Oenological perspective of red wine astringency
Authors: De Freitas Victor 
Published: July 2017

<p><strong>Abstract</strong></p><p>Red wine is a complex matrix and its organoleptic characteristics are affected by a high complexity of wine compounds, namely polyphenols. One of the most important sensations and also a quality attribute of red wine is astringency. Along the years the major mechanism proposed to astringency perception is the interaction and precipitation of salivary proteins (in particular proline-rich proteins) by red wine polyphenols, namely tannins. Furthermore, it is also known that this interaction is affected by other red wine compounds such as carbohydrates.</p><p>The polyphenolic composition of red wine could be modified by modulation of the several oenological steps. Hence, the modulation of oenological steps could allow modulation of astringency and/or astringency sub-qualities. Crucial oenological steps include ripening, maceration and fermentation stabilization (fining), filtration and aging. Along this review, the influence of these oenological processes in wine polyphenolic composition is systematically revised converging in how it affects astringency from an oenological perspective.</p><p> </p>
The development of the effective learning environment by creating an effective teaching in the classroom.
Authors: Prameswari Sanchia Janita , Budiyanto Cucuk 
Published: July 2017

<p>The changes in learning management typically involve the introduction of various alternative learning methods. The development of an effective learning experience requires the modification of conventional learning. Teaching and learning constructively synchronize instructions and assessment toward the desired learning outcomes. Notwithstanding the vast literature on the creation of effective learning, the lack of explanation on how the relationship between effective teaching and effective classroom would likely leave practitioners and academia without a clear guidance on how to operationalize the creation of effective learning in real life. A systematic literature review procedure was conducted upon published papers between 2007 and 2015 in outstanding education journals. This paper contributes to the literature by amassing the knowledge on pedagogical practices in effective learning creation. In addition, to obtain a granular elaboration about the matter, a framework to operationalize the creation of effective learning is suggested. Three aspects compose the framework namely teachers' intrinsic capabilities, educational institution support, and student’s participative involvement. The roles of each party were extracted from the knowledge contained in the reviewed literature.</p><p> </p><p><a href="http://creativecommons.org/licenses/by-sa/4.0/" rel="license"><img src="https://i.creativecommons.org/l/by-sa/4.0/88x31.png" alt="Creative Commons License" /></a><br />This work is licensed under a <a href="http://creativecommons.org/licenses/by-sa/4.0/" rel="license">Creative Commons Attribution-ShareAlike 4.0 International License</a>.</p>
THE CONCEPT OF IMPRESSION MANAGEMENT OF A TEACHER AS SEEN BY STUDENTS
Authors: Kolmogorova L. S. , Spiridonova G. G. 
Published: July 2017

This article presents a topical issue of impression management of the teacher in professional activity. This paper presents the results of the diagnostic study, which was undertaken among Pedagogical University students. The aim of the study was to identify the representation of students about the teacher's selfpresentation. The study describes the findings. There were revealed students’ representations about the teachers’ self-presentation of the older and younger generation, as well as problems of self-presentation experienced by students, characteristics related to composing of culture of the teacher’s self-presentation. Among the characteristics relating to the teacher’s impression management, students single out external (verbal intelligence, behavioral pattern, feeding themselves and form, etc.) and internal ones (politeness, openness, self-awareness, etc.). The conclusions of the authors points at the importance of consideration of representations of students about teacher’s self-presentation in their training, which can be taken into account in higher education. Ignorance of these representations of students in the educational process makes it difficult to establish contact and to solve pedagogical matters for high school teacher, etc.
THE KACHKA-CHULKOV MODERNIZATION ON KOLYWANO-WOSKRESENSK FOUNDRIES (END OF XVIII – FIRST THIRD OF XIX CENTURIES)
Authors: Vedernikov V. V. 
Published: July 2017

The historiography of the non-ferrous metallurgy in Altai at the period of feudalism still remains under the old dogmata influence about crisis of the Russian state serfdom, resulting in the ideas about technical and technological backwardness in Altai. The article features the process of rapid technological growth of mining production in Altai, thus refuting the theses about production crisis or stagnation on Kolywano-Woskresensk foundries. It is demonstrated that the Kachka-Chulkov modernization (named after the two main head officials) was conducted in three spheres at the same time: production, administrative and economical. The main aim of the Kachka-Chulkov modernization was not to get maximal profit but to stabilize production volume on the level of one thousand puds (16.000 kg) of silver per year.

Authors: Krivosheina N. P. , Fedorov A. I. , Kazin E. M. , Sviridova I. A. , Koshko N. N. , Kolomeets M. S. 
Published: July 2017

The article features the analysis of features of physiological adaptation and the rate of physiological development in boys and girls of preparatory kindergarten groups and 1 – 2 grades of grammar school. The analysis points out the differences of neurodynamic indicators, physiological adaptation and the degree of activity of the autonomic nervous system among 6 – 8 year-old boys and girls. It has been found that, regardless of age, boys are characterized by a lower level of development of mental functions, lower balance of processes of excitation and inhibition in the central nervous system, with faster visual-motor response. They are characterized by a higher degree of tension of regulatory mechanisms. Individuals with symptoms of attention deficit and social-psychological deficits are often detected in this group. Girls display neurodynamic indicators that are most optimal for the corresponding age period, a high level of mental functions development; in this group we observed mainly balanced or parasympathetic influence on heart rate and more satisfactory functional state.
THE ACT FRAME: THE INVARIABLE MODEL AND VARIANTS OF ITS ACTUALIZATION
Authors: Bushuyeva L. A. 
Published: July 2017

The article presents the results of the frame analysis of the situations of such acts as “help”, “benefaction”, “heroism”, “exploit”, “prank”, “antic”, “trick”, etc. The research is based on the idea according to which the conceptualization of acts is linked with the invariable frame, which is a structure built by the following elements: aim, action, subject, object, valuation, result. The aim of the paper is to show how the names of the acts represent this invariable frame model of an act. In the analysis of the names of acts and their cognate words in speech it was revealed that the elements of the slots are interrelated and characterize different aspects of the situations of acts. The conclusion was made that in different situations various elements of the invariable frame can come into the focus of attention. The research shows that the frame of act is a complex, multidimensional category, which reflects the world and relations between its elements.
INTERPRETATION OF DEATH IN THE CH. PALAHNIUK’S ARTISTIC WORLD
Authors: Chemezova E. R. 
Published: July 2017

The article is devoted to the interpretation of the phenomenon of death in contemporary American literature on the example of Ch. Palahniuk’s novels. The article analyzes the approaches to the phenomenon of death in different fields of knowledge such as philosophy, sociology, medicine. We describe the overview of the “life after death” theme in native and foreign literature. The place of the phenomenon of death in the artistic world and the influence of this phenomenon on the attitude of the characters to each other are in the focus of our attention. Death in the artistic world defines the characters’ relations, their presence / absence on different levels of the artistic world, the process of transition from the world of the living to the world of the dead and vice versa. The process of heroes’ formation in the world of the living and in the world of the dead depends on the representation of the phenomenon of death in the works of Ch. Palahniuk. The boundary between the world of the living and the world of the dead is almost invisible and the transition between the worlds is done according to certain laws of the art world, followed by the characters of the novels. This article discusses several Ch. Palahniuk’s novels written in different periods of his oeuvre. The article examines the differences and similarities in the author's interpretation of the death and its significance in the early (“Fight Club”, “Lullaby”) and the latest (“Damned”, “Doomed”) novels. In the early novels of Charles Palahniuk death is a physiological process with anatomical details, but at the same time dying is the soul leaving the body. The latest novels of the author differ from the early ones as they demonstrate to the reader not only the life and its ending, but also the life after death.

Authors: Onischenko S. S. , Shirin Y. V. 
Published: July 2017

The article presents the analysis of faunal collections obtained during the excavation of the Kuznetsk in 2012 and dated to the XVII – XVIII centuries. There were studied 1534 remains of domestic and wild mammals, birds and fish. The result shows the similarities and differences in the structure of asynchronous zooarchaeological assemblage, synchronous of household buildings and cultural layers outside, peculiarities of formation of bone-bearing sediments at different sites and zoogenic impact on these processes. As for animal remains, cows and pigs prevailed; as for fish, the leading role belonged to the sturgeon. It is assumed that the main elements of the economic structure of the settlers were house cattle breeding, fishing and occasionally hunting for moose, bear, fox, hare, and wild birds. The settlers also had dogs, cats, sheep, horses, chicken. The analysis results are discussed in the context of distinctions of life of separate microsocieties, vertical and horizontal relocation of bone residues and their transformation.

Authors: Yousef A. I. , Akhtyamov I. F. 
Published: July 2017

The paper represents a review of modern foreign literature dedicated to joint replacement in patients with increased body mass index. The authors examine the epidemiology, pathogenesis features of osteoarthritis (arthrosis) in obesity. The majority of experts consider the increased body mass index an aggravating factor in the surgical treatment of large joints arthrosis. There is also the opposite point of view, confirmed by many orthopedic surgeons.The analysis of publications in foreign scientific literature regarding the risk of intraand postoperative complications after arthroplasty in obese patients yields controversial results. The authors regret availability of only a few studies on such an interesting and important topic carried out in Russia. The need for a detailed study of the issues related to treatment of patients with obesity is prompted by our time.

El cuerpo por sí mismo. De la fenomenología del cuerpo a la ontología del ser corporal
Authors: Ramírez Cobián Mario Teodoro 
Published: July 2017

<p>Recibido: 29/08/2016 • Aceptado: 02/02/2017</p><p> </p><p>Este trabajo pondera el «giro corporal» de la filosofía del siglo XX. Parte de la revaloración que hace Nietzsche del cuerpo frente a una tradición que ha enfatizado tal vez demasiado la espiritualidad del alma, despojándola del cuerpo. Una «filosofía del cuerpo» correctamente planteada bien podría devolvernos la plebeya realidad que el criticismo moderno tanto alejó. Para poder ofrecer una salida al solipsimo universal, sería precisa, pues, una filosofía del cuerpo capaz de replantear el realismo. Así, se presenta los abordajes de de Merlau-Ponty y Jean-Luc Nancy hacia una filosofía de lo corporal y de la carne, respectivamente. La siguiente sección se dedica a presentar las consecuencias del giro corporal de la filosofía respecto de la ontología: presenta el trayecto del cuerpo al Ser. El carácter de exterioridad ejemplar con el que Nancy define al cuerpo nos permite calibrar –en el sentido de una filosofía inmanentista no cerrada ni definitiva– un ateísmo no ingenuo y un realismo ontológico no abstracto ni dogmático. Para concluir el ciclo, se propone el camino que ha planteado el «nuevo realismo», defendido por Markus Gabriel, Ferraris, Harman y otros. La intención de este trabajo es presentar cómo sería posible formular la nueva Ontología, la nueva concepción del ser y la existencia, una ontología materialista, realista, tanto del ser extracorporal como del ser corporal.</p>

In this paper, first the overall modeling approach
for an optimized control of a hot-gas cycle for solar thermal
power plants in the Modelica language is pointed out. The
emphasis of the modeling work lies on the development of
dynamic component models to be used in control systems.
Depending on the control task, the discretization of the models
has to be adapted. Main components of the hot-gas cycle are the
solar thermal receiver and the storage system. The steam cycle
is preliminarily only included as heat sink.

Second, for control purposes a linear model-based controller
(MPC) was implemented in Modelica based on an external
state-of-the-art QP solver [2] linked to the Modelica model. The
performance of the MPC is compared with a basic automation
scheme based on classical PID controllers.
Operating an electric motor in saturation – mechanical vibrations and other effects
Authors: F. Oliveira  , M. P. Donsión  , Jan Iwaszkiewicz  , Jacek Perz  
Published: July 2017

This paper addresses some of the effects of running an electric motor near and in the saturation zone of the electromagnetic hysteresis curve, namely mechanical effects such as mechanical vibrations and rotation speed apart from the classic electrical and thermal effects. Mechanical vibrations are intrinsically characteristic of rotating machines, and other turbomachine characteristics, such as rotor unbalance, non-linearity and shaft variable stiffness can introduce severe disturbances in the operation of the machine. Rotation speed is also affected by electric parameters, when the mechanical machine is connect to an electric machine, meaning both the electric machine type and the process by which it is driven affects both the value of speed and its constancy.
New module integrated multilevel inverter for grid connection of photovoltaic plants
Authors: G. Mehlmann  , G. Herold  
Published: July 2017

This paper presents a new solar multilevel inver-ter, based on the cascaded-multilevel converter. The main idea is that the new inverter generates a so called “highly pulsating space phasor” instead of a reference voltage. This operation mode limits the distortions. Additionally, for the first time energy redundancies between the voltage levels can be used, instead of the so far known voltage redundancies. As a result, the problem of unbalanced voltage sources can be avoided, a complex control is not necessary anymore and the MPP track-ing of solar multilevel inverters can be improved considerably.
Investigation of Line-Commutated Three-Phase Converters Under Voltage Unbalance
Authors: Manuel Weiland  , Gerhard Herold  
Published: July 2017

Power converters operated in unsymmetrical three-phase elec-trical systems will generally work asymmetrically. This intro-duces disadvantages for the operation of the electrical power system, like non-characteristic harmonics. In the case of con-trollable power converters, such as thyristor converters, it is possible to operate the converter with asymmetrical firing an-gles. This offers the opportunity to react on the system’s unbal-ance optimizing the asymmetrical operation of the converter to lower the disadvantages. In this paper, a method is presented to calculate the behaviour of electrical equipment based on line-commutated current con-verters. Thereby, the operation of the essentially non-linear system is described as sectional continuous linear problem. For its solution an approach with differential equations in the range of space-phasors is used. It is shown to be possible to optimize the unsymmetrical operation with respect to certain quality criteria by using unsymmetrical firing angles.
Advanced Voltage Positive Feedback Control for Anti-islanding of a Distribution Generation Inverter
Authors: S.-K. Kim  , J.-H. Jeon  , H.-K. Choi  
Published: July 2017

the paper discusses an analytical design of dq-based voltage positive feedback (VPF) control for anti-islanding of a distributed generation (DG) inverter. Design criteria for the voltage feedback gain are presented. Based on small signal stability and step response analysis, an analytical design method for lower and upper bounds of the gain is described. It is proven that conventional VPF gain is significantly influenced by real power levels of a DG. To improve this weakness, a modified VPF is proposed. Simulation study validates the analytical design method and the modified VPF control performance for a constant power- controlled inverters.

Authors: Ferreira Arquez Humberto 
Published: July 2017

Background: The present study documents valuable new data on the anatomical variations of the musculus flexor digitorum brevis in an adult Colombian population, this muscle and in particular its fourth slip, has a significant clinical and surgical importance. The fourth slip is undergoing a phylogenetic degeneration. The purpose of this study is to conduct an evidenced on the prevalence of the musculus flexor digitorum brevis and its variants in humans.
Methods and Findings: A total of 17 cadavers with different age groups were used for this study, 34 feet of 15 male and 2 females embalmed adults cadavers in the laboratory of Morphology of the University of Pamplona. All feet (n= 34) were studied serially during the years 2013-2016. Of the 34 feet examined, in 32 (94.12%) the muscle conformed to the classical descriptions given in anatomical textbooks showed 4 bellies. In the remaining 2 feet (5.88%) the muscle divided into three parts which ended in slender tendons to the second, third and fourth toes.
Conclusions: The knowledge of the anatomical variations in relation to the demographic characteristics of patients would be of importance for diagnostic imaging and foot surgery.
