  • The timing of the publication of this book couldn’t be better as we celebrate the 50th anniversary of Charles Elton’s seminal book, The Ecology of Invasions by Animals and Plants. Since this influential book was published in 1958, the study of bioinvasions has developed exponentially, alongside the exponential growth in the magnitude of the invasion problem itself. Today, bioinvasion, a highly complex ecological process and environmental concern, has become a specific branch in ecology and environmental studies, with many disciplines developing within it....

  • Intelligent Image Processing describes the EyeTap technology that allows non-invasive tapping into the human eye through devices built into eyeglass frames. This isn't merely about a computer screen inside eyeglasses, but rather the ability to have a shared telepathic experience among viewers. Written by the developer of the EyeTap principle, this work explores the practical application and far-reaching implications this new technology has for human telecommunications.

  • In this edited volume, global experts in ecology and evolutionary biology explore how theories in ecology elucidate the processes of invasion, while also examining how specific invasions inform ecological theory. This reciprocal benefit is highlighted in a number of scales of organization: population, community and biogeographic. The text describes example invaders in all major groups of organisms and from a number of regions around the globe.

  • The percent literate in the SEC is substantially higher than indicated for the population 60 and over in the 1998 census. This largely reflects a process of cohort succession through which persons who were 54-59 in 1998, and thus not part of the 60+ population at that time, aged into the 60 and over population by 2004 while at the same time some persons who were 60 or over in 1998 died, especially among the oldest age groups. Since literacy was generally increasing over time in Cambodia, the average literacy level of younger cohorts who moved into the...

  • The scope of this book is to demonstrate that we do have an ecosystem theory that can be used to describe ecosystem structure and function. It was previously shown in the book, Integration of Ecosystem Theories: A Pattern (3rd edition, 2002), that the various contributions to systems ecology are consistent and together form a pattern of ecological processes. My book with Yuri Svirezhev, Toward a Thermodynamic Theory of Ecosystems (2004), presented the thermodynamics of this pattern in a mathematical language....

  • If the saturated phenomenon encompasses excessive phenomena, it can also account for extremely empty and poor phenomena. This process of inversion and turnaround between two extremes in perception is certainly due to the ‘negative’ qualities of Marion’s philosophy and of the French phenomenological new wave in general 4 . Poor phenomena become saturated into an equilibrium system between the empty and the full, the excess and the lack.

  • A suite of emerging techniques, known collectively as “molecular imaging,” now offer scientists an unprecedented opportunity to identify, follow, and quantify biologic processes at the cellular level with molecular specificity in intact organisms. For instance, it is now possible to evaluate, with imaging, the distribution, magnitude, and timing of gene expression in genetically altered animals (1–3).

  • The first high-level consultation between UNFPA and WHO in 2002 called for collaboration in health- sector-wide approaches (SWAps), and adequate investment in reproductive health. In 2004, the second high-level consultation recognized the progress made, and identified a need for complementary efforts from both agencies to mainstream SRH in national and international planning processes.

  • Transportation of species to areas outside their native ranges has been a feature of human culture for millennia. During this time such activities have largely been viewed as beneficial or inconsequential. However, it has become increasingly clear that human-caused introductions of alien biota are an ecological disruption whose consequences rival those of better-known insults like chemical pollution, habitat loss, and climate change. Indeed, the irreversible nature of most alien-species introductions makes them less prone to correction than many other ecological problems.

  • Formaldehyde is widely used to manufacture building materials and numerous household products, and is also a by-product of combustion and certain other natural processes. Primary sources include pressed wood products such as particleboard, plywood, and medium density fiberboard (MDF), which is commonly used in flooring, furniture, shelving, cabinetry, paper products, and decorative fabrics and textiles. It also may be used as a biocide in certain paints, coatings, adhesives, and personal care products.

  • The urokinase-type plasminogen activator (uPA) receptor (uPAR) has been implicated in signal transduction and biological processes including cancer metastasis, angiogenesis, cell migration, and wound healing. It is a specific cell surface receptor for its ligand uPA, which catalyzes the formation of plasmin from plasminogen, thereby activating the proteolytic cascade that contributes to the breakdown of extracellular matrix, a key step in cancer metastasis.

  • For many years, under the definition of Communication for Development, FAO has emphasized the critical role that participatory communication plays in involving communities in rural development. Such a commitment to genuine participation requires openness to the different ways of understanding and resolving problems that emerge from the cultural, economic and agroecological realities of the communities involved.

  • Thirty or more years ago, one who stood at the foot of Main Street, Winnipeg, in front of the stone gate leading to the inner court of Fort Garry, and looked up across the river flats, would have seen a procession as picturesque as ever graced the streets of old Quebec--the dog brigades of the Hudson's Bay Company coming in from the winter's hunt. Against the rolling snowdrifts appeared a line, at first grotesquely dwarfed under the mock suns of the eastern sky veiled in a soft frost fog. Then a husky-dog in bells and harness bounced up over the drifts, followed by another and yet...

  • On August 1, 1990, Iraqi troops rolled into Kuwait. During the two weeks prior to the invasion, members of the U.S. intelligence community had monitored the deployment of Iraqi forces, and several of them had concluded that Saddam Hussein intended to invade Kuwait. The intelligence evaluators forwarded their analyses to the top members of George H. W. Bush’s administration, who refused to validate the conclusions until just a few hours before the start of the invasion.

  • Breast cancer cells exhibit excessive proteolysis, which is responsible for extensive extracellular matrix degradation, invasion and metastasis. Besides other proteases, lysosomal cysteine protease cathepsin B has been impli-cated in these processes and the impairment of its intracellular activity was suggested to reduce harmful proteolysis and hence diminish progression of breast tumors.

  • Chlorophyll fluorescence represents an intrinsic signal emitted by plants that can be employed to monitor their physiological state including changes of the photosynthetic apparatus, developmental processes of leaves, state of health, stress events, stress tolerance, and also to detect diseases or nutrient deficiency of plants. In particular, the application of laser induced chlorophyll fluorescence spectroscopy has drawn much attention recently owing to the non-invasive and nondestructive nature of the technique (Svanberg, 1995; Lang & Lichtenthaler, 1991; Chappelle et al., 1984)....
