The effects of explicit instruction of formulaic language on EFL argumentative writing quality
Authors: Akkoç Armağan Bakili , Qin Jingjing , Karabacak Erkan
Published: October 2018

This study investigated the effects of explicit teaching of formulaic language on the overall quality of Turkish EFL university students’ argumentative writing. Forty-four freshmen and twenty-seven sophomores participated in the study, with half of them assigned to the experimental group and the other to the control group. Forty target formulaic language items were explicitly taught to the experimental group with a variety of activities for four hours in two weeks. The experimental group was found to increase the overall quality scores of their writing significantly after the intervention. They also outperformed the control group in the immediate post-test although a decrease was observed in the delayed post-test. Moreover, a significantly positive correlation was observed between the frequency of the formulaic language items used and the overall quality scores of the essays. It seemed that the explicit instruction of the target items raised the students’ awareness of formulaic language and improved the overall quality of their writing.
Teaching philosophy in practice: Developing compatibility through personal practical knowledge
Authors: Kumagai Kazuaki , Black Laurel Johnson
Published: October 2018

As part of an MATESOL mentoring program, developing educators were paired with experienced professors.  The authors explore how personal practical knowledge bridges the gap between teaching philosophy and classroom practice. The complex layers of experience and knowledge that a mentor can offer need to be prompted, however; they cannot simply be deduced by observing. Using observational notes, interviews, and reflection, we explore real-time teaching decisions as a way to elaborate and reconsider the usually succinct teaching philosophy statement. This is particularly important for new teachers and those who are teaching in contexts or with students whose culture is still being absorbed. Personal practice knowledge is seen as the stem from which both teaching philosophy and classroom practice bloom.
The fever of English 2.0 in Indonesia: University students’ and faculty members’ attitudes towards English in different multilingual landscapes
Authors: Abdurahman Nur Hafiz , Gandana Isti Siti Saleha , Novianti Nita
Published: October 2018

The global spread of English has become a widely felt phenomenon, arousing different perceptions and attitudes among those who encounter it. The dominant use of English in virtual spaces has led to the emergence of ‘English 2.0,’ which has been perceived as a new concept of learning English involving networked learning and the use of digital technologies. This study explores Indonesian university students’ and faculty members’ attitudes towards the use of English in both face-to-face and virtual contexts. Adopting a mixed methods approach, it involved two hundred and fifty-one respondents through which questionnaires were distributed and completed. Responses to Likert-scale items were analysed using a paired-samples t-test of SPSS, while open-ended responses were used to yield a more in-depth analysis. The results show that there were mixed attitudes towards English among the respondents. This study suggests that while virtual domains can provide a space for learning and practicing English, a beneficial utilisation of the language ultimately depends on how English language learning is planned and designed.
The Natural, the Artificial and Human Sciences
Authors: Lektorsky V.A.
Published: October 2018

The author analyses the possibilities of transforming human mind in connection with the appearance of “digital civilization” and the development of human sciences, in particular, cognitive and neural ones. The article argues that human sciences can promote human perfection (and will not be used as a means of its degradation) only if they take into account the principal fact: the human being is a natural/artificial creature engaged in activity and culture. In this context the author studies the relationship between individual and collective activity and analyzes different forms of the latter: relative independence of participants, distributed activity, and cooperative activity. Cooperation requires constant communication between the participants. Therefore activity and communication cannot be opposed to each other, as the act of communication matters only in the context of activity, and also because communication itself can be understood as a specific kind of activity. In this connection social constructionism in psychology and other human sciences is criticized.
Category of Development as the Basis of Psychologicaland Pedagogical Research in Education
Authors: Nechaev N.N.
Published: October 2018

The article dwells on the fundamental problem of a person’s psychological development within the joint activity context. The starting point for the author are L.S. Vygotsky’s and D.B. Elkonin’s positions on the source and conditions of development, its psychological mechanism determining the internal dynamic of development. The article presents a systemic view of development as an objective process thus providing the opportunity to specify D.B. Elkonin’s position represented in his conception of child’s development stages periodization. The “dual” character of a subject’s mode of activity is outlined. It means that in the course of joint activity it always finds its realization within the subject’s system of relations by way of the subject’s modes of actions thus providing the possibility to avoid the disruption between motivational (personal) and operational technical (object-oriented) domains of activity still characteristic for the present-day psychology views. The psychological mechanism of a subject activity development is considered as resolution of contradictions that emerge in the course of his involvement into the new forms of joint activity, which demands the respective changes of the modes of actions previously formed which in its turn causes the transformation of the subject’s relations system. It is claimed that in the course of joint activity the concrete modes of the subject’s actions at every stage of his development cease to correspond to the system of his relations being formed thus leading to the transformation of the activity motivational base that determine these modes development.
The Psychology of Art in Vygotsky’s School of Thought: Issues in Theory and Communicative Practices of Working with Consciousness
Authors: Gromyko Y.V.
Published: October 2018

The article analyzes modern theatre practices through the concepts developed by Vygotsky’s school of thought. One of the fundamental features of these practices is working with consciousness, which enables an individual to master his/her own behaviour. The central point of these artful theatre practices is the experience of catharsis that becomes real as two affects meet. Theatre practices are compared with educational practices and collective problem-solving practices, in which the same phenomenon of meeting of affects takes place. The article argues that the orientation system of action is neither symmetrical nor parallel to the affective-motivational system of action. Reorganisation and transformation of emotional experience into affect and action implies the following: the ability to represent emotional experiences as idealized objective states of mind and to be susceptible to their language; the ability to observe emotional experiences from the outside using reflection; the ability to re-establish oneself as the actor by recollecting one’s self in the act of doing.
“In search of our better selves”: Totem Transfer Narratives and Indigenous Futurities
Authors: Hunt Dallas
Published: October 2018

Much contemporary science fiction urges us to focus on eco-activism and sustainable futures in order to prevent environmental catastrophe. From a critical Indigenous and anticolonial perspective, however, the question becomes “for whom are these futures sustainable”? Set in a nondescript desert dystopia, George Miller's film Mad Max: Fury Road 2015 alludes to the westerns of yesteryear and the Australian “outback”—spaces coded as menacing in their resistance to being tamed by settler-colonial interests. This article charts how Miller's film, while preoccupied with issues pertaining to global warming and ecological collapse, replicates and reifies settler replacement narratives, or what Canadian literature scholar Margery Fee has referred to as “totem transfer” narratives (1987). In these narratives, ultimately the “natives” transfer their knowledges and then disappear from view, helping white settlers remedy the self-created ills that currently threaten their worlds and enabling them to inherit the land.

In the second half, I also consider how Indigenous futurist texts offer decolonizing potentials that refute the replacement narratives that persist in settler-colonial contexts. In particular, I examine how Indigenous cultural production emphasizes the importance of the intergenerational transfer of Indigenous knowledges and refuses the hermeneutic of reconciliation that seeks to discipline Indigenous futures in the service of a settler-colonial present.
Age-related aspects of differential diagnosis of acute cough in children and adults
Authors: Leshchenko I. V. , Tsar’kova S. A. , Zherebtsov A. D.
Published: October 2018

Cough is one of the most common causes of seeking the primary medical care, especially during the autumn and the spring. This article is a review of literature  aimed at differential diagnosis of possible causes of acute cough in children and  adults. Given a vast majority of diseases associated with cough, differential diagnosis  have to consider several issues. The key issue is cough duration and possible  anatomical location of the pathological changes. An algorithm of differential diagnosis  of acute cough in children and adults and description of most common diseases  associated with acute cough are given in the review. Further diagnostic work-up  should be driven by the duration of cough as soon as the acute cough could be first  manifestation of a chronic disease.
Acute exacerbation of idiopathic pulmonary fibrosis
Authors: Avdeev S. N.
Published: October 2018

Acute exacerbation of idiopathic pulmonary fibrosis (AE-IPF) is defined as an acute clinically significant respiratory deterioration characterized by evidence of new,  widespread alveolar abnormalities, such as diffuse bilateral ground-glass  opacification and/or consolidation, and the absence of other obvious clinical causes  like fluid overload, left heart failure, or pulmonary embolism, etc. AE-IPF is  subcategorized as “triggered” (where specific causes are identified, for example,  infections, surgery procedures, drug toxicity, etc.) or “idiopathic” (where no specific causes are identified). In randomized trials, the annual incidence of AE-IPF is about 8%, in retrospective studies it reaches 19%. Severe forms of IPF are an important  risk factor for the development of AE-IPF. In-hospital mortality from AE-IPF is more  than 50%, and the average survival of patients with AE-IPF is 1–4 months.  Currently, there remain no proven, effective therapies for AE-IPF. In real clinical  practice patients with AE-IPF still receive high doses of systemic corticosteroids and antibiotics. Antifibrotic therapy can reduce the risk of exacerbations; it has been  shown that therapy with nintedanib leads to a reduction in the number of  confirmed/suspected AE-IPF by 68%. It is necessary to further study the potential  methods of prevention and therapy of AE-IPF in future clinical trials.

Published: October 2018

Este trabalho analisa as contribuições do curso pré-vestibular Universidade Para Todos (UPT) para o acesso de jovens ao Ensino Superior. Explana-se sobre a ausência de perspectivas dos estudantes egressos do Ensino Médio no que tange este nível educacional e o baixo grau de instrução dos pais para orientarem os filhos. Salienta-se a importância do curso de nível superior para o enriquecimento intelectual e possibilitar melhores postos no mercado de trabalho. Segue-se a perspectiva metodológica de revisão bibliográfica sobre o tema evidenciado e a análise de entrevistas realizadas com 25 (vinte e cinco) ex-alunos do curso UPT, em Aracatu, Bahia. Os resultados evidenciam que a maioria dos entrevistados opta por cursos de nível superior relacionados a licenciaturas, justificam as escolhas na distância geográfica da universidade, já que é mais viável realizar um curso mais próximo da residência, devido à condição socioeconômica. O curso foi avaliado como excelente ou bom, visto que auxiliou nos vestibulares realizados. Deve-se ter pontualidade na entrega dos materiais didáticos.  É perceptível que o curso UPT, mesmo com problemas estruturais, contribuiu para que estes estudantes conseguissem acesso ao ensino superior e ao mercado de trabalho.

O presente trabalho tem como objetivo precípuo descrever as experiências e vivências de mulheres vítimas de violência doméstica atendidas pelo Projeto Mulheres Mil no Instituto Federal de Educação, Ciência e Tecnologia do Maranhão (Ifma) – Campus Codó. O Programa Mulheres Mil constitui-se uma ferramenta educacional para o benefício de mulheres em situação de vulnerabilidade social e muitas dessas mulheres são vítimas de violência perpetrada por seus companheiros e/ou ex-companheiros. Estruturado em três eixos – Educação, Cidadania e Desenvolvimento Sustentável – o programa possibilita a inclusão social, por meio da oferta de formação focada na autonomia e na criação de alternativas para a inserção no mundo do trabalho, para que essas mulheres consigam melhorar a qualidade de suas vidas e de suas comunidades. Nessa perspectiva o Ifma –Campus Codó está desenvolvendo esta experiência viabilizando o ingresso e a permanência com êxito da população feminina das comunidades que ficam localizadas no entorno do Instituto Federal. O Projeto surge como uma possibilidade de aliar a educação ao trabalho, visando à diminuição de problemas sociais em comunidades de baixo índice de desenvolvimento humano e principalmente para amenizar o índice de violência contra a mulher e fomentar essa discussão no espaço educacional. O Ifma - Campus Codó, aderiu ao Programa na Chamada Pública MEC/Setec - 06/2012, para atender mulheres em Cursos Básico de Qualificação Profissional. A relevância desta experiência está contida na problemática das minorias que estão à margem de políticas públicas compensatórias e reparadoras para a igualdade de gênero.

Authors: Sá Jr. Edilson Mineiro , Daher Sergio , Antunes Fernando L. M. , Cruz Cícero M. T. , Silva Kátia M. , Figueira A. Ribamar
Published: October 2018

This paper describes the design and implementation of a grid connected photovoltaic system aimed to supply energy to the public lighting during the time of high peak demand of the grid. The system is made of two main parts: the solar energy storage unit and the lighting unit. The energy storage unit is composed by a PV panel operating at its maximum power point (MPP) and a battery charger. The lighting unit is composed by an electronic reactor (ballast) for high pressure sodium (HPS) lamp, that operates with zero-voltage switching (ZVS), and a flyback converter to boost the battery voltage to the level required by the electronic reactor. The interconnection between the electric grid and the proposed system is made by a rectifier with a power factor correction (PFC) stage connected in dc link of the electronic reactor. A microcontroller determines if the battery bank or the grid supplies the lighting unit. Simulation and experimental results for the proposed system supplying a 70W HPS lamp are presented. A prototype, which is in continuous operation for more than two years in the field, is also presented.

High Performance Inverter For Renewable Energy Systems
Authors: Daher Sérgio , Schmid Jürgen , Antunes Fernando
Published: October 2018

This paper makes an analysis of the current demand on inverters for stand-alone renewable energy applications, and shows that reliability, surge power capability and efficiency are the most important aspects to be considered. It is shown that multilevel topologies can be very suitable for these applications due to their inherent high efficiency and robustness. In addition, it is shown that an optimized design must be in agreement with the typical load profile for stand-alone applications. A prototype of 3 kVA was implemented and it has proved itself to be robust. Peak efficiency of 96.0% was achieved: value that is higher than similar high performance inverters currently available in the market.
Inversor Push-pull Modificado De Três Níveis
Authors: Galotto Jr Luigi , Tatibana Gilberto S. , Pinto João Onofre P. , Godoy Ruben B. , Teixeira Filho Faete J. , Maia Helder Z.
Published: October 2018

O objetivo deste trabalho é apresentar uma topologia de um inversor push-pull de três níveis, denominado push-pull modificado. Algumas topologias com o mesmo objetivo já foram propostas [2-3], mas, em geral, não apresentam vantagens em relação a um inversor de ponte completa. A simplicidade é a principal vantagem dos conversores push-pull, o que os torna atrativos para aplicações de baixa potência. O inversor proposto é obtido adicionando-se apenas uma chave ao push-pull padrão. Esta nova topologia permite controle completo de três níveis, utilizando menor quantidade de chaves comparado a um inversor de ponte completa. Primeiramente, a topologia do inversor será apresentada e, então, os passos de operação serão descritos, mostrando os princípios de operação e as leis de controle. Uma comparação entre quatro topologias de inversores também é apresentada. Finalmente, simulações e resultados experimentais são mostrados para a validação da topologia. Esse novo inversor é viável para aplicações com baixas tensões de entrada e que demandam modulação de três níveis, como em sistemas de geração distribuída baseada em energia renovável.

Published: October 2018

Na distante Ásia foram relatadas várias avarias sem causa aparente em máquinas síncronas de ímã permanente (MSIP) empregadas em aerogeradores de pequeno porte instalados em comunidades isoladas. A causa principal deste problema foi atribuída às perdas adicionais causadas no cobre devido aos componentes harmônicos das correntes estatóricas aos quais a MSIP estava submetida pela ação do retificador trifásico convencional com filtro capacitivo conectado aos seus terminais. Este trabalho apresenta uma proposta que visa a minimizar este problema empregando um préregulador de fator de potência (PFP) do tipo elevador operando no modo de condução descontínua (MCD). Os resultados confirmam a efetividade do método que emprega um PFP para a mitigação do conteúdo harmônico e redução das perdas internas da MSIP.

Published: October 2018

A presente pesquisa tem por objetivo caracterizar tipologias essenciais do fenômeno da prática pianística baseadas nos procedimentos adotados por quatro pianistas em diferentes níveis acadêmicos (extensão, graduação, pós-graduação e profissional), tendo em vista as perspectivas de deliberação. A metodologia, de cunho fenomenológico, compreendeu a gravação em áudio e vídeo de uma sessão de prática de duas peças do repertório de cada participante e uma entrevista semiestruturada. Os dados foram analisados sob uma perspectiva qualitativa e quantitativa, resultando em nove Categorias Psicossensoriais (assim denominadas por englobarem aspectos de natureza psicológica e sensorial da prática), das quais seis delas são aqui discutidas em termos de procedimentos e eficácia. Os resultados indicam que as perspectivas de deliberação ocorrem pela forma com que essas categorias são estruturadas e frequentemente empregadas em função da expertise: níveis mais elementares demonstraram procedimentos recorrentes, menos variados e com alguma estruturação em desenvolvimento, ao passo que tal estruturação e variedade mostraram-se sistematizadas e distribuídas regularmente à medida que a expertise aumentava.

Published: October 2018

ResumenEl objetivo del presente trabajo es comparar el comportamiento de los elementos estructurales sometidos a flexión o compresión después de haber sido reparados, mediante la sustitución del hormigón deteriorado por mortero de cemento Portland o mortero modificado con polímeros. En primer lugar, las probetas cúbicas se fabricaron con diferentes proporciones de reparación de mortero de cemento para ensayar a compresión, con los materiales colocados tanto en serie como en paralelo. Del análisis de resultados, se puede concluir que los sistemas mixtos - mortero de hormigón modificado con polímeros sometido a compresión pueden soportar cargas mayores que la reparación del mortero de cemento Portland, aunque en ningún caso pueden restaurar la capacidad de carga del hormigón. En los elementos sometidos a flexión, las vigas reparadas pueden alcanzar la resistencia inicial a la fractura de las vigas y soportar cargas aún mayores. Por lo tanto, la reparación de estructuras de cemento deterioradas con morteros de reparación es una buena alternativa, especialmente en elementos estructurales sometidos a flexión, y se realizan con morteros de cemento Portland. En las estructuras sometidas a compresión, es mejor utilizar morteros de reparación modificados con polímeros que aumentan la ductilidad cuando el mortero de reparación se ubica en serie con respecto a la carga.AbstractThe aim of the present work is to compare the behavior of structural elements subjected to bending or compression after having been repaired, by substituting the deteriorated concrete by Portland cement mortar or mortar modified with polymers. Firstly, cubic specimens were manufactured with different repair concrete-mortar proportions to be tested to compression, with the materials placed both in series and in parallel. From the results analysis, it can be concluded that mixed systems - polymer-modified concrete mortar subjected to compression can withstand greater loads than the repair Portland cement mortar, although they are in no case able to restore the load capacity of concrete. In elements subjected to bending, the repaired beams are able to achieve the initial fracture strength of the beams, and support even higher loads. Therefore, repairing deteriorated concrete structures using repair mortars is a good alternative, especially in structural elements subjected to bending, and performed using Portland cement mortars. In structures subject to compression, it is better to use repair mortars modified with polymers which increase the ductility when the repair mortar is located in series regarding the load

ResumenEl mayor consumo energético en el sector residencial se debe a las instalaciones de climatización. Existen numerosos estudios de viviendas plurifamiliares orientados a optimizar este ítem, pero pocos se centran en la vivienda unifamiliar. Un punto crítico en esta tipología edificatoria son los huecos de ventanas, que suponen una gran superficie sobre el total de la envolvente. El objetivo de este trabajo es analizar, cuantificar y valorar la influencia de estrategias pasivas, consistentes en la instalación de diferentes tipos de acristalamientos y protecciones solares, teniendo en cuenta la orientación de la vivienda, para reducir la demanda energética de climatización. El análisis de resultados ofrece unas pautas que demuestran el comportamiento de las diferentes estrategias pasivas utilizadas y su repercusión directa en la demanda de diseño de los equipos de climatización. No siendo soluciones únicas, pero si orientativas a la hora de proponer decisiones adaptables a tipologías edificatorias similares.AbstractThe highest energy consumption in the residential sector is due to the air conditioning installations. There are numerous stud-ies of flats oriented to optimize this item, but few focus on the detached house. A critical point in this building typology are the window aperture, which suppose a great surface on the total of the envelope. Therefore, the objective of this work is to analyze, quantify and assess the influence of different passive strategies, which consists of the installation of different types of glazing and solar protections, taking into account the orientation of the house, to reduce the energy demand of air conditioning. The analysis of results provides guidelines for the behavior of different strategies and their direct impact on the design demand of refrigeration and heating equipment. They are not unique solutions, but they are indicative when proposing decisions adapt-able to similar building typologies.

Las propiedades de fractura y el comportamiento posterior al agrietamiento del hormigón, se analizaron sobre la base de las curvas de desplazamiento de la abertura de grietas de carga (P-CMOD). Las fibras de basalto cortadas (50 mm de longitud, 0,02 mm de diámetro) se agregaron al hormigón de cemento con un contenido de 2,0; 4,0 y 8,0 kg/m3. La adición de la fracción volumétrica considerada de fibras de basalto tuvo una influencia significativa en las propiedades de fractura del hormigón, mientras que las fibras tuvieron un ligero efecto en las propiedades de resistencia del hormigón. Las fibras de basalto causaron la mejora de los parámetros de fractura como KIc, CTODc y la energía de fractura total GF. El análisis de los diagramas P-CMOD demostró que el comportamiento de la fractura después de la fractura del haz se mejoró mucho mediante la adición de fibras de basalto. Los resultados de la medición de la dureza y las características de absorción de energía mostraron que las muestras de hormigón reforzado con fibrasmejoran su comportamiento dúctil y su capacidad de absorción de energía, en comparación con las muestras de hormigón ordinario.AbstractA three-point bending method was used in the study to determine the fracture toughness of concretes with basalt fibers. The post-cracking behavior and fracture properties of concrete were analyzed on the basis of load–crack mouth opening displacement (P–CMOD) curves. The chopped basalt fibers (50 mm length; 0.02 mm diameter) were added to cement concrete at the contents of 2,0; 4,0 and 8,0 kg/m3. The addition of the considered volume fraction of basalt fibers had significant influence on the fracture properties of concrete, while the fibers had slight effect on the strength properties of concrete. The basalt fibers caused the improvement of the fracture parameters as KIc, CTODc and total fracture energy GF. The analysis of P-CMOD diagrams proved that the post-cracking fracture behavior of the beam was greatly improved by the addition of basalt fibers. The results of measuring the toughness and energy-absorption characteristics showed that fiber reinforced concrete specimens acquire a great ductile behavior and energy absorption capacity, compared to ordinary concrete specimens.

Defects are considered one of the wastes in manufacturing systems that negatively affect the delivery times, cost and quality of products leading to manufacturing companies facing a critical situation with the customers and to not comply with the IPC-A-610E standard for the acceptability of electronic components. This is the case is a manufacturing company located in Tijuana, Mexico. Due to an increasing demand on the products manufactured by this company, several defects have been detected in the welding process of electronic boards, as well as in the components named Thru-Holes. It is for this reason that this paper presents a lean manufacturing application case study. The objective of this research is to reduce at least 20% the defects generated during the welding process. In addition, it is intended to increase 20% the capacity of 3 double production lines where electronic boards are processed. As method, the PDCA cycle, is applied. The Pareto charts and the flowchart are used as support tools. As results, defects decreased 65%, 79% and 77% in three analyzed product models. As conclusion, the PDCA cycle, the Pareto charts, and the flowchart are excellent quality tools that help decrease the number of defective components.

This manuscript introduces prospective hard engineering solutions to continuous episodic erosional events on beaches utilized for recreation and tourism. The basis of this paper is information from a modeling study completed in 2011 on a two mile stretch of beach in South Carolina. The study utilized three alternative groin systems and a no groin option. The optimum spacing of the groin applications and the retention rate of a replenished beach at the location was determined based on running a computer model (Genesis) for the environmental conditions (wave climate, littoral transport, etc.) at the demonstration site. It was also determined that the innovative groin alternative presented in this paper would likely develop as the most effective cost/benefit relationship among the more conventional alternatives utilized in the United States. The experimental groin system (modular adjustable permeable groin(s) MAPG) was calculated to save initial construction costs by 25% to 30%as compared to the other alternatives. This was significant when considering that adjacent beach impacts are minimized and the beach berm is better protected over the typical beach re-nourishment cycle. This paper attempts to facilitate further discussion of regional sediment budget and (coastal zone) management by bridging the divide between choosing only sand nourishment vs. engineered structures. We demonstrate that reintroducing engineered structures in combination with beach nourishment can be a cost effective solution to episodic erosional events over time while allowing longshore sediment transport.
Improve Building Façades in Open Lidar Data Using Ground Imagery

Recent advances in open data initiatives allow us to free access to a vast amount of open LiDAR data in many cities. However, most of these open LiDAR data over cities are acquired by airborne scanning, where the points on façades are sparse or even completely missing due to the viewpoint and object occlusions in the urban environment. Integrating other sources of data, such as ground images, to complete the missing parts is an effective and practical solution. This paper presents an approach for improving open LiDAR data coverage on building façades by using point cloud generated from ground images. A coarse-to-fine strategy is proposed to fuse these two different sources of data. Firstly, the façade point cloud generated from terrestrial images is initially geolocated by matching the SFM camera positions to their GPS meta-information. Next, an improved Coherent Point Drift algorithm with normal consistency is proposed to accurately align building façades to open LiDAR data. The significance of the work resides in the use of 2D overlapping points on the outline of buildings instead of limited 3D overlap between the two point clouds and the achievement to a reliable and precise registration under possible incomplete coverage and ambiguous correspondence. Experiments show that the proposed approach can significantly improve the façades details of buildings in open LiDAR data and improving registration accuracy from up to 10 meters to less than half a meter compared to classic registration methods.

Age-related macular degeneration (AMD) is a complex multifactorial disease and the primary cause of legal and irreversible blindness among individuals aged >=65 years in developed countries. Globally, it affects 30-50 million individuals, with an estimated increase of approximately 200 million by 2020 and approximately 300 million by 2040. Currently, the neovascular form may be able to be treated with the use of anti-VEGF drugs, while no effective treatments are available for the dry form. Many observational studies, such as AREDS-1 and AREDS 2, have shown a potential role of micronutrient supplementation in lowering the risk of progression of the early stages of AMD. Recently, low-grade inflammation, sustained by dysbiosis and a leaky gut, has been shown to contribute to the development of AMD. Given the ascertained influence of the gut microbiota in systemic low-grade inflammation and its potential modulation by macro- and micro-nutrients, a potential role of diet in AMD has been proposed. This review discusses the role of the gut microbiota in the development of AMD. Using PubMed, Web of Science and Scopus, we searched for recent scientific evidence discussing the impact of dietary habits (high fat and high glucose or fructose diets), micronutrients (vitamins C, E, and D, zinc, beta-carotene, lutein and zeaxanthin) and omega-3 fatty acids on the modulation of the gut microbiota and their relationship with AMD risk and progression.

It has been widely described that chronic intake of fructose causes metabolic alterations which can be associated with brain function impairment. In this study, we evaluated the effects of fructose intake on the sleep-wake cycle, locomotion and neurochemical parameters in Wistar rats. The experimental group was fed with 10% fructose in drinking water for five weeks. After treatment, metabolic indicators were quantified in blood. Electroencephalographic recordings were used to evaluate the sleep architecture and the spectral power of frequency bands. Likewise, the locomotor activity and the concentrations of orexin A and monoamines were estimated. Our results show that fructose diet significantly increased the blood levels of glucose, cholesterol, and triglycerides. Fructose modified the sleep-wake cycle of rats increasing the waking duration and conversely decreasing the non-rapid eye movement sleep. Furthermore, these effects were accompanied by increases of the spectral power at different frequency bands. Chronic consumption of fructose caused a slight increase in the locomotor activity as well as an increase of orexin-A and dopamine levels in the hypothalamus and brainstem. Specifically, immunoreactivity for orexin-A was increased in the ventral tegmental area after the intake of fructose. Our study suggests that fructose induces metabolic changes and stimulates the activity of orexinergic and dopaminergic neurons which may be responsible for alterations of the sleep-wake cycle.
