in order to determine the effect of valsalva maneuver and head rotation on the internal jugular vein (ijv) diameter and cross-sectional area and overlap with the carotid artery (ca) and find the best technique for safe cannulation of the ijv and decrease the risk of ca puncture, the diameter of both the ijv and the ca and percentage of overlap between the two vessels and cross-sectional area of...

The effect of future climate change is poorly studied in the tropics, especially mountainous areas, yet species living these environments are predicted to be strongly affected. Newly available high-resolution environmental data and statistical methods enable development forecasting models, but uncertainty related models can strong, which lead ineffective conservation actions. Predictive studies...

The genomes of RNA viruses are characterized by their extremely small size and extremely high mutation rates (typically 10 kb and 10(-4)/base/replication cycle, respectively), traits that are thought to be causally linked. One aspect of their small size is the genome compression caused by the use of overlapping genes (where some nucleotides code for two genes). Using a comparative analysis of a...

Some studies of the relationship between continuing bonds and grief intensity have claimed that continuing bonds lead to poor adaptation to bereavement. However, operationalizations of continuing bonds and grief intensity appear to overlap conceptually. Thus, it is still unclear what character the connection between continuing bonds and grief bears and how strong the relationship is. Three stud...
