Each battery cell consists of three main components: the anode, the cathode, and the separator soaked with liquid electrolyte, the medium in the battery that allows charged ions to move between the two electrodes. Besides a wide electrochemical stability window and good compatibility with both electrodes, the electrolyte should also be safe, thermally stable and environmentally benign, showing a high ionic conductivity of the charge-carrying Li ions and finally a low price. This unique combination of properties is impossible to achieve with a simple salt–solvent mixture and usually requires a combination of different electrolyte components, i.e., several liquid solvents and additives and one or more conducting salt(s). For lithium-based batteries, which are the most common electrochemical energy storage devices today, a solution based on lithium hexafluorophosphate (LiPF6) in a mixture of organic carbonates as the solvent is used. Usually, the conducting salt concentrations used for lithium-based electrolytes are in the range of ≈1 to 1.2 M, but recently, electrolytes with much higher conducting salt concentrations of 5 M and even over 10 M have been investigated as they offer several benefits ranging from increased safety to a broadened electrochemical stability window, thus enabling cheap and safe solvents, even water.

The term “urban planning for the contemporary age” describes the process of creating and overseeing urban areas to meet the many complex issues of the current times, such as social justice, climate change, growing urbanisation, and technological advancement. It places a strong emphasis on flexible, inclusive, and progressive approaches that strike a balance between sustainable development and the changing demands of various urban populations. Urban planning, particularly in the contemporary age, is a multidisciplinary discipline that tackles the complexity of contemporary cities that is influenced by social injustices, fast urbanisation, climate change, and technology breakthroughs. This entry paper examines how planners deal with these issues by using flexible, inclusive, and sustainable approaches that strike a balance between community well-being, environmental conservation, and growth. It looks at important topics including incorporating smart technology, building climate impact resilience, and creating inclusive, accessible, and egalitarian urban environments. The conflict between tradition and modernisation is also highlighted in the chapter, underscoring the necessity of creative solutions that protect cultural legacy while meeting contemporary needs. By examining global trends, this study offers insights into how urban planning is changing to satisfy the demands of a dynamic and connected society. The study used a literature review to identify the main areas that are influencing innovation in urban planning. It then delves into discussions on contemporary issues and complexities in shaping urban futures. The main research methods were a literature review and empirical analysis. In the end, it makes the case for rethinking urban futures with an emphasis on resilience, sustainability, and the welfare and well-being of urban residents.

The Likert-type scale is a widely used psychometric instrument for measuring attitudes, opinions, or perceptions in research contexts. It presents respondents with a series of statements accompanied by symmetrical response options, typically structured on a five-point scale ranging from “Strongly Disagree” to “Strongly Agree”. Each point on the scale represents a gradation of agreement or sentiment, allowing researchers to transform subjective responses into quantifiable data for statistical analysis and interpretation.

This entry explores the financial impact of the COVID-19 pandemic on the football industry, highlighting the challenges, adaptations, and long-term implications for clubs across all levels. It examines the industry’s financial fragility, particularly for clubs reliant on matchday revenue, while showcasing adaptive strategies such as digital engagement, government support, and revenue diversification that sustained operations during the crisis. The pandemic exposed structural vulnerabilities within football, from elite clubs to grassroots teams, through revenue shortfalls caused by closed stadiums, cancelled matches, and reduced sponsorships. This study provides a comprehensive analysis of the pandemic’s effects on revenue streams, fixed costs, player contracts, and stakeholder roles, offering insights into strategies that promote financial resilience. Case studies illustrate how elite, semi-professional, and grassroots clubs responded to financial and operational challenges, emphasising the importance of diversified income sources, proactive financial planning, and community support. By identifying lessons from the pandemic, the entry underscores the critical need for sustainable practises and resilient models to prepare the football industry for future disruptions.

Definition: Poverty is an important social determinant of health disparities across the lifespan. Poverty also influences other life challenges such as pecuniary instability, food insecurity, housing instability, educational inequality, and limited career mobility. According to the World Bank, more than 700 million people worldwide live in global poverty, surviving on less than USD 2.15 a day. Poverty may also be viewed as a state of deprivation that limits access to resources that address basic needs (i.e., food, water, shelter, clothing, health), limiting an individual’s opportunity to participate optimally in society. A large body of research has identified a positive relationship between poverty and chronic health concerns such as heart disease, diabetes, high cholesterol, kidney problems, liver problems, cancer, and hypertension. This entry examines health disparities associated with economic status, discrimination, racism, stress, age, race/ethnicity, gender, gender identity, and nationality from a social justice perspective.

The kidney, a complex organ crucial for a multitude of homeostatic functions, including the maintenance of fluid and electrolyte balance, removal of various metabolic waste products, and hormone production, undergoes intricate developmental processes to form functional nephron units. Understanding the mechanisms behind kidney development is paramount for elucidating the etiology of renal congenital disabilities and acquired diseases. The Hippo pathway is known for its involvement in various cellular functions, including cell fate determination and differentiation, and is a critical player in renal organogenesis. Here, we discuss research findings about the roles that Hippo signaling plays in kidney formation.

This entry explores the emergence of ONE Paleopathology as a holistic, interdisciplinary approach to understanding health through deep time. The entry discusses key areas where paleopathological research provides crucial insights: animals as sentinels of environmental health, the evolution and transmission of infectious diseases, the impacts of urbanization and pollution on human health, and the effects of climate change on disease patterns. Special attention is given to case studies involving malaria, tuberculosis, and environmental toxicity, demonstrating how past human–environment interactions inform current health strategies. The entry also emphasizes the importance of indigenous and local knowledge (ILK) systems in understanding and managing health challenges, highlighting how traditional ecological knowledge complements scientific approaches. By bridging past and present, ONE Paleopathology offers valuable perspectives for addressing modern health challenges in the context of accelerating environmental change, while promoting more equitable and sustainable approaches to global health.

Clinical reasoning is an essential competence of veterinary graduands. Unfortunately, clinical reasoning and, therefore, the quality of provided veterinary medical services are prone to bias, difficulties, and errors. The literature on biases, difficulties, and errors in clinical reasoning in veterinary medical education is scarce or focused on theoretical rather than practical application. In this review, we address the practicality of learning and teaching biases, difficulties, and errors in clinical reasoning to veterinary learners utilizing a practical example of a cow with a prolapsed uterus complicated by hypocalcemia and hypomagnesemia. Learners should be guided through all of the stages of clinical reasoning as much as possible under direct supervision. The common clinical biases, difficulties, or errors in veterinary medical encounters may differ between stages of development of the learner, with more difficulties occurring in earlier stages (Observer, Reporter, ±Interpreter) but more heuristic biases occurring at later stages (Manager, Educator, ±Interpreter). However, clinical errors may occur at any learner development stage. Therefore, remediation of clinical biases, difficulties, and errors in veterinary medical encounters should use strategies that are tailored to the level of development of the learner, but also to the specific encounter (e.g., client, patient, and context).
