-aprendizagem de línguas em contextos digitais.

Published: July 2017

This paper proposes a simple direct power control using space vector modulation (DPC-SVM) for three-phase three level neutral point clamped (3L-NPC) PWM converter connecting a wind turbine generator with grid. The active and reactive power are used as the control variables instead of the currents applied in conventional control method. Moreover, grid voltage sensors are replaced by a virtual flux (VF) estimator. The theoretical principle of this method as well as the synthesis of the active and reactive power controllers are discussed. It is shown that the proposed method exhibits several features as: simple and robust algorithm as well as simple tuning procedure of PI power controllers. Furthermore the paper presents a LCL-filter design, which fulfils IEEE-SCR 20-50 recommendation. Simulation results have proven an excellent performance and verified the validity of the proposed system.

Published: July 2017

A current sensor based in the Rogowski coil is an innovative measuring system that gives advantages with respect to conventional measuring systems based in current transformers with magnetic core [1], [2].and [3]. Their main advantages are: the linearity, the span and the bandwidth. Different kinds of manufacturing allow to obtain an important variety of Rogowski coils with different properties. One way of manufacturing is using the same method as for producing printed circuit boards, so by this way is possible to produce coils very similar and with a high precision. The authors are working in current measurement with Rogowski coils or Hall effect sensors and in particular in the realization of good and accurate coils [4] and [5].In this work, the influence of external currents to the coil in the measured current by the coil has been evaluated.
