Modelling of Curved Glass Elements - Cold-Bent Glass and Simplified Models

Glasarkitektur utvecklas ständigt med ökande krav på estetik, funktionalitet, och hållbarhet. Användningen av böjda glaselement blir allt vanligare i modern byggnation. Traditionellt tillverkas krökt glas av floatglas som upphettas över glasets transitionstemperatur och formas till önskad krökning. Denna teknik är tids- och energikrävande och därmed relativt kostsam. Av denna anledning används anGlass architecture continues to evolve with increasing demands for aesthetics, functionality, and durability. The use of curved glass elements is becoming increasingly common in modern constructions. Traditionally, curved glass is made of float glass that is heated above the glass transition temperature and formed into a curved shape. This technique is time- and energy-intensive, and consequently,

Critical levels of atmospheric pollution: criteria and concepts for operational modelling of mercury in forests and lake ecosystems.

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

Complementary strategies to improve positive response and outcome in patients with advanced heart failure undergoing CRT therapy

AbstractCardiac resynchronization therapy (CRT) has improved quality of life and survival in select heart faillure patients, however 30-40% of patients do not show objective benefit from the treatment. At the same time there is little evidence about the long term effect of changes in medical treatment in these patients. Several factors have been examined to improve the response rate in the ”non-re

Ocean Wave Prediction for Arrays of Wave Energy Converters

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

Prevention of intimal hyperplasia after balloon angioplasty and / or stent insertion. or How to mend a broken heart - Just say NO.

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

Testing palaeomagnetic and 14C based geochronological methods in the Baltic Sea

Popular Abstract in Swedish Östersjön är ett grundhav med tillförsel av saltvatten från havet och sötvatten från omgivande floder. De två vattenmassorna är vertikalt skiktade, vilket resulterar i en estuarin cirkulation, vilken har genomgått stora förändringar till följd av landhöjningen efter senaste nedisningen. För att kunna rekonstruera havsmiljöers förändringar bakåt i tiden är det nödvändigtThe Baltic Sea is a continental shelf sea that is influenced by both river runoff and marine water. The two water masses are vertically stratified in the Baltic Sea, resulting in a positive, estuarine circulation system, which has undergone changes in the past due to isostatic uplift of the Baltic basin. For researchers to understand past changes in the marine environment of the Baltic Sea, a soun

Late-Glacial and Holocene forest dynamics at Steregoiu in the Gutaiului Mountains, Northwest Romania

Pollen analyses and AMS C-14 measurements were performed on lacustrine sediments and peat deposits from the former crater lake Steregoiu in a mid-altitude area in the Gutaiului Mountains in NW Romania in order to provide a detailed reconstruction of the vegetational development of the area during the Late-Glacial and Holocene. The bottom sediments are siliciclastic and were deposited probably duri

The Gastrin-ECL Cell Axis. Functional Aspects

Popular Abstract in Swedish Mag-tarmkanalen utgör kroppens största hormon-producerande organ. Många av de hormon-producerande cellernas funktion är ännu okänd och mycket lite är känt om den betydelse de kan ha vid olika sjukdomar i mag-tarmkanalen. I magsäckens syraproducerande del (fundus) finns 4 hormon-producerande celler, av vilka ECL cellen (65 %) och A-lika cellen (25 %) tillsammans utgör caThe ECL cells constitute a prominent endocrine cell population in the acid-producing part of the stomach. They are controlled by circulating gastrin released from G-cells in the antrum. In response to gastrin, they secrete histamine, that in turn stimulates the parietal cell to secrete acid. The first aim of the study was to prepare isolated ECL cells of high purity and to study and identify regul

Combinatorial Synthesis of Pilicides

This thesis describes a combinatorial approach to design and synthesis of three libraries of compounds, referred to as pilicides, designed to target periplasmic chaperones present in uropathogenic Escherichia coli bacteria that are the main cause of urinary tract infections. Periplasmic chaperones are required for assembly of adhesive organelles, i.e. pili, which recognize and bind to specific rec

NMR Studies of Bacterial Albumin-Binding Modules

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 Plasma Membrane H+-ATPase - Identification of a 14-3-3 binding motif

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

Small-scale climate variability and its ecosystem impacts in the sub-Arctic

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

A Surface Temperature Initiated Closure (STIC) for surface energy balance fluxes

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

Geographical variation and systematics of the tetraploid marsh orchid Dactylorhiza majalis subsp sphagnicola (Orchidaceae) and closely related taxa

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

Peatland dynamics in response to past and potential future climate change : A regional modelling approach

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

ONSHORE WINDMILL FOUNDATIONS - Evaluation of new proposals

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

Transcriptional Analysis of Cell-Sorted B-cell Lymphomas From High-throughput to Focused Identification of Molecular Targets

B cell lymphomas (BCLs) are a group of severe cancers, afflicting both men and women at different ages. Gene expression profiling (GEP), have during the latest decades fundamentally contributed to a better classification and biological understanding of the different BCLs. Most studies using GEP have analyzed mRNA from tumor tissue constituted of both tumor cells and non-malignant bystander cells.
