Syftet med denna studie har varit att söka ett systematiskt sätt att hantera problemsituationer under examensarbetshandledning. Ett teoretiskt ramverk har framställts med hjälp av litteratur om arbetspsykologi respektive handledning av doktorander. För att testa relevans och giltighet av ramverket genomfördes en intervju-undersökning om hantering av problematiska handlednings-situationer bland lär

We have tested the hypothesis that environmental factors can influence postischemic progenitor cell survival and differentiation in the dentate gyrus. The proliferation marker bromodeoxyuridine (BrdU) was administered during 7 days starting 24 h after ligation of the right middle cerebral artery. Postoperatively the rats were housed in standard cages or transferred to enriched environment 24 h or

Popular Abstract in Swedish De flesta kommer i kontakt med medicinskt ultraljud under sina liv, t.ex vid foster- eller hjärtdiagnostik. Det vanliga intrycket av ultraljud är en grynig bild eller film som kan framstå som svårtolkad för en lekman. Sanningen är att ultraljud även kan vara svårtolkat för experter, vilket gör att kliniskt arbete med ultraljud är tidskrävande. Detta är en anledning tillThe interpretation of ultrasonic imagery is typically not straightforward and of quite subjective nature and therefore strongly dependent on the expertise of its users. Thus the development of algorithms which aid in the interpretation of ultrasonic data is a highly relevant topic. This thesis examines aspects of segmentation and registration of ultrasonic data, utilizing the fact that the ultraso

Popular Abstract in Swedish Cellulosabaserade vattenlösliga polymerers egenskaper i lösning och vid ytor har undersökts. Tyngdpunkten har legat på interaktioner med tensider och på effekter av polymerenas utpräglade multikomponentnatur.The solution and interfacial properties of an associative water-soluble cellulose derivative, ethyl(hydroxyethyl)cellulose (EHEC) have been investigated. Main themes have been to study the effect of hydrophobic modification of the polymer (HM-EHEC) and the interactions with surfactants, both in bulk and at interfaces. The association strength of the HM-EHEC network was found to be modulated by eit

This dissertation is a contribution to the knowledge of the computational complexity of discrete combinatorial problems. 1. The first problem that we consider is to compute the maximum independent set of a box graph, that is, given a set of orthogonal boxes in the plane compute the largest subset such that no boxes in the subset overlap. We provide an $mathtt{exp}(O(sqrt nlog n))$-time algorithm

BACKGROUND: Folate is involved in DNA synthesis and methylation and may thereby influence carcinogenesis. OBJECTIVES: We examined plasma folate (P-folate) concentration in relation to genotypes of the folate-metabolizing enzyme methylenetetrahydrofolate reductase [MTHFR 677C
