Download or read book Ice Adhesion written by K. L. Mittal and published by John Wiley & Sons. This book was released on 2020-12-15 with total page 704 pages. Available in PDF, EPUB and Kindle. Book excerpt: This unique book presents ways to mitigate the disastrous effects of snow/ice accumulation and discusses the mechanisms of new coatings deicing technologies. The strategies currently used to combat ice accumulation problems involve chemical, mechanical or electrical approaches. These are expensive and labor intensive, and the use of chemicals raises serious environmental concerns. The availability of truly icephobic surfaces or coatings will be a big boon in preventing the devastating effects of ice accumulation. Currently, there is tremendous interest in harnessing nanotechnology in rendering surfaces icephobic or in devising icephobic surface materials and coatings, and all signals indicate that such interest will continue unabated in the future. As the key issue regarding icephobic materials or coatings is their durability, much effort is being spent in developing surface materials or coatings which can be effective over a long period. With the tremendous activity in this arena, there is strong hope that in the not too distant future, durable surface materials or coatings will come to fruition. This book contains 20 chapters by subject matter experts and is divided into three parts— Part 1: Fundamentals of Ice Formation and Characterization; Part 2: Ice Adhesion and Its Measurement; and Part 3: Methods to Mitigate Ice Adhesion. The topics covered include: factors influencing the formation, adhesion and friction of ice; ice nucleation on solid surfaces; physics of ice nucleation and growth on a surface; condensation frosting; defrosting properties of structured surfaces; relationship between surface free energy and ice adhesion to surfaces; metrology of ice adhesion; test methods for quantifying ice adhesion strength to surfaces; interlaboratory studies of ice adhesion strength; mechanisms of surface icing and deicing technologies; icephobicities of superhydrophobic surfaces; anti-icing using microstructured surfaces; icephobic surfaces: features and challenges; bio-inspired anti-icing surface materials; durability of anti-icing coatings; durability of icephobic coatings; bio-inspired icephobic coatings; protection from ice accretion on aircraft; and numerical modeling and its application to inflight icing.

Download or read book Women on Ice written by Miriam Boeri and published by Rutgers University Press. This book was released on 2013-01-15 with total page 255 pages. Available in PDF, EPUB and Kindle. Book excerpt: Methamphetamine (ice, speed, crystal, shard) has been called epidemic in the United States. Yet few communities were ready for increased use of methamphetamine by suburban women. Women on Ice is the first book to study exclusively the lives of women who use the drug and its effects on their families. In-depth interviews with women in the suburban counties of one of the largest metropolitan areas in the U.S. chronicle the details of their initiation into methamphetamine, the turning points into problematic drug use, and for a few, their escape from lives veering out of control. Their life course and drug careers are analyzed in relation to the intersecting influences of social roles, relationships, social/political structures, and political trends. Examining the effects of punitive drug policy, inadequate social services, and looming public health risks, including HIV/AIDS and hepatitis C, the book gives voice to women silenced by shame. Boeri introduces new and developing concepts in the field of addiction studies and proposes policy changes to more broadly implement initiatives that address the problems these women face. She asserts that if we are concerned that the war on drugs is a war on drug users, this book will alert us that it is also a war on suburban families.

Book excerpt: The Alaskan Beaufort Sea: Ecosystems and Environments provides an interdisciplinary view into almost all aspects of the environment, with a detailed survey of the background literature. This book focuses on the Alaskan Beaufort Shelf environment. Organized into four parts encompassing 20 chapters, this book begins with an overview of the characteristics and history of the region in which the research took place and defines the objectives of the studies program. This text then examines the subsynoptic meteorological networks along the Beaufort Sea coast and shelf. Other chapters consider the thermally generated mesoscale effects on surface winds and the orographic mesoscale effects on surface winds. This book discusses as well the phytoplankton associations and relative phytoplankton production in the area between the 20-m depth contour and the edge of the ice in summer. The final chapter deals with the characteristics of the ice cover and oil-ice interactions that will affect cleanup activities after blowout. This book is a valuable resource for scientists and conservationists.

Download or read book Numerical Modelling of Ice Floods in the Ning Meng Reach of the Yellow River Basin written by Chunqing Wang and published by CRC Press. This book was released on 2018-01-29 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Ning-Meng reach of the Yellow River basin is located in the Inner Mongolia region at the Northern part of the Yellow River. Due to the special geographical conditions, the river flow direction is towards the North causing the Ning-Meng reach to freeze up every year in wintertime. Both during the freeze-up and break-up period, unfavourable conditions occur which may cause ice jamming and ice dam formation leading to dike breaching and overtopping of the embankment. Throughout history this has often led to considerable casualties and property loss. Enhanced economic development and human activities in the region have altered the characteristics of the ice regime in recent decades, leading to several ice disasters during freezing or breaking-up periods. The integrated water resources management plan developed by the Yellow River Conservancy Commission (YRCC) outlines the requirements for water regulation in the upper Yellow River during ice flood periods. YRCC is developing measures that not only safeguard against ice floods, but also assure the availability of adequate water resources. These provide the overall requirements for developing an ice regime forecasting system including lead-time prediction and required accuracy. In order to develop such a system, numerical modelling of ice floods is an essential component of current research at the YRCC, together with field observations and laboratory experiments. In order to properly model river ice processes it is necessary to adjust the hydrodynamic equations to account for thermodynamic effects. In this research, hydrological and meteorological data from 1950 to 2010 were used to analyse the characteristics of ice regimes in the past. Also, additional field observations were carried out for ice flood model calibration and validation. By combining meteorological forecasting models with statistical models, a medium to short range air temperature forecasting model for the Ning-Meng reach was established. These results were used to improve ice formation modelling and prolong lead-time prediction. The numerical ice flood model developed in this thesis for the Ning-Meng reach allows better forecasting of the ice regime and improved decision support for upstream reservoir regulation and taking appropriate measures for disaster risk reduction.

This book was released on 2012-12-06 with total page 191 pages. Available in PDF, EPUB and Kindle. Book excerpt: This symposium was held at the l6lst ACS National Meeting, Los Angeles, March/April 1971. It represents a contribution to the discussion of problems connected with the state of water near macromolecules. Some papers are only peripheral to the problem of water structure but may become quite pertinent in specific cases. Questions concerned with water structure, rate of hydration, and similar problems are of importance for biological processes and are still not yet well understood. It is hoped that the papers presented here will be of some help in the clarification of problems in this area. H. H. G.

Download or read book Fish Evolution and Systematics Evidence from Spermatozoa written by Barrie G. M. Jamieson and published by Cambridge University Press. This book was released on 1991-05-23 with total page 335 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this 1991 book, Professor Jamieson masterfully brings together the literature on fish spermatozoa and voluminous work on the evolutionary history of fishes to provide a detailed synthesis of the two fields of fish spermatology and fish systematics. The author begins by considering invertebrate phyla related to the chordates, and goes through the lower chordates and early fishes to the line leading to amphibians and to highest teleosts. His treatment provides a review of fish systematics based on the classical evidence of gross morphology in a cladistic framework and a critical integration of this with information on the degree to which spermatozoa support of conflict with the various hypotheses of relationship. Additionally, Professor Jamieson is joined by Luke K. -P. Leung to give a review of the principles of biological cryopreservation and of the live preservation of fish gametes.

Book excerpt: “A free-wheeling vehicle . . . an unforgettable ride!”—The New York Times Cat’s Cradle is Kurt Vonnegut’s satirical commentary on modern man and his madness. An apocalyptic tale of this planet’s ultimate fate, it features a midget as the protagonist, a complete, original theology created by a calypso singer, and a vision of the future that is at once blackly fatalistic and hilariously funny. A book that left an indelible mark on an entire generation of readers, Cat’s Cradle is one of the twentieth century’s most important works—and Vonnegut at his very best. “[Vonnegut is] an unimitative and inimitable social satirist.”—Harper’s Magazine “Our finest black-humorist . . . We laugh in self-defense.”—Atlantic Monthly

Download or read book Methamphetamine Laboratories written by Paul V. Ardus and published by Nova Science Publishers. This book was released on 2010-12 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: Methamphetamine (meth), a drug with limited medical use and high potential for abuse and addiction, is a subject of widespread concern. Once associated mainly with the West Coast and white, male, blue-collar workers, illicit meth is now used by diverse population groups nation-wide, with concentrations in the West, Southwest, and Midwest. Meth is supplied primarily by clandestine labs in California and Mexico. The drug is relatively simple to make from easily obtained recipes, but access to certain ingredients has become more difficult. Meth production in small, toxic labs (STLs) increased initially due to the successful closure of some "super-labs" (labs capable of making more than 10 pounds of meth in a 24-hour cycle), relative ease of making meth, continuing demand for the drug, and desire for potential wealth and involvement in a criminal underground social activity. Although the greater fraction of meth used and distributed across the nation comes from super-labs, the sheer number of STLs, their geographic diffusion, and their residual impacts have prompted concern across a wide spectrum of the country.

Download or read book The Regulation of Peace River written by Michael Church and published by John Wiley & Sons. This book was released on 2014-12-31 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a comprehensive overview of the first longitudinal study of the downstream response of a major river to the establishment of a large hydropower facility and dams. Peace River, a northward flowing boreal river in northwestern Canada was dammed in 1967 and the book describes the morphological response of the 1200 km downstream channel and the response of riparian vegetation to the change in flow regime over the first forty years of regulated flows. Beginning with a description of the effect of regulation on the flow and sediment regimes of the river, the book proceeds to study changes in downstream channel geometry on the main stem, on the lowermost course of tributaries, and on the hydraulic geometry, the overall morphology of the channel, and riparian vegetation succession. The river is subject to annual freeze-up and break-up, so a chapter is devoted to the ice regime of the river. A chapter compares the effects of two extraordinary post-regulation flood events. The penultimate chapter presents a prediction of the ultimate equilibrium form of the regulated river based on rational regime theory. An online database of all the main observations will provide invaluable material for advanced students of river hydraulics and geomorphology. This book carefully brings together a range of studies that have been previously inaccessible providing a rare and comprehensive analysis of the effects of a big dam on a river, a river that itself represents an example of the kind of system that is likely to receive considerable attention in the future from dam engineers and environmentalists. • An invaluable reference to river scientists, hydroelectric power developers, engineers and environmentalists • Focus on a northward flowing boreal river, a type that holds most of the remaining hydroelectric power potential in the Northern Hemisphere • Exceptional separation of water and sediment sources, permitting study of the isolated effect of manipulating one of the two major governing conditions of river processes and form • Unique example of water regulation and both natural and engineered flood flows • Detailed study of both morphological changes of the channel and of the riparian vegetation • Online data supplement including major data tables and numerous maps. Details of the main observations and provides material for problem study by advanced students of river hydraulics and geomorphology are provided
