Extensive habitat loss and changing agricultural practices have caused widespread declines in grassland birds throughout North America. The Flint Hills of Kansas and Oklahoma--the largest remaining tallgrass prairie--is important for grassland bird conservation despite supporting a major cattle industry. In 2004 and 2005, we assessed the community, population, and demographic responses of grass...

Offset geomorphic features along the Superstition Hills fault show evidence for at least one slip event prior to the 1987 surface rupture, and possibly as many as four to five earlier prehistoric earthquakes. We documented several geomorphic features that appeared offset by multiple events by making detailed topographic maps. Offset features were abundant along reaches of the fault with high to...

Definition 1.1 A n1× n2× . . .× nk k-tensor is a set of n1 · n2 · . . . · nk numbers, which one interprets as being arranged in a k-dimensional hypercube. Given such a k-tensor, A, we can refer to a specific element via Ai1,i2,...,ik . A 2-tensor is simply a matrix, with Ai,j referring to the i, jth entry. You should think of a n1×n2×n3 3-tensor as simply a stack of n3 matrices, where each matr...

We classify all FMm1,m2,n1,n2 -natural operators A transforming projectable-projectable torsion-free classical linear connections ∇ on fibered-fibered manifolds Y of dimension (m1,m2, n1, n2) into rth order Lagrangians A(∇) on the fibered-fibered linear frame bundle L(Y ) on Y . Moreover, we classify all FMm1,m2,n1,n2 -natural operators B transforming projectable-projectable torsion-free classi...

Samples were selected at two different times. At first sampling, populations were from staff nurses who were just classified as N1, N2, N3 and N4 level according to the clinical ladder system. Samples were randomly selected from N1 and N2, N3 level subjects and N4 subjects were all selected as samples. Sample sizes were 416, and 321 questionnaires returned were usable. At second sampling, popul...

Background: Natural radionuclides in rock samples, primarily 238U (uranium), 232Th (thorium) and 40K (potassium), are the main source of radiation exposure to workers and general public and their measurement is of paramount importance from radiation protection point of view. Materials and Methods: Gamma spectrometry using HPGe detector was used to measure the radioactivity and assess the radiol...

We introduce the notion of a Common Specification of circuits that generalizes the current notion of structural similarity. A CS S of circuits N1 and N2 is a circuit of multi-valued blocks from which N1 and N2 can be produced by binary encoding. We show that the equivalence checking of N1,N2 in general resolution (which a non-deterministic proof system) is linear in the number of blocks in S. H...
