Least-cost or sustainable? Exploring power sector transition pathways

The 2022 energy crisis augmented the European ambition for RES capacity expansion. However, beyond the issue of “how many” renewables, the research question that remains, is which capacity mixes achieve the emissions reduction, renewable integration, and energy autarky targets in a cost-effective way. This paper tries to answer this inquiry supported by two energy models and one decision support model. The analysis focuses on Greece, as an example country which opted for lignite phase out, turning to temporary heavy reliance on natural gas for power generation. The results indicate that even though from the energy and environmental targets’ perspective, more wind turbines in the RES capacity mix yield better results, when incorporating the economic point of view, balanced wind and solar mixes enable the achievement of targets in a cost-effective way. The most cost-efficient mixes consist of 50–55% wind and 45–50% solar capacity, with cost per additional percentage of RES share in the generation mix, equal to 40 million €. Nevertheless, in order to materialize them in a timely manner, and limit the short-term dependency on imported gas, permitting simplification, tenders for large-scale projects and incentives for small-scale projects are needed to facilitate accelerated RES deployment.

An End-to-End Deep Learning Framework for Predicting Hematoma Expansion in Hemorrhagic Stroke Patients from CT Images

Hematoma expansion (HE) occurs in 20% of patients with hemorrhagic stroke within 24 h of onset, and it is associated with a poorer patient outcome. From a clinical point of view, predicting HE from the initial patient computed tomography (CT) image is useful to improve therapeutic decisions and minimize prognosis errors. In this work, we propose an end-to-end deep learning framework for predicting the final hematoma expansion and its corresponding lesion mask. We also explore the problem of having limited data and propose to augment the available dataset with synthetic images. The obtained results show an improved HE prediction when incorporating the use of synthetic images into the model, with a mean Dice score of the HE growth area of 0.506 and an average prediction error in hematoma volume of −3.44 mL. The proposed approach achieved results in line with state-of-the-art methods with far fewer data by using synthetic image generation and without requiring the inclusion of patient clinical data.

The use of various types of lighting in the interior of a residential space significantly improves the artistic expressiveness of the designed space.

Breastfeeding and fatty liver - is there any association?

The campaign to promote the natural feeding of infants, at least for the first six months of life, conducted over recent years has deep justification from a medical point of view. Numerous gynecological and pediatric societies around the world recommend breastfeeding as the most appropriate way of feeding infants. It has been proven that the benefits of this type of nutrition go beyond nutritional aspects, proper growth and development. The list of long-term metabolic benefits, which include reducing the incidence of obesity, allergies, infections and diabetes, is constantly growing. It has been shown that the method of feeding infants using various mechanisms may influence the tendency of the liver to accumulate fatty compounds and develop fatty liver disease with its metabolic consequences leading to liver failure, cirrhosis and hepatocellular carcinoma. This is an important discovery due to the growing obesity epidemic in adults and children. Metabolic dysfunction - associated fatty liver disease (MAFLD) has become the most common cause of chronic liver disease, affecting 25% of the global population. The results of studies conducted in recent years have shown the protective effect of breastfeeding on the risk of developing MAFLD later in life in both children and breastfeeding women. New scientific reports provide the basis for qualifying breastfeeding as a modifiable risk factor for MAFLD.

Quality and Accreditation Standards in Physical Education Colleges in Libyan Public Universities from the Point of View of Executive Management

This research aims to identify quality standards in physical education colleges in Libyan public universities, in relation with educational literature and the most important drivers of interest in implementing the quality assurance and accreditation system in universities. To achieve the research objectives, the descriptive method using the survey method was used. The sample consisted of ninety (90) individuals from the executive management in the colleges, thirty-eight (38) quality coordinators in the departments in the colleges, and fifty-two (52) department heads. In this research, a questionnaire form was applied that included four (4) axes and fifty-eight (58) statements, and statistical treatments were applied using the SPSS version 2020 software. The most important results of this study are that the college sets its goals based on its vision and mission in line with the needs of society through effective strategies announced in a public place to be a reference for evaluating progress in the college. It was also concluded that the college’s human resources (trainers and administrators) are sufficient to perform the tasks assigned to them through the work of committees and work teams and writing periodic reports on achievements, work performance, and development. The College Council also makes its decisions according to clear and specific tasks with the formation of distinguished work teams. One of the most important recommendations of the research is the college council’s approval of formulating the college’s vision and mission, the need to emphasize the presence of a quality and accreditation office in every college and unit for every department in the organizational structure of physical education colleges in Libyan public universities, and the necessity of developing a guideline for quality standards for accreditation in physical education colleges in Libyan public universities.

How do you know that you don’t know?

Whenever someone in a team tries to help others, it is crucial that they have some understanding of other team members’ goals. In modern teams, this applies equally to human and artificial (“bot”) assistants. Understanding when one does not know something is crucial for stopping the execution of inappropriate behavior and, ideally, attempting to learn more appropriate actions. From a statistical point of view, this can be translated to assessing whether none of the hypotheses in a considered set is correct. Here we investigate a novel approach for making this assessment based on monitoring the maximum a posteriori probability (MAP) of a set of candidate hypotheses as new observations arrive. Simulation studies suggest that this is a promising approach, however, we also caution that there may be cases where this is more challenging. The problem we study and the solution we propose are general, with applications well beyond human–bot teaming, including for example the scientific process of theory development.

Interaction diagrams of thin-walled, open cross section PC beams

Thin-walled, open cross section PC (prestressed concrete) beams are widely used in precast structures. Nevertheless, the analytical computation of their load carrying capacity under bending and torsion is still an unsolved problem. This is because of the markedly non-linear behaviour of both steel and concrete and of the asymmetry of the behaviour of concrete in tension and compression. This involves a search for the correct solution from a physical point of view (among those mathematically admissible) based on trial-and-error methods of numerical analysis.This paper suggests a method to evaluate the interaction diagrams under bending and torsion. According to this method the solving system is made by two equilibrium plus two compatibility equations. Some examples show the outcomes of this approach.

Chipping pedophiles as an alternative to chemical castration

BACKGROUND: This study considers chipping of persons who have committed sexual crimes against minors as an alternative to chemical castration. The fact that the issue of punishment for crimes against sexual inviolability of minors is less prioritized than the issue of prevention of these crimes is confirmed by disappointing statistics.
 AIM: To identify the advantages and disadvantages of chipping pedophiles in comparison with chemical castration.
 MATERIALS AND METHODS: This study analyzed the current legislation of Kazakhstan on the issue of chemical castration and chipping of pedophiles. SWOT analysis was used to determine the positive and negative aspects of chipping in pedophiles.
 RESULTS: Currently, the chipping of certain categories of citizens is illegal; however, there exists a legislative regulation of the use of electronic means of tracking suspects and convicted persons. Such means may well include biochips, and the expediency of enshrining chipping in criminal legislation as another coercive measure of medical nature has been substantiated.
 CONCLUSION: Chipping is cheaper than chemical castration from an economic point of view and safer from a medical point of view. The only reason chipping remains inferior to chemical castration is the issue of legislative regulation and data security, the solution of which is a matter of time.
 In conclusion, chipping pedophiles is a more effective and cheaper alternative to chemical castration. SWOT analysis showed the strengths and weaknesses of chipping pedophiles and the opportunities of this technology and potential threats to its use. Thus, the predominance of the strengths of technology over its weaknesses was revealed.

The Principle of Constructive Alternativeism and Physical Education. Introduction and purpose of the study

Nowadays, there is an active rethinking of the prospects for the development of physical education in educational institutions. This is manifested, in particular, in the aggravation of discussions about the expediency of using in our time such models of physical education as health-improving and adaptive, socially-oriented, personality-oriented, sports and recteative, which, as you know, differ in their goals and means of achieving them. In the course of these discussions, the proponents of some points of view reject the expediency of paying attention to the other approaches and offer their point of view as the "ultimate truth". In this work, an attempt is made to analyze the experience of getting out of similar situations in modern psychology and apply it to the field of physical education. The purpose of the study is to substantiate the expediency of using the principle of constructive alternativeism in physical education. Material and methods. In the process of research, the method of analysis and generalization of data from scientific and methodological literature was used. Results. The starting point of the study was the idea that approaches to the analysis of models of physical education should be carried out in the practical and theoretical planes. From a practical point of view, it is important to understand to what extent this or that model responds to the current demand of society, the complexity of organizational measures that are necessary for its implementation, the material base, etc. From the point of view of theory, the only thing that matters is to what extent our understanding of physical education as a phenomenon has been deepened and expanded. Conclusions. In the current conditions of martial law in Ukraine, the most expedient is the transition to a socially-oriented model of physical education. In the theory of physical education, it is advisable to focus on the principle of constructive alternativeism.

Sustainability and Resilience Assessment Methods: A Literature Review to Support the Decarbonization Target for the Construction Sector

It is a well-known issue that the 2050 target of carbon emissions neutrality will be reached only with the co-operation of all the interested sectors, and the construction sector could be one of the main contributors to this change. With the built environment globally responsible for about 40% of annual global energy-related CO2 emissions, the construction sector offers an important opportunity to drive transformative change and presents the most challenging mitigation potential among all industrial sectors, which also brings opportunities for adopting sustainability practices and increasing resilience. This paper presents a systematic literature review of those two pivotal concepts to reach the decarbonization goal: sustainability and resilience. Starting from an extensive literature review (2536 scientific documents) based on the PRISMA statement, the definitions and assessment methodologies of those concepts for the construction sector have been studied. The methodological approach followed for their analysis has been conducted on a first selection of 42 documents, further reduced to 12 by using clear inclusion criteria to identify the integrated assessment procedures. The main goal of this study is to clarify the correlation between sustainability and resilience concepts for constructions and their integrated assessment, in line with the latest regulations and market needs. The results show that, currently, sustainability and resilience are mainly evaluated in a distinct way to obtain building energy performance certificates, as well as to quantify the building market value and its complementary contribution to the ‘energy efficiency first’ principle and energy-saving targets towards the emergent issue of climate change. Few works focus on the integrated assessment of both concepts considering the construction industries’ point of view about materials and/or systems for buildings. The novelty of this study is the critical review of the current sustainability and resilience integrated assessment methods used for the construction value chain, declined for four main target groups. Researchers, policymakers, industries, and professionals could gain dedicated insights and practical suggestions to put in practice the elements of circular economy, ecological innovation, and cleaner production, which are essential in order to drive the decarbonization of the built environment.

Tunability of Microwave Frequency Using Spin Torque Nano Oscillator by the Generated Oersted Field with Tunable Free Layer

The current-induced magnetization precession dynamics provoked by the spin transfer torque (STT) in a spin valve device i.e. tri-layer device (commonly spin torque nano oscillator (STNO)) is investigated numerically by solving the governing Landau–Lifshitz–Gilbert–Slonczewski (LLGS) equation. In this study, we have devised an STNO device made of EuO-based ferromagnetic alloy in free and fixed magnetic layers. The copper acts as a nonmagnetic spacer. Here, we have introduced the current induced Oesterd field (CIOF), which is generated when a spin-polarized current passes through the STNO device. In the device, we have tuned the free layer angle [Formula: see text] from [Formula: see text] to [Formula: see text] as an increment of [Formula: see text]. For every individual [Formula: see text] ranging from [Formula: see text] to [Formula: see text], the generated Oersted field’s strength can be altered by increasing the STNO device’s diameter. Henceforth, it is apparent that the frequency tunability is achieved in the device for all the values of [Formula: see text]. The frequency and power of the device depend entirely on the material’s saturation magnetization, which inherently reflects the current density and coherence of spin-polarized DC. From the results, it is apparent that for a particular [Formula: see text], the frequency keeps increasing with the eventual decrease in power when we increase the strength of the Oersted field from 10[Formula: see text]kA/m to 50[Formula: see text]kA/m. By doing so, the maximum frequency can be tuned up to 212[Formula: see text]GHz for [Formula: see text] with [Formula: see text] as 50[Formula: see text]kA/m. The high frequency emitted by the device acts as a linchpin ingredient, as well as a launch pad element in much of scientific and technological point of view. It paves way for a new route in the areas such as high capacity, high precision, high density as well as the sensing applications.

Influence of Transformational Leadership and Teacher Collaboration on Teachers’ Ability in Implementing Interdisciplinary Learning

In today’s world, it is not enough for students to just learn from a single-track learning. Moreover, it is even more important for students as well as teachers to tackle issue they learn in the classroom from various points of views, one way is through an interdisciplinary learning approach. In order for teachers to be competent in applying interdisciplinary learning, the right type of leadership needs to guide these teachers. Besides the right type of leadership, teachers cannot tackle a particular issue on their own, there needs to be a collaboration among the teachers. The purpose of this quantitative study is to analyse the influence of transformational leadership and teacher collaboration on teachers’ ability in implementing interdisciplinary learning at XYZ Schools. Forty-seven teachers at XYZ Schools completed the online questionnaires. The path analysis through PLS SEM method was employed to test the proposed hypothesis. The results showed that transformational leadership has a positive influence on teachers’ ability in implementing interdisciplinary learning. Added to that, teacher collaboration has a positive influence on teachers’ ability in implementing interdisciplinary learning. Also, transformational leadership has a positive influence on teacher collaboration.

Navigating the vestibular maze: text-mining analysis of publication trends over five decades.

The field of vestibular science, encompassing the study of the vestibular system and associated disorders, has experienced notable growth and evolving trends over the past five decades. Here, we explore the changing landscape in vestibular science, focusing on epidemiology, peripheral pathologies, diagnosis methods, treatment, and technological advancements. Publication data was obtained from the US National Center for Biotechnology Information (NCBI) PubMed database. The analysis included epidemiological, etiological, diagnostic, and treatment-focused studies on peripheral vestibular disorders, with a particular emphasis on changes in topics and trends of publications over time. Our dataset of 39,238 publications revealed a rising trend in research across all age groups. Etiologically, benign paroxysmal positional vertigo (BPPV) and Meniere's disease were the most researched conditions, but the prevalence of studies on vestibular migraine showed a marked increase in recent years. Electronystagmography (ENG)/ Videonystagmography (VNG) and Vestibular Evoked Myogenic Potential (VEMP) were the most commonly discussed diagnostic tools, while physiotherapy stood out as the primary treatment modality. Our study presents a unique opportunity and point of view, exploring the evolving landscape of vestibular science publications over the past five decades. The analysis underscored the dynamic nature of the field, highlighting shifts in focus and emerging publication trends in diagnosis and treatment over time.

The study used the descriptive and analytical method, based on collecting data through a questionnaire that included two parts: the first to measure participatory leadership through the dimensions expressed, The second is to measure sustainable organizational performance through its dimensions as well. The study population consisted of (6) colleges, and the study sample amounted to (156) teachers, who were selected by a simple random method, and the statistical programs (AMOS V24) and (SPSS V26) were relied upon to analyze the data. The results of the study also showed that the two variables of the study (participatory leadership and sustainable organizational performance) in their dimensions are available in the field under study, in addition to identifying a positive and significant correlation between the two variables of the study, in addition to the presence of a positive and significant effect of participatory leadership on sustainable organizational performance. Based on the results, the researchers proposed a set of recommendations, the most important of which is the necessity of developing and empowering teachers in the studied colleges with the aim of increasing their experience and increasing their professional growth, developing the activities of teaching staff in the researched colleges and sustaining their performance to bring about change and improvement that is reflected in the quality of their services.

Green Hydrogen Value Chain: Modelling of a PV Power Plant Integrated with H2 Production for Industry Application

Based on the Sustainable Development Goals outlined in the 2030 agenda of the United Nations, affordable and clean energy is one of the most relevant goals to achieve the decarbonization targets and break down the global climate change effects. The use of renewable energy sources, namely, solar energy, is gaining attention and market share due to reductions in investment costs. Nevertheless, it is important to overcome the energy storage problems, mostly in industrial applications. The integration of photovoltaic power plants with hydrogen production and its storage for further conversion to usable electricity are an interesting option from both the technical and economic points of view. The main objective of this study is to analyse the potential for green hydrogen production and storage through PV production, based on technical data and operational considerations. We also present a conceptual model and the configuration of a PV power plant integrated with hydrogen production for industry supply. The proposed power plant configuration identifies different pathways to improve energy use: supply an industrial facility, supply the hydrogen production and storage unit, sell the energy surplus to the electrical grid and provide energy to a backup battery. One of the greatest challenges for the proposed model is the component sizing and water electrolysis process for hydrogen production due to the operational requirements and the technology costs.

Realizacja prawa do prywatności w rozumieniu poszanowania życia rodzinnego i wykonywania opieki rodzicielskiej w warunkach ubóstwa. Uwagi na gruncie wybranych norm prawa międzynarodowego publicznego i Europejskiej konwencji praw człowieka

Interference in family life is a particular form of threat to poor families, especially when the only impetus for state action in the form of an interference in the right to privacy is the poor material situation of the family. The article reflects on the possible threats to the realisation of family life within the framework of the right to privacy established under public international law, in particular the International Covenant on Civil and Political Rights, the Convention on the Rights of the Child and the European Convention on Human Rights (ECHR). In the view of the Human Rights Committee, the family should be oriented towards enabling the child to remain in the care of his or her parents or to return to their care or to other family members. The Committee on the Rights of the Child points out that the implementation of the right to privacy prohibits the recognition of material poverty as a basis and justification for taking a child out of parental care and into foster care. The European Court of Human Rights case law presented in the article confirms that children from poor families are at risk of being taken away from their parents and placed in foster care due to the financial status of the family, which may constitute a violation of the Article 8 of the ECHR. The fact that state authorities wrongly equate the lack of sufficient resources to support the family with child neglect poses a threat to the family life of poor individuals. Victims of violations of family bonds through harm to the private lives of family members should be protected under the human rights system. The following analysis makes it possible to identify the relevant problems from the point of view of the impoverished person or/and family, such as the questioning of parental capacity as a consequence of the erroneous equation of poverty with child neglect, or the withdrawal of the right to material assistance, all of which affect the realisation of family life, and further enables the identification of legal remedies for protection.
