The mechanism whereby systole inhibits coronary blood flow was examined. A branch of the left coronary artery was maximally dilated with an adenosine infusion, and the pressure-flow relationship was obtained for beating and arrested states. The pressure-flow curve for the arrested state was shifted toward higher pressures and in the range of pressures above peak ventricular pressure was linear ...

Water users consider the safety of water according to its aesthetic properties, primarily taste and odour. Geosmin (GEO) 2-methylisoborneol (MIB) are most common odour compounds in freshwaters which cause an earthy musty water. Since human nose can detect these concentrations as low 10 ng/L, it is essential monitor drinking waters before consumer complaints produce a timely solution. Therefore,...

In an urban environment, the occlusion of satellite broadcasts varies across space and thus, preplanning for collection of GPS points requires consideration of these obstructions. This paper presents a GIS embedded model (ArcGIS and ArcObjects) for predicting GPS error via modeling PDOP in an urban environment. The "skyview" model predicted PDOP for spatial locations as a function of the percen...

Note: To follow this note and especially to get definitions of concepts as lower catchment basin, FOZ, dual geodesic reconstruction, I STRONGLY recommend to read the following documents available on my Web page (http://cmm.ensmp.fr/~beucher/publi.html): P algorithm, a dramatic enhancement of the waterfal transformation (http://cmm.ensmp.fr/~beucher/publi/P-Algorithm_SB_BM.pdf, in particular, pa...

This paper demonstrates a toolkit for multiple observer siting to maximize their joint viewshed, on high-resolution gridded terrains, up to 2402 × 2402, with the viewsheds’ radii of up to 1000. It shows that approximate (rather than exact) visibility indexes of observers are sufficient for siting multiple observers. It also shows that, when selecting potential observers, geographic dispersion i...

Evidence is reported for balancing selection acting on variation at major histocompatibility complex (MHC) in wild populations of brown trout Salmo trutta. First, variation at an MHC class I (satr-uba)-linked microsatellite locus (mhc1) is retained in small S. trutta populations isolated above waterfalls although variation is lost at neutral microsatellite markers. Second, populations across se...
