Mapping environmental pollution disclosures in Tunisia
Authors: Garoui Nassreddine , Chakroun Raida , Ben Mohamed Ezzeddine
Published: July 2017

The aim of this paper is to examine the mental models of actors in Tunisian firms with respect to the environmental pollution. The authors use a cognitive map to observe these mental diagrams and to visualize ways to conceptualize the environmental pollution and to understand this concept through the presentation and analysis of the cognitive maps of Tunisian firm’s actors. Each actor’s systematic exploration grid shows a balance of concepts that expresses their cognitive orientation. Thus, the authors visualize the concepts (variables) that structure the cognitive universe of the actors, which is projected in terms of influences and dependencies. This research provides some lines of thought about environmental and pollution reporting that should be explored further. The research can only help to launch a debate on corporate accountability and transparency.
Sustainable development: biofuels in agriculture
Authors: Cheteni Priviledge
Published: July 2017

Biofuels are socially and politically accepted as a form of sustainable energy in numerous countries. However, cases of environmental degradation and land grabs have highlighted the negative effects to their adoption. Smallholder farmers are vital in the development of a biofuel industry. The study sought to assess the implications in the adoption of biofuel crops by smallholder farmers. A semi-structured questionnaire was administered to 129 smallholder farmers who were sampled from the Eastern Cape Province in South Africa. A binary probit model was used to investigate the determinants of smallholder farmers adopting biofuel crops. The empirical results showed that the variables, such as membership in association, occupation and incentives were statistically significant in influencing farmers’ decision to adopt biofuel crops. Furthermore, it was discovered that the studied areas have a potential to grow biofuel crops.

La consideración de Hintikka del axioma de elección y del desafío constructivista
Authors: Jovanović Radmila
Published: July 2017

En el presente trabajo confrontamos el análisis del axioma de elección de Martin - Löf con la posición de J. Hintikka respecto de este axioma. Hintikka afirma que su Semántica Teorética de Juegos (STJ) para una Lógica de la Independencia Amigable (Lógica IA), justifica el axioma de elección de Zermelo en un sentido de primer orden perfectamente aceptable para los constructivistas. De hecho, los resultados de Martin - Löf conducen a las siguientes consideraciones:La versión preferida de Hintikka del axioma de elección, es ciertamente aceptable para los constructivistas y su significado no implica una lógica de orden superior.Sin embargo, la versión aceptable para los constructivistas se basa en una consideración intensional sobre las funciones. La extensionalidad es el corazón de la comprensión clásica del axioma de Zermelo y esta es la razón real tras el rechazo constructivista de éste.En general, las características de dependencia e independencia que motivan la Lógica IA, pueden formularse en el marco de la Teoría de Tipos Constructiva ( TTC ) sin tener que pagar el precio de un sistema que no es ni axiomatizable ni tiene una teoría subyacente de la inferencia – la lógica trata sobre la inferencia después de todo.Concluimos señalando que los recientes desarrollos en lógica dialógica muestran que el enfoque TTC hacia el significado, en general, y hacia el axioma de elección, en particular, es connatural al enfoque de la teorética de juegos, donde las características metalógicas (standard) se despliegan explícitamente a nivel del lenguaje - objeto. Por tanto, de algún modo, esto justifica, aunque de una manera bastante diferente, la exhortación de Hintikka por la fecundidad de la Semántica Teorética de Juegos en el contexto de los fundamentos de las matemáticas.
Resistencia y Fagocitación. Encuentro entre Michel de Certeau y Rodolfo Kusch
Authors: Finola Hugo Alberto
Published: July 2017

El siguiente trabajo intenta vincular las nociones de resistencia y táctica, presentes en la obra de Michel de Certeau, con la de fagocitación acuñada por Rodolfo Kusch. La gran historia, definida por Kusch y vinculada por nosotros a la cotidianidad, opera como horizonte de comprensión. Nos valemos para eso de un recorrido por algunas obras de los autores, a lo que sumamos nuestra propia experiencia de campo, durante nuestra estancia de ocho años en el precordillerano pueblo de San Pedro de Atacama (hoy Chile).
Universales, absolutos e inalienables: los derechos indestructibles
Authors: Álvarez Gálvez Íñigo
Published: July 2017

Existe una determinada teoría moral en la que se conciben los derechos humanos como derechos indestructibles (como derechos inalienables, universales y absolutos). Utilizando las palabras de Dworkin podríamos decir que esa es una buena forma de tomarse en serio los derechos. Sin embargo, podemos preguntarnos también si hay otro modo de tomarse los derechos tan en serio como Dworkin dice sin defender esa teoría. Desde este punto de vista, quizá los derechos humanos no puedan ser concebidos como absolutos (en el sentido de que no pueden ser derrotados en ninguna circunstancia); ni válidos universalmente (salvo que resolvamos primero la cuestión de la validez de los sistemas morales y jurídicos); ni siquiera inalienables. ¿Podemos decir que esta es una forma de tomarse en serio los derechos?
Interaction et révision de croyances
Authors: Dango Adjoua Bernadette
Published: July 2017

Cette étude vise à concevoir des systèmes de révision dans lesquels l’acquisition de connaissances et les aspects interactifs de la signification sont saisis comme un jeu de questions et de réponses par rapport à un ensemble initial d’hypothèses exprimé dans le langage-objet. Ce processus s’effectue par un déploiement progressif de contenus hypothétiques dans un contexte d’interaction en crédibilisant l’information que reçoit l’agent. Cette étude donne également la possibilité d’exprimer avec aisance les aspects interactifs de la signification dans les tableaux sémantiques. Et met ainsi en exergue les notions d’actes de langage par la connexion entre dialogues et tableaux dans le contexte de la révision des croyances.
Análisis de la teoría genética a la luz de la estructura de las revoluciones científicas
Authors: Martínez-Gómez Pedro , Cuevas-Badallo Ana , Cerezo María
Published: July 2017

En estos momentos nos encontramos en el ámbito de la biología molecular en una nueva etapa, denominada Post-Genómica, que se caracteriza desde un punto de vista epistémico y metodológico por la incorporación de nuevos métodos de secuenciación tanto de ADN como de ARN, y por el desarrollo de genomas que permiten referenciar de una forma precisa los resultados moleculares obtenidos. Además, se está produciendo un cambio de perspectiva sobre la expresión de caracteres donde el foco se centra en el estudio del ARN. Esta nueva perspectiva biológico-molecular basada en las nuevas metodologías y enfoques está afectando a la Teoría Genética Molecular existente así como a la definición de gen y del Dogma Central de la Biología Molecular. El principal reto filosófico que plantea esta nueva situación consiste en analizar si estamos ante una sofisticación aún mayor de la Teoría Genética Molecular o ante un cambio completo de paradigma que producirá una Nueva Teoría Genética de Procesos Moleculares además de una inconmensurabilidad con las teorías científicas precedentes derivada de los cambios que originan estas nuevas metodologías. En este trabajo evaluamos estos cambios a la luz de algunas ideas de Kuhn con el  fin de plantear una alternativa entre una interpretación moderada que entendería que la Post-genómica no entraña propiamente un cambio de paradigma o, si lo hace, se trata de una revolución menor, y una interpretación fuerte para la que las anomalías que la Post-genómica descubre en la Genética Molecular y los cambios conceptuales y metodológicos por ellas entrañadas suponen un cambio de paradigma científico.
On a Dialogical Point of View of Matrices
Authors: Cardascia Pierre
Published: July 2017

La logique dialogique ordinaire propose un traitement de la mémoire sous la forme d'un historique des dialogues. Rechercher une référence (la justification) dans cet historique est un processus ambiguë en cas de répétition, ce qui peut rendre complexes ou impossibles les questions de composition de dialogue. Ainsi, deux recherches de justification peuvent se superposer en une double justification problématique. De plus, ce traitement de la mémoire coûte techniquement beaucoup de ressources.Nous proposons un formalisme de la dialogique qui résout ces problèmes: double-justification, composition, économie de mémoire. Pour ce faire, nous internaliserons des règles analysées comme "spéciales", reconfigurant en grande partie le formalisme et à sa suite les notions philosophiques voire métaphysiques mises en jeu dans ce système logique et dans ses interprétations.Cet article se découpe en trois parties :Une présentation du cadre dialogique orientée vers la présentation du problème de la double justification.Une ré-interprétation de ce cadre en termes de matrices : les formules logiques calquées sur la lecture linguistico-mathématique du langage sont remplacées par un concept emprunté à la game semantic, celui de position (sous la forme de matrices de formules).Une brève synthèse des nouvelles perspectives offertes par cette méthode : réaffirmation de la séparation claire entre les différents niveaux d'analyse et économie sur la quantité de mémoire requise (payée en complexité).
Probabilidad y contratos. Sobre el pragmatismo de Roberto Torretti
Authors: Teira David
Published: July 2017

Pretendo establecer aquí un diálogo con la concepción pragmatista de la probabilidad defendida por Roberto Torretti a partir del enfoque propensionista. En la primera parte del trabajo, quiero mostrar en qué sentido la esperanza matemática formalizaba un principio aristotélico de justicia. En la segunda parte ilustraré, apoyándome en los trabajos de G. Shafer y V. Vovk, cómo iluminar sistemáticamente esa normatividad a partir de una concepción de la probabilidad articulada sobre la teoría de juegos. Veremos así cómo hay una dimensión pragmatista en la probabilidad que cumple con los desiderata de Torretti, aunque no se apoye en simetrías físicas.

Whether change in physical activity over time modifies the genetic susceptibility to long-term weight gain is unknown. We calculated a BMI–genetic risk score (GRS) based on 77 BMI-associated single nucleotide polymorphisms (SNPs) and a body fat percentage (BF%)-GRS based on 12 BF%-associated SNPs in 9,390 women from the Nurses’ Health Study (NHS) and 5,291 men from the Health Professionals Follow-Up Study (HPFS). We analyzed the interactions between each GRS and change in physical activity on BMI/body weight change within five 4-year intervals from 1986 to 2006 using multivariable generalized linear models with repeated-measures analyses. Both the BMI-GRS and the BF%-GRS were associated with long-term increases in BMI/weight, and change in physical activity consistently interacted with the BF%-GRS on BMI change in the NHS (P for interaction = 0.025) and HPFS (P for interaction = 0.001). In the combined cohorts, 4-year BMI change per 10-risk allele increment was −0.02 kg/m2 among participants with greatest increase in physical activity and 0.24 kg/m2 among those with greatest decrease in physical activity (P for interaction < 0.001), corresponding to 0.01 kg versus 0.63 kg weight changes every 4 years (P for interaction = 0.001). Similar but marginal interactions were observed for the BMI-GRS (P for interaction = 0.045). Our data indicate that the genetic susceptibility to weight gain may be diminished by increasing physical activity.
WOMEN MIGRANT WORKERS AND SOCIAL PROTECTION SYSTEMS IN THE PHILIPPINES
Authors: Wibowo Purwo Purwowi
Published: July 2017

Women migrant workers often face a variety of problems in the workplace, for example violence, sexual abuse, rape, extortion, and so on. Social protection systems for women migrant workers in other countries are very important. In the Philippines, there are two social protection systems to improve social welfare for vulnerable populations. Two models of social protection called the health care system and social health insurance. Both social protection systems can be managed, as based on: (1) culture value, (2) to be funded by the financial institutions, (3) implemented freely, (4) the scheme is combined with the national health insurance system, (5) able to create a high quality service. The conditions of women migrant workers are more vulnerable than male workers. So, the social protection for women migrant workers is urgent and need policies to protect them. The Government of the Philippines emphasizes the problems related to the obligation of women migrant workers to have right information and guidance before they leave the country in order to minimize social problems. Finally, social protection, not only in the Philippines, but also cooperation among countries to ptotect women migrant workers by making policy of social protection from local, national, regional, and international level.

TRANSPLANTING MEDIATION INTO INDONESIAN CIVIL JUDICIAL SYSTEM
Authors: Benny Riyanto , Hapsari Tunjung , Dewi Nurul
Published: July 2017

Mediation which has been integrated to court since 2003, was the result of transplantation from the United States of America with a low rate of success. If it is evaluated with the law of the non-transferable law by Robert B. Seidman, the rule of law derived from a country which is formed based on its socio-cultural condition cannot be automatically applied to a certain group of people living with a different socio-cultural awareness. The objective of the research is to find a suitable mediation concept to be applied in civil case litigation and to find out factors influencing the less-successful court connected mediation in Indonesia. This is a qualitative research using socio legal approach. Primary data obtained through interviews, secondary data obtained through document review. Based on qualitative analysis, it is found out that the suitable mediation concept applied in civil case litigation was repositioned as one of requirements to file a suit. Factors influencing less-successful court connected mediation in Indonesia are law and legislation, law enforcement officers, facilities and infrastructure, society and culture.

Formas teóricas de lealtad en la izquierda analógica: Beuchot auxilia a Rorty
Authors: Enrici Aldo
Published: July 2017

El presente artículo pretende explorar las razones por las que Richard Rorty, desde su filosofía, advirtiera en 1998 la aparición de un líder político como Donald Trump. El motivo sobresaliente esgrime  su desconfianza por la izquierda cultural. Rorty aboga por una izquierda reformista junto a una actitud académica solidaria, preocupada por los pobres, pero además por ampliar una intelectualidad  que traza un vínculo entre la lealtad política y la solidaridad científica. Se suma a Rorty la consideración de la hermenéutica analógica de Mauricio Beuchot, cuya contribución fortalece a la izquierda actual.

Este artículo expone dos planos aparentemente disyuntos: la lógica y la metodología de la investigación conjuntamente con la sociología y la política. Mientras que se elabora un cuadro acerca de la tipología de modelos científicos, se expone que este cuadro, fundamental como es, no es ajeno a otras expresiones y dinámicas en la sociedad y en el mundo de hoy. La idea, simple y llanamente consiste en elaborar un fresco acerca de las relaciones entre ciencia y complejidad.
Análisis documental de la Ley 1562 del 11 de julio de 2012
Authors: Bedoya Elias
Published: July 2017

En la presente reflexión sobre el nuevo Sistema de Riesgos Laborales en Colombia, se plantea la manera en que este evolucionó, cambiando su contexto de ámbito profesional a laboral, abarcando la ampliación de las definiciones de accidente de trabajo y enfermedad laboral. Además, se aborda la temática sobre la variación en la denominación Programa de Salud Ocupacional, el cual pasa a ser definido como “Sistema de Gestión de la Seguridad y Salud en el Trabajo”; esto trae consigo una dinámica totalmente diferente ala antes planteada por la extinta Resolución 1016 de 1989, en cuanto a la constitución y la dinámica que esta nueva norma exige. Lo anterior debe ser cumplido por las empresas de los distintos sectores económicos, abordando las nuevas disposiciones de las juntas de calificación de invalidez, sus funciones y características, de igual forma, los aspectos de las garantías que ofrece del Estado en la aplicación de la normativa de riesgos laborales, las cotizaciones al sistema, obligaciones de los empleadores y reportes de accidentes e inspectores de trabajo.

Published: July 2017

En los sistemas de Aprendizaje Colaborativo Soportado por Computadoras no alcanza con organizar a los estudiantes en grupos. El éxito en las experiencias de colaboración está condicionado (entre otros factores) por los roles que tanto estudiantes como profesores sean capaces de manifestar durante la dinámica de trabajo. En este artículo se presentan dos sistemas basados en agentes especialmente diseñados. El primero está enfocado tanto a monitorear los roles de equipo desempeñados por los estudiantes en la dinámica de colaboración, como a intervenir de manera automática con acciones correctivas cuando esos roles no se muestran adecuadamente. El segundo sistema basado en agentes apunta tanto a la detección de conflictos grupales que requieran la intervención del profesor para resolverse, como a llevar a cabo el entrenamiento de esos profesores en la manifestación de los roles adecuados para resolver esos conflictos. Ambos sistemas están actualmente en desarrollo para su posterior validación experimental con estudiantes y docentes reales.

Making Sense of Low Back Pain and Pain-Related Fear
Authors: Bunzli Samantha , Smith Anne , Schütze Robert , Lin Ivan , O'Sullivan Peter
Published: July 2017

Synopsis

Pain-related fear is implicated in the transition from acute to chronic low back pain and the persistence of disabling low back pain, making it a key target for physical therapy intervention. The current understanding of pain-related fear is that it is a psychopathological problem, whereby people who catastrophize about the meaning of pain become trapped in a vicious cycle of avoidance behavior, pain, and disability, as recognized in the fear-avoidance model. However, there is evidence that pain-related fear can also be seen as a common-sense response to deal with low back pain, for example, when one is told that one's back is vulnerable, degenerating, or damaged. In this instance, avoidance is a common-sense response to protect a “damaged” back. While the fear-avoidance model proposes that when someone first develops low back pain, the confrontation of normal activity in the absence of catastrophizing leads to recovery, the pathway to recovery for individuals trapped in the fear-avoidance cycle is less clear. Understanding pain-related fear from a common-sense perspective enables physical therapists to offer individuals with low back pain and high fear a pathway to recovery by altering how they make sense of their pain. Drawing on a body of published work exploring the lived experience of pain-related fear in people with low back pain, this clinical commentary illustrates how Leventhal's common-sense model may assist physical therapists to understand the broader sense-making processes involved in the fear-avoidance cycle, and how they can be altered to facilitate fear reduction by applying strategies established in the behavioral medicine literature.

Tecnoliquidità: nuovi scenari (evolutivi?) per la salute mentale
Authors: Cantelmi Tonino , Lambiase Emiliano
Published: July 2017

In questo lavoro, gli autori hanno voluto analizzare la novità e gli aspetti fondamentali positivi e negativi, di quella che è stata chiamata "Rivoluzione digitale" e della società tecnoliquida, mettendo in luce come queste esaltano e plasmano alcune caratteristiche dell'uomo liquido: il narcisismo, la velocità, l'ambiguità la ricerca di emozioni e il bisogno di infinite relazioni "light". Gli autori si sono concentrati sull'impatto che la Rete detiene sulle cognitive functions, in particolar modo su attenzione, memoria e apprendimento. Rispetto all'apprendimento, studi longitudinali hanno messo in luce come l'utilizzo del computer a scuola determini un calo dei risultati sia nella scrittura che nella lettura non dando la possibilità all'alunno di stimolare tracce mnemotecniche motorie che si attivano nella percezione della lettura e che ne facilitano il riconoscimento visivo. Inoltre vengono brevemente descritte le manifestazioni patologiche conseguenti all'eccessivo utilizzo della tecnologia digitale: ansia, depressione, fobie sociali, insonnia ed altre.Parole chiave: rivoluzione digitale, cognitive functions, psicopatologia
Locating Emergency Facilities Using the Weighted k-median Problem: A Graph-metaheuristic Approach
Authors: Kaveh Ali
Published: July 2017

An efficient approach is presented for addressing the problem of finding the optimal facilities location in conjunction with the k-median method. First the region to be investigated is meshed and an incidence graph is constructed to obtain connectivity properties of meshes. Then shortest route trees (SRTs) are rooted from nodes of the generated graph. Subsequently, in order to divide the nodes of graph or the studied region into optimal k subregions, k-median approach is utilized. The weights of the nodes are considered as the risk factors such as population, seismic and topographic conditions for locating facilities in the high-risk zones to better facilitation. For finding the optimal facility locations, a recently developed meta-heuristic algorithm that is called Colliding Bodies Optimization (CBO) is used. The performance of the proposed method is investigated through different alternatives for minimizing the cost of the weighted k-median problem. As a case study, the Mazandaran province in Iran is considered and the above graph-metaheuristic approach is utilized for locating the facilities.
Function Modeling Improves the Efficiency of Spatial Modeling Using Big Data from Remote Sensing
Authors: Hogland John , Anderson Nathaniel
Published: July 2017

Spatial modeling is an integral component of most geographic information systems (GISs). However, conventional GIS modeling techniques can require substantial processing time and storage space and have limited statistical and machine learning functionality. To address these limitations, many have parallelized spatial models using multiple coding libraries and have applied those models in a multiprocessor environment. Few, however, have recognized the inefficiencies associated with the underlying spatial modeling framework used to implement such analyses. In this paper, we identify a common inefficiency in processing spatial models and demonstrate a novel approach to address it using lazy evaluation techniques. Furthermore, we introduce a new coding library that integrates Accord.NET and ALGLIB numeric libraries and uses lazy evaluation to facilitate a wide range of spatial, statistical, and machine learning procedures within a new GIS modeling framework called function modeling. Results from simulations show a 64.3% reduction in processing time and an 84.4% reduction in storage space attributable to function modeling. In an applied case study, this translated to a reduction in processing time from 2247 h to 488 h and a reduction is storage space from 152 terabytes to 913 gigabytes.
Development of Phosphorothioate DNA and DNA Thioaptamers
Authors: Volk David , Lokesh Ganesh
Published: July 2017

Nucleic acid aptamers are short RNA- or DNA-based affinity reagents typically selected from combinatorial libraries to bind to a specific target such as a protein, a small molecule, whole cells or even animals. Aptamers have utility in the development of diagnostic, imaging and therapeutic applications due to their size, physico-chemical nature and ease of synthesis and modification to suit the application. A variety of oligonucleotide modifications have been used to enhance the stability of aptamers from nuclease degradation in vivo. The non-bridging oxygen atoms of the phosphodiester backbones of RNA and DNA aptamers can be substituted with one or two sulfur atoms, resulting in thioaptamers with phosphorothioate or phosphorodithioate linkages, respectively. Such thioaptamers are known to have increased binding affinity towards their target, as well as enhanced resistance to nuclease degradation. In this review, we discuss the development of phosphorothioate chemistry and thioaptamers, with a brief review of selection methods.
Experimental In-Plane Evaluation of Light Timber Walls Panels
Authors: Branco Jorge , Matos Filipe , Lourenço Paulo
Published: July 2017

In general, the satisfactory seismic performance of timber buildings can be partially attributed to the material characteristics of the wood itself and to the lightness of its own structure. The aim of this paper is to analyze the in-plane behavior of light timber walls panels through a series of monotonic and cyclic tests, and to evaluate how the sheathing material and the fixation to the base influence the overall response of the wall. Five tests are presented and discussed while the reliability of an analytical method to predict the response of the walls is studied. The sheathing material revealed to be important in the overall response of the wall. Moreover, the type of fixation to the base also revealed to be important in the in-plane response of timber walls. In-plane stiffnesses, static ductility, energy dissipation and damping ratio have been quantified.
Blended Drought Index: Integrated Drought Hazard Assessment in the Cuvelai-Basin
Authors: Luetkemeier Robert , Stein Lina , Drees Lukas , Liehr Stefan
Published: July 2017

Drought is one of the major threats to societies in Sub-Saharan Africa, as the majority of the population highly depends on rain-fed subsistence agriculture and traditional water supply systems. Hot-spot areas of potential drought impact need to be identified to reduce risk and adapt a growing population to a changing environment. This paper presents the Blended Drought Index (BDI), an integrated tool for estimating the impact of drought as a climate-induced hazard in the semi-arid Cuvelai-Basin of Angola and Namibia. It incorporates meteorological and agricultural drought characteristics that impair the population’s ability to ensure food and water security. The BDI uses a copula function to combine common standardized drought indicators that describe precipitation, evapotranspiration, soil moisture and vegetation conditions. Satellite remote sensing products were processed to analyze drought frequency, severity and duration. As the primary result, an integrated drought hazard map was built to spatially depict drought hot-spots. Temporally, the BDI correlates well with millet/sorghum yield (r = 0.51) and local water consumption (r = −0.45) and outperforms conventional indicators. In the light of a drought’s multifaceted impact on society, the BDI is a simple and transferable tool to identify areas highly threatened by drought in an integrated manner.

Tantalum carbide (TaC) and silicon carbide (SiC) layers were deposited on a graphite tube using a chemical vapor deposition process. Tantalum chloride (TaCl5) was synthesized in situ by reacting tantalum chips with chlorine at 550 °C. TaC was deposited by reacting TaCl5 with CH4 in the presence of H2 at 1050–1150 °C and 50–100 mbar. SiC was deposited at 1000 °C using methyl-tri-chloro-silane as a precursor at 50 mbar. At 1150 °C; the coating thickness was found to be about 600 μm, while at 1050 °C it was about 400 μm for the cumulative deposition time of 10 h. X-ray diffraction (XRD) and X-ray Photo-Electron Spectroscopy (XPS) studies confirmed the deposition of TaC and SiC and their phases. Ablation studies of the coated specimens were carried out under oxyacetylene flame up to 120 s. The coating was found to be intact without surface cracks and with negligible erosion. The oxide phase of TaC (TaO2 and Ta2O5) and the oxide phase of SiC (SiO2) were also found on the surface, which may have protected the substrate underneath from further oxidation.

The ultraviolet (UV) component of sunlight is high on the earth surface, especially at low latitudes, raising the risk of skin diseases, including cancer. The use of natural compounds is a strategy to protect people against UV damage. Seaweeds are becoming increasingly influential in the food industry, and are also used in the pharmacy and cosmetic industries, due to several bioactive demonstrated properties. This work analyzed the genotoxic and photoprotective effects of the aqueous extracts of two seaweed species: Bryothamnion triquetrum and Halimeda incrassata. A cell-free plasmid DNA assay was employed, allowing detection of DNA breaks. The plasmids were exposed to increasing concentrations of aqueous extracts. DNA break was produced at concentrations of 2.0 and 4.0 mg/mL in both seaweed extracts and, consequently, a genotoxic effect is postulated. This effect arises with higher exposure times. Additionally, different combinations of plasmid DNA, restriction enzymes (Eco RI, Bam HI, and Pvu II) and extracts were assayed. The extracts did not produce an interference effect in the reconnaissance of the specific restriction target sequences of each enzyme. Photoprotective activity of the extracts was evaluated in UVC-irradiated plasmids. None of the extracts displayed DNA protective effects in this assay.

Thermal oil has been used as heat transfer fluid in many solar thermal power plants, which also use molten salts as thermal energy storage system. Since the engineering of these plants is relatively new, control of the thermal energy storage system is currently achieved in manual or semiautomatic ways, controlling its variables with proportional-integral-derivative (PID) regulators. Once the plant is running, it is very difficult to obtain permission to try new control strategies. Hence, most plants keep running on these simple, sometimes inefficient control algorithms. This paper explores the results obtained with different control strategies implemented on a complete model of energy storage systems based on molten salt. The results provided by the model allow the optimum control strategy to be selected. Comparison of the results obtained by simulation of these control strategies and actual results obtained from a real plant, confirm the accuracy of the selection made.
Bluetooth 5 Energy Management through a Fuzzy-PSO Solution for Mobile Devices of Internet of Things

Published: July 2017

Energy efficiency is a fundamental requirement for a wireless protocol to be suitable for use within the Internet of Things. New technologies are emerging aiming at an energy-efficient communication. Among them, Bluetooth Low Energy is an appealing solution. Recently, the specifications of Bluetooth 5 have been presented with the purpose to offer significant enhancements compared to the earlier versions of the protocol. Bluetooth 5 comes with new communication modes that differ in range, speed, and energy consumption. This paper proposes a fuzzy-based solution to cope with the selection of the communication mode, among those introduced with Bluetooth 5, that allows the best energy efficiency. This communication mode, used by mobile devices, is dynamically regulated by varying the transmission power, returned as the output of a Fuzzy Logic Controller (FLC). A Particle Swarm Optimization (PSO) algorithm is presented to achieve the optimal parameters of the proposed FLC, i.e., optimizing the triangular membership functions, by varying their range, to reach the best results concerning the battery life of mobile devices. The proposed FLC is based on triangular membership functions because they represent a good trade-off between computation cost and efficiency. The paper presents a detailed description of the FLC design, a logical analysis of the PSO algorithm for the derivation of best performance conditions values, and experimental assessments, obtained through testbed scenarios.
Green Streets: Urban Green and Birth Outcomes

Published: July 2017

Recent scholarship points to a protective association between green space and birth outcomes as well a positive relationship between blue space and wellbeing. We add to this body of literature by exploring the relationship between expectant mothers’ exposure to green and blue spaces and adverse birth outcomes in New York City. The Normalized Difference Vegetation Index (NDVI), the NYC Street Tree Census, and access to major green spaces served as measures of greenness, while proximity to waterfront areas represented access to blue space. Associations between these factors and adverse birth outcomes, including preterm birth, term birthweight, term low birthweight, and small for gestational age, were evaluated via mixed-effects linear and logistic regression models. The analyses were conducted separately for women living in deprived neighborhoods to test for differential effects on mothers in these areas. The results indicate that women in deprived neighborhoods suffer from higher rates adverse birth outcomes and lower levels of residential greenness. In adjusted models, a significant inverse association between nearby street trees and the odds of preterm birth was found for all women. However, we did not identify a consistent significant relationship between adverse birth outcomes and NDVI, access to major green spaces, or waterfront access when individual covariates were taken into account.

Bacterial infections of cutaneous leishmaniasis cause skin ulcers on mice, resulting in increased tissue deterioration, and these infections can be controlled with liquid allicin. To isolate and identify the incidences of real secondary bacterial infections in mice, we performed the current study by injecting mice (n = 50) with Leishmania major. L. major infections were initiated by an intramuscular injection of 0.1 mL Roswell Park Memorial Institute (RPMI 1640 media/mouse (107 promastigote/mL)). Scarring appeared 2–6 weeks after injection, and the bacteria were isolated from the skin ulcer tissues. Allicin (50 µL/mL) and ciprofloxacin (5 μg; Cip 5) were used for controlling L. major and bacteria. One hundred samples from skin ulcers of mice were examined, and 200 bacterial colonies were isolated. Forty-eight different genera and species were obtained and identified by Gram staining and physiological and biochemical characterization using identification kits. All samples were positive for secondary bacterial infections. Of the isolates, 79.16% were identified as Gram-negative bacteria, and 28.84% were identified as Gram-positive bacteria; only one yeast species was found. Interestingly, pure allicin liquid at a concentration 50 µL/mL exhibited antibacterial activity against a wide range of Gram-negative and some Gram-positive bacteria, in addition to yeast, and was 71.43% effective. Antimicrobial resistance patterns of all genera and species were determined using 15 different antibiotics. Allicin (50 µL/mL) and Cip 5 were the most effective against L. major and 92.30% of isolated bacteria. Stenotrophomonas maltophilia was the most resistant bacterium to the tested antibiotics with a survival rate of 73.33%, and it exhibited resistance to allicin.
