"In this paper, we study the global existence in time of solutions for a parabolic reaction di usion model with full matrix coe cients on bounded domain. The technique used is based compact semigroup methods and some estimates. Our objective to show, under appropriate hypotheses, that proposed has solution large choice nonlinearities."

We consider the di?erential equation f<sup>''</sup> +A(z)f<sup>'</sup> +B(z)f = 0, where A(z) and B(z) are entire complex functions. improve various restrictions on coe?cients prove that all non-trivial solutions of in?nite order.

Adverse weather is the leading cause of fatalities in general aviation (GA). In prior research, influences of ground visibility, cloud ceiling height, financial incentive, and personality were tested on 60 GA pilots' willingness to take off into simulated adverse weather. Results suggested that pilots did not see " weather " as a monolithic cognitive construct but, rather, as an interaction bet...

Genomewide selection (GWS) is markerassisted selection without identifying markers with signifi cant effects. Our previous work with the intermated B73 × Mo17 maize (Zea mays L.) population revealed signifi cant variation for grain yield and stover-quality traits important for cellulosic ethanol production. Our objectives were to determine (i) if realized gains from selection are larger with GW...

The objective of this study was to develop an accurate and simple method for measuring the engineering coeffi cients of the 3D elasticity tensor of wood. A method using a semi-ring extensometer (SRE) and a compression specimen (6-specimen technique) is proposed. The SRE is made of a semi-ring stainless steel blade pin-jointed to two aluminum fi xing plates, and two resistance strain gauges bond...

Bernstein coe cients provide a discrete approximation of the behavior of a polynomial inside an interval. This can be used for example to isolate real roots of polynomials. We prove a criterion for the existence of a single root in an interval and the correctness of the de Casteljau algorithm to compute e ciently Bernstein coe cients. Key-words: Polynomials, de Casteljau, Bernstein polynomials,...

ABSTRACT: Video image analysis (VIA) images from grain-fi nished beef carcasses [n = 211; of which 63 did not receive zilpaterol hydrochloride (ZIL) and 148 received ZIL before harvest] were analyzed for indicators of muscle and fat to illustrate the ability to improve methodology to predict saleable meat yield of cattle fed and not fed ZIL. Carcasses were processed in large commercial beef pro...

Conventional trade theory, which combines the Heckscher-Ohlin theory and the Stolper-Samuelson theorem, implies that expanded trade between developed and developing countries will increase wage equality in the former. Th is theory is widely applied. It serves as the basis for estimating the impact of trade on wages using two-sector simulation models and the net factor content of trade. It leads...

L It is a result familiar in the theory of automorphic form s that an entire automorphic form of positive dimension on an H-group is identically zero (see sec. 2 for the definitions). This follows immediately , for exa mple, from the well-known exac t formula for the Fourier coefficie nts of automorphic forms of positive dimension ([1], p. 314).1 Another proof is by means of a formula for the n...
