Authors:   E.A. BuketovKaraganda University, Karaganda, Kazakhstan, Tleubergenova A.Zh.
Published: July 2023

In this article, a wind power plant with a horizontal axis of rotation operating under conditions of variable wind speeds is considered. For this purpose, a mock-up of a wind power plant with rotating combined blades was made. During the experiments, the angle of the fixed blade relative to the cylinder changed from 0° to 60°, in increments of 15 °. The air flow rate varied, from 3 to 12 m/s. The analysis of the results of the experiment on the change of the rotation frequency from the air flow velocity of the wind power plant is carried out. When changing the position of the fixed blade (0°, 15°, 30°, 45°, 60°) the value of the thrust force changes relative to the air flow in direct proportion. As the air flow velocity increases, the rotation frequency of the wind wheel increases linearly. It was found that when the fixed blade was positioned at an angle of 60 degrees, with a maximum air flow velocity of 12 m/s, the thrust force reached 2.06 N. Due to the combined use of two lifting forces, such as a cylinder and a fixed blade, increased thrust values are observed.The results obtained are useful when creating prototypes of a wind power plant with combined blades.

Authors:   Kazan National Research Technical University named after A.N. Tupolev, Kazan, Russia, Usenkov R.A.
Published: July 2023

The operation of many of the engineering systems that are necessary for the functioning of a detached residential building depends on specific sources of alternative energy, the use of which can significantly reduce the consumption of traditional fossil energy resources. A review of scientific works devoted to the operation of engineering systems using alternative energy sources is given. Several schemes of power equipment have been developed to obtain thermal and electrical energy supplied to isolated consumers. When designing a fixed technical solar system using solar radiation for operation, the locations of all power equipment, the solar receiver pitch on the roof of the building and the values of its optimal angle of inclination to the horizon were determined. A scheme of a small transportable hydroelectric power plant has been developed, which generates electric energy using the pressure created by the flow of water. A thermal refrigeration unit is designed, which uses the heat of the air removed from the animal stall to heat the heated medium.

The effect of coatings with surface-active properties and aerothermoacoustic treatment on Mo and Nb stampability, mechanical properties, and microdistortions of the crystal lattice is considered.An improvement in the quality of products obtained by drawing using these technologies has been established due to an increase in plasticity and a decrease in microdistortions of the crystal lattice. Modification of the surface of the tool reduces distortion in the micro-regions of the crystal lattice, reducing the stresses of the 2nd and 3rd kind of deformed Nb and improving its formability and the quality of semi-finished products and finished products. Low formability of Mo and Nb is associated with the presence of brittle phases of lamellar and sharp-edged shape, which reduce ductility and toughness.For Nb, an additional negative factor is the presence of grains up to 40–50 μm in size.

Published: July 2023

In 1997 Mexico implemented the Management Units for the Conservation and Sustainable Use of Wildlife (UMA by its initials in Spanish) scheme. However, socio-environmental problems and the lack of a multidisciplinary approach prevented it from offering sustainable solutions. Taxonomic and functional diversity in UMAs and their interactions are essential for the preservation of biodiversity and the processes that maintain their ecosystemic integrity. Ecological benefits are insufficient without a multidisciplinary vision. This article addresses a proposal for the management of UMAs and other conservation schemes with three objectives: (1) to include the “socio-ecological system” approach; (2) the recognition of their complexity; and (3) the epistemological transition from ecosystem integrity to antifragility. UMAs constitute integral socio-ecological systems that manage wildlife and habitat as a complex adaptive system precursor to ecosystem antifragility.

La diversidad taxonómica y funcional en UMA y sus interacciones son imprescindibles en la preservación de la biodiversidad y los procesos que mantienen su integridad ecosistémica.

Quantile regression for identifying latent structures in COVID-19 pandemic – Examples from Nepal
Authors: Devkota Jyoti
Published: July 2023

During the COVID-19 pandemic, daily infections exhibited different pattern. It multiplied at an exponential rate, in the beginning. Due to physical restrictions imposed during the lockdown, this number stabilized to a certain value. During the relaxation of lockdowns, the pattern took another form. And after the distribution of three doses of vaccines, this number showed a different trend. In this paper, the path traced by the dependent variable Daily Infected, is explained using quantile values and quantile regression. The time period is from 26 February 2020 to 25 January 2023. Two quantile regression models are developed here. First, quantile regression of daily infection on daily discharged, phase and time of infection and phase time interaction is done for Nepal. Then, quantile regression of daily infection on Ratio 2, phase, time and phase and time interaction is constructed. Ratio 2, is the ratio of total new cases to total deaths, measuring the contribution of total deaths to total infected. The second model is tested for Nepal, India, Germany and the Netherlands. The behavior of the quantiles, before and after vaccination is compared. Here, Germany and the Netherlands are adjoining countries with good quality data. And Nepal and India are taken here as examples of neighboring countries with underreporting of daily infection and deaths. It is found that, quantiles and quantile regression are more robust with respect to underreporting. Thus, the latent behavior of daily incidence of COVID – 19 in different countries with different qualities of data is compared.

Published: July 2023

Hybrid microgrids run by renewable energy sources are gaining popularity around the world. Solar (PV) and permanent magnet synchronous generator (PMSG) based wind energy systems (WES) are well-known and easy to install renewable energy options. Unfortunately, wind speeds and solar irradiance levels fluctuate unpredictably. Energy generation from both WES and PV panels must therefore fluctuate. Simultaneously, the load is fluctuating irregularly. Hence, storage devices must be incorporated into hybrid systems in order to keep the generation and consumption of electricity in equilibrium. In addition, for a fuel cell and electrolyzer that run on hydrogen, a tiny battery is added into the system to keep costs down. In order to enhance power quality and reliability, all the components in a microgrid need to be connected to an effective energy management system. For optimal use, renewable energy sources are combined with maximum power point trackers. When there are sudden shifts in both the energy supply and demand on a standalone microgrid, the energy balance and frequency response are crucial. In this study, a Takagi Sugeno based innovative fuzzy controller is implemented for a system to manage energy in order to achieve a precious and rapid reaction. The suggested system's Hardware-In-the-Loop is built using OPAL-RT modules in order to demonstrate detailed findings.

Published: July 2023

The article summarizes the trends in the development of international tourism, highlights the problems and prospects of international tourism policy in post-war Ukraine. It is emphasized that thanks to the corona virus pandemic, as well as the complex geopolitical situation due to the military invasion of the Russian Federation on the territory of Ukraine, significant shifts in the overall structure of demand for tourist services are taking place all over the world. The restoration of the tourism industry is possible only under the condition of the cessation of hostilities of the Russian Federation and the rational redistribution of budget funds, reparations, and international financial aid funds between priority sectors of the economy, but the amount of these funds will depend on the conditions of peace won by Ukraine.

Published: July 2023

The article researches the development of tourism during 2000–2022 in the world and in Ukraine. Considerable attention is paid to the impact of the war in Ukraine on tourist flows both in the country and in the world. It was established that in the first half of 2022 there was a significant drop in air transport in European countries as a result of the war, where Moldova, Romania, Slovenia, Latvia, Finland and the Czech Republic were the most affected. An analysis of the dynamics of intra-European travel and air transportation showed that from mid-2022 there was an increase in the number of tourists, with a certain excess of indicators to the level of the pandemic. According to individual tourist destinations, there was a qualitative increase in the number of tourist arrivals in 2022, with positive forecast growth in the coming years, in countries such as France, Spain, Italy, Greece and Germany. It is determined that tourism in the world and in Ukraine had slightly different trends in development, where the impact of global events on the drop in tourist flows, in particular, the financial crisis and the pandemic, became common. However, the rate of development of tourism in Ukraine exceeded that of the world, where there was an increase in the share of domestic tourists who were served by tourist enterprises (after 2008). The analysis of the development of tourism in Ukraine during 2000–2022 showed that after Euro-2012 the inflow into the country began to decrease, which was significantly affected by the events of 2014. The work pays attention to the dynamics of the number of tourist operators and travel agencies (2000–2020) and key results of their activities. It is noted that in 2022 there was an increase in the payment of the tourist tax due to internal displacement due to the war. At the same time, the number of tourist enterprises has decreased. Using the example of the leading tourist operators of Ukraine, their activities during the war were considered, where it was determined that there was a change in the formats and types of tourist activities. The current trends in the development of tourist activity are considered, where the safety of tourists, the reduction of the depth of the order and the cost of the tourist ticket, as well as the change in the preferences of the tourists themselves regarding recreation with the predominance of solo tours and the use of OTA channels are considered.
Cold War and Biopolitics: Demography in Asia-Pacific during the Twentieth Century
Authors:   Korea Association of World History and Culture, Lee Dong-Kue
Published: July 2023

The primary goal of this paper is to examine the biopolitics of Asia-Pacific as a geographical area after the Second World War. The term Asia-Pacific is defined as the so-called free world, a cluster of non-communist states in the region. Turbulent political and economic years in Asia-Pacific drove America to take a deep interest in the region. America has increased its political and economic assistance in the region since 1945. This expansionist strategy resulted in the preponderance of American power in the Philippines, Southeast Asia, Indonesia, and India. Thousands of American military forces, diplomats, missionaries, technical workers, businesspeople, and even travelers have visited Asia-Pacific over the years. I focus on a series of writings on demographic studies to investigate biopolitical ideas regarding the Asia-Pacific region. In addition, James A. Michener was a proponent of building Americans’ awareness of Asia. He explored many countries, met diverse people, and shared his experiences in his publications. He supported the goals of American foreign policy in the Cold War era, claimed that the importance of the Asia-Pacific region should not be underestimated, and reflected the demographic idea.
The achievements and limitations of military construction in the early days of the Chinese Communist Party(1924-1933)
Authors:   Korea Association of World History and Culture, Ki Se-Chan
Published: July 2023

This article aims to understand the military strategy of the Chinese Communist Party more clearly by clarifying its achievements and limitations through a study on the military construction in the early days of the Communist Party of China. The CCP pursued a revolution through force, but this was impossible without building a strong military. The First United Front(國共合作) provided an opportunity to expand the power of the Chinese Communist Party within the organization of the Nationalist Party and to secure military cadres capable of building military power at the Huangpu Military Academy. Although it was insignificant in terms of taking over the overall military power, the First United Front gave the CCP an opportunity to develop into a revolutionary force by independently possessing an army. The Communist Party of China, which experienced several failed armed uprisings, tried to build its own revolutionary army.
The Chinese Communist Party made efforts to normalize the military by reorganizing the military command organization, enacting military regulations, and establishing special military units and military schools. As a result, between 1930 and 1931, the main force of the Red Army increased to 150,000, and the operational capabilities of the Red Army also improved. In terms of doctrine, the Red Army also established basic tactical principles such as the 16-character formula(十六字戰法). In general, it cannot be denied that the Chinese Communist Party’s series of measures and efforts for military construction, which began in 1930, improved the Red Army’s ability to wage war to a certain extent. However, considering that the Red Army did not have the ability to produce even basic weapons on its own, military construction in the early days of the CCP clearly had its limits.
Pareto-based design of experiments for identifying and comparing optimum sealing parameters of heat sealing applications in packaging machines
Authors: GELLERICH PETER , MAJSCHAK JENS-PETER
Published: July 2023

Sealing is one of the most important process steps in industrial packaging, because the sealed seam is the most sensitive section of a package in terms of quality. For this reason, a major focus in flexible packaging is the sealing process, and among this, heat sealing is the most frequently used technology. In detail, applications of heat sealing processes are confronted with four conflicting objectives: increasing seam quality, reducing dwell time, reducing sealing temperature, and increasing process robustness towards varying conditions. Typical problems, such as identification of the optimum process parameters or selection of the most appropriate packaging film, are subject to these conflicting objectives. This paper presents a recently published design of experiments for characterizing and comparing heat sealing properties of packaging films based on a multi-objective optimization algorithm. The approach provides easy-to-read charts showing all optimum sealing parameters with regard to the four essential objectives of heat sealing: seam quality, dwell time, sealing temperature, and process robustness. Three case studies show exemplary applications of the new approach: 1) analyzing transport damages of beverage powder packages; 2) identifying and comparing optimum sealing parameter of a standard, mono-material, and fiber based packaging film regarding tightness and visual properties of the produced sachets; and 3) analyzing the effect of additional aluminum layers on sealing characteristics regarding hot-tack.The new design of experiments may provide the basis of a standard test method for the identification of optimal sealing parameters in the heat sealing processes.

Regional Regulation Number 11 of 2017 concerning Organizing Sports is the key to the development of sports, especially educational sports. This Regional Regulation places sport as a very important instrument for regional development. However, at this time, sports are still positioned only as the development of the sport itself. So it is not in accordance with what is stated in Regional Regulation Number 11 of 2017. Therefore, the purpose of this study is to find out the Policy for Development and Development of Sports Education from the Perspective of Regional Regulations. The method used in this research is to use a descriptive qualitative approach. Then by making observations, documentation studies, and interviews as a tool for collecting data and for analyzing the data. The results of this study found that the Policy for Development and Development of Sports Education from the Perspective of Regional Regulations was in accordance with Regional Regulation Number 11 of 2017 concerning Organizing Sports. However, there are still deficiencies and inequalities in several aspects such as facilities and infrastructure, the competency of sports teachers who do not yet have competency certificates from the main sports branch and the uneven distribution of schools in implementing special sports class programs.

Right ventricular myxoma is a very rare location of cardiac myxomas. The most common complications are pulmonary embolism and tumor obstruction of the pulmonary valve. We report the case of a 63-year-old woman admitted to Cardiology for recurrent syncope and progressively worsening dyspnea. Echocardiography revealed right atrial myxoma. Surgical excision was performed under extracorporeal circulation, with favorable postoperative outcomes. Histological examination of the specimen confirmed the diagnosis of myxoma. The 2-month follow-up does not show any tumor recurrence.

Land surface air temperature in Asia has been increasing significantly since the 1950s. However, current understanding of Asian warming since 1901 in terms of observations and simulations is still poor. Based on a newly developed observation dataset with 2658 stations and Coupled Model Intercomparison Project Phase 5/6 (CMIP5/6) output data, we analyze changes in mean (Tmean), maximum (Tmax), and minimum (Tmin) temperature, and diurnal temperature range (DTR) over Asia during 1901-2100. Annual mean land surface air temperature over Asia increased significantly, and Tmean, Tmax, and Tmin increased by 1.81, 1.47, and 2.15°C during 1901-2020, respectively. The Tmin warming rate is about 1.5× that of Tmax, resulting in a decline of Asian DTR by 0.68°C since 1901. We also found that Asia has experienced more substantial warming than the global case and the Northern Hemisphere, and the decline in DTR is more substantial in Asia. Spatially, Asia exhibits a general warming trend with a gradual increase in spatial warming from low to high latitudes, and the effect of high-latitude warming has gradually strengthened since the 2000s. Seasonally, Asian warming in the cold season is stronger than in the warm season. Furthermore, CMIP5/6 can capture the Asian warming in the historical period 1901-2020. However, it underestimated Tmin and overestimated Tmax, contributing to their poor performance in simulating the historical change of DTR. Under Shared Socioeconomic Pathway (SSP) 2-4.5, Asian Tmean, Tmax, and Tmin are projected to increase by 3.5, 3.4, and 3.7°C century-1 during 2021-2100, respectively. The Asian warming rate under SSP5-8.5 is about 2× that of SSP2-4.5.

Lactococcus petauri is an important emergent aquaculture pathogen in the USA. To better understand environmental conditions conducive to piscine lactococcosis and the susceptibility of fish species, laboratory-controlled challenges were used as models of infection. Rainbow trout Oncorhynchus mykiss maintained at 13 or 18°C were challenged by intracoelomic (ICe) injection with 101, 103 or 105 colony-forming units per fish (CFU fish-1) and monitored for 21 d. At 13°C, trout experienced mortalities of 7, 7 and 0%, and bacterial persistence of 0, 20 and 0% in survivors, respectively. When exposed to the same bacterial doses, trout maintained at 18°C experienced mortalities of 59, 84 and 91%, and bacterial persistence of 60, 66 and 0% in survivors, confirming a significant role of temperature in the pathogenesis of lactococcosis. Additionally, the susceptibility of rainbow trout, Chinook salmon Oncorhynchus tshawytscha, white sturgeon Acipenser transmontanus, Nile tilapia Oreochromis niloticus, and koi Cyprinus carpio to infection by L. petauri was compared using ICe challenges at 18°C. Trout and salmon experienced 96 and 56% cumulative mortality, respectively, and 17% of surviving salmon remained persistently infected. There were no mortalities in the other fish species, and no culturable bacteria recovered at the end of the challenge. However, when surviving fish were used in further cohabitation trials, naïve trout housed with previously exposed tilapia exhibited 6% mortality, demonstrating that non-salmonids can become sub-clinical carriers of this pathogen. The data obtained provide useful information regarding temperature-associated virulence, fish species susceptibility, and potential carrier transmission of L. petauri that can be used in the development of better management practices to protect against piscine lactococcosis.

Purpose: Insufficient osseointegration and implant-associated infection are major factors in the failure of Ti-based implants, thus spurring scientists to develop multifunctional coatings that are better suited for clinical requirements. Here, a new biomimetic micro/nanoscale topography coating combined with antibacterial copper was simultaneously designed for Ti-based implant surfaces by adopting a hybrid approach combining plasma electrolytic oxidation and hydrothermal treatment.

Results: The biological interactions between this biofunctionalized material interface and stem cells promoted cellular adhesion and spreading during initial attachment and supported cellular proliferation for favorable biocompatibility. Bone marrow mesenchymal stem cells (BMMSCs) on the coating displayed enhanced cellular mineral deposition ability, higher alkaline phosphatase activity, and upregulated expression of osteogenic-related markers without the addition of osteoinductive chemical factors, which improved osseointegration. More interestingly, this new coating reduced the viability of oral pathogens (Fusobacterium nucleatum and Porphyromonas gingivalis)—the primary causes of implant-associated infections as indicated by damage of cellular structures and decreased population. This is the first study investigating the antibacterial property of dental implants modified by a hybrid approach against oral pathogens to better mimic the oral environment.

Conclusion: These findings suggest that biofunctionalization of the implant coating by surface modification methods and the incorporation of antibacterial copper (Cu) offer superior osteogenesis capability and effective antibacterial activity, respectively. These strategies have great value in orthopedic and dental implant applications.
Staphylococcus epidermidis biofilms undergo metabolic and matrix remodeling under nitrosative stress

Published: July 2023

Staphylococcus epidermidis is a commensal skin bacterium that forms host- and antibiotic-resistant biofilms that are a major cause of implant-associated infections. Most research has focused on studying the responses to host-imposed stresses on planktonic bacteria. In this work, we addressed the open question of how S. epidermidis thrives on toxic concentrations of nitric oxide (NO) produced by host innate immune cells during biofilm assembly. We analyzed alterations of gene expression, metabolism, and matrix structure of biofilms of two clinical isolates of S. epidermidis, namely, 1457 and RP62A, formed under NO stress conditions. In both strains, NO lowers the amount of biofilm mass and causes increased production of lactate and decreased acetate excretion from biofilm glucose metabolism. Transcriptional analysis revealed that NO induces icaA, which is directly involved in polysaccharide intercellular adhesion (PIA) production, and genes encoding proteins of the amino sugar pathway (glmM and glmU) that link glycolysis to PIA synthesis. However, the strains seem to have distinct regulatory mechanisms to boost lactate production, as NO causes a substantial upregulation of ldh gene in strain RP62A but not in strain 1457. The analysis of the matrix components of the staphylococcal biofilms, assessed by confocal laser scanning microscopy (CLSM), showed that NO stimulates PIA and protein production and interferes with biofilm structure in a strain-dependent manner, but independently of the Ldh level. Thus, NO resistance is attained by remodeling the staphylococcal matrix architecture and adaptation of main metabolic processes, likely providing in vivo fitness of S. epidermidis biofilms contacting NO-proficient macrophages.

Published: July 2023

Previous qualitative research has explored how adolescents conceptualise loneliness, but, there is currently no examination of whether loneliness is understood differently by adolescents in different countries. To address that gap, the current study used semi-structured interviews to explore what loneliness is, and how to cope with it, from the perspectives of 29 adolescents (15 male, 14 female), aged 14–16 years from Lithuania (n = 6), Poland (n = 5), Portugal (n = 6), Serbia (n = 6), and Turkey (n = 6). Convenience sampling was used to recruit participants via project partners. Participants were included if they were aged 14–16 years, attended a school, youth centre, or foster home included in the Fit to Belong Erasmus+ Project, and did not have any disabilities or impairments that would impact their participation or understanding of the research activities. Thematic Framework Analysis (TFA) was used to analyse interviews with the adolescents and develop themes that reflected adolescents’ nuanced accounts of loneliness. Themes and subthemes described loneliness as a negative emotional experience involving a lack of belonging to one’s social environment and difficulty opening up to others. Themes recommended coping strategies for loneliness. Adolescents in the different countries described loneliness similarly: they understand it to involve negative emotions, and a lack of belongingness to one’s social environment, often due to social exclusion. Future research should explore the appropriateness of current measures and interventions that are used to address loneliness in youth and how those can be enhanced by including youth perspectives in the development process.
