We report on the performance of a grazing incidence spherical grating monochromator installed at MAX I and designed to cover the photon energy range from about 15-200 eV with high resolving power. It is intended mainly for angle-resolved photoemission work. Therefore, both refocusing optics, to obtain a small spot size at the sample, and a higher order light suppressor, to reduce the content of hi

Bacterial surface-associated plasmin formation is believed to contribute to invasion, although the underlying molecular mechanisms are poorly understood. To define the components necessary for plasmin generation on group A streptococci we used strain AP53 which exposes an M-like protein ("PAM") that contains a plasminogen-binding sequence with two 13-amino acid residues long tandem repeats (a1 and

During the establishmen of an NGO Maritime Rescue Service (MRS)in the Lake Albert region in Uganda, the intelligence information management (IM) needs of the operation cere compared with earlier IM experiences of a combined peace keeping mission. This paper describes the MRS oparation IM needs. Furthermore, the Joint Command and Control Information Exchange Data Model (JC3IEDM) is introducea as th

Denna uppsats markerar ett nytt och kompletterande spår i Certecs verksamhet: att i datormodellens form simulera mänskligt lärande. Förhoppningen är att det därigenom skall komma fram nya idéer både om lärande och om pedagogiska möjligheter kring hur man kan stötta lärandet. Certec kommer att medverka till att den nya kunskapen i första hand skall komma människor med inlärningssvårigheter till god

This study explored individual differences in eye movements during visual imagery. Eye movements were recorded for participants who recalled a picture from memory while looking at a blank screen. All participants were tested for working memory capacity and the OSIVQ (Blazhenkova & Kozhevnikov, 2009) was used as an assessment for individual differences in object imagery, spatial imagery and ver

Before radioactive ion beams became available, the Gamow-Teller (GT) giant resonance was studied using charge-exchange reactions such as (p,n) and (He,t). In beta-stable nuclei, which can be used as targets, the GT giant resonance lies above the ground state of the mother nucleus. In this thesis the GT strength distribution is studied for deformed proton drip line nuclei with 28 < Z < 72. For thes

Coevolutionary interactions are thought to have spurred the evolution of key innovations and driven the diversification of much of life on Earth. However, the genetic and evolutionary basis of the innovations that facilitate such interactions remains poorly understood. We examined the coevolutionary interactions between plants (Brassicales) and butterflies (Pieridae), and uncovered evidence for an

Conceptual design is the first phase in the design process in which all the requirements and design objectives are synthesized into conceptual alternatives. In practice today, major decisions regarding the buildings geometry, massing, and overall form are usually made during the first phase. Considering structural performance requirements during conceptual design enhances interdisciplinary interac
