Available Language: English, Spanish, And French
EBOOK SYNOPSIS:

Oceans and lakes are characterized by large residence times and can thus be considered as being in an equilibrium or quasi-equilibrium state. In contrast, estuaries, which constitute the interface between the fresh water and marine ecosystems, are biogeochemically and physically very dynamic. Strong gradients in physical and chemical variables such as temperature, pH, salinity, dissolved oxygen, nutrients, amount and composition of particulates result from the mixing of fresh water and saline end members. These gradients provoke increased biogeochemical processes, generally resulting in a geochemical filter (the area of high turbidity, showing enhanced adsorption-desorption processes) and a biological filter (the area of high plankton activity showing, besides a high uptake of nutrients, a high accumulation of trace metals). Both filters disturb the conservative mixing pattern of the trace metals in an estuary. In addition, four aspects make the Scheldt estuary very unusual and different from other estuaries: the Scheldt is a tide-governed estuary which means larger residence times; the upper estuary receives large inputs of biodegradable organic matter which leads to oxygen depletion in winter and to anoxic conditions in summer; inputs of toxic pollutants occur in the upper estuary by the industrial park of Antwerp; the anoxic zone, the zone of pollutant input and the zone of the turbidity maximum coincide geographically. The Scheldt estuary is thus an ideal field laboratory for the study of biogeochemical processes which do not occur elsewhere, or only partially, to a very low extent or in a specific compartment, i.e. the sediments. More specifically, redox processes involving trace metals, the formation of non-labile metal complexes, and the methylation of mercury occur as a result of anoxic conditions and the high load of organic matter. Several models describing in detail the transport, the sedimentation and the speciation of the trace metals in this well-mixed estuary (all major estuaries in EC countries adjacent to the North Sea or the Atlantic Ocean are well-mixed) are presented in this book. A comparison of the metal concentrations over a 15-year period shows a net reduction of the pollution level.

Conflict And Cooperation On The Scheldt River Basin
Author: S.V. Meijerink
Publisher: Springer Science & Business Media
Release Date: 2012-12-06
Pages: 361
ISBN:
Available Language: English, Spanish, And French
EBOOK SYNOPSIS:

More than 200 major river basins are shared by two or more countries and, together, these basins account for about 60% of the earth's land area, constituting a significant portion of the world's fresh water resources. They are thus both a significant asset to the nations sharing them, as well as a potential source of conflict. This book presents a generic framework for the analysis of decision making on international river issues. It emphasises the strategic character of the interactions between the basin states and addresses learning and institutionalization processes, taking account of the influence of the context on the decision making process. The case of the river Scheldt covers negotiations on the Belgian-Dutch water conventions covering a number of international issues relating to the river basins of the Scheldt and the Meuse, such as construction projects aimed at improving the maritime access to the port of Antwerp, the maintenance of the navigation channel in the Western Scheldt, pollution of the waters in the two rivers, and the distribution of water from the Meuse. The final part of the book contains a typology of strategies for the solution of upstream-downstream problems in international river basins. Audience: All those interested in international water and environmental management, international negotiations and politics, and public policy.

Major Biological Processes In European Tidal Estuaries

Available Language: English, Spanish, And French
EBOOK SYNOPSIS:

This book presents results of the project `Major Biological Processes in European Tidal Estuaries', funded by the Commission of the European Communities under its Marine Science and Technology Programme. This was one of the first projects in which a large number of European macrotidal estuaries, from the Elbe to the Tagus, were studied simultaneously and compared in a coherent way by application of a standardized methodology. It revealed that these estuaries have many species in common and that their ecology can be understood on the basis of a common concept. A major result of the comparison is that, while salinity gradients explain species succession very well within each estuary, similar succession series are found at different salinity levels in different estuaries. Organic loading and the availability of food may explain these differences. Overall, organic loading appears more important in explaining the functioning of tidal estuarine systems than nutrient loading.

Salt Intrusion  Tides And Mixing In Multi Channel Estuaries

EBOOK SYNOPSIS:

Multi-channel estuaries, such as the Mekong Delta in Vietnam and the Scheldt in the Netherlands, have characteristics of both the river and the sea, forming a unique environment influenced by tidal movements of the sea and freshwater flow of the river. This study addresses a number of knowledge gaps in multi-channel estuaries by developing a predictive analytical approach for salinity intrusion and discharge estimate in multi-channel estuaries. The new approach agrees well with 1-D hydrodynamic models and observations, indicating its applicability in practice. Most importantly, the study has successfully developed a new theory and a new equation to quantify tidal pumping due to ebb-flood channel residual circulation and the related salt dispersion.

Attack On The Scheldt

Available Language: English, Spanish, And French
EBOOK SYNOPSIS:

During the Allied advance across northwest Europe in 1944, the opening up of the key port of Antwerp was a pivotal event, yet it has been neglected in histories of the conflict. The battles in Normandy and on the German frontier have been studied often and in detail, while the fight for the Scheldt estuary, Walcheren and Antwerp itself has been treated as a sideshow. Graham Thomas s timely and graphic account underlines the importance of this aspect of the Allied campaign and offers a fascinating insight into a complex combined-arms operation late in the Second World War. Using operational reports and vivid firsthand eyewitness testimony, he takes the reader alongside 21 Army Group as it cleared the Channel ports of Calais, Boulogne and Dunkirk, then moved on to attack the Scheldt and the island stronghold of Walcheren. Overcoming entrenched German resistance there was essential to the whole operation, and it is the climax of his absorbing narrative."

EBOOK SYNOPSIS:

Bridging Boundaries: Making Scale Choices in Multi-Actor Policy Analysis on Water Management synthesizes different perspectives on scale choices (spatial boundary setting, temporal boundary setting and selection of level of aggregation) in policy analysis. Scale choices influence the content of a study (the problems on the agenda, the options found and the impacts addressed) and the process (actors involved, their dedication and criticalness). Scale choices are not politically neutral: they may have advantages or disadvantages for certain actors by putting their urgent problems and their preferred options on the agenda, while they may hide or stress positive or negative impacts of options. Yet, little is known about the specific effects of scale choices and how they are made in practice. In this research, the making of scale choices is studied in two cases in practice: the Long Term Vision Study of the Scheldt Estuary and the Water Shortage Study of the Netherlands. Scale choices appear to be an important framing instrument that can be used by the policy analyst.

Pollution Of The North Sea

Pages: 687
ISBN:
Available Language: English, Spanish, And French
EBOOK SYNOPSIS:

This preface is being written at a time of exceptional public interest in the North Sea, following media head lines on toxic algal blooms, the mass mortality of common seals, and concern over pollution levels. These headlines may suggest that pollution of the North Sea is a recent event. This is not the case. Although no data are available (methods simply did not exist), it is safe to assume that emission (both into air and water) of heavy metals already started to increase in the 19th cen tury. The growth of cities and introduction of sewer sys tems led to the discharge of raw sewage and sewage sludge. The introduction of man-made (xenobiotic) organ ic chemicals and their subsequent emission into the North Sea commenced before the second world war. The shallower and coastal areas of the North Sea receive the highest concentrations of these pollutants. Not unexpectedly, these areas - some Norwegian fjords, the Dutch coast, the German Bight - show signs of ecosystem deterioration and eutrophication. A certain percentage of the pollutants does not remain in the North Sea but is "exported" to the Atlantic. The North Sea therefore con tributes to the global input of pollutants to the world's oceans. The major part of the pollutants accumulate in the North Sea and are incorporated in the bottom sediments. Although they are "out of sight", they should not be "out of mind".

Impact Of Intertidal Area Characteristics On Estuarine Tidal Hydrodynamics  A Modelling Study For The Scheldt Estuary

EBOOK SYNOPSIS:

Abstract: Marsh restoration projects are nowadays being implemented as ecosystem-based strategies to reduce flood risks and to restore intertidal habitat along estuaries. Changes in estuarine tidal hydrodynamics are expected along with such intertidal area changes. A validated hydrodynamic model of the Scheldt Estuary is used to gain fundamental insights in the role of intertidal area characteristics on tidal hydrodynamics and tidal asymmetry in particular through several geomorphological scenarios in which intertidal area elevation and location along the estuary is varied. Model results indicate that the location of intertidal areas and their storage volume relative to the local tidal prism determine the intensity and reach along the estuary over which tidal hydrodynamics are affected. Our model results also suggest that intertidal storage areas that are located within the main estuarine channel system, and hence are part of the flow-carrying part of the estuary, may affect tidal hydrodynamics differently than intertidal areas that are side-basins of the main estuarine channel, and hence only contribute little to the flow-carrying cross-section of the estuary. If tidal flats contribute to the channel cross-section and exert frictional effects on the tidal propagation, the elevation of intertidal flats influences the magnitude and direction of tidal asymmetry along estuarine channels. Ebb-dominance is most strongly enhanced if tidal flats are around mean sea level or slightly above. Conversely, flood-dominance is enhanced if the tidal flats are situated low in the tidal frame. For intertidal storage areas at specific locations besides the main channel, flood-dominance in the estuary channel peaks in the vicinity of those areas and generally reduces upstream and downstream compared to a reference scenario. Finally, the model results indicate an along-estuary varying impact on the tidal prism as a result of adding intertidal storage at a specific location. In addition to known effects of tidal prism decrease upstream and tidal prism increase downstream of additional storage areas, our model results indicate a reduction in tidal prism far downstream of intertidal storage areas as a result of a decreasing tidal range. This study may assist estuarine managers in assessing the impact of marsh restoration and managed shoreline realignment projects, as well as with the morphological management of estuaries through dredging and disposal of sediment on intertidal areas.

EBOOK SYNOPSIS:

Acclaimed historian John C. McManus, author of The Dead and Those About to Die, explores World War II’s most ambitious invasion, Operation Market Garden, an immense, daring offensive to defeat Nazi Germany before the end of 1944. “A riveting and deeply moving story of uncommon courage.”—Alex Kershaw, New York Times bestselling author of The First Wave August 1944 saw the Allies achieve more significant victories than in any other month over the course of the war. The Germans were in disarray, overwhelmed on all fronts. Rumors swirled that the war would soon be over. On September 17, the largest airborne drop in military history commenced over Holland—including two entire American divisions, the 101st and the 82nd. Their mission was to secure key bridges at such places as Son, Eindhoven, Grave, and Nijmegen until British armored forces could relieve them. The Germans, however, proved much stronger than the Allies anticipated. In eight days of ferocious combat, they mauled the airborne, stymied the tanks, and prevented the Allies from crossing the Rhine. September Hope conveys the American perspective like never before, through a vast array of new sources and countless personal interviews to create a truly revealing portrait of this searing human drama.

Applications Of Mass Spectrometry In Life Safety
Author: Crisan Popescu
Publisher: Springer Science & Business Media
Release Date: 2008-09-02
Pages: 238
ISBN:
Available Language: English, Spanish, And French
EBOOK SYNOPSIS:

Mass spectrometry (MS) along with its hyphenated techniques is capable of high throughput, sensitivity, accuracy and selectivity for the analysis of structure and composition of almost any product. Like in electrophoresis, MS separates mo- cules based on the mass-to-charge ratio. In case of gel electrophoresis (SDS- PAGE), a well-known and efficient bioanalytical technique, proteins bear negative charges but have the same charge density, so proteins are separated according to their size. Similarly, in case of MS analysis, proteins carry the same charge, and are separated by their molecular weight. Unlike SDS-PAGE, however, modern ultra high resolution MS discerns very small mass differences and can resolve and completely identify in a single experiment species of the same nominal mass in complex biological mixtures. Consequently, MS can be used for the structural characterization, identification and sensitive detection of mixtures of biomolecules or for assessing the quality of isolated proteins (purity, integrity, or post-translational modifications, for example), carbohydrates, nucleic acids, drugs, metabolites, pollutants etc. In the post-genome era, MS is continuously developing as one of the most re- able analytical method for elucidating the structure of molecules originating from various biological matrices. The potential of MS for high-sensitive structural a- lyses became unsurpassable after the introduction of electrospray (ESI) and matrix assisted laser/desorption ionization (MALDI) methods, on one hand, and the pos- bility to deduce in detail unknown biopolymer structures by highly accurate mo- cular mass measurement followed by sequencing using dissociation techniques based on multiple stage MS, on the other.

EBOOK SYNOPSIS:

Between 1941 and 1944 Waffen-SS Oberscharfôhrer (Sergeant) Werner Kindler took part in 84 days of close combat, qualifying him for the Close Combat Clasp in Gold, the Third Reich's highest decoration for a frontline soldier. He was also awarded the German Cross in Gold, the Iron Cross First and Second Class and the Wound Badge in Gold.??Drafted into the SS-Totenkopf in 1939, he served with a motorised unit in Poland, and in May 1941 was selected for the Leibstandarte-SS Adolf Hitler, with which he fought in the invasion of the Soviet Union. His unit converted to a Panzer Grenadier formation in 1942, and Kindler went on to fight at Kharkov and Kursk on the Eastern Front, and later in Belgium and France in 1944. At the end of the war, he was the last man of the Leibstandarte-SS to surrender to the Americans. This is one of the most dramatic first-hand accounts to come out of the Second World War.
