People who interact with rangelands on a regular basis gain practical insights about how rangelands work by living on and working with them. This local knowledge is refi ned over time as individuals see the way the land responds to weather, management, and disturbances. Local knowledge (LK) is a type of knowledge “integrally linked with the lives of people, always produced in dynamic interactio...

By constructing suitable project operators and using the coincidence degree theory due to Mawhin, the existence of solutions for (k, n−k−2) conjugate boundary-value problems at resonance with dimkerL = 2 is obtained.

Conventional wisdom holds that the circadian pacemaker of rodents and humans is minimally responsive to light of the intensity provided by dim moonlight and starlight. However, dim illumination (<0.005 lux) provided during the daily dark periods markedly alters entrainment in hamsters. Under dimly lit scotophases, compared to completely dark ones phases, the upper range of entrainment is increa...

Garrett Birkhoff’s mathematical work over the last three decades has been primarily centered on scientific computation and numerical analysis, and the other contributions to this special issue survey the broad range of his research and influence in this area. However, this subject represents only a small part of Garrett’s many and diverse interests, and the number of areas of mathematics on whi...

The benefits of moderate amounts of alcohol for a better health and longer life expectancy compared with abstinence have been suggested by the findings of numerous studies. However, controversies have emerged regarding the influence of confounding factors and the systematic errors that might have been inadvertently disregarded in the early studies. This review includes a description of the find...

Some Lie algebra analogues of Schur's theorem and its converses are presented. As a result, it is shown that for a capable Lie algebra L we always have dim L=Z(L) 2(dim(L2))2. We also give give some examples sup- porting our results.

Receptors and channels that underlie nociceptive signaling constitute potential sites of intervention for treatment of chronic pain states. The kainate receptor family of glutamate-gated ion channels represents one such candidate set of molecules. They have a prominent role in modulation of excitatory signaling between sensory and spinal cord neurons. Kainate receptors are also expressed throug...
