Bird's Eye View (bird + eye_view)
Selected AbstractsA Bird's Eye View on the Science of European Law: Structures, Debates and Development Prospects of Basic Research on the Law of the European Union in a German PerspectiveEUROPEAN LAW JOURNAL, Issue 3 2000Armin von Bogdandy First page of article [source] Helicobacter pylori as a class I carcinogen: Physiopathology and management strategiesJOURNAL OF CELLULAR BIOCHEMISTRY, Issue 2 2007Paraskevi Vogiatzi Abstract The gram-negative bacterium Helicobacter pylori is known as a persistent colonizer of the human stomach, and probably less known is that it is also involved in extraintestinal diseases. Public awareness of its contribution in the development of gastric cancer is less than 15 years old. The efficacy of the current therapies based on antibiotics against H. pylori has been limited by difficulties such as antibiotic resistance and recurrence. As a consequence, the development of promising vaccines was prompted as the best preventive measure. Unfortunately, so far vaccines failed the transition from animal models to human trials. This keynote presentation is to provide a bird's eye view of H. pylori -related gastric diseases, including gastric cancer, with a synthesis of the molecular mechanisms involved, and an exhaustive presentation and discussion of the current therapeutic guidelines and future strategies for prevention or therapy.

[source] A bird's eye view of the peppered mothJOURNAL OF EVOLUTIONARY BIOLOGY, Issue 2 2000Majerus Industrial melanism in Biston betularia is one of the best known examples of the role of natural selection in evolution and has received considerable scrutiny for many years. The rise in frequency of the dark form of the moth (carbonaria) and a decrease in the pale form (typica) was the result of differential predation by birds, the melanic form being more cyptic than typica in industrial areas where the tree bark was darkened by air pollution. One important aspect of early work evaluating the relative crypsis of the forms of B. betularia on tree trunks with different lichen flora was the reliance on human observers. Humans, however, do not have the same visual capabilities as birds. Birds have well-developed ultraviolet (UV) vision, an important component of their colour processing system that affects many aspects of behaviour, including prey detection. We examined the UV characteristics of the two forms of B. betularia and a number of foliose and crustose lichens. In human visible light the speckled form typica appeared cyptic when seen against a background of foliose lichen, whereas the dark form carbonaria was conspicuous. Under UV light the situation was reversed. The foliose lichens absorbed UV and appeared dark as did carbonaria. Typica, however, reflected UV and was conspicuous. Against crustose lichens, typica was less visible than carbonaria in both visible and UV light. These findings are considered in relation to the distribution and recolonization of trees by lichens and the resting behaviour of B. betularia. [source] Carbocationic Polymerizations for Profit and FunMACROMOLECULAR SYMPOSIA, Issue 1 2004Ralf M. Peetz Abstract This presentation consists of two largely independent parts: The first åfor Profit, part concerns a bird's eye view of recently commercialized carbocationic processes and materials created by these processes in the author's laboratories whose marketing started during the past ,5 years by various companies. These materials/processes include liquid telechelic polyisobutylene (PIB) for architectural sealants, poly(styrene- b -isobutylene- b -styrene) (PSt- b -PIB- b -PSt) triblocks for thermoplastic elastomers, PIB/PSt-based blocks for coating of medical devices, and PIB-based microemulsions for surface protection of painted metal surfaces. It is concluded that in order to enhance and solidify research in polymer synthesis it would behoove the scientific community to pay increased attention to intellectual property protection. Appropriately managed patenting and publishing activities are self-reinforcing and may be quite profitable. The second "for Fun" part concerns a brief review of the design, synthesis and characterization of two novel fully aliphatic star-block copolymers: ,(PIB- b -PNBD)3 and ,(PNBD- b -PIB)3 (where PNBD = polynorbornadiene). The constituent moieties of these star-blocks are identical except their block sequences are reversed. Motivation for the synthesis of ,(PIB- b -PNBD)3, consisting of a low Tg (,-73°C) PIB inner-corona attached to a high Tg (,320°C) PNBD outer corona, was the expectation that this star-block would exhibit thermoplastic elastomer characteristics, and that it could be used in applications where similar polyaromatic-based TPEs cannot be employed (e.g., magnetic signal storage). The other star-block, ,(PNBD- b -PIB)3, comprises the same building blocks with the PIB and PNBD sequences reversed. We found that the secondary chlorine at the PNBD chain end, in conjunction with TiCl4, is able to initiate the polymerization of isobutylene. Details of the carbocationic polymerization of NBD, together with the microstructure of PNBD, will be discussed. [source] Of eagles and flies: orientations toward the siteAREA, Issue 3 2010Keith Woodward The macro-micro distinction is one of the most powerful in the human and physical sciences. In this article we challenge the macro by positing an alternative that recognises the intricacies and complexities of material geographies. We employ the Latin proverb , Aquila non captat muscas (Eagles don't catch flies) , to epitomise our position. Instead of looking to general theory , the bird's eye view , we argue for interrogating the ontological and methodological implications of a reciprocal, but antithetical, perspective , that of the flies. We call this alternative the site, an ontology that attempts to account for the different and varying political possibilities , virtually infinite and ,un-catalogue-able', constantly at work in the world. The site is a formulation that recognises social life as a realm of infinite singularity and variability, where matter is immanently self-organising and pure difference unfolds. We explore the spatiality of the site through the concepts of topology and difference and then develop four methodological orientations for exploring the terrain of situated practices enmeshed in and unfolding through sites.
