Authors: Pushkar D Yu , Gvozdev M Yu
Published: January 2019

Material and methods. The study included patients (n=164) in peri- and postmenopause, having a laboratory-confirmed picture of the genitourinary menopausal syndrome - atrophic vulvovaginitis and suffering from recurrent lower urinary tract infections (UTI) - cystitis and urethritis. All patients underwent standard antibacterial therapy (ABT) UTI in accordance with the results of bacteriological urine culture according to Russian clinical guidelines on urology. Against the background of ABT, 164 patients received additional therapy with Trioginal® (the study group - SG) containing estriol, micronized progesterone and Lactobacillus casei rhamnosus Doderleini 35 (LCR 35) lactobacillus strain. Trioginal® was administered intravaginally in two stages: for 20 days, 2 capsules per day, then for 10 days, 1 capsule per day. In the comparison group - CG (n=67) with ABT, Ovipol Klio® (estriol monopreparation) was additionally intravaginally used in two stages: for 14 days, 1 suppository per day, then for 2 weeks, 1 suppository 2 times a week. The control group consisted of 30 patients receiving only standard ABT UTI, local hormone therapy for vulvovaginal atrophy (VVA) was not performed. The observation period was 12 months after the end of the course of therapy. At all stages of treatment, a subjective and objective assessment of the severity of urination disorders and urogenital atrophy (UDI-6 questionnaire), their impact on the quality of life of patients (questionnaire IIQ-7), indicators of bacteriuria, bacterial urine culture and vaginal biocenosis, frequency of undesirable phenomena were carried out.

Espiritualidad y autoconciencia existencial en Tugendhat
Authors: Bonet-Sánchez José V.
Published: January 2019

La filosofía de la religión y la mística del último Tugendhat se inserta en el centro de su etapa antropológica, pero guarda relación con toda su obra precedente. Las raíces antropológicas de la espiritualidad se hallan en la autoconciencia práctica o existencial, que se refiere al conjunto de nuestra vida y está expuesta —more heideggeriano— a la contingencia. A esta responden, según Tugendhat, la religión, con su creencia en seres espirituales (que él rechaza enérgicamente), y diversas formas de místicas orientales impersonales, como el budismo y el tao, que atemperan la voracidad de un yo egocéntrico. El artículo analiza la teorización tugendhatiana de ambos fenómenos y discute su argumento en pro del ateísmo, por mor de la “honestidad intelectual”, lo mismo que su pretensión de tomar las doctrinas místicas únicamente en su vertiente práctico-existencial.
La moral del respeto universal
Authors: Dias Maria Clara
Published: January 2019

En este artículo pretendo presentar la moral del respeto universal y su compromiso con una concepción de justicia igualitaria. Para ello, pretendo aclarar qué significa, de acuerdo con Tugendhat, justificar un concepto de moral, y, más concretamente, aceptar la moral del respeto universal. Para el autor, la pregunta por la aceptación o no de una perspectiva moral está relacionada con la cuestión acerca del tipo de persona que queremos ser, a la construcción de nuestra identidad cualitativa. Con eso, Tugendhat descarta la posibilidad de responder al llamado escepticismo moral y propone la sustitución de la promesa de una fundamentación última de la moral, por la justificación de la mayor plausibilidad de una perspectiva moral, frente a perspectivas morales concurrentes. Promoviendo una relectura del principio moral kantiano como la mejor expresión de nuestra demanda moral, Tugendhat defenderá nuestro compromiso con un concepto de justicia igualitaria y el respeto a los derechos básicos de todos los individuos.
Mística y rebelión

La teoría de Ernst Tugendhat sobre las fuentes de la moral
Authors: Wolf Ursula
Published: January 2019

Para Tugendhat, el principal motivo moral de su enfoque contractualista es el deseo de ser reconocido como miembro de la comunidad contractual. Entre otras cosas, este motivo no puede justificar la prohibición de la crueldad con los animales. Con respecto a este problema, Tugendhat fluctúa entre la adopción de un segundo motivo, la compasión, y la externalización de la actitud hacia los animales y la naturaleza en su conjunto al misticismo. El presente artículo intenta resolver este problema explicando la relación humano-animal y elaborando sus implicaciones éticas. Se argumenta que la moralidad se refiere generalmente a la consideración del bienestar de los seres que son capaces de sufrir. Puesto que el bienestar de estos individuos tiene diferentes dimensiones y nuestras relaciones con ellos también tienen diferentes tipos, de la misma manera la acción moral se basa en diferentes motivos, sin que tengamos que asumir una tensión entre motivos incompatibles.

¿Qué es la filosofía?

Published: January 2019

Pese a todas las dudas acerca de la posibilidad de llegar a un acuerdo en torno a un concepto unitario de filosofía, debo hacer ahora un intento de acotar a qué nos referimos con este término. Inevitablemente, no todos estarán de acuerdo con dicho intento. El criterio debe ser aquí que ese concepto abarque tanto como sea posible de cuanto históricamente ha recibido ese título.  ¿Qué es, pues, la filosofía?

Diálogos cruzados entre Louis I. Kahn, Anne Tyng y Colin Rowe. Centro Comunitario Judío, Trenton
Authors: Martín Domínguez Guiomar , Rodríguez Martín Isabel
Published: January 2019

Los años cincuenta constituyen un punto de inflexión determinante en la carrera de Louis I. Kahn; un momento en el que su ambición por comprender el origen mismo de la arquitectura le llevó a plantear una serie de trasformaciones decisivas en la concepción del orden y el espacio moderno. Sus intuiciones sobre la condición autónoma e indivisible de la estancia desde el íntimo compromiso entre envolvente y estructura se entrelazaron con un interés simultáneo hacia los procesos de crecimiento de la forma, en parte influenciado por figuras clave del contexto norteamericano como Buckminster Fuller o Robert Le Ricolais, pero sobre todo por su intensa colaboración con Anne Tyng. La evolución del proyecto del Centro Comunitario Judío de Trenton puede considerarse un ejemplo paradigmático de esta encrucijada de intereses, al asumir con naturalidad la transición de una trama ‘celular’ de aspecto orgánico a un esquema en tartán de connotaciones clásicas. El principal objetivo de este artículo es arrojar una nueva luz sobre el porqué de dicha transición y para ello propone la reconstrucción del hipotético proceso creativo de su autor, mediante el redibujado de las diferentes versiones del proyecto. Se busca detectar así episodios clave en la toma de decisiones, como el debate establecido entre Kahn y Colin Rowe a raíz de la visita de este último a Filadelfia, que pudo haber fomentado un cambio radical en el modelo anatómico propuesto.
Escalera al cielo de Cai Guo-Qiang, la construcción de un acontecimiento
Authors: Gutiérrez Mora Dolores
Published: January 2019

El presente artículo analiza la obra Escalera al cielo del artista Cai Guo-Qiang, la cual tiene lugar en una pequeña isla de pescadores cerca de la costa sureste de China. Se trata de una obra de arte que se despliega en el ámbito del territorio. La escalera es una estructura efímera, que se construye para ser incendiada, y una construcción simbólica, que pretende conectar la tierra con el cielo, desde lo más general de las aspiraciones humanas. A lo largo del análisis se establecen tres líneas temáticas que recorren la obra y que, a través de su relación con otras referencias tanto teóricas como prácticas, se reconocen como vectores teóricos culturales. Estas son  el extrañamiento producido por el contraste escalar, las nuevas formas de arraigo presentes en la relación de la obra con la comunidad y la temporalidad accidentada que conecta el pasado con el futuro a través del instante. Estos vectores se despliegan en la obra en forma de acontecimiento, arrojando luz sobre la conflictividad territorial contemporánea, y tratando de apuntar hacia modos de actuación que puedan servir como claves en la actuación arquitectónica.

Transformasi Identitas Etnis Melalui Konversi Keyakinan di Masyarakat Pontianak Kalimantan Barat
Authors: Nugraha Muhammad Tisna
Published: January 2019

Tulisan ini bertujuan untuk menjelaskan fenomena rapuhnya konsep identitas etnis dalam masyarakat multikultural. Identitas bukan sebatas menunjuk pada sesuatu yang melekat secara permanen pada individu, tetapi juga pada sesuatu yang terus mengalami perkembangan dan transformasi melalui dasar keyakinan (reiligi). Identitas etnis memang seringkali dikaitkan dengan perbedaan ras, agama, tanah kelahiran, dan latar belakang historis. Perbedaan ini, meskipun demikian, tidak menjadi sesuatu yang dipermasalahkan ketika individu berpindah agama ke Islam. Konversi agama lain ke Islam sebagai konsekuensinya mempengaruhi sejauhmana seseorang diakui sebagai bagian dari etnis tertentu. Studi ini dilakukan pada etnis Dayak, Melayu dan Tionghoa di Pontianak, Kalimantan Barat dengan pengumpulan informasi melalui wawancara, observasi dan dokumentasi. Hasil studi menunjukkan bahwa latar belakang etnis cenderung tidak berperan dalam praktik interaksi sosial yang bersifat multilateral. Dalam konteks ini, kelompok-kelompok etnis beserta anggotanya, justru lebih mudah dipersatukan oleh kesamaan etnis-keagamaan (etno-religius) dibandingkan faktor-faktor lainnya. Disinilah siklus etnisitas telah kembali pada fase klasik dimana pembentukan etnis tidak hanya ditentukan oleh latar belakang historis, wilayah, dan pertalian darah melainkan juga agama.
Kiai Muhaimin and His Outreach Activity of Dakwah for Promoting Moderation and Preventing Conflict: Seeding Pluralism vis-a-vis Preaching Religion
Authors: Sobirin Mohamad
Published: January 2019

Dakwah (English: Preaching) by Kiai (English:  Javanese terminology referring to a Muslim cleric) commonly takes place in mosques, Islamic Boarding Schools, Majlis Taklim, or other Islamic religious forums. The dakwah is practiced mostly by inviting adherents of Islam to be a truly Muslim (Muslim Kaffah), or evoking non-Muslims to convert their religion into Islam for the sake of their salvation in the hereafter. However, a kiai in Yogyakarta who is familiarly called Kiai Muhaimin has practiced a unique style of dakwah. He preaches Islam not only in his in-group communities and habitual places but also in churches and other religious places of worship. His dakwah thus has been reaching a wide range of places of worship of besides Islamic ones. He did not call for non-Muslims to convert to Islam. Rather, he has promoted tolerance and a better understanding of pluralism. Likewise, he aims his religious standpoints on Islam in Muslim communities for seeding actual pluralism among Muslims. He has formulated a conceptual framework of Islamic moderate dakwah as a philosophical basis for building tolerance and coexistence in Indonesian multicultural society and socio-religious life. Through the organization he established, i.e., FPUB (Interfaith Brotherhood Forum), he put into practice such an Islamic moderation.

Difference betwwen the maximum degree and the index of a graph
Authors: Benediktovich V. I.
Published: January 2019

An algebraic parameter of a graph – a difference between its maximum degree and its spectral radius is considered in this paper. It is well known that this graph parameter is always nonnegative and represents some measure of deviation of a graph from its regularity. In the last two decades, many papers have been devoted to the study of this parameter. In particular, its lower bound depending on the graph order and diameter was obtained in 2007 by mathematician S. M. Cioabă. In 2017 when studying the upper and the lower bounds of this parameter, M. R. Oboudi made a conjecture that the lower bound of a given parameter for an arbitrary graph is the difference between a maximum degree and a spectral radius of a chain. This is very similar to the analogous statement for the spectral radius of an arbitrary graph whose lower boundary is also the spectral radius of a chain. In this paper, the above conjecture is confirmed for some graph classes.
Comparative analysis of experimental investigations and numericalsimulation of single-row finned tube bundle at mixed convection
Authors: Marshalova G. S. , Sverchkov S. A.
Published: January 2019

Mixed convective heat transfer is very important for a wide class of engineering tasks. However, the experimental study of mixed convection requires significant implementation costs, high-power equipment, as well as large time costs, so it is proposed to expand the scope of experimental studies using numerical simulation. Numerical simulation of the single-row bundle consisting of bimetallic finned tubes at mixed air convection conditions was performed and experimental data were compared. The formulation of the third-dimensional problem for numerical simulation was realized. The conjugated problem for heat exchange modeling from the tube fins to air was solved. In numerical simulation of air momentum it was taken into account that the Reynolds number based on tube diameter and velocity in the space between fins was varied from 100 to 720. Menter’s k–ω shear stress transport model in standard formulation was used to close the Reynolds equations. Flow visualization on the tube surface revealed the transient nature of the air flow. The temperature distribution visualization in the bundle and the exhaust mine made it possible to see the nature of cooling the finned bundle at mixed convection. Results of numerical simulation and experimental investigations are in good agreement and can be used for expansion of the scope of experiments. The experimental data and the numerical simulation results for the single-row bundle consisting of bimetallic finned tubes at mixed air convection are compared in this paper. Flow near tube surfaces was visualized, and the temperature and velocity distributions in a bundle and in the exhaust mine were obtained.
Fermion with three mass parameters: interaction with external fields
Authors: Kisel V. V. , Pletyukhov V. A. , Ovsiyuk E. M. , Voynova Ya. A. , Veko O. V. , Red’kov V. M.
Published: January 2019

In the article, using the Gelfand–Yaglom general approach, a new 20-component wave equation for spin 1/2 fermion that is characterized by three mass parameters is derived. Based on the 20-component wave function three auxiliary bispinors are determined, in the absence of an external field, these bispinors obey three separate Dirac-like equations with different masses M1 , M2 , M3 . In the presence of external electromagnetic fields, the main equation is not split into the separated equations; instead quite definite mixing of three Dirac-like equations arises. The model is extended to the curved space-time background. If the scalar space curvature differs from zero, then additional terms of geometrical interaction occur between three bispinor components. The model for fermion with three mass parameters allows for the restriction to the case of the neutral Majorana particle.
Redshift of radiation of a point-like source moving in the external Kerr field
Authors: Komarov S. O. , Gorbatsievich A. K. , Tarasenko A. N.
Published: January 2019

The method of calculation of redshift of light from a point-like source that moves in the gravitational field of the Kerr black hole as a function of time of observation is developed. The widely presented in literature methods for solving the boundary problem are based on a numerical selection of parameters of geodesics. In contrast, the proposed method is based on approximate analytical expressions for isotropic geodesics in the Kerr metric. The proposed method is illustrated by the example of a model problem with parameters corresponding to real stars moving in the immediate vicinity of a supermassive black hole located in the Center of our Galaxy. The same example shows the efficiency and good accuracy of this method.
Effect of powerful ultrasound on the combustion processes and phase composition of refractory compounds of titanium at the self-propagating high-temperature synthesis
Authors: Klubovich V. V. , Kulak M. M. , Khina B. B.
Published: January 2019

The effect of ultrasound oscillations (USO) on the heat transfer conditions between a specimen and environment is examined using a specially developed experimental facility. The influence of the USO amplitude on the combustion temperature and velocity as well as on the phase composition and crystal lattice parameters of the synthesized compounds is studied for the self-propagating high-temperature synthesis (SHS) in Ti–С(Si,B) systems. The heat transfer coefficient on the surface of a specimen during its oscillations with an ultrasound frequency is assessed. Possible mechanisms of the effect of USO on the SHS process are considered. It is demonstrated that a decrease in the SHS temperature is connected with cooling the specimen due to forced convection of a surrounding gas, while a change in a phase composition of the synthesized material and the crystallographic parameters of the phases occurs due to changes in the conditions of high-temperature heterogeneous interactions in the SHS wave.
Grain quality in bread wheat lines T. aestivum with introgression of genetic material T. dicoccoides and T. dicoccum
Authors: Orlovskaya O. A. , Vakula S. I. , Khotyleva L. V. , Kilchevsky A. V.
Published: January 2019

Related wild and cultural wheat species are regularly involved for expanding T. aestivum genetic diversity because they contain many valuable genes. We evaluated the effect of the genetic material of tetraploid species of the genus Triticum (T. dicoccoides, T. dicoccum) on the grain quality of introgression lines of spring bread wheat. The composition of the high molecular weight glutenin subunits which play an essential role in the formation of wheat baking properties was identified in the introgression lines of bread wheat and their parental forms. The traits of grain quality (hardness, protein and gluten content, gluten quality) were also evaluated. The lines with Glu-1 loci alleles from wheat relatives T. dicoccoides and Т. dicoccum were selected. It was found that the introgression of alien genetic material into the common wheat genome had a positive effect on the parameters of grain quality such as hardness, protein and gluten content. The lines with Glu-A1 loci alleles from T. dicoccoides and Glu-B1 from T. dicoccum were at the level of a parent wheat variety or of a higher gluten quality. As a result of the research, the new lines of bread soft wheat with high grain quality were found and can be used in the crop breeding.

Structure and mathematical model of gradient jammer cancellers
Authors: Kostromitski S. M. , Shumski A. P. , Davydzenka I. N.
Published: January 2019

In the article, using subsequent transformations of the structure and mathematical model of a classic gradient jammer canceller, the mathematical model and the structure of a gradient jammer canceller with a pre-processor are obtained. A new structure provides that the adaptation speed of a canceller does not depend on the spread of the eigenvalues of the input signal correlation matrix. An intermediate model provides the analysis of weight misadjustment of the classic gradient jammer canceller. The aim of the new mathematical model is a subsequent analysis of weight misadjustment of the jammer canceller with a stable adaptation speed.

Authors: Opanasenko O. N. , Krutko N. P. , Zhigalova O. L. , Luksha O. V. , Kozinets T. A.
Published: January 2019

The adsorption capacity on the interphase surfaces of solution / air and solution / mineral material of binary mixtures of anionic (alkylbenzenesulfonic acid and its sodium salt (ABSCNa)) and nonionic surfactants (Tween-80) was studied. It has been established that the adsorption interaction of binary mixtures of surfactants with the surface of quartz and dolomite is affected by the presence of potential-determining ions that activate the surface of mineral materials, the charge and hydration of the anionic antagonists, the nature of the intermolecular interactions between the surfactant-components of the mixture. It was shown that the ABSCNa / Tween-80 mixture, characterized by low adsorption capacity to the mineral materials under study and absence of interaction between the surfactant components of the mixture, has a maximum oil displacement capacity from the surface of dolomite and quartz.

Authors: Petrova E. G. , Shavshukova Ya. A. , Kotsikau D. A. , Laznev K. V. , Pankov V V.
Published: January 2019

Co0,65Zn0,35Fe2O4nanoparticles were produced by spray-drying in air in presence of NaCl from the solution of nitrates, as well as from the suspension of coprecipitated particles. The precursors obtained were annealed at 300–900 °C in the matrix of the inert component in order to increase the crystallinity degree without substantial increase of the nanoparticle size. Microstructure, morphology and magnetic properties of nanoparticles were studied by XRD, FT-IR spectroscopy, TEM / SEM and magnetometry. For the ferrites obtained from nitrate solutions partial oxidation of Co2+ions to Co3+occurs, which leads to the formation of two spinel phases, ferrite and cobaltite. With the increase of annealing temperature the content of cobaltite decreases and content of ferrite increases. No cobaltite formation was observed for annealing the spray-dried suspension. An increase in the temperature of the heat treatment leads to partial recrystallization of the particles and the ordering of the ferrite crystal structure, which causes an increase in the specific magnetization of the materials: from 32.8 emu/g (before annealing) to 91.3 emu/g (annealing at 900 ° C). The average diameter of nanoparticles after heat treatment does not exceed 100 nm.

Published: January 2019

In the article, trends of lead content in atmospheric air of background territories and cities of Belarus according to NSEM data and their correlation with trends of lead content in the atmospheric air of cities and background territories of Europe and the USA are analyzed. Clear downward trends in lead content in the atmospheric air of the background territories of Belarus are shown: the average annual concentration of lead has decreased over the period from 1990 to 2015 by 77 %. According to EMEP stations measuring data having a continuous series of lead observations in atmospheric air since 1990, the mean annual lead content in atmospheric air at these stations decreased till 2013 on average by 86 %. A downward trend in the lead content was observed in the air of Belarusian cities and of some countries of Europe. The most significant decrease in lead content occurred in the USA, where the average annual maximum 3-month concentration decreased from 1990 to 2016 by 99 %. The relationship between trends in lead levels with trends of anthropogenic emissions is analyzed. Differences between the measured lead concentrations and calculated values by dispersion models are shown, which may be due to the incompleteness of the inventory of lead emissions in a number of countries, as well as the significant contribution of other sources of emission in addition to anthropogenic sources of lead emission into the atmosphere. To identify the reasons for these discrepancies, which may be related to the presence of unrecorded anthropogenic sources, secondary and natural sources, and other factors, additional research is needed.
Solution of the problem of sheet bending by the slip line field method
Authors: Kozhevnikova G. V.
Published: January 2019

One of the limitations imposed on this process of bending is the possibility of cracking on the surface of the sheet during bending. To predict this type of metal destruction, information is needed on the plastic properties of the material and the stress state in the deformation zone during the bending process. The solution of the problem of sheet bending under conditions of a flat-strained state by graphical construction of the slip line field using a rigid cylindrical mandrel has been analyzed. The material model is a perfectly plastic body. The stresses in the deformation zone and accumulated strains have been determined. The bending process is characterized as unidirectional and monotonous. It has been determined that the mean stress on the outer surface of the sheet during bending equals to 1, and it does not depend on the sheet thickness and the radius of the rigid cylindrical mandrel. Verification of the accuracy of the graphical solution is made. The resulting solution can be used as the basis for an experimental method for testing the plastic properties of metals.
Modeling of the technological process of convective drying of lumber
Authors: Sychevskii V. A.
Published: January 2019

A calculation of the technological process of lumber drying in convection drying chamber of periodic action is presented. For this purpose, a three-dimensional geometric model of a drying chamber with a lumber pile is developed. A physico-mathematical model describing the processes of heat and mass transfer both in the drying agent and in the stack is presented. The three-dimensional geometry of the problem was taken into account by using the Ansys Fluent package. The process of mass transfer in wood was described on the basis of User-Defined Function and User-Defined Scalar. The result of calculation of a specific technological regime of drying of stack from pine sawn timber is given, which allowed finding detailed spatial distributions and temporary changes of the temperature and humidity fields for the drying agent and wood. On their basis, graphs of the time variation of the mean values are plotted. The nonlinearity and interrelationship of the processes of heat and mass transfer in a convective drying chamber leads to unsteadiness of the drying process. So, during the warm-up stage, it is not possible to avoid moisture removal from the lumber. At the drying stages, the unsteadiness leads to an oscillatory character of changes of the temperature, the mass fraction of vapour and the relative humidity of air in the gaps between the wood boards at the intensive heat input. Therefore, it is necessary to take additional procedures to keep the drying agent parameters constant at the drying stages. The obtained results can be used for the design of drying chambers and the development of drying regimes of lumber based on the mathematical modeling and computational experiment.
Simulation of m-phase active voltage rectifier with space-vector modulation

Published: January 2019

The autonomous power supply system (APSS) from synchronous magnetoelectric generator and active voltage rectifier (AVR) maximally meets the requirements of the minimum specific mass and the complete coordination of the primary electric power source with the load. With multiphase (m > 3) execution of the electric machine, it is possible to obtain a trapezoidal electromotive force (EMF) and increase the specific power conversion provided that the EMF and the current at the output of the m-phase generator are fully matched. Therefore, the aim of the work is to synthesize the space-vector modulation (SVM) algorithm of the active voltage rectifier to fully match the primary source of electrical energy with the load under the condition of a trapezoidal EMF of the generator. Synthesis of the PVM algorithm for the m-phase AVR is based on the use of a vector-matrix mathematical apparatus. Using the example of a nine-phase system, a SVM algorithm has been developed, the feature of which is the transformation of the generalized voltage vector m-phase coordinate system into (m – 1)/2 voltage vectors with different angular velocities in two-phase orthogonal stationary αβ coordinate systems. At the same time, based on the developed PVM algorithm, it is possible to independently control the (m – 1)/2 voltage vectors in the corresponding αβ planes, providing a signal similar to the EMF of the generator at the input terminals of the AVR. In order to confirm the theoretical propositions, an imitation model of the space-vector modulation unit for the realization of trapezoidal signals at the terminals of a nine-phase AVR has been developed. The efficiency of the developed algorithm is confirmed by the results of simulation modelling. As a result of the evaluation of the energy parameters (operating power) of the phase of power supply system direct current, it is established that the application of the developed space-vector modulation algorithm for the active voltage rectifier in order to fully match the trapezoidal shape of the EMF and the current at the output of the m-phase generator will increase the power of the APSS by 14 % compared to a power supply system of direct current with a sinusoidal form of the EMF and the current of the generator phase. It is established that the developed measuring device can be used to establish the presence of defects like “delamination”. The influence of the depth of the defect placement on the measured parameters is shown.

Published: January 2019

The problems of measurement the physical and mechanical properties of carbon materials by the dynamic microindentation method are considered. The description of the gage design for measurements is given. This gage allows creating different initial energy for straining of the material tested. It is shown that the design of the gage and the device allows testing both integral (in a large volume of straining) values of the hardness and the elastic modulus, and values of these characteristics for different structural components of the carbon-carbon composites materials: carbon rods and pitch. The obtained data confirms the possibility of using the accepted elastoplastic model of straining of the materials tested for the determination of the elastic modulus and hardness. The ratio between the dynamic and static characteristics is derived. Samples from such carbon materials as pyrolitic graphite, silicified graphite, graphite PPG, coal-filled PTFE and polyamide have been certified. Using these samples it was shown that the dynamic indentation method allows determining the elastic modulus in the range from 0.5 to 100 GPa and the hardness of indentation in the range from 20 to 550 MPa with an error not exceeding 10 %. It is established that the developed measuring device can be used to establish the presence of defects like "delamination". The influence of the depth of the defect placement on the measured parameters is shown.

The pathogenesis of chronic pancreatitis and pain syndrome had not been fully studied. The aim of the study was to evaluate the interrelation of fibrotic and ischemic changes in the parenchyma of pancreas, and pancreatic duct pressure in the pathogenesis of chronic pancreatitis. In a prospective study, a morphological, the immunohistochemical study of pancreatic preparations was performed, and the indicators of tissue oximetry and pancreatic duct pressure were studied intraoperatively in 40 patients operated for chronic pancreatitis. It was found that with the progression of fibrotic changes in the pancreatic tissue of patients with chronic pancreatitis, there was an increase in TGF-β1 expression (р < 0.001), an increase in the number of pancreatic stellate cells (r = 0.32, р < 0.05), a decrease in glycogen (ischemia marker). The intraoperative direct measurement revealed a high pancreatic duct pressure: 34.2 (26.6; 45.3) mm Hg, a decrease in oxygenation of the pancreatic tissue that correlate with a degree of fibrosis. The pancreatic tissue in chronic pancreatitis has chronic hypoxia associated with fibrosis and increased pancreatic ductal hypertension. So, secondary pancreatic ischemia can be a significant factor in the progression of fibrosis and chronic pain syndrome in chronic pancreatitis.
Role of stellate cells in the morphogenesis of chronic pancreatitis
Authors: Mozhejko L. A.
Published: January 2019

This review presents an analysis of the literature on the role of pancreatic stellate cells (PSCs) in the pathogenesis of fibrosis, a predominant histological feature of chronic alcoholic pancreatitis. It is shown that ethanol and toxic products of its metabolism can affect PSCs directly and indirectly, facilitating their transformation from a quiescent to an activated state. During the pathological process, PSCs interact with parenchymal and immune cells of the pancreas through cytokines and growth factors. In activated PSCs, the proliferative and migratory activity, as well as the synthesis of extracellular matrix (ECM) proteins increases. A continuous activation of PSCs during the disease promotes the maintenance of inflammation, the deposition of excessive amounts of ECM proteins and the development of pancreatic fibrosis.

Published: January 2019

The article deals with the language accusation tactics in the American political discourse. The author understands accusation as one of the speech methods of the communicative strategy “dealing for a fall” realisation, the purpose of which is to discredit the opponent. Negative metaphors, epithets and nominations, as well as pejoratives, dysphemisms, deictic constructions and rhetorical appeals, are singled out as linguistic accusation techniques. The author comes to the conclusion that the choice of one or another speech technique, in general, depends on the goals set by the communicant, as well as his/her moral and ethical attitudes.
