Sommario/riassunto

This book discusses Hong Kong’s use of onscreen marking (OSM) in public examinations. Given that Hong Kong leads the way in OSM innovation, this book has arisen from a recognised need to provide a comprehensive, coherent account of the findings of various separate but linked validation studies of onscreen public examinations in Hong Kong. The authors discuss their experience of the validation process, demonstrating how high-stakes innovation should be fully validated by a series of research studies in order to satisfy key stakeholders.

Nota di contenuto

1. Overview, aims and scope -- 2. Economic costs of nitrogen management in agriculture -- 3. Economics of low nitrogen feeding strategies -- 4. Ammonia abatement by animal housing techniques --



5. Ammonia abatement with manure storage and processing techniques -- 6. Cost of ammonia emission abatement from manure spreading and fertilizer application -- 7. Co-benefits and trade-offs of between greenhouse gas and air pollutant emissions for measures reducing ammonia emissions and implications for costing -- 8. Country case studies -- 9. Estimating costs and potential for reduction of ammonia emissions from agriculture in the GAINS model -- 10. Costs of ammonia abatement: summary, conclusions and policy context.

Sommario/riassunto

This book examines the costs involved in reducing ammonia emissions from agricultural practices as well as the potential benefits for climate change mitigation. It features contributions by experts in agricultural production processes, producers of agricultural equipment and service providers as well as scientists who assess the issue from an European perspective.   Coverage examines all agricultural production stages starting from animal feed and housing, including the storage and application of liquid and solid manure and of mineral fertiliser. In addition, the book looks at the relationship between ammonia control and greenhouse gas emissions and details the GAINS (Greenhouse Gas and Air Pollution Interactions and Synergies) model for estimating costs and reducing ammonia emissions from agriculture. Examples and case studies from select European countries, including Italy, Switzerland, Russia, Ireland, and Spain, provide readers with detailed studies of ammonia abatement costs and the effectiveness of implementing control measures under different conditions. This book is the result of an Expert Workshop held under the auspices of the UNECE Convention on Long-range Transboundary Air Pollution (CLRTAP) and organised by the Task Force on Reactive Nitrogen (TFRN). The findings of this workshop have informed the development of documents supporting the revision of the Gothenburg Protocol and provided researchers and practitioners with vital new data. Bringing together a wealth of key information on the costs of ammonia abatement and the climate co-benefits, this monograph provides readers with deep insight into this complex issue.

1 Introduction -- 2 The logarithmic spiral -- 3 The Archimedean spiral -- 4 Screws -- 5 Angular logarithmic spirals -- 6 Angular Archimedean spirals -- 7 Curvature -- 8 Golden spirals -- 9 Optical illusions -- 10 Spherical spirals.

Sommario/riassunto

In this book you will discover the mathematical patterns and regularities of various spirals, helixes and spiral-like figures. Their geometric aspects and connections are presented in a visually appealing way and are supplemented as best as possible with analytical aspects and representations. Using examples from technology and nature, you will learn about round, square, golden and spherical spirals and examine their curvature behavior and other exciting properties. The examples are arranged thematically and the book has a modular structure so that the individual chapters can be read largely independently of each other. It is therefore a valuable resource for students, pupils, (prospective) teachers, those interested in mathematics and those who want to become one. Additional

The translation was done with the help of artificial intelligence. A subsequent human revision was done primarily in terms of content. The Author Dr. Hans Walser was a high school teacher and lecturer at the ETH Zurich, the University of Basel and the Basel University of Education in the areas of teacher training and mathematics for natural and engineering students.
