Popular Abstract in Swedish Ökat antal patienter som lider av kärlsjukdomar behandlas idag med interventionella metoder istället för kirurgi. Dessa metoder populärt kallade ballong sprängningar, kombineras numera oftast med inläggande av ett metallnät (stent) som hjälper till med att förstärka kärlväggen, så den inte skall falla ihop efter ballong vidgningen. Oavsett vilken metod som används, kompBackground: Restenosis is the most frequently occurring adverse event after percutaneous intravascular treatment of atherosclerotic lesions, which limits long-term patency of the intervention. Objective: The aim of the study was to evaluate if minimizing vascular injury during treatment by insertion of self-expanding stents or modifying the reparative mechanisms by local drug delivery can reduce r

Popular Abstract in Swedish Vid många industriella processer bildas olika typer av biprodukter, som kan vara mer eller mindre giftiga. En ovarsam hantering av de giftiga ämnena, eller en olycka, kan lätt leda till att den omgivande miljön blir förorenad. Förr, när man var mindre medveten om riskerna med de här ämnena hamnade de ofta i marken kring anläggningarna. Det har resulterat i många förorenBioremediation of soils is considered a low-cost alternative to other remediation techniques. Its ability to remove a number of different pollutants has been demonstrated, relying mainly on the activities of indigenous soil bacteria. The polycyclic aromatic hydrocarbons (PAHs) are considered major environmental pollutants in soil, some of them being toxic and others carcinogenic. Since high-molecu

Abstract in Undetermined To improve our knowledge of climate change and its impacts on ecosystem services, and to inform local people and governments that need assistance with the development of mitigation and adaptation strategies, climate impacts need to be understood urgently at the smaller scale. On one hand, the microclimate/topoclimate is known to be strongly decoupled from the general macro

Popular Abstract in Swedish Proteiner är uppbyggda av aminosyror som är hopkopplade med varandra och bildar långa kedjor som kan bestå av hundra- eller tusentals aminosyror. Det finns en mängd olika proteiner och de har många olika funktioner. I studierna som beskrivs här, har proteiner som finns på ytan av vissa bakterier studerats. De långa proteinkedjorna i dessa bakteriella ytproteiner är oftPeptostreptococcus magnus and group C/G streptococci are Gram-positive cocci that are part of the normal flora and reside in more or less the same locations in the host. Protein G of group C/G streptococci was originally described as binding IgGFc of several species and later shown to also bind human serum albumin and albumins from various animal species. From albumin-binding strains of P. magnus

The P-type plasma membrane H⁺-ATPases form a group of proteins only found in plants and fungi. The pumping of protons across the plasma membrane, energized by ATP hydrolysis, creates an electrochemical gradient that is essential for solute transport and internal pH regulation. The H⁺-ATPase genes are present as multigene families in the genomes of higher plants and all cell t

Dactylorhiza majalis subsp. sphagnicola is an allotetraploid marsh orchid derived from parents closely similar to present-day D. incarnata and the western European form of D. maculata subsp. maculata, suggesting that it has a postglacial origin. It extends from northwestern continental Europe into areas formerly covered by the Weichselian ice sheet in mid-Scandinavia. Here, we studied the variatio

Popular Abstract in Swedish Bakgrund: Patientflödet genom en akutmottagning regleras framförallt av tre typer av faktorer. Dessa rör i tur och ordning inflödet-, genomflödet- och utflödet av patienter. Faktorer som reglerar inflödet rör efterfrågan på sjukvård (t.ex. samhällsdemografi och tillgång på primärvård), medan faktorer som reglerar genomflödet till största delen rör akutmottagningens inteBackground: Emergency Department (ED) overcrowding occurs when the need for ED services outstrips available resources. Causes have been divided into input, throughput, and output factors, of which the last appear to be the most influential. Unavailability of inpatient beds (so-called “access block,” or “hospital crowding”) impairs ED output and is associated with increased waiting times in the ED

Changing Landscapes and Persistent Places is a study of the cultural landscape on the Bjäre peninsula in northwest Skåne. The many Bronze Age remains that give the landscape its distinctive character are the starting point for an attempt to increase our understanding of the historical depth of today’s landscape. The two perspectives of “landscape” and “places” carry the discussion forward, almost

This thesis is based on five studies. It includes the characterization of lipid micro emboli in shed mediastinal blood during cardiac surgery. The reuse of blood directly by cardiotomy suction is a common practice in order to reduce the need of blood transfusions. In shed mediastinal blood we showed that there is an abundance of lipid particles in the size range of 10-60μm. These lipid particles a

Klimatet har varit relativt stabilt under den nuvarande interglaciala epoken (Holocen) som inleddes för ungefär 11 700 år sedan. Genom klimatrekonstruktioner från olika geologiska arkiv såsom iskärnor, sjösediment och torvmossar har det ändå påvisats att snabba förändringar i klimatet har inträffat under denna epok. En sådan tidsperiod inträffade för omkring 2800 år sedan och den är intressant ur Geological archives have shown periods of abrupt climate change in the relatively stable Holocene epoch (last ca. 11 700 years). One of these periods was around 2800 cal BP. Several records, mainly from Europe, reveal a shift towards wetter, cooler and windier conditions. There are, however, indications for a global extent of the climate change. The climate change coincides with a distinct increas

En slitsmur är en geokonstruktion som utförs genom att paneler platsgjuts med marken som form. Panelerna bildar tillsammans en samverkande vägg. Tekniken är vanlig utomlands men fortfarande relativt ovanlig i Sverige. Behovet, och därmed intresset, av slitsmurar i Sverige växer dock i takt med förtätningen av städer och infrastrukturprojekt som kräver djup schaktning och anläggning. Kraven på låg A diaphragm wall is a retaining wall which is produced as a cast in-situ concrete wall. The ground itself acts as formwork. The technique is widely used internationally but it is comparably still a rare technique in Sweden. However, the need, and therefore interest in Sweden for diaphragm walls is growing as the number of inner city infrastructure projects requiring deep excavations increases. The

As the climate on earth deteriorates, actions are carried out within Europe to limit the amount of hazardous emissions to lower the environmental consequences due to greenhouse gases. A significant proportion of the emissions can be linked to the construction sector and its use of virgin resources. An area with great development potential within the construction sector is linked to its management

Short-term wave prediction is a key enabling technology for advanced control of wave energy converters (WECs), where accurate knowledge of the incident wave field over one to a few wave periods can improve power capture, reduce structural loads, and support operational decision-making. Many existing prediction methods rely on measurements at the prediction point or dedicated up-wave sensors, which

Denna uppsats undersöker vilka möjligheter en privat organisation har att använda sig av personuppgifter utan samtycke på grund av ett så kallat ”berättigat intresse” enligt personuppgiftslagen (1998:204) samt lagen om elektronisk kommunikation (2003:389). Ett berättigat intresse föreligger när behandling av en uppgift är nödvändig för ett ändamål hos den personuppgiftsansvarige eller en tredje paThis thesis examines the possibilities of a private entity to use personal data without consent, based on a so called "legitimate interest" in accordance with the personal information act (1998:204) and the electronic communications act (2003:389). A legitimate interest is in effect when processing of a piece of personal information is necessary for the liable party or a third party with

In many places across the northern hemisphere, drinking water treatment plants (WTPs) need to avert the effects of deteriorating quality in surface water sources caused by increasing lev-els of natural organic matter (NOM). The two major factors responsible for this phenomenon, also called brownification, are the greenhouse effect and changes in soil acidification. Additional treatment steps needs

Populärvetenskaplig sammanfattning: Då man för ner en elektrisk ström i marken kommer vissa material i marken laddas upp p.g.a. att positiva och negativa joner samlar ihop sig på ytor och i trånga porkanaler. Detta kallas för polarisering och kan användas för att bestämma t.ex. vad för typ av geologiska material som finns under markytan eller vart föroreningar i marken tar vägen. Fenomenet som uppIt has been shown that surveys of Induced polarization (IP) often contain data of low quality, because it is highly sensitive against different noise sources. When measuring induced polarization, where the method uses multicore cables and continuous electrode sounding (CVES, Continuous Vertical Electrical Sounding), noise phenomena such as capacitive coupling effects have to be considered. It is p

Stratigrafiska analyser har utförts på en kustklint vid Ålabodarna i västra Skåne, vilken exponerar en skärning genom en liten dödisbassäng. Syftet med undersökningen var bl a att studera vegetationsutvecklingen i ett område som, i förhållande till övriga Skandinavien, tidigt blev isfritt. Fördelen med att arbeta med sediment i en öppen skärning i stället för i en borrkärna är att sedimentens latePopular abstract: A study of sediments from a small ancient lake basin in the cliffs at Ålabodarna, western Skåne, Sweden has revealed important information about the arrival and expansion of vegetation in the area. Western Skåne is a very important area for studies of this type, as the ice streams from the final episode of glaciation during the Late Weichselian retreated from this area early rela

Windmill structures must withstand very high horizontal loading giving an extremely large overturning moment on the foundation. These structures have very low stability loads in comparison to the overturning loads. The traditional way to solve the construction problem uses a shallow foundation with a massive concrete volume or a piled foundation to resist the extreme overturning moment. This work

G protein-coupled receptor 30 (GPR30) is a G protein-coupled receptor (GPCR) that is attracting considerable attention in breast cancer and cardiometabolic regulation. Following reports that GPR30 is required for some rapid estrogen responses, e.g. increased cAMP production and ERK1/2 activity, in estrogen receptor (ER)-negative cells, GPR30 was renamed G protein-coupled estrogen receptor 1 (GPER1

The ACE-2 HILLCLOUD experiment was carried out on the island of Tenerife in June-July 1997 to investigate the interaction of the boundary layer aerosol with a hill cap cloud forming over a ridge to the north-east of the island. The cloud was used as a natural flow through reactor to investigate the dependence of the cloud microphysics and chemistry on the characteristi
