The Selfish Cell : An Evolutionary Defeat

almost half a century ago. Today, after so many years of feverish research and uncountable efforts worldwide, the end of the war appears far as ever, whereas the fight is leading researchers to newer and newer battlefronts while frontiers in bioscience are continuously being surpassed. In this scenario, “The Selfish Cell” is a script record of the most important strategic points gathered during these years of war, with the goal to provide solid ground onto which to step ahead for future assaults against this terrible disease. At the same time, it is an attempt to shift the debate on cancer toward a more peaceful and possibly productive semantic terrain, where to reflect with the aid of superior wisdom to finally get out of that terrible chaos of fight and death dominating our days. In this perspective, “The selfish cell” becomes an occasion for reflecting the limits of our human selfishness and their consequences on both our social and natural environment.

Stress ribbon and cable-supported pedestrian bridges

Stress-ribbon bridges' is the term used to describe structures formed by a very slender concrete deck in the shape of a catenary. They can be designed with one or more spans and are characterized by successive and complementary smooth curves. These curves blend into the natural environment and their forms, the most simple and basic of structural solutions, clearly articulate the flow of internal forces which can be erected without undue pressure on the environment. Stress Ribbon and Cable-supported Pedestrian Bridges looks at how slender concrete deck are used in the design of suspension and cable stayed structures.

Photomorphogenesis in plants and bacteria : Function and signal transduction mechanisms

Plants as sessile organisms have evolved fascinating capacities to adapt to changes in their natural environment. Arguably, light is by far the most important and variable environmental factor. The quality, quantity, direction and duration of light is monitored by a series of photoreceptors covering spectral information from UVB to near infrared. The response of the plants to light is called photomorphogenesis and it is regulated by the concerted action of photoreceptors. The combined techniques of action spectroscopy and biochemistry allowed one of the important photoreceptors – phytochrome – to be identified in the middle of the last century.

PET Chemistry : The Driving Force in Molecular Imaging

Molecular imaging (MI) is based on the selective and specific interaction of a molecular probe with a biological target which is visualized through nuclear, magnetic resonance, near infrared or other methods. Therefore it is the method of choice for patient selection and therapy monitoring as well as for specific e- point monitoring in modern drug development. PET (positron emitting tomography), a nuclear medical imaging modality, is ideally suited to produce three-dimensional images of various targets or processes. The rapidly increasing demand for highly selective probes for MI strongly pushes the development of new PET tracers and PET chemistry. ‘PET chemistry’ can be de?ned as the study of positron-emitting compounds regarding their synthesis, structure, composition, reactivity, nuclear properties and processes and their properties in natural and - natural environments.

Numerical partial differential equations for environmental scientists and engineers : A first practical course

This book concerns the practical solution of Partial Differential Equations (PDEs). It reflects an interdisciplinary approach to problems occurring in natural environmental media: the hydrosphere, atmosphere, cryosphere, lithosphere, biosphere and ionosphere. It assumes the reader has gained some intuitive knowledge of PDE solution properties and now wants to solve some for real, in the context of practical problems arising in real situations. The practical aspect of this book is the infused focus on computation. It presents two major discretization methods - Finite Difference and Finite Element. The blend of theory, analysis, and implementation practicality supports solving and understanding complicated problems. It is divided into three parts. Part I is an overview of Finite Difference Methods. Part II focuses on Finite Element Methods, including an FEM tutorial. Part III deals with Inverse Methods, introducing formal approaches to practical problems which are ill-posed.

Mathematics and Mechanics of Granular Materials

Granular or particulate materials arise in almost every aspect of our lives, including many familiar materials such as tea, coffee, sugar, sand, cement and powders. At some stage almost every industrial process involves a particulate material, and it is usually the cause of the disruption to the smooth running of the process. In the natural environment, understanding the behaviour of particulate materials is vital in many geophysical processes such as earthquakes, landslides and avalanches. This book is a collection of current research from some of the major contributors in the topic of modelling the behaviour of granular materials. Papers from every area of current activity are included, such as theoretical, numerical, engineering and computational approaches. This book illustrates the numerous diverse approaches to one of the outstanding problems of modern continuum mechanics.

International conference on terrain and geohazard challenges facing onshore oil and gas pipelines : Evaluation, routing, resign, construction, operation ; Proceedings of a three day international conference on terrain and geohazard challenges facing onshore oil and gas pipelines, organised by the Institution of Civil Engineers in association with BP Exploration and held at the Institution of Civil Engineers, London, UK, on 2 – 4 June 2004

To access global oil and gas deposits, major pipelines must traverse remote regions with extreme terrains. There are a significant number of pipeline projects, active or planned, in tropical jungles, mountains and deserts, in permafrost and in areas of wetland. Each of these natural environments is associated with a range of geohazards, which may include landslides, soil erosion, karst, river migration, and seismic or volcanic activity. At the same time, society demands increasing availability and reliability of supply, together with improved environmental standards, all making for substantial challenges.

Environmental Risk Assessment : Quantitative Measures, Anthropogenic Influences, Human Impact

The world is a dirty place and getting dirtier all the time. The reasons for this ever-increasing lack of cleanliness are not hard to find, being basically caused by the actions of the six billion people who inhabit the planet. The needs of the people for air, water, food, housing, clothing, heating, materials, oil, gas, minerals, metals, chemicals, and so forth have, over the centuries, given rise to a variety of environmental problems that have been exacerbated or been newly created by the industrialization of the world, the increase in population, and the increase in longevity of the population. The costs of cleaning even fractions of the known environmental problems are truly enormous, as detailed in the volume Environmental Risk Analysis (I. Lerche and E. Paleologos, 2001, McGraw-Hill). The chances of causing new environmental problems, and their associated costs of clean up, are equally challenging in terms of anthropogenic influences and also of the natural environmental problems that can be triggered by humanity.

Environmental Geology : Handbook of Field Methods and Case Studies

As earth’s population continues to grow and the detrimental aftereffects of industrialization and environmental negligence become more apparent, society has become more aware of, and concerned about, stewardship of the natural environment – water, soil, and air. Sustainable development has become more widely received and promoted in many parts of the world. The need is now critical for earth and environmental scientists and engineers to work together to implement technologies that can preserve our environment. The Earth’s population was 6.6 billion as of April 2007 according to the U.S. Census Bureau. This number is expected to rise to 9.4 billion by 2050. The population is increasing the demand for natural resources and energy, and increasing stress on the environment. Thus, protection of the environment and remediation of damage to the environment must be a priority. It is also important to develop procedures that will help to avert further damage to the environment and to recognize as early as possible the risks associated with changes in the environment. Many methodologies and technologies have become more advanced in the past few decades, and new technologies and approaches have been developed, all to address the growing need for environmental assessment, monitoring, and remediation. As these technologies have grown, the need for interdisciplinary cooperation has also become more apparent.
