Published: February 2023

In Suichang gold mine, the altered rock type gold deposits were cut by faults and joint fissures, leading to complex resource endowment characteristics, large changes in occurrence, a serious complex of ore vein branches and great difficulty in mining. In order to select a suitable mining method for such a difficult and complicated orebody, a multi-factor and multi-index comprehensive evaluation system involving benefits, costs, safety and other aspects was constructed by using the Pythagorean fuzzy sets and TOPSIS method. Taking Suichang gold mine as an example, the weighted aggregation evaluation matrix was constructed, the closeness index of the four mining schemes were 0.8436, 0.3370, 0.4296 and 0.4334, and the mechanized upward horizontal layering method was determined as the optimal scheme. This method overcame the fuzzy comparison of economic and technical indicators directly, but converted them into corresponding fuzzy numbers to obtain accurate closeness index for optimization. The application of this method not only ensured a safe, efficient and environment-friendly mining effect, but also provided a reference for the optimization of the mining scheme of the severely branched composite orebody.
Key Success Factors and Their Impact on the Performance of Construction Projects: Case in Qatar
Authors: Abal-Seqan Maryam Hussain , Pokharel Shaligram , Naji Khalid Kamal
Published: February 2023

The success of a construction project depends on different factors, the knowledge of the project managers, and the type of project being developed. In this paper, based on a review of the literature, 23 factors are identified as critical and they are grouped into top-management support, project manager’s skills, project team skills, and stakeholder-management knowledge. A framework with 23 hypotheses is developed to assess the relation between these factors and project performance. The analysis of the framework is conducted based on the responses obtained from a survey of 266 engineers working on construction projects in Qatar. The results show a positive relationship between critical success factors and project performance. The highest positive perception is shown for stakeholder engagement by the top management (mean = 5.589 ± 0.582) and the lowest positive perception for the need to predict stakeholder influence (mean = 3.939 ± 0.852). The analysis of the relative importance of these factors shows that the top-management support category is ranked highest for the success of a project. Although the perceptions are based on Qatar’s study, the success factors, their relationship with project success criteria, and project performance are global; therefore, the framework could be tailored and applied in different project contexts.

Published: February 2023

Emerging trends such as digitalization, globalization, and the COVID-19 pandemic are forcing higher education institutions to undergo constant organizational and technological changes and to introduce innovative pedagogical approaches suitable for teaching a new generation of students—the so-called digital natives. The goal of this paper is to engage in the ongoing debate in higher education about new teaching methods, i.e., game-based learning methods, which meet the needs of digital natives. They have grown up in a fast-paced, technology-driven society, which has affected how they absorb information, their ability to concentrate for extended periods, and their motivation and engagement in the learning process. Existing research suggests that implementing the game-based learning method can be very difficult and costly, as it often requires adapting the freely available game to the requirements of the particular course and additional investment in purchasing appropriate equipment. In this paper, we develop a comprehensive procedure for introducing a cost-effective game-based learning method in higher education, which includes thirteen steps to help lecturers introduce game-based activities straightforwardly into their teaching processes. In addition, we also present security, cultural, and quality assurance issues that need to be considered when implementing game-based learning in higher education.

Published: February 2023

This article offers a power quality (PQ) strategy to reduce light intensity flickers, voltage enhancements, and harmonics mitigation of the grid current in extensive networks of LED lighting at Cairo airport, Egypt. A transformerless unified power quality conditioner (TL-UPQC) with its controls is presented to address the majority of PQ issues in a network. The TL-UPQC comprises a dynamic voltage restorer (DVR) as a series compensator, which quickly maintains the load voltage when there is a voltage decrease, surge, or flickering in the network and an active power filter (APF) acts as a shunt compensator that reduces harmonic currents and injects reactive currents. The gain values of the PI controller are obtained using an extended bald eagle search (EBES) optimizer. In addition, a comparative study of three optimizers, namely, moth flame (MFO), cuckoo search (CSA), and salp swarm algorithm (SSA), is presented to test the performance of the PI controller and fast dynamic response. The results showed that the APF nearly obtained unity PF and that the harmonics produced as THD by LED light bulbs for current at the grid were abolished that becomes 3.29%. Additionally, the results verified that TL-UPQC could cancel voltage fluctuations at grid problems so that UPQC’s performance is successfully achieved to provide a flicker-free LED lighting network and this appeared clearly when used in LED lighting network at Cairo airport. MATLAB simulation has been employed to confirm the proposed TL-UPQC’s effectiveness.
Semilocal Convergence of a Multi-Step Parametric Family of Iterative Methods
Authors: Villalba Eva G. , Martínez Eulalia , Triguero-Navarro Paula
Published: February 2023

In this paper, we deal with a new family of iterative methods for approximating the solution of nonlinear systems for non-differentiable operators. The novelty of this family is that it is a m-step generalization of the Steffensen-type method by updating the divided difference operator in the first two steps but not in the following ones. This procedure allows us to increase both the order of convergence and the efficiency index with respect to that obtained in the family that updates divided differences only in the first step. We perform a semilocal convergence study that allows us to fix the convergence domain and uniqueness for real applied problems, where the existence of a solution is not known a priori. After this study, some numerical tests are developed to apply the semilocal convergence theoretical results obtained. Finally, mediating the dynamic planes generated by the different numerical methods that compose the family, we study the symmetry of the basins of attraction generated by each solution, the shape of these basins, and the convergence to each root of a polynomial function.

Chemically modified electrodes (CMEs) based on 2-phenyl-4-((4,6,8-trimethylazulen-1-yl)methylene)oxazol-5(4H)-one (M) were obtained by irreversible electrooxidation of M in millimolar solutions in 0.1 M tetrabutylammonium perchlorate (TBAP) in acetonitrile. These CMEs were characterized by a ferrocene redox probe, electrochemical impedance spectroscopy (EIS), X-ray photon spectroscopy (XPS), and scanning electron microscopy (SEM). The influence of the preparation conditions (charge and potential) was examined. The CMEs were finally used for the analysis of synthetic samples of heavy metal (HM) ions. The paper highlights the importance of potential and electropolymerization charge on the film properties, with accent on recognition of HMs, in order to identify the best conditions for their detection in water. The observed findings are relevant for further design and development of advanced materials based on azulenyl-phenyloxazolone for the analysis of HMs in water.

Authors: de Oliveira Jaqueline Mendes , dos Santos Debora Regina Lopes , Pinto Marcelo Alves
Published: February 2023

Hepatitis E virus (HEV) has emerged as a public health concern in Brazil. From the first identification and characterization of porcine and human HEV-3 strains in the 2000s, new HEV subtypes have been identified from animal, human, and environmental isolates. As new potential animal reservoirs have emerged, there is a need to compile evidence on the zoonotic dissemination of the virus in animal hosts and the environment. The increasing amount of seroprevalence data on sampled and randomly selected populations must be systematically retrieved, interpreted, and considered under the One Health concept. This review focused on HEV seroprevalence data in distinct animal reservoirs and human populations reported in the last two decades. Furthermore, the expertise with experimental infection models using non-human primates may provide new insights into HEV pathogenesis, prevention, and environmental surveillance.

Bunyamwera virus is the prototype of the Bunyamwera serogroup, which belongs to the order Bunyavirales of the Orthobunyavirus genus in the Peribunyaviridae family. Bunyamwera is a negative-sense RNA virus composed of three segments S, M, and L. Genetic recombination is possible between members of this order as it is already documented. Additionally, it can lead to pathogenic or host range improvement, if it occurs with viruses of public health and agricultural importance such as Rift Valley fever virus and Crimea–Congo hemorrhagic fever virus. Here, we characterize five African Orthobunyavirus viruses from different geographical regions. Our results suggest that the five newly characterized strains are identified as Bunyamwera virus strains. Furthermore, two of the five strains sequenced in this study are recombinant strains, as fragments of their segments are carried by Ngari and Bunyamwera strains. Further investigations are needed to understand the functional impact of these recombinations.

Non-human primates contribute to the spread of yellow fever virus (YFV) and the establishment of transmission cycles in endemic areas, such as Brazil. This study aims to investigate virological, histopathological and immunohistochemical findings in livers of squirrel monkeys (Saimiri spp.) infected with the YFV. Viremia occurred 1–30 days post infection (dpi) and the virus showed a predilection for the middle zone (Z2). The livers were jaundiced with subcapsular and hemorrhagic multifocal petechiae. Apoptosis, lytic and coagulative necrosis, steatosis and cellular edema were also observed. The immune response was characterized by the expression of S100, CD11b, CD57, CD4 and CD20; endothelial markers; stress and cell death; pro and anti-inflammatory cytokines, as well as Treg (IL-35) and IL-17 throughout the experimental period. Lesions during the severe phase of the disease were associated with excessive production of apoptotic pro-inflammatory cytokines, such as IFN-γ and TNF-α, released by inflammatory response cells (CD4+ and CD8+ T lymphocytes) and associated with high expression of molecules of adhesion in the inflammatory foci observed in Z2. Immunostaining of the local endothelium in vascular cells and the bile duct was intense, suggesting a fundamental role in liver damage and in the pathogenesis of the disease.
The Bovine Herpesvirus 1 Latency-Reactivation Cycle, a Chronic Problem in the Cattle Industry
Authors: Ostler Jeffery B. , Jones Clinton
Published: February 2023

Bovine alphaherpesvirus 1 (BoHV-1) is a persistent and recurring disease that affects cattle worldwide. It is a major contributor to bovine respiratory disease and reproductive failure in the US. A major complication of BoHV-1 arises from the lifelong latent infection established in the sensory ganglia of the peripheral nervous system following acute infection. Lifelong latency is marked by periodic reactivation from latency that leads to virus transmission and transient immunosuppression. Physiological and environmental stress, along with hormone fluctuations, can drive virus reactivation from latency, allowing the virus to spread rapidly. This review discusses the mechanisms of the latency/reactivation cycle, with particular emphasis on how different hormones directly regulate BoHV-1 gene expression and productive infection. Glucocorticoids, including the synthetic corticosteroid dexamethasone, are major effectors of the stress response. Stress directly regulates BoHV-1 gene expression through multiple pathways, including β-catenin dependent Wnt signaling, and the glucocorticoid receptor. Related type 1 nuclear hormone receptors, the androgen and progesterone receptors, also drive BoHV-1 gene expression and productive infection. These receptors form feed-forward transcription loops with the stress-induced Krüppel-like transcription factors KLF4 and KLF15. Understanding these molecular pathways is critical for developing novel therapeutics designed to block reactivation and reduce virus spread and disease.

Published: February 2023

African Swine Fever (ASF) is a highly contagious and lethal pig disease and poses a huge threat to the pig industry worldwide. ASF virus (ASFV) encodes more than 150 different proteins, but the biological properties of most viral proteins are still unknown. ASFV CP312R protein has been proven to be one of the most immunogenic proteins during ASFV infection in pigs; however, its specific epitopes have yet to be identified. In this study, we verified the immunogenicity of CP312R protein in the sera from attenuated ASFV-inoculated pigs. We generated seven anti-ASFV CP312R mouse monoclonal antibodies (mAbs) from mice immunized with recombinant CP312R protein (rCP312R). All seven mAbs are the IgG2b-Kappa isotype and specifically interacted with the CP312R protein expressed in various cells that were infected by ASFVs or transfected with plasmid CP312R. The epitope mapping was performed by using these characterized mAbs and the peptide scanning (Pepscan) method followed by Western blot. As a result, two antigenic determinant regions were identified: two of the seven mAbs recognized the 122KNEQGEEIYP131 amino acids, and the remaining five mAbs recognized the 78DEEVIRMNAE87 amino acids of the CP312R protein. These antigenic determinants of CP312R are conserved in different ASFV strains of seven genotypes. By using the characterized mAb, confocal microscopy observation revealed that the CP312R was mainly localized in the cytoplasm and, to some extent, in nuclei and on the nuclear membrane of infected host cells. In summary, our results benefit our understanding on the antigenic regions of ASFV CP312R and help to develop better serological diagnosis of ASF and vaccine research.

Published: February 2023

Coronavirus disease (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has been declared a pandemic. However, data on the poor or non-responders to SARS-CoV-2 vaccines in the general population are limited. The objective of this study was to comprehensively compare the immunological characteristics of poor or non-responders to SARS-CoV-2 vaccines in the 18–59-year group with those in the ≥60-year group using internationally recognized cut-off values. The main outcome was effective seroconversion characterized by an anti-SARS-CoV-2 spike IgG level of at least a four-fold increase from baseline. Profiling of naïve immune cells was analyzed prior to vaccination to demonstrate baseline immunity. The outcomes of effective seroconversion in patients aged 18–59 years with those in patients aged ≥60 years were compared. The quantitative level of anti-spike IgG was significantly lower in individuals aged ≥60 and men aged 18–59 years. There were 7.5% of poor or non-responders among the 18–59 years and 11.7% of poor or non-responders in the ≥60 years using a four-fold increase parameter. There were 37.0–58.1% with low lymphocyte count (<1000/mm3), 33.3–45.2% with low CD4 cell counts (<500/mm3), and 74.1–96.8% with low B cell counts (<100/mm3) in the non-seroconversion group. An individual with an anti-SARS-CoV-2 spike IgG titer below 50 BAU/mL might be considered a poor or non-responder between 14 and 90 days after the last vaccine dose. Booster vaccination or additional protective measures should be recommended to poor or non-responders as soon as possible to reduce disease severity and mortality.

COVID-19 is a major public health threat associated with the increased global burden of infectious diseases, mortality, and enormous economic loss to countries and communities. Safe and efficacious COVID-19 vaccines are crucial in halting the pandemic. We assessed the COVID-19 vaccine uptake and associated factors among community members from eight regions in Tanzania. The interviewer-administered questionnaire collected data. Multiple logistic regression models determined the factors associated with vaccine uptake. The median age of 3470 respondents was 37 years (interquartile range of 29–50 years) and 66% of them were females. Only 18% of them had received the COVID-19 vaccine, ranging from 8% in Dar es Salaam to 37% in Simiyu regions. A third (34%) of those vaccinated people did not know which vaccine they were given. Significantly higher rates of COVID-19 vaccine uptake were among the respondents aged 30+ years, males, and with a history of COVID-19 infection. Unfavorable perceptions about vaccine safety and efficacy lowered the rates of vaccine uptake. Setting-specific interventions and innovations are critical to improving vaccine uptake, given the observed differences between regions. Efforts are needed to increase vaccine uptake among women and younger people aged less than 30 years. Knowledge-based interventions should enhance the understanding of the available vaccines, benefits, target groups, and availability.

In the next twenty years, the scarcity of food shortage and drinking water will appear in Egypt due to the growth of industries and agriculture. This paper develops a conceptual design of the new technologies in the field of water–energy–food in new cities. Border lines are the internal relationship, external influence, and linkage system evaluation for WEF nexus. The major problems of using fossil energy in desalination are emissions and non-renewability, as well as the preference for dispersed freshwater production instead of concentrated output. The design of a desalination system that is integrated with renewable energies is critical these days. This type of system can also reduce the production of environmental pollutants due to reduced energy consumption and transfer of freshwater. GIS data from the United Nations have confirmed the existence of an underground reservoir in Wadi-Dara that can cultivate 1000 acres using smart farming techniques to reach a circular economy for an integrated solution between the water–energy nexus. The possibility of cultivating a hundred acres in Wadi-Dara on the Red Sea coast exists, through which about one million people could be settled. In this comprehensive review, we conducted a deep study in order to establish a sustainable integrated lifestyle in the Dara Valley region in terms of the availability of potable water, clean energy, and agriculture. Sustainable integrated solutions were conducted for seawater desalination using beach sand filtration wells as a pretreatment for seawater using renewable energy, e.g., wind energy (18% wind turbines), and photovoltaic panels (77% PV panels). Strategic food will be cultivated using smart farming that includes an open ponds cultivation system of microalgal cells to synthesis (5.0% of bio-fuel (. Aqua agriculture and aquaponics will cultivate marine culture and integrate mangrove, a shrimp aquaculture. A municipal waste water treatment is conceived for the irrigation of shrubby forests and landscapes. Mixotrophic cultures were explored to achieve a sustained ecological balance. Food, poultry and animal waste management, as well as a cooker factory, were included in the overall design. The environmental impact assessment (EIA) study shows a low risk due to anticipated net zero emissions, a 75% green city, and optimal waste recycling. This research assists in combining research efforts to address the challenging processes in nexus research and build resilient and sustainable water, energy, and food systems.

Published: February 2023

The effect of different CO2 concentrations and their subsequent light changes on the photosynthetic characteristics of Porphyra yezoensis are not well understood. The relationship between the availability of CO2 and light to physiological traits of the thalli could help understand the response and adaptation mechanisms of P. yezoensis to extreme weather changes. In this study, the photosynthetic response of P. yezoensis to light changes at different CO2 concentrations was determined. Under low light intensity, the high CO2 concentration promoted the relative growth rate (RGR) of P. yezoensis by 22.79% compared to that of ambient CO2 treatment. The net photosynthetic rate and phycoerythrin (PE) content under high CO2 were also significantly greater than those under ambient CO2 treatment at low light therapy. Under high light intensity, high CO2 exacerbated the inhibitory effect of light on the RGR of thalli. The net photosynthetic rate and PE content were significantly reduced by 12.53% and 14.06% at elevated CO2 concentration under a high light intensity, respectively. Furthermore, the net photosynthetic rate was significantly decreased when the light intensity was rapidly reduced, especially under simultaneously elevated CO2 concentrations. These findings indicate that elevated CO2 concentration increased the RGR and PE content at low light intensity of P. yezoensis. In addition, this study provides a theoretical basis for the response and adaptation mechanism of P. yezoensis to extreme weather changes.
The Assessment of the Quality and Quantity of Water Retained in Closed Granite Quarries with the View to Mitigate the Effects of Droughts in Agriculture
Authors: Jawecki Bartosz , Kowalczyk Tomasz
Published: February 2023

This paper presents the results of bathymetric measurements of quarry lakes located in inactive granite quarries (Poland, Lower Silesia, County Strzelin), which were used, among other reasons, to determine the surface area, depth, and volume of water retained in the analysed quarry lakes. The usability of water in quarry lakes for agricultural irrigation was also assessed, based on the FAO Guidelines and the PN-84/C-04635 standard. The average surface area of the analysed quarry lakes was 0.99 ha, the average depth was 6.0 m, and the maximum depth was 14.3 m. At the same time, the total volume of the retained water amounted to 307.8 thousand m3, which accounts for 10.6% of the retention capacity of water reservoirs situated in the catchment of the Oława River. The average values of water quality indicators were as follows: electrical conductivity—0.332 mS × cm−1; sodium adsorption ratio—0.56; total dissolved solids—212.4 mg/L; water pH—7.8; BOD5—2.4 mgO2/L. The mean concentrations of ions had the following values: nitrates—0.91 mgN-NO3−/L; sulphates—176.3 mg SO42−/L; chlorides—36.56 mg Cl−/L; sodium ions—14.8 mg Na+/L; calcium—41.3 mg Ca2+/L; magnesium—7.48 mg Mg2+/L; manganese—0.1 mg Mn/L; and iron—0.01 mg Fe/L. The concentrations of water quality indicators that were recorded for the analysed Strzelin quarry lakes were similar to those observed in natural lakes and uncharged water bodies. Water from the analysed quarry lakes met (with some minor limitations) the requirements that enable them to be used for agricultural irrigation. The volume of the water retained in the analysed quarry lakes constitutes an important element of the total balance of water retained in all the reservoirs, ponds, and all Strzelin quarry lakes situated in the catchment of the Oława River, accounting for 10.6% of the total volume of retained water. The article presents the innovative concept of the possibility of using water from quarry lakes in agriculture, based on their quantity and quality and the requirements for the purpose for which they will be used, e.g., for agricultural irrigation.
Prototype Experiments Assessing Arsenic and Iron Removal Efficiencies through Adsorption Using Natural Skye Sand
Authors: Khan Shahnoor Alam , Imteaz Monzur Alam
Published: February 2023

Based on earlier batch and column experimental results, it was established that Skye sand is suitable for removing arsenic from water through adsorption. As a real-size prototype may not always replicate results from batch and column experiments, this paper presents experimental results on arsenic removal through a prototype arsenic filter using the same Skye sand used in the batch and column experiments. As arsenic-contaminated water is often associated with a high concentration of iron, which causes blockage of the filter system, this study also investigates the removal of iron from the water through the same filter media. First, several physical properties of the Skye sand were established through XRF, XRD, SEM and EDX analyses. Then, a real-size prototype was made based on an earlier design of a similar filter made of iron oxide-coated sand (IOCS). It was found that the current filter is capable of removing arsenic consistently to a level below the detection limit (0.05 µg/L) for a considerable period (up to 150 bed volumes). Additionally, the same filter is capable of removing iron to a level below the WHO-acceptable limit (0.3 mg/L). Analytical calculation suggests that the current prototype filter with Skye sand can produce arsenic-free water continuously for 600 days (100 L per day) with a feed arsenic concentration of 500 µg/L.

Published: February 2023

The San Pedro del Pinatar I and II desalination plants in Spain were constructed near Posidonia oceanica meadows protected at the national and European level. The environmental impact statement for these plants stipulate that the brine discharge from the plant must not impact the meadows. To this end, a 4790 m submerged outfall was constructed to bypass the lower limit of the seagrass meadows, and a diffuser piece, along with an outfall pumping system, was installed at the end of the outfall. The objective of this paper is to evaluate the economic cost of the energy consumed for the brine discharge evacuation process necessary to comply with environmental requirements. The operating time and power consumption data were obtained from the plant’s monitoring system, while the energy cost was obtained from energy invoices. The computed results show that it is possible to minimize the environmental impacts of brine discharge on the marine environment of an SWRO plant with a low economic cost. The average energy consumption of the reject effluent pumping system ranged from 19.4 to 1239.3 thousand kWh per year, while the average annual energy cost was 49,329 €, which amounts to only 0.56% of the total energy cost for plant operation. The adoption of these measures provide a cost-effective means to meet environmental protection requirements and minimize the environmental impact associated with the discharged brine. As the demand for desalination operations increase, economically and scientifically viable technologies for mitigating environmental impacts are necessary for sustainability in this domain.
The Influence of Circular Economy and 4IR Technologies on the Climate–Water–Energy–Food Nexus and the SDGs
Authors: Hoosain Mohamed Sameer , Paul Babu Sena , Doorsamy Wesley , Ramakrishna Seeram
Published: February 2023

The United Nations Member States created a common roadmap for sustainability and development in 2015. The UN-SDGs are included in the 2030 Plan as an immediate call to action from all nations in the form of global partnerships. To date, a handful of countries have achieved substantial progress toward the targets. The climate–water–energy–food nexus is being advocated as a conceptual method for achieving sustainable development. According to research, frameworks for adopting nexus thinking have not been the best solution to clearly or sufficiently include thoughts on sustainability. Therefore, there is much room for other solutions; these are in the form of newer Fourth Industrial Revolution digital technologies, as well as transitioning from a linear economy to a circular economy. In this paper, we come to understand these two models and their linkages between climate, water, energy, and food; their application and challenges, and, finally, the effects on the UN-SDGs. It was found that both circular economy and newer Fourth Industrial Revolution digital technologies can positively support the nexus as well as directly address the UN-SDGs, specifically SDGs 7, 8, 9, 11, 12, and 13.
Ecological Impacts and Environmental Perceptions of Mining in Europe, 1200–1550: Preliminary Notes
Authors: Geltner Guy
Published: February 2023

Mines’ proliferation in Europe since the late twelfth century is widely known, but only recently have scholars begun to fathom the scale of the industry’s ecological impact, on the one hand, and its role in stimulating environmental thinking and action, on the other. Focusing on the extraction and processing of metal ores, this article begins by illustrating how the renascent sector reshaped different ecosystems, as traced by several paleo-scientific methods. It then turns to cultural-historical sources to propose that, rather than becoming passive, unwilling, or ignorant victims of a polluting industry, contemporaries criticized what they perceived as extraction’s harms and sought to reduce them, but also developed ways to justify their risks. Communities’ actions, which mingled with the materiality of mines and their surroundings, wrote a major chapter in Europe’s environmental history, one whose ongoing impact remains poorly understood.

Метою роботи був аналіз наукової літератури з метою вивчення стоматологічного статусу осіб, що займаються спортом вищих досягнень. Результати огляду свідчать про значну поширеність основних стоматологічних захворювань у спортсменів: відзначено високі показники індексу КПВ, досить часто діагностують некаріозні ураження зубів та захворювання пародонту. Проблема високої поширеності стоматологічних захворювань серед спортсменів залишаються не вирішеною, що робить її актуальною для глибшого вивчення, а також обумовлює необхідність розробки комплексних заходів у програмі профілактики основних стоматологічних захворювань у спортсменів. Дослідниками зазначено, що стоматологічна захворюваність у спортсменів, в тому числі і у дітей, що займаються спортом, не просто залишається на високому рівні, а й виходить на перше місце проти інших категорій населення, тому питання підвищення ефективності профілактики основних стоматологічних захворювань у дітей-спортсменів зберігають свою актуальність.

The results of research in the laboratory showed that the macroscopic symptoms of R. solani were initially brownish-white hyphae, then changed to light brown and when the culture was old it would have a dark brown color, while microscopically it was known that this fungus does not have spores, fungal hyphae are insulated, at first transparent white then turns brown, and the branches form elbows. The results of the research in the greenhouse were that the application of cow manure had a significant effect on the attack intensity of R. solani, namely the highest attack intensity was in the treatment without fertilizer (control) of 9.82% and the lowest attack intensity was in treatment 2.5 of 4 .75%, while the administration of antagonistic fungi did not significantly affect the intensity of R. solani attacks, as well as the interaction between the two treatments did not have a significant effect. Symptoms of attack from R. solani in the field are white mycelium, and brownish-gray spots on the leaf midribs close to the soil surface, these spots then expand to form blight, if the attack continues the base of the stem will rot and the leaf sheaths wither.

Approaches to the Algorithm of Analyzing the Results of Laboratory Testing of Micro- and
Macronutrient Content of Bakery Products: Part 2
Authors: Shcherbakov Grigory D. , Bessonov Vladimir V.
Published: February 2023

Introduction: Obtaining correct data on the chemical composition of food products is required for solving different problems, including those related to human health. It is important not only to organize the process of collecting sufficient data, but also to develop an analytical algorithm that considers different periods of data collection and types of foods.
Objective: To test and adjust the algorithm for obtaining statistically correct values of average concentrations and variability of the main micro- and macronutrients in bakery products.
Materials and methods: In order to test and then improve the algorithm, we used the results of laboratory testing of bakery products collected within the framework of the Federal Project on Public Health Strengthening in 2020–2021 by the laboratories of the Federal Service for Surveillance on Consumer Rights Protection and Human Wellbeing (Rospotrebnadzor).
Results: An increase in the sample size made it possible to identify new groups of bakery products. At the same time, the data of the sample combined over two years demonstrated the best convergence. The sodium content was determined as an additional clustering feature. The implementation of the algorithm on the pooled data enabled further reduction of the coefficient of variability.
Conclusion: Sequential processing of laboratory test results using the developed algorithm allowed us to update information on the chemical composition of bread currently sold by retailers and determine the presence of products that are critical in terms of their sodium content. It is of interest to expand capabilities of the algorithm in terms of automating the selection of priority indicators for clustering and, as a result, the possibility of processing similar data arrays.
Pravěké osídlení, půdy a zemědělské strategie

Příspěvek se zabývá a) vztahem pravěkého osídlení k půdám na území dnešních Čech, b) vztahem mezi obilninami pěstovanými v pravěku a vybranými parametry přírodního prostředí, zejména půdní produktivity, na území celé České republiky. Vztahy archeologických období a půdních typů se dají na úrovni makroregionu rozdělit do čtyř skupin, které v zásadě odpovídají vývoji pravěkého orebního zemědělství. Všechny zemědělské kultury přednostně využívaly oblasti kvalitních půd, ale byly schopné hospodařit i na půdách s nižší kvalitou. Silná vazba osídlení a nejlepších orebně zemědělských půd přestává platit v průběhu mladší fáze starší doby bronzové, ale opět se projevuje v závěru pravěku zejména v době stěhování národů. Nejdůležitější environmentální proměnnou, která ovlivňuje složení pravěkých souborů pěstovaných obilnin je kvalita půdy. To je nejvíce patrné na poměru pěstovaných pšenic a ječmene: s klesající půdní kvalitou stoupá podíl ječmene a klesá podíl pšenic. Ačkoliv ekologické nároky pravěkých obilnin nejsou známy, ukazuje se, že prospívaly za podobných podmínek jako dnešní odrůdy a strategie pravěkého zemědělství byla podobná dnešním neindustriálním zemědělským komunitám, to znamená dosažení stabilní úrody pomocí vhodného výběru optimálních plodin vzhledem k lokálním podmínkám.

Zaniklá středověká vesnice Ve spáleném u Vyžlovky (střední Čechy) se vyznačuje výraznými terénními relikty, které už přes sto let přitahují archeologický zájem. Její úplný a trvalý zánik spadal do průběhu 14. až počátku 15. století. Nacházela se u pramenné pánve nedaleko rozvodí a k zajištění dostatku vody sloužily v jejím areálu čtyři nádrže. Jedna z hrází těchto nádrží se vyznačuje výjimečnou morfologií, která vedla k úvahám o existenci jednoduchého mlýna. Zmíněnou hrází se zabýval geodeticko-topografický průzkum, geofyzikální měření a archeologická exkavace. Zvláštní pozornost je věnována zranitelnosti sídelních areálů závislých na málo vydatných vodních zdrojích.

Currículo Vivido no Cotidiano Escolar

Published: February 2023

O lazer é uma necessidade humana, impulsionada e, por vezes cerceada, por influências diversas, como a cultura, classe social, gênero, faixa etária, etnia, entre outros marcadores sociais. Porém, mesmo circunscrito por tantas coerções, o lazer existe e resiste de alguma forma. Se faz presente mesmo nas pequenas ações cotidianas que se desviam das obrigatoriedades por alguns momentos, bem como nos tempos alargados, conquistados após inúmeras lutas sociais na história. Com essa premissa, a presente pesquisa teve como objetivo geral identificar os possíveis lugares do fenômeno do lazer na escola do ensino fundamental. Para isso elencamos os seguintes objetivos específicos: (1) Investigar metodologias de pesquisa capazes de aproximar pesquisadora e grupo co-pesquisador, (2) compreender com as crianças constituintes do grupo-pesquisador os possíveis lugares do lazer na escola e (3) distinguir no cotidiano escolar as experiências de lazer discentes. Para isso utilizamos de abordagem qualitativa. Na primeira fase da pesquisa a metodologia sociopoética se fez presente por meio da pesquisa mediada por aparelhos tecnológicos, baseada em Conversas individuais e em grupo via aplicativo de mensagens (WhatsApp©), Rodas de Conversa via ferramenta de videoconferência (Google Meet©), bem como produções artísticas, dentre elas, desenhos e vídeos. Na segunda fase da pesquisa realizamos a observação participante na escola que acolheu a pesquisa, registradas em Diário de Campo. A partir da triangulação dos dados de ambas as fases da pesquisa identificamos alguns lugares de lazer na escola, foram eles: a resistência, a articulação, a fruição, a recompensa, a mistura de usos, a quebra de regras, a raridade, as oportunidades, a fluidez, a marginalização e a vertigem. Dessa forma, percebemos é possível distinguir que um dos lugares do lugar do lazer na escola está na clandestinidade. Velado, este se mantém atento às oportunidades e delas se aproveita. Metaforiza as regras para que funcionem por seus próprios quadros de referência, se efetiva em meio às minúcias, pequenas brechas encontradas ou cunhadas no cotidiano da escola. E assim, calcula formas de proceder, articulando-se à vivência escolar cotidiana, infiltrado e presente.
