Recently a new approach to photoemission, EXAFS and electron scattering has been developed. The correlations between target electrons are separated from the active electron-target electron correlations, and the damping effects are coming out explicitly. The theory uses van Hove diagonal Green's functions and projection operator techniques, not the usual diagram expansions. By omitting from the sta

In time hopping impulse radio, N/sub f/ pulses of duration T/sub c/ are transmitted for each symbol. This gives rise to two types of processing gain: (i) pulse combining gain, which is a factor N/sub f/, and (ii) pulse spreading gain, which is N/sub c/ = T/sub f//T/sub c/, where T/sub f/ is the mean interval between two subsequent pulses. This paper investigates the trade-off between these two typ

Abstract in Norwegian Det er artiklens grundopfattelse at alle mennesker egentlig har samme behov, men at nogle, f.eks. udviklingshæmmede (eller som Jönsson foreslår:”særkyndige”) blot har brug for særlige redskaber for at kunne opfylde sine behov. Artiklen fokuserer navnlig på behovet for sprog og kommunikation og fremhæver her den nyere teknologis muligheder for at utvikle nye sproglige redskabe

Purpose The purpose of this paper is to develop a conceptual model that can be used in future research to empirically evaluate to which extent formal and informal intra-organizational communication mediates the links among key antecedents and internal integration. Design/methodology/approach To build up the conceptual model, literature review has been conducted. We also provide a number of hypoth

A surface with periodic corrugations of suffciently small periodicity is shown to be electromagnetically equivalent to an inhomogeneous transition region (slab). Explicit expressions for the inhomogeneous transition region are found for one-dimensional corrugations and for two-dimensional corrugations a local elliptic problem has to be solved in order to find the equivalent electromagnetic properti

This conference paper deals with the question of heteronormativity, or more precisely, how heteronormativity pertains to the reception of the Swedish film by Lukas Moodysson, Show Me Love (Fucking Åmål).

Actinobacillus actinomycetemcomitans, Prevotella intermedia and Prevotella nigrescens are associated with periodontal diseases. Adhesion of these bacteria to host tissue surfaces is a prerequisite for their establishment. The surfaces in the oral cavity are bathed by secretions which emanate from salivary glands and from gingival crevicular area. Lactoferrin is one of the antimicrobial glycoprotei
