Douglas-fir (Pseudotsuga menziesii) has a wide distribution in North America and is one of the
tree species most widely distributed outside its natural range. The species has been introduced to
Europe, New Zealand, South America, and elsewhere around the world. At present, Douglas-fir
is an accepted and integral part of...

In 1861, in order to recoup foreign loans, France invaded Mexico. Assured by the Civil War in the United States that American response would be limited, Napoleon III undertook a scheme to replace the republican president Benito Juarez with a monarchy headed by the Austrian Archduke Maximilian von Hapsburg. Bracketed...

Asymmetric tensor fields present new challenges for visualization techniques such as hyperstreamline placement and glyph packing. This is because the physical behaviors of the tensors are fundamentally different inside real domains where eigenvalues are real and complex domains where eigenvalues are complex. We present a hybrid visualization approach in which...
Field and controlled environment chamber studies were carried out
to evaluate modes of action of post-harvest treatments on the development
and seed yield of cool season grasses. Red fescue (Festuca rubra
L.) was used as the primary test species.
There was no difference in total biomass production of red fescue...
Bacillus subtilis and essential oils have been explored separately for their ability to limit colonization by wood stain and mold fungi, but neither approach has been completely effective. One alternative strategy would be to combine the bacterial biocontrol with one or more natural products extracts. In this report, the ability...
Carbonic anhydrases are ubiquitous enzymes that catalyze the reverse hydration and dehydration of carbon dioxide and bicarbonate respectively. A variety of tumors in humans show overexpression of human carbonic anhydrase II (HCA II) leading to an acidic breakdown of carbon dioxide into bicarbonate. While a variety of drug inhibitors exist,...
