Continuous Harmonic Analysis and Power Quality Measurements in Three-Phase Systems.
Authors: J.C. Montaño  , A. López  , J. Gutierrez  , M. Castilla  , D. Borrás  , J.C. Bravo
Published: July 2017

A virtual instrument, named Power Quality Meter, is presented for (a) measuring power consumption and harmonics in three-phase systems, under non-sinusoidal and imbalance conditions (b) detecting, classifying and organizes power disturbance events. Measurement of the power consumption follows the formulation proposed by the members of the IEEE Working Group on Nonsinusoidal Situations (1996). So, definitions are based on the analysis of functions in the frequency domain, separating the fundamental terms from the harmonic terms of the Fourier series. The virtual instrument has been developed too for monitoring and measuring power disturbances, which are automatically classified and organized in a database while they are being recorded. Software tools use the database structure to present summaries of power disturbances and locate an event by severity or time of occurrence. Records of actual measurements are included to demonstrate the versatility of the instrument.

Authors: M. Fernanda T. Moreira  , Júlio S. Martins  , João L. Afonso
Published: July 2017

This paper presents the evolution of renewable energy generation in Portugal in the last decade, and explains the legislation and incentives in existence. The paper also presents suggestions that could incentive small and medium consumers to install renewable energy power plants (namely of wind power and photovoltaic types) in their facilities. These power plants would have to accomplish present legislation regarding “reactive energy” production during peak power consumption period, and besides, would have to assure power quality levels. On the other hand, reversible energy meters should be used, so that it would be registered the consumption of energy from the energy company, or the delivery of energy to the energy company. The equipments which could implement these characteristics are briefly described.
Hedging Using Futures and Options Contracts in the Electricity Market.
Authors: Filipe Azevedo  , Zita A. Vale  , António A. Vale
Published: July 2017

Since the 80’s with the experience of Chile, the electric sector has suffered, in many counties, a process of deregulation and liberalization. In almost of the countries, that process originated the appearance of a Pool where the participants of the market trade the electrical energy on a basis of half-hour or one hour of the next day. However, like the traditional markets, the agents of electricity markets are now exposed to the volatility of market price, so far inexistent in those markets. In some countries, to face that problem and to turn the market more liquid have been introduced derivatives markets – futures and options, to negotiate products with underlying active the electrical energy. In this context, there is a need of decision-support tools that allow those agents to use derivatives markets with the objective of practicing the hedge and simultaneously increase their results. In this paper, we present a decision model that supports producers in the establishment of contracts with the objective to maximize the profit expected utility. The paper presents a group of examples of the use of this decision-support system.

Authors: J.C. Bruno  , Ll. Massagués  , A. Coronas
Published: July 2017

Distributed generation is an attractive way of producing energy, minimising transport losses and enhancing energy efficiency. Micro gas turbines in distributed generation systems add other advantages such as low emissions and fuel flexibility.
The objective of this paper is to present the experimental data of a 28 kW microturbine and a hot water waste-heat boiler at the testing facilities of CREVER in Tarragona. The purpose of this project is to determine their technical and economical viability, and their performance. The electrical efficiency measured is within the specifications provided by the manufacturer and decreases considerably with the power output. Air emissions are very low at full load and do not increase appreciably until the load is reduced below 60 – 70 % of the full load.
The results confirm that the power quality and air emissions in microturbines comply with the existing standards and that they are very competitive in comparison with other technologies in these aspects. Thus considerable market development is expected in the coming years although more research and development efforts will be needed.

Home Automation - A Step Towards Better Energy Management.
Authors: Renato Jorge Caleira Nunes
Published: July 2017

This paper argues that home automation can make a difference regarding better energy management and usage of renewable energy sources. People are sensible to the need of using energy and other resources more rationally but do very little to that end on their daily lives at home. However, home automation can come to their rescue and we give examples of the functions and the benefits that can be achieved.
The home automation market is very fragmented and many different technologies exist, which are incompatible. To overcome this problem, in this paper we advocate that interoperation should be achieved at a high level and we describe an abstraction layer that allows access to different home automation devices in an uniform and generic way, independently of their technology.
Next we address aspects of system supervision, which are essential to provide the required functions and offer an adequate control and management of the available resources. We propose an approach based on software agents, whose behavior is defined by rules. This offers an expressive means to state the users requirements and preferences.

Topology Optimizaton of Active Power Filters
Authors: Raul Monteiro  , Beatriz Borges  , Victor Anunciada
Published: July 2017

Active power filters (APF) are an important research domain, since several years ago. However the industrial use of APF is almost inexistent due to their high acquisition cost and to the absence of widely accepted criteria for usefulness. In most situations, where APF would be adopted, the plant management prefers a passive filter solution, considering simplicity, cost and rudeness. Consequently, power filtering is good for the mains network but presents a limited interest for the plant manager. Power quality in the user plant must be the main objective of active filters, instead of the suppression of harmonic content in the mains currents. This one must be a secondary objective, also achieved, but less important for the plant management, unless the contract with the power company obliges the reduction of current harmonic distortion. This approach is required to obtain the economic viability of active power filters. Consequently, the main economic objective of power filtering must be the power quality in the user plant. The power quality parameters can be evaluated as factors of cost in the design of active power filters. Another concern on the design and use of active power filters is the problem of the radio frequency conducted noise induced in the mains network. The hard switching technology, for bridge power converters, has been replaced, in our design of APF, by soft-switching technology. This paper presents a new design approach of APF based on the association of full-bridge hf soft-switching DC-DC converter with 6 cycloconverters (integral cycle control).
Magnetic Fields in Multiconductor Systems with Harmonic Currents.
Authors: M. Pineda-Sánchez  , L. Serrano-Iribarnegary
Published: July 2017

Electric and magnetic fields produced by power transmision and distribution lines are receiving strong interest due to its biological effects and interference disturbances upon electronic and computer equipment. The presence of currents with harmonic contents, generated by variable speed drives and other power electronic devices worsen the problem. The accurate evaluation of the magnteic field in the vicinity of the line must take into account the non uniform distribution of currents inside the conductors, due to skin and proximity effects. The spatial distribution of induction lines down to the ground level must be plotted, to evaluate its effects in the body of a person situated below the line This paper proposes a two step procedure for solving the problem: first, the non uniform distribution of the currents in the conductors is calculated, applying Maxwell laws. Second, the distribution of the field is obtained, using a very fast and innovative approach, based on the application of the Bidimensional Fast Fourier Transform to solve a bidimensional convolution in the domain of the spatial frequency.

Authors: J.C. Moran  , E. Granada  , J. Porteiro  , J.L. Míguez
Published: July 2017

Small scale stoves, producing heat and hot water, are suited for domestic purposes. A pilot 24 kWt fixed bed pellet stove has been developed for the study of pellet combustion in laboratory. Its design and construction was done in order to permit its maximum flexibility for the simulation of different stove configurations and operational circumstances. Temperatures, pressures, flows and gas compositions are measured and analysed. An extensive study of different load conditions is presented through the application of an experiment design technique and a subsequent statistical analysis of the results. It is shown that the main features of the plant are controlled mainly by fuel feed rate and by air-fuel equivalence ratio, being very low influenced by the temperature of the water. Very good correlation between the studied parameters have been found together with a great agreement between the predicted and the measured values.

Authors: Stellakis Nektarios , Galanis Georgios
Published: July 2017

This paper refers to a research conducted in the region of Patra, Achaia in Greece in spring 2016. Its purpose was a) the assessment of preschoolers’ narrative skills and b) the examination of its possible correlation with family sociocultural background. The participants were 32 children of the higher level of age in preschool education (5-6 years old), picked up from 2 different public kindergartens, equally separated in terms of gender and social background. Children were called to produce oral retellings of a book that had previously been read to them. Their texts were recorded and analyzed according to "The Story Pyramid Framework". The findings of the research seem to confirm that there is a strong and intense correlation between preschoolers' narrative skills and their sociocultural background. Children that come from more privileged social backgrounds produced more integrated narratives than their peers who come from less privileged family contexts, while no significant differences were observed between genders.

Modificações na cobertura vegetal do solo em bacias hidrográficas podem ocasionar alterações nas componentes hidrológicas. O objetivo do trabalho foi avaliar os processos hidrológicos sob diferentes condições de cobertura vegetal na Bacia Hidrográfica do Rio Mundaú (BHRM), Nordeste do Brasil, utilizando o modelo SWAT. Para a simulação hidrológica, foram considerados dois cenários (C1 – uso atual) e C2 (substituição de áreas agrícolas por Caatinga). Foram utilizados dados de entrada como mapa de uso e ocupação do solo, mapa digital de elevação e mapa dos tipos de solo, além de uma série de 17 anos de dados, em passo de tempo diário. A precipitação anual média da BHRM foi 1.109,7 mm, a evapotranspiração potencial anual foi 1.247,7 mm e a ascensão do aquífero raso foi de 24,94 mm por ano, em parte da bacia. O escoamento superficial anual para o cenário C1 foi igual 262,62 mm e para o cenário C2 igual a 257,49 mm. Os valores de percolação e recarga anuais foram de 302,78 e 15,14 mm para o cenário C1 e de 306,73 e 15,34 mm para o cenário C2. A evapotranspiração real anual para o cenário C1 resultou em 548,2 mm e para o cenário C2 em 549,3 mm. A mudança de uso do solo exerceu influência no regime hidrológico da Bacia do Rio Mundaú. A implantação de vegetação Caatinga em áreas agrícolas proporcionou redução no escoamento superficial. Por outro lado, processos como evapotranspiração, percolação para o aquífero raso e recarga para o aquífero profundo aumentaram.

Published: July 2017

O Manguezal é um ecossistema costeiro de transição entre ambientes terrestre e marinho, típico de regiões tropicais e subtropicais sujeito a inundação de marés, este ambiente apresenta características especificas com muita matéria orgânica e pouco oxigênio, composto de uma diversidade de especiais adaptadas.  Embora seja considerado áreas de preservação permanente este ecossistema vem ao longo dos anos sendo alvos de grandes impactos, estes na grande maioria causados por ações antrópicas, decorrentes de desmatamentos, implantação de agricultura e poluição, assim como o crescimento desordenado da expansão urbana e das atividades turísticas, com o uso inadequado que prejudica este ecossistema. Por intermédio de analises da paisagem, e técnicas de SIG (Sistema de Informação Geográficas) a presente pesquisa objetivou, diagnosticar a dinâmica espaço-temporal das áreas de mangue do litoral Sul de Alagoas, Municípios de Roteiro, Jequiá da Praia, Coruripe e Piaçabuçu. Assim Identificar áreas com quadro de fragilidade ambiental, exibido ao longo dos anos, e Identificar áreas que exibiram quadro de recuperação ambiental. Para o desenvolvimento do trabalho foram realizadas mapeamento através de imagens de satélites obtidas software Google Earth correspondente as décadas de 2004 a 2016, dos municípios envolvido, e elaborados de mapas temáticos no software livre e gratuito Quantum GIS. Em análises comparativas através da interpretação dos mapas e cálculos das áreas, foi possível diagnosticas que a maioria dos municípios apresentaram uma expansão significativa da área de mangue, aparentemente essa expansão está relacionada ao longo período de seca que essa região passa durante o ano e consequentemente diminuição do fluxo de agua doce e aumento da entrada de águas salinas nos estuários que favorece o desenvolvimento dessa vegetação.     Palavras-Chave: Análises comparativas, fragmentação e recuperação.

Published: July 2017

In semi-arid environments, the distribution of rainfall over time is decisive in emergence in a soil seed bank. The objective of this work was to evaluate the effect of rainfall events on the soil seed bank emergence of Caatinga species under high CO2 concentration. The experiment was carried out in an experimental area of Embrapa Semi-arid in a randomized complete block design, with subdivided plots. Each plot consisted of different environmental conditions (open top greenhouse with injection of 550 ppm CO2; open top greenhouse and environmental CO2; natural environment). The subplots consisted of the depth at which the seeds of Poincianella pyramidalis and Myracrodruon urundeuva were sown (superficially and buried at 0.02 m and 0.06 m depth). Seedling emergence was monitored daily after the first rains. During the experiment, weather data showed a rainfall volume of 83 mm, an average air temperature of 28.7 oC, average soil temperature of 35.4 e 34.9 oC, at depths of 0.02 and 0.06 m, respectively. Seedling emergence started 56 days after sowing and 4 days after the first rains. After 154 days of the start of the experiment, drip irrigation was performed. The greenhouse environment, regardless of the addition of CO2 or not, allowed higher emergence percentage of P. pyramidalis. The seeds of this species sowed on the soil surface only emerged when irrigation started. M. urundeuva seeds showed low germination even after irrigation.

Published: July 2017

O feijão caupi tem potencial genético para alcançar produtividades elevadas quando em cultivo irrigado, porém a deficiência de água é um dos fatores limitantes da produção de grãos. Considerando que diferentes genótipos de feijão caupi respondem de formas distintas à aplicação de água e às condições climáticas nas quais estão submetidas, objetivou-se neste trabalho, avaliar características fisiológicas e componentes de produção de feijão caupi sob diferentes lâminas de irrigação, no Submédio do Vale São Francisco. O experimento foi conduzido no campo experimental do DTCS/UNEB, Juazeiro, de julho a setembro de 2016. O delineamento experimental foi em blocos casualizados, esquema fatorial 2 x 5 (genótipos de feijão caupi x lâminas de irrigação), três repetições. Os genótipos utilizados foram BRS Acauã e Canapu; e as lâminas, determinadas com base em frações da evapotranspiração de referência estimada pela equação de Penman-Monteith. As variáveis analisadas foram: diâmetro, altura de planta, altura do primeiro ramo com vagem, massa seca da parte aérea, peso de vagem, comprimento de vagem, número de grãos por vagem, peso de cem grãos, número de vagens e número de ramos. Não houve efeito significativo de interação entre lâminas e genótipos de feijão para nenhuma das variáveis analisadas. O incremento da lâmina de irrigação proporcionou aumento no número de ramos, altura do primeiro ramo com vagem e massa seca da parte aérea dos genótipos de feijão caupi. Para a época de condução do experimento, o genótipo Canapu se destacou, quanto a componentes básicos relacionados à produtividade de grãos.

Aumentos na temperatura ambiente podem influenciar de forma significativa o processo de germinação de diversas espécies vegetais. Podem interferir diretamente em atividades fisiológicas, bioquímicas entre outras, alterando desta forma a máxima capacidade das sementes em ativar a emergência das plântulas, bem como a formação morfológica das plantas. Nesse sentido, o objetivo desse trabalho foi simular em câmaras de crescimento o efeito de diferentes temperaturas na germinação de três cultivares de milho: BRS Assum preto, BRS011 e BRS033 Asa Branca. O experimento foi implantado a partir da utilização dos tratamentos formados por três temperaturas controladas: 20º, 30º e 40ºC. As variáveis analisadas foram percentuais de germinação; índice de velocidade de germinação; tempo médio de germinação; frequência de germinação; altura das plântulas; diâmetro do caule; número de folhas; clorofila A, B e total; massa fresca e seca do caule, folha e raiz. Para a estatística foi aplicado o teste de Tukey a 5%, nas variáveis quando significativas. A faixa de temperatura de 30ºC é a ideal para a germinação e desenvolvimento inicial de mudas de milho. As variedades estudadas não apresentam diferenças significativas para a produção de massa seca, exceto a das raízes, bem como para as variáveis biométricas estudadas. Não há diferenças entre as variedades na produção de clorofilas. A temperatura de 30ºC foi a que apresentou o maior índice de clorofila A e total; massa seca do caule e das folhas, assim como das variáveis biométricas.

Published: July 2017

Neste estudo comparam-se os valores do limite de liquidez, LL, obtidos pelo método do Cone de Penetração, LLp, com os valores de LL obtidos pelos métodos de Casagrande, LLc, medidos, por diferentes operadores, em amostras de solos argilosos de alta e baixa plasticidade. O método do Cone de Penetração considerado segue a norma britânica (penetração de 20 mm). Os resultados experimentais mostram que as variações entre os dois métodos dependem da plasticidade e mineralogia do solo cohesivo ensaiado. Os resultados obtidos para argilas naturais, essencialmente constituídas de caulinitas, com valores de LLc entre 14% e 98%, indicam que LLp é geralmente maior 2,7 % que LLc. Entretanto, existe maior dispersão entre os valores de LLc e LLp medidos para as misturas de bentonita e areia fina, com valores de LLc > 100%, que apresentam LLc igual a aproximadamente 1,2 LLp.

Authors: Румянцев И.А. , Шебеста А.А.
Published: July 2017

Цель работы состояла в оценке влияния разгрузки подземных вод на состав морской воды и донных отложений в Финском заливе. Рассмотрены собственные данные и материалы ряда геологических организаций (ОАО Севзапгеология, ВСЕГЕИ и ВНИИ Океангеология), относящиеся к побережью Курортного района Санкт-Петербурга и к Невской губе. Пробы поверхностных вод и донных отложений проанализированы в лаборатории геоэкологического мониторинга СПбГУ на содержание металлов методом атомно-абсорбционной спектрометрии и нефтепродуктов методом ИК-спектрометрии. Пробы подземных вод проанализированы в аккредитованных лабораториях ОАО «Севзапгеология». Отмечены повышенные концентрации меди, бария, железа, алюминия, свинца, никеля в воде и донных отложениях Невской губы, а также прибрежной части Курортного района. Проведено сравнение составов морских вод в районе кратерообразных донных образований (покмарков) в Копорской губе и подземных вод вендского водоносного горизонта. Результаты свидетельствуют о существовании в Финском заливе участков, подверженных существенному влиянию сосредоточенной подводной разгрузки подземных вод.
DESIGN AND EVALUATION OF COLON SPECIFIC DELIVERY OF BUDESONIDE CORE IN COAT MATRIX TABLET USED IN LOCAL ULCERATIVE COLITIS
Authors: M Mallikarjuna Gouda , A Ramakrishna Shabaraya
Published: July 2017

In the present investigation planned to study the less explored sterculia gum as matrix carrier of Budesonide to colon. Developed the formulations from B1 to B4 contains alone sterculia gum and its proportion increased gradually in the formulation. The formulations B5 to B10 contain the sterculia gum in combination with Eudragit S 100 and the hydrophilic, hydrophobic polymer. The budesonide core in coat matrix tablets was prepared by direct compression method. The powder bed of the formulations is evaluated for pre compressional characteristics like bulk density, tapped density, compressibility index and angle of repose. The compressed budesonide core in coat matrix tablets were evaluated for post compressional characteristics like thickness, diameter, hardness, disintegration, friability and to understand the drug release pattern and to correlate the in vivo condition, the in vitro dissolution performed in three different gastro intestinal pH at 1.2, pH 7.4 and pH 6.8 with and without 4% rat cecal content. The in vitro dissolution results of formulations ascertain that sterculia gum alone in formulation uncontrolled the drug release in first 5 hrs and carried lesser amount of drug to colon. The formulations B8 in the first 5 hours released 4.3% and carried the larger amount of drug to colon and in absence of rat cecal content released 90% and in presences of 4% rat cecal content released 99% of drug, indicating the sterculia gum undergoes enzymatic degradation and this formulation is considered as potential in targeting the budesonide to colon in the local ulcerative colitis.
Women Image in “Miss Jinjing Belanja Sampai Mati” Book
Authors: Stellarosa Yolanda
Published: July 2017

Book of “Miss Jinjing Belanja Sampai Mati” or “Miss Carry Shops to Dies” explains about lifestyle, shopping world and woman leading to the emergence of Miss Jinjing’s icon for the spirit of shopaholic or shopping lovers. This research aims to reveal how Miss Jinjing Belanja Sampai Mati’s text book presents and reflects women image using of simulation imaginary model of Jean Baudrillard, and how the media is used as a means of capitalism legitimacy. This research uses a qualitative method. The research output concludes that women are as consumptive figures, connoisseur, and shopping lover. By having seen on simulation imaginary model of Jean Baudrillard, the form of image starts from representation, ideology, and simulation phases reflected in Miss Jinjing’s text book;  while the simulacra leading to hyperreality happens when the readers are brought into text persuasion. Media’s work in forming the image of consumptive women, shopping lovers and shopaholic is a reflection of capitalism identity. Media presents an excessive reality in its writing on lifestyle and shopping world for women to control and dominate so that women are able to be voluntary and even do in many ways to achieve hyperreality formed by capitalism system. Woman image established in this case, is no longer another thing than as commodity which is expected to be sold out to advertisers.
THE POETICS OF TRAUMA AND HOPE IN WOUNDED WATER BY ANABEL TORRES
Authors: Castro Lee Cecilia
Published: July 2017

Wounded Water / Agua herida (Bogotá 2004) is a bilingual book of poetry by contemporary Colombian poet Anabel Torres (1948). This book offers a poetic encounter with the trauma or “minute personal shocks» Paul Valery cites when referring to Baudelaire’s poetry. Torres writes of her everyday existence as a woman, as a poet, and as an emigrant living in Europe for the last two decades or more. I contend that Wounded Water/ Agua herida is poetry of survival, similar to what Gregory Orr defines as “transformational lyric poetry”. The semantic field of water in Torres’s poetry conceptualizes a broad spectrum from birth, death, and rebirth.
EL SUTIL REGODEO DE LA DECADENCIA. DINÁMICAs URBANAS, FRONTERAS PERMEABLES Y TIEMPO SUSPENDIDO EN EL MUSEO DE CERA DE JORGE EDWARDS
Authors: Gatti Giuseppe
Published: July 2017

The purpose of the present article consists of proposing a different interprtetation of the novel El museo de cera, which the Chilean writer Jorge Edwards published in 1981: we will concentrate not only in the habitual critical interpretation that confirms the lucid satirical sentence of the reactionary Chilean thought, but we will approach the plot from a perspective that demonstrates the relation between individual and collective time. At the same time, we analyze the representation of the decadence of a social and political structure, by connecting the fictional images from Edwards with the representations of the decline presented in the Austro-Hungarian narrative of the beginning of the 20th century. Finally, we examine the dynamics of osmosis between the two geosocial contexts described in the fiction demonstrating the permeability of sectors by all appearances opposite.
HÉROE, HISTORIA Y FARSA EN LA CARROZA DE BOLÍVAR DE EVELIO ROSERO
Authors: Vanegas Orfa Kelita
Published: July 2017

The transgressive artistic intention in the reshaping of historical events that have given form to the Colombian nation, along with the delusive meaning obtained by founding heroes are evident again in the novel La carroza de Bolívar (2012) by Evelio Rosero. In it, a complex thematic and stylistic interweaving animates the painful memories of Independence struggles, where the carnivalesque and phony deeds of people structure an ample framework of writings, rewritings, versions, and diversions that pretend to dismantle the historical, political, and sociocultural ideologies of Colombians about the beginning of the Nation.

Purpose: i) To determine the relationship between the cardiac biomarkers ST2 and NT-proBNP with ejection fraction (EF)
in heart failure (HF) patients. ii) Assess whether a superiority existed between the aforementioned cardiac markers in
diagnosing the HF with reduced EF. iii) Determine the efficacy of both biomarkers in predicting a 30-day cardiovascular
event and rehospitalization in patients with HF with reduced EF iv) To assess the influence of age, gender, BMI, anaemia
and renal failure on the ST2 and NT-proBNP levels. Design and Methods: A prospective double-blind study was conducted
to obtain data from a sample of 64 cardiology patients. A blood sample was collected to test for ST2 and NT-proBNP. An
echocardiogram (to obtain EF value), electrocardiogram and questionnaire were also obtained. Results: Of the 64 patients
enrolled, 59.4% of the population had an EF less than 40%. At the end of the 30- day period, 7 patients were warded, 37
were not warded, one died and 17 were non respondent. Both biomarkers were efficacious at diagnosing HF with a reduced
EF. However, neither of them were efficacious in predicting 30-day rehospitalization. The mean NT-proBNP values being:
not rehospitalized (2114.7486) and 30 day rehospitalization (1008.42860) and the mean ST2 values being: not
rehospitalized (336.1975), and 30-day rehospitalization. (281.9657). Conclusion: Neither ST2 or NT-proBNP was
efficacious in predicting the short- term prognosis in HF with reduced EF. Both however were successful at confirming the
diagnosis of HF in HF patients with reduced EF.
