In this paper we prove a conjecture of Bulter and Graham [2] on the existence of a certain way of marking the lines in [k] for any prime k. The conjecture states that there exists a way of marking each line of [k] one point so that every point in [k] is marked exactly a or b times as long as the parameters (a, b, n, k) satisfy the condition that there are integers s, t such that s + t = k and a...

Microstrip realization of beam forming network integrated with dual-band antenna array on silicon substrate is presented. Design and implementation of broad band topologies of hybrid and phase shifter are discussed and further integrated to realize wideband 4× 4 Butler matrix. Proposed wideband Butler matrix is used to realize single-band and dual band antenna architectures on silicon substrate...

The Butler iron meteorite has been found to have, with respect to other iron meteorites, an unusually high cobalt content (1.4 percent by weight), unusually high germanium contents in the kamacite and the taenite phases, and an unusually low cooling rate (0.5 degrees C/10(6) years). It is suggested that Butler formed in a different environment from that of the rest of the iron meteorites.

Introduction Variation of the B1 field distribution at high field causes variation of the flip angles inside the patient’s body which leads to shading in the acquired images. Numerous methods have been proposed to mitigate B1 inhomogeneity. More recently, it was shown that “B1 shimming” can be performed using multiple transmitters [1,2], but utilizing these additional transmit channels effectiv...

Neste trabalho, o conceito de abjeto, tal como pensado por Judith Butler a partir da obra Julia Kristeva, é analisado e aproximado ideia butleriana uma distinção existente entre vidas passíveis enlutamento não-enlutáveis. Propomos compreensão do abjeto na dessas autoras, além estabelecer relação noção impureza antropóloga Mary Douglas. Entendemos que, Butler, existem aproximações possíveis as d...

The so-called Butler-McGehee lemma was first stated and proposed by Freedman and Waltman [11] to study persistence in three interacting predator-prey population models. Roughly speaking, the lemma says that if a trajectory, not on the stable manifold of a given isolated hyperbolic equilibrium P, has that equilibrium in its !-limit set, then its !-limit set also contains points on the stable and...
