Två besök vid Blåisen, i början och i slutet av ablationssäsongen, gjorde det möjligt att studera hur landformerna bevaras och utvecklas. Det pågår mycket forskning om glaciala landformer som är en nyckel till förståelse av hur tidigThis study presents a detailed investigation into the evolution of sedimentary landforms over an ablation season at Blåisen, an outlet of the Hardangerjøkulen Icecap, Norway. The two visits to Blåisen, one each side of the ablation season, allowed the preservation and evolution of the landforms to be studied. Much research is conducted studying glacial landforms, which are key in our understanding

I takt med den ständigt pågående tekniska utvecklingen ökar även efterfrågan av digitalisering av allt fler funktioner i samhället. Många processer, transaktioner och handlingar som tidigare skedde på plats och genom möten sker idag digitalt. Bankärenden är ett av många exempel på detta, vilket tydliggjordes i Internet Stiftelsens årliga undersökning 2019, Svenskarna och Internet, då 91% av svensk

Background/Purpose: The aperture shape controller (ASC) was introduced in the Eclipse treatment planning system to reduce plan complexity by counteracting irregular multileaf collimator (MLC) shapes. This should lead to decreased difference between the planned and measured dose distribution. The ASC was investigated to examine if it could limit plan complexity so that the planned and measured dose

Vår hud är hem för en stor grupp av mikroorganismer, hudens mikroflora, som påverkar vår hälsa och vårt välbefinnande. Ändå finns det många aspekter av detta ämne som ännu är outforskade. Detta projekt syftade till att optimera en metod för analys av hudens mikroflora och effekten av hudvårdsprodukter på hudens mikroflora, från provtagning och provberedning till analys med kvantitativ polymeraskedOur skin is home to a vast community of microorganisms, the skin micro flora, which affect our health and well-being. Yet, there are many aspects of this topic that are still unexplored. This project aimed to optimize a method for analysis of the skin micro flora and the effect of skin care products on the skin micro flora, from sampling and sample preparation to analysis with quantitative polymer

Idag byggs det oerhört mycket. Nyproducerade bostäder konstrueras samt att äldre byggnader renoveras. Då är det viktigt att inte den större fokusen ligger på den ekonomiska- och ekologiska hållbarheten, utan även på den sociala hållbarheten. Detta för att förebygga ett segregerat samhälle som vi idag ser resultat av och drivs emot. Genom gemensamma bostadsgårdsytor skapar vi nya samlingsplatser. D

The claims for the potential of boreal and sub-boreal forests to combat negative effects of climate change have been substantial with over half of Earth’s primary forests found within boreal and temperate regions of the Northern Hemisphere. Given the likely occurrence of more extreme climate events in the future, ascertaining a better understanding of how climate effects, such as profound fluctu

The processes of meltwater storage in firn and the impact of refreezing on firn-coveredglaciers have been investigated on the Greenland ice-sheet. On Svalbard, climate changepromotes the disappearance of firn on glaciers. This thesis project aims to monitor theheat exchanges between the snowpack and the ice surface on a non firn-covered glacier,on Foxfonna, Spitzbergen, Svalbard, and to draw the p

The fact that solitary migratory birds can find their migration routes has indicated the possibility that a genetic basis may be involved in determining the route of migration. Researchers have also found evidence to investigate this hypothesis in various ways. The focal species of this study is the willow warbler (Phylloscopus trochilus), which has three described subspecies (trochilus, acredula

Popular Abstract in Swedish Förekomsten av hudcancer ökar i ljushyade befolkningsgrupper och hudcancer tillhör de cancergrupper som ökar mest i Sverige. De tre vanligaste formerna av hudcancer är basalcellscancer, skivepitelcancer och malignt melanom. Under 2013 utgjorde skivepitelcancer och malignt melanom ca 16 % av alla cancerfall som rapporterades in till Svenska Cancerregistret; över 6 000 faSkin cancer incidence is increasing in fair-skinned populations. The three most common skin cancers are basal cell carcinoma (BCC), squamous cell carcinoma (SCC) and malignant melanoma (MM). A correct diagnosis is crucial for an efficient and tailored treatment for the skin cancer patient. The purpose of this thesis was to evaluate different aspects of the preoperative diagnosis of skin cancer. Th

Critics maintain that there are a number of troublesome issues resulting from the construction sector’s way of operating and that these remain, despite widespread criticism and measures designed to change all of this. The construction sector’s and the critics’ manner of describing these problems fails to a large extent to take into consideration the way people function in connection with practical

The main objective of this thesis was to quantitatively estimate the gaseous exchange of carbon dioxide (CO2) and methane (CH4) between a subarctic wetland ecosystem and the atmosphere. Additionally some initial estimates of the carbon input to the atmosphere of nonmethane hydrocarbons (NMHCs) were also obtained by combining different techniques in a joint setting. The data presented were collecte

Popular Abstract in Swedish Hemofili A är en form av blödarsjuka som beror på en medfödd defekt av äggviteämnet faktor VIII (FVIII). FVIII spelar en viktig roll för att kroppens blodlevringsförmåga (s.k. koagulation) ska fungera optimalt och med nedsatt funktion hos FVIII riskerar man att drabbas av allvarliga blödningar i framför allt leder, men även i muskler, slemhinnor (t.ex. näsblödning) och

This thesis investigates the adsorption, decomposition and reactions of small molecules on flat, oxidised and vicinal surfaces of late transition metals. The main technique for these studies is high resolution core level spectroscopy (HRCLS). All the studies presented in the thesis are performed in Ultra High Vacuum (UHV). The articles can be divided into three groups. The first three articles dea

The small heat shock proteins (sHsps) are a widespread class of molecular chaperones existing in all organisms. During heat stress the sHsps protect other proteins from unfolding and aggregation. In plants the sHsps play an especially prominent part of the stress response. In this thesis chemical crosslinking and mass spectrometric mapping of crosslinked peptides has been used to investigate the

In this work conformational studies have been performed on peptides from four different systems in an attempt to gain knowledge about their biological function. Circular dichroism (CD) spectroscopy and nuclear magnetic resonance (NMR) spectroscopy in combination with distance geometry and restrained molecular dynamics simulations were the methods used. A detailed conformational study of a cyclic p

In order to better assess the role of agriculture within the global climate-vegetation system, we present a model of the managed planetary land surface, Lund-Potsdam-Jena managed Land (LPJmL), which simulates biophysical and biogeochemical processes as well as productivity and yield of the most important crops worldwide, using a concept of crop functional types (CFTs). Based on the LPJ-Dynamic Glo
