Snowpack dynamics have a major influence on wildlife movement ecology and predator–prey interactions. Specific snow properties such as density, hardness, depth determine how much an animal sinks into the snowpack, which in turn drives both energetic cost of locomotion predation risk. Here, we quantified relationships between five field-measured variables track sink depths for widely distributed...

Background and Aim: The purpose of this study was to evaluate residual dentin thickness of the root and the area of the canal lumen in the coronal region of the mesiobuccal and mesiolingual canals of the lower first molars after canal preparation with the common method of using hand files and Gates Glidden drills or ProTaper rotary files, by Spiral Ct-Scan. Materials and Methods: In this exp...

In poor visibility, paired approaches to airports with closely spaced parallel runways are not permitted, thus halving the arrival rate. With Global Positioning System technology, datalinks and cockpit displays, this could be averted. One important problem is ensuring safety during a blundered approach by one aircraft. This is on-going research. A danger zone around the blunderer is required. I...

A primary challenge from the relativist to the contextualist about epistemic modals is to explain eavesdropping data—i.e., why the eavesdropper is inclined to judge the speaker as having uttered an epistemic modal falsehood (when she is so inclined), even though the speaker’s utterance is true according to reasonable contextualist truth conditions. The issue turns in large part on the strength ...

BACKGROUND Obstetric danger signs are not the literal obstetric complications, merely symptoms that are well named by non-clinical personnel. The identification of these danger signs and its relation with complications during pregnancy would increase the capacity of women, their partners and families to seek for timely health care, following the appropriate steps to insure a safe birth and post...

Temperate alpine glacier survival is dependent on the consistent presence of an accumulation zone. Frequent low accumulation area ratio values, below 30%, indicate the lack of a consistent accumulation zone, which leads to substantial thinning of the glacier in the accumulation zone. This thinning is often evident from substantial marginal recession, emergence of new rock outcrops and surface e...

BACKGROUND Raising awareness of women on danger signs of pregnancy, childbirth and the postpartum period is crucial for safe motherhood. In Ethiopia, a country where maternal morbidity and mortality is high little is known about knowledge level of pregnant women on obstetric danger signs. The objective of this study was to assess pregnant women's knowledge about obstetric danger signs in Aleta ...
