Flow rate of polygonal grains through a bottleneck: Interplay between shape and size
Authors: Goldberg Ezequiel , Carlevaro C. Manuel , Pugnaloni Luis Ariel 
Published: November 2015

We report two-dimensional simulations of circular and polygonal grains passing through an aperture at the bottom of a silo. The mass flow rate for regular polygons is lower than for disks\red{,} as observed by other authors. We show that both the exit velocity of the grains and the packing fraction are lower for polygons, which leads to the reduced flow rate. We point out the importance of the criteria used to define when two objects of different shape are considered to be of the same size. Depending on this criteria, the mass flow rate may vary significantly for some polygons. Moreover, the particle flow rate is non-trivially related to a combination of mass flow rate, particle shape and particle size. For some polygons, the particle flow rate may be lower or higher than that of the corresponding disks depending on the size comparison criteria.

Unnoticed Ways in which Migration Reinforces Under development
Authors: Abumere Frank Aragbonfoh 
Published: November 2015

This paper analyses how migration from low income economies to high income economies can actually have negative rather than positive consequences on development and low income economies. There are noticed ways - such as brain drain, separation from family, etc – in which migration negatively affects sending- countries. But this paper argues that there are unnoticed ways in which migration negatively affects development and low income economies. For this paper, the relationship between migration and underdevelopment is a complex rather than a simple one. It is simple to see how underdevelopment causes migration. But to see that migration in turn reinforces underdevelopment, one needs to engage in some complex analysis. Alarmingly, the end-result of the complex analysis is that migration and remittances, while alleviating poverty, can actually make: citizens neglect their duty to hold their governments responsible for underdevelopment; and governments neglect their duty to find long term solutions to the problem of underdevelopment. In terms of methodological approach, admittedly this sort of work often requires empirical methods. Nevertheless, the aim of this paper is to do a theoretical analysis which will serve as the foundation on which future empirical works can be based.Key words; Institutions, Migration, Poverty, Remittances, Underdevelopment.
A Fictional X-ray of the Contemporary Society: a Study of Akachi Adimora-Ezeigbo’s Trafficked
Authors: Nnyagu Uche , Adunchezor Ngozi 
Published: November 2015

Akachi Adimora-Ezeigbo is one of the contemporary writers who strongly affirm that a true fiction must aptly mirror the world of the writer. This, she vividly demonstrates in her Trafficked. Adimora-Ezeigbo got her inspiration for the fiction from historical and contemporary facts. In our contemporary society, female trafficking is on the increase. Many unpatriotic citizens indulge in the illegal deal which they see as a very lucrative business. Unwary young women are lured into international sex trade with lots of tantalizing promises that would eventually turn to illusions. Trafficking is frowned at in Nigeria, yet people are perpetually trafficked. In this research work, the researcher examines the novel in line with sociological approach so that the ills of human trafficking as it is a case in the contemporary society would be seen. The researcher believes that when the ills are exposed, there would be reformation.
La Scientificite En Langues Africaines : L’exemple Du Kalabari Et De L’ikwerre
Authors: Iyalla-Amadi Priye , Odungweru US 
Published: November 2015

Les langues africaines sont souvent ancrées dans un folklore riche, idiomatique et sonore, évocateur des prémices de l’humanité. Mais on peut se demander si elles sont pareillement armées pour exprimer des données objectives et des faits scientifiques. Une opération qui s’avère souvent problématique. Nous présenterons des arguments en faveur de la formulation et de l’invention de termes scientifiques en langues africaines, au travers d’une analyse des éléments du discours technique de langues où ces termes existent. Deux langues africaines du phylum Niger-Congo, le kalabari et l’ikwerre, seront étudiées et comparées à deux langues indo-européennes, l’anglais et le français, en vue de faire évoluer la pratique de la traduction scientifique en langues africaines. Une telle démarche s'inscrit dans l'objectif d'accroître la production de données scientifiques en langues africaines afin de favoriser une révolution technologique sur le continent africain.Mots clés: langues africaines, discours technique, données scientifiques, révolution scientifique.African languages are often synonymous with rich folklore and sonorous cultural renditions, reminiscent of mankind’s primeval beginnings. But what about the linguistic rendition of objective data and scientific realities? This often poses a challenge. In this paper, a case is made for formulating scientific terms and coinages in African languages by analyzing the components of technical discourse evident in languages that display them. Two African languages of the Niger-Congo phylum, Kalabari and Ikwerre, will be studied vis-à-vis two European languages of the Indo-European language family: English and French. This will be done with a view to evolving indigenous scientific translations in African languages. It is expected that such a procedure would result in the prolific production of scientific data in African languages and ultimately result in a technological breakthrough for the African continent.Key words: African languages, technical discourse, scientific data, technological breakthrough
The Creation and Uses of Letters and Forms in Graphic Illustration
Authors: Bardi Augustine 
Published: November 2015

When art was first introduced to Africa and to Nigeria in particular by the missionaries, it never came as a surprise going by the advantages of this profession in the development of the European civilization. The acceptance of art in Nigeria most especially in schools never got the highest regard particularly among parents. This is probably because its long run advantages were not clearly spelt out to the society at inception. As a result of this however, the art profession suffered numerous setbacks as few talented people are presently found embracing its popularity after many years of neglect. The Fundamentals of Art is rather cheap in formation, but remains the basics which any artist will evidently depend on to realise a successful art career. Many Studios, Workshops and other centres of apprenticeship, have introduced without delay this basic fundamentals knowing and foreseeing its future advantages in making the next successful art designer, graphic designer, ceramist, painter, sculptor, fashion designer and textiles designer, interior decorator, exterior decorator and many more. Creativity is part of creation. The art to the artists remains a function to be researched before execution, and once successfully realised, it becomes a piece to be adorned and ever cherished.Key Words: Creativity, Schools, Fundamentals, Development, Professionalism, Civilization
The Relationship between Philosophy and Culture
Authors: Agbanusi Christian Arinze 
Published: November 2015

Over the years, there has been this controversy over the relationship between philosophy and culture. It is an issue that has always polarized scholars including philosophers. On one side, a group of philosophers and scholars hold the view that philosophy is distinct from culture, whereas an opposing group is of the opinion that the two concepts are merely different names for the same thing. Using analytic and hermeneutic methods, this work takes a critical look at the two concepts -- philosophy and culture -- with a view to showing the relationship between them
Exposing the Ruins of Law: The Rhetorical Contours of Recognition's Demand
Authors: Burgess Sarah K. 
Published: November 2015

ABSTRACTThis article examines the rhetorical structure of the demand for recognition in order to refigure the relationship between law and the scene of address in political and theoretical accounts of recognition. It begins by demonstrating that theorists and critics of the politics of recognition assume that law limns the scene of recognition, framing it in a way that contains its practices and marks its end. The difficulty of such a presumption, however, is that, if law is afforded the status of a frame or background, we are unable to account for the rhetorical operations of law—the way it constitutes the norms of recognizability. A reading of the U. K.'s Gender Recognition Act of 2004 provides a brief example of how a demand for recognition might expose law's rhetorical conditions and demonstrate how legal judgment presupposes a scene of recognition in which both subjects and law take (up a) place.
Humor Across Media in the 1920s and 1930s
Authors: King Rob 
Published: November 2015

Abstract
This introduction to a special issue on American humor across media in the 1920s and 1930s frames the five essays that follow in relation to two major analytical issues. It proposes, first, that transmedial analysis attend to the material factors that support the circulation of comic tropes and personas across media forms; and second, that specific manifestations of those tropes/personas be examined in relation to the varying properties of the media involved. The 1920s and 1930s present a case study for such an investigation.

Optimization of CO2 Sequestration in Reservoirs under Geochemistry and Thermal Effects

Published: November 2015

Abstract
Disposal and long-term sequestration of anthropogenic " greenhouse gases" such as CO2 is a proposed approach to reducing global warming. Deep, regional-scale aquifers in sedimentary basins are possible sites for sequestration, given their ubiquitous nature. In order for CO2 to be stored in aquifers responsibly, it is essential to identify key concepts that need to be considered for potential implementation. Ideally, injected CO2 will migrate through an aquifer from injection wells to remote storage sites, and remain isolated from the atmosphere for a considerable period of time. Fundamental topics of interest in sequestration research have concerned not just scientific and technical aspects, but practical concerns such as the economic feasibility of storage, safety, and the maximum possible amount of CO2 storage globally and for specified regions. Thus, it is crucial to have a robust understanding of this important process not only in theory but in practice too through illustration with solid examples as in this study.
A robust commercial optimization and uncertainty software is coupled with a full-physics commercial simulator that models the phenomenon in order to investigate the significance of the major parameters on performance of wells in CO2 sequestration under geochemistry and thermal effects. CO2 injection is done for first 25 years. The injector is shut-in thereafter and the fate of CO2 is modeled for the next 225 years. Chemical equilibrium constants are functions of temperature. Trace gas is used. Molecular diffusion of CO2 in water is modeled. Thermal effects due to injection of CO2 at are modeled.
Sensitivity and optimization have been done on major reservoir parameters such as fluid and rock properties and well operational parameters and then significance of each has been illustrated in tornado diagrams. It is observed that a robust approach on handling of uncertainties in reservoir are as important as management of well operational parameters in the scope of reservoir management. Presence of impact of geochemistry and temperature effects have proven to play an important role in the process.
L’incidence des outils pédagogiques sur la visite des adolescents au musée
Authors: Champagne Marie-Ève 
Published: November 2015

L’émergence du visiteur « participant » requiert du musée l’évaluation périodique de ses approches éducatives, de façon plus particulière lorsqu’il s’agit d’adolescents. Cette clientèle bien souvent laissée pour compte a été étudiée par Marie-Ève Champagne. Cet article évalue la performance du modèle du « musée constructiviste » de Ceorge E. Hein en tant que stratégie éducative. L’enquête que l’auteure a menée auprès de 325 jeunes lui permet d’établir que ce modèle peut devenir une approche efficace auprès d’une clientèle en constante transformation.

Ruin and Reconstruction: Understanding the Constructed Past
Authors: Woltz Catherine 
Published: November 2015

Le patrimoine bâti témoigne du temps qui passe. Une fois abandonné, il tombe en décrépitude rapidement. À partir de ce moment, afin de permettre à l’histoire de survivre, deux options s’opposent et s’exposent : mettre en scène ses ruines ou reconstruire à l’identique. En comparant ces deux figures de cas à partir d’exemples britanniques, Catherine Woltz note les divergences de perceptions sensibles propres à chacune et étudie les différentes stratégies d’interprétation qui en découlent.
L’art urbain, un nouvel objet muséologique ?
Authors: Vergnaud Stéphanie 
Published: November 2015

Depuis plusieurs années déjà, des oeuvres d’art ont commencé à envahir les murs des villes. Si certaines galeries commencent à s’intéresser à cet art dit « urbain », très peu de musées lui ont ouvert leurs portes. Les artistes urbains, quant à eux, cautionnent pour une large part l’idéologie dominante de l’intégration institutionnelle et tentent d’accéder au marché de l’art. Dans cet article, Stéphanie Vergnaud propose de vérifier s’il existe ou non une dialectique entre l’espace institutionnel et l’art urbain.

Authors: Teixeira Walquíria Fernanda , Veronese Rogério , Christoffoleti Pedro Jacob 
Published: November 2015

O objetivo da pesquisa foi avaliar os efeitos de surfatante siliconado e de chuva simulada sob a eficiência do glyphosate no controle de Brachiaria decumbens. Os experimentos foram desenvolvidos na “Escola Superior de Agricultura Luiz de Queiroz” em condições de casa de vegetação, no delineamento de blocos casualizados, com quatro repetições. Em um experimento realizou-se chuva simulada de 10 mm, 30 minutos após a aplicação dos tratamentos, e no outro não ocorreu a simulação. Os tratamentos foram arranjados no esquema fatorial 5x3, com o primeiro fator correspondente as doses de glyphosate (0, 135, 270, 540 e 1080 g ha-1 e.a.), e o segundo as doses de surfatante siliconado (0, 50 e 100 mL ha-1). As aplicações foram realizadas aos 30 dias após a semeadura. Na presença de chuva simulada ocorreu o aumento do percentual de controle e redução no teor de clorofila na dose de 135 g ha-1 e.a. de glyphosate juntamente com 100 mL ha-1 de surfatante siliconado. Também foi observado aumento na peroxidação lipídica com adição de 100 mL ha-1. No experimento sem chuva simulada, aos sete dias após a aplicação dos tratamentos foi observado maior percentual de controle nas doses de 540 e 1080 g ha-1 e.a. com 100 mL ha-1 de surfatante siliconado. Portanto, o uso de surfatante siliconado na dose de 100 mL ha-1 aumenta a eficiência de glyphosate no controle de Brachiaria decumbens sem a presença de chuva simulada e em condições de chuva ocorrida até meia hora depois da aplicação.

AbstractThis article is a review of the science goals and activities initiated within the framework of the Pollution and its Impacts on the South American Cryosphere (PISAC) initiative. Air pollution associated with biomass burning and urban emissions affects extensive areas of South America. We focus on black carbon (BC) aerosol and its impacts on air quality, water availability, and climate, with an emphasis on the Andean cryosphere. BC is one of the key short‐lived climate pollutants that is a topic of growing interest for near‐term mitigation of these issues. Limited scientific evidence indicates that the Andean cryosphere has already responded to climate change with receding glaciers and snow cover, which directly affect water resources, agriculture, and energy production in the Andean region of South America. Despite the paucity of systematic observations along the Andes, a few studies have detected BC on snow and glaciers in the Andes. These, in addition to existing and projected emissions and weather patterns, suggest a possible contribution of BC to the observed retreat of the Andean cryosphere. Here we provide an overview of the current understanding of these issues from scientific and policy perspectives, and propose strategic expansions to the relevant measurement infrastructure in the region.
Vegetation regulation on streamflow intra‐annual variability through adaption to climate variations
Authors: Ye Sheng , Li Hong‐Yi , Li Shuai , Leung L. Ruby , Demissie Yonas , Ran Qihua , Blöschl Günter 
Published: November 2015

AbstractThis study aims to provide a mechanistic explanation of the empirical patterns of streamflow intra‐annual variability revealed by watershed‐scale hydrological data across the contiguous United States. A mathematical extension of the Budyko formula with explicit account for the soil moisture storage change is used to show that, in catchments with a strong seasonal coupling between precipitation and potential evaporation, climate aridity has a dominant control on intra‐annual streamflow variability. But in other catchments, additional factors related to soil water storage change also have important controls on how precipitation seasonality propagates to streamflow. More importantly, use of leaf area index as a direct and indirect indicator of the above ground biomass and plant root system, respectively, reveals the vital role of vegetation in regulating soil moisture storage and hence streamflow intra‐annual variability under different climate conditions.
