In Situ Estimation of the Coefficient of Stress Source in the
Eulerian–Lagrangian Spray Atomization Model
Authors: Anumolu China Rama Lakshman , Dahale Ambarish R.
Published: July 2024

Liquid jet atomization is one of the key processes in many engineering
applications, such as IC engines, gas turbines, and the like, to name a few.
Simulating this process using a pure Eulerian or a pure Lagrangian framework has
its own drawbacks. The Eulerian–Lagrangian spray atomization (ELSA) modeling
seems like a viable alternative in such scenarios. ELSA simulations consist of
solving an additional transport equation for the surface area density (Σ) of the
issuing jet. In this study we have proposed a dynamic approach to compute the
turbulent timescale constant (α1), which appears in
the source of Σ-transport equation and is responsible for restoring the surface
area back to its equilibrium. The dynamic approach involves an analytical
computation of the turbulent timescale constant
(α1), thereby eliminating the need for ad hoc
adjustments to surface area values during computational fluid dynamics (CFD)
simulations. Unlike previous research which suggests using constant values in
the range (0, 1] for the α1-constant, we found that
these values can be as high as 60,000 for the engine combustion network (ECN)
spray-A nozzle conditions. The analytical closure procedure dampens the spurious
overshoots seen in the sigma-Y field and maintains values close to the
equilibrium conditions. The proposed approach is implemented in CONVERGE, a
commercially available CFD code and validated by comparing against available
experimental data.

In this paper we address the biography of a set of copper nails recovered in 1998 from a Late Iron Age structure located at the archaeological site of Puig de Sa Morisca (Mallorca, Spain). The archaeometric and typological analyses conducted on these nails allowed us to relate them to nautical technology, as well as to approach the origin of the raw materials and the production processes involved in their manufacture. The biographical information obtained from these studies has been crucial to address the extensive mobility of these copper nails through the Western Mediterranean during the Iron Age, as well as to approach their fluid nature and association with different communities of practice, assemblages and appropriation phenomena.

Despite extensive research and excavations across the central Balkans, Early Holocene sites have so far been documented only in the Iron Gates region – for which there are several possible explanations. Some scholars argue that the apparent lack of Mesolithic sites is due to inadequate research efforts in the region, while others suggest that the ecological conditions in the central Balkans during the Early Holocene may not have been favourable to the subsistence of hunter-gatherer communities. Contrary to previous beliefs, recent investigations of caves in eastern Serbia have revealed that humans inhabited the region during the Mesolithic. Traces of settlement of Mesolithic groups, dating back to the 7th millennium cal BC and employing comparable technology and economic practices to Mesolithic communities in other parts of the Balkan Peninsula, have been documented at the Pešterija Cave, situated south of Pirot in southeastern Serbia. The fact that the site is located relatively close to the oldest Neolithic sites in the Iron Gates and northwest Bulgaria, and is potentially contemporaneous with them, offers a completely new perspective on the transition from the Mesolithic to the Neolithic in this part of the Balkans.

In present time due to urbanization the plastic utilization in our daily life has been increased significantly as it being very useful and popular material. The only disadvantage is non-biodegradability. This study summarizes the work done by authors to use plastic as construction material in bricks. The recyclable properties of plastic waste can be utilized to recycle this waste and produce a new product having lesser negative impact on the environment. One of the options to recycle plastic waste is to form bricks of plastic by mixing plastics with sand which can be used to replace traditional bricks. Various authors performed comparative study with brick made up of other materials by using various testing method such as scratch test, apparent porosity, water absorption, apparent porosity test, soundness test, efflorescence test and analyzed that the further research on this field can enrich the strength, quality and durability of these masonry bricks. These bricks absorb very less water as compared to conventional bricks that is also very significant with the view of environmental sustainability.

Published: July 2024

For the hardened concrete, 150 mm × 150 mm × 150 mm cubic specimens and cylindrical specimens with a diameter of 100 mm and a height of 200 mm were tested to identify the compressive strength and splitting tensile strength of the concrete produced with waste glass. Next, a three-point bending test was carried out on samples with dimensions of 100 × 100 × 400 mm, and a span length of 300 mm to obtain the flexure behavior of different mixtures. According to the results obtained, a 20% substitution of WGP as cement can be considered the optimum dose. On the other hand, for concrete produced with combined WGP and crashed glass particles, mechanical properties increased up to a certain limit and then decreased owing to poor workability. Thus, 10% can be considered the optimum replacement level, as combined waste glass shows considerably higher strength and better workability properties. Furthermore, scanning electron microscope (SEM) analysis was performed to investigate the microstructure of the composition.

The unseen battle: Exploring the intersection between mental health struggles in elite athletes
Authors: Rhodes Oscar
Published: July 2024

El foco de la investigación sobre el desarrollo en la última década ha acentuado la naturaleza crítica de reconocer la salud mental de los atletas de élite. Profesionales e investigadores se han unido para reconocer la susceptibilidad de los deportistas de élite a los problemas de salud mental en un nivel similar al de la población general (Moesch et al., 2018; Poucher & Cairney, 2021). Se reconoce que los atletas de élite experimentan una amplia gama de trastornos como ansiedad, depresión, trastornos alimentarios y abuso de sustancias, que pueden verse influenciados por una serie de aspectos relacionados con su carrera atlética, su rendimiento y factores externos (Rice & Parker, 2016). ). La noción de "salud mental" se ha descrito de muchas maneras. Según la Organización Mundial de la Salud, la salud mental se define como “un estado de bienestar en el que cada individuo es consciente de su propio potencial, puede hacer frente a las tensiones normales de la vida, puede trabajar de forma productiva y fructífera y es capaz de hacer una contribución a su comunidad” (Organización Mundial de la Salud, 2014). Esta definición dada destaca que la salud mental va más allá de la ausencia de trastornos y enfatiza la capacidad de un individuo para lograr un bienestar óptimo. Además, la Asociación Estadounidense de Psiquiatría define los "trastornos mentales" como "un síndrome caracterizado por una alteración clínicamente significativa en la cognición, la regulación de las emociones o el comportamiento de un individuo que refleja una disfunción en los procesos psicológicos, biológicos o de desarrollo subyacentes al funcionamiento mental", incluidas las afecciones. como trastornos alimentarios, depresión y ansiedad (Asociación Estadounidense de Psiquiatría, 2013).

In modern conditions of modernization of state agricultural policy, the role of agricultural law, subject of legal regulation, protection of the interests of the entities of agricultural sector, and ensuring food security of the republic is increasing. The goal is to study the features of agricultural legal relations, identifying main problems associated with the application of legal liability. Analysis of the state, use of rules and norms of agricultural legislation and development of measures aimed to support, stimulate, and protect the rights of agricultural producers in Kazakhstan. The methods are based on materials from domestic and foreign scientists, scientific publications, and changes in legislative regulations. A comparative analysis and assessment of legal relations in agro-industrial production were used. Results - the state of affairs is considered and important issues of application of legal responsibility in the context of lawful actions and its features are identified. Various types of violations of legal obligations are analyzed: non-compliance with land use rules, sanitary and hygienic requirements, environmental standards - illegal use of pesticides, abuse of antibiotics in raising livestock, violation of environmental standards that can pollute water or damage the soil. Conclusions - the authors propose a number of effective measures to improve legal behavior in agricultural entities: strengthening control by the state law enforcement agencies, creating more effective punishment mechanisms, increasing awareness of participants in agricultural legal relations, which will prevent unfair practices and will promote conservation of natural resources and environment. Agricultural law presupposes land, property, labor, financial, and management relations in agriculture. This contributes to organizational, production and economic activities of agricultural production entities in accordance with the goals of entrepreneurship in agricultural sector.

The goal is to analyze production indicators of sugar beets and sugar for 1990-2023, to recommend measures to increase volume of sugar industry products. Methods - statistical, on the basis of which primary data on production of beet raw materials and sugar, its consumption per capita, export and import, and foreign trade turnover are collected. Results - the authors note that development of beet-sugar subcomplex is accompanied by stable decrease in quantity of this product, resulting in reduction in acreage and decrease in yield. The deterioration of parameters is due to high cost and low profitability of crop produced, outdated technical base, the use of lowquality seeds, problems with irrigation, and insufficient capacity of sugar factories. The current situation has a direct impact on the demand for sugar, which is met through imports and raw sugar obtained from processing. State measures aimed to increase sugar from domestic raw materials, set out in the Comprehensive Plan for the Development of Sugar Industry in the Republic of Kazakhstan for 2022-2026, were considered, in the framework of which it is provided to ensure the enterprises with unused agricultural land suitable for cultivating sugar beets within a radius of 150 kilometers to ensure their own raw materials taking into account the requests of the processors. Conclusions - the implementation of the set tasks will reduce sugar import dependence and saturate the domestic market with own products. At the same time, logistics issues, reducing cost of transporting finished products, and financing construction of railways need to be worked out.

Getting to post-post-truth
Authors: Legg Catherine
Published: July 2024

This piece ponders how teachers might best approach the issue of truth in the classroom, now that traditional models of truth-transmission have been problematised by what social epistemologist Steven Fuller calls ‘second-order awareness’—the apparent social construction of any given ‘truth-game’. Drawing on Charles Peirce’s original theorisation of the ‘community of inquiry’ at the birth of pragmatist philosophy, I argue that, as educators our best response to the recent ‘post-truth’ phenomenon is to pay less attention to our theories, in which we show up to truth-sceptics as experts, and more attention to our own epistemic practices, in which we show up to truth-sceptics as fellow persons. In any real-world encounter between persons, genuine listening and learning can offer practical proof that truth is not dead, notwithstanding the dire theoretical generalisations of sceptics, nihilists and relativists. I conclude by reflecting on some ways I’ve implemented these insights in developing a new first-year undergraduate Critical Thinking unit at my own university.
SOCIAL LISTENING ON THE INTERNET AS A COMPONENT FOR IMPROVING THE BUSINESS QUALITY AND COMPETITIVENESS OF MODERN COMPANIES
Authors:   Belgrade Business and Arts Academy of Applied Studies, Serbia, Bubanja Iva
Published: July 2024

In modern business conditions, when the company's online presence is no longer in question, companies use numerous techniques and methods to formulate online quality strategies to ensure their development and competitive business. One of these methods is social listening - an active process of monitoring, observing, interpreting and reacting to various user stimuli online. Being applied, currently, mainly on social networks, it allows for the recognition of the preferences of the audience and users, as well as to facilitate communication with them, but also to monitor the competitiveness and performance of the company on the market, the activities of competitors and identify new consumer trends. It can be beneficial for the users, as well, because it increases the sense of community, enables fair representation, raises the level of trust in the company, and increases participation in business policies. The use of the social listening method is moderate, even though its potential is great. The Social Media Listening Market size is estimated at USD 8.44 billion in 2024 and is expected to reach USD 16.19 billion in the next five years

n the conditions of a dynamic and competitive business environment, the concept of excellence is increasingly coming to the fore. Excellence refers to an organization's ability to consistently achieve exceptional results in all aspects of business, including efficiency, innovation, product/service quality, customer satisfaction and profitability. Organizations that achieve high excellence have a strong strategy, competent and talented employees, efficient processes, are permanently committed to continuous improvement, which enables them to be more competitive, more resistant to market changes and better able to satisfy the needs of their users. Strategic excellence provides a long-term vision, while operational excellence ensures that day-to-day activities contribute to that vision. Synergy between strategy and operations increases the overall competitiveness and sustainability of the organization. By integrating the concepts of organizational excellence, operational excellence and agility, organizations will be enabled to build a permanent capacity for constant changes and adaptation to a complex business environment. If business entities form operational excellence programs aware of their organizational resources, then the opportunity for structured development of adaptability is provided. The implementation and management of excellence programs affects the affirmation of the concept of agility in the entire organization as the development of opportunities that contribute to organizations by quickly adapting, responding to changes in the environment in both a reactive and a proactive manner
STANDARDS AND RECOMMENDATIONS WHEN TO INTRODUCE CERTAIN SPORTS FOR CHILDREN
Authors:   University of Belgrade, Faculty of Sport and Physical Education, Serbia, Bubanja Iva , Kasum Goran ,   University of Belgrade, Faculty of Sport and Physical Education, Serbia
Published: July 2024

ntroducing sports activities to children is a crucial factor for their holistic physical, mental, and social development. Well-structured physical exercise, particularly during the preschool years, fosters the development of motor skills, creative imagination, social abilities, and basic hygiene habits. Play, as the predominant activity during this period, induces qualitative changes in children's psyche and contributes to the acquisition of life experiences. This paper examines the optimal timing for introducing children to sports activities and offers recommendations for their multifaceted development prior to specialization in a specific sport. An effectively designed exercise program for young children should incorporate low-intensity exercises aimed at developing various physical capacities such as aerobic and anaerobic endurance, muscle endurance, speed, coordination, and flexibility. A systematic approach to exercise enables children to establish a robust foundation of basic skills and more easily adapt to the demands of training in later stages, thereby avoiding the pressure of early specialization. Furthermore, aligning sports activities with the child's biological age, while progressively increasing intensity and variety, enhances overall sports development and promotes a healthy lifestyle

Enhancing diet quality is a pivotal strategy in the battle against non-communicable diseases (NCDs) and a cornerstone of public health policy. The Nutri-Score, a front-of-pack (FOP) labeling system featuring five color-coded letters (A-E), serves as a beacon, guiding consumers towards healthier prepackaged foods. This system has a profound effect on consumer awareness, perception, comprehension, and purchasing behavior, potentially leading to a significant reduction in NCD prevalence. Despite their status as essential protein sources, processed meats have been associated with numerous diseases. By directing consumers towards healthier options through FOP labeling, such as the Nutri-Score, we can potentially alleviate the burden of diet-related diseases. This study classified processed meat products by Nutri-Score to identify nutritionally better options. Analyzing 387 products from major supermarket chains in Belgrade, Serbia, revealed most processed meats fell into classes D and E. Dried meat products and finely ground cooked sausages were ranked more favorably than dry-cured and dry fermented sausages. Significant improvements in Nutri- Score were seen in products with lower sodium chloride and saturated fats. Thus, some processed meats are nutritionally superior within their group, offering potential health benefits to those who choose them. Adopting FOP labeling systems like Nutri-Score is not just beneficial, but essential for steering consumers toward healthier dietary choices and supporting public health goals to reduce NCDs.

Belgian public authorities held liable for flawed climate policy: Klimaatzaak case
Authors: de Sadeleer Nicolas
Published: July 2024

The judgment handed down in the Klimaatzaak case by the French-speaking Court of First Instance of Brussels on 17 June 2021 was largely confirmed by the well-reasoned 160-page judgment of the Brussels Court of Appeal of 30 November 2023. This judgment raises fundamental issues relating to the judicial review of inaction by public authorities that leads to a failure to mitigate greenhouse gas (GHG) emissions. In reviewing the Belgian climate change policies in the light of the fundamental rights to life and private and family life and the general duty of care inherent in fault-based civil liability, the Court of Appeal narrowed the gap between Belgian GHG emission reduction targets and public mitigation measures. It follows that political rhetoric must be fleshed out into legal instruments that are properly designed to counter the impacts of climate change on life and privacy.

The achievement of sustainable development goals with the help of the implementation of a systematic approach to managing the resource potential of regions through sustainable development goals is one of the actual objectives in regional management. Mapping is known as an approach, which allows combining several data sources with different scaling. This study aims to develop regional resource provision map for creating sustainable development conditions. Multidisciplinary research is a valuable source of this research that allows to unit ESG criteria and their regional commitment through cartographic science tools. The methodology is presented in the form of a sequence of actions to draw up a resource supply map. Using the presented map of Western Kazakhstani region confirms the validity of the scientific and applied methodology. The research outcomes contain proven arguments for the further research based on the issues of constructing integrated resource provision maps for the Kazakhstani regions. Key cartography approaches make it possible to form recommendations for similar maps use in terms of decision-making based on interregional interaction, taking into account resource potential, consisting of natural, labor, financial, and infrastructural capabilities of the regions and environmental risk assessments. Developed recommendations were tested with the help of Microsoft Power BI and SuperMap (laboratory of “Geoinformation Cartography” of Kazakh National University named after al-Farabi Kazakh).

Shodhana, a crucial procedure in the pharmaceutical preparation of metals and minerals, aims to eliminate impurities and undesirable properties from raw materials, rendering them suitable for further processing. This study focuses on Samanya Shodhana of Pittala, a Mishra Loha, following the guidelines outlined in Rasa Ratna Samucchya. The process involves heating raw Pittala until red-hot and subsequently quenching it in Tila Taila, Takra, Gomutra, Kanji, and Kulatha Kwatha for seven iterations. Post-Shodhana, observations were made regarding the weight loss of Pittala, as well as pH and color changes in the respective liquid media. Results indicate a total weight loss of 7.0% in Pittala after Samanya Shodhana, suggesting effective impurity eradication.

Salah satu syarat untuk mendapatkan pengakuan pemerintah sebagai guru adalah memiliki kompetensi guru, yang meliputi: kompetensi profesi, kompetensi paedagogik, kompetensi kepribadian, dan kompetensi sosial. Perkembangan zaman mengharuskan setiap guru meningkatkan kompetensi guru yang dimilikinya.Tujuan penelitian ini untuk melihat apakah kompetensi kepribadian guru lebih baik setelah mengikuti pelatihan guru, dibandingkan sebelum pelatihan. Penelitian ini masuk kategori penelitian kuantitatif, dengan disain penelitian eksprimental, single group pre test-posttest design. Teknik analisis yang digunakan adalah teknik analisis komparasional menggunakan rumus t test dan uji satu arah. Lokasi penelitian di SMP Insan Cendikia Mandiri – Sidoarjo. Analisis data yang dilakukan memperlihatkan t hitung lebih besar dari t tabel, ini berarti bahwa hipotesis nihil yang menyatakan bahwa kompetensi kepribadian guru  tidak lebih baik dari kompetensi kepribadian guru sebelum pelatihan ditolak. Berarti yang diterima hipotesis alternatifnya yang menyatakan bahwa kompetensi kepribadian guru setelah pelatihan lebih baik dibandingkan dengan kompetensi kepribadian guru sebelum pelatihan.

Agarose-Resolvable SSR Markers Based on ddRADSeq in Chickpea
Authors: Sarı Duygu
Published: July 2024

Exploitation of genetic diversity is essential for sustainable crop production. Molecular markers have potential to reach these goals in more rapid and efficient manner. Here, we developed genomic SSR markers from chickpea with the use of ddRADSeq data. 1,396 SSR regions with an average of 530 SSR/Mb in the whole genome were successfully identified. Considering different types of repeats, dinucleotides were the most frequent type accounting for 62.03% of the total SSR regions identified, followed by trinucleotides (25.50%) and tetranucleotides (4.58%). The AT/TA motif was greatly characterized among dinucleotide repeats, and it was also the most common type in the chickpea genome accounting for 36.5% of the total SSR regions identified, followed by AG/GA (139) and TC/CT (135) among dinucleotide motifs. Considering their genomic distribution and simple visualization on agarose gels, we examined SSR regions of 10 bp and longer for identification of SSR markers. A total of 10 SSR markers were successfully designed and resulted in successful polymorphic bands among chickpea genotypes. Consequently, the results show that ddRADSeq is effective for marker development and these markers might be valuable for biodiversity studies, marker-assisted selection (MAS) and linkage map construction in chickpea.

Sertfikat pada dasarnya merupakan suatu bukti yang sah dalam membuktikan suatu keterangan fisik dan juga hukum yang ada di dalamnya. Namun apabila terdapat kesalahan dalam pembuatan sertifikat secara administrative, maka sertifikat dianggap tidak valid. Hal tersebut dapat menimbulkan pembatalan Sertifikat Hak Milik karena cacat hukum administratif dengan membatalkan Keputusan Kepala Kantor Pertanahan dilakukan dalam hal yaitu adanya cacat hukum dalam penerbitan sertifikat. Kasus yang terjadi akibat adanya pembatalan sertifikat terjadi di Desa Wongsorejo dari Penggungat (warga sipil) dan Tergugat Intervensi II (BPN), dimana terdapat lahan seluas 30m2 dengan kepemilikan yang tumpang tindih. Kondisi tersebut diajukan terhadap Pengadilan Negeri Banyuwangi. Namun pihak Penggugat tidak melanjutkan perkara tersebut di Pengadilan Negeri Banyuwangi melainkan melalukan pengajuan Gugatan ke Pengadilan Tata Usaha Negara di Surabaya untuk melakukan Gugatan Pembatalan Sertifikat Hak Milik. Sehingga dapat dikatan bahwa akibat hukum yang ditimbulkan antara putusan tingkat pertama dan banding karena tingkat pertama tidak bertanggung jawab dalam menerima, memeriksa, dan memutus perkara a quo sebab bukan kewenangan absolut. Perkara a quo ini menjadi perkara perbuatan melawan hukum sehingga yang berwenang dalam hal ini adalah Pengadilan Negeri Banyuwangi.
