Structural and dielectric studies of Mg2+ substituted Ni–Zn ferrite
Authors: Vara Prasad B.B.V.S. , Rajesh Babu B. , Siva Ram Prasad M. 
Published: December 2015

AbstractPolycrystalline ferrites having the chemical formula Ni0.65−xZn0.35MgxFe2O4 (0 ⩽ x ⩽ 0.2) were prepared by solid state reaction route in steps of x = 0.04. The effect of incorporation of diamagnetic divalent magnesium at expense of nickel on the structural properties of these ferrites has been studied. The proposed cation distribution was derived from theoretical X-ray diffraction intensity calculations. These intensity calculations were done by varying the concentration of magnesium ions over two sites in the lattice. For a certain amount of magnesium concentration, the calculated and observed X-ray diffraction intensities were found to be in good agreement. Site occupancy of divalent diamagnetic magnesium was established from this cation distribution. The octahedral environment facilitates magnesium to enter the B-site at about 95 % and the remaining 5 % occupy tetrahedral sites (A-sites). The movements of cations between tetrahedral and octahedral sites as a result of magnesium substitution were discussed in the view of structural parameters, such as tetrahedral and octahedral bond lengths, cation-cation and cation-anion distances, bond angles and hopping lengths, which were calculated using experimental lattice constants and oxygen parameters. All structural parameters showed slight deviations from ideal values. Among all magnesium substituted samples, the ones with x = 0.12 exhibited insignificant variation in view of structural properties. Dielectric measurements were conducted at a standard frequency of 1 kHz. Large values of the recorded dielectric constants displayed typical characteristics of bulk ferrites. Both dielectric constant and loss values showed mixed variations, attributed to the loss of zinc ions during the sintering process.
El extranjero, un encuentro fallido de Camus y Visconti
Authors: Aíssa Carlos María Ramírez 
Published: December 2015

<p>Este ensayo –escrito en memoria del escritor francés al cumplirse cincuenta años de su muerte– aspira a ligar a través de la creación artística dos hombres fundamentales que, venidos al mundo con escasa diferencia de años, intervinieron en los conflictos de su tiempo, llevando esa participación hasta el mayor de los peligros, aunque desde tradiciones y circunstancias significativamente distintas. Unas y otras tuvieron mucha incidencia en la lectura y adaptación cinematográfica de una novela con la que Luchino Visconti se propuso sumergir el destino humano del antihéroe camusiano en el trasfondo político de la guerra de Argelia.</p>
Hacia una estética de las nuevas tecnologías como proyecto educativo
Authors: López Juan Sebastián López 
Published: December 2015

<p>Este artículo parte de la descripción de un cambio de época en curso, analizado en los niveles del orden social, la cultura, la comunicación y las tecnologías. De ahí se extraen una serie de retos a los que se enfrenta cualquier proyecto de educación contemporáneo. En este marco problémico, se examinarán algunos puntos fundamentales de la teoría estética de Theodor Adorno. Lo que se intenta proponer es una concepción de la estética asumida como mediación conceptual de la experiencia del sujeto con su entorno. Este será el primer paso para consolidar un proyecto educativo que resuelva uno de sus retos más urgentes: reducir la brecha entre el desarrollo tecnológico y sus correspondientes mediaciones culturales.</p>
El papel de las humanidades y las ciencias sociales desde la comprensión de la complejidad ambiental y la tradición espiritual oriental
Authors: Clavijo Ana Cecilia Vallejo , Arévalo José Arlés Gómez , Vallejo Ximena Caro 
Published: December 2015

<p>Este artículo hace referencia al tema de la complejidad ambiental, que centra su crítica en el proyecto moderno cientificista en el que predomina la certeza y la certidumbre, al introducir la indeterminación, la incertidumbre y otro tipo de lógicas en el campo del conocimiento y al incluir posturas epistemológicas más abarcantes en el plano social y humanístico. De la misma manera, se hace referencia al aporte de algunas tradiciones del Lejano Oriente, con las cuales comparten las ciencias de la complejidad la consideración de la interrelación de la estructura del universo, la <br />naturaleza y los seres vivos. En esta interrelación, el ser humano es concebido como un componente complejo bio-psico-social-trascendental, por lo que puede destacarse su dimensión singular, irrepetible, abierta y trascendente.</p>
Ciudadanía digital: inclusión y exclusión. Análisis de la habitabilidad en los MOOC
Authors: Chamorro Alicia Natalie , Palacios Manuel Darío 
Published: December 2015

<p>El concepto de ciudadanía en tanto isegoría e isonomía (Arendt), se hace pertinente en las nuevas formas de ciudadanía. Dentro de estas consideraciones, el discurso de la ciudadanía digital se abre un espacio en el debate contemporáneo. A partir de la definición de la ciudadanía digital como “aquel individuo, ciudadano o no, de otra comunidad o Estado, que ejerce la totalidad o parte de sus derechos políticos o sociales a través de Internet de forma independiente o por medio de su pertenencia a una comunidad virtual” (José Manuel Robles), surgen las reflexiones en torno a la manera en que esta se propicia en los entornos legislativos locales y en un mundo globalizado. Tras este análisis, se procede a la consideración de la desigualdad digital (un nuevo tipo de analfabetismo), que sigue marcando una brecha entre los países del “primer mundo” y los “países del tercer mundo”, y que dificulta la inclusión en el orden de la configuración de una nueva ciudadanía.</p>

Published: December 2015

RESUMONeste trabalho foi investigada a atividade fotocatalítica de filmes de TiO2 crescidos eletroquimicamente por anodização potenciostática e dopados quimicamente. Os filmes foram tratados termicamente para conversão do TiO2 amorfo à fase cristalina anatase. Foram sintetizados filmes dopados com prata (TiO2/Ag) e com nitrogênio (TiO2/N). A atividade fotocatalítica dos filmes foi estudada usando se o alaranjado de metila como composto modelo. Observou-se que a atividade fotocatalítica dos filmes dopados é maior do que a do filme puro. Ambos os filmes dopados apresentam fotoatividades similares. O aumento da atividade fotocatalítica se deve provavelmente à inserção de níveis de energia superficiais e/ou defeitos que podem estar inibindo a taxa de recombinação e-/h+ e consequentemente aumentam a atividade fotocatalítica dos filmes. PALAVRAS-CHAVE: Fotocatálise, Dióxido de Titânio, Dopagem. PHOTOBLEACHING OF METHYL ORANGE USING THE NANOPOROUS FILMS TIO2, TIO2 / AG , TIO2 / N . ABSTRACTIn this study it was investigated the photocatalytic activity of TiO2 films grown by electrochemical anodization at a constant voltage and chemically doped. The films were annealed for conversion of amorphous to anatase TiO2 crystalline phase. The synthesized films were chemically doped using silver (TiO2 / Ag) and with nitrogen (TiO2/N). The photocatalytic activity of the films was studied using the methyl orange as model compound. It was observed that the photocatalytic activity of the doped films is higher than pure TiO2 film. Both doped films have similar fotoactivities. The increase of photocatalytic activity is probably due to insertion of surface energy levels and/or defects that may be inhibiting the recombination rate of e-/ h+ and consequently increase the photocatalytic activity of the films.

The Opportunities and Challenges of an Interdisciplinary Clinic
Authors: Galowitz Paula 
Published: December 2015

<p>Law school clinics in many countries increasingly provide the major opportunities that law students have to engage in interdisciplinary collaborations with other professionals. The collaboration may be with a wide range of professionals, such as: doctors and medical students; social workers and social work students; business school students; engineering faculty and students including biomedical engineering students; nursing students; and experts in public health, education, mental health or palliative care. It can occur in diverse contexts or targeted to specific populations, such as children, the elderly, victims of domestic violence or low-income business owners.</p><p>Some examples of these interdisciplinary clinics illustrate their variety. Clinical legal education initiatives in South Africa, Thailand and Ukraine promoted public health through programs that partnered with the Law and Health Initiative of the Open Society Institute’s Public Health Programs. In South Africa, palliative care was integrated with legal services; law students worked with staff at a hospice association to conduct workshops on wills, debts and family law for hospice caregivers. In Ukraine a Medical Law Clinic was started to advise and represent clients; in Thailand a law clinic wrote an HIV/AIDS Community Legal Education Manual, collaborated with organizations working on health and human rights issues to discuss harm reduction and incarceration, and implemented community education programs in prisons, detention centers and community centers. At Palacky University in the Czech Republic a new Patient’s Rights Legal Clinic, which prepares students to give legal advice, is taught by lecturers of the medical faculty and lawyers from a human rights non-profit. A clinic in the United States provides business planning and legal advice to small businesses; law and business students collaborate to assist with community economic development. Another United States clinic combines students in law, business, medicine, social work, biomedical engineering, and arts and sciences in a collaboration focused on intellectual property and business formation, with an emphasis on biodiversity and agricultural-biotechnology innovations.</p>
‘First they tell us to ignore our emotions, then they tell us to reflect’: The development of a reflective writing pedagogy in clinical legal education through an analysis of student perceptions of reflective writing.
Authors: Spencer Rachel 
Published: December 2015

<p>The use of reflective writing has long been recognised as an important component of clinical legal education pedagogy, not least because it provides an important link between the twin pillars of CLE. However, current literature about reflective writing exposes a gap about student perceptions of reflective writing.</p><p>This article provides an analysis of the results of formal research that was conducted into student perceptions of reflective writing in the clinical legal education context. The research was designed to investigate whether students perceived any benefit from reflective writing and what difficulties they actually encountered in writing in a way that is particularly different to other forms of academic assessment.</p><p>This article focusses on student perceptions of the benefits of reflective writing. A further aim of the research was to develop an improved pedagogy of reflective writing in the clinical legal education context. The article concludes that students perceive limited benefits from reflective writing and offers several suggestions and recommendations as to how this limited perception might be enhanced.</p>

Fate of Effluent‐Borne Nitrogen in the Mounded Drainfield of an Onsite Wastewater Treatment System
Authors: De Mriganka , Toor Gurpal S. 
Published: December 2015

Core Ideas
Water filled porosity (WFP) controlled N dynamics in the drainfields.
Sand layer was hotspot for nitrification due to 0.07–0.32 WFP.
Soil layer was hotspot for denitrification due to 0.55–0.91 WFP.
Organic N was mobile in the vadose zone and leached below drainfields.
Onsite wastewater treatment systems (OWTS), commonly known as septic systems, are increasingly recognized as a potential source of nitrogen in the shallow groundwater. Our objective was to investigate the effect of hydrological and biogeochemical factors in the vadose zone on the fate of effluent‐borne N in the drainfields of a drip‐dispersal OWTS. Three lysimeters (152.4 cm long, 91.4 cm wide, and 91.4 cm high) were constructed using pressure‐treated wood to mimic OWTS drainfields. Each lysimeter had three distinct layers of gravel–sand mixture, soil, and commercial sand. A drip tube, which was covered with commercial sand before planting St. Augustine grass (Stenotaphrum Trin.) on the top and sides of the lysimeters, dispersed 9 L of septic tank effluent (STE) per day on top of the stacked layers. Each lysimeter was instrumented with 10 multi‐probe sensors to determine the water content, electrical conductivity (EC), and temperature in the center and sides of sand and soil layers. Leachate samples were collected over 67 events, which consisted of one sample every 24 h for 15 d (n = 15) and weekly flow‐weighted composite samples (n = 52). In all events, the pH, EC, and chloride were lower in the leachate than STE. Daily multi‐probe data showed that EC was greater in the center than sides of the lysimeters due to more STE interaction. Sensor water content data were used to calculate water filled porosity (WFP), which was greater in the soil (0.55–0.9) than sand (0.07–0.32) due to the textural differences. Mean total N was 70 mg L−1 in the STE, which reduced to 27.4 mg L−1 in the leachate likely due to the denitrification in the soil layer. The dominance of NOx–N in the leachate (61%) as compared to STE (0.6%) was attributed to the nitrification in the sand layer. Higher proportion of organic N in the leachate (39%) than STE (16%) suggests that organic N was mobile in the vadose zone and leached below the drainfields. We conclude that hydrological and biogeochemical controls in the vadose zone play an important role in N transformations and transport of NOx–N and organic N below OWTS drainfields.
Managing Phosphorus Leaching in Mid‐Atlantic Soils: Importance of Legacy Sources
Authors: Toor Gurpal S. , Sims J. Thomas 
Published: December 2015

Core Ideas
Higher P leaching from P‐saturated mid‐Atlantic soils.
Preferential flow caused more P leaching in fine‐textured soils.
Matrix flow reduced P leaching from coarse‐textured soils.
Use both P saturation ratio and flow pathways to predict the risk of P leaching.
Application of phosphorus (P) inputs to soils saturated with legacy P can significantly increase the risk of P leaching and deteriorate water quality. Our objectives were to quantify the effect of soil type and extent of P saturation on P leaching and determine the suitability of a rapid, inexpensive soil P saturation test for use in P leaching risk assessment protocols. We collected 18 undisturbed lysimeters (30‐cm diameter, 50 cm deep), using a tractor‐mounted corer, from three typical mid‐Atlantic soils in Delaware, where P leaching is a concern. The soils were selected on the basis of Mehlich‐3 P saturation ratio (M3‐PSR) of optimum (<0.10) to environmental (>0.15) thresholds. Lysimeters were irrigated with the equivalent of 50 mm of water each week for a total of 16 wk. Concentrations of dissolved reactive P (DRP) and total P in leachate were not significantly different between optimum and environmental M3‐PSR lysimeters before fertilizer application (Weeks 1–8). However, concentrations of DRP and total P significantly increased after fertilizer application at 85 kg P ha−1 (Weeks 9–16) in the environmental M3‐PSR lysimeters. Among three soils in both M3‐PSR categories, concentrations and loads of P leached were higher from the Matapeake silt loam and Pocomoke sandy loam due to preferential leaching that limited contact of flowing water and P with the soil P‐fixing constituents (Fe, Al, and Ca), while P leaching was lower from Woodstown sandy loam due to matrix flow that resulted in greater interaction of water and P with the soil constituents. These results provide clear evidence of a greater risk of P leaching from P‐saturated soils with preferential flow pathways and show that the M3‐PSR along with information about preferential flow pathways should be used to predict the risk of P leaching.
