In this study, pre-harvest sprouting tolerance and some quality characteristics of some wheat landraces and modern varieties in Turkey were determined. In Eskişehir, Karaman and Samsun locations of Turkey, 126 genotypes were tested in the 2014-2015 growing seasons, and 48 genotypes were tested in the 2015-2016 and 2016-2017 growing seasons in two-replication experiments. Data regarding germination index, protein content, sedimentation volume and falling number of genotypes were observed. Physical properties of grain, the number of days to spike, and plant height were also investigated. The difference between genotypes was found to be statistically significant for all traits. We found the germination index of the genotypes varied between 0.19 and 0.70 for the 2015-2016 and 2016-2017 growing seasons, respectively. The average germination index value of red kernel genotypes is lower than white kernel genotypes. The landraces from Turkiye included in the research were taller and harvested lately. In comparison, modern genotypes are in the first place regarding sedimentation volume. The landraces had higher protein content but lower protein qualities than modern cultivars. The grain hardness of landraces was lower than that of modern cultivars in the three years. We found positive relationships between the germination index, grain filling time, thousand-grain weight, and grain color. Protein content, sedimentation volume, falling number, and grain hardness are negatively and significantly related to the germination index. The results showed that white kernel Clark's Cream and red kernel Karakılçık (1) genotypes could be used as gene sources for pre-harvest sprouting tolerance breeding in bread wheat.

Promoting Active Living and Sports as a Node for Wellbeing
Authors: Coccagna Maddalena
Published: April 2024

Physical inactivity is associated with various chronic diseases and early death. The pandemic and the economic crisis worsened mental disorders and the inability to cope with stress in healthy ways. People with disabilities may represent a barometer to quantify and assess equal access to sports. A multilevel strategy for the development of both social and physical environments must overcome the ‘medical’ meaning of health, dealing increasingly with a broader disability culture design. The promotion of an active lifestyle for all is a thread common to design products and services, with several national and international proposals to enable both a physical and service-based accessibility to wellness opportunities. A short field research conducted during the pandemic, starting from a visual campaign for athletes with Down syndrome, suggested a wide-ranging reflection on sports as amusement, on inclusive language and on equal participation in sports opportunities.

Authors: Belikov A.S. , Strezhekurov Yu.E. , Shalomov V.A. , Ragimov S.Yu.
Published: April 2024

Problem statement. The research demonstrates that existing methods for determining the distribution of thermal radiation intensity using nomograms and formulas contain significant errors. This is due to the adoption of a number of simplifications regarding numerous interdependent parameters, including the temperature inside furnaces, the size of openings and shafts, etc. As a result, there is a need for measurements of thermal radiation intensity at distances of 5−10 meters and beyond. The purpose of the article. The objective of the article is to propose a concept for a new experimental methodology to investigate the intensity of radiation exposure to workers at their workplaces. Simultaneously, in order to address the issues of thermal protection for workers, actual measurement data of thermal radiation levels are necessary for each workstation under real working conditions within the workspace. Conclusion. It is important to characterize the composition of the gas environment, as its impurities can distort the distribution of radiant energy through interference and diffraction effects, which need to be considered for microclimate optimization. The presence of dust particles complicates the straight-line heat transfer through scattering and scintillation of rays, requiring further improvement of models. Turbulence, impurities, and atmospheric heterogeneity are important factors that need to be further investigated and taken into account in heat transfer process modeling. Scintillation affects the quality of radiation transmission, necessitating further study of this phenomenon. Local atmospheric composition peculiarities require the development of models that consider these variations. The obtained experimental data will contribute to improving the accuracy of modeling and enhancing working conditions. Further refinement of measurement techniques is necessary for obtaining reliable information.

ISSUES OF DESIGNING INDUSTRIAL BUILDINGS CONSIDERING THE RISK OF LOCAL DESTRUCTION OF THEIR BEARING STRUCTURES
Authors: Ehorov Yev.A. , Radkevich A.V. , Kovtun K.A.
Published: April 2024

Problem statement. The present-day realities show that the design of buildings and structures with regard to possible local collapses of their bearing structures is becoming more and more realistic and thus an increasingly urgent challenge. The need to solve this issue is an important component in ensuring the safety of buildings and structures under operational and emergency loads. Local destruction is interpreted as a global result that can lead to the destruction of the entire frame or a significant part of it and cause loss of life. The peculiarity of calculations for progressive collapse of steel-framed buildings is that, unlike monolithic reinforced concrete, in a steel frame, the nodes of connection of elements are usually hinged, and this can lead to transformation of the structural scheme into a geometrically variable structural scheme. In this case, structural failure may occur not due to loss of material strength, but due to loss of load-bearing capacity of the structural connection joints. The purpose of the article is to analyse the main specific peculiarities occurring in the design (reinforcement) of industrial buildings with steel frames, considering the possibility of their local destruction. Conclusion. The article considers some problems that need to be solved during the designing or reconstructioning industrial buildings with a steel frame, the operation of which may be associated with some local destruction of the bearing structures. Prospective constructive ways of effectively solving these problems are presented.

Problem statement. Electromagnetic radiation is a combination of electric and magnetic radiation, the energy of which, when it affects a given material body, does not cause an ionisation process in it. Natural electromagnetic radiation not only guarantees the proper development of every living organism, but also affects the change of seasons and weather. Humans have disturbed the Earth's natural electromagnetic environment by including devices that emit electromagnetic energy in a wide range of frequencies. Artificial electromagnetic fields accompany us everywhere: at home, at work, on the road, and during leisure. The sanitary and hygienic state of the environment, including the electromagnetic situation in populated cities, is of great hygienic importance for ensuring proper living conditions for the population. The electromagnetic situation in cities and other settlements is created by a large number of radio and electrical equipment for economic, defence and other purposes. The purpose of the article. To conduct a systematic analysis of the impact of electromagnetic radiation from various types of electrical equipment on the environment. It is shown that electromagnetic radiation is dangerous both for the population as a whole, especially for children, and for personnel who operate powerful equipment - sources of electromagnetic radiation. Conclusion. Studies of electromagnetic radiation in the environment show that prolonged exposure to powerful electromagnetic fields can cause illness and even death. Therefore, rules for using artificial sources of electromagnetic radiation should be followed to minimise the damage to both human health and the environment. These rules are not so difficult to follow, but they are quite effective. And for labour protection and civil safety specialists, this knowledge will enable them to create safe working conditions in the workplace.

Penelitian ini bertujuan untuk mengetahui pengaruh penggunaan model pembelajaran STAD (Student Teams Achievement Division) berbantuan papan berpaku terhadap pemahaman siswa dan mengukur apakah terdapat peningkatan hasil belajar pada pelajaran matematika materi bangun datar. Penelitian ini menerapkan metode eksperimen kuantitatif desain penelitian One Group Pretest-Posttest. Nilai Sig yang didadapatkan dari uji homogenitas sebesar 0,120 yang artinya hasil tersebut adalah homogen. Kemudian pada uji t mendapatkan hasil bahwa nilai sign (2-tailed) sebesar 0,000 yang maknanya hasil tersebut lebih kecil dari nilai a yaitu 0,05 artinya nilai sign 0,000 < 0,05 maka Ho ditolak dan Ha diterima. Nilai sign pada uji normalitas Shapiro Wilk untuk pre-test dengan nilai signifikansinya 0,029 yang menunjukkan bahwa nilai sig 0,029>0,05 lebih besar yang berarti berdistribusi normal. Sedangkan untuk nilai post-test menunjukkan nilai signifikan 0,163 yang berarti data berdistribusi normal. Dengan itu dapat dikatakan bahwa model pembelejaran STAD (Student Teams Achievement Division) dengan berbantuan media pembelajaran papan berpaku berpengaruh dalam meningkatkan hasil belajar siswa kelas III SDN 1 Sukosono pada mata pelajaran matematika materi bangun datar.

This study looked into the types of comprehension-related reading issues that fourth-grade kids faced, the factors that influence reading difficulties, and the efforts made by these students, who were between the ages of 11 and 12, to overcome their reading difficulties. The study used a qualitative method to try to understand the reading challenges of English as a foreign language. Twenty-two fourth-graders served as the research subjects. Questionnaires, documentation, and interviews were employed in the data collection process. Qualitative data analysis was the method employed. The study's findings showed that 15 students had trouble reading and that they had trouble understanding English reading texts when they were given by their teachers. Fourth-grade pupils' difficulties reading English was caused by an internal factor: they were less motivated to learn English in class and had a smaller vocabulary. Regarding the external component, the school library contained no references to English-reading books. It is evident from the previous results that fourth-grade elementary school kids struggle with reading.
