Experimental determination of longitudinal forces in front of braking train
Authors: Matvetsov V. I.
Published: January 2020

The number of regularities detected in the experiments described by the author confirms that, despite of the differences in operating conditions between the middle of the 20th century and the present days, the methods of research and assessment of obtained results are still relevant.

Features of the superstructure and track operation at the initial stage of introduction of the welded rails and continuously welded rail strings on the railways of the USSR are examined. It is demonstrated that axial displacement forces are occurred during the train movement, which are one of the most dangerous processes taking place in the track during the rolling stock movement. Axial displacement forces are manifested in the axial displacement of rails on the sleepers or displacement of rails with sleepers on the ballast. Knowledge of axial forces resulted from displacement of one rail line or the entire track is required for competent planning of installation and operation of the jointed rail track and continuously welded rail track, especially in the conditions of the Urals and Siberia. Methods and experimental results are provided for determination of additional axial forces acting in the track at the spike fastening and the individual intermediate fastening in front of braking train at the experimental sections of the continuously welded rail track in severe climatic conditions of the West-Siberian railway, where the annual fluctuations of therail temperature amount to 110°C.

The following conclusions are made based on the analysis of the experiment results and experience of operation of the continuously welded rail strings:

 • no additional axial forces in front of braking train were detected in the continuously welded rail strings of the thermalstressed type without any release of thermal stresses on the independent fixation;

 • experiment confirmed possibility of installation and normal operation of continuously welded rail track on the entire network of railways of the Ministry of Transportation of the USSR;

 • recent wide introduction of trains of 7,100 t, combined trains of 12,600 and 14,200 tons require special attention to parameters of interaction of track and trains.
METHOD FOR MEASURING ENERGY IN HEAT SUPPLY SOURCES
Authors: Bulanin V. A.
Published: January 2020

Objectives. This study was aimed at determining the actual flow rate of a gaseous working fluid by the pressure drop in the constriction device with its changing parameters (speed, pressure, temperature, gas composition).

Method. Since the pycnometric method provides high accuracy in determining the density and is simpler than the calorimetric method for determining the calorific value, the value of the latter can be checked using the dependence proposed in the article. In the event of a discrepancy between the calculated value of the calorific value and the experimentally obtained value of more than 0.5%, the determination of the calorific value and the density should be repeated. The relationship between the density and calorific value of a gas is subject to verification and refinement when gas from other fields is used. In all cases, a sampler should be used to accumulate an average gas sample over an appropriate period of time. The methodological error in calculating the amount of gaseous working fluid can be eliminated or reduced by using a computer as part of an automated heat supply enterprise management system.

Results. It was established that the calorific value of energy fuels non-linearly depends on the hydrogen and carbon contained therein; a formula has been developed to describe this relationship. When studying the energy characteristics of fuels, a previously unknown regularity was established: hydrocarbons ethylene, benzene and annelated hydrocarbons (naphthalene, anthracene, naphthacene, etc.) form the homologous series CnH(n+6)/2  with the homological difference C4H2, while all other series of hydrocarbons have a homological difference CH2.

Conclusion. The greatest difficulties consist in accounting (measuring) the amount of energy contained in the fuel used at TPPs, mainly natural gas, and the coolant, since there are no appropriate technical means for direct measuring the amount of a particular type of energy. The developed theoretical provisions make a certain contribution to the development of the scientific foundations of heat and gas supply, increase accuracy and reduce the complexity of calculating the technical and economic indicators of thermal power plants and boiler houses.

Published: January 2020

Objectives. The study was aimed at improving the reliability of heat supply systems. At present, this is one of the most relevant topics in the field of heat supply. The issue of reliability of heat supply is of great importance in terms of the safety of citizens and the state as a whole. Due to the severity of winter conditions and risk of hypothermia, heat supply security can be considered to be as critical as food security. Therefore, the reliability of heat supply systems becomes one of the most important aspects of the security of the state.

Method. The study was carried out using the method of reservation of the heat supply system by looping.

Result. In order to avoid the defrosting of the heat supply system and reduce additional costs, a redundancy scheme was proposed with one-way connection to the looped main pipelines, additionally looping the pipelines of the heat supply systems between two boiler rooms. The calculation of losses in the event of an emergency in the heating system was carried out.

Conclusion. The most important problem requiring immediate solution is how to increase the reliability and redundancy of the heat supply system itself, in order to achieve minimal discomfort for consumers of heat energy at the time of failure of the source or transmission of the heat supply system. The proposed method for increasing the reliability of operation of heat supply systems is characterized by a high efficiency, since allows the number of idle hours and the total amount of short-received heat to be reduced.

Published: January 2020

Objectives. The article discusses a thermoelectric cooling system (TECS) for ensuring the thermal regime of modular electronic equipment (MEE) located in a cabinet. The main task of the experimental studies is to determine the temperature dependencies of the air-cooled heat-generating elements of a printed circuit board simulator according to TEСS parameters.

Method. In order to conduct experimental studies of a thermoelectric cooling system for printed circuit boards in cassette units using a thermoelectric cooling system, a prototype designed and manufactured in the laboratory was studied on a testing stand.

Result. The directions of constructive solutions for using a TECS device are presented along with a description of the testing stand and procedure. The dependencies of the temperature of the printed circuit board simulator on the heat power taken away by the TECS are considered along with the temperatures of hot and cold junctions, the air flow velocity and the distance between the electronic boards.

Conclusion. The operability of the developed MEE cooling system is confirmed by the experimental studies; the specified cooling method has advantages over conventional forced or natural method and can achieve the temperatures required by the technical operating conditions; when choosing a fan to provide forced circulation of the air flow in the system, it is necessary to take into account the speed of the air flow in the channel; it is necessary to reserve the power of the power supply for the TECS operation in proportion to the power of the heat sources. An important additional point for the functioning of the thermoelectric cooling device is the necessity of ensuring the effective removal of heat from the hot junctions of the thermoelectric module without which it is impossible to use the proposed system.

Published: January 2020

BACKGROUND

YouTube is a popular American video-sharing platform that has been accessible to the public since 2005. Previous studies have shown that YouTube is potentially beneficial to medical education, but the quality of videos still need to be determined.

OBJECTIVE

The goal of this study is to understand the quality of the YouTube videos by evaluating the characteristics of physicians and the total number of views on videos regarding fibromyalgia.

METHODS

The term “fibromyalgia” was searched on the YouTube search engine by relevance, the default setting. Information from the first 100 videos were analyzed. A search was performed on Scopus to determine the h-index and fibromyalgia-related publication for any physician who was featured in the videos.

RESULTS

Of the top 100 videos, there were 64 academic videos, 18 vlogs, 5 interview videos, and 13 miscellaneous videos. Out of the 64 academic videos, 30 physicians, 7 Doctors of Philosophy (Ph.D.), 5 physical therapists, and 5 chiropractors were identified. The majority physicians have an adequate academic affiliation such as h-index and academic publications.

CONCLUSIONS

Residents and medical students will encounter a large number of academic videos on fibromyalgia on YouTube. This study suggests that many videos were posted for academic purposes and that the quality of the videos can be ensured to some degree. However, developing a better systemic evaluation of the quality of YouTube content is still necessary.

Published: January 2020

Objective: The objective of the present work was to prepare an optimized, fast dissolving tablet (FDT) of Pitavastatin to increase its dissolution by applying 32full factorial design.

Methods: Nine formulations (PF1 to PF9) with all possible combinations according to 32full factorial design by selecting two factors i.e. concentration of super disintegrant, Indion414 (5-15%) (A) and sublimating agent, camphor (40-60%) (B) as independent variables at three levels of-1, 0 and 1. The effect of these two variables on three dependent parameters, water absorption ratio (Y1), disintegration time (Y2) and in vitro drug release (Y3) was studied. All the powder blends were evaluated for precompression parameters, and the tablets were prepared by direct compression method which were further evaluated for post-compression parameters. The effect of change in concentration of two selected factors on dependent parameters was studied through 3D surface response plots and polynomial equations using Design expert software version11. Optimized formula was obtained by desirability and overlay plots for which compatibility stability was assessed.

Results: Precompression and post-compression parameters were satisfactorily within acceptable limits. Optimized formulation was prepared to prove the validity of the evolved mathematical model, which contained 6.75 mg of indion414(0.9) and 54 mg of camphor(0.9) with a disintegration time of 21 sec., water absorption ratio of 113 and 93% of drug release within 12 min. The compatibility between drugs and excipients was proved. The dissolution profiles of optimized formulation and commercially available conventional film-coated tablets of Pitavastatin were compared.

Conclusion: The optimized formulation showed significantly (P>0.05) increased drug release compared to commercially available film-coated tablets. No changes in disintegration time, drug content and in in vitro drug release from optimized formulation on storage for 3months at 40 °C±2 °C/75% RH±5% RH were observed during stability studies which confirmed the stability of the optimized formulation.

Published: January 2020

Objective: The study aims for the fabrication, evaluation of drug loading capability and characterization of 3D-nano-cellulose network materials produced by bacteria of fermented aqueous green tea extract in selected culture media.

Methods: 3D-nano-cellulose network (3DNC) materials can be produced by bacteria living in a fermented aqueous green tea extract. 3DNCs include nano-fibers forming networks, which are capable of drug loading to form a prolonged release therapy to improve drug bioavailability. In this study, 3DNC materials are biosynthesized by aerobic bacteria in the standard medium (SM), coconut water (CW) and rice water (RW). 3DNCs were prepared and evaluated for drug carrier using famotidine as a model drug. Famotidine was loaded in 3DNC by the absorption method. 3DNCs were characterized by using FE-SEM and FTIR spectroscopy.

Results: The 3DNCs obtained from CW, and RW have the same characteristics as the 3DNC obtained from the SM, and 3DNCs can be fabricated with the desired thickness and diameter in all three types of culture media. 3DNCs absorbed famotidine in optimum condition without any difference in famotidine loading (28.2 mg) and famotidine entrapment efficiency (90 %). Investigation of the 3DNC structure using FE-SEM has shown that the cellulose fibers of 3DNC-SM and 3DNC-CW have a stable structure without structural change when loading drug under optimal condition.

Conclusion: The results indicate the potential for using 3DNC-SM and 3DNC-CW to design the drug delivery system.

Authors: Andrade Adriana De , Teixeira Ricardo Roberto Plaza
Published: January 2020

Este trabalho investiga os resultados e impactos de atividades de extensão que organizaram sessões de cinedebates realizado no auditório do campus de Caraguatatuba do Instituto Federal de São Paulo (IFSP); desde o ano de 2015. Estes cinedebates são estruturados basicamente em torno da exibição de um filme ou documentário; seguida pela sua posterior discussão. As exibições são gratuitas e abertas para qualquer cidadão da comunidade externa do IFSP. O público, participante, é o mais variado possível: estudantes do próprio IFSP; alunos de outras instituições de ensino do litoral norte de São Paulo; professores de escolas da região; aficionados por cinema; pessoas interessadas pelos temas específicos abordados em cada cinedebates; ex-alunos do IFSP; aposentados etc. O projeto envolve debates com o público presente sobre os vídeos exibidos, na sua contextualização e na reflexão referente às questões científicas, culturais, artísticas, sociais e históricas abordadas. A metodologia utilizada buscou levar em consideração a maior diversidade possível nas produções cinematográficas escolhidas para serem exibidas, de modo a contribuir na formação de cidadãos críticos. Para que um cinedebate funcione, a contento, é necessário o rigor na escolha das obras cinematográficas e um ambiente propício; de liberdade intelectual para que aconteça um debate fraterno de ideias. É preciso também pensar nas prováveis especificidades de cada filme e nas suas consequências durante o debate. Foi possível concluir que trabalhar com filmes e documentários pode ser uma excelente ferramenta para promover reflexões e análises críticas sobre a sociedade e sobre o universo, de forma descontraída e lúdica.

Published: January 2020

O entendimento do sofrimento mental tomou formas diferentes no decorrer da história, ora por caracterizar-se como negativo e místico pelo viés religioso, ora por ser considerado algo que partia da vontade do sujeito. Atualmente, olha-se o sujeito em sofrimento mental não só por seus limites e fragilidades, mas como sujeito saudável, com potencialidades que podem exacerbar a capacidade do indivíduo que não está em sofrimento o tempo todo. Isto posto, compreende-se a necessidade de respeitar as escolhas de vida e a forma com que o sujeito relaciona-se com o meio que ocupa, ao mesmo tempo que pontua-se elementos que contribuem para o bem-estar físico, mental e social. Entendendo a importância do debate sobre o assunto, esse trabalho tem por objetivo apresentar o relato de experiência da atividade de extensão, intitulada: “O sofrimento mental e o cuidado em saúde: variáveis ambientais e as plantas medicinais”, realizada por meio de uma extensão universitária junto ao Movimento das Mulheres Camponesas, que oportunizou um espaço de reflexão sobre o tema. A atividade foi desenvolvida no município de Palmitos/SC, no ano de 2017, durante o IV Encontro Municipal da Alimentação Saudável e oportunizou a troca entre o saber produzido na academia e o saber popular relacionado às plantas medicinais. Nesse encontro, foram ressaltados resultados significativos no que se refere ao campo da saúde mental e a integração do tratamento, agregado ainda ao uso de plantas medicinais.

O programa objetivou promover rodas de EPS – Educação Popular em Saúde –, por meio de reuniões, oficinas, ações educativas, leitura e reflexões de textos que resultaram em discussão, desconstrução, construção, aproximações e encontros com os sujeitos de diversos segmentos sociais, para promover novos saberes e práticas em saúde através do diálogo, criando vínculos de corresponsabilidade na socialização de experiências e atitudes críticas/reflexivas em ações coletivas, para que a saúde seja, de fato, a conquista da luta popular. O mecanismo é utilizado por meio de rodas de discussões, seminários, oficinas e visitas domiciliares. O programa fundamentou-se na promoção de rodas de EPS, como estratégias de diálogo que promovam a saúde na perspectiva da participação social, enquanto promotora da cidadania Nesse sentido, trilhar pelos caminhos da EPS requer atos pedagógicos que permitam que as informações sobre as questões de saúde contribuam para dar visibilidade histórica, social e política, assim como o apoderamento de grupos sociais nas suas necessidades e reivindicações, e permita projetar caminhos prazerosos, educativos e inclusivos de aprender a estar com o outro. Pretende-se, neste relato, descrever a experiência vivenciada com a educação popular, compartilhando a trajetória do grupo e as repercussões entre os participantes e comunidade.
¿Impera la política sobre el derecho? Ciencia política y estado de derecho en la obra de Guillermo O’Donnell
Authors: Sánchez Ortega Jorge Alberto
Published: January 2020

El pensamiento de Guillermo O’Donnell ha sido fundamental para entender los procesos democratizadores y posdemocratizadores en América Latina, pues su enfoque metodológico introdujo conceptos analíticamente pertinentes y heurísticamente fructíferos. El objetivo del presente ensayo es dar cuenta de la importancia en su obra del vínculo metódico entre derecho y ciencia política, a través del análisis de la interrelación disciplinar del concepto estado de derecho junto con otros íntimamente relacionados, como Estado, legalidad, imperio de la ley, ciudadanía, democracia y rendición de cuentas, y de su vigencia en la realidad política actual. A partir de la utilización del método analítico conceptual, se encontró que dicho entrelazamiento permea el conjunto de su obra, lo que le permitió hacer una lectura conceptual innovadora que reivindica la importancia de la ley y el papel activo ejercido por la interacción del binomio orden legal y orden político en procesos democratizadores que no se ajustan a los supuestos del modelo clásico de la ciencia política.

Underpricing is a condition where the stock price in the primary market is lower than the stock price in the secondary market. There are various factors that can affect the level of underpricing of both financial and non-financial factors. This study aims to analyze the effect of underwriter reputation and company age on underpricing.This study uses a sample of companies listed on the Indonesian Sharia Stock Index (ISSI) which conducted an initial public offering in the 2014-2018 period. The sampling technique was conducted using the purposive sampling method with predetermined criteria. Obtained a sample of 88 companies.The results showed that all variables simultaneously had a significant effect on the level of undepricing of shares. Partially the underwriter reputation variable has a significant negative effect on the level of underpricing of shares, while the firm age does not significantly influence the underpricing of shares. The magnitude of the influence of the independent variable research on underpricing shares is 32.4% while the rest is influenced by other variables outside the study

Abstract—Diarrhea becomes the second disease after ARI that causes morbidity and death in Indonesia. Riskesdas in 2007 shows diarrhea as an infectious disease with high morbidity and mortality rates. The morbidity survey by the Directorate General of Disease Control and Environmental Health of the Ministry of Health from 2000 - 2010 showed a tendency for the incidence of diarrheal disease to rise, namely the 2000 Incidence Rate of diarrheal disease 301/1000 population, in 2003 it rose to 374/1000 population, in 2006 it became 423 / 1000 residents and in 2010 became 411/1000 residents. This paper wants to find out the preventive actions taken by the government in controlling diarrheal diseases in terms of environmental sanitation. Literature searches are conducted online and manually on scientific publications in Indonesian or English, with keywords in the form of diarrheal disease, environmental sanitation, public health efforts, government and health offices. The results show that from 25 related publications, 17 publications discuss diarrhea and 8 publications discuss environmental sanitation. The conclusion obtained is the incidence of diarrhea fluctuates from year to year. An increase in diarrheal disease is associated with poor environmental sanitation, the root of which is the lack of awareness and knowledge in particular rural communities to maintain and preserve and carry out healthy living behaviors to break the cycle of diarrheal transmission in Indonesia.

Introduction: Dental injuries could happen anywhere, including in the school compound. Correct management by the teachers in dental emergencies could prevent further damage to the traumatized tooth and improve the success rate of the treatment. Hence, the purpose of this study was to assess the knowledge and attitude towards dental trauma management among the primary school teachers in Kubang Kerian area. Methods: This descriptive study was conducted in three national primary schools in Kubang Kerian and multi-stages sampling was performed to select the subjects. One hundred and twenty teachers (n = 120) were randomly selected and responded to a set of a self-administered questionnaire. The questionnaire consisted of general characteristics, knowledge, and attitude towards dental trauma. Results: A total of 120 primary school teachers, predominantly female teachers (74.2%) participated in this study. More than half of the teachers (62.5%) have more than 15 years of teaching experience. One-third of the teachers (34.2%) have completed first aid training; however, dental trauma management subject was lacking (1.7%). About 31.7% of the respondent had experienced dental trauma case. Eighty-five percent of the teachers did not opt for tooth replantation in the case of avulsion and almost all the teachers (97.5%) did not choose fresh milk as the medium storage of the avulsed tooth. Conclusion: The level of knowledge and attitude on dental trauma management among school teachers is unsatisfactory. As a recommendation, first aid training given to the teachers should include basic knowledge of dental trauma management. The awareness can be improved by organizing talk or campaign on dental trauma management at the school level.Keywords: Children, dental trauma, school teachers.

Introduction: Purpose of this research is to assess the relationship between long-term pediatric liquid medicines (PLMs) consumption and dental caries in 2–12-years-old chronically ill children. Methods: A cross-sectional study was performed in a public pediatric hospital in India for a period of 6 months. A total of 455 children aged 2–12 years old with various chronic diseases who were receiving PLMs for more than 6 months were selected as the subjects in this study and compared with 531 children of similar age group and diseases who received other forms of medication. Dental caries was measured by DMFT/dmft and data collected were analyzed with SPSS (17th version) using statistical tests such as t-test and one-way ANOVA. Univariable logistic regression was used where the significance was fixed at a a p value of less than 0.001. Results: Children on PLMs had an increased risk of dental caries than those on other forms of medications (OR: 3.142, 95% CI: 2.37–4.15, p < 0.001). The prevalence of dental caries was higher (77.8%) in children consuming PLMs when compared to other forms of medication (52.7%). The mean DMFT and dmft scores were significantly higher in the study group when compared to the control group (p = 0.001). Conclusion: Long-term consumption of pediatric liquid medicines containing sucrose as a risk factor for dental caries among chronically ill children. sugar free options has to be used during prescription to prevent medication-triggered caries.Keywords: Paediatric liquid medicine, medication-triggered caries, sugar-free medication
