The article considers modern sectioning points on contact network and determining the location of the damage, imthe switches, which differs by the introduction of new functions for plemented in the IntTer smart terminal. These new functions are determining a stable (or passing) short circuit in the disconnected deciding whether to perform a quick automatic restart of the circuit breakers after an emergency shutdown or finding the fault zone without testing the insulation of the contact network. The principle of operation of the functions under consideration is analyzed in the article. The limits of the optimum time of the current-free pause of the circuit breaker for automatic re-activation (AR) for each inter-substation zone are established. The paper describes the existing algorithm for automating power supply of an AC traction network (the normal reclosing algorithm) and indicates the unfavorable consequences from its application, in particular, related to the long time of the absence of voltage in the contact network. It was noted that the decision to reduce the voltage recovery time performed by introducing the function of determining the passing (or stable) short-circuit in the switched-off contact network in traction substations is due to the cost of additional high-voltage equipment and requires a rethinking. Thus, a new algorithm for automating the power supply of the traction network (the BAR algorithm) is presented, which is quite easily implemented at the modern sectioning post, which has voltage transformers for each supply line of the contact network, in contrast to the supply lines of the substation contact network and is caused by the transfer of the function of determining the passing (or steady ) short circuit to the sectioning point. In the article, the issue of performing the automatic reclosure of the power line of the traction substation is considered dependent on the successful operation of the BAR algorithm of the sectioning point. It is established that the most rational option is the implementation of a dependent automatic reclosing of a traction substation using telemechanics. The authors analyze the possibility of manufacturing compact sections of the ac contact network on the basis of single-phase re-closers OR-27.5 kV. It is noted that it is advisable to use a new automation scheme in conjunction with the sectionalization points on reclosers.

The article analyzes the heat exchange processes the thermal imaging method using a thermal imaging device. An occurring in the body of an isothermal vehicle when determining algorithm for determining the heat transfer coefficient is proposed, the heat transfer coefficient K by the internal heating method. which makes it possible to calculate its value with an accuracy not The differences are shown in the values of the heat transfer coef-exceeding 5 %, which is regulated by a number of international ficients obtained by the equilibrium internal heating method and normative documents, while reducing the duration of the experiment by at least 6 times. The study gives comparative experimental data and results of calculating the unknown values of K for bodies of isothermal vehicles obtained by the equilibrium method and an express method based on the algorithm described in the article. It is shown that the use of the algorithm for calculating the heat transfer coefficient of the body of an isothermal vehicle will not only increase the productivity of testing stations, but will also lead to the organization of an electronic passport for the thermotechnical state for each body of an isothermal vehicle, the control of which will enable timely diagnosing the thermo-technical condition of the bodies of isothermal vehicles, providing energy-optimal operating modes of energy equipment and, hence, increasing its resource.

Published: October 2018

The possibility of changing bronze in the manufacture of monometallic cast plain bearings with multicomponent aluminum antifriction alloys is considered. Due to alloying of aluminum with tin, lead, copper, zinc, silicon, magnesium and titanium, it was possible to create alloys with increased ability to adapt friction surfaces. According to laboratory tests, the main results of which are given in the article, it is proved that aluminum alloys on a complex of mechanical and tribotechnical properties are close or superior to the investigated bronze BrO4C4S17. Laboratory tests have shown the possibility of manufacturing monometallic plain bearings from experimental cast aluminum alloys, which by mechanical properties are not inferior to the most solid among antifriction bronzes - bronze BrO4C4S17. On a complex of tribotechnical properties, experimental alloys exceed bronze. Due to their high-fusibility, lower density, lower cost and better workability, aluminum alloys have an almost 3-5-fold advantage over economic indicators before tin bronzes. The scope of the proposed alloys will be determined in the course of bench and operational tests. To date, an experimental batch of monometallic bearings of turbochargers TK 33N-02 has been manufactured from the alloy of the AO6S3M4CT series of “Spets Dizel Servis” (Novosibirsk), which successfully passed the bench tests. Bushings 3404.00.112, 3404.00.032 and bearings 3409.00.20, made from an experimental alloy, showed the possibility of replacing the standard bronze BrO8S12 in these turbochargers. It is advisable to carry out operational tests of bearing sleeves from the alloy AO6S3M4CT for turbochargers TK 34, TK 30 and TK 33, as well as bearing inserts for diesel locomotives.
Adaptation of local work organization to modern conditions
Authors: Levin D. Yu.
Published: October 2018

The current state of the organization of local work is characterized by a large number of normative and technological documents that are developed without mutual coordination. Therefore, often the actual situation and the volume of the local work are significantly different from the normative conditions. Disadvantages of the existing organization of local work are: - performance planning of local work based on the achieved performance level of technical tasks cumulative from the beginning of the month without taking into account the real capabilities of stations and freight fronts; - criteria for shunting work does not take into account the use of loading and unloading capabilities of freight fronts; - evaluation of the effectiveness of local work organization does not take into account the final results of freight operations. The end result of local work should be the maximum volume of loading and unloading. The criterion for organizing local work is the optimal working conditions for freight fronts, when, by the time the freight operations are completed, the station has cars for the next timely delivery. The task of operational planning for local work in a mathematical formulation is formulated in terms of the distribution of flows on graphs. The developed algorithm for performing calculations leads to ranging the flow of car arrival to the station to ensure the maximum possible amount of freight work, and also determines the required schedule for its arrival. An operational plan for the transportation of local cars to stations and its supply to freight fronts is being developed as a result of automation of operational planning of local and freight work.

In modern conditions, the important tasks of the Directorate of High-Speed Communication of the JSC “Russian Railways” are to improve the quality of transport services, maintain stable positions in the transport market, and increase demand. The use of a set of marketing tools in “Sapsan” trains allows maintaining price accessibility of transportation and ensures the construction of long-term mutually beneficial relations with customers. Carrying out activities to stimulate demand requires the analysis of a large amount of statistical data for planning, monitoring and summarizing the marketing activities. For information support of the decision-making process on the basis of the ACS “Express-3”, a set of tasks has been developed that provides the calculation of the characteristics of passenger traffic in the segment of high-speed communication. The new functionality allows the user to receive an analysis of the passenger traffic parameters taking into account the demand parameters (age, sex, citizenship) and the conditions of the trip (class of service, availability of benefits, participation in the promotion). In the process of carrying out analytical work, it is important for the specialists of the passenger complex not only to obtain and examine traffic statistics, but also to determine the impact of marketing actions on the amount of revenue receipts. Software implementation of the relationship construction between the volumes of traffic and revenues from the sale of travel documents was carried out on the basis of the ACS “Express-3”. To determine the annual cycles of growth/decline in revenues, it is ensured that an autocorrelation function is constructed and the development trends are determined by the indicator “revenue receipts”. The functionality created on the basis of ACS “Express” is a flexible system of reports that are formed at the user's request, allowing you to view information on the structure of passenger traffic with varying degrees of detail for compiling programs to stimulate demand and analyze its effectiveness.
Modeling of train flow handling through a limiting single-track section of the route at the organization of high-speed operation using the existing infrastructure
Authors: Karasev S. V. , Kalidova A. D.
Published: October 2018

The article examines the problem of studying the process of handling the opposing train flows through a single track section of the route by modeling for the conditions of organizing high-speed operation while minimizing capital investments in infrastructure. The issue of saving capital investments in infrastructure is especially urgent with the small size of high-speed traffic on non-main lines, including feeder lines for high-speed routes. Significant savings can be ensured by using single-track fixed structures, as well as single-track distances in conditions where the construction of the second main track is associated with a significant increase in cost. However, in this case, an important question arises about the effect of high-speed traffic on the capacity of single-track sections and on the line as a whole. When operating a one-track or two-track section of the route, the issue arises on the adequacy of the capacity level of the junction points from two to one track (one-track section of the route, then the limiting element), and also the possible delays of trains. To investigate the conditions for passing trains through such sections of the route, the Barrier-1 program was developed, which makes it possible to estimate the capacity of the limiting element on the basis of the methods of queuing theory. The model implements an algorithm that does not impose any restrictions on the characteristics of the incoming train flow, which makes it possible to investigate the various conditions for trains to pass through the limiting element (in particular, the regularity or irregularity of the flow, the intervals between trains, the occupation times of the limiting element). The results of modeling the passing of counter traffic flows are displayed in numerical form, as well as in the form of the train traffic schedule, taking into account the increase in time on approaches to the limiting element. The model takes into account the peculiarities of passing the opposing train traffic and allows determining optimal way of passing high-speed and other trains through the limiting element of the route. The calculation is provided using the model and analysis of the capacity of a limiting element of the route for various options of the high-speed trains handling organization, as well as the conditions under which the maximum capacity with the minimum number and delay time (decrease) of trains on approaches to the limiting element.

Published: October 2018

On the network of electriﬁed railroads and power lines of advanced countries there is an intensive work undergoing on the conversion of traditional insulating structures made of porcelain and glass to new ones - polymeric. In order to minimize mechanical damage, it is necessary ﬁrst of all to investigate the stress-strain state in the connection zone “end terminal - ﬁberglass rod”, and on the basis of the results obtained, to develop a number of design solutions that make it possible to provide the required reliability of such connection. The analysis of the stress-strain state and the strength of the joint between the ﬁberglass rod and the end terminal is of greatest interest, taking into account the viscoelastic properties of the glue (glue creeping). Authors present a method for calculating axis-symmetric glue joints of polymer insulators based on the ﬁnite element method. The stress state of the junction zone (“end terminal - ﬁberglass rod”) is analyzed. Optimum sizes of the glue-joint connection of the insulator are determined taking into account the viscoelastic properties of the glue. The results of testing the models of polymer insulators of the contact network in the temperature range -60 ... + 100 °C are given and the life of tension (suspension), ﬁxation and console polymer insulators is estimated on the basis of the principle of temperature-time analogy. The proposed technique for assessing the stress-strain state of the glued joint of polymer insulators, taking into account the viscoelastic properties of the adhesive, allows to determine the optimal parameters of the end caps, taking into account the time of action of the load on the insulator. An analysis of the experimental curves of durability has made it possible to establish the norms governing the change in the durability of a polymer insulator, depending on the load acting on it. A load, that provides reliable operation of the polymer insulator for 30 years, can be accepted for tension insulators, which is not more than 40 % of the destructive insulator, and for ﬁxative and console - not more than 45 and 50 % respectively.
Features of the calculation of the plan of forming single-group trains in market conditions
Authors: Hegrey V. Ya. , Shkurin K. M.
Published: October 2018

The article is analyzing the possibility of using an additional parameter for the calculation of the formation of one-group trains, allowing to take into account the costs associated with the motion of rolling stock. A study was carried out at a number of railway sections of the Belarusian Railways aimed at identifying factors that affect the sectional speed of freight trains. The analysis of the obtained results made it possible to conclude that there is a relationship between the train category and its sectional speed. Depending on the traffic intensity and capacity of the site, the difference between the sectional speeds of transit and sectional trains in the investigated areas was from 2 to 18 %. In the development of the train formation plan, it is proposed to apply a new additional parameter for saving costs for cars and locomotives in transit trains Rn . Authors propose formulas for calculating the value of this parameter. The influence of some factors was analyzed including the train composition and mass, the length of the section, the power of the car stream on cost savings when using the proposed parameter in the calculations. The application of the parameter of cost savings in the cars and locomotives in transit trains makes it possible to justify the allocation of separate streams of car traffic for independent purposes, which would be considered economically unprofitable when developing a train formation plan based on calculations performed by traditional methods.
Performance analysis of the working surface of the rails from test batches on the Test Loop of JSC “VNIIZhT”
Authors: Khvostik M. Yu. , Khromov I. V. , Bykova O. A. , Beresten’ G. A.
Published: October 2018

The monitoring of railway rails damage on the railway network of the JSC “Russian Railways” as well as operational and polygon tests are conducted with the purpose of assessing the impact of operating conditions on the intensity of rails damage, obtaining initial data for forecasting rails failures. The increased intensity of rails wear on sites with a complex plan and profile leads to the fact that with a continuous change from the track, rails which have an underutilized service life of more than 20 % are retrieved. Polygon tests on the Test Loop of the JSC “VNIIZhT” near the Scherbinka station can provide the repeatability and reliability of the results, comparative tests are carried out under identical conditions and their duration is several times less than when tested at experimental sites under operational conditions. The results of the polygon tests of new differentially heat-strengthened rails did not reveal any advantages in the wear resistance of special purposed rails (laid in the recommended radius of the curve for its application) when comparing the rails of domestic manufacturers. Metal shelling out on the rolling surface of rails is the main reason for the removal of rails from test batches. The origin and development of defects of this kind is due to both violations of the technology of manufacturing rails, and because of violations of the current maintenance of the track. The metal stock in the area of the rail head of R65 type due to the increase in its dimensions positively affects the extension of the lifetime of the rails, reducing the cost of the life cycle and the rail itself, and the design of the track as a whole. When carrying out a separate study in order to obtain results characterizing the stability of high-quality rails to contact fatigue damage, it is advisable to optimize the conditions of the polygon tests, bringing them closer to operational ones. When forming the test results, it is necessary to expand the list of criteria for assessing the wear resistance of rails, supplementing it with the size of the wear area at the time of a certain operating time of the tonnage, with the introduction of this criterion into the appropriate methods for the polygon (operational) tests.
Influence of equipment rigidity on the natural bending frequency of the EMU train car body
Authors: Guchinsky R. V.
Published: October 2018

The first frequency of the own bending vibrations of the car body of the EMU train is one of the main normalized parameters associated with smooth running. Estimation of this parameter at the design stage allows to accelerate the process of development of design documentation and to reduce further number of tests. Rigidity of the undercarriage and roof equipment of the EMU train cars contributes to the overall rigidity of the body. When simulating the equipment with concentrated masses at the attachment points, underestimating the rigidity of the body results in underestimated values of the first natural frequency of bending vibrations of the body. It is shown that modeling the equipment with a rigid area with subordinate nodes at the attachment points makes it possible to simplify the process of constructing the model and adequately take into account the rigidity of the equipment not only in determining the static characteristics of body deflections, but also in calculating the dynamic characteristic and the first natural frequency. Using subordinate nodes of a rigid area on the surfaces of the fixing holes leads to a reassessment of the natural frequency. Value of the first natural frequency of the body oscillations is linearly dependent on the specific weight of the undercarriage equipment. When designing the bodies of EMU train cars (especially motor cars), in order to increase the frequency value, the equipment boxes should be located, taking into account the compatibility of the deformations of the box frames and the loadbearing structure of the body. Massive boxes for small equipment should be placed as close to the bolster beams as possible. If it is necessary to place largesize boxes under the car equipment, one should consider variants of its location in the central part of the body to include the box frames in the bend of the transverse beams of the frame.
A existência segundo Fernando Pessoa:
Authors: Souza Ricardo Pires de
Published: October 2018

Este trabalho busca demonstrar o paralelo existente entre as ideias junguianas de si-mesmo, de função religiosa e numinoso e a angústia existencial na escrita de Fernando Pessoa. Dentro desse escopo, um aspecto na obra e vida de Pessoa merece olhar analítico: o enfrentamento do vazio existencial - o medo profundo diante da ideia da morte e da completa ausência de significado intrínseco que o mundo natural apresenta, aí incluído, para o poeta, o mundo social humano onde ele se sente eternamente deslocado. Essa é a motivação maior da sua vida e a marca universal da sua obra: a angústia existencial presente em todas as suas personalidades literárias e heterônimos, principalmente o Pessoa "ele-mesmo" ou ortônimo, resultando na Poesia, tida como valor supremo e imagem de Deus. De fato, terror e fascinação caracterizam toda imagem, ideia ou experiência de Deus, fundamento da função religiosa descrita por Jung em sua teoria do inconsciente, fenômeno que ele chama de numinoso. Na teoria junguiana, essa função é psicologicamente representada pelo arquétipo do Self ou si-mesmo, simultaneamente centro e totalidade da experiência psíquica humana, responsável tanto pela geração quanto pela contenção da angústia existencial que nos acomete quando confrontamos nossos dilemas narrativos fundamentais: vida e morte, existência e não-existência, materialidade e imaterialidade, determinismo e indeterminismo, acaso e finalidade. Assim, o fator Self é o responsável por todos os mitos e religiões desde que começamos a sepultar nossos mortos. Individualmente, no fazer imaginativo pessoano, o Self ocupou o lugar do sagrado sob a forma da Poesia.
Polygamy and Muslim Women in Contemporary Indonesian Literature
Authors: Wajiran Wajiran
Published: October 2018

This paper will examine the ways in which polygamy is addressed in contemporary Indonesian literature. The literature that will be analysed is that published after the reformation era, whereby new freedoms have encouraged many Muslim writers to raise this controversial issue. This paper will apply feminist theory especially that of the Muslim feminist Amina Wadud. Furthermore, in order to understand the contextuality of the works, a cultural materialist approach is also applied. There are some Indonesian writers who overtly depict polygamy in their literature, such as Habiburrahman El Shirazy and Alfina Dewi. Although they are all Muslims they have different perspectives in presenting the issue of polygamy in their works. These differences reflect Indonesian Islamic society where polygamy is controversial. Some Muslims accept polygamy as Islamic teaching but others do not.

The article introduces a new approach in linguocognitology based on the semantic analysis of the lexemes, which may become perspective in the studies of the triad: language-personality-national world view. The papers determines the aim—the research of the semantic structure of the lexemes, and the object—common neutral words “litso” and “a face”. The author analyzes semantic, national-cultural and cognitive parametres of these lexemes. The development of derived meanings based on metaphors and metonymy are describes. A set of methods are used: the method of the analysis of the vocabulary definitions, the component analysis, the comparative method and cognitive interpretation of the data obtained. The anticipated results provide an opportunity to understand and explain the world view in multisystem languages. This research has both theoretical and practical value.
CUESTIONES ÉTICAS Y EMOCIONALES ALREDEDOR DEL EGOÍSMO ECONÓMICO
Authors: Calvo Patrici
Published: October 2018

RESUMEN

El autointerés constituye el principal postulado de la teoría económica ortodoxa. Se trata de una perspectiva que ancla sus raíces en el egoísmo psicológico del siglo XVII, que se abre paso en el pensamiento económico a través de los trabajos de autores como Bernard Mandeville y Joseph Butler durante el siglo XVIII, y que encuentra su lugar en la ciencia económica con la revolución marginalista y la posterior emergencia de la escuela neoclásica a lo largo de la segunda mitad del siglo XIX. Sin embargo, la teoría de juegos, en su versión tradicional, evolutiva y neuronal, lleva décadas mostrando una realidad comportamental del agente económico motivacionalmente heterogénea y moralmente comprometida. Por ello, el objetivo del presente estudio será doble. Por un lado, mostrar cómo nace, concreta y desarrolla la perspectiva egoísta para la economía, y, por otro, dilucidar cuál es la perspectiva comportamental que subyace de los últimos estudios neuroeconómicos.

ETHICAL AND EMOTIONAL QUESTIONS ON ECONOMIC EGOISM

ABSTRACT

Self-interest is the main postulate of the orthodox economic theory. It is a perspective that takes root in the psychological egoism of the 17th century, which opens out to economic thought through the works of authors like Bernard Mandeville and Joseph Butler in the 18th century, and which has found its place in economic science with the marginalist revolution and the subsequent appearance of the Neoclassic School in the second half of the 19th century. Nonetheless, in its traditional evolutionary and neuronal version, the Game Theory has spent decades showing a completely different behavioural reality of the economic agent: One that is motivationally heterogeneous and morally compromised. Therefore, the objective of the present study is twofold: on the one hand, to show how the egoistic perspective for economy comes about, is specified and develops; on the other hand, elucidate the behavioural perspective that underlies the latest neuroeconomic studies.
On Rationality in The Traveler’s Dilemma
Authors: Moro Rodrigo , Auday Marcelo , Tohmé Fernando
Published: October 2018

Kaushik Basu presents the Traveler’s Dilemma (TD) as a challenge to Game Theory. This challenge has been experimentally investigated. When faced with Basu’s version of the TD, participants (including experts in game theory) behave inthe way Basu suggests. However, a little change in the game turns out to reverse participants’ choices. The question is, then, whether it is possible to provide an account of the main empirical findings as consequences of rational choices (i.e., torationalize them). There are several proposals in the literature but none of them provides a satisfactory account for why experts in game theory playing against each other usually reject the only undominated option of the TD. The goal of this article is to suggest an alternative proposal that fixes this problem.

Published: October 2018

Moderate epistemic akrasia is the state a subject is in when she believes that p and suspends judgment about whether her evidence supports p. In this article it is argued that, given a certain understanding of the attitude of suspension of judgment, moderate epistemic akrasia is doxastically irrational. The paper starts with a brief introduction that makes explicit some background notions and clarifies the dialectics of the debate. Second, the well-known distinction between propositional and doxastic rationality is introduced and some cases of improper basing are discussed (Turri 2011). Third, two different cases are considered in which one might argue that moderate epistemic akrasia is doxastically rational, and it is argued that none is successful. Fourth, several objections are presented and answered. Finally, some conclusions are drawn.

Граничное поведение и задача аналитического продолжения одного класса рядов Дирихле с мультипликативными коэффициентами как целых функций на комплексную плоскость
Authors: Кузнецов В. Н. , Матвеева О. А.
Published: October 2018

Рассматривается класс рядов Дирихле с мультипликативными коэффициентами, определяющих функции, регулярные в правой полуплоскости комплексной плоскости и допускающие аппроксимацию полиномами Дирихле в критической полосе. Показано, что условие регулярности на мнимой оси позволяет аналитически продолжить такие ряды как целые функции на комплексную плоскость.

В основе доказательсва этого факта лежат свойства аппроцксимационных полиномов Дирихле и идеи Римана-Шварца, заложенные в принципе симметрии аналитического продолжения функций комплексного переменного. Указан класс рядов Дирихле, для которых выполняется условие аналитичности на мнимой оси.

Нужно отметить, что полученный в работе результат имеет непосредственное отношение к решению известной проблемы обобщенных характеров, поставленной Ю. В. Линником и Н. Г. Чудаковым в 1950м году.

Указанный в работе подход в задаче аналитического продолжения рядов Дирихле с числовыми характерами допускает обобщение на ряды Дирихле с характерами числовых полей. Это позвволяет получить аналитическое продолжение не используя функциональное уравнение L-функций Дирихле числовых полей на комплексную плоскость.

Отметим также, что изучаемому в работе классу рядов Дирихле принадлежат и ряды Дирихле, коэффициенты которых определяются неглавными обобщенными характерами. Можно показать, что для этих рядов выполняется условие аналитического продолжения. Еще в 1984 году В. Н. Кузнецов показал, что в случае аналитического продолжения таких рядов целым образом на комплексную плоскость с определенным порядком роста модуля, то будет иметь место гипотеза Н. Г. Чудакова о том, что обобщенный характер является характером Дирихле. Но окончательное решение проблемы обобщенных характеров, поставленной в 1950м году Ю. В. Линником и Н. Г. Чудаковым, будет приведено в следующих работах авторов.
Развитие понятия «артиновость» для алгебр Ли
Authors: Мещерина Е. В.
Published: October 2018

В статье рассматривается развитие понятия "артиновость"для алгебр Ли. Понятие артиновости было введено для ассоциативных колец с условием минимальности. Одновременно с этим оно распространилось на модули и подалгебры. Чуть позже стали рассматривать артиновы йордановы алгебры. Для таких алгебр роль одностороннего идеала играет квадратичный идеал или, как назвал его Н.Джекобсон, вутренний идеал. Артиновость для алгебр Ли через идеалы определяли Ю.А. Бахтурин, С.А. Пихтильков и В.М. Поляков. Они рассматривали специальные артиновы алгебры Ли. С.А. Пихтильков применял артиновы алгебры Ли для построения структурной теории специальных алгебр Ли. Джорджия Бенкарт определила артиновость для алгебр Ли через внутренние идеалы. Ф. Лопес, Е. Гарсия, Г. Лозано исследовали понятие внутреннего идеала применительно к артиновости с помощью йордановых пар. Определение артиновости для алгебр Ли в данной статье представлено в трёх смыслах: через подалгебры, идеалы и внутренние идеалы. Представлена установленная авторами ранее связь между данными определениями. Рассмотрены примеры артиновых алгебр Ли. Описано применение артиновых алгебр Ли к решению проблемы Михалева: первичный радикал артиновой алгебры Ли является разрешимым.
О взвешенном числе точек алгебраической сетки
Authors: Рарова Е. М.
Published: October 2018

Работа посвящена изучению тригонометрических сумм алгебраических сеток с весами, которые играют центральную роль в модификации метода К. К. Фролова, предложенной Н. М. Добровольским в 1984 году. Тригонометрическую сумму алгебраической сетки с весами для вектора ⃗m = ⃗0, естественно, назвать взвешенным числом точек алгебраической сетки.

Во введении данной работы предложено обоснование актуальности темы исследования, даются необходимые определения и факты из современной теории метода К. К. Фролова, доказывается важная теорема о разложении тригонометрической суммы алгебраической сетки с весами в ряд по точкам алгебраической сетки. В разделе «Вспомогательные леммы» приводятся без доказательства необходимые факты из теории весовых функций специального вида, которые играют принципиальную роль в модификации Н. М. Добровольского метода К. К. Фролова.

Используя теорему о разложении тригонометрической суммы алгебраической сетки с весами в ряд по точкам алгебраической сетки и лемму о значении тригонометрического интеграла от весовой функции, в работе выводится асимптотическая формула для взвешенного числа точек алгебраической сетки со специальной весовой функцией порядка 2, которая утверждает, что такое число стремится к единице. Аналогично, показано, что при росте детерминанта алгебраической решётки для любого вектора ⃗m ≠ ⃗0, тригонометрическая сумма алгебраических сеток с весами, заданной специальной весовой функцией, стремится к 0.

Для простоты изложения в основном тексте статьи рассматривается только случай простейшей весовой функции порядка 2.

В заключении сформулированы без доказательства аналогичные утверждения о значениях тригонометрических сумм алгебраических сеток со специальными весовыми функциями порядка r + 1 для произвольного натурального r.

А именно, утверждается, что для взвешенного числа точек алгебраической сетки со специальной весовой функцией порядка r справедливо стремление к 1 с остаточным членом порядка s−1 логарифма детерминанта алгебраической решётки, делённого на r + 1 степень детерминанта алгебраической решётки. Аналогичное утверждение справедливо о стремлении к нулю тригонометрической суммы алгебраической сетки с весами, заданной специальной весовой функцией порядка r + 1.

Authors: Скобельцын С. А.
Published: October 2018

Представлено решение задачи дифракции плоской звуковой волны на упругом эллипсоиде E с внешним слоисто-неоднородным слоем. Эллипсоид находится в полупространстве, заполненном идеальной жидкостью. Граница полупространства Π является акустически жесткой или акустически мягкой поверхностью.

Для решения область, занятая жидкостью, расширена до полного пространства. Введено дополнительное препятствие, являющееся копией E, расположенное зеркально по отношению к плоскости Π. Добавление второй падающей плоской волны обеспечивает выполнение того условия в точках плоскости Π, которое соответствует типу границы полупространства в начальной постановке задачи. Таким образом, задача сводится к задаче о рассеянии двух плоских звуковых волн на двух эллипсоидах в неограниченном пространстве.

Решение проводится на основе линейной теории упругости и модели распространения малых возмущений в идеальной жидкости. Во внешней части окружающей среды решение ищется аналитически в форме разложения по сферическим гармоникам и функциям Бесселя. В шаровой области, включающей два эллипсоида и прилегающий слой жидкости, используется метод конечных элементов (МКЭ).

Представлены результаты расчета диаграмм направленности рассеянного звукового поля в дальней зоне, которые показывают влияние геометрических и материальных параметров эллипсоида на дифракцию звука.

Статья посвящена памяти Олега Николаевича Введенского (1937 – 1981 гг.). О. Н. Введенский был учеником академика И. Р. Шафаревича. Исследования О. Н. и полученные им результаты связаны с двойственностью в эллиптических кривых и с соответствующими когомологиями Галуа над локальными полями, со спариванием Шафаревича-Тэйта и с другими спариваниями, с локальной и квази-локальной теорией полей классов эллиптических кривых, с теорией абелевых многообразий размерности больше 1, с теорией коммутативных формальных групп над локальными полями. Представлены как результаты, полученные О. Н. Введенским, так и новые избранные результаты, развивающие исследования в направлениях фундаментальных групп схем, главных однородных пространств (торсеров) и двойственности. Первая часть статьи, представлення здесь, является введением как в результаты, полученные О. Н. Введенским в направлении двойственности абелевых многообразий и формальных групп, так и в новые избранные результаты, развивающие исследования в направлениях фундаментальных групп схем, главных однородных пространств (торсеров) и двойственности. Во Введении приведены предварительные сведения и представлено содержание статьи. В первом разделе дан краткий обзор избранных результатов по теории алгебраических, квазиалгебраические и проалгебраические группы и групповых схем. Далее, в разделе 2 преставлены избранные результаты по фундаментальным группам алгебраических многообразий, по фундаментальным группам схем, а в разделе 3 - избранные результаты о главных однородных пространствах (торсерах), развивающие исследования О. Н. и других авторов. Термин торсер мы используем как перевод на русский язык в редакции И.Р. Шафаревича английского термина torsor. В разделе 4 даны сведения о двойственности, а в разделе 5 представлены результаты О. Н. по арифметической теории формальных групп и их развитие. Результаты, этого раздела, представленные над локальными и квази-локальными полями K, над их кольцами целых, и над их полями вычетов k, связанны (1) с формальной структурой абелевых многообразий, (2) с коммутативными формальными группами, (3) с соответствующими гомоморфизмами и изогениями. В статье алгебраические многообразия, абелевы схемы и коммутативные формальные групповые схемы определены, как правило, над локальными и квази-локальными полями, над их кольцами целых, и над их полями вычетов. Но кратко рассматриваются эти объектыи и над глобальными полями, так как О. Н. интересовала тематика алгебраических многообразий над глобальными полями и он проводил соответствующие исследования. Предполагается, что характеристика полей вычетов больше 3, если не оговаривается иное.

Я признателен В.Н. Чубарикову за предложение опубликовать статью в сборнике.

Authors: Kam-Magruder Janel , Ackerman Lani , Derthick Annie , Lesage Kirstin
Published: October 2018

Background and Objectives: Caring for geriatrics and palliative care patients requires integrated interprofessional care. Studies regarding interprofessional education in family medicine reveal concerns by residents regarding applicability in future practice. Our study objective was to determine the effectiveness of teaching multispecialty geriatric and palliative care skills to family medicine residents using an interprofessional clinic curriculum.
Methods: We evaluated an interprofessional geriatric and palliative care outpatient curriculum from March 2014 to June 2015. The interprofessional team included pharmacists, psychologists, and family medicine geriatricians and palliative care providers. Family medicine residents in a 3-year residency program completed pre- and postassessments evaluating their confidence and knowledge in specific areas of geriatric and palliative care. These assessments covered their abilities in starting advanced care planning and setting goals in care discussions, as well as fall and depression assessment and elderly medication review. The subsequent resident perception of teaching effectiveness was also assessed. Qualitative comments were evaluated for themes. Patient perceptions were also surveyed.
Results: Family medicine residents completed 52 surveys (51%). Improvements in all areas were significant (P<0.05). Postevaluation mean scores by year and by session demonstrated significant improvements in palliative care tools and teaching effectiveness. Qualitative comments revealed three themes: overall positive or negative educational value and understanding of assessments, reflection on interprofessional collaboration and team experience value, and improvements in logistics and collaboration. Patient satisfaction surveys reported improved satisfaction with their PCMH.
Conclusions: The use of an interprofessional and multispecialty clinic curriculum to teach geriatric and palliative care improved resident self-assessed knowledge and confidence as well as teaching effectiveness. Further studies evaluating resident exposure to such visits could substantiate the long-term influence of this educational endeavor.
Palliative Care Education in the Family Medicine Clerkship:

Published: October 2018

Introduction: Inadequate training of medical students in palliative care has been identified as a barrier to its universal provision. Family medicine physicians frequently provide these services, yet the extent of palliative care training in the family medicine clerkship has been unknown. This study describes the status of palliative care training in the family medicine clerkship, as well as clerkship director perceptions of this training.
Methods: Data were attained through a cross-sectional survey of 141 US and Canadian family medicine clerkship directors administered in fall 2016. Survey items included clerkship director perceived value, interest, and background in palliative care education; presence of educational objectives; hours of training provided; and perceived barriers to palliative care instruction. 
Results: Of the clerkship directors who responded (120/141, 81.5%), 31 (25.8%) reported providing no palliative care education and 75 (62.5%) reported palliative care competencies were not specifically assessed. Background in palliative care and explicit educational objectives were associated with more hours of training in palliative care. Clerkship director training in palliative care correlated with value of teaching it in the clerkship.
Conclusion: Palliative care education in the family medicine clerkship is prevalent but a large portion of clerkships do not offer it, and the majority of clerkship directors do not evaluate this learning. Our study found a positive correlation between clerkship director training in palliative care and value placed on palliative training in the family medicine clerkship. Assessing this training in the family medicine clerkship and pursuing additional clerkship director training in the subject could improve the overall quality of education provided.

O hipnotismo possui aplicações em diferentes especialidades como Psicologia, Odontologia, Cirurgia, Obstetrícia, Oncologia, tratamento da dor crônica, com diferentes finalidades e ótimos resultados. O objetivo desse trabalho foi utilizar a hipnose como complemento para realizar uma exodontia, buscando o controle da ansiedade e da dor. Paciente R.C.A.S., 50 anos, sexo feminino, com indicação de extração da unidade 36, submeteu-se a sete seções de hipnose até poder realizar a extração. Concluído o procedimento, a paciente afirmou não ter sentindo dor. O estudo mostrou que a hipnose pode reduzir satisfatoriamente a ansiedade e a dor em casos de exodontia. Mais estudos são necessários para avaliar o efeito da hipnose em outras cirurgias bucomaxilofaciais.

O câncer (CA) de próstata é o segundo câncer mais comum entre os homens no Brasil e afeta principalmente indivíduos com idade superior a 65 anos de idade. O objetivo do presente trabalho foi determinar as características epidemiológicas de pacientes portadores de câncer de próstata, bem como a prevalência de infecções urinárias nestes pacientes. Pesquisa de caráter descritivo e quantitativo realizada em prontuários, de pacientes adultos atendidos no período de janeiro de 2015 a janeiro de 2016, em um hospital de referência em câncer, situado em Cascavel, Paraná (PR). Foram analisados 503 prontuários de pacientes com idade superior a 30 anos. Destes, 46% possuíam acima de 70 anos, 76% eram de etnia branca, 96% não possuíam ensino superior e 91% realizou tratamento pelo SUS. Infecção urinária foi observada em 29% dos pacientes em tratamento para câncer de próstata sendo que o principal antimicrobiano prescrito foi o Ciprofloxacino (28%). Verificou-se que o número de casos de câncer de próstata vem aumentando gradativamente na população estudada, tornando-se cada vez mais comum em homens principalmente acima de 50 anos, e que a infecção urinária pode estar relacionada com o câncer de próstata devido às alterações celulares e posterior risco de mutação.
A new method for D2O to H2O leak detection and identification of leaky heat exchanger in PHWR by Cerenkov photon counting technique

In pressurized heavy water reactors, leaks from D2O primary coolant and moderator to H2O secondary coolant and other light-water systems in heat exchangers cannot be completely ruled out. High cost of D2O demands that its loss should be prevented to maximum extent possible. Traditionally D2O leak detection and identification of leaky heat exchanger is carried out by measurement of tritium activity in H2O. Since tritium emits low energy beta radiation, its concentration in H2O is measured by mixing it with liquid scintillation solution in a definite proportion in counting vial and counted in a Liquid Scintillation Analyzer. It is very sensitive method for leak detection, but identification of leaky heat exchanger is time consuming and may require low power operation or reactor shut down. In the new method, high energy beta emitting fission products, which emit Cherenkov photons in H2O, were used as the tracer. H2O was poured in 20 mL plastic vials without scintillator and counted on Liquid Scintillation Analyzer. D2O leak was identified by comparing the Cherenkov photon count rate with that of the blank. A discrimination ratio significantly higher than average Cherenkov photon count rate for all heat exchangers was used to identify the leaky one. The technique has advantageous over existing method of D2O leak detection, such as, (1) scintillation chemicals are not required (2) low power operation or reactor shut down is not required for identifying the leaky heat exchanger (3) no generation of radioactive chemical waste (4) on-power leak identification reduces generation of radioactive liquid waste.
