This volume represents an effort to bring together communities of land-based hydrogeology and marine hydrogeology. The issues of submarine groundwater discharge and its opposite phenomenon of seawater invasion are discussed in this book from the geophysical, geochemical, biological, and engineering perspectives. This is where land hydrogeology and marine hydrogeology overlap. Submarine groundwater discharge is a rapidly developing research field. The SCOR and LOICZ of the IGBP have recently established a working group for this research. IASPO and IAHS under IUGG also recently formed a new joint committee "Seawater/Groundwater Interactions" to collaborate with oceanographers and hydrologists. The other articles introduce frontier research topics in more typical land and marine environments, such as fluid flow in karst aquifers, the biological aspects of fluids in sedimentary basins and submarine sedimentary formations, respectively, and vigorous fluid flow in subsea formations and their significance in global tectonics. Geochemical characteristics of hydrothermal activities at a number of active continental margins are also reviewed, and multidisciplinary geophysical constraints of the permeability of young igneous oceanic crust are summarized. A variety of driving mechanisms for fluid flow is discussed in land and subsea formations; terrestrial hydraulic gradient, buoyancy driven free convection, tidally induced flow, flow induced by tectonic strain, flow due to sediment compaction.

This specially curated collection features five reviews of current and key research on fruit losses and waste.The first chapter reviews the magnitude of losses and waste of fruit and vegetables as well as key issues in estimating losses. It provides a detailed assessment of the main causes of losses and waste together with strategies for their prevention.The second chapter assesses the adoption of new, non-destructive technologies as a way of measuring harvest maturity and improving sorting operations to minimise the risk of product loss and waste.The third chapter outlines the importance of harvest management of apples and considers the importance of various factors associated with fruit physiology, maturation and ripening to reduce losses.The fourth chapter reviews existing research in the preservation of fruit quality and reduction of post-harvest damage and loss by adopting suitable technologies and knowledge during post-harvest operation, storage management, transportation and marketing of mango fruit.The final chapter explores the advantages and disadvantages of cultivating ripening-impaired tomato mutants. It describes how controlling tomato diseases in both pre- and postharvest operations can help avoid fruit losses.

This collection features four peer-reviewed reviews on improving the shelf life of horticultural produce.The first chapter introduces the concept of smart distribution and highlights how optimising the management of produce distribution systems can reduce loss and waste in the horticultural sector and extend shelf life by minimising quality deterioration. The chapter also discusses the use of remote sensing technology to determine food quality.The second chapter reviews a selection of pre- and postharvest strategies used to optimise fruit quality. The chapter considers ways of measuring harvest maturity, as well as the role of temperature controlled environments in extending the shelf life of tree fruit.The third chapter summarises the wealth of recent research on the preservation of fruit quality in mango production, as well as how postharvest operations can be optimised to reduce loss and waste and maximise shelf life, including the use of controlled environments, waxes and edible coatings.The final chapter explores the advantages and disadvantages of cultivating ripening-impaired tomato mutants and genetically engineered genotypes characterized by inhibition of the ripening process. The chapter considers the use of ethylene inhibitors and controlled environments as a means of mitigating devastating yield losses.

ECG Self-Study Book is a practical guide to help trainees interpret ECGs and recognise cardiac abnormalities. Divided into thirty sections, each part describes twelve cases illustrating a related set of abnormalities seen in different heart diseases, along with their interpretation.The book presents 400 practice ECG tracings, with explanations and diagnoses for reference. Key features of each tracing, logic behind the ECG findings and their clinical relevance are emphasised to help understanding. Many cases include multiple choice questions or require trainees to draw a ladder diagram for practice.Written by internationally recognised Professor K Wang from the University of Minnesota, this book is an invaluable reference to help trainees learn and practise accurate interpretation of ECG findings and correlate them with clinical diagnosis.Key pointsPractical guide to help trainees interpret ECGs and recognise cardiac abnormalitiesPresents 400 practice ECG tracings with detailed explanations and diagnosesMultiple choice questions and ladder diagram drawing practice included in many casesAuthored by internationally recognised Prof K Wang from University of Minnesota
