Using the Westerbork Synthesis Radio Telescope, we have detected HI 21 cm-line absorption in the Warm Neutral Medium of the Galaxy toward the ex-tragalactic source 3C147. This absorption, at an LSR velocity of –29±4 km s −1 with a full width at half maximum of 53±6 km s −1 , is associated with the Perseus Arm of the Galaxy. The observed optical depth is (1.9±0.2)×10 −3. The estimated spin tempe...

G iven the high prevalence of coronary artery disease in Western countries, selection of the optimal therapeutic strategy for individual cardiac patients has become an issue of utmost costbenefit importance. During the past two decades, large clinical trials have established the respective roles of medical treatment versus coronary artery bypass surgery in the management of patients with corona...

Abstract: Surveys were carried out for chimpanzees, Pan troglodytes schweinfurthii, in the areas of Ntakata (300 km2 between the Mkamba River and the Lubalisi River, 05°45′ –06°15′ S, 30°00′ –30°15′ E), and Kakungu (200 km2 between the Lubalisi River and the sources of the Rubufu River, 05°55′ –06°15′ S, 30°00′ –30°15′ E), Tanzania, during the dry seasons of 2001 and 2003. The predominant veget...

The current global projections of future sea level rise are the basis for developing inundation hazard maps. However, contributions from spatially variable coastal subsidence have generally not been considered in these projections. We use synthetic aperture radar interferometric measurements and global navigation satellite system data to show subsidence rates of less than 2 mm/year along most o...

In 2003, a network for hydrology of the semiarid region (REHISA in Portuguese) was created in Brazil. Since then, experimental watersheds in this region has been providing hydrometeorological data collected in automatic stations. However, the spatial distribution of these gauges might be insufficient to thoroughly understand the hydrological processes occurring in the area. Remotely sensed hydr...

Seasonally severe and persistent hypoxia, or low dissolved oxygen concentration, occurs on the inner- to mid-Louisiana continental shelf to the west of the Mississippi River and Atchafalaya River deltas. The estimated areal extent of bottom dissolved oxygen concentration less than 2 mg L-1 during mid-summer surveys of 1993-2000 reached as high as 16,000 to 20,000 km2. The distribution for a sim...

Cavitation cluster dynamics after the passage of a single pressure wave is studied for different concentrations of artificial cavitation nuclei (30 to 3x10(5) nuclei/ml). With increasing concentration of cavitation nuclei the lifetime of the cavitation cluster is prolonged. Additionally, it is found that the spatial extent of the cluster decreases with higher nuclei concentration. The experimen...

A general geometrical construction for fullerenes of threefold dihedral symmetry is reported and used to Ðnd those 3 , 3h , 3d examples of this symmetry that are without face spirals. The smallest, a 384-atom cage, has its twelve pentagons arranged in 3 three separate crosses of four fully fused rings and has four atoms more than the smallest known non-spirallable fullerene. Another structure, ...
