Authors: Smirnova Y.K.
Published: December 2018

The article reveals the provisions that speech is used by preschool children in joint activities as a means of orientation in the process of developing an action plan. The goal was to identify the role of speech in the implementation of the exploratory search activity of the members of the group in the course of joint activities, as well as to develop control over the actions of preschool children. The study involved 147 preschool children, who were organized during the experiment in subgroups to jointly solve problematic situations. To illustrate the approximate role of speech in regulating the joint activity of preschoolers, Structural Equations (SEM) modeling was applied. A model is constructed that reflects the combined functional links of the regulation of the joint activity of preschool children. It is proved that in the structure of the regulation of joint activity speech provides an afferent synthesis of the conditions of activity, facilitates the analysis of internal and external conditions of joint activity, the development of a program of conscientious activity. It is shown that for preschool children, speech orientation tools are used as a mechanism for controlling and correcting behavior.

Accuracy of Satellite-Based Solar Data to Estimate Solar Energy Potential for Hatay Province, Turkey
Authors: ÖZBULDU Mustafa , İRVEM Ahmet
Published: December 2018

Solar radiation data is important parameter to estimate
solar energy which is a major renewable energy in terms of sustainable
resources. Accurate spatial and temporal distribution of solar radiation is
required not only to estimate solar energy but also hydrological,
meteorological and climatological studies. General objective of the study is to
examine accuracy of freely available Climate Forecast System Reanalysis (CFSR)
solar radiation data against ground observation data based on monthly and
yearly averages over the Hatay province in Turkey. The CFSR dataset including
25 daily solar radiation measurement points was evaluated against 12 ground
stations for 21-year period (1985 - 2006). Statistical results showed that most
correlations in monthly basis data were weakly correlated except October (R2=0.73).
According to results of Bias, CFSR monthly averaged solar energy was over
estimated for all months. Also, CFSR annual solar energy 28% higher than ground-based
observed solar energy with R2=0.76. Annual CFSR solar energy found
between 5.2 and 5.6 kWh m-2day-1.
Annual ground-based solar energy ranged from 3.9 to 4.2 kWh m-2day-1.
The result showed that, it is unacceptable to use the CFSR dataset in case of
lack of measured values of ground-based solar radiation in monthly and yearly
averaged basis. Estimated CFSR data has need to be improved and accuracy of
CFSR data must be tested for other regions in Turkey. We recommend finding
another source of satellite-based data to compare with ground-based data.

Current mode performance of a traction linear induction motor driven from the voltage converter
Authors: Palka Ryszard , Woronowicz Konrad , Kotwas Jan
Published: December 2018

Background: The paper deals with the modelling of a traction Linear Induction Motor (LIM) for public transportation. Typical problems arising from the electromagnetic finite element model development are described. The end effect causes asymmetry of phase impedances of the LIM. Because of that, if the LIM is supplied from the voltage inverter, which is usually the case, the phase currents become asymmetric. This causes performance calculation discrepancies in models that assume phase current symmetry.
Aim: The aim of the paper is to develop a method for calculating the imbalanced three-phase LIM currents to precisely predict the LIM performance.
Methods: Here, a method is developed to calculate the LIM phase current asymmetry by means of a self-developed electromagnetic finite element program – ELMAG, capable of adapting mesh generation based on Reynolds, Péclet and skin-depth numbers.
Results: The calculated asymmetric currents are used in a real size traction LIM calculation in COMSOL, to derive the performance characteristics for comparison with the results achieved when supplying the LLIM with the symmetric three phase current.
Conclusion: These results show that the natural asymmetry of the currents is an important factor that must be considered in appropriately calculating the LIM performance.
Energy consumption of track-based high-speed trains: maglev systems in comparison with wheel-rail systems
Authors: Fritz Eckert , Blow Larry , Kluhspies Johannes , Kircher Roland , Witt Michael H.
Published: December 2018

Background: The energy consumption of a high-speed system is an important part of its total operational costs. This paper compares the secondary energy demand of different wheel-rail systems, such as ICE, TGV and Shinkansen, and maglev systems, such as Transrapid and Chuo Shinkansen.
In the past, energy values of systems with different conditions (train configuration, dimension, capacity, maximum speed) were frequently compared. The comparative values were often represented by the specific energy consumption based on passenger capacity and line-kilometer values.
Aim: The goal is to find a way to compare the specific energy consumption of different high-speed systems without any distortion of results.
Methods: A comparison of energy values based on normative usable areas inside the high-speed systems will be described and evaluated in this paper, transforming the results to a more distortion-free comparison of energy consumption of different systems.
Results: The results show the energy consumption as an important characteristic parameter of high-speed transportation systems based on an objective comparison and give ranges of expected energy demand of different systems dependent on maximum speed level.
Conclusion: Up to the design speed of wheel-rail systems there are slight advantages in terms of energy consumption for the Transrapid maglev. From the perspective of energy consumption under consideration to reduce travel time, high-speed maglev systems represent a promising option for new railway projects. However, a project-specific system decision must be based on a complete life-cycle cost analysis, including investment cost

Constant switching frequency model predictive control for permanent magnet linear synchronous motor
Authors: Ma Zhixun , Zhao Yuanzhe , Sun Yan , Liao Zhiming , Lin Guobin
Published: December 2018

Aim: This paper proposes constant switching frequency model predictive control (CSF-MPC) for a permanent magnet linear synchronous motor (PMLSM) to improve the steady state and dynamic performance of the drive system.
Methods: The conventional finite control set model predictive control (FCS-MPC) can be combined with a pulse width modulation (PWM) modulator due to an effective cost function optimization algorithm which is from the idea of dichotomy. In the algorithm, all the voltage vectors in the constrained vector plane are dynamically selected and calculated through iteration. The whole system including control algorithm and mathematical model of PMLSM is built and tested by simulation using MATLAB/Simulink. Besides, the control algorithm is tested in the FPGA controller through FPGA-in-the-Loop test.
Results: With the modern digital processors or control hardware such as digital signal processors (DSPs) or field programmable gate arrays (FPGAs), the algorithm can be easily executed in less than 10-micro second. This is very proper for industrial applications. The proposed control algorithm is implemented on FPGA and tested by FPGA-in-the-Loop method. The proposed control algorithm can improve the performance of drive system greatly.
Conclusion: The proposed CSF-MPC for PMLSM not only keeps the same dynamic transient performance as FCS-MPC but also greatly decreases the torque ripple in steady state. Furthermore, CSF-MPC is also robust to parameter variations. Simulation and FPGA-in-the-Loop results illustrate that CSF-MPC has an attractive performance for PMLSM drives.

New technology for manufacturing inductors of linear induction motors for magnetic-levitation transport
Authors: Solomin Vladimir A. , Solomin Andrei V. , Trubitsina Nadezda A. , Zamchina Larisa L. , Chekhova Anastasia A.
Published: December 2018

Abstract. Background: Significant economic growth in many countries of the world can contribute to an increase in the speed of movement of modern and fundamentally new vehicles. This will increase the turnover of goods during the transportation of goods, revive international trade, increase the comfort of passengers and reduce their travel time.
Aim: The solution of this problem is the development and wide application of high-speed magnetic-levitation transport (HSMLT) with linear traction engines. It is promising to use linear induction motors (LIM) for the HSMLT drive, which can have various design versions. Linear induction motors come with a longitudinal, transverse and longitudinal-transverse closure of the magnetic flux. LIM inductors can be installed on both high-speed transport crews and in the HSMLT track structure, as it was done in the People’s Republic of China, where express trains on magnetic suspension connect Shanghai with the airport and reliably operate for more than 10 years. The main elements of the inductor of a linear induction motor are a magnetic core (ferromagnetic core) a multiphase (usually three-phase) winding. With the development of high-speed magnetic-levitation transport, the issues of improving the manufacturing technology of various HSMLT devices, including the methods for producing inductors of linear induction motors, will become increasingly relevant. Traditionally, LIM inductors are assembled from pre-manufactured individual parts.
Methods: An integral technology for manufacturing inductors of linear induction motors for high-speed magnetic-levitation transport is proposed and considered by the method of spraying materials onto a substrate through replaceable stencils. The new technology eliminates the alternate manufacture of individual assemblies and parts and their subsequent assembly to obtain a finished product. A method for determining the size of stencils for manufacturing one of the inductor variants of a linear induction motor is proposed as an example.
Conclusion: Integral manufacturing technology is promising for the creation of high-speed magnetic-levitation transport.

The Russian Federation is located at the crossroads of the trade routes of the Eurasian continent, where a significant volume of the transport flow of the world’s trade is formed. The transport potential of the territory of Russia, when implemented as an Integral Transit Transport System (ITTS), is comparable to the benefits from the traditional export of hydrocarbons and other raw materials. Analyzing the efficiency of transport systems, the key is the energy approach. The concept of ITTS is considered, based on all known and being developed transport lines, including high-speed vacuum magnetic levitation transport (VMLT). The fundamental problems are discussed being on the way to achieving the maximal speed, energy efficiency and throughput of VMLT. The preliminary findings are presented obtained from experiments on the test model of the VMLT route. It is concluded that there is a need for a deeper study of the properties of magnetic and superconducting materials in extreme high fields, power and speed regimes to search for fundamentally new technical solutions for the creation of VMLT
Descolonização literária na crônica “A cabeça de Salomé”, de Ana Paula Tavares
Authors: Cammarata Vincenzo
Published: December 2018

Resumo: O objetivo deste artigo é refletir sobre o processo de descolonização literária na obra de Ana Paula Tavares através do uso do discurso religioso e do papel da mulher na ancestralidade de matriz banta, fazendo uma análise crítica do discurso da crônica “A cabeça de Salomé” (2004). Pretende-se demonstrar que as referências culturais a certas formas de expressão comunicativas da narrativa oral e das crenças de origem cabinda e quioca conseguem criar uma nova forma de reescrever a identidade angolana, criando uma contramemória que se contrapõe à memória dominante, imposta pelos colonizadores portugueses ao longo da história. Desta forma, a figura bíblica de Salomé toma uma conotação diferente com respeito ao Evangelho, adaptando-se às necessidades narrativas da autora que quer enfatizar o legado banto para subverter as imagens pré-estabelecidas das convenções culturais ocidentais, que têm afetado dramaticamente o país angolano e a sua identidade nacional.Palavras-chave: Ana Paula Tavares; literatura angolana; espiritualismo banto; análise crítica do discurso.Abstract: By carrying out a critical discourse analysis of the chronicle “A cabeça de Salomé” (2004) by Ana Paula Tavares, the purpose of the present article is to reflect on the process of literary decolonisation, occurring through the development of a religious discourse and the emphasis given to the role of women in Bantu ancestry. This paper aims to demonstrate that the cultural references related to certain forms of expression belonging to the oral tradition, as well as the Cabinda and Tshokwe beliefs evoked by the author, create a new way of re-defining the Angolan identity, by developing an anti-memory as opposed to the dominant memory, which had been imposed by the Portuguese colonisers over the centuries. This way, the biblical figure of Salomé assumes a different connotation compared to the one depicted in the Gospel, as a result of the adaptation to the narrative needs of the author, who wants to emphasise the Bantu legacy in order to subvert the pre-established western cultural conventions that have affected dramatically the Angolan country and its national identity.Keywords: Ana Paula Tavares; Angolan Literature; Bantu Spiritualism; Critical Discourse Analysis.
In Poetic Memory of Zumbi’s Palmares and Abdias do Nascimento’s Quilombismo. In Homage to Abdias do Nascimento (1914-2011)
Authors: Duke Dawn
Published: December 2018

Modern urban formations of the Arts (such as the literary published phenomenon known as Cadernos negros) and activism have roots in the Zumbi-Palmares legacy. Quilombismo, created by Abdias do Nascimento, serves to explain this experience. A contemporary philosophy of identity and nationhood, Quilombismo mirrors Negritude, embracing transformations that erode injustice and inequality. It emerged as a product of Nascimento’s commitment to politics, the Black Movement, literature, and theater. He envisioned his art, speeches, essays, and activism as part of the global anti-racist democratization; his writings reveal influences from Pan-Africanism and a deep commitment to Afro-Brazil. The elevation of quilombo from maroonage and black rural communities to the level of philosophy has provided impetus to date, as literature and activism maintain momentum in an era of diversity. Moving beyond fleeing black bodies in search of Palmares, an image frozen in time, this thinker has provoked dynamic perceptions of cultural affirmation, ensuring the survival of values associated with Zumbi’s Palmares.
“Noite de Almirante”: Interracial Love in Machado de Assis’s Nineteenth Century
Authors: Dutra Paulo
Published: December 2018

In the twenty-first century some scholars started revisiting the works of the mulatto Machado de Assis through discussions about his racial identification and posture with regard to race. As a consequence a new range of reading possibilities has been released. The racial identification of the characters, hence, their interpretations, customarily based on an ideal hegemonic white model of society, began to be revised and challenged. Having racial marks attributed to the characters as the starting point while approaching them reveals Machado’s keen eye on the tension involved in the negotiations of spaces in the not always harmonious relations developed in the extremely mixed-race nineteenth-century Brazilian society. This essay resorts to the short story “Noite de almirante,” hitherto excluded from this perspective, as a case study to demonstrate the potential of such a reading.

Representatividade e empoderamento nas narrativas de escravidão: da literatura à série televisiva
Authors: Mundim Isabella Santos
Published: December 2018

Este trabalho investiga como criadores pertencentes a grupos minoritários traduzem experiências de subjugação e violência em narrativas de representatividade e empoderamento. O foco são duas narrativas de escravidão lançadas em 2016 – o romance The Underground Railroad, de Colson Whitehead, e a série televisiva Underground, de Misha Green e Joe Pokaski – que se propõem o desafio de reelaborar criticamente o passado. Nelas, Whitehead e a dupla Green e Pokaski lembram o que a América esqueceu, retratam a experiência da servidão do ponto de vista de quem a viveu e a experiência do senhor branco do ponto de vista de quem ele escravizou. Nessa perspectiva, The Underground Railroad e Underground superam o mero registro e apontam para acontecimentos e pessoas ausentes dos relatos dominantes. Para além disso, as duas narrativas inauguram espaços e tempos de resistência, já que que assumem o compromisso com a construção da memória dos Estados Unidos a partir do viés da margem e da exclusão.

Aim:to assess the prevalence of bendopnea and association of this symptom with clinical, laboratory and echocardiographic features, clinical outcomes during 2 years of follow­up in ambulatory elderly patients with chronic heart failure (CHF).

Materials and methods.We conducted an open, prospective, non­randomized study of 80 ambulatory patients aged ≥60 years admitted with heart failure II–IV NYHA class CHF. Baseline survey included physical examination, estimation of Charlson comorbidity index, echocardiography and laboratory tests. Bendopnea was considered when shortness of breath occurred within 30 sec of sitting on a chair and bending forward. Mean follow­up was 26.6±11.0 months.

Results.Bendopnea was present in 38.8 % patients. All these patients complained of shortness of breath during physical exertion and 45.2 % of them had orthopnea.  Bendopnea was associated with the male gender (odds ratio [OR] 11.8, 95 % confidence interval [CI] 4.04–34.8, p<0.001), severity of the clinical status (ШОКС [shocks] scale score)  (OR 1.78, 95 % CI 1.29–2.38, p<0.001), Charlson comorbidity index (OR 1.29, 95 % CI 1.07–1.52, p=0.007), coronary heart disease (OR 26.6, 95 % CI 3.34–21.3, p=0.002), history of myocardial infarction (OR 13.9, 95 % CI 4.2–46.6, p<0.001), left ventricular (LV) aneurysm (OR 13.3, 95 % CI 2.69–65.9, p=0.002), increased indexed LV end­systolic diameter (OR 8.2, 95 % CI 1.9–34.1, p=0.004), left atrial size (OR 4.3, 95 % CI 1,4–12.5, p=0.008), indexed LV end­systolic volume (OR 1.32, 95 % CI 1.07–1.64, p=0.010), pulmonary artery systolic pressure (OR 1.26, 95 % 1.03–1.45, p=0.002), high levels of NT­proBNP (OR 1.0, 95 % CI 1.0–1.002, p=0.055), creatinine (OR 1.04, 95 % CI 1.02–1.07, p=0.001), uric acid (OR 1.006, 95 % CI 1.002–1.011, p=0.004); hospitalizations (OR 7.61, 95 % 2.04–28.4, p=0.003), and patient’s mortality (OR 5.63, 95 % CI 1.94–16.4, p=0.001). Multifactorial analysis confirmed association of bendopnea with severity of clinical status (OR 1.70, 95 % CI 1.04–2.8, p=0.033), increased left atrial size (OR 5.67, 95 % CI 2.75–21.32, p=0.029) and Charlson comorbidity index (OR 1.17, 95 % CI 1.04–2.80, p=0.050). During follow­up 51.6 and 12.2 % of patients died among those with and without bendopnea, respectively (OR 4.22, 95 % CI 1.85–9.9, p<0.001).

Conclusion. Bendopnea is associated with an adverse hemodynamic profile and prognosis, what allows to consider this symptom as a reliable marker of CHF severity.

Published: December 2018

Purpose: to elucidate independent clinical and laboratory predictors of adverse cardiovascular events (ACVE) in patients with acute coronary syndrome (ACS) after percutaneous coronary intervention (PCI) with stenting in early inhospital period.

Materials and methods. We included in this prospective single center study 130 patients with ACS who underwent PCI with stenting. All patients prior to and after PCI received dual antiplatelet therapy with acetylsalicylic acid and clopidogrel. In 12–48 hours after PCI we measured residual platelet reactivity (RPR) using light aggregometry. In 57 patients simultaneously we performed genotyping of CYP2C19*2 polymorphisms. The following ACVE were used as end­points and were registered during inhospital observation (mean duration 9.7±3.2 days): sudden death, stent thrombosis, arterial thrombosis of other localization, recurrent angina, cardiac rhythm disturbances requiring special therapy.

Results. Repetitive ACVE were observed in 32 patients. According to unifactorial regression analysis risk factors of their development were, ADP F­induced RPR (р<0.001), levels of creatinine (р<0.001), hemoglobin (р<0.001), and glucose (р=0.026), age (р=0.01), iron­deficiency anemia (р=0.01), left ventricular ejection fraction (р=0.004), number of stents (р=0.015). According to results of multifactorial regression analysis independent predictors of ACVE were: ADP­induced RPR >76 % (р=0.003), levels of creatinine >189 µmol / L (р=0.003), and hemoglobin <114 g / L (р=0.004). Significant effect of homozygous carriage of CYP2C19*2 (G681A) (А / А) on development of stent thrombosis was also detected (р=0.028).

Conclusion. ADP­induced RPR, levels of creatinine and hemoglobin were found to be independent predictors of inhospital ACVE after myocardial revascularization with stenting in patients with ACS.

Purpose:to elucidate predictors of development of chronic thromboembolic pulmonary hypertension (CTEPH) after acute pulmonary artery thromboembolism (PTE).

Material and methods. We included in this study 210 patients hospitalized with diagnosis of submassive and massive PTE from 2013 to 2017. In 1 to 3 years after initial hospitalization these patients were invited for control examination. According to results of this examination patients were divided into two groups: with (group 1, n=45) and without (group 2, n=165) signs of CTEPH. Severity of pulmonary artery vascular bed involvement was assessed by multislice computed tomography (MSCT) angiography and lung scintigraphy. For detection of thrombosis in the inferior vena cava system we used ultrasound angioscanning.   Examination also included echocardiography.

Results.In the process of mathematical analysis, the following risk factors for the development of CTEPH embolism were determined: duration of thrombotic history (group 1 – 13.70±2.05 days, group 2– 16.16±1.13 days, p=0.015), localization of venous thrombosis in the lower extremities (the most favorable – shin veins, popliteal, and common femoral veins, unfavorable – superficial femoral vein). The choice of the drug for thrombolytic and anticoagulant therapy: streptokinase and urokinase were significantly more effective than alteplase, rivaroxaban was superior to the combination of unfractionated or low molecular weight heparins with warfarin. Also, risk factors for the development of CTEPH were the initial degree of pulmonary hypertension and tricuspid insufficiency, as well as the positive dynamics of these indicators at the background of thrombolytic or anticoagulant therapy. Of concomitant diseases, significant risk factors for development of CTEPH were grade 3 hypertensive disease, diabetes mellitus, post­infarction cardiosclerosis. On the other hand, age, gender, degree of severity at the time of admission, presence of infarction pneumonia, surgical prevention of recurrent pulmonary embolism, number of pregnancies and deliveries, history of trauma and malignancies, cardiac arrhythmias produced no significant impact on the development of CTEPH.

Antidiabetic role of high density lipoproteins
Authors: Poteryaeva O.N. , Usynin I.F.
Published: December 2018

Disturbance in lipid metabolism can be both a cause and a consequence of the development of diabetes mellitus (DM). One of the most informative indicator of lipid metabolism is the ratio of atherogenic and antiatherogenic fractions of lipoproteins and their protein components. The review summarizes literature data and own results indicating the important role of high-density lipoprotein (HDL) and their main protein component, apolipoprotein A-I (apoA-I), in the pathogenesis of type 2 DM. On the one hand, HDL are involved in the regulation of insulin secretion by b-cells and insulin-independent absorption of glucose. On the other hand, insulin resistance and hyperglycemia lead to a decrease in HDL levels and cause modification of their protein component. In addition, HDL, possessing anti-inflammatory and mitogenic properties, provide anti-diabetic protection through systemic mechanisms. Thus, maintaining a high concentration of HDL and apoA-I in blood plasma and preventing their modification are important issues in the context of prevention and treatment of diabetes.

Exosomes are extracellular membrane vesicles secreted by cells into biological fluids. The outer membrane of exosomes protects their content from degradation and contains markers of the parent cell. Almost all cells of the body produce exosomes, however, tumor cells secrete them more intensively. Due to fact that exosomes contain proteins of cells secreting them, these vesicles could be a valuable source for biomarkers discovery. Currently, a number of studies prove the participation of exosomes in carcinogenesis. However, there is a problem of isolating pure and characterized exosomes for further use in investigation of functions or identification of tumor protein biomarkers. In this work, we have performed experiments on exosomes isolation from human plasma by three methods: differential ultracentrifugation, ultracentrifugation in sucrose cushion, sedimentation of the exosomal fraction from serum by using a commercial kit. The protein composition of the obtained samples was determined by mass spectrometric methods of selected reactions monitoring (SRM) and shotgun proteomic analysis. The obtained exosomal samples were searched for the presence of exosomal markers (CD9, CD82, HSPA8, CD63). In the samples of exosomes isolated by ultracentrifugation with the sucrose cushion, the content of the above markers was determined as 32.85, 15.59, 6.07 fmol/mg of total protein, correspondently. It was shown that the centrifugation method with the sucrose cushion was optimal for the isolation of exosomes.

Congenital pseudarthrosis of tibia is a genetic, systemic pathology with impaired bone remodeling and unknown pathogenetic mechanisms. Orthopaedic treatment of the disease can fail in some cases. The process of bone remodeling is known to occur under control of local and systemic growth factors, and we sought to explore several osteotropic growth factors, markers of osteogenesis and biologically active molecules in the blood serum of patients with congenital pseudarthrosis of tibia. The study included 12 patients with congenital pseudarthrosis of tibia and anatomical shortening of 2.5±1.1 cm. The' age of patients ranged from 7 years to 18 years. Blood serum was used for enzyme immunoassay analysis. The own blood serum levels of 103 conditionally healthy individuals (of mean age of 13.0±0.27 years) were considered as the norm. Greater changes in the concentration were detected among vascular endothelial and transforming growth factors. The patients showed imbalance in serum TGF, low reparative potential of bone tissue due to osteoclast activation prevailing over differentiation of osteoblasts, progenitor and mesenchymal cells. Dynamics in serum concentration of IGF at the time of frame removal indicated to terminating osteoblast activation and collagen synthesis and concomitant active bone restructuring.

Background: Small bowel pathologies are an enigma for clinicians and difficult to assess and evaluate for clinicians. In order to establish the efficacy of MDCT Enterography in diagnostic characterisation of small bowel lesions, the current study was undertaken.Methods: A prospective observational cross-sectional study was carried out in a tertiary care hospital. 30 patients with clinically suspected small bowel disease underwent CT enterography using iso-osmotic mannitol as neutral enteral contrast. CT enterography diagnoses were compared with clinical, surgical and histopathological results.Results: CT enterography showed a sensitivity (95.83%), specificity (100%), positive predictive value (100%), negative predictive value (85.71%), accuracy (96.66%) in diagnosis of small bowel diseases.Conclusions: CTE is a non-invasive well tolerated and reliable imaging modality for the depiction of small-bowel diseases. It provides excellent visualization of luminal, mural and extraintestinal findings.
