Evaluation of the Rehabilitation Effect of Nanometric Ion Medicine Steam Combined with Facial Muscle Training in the Treatment of Post-Stroke Peripheral Facial Nerve Palsy

This work aimed to investigate the rehabilitation effect of nanometer ion medicine steaming combined with facial muscle training in the treatment of post-stroke peripheral facial nerve palsy (PFNP), and to analyze the therapeutic effect of artificial skin continuous negative pressure drainage on stroke pressure ulcers. 120 patients with post-stroke PFNP who were admitted to Qilu Hospital (Qingdao), Cheeloo College of Medicine were recruited and rolled into the medicine steaming group (MS group, nanometer ion medicine steam) and the joint group (J group, nanometer ion medicine steam plus facial muscle training). The treatment effects, facial functional recovery, and pressure ulcer treatment outcomes were compared between patients in different groups. Results: After treatment, the facial disability index scores and facial nerve function scores of both groups of patients greatly increased, with a more drastic increase in J group (P < 0.05), so did the scores of various traditional Chinese medicine symptoms (P < 0.05). Furthermore, the proportion of patients in J group with facial function classified as level I or level II was obviously higher (P < 0.05). The treatment effectiveness and satisfaction rate in J group were dramatically superior to in MS group (P < 0.05). Conclusion: the joint treatment of nanometer ion medicine steam and facial muscle training has a significant effect in the rehabilitation of post-stroke PFNP, with faster facial functional recovery and higher patient acceptance.

Bench studies of the influence of operating conditions on operational safety of steam turbine air-cooled condensers at subzero outdoor temperatures

Condensation processes are widely spread in various branches of industrial production and, in particular, in electric power industry, where, according to experts' data, heat removal in thermodynamic cycles of steam turbine plants (STP) operating as part of combined cycle plants (CCP) and autonomously, in the 21st century will be exercised mainly in air-cooled condensers (ACC). At the same time, the use of ACC as a part of steam turbine units operating in climatic conditions typical for the Russian Federation (RF) determines the relevance of problems to be solved to ensure their safe operation at subzero outside temperatures. One of these challenges is to ensure long-term safe operation of the ACC, with the formation of ice on the inner surface of the heat exchange pipes minimized. To conduct the research, Steam Turbine Air-Cooled Condenser research and training stand was used. The paper presents the combined circuit and measurement diagram of the research and training stand, and gives a brief description of the design of the ACC. Experimental modes have been determined, and methods for processing experimental data and analyzing the results obtained have been developed. As part of the study, experiments were carried out on 18 steady-state operation modes of the stand. At the same time, the values of the main operational parameters of the ACС varied within the following limits: the temperature of the cooling air at the ACС inlet — from minus 11,5°C to minus 1,8°C; the cooling ratio — from 176 to 790. The relative weight content of air in the vapor varied from 0,051% to 0,12%. An analysis of the obtained results was carried out, on the basis of which a relationship was established that allows, for various negative temperatures of the cooling air at the inlet to the ACС, to determine the highest value of the cooling ratio at which its long-term safe operation is possible. An algorithm for using the obtained relationship is given.

Wilhelm Stenhammar

Wilhelm Stenhammar’s contributions to Swedish musical life around 1900 are widely acknowledged. But his activities stretched well beyond the Swedish borders. The present article approaches Stenhammar from a transnational perspective, placing him in the broader context of European musical modernism around 1900. Following a clarification of the use of the terms ‘modernity’ and ‘modernism’ in the light of recent research on modernism in music, Stenhammar’s identity as a European modernist is discussed with special focus on Copenhagen and Berlin. Stenhammar’s compositional strategies in the finale of his String Quartet no. 3 op. 18 in F major are then analysed in terms of musical self-reflection, offering a new perspective on his compositional agency with a wealth of musical traditions at his disposal. At a time when travelling across borders by steam train had become a common part of modern life, transcultural interconnectedness seems to be a common framework for musicians to identify as modern composers. Keywords: Wilhelm Stenhammar, Henrik Hennings, Louis Glass, modernism, modernity, music analysis, self-reflection, European music historiography.

Figuras y geopolíticas del ruido y de la escucha: En tierra yankee (1895) de Justo Sierra

Abstract: The travel chronicles En tierra yankee (Notas a todo vapor) (1895) by Porfirian intellectual Justo Sierra Méndez lead us to reflect on the ways in which they imagined the sonic and the audible in relation to changing urban spaces, the Mexico/United States border, and communication and transportation technologies such as the steam train in unequally modernized spaces. The narrator employs a terminology of musical composition and sound to indicate the emergence of an economic and industrial hegemony that reorganized the new noises that marked the modern rhythms of the first half of the twentieth century. Noise holds a prominent place in establishing and unveiling postcolonial and racist relations with the other (the Yankee , the Afro-descendant). The nature of the travel narrative as a genre was not limited to mobilizing bodies or goods but also encompassed aural sensitivities, enabling a reflection on the geopolitics of sound, and listening. At a time when ideas and discourses are developing about the need for a Latin Americanist front to counteract North American postcolonial impact, the problematization of Latinamericanism is manifested through noise according to Sierra.

TECHNOLOGY THE FIRE DETECTION SYSTEM ON THE RAILWAY LINE IS BASED ON IMAGE PROCESSING WITH THE COMPUTER VISION METHOD

The rail transportation system plays a role important as a medium of transportation for the movement of goods and people in large quantities and is one of the modes of cheap transportation, this transportation model evolved from a steam train until it evolves to become more sophisticated using electric and magnetic technology, trains system works well with support from several the first factor is human resources, supporting technology and facilities. The problem with the rail system is that damage to the rails can cause result in the transportation route being blocked and can cause a very fatal accident, Based on these problems, besides the feasibility of the rail system, rail maintenance is a very important key, the railroad track maintenance system is usually carried out periodically. The solution to handle this problem is to use a computer vision method by utilizing surveillance cameras or CCTV installed on railroad crossings able to detect damage, the detection of damage is categorized into a few types first is track damage, due to shifts, fires on rail lines and finally structural damage due to earthquakes or landslides in the railway line area, this technology has been applied to several developed countries. and can monitor a large area and can provide a quick response if a malfunction occurs, the system will be a smart monitoring system but doesn't replace the role of a railway officer but as a tool that will provide complete information where the location of the damage is so that prompt and more effective repair action can be taken.

Environmental Sustainability in Science Education in the Anthropocene: A View from STEAM Education

Environmental problems in the age we live in require us to think differently, to question them, and to do something corrective. The role of science education in the transformation of education and its adaptation to the age is perhaps more than in previous periods. Because at the end of the day is the continuity of our planet. This article examines science education and higher-order thinking skills in the Anthropocene era and presents examples from studies on environmental sustainability as a prominent concept in this field. In addition, it argues that STEAM education is one of the ideal approaches that can meet this goal by presenting examples of what can be done with a holistic and interdisciplinary view of environmental sustainability within the framework of STEAM education. Suggestions are made through STEAM training, with the assumption that environmental sustainability in an intricately connected network structure rather than linear chains can only be understood with an interdisciplinary approach and solutions can be found only in this way.

Transforming a steam train: a historical institutionalist analysis of EU railway policy

ABSTRACT The European Commission wants to transform the railways as part of its wider sustainable transport policy agenda. However, the railways provide territorial cohesion and public services at the national level with little on-track competition or international services. The Council has resisted the Commission’s attempt to transform the railways. This article uses historical institutionalism to analyse feedback loops in EU railway policymaking, specifically analysing how the issue of EU railway governance has influenced policy development and how Council discussions concerning the opening of the domestic passenger market reveals a temporal dimension in policy development. The article shows how the Council continues both to reduce the speed and change the direction of EU railway policymaking and that the adopted policies are ambiguous and create path dependency at the EU level while retaining national-level path dependency. The article demonstrates the close relationship between historical institutionalism and railway policy in favouring stability over transformation.

INTEGRATION OF ELECTRIC VEHICLES INTO THE SMART GRID

The need of human beings to use vehicles in transportation was met first by steam trains, then by various automobiles and other vehicles working with internal combustion engines. Today, electric vehicles are increasingly used for transportation. As in all industrial establishments and cities, it has been determined as a goal to cause less damage to the environment and to use vehicles more efficiently in transportation. Due to the increase in the use of fossil fuels and the fact that these resources are facing depletion in the coming years, developed countries have started to search for new ones. The use of electric vehicles, which emerged with these studies, is becoming widespread day by day. In addition to being environmentally friendly compared to internal combustion engines, another advantage of electric vehicles is that they can work in an integrated manner with smart grids. In this study, research will be conducted on the current status of electric vehicles, their types, charge levels, advantages, difficulties in development and statistics on electric vehicle use in different countries. In addition, various concepts that emerge with the integrated use of electric vehicles with smart grids will be evaluated. The advantages of including smart grids in the electricity grid infrastructure will be examined. The working principles of vehicle-to-grid (V2G) systems will be evaluated. The concept of “demand-side participation”, which emerges with the use of vehicle-to-grid systems and contributes to the electricity supply-demand balance, will be examined.

An attempt to evaluate STEAM project-based instruction from a school mathematics perspective

Official documents in several educational systems reflect the importance of integrating Science, Technology, Engineering, Arts, and Mathematics (STEAM) and consider project-based learning (PBL) as a way of integrating such disciplines in the classroom. Although STEAM-PBL has been characterized and evaluated in different ways, its impact on school mathematics teaching remains unclear. Mathematics is recognized as the fundamental basis of other disciplines; however, many students still perceive it as a difficult subject and abandon it. To analyze STEAM-PBL classroom implementation from a school mathematics standpoint, we examined 41 classroom experiences from 11 Spanish secondary education teachers (five in-field mathematics teachers), who participated in a STEAM training program for more than 4 years. To frame this study, Thibaut et al.’s (J STEM Educ 3(1):02, 2018) and Schoenfeld’s (Educ Res 43(8):404–412, 2014) characterizations of well-designed and implemented projects, respectively, were employed. The results showed that in-field mathematics teachers avoided transdisciplinary projects in which school mathematics is difficult to address, while out-of-field teachers tended to overlook the mathematics in interdisciplinary projects. Unlike out-of-field teachers, mathematics teachers often eluded design-based learning processes for deeply exploiting school mathematics. The latter teachers promoted high cognitive demands and positive perceptions about mathematics in projects where formative environments were generated through discussion and a meaningful feedback loop.

STEM and STEAM Education in Russian Education: Conceptual Framework

The paper examines the STEM approach as one of the revolutionary tools for transforming education. This paper discloses the content of the concept of “STEAM-education”, substantiates its importance and prerequisites for its appearance. The author elucidates a comparative analytical review of trends and prospects for the development of STEAM education in the Russian Federation. In this paper, the authors want to touch upon a comprehensive theoretical and methodological study conducted on the declared problem to identify the problem of the formation and development of the STEAM approach in the education system in the Russian Federation at all levels: general education, vocational education, and additional education. The object of this study was STEM education. The subject of this research was the STEM approach and STEM technologies in the system of general education, vocational education, and additional education. The methodological foundation of the study was the general scientific propositions on the holistic, systemic, and dialectical approaches to research, which made it possible to assess the totality of interrelated and interacting elements that form a certain integrity. The use of these approaches provided a comprehensive analysis and formulation of the research problem and determined the strategy for its study. The analysis of the current state of STEM and STEAM education in higher education in the Russian Federation suggests that it is necessary to stimulate the development of information and communication technologies in the country’s education system in general, as well as to develop comprehensive programs for adapting STEM and STEAM approaches among the subjects of educational relations. In the context of modern global risks and challenges, the educational trajectory of development in Russia should be conceptually consistent with the new strategy in the field of natural science education adopted in the United States, “The Path to Success: American Strategy for STEM Education”. Experts believe that through the practical implementation of STEM and STEAM technologies, it is possible to improve the efficiency of the quality of training for the purposes of the modern digital economic sphere. In this regard, the primary competences obtained in the higher education system in the areas of STEM and STEAM training should be cognitive, personal, and interpersonal competences, expressed in digital literacy, computational thinking, creativity, open mind, soft skills, and others. The concept of STEAM education in the system of higher professional education in Russia will ensure the transformation of ideas about scientific knowledge and build an innovative development process through the formation of skills in the field of exact sciences, linguistics, engineering, art, etc.

What Went Wrong?

Governments should create IT accident investigation boards for the exact same reasons they have done so for ships, railroads, planes, and in many cases, automobiles. Denmark got its Railroad Accident Investigation Board because too many people were maimed and killed by steam trains. The UK's Air Accidents Investigation Branch was created for pretty much the same reasons, but, specifically, because when the airlines investigated themselves, nobody was any the wiser. Does that sound slightly familiar in any way?
