Popular Abstract in Swedish Polycykliska aromatiska kolväten (PAH) är en grupp organiska ämnen som kan vara giftiga men även starkt cancerframkallande. De bildas vid förbränning av organiskt material vid låg syretillförsel och återfinns i olika produkter som tjära och fossila bränslen. De källor som tillför störst mängd till miljön idag är bostadsuppvärmning med ved, kol och olja (i Sverige ca 2/3Polycyclic aromatic hydrocarbons (PAHs) are a group of organic pollutants of great environmental concern, due to their toxicity, carcinogenicity and long persistence in the environment. To determine the potential risk associated with PAHs released from contaminated soil or waste materials, knowledge is required on the leachable concentrations of PAHs and the amounts available for release. The obj

The changing customers’ behavior nowadays strongly affects the market situation in any type of industries. Markets are demanding a shorter delivery lead time, shorter product life cycle and higher flexibility to fulfill customers’ expectation. In order to fully adapt in this kind of situation and maintain competitiveness in the market, a company need to have better collaboration internally and ext

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

Från och med 2022 ställer Boverket krav på att klimatpåverkan från nyproducerade byggnader ska redovisas uttryckt i kg koldioxidekvivalenter per kvadratmeter bruttoarea. Den s.k klimatdeklarationen utgår från livscyklisk metodik där produktskedet och byggproduktionsskedet omfattas. I klimatdeklarationen ska även periodiskt underhåll och livslängder för klimatskalet noteras. Många branschaktörer arAs of 2022, the Swedish National Board of Housing, Building and Planning (Boverket) is requiring that the climate impact from newly developed buildings has to be calculated and reported in terms of kg carbon dioxide equivalents per m² of gross area. The so-called climate declaration is based on life-cycle methodology and covers the product stage and the construction process stage. Periodic mainten

The use of Penman-Monteith (PM) equation in thermal remote sensing based surface energy balance modeling is not prevalent due to the unavailability of any direct method to integrate thermal data into the PM equation and due to the lack of physical models expressing the surface (or stomatal) and boundary layer conductances (g(S) and g(B)) as a function of surface temperature. Here we demonstrate a

Mercury (Hg) is regarded as a major environmental concern in many regions, traditionally because of high concentrations in freshwater fish, and now also because of potential toxic effects on soil microflora. The predominant source of Hg in most watersheds is atmospheric deposition, which has increased 2- to >20-fold over the past centuries. A promising approach for supporting current European effo

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

Intracerebral neural transplantation offers a new strategy to combat Parkinson’s and Huntington’s diseases. However, a host immune response against a histoincompatible neural graft in the brain may jeopardize transplant survival. We transplanted dissociated mesencephalic tissue prepared from Sprague-Dawley (SD) (syngeneic), Lewis (allogeneic) rats or mice (xenogeneic), into 6-hydroxydopamine (6-OH

Protein S deficiency is an autosomal dominant trait affecting around 10% of families thrombophilic families. The high affinity interaction of approximately 60% of protein S with C4b -binding protein (C4BP) has raised a complicated situation for the diagnosis of deficiency states. Because only free protein S functions as cofactor in the protein C anticoagulant, it is important to measure free prote

Since publication of the 1998 UNEP Assessment, there has been continued rapid expansion of the literature on UV-B radiation. Many measurements have demonstrated the inverse relationship between column ozone amount and UV radiation, and in a few cases long-term increases due to ozone decreases have been identified. The quantity, quality and availability of ground-based UV measurements relevant to a

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 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

The human-environment connection in the mostly rural drylands of sub-Saharan Africa forms a complex, interlinked system that provides ecosystem services. This system is susceptible to climatic variability that impacts the supply of its products, and high population growth, which impacts the demand for these products. When plants remove carbon dioxide from the atmosphere through the process of phot

En majoritet av de nordliga torvmarkerna utvecklades under holocen som ett resultat av en positiv massbalans mellan nettoprimärproduktion och heterotrofa nedbrytningshastigheter. Sedan dess har de lagrat stora mängder kol i terrestra ekosystem. En betydande del av dessa områden sammanfaller också med regioner med underliggande permafrost och uppvisar olika ackumulationsmönster av torv. Således, föThe majority of the northern peatlands developed during the Holocene as a result of a positive mass balance between net primary productivity (NPP) and heterotrophic decomposition rates. Over that time they have sequestered a huge amount of carbon in terrestrial ecosystems. A significant proportion of these areas also coincides with areas underlain with permafrost and shows a diverse range of peat

This dissertation examines the public interventions, rhetoric, and actions of liberal intellectuals in Turkey between the early 1990sand 2012 regarding the rights of Kurdish and Islamic actors and restrictions on discussing the Armenian Genocide of 1915. Theanalysis of diverse texts published by the interconnected intellectuals – newspaper columns, academic articles, policy papers,reports, and man

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
