The wetting of non-porous solid surfaces by liquids is commonly quantified by contact angle measurements. However, it is well known that wettability...
In many schools, drugs, vandalism, assaults,
thefts, and violence against both students and teachers
have destroyed the orderly atmosphere needed for teaching
and learning. While juvenile criminal behavior,
both in school and elsewhere, is caused by a large and
complex set of sociological and psychological conditions,
there is evidence that...
John Keats, as a principal figure in the Romantic
movement in Europe, reacted against the philosophy of the
Enlightenment. His poetry and letters are testament to his
distrust of, and resistance to, an ever increasingly
clinical and "reasonable" society. Keats's poetic thought--imaginative,
speculative, dialectic--is the antithesis of an
Enlightenment philosophy...
Understanding the frequency, magnitude, and nature of explosive volcanic eruptions is essential for hazard planning and risk mitigation. Terrestrial stratigraphic tephra records can be patchy and incomplete due to subsequent erosion and burial processes. In contrast, the marine sedimentary record commonly preserves a more complete historical record of volcanic activity...

Current research indicates that the expansion of
western juniper can inhibit soil water retention, storage
and prolonged releases from watersheds. This phenomenon
is of great importance in eastern Oregon, as western
juniper is encroaching into sagebrush/grass communities
with a correlated reduction in herbaceous ground cover,
resulting in reduced infiltration rates...
Western juniper (Juniperus occidentalis) encroachment has been associated with increased soil loss and reduced infiltration resulting in the loss of native herbaceous plant communities and the bird and animal species that rely on them. Hydrologically, however, change in water yield has been linked with the amount of annual precipitation a...
