The team used data collected in the area surrounding Tanzania's largest city, Dar es Salaam, to see how far the degradation "waves" had travelled between 1991 and 2005.
The fear is that the impacts of climate change in the form of droughts, famines, floods, variability in rainfall, storms, coastal inundation, ecosystem degradation, heat waves, fires and epidemics will undermine the international efforts to combat poverty (HDR 2008).
In this context, an experimental damage analysis strategy is proposed here that combines crack density measurements, acoustic emission analysis and optical microscopy with the recording of stiffness degradation by ultrasonic wave speed measurements.
Eggs are lost from spawning grounds via consumption by predators and scavengers, removal by wind and waves, degradation, and other mechanisms.
However, it is reasonable to say that some degradation of the surface wave velocity (about 10%%) across a surface-breaking crack is evidence of a deep crack, comparable to the wavelength of surface waves.
Therefore, it is reasonable to say that some degradation of the surface wave velocity (about 10%%) across a surface-breaking crack is evidence of a deep crack, compared to the wavelength of surface waves.
The automatic recognition of MP3 compressed speech presents a challenge to the current systems due to the lossy nature of compression which causes irreversible degradation of the speech wave.
Variations of stiffness degradation, matrix cracking and guided wave velocities caused by finely distributed or accumulated voids are shown.
Thus, the latter condition causes to both the degradation in amplitude of pair wave function (decrease in the overlapping of Cu 3d and O 2p functions) and metastability due to the reduction of hole trap energy.
The discovery of two modes of response has also been shown recently for protein dynamics to a drug perturbation where a rapid translocation of specific proteins and a slower, wide-ranging temporal wave of protein degradation and accumulation occurred [34].
