Pollution in the Grand Canyon and the Petrified Forest National Park in eastern Arizona is so bad, park officials say, that it has produced deterioration in vegetation.
Functional imaging studies suggest recruitment of prefrontal areas when healthy subjects are asked to concentrate on producing over learned movements (Jueptner et al., 1997), something that produces deterioration in task performance.
However, in case that Chemical Shift Imaging (CSI) is used then a number of issues have to be considered, such as, the long acquisition which can lead to patients' anxiety which is accompanied by head motion producing spectra deterioration, field inhomogeneities that produce large line widths deteriorating the spectra resolution, chemical shift misregistration and outer volume signal bleed [ 17].
Many concrete structures are exposed to high temperatures that produce material deterioration involving stiffness and strength loss.
However, both fuel price increases and modelled policies give rise to higher transport costs, mobility constraints and reduced accessibility, which inevitably lead to a reduction in GDP and employment growth rates, i.e. they produce a deterioration in competitiveness criteria.
However, since excessive DA release seems to cause MD [ 16] and apoptosis [ 44], it could produce additional deterioration of the brain function and morphology after psychotic episodes.
In fact, previous motor skill studies have shown that periods of daytime wake with learning-effector immobilization (negating corresponding limb interference, hence offering the opportunity for consolidation), not only result in the absence of any memory improvement, but can produce learning deteriorations [4], [24].
Docetaxel 75 mg m−2 once every 3 weeks prolongs survival compared to best supportive care (Shepherd et al, 2000) and produces less deterioration of pain and fatigue (Dancey et al, 2004).
