form ended with the last ice age in Europe, it persisted until very recently in Australia, although examples of twentieth century work are rare and may have been influenced by outsiders. Incredibly, this latest find comprises a continuous historical record from 15,000 years ago to 50 years ago. Thus it is that, alongside ancient depictions of classic rock art images such as human hand outlines,...

STUDY DESIGN Using fresh cadavers, the biomechanical testing were used to examine the pullout strength of each pedicle screw. OBJECTIVE The aim of this study was to evaluate pullout strength of (1) a redirected pedicle screw following lateral wall breach; (2) a redirected pedicle screw following end-plate breach; and (3) a pedicle without redirection after end-plate breach without redirection...

This paper was motivated by the growing data breach activities confronting organizations. Building on the literature on information sharing and network effects, we attempt to empirically examine how the number of security breaches may change as a result of two opposing network effects in the data breach battlefield, namely, the positive network effects driven by industry-wide information sharin...

The restorative potential of dam removal on ecosystem function depends on the reversibility of dam effects and its operations. While dam removal is an established engineering practice, the need for an understanding of the ecological response remains. We used paleoflood hydrology, hydrologic modeling, and aerial photo interpretation to investigate the long-term ecologic responses to dam failure ...

[Abstract] A model of the case breach fault for solid rocket boosters (SRBs) that takes into account burning-through hole in propellant, insulator and metal layers of a rocket case is developed. Melting of the metal layer and an ablation of the insulator layer in the presence of hot gas flow through the hole are analyzed in detail. Dynamics of the lateral (side) thrust produced by the growing h...

In recent years, the intensified influences of global climate change and human activities have increased frequency large-scale debris flow disasters. As a result, main river channels often become blocked, thus forming disaster chain rivers dammed by followed outburst flooding. order to quickly easily reveal dynamic process dam breach, quantitatively predict flood hazard, this study takes Zhouqu...

a non-performance of contract in due date is considered as an actual breach, has sanctions in order to securing interest of the injured party. has foreseeable breach of contract - it is accepted today as an actual breach by different legal systems - the same sanctions of actual breach of contract? in this article suspension of performance of obligations by innocent party and, in some conditions...
