Long-term projections of global water use for electricity generation under the
Shared Socioeconomic Pathways and climate mitigation scenarios
Authors: Ando Nozomi , Yoshikawa Sayaka , Fujimori Shinichiro , Kanae Shinjiro
Published: March 2017

Abstract. Electricity generation may become a key factor that accelerates water scarcity. In this study, we estimated the future global water use for electricity generation from 2005 to 2100 in 17 global sub-regions. Twenty-two future global change scenarios were examined, consisting of feasible combinations of five socioeconomic scenarios of the Shared Socioeconomic Pathways (SSPs) and six climate mitigation scenarios based on four forcing levels of representative concentration pathways (RCPs) and two additional forcing levels, to assess the impacts of socioeconomic and climate mitigation changes on water withdrawal and consumption for electricity generation. Climate policies such as targets of greenhouse gas (GHG) emissions are determined by climate mitigation scenarios. Both water withdrawal and consumption were calculated by multiplying the electricity generation of each energy source (e.g., coal, nuclear, biomass, and solar power) and the energy source-specific water use intensity. The future electricity generation dataset was derived from the Asia-Pacific Integrated/Computable General Equilibrium (AIM/CGE) model. Estimated water withdrawal and consumption varied significantly among the SSPs. In contrast, water withdrawal and consumption differed little among the climate mitigation scenarios even though GHG emissions depend on them. There are two explanations for these outcomes. First, electricity generation for energy sources requiring considerable amounts of water varied widely among the SSPs, while it did not differ substantially among the climate mitigation scenarios. Second, the introduction of more carbon capture and storage strategies increased water withdrawal and consumption under stronger mitigation scenarios, while the introduction of more renewable energy decreased water withdrawal and consumption. Therefore, the socioeconomic changes represented by the SSPs had a larger impact on water withdrawal and consumption for electricity generation, compared with the climate mitigation changes represented by the climate mitigation scenarios. The same trends were observed on a regional scale, even though the composition of energy sources differed completely from that on a global scale.
High-magnitude flooding across Britain since AD 1750
Authors: Macdonald Neil , Sangster Heather
Published: March 2017

Abstract. The last decade has witnessed severe flooding across much of the globe, but have these floods really been exceptional? Globally, relatively few instrumental river flow series extend beyond 50 years, with short records presenting significant challenges in determining flood risk from high-magnitude floods. A perceived increase in extreme floods in recent years has decreased public confidence in conventional flood risk estimates; the results affect society (insurance costs), individuals (personal vulnerability) and companies (e.g. water resource managers). Here, we show how historical records from Britain have improved understanding of high-magnitude floods, by examining past spatial and temporal variability. The findings identify that whilst recent floods are notable, several comparable periods of increased flooding are identifiable historically, with periods of greater frequency (flood-rich periods). Statistically significant relationships between the British flood index, the Atlantic Meridional Oscillation and the North Atlantic Oscillation Index are identified. The use of historical records identifies that the largest floods often transcend single catchments affecting regions and that the current flood-rich period is not unprecedented.
Southern Criminology: Guest Editors’ Introduction
Authors: Hogg Russell , Scott John , Sozzo Máximo
Published: March 2017

Knowledge is a commodity and knowledge production does not occur in a geo-political vacuum. With respect to this, it has to be argued that neo-imperialism involves economic and knowledge flows across continuous space, which is transnational and distinct from the old forms of colonialism which were based on country-to-country occupation. In the context of contemporary geo-politics, these conditions render territorial terrain as less important than discursive terrain (Lo 2011).  So, how is global knowledge in the social sciences (and more specifically in criminology) produced and shared? Where does this production take place? Who are the producers? Whose experiences and whose voices are reflected in dominant academic discourses? How is knowledge disseminated and who gets access to it? These are some of the questions that the project of southern criminology seeks to tackle.

Emergency boarding: An integrative framework for analyzing causes and seeking solutions
Authors: Limoges Vincent , Gemmel Paul , Landry Sylvain , Paepe Peter De
Published: March 2017

Background: One of the root causes of crowding at the Emergency Department (ED) is boarding, i.e. the practice of holding admitted patients in the ED until an inpatient (IP) bed becomes available. Although ED boarding has been approached by various authors, few of them have aimed to see how different hospitals perform in regard to this issue.Objective: This study will approach ED boarding from different angles, analyzing both quantitative and qualitative data, and following both deductive and inductive reasoning. The purpose is to develop a validated integrative conceptual framework which can be used to analyze ED boarding, and to look for solutions.Methods: The development of the framework is based on an extensive literature review and a multiple case study research with both qualitative and quantitative data collection.Results: ED boarding was found to be prominent in the studied hospitals. Four root causes of ED boarding were elucidated, which are: (1) uncoordinated admissions and discharges, (2) late discharges, (3) the inability to discharge patients, and (4) a lack of communication, collaboration, and information between the different actors of the patient care process. Many solutions are proposed to improve these issues.Conclusions: Through the analysis of various types of data, an integrative conceptual framework for ED boarding was elaborated for analyzing causes and seeking solutions. The quantative data cannot only be used in the analysis stage, but can also help in designing a solution as there are clear recognizable trends in arrival, discharge and ED boarding time. “Communication, collaboration and information”, although not explicitly discussed in the literature, was found to be the most prominent cause and solution to ED boarding in the field study. Practice implications: Management practitioners now have a framework demonstrating probable causes for ED boarding, which provides a starting point for analysis within their establishments. Pathways to improvement are suggested as well, which will help managers to reduce ED boarding. Communication, collaboration and information are important in these improvement efforts.
Zero-Point Energy and the Emergence of Gravity: Two Hypotheses
Authors: Tattersall Philip J.
Published: March 2017

Building on the results of experiments and speculations arising from his earlier collaborations as well as proposals from the theoretical work of others, the author suggests that gravity emerges as a result of the interaction of zero-point energy with matter. The results of experiments suggest that light, through its interaction with zero-point energy causes changes in the weight of test masses. These experimental results are interpreted as being due to changes in the spectral [Note 1] content surrounding massive bodies. Two hypotheses therefore emerge. Further experiments are planned to test the findings from earlier experiments.

Engajamento e redução do espaço dialógico no gênero notícia de popularização científica
Authors: Scherer Anelise Scotti , Motta-Roth Désirée
Published: March 2017

A popularização da ciência (PC) envolve um processo complexo de recontextualização,  no  qual  o  discurso  científico,  produzido  por  especialistas,  é recontextualizado por jornalistas para uma audiência não especializada, em gêneros discursivos da mídia de massa. Pesquisas recentes têm apontado um efeito de monologismoem notícias de PC em português (MOTTA-ROTH; LOVATO, 2011 conforme MOIRAND, 2003) e inglês (MOTTA-ROTH; MARCUZZO, 2010), nas quais há um predomínio da voz da ciência e um apagamento de outras vozes possíveis como o governo ou o público, já identificados na mídia de PC francesa (BEACCO et al., 2002; MOIRAND, 2003). Com base em estudos prévios, o objetivo do presente artigo é apresentar uma análise engajamento discursivo e do jogo entre expansão e contração dialógica em 45 notícias de PC em inglês. Para tanto, consideramos os Sistemas de Transitividade e de Modalidade (HALLIDAY; MATTHIESSEN, 2004) e o Sistema de Avaliatividade (MARTIN; WHITE, 2005) da Linguística SistêmicoFuncional para a análise. Nossos resultados indicam que, apesar da maior recorrência de expoentes linguísticos que sugerem expansão dialógica por meio de reconhecimento, não há indicação clara de debate entre pontos de vista diferentes em nosso corpus, a não ser aqueles associados a especialistas/pesquisadores. Nesse sentido, o jornalista/autor da notícia contrai o espaço dialógico do discurso ao enfatizar a voz da ciência e, ao mesmo tempo, restringir a participação de outros setores da sociedade no debate em potencial sobre a pesquisa popularizada (MARCUZZO, 2011), reforçando, assim, a hegemonia da voz da ciência na mídia de massa.

Este trabalho tem como objetivo apresentar resultados de uma pesquisa desenvolvida na interface entre Linguística Sistêmico-Funcional (LSF) e Estudos da Tradução com foco em Tipologia Textual baseada em contexto. A base teórica do trabalho está assentada na proposta de ‘Atividades Sociossemióticas’, representada graficamente na chamada Esfera de Atividades Sociossemióticas, de Matthiessen, Wu e Teruya (2007). Apresenta-se inicialmente uma coleta de dados (blogs) compilados em formato eletrônico e relativos às tipologias textuais nos contextos do português brasileiro (PB) e inglês americano (IA). A seguir, apresenta-se a classificação dos textos coletados nesses blogs com  base  nas  ‘Atividades  sociossemióticas’.  Após  a  classificação  sócio  semiótica,  uma análise de transitividade é realizada com vistas a explorar a relação entre a Tipologia Textual baseada em contexto e os padrões gramaticais do sistema de transitividade que realizam os diferentes tipos textuais. Por fim os resultados dessa análise são comparados para  fins  de  identificar  diferenças  e  semelhanças  nas  configurações  texto-contextuais dos dois conjuntos de textos produzidos em ambos os idiomas. Os desdobramentos dessa comparação buscarão traçar um perfil ‘sociossemiótico’dos textos analisados, com vistas a fornecer um modelo de parâmetros textuais para formação de tradutores na dimensão bilíngue/ textual do desenvolvimento de suas competências.Palavras-chave: Estudos da tradução.

OS USOS FLEXÍVEIS DO CONCEITO DE VARIÁVEL NA EDUCAÇÃO BÁSICA: UM ESTUDO COM AS EQUAÇÕES DIOFANTINAS LINEARES
Authors: Pommer Wagner Marcelo
Published: March 2017

http://dx.doi.org/10.5902/2179460X14370In many curricular documents for Basic Education the variable concept is briefly quoted, seen as a paramathematics notion, intrinsic to the development of functions, without further references. This article aims to present and discuss the context of Linear Diophantine Equation as a possible theme to explore the flexible uses of the variable concept in algebraic education. The theoretical considerations is based upon Küchemann (1981), Usiskin (1995) and Ursini;Trigueros (2001), researchers who believe that variables can assume different roles: unknown, generalized number and in a functional relationship. In that scenary, the understanding of the variable concept pervades some potential ways. We were inspired at Content Analysis, described in Bardin (2004), as metodological referencial to search contexts that favour such framework. In preanalisys realized we consider the epistemology present on Diophantine Linear Equations theme as a possible way to explore the flexible uses of the variable concept. The analysis revealed that the Linear Diophantine Equations allow the acquisition of the following potentialities, expressed in Ursini and Trigueiros (2001): executing calculations and simple operations with the literal symbols; create a context of integration to the variables flexible uses; allow situating some advantages on the different uses of the variable concept.

This proposal came as a result of a Stricto Sensu research, which deals with simple problems that encourage high school students to understand Linear Programming by means of a contextualization of studied topics, as resolution of linear equations. The aim is to show to these students the range of real-world problems that can be solved using Linear Programming, with the application of methods to solve systems of linear equations and the support of mathematical softwares. The proposal presented here has not been applied in classrooms yet, but it is expected that students will be able to understand in a contextualized view where linear systems can be applied, the importance of mathematical modeling and the need of to use a mathematical software to solve real big data problems.

http://dx.doi.org/10.5902/2179460X14606This work has as a main theme the Pick’s Theorem. This theorem refers to the calculation of area of polygons with vertices at points of a flat network, such a calculation can be summarized in a simple relation between the number of points of a network, located in the interior of a polygon and the number of points of the border of the polygon that belongs to the network. Research, before, presenting your demonstration, align the central ideas of your demonstration, so that there are sufficient arguments to support it. We propose to establish a relation between this method and the well known theorem of Euler, besides presenting an arithmetical application for this theorem. The attention given to this theorem is well deserved due to its apparent simplicity and for the fact that it can awaken the interest of some students for the subject.

GEOMETRIA E TRIGONOMETRIA: POSSIBILIDADES DE UM VÍNCULO VANTAJOSO
Authors: Castaneda Alberto Martin Martinez
Published: March 2017

http://dx.doi.org/10.5902/2179460X14639The relationship between geometry and trigonometry can go far beyond the classic problem involving the two areas in basic education, which is the resolution of triangles. Possibilities of using the geometry in the service of Trigonometry, or the Trigonometry in the service of Geometry, are many. There is a tendency to separate them by rigid boundaries, affecting cooperation among the methods and techniques of both areas in solving certain mathematical problems, not necessarily limited to one area, for example, the problems posed in the Olympics. In this paper we show some of these possibilities, working with examples where from a geometric result we obtain certain trigonometric results, or, from a trigonometric result we obtain some geometric result. We also present the solution of some geometric problems using both methods.

This paper assesses Voltage unbalance study as one of power quality issues which is especially effected distribution voltages and is noteworthy. however it is possible that voltage in level of producing and transmission be balanced but this voltages in level of distribution can go out of balance and be unbalanced which is because of unbalanced systems, unequal impedances and lack of appropriate and balanced distribution of one phase loads in distribution systems occurs. In this thesis operation of steady state machine conjunction (Induction motor) under unbalanced voltage will be evaluated. Induction motors in small sizes attach as coupled and will be used instead of big sized induction motors, which is proper for improved electromagnetic systems and more efficient energy conversion mechanism in both symmetric and asymmetric states. Two coupled induction motors can have the same or different rates mechanically. This thesis will analyze coupled machinery using symmetric elements and MATLAB software. Definition of unbalance voltage is used by CVUF factor (complex voltage unbalance factor). Induction motors coupling with DC motors (direct current) is analyzed and coupling effect in electromagnetic torque in all system is studied and comparing of unbalanced voltage on standalone and coupled machines is demonstrateed. The purpose of such comparing is finding the best states in balanced and unbalanced working, also this thesis evaluates the effect of induction motors connection as coupling in energy conversion process.

Published: March 2017

In this paper a new array multiplier has been proposed, which has lower power consumption than the regular array multipliers. This technique has been applied on two conventional and leapfrog array multipliers. In the formation of 8×8 multiplier all designs proposed in this paper have been implemented using the HSPICE by the use of 180 nm TSMC technology at a supply voltage 1v. To verify the performance of the proposed structures, structures have been simulated in 130 nm & 65 nm PTM technologies. The simulation results show that applying the return technique in the array structures causes power consumption reduction and consequently PDP reduction. This improvement for 180 nm technology in the conventional array structure is 13.32 % and in the leapfrog array structure is 23.27 %. It should be noted that this technique substantially makes the number of transistors less and as a result area reduction.

Published: March 2017

In this paper, first a fuzzy controller is proposed for systems comprising two inverted pendulums placed in the same plane, where one pendulum moves along the X-axis and the other moves along the Y-axis; rules of a Fuzzy-Mamdani controller is improved by considering the behavior of an operator and a the developed expert system and by trial and error in the observation of the system’s behavior. Simulation results obtained in MATLAB are proposed and then two other intelligent methods are presented. In the second proposed method, a TSK controller is designed with Anfis training approach and its simulation results are presented. Finally, a non-fuzzy controller (linearization feedback) is used as the supervisor fuzzy controller and the simulation results are presented. At last, performance of the three controllers is compared and the results are demonstrated.

Various research provided various definition about enhanced oil recovery but generally any method to move oil recovery would be named as enhanced oil recovery.It should be noted that sometimes enhanced oil recovery means third recovery. At the other hand there is agreement about secondary recovery as part of enhanced oil recovery. as most of Iran reservoirs passed second half age and by increase of age, recovery would became very hard, specific methods should be used. Therefore the best scientific and economic method should be selected among various methods.

Meta-iodo benzyl guanidine(MIBG) is an analogue of Noradernalin transmitter. When radiolabelled with 123 I and 131I , used for scan and diagnosis Adernal’s tumor. Labeled MIBG with 131I used in therapy of Neuroblastoma , Pheochromocytoma , Carcinoidsyndome and Neuroendocrine tumors. In our continuing efforts to develop MIBG analogues with higher therapeutic efficacy, we recently evaluated the structure-activity characteristics of several analogues of MIBG. We are interested in developing HIBG analogues containing hydroxyl at the 4-postion oF HIBG.generous of the some groups to activate the aromatic ring of a drug towards electrophilic radiodiodination may have merit .The resistance of HIBG to in vivo radiodiodination and amenability to kit production make it a strong candidate for clinical evaluation as a pheochromocytoma and neuroblastoma localzing agent. Microwave assisted heating under controlled conditions has been shown to be an invaluable technology for organic chemistry and during discovery applications since it often rise yield and dramatically reduce reaction times, typically form days or hours to minutes or even seconds.Microwave Irradiation Assisted Synthesis of HIBG is started to produce 4-methoxybenzylamine. 4-methoxybenzylamine and hydriodic acid are mixed and heated for this purpose. Then under MBR condition 4-Hydroxybenzyl guanidine in sulphate form is prepared with additional Cyanamide and Sulphuric acid. After that Iodination is preformed under MBR condition and 4-Hydroxy-3-iodobenzyl guanidine sulphate formed , that can labeled with 131I and exchange to labeled 4-Hydroxy-3-iodobenzyl guanidine sulphate.
