Den biologiska mångfalden fortsätter att minska trots att det såväl nationellt som internationellt finns en målsättning om att förlusten av den biologiska mångfalden ska hejdas. Idag anses en av de största miljöpolitiska utmaningarna vara att stoppa utarmningen av biologisk mångfald. Skogen utgör livsmiljö för hälften av alla landlevande arter i Sverige och ett hållbart skogsbruk är således livsavBiodiversity is in decline despite international and national goals of preventing this development. Preserving biodiversity is one of today’s greatest environmental policy challenges. Currently, half of all land living species in Sweden live in the forest, therefore a sustainable forestry industry is vital to ensure biodiversity. In fact, half of all red-listed species live in the forest. One of t

This Bachelor's degree project investigates how sofas can reach longer life span through circular design. It follows the steps of a classic design development process, from research and ideation to a final prototype. The result is Remain, a modular sofa that can be assembled, disassembled and reassembled multiple times enabling reuse, repair, refurbishment and recycling.

Popular Abstract in Swedish I gruppen huvudhalscancer ingår tumörer i övre luftvägar och svalg. Riskfaktorer för huvudhalscancer är rökning och alkoholöverkonsumtion. Under de senaste 20-30 åren har det skett en påtaglig ökning av insjuknandet, 4-5% per år, i det som kallas orofaryngeal cancer. Orofaryngeal cancer utgår från mellansvalget; mandlar, tungbas och mjuka gommen. Ökningen sammanfaller mThe treatment for head and neck squamous cell carcinoma (HNSCC) is surgery or (chemo)radiotherapy +/- surgery. Side effects related to therapy are long lasting and adversely affects quality of life. The incidence of oropharyngeal cancer is increasing and patients commonly present an advanced tumour stage with neck metastases at the time of diagnosis. The treatment protocol previously comprised rad

The problem of planning a trajectory for robots starting in an initial state and reaching a final state in a desired interval of time is tackled. We consider Model Predictive Control as an approach to the problem of point-to-point trajectory generation. We use the developed strategy to generate trajectories for transferring the state of the robot, fulfilling computational real-time requirements. E

Popular Abstract in Swedish Bekämpningsmedel och algblomningar - finns det någon koppling? Inom det konventionella jordbruket används idag regelmässigt stora mängder bekämpnings-medel, bara i sverige spreds under år 2001 mer än 1700 ton kemiska bekämpnings-medel på åkrarna. Ett stort problem med användandet av dessa ämnen är risken att de sprids och förorenar den intilliggande naturen. De kan driIn this thesis I have investigated the effects of pesticide exposure on the ecosystem level using various types of experimental ecosystems, i.e. microcosms. The direct effect of exposure to cyperemthrin, a pyretroid insecticide, was a rapid decrease of crustancean zooplankton in enclosures in a lake. In the exposed enclosures the biomass of algae, heterotrophic nanoflagellates, ciliates and bacter

The self-diffusion coefficients of water in casein solutions and gels were measured using a pulsed-gradient spin-echo nuclear magnetic resonance technique (PGSE NMR). The dependence of the self-diffusion coefficient of water on the concentration and structure-of casein is reported. The results were analyzed using a cell model. It was found that the water self-diffusion coefficient is insensitive t

ELT science drivers stress aperture, Strehl ratio, PSF definition and stability, field of view, wavelength range, flexibility, low polarisation and thermal emittance, auxiliary instruments, site and infrastructure. Applicable science categories are planets and planetary systems, stars and stellar systems, galaxies and galaxy clusters, and cosmology. ELT observations are needed for our own and othe

Consumer awareness regarding food production and food content is steadily growing. An alternative to the current model of global food chains is local production of food and local sales of food at farmers’ markets. This chapter assesses the social and economic benefits of farmers’ markets both for the farmers taking part in the markets and for the consumers purchasing the products on sale. The deve

In this article the authors reflect upon and critically examine signs of a contradiction in higher education which they discuss in terms of the tension between 'use value' and 'exchange value'. Use value here represents learning as something valuable ‘in itself’ whereas exchange value represents learning as an achievement of grades and credits to be ‘traded’ on a market. Their aim in this article

Denna rapport sammanfattar några studier som på olika sätt syftar till att förbättra metodiken för att analysera samhällsekonomiska effekter av kollektivtrafikinvesteringar. Förbättringarna som behandlas är 1) vikten av att ta med bristande kapacitet (trängsel) i kalkylerna; 2) förbättrade beräkningar av driftskostnader; 3) effekter av tillgänglighet på arbetsmarknad och produktivitet (s k ”wider

For many applications, including future giant telescopes, there is increased interest in structural cables. Usually integrated models, i.e. combined models of structures, optics and control systems are used for modeling of telescopes. Performance of structural cables is non-linear, so often a linearization is needed to include cable models in integrated models of telescopes. We present two differe

The human genome encodes 13 aquaporin isoforms with characteristic substrate specificity that are expressed at specific locations throughout the body. Of these isoforms, AQPs 1-4 serve important functions in renal water reabsorption. Consequently, specific AQP inhibitors have been proposed as 'aquaretics', a new class of drugs suitable to induce diuresis without concomitant salt wasting. Furthermo
