Respiratory disease conditions continue to cause heavy economic losses in the poultry industry. They are usually caused by viral, bacterial, mycotic or parasitic agents and the course of the diseases can be influenced by environmental conditions and management failure (JOUBERT et al., 1999). At the beginning of 90`s bacteriological examinations from turkeys and chickens suffering from respirato...

The several refugee crises, the continuous degradation of the environment, and the nativism of some influential religious and political sectors are bringing about a new era of activism in some sectors of society. Given the deep-time perspective, the international nature of palaeontology, the exposure through field work and museum visits to intercultural exchanges in different geographic setting...

In this paper, the global robust asymptotic stability of the equilibrium point for a more general class of bidirectional associative memory (BAM) neural networks with variable time of impulses is addressed. Unlike most existing studies, the case of non-fix time impulses is focused on in the present study. By means of B-equivalence method, which was introduced in Akhmet (2003, 2005, 2009, 2010),...

This paper looks at the theoretic roots of current connectivity compression schemes to establish a visual framework within which the differences and similarities of various scheme become intuitive. We show the intimate connections between the classic work on planar graph coding by Turan and recent schemes, such as Edgebreaker, Face Fixer, and the optimal coding by method of Poulalhon and Schaef...

Let fin be the expected order of a random permutation, that is, the arithmetic mean of the orders of the elements in the symmetric group Sn. We prove that log/in ~ c\/(n/\ogn) as n -> oo, where c = 2 / ( 2 I °° log log I — — I dt\ 1. Overview If a is a permutation on n letters, let Nn{a) be the order of a as a group element. For a typical permutation, Nn is about n . To make this precise, we qu...
