Climatic conditions during the winter in countries situated in the north can be considered severe. This is especially true for hydraulic structures, such as hydro power structures, dams, harbours, canals and some bridge foundations. Freezing of concrete in contact with unfrozen fresh water may have a considerable impact on the deterioration process of concrete. This paper presents results obtained

Firms in local industries maintain their capability to generate new export varieties by simultaneously exploiting internal and external knowledge resources. The paper introduces the notion variety triplet' to distinguish individual export varieties, where a triplet is a unique combination of a firm, a product code and a destination country. For each date, the set of variety triplets in each local

This text deals with a problem concerning processes of the productive power of knowledge. We draw on so called poststructural theories challenging the classical image of thought – as hinged upon a representational logic identifying entities in a rigid sense – when formulating a problem concerning the gap between knowledge and the object of knowledge. More specifically we are looking at this proble

We have recently shown that low plasma levels of mid-regional atrial natriuretic peptide (MR-ANP) predict development of diabetes and glucose progression over time, independently of known risk factors for diabetes development. However, since MR-ANP levels might be influenced by unknown factors causing diabetes, we cannot rule out that such relationship might be confounded. Previous studies have sh

Walkability is often researched from the perspective of certain physical features in the built environment. However, for this paper, the point of departure was to also treat walking as a transport mode for reaching destinations and performing every-day activities. A conceptual model addressing both perceptions of the built environment and perceived limits due to every-day activities was used as a

One of the major issues facing contemporary democracies is how the rapidly changing media environment influences democratic citizenship. Rather than strengthening or weakening citizenship per se, the present study analyzes whether traditional news and interactive online media encourage different forms of civic and political engagement among adolescents. More specifically, we use three waves of ann

Målet med examensarbetet är att simulera och utvärdera fordon-bro interaktion med avseende på ojämnheter i vägbana och jord-bro interaktion med olika fordonsmodeller och egenskaper på fjädringen. Parameterstudier kommer genomföras för plattram- och plattbroar. Syftet är att jämföra resultatet med den dynamiska förstoringsfaktorn enligt Trafikverket (TDOK 2013:0267) och att föreslå lämpliga rekommeThe objective of the thesis is to simulate and evaluate vehicle-bridge interaction (VBI) due to road surface irregularities and soil-structure interaction (SSI) with different vehicle models and suspension properties. Parameter studies will be carried out for integral and slab bridges. The aim is to compare the results with the current formula for the dynamic amplification factor (DAF) according t

Trovärdighetsbedömningen innebär en stor utmaning för asylsökande som åberopar skyddsskäl på grund av sexuell läggning. Syftet med den här upp-satsen är att undersöka vad migrationsdomstolen kräver för att den sökande ska anses ha gjort sin läggning sannolik. I ett första led identifieras de be-dömningskriterier som enligt rättskällorna ska ligga till grund för trovärdig-hetsbedömningen. Därefter

Voluntary employee turnover is a large cost factor for organizations. This fact justifies the research, development, and deployment of effective interventions. About four dozen predictors of voluntary employee turnover have been studied so far, but the construct of psychological safety has largely been ignored as a potential predictor of turnover in prior research of voluntary employee turnover. I

Prisutvecklingen på bostäder är något som väcker intresse på nationellt och individuellt plan. Mellan år 2008 och 2018 har kvadratmeterpriset och den genomsnittliga köpeskillingen för bostadsrätter fördubblats. Den expansiva värdeökningen är förenad med risker kopplade till hushållens skuldsättning som ökat i en snabb takt och därmed även ökat den finansiella sårbarheten. Ett alternativt sätt att
