Створення здорових і безпечних умов праці – основне завдання роботодавця. Під час виконання робіт із ремонту та технічного обслуговування технологічного обладнання встановлено, що основною причиною нещасних випадків під час проведення ремонтних робіт і обслуговування технологічного обладнання є недосконалість організації процедури блокування небезпечних енергій, наслідком чого є помилкова подача небезпечної енергії на установку, де працюють люди. Для профілактики виробничого травматизму на підприємствах металургії постає необхідність перегляду та модернізації встановленої на підприємствах процедури контролю подачі небезпечної енергії під час виконання ремонтних робіт завдяки періодичному аудиту стану реалізації системи блокування, маркування та перевірки (БМП) відповідно до кращих світових практик. Як показав аналіз використання системи аудиту системи блокування, маркування та перевірки на підприємствах металургійної галузі, вона орієнтована на збір даних щодо використання системи блокування, маркування та перевірки, обліку заходів, які були запропоновані за результатами аудиту. За результатами досліджень обґрунтовано напрям удосконалення аудиту системи блокування, маркування та перевірки.

У роботі розглянуті дослідження в галузі мехатроніки, спрямовані на створення засобів робототехніки, що базуються на технічних системах і комплексах. Основним напрямом застосування таких систем залишається промисловість, зокрема машинобудування та приладобудування. У роботі був проведений аналіз і розроблена класифікація технологічних комплексів із використанням роботів. Також було проаналізовано склад алгоритмічного етапу розроблення для визначення алгоритмів функціонування всього комплексу та його складників, а також вимог до пристроїв керування, каналів зв’язку та допоміжного обладнання. Визначено, що в алгоритмічному розробленні технологічних комплексів актуальним є забезпечення дотримання вимог до їхньої надійності. У роботі розроблено функціональну схему організації управління технологічним комплексом, завершальним етапом процесу проєктування технологічного комплексу є його технічна реалізація. Цей етап включає, зокрема, розроблення або вибір промислових роботів, пристроїв їх керування, технологічного обладнання, транспортних шляхів і видів транспорту, каналів зв’язку, засобів захисту інформації на основі вимог, визначених на попередніх етапах проєктування. За результатами роботизації технологічних комплексів у виробництві, що діє, установлено, що завдання комплексної автоматизації наявного виробництва мають суттєві особливості, які ускладнюють їх вирішення, порівняно зі створенням нових технологічних комплексів. Для вирішенні завдання керування всіма комплексами принципове значення має вантажопідйомність промислових роботів та іншого робототехнічного обладнання, оскільки вона в основному визначає їхні розміри, отже, можливість розміщення на робочих місцях замість вивільнюваних працівників. Установлено, що поруч із промисловими роботами для зазначених вище цілей можливе широке застосування збалансованих маніпуляторів із ручним керуванням, які дозволяють суттєво полегшити умови праці, підвищити продуктивність праці, тим самим зменшити чисельність працівників.

Published: September 2024

El propósito de este estudio fue determinar los efectos de señalar o no demoras de reforzamiento de 2 ó 6 s en combinación con intervalos entre ensayos (IEE) de 15 o 45 s sobre el porcentaje de respuestas correctas en una tarea de discriminación condicional. Se formaron 4 grupos de ratas. Para los cuatro grupos se señaló la demora durante la fase de adquisición de la discriminación. En una segunda fase se eliminó la señal, mientras que en una fase de redeterminación se volvió a presentar la señal. Se encontró un mayor porcentaje de respuestas correctas cuando la demora de reforzamiento fue de 2 s y cuando el IEE fue de 45 s. La eliminación de la señal resultó en un decremento de la precisión en todos los grupos, siendo menor en aquellos con un IEE de 45 s. Los resultados se contrastan con los hallazgos reportados en el área.
Longitudinal associations of experiential and reflective dimensions of meaning in life with psychopathological symptoms
Authors: Anoschin Albert , Zürn Michael K. , Remmers Carina
Published: September 2024

Background

Rather than being rooted in deliberate reflection, the experience of meaning has been shown to evolve from intuitive processes (Heintzelman & King, 2013b, https://doi.org/10.1007/978-94-007-6527-6_7). Accordingly, experiential and reflective dimensions of meaning in life can be distinguished (Hill et al., 2019, https://doi.org/10.1080/09515070.2018.1434483). In this preregistered study, we explored how these dimensions are longitudinally associated with psychopathological symptoms. We expected that experiencing more meaning would predict fewer depressive symptoms and fewer personality functioning impairments six months later, whereas reflecting about meaning would predict more psychopathological symptoms.

Method

A German-speaking sample of N = 388 completed self-report measures assessing meaning in life, depression, and personality functioning at baseline and six months later.

Results

Controlling for depression at baseline, elevated levels of experiencing meaning in life predicted a decrease in depressive symptoms. Experiencing meaning did not predict personality functioning impairments six months later. However, exploratory analyses with a larger sample tentatively showed that experiencing meaning in life predicted less impairments in personality functioning. Evidence supporting the hypothesized association between reflection and future depression as well as future personality functioning impairments was discerned through exploratory analyses. Generalizability of results to clinical care settings is limited due to the studied non-clinical sample. No causal conclusions can be drawn from the data because the study employed an observational design with two assessment points.

Conclusion

Experiencing meaning in life emerged as a potential protective factor against future psychopathological symptoms, whereas exploratory analyses pointed to an opposite relationship for reflection about meaning in life. Results are discussed with regard to clinical implications and directions for future research.
mpmsim: An R package for simulating matrix population models
Authors: Jones Owen
Published: September 2024

1. Matrix population models (MPMs) are widely used in ecology and evolution to explore population dynamics, including assessing management impacts and extinction risk. In comparative studies, MPMs can be used to test life history theory or investigate macro-evolutionary patterns in demographic traits. 2. Simulated MPMs can help researchers explore the effects of life cycle structure, vital rate trajectories, and uncertainty in transition rates due to sampling error. They are also valuable teaching tools. 3. The mpmsim R package enables users to simulate random or semi-random Lefkovitch and Leslie MPMs based on life history archetypes or mortality and fecundity patterns. It also allows the exploration of sampling error effects and uses parametric bootstrapping to calculate confidence intervals for matrix-derived estimates. 4. mpmsim provides a convenient toolset for addressing questions about MPMs and life history, with full documentation and user-friendly vignettes.

Published: September 2024

Investigation of this topic is relevant in light of the significant increase in the frequency and scale of cyber-attacks that affect various industries and organisations. The purpose of this study is to analyse existing data protection methods at the Front-end, which are able to effectively protect the confidentiality of user data in the face of modern cyber threats. Among the methods used, the analytical method, synthesis, classification, statistical and other methods should be noted. The study identified serious risks associated with storing confidential data on the client side. In particular, the use of cookies and local storage turned out to be vulnerable points that pose potential threats to data security. An analysis of existing web applications revealed the presence of cross-site scripting (XSS) vulnerabilities, which became a route for the introduction of malicious scripts. It was revealed that the generation and use of unique cross-site request forgery (CSRF) tokens for each request play a key role in preventing cross-site request forgery. The implementation of Governance as Code (GaC) technology has demonstrated potential for automating compliance with established architectural and security standards, thereby reinforcing front-end defenses against cyber threats. The findings emphasise the importance of educating end users on the basic principles of network security. The study highlights the importance of developers’ active involvement in Front-end security. Thus, a comprehensive overview of the Front-end security architecture with a focus on protecting user data and ensuring privacy is provided. The practical significance of the study lies in the provision of specific recommendations and practical solutions to improve Front-end security in web applications and represents a valuable set of tools and approaches that can be applied by developers and engineers to strengthen the security of web applications. The addition of Governance as Code technology introduces an innovative layer of automated security enforcement that is particularly suited to addressing emerging cybersecurity challenges in real-time.
Design of the endoskeleton of a biocontrolled hand prosthesis

Published: September 2024

The article analyzes the constructions of biocontrolled prostheses that are common today on the market of prosthetic equipment, in particular the i-Limb, «Michelangelo hand» and Bebionic prostheses. It is shown that these constructions use hollow shell models of the phalanges of the fingers and the palm, which together form the exoskeleton of the prosthesis construction. This type of design is characterized by the complexity of manufacturing, and accordingly, the cost, and the irrational use of volume, since traction elements, gear elements or other elements are placed inside these hollow elements, which ensure the transmission of forces when performing bending movements of such fingers. The article proposes the use of the endoskeleton as a support base for fixing electric drives and control elements. At the same time, the structure is a group of hingedly connected elements and rods for the transmission of forces, in which simultaneous bending is ensured in all hinged joints, and the form of the performed movements is close to natural. At the same time, the volume of the finger elements is more rationally used in the proposed design, as it becomes possible to fix out external nozzles of elastomeric materials on the structure rod, which will repeat the shape of real fingers, will be soft for reliable holding of objects when performing grip movements. At the same time, it becomes possible to install sensors in such elastomeric elements to provide tactile sensations. As a result of the research, 3-D models of all prosthesis endoskeleton elements were developed and they were manufactured by 3-D printing. At the prototyping stage, bipolar stepper motors controlled by the Arduino Uno module were used as electric drives to evaluate the trajectories of the performed movements. It is shown that it becomes possible to increase the functionality due to the installation of sensors to provide tactile sensations It was established that the number of performed movements is practically the same as that of analogues, and the cost of the proposed design is much lower. At the same time, reliability is higher due to the use of a much smaller number of structural elements and their connections.
Research of the mathematical model of the tribosystem head rod-bushing of the traction organ of rod transporters
Authors: Dovbush Taras , Khomyk Nadia , Dovbush Anatoliy
Published: September 2024

The service life and durability of transport and assembly machines depends on structural, technological and operational factors. The wear and tear of parts and working bodies causes a violation of the level and stability of the fulfillment of technical requirements, a decrease in reliability and efficiency, and a reduction in the service life of machines. Any technical means, in particular agricultural ones, can be considered as a system of serially or parallel connected units, aggregates and elements operating under conditions of load dynamics and wear and tear. The failure of one of the elements of the friction unit leads to the loss of its performance. The result is a complete or partial loss of machine performance as a whole. The most rational way to increase the durability of machines is to reduce wear and tear. This can be achieved by developing methods for evaluating the wear of friction parts. The paper proposes a model for evaluating the wear of the rod head-sleeve conjugation of the conveyor traction body of the rod conveyor of root-harvesting machines. The developed model of the tribosystem provides an opportunity to determine the estimated service life of the bars, that is, the conveyor as a whole. The geometric, kinematic and power factors affecting the wear processes of the tribo coupling under study were analyzed. The assessment of the maximum contact stresses of the contacting surfaces of the tribocoupler was performed to prevent premature destruction. The evaluation was performed in the initial stage of the transport machine, when the contact areas are minimal. The average statistical stresses arising in the contact zones, at which the wear process reaches critical values, are determined. Such studies make it possible to unify the dependence for determining the service life of a rod conveyor based on a sleeve-roller chain. Taking into account that the contact stresses depend on the force and geometric parameters, it is advisable to use the obtained mathematical model for the design of the rod-sleeve connection structures to ensure the specified service life of the mechanism.
Human Resource Practices and Employee Retention: The Moderating Effect of Job Engagement
Authors: Yamoah Emmanuel Erastus , Yeboah Isaac Asante , Nyala Dorcas Nyulnye
Published: September 2024

This study investigates the relationship between human resource management (HRM) practices and employee retention in Ghana's Information and Communication Technology (ICT) sector, emphasizing the moderating role of job engagement. High turnover rates in this sector pose significant challenges, prompting the need for effective HRM strategies. The study identifies key HR practices, including compensation and training and development, as critical drivers of employee retention. It employs a quantitative approach, utilizing structural equation modeling (SEM) to analyze data from employees at the National Information Technology Agency (NITA). The findings reveal that both compensation and training significantly influence retention rates, with job engagement enhancing these effects. Specifically, engaged employees are more likely to remain with their organizations when they perceive fair compensation and effective training programs. However, the study uncovers a complex interaction where high job engagement may negatively moderate the relationship between training and retention, suggesting potential role overload or misalignment with employee needs. The research contributes to existing literature by integrating theories such as Equity Theory, Human Capital Theory, and Job Demands-Resources Theory to explain how HRM practices can be optimized for better retention outcomes. The implications extend to HR managers who are encouraged to develop equitable compensation structures and comprehensive training initiatives while fostering an engaging work environment. Limitations include the study's cross-sectional design and focus on a single organization, which may affect generalizability. Future research is recommended to explore longitudinal effects and additional variables influencing employee retention across diverse sectors.

Authors: Mattos Amanda do Prado , Boff Mari Ines Carissimi , Boff Pedro
Published: September 2024

This work aimed to evaluate the impact of dynamized high dilutions on rust development and yield fig plants. Studies were conducted in the field. The experimental design was in split-plot, with five replications. The treatments were Belladonna, Thuya occidentalis, and nosode of fig-rusted leaves, all at 30 CH – centesimal Hahnemannian dilution order. Distilled water was used as the control. The cultivars used were Roxo de Valinhos and Branco Rosa Lages. Spray applications were performed every 15 days. The incidence and severity of rust Cerotelium fici were evaluated every seven days. The number of fruits per plant was counted. Belladonna reduced the severity of rust. Thuya occidentalis and nosode improved leave persistence. Dynamized high dilutions are a potential strategy to improve the tolerance of fig plants to drought and rust.
Characterization of the edaphic quality in agroecosystems managed by peasants families of Pirané, Formosa, Argentina
Authors: Mangione Stella Maris , Salazar Centeno Dennis José , Trejo Nora , Galián Liliana Rosa
Published: September 2024

Soil quality can be inherited and dynamic. The first refers to soil formation processes and the latter to anthropogenic effects. The objective of this research was to characterize the edaphic quality of four peasants agroecosystems through physical, chemical, biological indicators and anthropogenic influence, as a baseline for monitoring in soil quality and for the implementation of technologies, practices and biodiversity management alternatives for the promotion of the agroecological paradigm. The theoretical-methodological perspective was mixed. The strongly acidic pH of AAG soil is the limiting chemical factor, while moderate salinity in TAG and TAD restricts plant nutrition. In the four agroecosystems, CFU g-1 of soil were quantified. They belonged to diazotrophic microorganisms, NH4+ and NO2 oxidizers, P solubilizers, cellulolytic fungi and total fungi, whose populations are very sensitive to edaphoclimatic conditions and anthropogenic effects, but contribute to natural biofertilization, natural phytostimulation, biological control and natural bioremediation, which promotes the suppressive effect of these soils.

A pesquisa verificou de que forma a implementação de ações de promoção da Segurança Alimentar e Nutricional, executadas no Distrito Federal, influenciaram o empoderamento de agricultoras em dois pré-assentamentos rurais, a saber: Chapadinha e Pequeno William. Foram realizadas entrevistas e o levantamento de documentos em órgãos responsáveis por operacionalizar as políticas públicas. Observou-se o impacto das ações e das políticas analisadas sobre o empoderamento das entrevistadas. A pesquisa mostrou a dificuldade de acesso à terra em ambas as comunidades estudadas, sendo que o assentamento Chapadinha ainda está no processo de oficialização, logo, tem restrições para realizar investimentos de infraestrutura produtiva e social. Também foi observada a existência da insegurança hídrica, especialmente no Pequeno William, o que limita a produção de alimentos pelas agricultoras e as impede de acessar programas de compras institucionais. A interação entre água, energia e alimento ficou evidenciada no caso estudado, visto que o sucesso das políticas de Segurança Alimentar e Nutricional depende igualmente das seguranças hídrica e energética, conforme abordagem Nexus.

Published: September 2024

O crescimento significativo de iniciativas em redes alimentares alternativas tem gerado novas relações de produção, distribuição e consumo. Com a pandemia da Covid-19, evidenciou-se a urgência da transformação dos sistemas agroalimentares em prol de práticas mais sustentáveis. O presente artigo apresenta uma análise das mudanças qualitativas na relação de proximidade e nos valores compartilhados entre agricultores e consumidores em redes de alimentos orgânicos da cidade de São Paulo. Foram conduzidas revisão de literatura e pesquisa de campo, a qual incluiu entrevistas semiestruturadas com agricultores de uma cooperativa de orgânicos e questionários estruturados com duas redes de consumo responsável. A comercialização dos orgânicos foi impactada pontualmente nos meses mais críticos da Covid-19, entretanto, esse período trouxe inovações nas formas de escoar a produção e de estar em contato com os consumidores. Se por um lado a pandemia limitou a proximidade física nas redes alimentares alternativas, por outro, gerou uma maior conscientização sobre a importância da alimentação saudável, e sua inter-relação com a agroecologia e a saúde humana, animal e ambiental.

Celebremos os 20 anos da ABA-Agroecologia como semente plantada em solo fértil resultando em árvore frondosa, cuja copa imensamente ramificada emerge de um tronco robusto assentado e alimentado por raízes sadias.
Há que se destacar o fértil período político que enseja a fundação da ABA-Agroecologia (2004) e da criação da Revista Brasileira de Agroecologia (2006), na esteira de importantes eventos tais como o II Congresso Brasileiro de Agroecologia, V Seminário Internacional sobre Agroecologia e VI Seminário Estadual sobre Agroecologia. Esta série de eventos evidenciam contextos em que os princípios da Agroecologia foram emergindo e constituindo-se num processo epistêmico para o qual as políticas públicas foram sendo convocadas a abrir caminhos, tanto no âmbito da academia, da pesquisa, da extensão, dos movimentos sociais, agricultores familiares, consumidores, etc. Um contexto construído num movimento “de baixo para cima”, um contexto de mobilização social. O mais importante como desafio futuro da ABA-Agroecologia está em abrir espaço para o fundamental debate sobre a episteme agroecológica, promovendo a ideia de que não se tem um modelo pronto e acabado da Agroecologia.

Purpose: To evaluate the incidence and identify risk factors for acute kidney injury (AKI) within the first 15 days of life in very low birth weight (VLBW) infants in a neonatal intensive care unit. Additionally, this study will examine whether AKI correlates with increased mortality rate in this population.Methods: A prospective analysis was conducted on VLBW infants admitted to the neonatal intensive care unit from March 2017 to July 2021, diagnosing AKI based on the neonatal modified Kidney Disease: Improving Global Outcomes criteria. Neonates who died before obtaining consent, had complex malformation, or only one serum creatinine measurement were excluded.Results: Out of 121 admitted VLBW infants, 97 were analyzed, with 20 (20.6%; 95% confidence interval, 12.6–28.7) diagnosed with AKI. Among these, 50% had creatinine abnormalities, 30% had urinary output changes, and 20% had both. Severe AKI (stage 2 or 3) was observed in 30% of cases, none required dialysis. AKI was associated with higher SNAPPE-II (Score for Neonatal Acute Physiology with Perinatal Extension-II) scores, more frequent severe intraventricular hemorrhage, and an increased mortality rate (35%). Multivariate analysis identified AKI as an independent risk factor for mortality, with a 9.72-fold increased risk (95% confidence interval, 2.53–37.4; P<0.01), and a shorter time to death.Conclusions: Our findings underscore a significant incidence of AKI among VLBW infants, along with its strong association with increased mortality. These results highlight the critical need for thorough assessment of both serum creatinine and urinary output when diagnosing AKI in this vulnerable population.

Published: September 2024

This study examines the integration of Islamic Religious Education (PAI) subjects with entrepreneurship (PKWU) and economics. The problem in this study is the rise of dichotomy of knowledge in public education which separates religious knowledge from general science. This causes misunderstandings and fragmentation of students' knowledge. This research is a field research using a qualitative approach. Data collection was carried out by observation, structured interviews and documentation. Data analysis used the Miles and Huberman analysis technique which consisted of three stages namely; data reduction, presentation, and verification. The results of the study stated that there was strong integration between Islamic Religious Education (PAI) subjects and entrepreneurship and economics craft subjects. This can be seen from the internalization of the values of Islamic religious education in economics subjects and entrepreneurial crafts, especially in the material principles and economic practices in Islam. This can be seen from the learning process and products produced by students in craft and entrepreneurship subjects as well as the economic principles taught. In addition, there are also marketing day activities and traditional food bazaars which are held according to Islamic law.

Dalam konteks pendidikan, khususnya di Sekolah Menengah Atas (SMA) seperti di SMA 2 Sidrap, tindak tutur ekspresif memainkan peran penting dalam membangun hubungan interpersonal antara siswa dan guru. Studi mengenai tindak tutur ekspresif di lingkungan sekolah memberikan wawasan tentang bagaimana siswa mengekspresikan emosi mereka dalam berbagai situasi formal maupun informal. Tuturan merupakan kegiatan komunikasi sehari-hari yang melibatkan penerimaan dan pengiriman makna atau informasi. Tuturan, yang dalam konteks pragmatik dianggap sebagai hasil dari suatu tindakan verbal, memiliki sifat psikologis yang bergantung pada kemampuan berbahasa penutur dalam menghadapi situasi tertentu, dikenal sebagai tindak tutur. Tindak tutur dapat disampaikan melalui media lisan maupun tulisan, termasuk dalam media sosial yang memungkinkan ekspresi ide dan informasi secara luas. Teori tindak tutur pertama kali dikemukakan oleh John Langshaw Austin dan kemudian dikembangkan oleh muridnya, John Searle. Teori ini mengkaji hubungan antara bahasa dan tindakan, yang mencakup tiga tingkatan: lokusi (makna ujaran yang jelas), ilokusi (makna tersirat), dan perlokusi (dampak dari tindak tutur tersebut). Analisis ini penting untuk memahami dinamika sosial di sekolah dan bagaimana komunikasi mempengaruhi suasana belajar-mengajar. Tindak tutur ekspresif mencakup berbagai bentuk komunikasi seperti mengungkapkan kebahagiaan, kemarahan, belasungkawa, atau ucapan terima kasih, dan dapat diekspresikan melalui kata-kata, intonasi, ekspresi wajah, dan bahasa tubuh. Analisis ini juga dapat membantu mengidentifikasi masalah komunikasi yang mungkin terjadi dan mencari solusi untuk meningkatkan kualitas interaksi di lingkungan pendidikan.
Hemodynamic disturbances and dementia

Dementia is a common problem among older adults. Due to aging of the population, the number of people with dementia is expected to further increase in the coming decades. It is therefore important to have effective prevention and treatment strategies. Currently, these are unavailable, because – among other reasons – the disease processes that underly dementia are not fully understood.

An additional complicating factor is that there are different types of dementia, such as Alzheimer’s disease and vascular dementia. These two types of dementia are characterized by different, specific brain injury and consequently also by specific symptoms. However, Alzheimer’s disease and vascular dementia can coincide within the same person. This thesis therefore examined whether an impaired cerebral blood flow could be a common underlying mechanism for Alzheimer’s disease and vascular dementia.

Cerebral blood flow can be impaired as a consequence of disturbed blood pressure (such as with large variability in blood pressure) or by an obstruction of the blood flow to the brain (caused by an occluded carotid artery). This thesis showed that increased blood pressure variability was associated with brain injury that is related to vascular dementia. Increased blood pressure variability and an occluded carotid artery were not associated with brain injury that is related to Alzheimer’s disease.

This means that an impaired cerebral blood flow is not a common underlying mechanism for Alzheimer’s disease and vascular dementia, but it could be a potential target for prevention and treatment of vascular dementia.

Our knowledge of the assembly and dynamics of the cytokinetic contractile ring (CR) in animal cells remains incomplete. We have previously used super-resolution light microscopy and platinum replica electron microscopy to elucidate the ultrastructural organization of the CR in first division sea urchin embryos. To date, our studies indicate that the CR initiates as an equatorial band of clusters containing myosin II, actin, septin and anillin, which then congress over time into patches which coalesce into a linear array characteristic of mature CRs. In the present study, we applied super-resolution interferometric photoactivated localization microscopy to confirm the existence of septin filament-like structures in the developing CR, demonstrate the close associations between septin2, anillin, and myosin II in the CR, as well as to show that septin2 appears consistently submembranous, whereas anillin is more widely distributed in the early CR. We also provide evidence that the major actin cross-linking protein α-actinin only associates with the linearized, late-stage CR and not with the early CR clusters, providing further support to the idea that α-actinin associates with actomyosin structures under tension and can serve as a counterbalance. In addition, we show that inhibition of actomyosin contraction does not stop the assembly of the early CR clusters but does arrest the progression of these structures to the aligned arrays required for functional cytokinesis. Taken together our results reinforce and extend our model for a cluster to patch to linear structural progression of the CR in sea urchin embryos and highlight the evolutionary relationships with cytokinesis in fission yeast.

Introduction

The groundwater in arid countries such as Egypt represent the main water resources in the desert regions due to the long distance between these regions (oasis) and Nile River. Contamination of these limited water resources with toxic metals threaten the health of individuals in these regions.

Methods

The current study integrates isotopic tracers, hydrogeochemistry, geophysical logs, positive matrix factorization (PMF model), and Monte Carlo (MCS) simulation for pollution source apportionment and health risks associated with heavy metals in the Nubian Sandstone aquifer (NSSA).

Results and Discussion

The water resource used for drinking purposes (NSSA) is pale meteoric water (non-rechargeable aquifer). Silicate weathering, old trapped sea water, reverse ion exchange evaporation, and dissolution are the dominant mechanisms controlling water chemistry. PMF model showed that the major ions and heavy metals in groundwater of the NSSA originated from four significant sources (anthropogenic activities, dissolution of minerals, iron-bearing minerals, mixing with old trapped seawater, and hydrothermal water). The total risk (HI) oral values highlighted significant non-carcinogenic dangers for adults and children through the oral exposure. At the same time, dermal contact posed a no risk for adults and a high risk for children. Most samples had carcinogenic risk (CR) values higher than the allowed limits (1.0E-4) for metals like Cadmium, chromium, and lead, suggesting carcinogenic effects across all age groups. The Monte Carlo approach-based health concern evaluation model assessed the 5th % CR oral values (child) as 0.00012, 0.0036, and 0.0088 for Cd, Cr, and Pb, respectively, indicating more significant potential dangers to children. Urgent and comprehensive water treatment measures are imperative to mitigate the identified carcinogenic and non-carcinogenic health risks in the study area.
An education model to empower women in tech entrepreneurship

Introduction

The gender gap in technology entrepreneurship represents a significant and persistent disparity, with women significantly underrepresented in creating and leading technology start-ups. To address this multifaceted problem, it is critical to research and implement educational models that can foster intrinsic motivation in aspiring female entrepreneurs. Self-Determination Theory (SDT) provides a valuable framework for such an educational approach, emphasizing the importance of satisfying essential psychological needs—autonomy, competence and relatedness—to enhance motivation and commitment. Integrating SDT principles into entrepreneurship education can create supportive environments that empower women, encourage diverse perspectives, and ultimately bridge the gender gap in tech entrepreneurship. Particularly in the case of female students, it is important to understand how to empower their behavior choices to make possible different professional paths, with tech entrepreneurship being one of them. This gender gap has not yet been addressed through an education model proposal. Much has been said to characterize and identify it, but there is no proposal to change the higher education system in the STEM area, which is the research goal achieved in this paper: we need to analyze the gender gap in HEI and its relation to becoming entrepreneurial and understand how HEI may support the tech entrepreneurial behavior. To answer these questions we are going, in pursuit of the intrinsic motivations to support more entrepreneurial behavior in STEM female students.

Methods

A quantitative approach was designed to collect data to identify the gender gap in five European higher education institutions (HEI) in five different countries. In April, surveys were launched to female students, allowing a descriptive, exploratory factor analysis and structural equation modeling to test the SDT intrinsic motivation constructs.

Results

The results confirmed that there is a gender gap to overcome and that the teaching-learning process may help to potentiate the female student’s capacities of self-knowledge and self-value for female students. The autonomy need was identified as the most influential construct on students becoming entrepreneurs, not dishing the effect the competences and relatedness have. Understanding this reality allows for further development of the education model proposed and discussed.

Conclusion

Higher education lectures, particularly in STEM programs, can improve their teaching processes to become more inclusive and promote an effective entrepreneurial mindset. Understanding what will change helps engage in a different paradigm of education in technology, demystifying the concepts of entrepreneurship and allowing inclusion and gender equality in the higher education system.
