During confined flow of bulk solids in silos some characteristic phenomena can be created, such as: sudden and significant increase of wall stresses, different flow patterns, formation and propagation of wall and interior shear zones, fluctuation of pressures and, strong autogenous dynamic effects.These phenomena have not been described or explained in detail yet. The main intention of the experimental and theoretical research presented in this book is to explain the above mentioned phenomena i...

This book is an update of the first BACC assessment, published in 2008. It offers new and updated scientific findings in regional climate research for the Baltic Sea basin. These include climate changes since the last glaciation (approx. 12,000 years ago), changes in the recent past (the last 200 years), climate projections up until 2100 using state-of-the-art regional climate models and an assessment of climate-change impacts on terrestrial, freshwater and marine ecosystems. There are dedicated...

The CD-ROM uses to a large extent an approach similar to textbooks on this topic, but also applies the possibilities of multimedia. The CD-ROM contains films, animated sequences and various models. The topics are: air circulation, clouds and precipitation, air mass, frontal zone and polar front, cyclones and anticyclones, general atmospheric circulation and climate change. Furthermore, the CD-ROM includes some interactive chapters and a detailed glossary. The main menu is accessible from any app...

The purpose of this book is to help early career professionals in agriculture and natural resources write their research papers for high-quality journals and present their results properly at professional meetings. Different fields have different conventions for writing style such that the authors of the book have found it difficult to recommend to young scientists in these fields a specific book or source material out of the several that are available as the "go to" guide. Writing a scientific...

Dams are constructed for economic development, and their construction involves large investments of money, and natural and human resources. Of the various types of dams constructed around the globe, earth dams are the most common type and constitute the vast majority of dams. When adam fails, it culminates in the sudden release of artificially stored water which, in turn, becomes a potential menace to virtually everything downstream. The dam failure may result in loss of life and property. In re...

Although poor air quality is probably not the hazard that is foremost in peoples' minds as they board planes, it has been a concern for years. Passengers have complained about dry eyes, sore throat, dizziness, headaches, and other symptoms. Flight attendants have repeatedly raised questions about the safety of the air that they breathe. The Airliner Cabin Environment and the Health of Passengers and Crew examines in detail the aircraft environmental control systems, the sources of chemical and...

An introduction to the storms sometimes known as twisters, including how and where they occur, the damage they can do, and some of the worst tornadoes in recorded history.

Mikroplastik ist derzeit ein allgegenwartiges Thema in den Medien und wird daher auch in der Bevoelkerung als umweltrelevante Problematik wahrgenommen. Da jedoch viel Halbwissen zur Meinungsbildung beitragt, bereitet dieses essential den aktuellen Forschungstand auf und stellt ihn allgemein verstandlich dar. Angefangen bei den Grundlagen der Mikroplastikdefinition und den derzeit bekannten Quellen uber bisher nachgewiesene Konzentrationen in der aquatischen Umwelt bis hin zu den Senken wird der...

The latest attempt to summarize the wealth of knowledge now available on geomagnetic phenomena has resulted in this comprehensive multi-volume treatise, with original up-to-date review articles from many distinguished experts. The third volume of this series covers two broad topics--the relevance of the Eatrh's magnetic field for geological studies and the physics of the upper atmosphere.

Prepared for the 2013 National Climate Assessment and a landmark study in terms of its breadth and depth of coverage, this report blends the contributions of 120 experts in climate science, economics, ecology, engineering, geography, hydrology, planning, resources management, and other disciplines to provide the most comprehensive, and understandable, analysis to date about climate and its effects on the people and landscapes of Arizona, California, Colorado, Nevada, New Mexico, and Utah--includ...

Die menschliche Gesellschaft ist durch moderne wissenschaftliche Verfahren der Klimamodellierung in der Lage, Vorhersagen des zukünftigen Klimas zu treffen. Ebenso lassen sich anhand der aktuellen Klimaforschung mögliche menschliche Ursachen für Klimaänderungen ausmachen. Damit wird das Klima im gesellschaftlichen Bewusstsein zur Sphäre menschlicher Handlungsfolgen. Menschliches "Klimahandeln" wird somit notwendig. Dabei berücksichtigt werden muss sowohl die Risikolage durch unwünschbare Klimawi...

What is air? Why is the sky blue? Why do people react favorably to mountain or sea air? How does desert air differ from the air of California's Central Valley? How is air pollution affecting plants and animals? This book is a unique guide to the air we breathe in California. More than a natural history guide, it approaches this fascinating topic by recognizing the overwhelming role played by humans in the story of California's air. In a highly engaging style, David Carle explains daily weather p...

Dieses Buch führt in die Problematik der Grundwassererschliessung ein. Der Autor beschreibt die Probleme und Methoden der Erschliessung und geht auf die Zusammenhänge der Neubildung und Gewinnung von Grundwasser ein. Dem Grundwasserschutz ist ein eigenes Kapitel gewidmet. Im Ausblick skizziert das Buch die Auswirkungen der Grundwassergewinnung und Ansätze zu einer nachhaltigen Wasserwirtschaft.

This book contains a selection of papers that have been prepared for the NATO Advanced Research Workshop on the Economics of Atmospheric Pollution, that took place in Wageningen, The Netherlands, November 1994, hosted by Wageningen Agricultural University and sponsored by NATO Scientific and Environmental Affairs Division. Participants from the USA and a large number of countries in Western, Central and Eastern Europe have participated to discuss the economic aspects of transboundary air polluti...

In November 1988 the "'Third Oberursel Symposium" devoted to the problems of input of pollutions into forest-ecosystems and their effects on plants or soil convened. After several years of intensive research on the effects of pollutions on forest ecosystems it is obvious that not a single specific pollutant can be made responsible but a mixture of several components act together or interact with each other. The contributions of the workshop _ reflect to a large extend the results of research p...

This book provides guidance for the rational design and application of hydraulic grouts, based on a series of specific data (type of masonry, voids' width, targeted strength and durability level, available materials, etc.). To this end, the basic characteristics of a grout, i.e. its injectability (penetrability, fluidity and stability), its strength and durability, are taken into account by means of rational models and quantified expressions of all grout-design parameters. Thus, a holistic, rati...
