    Before parting with Babylon, I will give a short sketch of its history. Babylon is said to have existed before the Flood, and in the Book of. Genesis it is given as the site of the tower. The city is first mentioned in the inscriptions of Izdubar at the time when the Babylonian monarchy was being formed by the uniting of a number of little states.

  • Computer modeling of rock fall : improvement and

    Rock falls are a common hazard affecting people and infrastructure below natural cliffs and in man-made environments such as roads, railways, quarries and open pit mines. Computer models have become standard in assessing the hazards posed by rock falls, and there are a wide variety of models currently available. The main difference between these models is the way in which they represent the

    The purpose of our excavations was to expose the Bělka tuff bed and to study carefully its plant fossil content to obtain data for palaeoecological reconstruction of the buried plant assemblage. Therefore, between 1.5 and 2.5 m thick overburden composed of the Brousek Bed was removed down by an excavator to a level just above the Bělka Bed.
