Authors: Deniz Alic Ural  , Kerem Ural
Published: July 2017

Objetivo. Determinar si la suplementación a corto plazo en 2 niveles (1 o 2 g/kg) de clinoptilolita (CLNP) en el calostro de terneros lecheros tiene algún efecto sobre la ganancia de peso total (TWG) y la ganancia media diaria de peso (MDWG). Materiales y métodos. Se asignó un total de 24 terneros clínicamente sanos sin diarrea en un subconjunto de los tres grupos principales de terneros que fueron estudiados: grupo I (n = 8) recibieron calostro con CLNP a razón de 1 g/kg inmediatamente después del parto a las 12 y 24 horas , para un total de 2 dosis. Grupo II consistió de terneros (n = 8) que recibieron calostro con CLNP a razón de 2 kg / dentro del mismo intervalo que el primer grupo experimental. El último grupo III, que sirvió como control, recibió únicamente calostro. Resultados. Grupo tuvo un efecto significativo sobre el peso (kg) de terneros Holstein [GTT (media±DE) - Control: 12.66 ± 0.349, el grupo I: 14.73 ± 0.414, el grupo II: 14.19±0.468, p<0.01; mdwg (media±DE) - Control: 0.338±0.0155, el grupo I: 0.396±0.0189, grupo II: 0.397 ± 0.0196, p<0.05]. Hubo una diferencia significativa para TWG (p<0.01) y mdwg (p<0.05) entre el grupo control y ambos grupos de tratamiento CLNP. Conclusiones. Los resultados mostraron que la adición de los dos niveles de clinoptilolita a través del calostro mejoró TWG y MDWG en terneros recién nacidos sin tener ningún efecto adverso observable.

Authors: Molina D Víctor , García G José
Published: July 2017

Objetivo. Determinar factores predictivos de intubación de vía aérea y su valor pronóstico, de acuerdo a la morfología del cráneo en caninos. Materiales y métodos. Se realizó un estudio descriptivo, observacional en dos clínicas veterinarias en la ciudad de Medellín, Colombia. Para este estudio 74 perros se evaluaron al azar. Todos se sometieron a factores predictivos como Mallampati, Patil-Aldreti, Cormack-Lehane y la distancia esternón mentoniana, de acuerdo a la morfología del cráneo. Los datos fueron evaluados mediante prueba de Tukey con una p≤0.05 para morfología del cráneo y las escalas de predicción; además, del análisis de componentes principales como predictivo para cada escala según raza. Resultados. En este estudio se encontró una diferencia estadística significativa para Mallampati entre caninos braquicéfalos, dolicocefálicos y mesocefálicos (p=0.00). Los braquicefálicos tuvieron intubación difícil. Igualmente, se presentaron diferencia en Cormack-Lehane entre braquicéfalos y los otros dos grupos, con difícil intubación. Patil-Aldreti demostró diferencias entre braquicefálicos y los demás, con dificultad moderada. La distancia esternomentoniana, no mostró ninguna divergencia para cualquiera de los tres grupos. La evaluación del predictor de intubación encontró que 13.51% de los perros, tuvieron intubación difícil, 37.83% con dificultad moderada y 47.29% mostraron dificultad ligera para la intubación. Los intentos de intubación promedio fueron 1.83 y el tiempo promedio de intubación fue de 123.43 segundos. La evaluación estadística de componentes principales determinó que la raza Bulldog, se predice por Mallampati y Patil-Aldreti mientras Pinscher es predicha por Cormack Lehane, mientras que las razas cruzadas, no son influidas por un factor de predicción. Conclusiones. Los caninos de tipo braquicefálicos son los que presentan mayor dificultad de intubación y Mallampati es su principal factor predictivo.

Published: July 2017

ABSTRACTObjective. Improve the nutritional value of mechanized sugarcane residues inoculating the fungus Fomes sp. EUM1. Materials and methods. The fungus Fomes was inoculated according to a 0, 0.1, 0.2, and 0.3% (w/v) treatment and incubated at a temperature of 35°C for 7, 10 and 13 days. It was obtained DM, OM, CP, ash, NDF and ADF and the effective degradation of DM, NDF and ADF, with an experimental factorial design of 3X3 and a completely randomized design. The factors were growing days in an Erlenmeyer flask (7, 10, and 13) and inoculum percentage (0.1, 0.2 and 0.3). The data were analyzed with the SAS statistical package. Results. Statistical significance was found in the interaction of the fungus growing days by percentage of inoculum, in the variables: DM, CP and pH. The NDF and ADF factor differed in the percentage of inoculum. Effective degradation showed significant for the same type of interaction in all the variables studied. Conclusions. The inoculation of the fungus increased ADF degradation by only 0.2% of the inoculum percentage, without any effect on effective degradation due to the use of soluble fractions at the beginning of the incubation. It is considered that the degradation occurs in stages that are important to consider for determining treatments to maximize the beneficial effects of the fungus in terms of ruminant nutrition.
Patient-Driven Innovation for Mobile Mental Health Technology: Case Report of Symptom Tracking in Schizophrenia
Authors: Torous John , Roux Spencer
Published: July 2017

This patient perspective piece presents an important case at the intersection of mobile health technology, mental health, and innovation. The potential of digital technologies to advance mental health is well known, although the challenges are being increasingly recognized. Making mobile health work for mental health will require broad collaborations. We already know that those who experience mental illness are excited by the potential technology, with many actively engaged in research, fundraising, advocacy, and entrepreneurial ventures. But we don’t always hear their voice as often as others. There is a clear advantage for their voice to be heard: so we can all learn from their experiences at the direct intersection of mental health and technology innovation. The case is cowritten with an individual with schizophrenia, who openly shares his name and personal experience with mental health technology in order to educate and inspire others. This paper is the first in JMIR Mental Health’s patient perspective series, and we welcome future contributions from those with lived experience.
Approaches to Taxonomic Studies of Actinomycetes Isolated from Historic and Contemporary Materials
Authors: Blyskal Barbara , Lenart-Borod Anna , Borod Piotr
Published: July 2017

Microorganisms may cause the almost complete degradation of a material structure,even though symptoms of drastic microbial damage may not be apparent macroscopically. Due to their enzymatic activities and outstanding adaptation abilities to various environmental conditions, actinomycetes constitute a particular threat to a variety of materials. They are able to use, and subsequently degrade any substrate, whether this happens in a matter of days, weeks or years. Given the frequency of occurrence and a number of features that enable Streptomyces to growth on materials, more studies should be undertaken on methods allowing for their proper and rapid identification. Taxonomic studies gain particular importance in the case of damaged valuable historic materials. This paper focuses on identification of actinomycetes isolated from various historic and contemporary materials, including textiles, parchment and ceramics. Strengths and weaknesses of approaches that have been chosen for actinomycetes taxonomic studies are described.
Da experiência psicológica a uma noção do contar em Grande Sertão Veredas: provocações literárias para pensar a subjetivação como processo coletivo a partir da narratividade
Authors: Codeço Dias Renata
Published: July 2017

Este artigo utiliza a obra de Guimarães Rosa enquanto revelador de conceitos como o de experiência, narração e memória a fim de questionar e provocar o atual estatuto das noções homônimas presentes na psicologia. A partir de passagens do livro “Grande Sertão: Veredas”, procuramos levar a pensar o processo de subjetivação como engendrado pela narratividade, sendo assim um processo coletivo que atravessa as dicotomias presentes nas correntes de pensamento clássicos da psicologia e da semiologia contemporânea.Através de um processo de criação a que chamamos de “ouvinte invisível”, Rosa transpõe a psicologização da experiência revelando o surgimento de “eus” e “mundos” advindos do próprio contar. A narratividade revelada pela criação literária provoca a possibilidade de uma mudança de paradigma no estatuto da experiência em psicologia. O contar une literatura e pensamento psicológico em uma travessia de todos.
Sobre ações de Insistência e outros nós ou como rasurar identidade e cidade: construindo um textotrama em Belém-Pará-Amazônia

Published: July 2017

Partindo da compreensão de que o domínio de ferramentas de criação discursiva que instituem categorias ordenadoras de visões de mundo se trata de uma estratégia fundamental de sobrevivência / permanência nos territórios criados / disputados; e fazendo alusão à técnica de tecedura manual, elaboramos este texto enquanto um textotrama na qual buscamos agenciar fios discursivos (conjuntos de falas e práticas) dos principais sujeitos que nomeiam e rasuram a categoria-cidade Belém do Pará, bem como três de suas principais identidades hegemonicamente instituídas: quilombola, indígena e ribeirinha, as quais são, nos discursos dominantes, consideradas “outras” que diferem daquela(s) que identifica(m) o “cidadão belenense”. Cabe ressaltar que o ato de alinhavar-cartografar diferentes discursos / falas e práticas dos principais sujeitos (des)constituidores destas categorias é já tramá-los com meus próprios discursos, e é o enlace destes que compõem agenciamentos, aqui denominados enosamentos.
Histórias que navegam pelo rio: narrativas de populações ribeirinhas
Authors: Domingues Adriana Rodrigues , Nobre Letícia Nicoluci , Regina Nathany Dos Santos
Published: July 2017

Este artigo relata as experiências de um projeto de história oral desenvolvido em comunidades ribeirinhas que vivem à margem do Rio Solimões no Estado do Amazonas e discute a importância da narrativa e da memória individual e coletiva para os moradores locais. O texto apresenta trechos extraídos de um livreto publicado em 2014 que relata as histórias dos moradores mais antigos de 5 comunidades contempladas pelo projeto, abordando as formas e os desafios de viver na floresta amazônica. A experiência narrativa é aqui considerada como uma tentativa de evitar um processo de esquecimento das histórias dessas comunidades, visando a reconstrução e ressignificação de fatos do passado, mas também a valorização da memória coletiva como forma de enraizamento e produção do comum frente às formas de dominação tecnológica e expropriação da cultura local.
Rastros do Sem-Nome que o Diga
Authors: Modernidade e Cultura/IPPUR-UFRJ Grupo de Pesquisa
Published: July 2017

RASTROS DO SEM-NOME QUE O DIGA é um dos ENSAIOS CAPIROTOS que constituem o VOLUME II do TOMO VIII “DO EXPERIENCIAR”, do MANUAL TEÓRICO-PRÁTICO DE ARTES DRÁSTICAS. Enquanto tal, em sentido geral problematiza a ideia de experiência em seus termos usuais no senso comum e no chamado domínio científico. Dialogando implícita ou explicitamente, de modo crítico ou em sintonia, com abordagens emblemáticas sobre o tema  _como as de Walter Benjamin, Gilles Deleuze, Félix Guattari, Jacques Derrida, Hans-Georg Gadamer, Ernst Cassirer, Martin Jay_, apresenta três escrituras rastro distintas, ainda que absolutamente imbricadas, que argumentam de modo fragmentário, não linear e descontínuo sobre ideações que associam ao termo ‘experiência’ enquanto agenciamento coletivo de enunciação. São escrituras (escritos, imagens) que, mais do que predicar qualquer coisa, buscam provocar múltiplas linhas de fuga a se conectar ou disjuntar na singularidade de cada leitura. Em pertinência ao Manual em que se insere, o ensaio constitui-se como um discurso drástico, ou seja, como um dizer que escapa a qualquer plano de legitimação ou valoração determinada heteronomamente pelo poder instituído ou praticado. A esses poderes, ou às suas concernentes razões apolíneas, portanto, não se constitui como um ensaio lícito. Seria algo inútil, não mais do que junção aleatória de rabiscos, garatujas, palavras, narrativas sem sentido ou lógica. Paradoxalmente, os autores, reiterando o espírito do Manual, o valoram como desútil, como dizer que não afirma e nem opera premido por quaisquer exigências externas de eficiência _prazos, urgências, medidas, precisão_, mas que prima pelas afectações poiéticas que possa suscitar. Trata-se de um discurso que se positiva na pura superfície de seu expressar-se e no tempo de um presente que nunca se presentifica, enquanto evidenciação de devires sem início ou fim ou trajetória ou direção fixas. Como apontado, compõe-se de três escrituras rastro que se tramam rizomaticamente: RASTRO SETE-PELE: DESINVENTAR PROFUNDEZAS, RASTRO BELZABU: INVENTAR ESTRATÉGIAS SUPERFÍCIES e RASTRO DIANHO: DEPOIS DO HORIZONTE AZUL OU PARA O INFINITO E ALÉM, AQUI. O primeiro problematiza direta e explicitamente a palavra experiência no ensejo (inviável) de dizê-la cabalmente de modo não-ontológico, aliás, pretensão utópica subversiva de todo o Volume II do Manual. Rastro Belzabu procura imbricar os verbos experienciar, territorializar, agenciar e narrar, borrando essa trama por meio de imaginações suscitadas pelas palavras labirinto e deserto. O último, Rastro Dianho, é uma redobra sobre si mesmo dos rastros agenciados, sob a forma aparente de um testemunho. Cada uma dessas escrituras, montada como coleção fragmentária de dizeres, não se pretende explanação apodítica sobre qualquer coisa, mas sim provocar aos leitores, em cada ato de leitura, uma experiência enquanto devir ler-agenciar-narrar sobre o experienciar enquanto devir agenciar-narrar.

William Blake’s poem, ‘The Sick Rose,” which deals with the opposition against pink versus worm and serves to denounce corruption, is passed on to the installation entitled ‘Sick Rose”, created by David Burrows and exhibited at the Cloud & Vision Exhibition 2005 , In London. The accusations of Blake’s time are transposed into those of the twentieth century and the contemporary recovery of Blake’s work in Brazil gives us clues that the poet’s radical denunciation of corruption is still valid.--- DOI: http://dx.doi.org/10.22409/cadletrasuff.2017n54a514

Authors: Ferk-Savec Vesna , Urankar Bernarda , Aksela Maija , Devetak Iztok
Published: July 2017

The main purpose of this paper is to present Slovenian and Finnish prospective chemistry teachers? perceptions of their future profession, especially with regard to their understanding of the role of the triple nature of chemical concepts (macro, submicro and symbolic) and their representations in chemistry learning. A total of 19 prospective teachers (10 Slovenian, 9 Finnish) at master?s level in chemical education participated in the research. The prospective teachers? opinions were gathered using an electronic questionnaire comprising six open-ended questions. The study revealed many parallels between Slovenian and Finnish prospective chemistry teachers? perceptions of their future profession and their understanding of the role of the triple nature of chemical concepts, especially particle representations, in chemistry learning. The majority of the prospective teachers from both countries believe that personal characteristics are the most important attribute of a successful chemistry teacher. Thus, they highly value teachers? enthusiasm for teaching and the use of contemporary teaching approaches in chemistry. The prospective teachers displayed an adequate understanding of the role of the triple nature of chemical concepts (i.e., particle representations) in the planning and implementation of a specific chemistry lesson.

Published: July 2017

Background/Aim. Dental status and oral hygiene habits are poor in young population living in deprived socioeconomic conditions. The aim of this research was to ascertain oral hygiene habits in adolescents attending high schools in urban area, determine the incidence of tooth loss at the age of 15?16 years and the gender difference. Methods. The epidemiological cross-sectional study included 234 randomly selected high school students. The research instruments were questionnaire (focusing on socio-demographic characteristics, habits, attitudes and behavior related to general and oral health) and clinical examination (tooth loss, normative need for prosthodontics restorations and presence of restorations). Results. Gender-related data comparison revealed that 32.5% of girls and 8.1% of boys had at least one tooth extracted (p < 0.05). Also, 56.2% of girls and 75.7% of boys brushed their teeth twice a day. Caries complications were identified as the indication for tooth extraction in 82.8% of participants. The data analysis confirmed the correlation between gender and tooth loss as well as treatment needs. Tooth loss was correlated with oral hygiene habits and reasons for dental visits. Treatment need was also affected by the reasons for tooth extraction and the absence of adequate prosthodontics therapy (p < 0.05). Conclusion. Sociodemographic conditions significantly influenced the number of participants with extracted teeth. A prosthodontic treatment need was influenced by the reasons for tooth extraction, adolescents? knowledge about the importance of adequate treatment and previous unpleasant experience.

Authors: Karaman E , Yazici AR , Ozgunaltay G , Ustunkol I , Berber A
Published: July 2017

Objective:

To compare the 24-month clinical performance of two different resin composites in class II slot restorations.

Methods and Materials:

Thirty-seven patients having at least two approximal carious lesions were enrolled in the study. A total of 116 teeth (58 pairs) were restored with either a silorane-based composite (Filtek Silorane) and its self-etch adhesive (Silorane Adhesive System, 3M ESPE) or a methacrylate-based packable resin composite (X-tra Fil) and its self-etch adhesive (Futurabond NR, VOCO GmbH) according to the toss of a coin. The restorations were evaluated at baseline and at six-, 12-, and 24-month recalls by two calibrated examiners according to the modified US Public Health Service criteria. The comparison of the two restorative materials for each category was performed with the Pearson chi-square test. Within group differences of the materials at different recall times were compared using the Cochran Q and Friedman tests. Bonferroni-adjusted McNemar test was used when significant difference was found (p<0.05).

Results:

After 24 months, no statistically significant differences were found between the two restorative materials for the criteria evaluated.

Conclusions:

Both silorane- and methacrylate-based resin composites showed clinically acceptable performance in class II slot restorations after 24 months.

Published: July 2017

The present work was aimed to form the baseline data of normal morphological and histological structure features of liver in migratory starling (Sturnus vulgaris). Anatomically, the starling liver bird was dark red -brown in colour and located in the cranial third of the abdominal cavity and consisted of undivided lobes (left and right). The liver right lobe was larger than the left. Histological examination revealed that the liver parenchyma was covered by a connective tissue capsule which appears to be thicker in the rim of liver lobes than other area in the liver lobe. Liver parenchyma was arranged in an unlimited hepatic lobules, which composed of polygonal hepatocytes organized as irregular, radial interconnecting cords or laminae of one or two cells thickness around a central vein and separated by blood sinusoids. In the boundary of each lobule showed a portal area which consists of a branch of hepatic artery; one or more branches of hepatic vein and one to four branches of the bile duct which lining by cuboidal cells that characterized by their empty non-staining cytoplasm. The histochemical observation by using PAS staining in the current study revealed that the glycogen granules arranged close to the central vein and in the rim of liver lobules.The present work was aimed to form the baseline data of normal morphological and histological structure features of liver in migratory starling (Sturnus vulgaris).

Play-based Learning and Intentional Teaching: Forever Different?
Authors: Edwards Susan
Published: July 2017

PLAY-BASED LEARNING IS a cornerstone of early childhood education provision. Play provides opportunities for young children to explore ideas, experiment with materials and express new understandings. Play can be solitary, quiet and reflective. Play can also be social, active and engaging. While play is commonly understood as the basis for learning in early childhood education, this is not always the situation in all settings. Cultural variations in learning and play suggest that social interactions and observational learning also create powerful pedagogical learning environments for young children. International and national research highlights the value of sustained and reflective interactions between children and educators in promoting children's learning. Increasingly, the notion of quality in play-based pedagogy invites educators to integrate traditional beliefs about play with new insights into the role of social interactions, modelling and relationships in young children's learning.

Overseas, the movement towards quality play-based pedagogy reflects debate and policy initiatives captured by the notion of intentional teaching. In Australia, the Early Years Learning Framework makes explicit reference to intentional teaching. Intentional teaching arguably engages educators and children in shared thinking and problem solving to build the learning outcomes of young children. However, the pedagogical relationship between play-based learning and intentional teaching remains difficult to conceptualise. This is because the value placed on the exploratory potential of play-based learning can appear to be at odds with the role of intentional teaching in promoting knowledge development. This paper reaches beyond binary constructs of play and intentional teaching, and invites consideration of a new Pedagogical Play-framework for inspiring pedagogical and curriculum innovation in the early years.

This paper was a keynote address at the 2016 Early Childhood Australia National Conference addressing the theme Inspire-be inspired to reach beyond quality.

The number of children attending child care is increasing, thus this setting is strategically placed to establish positive eating habits. This qualitative study sought to understand the needs of Australian early childhood education and care staff in relation to the provision of a healthy eating environment. Key stakeholders formed a consultancy group to provide feedback and advice. The study was underpinned by the Spiral Action Research model. Analysis of 48 in-depth interviews identified the following themes: healthy eating activities, resources, nutrition training, attitudes towards healthy eating and the proposed intervention, and barriers to healthy eating. Participants were open to using an online repository of nutrition resources and information wrapped in support. This formative data informed the development of a ‘best practice’ website including discussion boards intended to foster an online ‘community of practice’.

VALID AND RELIABLE TOOLS have recently been developed to accurately detect early signs of Autism Spectrum Disorder (ASD) and other developmental challenges in children as young as 12 months of age. Translation of research findings to practice and policy through routine implementation of evidence-based tools in the community, particularly early childhood education and childcare settings, is limited. This study establishes that the interrater reliability (IRR) of early childhood educators in administering the Social Attention and Communication Surveillance System (SACS-R) is very high ( k = 0.909). This paper reports the results of the first step in the Right Kids, Right Time, Right Services project—a prospective cohort study that aims to implement and evaluate routine developmental surveillance for early signs of social and communication challenges in young children in childcare settings.
Understanding and Supporting Young Writers: Opening the School Gate
Authors: Mackenzie Noella M. , Petriwskyj Anne
Published: July 2017

LEARNING TO WRITE IS critical to becoming literate. In this paper we examine continuities and discontinuities in pedagogical approaches to writing across preschools and schools. Qualitative approaches to data collection and analysis were applied. Findings suggest that preschool teachers rarely introduce children to traditional or digital forms of writing, while schools seem to expect even their youngest students to write using letters and words and conventional written text structures. This suggests that there is a metaphorical ‘gate’ between the two settings with approaches to early writing based on which side of the gate the children are, rather than where they are on their personal writing learning journey. The authors provide a rationale for opening this gate in order to support young writers as they transition from prior-to-school settings to school.
Book Collections in Long Day Care: Do they Reflect Racial Diversity?
Authors: Adam Helen , Barratt-Pugh Caroline , Haig Yvonne
Published: July 2017

CHILDREN'S LITERATURE IS IMPORTANT because it nurtures emotional, social, creative and cognitive development, and gives children opportunities to appreciate and respond to diversity. In particular, literature that portrays racial and cultural diversity is a powerful means of promoting understanding of others while affirming individual identity. However, the limited number of studies about the nature and use of literature that reflects diversity in early childhood settings prompted this study, which investigates the nature of book collections in five long day care centres in the metropolitan region of Perth, Western Australia, with a specific focus on the extent to which they reflect racial diversity. Qualitative data was drawn from an audit of the children's book collections (2377 books) across each of the five centres. The findings revealed a lack of representation of racial diversity in those collections and where racial diversity was portrayed, non-dominant cultures were commonly misrepresented through stereotypical images often portraying outdated perspectives.

Finite Element Analysis of Electrical Machines Used in Two-Frequency Indirect Temperature Rise Tests
Authors: E. Schlemmer
Published: July 2017

Heat  runs  of  large  asynchronous  machines (AM)  are  hardly  ever  conducted  under  load  but  with synthetic approaches, such as the two-frequency  method. In  its  classical  variant,  the  AM’s  stator  is  fed  by  two series-connected  synchronous  machines  (SM)  with  dif-ferent  frequencies,  for  instance  50  and  40  Hz.  While  the 50  Hz  voltage  determines  the  AM’s  flux,  the  40  Hz source  causes  an  AM  stator  current  close  to  its  rated value. Together, voltage and  current  yield approximately full  load  losses  in  the  AM  without  mechanical  loading. For  designing  the  amortisseurs  of  the  synchronous  gene-rators,  damper  losses  were  calculated  using  the  Finite Element  method.  Additionally,  calculated  full  load  AM losses  were  compared  against  their  respective  values  for the two-frequency method.

Published: July 2017

A DC reactor type fault current limiter (FCL) in series with a downstream circuit breaker can be a solution to control fault current levels in electrical distribution systems. In order to integrate the DC reactor type FCL in to power grid, the performance of the DC reactor FCL should be studied. In this paper, short circuit analysis, based on the electromagnetic transient program (EMTP), has been used to investigate the behavior of the DC reactor type FCL installed in an electrical distribution grid. System studies show that the DC reactor type FCL can not only limit the fault current to an acceptable value, but also can mitigate the voltage sag. The Transient Recovery Voltage (TRV) could be damped in the presence of the DC reactor type FCL during fault clearing period, too

In remote areas, electricity could still be available if  stand-alone  renewable  electricity  power  sources  are  used  .One  of  the  most  promising  applications  of  renewable  energy  technology  is  the  installation  of  hybrid  energy  systems,  where  the  cost  of  grid  extension  is  prohibitive  and  the  price  of  fuel  increases drastically with the remoteness of the location. It has been demonstrated that hybrid energy systems can significantly reduce  the  total  life  cycle  cost  of  stand-alone  power  supply,  while  at  the  same  time  providing  a  more  reliable  supply  of  electricity  .Due  to  the  high  nonlinearity  characterizing  the  PV-Wind hybrid system it would be impractical to develop rigorous mathematical  model  and  at  the  same  time  obtain  a  simple  and  effective controller.In this paper, a control system, which includes either the Neural Network  Controller  (NNC)  or  the  Fuzzy  Logic.  Controller  (FLC)  controller  is  developed  for  achieving  the  coordination  between  the  components  of  a  PV-Wind  hybrid  system  as  well  as  control  the  energy  flows.  The  performance  of  the  system  is  evaluated  by  comparing  the  performance  of  the  system  using  the  NNC  and  the  FLC.  Also,  this  work  presents  a  complete  mathematical  modeling  and  MATLAB  simulink  model  for  the  different components of the hybrid system.

This paper proposes a high power fuel cell simulator built by means of an active power rectifier that works with unity power factor in the grid side. The Unity Power Factor Rectifier (UPFR) is controlled by a digital processor to produce in the dc terminals the electrical behaviour of commercial high power fuel cells (FC). The control used in the paper is based in the FC model developed in the paper. The UPFR control algorithms are explained in the paper and some simulated results are presented in the paper. The simulated results demonstrate the behaviour of the proposed system.

Published: July 2017

This paper evaluates methods for voltage sag source detection, which are based either on energy, current or impedance criteria. It is shown that some methods known from the literature do not work well, particularly in cases of asymmetrical voltage sags. Furthermore, some methods require measurements of instantaneous values, which is not always feasible. Therefore, symmetrical component transformation is applied, whereas only positive-sequence components are used. All the discussed methods were tested by applying extensive simulations and field tests. The obtained results show that all methods which are based on positive-sequence components are highly effective also in cases of asymmetrical voltage sags.

Eficiencia en los mercados financieros y predicción de precios de los activos. Efficiency in financial markets and forecast of asset prices
Authors: Quiroga Eduardo
Published: July 2017

El presente trabajo tiene por objeto analizar la eficiencia en los mercados financieros, para lo cual examina las posturas de los galardonados con el Premio Nobel de Economía 2013, quienes obtuvieron este reconocimiento por sus aportaciones empíricas respecto de la predicción del comportamiento de los precios de los activos financieros, desde fundamentos teóricos muy diferentes.

Se analiza la Teoría de los Mercados Eficientes de Eugene Fama, las conductas irracionales de los inversores y la generación de burbujas especulativas desde la perspectiva de Robert Shiller y los aportes de Lars Peter Hansen con el Modelo Generalizado de Momentos.

Se concluye que los mercados se vuelven más eficientes cuando los analistas más creen que son ineficientes y compiten en la búsqueda de información para tratar de beneficiarse de esa ineficiencia. Los analistas normalmente actúan sobre la base de mercados imperfectos, utilizando análisis técnico, realizando análisis fundamental y aceptando que existe información privilegiada; esta realidad hace que los mercados sean mucho más eficientes de lo que creen algunos inversores.

La eficiencia de los mercados es una verdad a medias, los precios de los activos financieros parecen reflejar con frecuencia su valor intrínseco hasta cierto punto y, en situaciones particulares, conductas irracionales generalizadas generan las burbujas.
Aportes teóricos a la gestión organizacional: La evolución en la visión de la organización.. Theoretical contributions to organizational management: Developments in the visión of the organization
Authors: Sánchez Bañuelos María Nélida
Published: July 2017

Con el transcurso del tiempo, el estudio de las organizaciones a través de las teorías ha buscado dar razón del funcionamiento y manejo óptimo para la obtención de mayores ventajas. La constante evolución tecnológica y de información que se ha observado en la actualidad ha permitido la generación y desarrollo de mayores conocimientos, brindando nuevos paradigmas. Partiendo desde la teoría de sistemas, es posible encontrar cambios sustanciales en el estudio de las organizaciones, generando nuevas corrientes o perspectivas teóricas que permiten agrupar el análisis de la organización desde distintos puntos de vista o teorías. Por tanto, dicho análisis teórico parte del cambio de paradigma propuesto por la perspectiva pos-moderna, de igual forma esta se sustenta en la postura teórica de los Estudios organizacionales, así como el uso de la metáfora del organismo. Para ello, mediante el análisis teórico, se trata de hacer una división de corrientes, donde se ve la estrategia y el cambio organizacional de acuerdo a la aparición de cada una de ellas en el tiempo y contexto en que se presentaron. Esta división permitirá contextualizar los cambios que han surgido referentes a la percepción de la organización, así como la visualización del hombre dentro de ella. Permitiendo así, esquematizar el conocimiento brindado por las teorías propuestas, con la intención de encontrar factores importantes que sustenten una evolución en la teoría.
