ICU Acquired Weakness in patients with respiratory failure
Authors: Andreichenko Sergei A. , Bychinin Mikhail V. , Korshunov Dmitriy I. , Klypa Tatiana V.
Published: July 2021

Background:Most patients with severe respiratory failure in intensive care unit (ICU) require bed rest. The limitation of physical activity leads to some adverse consequences such as ICU Acquired Weakness (ICUAW). Progression of respiratory failure, including that caused by the new coronavirus infection (COVID-19), can lead to the development of acute respiratory distress syndrome, the treatment of which contributes to a combination of risk factors for the development of ICUAW. Traditional diagnostic methods have certain limitations. Muscle ultrasonography is a modern tool for early detection of muscle mass loss.Aims:To compare different methods of early ICUAW screening and to estimate the incidence and peculiarities of ICUAW in patients with respiratory failure of infectious genesis.Methods:31 patients with severe coronavirus pneumonia (COVID-19+) and 13 patients with viral and/or bacterial lung infection (COVID-19 -) were included in the study. The muscle mass loss percent from day 1 to day 7 was higher in the COVID-19 - group (p=0.022). These patients also had longer durations of the ICU and hospital stay but a significantly lower mortality (2.5 times).Results:The analysis of the parameters of deceased and living patients regardless of the lung damage etiology showed a correlation between the indices of hand grip strength dynamometry (handgrip test) and ultrasonography of the thigh muscles: F1 and D1 (rho=0.6, p=0.003), F1 and S1 (rho=0.6, p=0.005), D1 and F7 (rho=0.9, p=0.001). In addition, the examined levels of the ICUAW markers were associated with age - F1 (rho=-0.6, p=0.001), D1 (rho=-0.4, p=0.003), S1 (rho=-0.4, p=0.004).Conclusions:During the critical illness, ICUAW develops by the 3d day of bed rest in two thirds of patients with respiratory failure of different infectious genesis. The correlation between the investigated markers of ICUAW and age indicates that elderly patients are the most vulnerable category in respect to the formation and progression of muscle weakness in the ICU. The handgrip test can serve as a reliable and simple method of ICUAW screening. Early identification of patients with ICUAW should provide the improvement of nutritional support and individualization of rehabilitation.

Published: July 2021

Background: The coronavirus infection caused by SARS-Cov-2 is characterized by a damage to many organs and systems of the human body. To date, convincing information has been obtained about the involvement of various parts of the nervous system in the pathological process in patients with COVID-19. Among the most frequently described impairments, there are disorders of smell and taste, common disorders of the central nervous system, characterized by general cerebral symptoms, such as headache, asthenization, psychopathological disorders. One of the rare and severe forms of the peripheral nervous system damage in COVID-19 is Guillain-Barre syndrome (GBS), characterized by acute post-infectious inflammatory polyneuropathy with an autoimmune etiology. Clinical case description. We present a clinical case of GBS associated with COVID-19. The disease debuted as a peripheral tetraparesis with a progredient course of up to 21 days. Systemic administration of immunoglobulin stopped the disease progression. The association of GBS with COVID-19 was clarified a month after the disease onset, when bilateral polysegmental pneumonia was diagnosed, and a high level of IgG to the S-protein of SARS-CoV-2 was found, 3 times higher than the level of IgM, which indicated the duration of the disease was not less than three weeks. Conclusion: The GBS development upon infection with SARS-CoV-2 may precede the lung damage. The debut of GBS during the COVID-19 pandemic requires the exclusion of the SARS-CoV-2 etiological role in each case.
On Collections of the Chu Verses (chuci) of the 3rd–10th Centuries
Authors: Kravtsova Marina E.
Published: July 2021

The article deals with factual data on chuci (verses of Chu) collections, presented in the bibliographical treatises from the official historiographic works Suishu (Book of Sui), Jiutangshu (Old Book of Tang) and Xintangshu (New Book of Tang). Although most of the texts there recorded were irretrievably lost, the available information about the genre enables us to assume, firstly, a further growth in the popularity of chuci poetry in the spiritual life of the 3rd6th centuries and among a variety of groups of educated people: from court scholars to literati, who preferred a free-from-service lifestyle, and, secondly, the existence of a series of different versions of the Chuci collections. Thirdly, we may assume the formation of the commentary school of chuci, within which the most important directions of the future studies in the area have emerged.

Published: July 2021

Background: Long distance practice running are growing and nutritional ergogenic are commonly used as a potential aid in final training and competition performance. Caffeine (CAF) and carbohydrates (CHO) are among the most commonly used supplements due to their expected ergogenic properties that can optimize energetic systems. The objective of this study was to examine potential changes in 10-km running performance with acute isolated and combined CAF and CHO supplementation. Material and method: Fifteen recreational endurance-trained runners performed four 10-km running performance on an official athletic track (400 m) under four supplementation conditions: placebo and placebo (PLA+PLA), placebo and caffeine (PLA+CAF), placebo and carbohydrates (PLA+CHO), caffeine and carbohydrates (CAF+CHO). CAF and CHO supplementation consisted of capsules of 6 mg·kg-1 and 8% CHO solution (1 g·kg-1) respectively, ingested 60 and 30 minutes before the performance tests. Placebo was obtained through empty capsules for CAF and juice for CHO without sugar (Clight®). During each trial running speed to calculate 10-km mean velocity (MV) and maximum heart rate (HRmax) were analyzed. Results: There was a difference in the pacing strategy adopted by the runners with higher MV during the initial phase for PLA+CAF and CAF+CHO groups and in the final phase for PLA+ CHO. However, there was no statistically significant difference in 10-km running performance between the conditions, as well as for HRmax. Conclusions: The use of acute, isolated and combined CAF+CHO supplementation had influence in the pacing strategy, but no in 10- km final performance, of recreational runners.

Effect of Attack Angle of Concave and Convex Winglets Vortex Generators on Thermal-Hydraulic Performance of Fin and Tube Heat Exchangers with Field Synergy Principle
Authors: Syaiful  , Yunianto Bambang , Salsabila Carisya Dara , Fajar T.K. Berkah , Soetanto Maria F.
Published: July 2021

In fin and tube heat exchangers, the gas passing through the fin has a lower thermal conductivity than the fluid passing through the tube. The low thermal conductivity brings a high thermal resistance, which suppresses the heat transfer rate. A common practice to enhance fin-side heat transfer is to generate longitudinal vortex by mounting vortex generators (VGs) on the fin. This paper aims to investigate how longitudinal vortex generator (LVG) improves heat transfer and pressure drop. Numerical simulations were carried out to analyze three types of VGs. The installation of VGs was varied with the attack angle changing from 10°, 15°, to 20° with a 1-3-4-7 VG arrangement on the tube. The flow velocity was expressed in Reynolds number (Re) between 364 and 689. The enhancement of heat transfer rate and improvement of pressure drop were analyzed between three types of VG, three different attack angles, and four types of winglet installation, compared to baseline. The simulation results show that the highest convective heat transfer coefficient (84.85%) was achieved by the VG composed of seven concave delta winglet pairs (CDWPs) at the attack angle of 20° and Re = 689; CDWP VG provides the highest heat transfer improvement among all cases.

Authors: Yu Jian , Sui Lili , Xu Yirong , Chi Baoming
Published: July 2021

In recent decades, the network of seismic subsurface fluid observatories is developing constantly, the observation data of subsurface fluids are enriched accordingly, which provides a favorable condition for the research on the formation, occurrence, and development of earthquakes. In the observation data of subsurface fluids, water level and water temperature changes are very important observation indicators, and their fluctuation sequences are quite complicated. Therefore, this paper employed a non-linear cross-correlation method to study the relationship between the water level and water temperature of Huize Well from 2004 to 2006, and found that there’s a significant cross-correlation between the time series of water level and water temperature; then, this study adopted DCCA (detrended cross-correlation analysis) to calculate the cross-correlation coefficient under different scales and explore the continuous changes of water level and water temperature; at last, this paper used the MF-DCCA (Multifractal-DCCA) method to prove that there’s multifractal cross-correlation between the time series of water level and water temperature. Before the M5.1 earthquake in Huize area, there’s an abnormal increase in the width of the multifractal spectrum of the water level and water temperature drawn with a sliding window of 500-hour, and this is a possible earthquake precursor.
Failure Mechanism and Optimization of Throttle Valve Based on Computational Fluid Dynamics
Authors: Yang Ting , Hong Yi , Wang Aijun , Ran Xiaofeng , Fan Xiaojun , Hu Changpeng
Published: July 2021

Throttle valve is an important device in well control manifold. In the process of field use, the valve seat and plug of the valve often have corrosion failure, which brings serious potential safety hazards to the well control work. Using the three-dimensional flow field analysis software of computational fluid dynamics (CFD), it is found that the velocity on the left wall is greater than that on the right. The field failure investigation also proved that the erosion damage mainly occurred on the left wall of the throttle valve, which verified the failure causes of the throttle valve core and valve seat. In addition, the flow field of the erosion resistance device is numerically simulated. The results show that under the given boundary conditions, when the fluid passes through the inlet and outlet of the erosion resistance device, the average velocity changes little. It is known from the velocity curve that under a certain flow rate, the smaller the overflow area is, the greater the velocity is, which is consistent with the hydrodynamic control equation. From the velocity curve data on the alloy head, it is found that the velocity changes little and tends to be horizontal, and the surface velocity of the alloy head is relatively flat, which shows that the fluid velocity on the wall can be effectively reduced after adding the stab prevention short section, so as to reduce the erosion on the wall.

Published: July 2021

In the present study, numerical analysis of coiled tube heat exchanger used in J-T refrigerator is carried out. A computer code is developed to estimate the length of the heat exchanger by giving mass flow rate, diameter of tube and shell as input parameters. This code is verified against experimental data. Two different configurations are considered in this study viz., heat exchanger with wire fin wound around the inner tube of heat exchanger and without wirefin. Three different refrigerant mixtures are used to evaluate the performance of heat exchangers. The variations of temperature and heat transfer coefficient are brought out as result. Significant reduction in the length of heat exchanger is observed in all the cases. Mixture-1 causes 33% reduction in length of heat exchanger with wirefin. Similarly, for mixture-2 and mixture-3 the length is reduced by 15% and 30%. Additionally, heat transfer coefficient (HTC) values are also estimated for heat exchanger with wirefin and without wirefin. Considerable increase in HTC values is observed in the heat exchanger with wirefin.

Published: July 2021

In summer, the utilization of solar energy can possibly satisfy the water demand. This paper examines the fluid flow in solar pump systems with solar cells. Specifically, a solar pump system model was designed and subjected to an installation test. The model consists of two solar cell units connected in series, which generate electricity and flow into the pump system. By the principles of fluid mechanics, the test results were analyzed to optimize the pump efficiency. The analysis shows that the solar cell efficiency is influenced by solar intensity, while the pump loss is maximized by fluid friction. In addition, pressure increase could affect the time of water filling; the voltage and current tend to be stable or constant.

In the present study, the slow and steady flow of Newtonian fluid in the presence of heat transfer in annular region formed by two concentric ellipses is considered. The concentric ellipses in z-plane are mapped to concentric circles in ζ-plane using conformal transformation. Analytical solutions for velocity and temperature are obtained in ζ-plane and the same are graphically depicted. The effects of dimensionless parameter such as Grashof number Gr, heat flux β, initial temperature at wall of inner ellipse θ0 and area of cross section of concentric ellipses on velocity, rate of flow and temperature have been studied. The graphical representation shows that the velocity, temperature is enhanced with increase in Gr and area of cross section between ellipses, and decreases with increase in heat flux β.
A Component Based Framework to Enable Medical Devices Communication
Authors: Touahria Imad Eddine , Khababa Abdallah
Published: July 2021

The interconnection of medical devices is emerging as a new requirement in modern medicine. The final goal of connecting heterogeneous medical devices in a wider network of computational servers is to monitor and improve patient safety, where it also constitutes a major goal in the Integrated Clinical Environment (ICE) framework. The heterogeneity of medical devices provided by different suppliers is a key challenge in ICE-based systems, where interoperability and data communication across devices is still under study and specification. ICE aims to create a standard interface that covers medical devices heterogeneity, hence, achieving interoperability in a safe way. It focuses on defining an interoperable bus between the patient, medical devices, software applications, and the clinician. Given the lack of realization of ICE standard, this paper presents a component-based framework for making ICE usable for medical applications. This work illustrates the component model in detail and validates it with a prototype implementation that focuses on the integration of heterogeneous medical devices as the most relevant requirements faced by ICE.
Mineral Associations of Veins with Quartz of the "Diamonds оf Donbass" Type in the Seleznevsky Coal-Bearing District (Folded Donbass)
Authors: Krisak Oleg S. , Popov Yuri V.
Published: July 2021

The authors have established quartz and quartz-carbonate veins, the formation of which is associated with a low-temperature hydrothermal system of methane-water composition within the Seleznevsky coal-bearing region of the Folded Donbass. The article considers the features of localization of hydrothermal mineralization containing quartz with inclusions of hydrocarbons, and its potential ore content. It is established that the vein bodies are localized mainly in the near-hinge parts of the third-order brachianticlines in the central and marginal parts of the Seleznevskaya syncline. These veins form systems associated with the fracturing of the inter-layer stratification or intersecting the layers. Interplastic veins are subdivided into plate-like massive and vein-like bodies with a druze texture. The veins of the second type contain quartz crystals with hydrocarbon inclusions, referred to as "diamonds of Donbass". They form a paragenetic association with dickite. In addition, calcite in the form of short-prismatic crystals is a typical associated mineral in the vein bodies among limestone strata. In the veins among the sandstone layers, the association with goethite, oxides and hydroxides of manganese is developed. Two morphological types of cinnabar were found in the vein bodies on the basis of HMS sampling, the largest number is confined to the brachianticlines of the marginal parts of the Seleznevskaya syncline. The analysis of the results indicates the prospects for identifying mercury mineralization with quartz-dickite-cinnabar type of mineralization.
Peculiarities of Interaction of Underground and Surface Water in Zones of Disjunctive Tectonic Faults (on the Example of Eastern Donbass)
Authors: Sklyarenko Grigory Yu. , Zakrutkin Vladimir E. , Gibkov Eugeny V.
Published: July 2021

Eastern Donbass, where coal has been mined for over a century, has become a natural-technogenic system (NTS), affecting all components of the natural environment. Among the elements most affected by it are groundwater and surface water exposed to mine waters. The state of the NTS is due to the interaction of technogenic and natural factors such as the geological structure of the territory. For many years, the environmental assessment has taken into account the organized discharge of mine water. At the same time, this region is characterized by widespread development of disjunctive tectonic faults. The hypothesis seems logical that not only the treatment facilities of closed coal mining enterprises, but the faults and associated fracture zones are channels for the drainage of mine water and deep highly mineralized solutions to the surface, where they are unloaded into the river network. Studies carried out in one of the promising areas, where drainage of groundwater takes place through fractured rocks developed along the fault displacement fault, showed their significant impact on the composition of the surface waters of the river Small Nesvetay. Taking into account the very complex tectonics of the Eastern Donbass, it would be logical to assume a similar influence of other numerous disjunctive structures. Their study will contribute to a comprehensive assessment of the region's environment and the adoption of management decisions, and the development of effective measures for water purification and stabilization of the ecological and social situation in the region.

Napoleon’s Russian campaigns one of the best known examples of the impact of weather conditions on the process of military actions. In the article, on selected examples, the influence of weather on the actions and condition of both armies, mainly the Great Army, is analyzed. Adverse weather conditions accompanied the 1812 warfare from the very beginning in the form of a storm that took place at the turn of June and July. Then a period of intense heat began, which caused considerable problems for the soldiers moving in fast marches, who were also deprived of access to drinking water. Finally, the extremely cold winter, even for Russia’s climate, contributed, however not always directly, to deaths of many soldiers on both sides of conflict. Although weather is difficult to see as the main cause of Napoleon’s defeat, it was an extremely important part of 1812 military actions.

Authors: . Suwarto , Asih Retno
Published: July 2021

Background: Low soil organic carbon is a constraint to cassava tuber formation. Some legume cover crops could be an alternative to provide organic matter on the cassava field as a source of soil organic carbon. The study was aimed to evaluate the growth of some legume cover crops under cassava and their effects on soil properties. Methods: During September 2017-July 2018 legume cover crops (Calopogonium mucunoides, Centrosema pubescens, Pueraria javanica and the mixed) were planted under cassava variety of Mangu and UJ-5. The land coverage by the legume cover crops was measured monthly from 2 to 10 months after planting. Cassava growth was observed weekly from 8 to 32 weeks after planting. Soil properties were analyzed before planting and at harvesting of cassava. Result: Pueraria javanica was tolerant toward cassava shading. The land coverage was linearly increased along with the growth of cassava. At the end of cassava growth, the land area coverage by this legume cover crop was 98.08%. It produced more organic matter and could maintain soil moisture content than other legume cover crops. P. javanica could consider being a suitable legume cover crop under cassava to improve soil quality.

Chemistry as a subject is seen by many students as an abstract and difficult lesson that bears no relationship to life. This study aimed to develop an ‘Anxiety Scale for Chemistry’, which is essential to setting an alternative for existing tools to determine anxiety for chemistry of students. This study has been carried out to develop a tool to measure the level of anxiety of students studying in the high schools in Turkey. The scale was developed as a result of the following processes: literature scan and creation of the item pool, taking expert opinions, item-total correlation, item distinctiveness features, exploratory factor analysis, Cronbach’s alpha internal consistency reliability, examination of correlation between sub-dimensions and confirmatory factor analysis. According to the results obtained, the scale is acceptably reliable for the research in social sciences. This study recommends that the Anxiety Scale for Chemistry should be administered to students of other fields also.

Media literacy at the county councils of experts in Croatia: The perspective of senior advisors for primary education
Authors: Vanek Katarina
Published: July 2021

The aim of this paper is to gain an insight into the professional development of Croatian primary education teachers when it comes to informing about media literacy at their County Councils of Experts (CCE) from the perspective of senior advisors for primary education. Five senior advisors were interviewed, and they pointed out that media literacy has sometimes been the topic at the councils, but they consider that it should be more often discussed. The results show that Croatian teachers mostly get information about the theoretical background and present examples of good practice. There are a lot of improvements which might be carried out to encourage media literacy. The results suggest anticipating greater importance to media literacy and the recognition of its importance by the Croatian authorities. Croatian primary education teachers are poorly informed about media literacy at their CCE. These results can be a starting point for further research.

 

Keywords: Councils of experts, media literacy, primary teachers, senior advisors, professional development.
Aspectos sociodemográficos y estilos de vida asociados a errores de refracción en población infantil en Bogotá, Colombia
Authors: Gutiérrez Rodríguez Jeimy Natali , Rodríguez Hilarión Javier Andrés , Avendaño Vásquez Carlos Javier
Published: July 2021

El objetivo del presente artículo es analizar la asociación de los errores de refracción en niños de 4 a 10 años con los factores que se relacionan con ellos. Este consistió en un estudio descriptivo transversal con abordaje cuantitativo, realizado en dos sedes de una institución educativa, con muestreo probabilístico y participación de 233 niños en 2018. El error de refracción (ER) se diagnosticó bajo cicloplejia. Para identificar el estado nutricional se hizo la medición e interpretación del peso y la talla. Los datos sociodemográficos se obtuvieron por medio de una encuesta, y los estilos de vida saludable se midieron mediante un cuestionario sobre riesgos de la salud en niños y adolescentes. La prevalencia de hipermetropía, astigmatismo y miopía en niños fue de 37 %, 21 % y 2,2 %, respectivamente. No se demostró asociación de los ER con el sexo de la población ni con las condiciones socioeconómicas de los padres. Respecto a la edad, se presentó una asociación directamente proporcional en niños con astigmatismo y miopía, e inversamente proporcional en niños hipermétropes. Se destaca la mayor frecuencia de niños con desnutrición aguda e hipermetropía, y la mayor ingesta de desayunos saludables y lácteos por día en niños emétropes en comparación con los hipermétropes. Como conclusión se obtuvo que la prevalencia de hipermetropía fue la más alta y la miopía la más baja en el grupo analizado. Este primer grupo realiza más actividad física que los niños con otros ER. Además, no se encontró asociación estadística entre las variables de nutrición ni sueño y descanso con los ER.
Escuela Superior de Artes Aplicadas en San Juan de Lurigancho Énfasis: Espacio intermedio como potenciador de intercambios
Authors:   , Quinteros Landeo Alvaro Alonso
Published: July 2021

El proyecto consiste en la creación de una Escuela Superior de Artes Aplicadas, la cual estará ubicada en el distrito de San Juan de Lurigancho en Lima, Perú. Las Escuelas de Educación Superior son instituciones educativas que pueden estar destinadas a impartir su enseñanza en el campo de la ciencia, la tecnología o las artes. En Lima existen muy pocas escuelas que se dedican a la enseñanza especializada de las artes, las instituciones más representativas se encuentran ubicadas en distritos céntricos, dejando así una demanda por cubrir hacia los conos de la ciudad. Este déficit de instituciones artísticas, responde a la poca difusión y a la falta de interés por el arte en el país, esto conlleva a que las carreras artísticas no sean tan tomadas en cuenta y se les reste importancia. Por estas razones, se plantea la creación de una Escuela Superior de Artes Aplicadas, la cual tendrá como objetivo brindar conocimientos especializados, enfocandose en enseñar arte y a la vez actividades conexas las cuales le permitan al alumno generar ingresos económicos haciendo uso de su creatividad para materializar sus ideas.
Propuesta de un sistema básico de gestión para mejorar la productividad de la Panadería Cosmos usando herramientas de caracterización de procesos

Published: July 2021

El problema principal que se desarrolla en la tesis es la existencia de un alto volumen de pan que no se llega a vender, seguido del atraso en la entrega de insumos y la presencia alta de mermas en el proceso de producción. Las micro y pequeñas empresas aportan aproximadamente el 24% al PBI nacional y dan empleo al 75% de la PEA. Las Mypes que se dedican a la elaboración de panes, durante el primer trimestre del año 2018 tuvo un crecimiento del 4.1% con respecto al año anterior. Tomando en cuenta la importancia del sector, es importante fortalecer su desempeño en un mercado muy competitivo. En ese sentido, se llevó a cabo una revisión literaria con el fin de dar solución al problema encontrado. Existen investigaciones donde se implementa la estandarización del trabajo, modelado de procesos y planificación de producción. Sin embargo, todos los casos de estudio de esas investigaciones son empresas con un buen nivel de madures o difieren mucho de la realidad de las microempresas peruanas. Por todo lo dicho anteriormente, en la presente tesis se propone un sistema básico de gestión que ayuda a reducir los tres principales problemas expuestos. Este sistema lo componen tres procesos, gestión de calidad, planificación y control de la producción y gestión logística. Así mismo, cada proceso tiene herramientas como el modelado de proceso, Sipoc, indicadores y formatos. La implementación del sistema se llevó en la panadería Cosmos y se obtuvo un aumento de la productividad de 89.90% a 94.81%.
