The tests were carried out in two stages: at the first stage, height of fall load was assumed to be insignificant, which did not lead destruction structure, while its deformation considered elastic stage work materials; second selected based on condition bringing structure destruction, elastic-plastic studied.
This study reviews seismograms from 10 rock-fall events recorded between 1992 and 2001 by the permanent seismological network Sismalp in the French Alps. A new seismic magnitude scale was defined, which allowed us to compare and classify ground-motion vibrations generated by these Alpine rock-falls. Each rock-fall has also been characterized by its ground-motion duration t30 at an epicentral di...
BACKGROUND Frailty is associated with adverse outcomes including disability, mortality and risk of falls. Trauma registries capture a broad range of injuries. However, frail patients who fall comprise a large proportion of the injuries occurring in ageing populations and are likely to have different outcomes compared to non-frail injured patients. The effect of frail fallers on mortality is und...
learning a second or foreign language requires the manipulation of four main skills, namely, listening, reading, speaking, and writing which lead to effective communication. it is obvious that vocabulary is an indispensible part of any communication, so without a vocabulary, no meaningful communication can take place and meaningful communication relies heavily on vocabulary. one fundamental fac...
We investigate decaying D-branes as the origin of the thermal string gas of string gas cosmology. We consider initial configurations of low-dimensional branes and argue that they can time evolve to thermal string gas. We find that there is a range in the weak string coupling and fast brane decay time regimes, where the initial configuration could drive the evolution of the dilaton to values, wh...
Comment The fall in differences in height between groups varying in intelligence and educational level is probably attributable to changing social factors,perhaps specifically a greater homogeneity of nutritional conditions across different social classes. In earlier data we found that the social class of parents correlated with the intelligence (0 32) and educational level (0 42) of their chil...
