    The importance of studying pollution via potentially toxic elements (PTEs) is becoming a key challenge considering the increasing concern about the presence of PTEs in the environment and their potential impacts on ecosystem functioning and public health due to their persistence and biotoxicity.Regional geochemical research, together with geostatistical computations which are used to identify source patterns of different pollutants related to the underlying geological features and/or anthropogenic activities, is the best approach for characterizing this pollution issue.The collection of research in this Special Issue, "Potentially Toxic Element Pollution in Urban and Suburban Environments", represents the need of the scientific community to characterize the behavior, transport, fate, and ecotoxicological state of PTEs in environmental matrices in both urban and suburban settings. All the case studies collected are of relevant significance due to their quality, both in the methodologies and the achieved results, and interest to different environmental studies, from China to South Africa to Europe.My role as Guest Editor of this Special Issue was exciting and stimulating. I would like to express my appreciation to all the authors for submitting their original contributions and to the reviewers for their essential role in the process. I would like to thank the editors of Toxics and, in particular, Selena Li for her precious and tireless support.

    This reprint focuses on wear and fatigue analysis, the dynamic properties of coating surfaces in transmission systems, and non-destructive condition monitoring for the health management of transmission systems.Transmission systems play a vital role in various types of industrial structure, including wind turbines, vehicles, mining and material-handling equipment, offshore vessels, and aircrafts. Surface wear is an inevitable phenomenon during the service life of transmission systems (such as on gearboxes, bearings, and shafts), and wear propagation can reduce the durability of the contact coating surface. As a result, the performance of the transmission system can degrade significantly, which can cause sudden shutdown of the whole system and lead to unexpected economic loss and accidents. Therefore, to ensure adequate health management of the transmission system, it is necessary to investigate the friction, vibration, and dynamic properties of its contact coating surface and monitor its operating conditions.

    The global coronavirus pandemic has highlighted the paramount importance of immune health and the nutrient status of peoples worldwide. Vitamins C and D have important roles in both the innate and adaptive immune systems and are known to support healthy immune function. Both vitamins C and D have gene regulatory roles with the ability to up- and down-regulate thousands of genes, thus playing pleotropic roles in human health and disease. People from low- and middle-income countries tend to have inadequate micronutrient intakes and status, as do specific subgroups from high-income countries. This can affect their resistance to both communicable and non-communicable diseases and the severity of these diseases. In this Special Issue, we have compiled review articles and research papers (both observational and interventional studies) that explore the role of vitamins C and D in numerous aspects of global and population health.

    From the 1970s onwards, many towns and cities have experienced deindustrialization processes, while seeing a gradual growth of tertiarization and diversification of services, including cultural ones. With the different, both positive and negative, effects introduced by new cultural interpretations of cities (e.g., culture in public spaces, cultural and creative industries, culture as marketing tools, cultural commodification, etc.), the concept of culture has become increasingly associated with urban image and identity. In finding solutions within regeneration processes, policies often rely on tools from the cultural and creative fields. Additionally, built material and immaterial heritage can have significant roles: e.g., by converting heritage sites and buildings through cultural projects or new functions, or capitalizing on specific traditions and place memory for local identity and place attachment. This SI focuses on cultural approaches in connection with urban development and gather contributions from various research fields. It addresses researchers and academics from social sciences who are interested in topics such as: cultural activities and their role in urban development; cities (re)constructing their identity; culture as a relevant component of current spatial planning policies; urban strategies, attracting creative people; urban image, heritage and culture; culture, local memory and local identities; heritage and industrial culture; subcultures within cities and processes of urban change.

    Dynamic stability basically deals with the interactions between the system's components. Following a disturbance, the system's variables undergo transitions that can induce oscillations in active and reactive power generation, resulting in the occurrence of voltage oscillatory modes and frequency deviation in the system. Depending on the entity of the disturbance, the small- or large-signal stability of the system under consideration can be investigated. The introduction of RES-based generation that does not participate in the network services (i.e., frequency and voltage regulation) due to lack of special controls will undoubtedly affect both the overall frequency and voltage stability. Large-scale transient stability is also a concern not to be overlooked: inverter-based wind and solar generation have different angle/speed swing behaviors with respect to traditional generation due to reduced inertia, different voltage swing behaviors due to different voltage control systems, different power flow patterns, and different displacements of synchronous generation at key locations. Therefore, although power system stability and dynamics have played a very central role in the management and study of electrical power systems thus far, it is also true that the emerging scenario requires new methodologies, technologies, and analyses. In this light, the current Special Issue aims to collect contributions (i.e., research papers and review articles) on power system dynamics and stability from experts in academia and industry.

    Cumulative evidence demonstrates that healthy nutrient intake and regular physical exercise are both powerful lifestyle strategies that modulate lifelong health through their ability to improve body composition, musculoskeletal health, sex steroid hormones, sleep quality, and physical and cognitive performance, as well as to prevent chronic diseases across the lifespan, especially in women. While the benefits of nutrition and physical exercise are commonly studied separately, the integration of nutrition and physical exercise has the potential to produce greater benefits in women than strategies focusing only on one or the other. Studying the specificities of women in response to interventions is of the utmost importance for providing optimal healthcare and aids the design of guidelines that are better suited for women. A better knowledge regarding nutrient intake and physical exercise and their interaction in women is therefore needed. This Special Issue entitled "nutrient intake and physical exercise as modulators of healthy women" will comprise manuscripts that highlight this integrational approach as a potential modulator of lifelong outcomes in women.

    Rainfall is the main input for all hydrological models, such as rainfall-runoff models and the forecasting of landslides triggered by precipitation, with its comprehension being clearly essential for effective water resource management as well. The need to improve the modeling of rainfall fields constitutes a key aspect both for efficiently realizing early warning systems and for carrying out analyses of future scenarios related to occurrences and magnitudes for all induced phenomena. The aim of this Special Issue was hence to provide a collection of innovative contributions for rainfall modeling, focusing on hydrological scales and a context of climate changes.We believe that the contribution from the latest research outcomes presented in this Special Issue can shed novel insights on the comprehension of the hydrological cycle and all the phenomena that are a direct consequence of rainfall. Moreover, all these proposed papers can clearly constitute a valid base of knowledge for improving specific key aspects of rainfall modeling, mainly concerning climate change and how it induces modifications in properties such as magnitude, frequency, duration, and the spatial extension of different types of rainfall fields. The goal should also consider providing useful tools to practitioners for quantifying important design metrics in transient hydrological contexts (quantiles of assigned frequency, hazard functions, intensity-duration-frequency curves, etc.).

    The World Health Organization (2002) classified violence as a leading international public health problem that requires immediate intervention. Violence is a pervasive social problem whose causes and consequences are inextricably linked to individuals, families, institutions, communities, and societies. The negative consequences of violence, and serious violence in particular, reverberate beyond the immediate moment and location of it. By bringing together partners with varied skills, whole-system multiagency approaches are advocated as the leading means of targeting serious violence. With this context in mind, this Special Issue examines a variety of collaborative, community-based approaches to preventing and reducing serious violence across the global landscape. The contributions from practitioners and researchers focus on the prevention and reduction of serious interpersonal violence in communities. The typologies of serious violence discussed by the collaborators include gang membership, domestic violence, and sexual violence. The contributions address the collaborative nature of serious violence prevention work, recognizing that violence is multicausal and that solutions are needed across various socioecological domains. The contributions describe community-level collaborative approaches to preventing and reducing serious violence. The successes and lessons learned from the approaches are identified, and the applicability of the approaches to other areas are explored.

    At present, the increasing demand for novel biotechnological products is supported through the continuous development of biocatalytic applications. As a consequence, the progress of research regarding enzymatic catalysis in aqueous, non-aqueous, organic (polar or non-polar), and/or non-solvent media is decisive. Experimental design methods, which also may comprise in silico studies, the design of specific reactors and conditions, the reactions of significant chemical and/or biochemical processes that are relevant to industrial production, enzyme kinetic methods, the investigation of enzymatic mechanisms and the use of immobilized enzymes and/or microbial cells on various inert matrices, are all useful. A plethora of enzymes of several classes, which may potentially be used as biocatalysts in biotechnological applications, are available. Among these enzymes, the more common are oxidoreductases (laccase, catalase, glucose oxidase, etc.), hydrolases (amylases, lipases, proteases, amidases, cellulases, esterases, etc.), isomerases (epimerases, topoisomerases, mutases, etc.), and others. By means of the aforementioned biocatalysts and the utilization of specific biotechnological methods, important, cost-effective, sustainable, and environmentally friendly processes have been applied for the synthesis and/or the conversion of a huge number of market-required products.

    In this Special Issue of Genes entitled "Genetic Conditions Affecting the Skeleton: Congenital, Idiopathic Scoliosis and Arthrogryposis", evidence is presented that suggests that congenital, idiopathic scoliosis, and arthrogryposis share similar overlapping, but also distinct, etiopathogenic mechanisms, including connective tissue and neuromuscular mechanisms. Congenital scoliosis (CS) is defined by the presence of an abnormal spinal curvature, due to an underlying vertebral bony malformation (VM). Idiopathic scoliosis (IS) is defined by the presence of an abnormal structural spinal curvature of ¿10 degrees in the sagittal plane, in the absence of an underlying VM. Arthrogryposis is defined by the presence of congenital contractures in two or more joints of the appendicular skeleton. All three conditions have complex genetic causes. This Special Issue highlights the complex nature of these conditions and current concepts in our approach to better understand their genetics.
