摘要:The ground-based measurements of the Global Positioning System (GPS) allow estimation of the tropospheric delay along the slanted signal paths through the atmosphere. The meteorological exploitation of such slant delay (SD) observations relies on the hypothesis of azimuthal asymm...

摘要:Conclusions In addition to conduct problems, prenatal nicotine exposure may increase the offspring's risk for posttraumatic stress disorder (PTSD). This relationship may be explained, in part, by effects on nicotinic acetylcholine receptors and uteroplacental mechanisms [1].

摘要:Conclusions Migrants report less substance use than the general population, but acculturation-related factors seem to be associated with higher levels of substance use among migrants. Substance use seems to be a gendered phenomenon in migrant populations in comparison to the gene...

摘要:Conclusions High novelty seeking and low persistence are associated with problematic alcohol use among middle-aged Northern Finns. Gender differences in predictors existed: novelty seeking predicted increase only for men in the adjusted model. Temperament scores do not seem to af...

摘要:A number of structural properties of white matter can be assessed in vivo using multimodal magnetic resonance imaging (MRI). We measured profiles of R1 and R2 relaxation rates, myelin water fraction (MWF) and diffusion tensor measures (fractional anisotropy [FA], mean diffus...

摘要:We have examined the relationship of Campylobacter - like organism (CLO) and duodenogastric reflux (DGR) in 107 patients with unoperated stomachs. Neither the extent of externally measured bile reflux nor the concentrations of bile acids or lysolecithin in the gastric fluid diffe...

摘要:The presence of cyanobacteria generally decreased the effectiveness of Bacillus thuringiensis H-14 (BTI) as a mosquito larvicide. The effect was more pronounced when the mosquito larvae were exposed to BTI in the presence of several cyanobacterial strains. No synergistic or ...

摘要:The statistics of cloud-base vertical velocity simulated by the non-hydrostatic mesoscale model AROME are compared with Cloudnet remote sensing observations at two locations: the ARM SGP site in Central Oklahoma, and the DWD observatory at Lindenberg, Germany. The results sh...
