Published: October 2020

It will be important to forecast future the deterioration of remaining strength on corroded members for working out reasonable maintenance scenarios on steel structure. In this study, the buckling strength analyses, including future forecast, were conducted for the vertical member, which has the combined cross-section in actual aging truss bridge. For constructing the analytical model, a simple corrosion progress model was applied to generating the corroded steel surface. In this corrosion progress model, it assumes that corrosion pits are generated by the attack factors which can be decided by some control parameters for corrosion environment, corrosion form and corrosion area. And, the constant number of the attack factors per year fall all over the discretized steel surface. The corrosion surface in the future can be generated numerically by repeating mentioned above. The average thickness calculated from the numerical corrosion surface was applied to the local corrosion area in each analytical model. From these analytical results, a future forecast method applying a corrosion progress model was discussed by focusing on the aging deterioration of the buckling strength.
APPLICABLE LIMITATIONS ON THE CRIMINAL CODE BASED ON THE 1945 CONSTITUTION, LAW NO. 1 OF 1946 AND THE GOVERNMENT REGULATION NO. 2 OF 1945
Authors: Adhari Ade , Herning SB Tundjung
Published: October 2020

The enactment of Criminal Code (Wetboek van Strafrecht) in Indonesia is based on the 1945 Constitution, Law No. 1 of 1946 and Government Regulation No. 2 of 1945. The existence of these regulations not only gives legitimacy to the implementation of the Criminal Code, but also provides 'boundary signs' in implementing them. This paper aims to examine the limitations of the enactment of the Criminal Code based on various provisions. The limiting signs include: first, the enactment of the Criminal Code is temporary until the Criminal Code is established based on the 1945 Constitution. This means that the Draft Law on the Criminal Code must be ratified immediately. It is a form of carrying out the mandate to renewal of criminal law as stated in the constitution. Second, there is a need to examine the norms of criminal law in the Criminal Code before it is applied (whether the criminal law norms are in accordance with the criteria "does not conflict with the position of the Republic of Indonesia as an independent state or not in conflict with the Constitution"), and third, the application of the articles in the Criminal Code must remain in the Indonesian context.

During operation, parts of the hydraulic hammer are subjected to intense abrasive wear, which leads to a decrease in the duration of their work. The issue of increasing wear resistance occupies a special place in solving the problem of ensuring the necessary resource of these parts. In accordance with the literature data, as well as on the basis of analysis of many years of experience in operating hydraulic hammers, many methods of volumetric and surface hardening of parts are used that do not give a significant effect. Therefore, it became relevant to attract new methods of surface hardening. These methods include ion-plasma chromium plating. As the tasks of the work, a detailed analysis of the damaged working surfaces of the hydraulic hammer parts was provided; the study of changes in the structure and properties of hardened surface areas during operation; development of the hardening process, providing increased wear resistance of parts as a result of ion-plasma chromium plating. We investigated the condition of the working surface of the critical parts of the hydraulic hammer - the hammer and peaks - after hardening and operation. Data were obtained on the nature and intensity of wear in the zones and sections of each part. High-quality chromium coatings were obtained at substrate temperatures not lower than 80–100 ° С. Based on experimental studies, the effect of ion-plasma chromium plating on the wear resistance and mechanical properties of hydraulic hammer parts is proved, and structural changes in the material are analyzed. After operation, the surface of the part may have defects such as scuffing, cracks along the axis of the part, loss of metal mass (decrease in coating thickness), as well as local hardening and deformation of the metal. Ion-plasma chrome plating of parts according to the proposed technology increased their wear resistance by 1.75 times compared with unstressed. The technology of ion-plasma chromium plating ensures the operation of hardened parts without chips and without chipping. In areas of damage to parts, zones of structural transformations characteristic of secondary hardening phenomena are noted.

The article is devoted to the current problem of improving foundry competitiveness. With a continuous increase in load, speed, power, temperature, the influence of aggressive environments, and other factors, an adequate increase in the requirements for the operational properties of parts is observed. Composite casting allows us to obtain high-precision castings following all the requirements that apply to them. Composite casting synthesizes individual elements of a part, which can be performed by the most efficient farming methods for a given element, as well as from optimal materials, depending on the requirements for the parts. The main content of the study is the analysis and detailing of the parameters of an economical technology to produce high-precision composite castings with differentiated physical and mechanical properties of their parts and high operational reliability. Considerable attention is paid to contact processes that communicate between elements. In most cases, these are diffusion interactions determined by defects in the crystalline structure. The contact zone should be homogeneous and controllable in geometric parameters and properties in areas where complex physicochemical processes occur under unsteady thermal conditions. The characteristic features of the production of composite castings are highlighted and described, taking into account the choice of elements for each specific case, with the determination of the parameters that determine the relationship between them on specific examples of the preparation of composite castings. The results of the study confirmed stable performance, reduced costs for the manufacture of castings, metal savings (for example, up to 2 kg per cone). The results indicate a high potential of composite casting as a means of increasing the competitiveness of foundry by manufacturing high-precision castings with an increased operational reliability of cast parts.

Based on the analysis of known researches, it is revealed that the quantity and accumulation rate of cyclic thermal and dynamic loads in the transient modes of normal operation conditions, when violating normal operation conditions and in accident conditions (except for the nuclear reactor vessel) are the key factors of prediction of operation life extension for a heat power equipment (heat exchangers, pumps, armature). The method for predictive estimation of terms of operation life extension of a heat power equipment depending on stress amplitudes in transient and accident conditions, quantity and accumulation rate of cyclic loads, strength metal parameters of a heat power equipment vessels (except for a reactor vessel) is provided. The method is implemented on the example of steam generators of WWERs and using operational data of South-Ukraine-1 (by 2010). Admissible accumulation rate of cyclic loads during operation life extension by 30, 40 and 50 years is a result. The results define insufficient substantiation of nuclear power plant operation in the “maneuverable” modes with a variable reactor power. In this case, the quantity of cyclic equipment loads increases dramatically, and terms of safe operation are limited. The developed method and the obtained results of prediction of operation life extension of heat power equipment can be used for industry programs to extend the operation of Ukrainian nuclear power plants, as well as to improve the regulatory documents governing the conditions and requirements for acceptable safe extension of the operation life of heat power equipment of nuclear and thermal power enterprises. Further improvement of the method proposed in the work for predicting operation life extension of heat power equipment can be based on the development of methods for analyzing the reliability of heat power equipment and databases on operation disturbances.The materials of the presented work are used in the educational process for the training, retraining and advanced training of specialists in the energy industry.

The results of experimental studies of leaching characteristic of liquid radioactive waste of radionuclides from cement matrices for long-term storage are considered. It is shown that leach ability is a characteristic of the chemical resistance of matrices, indicating the ability of the matrix material to prevent the spread of radionuclides localized in them into the environment. It is noted that the rate of leaching of radionuclides from cement matrices changes with the time of their contact with aqueous media. Chronometric dependences of leaching rates are presented and analysed. It is shown that they consist of two sections of different duration. The initial section, lasting up to 250 hours, is distinguished by a higher steepness with a decrease in the absolute value of the speed to 2 orders of magnitude. The subsequent section, lasting up to 2500 hours or more, is characterized by an asymptotic decrease in speed to a constant minimum value. Approximating functions of the experimental chronometric dependences of radionuclide leaching were obtained in the form of power-logarithm expressions, valid in the intervals of the duration of the experiments, with a reliability of at least 0.9. It is shown that monovalent sodium and cesium ions are most intensively subject to leaching. The absolute values of the rates of leaching of monovalent nuclides are two to three orders of magnitude higher than those of divalent ones, all other things being equal. The content of the nuclide in the composition of the compound material has a significant effect on the leaching rate. An increase in matrix temperature promotes an increase in leaching rates, which is most likely due to a positive temperature coefficient of diffusion characteristics. Irradiation of the matrices decreases the leaching rate as a result of a decrease in the porosity of the matrix body and the formation of poorly soluble hydrates. The redox values of matrix-bound solutions have no significant effect on the leaching rate.

The analysis of the known results of RELAP5/V.3.2 simulation for loss of coolant & blackout accidents at WWER nuclear power plants showed that the design accident management strategies with design passive safety systems do not provide the necessary safety conditions for the maximum permissible temperature of fuel claddings, the minimum permissible level of coolant in the reactor and feed water in the steam generators. A conservative thermohydrodynamic model for a design and modernized blackout & loss-of-coolant accident management strategy at a nuclear power plant with WWER has been developed. Design passive safety systems carry out the design accident management strategy: pressurizer safety valves, secondary steam relief valves, and hydraulic reservoirs of the emergency core cooling system of the reactor. Promising afterheat removal passive systems and the reactor level and steam generator water level control systems carry out the modernized blackout & loss-of-coolant accident management strategy. The main conservative assumptions of the presented model of blackout & loss-of-coolant accidents: complete long-term failure of all electric pumps of active safety systems, the temperature of nuclear fuel in the central part of the fuel matrix is assumed as the maximum allowable one, effect of “run down” flow of a turbine feed pump and the coolant level in pressurizer on accident process is not considered. Computational modelling has found that violations of the safety conditions are over the entire range of leak sizes for the design blackout & loss-of-coolant accident management strategy. For the modernized blackout & loss-of-coolant accident management strategy, safety conditions are provided for 72 hours of the accident and more. The presented results of computational modelling of blackout accident management strategies for nuclear power plants can be used to modernize and improve symptom-informed emergency instructions and guidelines for the severe accident management at nuclear power plants with WWER. Application of the results of computational modelling of blackout accident management strategies is generally not substantiated for other types of reactor facilities. In this case, it is necessary to develop calculated models for blackout accident management taking into account the specifics of the structural and technical characteristics and operating conditions for safety related systems of nuclear power plants.

Published: October 2020

A simulation model of the information technology for the technical diagnosis of the impulse heat machine has been developed and studied. The model incorporates such mathematical models as barrel energy; ballistic wave parameters; pressure of powder gases blasting from the barrel face behind the shell and the shot blast and determination of its attenuation rate. The information model enables to obtain parameters of the ballistic wave that accompanies an shot. A simplified mathematical model allows of determining the oblique shock inclination angle to the stream speed depending on Mach number which is represented by the two-dimensional flow wedge. The model of powder gas pressure blasting from the barrel face behind the shell is based on the energy conservation law for the compresses powder gases and makes it possible to avoid solution of the complicated modified Lagrange problem. While the shot blast propagates, at the initial stage it is possible that this blast reaches the record point earlier than the ballistic wave. Such phenomenon can be avoided by selecting a proper angle. The adopted mathematical model determines the shot blast propagation law and allows of evaluating the shot blast speed attenuation. The barrel energy model was based on the solution of the inverse problem of pyrostatics by determining a composition of the combustion gas of the shot. The applied approach provided for use of the model that describes combustion of the fuel and oxidizer mixture. The peculiarity is a necessity to know composition of all components of the arbitrary mixture. The limitation is a necessity that all components are gaseous. The considered case needs to develop a combustion model of a single-component solid substance (nitrocellulose powder) that provides for a possibility to vary the composition of its active part because of its degradation with time.

Blends of coal and biomass burning conditions have been studied; optimal scheme for TPP-210A coal-fired boiler has been recommended; balance calculations in the joint torch that burns anthracite and solid biofuels have been made; according to the chosen design scheme a burner for biomass and coal co-firing for coal-fired boilers TPP-210A have been implemented and preliminary design of the burner has been prepared. The project can be used at any TPP-210A power boiler units, and with minor changes at most boilers that burn anthracite and lean coal. Conclusions. The use of 8-12% of biomass by heat can essentially intensify the processes of anthracite coal. It is recommended to supply biomass pellets from a separate tank via a special mill to the burner where fuel is injected into the pipeline with a conical divider at output. 3D modeling of co-firing has shown a temperature flow and a fuel burn-out growth. A preliminary design of the boiler burner TPP-210A for co-combustion of anthracite and 10% biomass has been made.

Introduction. Diseases of the respiratory system head the list of occupational diseases. They are caused by pollution of the working zone air with harmful aerodispersed particles, use of improper individual respiratory protective devices. Problem Statement. The efficiency of filtering respirators depends on two components: time of protective effect and insulating properties of half-masks. This requires conducting relevant research in order to design the half-masks which allow providing high insulating properties. Purpose. Improvement of protective effect of filtering respirators by improving their design with respect to anthropometric peculiarities of workers’ faces. Materials and Methods. To develop the surface of a half-mask, the equation of free energy of a bent optional plate was used, which is outlined with a two-dimensional spline-surface, its unknown coefficients are defined by the method of proportional parts based on the data of three dimensional coordinates of the key points of anthropometric facial features. Results. Regularities of forming the surface of half-masks were defined based on the data of three dimensional coordinates of the key points of anthropometric facial features. A method was developed for measuring the temperature of obturator surface with a thermal imagery device based on output signal processing, which allows carrying out on-line control of areas where gaps occur along the obturation line as well as defining deterioration of insulating properties of a dust mask and estimating its protection factor. Conclusion. The algorithm of half-mask design was developed with respect to the results of 3D scanning of faces, digital models of head developing as well as half-masks surface and obturator construction associated with them. The reasonable parameters of filtering box, size of ioutlet for providing the minimum pressure difference and regular dust distribution on filtering surface were determined.

O artigo aborda a (in)visibilidade do rural na garantia direito à assistência social, por meio de uma investigação orientada pelo Materialismo Histórico Dialético, que analisou a Constituição Federal de 1988, a Lei Orgânica de Assistência Social (LOAS), de 1993, a Política Nacional de Assistência Social (PNAS) e as Normas de Operação Básica da Assistência Social (NOB-SUAS), aprovadas respectivamente em 2004 e 2012, e entrevistou profissionais e usuários do Sistema Único de Assistência Social. O presente estudo revela que o direito à assistência social para a população rural vem se constituindo de modo insuficiente, uma vez que a precarização da política de assistência social, sob a égide do neoliberalismo, se intensifica no rural,  além da (in)visibilidade do rural, enquanto um fenômeno pluridimensional, uma vez que a classe trabalhadora que vive no rural encontram-se nessa relação contínua entre invisibilidade e visibilidade, em processos dialeticamente simultâneos.
Políticas para pessoa com deficiência e as contribuições de Freire e Montessori
Authors: De Oliveira Silva Jocenir , Fernandes Idilia , Righi Fonseca Luísa
Published: October 2020

A temática central deste artigo versa sobre o atendimento das Pessoas com Deficiência, busca-se deste modo inferir sobre algumas contribuições históricas a partir da pedagogia proposta por Paulo Freire e Maria Montessori. Apesar de em estudos preliminares Freire não ter tratado diretamente sobre o tema pessoa com deficiência, traz em suas obras um vasto material que dividiu barreiras entre a educação para poucos e a sua democratização. Freire (2013, p. 47) defende que a Educação é um processo em que o sujeito deve apreender através da sua vivência, não se evolui recebendo conhecimentos prontos, ou seja: “ensinar não é transferir conhecimentos, mas criar as possibilidades para a sua própria produção ou a sua construção”. Deste modo, permite-se estabelecer uma relação entre a pedagogia de Paulo Freire e a política educacional para as pessoas com deficiência, pois ambas desejam que todas as pessoas da sociedade tenham acesso à política de educação. Já a pedagogia proposta por Maria Montessori está inter-relacionada com a inclusão das pessoas com deficiência, uma vez que seus estudos inicialmente voltaram-se para a educação de crianças com deficiência intelectual.
Criar um Brasil ou ser criado por ele

Ao narrar uma viagem, A Eternidade e o desejo (2008), de Inês Pedrosa, faz-se do discurso intimista e da imersão da protagonista Clara em sua memória pessoal, afetada pela releitura de sermões de António Vieira. Analisaremos o diálogo do texto com elementos formais de romances de ambiente e de narrativas de viagem e como esses formatos são problematizados no romance, ligando-se à discussão sobre o Brasil, território físico, cultural e afetivo “decifrado” pela viagem descrita.
Imigração na literatura
Authors: Grangeia Mario Luis
Published: October 2020

A imigração portuguesa no Brasil foi retratada por autores dos dois países, mas essas representações têm sido pouco estudadas. Neste artigo, aproximações e distanciamentos no imaginário dessa migração são discutidas a partir de livros de três portugueses que viveram em solo brasileiro nos séculos XIX e XX. Cinco imagens da migração – como escravatura, sorte, maturação, desilusão e alma dividida – são vistas e analisadas na prosa de ficção e não ficção de Gomes de Amorim, Ferreira de Castro e Miguel Torga. Tal imaginário é contrastado com o de autores que não imigraram, como Camilo Castelo Branco, Ramalho Ortigão e Eça de Queirós, e com concepções de Eduardo Lourenço e Vitorino Nemésio, que viveram certo período no Brasil e escreveram sobre a presença portuguesa no país.
New record of the Endangered Black-bellied Tern, Sterna acuticauda J.E. Gray 1831, from Tungabhadra River at Siruguppa, Bellary, Karnataka, India

Black-bellied Tern, Sterna acuticauda J.E. Gray, 1831, is an Endangered species currently restricted to a few patches along the major rivers and lakes in the Indian subcontinent. I report it from Tungabhadra River at Siruguppa for the first time. Five individuals in breeding plumage were observed at a 6 km stretch of river, sampled using line transect method. Previous records, with this new locality, suggest that the population of Black-bellied Tern could be fragmented. This new site could be a promising breeding ground for the species; nevertheless, it is under threat owing to uncontrolled sand mining.

ABSTRACT Since drug-resistant nematodes became a common problem in sheep and goat industries, alternative methods using natural products have emerged as a viable and sustainable anthelmintic treatment option. Here, the in vitro effect of essential oil extracted from Lippia gracilis Schauer was assessed on the hatching process of nematodes recovered from naturally infected goats. Essential oil at concentrations of 0.08% (0.008 μL/mL), 0.12% (0.012 μL/mL), and 0.16% (0.016 μL/mL) was able to induce an average inhibition of 74.7, 84 and 93%, respectively. The effective concentration required to inhibit egg hatching in 50% of eggs (EC50) was 0.03452%. Therefore, essential oil of L. gracilis showed promisor in vitro anthelmintic results against egg-hatching of goat gastrointestinal nematodes.

Published: October 2020

ABSTRACT The population of the caterpillar Diatraea saccharalis (Lepidoptera: Crambidae) has increased in the crop of sugarcane in recent years. Although the control of this insect is traditionally carried out through biological control, the use of phytosanitary products has still been necessary. Therefore, the goal of this work was to evaluate the performance of different insecticides in sugarcane borer control, as well as the effect on productivity and total recoverable sugar (TRS). The experiment was conducted in a randomized experimental delineation of blocks, with six treatments and four blocks. Treatments consisted of five insecticides and one control group (without application of insecticide). For calculating the D. saccharalis infestation index, monthly samplings were performed every 30 days, for 12 months. After this period, the final D. saccharalis infestation index was evaluated and calculated for each treatment. In order to compare productivity among procedures, four central lines were collected from each plot. Thus, the samples were weighed for the productivity calculation (TCH) and sent to the laboratory for the total recoverable sugar (TRS) analysis. The chloranthraniliprole (350) insecticide provided a lower index of sugarcane borer infestation, in addition to greater productivity when compared to the other insecticides. There was no significant difference in the parameter of total recoverable sugar (TRS) among treatments.
