I had the opportunity to work with the flood plain community: Nossa Senhora das Gracas in the Amazon in Brazil. During a month long stay I observed the daily life of the people. A life where the inhabitants shape their daily routines after the rising and dropping Solemoes river. Solemoes is a part of the Amazon river. I identified a need of harvesting water during the low water season, when the r

I takt med att världens befolkning ökar och allt fler väljer att bosätta sig inne i staden ökar behovet av att hitta smarta och hållbara sätt att förtäta. En stad har sina begränsningar och därför har det genomgående i projektet varit viktigt att undersöka hur vi kan töja på stadens gränser och tillföra nya värden utan att tumma på befintliga kvaliteter. Att förtäta en stad är en möjlighet att höjAs the world population increases and more people choose to settle in the city the need to find smart and sustainable solutions to densify increases. A city has limitations and therefore it has been important to look at how we can stretch the city´s borders and adding new values without compromising the existing qualities. To densify a city is an opportunity to improve existing urban spaces and in

Utsläpp från jordbruk och förbränning av fossila bränslen ökar den atmosfäriska belastningen av reaktivt kväve (N). Kvävenedfall beräknas fortsätta utgöra betydande skada både för miljön och människors hälsa under de kommande decennierna. Övergödning som resultat av kväveläckage är en av de negativa effekterna av nedfallet. Den inträffar när tillförseln av N in i ett ekosystem överstiger upptagninEmissions from agriculture and the combustion of fossil fuels increase the atmospheric load of reactive nitrogen (N). N deposition is projected to continue posing significant harm both for environmental and human health over the upcoming decades. Eutrophication as a result of N leaching is one of the negative effects of heavy deposition. It occurs when the input of N into an ecosystem exceeds its

Throughout history, human civilisation and wildlife have instinctively settled close to water and coastlines out of necessity for resources. It has always been a natural instinct, yet we have also continually adapted to weather conditions and relocated when resources were found elsewhere. We have always been flexible and mobile, adapting to nature and allowing it to lead and guide us. With the ris

DERA, 2-deoxyribose-5-phosphate aldolase, catalyzes the retro-aldol cleavage of 2-deoxy-ribose-5-phosphate (dR5P) into glyceraldehyde-3-phosphate (G3P) and acetaldehyde in a branch of the pentose phosphate pathway. In addition to the physiological reaction, DERA also catalyzes the reverse addition reaction and, hence, is an interesting candidate for bio-catalysis of carbo-ligation reactions, which

In time-selected migration birds adapt their fuel deposition and flight behaviour to maximise sustained migration speed. What are the expectations for the final part of spring migration when the transition to breeding takes place and the criterion of a maximum total migration speed is no longer relevant? Two possible strategies representing different ends of the capital – income spectrum are evalu

This paper proposes a new dynamic mode of generating bioanalytical arrays based on ultrasonic trapping of microbeads in microfluidic systems. As compared to disposable glass slide microarrays, the proposed technology utilises exchangeable microbeads as the solid phase on which bioassays are performed. The use of microbeads in biochemical analysis is advantageous due to the increased surface area a

The c-kit-encoded tyrosine kinase receptor for stem cell factor (Kit/SCFR) is crucial for the development of hematopoietic cells, melanoblasts, and germ cells. Ligand stimulation of Kit/SCFR leads to receptor dimerization and autophosphorylation on tyrosine residues. We recently showed, that protein kinase C (PKC) acts in an SCF-stimulated negative feedback loop, which controls Kit/SCFR tyrosine k

Management decisions in conservation of threatened species require trading off social needs against biodiversity values, including the prioritization of conservation locations, i.e. where conservation efforts should take place. To improve conservation decisions for the thick-shelled river mussel, Unio crassus, a highly threatened temporary parasite on fish, we performed a field study on how mussel

Leaching of dissolved organic carbon (DOC) from the forest floor and transport in soil solution into the mineral soil are important for carbon cycling in boreal forest ecosystems. We examined DOC concentrations in bulk deposition, throughfall and in soil solutions collected under the O and B horizons in three Norway spruce stands along a climatic gradient in Sweden. Mean annual temperature for the

We have analyzed the content of N-unsubstituted glucosamine in heparan sulfate from glypican-1 synthesized by endothelial cells during inhibition of (a) intracellular progression by brefeldin A, (b) heparan sulfate degradation by suramin, and/or (c) endogenous nitrite formation. Glypican-1 from brefeldin A-treated cells carried heparan sulfate chains that were extensively degraded by nitrous acid

Tawny owls Strix aluco generally roost in cryptic locations during the day. To test the hypothesis that this cryptic behaviour is an effort to avoid mobbers or avian predators, we measured diurnal behaviour and cause-specific mortality of radio-tagged birds. Non-breeding adults (assumed to be well fed individuals, optimising their own survival) roosted in less exposed locations than adults with yo

PURPOSE: Epinephrine is used in local anesthetics to induce vasoconstriction and thus reduce bleeding and prolong the anesthetic effect. Finding the optimal delay between the administration of the anesthetic and skin incision to ensure vasoconstriction and minimize bleeding is important and has recently become the subject of debate. This is the first study to assess blood perfusion and oxygen satu

This thesis deals with the general problem of controlling rigid-body systems through space, with a special focus on unmanned aerial vehicles (UAVs). Several promising UAV control algorithms have been developed over the past decades, enabling truly astounding feats of agility when combined with modern sensing technologies. However, these control algorithms typically come without global stability gu
