Book Description
Crossing borders - both physically and imaginatively - is part of our 'nomadic' postmodern identity, but transcultural and transnational exchanges have also played a major role in the centuries-long processes of hybridisation that helped to fashion the vast geographic, political and imaginative container of diversity we call Europe. This volume gathers together the work of scholars from several European countries in an attempt to encourage a collective reflection upon historical - and often 'mythical' - locations and landscapes, as well as upon the thresholds and faultlines that unite or separate them. The issues the volume tackles are delicate and complex, for the encounter of differences engenders both curiosity and suspicion and there is no easy way to create a new synthesis while respecting and promoting diversity. However, since Europe is inevitably a cultural and political entity 'in the making', Europeans should embrace the 'great narrative' of a 'utopian project', uniting their efforts to work towards a civilisation that is grounded on plurality and openness.

Book Description
This presentation describes various aspects of the regulation of tissue oxygenation, including the roles of the circulatory system, respiratory system, and blood, the carrier of oxygen within these components of the cardiorespiratory system. The respiratory system takes oxygen from the atmosphere and transports it by diffusion from the air in the alveoli to the blood flowing through the pulmonary capillaries. The cardiovascular system then moves the oxygenated blood from the heart to the microcirculation of the various organs by convection, where oxygen is released from hemoglobin in the red blood cells and moves to the parenchymal cells of each tissue by diffusion. Oxygen that has diffused into cells is then utilized in the mitochondria to produce adenosine triphosphate (ATP), the energy currency of all cells. The mitochondria are able to produce ATP until the oxygen tension or PO2 on the cell surface falls to a critical level of about 4–5 mm Hg. Thus, in order to meet the energetic needs of cells, it is important to maintain a continuous supply of oxygen to the mitochondria at or above the critical PO2 . In order to accomplish this desired outcome, the cardiorespiratory system, including the blood, must be capable of regulation to ensure survival of all tissues under a wide range of circumstances. The purpose of this presentation is to provide basic information about the operation and regulation of the cardiovascular and respiratory systems, as well as the properties of the blood and parenchymal cells, so that a fundamental understanding of the regulation of tissue oxygenation is achieved.

Book Description
The partition of fluid between the vascular and interstitial compartments is regulated by forces (hydrostatic and oncotic) operating across the microvascular walls and the surface areas of permeable structures comprising the endothelial barrier to fluid and solute exchange, as well as within the extracellular matrix and lymphatics. In addition to its role in the regulation of vascular volume, transcapillary fluid filtration also allows for continuous turnover of water bathing tissue cells, providing the medium for diffusional flux of oxygen and nutrients required for cellular metabolism and removal of metabolic byproducts. Transendothelial volume flow has also been shown to influence vascular smooth muscle tone in arterioles, hydraulic conductivity in capillaries, and neutrophil transmigration across postcapillary venules, while the flow of this filtrate through the interstitial spaces functions to modify the activities of parenchymal, resident tissue, and metastasizing tumor cells. Likewise, the flow of lymph, which is driven by capillary filtration, is important for the transport of immune and tumor cells, antigen delivery to lymph nodes, and for return of filtered fluid and extravasated proteins to the blood. Given this background, the aims of this treatise are to summarize our current understanding of the factors involved in the regulation of transcapillary fluid movement, how fluid movements across the endothelial barrier and through the interstitium and lymphatic vessels influence cell function and behavior, and the pathophysiology of edema formation.

Book Description
This volume addresses the interface of two major national problems: the epidemic of HIV-AIDS and the widespread use of illegal injection drugs. Should communities have the option of giving drug users sterile needles or bleach for cleaning needs in order to reduce the spread of HIV? Does needle distribution worsen the drug problem, as opponents of such programs argue? Do they reduce the spread of other serious diseases, such as hepatitis? Do they result in more used needles being carelessly discarded in the community? The panel takes a critical look at the available data on needle exchange and bleach distribution programs, reaches conclusions about their efficacy, and offers concrete recommendations for public policy to reduce the spread of HIV/AIDS. The book includes current knowledge about the epidemiologies of HIV/AIDS and injection drug use; characteristics of needle exchange and bleach distribution programs and views on those programs from diverse community groups; and a discussion of laws designed to control possession of needles, their impact on needle sharing among injection drug users, and their implications for needle exchange programs.

Book Description
In the era of the Anthropocene, site matters are more pressing than ever. Building on the concepts, theories, and multi-disciplinary approaches raised in the first edition, this publication strives to address the changes that have taken place over the last 15 years with new material to complement and re-position the initial volume. Reaching across design disciplines, this highly illustrated anthology assembles essays from architects, landscape architects, urban designers, planners, historians, and artists to explore ways to physically and conceptually engage site. Thoughtful discourse and empirically grounded pieces combine to provide the language and theory to contextualize the meanings of site in the built environment. The increasingly complex hybridity of constructed environments today demands new tools for thinking about and working with site. Drawing contributions from outside and within the traditional design disciplines, this edition will trace important developments in site thinking with new essays on topics such as climate change, landscape as infrastructure, shifts from global to planetary urbanization debates, and the proliferation of participatory site transformation practices. Edited by two leading practitioners and academics, Site Matters juxtaposes timeless contributions from individuals including Elizabeth Meyer, Robert Beauregard, and Robin Dripps with original new writings from Peter Marcuse, Jane Wolff, Neil Brenner, and Thaisa Way, amongst others, to recontextualize and reignite the debate around site. An ideal text for students, academics, and researchers interested in site and design theory.
