The Use of Vascular Endothelial Growth Factor Inhibitors in Patients with Proliferative Diabetic Retinopathy
Authors: Evgrafov V. Yu. , Kudasheva G. R.
Published: July 2022

Diabetic retinopathy (DR) have been taking a leading position among retinal disorders, causing a persistent and significant decrease in visual functions. The base of the disease is a retinal vascular microangiopathy, which induces a tissue ischemia and excessive production of vascular endothelial growth factors. The main method of treatment for this pathology is a laser photocoagulation. However, it is not always possible to perform appropriate laser photocoagulation, by that limiting its efficacy (cases of hard cataract and hemophthalmos). In addition, this type of treatment might have a number of serious complications, such as macular oedema, recurrent vitreous hemorrhages, the occurrence of fibrosis, atrophic changes in the retina, which leads to a decline in visual acuity and contrast sensitivity, worsening the visual field. Over the past 10 years, vascular endothelial growth factor inhibitors have been introduced into clinical practice, and showed their benefits in the treatment of disorders leading to a pathological angiogenesis. But due to the limited number of systematic observations, assessing the impact of these drugs, is necessary to investigate their efficacy and safety in patients with proliferative DR, in order to develop indications for their use. The purpose of the review is evaluation of the effect of vascular endothelial growth factor inhibitors on active neovascularization in patients with proliferative diabetic retinopathy. There is a literature of international clinical guidelines, randomized clinical trials with a varying level of evidence, articles and publications by groups of authors in the article.

Published: July 2022

The organ of vision is one of the target organs, which is negatively influenced by a number of harmful factors of the working environment and the labor process. Under their influence, the functioning of the visual analyzer can be disrupted, the risk of developing various diseases and injuries increases. The problem of the ophthalmopathology development in persons employed in hazardous industries is relevant, since the protection of the health of the working-age population is of great socio-economic importance. The proposed review of the literature presents the structure and frequency of occurrence of ophthalmopathology in workers of the cement industry, oil refining and petrochemical industries, metallurgical industry, coal and mining industries, manganese ore industry, synthetic rubber production, rubber technical products, synthetic ethyl alcohol, bakery, aviation production, also workers of the underground and railways of the main professions, including those who service underground tunnels. The data of the nosological structure of ophthalmopathology of various hazardous industries workers in Ukraine, India, and some African countries are presented. Among the professionally conditioned pathology of the vision organ, diseases of the anterior part of the eyeball are most common: chronic conjunctivitis, blepharitis, blepharoconjunctivitis, dry eye syndrome. In the general diseases’s structure of the vision organ, the first place is occupied by anomalies of refraction (from 14.3 to 88.9 %). The share of eye injuries ranges from 4 to 12.5 %. The frequency of occurrence of various ophthalmopathologies increases among workers with more than 10–15 years professional experience, which is typical for all industries and industries; there is also a direct connection between diseases of the organ of vision and the class of harmfulness of working conditions.

Orientadores de la decisión de inversión: una conceptualización desde el estilo de liderazgo del emprendedor de impacto
Authors: Contreras-Pacheco Orlando Enrique , Marín-Díaz Julián Camilo
Published: July 2022

En un contexto de búsqueda de oportunidades de inversión, la impresión inicial que sobre un emprendedor se forme un inversionista influye de manera directa en su propio proceso decisional. En ese sentido, el presente trabajo busca estudiar las implicaciones que subyacen a este panorama inicial, puntualmente en un escenario de decisiones de inversión sobre iniciativas que apuestan por el desarrollo sostenible (i.e., inversiones de impacto). Para ello, haciendo uso de un caso de estudio, se despliega un proceso de análisis cualitativo que permite identificar las especificidades del estilo de liderazgo de un emprendedor de impacto determinado, así como la forma en que este mismo estilo podría afectar la eventual decisión de un potencial inversionista. En ese orden de ideas, el presente trabajo contribuye a la transferibilidad y profundización del tópico en cuestión, en diversas áreas del conocimiento.

Authors: Nguyen Hai Thanh , Nguyen Thi Tuyet Mai
Published: July 2022

The capacity of leadership thinking amongst a number of strategic leaders in our country still has certain limitations. The practice of leadership as well as orientations to 2030 and to 2045 with Vietnam being a developed country require leaders at all levels, especially at the strategic level, to develop their leadership thinking. Based on the instructions on leadership thinking according to Lenin's thought, the purpose of this study is to provide some guidelines with regard to training leadership thinking amongst strategic leaders for better performing their assigned roles, tasks, and responsibilities. The study mainly uses qualitative analysis methods with available data sources, from which to synthesize, generalize, then make judgments and propose measures to train leadership thinking. The research findings have shown Lenin's thoughts on leadership thinking, the current situation of leadership thinking of leaders, and on that basis, proposing solutions to train strategic leadership thinking.

Numerical Investigation of a Supersonic Flow in the Near Wake Region of a Cylindrical Afterbody
Authors: Molchanov A.M. , Yanyshev D.S. , Bykov L.V.
Published: July 2022

A computational study of a supersonic flow in the base region and the nearest wake of a cylindrical body moving at a supersonic speed have been carried out. A mathematical model of high-enthalpy flows is presented. In this case, the "prehistory" of the flow was taken into account, i.e., the configuration of the computational domain was as close as possible to the real one. The use of various turbulence models for calculating flow in the base region and the nearest wake was analyzed. The following turbulence models were considered: 1) the Spalart --- Allmaras model; 2) SST model; 3) standard k--ε model; 4) k--ε model with compressibility correction; 5) k--ε RNG (renormalized group) model; 6) k--ε Realizable model; 7) standard Reynolds Stress (RS) model; 8) RS BSL (Reynolds stress baseline) model. Based on a comparison of the calculation results with experimental data, it is shown that: 1) when calculating the flow in the base region and in the wake of the vehicle, it is very important to take into account the "prehistory" of the flow, i.e., to calculate the flow around the entire vehicle; 2) the best match was obtained using Reynolds Stress models and the k--ε RNG model
Identification of the gene coding for seed cotyledon albumin SCA in the pea (Pisum L.) genome
Authors: Mglinets A. V. , Bogdanova V. S. , Kosterin O. E.
Published: July 2022

Albumins SCA and SAA are short, highly hydrophilic proteins accumulated in large quantities in the cotyledons and seed axes, respectively, of a dry pea (Pisum sativum L.) seed. SCA was earlier shown to have two allelic variants differing in mobility in polyacrylamide gel electrophoresis in acid medium. Using them, the corresponding gene SCA was mapped on Linkage Group V. This protein was used as a useful genetic and phylogeographical marker, which still required electrophoretic analysis of the protein while the DNA sequence of the corresponding SCA gene remained unknown. Based on the length, the positive charge under acidic conditions and the number of lysine residues of SCA and SAA albumins, estimated earlier electrophoretically, the data available in public databases were searched for candidates for the SCA gene among coding sequences residing in the region of the pea genome which, taking into account the synteny of the pea and Medicago truncatula genomes, corresponds to the map position of SCA. Then we sequenced them in a number of pea accessions. Concordance of the earlier electrophoretic data and sequence variation indicated the sequence Psat0s797g0160 of the reference pea genome to be the SCA gene. The sequence Psat0s797g0240 could encode a minor related albumin SA-a2, while a candidate gene for albumin SAA is still missing (as well as electrophoretic variation of both latter albumins). DNA amplification using original primers SCA1_3f and SCA1_3r from genomic DNA and restriction by endonuclease HindII made it possible to distinguish the SCA alleles coding for protein products with different charges without sequencing the gene. Thus, the gene encoding the highly hydrophilic albumin SCA accumulated in pea seeds, the alleles of which are useful for classification of pea wild relatives, has now been identified in the pea genome and a convenient CAPS marker has been developed on its basis.
Hereditary predisposition of water voles (Arvicola amphibius L.) to seizures in response to handling
Authors: Nazarova G. G. , Proskurnyak L. P.
Published: July 2022

Finding out the hereditary predisposition to seizures in response to specific external stimuli is important for understanding the causes of epileptiform conditions, developing new methods for their prevention and therapies. In the water vole, individuals with convulsive seizures are found both in natural and laboratory conditions. The data of long-lasting maintenance and breeding of water voles in vivarium conditions were analyzed in order to establish a hereditary predisposition to convulsive seizures, and the influence of sex and age on their development. In the vivarium, seizures are provoked by handling and are observed in 2.4 % of voles caught in the natural population with cyclic fluctuations in abundance. Seizures are observed more often in individuals caught in the phases of decline and depression of abundance than in individuals caught in the phases of rise or peak. Convulsive states are probably an element of adaptive behavior formed in the predator-prey system. In natural conditions, individuals predisposed to convulsive seizures may have a selective advantage when under increasing pressure from predators. Convulsive seizures in response to handling were noted in 29.8 % of descendants of captive-bred water voles. The proportion of such individuals increased significantly if one or both parents had convulsive states, which indicates the presence of a hereditary predisposition to seizures. In parent–offspring pairs, a significant correlation was found between the average age of onset of the first seizures in parents and their offspring, r = 0.42, p < 0.01. The minimum age of registration of seizures in the water vole is 39 days, the maximum is 1105 days, and the median is 274 days. Predisposition to seizures is not related to sex. Genes that control the occurrence of seizures have a pleiotropic effect on life span, since individuals with seizures live longer in vivarium conditions than individuals with a normal phenotype. The water vole can serve as a suitable model object for studying the nature of convulsive states and the evolution of longevity.

Published: July 2022

O turismo tem o potencial de gerar diversos benefícios para o destino turístico. No entanto, quando não há um planejamento adequado norteando o seu desenvolvimento, impactos negativos começam a afetar a atividade. Planejar significa elaborar e organizar o plano para alcançar determinados objetivos previamente definidos. Para tanto, necessita de informações que formem a base para o processo decisório, contribuindo para uma perspectiva a curto, médio e longo prazo. O objetivo geral deste artigo é analisar os documentos oficiais do setor de turismo de uma cidade montanhosa, sendo escolhida a localidade de Campos do Jordão (SP, Brasil), reconhecida como um destino de inverno e de natureza. Pode-se identificar uma ausência sobre a metodologia adotada em cada estudo, além do período considerado para análise, resultando em informações falhas que podem não contribuir com o processo de planejamento do turismo local como se espera.

Life Lessons in Polish Schools: Teachers’ Attitudes Towards Girls and Boys
Authors: Gajda Aleksandra
Published: July 2022

The aim of the study was to analyse teachers’ interactions with students in order to track the differences in the messages given to pupils depending on their gender, and to study the opinions of students about the behaviour of their teachers. As part of the research, 34 hours of lessons (divided into 17 hours of mathematics and 17 hours of Polish language lessons) were observed. Additionally, the opinions of 68 students (34 girls and 34 boys) were analysed. The study employs mixed methods of data analysis (Stromquist 2007), combining a qualitative approach based on elements of grounded theory (Glaser, Strauss 2017) with quantitative comparisons of the frequency of the teacher’s behavior, using χ2 tests. The results indicate the differing nature of teachers’ interactions with girls and boys; the number of interactions and their quality are more favourable in the case of boys. Girls are more often overlooked, and their achievements and contributions are less frequently noticed. In addition, students are aware of the differences in how they are treated by their teachers, pointing out, inter alia, to the importance of providing equal treatment to all students.
Producción Y Purificación De Osteopontina Bovina Recombinante Mediante Escherichia coli Como Fábrica Celular
Authors: Brijaldo Villamizar Angela Patricia , Londoño-Méndez María Camila , Arbeláez Ramírez Luis Fernando , Rueda Fabian
Published: July 2022

Los programas de reproducción y mejoramiento animal requieren la optimización de herramientas biotecnológicas capaces de favorecer los índices reproductivos en diversas especies. El uso de aditivos proteicos que mejoren la criopreservación espermática y la producción de embriones in vitro, parece ser una alternativa interesante. La Osteopontina se ha relacionado con el potencial fecundante del espermatozoide y con el desarrollo embrionario temprano. El objetivo de este trabajo fue determinar las condiciones óptimas para la producción de Osteopontina recombinante (rOPN) mediante el uso de Escherichia coli como fábrica celular. Para esto, el gen de la OPN se insertó en un vector de expresión pET28(a+) inducible por IPTG, con resistencia a la Kanamicina y una cola de histidinas (6xHis-tag). El constructo resultante se usó para transformar células competentes de E. Coli BL21-Star TM. Las colonias transformadas se usaron para la producción de rOPN-H6 a 20, 30 y 37 °C, probándose dos concentraciones del inductor IPTG (1.0 y 0.1mM). Se realizó una purificación de la rOPN-H6 mediante columnas de afinidad con imidazol (10, 50, 200, 350, 500mM). Los resultados evidenciaron que la producción de rOPN-H6 solo fue exitosa a 37°C independiente de la concentración de IPTG empleada. La purificación de la rOPN-H6 fue exitosa usando imidazol a 200mM, con una aparente tendencia a la dimerización luego de obtener la proteína purificada. De este modo, se concluye cuáles son las mejores condiciones para obtener la OPN recombinante, sugiriendo su potencial uso en ensayos de criopreservación espermática y en medios de cultivo para producción de embriones in vitro.
Conceptos clave de la filosofía de Gottlob Frege: Una introducción
Authors: Villamor Iglesias Alejandro
Published: July 2022

El presente artículo tiene como principal objetivo introducir al lector algunos de los conceptos fundamentales de la filosofía de Gottlob Frege. Estos son: el binomio sentido/referencia, el valor veritativo de oraciones con elementos no referenciales, la distinción entre pensar, juzgar y aseverar, su concepción de los indéxicos y los demostrativos, así como su defensa de la existencia de un tercer reino. En algunos de ellos se mostrarán algunas problemáticas asociadas que han sido destacados por pensadores de renombre. Tal es el caso, por ejemplo, de la famosa crítica de Bertrand Russell a la semántica de Frege por su incapacidad para dar cuenta del valor de verdad de oraciones ficticias. Dirigido especialmente al lector lego en la materia, aunque sin perder rigor académico, este trabajo procura presentar algunas de las principales tesis fregeanas a través de sus fuentes primarias.
Esperanza y verdad: Prolegómenos a una filosofía de la esperanza
Authors: Monroy Gutiérrez Einar Iván
Published: July 2022

Aunque una filosofía de la esperanza pareciera ser una propuesta del todo contemporánea (Bloch, Fromm, Husserl, Laín, Marcel, Heidegger, Patočka, Stein), sus esbozos tuvieron lugar en el siglo VI a.n.e. El objetivo principal de esta investigación es exponer los ejercicios preliminares en torno a una filosofía de la esperanza en el marco de la controversia de Heráclito con Pitágoras. Desde un enfoque cualitativo, mediante el método histórico hermenéutico, se hizo un análisis de datos. Como muestra tomamos fuentes primarias sobre los Versos dorados de Pitágoras y los Fragmentos de Heráclito y como secundarias las traducciones y comentarios más reconocidos. El instrumento utilizado fue las fichas de trabajo mixtas. Como resultado, se observa que la esperanza es un problema para el pueblo griego, que en los vv. 52-53 de los Versos dorados y en el fragmento 22B 18 DK se encuentra esbozada como problema filosófico, que este se comprende mejor a partir de la crítica de Heráclito a Pitágoras y en relación con otros fragmentos clave del pensamiento del Efesio. La investigación permite concluir que la esperanza no es un tema exclusivo de la teología ni propiamente contemporáneo, sino inicialmente de la filosofía, que encuentra en el debate de Heráclito con Pitágoras sus formulaciones preliminares y un contexto propicio para problematizarla en su comprensión habitual, repensarla a la luz del espíritu del tiempo y resignificarla como forma-de-vida.
Concepciones psicológicas y resultados prácticos
Authors: Madelrieux Stéphane
Published: July 2022

Es necesario distinguir dos tipos de acercamiento a la relación que hay entre la psicología y el pragmatismo de William James. El primero, ya muy explorado, consiste en mostrar al pragmatismo como un método filosófico y como una teoría del conocimiento que se deriva de una teoría funcionalista de la mente que hace de todas las funciones intelectuales, instrumentos destinados a hacer de la acción algo más inteligente. El segundo acercamiento, raramente notado y que nosotros proponemos analizar aquí, viene a dar lugar a una concepción pragmatista de la psicología en cuanto tal, como disciplina científica. Este proyecto se resume a hacer de la filosofía una “ciencia práctica de la mente”. Mostraremos que debemos entender “práctico” en dos sentidos diferentes pero articulados entre sí. Por un lado, la psicología debe devenir una práctica científica, fundada sobre la investigación de las leyes causales, liberándose de la especulación metafísica (experimentalismo). Por el otro, la constitución de tal ciencia natural es la condición de su aplicación práctica, sobre todo, en la educación y la medicina.
Para la comprensión del pensamiento de James se pueden desprender de tal reformulación de la relación entre psicología y el pragmatismo, tres beneficios. Permite revalorizar toda una serie de textos descuidados que son posteriores a Principles of Psychology (1890) pero anteriores a los escritos sobre el pragmatismo (1898). Autoriza otro tipo de acercamiento entre dos partes de su obra psicológica que raramente se aproximan y parecen heterogéneas. A saber, su concepción biológica de la mente y su compromiso con las “investigaciones psíquicas”. Y, por último, permite complejizar la genealogía de su pragmatismo a menudo señalado como una defensa de la fe religiosa exclusivamente (The Will to Believe, 1896). Ahora lo vemos emerger en los mismos años de su concepción de la psicología como ciencia.
Dialegesthai y autorreflexión: dos perspectivas de la facultad arendtiana de pensamiento
Authors: Sanabria Maria Camila
Published: July 2022

Propongo a los lectores que la facultad arendtiana de pensamiento puede entenderse desde dos perspectivas, como dialegesthai y como autoreflexión, pero que la segunda, mediante el ejercicio de la conciencia narrativa, potencia el carácter preventivo frente al mal. En primer lugar, expongo los tres presupuestos conceptuales de la tesis: la banalidad del mal, el dos-en-uno y la conducta moral. En segundo lugar, presento la facultad arendtiana del pensamiento como una facultad discursiva caracterizada a partir de los símiles de Sócrates y de la interpretación arendtiana de los Diálogos socráticos de Platón. En tercer lugar, presento la facultad de pensar como autoreflexión, caracterizada por la actividad de la conciencia narrativa. Retomando la diferencia de expresión del lenguaje entre dialgeesthai y autoreflexión, concluyo reivindicando la importancia de la narración como actividad de la autoconciencia, y argumento la relación directa de esta actividad narrativa con la conducta moral.
La vida diaria como base del habitar en Heidegger, Nishida y Nishitani
Authors: Maldonado Rebeca
Published: July 2022

Tanto en épocas de pandemia, como en tiempos que denominamos “normales” la vida diaria se revela como base del habitar, bajo la idea de que es la vida diaria lugar constitutivo del mundo y de nosotros mismos, por lo cual, del cultivo y dedicación a la misma, pende la existencia entera. De este modo, si se pensase que no es importante el cultivo de la vida cotidiana, si se pensase que eso no es lo importante y, peor aún, que es algo que hay que dar por supuesto, echaríamos por la borda todo lo que tenemos a la mano para transformarnos a cada instante. Para Heidegger de Ser y tiempo la cotidianidad es el único punto de partida posible para la descripción del Dasein, para mi, no sólo lugar de despliegue metodológico, sino también del habitar mismo. Esta idea hace del Dasein -que somos en cada uno nosotros mismos- posibilidad de creación y despliegue del mundo, y es tan irrenunciable e intransferible como la muerte misma. Para Nishida la vida diaria es alfa y omega del mundo, para Nishitani, el gozne entre nirvana y samsara. En este artículo se abrirá un lugar a Tim Ingold como un pensador del habitar, que repiensa la ocupación heideggeriana como habilidades desarrolladas desde la percepción del ambiente. Insisto mi propuesta de investigación sobre el habitar busca invitar a pensar las raíces de nuestro estar-en sin perder nunca de vista el día a día de la existencia cotidiana.

Published: July 2022

Atmospheric phenomena can influence flight safety through a series of manifestations of the air masses in the flight area. Such a dangerous manifestation is the icing that can seriously affect the performance of aircraft and lead to flight events. The article draws attention to the phenomenon of icing as located on propellers, a phenomenon which is analyzed on both a 2D (aerodynamic profile) and a three-dimensional (three-blade propeller) geometry, using the Qblade freeware tool, and in the case of icing formed on the NACA 0009 leading edge. The aerodynamic analysis proposed for comparison provides graphical and numerical data relevant for an assessment of the degree of influence of icing deposits in the analyzed case, the proposed geometries and the generated numerical data can be exported and exploited later, by using software analysis tools.

Since 1960, after massive investments in the refurbishment of factories and more specifically, of the factories producing military equipment, weapons and ammunition, the evolution of the national defense industry has been constant, Romania managing to produce more than necessary for its own armed forces, the surplus being exported to obtain a substantial contribution to the state budget. The performance of the domestic defense industry was known worldwide, with military products manufactured in the country being purchased by the Warsaw Pact member states, as well as by countries in the Arab world, Asia, Latin America and Africa. In this article we will analyze and highlight the peak period of the Romanian military industry, as well as its export performance, as the sale of military equipment on the international market has contributed substantially to stabilizing the trade balance of the Romanian state and paying off the national debt.

У овом раду анализира се професионални допринос Љубице Марковић (1895–1947), професорке југословенске књижевности и библиотекарке Универзитетске библиотеке у Београду. Припадала је групи првих универзитетски образованих жена запослених у библиотекама Краљевине Срба, Хрвата и Словенаца; у Универзитетској библиотеци је 20 година руководила комплетном обрадом југословенске и остале словенске књиге; била један од оснивача и члан управног одбора Друштва југословенских библиотекара (1931–1939); велики допринос дала је изради прве Библиографије књига женских писаца штампаних у Војводини, Србији, јужној Србији и Црној Гори до свршетка године 1935; веома активна у Удружењу универзитетски образованих жена, посебно се интересовала за развој феминизма код нас.Љубица Марковић до сада није добила заслужено место међу пионирима српског библиотекарства. Штавише, њен допринос развоју професије никада није истраживан нити критички разматран, што је ауторке овог рада мотивисало да направе бар почетни корак у том правцу. Главни извори током истраживања били су документи из Архива Универзитетске библиотеке „Светозар Марковић”, објављена дела саме Љубице Марковић, као и сећања њених колега.
Књига као део фразеологије (на примеру грчког, румунског и српског језика)
Authors: Мутавџић Предраг
Published: July 2022

Уколико пођемо од тога да је књига део општег људског и националног блага, да се савремено друштво не може замислити без ње, будући да и даље функционише као један од најважнијих извора информација, у овом раду се прегледно разматрају фразеологизми формирани путем кључне лексеме књига у савременом грчком, румунском и српском језику. Мада њихов укупан број није велики, то не спречава да их посматрамо као засебну фразеолошку поткласу унутар које се запажају фразеологизми који су, са једне стране, веома блиски, чак сасвим идентични са фразеологизмима који се могу пронаћи у другим европским језицима – што указује на преношење културних утицаја – а са друге стране се запажају и они сасвим идиотипични, својствени само једном језику и, самим тим, непоновљиви. Основни закључак који се намеће јесте да између наведених језика превагу односе структурно подударни фразеологизми, односно фразеолошки степен потпуне еквиваленције, кога прати степен делимичне, док семантичка еквиваленција припада углавном подударном нивоу. Оно не треба да чуди, с обзиром на то да је човеков однос према књизи у неку руку универзалан, мада су јој у сваком балканском друштву приписане и посебне одлике услед неминовних друштвено-културолошких разлика. То значи да су разматрани балкански језици пре хомотипични него идиотипични.

This studi emphasize the importance of the concept of marriage that is tied up in an agreement, in the form of an ijab qobul which is made by a man before Allah witnessed is by the guardian’s parents of the woman he married. This research is based on the increasing number of divorces that occur in people’s  live  due to thw lack of understanding of the true nature of couple’s marriage. Therefore, the author considers that it is necessary to actualize the meaning of marriage which is implied in the bonds of divine commitment ( mitsoqon ghaliza). This study conclude that the marriage of divine commitment (mitsaqon gholiza) contained the interpretation of al-misbah and thabari is not only looking at the biological purpose in a maeeiage but rather the responsibility in a marriage by fulfilling the rights and obligations of each and creating harmonious relationship in order to achieve the saknah mawaddah warohmah family in the househould. So that the agreement can not be played because it will affect human life hereafter.

Mathematical modeling is widely spread among studies dedicated to operational planning on the railway transport. In short-term planning of marshalling station operation heuristic algorithms and simulation modeling are mainly used. It is possible to improve the quality of planning on the basis of models of strict optimization. The authors have created both a mathematical and a computer model of car traffic processing at a marshalling station with the use of mixed integer linear programming. For the realization of the computer model the authors have used a package of applied programs. The paper considers verification of the model. This procedure is necessary for revealing possible technical and content mistakes in a computer realization of a mathematical model. The authors have made the emphasis on revealing content mistakes in marshalling station operation. For the verification of the model the authors have used a logic approach.

Currently, all manufactured cars in Russia must comply with Euro 5 and Euro 6 standards. The requirements for toxicity are constantly being tightened and can be achieved only with the use of special systems, assemblies and mechanisms, in particular, this applies to catalytic converters and oxygen sensors. The loss of their functional properties during operation leads to significant increases in emission standards by an amount of 1.5-15 times, and in some modes, emissions are significantly higher. To significantly reduce the harmful effects of inoperable exhaust systems on the operation of the car engine and the environment, a new diagnostic method based on the control of the run-out time in test modes is proposed. To implement the proposed diagnostic method, a research engine complex, a device for simulating resistance in the exhaust system, a gasoline engine loader and an oscilloscope have been developed and proposed for use. An indicator is accepted as a sensitive diagnostic parameter - this is the engine stop time. Imitation of exhaust tract malfunctions was carried out by forming artificial resistance in it. As a result of the conducted research, the limit values of the resistance and the time parameters of the engine stop time were established. The new method has proven its effectiveness by high reliability of the assessment of the technical condition.

The article discusses a new technology of terminal processing of container traffic, which involves direct transfer of containers by rail mounted gantry cranes between groups of railcars instead of additional shunting procedures for their selection before supplying and withdrawal at loading and unloading railway tracks. In order to implement the accessibility to the gantry crane span, the additional loading and unloading railway track is introduced, intended to discard incoming containers by a gantry crane and their transhipment to the trains marshalling in the specific destination. This technology is applicable in the organization of container trains in regional distribution and storage centers and in the implementation of modal container block-trains with loading and unloading procedures in the same direction. Based on the analysis of technical development of the terminal network, the opportunity of implementing the proposed approach on Russian railways has been provided. The effect of this innovative technology is proposed to be evaluated from the perspective of decreasing the duration of rolling stock handling and, accordingly, reducing the operating costs of a terminal. The simulation of the terminal processing time of a container flow with the traditional and new approaches was carried out on the basis of the Monte Carlo method. On the basis of modeling, the dependence of the magnitude effect size on the number of the containers transhipped is determined.
