Published: March 2023

For sustainable development, hygiene should be specific to general, from personal hygiene to environmental cleaning, and environmental awareness of individuals should be made more permanent. It is estimated that individuals who know the importance of personal hygiene may be more sensitive to the ecological problems of their society. Individuals growing up sensitive to the environment can make the environment more livable. This study aimed to investigate the impact of variables such as gender, class level, residence, educational status of parents, type of residence of the family, hand-face washing, and frequency of bathing on the environmental knowledge of secondary school students. In the study, the survey method among descriptive research was used. The study was conducted with a total of 360 secondary school students studying in the village schools and central schools in Ağrı province in the 2018-2019 academic year. In the study, Environmental Knowledge Test (water-soil pollution) and Hygiene Information Form (face washing, bathing) were used as data collection tools, and their relationship with the variables included in the data collection tools was examined. Mann Whitney U, Kruskal Wallis Tests were used to analyze the data. As a result of the statistical analysis, a significant relationship was found between environmental knowledge and gender, class level, parental education level, and residence; however, no significant relationship was found between environmental knowledge and the frequency of hand-face washing and bathing.

Published: March 2023

The study aimed at availability of petroleum products in Nigeria through the operation of enhanced modular refinery process due to inefficient conventional major refineries. The enhanced modular refinery converts or processes residue product from conventional modular refinery as feedstock to the hydrocracker reactor for viable and desired products such as liquefied petroleum gas, naphtha and diesel. Therefore, twenty Nigerian crude oil types were classified as sweet, light and medium crude oil, and these crude oil types were categorized based on their recovery volume at true boiling point of 370oC as Group A, Group B and Group C respectively. Thus, based on product output and equipment cost, a modular refinery with 29 trays was used in this study, as light and medium sweet crude oil types were simulated in a modular refinery of various column trays prior to the desired tray. A topping plant with a 30,000 barrel per day capacity and a modified topping plant with 29 trays respectively were used to process different types of Nigerian crude oil. using Aspen Hysys to evaluate their products yield and tray compositions. The modified modular refinery with hydrocracker yielded more valuable from the residue of conventional modular refinery with minimal bottom fraction. Performance models for hydrocracker reactor was developed based on the nature of reaction, kinetic parameters estimated and results compared with experimental data with minimum deviations. The developed performance models predicted feedstock conversion and product yield along the hydrocracker reactor’s dimensionless length by solving a set of ordinary differential equation models. Thus, the hydrocracking process was simulated to evaluate the effects of catalyst effectiveness factor on feedstock conversion and products yield.

This study has been leaded to find the causes of the deviation rates beyond the tolerance. For this study, the mastery of the transfer system was decisive for the resolution of easily identifiable problems and for our guidance in the choice of methods for identifying complex problems. The methods used for this study were the graphical representation method and the ISHIKAWA diagram. The graphical representation of deviation rate (over the period of April to August) enabled us to view 35% discrepancy rates beyond the tolerance limits for the SSP and 20% for GO. Through the ISHIKAWA diagram, we highlighted the root causes of gaps in general and organized these causes into two categories that are the physical gaps and fictive gaps. The estimation of these causes has shown that errors in the temperature measurement are the source of 80% of gap rates beyond tolerance limits and 20% are divided between technical gauging errors and physical gaps (not significant). Solutions have been thereafter proposed to minimize the amount of product gaps during transfers.

Published: March 2023

Three-dimensional visualization of medical image data can enable doctors to observe images from more angles and higher dimensions. It is of great significance for doctors to assist in diagnosis and preoperative planning. Most 3D visualization systems are based on desktop applications, which are too dependent on hardware and operating system. This makes it difficult to use across platforms and maintain. Web-based systems tend to have limited capabilities. To this end, we developed a web application, which not only provides DICOM (Digital Imaging and Communications in Medicine) image browsing and annotation functions, but also provides three-dimensional post-processing functions of multiplanar reconstruction, volume rendering, lung parenchyma segmentation and brain MRI (Magnetic Resonance Imaging) analysis. In order to improve the rendering speed, we use the Marching Cube algorithm for 3D reconstruction in the background in an asynchronous way, and save the reconstructed model as glTF (GL Transmission Format). At the same time, Draco compression algorithm is used to optimize the glTF model to achieve more efficient rendering. After performance evaluation, the system reconstructed a CT (Computed Tomography) series of 242 slices and the optimized model was only 6.37mb with a rendering time of less than 2.5s. Three-dimensional visualization of the lung parenchyma clearly shows the volume, location, and shape of pulmonary nodules. The segmentation and reconstruction of different brain tissues can reveal the spatial three-dimensional structure and adjacent relationship of glioma in the brain, which has great application value in auxiliary diagnosis and preoperative planning.

Authors: Oliveira Lazaro Tiago de , Deminicis Bruno Borges
Published: March 2023

Nitrogen fertilization is an efficient practice to improve pasture productivity and quality. However, the efficiency of Nitrogen (N) application depends on favorable climatic conditions. Thus, in the present work, a metanalytic study was used to summarize and analyze data on nitrogen fertilization in forage species: elephant grass (Pennisetum purpureum) and panicum grass [Megathyrsus maximus (Syn. Panicum maximum)], in order to determine the critical levels and recommended doses of nutrients for the rational use of fertilizers in forage plants, whether in pastures or weeds. Therefore, in this study, a systematic review was used, which is a type of investigation, for which research works carried out in Brazil between 2010 and 2020 were considered, including only scientific articles and dissertations. Based on the data from these studies, the relative increments of dry matter and crude protein in relation to the control treatment and the efficiency of nitrogen use in the production of dry matter and crude protein were calculated. All data collected were submitted to analysis of variance for linear and quadratic effects on each of the variables and, in case of significance, regression analysis was performed. Nitrogen fertilization in Pennisetum purpureum and Megathyrsus maximus provides consistent increases in dry matter and crude protein production, however above 1000 kg of nitrogen ha-1 there is a compromise in the efficiency of dry matter production. With a view to reducing losses due to the lower efficiency in crude protein production, it is important to verify that above 500 kg of nitrogen, there is a drastic reduction in the efficiency of crude protein production by Pennisetum purpureum. For all nitrogen doses, there is a drastic reduction in crude protein production efficiency by Megathyrsus maximus in relation to the control.

Authors: Nikiforov S.A. , Shvarts I.V. , Gilmutdinov A.Kh. , Gorunov A.I.
Published: March 2023

The paper considers the two-phase physical and mathematical model of the AISI 316L stainless steel melting and its numerical implementation by the finite volume method in the ANSYS CFX software based on the well-known concepts of simulating the thermocapillary convection. Approximation functions are proposed to take into account the effective specific heat and dynamic viscosity in the transition process from a solid to the liquid state to minimize the numerical error in the vicinity of the liquidus and solidus temperature points. The molten pool formation process was considered under the action of laser radiation with the Gaussian intensity profile taking into account boundary conditions of the Marangoni convection, convective heat transfer and radiative heat transfer. Influence of the thermocapillary convection on the shape of the molten pool wetted surface is shown. An approach is proposed to control flows on the free surface of the molten pool by changing the laser intensity profile.

Published: March 2023

The paper considers features of regulating shock-wave structures using the gas blowing into the flow region from perforated boundaries, as well as by means of energy supply to the compression shocks. Scientists both in our country and abroad are actively studying the porous structures. Calculations in the gas dynamics software packages and using the MATLAB are making it possible to determine the flow blowing effect on rearrangement of the emerging shock-wave structures, which analysis with mathematical apparatus of the shock (detonation) polars allows evaluating their diversity with the pulsed energy supply to the compression shocks. Methods of these structures regulation under study contribute to improving characteristics of the supersonic aircraft and creation of their modernized designs taking into account transformation criteria of the shock-wave structures, which in many cases could be unstable.

Authors: Altunin V.A. , Lvov M.V. , Shchigolev A.A. , Yusupov A.A.
Published: March 2023

The article shows that various problems appear in the aircraft lubrication systems. These problems are associated with the quality of aviation motor oils, difficult thermodynamic conditions in their operation, negative sedimentation process, design features and deficiencies of piston aviation internal combustion engines, air-breathing engines, various aviation and ground power plants, as well in their filtering and cooling systems. Design and creation of new equipment foresees using aviation motor oils of various brands and properties; therefor, scientists, designers, engineers and constructors always need to know not only the selected oil general properties, but also its thermophysical properties, including density, thermal conductivity, viscosity and thermal capacity. The paper considers the issue of the MS-20 aviation engine oil density at various temperatures and pressures. A number of authors (and information sources) provide comparative data on this oil; its density values at different temperatures and normal pressure are having differences. Methods for obtaining density values of the aviation motor oils, including the MS-20 brand oils, are presented in experimental studies; in using nomograms, graphs and tables; in calculations using various techniques. The method for calculating the MS-20 oil density with an increase in temperature and pressure set out in the State Standards is demonstrated. A new abbreviated and effective method for calculating the aviation motor oils density with alterations in temperature and pressure, including the MS-20 brand oil, was developed and is presented. Recommendations are provided on the correct account of temperature and pressure when using density of the MS-20 and other types of the aviation engine oil to create new domestic ground, air, hypersonic and aerospace equipment for single-use and reusable for various purposes with improved performance in terms of resource, reliability and efficiency.

Authors: Martini Rina , Agustin Esther Sri Astuti Soeryaningrum , Setiyono Budi
Published: March 2023

This research aims to analyze factors determining the competitiveness of rural tourism and assess its performance compared to the poverty level in each province in Indonesia. We employ four main pillars: enabling environment; travel and tourism policy and enabling conditions; infrastructure; and natural & cultural resources adopted from the Travel and Tourism Competitiveness Index of the World Economic Forum 2019. We conducted fieldwork in four provinces, namely Aceh, Bali, Central Java, and North Sulawesi, by spreading  questionnaires and giving semi-structured interviews to obtain respondents’ insights. The poverty gap index measures the intensity level of poverty by employing an expenditure-based poverty line. This study discovers that infrastructure, natural & cultural resources, and enabling environment support rural tourism development in each province. We also find that the excellent performance of rural tourism competitiveness seems to have minimal impact on poverty. Bali has become the major icon of tourism in Indonesia; ironically, its poverty level is relatively higher than in other areas. Meanwhile, Central Java ranks as the second most competitive province after Bali, while the poverty level is the lowest. Our study offers community-based tourism (CBT) and corporate social responsibility (CSR) to resolve the situation.

Ekonomiczny, społeczny i egzystencjalny wymiar funkcjonowania placówek hospicyjnych i wolontariatu hospicyjnego
Authors: Rutkowska Anna
Published: March 2023

The functioning of hospice institutions may be considered based on three fundamental, functions
accomplished by it, i.e. existential, social and economic ones. Holistic evaluation of hospice care
requires taking into account actual and potential advantages, possible to achieve both through society
represented by all citizens, and through the economy.
The article has a survey character – the literature is based on critical analysis within the scope
ofthe subject raised. The work was made rich from two-year own experience of volunteer work.
For the purpose of realization of the subject raised, empirical examinations were also conducted based
on the method of shadow prices and logical matrix.
In this paper, the implementation of the function of an existential volunteer hospice is considered
on the basis of its ability to alleviate the suffering of patients’ mental and spiritual capacity and give
them practical help by volunteers. The usefulness of hospices, which is a part of their social function,
was studied by considering the point of existence and functioning of palliative and long-term care
centres. In order to define the economic function of a voluntary service, micro and macroeconomic
types of analysis were used. One should, however, emphasise that these examinations should have
an interdisciplinary character.

Introduction: Reclaiming the Cerrado – A Territorial Account of a Disputed Frontier
Authors:   Institute of Development Studies, Cabral Lídia , Sauer Sérgio , Shankland Alex
Published: March 2023

As global agri-food systems come under increasing stress, debates on their future have become highly polarised, exposing fundamental differences in understandings and priorities: industrial production versus traditional rights; short-term yields versus longer-term sustainability; cheap versus healthy food. Brazil is at the core of these debates, with the Cerrado being centre stage since the soybean-powered Green Revolution. Accompanied by deforestation, soil degradation, and depletion of water resources, Brazil’s agricultural production frontier has now moved northwards into the Matopiba region. This issue of the IDS Bulletin explores the ongoing territorial transformation, considering the violent logics of extraction in frontier zones, the grabbing of nature, and the dynamics of resistance in local and international spheres. Exposing both the material and discursive appropriation experienced by the Cerrado, this issue profiles it as a key site of multi-scalar injustices against people and nature that need to be addressed by efforts to secure more just and sustainable agri-food systems.
Mapping Fire: The Case of Matopiba
Authors: Venâncio Ramos Júnior Dernival , Gomes de Aguiar Vinicius , Kantamaneni Komali
Published: March 2023

This article examines fire as a political tool to advance the expansion of the agricultural frontier in Brazil and proposes a methodology for working with affected communities to protect their territories. Historically, fire has been used by communities as a traditional resource management strategy. However, it has also been associated with environmental degradation and agribusiness expansion. Our analysis focuses on the territories of black rural communities in Matopiba and shows how territorial conflict is now shifting to the productive spaces of these communities, indicating a politicisation of these spaces and implications for the regional agri-food system. Using satellite imagery and participatory methods, the authors worked with community members and activists to create an integrated map documenting and assessing the extent of fires in the area. The methodology developed can support the protection of areas and communities in other parts of this region and help gather evidence that can be used in court cases and support whistleblowing to the authorities.

Authors: Maia Lídia Raquel Herculano , Oliveira Thaiane , Massarani Luisa , Santos Júnior Marcelo Alves dos
Published: March 2023

Neste artigo, analisamos as características do discurso de contestação às vacinas contra Covid-19 no Telegram no Brasil. A partir de descritores associados ao tema da vacina, identificamos quatro grupos que abordaram a questão vacinal no período de dezembro de 2020 a fevereiro de 2022. Utilizando o método da Teoria Fundamentada, realizamos uma análise qualitativa dos principais argumentos apresentados para a contestação às vacinas nesses grupos. Os resultados revelam três linhas argumentativas utilizadas na contestação aos imunizantes contra Covid-19: (1) receios quanto à segurança e eficácia, (2) alegações de que existem interesses obscuros na gestão da pandemia e no desenvolvimento das vacinas e (3) defesa da liberdade e privacidade. A compreensão desses argumentos visa contribuir para o desenvolvimento de estratégias de contenção dos danos causados pela desinformação quanto à saúde individual e coletiva.

The article considers the issues of practical application of the approach on performance automation and scheduling of works on the maintenance of railway automatics and remote controlling devices in the process of planned preventive maintenance realization which includes the analysis of known ways to automate railway circuit inspections on shunt sensitivity and shunt effect performance control in the process of finding a moving unit on a rail circuit. At present, topical problem is the reduction of labor costs on the maintenance of dispersed objects of automatics and remote control which to solve for, we propose to use algorithms providing for technological situation identification and determination of the many of works which will be considered automatically as accomplished as well as the many of ones which will be needed to be accomplished in due time. The essence of the proposed approach to automation of being considered processes is in the following: if in the process of rail circuit functioning in regular mode, the situation, that’s analogous to the performance of work on shunt sensitivity testing (that’s stipulated by work operation technology), is realized, then work is considered to be accomplished at the presence of means of reliable control for the values of rail circuit parameters.

Published: March 2023

Trends in the development of computer-based interlocking systems are considered. The main emphasis when creating them is on achieving safety indicators no worse than those of relay analogues. The subsequent steps of improving the systems determined the directions of expansion of information support and automation of management. The main advantage of computer systems was the software implementation of a number of traditional functions that required the installation of additional relay equipment. The use of digital joints between the components of the system makes it possible to design a distributed structure of the computer-based interlocking systems on the basis of standard equipment, ensuring the rational use of computing power. Modern intelligent technologies as part of the tasks solved in the computer-based interlocking systems provide not only the choice of the best technological solutions for the organization of the station, but also allow you to exclude incorrect actions of personnel, free them from performing routine operations.

Authors: Kornev Dmitriy
Published: March 2023

In order to choose locomotive control algorithm when prognosing train motion rational mode in an exploitation by the methods of mathematical modeling, the calculation was performed of main technical and economic characteristics of the operation of diesel locomotive 2TE116U with a stock at the use of full power and at control, basing on the parameters of a mode map. The method basis represents train motion dynamic model on a railway section with a given profile. To verify the developed method, numerical studies were carried out in the wide range of changes of stock weights which not exceed the calculated weight. The obtained results have been compared with statistical data on the values of operational characteristics of train motion on Russia railways. It has been shown that train motion mode modelling at the use of locomotive full power gives a significant error at calculating technical speed, at the norm of train weight rate and fuel consumption and does not allow calculating locomotive control rational algorithm on optimization used criteria inclusive of operation conditions. At the choice of locomotive control rational algorithm, the necessity is substantiated for taking into account real conditions of train motion operation by batch or partially batch schedule which are reflected in mode map parameters.

In this study, it is aimed to examine the perceptions of the mathematics teacher candidates regarding the concept of fraction. 32 teacher candidates participated in the research carried out in the screening model. The word association test was used as a data collection tool and the obtained data were analyzed by content analysis method. According to the results of the analysis, it is seen that the perceptions of teacher candidates regarding the concept of fraction are mostly concentrated in the themes of meanings of fractions, operations in fractions, and representation of fractions. In addition, the themes of numbers, notation, and other mathematical topics in which it is used are other themes that emerged. It was seen that the teacher candidates expressed the quotient meaning at most, they did not mention the percent meaning. It was seen that they mostly expressed the addition operation in fractions and the type of compound fraction. As a result, it is seen that pre-service teachers' perceptions about the concept of fraction are limited. Pre-service teachers can be given a more comprehensive and relational education on the concept of fraction.

Improving the power generation performance and pollutant removal of photosynthetic microalgae microbial fuel cells (PMMFCs) is the key to their large-scale application. In this work, microalgae (Chlorella sp. QB-102) were used as a biocatalyst in the cathode, and foam nickel modified by graphene oxide with two degrees of oxidation was used as the electrode. The results showed that the maximum power density of PMMFCs with high oxidation degree graphene oxide modified electrode (NF-GO-H) reached 209.07 mW·m-2, which was 6 times that of PMMFCs with low oxidation degree graphene oxide modified electrode (NF-GO-L), indicating that the use of the NF-GO-H electrode can effectively improve the electrical properties of PMMFCs. Simultaneously, the NF-GO-H electrode can effectively remove Cd(II), with a capacity of 6.039 g·m-2, which is twice that of the NF-GO-L electrode. Moreover, through the synergistic electrochemical action of Chlorella sp. QB-102, a large number of hydroxyl groups can be generated to convert the adsorbed Cd(II) into a more stable Cd(OH)2 precipitate. The results of this work will further expand the application of PMMFCs in power generation and heavy metal removal.

This study aimed to find a significant difference between the learning outcomes of physics students taught through problem-based learning supported by a variety of visual media and those taught through conventional learning. This is to determine whether The method used in this study is quasi-experimental, using only a post-test control group design. The study population consisted of all 7th graders from public schools in South Sulawesi, and the sample was divided into two classes, an experimental class and a control class. The test vehicle for learning cognitive outcomes in the multiple-choice format of the extended material serves as a test vehicle. The sig values were obtained as a result of data analysis, i.e. based on the independent-samples t-test. (two-sided) is 0.000, which is less than the significance of 0.05, so Ho is rejected, and H1 is accepted. Thus, there is a significant difference between the physics learning outcomes of students taught through problem-based learning supported by a variety of visual media and the physics learning outcomes of students taught through conventional learning.

Tendons and ligaments injuries are frequent in sport horses and humans, representing a great therapeutic challenge. Tissue regeneration and function recovery are the paramount of tendon and ligament lesions management. Nowadays, several regenerative treatments are being developed, based on the use of stem cell and stem cell-based therapies. In the present study, the preparation of equine synovial membrane mesenchymal stem cells (eSM-MSCs) for clinical use - collection, transport, isolation, differentiation, characterization, and application is described. These cells are fibroblast-like and grow in clusters. They retain an osteogenic, chondrogenic and adipogenic differentiation potential. 16 clinical cases of tendonitis and desmitis, treated with allogenic eSM-MSCs and autologous serum are also presented, including their evaluation, treatment and follow-up. The use of autologous serum as a vehicle concern to a decreased immunogenic response after the administration of this combination and to its healing properties, due to the presence of growth factors and immunoglobulins. Most of the cases (14/16), healed in 30 days and presented a good outcome. Treatment of tendon and ligament lesions with the mixture of eSM-MSCs and autologous serum appears to be a promising clinical option for this category of lesions in equine patients.

The extracellular matrix (ECM) is earning an increasingly relevant role in many disease states and the process of aging. Analyzing these disease states is possible with GWAS and PheWAS methodology, and through our analysis, we aimed to explore the relationships between polymorphisms in the compendium of ECM genes (i.e., matrisome genes) in various disease states. A significant contribution on the part of the ECM polymorphisms is evident in many varying types of diseases, particularly those in the core matrisome genes. Our results confirm previous links to connective tissue disorders, but also unearth new and underexplored relationships with neurological, psychiatric, and age-related disease states. Upon analysis of drug indications for gene-disease relationships, we identified numerous targets that may be repurposed for age-related pathology. The identification of ECM polymorphisms and their contribution to disease plays an integral role in future therapeutic developments, drug repurposing, precision medicine, and personalized care.

Groundwater plays a crucial role in triggering and reactivating deep-seated landslides. However, classical hydrogeological investigations have limitations in their applicability to deep-seated landslides due to anisotropic and heterogeneous media[16]. The Huangtupo landslide in the Three Gorges reservoir area has garnered significant attention in China due to its large volume, complex geological structure, and high hazard potential. Recent monitoring data has shown notable deformation in the NO.1 Riverside Sliding Mass (HTP-1), one of the four parts of the Huangtupo landslide, making it the primary focus of landslide research. This study aimed to investigate the water sources in the HTP-1 landslide using environmental stable isotopes as tracers. The isotopic analysis results indicated that the groundwater in the landslide area (LGW) is a mixture of remote karst groundwater (KGW) from the adjacent up-slope and local precipitation (LP). The karst groundwater is a major contributor to the recharge of the landslide groundwater system, causing a high slope groundwater level that can easily exceed the critical level during heavy rainfall events. Furthermore, based on the differential distribution of the LP fraction of LGW at different locations, the groundwater in the landslide can be classified into three groups. Groundwater at the sliding rupture surface has the highest fractions of local precipitation, followed by the groundwater at the rear of the landslide. Combined with the monitoring data of groundwater level in boreholes during the rainy season, this indicates that fissures and fractures in the sliding rupture zone and at the back of the landslide are well connected, which could be a critical factor in the mass movement of the creeping slope.
