in an attempt to assess objectively the integrity of the auditory pathways in 30 patients with definite multiple sclerosis (ms), an audiometric evaluation was performed and auditory brainstem responses (abrs) were obtained. stressing the auditory system by increasing the stimulation rate showed some enhancement in the identification of ms. 24 (ro%) patients had an abnormal abr along with clinic...

If the relation between monetary policy and macroeconomic outcomes is uncertain, the private sector has an incentive to scrutinize the past for...

In water-bearing porous rocks, pore pressure variations play a major role in deformation, through dissolution?precipitation and fracturing processes. An often-overlooked variation where falls to negative or tension can operate whenever aquifer formations dry out, for instance, deep storage (nuclear industrial wastes, long-term CO 2 mitigation, short-term energetic resources, etc.). This generat...
