We study the critical energy and magnetization profiles for the Ising quantum chain with a marginal extended surface perturbation of the form A/y, y being the distance from the surface (Hilhorst-van Leeuwen model). For weak local couplings, A < Ac, the model displays a continuous surface transition with A-dependent exponents, whereas, for A > Ac, there is surface order at the bulk critical poin...

Die rol van professionele verenigings in die ontwikkeling van die verpleegberoep word bespreek. Eerstens word die drie hoofkomponente van die onderwerp, naamlik rol, ontwikkeling en professionele verenigings gedefinieer. Daarna deel die skrywer met die leser hoe sy ’n model vir verpleegstersverenigings ontwikkel het. Die uiteindelike model, die dinamiese verbruiker-inhoud-model maak voorsiening...

the use of stokes boundary values problems for the determination of the geoid requires that gravity anomalies (as boundary values) are known on geoid (as boundary). while, the gravity observations are measured on the earth&apos;s surface, to obtain boundary data, the surface gravity anomalies does are downward from the terrain onto geoid. for downward continuation (dwc) of surface gravity anoma...

Despite the saliency of raising critical thinking not only in ELT but also in other aspects of life, there is still lack of studies in this regard that need to be filled. Previous studies dealt with Faiclough’s model not that of van Dijk, and besides, they weren’t concerned about CDA effects on different proficiency levels. The present study, however, examined the impact of critical discourse a...
