RESUMO - O presente trabalho teve como objetivo verificar os impactos das mudanças climáticas no desenvolvimento e evapotranspiração do milho, no semiárido brasileiro. O trabalho foi desenvolvido nos municípios de Apodi, Ipanguaçu e Mossoró, todos eles localizados no estado do Rio Grande do Norte. A determinação da evapotranspiração da cultura (ETc), em suas diferentes fases, foi realizada através de lisímetros de pesagem. Para verificar a influência das mudanças climáticas no consumo hídrico da cultura foram simuladas alterações na temperatura e na umidade relativa do ar, através do modelo climático PRECIS. Foram avaliados dois cenários de emissões baseados no relatório do IPCC (Intergovernmental Panel on Climate Change), um pessimista (A2) e um otimista (B2). Os dados de temperatura e umidade relativa utilizados foram as saídas do modelo PRECIS. Segundo as projeções do modelo as temperaturas na região ficarão muito acima do limite ótimo para o desenvolvimento da cultura. A duração do ciclo da cultura apresentou uma redução média de 10 e 15 dias para os cenários B2 e A2, respectivamente. A redução no ciclo também provocou uma diminuição de 3,0% na evapotranspiração total, considerando o cenário mais otimista, e de 4,4% no cenário mais pessimista.Palavras-chave: Zea mays, temperatura, umidade relativa, evapotranspiração. DEVELOPMENT AND WATER REQUIREMENT OF MAIZE CROP AFFECTED BY CLIMATE CHANGES IN THE SEMIARID REGION OF THE BRAZILIAN NORTHEAST  ABSTRACT - This study aimed to determine the impacts of climate changes on growth and evapotranspiration of maize in the Brazilian semiarid region. The study was conducted in the municipalities of Apodí, Ipanguaçu and Mossoró, all of them located in the state of Rio Grande do Norte. The determination of evapotranspiration (ETc) throughout the different crop phases was accomplished by weighing lysimeters.In order to check the effect of climate changes on crop water consumption, simulated changes were done in the temperature and relative humidity of the air, through the PRECIS climate model. Two scenarios of emissions were evaluated based on the IPCC report (Intergovernmental Panel on Climate Change): a pessimistic caled A2 and an optimistic B2. The data of temperature and relative humidity were obtained by the PRECIS model. According to the model projections, the temperatures in the region will be far above the optimal limit for crop development. The crop cycle showed an average reduction of 10 and 15 days for B2 and A2 scenarios, respectively. The reduction in the cycle also caused a decrease in the total evapotranspiration of 3.0%, considering the most optimistic scenario, and 4.4% in the worst scenario.keywords: Zea mays, temperature, relative humidity, evapotranspiration.

Resumo: A utilização de tratores e implementos agrícolas é amplamente difundida em todos os tipos de cultura, atendendo às necessidades das diferentes escalas de produção das propriedades rurais. Um dos principais desafios inerentes ao uso desse tipo de equipamento é a dificuldade de aperfeiçoar seu emprego, estabelecendo-se condições de operação, que propiciem o equilíbrio entre a alta capacidade de trabalho que a mecanização agrícola proporciona, o consumo adequado de energia e a sustentabilidade da área de produção. Este trabalho descreve as etapas de implementação de um sistema de aquisição de dados e visa avaliar o desempenho energético de um conjunto trator-implemento, utilizando um computador de placa única baseado na arquitetura ARM e sensores diversos. Algoritmos foram escritos em linguagem de programação C++ a fim de obter os sinais provenientes de cada um dos sensores e trata-los conforme sua natureza e grandeza física a ser mensurada. Após a etapa de programação, os sensores foram individualmente testados e calibrados em bancada e, posteriormente, o sistema como um todo foi testado no conjunto trator-implemento. O sistema mostrou-se uma ferramenta válida para auxiliar na tomada de decisão em operações de campo envolvendo máquinas agrícolas.Palavras-chave: mecanização agrícola, instrumentação eletrônica, sistemas embarcados. HIGH CAPACITY EMBEDDED COMPUTER WITH C++ FOR EVALUATING TRACTOR PERFORMANCE AT FIELD  Abstract: Agricultural machinery and implements have been widely used in all crops, supporting the needs of several productive scales. One of the main challenges to the use of such equipment is the difficulty of optimizing its usage, establishing operational conditions that allow the balance between the high performance provided by agricultural mechanization and the sustainability of the planting area. This paper describes the steps in implementing a high capacity acquisition system that allows evaluating the energetic performance of a set of tractor-implement using a single-board computer based on ARM architecture and sensors. The C++ programming language was chosen to implement the algorithms that read the signals provided by sensors and treat them according to the measured physical quantity. Thereafter, the sensors were individually tested in the laboratory and also at field with all sensors connected to the embedded computer. The system proved to be a valid tool to aid in decision making in operations with agricultural machinery.Keywords: agricultural mechanization, electronic instrumentation, embedded systems.

Published: September 2018

In this study, nanocomposites were formed together with
Keggin-type K7-xNaxPW11O39∙14H2O
(POTs) clusters
and oxygenated-graphene (Oxy-G). It was produced as a multilayer by
layer-by-layer self-assembly method using protonated poly (ethylenimine) (PEI).
The produced (PEI / POTs / Oxy-G) n multilayer films were controlled by XRD,
cyclic voltammetry and UV-visible spectroscopy. (PEI / POTs / Oxy-G) n

reaction taking advantage of the electrocatalytic activity of this
nanocomposite. Multilayer has been shown to exhibit a potentially good
electrocatalytic activity at -0.4 V. A notable electrocatalytic hydrogen
evolution reaction could be identified on the (PEI/ POTs/Oxy-G)n multilayer.

A Negative-sequence Current Injection Method to Mitigate Voltage Imbalances in Microgrids
Authors: Azevedo Gustavo M. S. , Rocabert Joan , Cavalcanti Marcelo C. , Neves Francisco A. S. , Rodriguez Pedro
Published: September 2018

This paper proposes a control strategy to reduce the voltage imbalances by injection of a proper negative-sequence current into the microgrid. This task can be done by each inverter connected to the microgrid in a shared way. The current compensation reference is obtained through a negative-sequence voltage control loop, avoiding the load current measurement. The detection of the negative-sequence voltage, at the converter connection point, is performed by a double second order generalized integrator, properly tuned for this purpose. Besides, a current limiter is used to limit the current compensation and avoid the converter overload. This strategy neither requires any hardware modification of the converter nor additional sensors. This new control strategy is simulated in Matlab/Simulink and experimental results are presented to prove its effectiveness.

Published: September 2018

Com o objetivo de avaliar a aplicação da Teoria de Potência Conservativa (CPT, do inglês Conservative Power Theory), para o controle de filtros ativos de potência, este artigo apresenta uma metodologia seletiva para a geração de sinais de referência de filtros ativos paralelos, a qual é baseada na decomposição das correntes medidas, conforme proposto pela CPT. A decomposição ortogonal das correntes resulta em várias componentes, cada qual associada com uma característica específica da carga (transferência de potência, armazenamento de energia, deslocamento de fase entre tensão e corrente, desbalanço e/ou não linearidades). Desta forma, cada componente pode ser escolhida de forma independente (ou em associação), proporcionando assim uma compensação seletiva dos distúrbios de corrente oriundos do comportamento da carga. Com o intuito de validar a metodologia proposta, um filtro ativo trifásico foi simulado e avaliado experimentalmente em um sistema trifásico de 4 condutores, com cargas desbalanceadas e não lineares.

Абстрактные. В статье описаны полученные экспериментальные результаты для планарного акустоплазменного магнетрона. Небольшой радиус анодной петли позволяет фокусировать и ускорять ионный компонент распыленного материала. В качестве буферного газа использовали аргон. Сравниваются характеристики магнетрона в случае постоянного тока и в акустоплазменном режиме (AP) (с модулированным током, содержащим постоянные и переменные компоненты). Скорость распыления в режиме AP увеличивается. Для медного катода давление газа составляло <1 Па и плотность тока порядка 100 мА / см 2с увеличением расстояния от анода до осажденного субстрата от 2 до 4 см в случае подачи постоянного тока скорость осаждения снижается в 3,3 раза (от 17 до 5 нм / с), в акустоплазменном режиме - в 2 раза (от 13 до 6,4 нм / с). Для расстояния анода-подложки 4 см прирост скорости осаждения в режиме AP по сравнению с DC составляет 1,2-1,5 раза. Измерялись зависимости ионного и электронного токов на подложке от разных параметров разряда. Исследование основано на схеме с двумя потенциальными сетками с фиксированными и переменными потенциалами. Показана возможность формирования кольцевого пароплазменного потока быстрых частиц.

Published: October 2018

The paper studies the penetration of nitrogen, oxygen, hydrogen, carbon, argon and krypton into copper, nickel, molybdenum, titanium, aluminum, iron and different steels under the action of spark discharges in various media based on radioactive indicators using step-by-step radiometric analysis, macro-, micro-, electron-microscopy and activation autoradiography, Mössbauer and Auger spectroscopy, secondary ion-ionic emission, X-ray diffraction and X-ray microanalysis. The study describes distribution features of penetrating atoms and their concentration profiles. Phase composition of near-surface layers is also determined. It is shown that supersaturated solid solutions of iron in copper and copper in iron are formed during simultaneous iron and oxygen penetration in copper and spinel (Fe6Cu3O4)4. Diffusion of iron and carbon results in supersaturated solid solutions of iron and carbon in copper, copper and carbon in iron, graphite and cementite. Inert gases and nitrogen form solid solutions with copper. Phase composition of near-surface layers in Fe is determined. Iron dioxide FeO, a carbon solid solution in iron with fcc lattice γ-Fe, tetragonal martensite and cementite, two iron (III) hydroxide FeOOH modifications, a supersaturated solid solution of nitrogen and nitride Fe4N, solid solutions of inert gases in iron are formed in the diffusion zone. Simultaneous interaction of molybdenum with iron (the anode material) and various gases results in the formation of substitutional solid solutions of iron in molybdenum and molybdenum in iron, a small amount of interstitial solid solutions of nitrogen and carbon in molybdenum and nitrogen in iron, interstitial phases: molybdenum nitrides and carbides and traces of nitrides of iron (Fe4N, Fe2N) and Fe1,9Mo (λ) phases in the form of needles. Treatment of nickel with a nickel anode in the nitrogen medium promotes formation of a solid solution of nitrogen and nitride Ni3N in the matrix with preserved hexagonal symmetry and lattice parameters that are characteristic of this phase under equilibrium conditions. Atoms of oxygen, nitrogen, carbon and argon are present in the interstitial solid solutions in treatment of nickel in ambient air; however, oxides are not found even on the surface (in the layer ~200 nm). Interaction of titanium with atmospheric gases leads to formation of a solid solution of nitrogen, oxygen, carbon, hydrogen and argon in titanium and titanium nitride Ti2N (ε). Simultaneous saturation of the titanium surface with nickel and nitrogen in the interaction zone causes formation of phases in the following order: nickel nitride; a solid solution of nitrogen and titanium in nickel and a solid solution of both alloying elements in titanium.

Defensa de la objeción de conciencia como derecho general = In defense of a general right to conscientious objection
Authors: Gascón Abellán Marina
Published: October 2018

Resumen: Defiendo en este trabajo que la libertad de conciencia otorga protección a la objeción de conciencia con carácter general, por lo que en principio se puede invocar objeción frente a un deber jurídico sin que sea imprescindible que esta goce de expreso reconocimiento legal. Dicha protección es obviamente prima facie o condicionada, y la protección definitiva dependerá de que se cumplan ciertos requisitos. En la segunda parte examino esos requisitos (relativos fundamentalmente a la seriedad y veracidad de las convicciones y creencias, y a que en todo caso queden tutelados los bienes públicos y los derechos de los demás protegidos por el deber objetado) y finalmente sostengo la conveniencia de regular los tipos de objeción más relevantes.Palabras clave: Libertad de conciencia, libertad de pensamiento, conciencia y religión, objeción de conciencia, derechos humanos, orden público.Abstract: I advocate here the thesis that there is a general right to conscientious objection based on the freedom of conscience, which means it is possible for a person to invoke conscientious objection to avoid performing a legal obligation even though there is no legal provision expressly recognizing to do so. A general right to conscientious objection cannot be interpreted in absolute terms. Conscientious objection in a particular case can only be accepted if certain requirements are met. I also examine those requirements: particularly the need to hold genuine convictions or religious beliefs and protect public order and the rights of others. Finally, I claim it would be convenient to regulate the most relevant forms of conscientious objection, and some suggestions on the matter will be proposed.Keywords: Freedom of conscience, freedom of thought, conscience and religion, conscientious objection, human rights, public order.

Love as Sacrifice: A Motion Toward Reconciliation
Authors: Thorkildsen Kari Marie , Råholm Maj-Britt
Published: October 2018

The aim was to search for an understanding of sacrifice and reconciliation through a hermeneutical reading of Nygren’s text, “Reconciliation, a work of God.” Sacrifice emerged as a motion toward reconciliation entailing a giving up of one’s ego in order to receive grace and holiness, that is, health and alleviated suffering. This makes it possible to dedicate oneself and thus to pass on the love that one has received by accepting the suffering human being as a gift and helping the sufferer embark on the path to sacrifice and reconciliation, and the quest for the source of health in himself/herself.

Visual Inertial Odometry with Robust Initialization and Online Scale Estimation
Authors: Hong Euntae , Lim Jongwoo
Published: September 2018

Visual inertial odometry (VIO) has recently received much attention for efficient and accurate ego-motion estimation of unmanned aerial vehicle systems (UAVs). Recent studies have shown that optimization-based algorithms achieve typically high accuracy when given enough amount of information, but occasionally suffer from divergence when solving highly non-linear problems. Further, their performance significantly depends on the accuracy of the initialization of inertial measurement unit (IMU) parameters. In this paper, we propose a novel VIO algorithm of estimating the motional state of UAVs with high accuracy. The main technical contributions are the fusion of visual information and pre-integrated inertial measurements in a joint optimization framework, and the stable initialization of scale and gravity using relative pose constraints. To count for ambiguity and uncertainty of VIO initialization, a local scale parameter is adopted in the online optimization. Quantitative comparisons with the state-of-the-art algorithms on the EuRoC dataset verify the efficacy and accuracy of the proposed method.
More on Permanent Dissipative Structures in Water: The Matrix of Life
Authors: Sepehri Alireza
Published: September 2018

Recently, some authors have presented a short review of theoretical and experimental evidences of the formation of dissipative structures as the matrix of life in liquid water and shown their spontaneous quantum origin. We generalize this consideration and show that DNA can produce some hexagonal and pentagonal super-molecules in liquid water. We examine the model in shell less culture system and show that DNAs of stem cells of chick embryo produce some special structures in liquid water. We obtain the entropy for producing these DNA-like structures in water around a chick embryo in terms of temperature, rotating velocity and intensity of waves. Comparing this entropy with experimental data, we observe that our model conrms observations.

Published: September 2018

This paper deals with the design, simulation and implementation of shunt hybrid compensator to maintain the power quality in 3-phase distribution networks feeding different types balanced and unbalanced nonlinear loads. The configuration of the compensator consists of a selective harmonic elimination passive filter, a series connected conventional 6-pulse IGBT inverter, acting as the active filter terminated with a dc link capacitor. The theory and modelling of the compensator based on current harmonic components at the load end and their decomposition in d-q axis frame of reference are utilized in the reference current generation algorithm. Accordingly, the source current waveform is made to follow the reference current waveform using a high frequency carrier based controller. Further, this inner current control loop is supported by a slower outer voltage control loop for sustaining desirable dc link voltage. Performance of the compensator is evaluated through MATLAB simulation covering different types of loads and reduction of harmonic currents and THD at the supply side along with excellent regulation of dc link voltage are confirmed. The performance of a hybrid compensator designed and fabricated using the above principles is evaluated and corroborated with the simulation results.
Unfolded Protein Response-Dependent Communication and Contact among Endoplasmic Reticulum, Mitochondria and Plasma Membrane.
Authors: Saito Atsushi , Imaizumi Kazunori
Published: September 2018

The function of the endoplasmic reticulum (ER) can be impaired by the alternation of the extra- and intracellular environment such as disruption of calcium homeostasis, expression of mutated proteins and oxidative stress. In response to disruptions to ER homeostasis, eukaryotic cells activate canonical branches of signal transduction cascades, collectively termed the unfolded protein response (UPR). The UPR attempts to recover the protein folding capacity and avoid irreversible cellular damage. Additionally, the UPR has been shown to play unique physiological roles in the regulation of diverse cellular events, including cell differentiation and development and lipid biosynthesis. Recent studies have indicated that these important cellular events are also regulated by contact and communication among organelles. These reports suggest strong involvement among the UPR, organelle communication and regulation of cellular homeostasis. However, the precise mechanisms for the formation of contact sites and the regulation of its dynamics by UPR remain unresolved. In this review, we summarized the current understanding of how the UPR regulates morphological changes to the ER and the formation of contact sites between the ER and other organelles. We also review how UPR-dependent connections between the ER and other organelles affect cellular and physiological functions.

Authors: Kaygusuz Meruyert , Gök Cem
Published: September 2018

In this study, fig leaves, zeolite and alginate were used to prepare a biocomposite for the adsorption of Pb(II) ions from aqueous solutions. Effects of various parameters on the biosorption process such as pH, temperature, initial lead concentration and contact time have been investigated. Maximum uptake of Pb(II) ions (85%) has been achieved at pH 6, with 25 mg/L of initial concentration and at a temperature of 288.15 K. Among the applied models, the data correlated well with Freundlich and D-R models and it was established that the biosorption was physical in nature. The amount of adsorbed lead per gram of sorbent was found to be 150.3 mg/g. Thermodynamic parameters showed the exothermic heat of biosorption and the feasibility of the process. Results have suggested that the prepared biosorbent possesses promising biosorption potential.

These diasporic communities actively used social media to “represent” their national identity, to promote their visions of Ukraine’s past and future, and to network and coordinate their actions. This paper argues that the events of the Euromaidan made Ukrainian diasporas in Western countries “re-invent” and “re-imagine” their national belonging. In these processes historical memory, language, and regional identifications play a crucial part within the continuum between conservative ethnonationalist identities and “civic” ones that try to accommodate the ethnic and linguistic diversity of Ukraine in the diasporic setting. This study reveals that “civic” identity elements became more visible across Ukrainian diasporas, but that Russian aggression somewhat haltered the acceptance of diversity and reinforced previously existing conservative sentiments.

Analytical solution for modal analysis of Euler-Bernoulli and Timoshenko beam with an arbitrary varying cross-section
Authors: Sohani Fatemeh , Eipakchi H. R.
Published: October 2018

In this article, the free vibrations of Euler-Bernoulli and Timoshenko beams with arbitrary varying cross-section are investigated analytically using the perturbation technique. The governing equations are linear differential equations with variable coefficients and the Wentzel, Kramers, Brillouin approximation is adopted for solving these eigenvalue equations and determining the natural frequencies and mode shapes. This method relates the solution of equations with the solving of some successive algebraic equations. A parametric study is performed and the effects of different profiles and different combinations of boundary conditions on the natural frequencies are investigated. To confirm the reliability of the present method, the analytical results are checked with those obtained from the finite elements method and other literatures which are found to be in a good agreement. The calculations show that the presented procedure is very effective to find the modal characteristics of the varying cross-sections beams.
Hotelería sostenible, una aproximación a la economía social como factor de competitividad de destinos turísticos
Authors: Rosales Lobo María Alejandra , Morillo Marysela Coromoto
Published: October 2018

Dada la responsabilidad que tiene la hotelería en el consumo de recursos naturales, desde su construcción hasta su funcionamiento y la concienciación que a nivel mundial se viene dando por la conservación ambiental, se han gestado instancias certificadoras que, a través de una serie de indicadores, avalan la sostenibilidad tanto de las instalaciones como de las operaciones y gestión de la actividad hotelera, lo cual se inserta en la visión de la Responsabilidad Social Corporativa (RSC) en la senda de la economía social. El objetivo del presente trabajo es ubicar las prácticas de la hotelería sostenible en el ámbito de la competitividad del sector turístico como ejemplo específico de los agentes de la economía social, partiendo en un primer momento de la vinculación existente entre esta y la RSC, así como la necesaria incorporación de la misma en el turismo a modo de un instrumento competitivo, contexto donde se enmarca la hotelería sostenible como importante integrante del sistema turístico de todo destino y un aporte a la difusión de la argumentación para prácticas responsables. Se concluye que el hotelería sostenible se enmarca en la economía social, por cuanto las ventajas que la misma implica son en beneficio de los propietarios, trabajadores, turistas y las comunidades receptoras; se trata de una puerta de entrada para que el tejido empresarial turístico se incorpore en el modelo de la economía social, no sólo por sus iniciativas respetuosas para con el ambiente natural, social y cultural, sino además por impulsar la incorporación de otras empresas.

Protein Chimera-based Ca2+ Rewiring as a Treatment Modality for Neurodegeneration
Authors: Rajesh Netra Unni , Qudrat Anam
Published: October 2018

Calcium is a versatile signaling molecule; a key regulator of an array of diverse
cellular processes ranging from transcription to motility to apoptosis. It plays a critical role
in neuronal signal transmission and energy metabolism through specialized mechanisms.
Dysregulation of the Ca2+ signaling pathways has been linked to major psychiatric diseases.
Here, we focus on molecular psychiatry, exploring the role of calcium signaling in neurological
disease development and aggravation, specifically in Alzheimer’s and Huntington’s
diseases. Understanding the molecular underpinnings helps us first to identify common
mechanistic patterns, and second to develop targeted therapeutics for symptom alleviation.
Specifically, we propose potential protein-level hallmarks of dysregulation that can
be targeted using calcium-based chimeras (synthetic fusions of unrelated modular proteins)
for localized pharmacotherapy.

Published: September 2018

El objetivo de este estudio fue evaluar el efecto antibacteriano y la citotoxicidad de un adhesivo de uso ortodóncico con nanopartículas de plata (Ag np’s). Se determinó la actividad antimicrobiana mediante una prueba de difusión en disco para Staphylococcus aureus, Escherichia coli, y Enterococcus faecalis a diferentes concentraciones de nanopartículas de plata en un adhesivo ortodóncico. También se evaluó la citotoxicidad de dicho adhesivo al ser incorporadas Ag np’s, mediante el método de mtt. Los resultados mostraron que las bacterias en estudio, S. aureus, E. coli y E. faecalis fueron susceptibles tanto a las Ag np’s como al adhesivo mip ortodóncico adicionado con Ag np’s a concentraciones de 10, 5 y 3 v/v%. 

El efecto antibacteriano de las nanopartículas de plata es dosis dependiente. La citotoxicidad del adhesivo mip ortodóncico en sí mismo exhibe una citotoxidad ligera a moderada, así como al incorporarle las Ag np’s a las concentraciones antes mencionadas. Las nanopartículas incorporadas en el adhesivo de uso ortodóncico muestran efecto antibacterial así como mantienen una citotoxicidad ligera. 
Non-Markovian Quantum Optics with Three-Dimensional State-Dependent Optical Lattices
Authors: González-Tudela A. , Cirac J. I.
Published: October 2018

Quantum emitters coupled to structured photonic reservoirs experience unconventional individual and collective dynamics emerging from the interplay between dimensionality and non-trivial photon energy dispersions. In this work, we systematically study several paradigmatic three dimensional structured baths with qualitative differences in their bath spectral density. We discover non-Markovian individual and collective effects absent in simplified descriptions, such as perfect subradiant states or long-range anisotropic interactions. Furthermore, we show how to implement these models using only cold atoms in state-dependent optical lattices and show how this unconventional dynamics can be observed with these systems.
