Accepted as the standard reference work on modern pneumatic and compressed air engineering, the new edition of this handbook has been completely revised, extended and updated to provide essential up-to-date reference material for engineers, designers, consultants and users of fluid systems.
In the course of evolution, a great variety of root systems have learned to overcome the many physical, biochemical and biological problems brought about by soil. This development has made them a fascinating object of scientific study. This volume gives an overview of how roots have adapted to the soil environment and which roles they play in the soil ecosystem. The text describes the form and function of roots, their temporal and spatial distribution, and their turnover rate in various ecosystems. Subsequently, a physiological background is provided for basic functions, such as carbon acquisition, water and solute movement, and for their responses to three major abiotic stresses, i.e. hard soil structure, drought and flooding. The volume concludes with the interactions of roots with other organisms of the complex soil ecosystem, including symbiosis, competition, and the function of roots as a food source.
Charles Darwin has been extensively analysed and written about as a scientist, Victorian, father and husband. However, this is the first book to present a carefully thought out pedagogical approach to learning that is centered on Darwin’s life and scientific practice. The ways in which Darwin developed his scientific ideas, and their far reaching effects, continue to challenge and provoke contemporary teachers and learners, inspiring them to consider both how scientists work and how individual humans ‘read nature’. Darwin-inspired learning, as proposed in this international collection of essays, is an enquiry-based pedagogy, that takes the professional practice of Charles Darwin as its source. Without seeking to idealise the man, Darwin-inspired learning places importance on: • active learning • hands-on enquiry • critical thinking • creativity • argumentation • interdisciplinarity. In an increasingly urbanised world, first-hand observations of living plants and animals are becoming rarer. Indeed, some commentators suggest that such encounters are under threat and children are living in a time of ‘nature-deficit’. Darwin-inspired learning, with its focus on close observation and hands-on enquiry, seeks to re-engage children and young people with the living world through critical and creative thinking modeled on Darwin’s life and science.
This collection of thoughtful, courageous, and honest essays explores the intersections of class background, social status, and "queerness," challenging the often narrow and rigid definition of gay and lesbian community. Queerly Classed highlights the voices of those whose experiences of class-combined with race, ethnicity, gender, ability, and age to explode stereotypes of queers aspiring to assimilate into the mainstream of the American middle class.
As mainstream music consumers wait with baited breath for the next musical upheaval, a small core of tech-savvy individuals are re-shaping the aural landscape without the assurance of being part of any larger movement. Their ideologies and creative approaches differ wildly, but they share a desire to take sound beyond the realm of mere entertainment. Drawing on extensive research into the world of audio extremity, Micro-Bionic includes interviews with William Bennett (Whitehouse), Peter Rehberg (Mego) and Peter Christopherson (Throbbing Gristle/Coil).
