Muddying The Water For A Clear Diagnosis
D65. CASE REPORTS OF UNUSUAL PULMONARY INFECTIONS, 2012Pulmonary sporotrichosis, such as other chronic fungal and mycobacterial infections, can be difficult to diagnose. We present a novel twist on the old technique of bronchoalveolar lavage that leads to improved diagnostic yield.

Starting the cleanup of America's rivers, lakes, and streams was easy. In the 1970s, nearly any action to control pollution yielded improvements in water quality. Now, commercial sources of pollution—those that are readily identified by effluent pipes—are fairly tightly controlled.

Applied Optics, 1973
A parametric analysis is given of imaging in backscattered light in clear ocean water characterized by temperature and salinity inhomogeneities whose scale length is large compared to the diameter of the light beam. An expression for the beam pattern of a finite underwater laser beam is derived where the effects of source coherence on the imaging ...

Since 1978 China's economy has produced economic growth rates making it one of the fastest growing economies. In the same period, China's environment has deteriorated significantly. Rapid urbanization and industrialization have generated enormous volumes of air and water pollutants, lowering air and water quality.

Clear water scour at abutments
Water Management, 2004Laboratory experimental results on local scour at short abutments (abutment length:flow depth ratio ≤ 1), namely vertical-wall, 45° wing-wall and semicircular, in uniform and non-uniform sediments under a clear water scour condition are presented. The equilibrium scour depth is related to the sediment size and approaching flow depth relative to the ...
