In contrast to the approaches to resource management and preservation of the past decade, a new perspective on environmental problems is emerging. Six major trends in scientific thinking are (i) increased efforts to examine environments In holistic frameworks, (ii) greater attention to life support systems, (iii) enlarged canvass of the range of choices in resource management, (iv) refinement i...

built environment does not “simply appear overnight, like a movie-set springing up on a vacant lot, but has to be produced”.thus, the first point in dealing with such an environment is considered to be the tracing of time in the evaluation of the city and keeping in mind that the whole is more than its parts. the last point becomes naturally understood when the process of city building is p...

linear green infrastructures along rivers and canals serve different functions: green corridors, or ecological network, maintain biological diversity, improve water quality, and provide areas for fauna and flora to grow and thrive. greenways connect people with landscape resources and serve as recreational areasthat are easy to use and accessible to the greatest number of potential human users....

We present optical observations of a ULX in the nearby spiral galaxy IC 342. This variable source has an average X-ray luminosity of some 10 40 erg/s. At the position of the source there is an ionized nebula (the " Tooth ") having huge dimensions (280 x 130 pc), much larger than normal supernova remnants. Our optical spectra reveal highly supersonic expansion velocities and emission line ratios...

A grounded ice sheet fed from the Ross Embayment filled McMurdo Sound at the last glacial maximum (LGM). This sheet deposited the little-weathered Ross Sea drift sheet, with far-traveled Transantarctic Mountains (TAM) erratics, on lower slopes of volcanic islands and peninsulas in the Sound, as well as on coastal forelands along the TAM front. The mapped upper limit of this drift, commonly mark...
