    Description: Work is central to people’s lives and the course of their life. The opportunities and chances an individual can have in their life are significantly connected to work. Individuals' work is also crucial for organisations, companies and for the whole of society. There is a constant need to make changes and readjustments of working life since these can deeply affect the individual and their employability. To make working lives more healthy, sustainable and attractive, being aware of the measures and changes that can be achieved in practice is of crucial importance. This book bridges the gap between the theories and explanatory models offered in research and actual work environments and workplaces. This book constitutes a theoretical framework that visualises the complexity of working life and increases the knowledge and awareness of individuals, companies, organisations and society regarding different factors and patterns. It aims to support individual reflections and joint discussions into daily operations on the individual, organisational and societal level. This book contains practical tools to use in daily working life that analyse possible risks in the work environment when planning measures and actions for health promotion. These practical tools are derived from the four spheres for action and employability in the SwAge model. Developed by the author, the SwAge model (Sustainable Working Life for All Ages) is a theoretical, explanatory model that explains the complexity of creating a healthy and sustainable working life for all ages. By using the SwAge model as a comprehensible framework, the reader will be able to visualise the complexity of factors that affect and influence whether people are able to and want to participate in working life and in the work environment, thereby contributing to increased employability. Designing Sustainable Working Lives and Environments is an essential read for students, researchers, work environment engineers, ergonomics and human factor specialists, occupational health and safety practitioners, business managers, HR staff, leadership decision-makers and labour union professionals.

    Description: Chapter 9 - The heterogeneous Fenton process can generate a large number of compounds that can be toxic to the environment, and more toxic by-products than the parent compounds can appear after the treatment process. The heterogeneous Fenton process is used to decompose contaminants by rapid oxidation in the presence of a catalyst. Iron oxides, commonly used as catalysts, are considered to be non-toxic, but there are reports of toxicity towards certain organisms. Therefore, studies on the stability of the catalysts used in the process and their potential threats to living organisms are necessary. It is essential to constantly work on the stability of the catalyst. The toxicity of the by-products is also crucial. According to the reports, the decrease in viability of organisms is organism-specific and dose-dependent, and the lethal effect is strictly related to the size of particles. Incomplete mineralization can also result in hazardous, potentially toxic compounds in the effluent. Thus, the toxicity of effluent also needs to be studied, and biodegradability needs to be increased to reduce the toxicity of the process.

    Description: Chapter 3 - The right choice of catalyst is one of the elements that determine its effectiveness. Among the most commonly used catalysts, we use iron, as well as its modifications and forms such as zero-valent iron, iron oxides, etc. magnetite (Fe3O4), hematite (Fe2O3), and goethite (FeOOH) or their nanoparticles. They have a high surface area, which enhances their catalytic activity and can be easily separated from the treated water. Another popular and environmentally friendly form is waste iron, which is the product from industry such as blast furnace slag or steel slags. Moreover, iron could be dropped on carbon materials, and various carriers.

    Description: In this book for researchers and students, editors Shiomi and Sumioka bring together contributions from researchers working on the CREST project at ATR Deep Interaction Laboratories, a world leader in social robotics, to comprehensively describe robot touch systems from hardware to applications. Appropriate touch from robots to humans is essential for social robots, but achieving this requires various solutions at every stage of the touch process. Through this book, readers will gain an understanding of the needs, essential systems and communication cues, behaviour designs, and real‑world issues for social touch applications. This book compiles and updates technical and empirical research that was previously scattered throughout the literature into a single volume. Through individually authored chapters addressing various elements of ATR’s CREST project, this book tackles key areas where understanding is needed to realize acceptable touch interaction, including pre‑touch interaction, interaction design for touching and being touched, behaviour changes caused by touch interaction, and applications of social touch interaction. It introduces a touch sensor and robots developed by the authors, including several touch‑related behaviours and design policies. This approach will enable readers to easily apply this knowledge to their own social robotics programs. This book is invaluable for anyone who wishes to understand and develop social robots that physically interact with people. It is most beneficial for researchers and upper undergraduate and graduate students in the fields of human–robot/agent/computer interaction and social touch interaction and those in the broader fields of engineering, computer science, and cognitive science.

    Description: Global declines in biodiversity have become increasingly severe. Traditional monitoring approaches for assessing marine species distributions and abundances are time consuming, costly, and manpower intensive. Fortunately, rapid progress of sequencing technologies from first-generation to high-throughput sequencing have resulted in improvements in experimental techniques. These advances have accelerated rates of species discovery and identification, enabling community-level biomonitoring – the ‘Biomonitoring 2.0’ framework. Simultaneous multispecies identifications in mixed-sample pools are now mainstream with DNA metabarcoding, upscaling monitoring from the individual specimen to the ecosystem scale. In this review, we examine the progress of DNA metabarcoding over the last decade in the characterisation of marine macrobiota to microbial communities. By melding molecular techniques and more traditional taxonomic tools, this integrative Biomonitoring 2.0 approach is tailored to improve the overall effectiveness of biomonitoring. As such, we here assess its accuracy, expertise requirement, general applicability, time, cost-effectiveness, and throughput for biomonitoring. We highlight various methodological challenges that must be considered during implementation, including completeness of reference databases, representativeness of sequencing read counts for quantitative estimates, and supplementation with environmental RNA for discerning live signals from legacy DNA. Finally, we conclude with an outlook of the enhanced Biomonitoring 2.0 framework for mass adoption by ecologists and managers, as well as the prospects of emerging rapid detection technologies for ecosystem surveillance.

    Description: During the evolvement of autonomous driving technology, obtaining reliable 3-D environmental information is an indispensable task in approaching safe driving. The operational behavior of automotive radars can be precisely evaluated in a virtual test environment by modeling its surrounding, specifically vulnerable road users (VRUs). Such a realistic model can be generated based on the radar cross section (RCS) and Doppler signatures of a VRU. Therefore, this work proposes a high-resolution RCS measurement technique to determine the relevant scattering points of different VRUs.

    Description: The Central and South Atlantic represents a vast ocean area and is home to a diverse range of ecosystems and species. Nevertheless, and similar to the rest of the global south, the area is comparatively understudied yet exposed to increasing levels of multisectoral pressures. To counteract this, the level of scientific exploration in the Central and South Atlantic has increased in recent years and will likely continue to do so within the context of the United Nations (UN) Decade of Ocean Science for Sustainable Development. Here, we compile the literature to investigate the distribution of previous scientific exploration of offshore (30 m+) ecosystems in the Central and South Atlantic, both within and beyond national jurisdiction, allowing us to synthesise overall patterns of biodiversity. Furthermore, through the lens of sustainable management, we have reviewed the existing anthropogenic activities and associated management measures relevant to the region. Through this exercise, we have identified key knowledge gaps and undersampled regions that represent priority areas for future research and commented on how these may be best incorporated into, or enhanced through, future management measures such as those in discussion at the UN Biodiversity Beyond National Jurisdiction negotiations. This review represents a comprehensive summary for scientists and managers alike looking to understand the key topographical, biological, and legislative features of the Central and South Atlantic.

    Description: The Congress ""Arsenic in the Environment"" offers an international, multi- and interdisciplinary discussion platform for research and innovation aimed towards a holistic solution to the problem posed by the environmental toxin arsenic, with significant societal impact. The Congress has focused on cutting edge and breakthrough research in physical, chemical, toxicological, medical, agricultural and other specific issues on arsenic across a broader environmental realm. The Biennial Congress ""Arsenic in the Environment"" was first organized in Mexico City (As2006) followed by As2008 in Valencia (Spain), As2010 in Tainan (Chinese Taiwan), As2012 in Cairns (Australia), As2014 in Buenos Aires (Argentina) and As2016 in Stockholm (Sweden). The 7th International Congress As2018 was held July 1-6, 2018, in Beijing, P. R. China and was entitled Environmental Arsenic in a Changing World. The Congress addressed the broader context of arsenic research aligned on the following themes: Theme 1: Arsenic Behaviour in Changing Environmental Media Theme 2: Arsenic in a Changing Agricultural Ecosystem Theme 3: Health Impacts of Environmental Arsenic Theme 4: Technologies for Arsenic Immobilization and Clean Water Blueprints Theme 5: Sustainable Mitigation and Management Arsenic in drinking water (mainly groundwater) has emerged as an issue of global health concern. During last decade, the presence of arsenic in rice, possibly also other food of plant origins, has attained increasing attention. This is particularly true in the Asian countries, where the use of high arsenic groundwater as source of irrigation water and drinking water has been flagged as severe health concern. This has been accentuated by elevating arsenic concentrations in deep groundwater recharged from shallow high arsenic groundwater, which may have further detrimental effects on public health. Notably, China has been in the forefront of research on arsenic biogeochemical cycling, health effects of arsenic, technologies for arsenic removal, and sustainable mitigation measures. The Congress has attracted professionals involved in different segments of interdisciplinary research on arsenic in an open forum, and strengthened relations between academia, research institutions, government and non-governmental agencies, industries, and civil society organizations to share an optimal ambience for exchange of knowledge.

    Description: Methemoglobinemia is characterized by a blue color to the skin, hypoxia that does not respond to administered oxygen, chocolate-colored blood, and shortness of breath. There are two main types of methemoglobinemia. The first type, congenital, is a genetic disease that can vary from very few minor symptoms to a severe disorder with significant neurological problems. The second type is acquired methemoglobinemia. This type of methemoglobinemia is characterized by exposure to an oxidizing agent, pharmaceutical, or chemical that can create transitory methemoglobinemia. Although it is transient, it can still be severe depending on what percentage of hemoglobin is converted to methemoglobin. At levels above 70 percent it can be fatal. Nitrate is one example of a chemical that can cause methemoglobinemia. After ingestion, the nitrate is converted to nitrite in the back of the mouth. Nitrite can then enter the bloodstream where it interacts with hemoglobin. The human body has two enzyme systems to keep the concentration of methemoglobin low, but those systems can be overwhelmed, allowing for methemoglobinemia to develop. There are several sources of nitrite and nitrate: some pharmaceuticals, contaminated water, prepackaged food, preserved meats, and vegetables such as zucchini and spinach.

    Description: To keep up with the ever-increasing data transmission speed needs, data center interconnects are scaling up to provide multi-Tbit/s connectivity. These links require a high number of WDM channels, while the associated transceivers should be compact and energy efficient. Scaling the number of channels, however, is still limited by the lack of adequate optical sources. In this book, we investigate novel chip-scale frequency comb generators as multi-wavelength light sources for Tbit/s WDM links.

    Description: This book focuses on the amphibian, Xenopus, one of the most commonly used model animals in the biological sciences. Over the past 50 years, the use of Xenopus has made possible many fundamental contributions to our knowledge in cell biology, developmental biology, molecular biology, and neurobiology. In recent years, with the completion of the genome sequence of the main two species and the application of genome editing techniques, Xenopus has emerged as a powerful system to study fundamental disease mechanisms and test treatment possibilities. Xenopus has proven an essential vertebrate model system for understanding fundamental cell and developmental biological mechanisms, for applying fundamental knowledge to pathological processes, for deciphering the function of human disease genes, and for understanding genome evolution. Key Features Provides historical context of the contributions of the model system Includes contributions from an international team of leading scholars Presents topics spanning cell biology, developmental biology, genomics, and disease model Describes recent experimental advances Incorporates richly illustrated diagrams and color images Related Titles Green, S.

    Description: In recent years, OFDM has become more and more important for radar applications. A disadvantage, however, is the need for high sampling rates, which is exactly the starting point of the frequency comb OFDM radar scheme. With its help, the bandwidth in the radar channel can be enhanced without increasing the sampling rates at the same time. In this way, a high range resolution can be achieved without using fast converters with high sampling rates.

    Description: By providing a high resolution at high distances in a broad field of view, LiDAR sensors are a key element in automated driving cars. However, in harsh environmental conditions, particles from rain or dust attach on the outer surface of the sensor and cause a degradation of the overall performance. This work introduces several methods to detect and characterize those particles, realizing the integration of an intelligent and fully automated cleaning system to restore the required performance.

    Description: In this work describes the development of a light-based driver assistance system through projections on the road. Under realistic conditions it is shown that information can be transmitted to the driver at night by using projections in front of the vehicle: test persons drive more safely through narrow spaces and react earlier to obstacles. A prototype suitable for road use demonstrates the possibility of a near-series implementation of such a headlamp projection system.

    Description: In this work, two methods are developed and evaluated to integrate and test functional chains of automotive lighting functions on simulation-based test systems. The focus is initially on an approach for the efficient use of light for the display of high contrasts in virtual night driving with a real driver assistance camera. Furthermore, a test method is developed to evaluate pixel-based lighting functions on a hardware-in-the-loop test system based on metrics. In this work, two methods to stimulate and test automotive front lighting functions on simulation-based test benches are developed and evaluated. The first approach deepens the idea to reach necessary high contrasts for virtual night driving with a real driver assistance camera by an efficient use of reflecting light. Furthermore, a test method is shown to test pixel-based lighting functions based on metrics on a hardware-in-the-loop test bench.
