[1] Building on previously published details of the laboratory calibrations of the Harvard Lyman-a photofragment fluorescence hygrometer (HWV) on the NASA ER-2 and WB-57 aircraft, we describe here the validation process for HWV, which includes laboratory calibrations and intercomparisons with other Harvard water vapor instruments at water vapor mixing ratios from 0 to 10 ppmv, followed by in-fl...

Several physical as well as numerical experiments have shown that a fluid flowing between two parallel plates can be significantly influenced by the shape of the boundary. In particular, the presence of microscopic asperities parallel to the flow (riblets) can considerably reduce the drag experienced by the fluid (see Chu and Karniadakis [7], Savill et al. [11]). The main objective of the prese...

BACKGROUND Nitric oxide (NO), in addition to its potent vasorelaxant properties, may participate in growth regulation of cultured smooth muscle cells. It was recently demonstrated that in vivo endothelial injury induces the production of NO from L-arginine in the arterial wall. METHODS AND RESULTS We studied the effects of long-term administration of L-arginine, the precursor of NO, on neoint...

STUDY OBJECTIVE To test the relative efficiency of balloon-tipped and plain catheters for aspiration of venous air embolism. DESIGN The following four single-lumen central venous catheters were studied in a silastic model of the right atrium, tricuspid valve, and vena cavae: (1) the 16-gauge single-orifice catheter; (2) the 14-gauge Bunegin-Albin multiorifice catheter; (3) the 7-Fr pulmonary ...

Abstract This work presents the demonstration of a plastic optical fiber (POF)-based ammonia sensor. The sensor head is formed by bending an unclad optic into balloon-like structure. radius bent varied from 1.0 to 2.5 cm. performance each tested using solution with concentration ranging 0 15 mg/L. Results show that optimized performances proposed occur when fixed at 1.5 At this radius, illustra...
