COVID-19 has placed American higher education at a crossroads. This book is the roadmap. COVID-19 triggered an existential crisis for American higher education. Faced with few safe choices, most colleges and universities switched to remote learning during the 2020 spring semester. The future, however, provides more choices about how institutions can fulfill their mission of teaching and research. But how do we begin to make decisions in an uncertain and shifting environment? In this concise guide, authors Edward J. Maloney and Joshua Kim lay out clear ways colleges and universities can move forward in safe and effective ways. The Low-Density University presents fifteen scenarios for how colleges and universities can address the current crisis from a fully online semester to others with students in residence and in the classroom. How can changing the calendar or shifting to hybrid models of blended classrooms impact teaching, learning, and the college experience? Could we emerge from this crisis with new models that are better and more adapted to today's world? The Low-Density University focuses primarily on teaching and learning, but student life (housing, athletics, health, etc.) are core to the college experience. Can we devise safe and effective ways to preserve the best of that experience? The lessons here extend beyond the classroom. Just as the pandemic will change American higher education, the choices we make now will change what college looks like for generations to come.

Foams are gas filled integral structures in which the gas is finely dispersed throughout acontinuouslyconnected solid phase. The bulk density is usually substantially lower than that of the solid component, and for the foams which form the focus for this book the volume fraction of the gas phase is considerably greater than 0.5 and in most instances in excess of 0.9. Many ofthe materials encountered in every day experience, such as bread, plants and trees, structural materials for buildings, comfort materials for domestic and automotive seating, shock absorbers or car bumpers and materials for noise control, have one thing in common - the cellular nature of their physical structure. Whyare thesestructuressoimportantin the naturaland man-made world? The reasons are both technical and commercial. From a technical viewpoint cellular materials offer: 1. high specific stiffness and strength - making them suitable for structural applications; 2. closeto idealenergymanagement - hencetheir useinthermalandacoustic insulation, vibration damping, acoustic absorption and shock mitigation; and 3. comfort - hence their use for domestic and automotive seating.

Ultimately, the authors make a compelling case not only for this turn to learning but for creating new pathways for nonfaculty learning careers, understanding the limits of professional organizations and social media, and the need to establish this new interdisciplinary field of learning innovation.

Presents all of the key ideas needed to understand, design, implement and analyse iterative-based error correction schemes.

"Low-Density Polyethylene: Properties and Applications examines the rheology of low-density Poly(ethylene)-based systems. Processing this commodity, alone or in combination with different micro/nano-fillers, requires a deep knowledge of its rheological behavior in order to set up the process parameters. Following this, the comprehensive research progress on low-density polyethylene is reviewed, and the mechanisms of low-density polyethylene biodegradation are summarized. Additionally, the effect of microorganisms on low-density polyethylene and products of this degradation with their level of toxicity is discussed. Later, the authors focus on the different types of low-density polyethylene, microorganism-mediated degradation, changes in the physiological properties of low-density polyethylene post degradation and its applications in other fields. The detailed knowledge of preferential sorption is studied in an effort to reveal new information regarding low-density polyethylene properties. Consequently, the usage of low-density polyethylene in membrane separations is promoted"--

The first systematic, quantitative appraisal of power density, offering detailed reviews of power densities of renewable energy flows, fossil fuels, and all common energy uses. “There's no author whose books I look forward to more than Vaclav Smil.” —Bill Gates In this book, Vaclav Smil argues that power density is a key determinant of the nature and dynamics of energy systems. Any understanding of complex energy systems must rely on quantitative measures of many fundamental variables. Power density—the rate of energy flux per unit of area—is an important but largely overlooked measure. Smil provides the first systematic, quantitative appraisal of power density, offering detailed reviews of the power densities of renewable energy flows, fossil fuels, thermal electricity generation, and all common energy uses. Smil shows that careful quantification, critical appraisals, and revealing comparisons of power densities make possible a deeper understanding of the ways we harness, convert, and use energies. Conscientious assessment of power densities, he argues, proves particularly revealing when contrasting the fossil fuel–based energy system with renewable energy conversions. Smil explains that modern civilization has evolved as a direct expression of the high power densities of fossil fuel extraction. He argues that our inevitable (and desirable) move to new energy arrangements involving conversions of lower-density renewable energy sources will require our society—currently dominated by megacities and concentrated industrial production—to undergo a profound spatial restructuring of its energy system.

Allee effects are relevant to biologists who study rarity, and to conservationists and managers who try and protect endangered populations. This book provides an overview of the Allee effect, the mechanisms which drive it and its consequences for population dynamics, evolution and conservation.

In the last few years, advances in studies and research associated with the borderlands and the subsequent cross-border cooperation (CBC) have been increased and introduced all over the globe. Such advances essentially affect the cross-border strategies and policies, processes of border cooperation, and several complex border movements. Moreover, similar scenarios are encountered in ultra-peripheral and remote territories and low-density regions. There are common denominators, such as the limited land, water resources, and overexploitation of tourism, among many other factors, that make these specific territories critical case studies concerning their governance and sustainable development and growth. Analyzing Sustainability in Peripheral, Ultra-Peripheral, and Low-Density Regions investigates activities, processes, and behaviors in light of the new challenges and the desired sustainable development and growth model. It analyzes the dynamics and patterns ongoing in the peripheral, ultra-peripheral, and low-density regions regarding sustainability and the issues that may influence it. Covering topics such as glamping tourism, vegetation quality, and territorial cohesion, this premier reference source is an essential resource for government officials, business executives and managers, community leaders, environmentalists, researchers, and academicians.

This open access book outlines new concepts, development models, governance and implementation processes capable of addressing the challenges of transformative urban regeneration of cities at precinct scale.
