Drallströmungen sind faszinierend, weil darin so manches Phänomen auftritt, das sich mit einem konventionellen Verständnis für Fluiddynamik nicht erschließt. Wohingegen bei den meisten Strömungen Druckgradient und Geschwindigkeitsvektor nahezu gleich ausgerichtet sind, weist der Druckgradient bei Drallströmungen eine wesentliche radiale Komponente senkrecht zum Geschwindigkeitsvektor auf, was zu einer energetischen Schichtung der Strömung in radialer Richtung führt. Dies ermöglicht Strömungstransitionen wie das Wirbelaufplatzen, das häufig zur Stabilisierung der Verbrennung in Gasturbinen eingesetzt wird. In Verbrennungssystemen mit einer dem Wirbelaufplatzen unmittelbar vorangehenden Vormischzone kann sich auf Grund der durch die Verbrennung induzierten Dichte- und Druckgradienten das Wirbelaufplatzen und mit ihm die Flamme stromauf in die Vormischzone verlagern -- es kommt zum Flammenrückschlag. In dieser Arbeit wird experimentell untersucht, warum und wie dieser Flammenrückschlag bei verschiedenen Betriebsbedingungen zustande kommt.

"The early to mid-1990s saw a large surge in U.S. cigar consumption, including premium cigars. Based on recent import data, premium cigar use may be increasing, though they currently make up a small percent of the total U.S. cigar market. Premium cigars have also been the subject of legal and regulatory efforts for the past decade. In 1998, the National Cancer Institute undertook a comprehensive review of available knowledge about cigars - the only one to date. The resulting research recommendations have largely not been addressed, and many of the identified information gaps persist. Furthermore, there is no single, consistent definition of premium cigars, making research challenging. In response, the Food and Drug Administration (FDA) and the National Institutes of Health commissioned the National Academies of Sciences, Engineering, and Medicine to convene a committee of experts to address this issue. The resulting report, Premium Cigars: Patterns of Use, Marketing, and Health Effects, includes 13 findings, 24 conclusions, and nine priority research recommendations and assesses the state of evidence on premium cigar characteristics, current patterns of use, marketing and perceptions of the product, and short- long-term health effects" --

This open access book synthesizes current information on wildland fire smoke in the United States, providing a scientific foundation for addressing the production of smoke from wildland fires. This will be increasingly critical as smoke exposure and degraded air quality are expected to increase in extent and severity in a warmer climate. Accurate smoke information is a foundation for helping individuals and communities to effectively mitigate potential smoke impacts from wildfires and prescribed fires. The book documents our current understanding of smoke science for (1) primary physical, chemical, and biological issues related to wildfire and prescribed fire, (2) key social issues, including human health and economic impacts, and (3) current and anticipated management and regulatory issues. Each chapter provides a summary of priorities for future research that provide a roadmap for developing scientific information that can improve smoke and fire management over the next decade.

Molecular Modeling of the Sensitivities of Energetic Materials, Volume 22 introduces experimental aspects, explores the relationships between sensitivity, molecular structure and crystal structure, discusses insights from numerical simulations, and highlights applications of these approaches to the design of new materials. Providing practical guidelines for implementing predictive models and their application to the search for new compounds, this book is an authoritative guide to an exciting field of research that warrants a computer-aided approach for the investigation and design of safe and powerful explosives or propellants.

The combustion properties of organic materials are used to assess their safety specifications. This knowledge is necessary to avoid potentially disastrous fires. The experimental determination of the combustion properties of a new organic compound is laborious and sometimes even impossible. This book describes methods for the determination and prediction of the combustion properties of organic compounds, along with some examples and exercises. This 2nd Edition includes an updated and improved presentation of the applicationnof different new models for reliable prediction of diverse aspects of flammability of organic compounds.

Dark Days at Noon provides a broad history of wildfire in North America, from pre-European contact to the present. Edward Struzik sheds light on what may happen in the future if we do not learn to live with fire as Indigenous people once did, so that we may learn from how we managed fire in the past and apply those lessons in the future.

The book “Community and Family-Focused Public Health and Sustainable Development” was originally published in the renowned International Journal of Environmental Research and Public Health. This Special Issue encompassed novel aspects of applications that are connected with sustainability issues in community and family-focused public health studies. Contributions have a significant impact on solving public health problems at the family and community levels. The Special Issue originally published scientific papers, including review articles, that fell under this Special Issue’s remit and that were relevant to audiences worldwide. Currently, the term “family health” is most commonly to describe mother and child health and reproductive health. It is rare for family health to include the family as an important context for health development and that includes all family members and the family’s social environment. Authors of scientific research covering issues related to the impact of the family and the environment in which the family lives and functions on its members’ health in the present and in the future were encouraged to contribute their work. In addition, we were especially interested in scientific reports on social, economic, and health inequalities in the context of achieving the sustainable development goals.
