Three groups of beetles inhabit cones of cycads (Cycadales) in the northern hemisphere and are believed to be involved in their pollination. The primitive weevil subtribe Allocorynina (Coleoptera: Belidae) is restricted to the New World cycad genera Dioon... see more

A statewide survey of Wisconsin’s Nemonychidae and Anthribidae (Coleoptera: Curculionoidea) was conducted over one full (2012) and two partial (2011, 2013) field seasons. Specimens were collected using a variety of techniques. Two species of the nemonychi... see more

The topology on primitive ideal space of Toeplitz algebras of totally ordered abelian groups can be identified through the upwards-looking topology if and only if the chain of order ideals is well-ordered. We describe the topology on primitive ideal space... see more

Dans ce papier nous présentons une nouvelle technique pour décomposer une image d’objet binaire en éléments géométriques définis (disques, ellipses, rectangles…) appelés primitives. La technique proposée fournit une description hiérarchique d’une forme bi... see more

A directed graph is primitive of exponent t if it contains walks of length t between all pairs of vertices, and t is minimal with this property. Moreover, it is exponent-critical if the deletion of any arc results in an imprimitive graph or in a primitive... see more

Specific studies of exchange, value and money in precapitalistic societies are still very few. This article’s main goal is to approach these conceptual categories through the use of a specific bibliography which, we believe, will take us to a better under... see more

In this paper we will determined all of the primitive and imprimitive Soluble Subgroups of GL(4,pk). It turns out that the number of types of the irreducible Soluble Subgroups in GL(4,pk)are 10 types and are Mi,i=1,…,10. moreover we find these subgroups.

Almost all of the major applications in the specific Fields of Communication used a well-known device called Linear Feedback Shift Register. Usually LFSR functions in a Galois Field GF(2n), meaning that all the operations are done with arithmetic modulo n... see more
