Abstract European policy recommends that biomass production occur on marginal land, such as poorly draining Stagnosols. Compared to annual cropping, perennial crops may better mitigate N 2 O emissions at sites, through more complete denitrification. To test hypothesis, we compared and fluxes from the soils of a crop (cup plant, Silphium perfoliatum L.) an (silage maize, Zea mays L.). Intact soi...

there are mainly two methods of deep drawing analysis; experimental and analytical/numerical. experimental analysis can be useful in analyzing the process to determine the process parameters that produce a defect free product, and the analytical/numerical modeling can be used to model and analyze the process through all stages of deformation. this approach is less time consuming and more econom...

Everybody’s favorite theorem on Lusternik-Schnirelmann category is Eilenberg’s cup product theorem: if there is a nonzeroN-fold cup product in h̃∗(X), then cat(X) > N . Unfortunately, this theorem often fails to detect the full category of a space X; this is the case, for example, when X is a lens space Lp (with p odd) or X = Sp(n). In [4], Fadell and Husseini introduced the concept of the categ...

BACKGROUND Contact pressure of UHMWPE acetabular cup has been shown to correlate with wear in total hip replacement (THR). The aim of the present study was to test the hypotheses that the cup geometry, abduction angle, thickness and clearance can modify the stresses in cemented polyethylene cups. METHODS Acetabular cups with different geometries (Link: IP and Lubinus eccentric) were tested cy...

Minkowski’s second theorem can be stated as an inequality for n-dimensional flat Finsler tori relating the volume and minimal product of lengths closed geodesics which form a homology basis. In this paper we show how fundamental result promoted to principle holding larger class manifolds. This includes manifolds first Betti number dimension do no necessarily coincide, prime example being case s...

OBJECTIVES To explore differences in experiences of care reported in the Cancer Patient Experience Survey (CPES) between patients with cancer of unknown primary (CUP) and those with metastatic disease of known primary (non-CUP); to determine insights pertaining to the experiences of care for CUP respondents from free-text comments. DESIGN Two separate, but related, studies, involving secondar...

We show that the existence of a nontrivial Massey product in the cohomology ring H∗(X) imposes global constraints upon the Riemannian geometry of a manifold X . Namely, we exhibit a suitable systolic inequality, associated to such a product. This generalizes an inequality proved in collaboration with Y. Rudyak, in the case when X has unit Betti numbers. The inequality is a volume lower bound, a...

We show that the small quantum product of the generalized flag manifold G/B is a product operation on H * (G/B) ⊗ R[q 1 ,. .. , q l ] uniquely determined by the fact that it is a deformation of the cup product on H * (G/B), it is commutative, associative, graded with respect to deg(q i) = 4, it satisfies a certain relation (of degree two), and the corresponding Dubrovin connection is flat. We d...
