Macroseismic effects of the principal earthquakes occurring in the United States from 1568 through 1989 are described. Principal earthquakes are defined as those of Modified Mercalli intensity > VI or Richter magnitude > 4.5. Exceptions are the State of Alaska and the offshore areas of California, Oregon, and Washington, where the magnitude cutoff is > 5.5.
В брошюре освещен опыт применения сборного предварительно напряженного железобетона. при строительстве большепролетных конвейерных галерей на заводе железобетонных изделий имени 40-легия Ленинского комсомола в Ленинграде. Приведены сравнительные технико-экономические показатели конструкций галерей и намечены пути дальнейшего внедрения сборного предварительно напряженного железобетона в строительство подобных сооружений.
At the outset of this book, it is important to articulate clearly what we mean by ‘coast’, because the term means different things to different people. For most holidaymakers, the coast is synonymous with the beach. For birdwatchers, the coast generally refers to the intertidal zone; while for cartographers, the coast is simply a line on the map separating the land from the sea. Coastal scientists and managers tend to take a broader view.According to our perspective, the coast represents that region of the Earth’s surface that has been affected by coastal processes, i.e. waves and tides, during the Quaternary geological period (the last 2.6M years).
Skutterudites have been the subject of keen scientific studies for the past 40 years or so. The interest was precipitated by the discovery of Prof. Wolfgang Jeitschko and his colleagues (1977), revealing that an open structure of skutterudites typified by two large voids in the unit cell can be filled with foreign species (ions), giving rise to what are called filled skutterudites. Throughout the years, it has been shown that the filling dramatically modifies the physical properties of the original binary form of skutterudites and gives rise to a plethora of fascinating electronic, magnetic, and superconducting characteristics.
