Published: July 2018

The successes of modern surgery of wounds are impossible without understanding the changes in intercellular and cell-matrix interactions, in this connection the latest data on the role of mast cells in various pathological states deserve special attention. Mast cells play a key role in tissue repair. Their maximum representation is found in the skin, mucous membranes of the respiratory system, gastrointestinal tract. Mast cells are activated immediately after skin damage and are involved in all phases of the wound process. When tissue damage or adverse effects from mast cells are released, a whole arsenal of inflammatory mediators, proteases, growth factors that trigger a cascade of reactions, including the inflammatory process. Serine proteases efficiently remodel elements of the extracellular matrix, which is necessary for the transition to the next stage of wound healing. The multifunctionality of mast cells is manifested by the release of both proinflammatory and anti-inflammatory and immunosuppressive cytokines, which is an important clinical aspect, since an incorrect treatment tactic contributes to the chronic wound process. Synthesis of collagen by fibroblasts and angiogenesis are the result of complex molecular-cell events with the direct involvement of mast cells. In the late stages of the wound process during re-epithelialization, their mediators can stimulate keratinocytes to restore the epidermal barrier. Studying the effects of mast cells with slow regeneration due to diabetes mellitus, ischemia, tissue denervation, and microcirculation disturbance opens up prospects in the treatment of long-term non-healing wounds with socially significant diseases. Thus, already known data and further fundamental studies of mast cells allow us to consider them as a biomarker of the dynamics and severity of the wound process, and as a target for regulating the wound process at different stages.
Implementing global citizenship education in EU primary schools: The role of government ministries
Authors: Tarozzi Massimiliano , Inguaggiato Carla
Published: July 2018

According to recommendations of the UN Secretary General's Global Education First Initiative, countries and regions require a number of structural changes if they are to implement educational policies and practice based on global citizenship education, and to promote respect and responsibility
across cultures. In this paper, we present the first results of a three-year project to compare existing educational policies, strategies and school curricula in ten European Union (EU) countries (Austria, Bulgaria, Czech Republic, France, Ireland, Italy, Latvia, Spain, Portugal, UK) to ascertain
the current level of such structural changes. Through a comparative policy analysis, we investigated whether, to what extent, and how global citizenship education is integrated within primary school curricula. The article focuses on national governmental agencies – specifically two main
bodies in each country, the ministries of foreign affairs and education – and their political discourses. We argue that the gap between the two traditions, with separate approaches, purposes, concepts and bureaucracies, represents a strategic political challenge for the introduction
of global citizenship education in primary schools.
Enhanced Power Quality Compensation of Shunt Active Power Filters Without Harmonic Detection Schemes
Authors: Ribeiro Ricardo L. A. , Sousa Raphaell. M. , Dos Santos Jr. Euzeli C. , Rocha Thiago O. A.
Published: July 2018

Shunt active power filters (SAP F) implemented without harmonic detection schemes compensate simultaneously harmonic distortion and reactive power of the load. Their compensation capabilities, however, are limited by the SAP F power converter rating. Such a restriction can be minimized if the level of the reactive power correction is managed. An estimation scheme for determining the filter currents is introduced to manage the compensation of reactive power. The effectiveness of the proposed control strategy is ensured by introducing a feedforward scheme on the DC − link regulation. Also, a robust control based on adaptive pole placement regulates the grid currents. Experimental results are shown for demonstrating the performance of the proposed SAP F system.

Published: July 2018

This paper presents the study and implementation of a hybrid position controller for an indirect field-oriented induction motor drive. In order to improve the position tracking performance of an induction motor drive, a design procedure of a hybrid controller is developed based on the conventional Proportional (P) controller and the Generalized Predictive Control (GPC) controller. The fuzzy logic is utilized to achieve the hybridization between the P and GPC controllers. The P is adopted because its parameter values can be simple chosen with an aggressive tuning (fast response), while the GPC controller enhances the robustness and has a moderate controller action. Then, the position control loop is regulated with the hybrid controller, while the speed and currents loops incorporate PI (Proportional Integral) controllers. The proposed controller, simulations, implementation data, and test results with step, trapezoidal, triangular position profiles and step change in load, are given, discussed and verified. It is shown that the proposed position hybrid controller has a fast tracking capability to industrial robotics applications and it is robust to load disturbance.

Published: July 2018

Este artigo apresenta uma comparação entre quatro algoritmos para a compensação do conteúdo harmônico e da potência reativa através de condicionadores de energia. Os quatro algoritmos testados são: o método da referência síncrona, o filtro adaptativo sintonizado utilizando o PLL para gerar os sinais de referência, o filtro adaptativo sintonizado utilizando a Transformada de Clarke para gerar os sinais de referência e o filtro adaptativo sintonizado com estimador de frequência. O principal objetivo é demonstrar a habilidade dos filtros adaptativos em acompanhar as variações do sinal de entrada, sem a necessidade de um algoritmo de sincronismo, como o PLL. Os algoritmos foram simulados, implantados no DSP TMS320F2812 e testados diretamente em filtros ativos de potência. Diversos aspectos relativos ao tempo de execução, à velocidade de convergência e ao erro em regime permanente são apresentados.
Grid-tie Three-phase Inverter With Active and Reactive Power Flow Control Capability
Authors: Sampaio Leonardo P. , De Brito Moacyr A. G. , E Melo Guilherme de A. , Canesin Carlos A.
Published: July 2018

This paper proposes a methodology for the active and reactive power flow control, applied to a low voltage grid-tie three-phase power inverter. The control technique is designed by means of feedback linearization and the pole placement is obtained using Linear Matrix Inequalities (LMIs) together with D-stability concepts. Through multi-loop control, the power loop uses adapted active and reactive power transfer expressions, in order to obtain the magnitude of the voltage and the power transfer angle to control the power flow between the distributed generation (DG) and the utility grid. The state-feedback linearization technique is applied at the whole control system in order to minimize the nonlinearities of the system, improving the controller's performance and mitigating potential disturbances. The methodology main idea is to obtain the best controllers with the lowest gains as possible placing the poles in the left-half s-plane region specified during the design procedure, resulting in fast responses with reduced oscillations. Demonstrating the feasibility of the proposal a 3kVA three-phase prototype was experimentally implemented. Furthermore, experimental results demonstrate anti-islanding detection and protection against over/under voltage and frequency deviations.

Published: July 2018

The recent development of higher blocking voltage gallium nitride (GaN) power FETs has the potential to enhance the power density of future power electronic converters. However, the new generation power semiconductors create new challenges to Power Electronics design that include: circuit layout to reduce parasitics, very high frequency digital control implementation, electromagnetic compatibility, passive components design, among others. In this work, GaN devices are used to assemble a 100 W single-phase two-channel interleaved boost-type power factor correction converter in order to evaluate some of the GaN devices challenges. The constructed hardware is able to operate with a switching frequency up to 1 MHz per channel, and hence a 2 MHz effective ripple frequency at the input and output terminals of the interleaved system. Furthermore, in order to cope with the high frequency requirements an average current mode control strategy is implemented in an FPGA device. Finally, experimental results verify the feasibility of the developed digital feedback control scheme and laboratory prototype.
Isolated Single-phase High Power Factor Rectifier Using Zeta Converter Operating in DCM With Non-Dissipative Snubber
Authors: Callegaro Alan D. , Martins Denizar C. , Barbi Ivo
Published: July 2018

This paper presents the study of a single-stage, single-phase, unity power factor converter, isolated by a high frequency transformer, based on a Zeta converter operating in discontinuous conduction mode (DCM). The main feature of the proposed converter is its ability to naturally emulate an apparent resistance to the ac input source, without current sensor or current controller. Circuit operation, theoretical analysis and design example are included in this paper, along with experimental results taken from a laboratory prototype rated at 400W, input voltage equal to 127 V, output voltage equal to 200 V, switching frequency of 25 kHz and efficiency of 92 %. In order to reduce the commutation losses and limit the peak voltage across the power semiconductors, a non- dissipative snubber has been included in the laboratory prototype. With the advent of new low losses power semiconductor technologies, such as SiC and GaN, power converters operating in DCM will become very attractive, due to their simplicity and robustness, even for high power applications. This is the main motivation of the study presented hereafter.

Authors: Da Silva Sérgio A. Oliveira , Campanhol Leonardo B. G. , Bacon Vinícius D. , Sampaio Leonardo P.
Published: July 2018

This paper deals with an alternative current reference generator algorithm proposition, which is employed to inject active power into the grid and, simultaneously, performs reactive power compensation and load harmonic current suppression in single-phase grid-connected photovoltaic (PV) systems. The PV system reference current is computed based on synchronous reference frame method, which operates in conjunction with the dc-bus controller. In addition, by adopting a proper strategy, it is proposed criteria for establishing the priority on the power compensation by the PV system, in order that the power rating of the gridconnected PWM converter is not exceeded. The Perturband-Observe maximum power point tracking technique is employed to generate the dc-bus voltage reference for extracting the maximum power from the photovoltaic array and, therefore, maximizing its efficiency. Both simulation and experimental results are presented to verify the static and dynamic behaviors of the grid-tied photovoltaic system, as well as evaluate its performance.

Authors: Burgardt Ismael , Agostini Jr. Eloi , Font Carlos H. Illa , Nascimento Claudinor B.
Published: July 2018

This paper presents an AC electronic lighting system using a non-isolated SEPIC PFC rectifier to drive and control power LEDs currents. One energy regenerative snubber for reducing the converter switching losses and improve the system efficiency is proposed. To reduce ripple current in the LEDs array a linear current regulator is placed in the SEPIC’s output terminals. In order to reduce the efficiency impairment, the conditions for achieving minimum energy loss in the current regulator are also detailed. The operation stages as well as the theoretical waveforms and main equations at steady state of the proposed SEPIC rectifier using a regenerative snubber are detailed. To verify the theoretical analysis carried out, experimental results of a prototype operating in 127 and 220 V for 35 LEDs / 42 W are also presented. In this paper, the point of minimum energy loss in the linear regulator is adjusted in open loop to validate the converter operation.
Analysis of the Magnetizing Inductance Influence on Current Stresses of the Wide-zvs-range Asymmetrical Half-Bridge Converter
Authors: Font Carlos Henrique Illa , Agostini Junior Eloi
Published: July 2018

This paper presents the analysis of the magnetizing inductance influence on the current stresses of the asymmetrical half-bridge (ASHB) DC-DC converter power stage components. One solution for extending the soft-switching operating range is to reduce the magnetizing inductance, which has the collateral effect of increasing the converter’s conduction losses. Hence, in order to meet trade-off requirements of high efficiency at light load with minimum heavy load conduction loss penalty, the impact of magnetizing inductance value on the ASHB converter current stresses is quantified. A 500 W, 300 V input, 60 V output, 50 kHz laboratory prototype is built to verify the ZVS-range operation and efficiency penalty for several values of magnetizing inductance.
Design of Loosely Coupled Magnetic Systems Based on Finite Element Method for Inductive Power Transfer Applications
Authors: Fernandes Rodolfo Castanho , De Oliveira Jr. Azauri Albano
Published: July 2018

This paper proposes an iterative approach for the design of loosely coupled inductors for inductive power transfer applications. The procedure is based on the finite element method and is suitable for realistic coil geometry development where non-linear magnetic materials are required. Dedicated algorithms represent self-inductances and mutual inductances in terms of equivalent geometric parameters and vice-versa thus allowing an approach that is not possible in analytical formulations. Also, finite element method is used to analyze the coil system, with two or more coils, under axial, lateral and angular misalignment prior to the development of prototypes. The iterative method can be used to support development of wireless power converters for biomedical implants, electric vehicles recharging systems and chargers for portable devices, with simple and minor modifications. Also, it has specific tools for geometry optimization that can lead to maximized power transfer. Experimental results are presented for coupling coefficient under spatial misalignment.

Published: July 2018

Exploiting the flux concentration configuration is a good alternative for designing a relatively low cost synchronous motor based on ferrite magnets. This paper discusses the design of a motor drive system based on a three-phase permanent magnet motor in which both the use of low cost ferrite and minimization of cogging torque have been adopted as design criteria. The dynamic modeling, parameter identification, and experimental characterization of the motor as well as the overall control system design have been performed. Simulation and experimental results are presented to demonstrate the correctness of the methodology and the feasibility of proposed motor drive solution and its related feedback control laws.

Published: July 2018

This paper presents two AC machine drive systems based on three-phase to five-phase ACAC converters and open-end winding five-phase machine. The drive systems are suitable for applications in which high power, performance and reliability are required using low power and voltage switches and low DC-link capacitor voltages. The configuration I employs an input transformer with two secondary taps at the grid side, two three-phase three-leg converters and one tenleg converter (totaling sixteen legs). The configuration II employs a low-power series transformer at the grid side, two three-phase three-leg converters, and one ten-leg converter. Both configurations permit to reduce the power and voltage ratings of power switches and also the DClink capacitor size. The paper presents the comprehensive models of the proposed systems, modulation strategies and a general comparison with the conventional configuration. Simulated and experimental results are presented.
USE OF INTERSPECIFIC HYBRIDIZATION IN THE BREEDING OF ADAPTIVE HYBRIDS AND SORTS OF GARDEN CHRYSANTHEMUM (Chrysanthemum morifolium Ramat.)
Authors: Nedoluzhko A. I.
Published: July 2018

Many garden chrysanthemums bred across the world are not fully winter hardy. Many are damaged by fungal diseases due to a high humidity and are late flowering. This makes them unsuitable for general commercial marketing. Since 2000 we have been conducting a breeding program using natural species of the genus Chrysanthemum that are adapted to the local conditions. The strategy of breeding adaptive hybrids and varieties of chrysanthemum native to Russia was proposed based on their biological, genetic peculiarities and natural resources of Chrysanthemum with the use of interspecific hybridization. Research objects are the first generations of interspecific hyb rids of F1obtained previously by the author as a result of the hybridization of varieties and wild species of Chrysanthemum. Derived from different species and varieties, F1hybrids were crossed among themselves to obtain the multicomponent F2progeny. F2seedlings with winter hardiness, resistance to Puccinia horiana Henn. and early flowering were used in closely related crosses. The offspring of F3from closely related crosses were also assessed and selected according to adaptive and decorative characteristics. Inclusion in the selection process of various sources of winter hardiness and resistance to P. horiana allowed positive characteristics to be increased in F2and to be revealed in F3. Adaptive signs of the wild species Chrysanthemum naktongense Nakai, C. coreanum (H. Lév. et Vaniot) Nakai, C. zawadzkii var. tenuisectum Kitag., C. leiophyllum Nakai, and C. zawadzkii subsp. acutilobum (DC.) Kitag., which have formed and fixed during evolution, were inherited and manifested in offspring of the multicomponent hybrids and the closely related crosses. Promising interspecific forms with biological signs determining the possibility of growing in extreme conditions of the subregion were selected.
O desafio do Timor-Leste atual: em busca de uma identidade nacional ligada à língua portuguesa
Authors: Maia Helio José Santos , Carneiro Maria Helena da Silva
Published: July 2018

Produto de extensa pesquisa sobre educação em Timor-Leste, este artigo apresenta um recorte sobre os desafios da implantação da língua portuguesa naquele país, que a colocou como língua oficial de instrução na sua Constituição. O Timor é considerado um país transcontinental por apresentar seus domínios tanto no continente asiático, em sua porção norte, sob a influência do Pacífico, quanto na Oceania, em sua porção sul, ligada ao Oceano Índico. Antiga colônia portuguesa, provavelmente a menos prestigiada do Império Português ultramar, possui uma história eivada de desafios em busca de sua autonomia como nação. O objetivo do trabalho é apresentar, por meio das narrativas de antigos governadores portugueses no Timor do período colonial, Afonso de Castro (1824-1885) e Teófilo Duarte (1898-1958), as dificuldades do empreendimento colonial português naquelas terras frente à pluralidade linguística e cultural delas, ao espírito arredio dos seus habitantes em relação ao domínio português e aos obstáculos, conferidos pela distância da metrópole, para implantação definitiva da empresa colonial. Para isso, empreendeu-se pesquisa bibliográfica a livros e documentos na Biblioteca do Programa de Pós-Graduação e Pesquisa (PPGP) da Universidade Nacional de Timor Lorosa’e (UNTL), em Díli, Timor-Leste, assim como à Biblioteca do Instituto Nacional de Formação de Docentes e Profissionais da Educação (Infordepe), e entrevistas a professores, a formadores de professores e a estudantes no país. Como resultados, é possível identificar a dificuldade na implantação da língua portuguesa pela via educacional, em função da ausência de imersão nessa língua no espaço escolar, da grande oferta de línguas maternas para a comunicação cotidiana, do fortalecimento do movimento pela implantação de línguas maternas na escolarização inicial das crianças, ao mesmo tempo em que aponta a possibilidade de aquisição da língua portuguesa por seu povo pelo alcance do ciclo completo de escolarização até o nível superior.

Durante décadas, Goa era um assunto esquecido ou marginal nos estudos que procuraram rever a história colonial e mapear os desenvolvimentos da descolonização europeia. Mas, na transição para o século XXI, Goa tornou-se o objecto de estudo de vários projectos de investigação e é temática cada vez mais conhecida. Por quê? E o que se tem concluído de diversos estudos sobre esse pequeno mas intrigante estado? A minha contribuição pretende oferecer uma visão do estado da arte relativa aos estudos sobre Goa, sublinhando as principais conclusões e o interesse dessas mesmas conclusões para os estudos sobre as dinâmicas sociopolíticas e culturais do Oceano Índico. Em segundo lugar, e dada a existência de várias línguas oficiais em Goa (konkani, marata e inglês), qual o lugar da herança cultural portuguesa e qual é o actual enquadramento dos estudos da literatura goesa em língua portuguesa?

A novel technique based on the Law of Comparative Judgment for quality-related problems
Authors: Franceschini Fiorenzo , Maisano Domenico Augusto
Published: July 2018

A relatively diffused problem in the quality engineering/management field is that in which a set of judges express their individual (subjective) judgments on a specific attribute of some objects and these judgments have to be fused into a collective one.

The goal of this paper is to develop a new technique that combines the Thurstone’s Law of Comparative Judgment with an ad hoc response mode based on preference orderings. This technique allows to express the collective judgment of the objects on a ratio scale and is applicable to a variety of practical contexts.
Positional uncertainty in optical-based metrology systems in large volume manufacturing
Authors: Miller Ainsley , Mulholland Anthony J , Pierce Stephen Gareth , Hughes Ben , Forbes Alistair B
Published: July 2018

Modern manufacturing increasingly utilizes automated systems for component positioning and assembly and a vital aspect of autonomous precision manufacturing is large volume metrology. One popular approach uses light rays, which travel through the volume of air, to calculate the position of an object of interest. These optical-based metrology systems such as photogrammetry and laser tracking are crucial in improving the accuracy and quality associated with robotic assembly. However, in an industrial setting, these positional measurement systems give rise to uncertainties which can in many instances be greater than the required tolerances. One source of this uncertainty is light refraction due (in part) to temperature fluctuations in the air. This paper will describe how COMSOL Multiphysics can be used to create simulated data with complete ground truth on the refractive index field in the volume, and will discuss the measurement uncertainties associated with these simulations. Over industry relevant distances (tens of metres) the uncertainty in the position measurement due to light refraction is of the order of a millimetre.

Although the principle is as such nothing new to metrology and testing laboratories, which carry out experimental measurements, a degree of clarification is nonetheless called for in view of the numerous questions that arise concerning ways of implementing and utilizing it to improve knowledge capitalization.

The acquisition of knowledge relative to any measurand involves a series of steps: studying the state of knowledge of the measurand, choosing a working method (typically, by establishing a design of experiment), obtaining the measurements, and analyzing them. Following this, an action plan is established in order to reduce (or if possible avoid) weaknesses or over sensitivity.
Comparisons are already conducted using various approaches within a laboratory. It is therefore important to understand that to assess the accuracy of a method and validate it, it is necessary to compare the results obtained by several laboratories for a given method and measurand with the correct type of inter-comparison. It is this comparison between several laboratories that, when using different methods, produces the most up to date knowledge with the highest confidence level. This paper goes over the steps that allow developing knowledge, presenting the aims and characteristics of the various inter-laboratory comparison methods, notably referring to the tools established by documents such as the BIPM MRA (the Mutual Recognition Arrangement), the ISO 5725 and the ISO 13528.

THE RANGE OF ADMINISTRATIVE JUSTICE SPECIALIZATIONS IN RUSSIA AND THE OTHER BRICS COUNTRIES
Authors: Kleandrov M. , Pluzhnik I
Published: July 2018

This article deals with the challenges concerning increasing administrative justice efficacy in Russia and other BRICS countries, where the specialized development of jurisdictional bodies is inconsistent and far from effective. The article analyzes the gaps and disputed aspects of administrative justice including the mechanisms for judicial administrative dispute resolution in the BRICS countries. The authors argue that the level of effectiveness of administrative justice vested in judicial procedures depends critically on the specialization of the administrative courts. This involves individual judges, separately operating permanent judges, judicial committees, mono-courts, independent administrative judicial systems incorporated into larger judicial systems within the courts of general jurisdiction, and separate and independent administrative and judicial systems. Even though the BRICS countries do not have a structured administrative judiciary, the retrospective and comparative analysis of their administrative justice jurisdiction and its most effective practices and mechanisms undertaken by the authors enables them to rethink the existing approach to resolving administrative cases via the judiciary. The aim of the article is to initiate the creation of an independent administrative court system organization in order to ensure better justice in the areas of social life including legal relations with executive bodies. Suggestions for the implementation of the specialization of the administrative judiciary in the Russian Federation are given. The authors, for the first time in Russian jurisprudence, propose a theoretical model of an independent, four-tiered specialized legal mechanism of administrative justice, which includes the interrelated factors of court organization, the judiciary and their legal status. The range of the four specialized tiers of the administrative judicial system is proposed. It is argued that they should include a systematic succession represented by lower courts, first instance lower courts, area courts and a Higher Administrative Court of the Russian Federation.

Authors: Liu Wei , Jiang Xiwen , Liu Yue , Ma Qingsong
Published: July 2018

Objective:

This research aimed to make comparisons of sensitivity and specificity between Quantitative real Time Polymerase Chain Reaction (Q-PCR) and Reverse Transcription PCR (RT-PCR) in detecting the ribonucleic acid (RNA) expression levels of Hepatitis C Virus (HCV).

Methods:

121 patients suffering from hepatitis C and 98 healthy participants with normal liver functions were identified. The venous blood collections were carried out, were subjected to detect the expression levels of HCV RNA via Q-PCR and RT-PCR. And then, the data obtained from these above two detection methods were compared, including the sensitivity and specificity.

Results:

In terms of Q-PCR, the positive rate of HCV RNA was 72.16%, which was significantly higher when compared with 55.26% of RT-PCR. After statistical analysis, the difference between them was statistically significant (P＜0.05). Among the healthy participants, 4 cases were false positive by means of RT-PCR, there was the possibility of missed diagnosis when the samples were evaluated by Q-PCR.

Conclusion:

: The Q-PCR detection technology performed well in testing HCV, with pretty high sensitivity and specificity. Nevertheless, the false negative results obtained from Q-PCR could not be avoided. In clinical practice, these above two detection methods should be referred to, in order to avoid missed diagnosis.
