Border environments
No full textOver the past fifteen years, the Centre for Research Architecture at Goldsmiths, University of London, has brought together established and emergent scholars who convene to work with each other and share their ideas and insights. These assemblies have produced a space of critical encounter for developing new investigative methods, expanded spatial practices, and speculative propositions designed to respond to and intervene in the urgent political conditions of our time. This new series invites the reader into this ever-evolving pedagogical context. Each book is organized around a specific spatial issue and brings together a heterogeneous range of materials and contributors.
The first work in the series, Border Environments, explores the entanglement of ecology and migration. It examines the interplay between discriminatory politics, emergent technologies, and bordering practices within the context of (constructed) natures by highlighting a variety of interventions, investigative techniques, visual projects, and modes of witnessing that address the role of both human and more-than-human actors in border struggles. As such, the book is also a provocation that can be used to identify and organize new lines of struggle connecting environmental and mobility justice

The Clinical Benefits of Adding a Third Dimension to Assess the Left Ventricle with Echocardiography
Full text linkThree-dimensional echocardiography is a novel imaging technique based on acquisition and display of volumetric data sets in the beating heart. This permits a comprehensive evaluation of left ventricular (LV) anatomy and function from a single acquisition and expands the diagnostic possibilities of noninvasive cardiology. It provides the possibility of quantitating geometry and function of LV without preestablished assumptions regarding cardiac chamber shape and allows an echocardiographic assessment of the LV that is less operator-dependent and therefore more reproducible. Further developments and improvements for widespread routine applications include higher spatial and temporal resolution to improve image quality, faster acquisition, processing and reconstruction, and fully automated quantitative analysis. At present, three-dimensional echocardiography complements routine 2DE in clinical practice, overcoming some of its limitations and offering additional valuable information that has led to recommending its use for routine assessment of the LV of patients in whom information about LV size and function is critical for their clinical management
Larval morphology of three Afrotropical pit-building antlions of the genus Myrmeleon Linnaeus (Neuroptera, Myrmeleontidae)
No full textThe remarkable diversity of antlions in the Afrotropical region is counterbalanced by the scarce knowledge of their biology and ecology. In particular, their larval stages are largely unknown and the morphology of African pit-building species was never investigated in detail. The larvae of three pit-building species attaining a wide distribution across the whole continent, namely Myrmeleon caliginosus, M. obscurus and M. quinquemaculatus are described, illustrated and compared with congeners for the first time. Moreover, M. caliginosus is reported for the first time from Namibia, notably extending the known range of this antlion, with implications on the taxonomy and the identification of African Myrmeleon species. The larvae of these three species highlight the overall conservative morphology across the whole genus, differing in relatively minor characters such as size, proportions, pattern and chaetotaxy
