Popular Abstract in Swedish Atmosfäriskt nedfall är den största källan till miljögiftet PCB i sötvatten. I flertalet vattendrag, exempelvis Emån, fungererar också sediment som en källa. Ett pappersbruk i anslutning till Emån hade använt returpapper som innehöll PCB som råvara. PCB följde med utsläppen till ån och lagrades in i sedimenten. Miljögiftet läckte sedan ut långsamt till vattnet. Största Atmospheric deposition is one source of persistent pollutants such as polychlorinated biphenyls (PCB) in aquatic environments. Other point sources can also contribute to the PCB loadings in the water. In the Emån River, in southeast Sweden, contaminated sediment was a source of PCB, the largest deposits of it being found in a small lake connected with the river, Lake Järnsjön, the sediment of it c

The properties of particle-induced X-ray emission, PIXE, and secondary target mode X-ray fluorescence, XRF, applied to the analysis of unprepared drill cores in open air have been evaluated. Typical detection limits for elements heavier than Mg have been determined for a PIXE-system with an external 2.55 MeV proton beam and for an XRF-system with Ti, Mo and Tb secondary targets. These two systems

Popular Abstract in English The energy demands of human society are huge and will keep increasing for the foreseeable future. Fossil fuels have largely been able to meet those demands for the last centuries, but issues of sustainability and global warming have brought about a need for alternative energy sources. The emission of the sun supplies earth with an energy that is many thousand times largOrganic solar cells employing fullerenes blended with conjugated polymers as the main light-absorbing material have achieved power conversion efficiencies exceeding 10%. They hold promise as an alternative energy source with many advantages in terms of long-term sustainability and reduced greenhouse gas emissions. Detailed information on the electronic and geometric structure of the molecules invo

In magnetomotive ultrasound (MMUS) imaging superparamagnetic iron oxide nanoparticles (NP) are used as contrast agents and a time-varying external magnetic field acts to move the particles and thereby the nanoparticle-laden tissue. Recently we proposed a frequency and phase sensitive algorithm to reduce motion artifacts. However, the method is not quantitative as the particle movement induced is d

Both timber and glass are materials that have aesthetically pleasing properties. An appealing idea is to combine them to overcome the drawbacks and utilise the beneficial mechanical properties. Adhesive bonding with an appropriate adhesive could provide a uniform stress distribution at the transition between the materials.This report presents a study of three different adhesives, silicone, acrylat

Popular Abstract in Swedish Skador i knäleden är vanligt förekommande bland unga fysiskt aktiva personer. I västvärlden drabbas årligen ca 1 per 1000 invånare av skada i knät. I ungefär en tredjedel av dessa knäskador drabbas främre korsbandet. I samband med främre korsbandsskada, är det vanligt med skador på menisker, kollateralligament och brosk. Ruptur av främre korsbandet, med eller utan andraThe overall aims of this work were to evaluate a method of assessing postural control, measured by balance in single-limb stance on a force platform, and to study balance in single-limb stance in individuals with non-operated anterior cruciate ligament (ACL) injury in comparison with that of uninjured controls. Ninety-nine patients (99) with ACL injury and 141 uninjured subjects were included in

Popular Abstract in Swedish Hypertoni (högt blodtryck) och typ 2 diabetes (åldersdiabetes) är vanligt förekommande sjukdomar i Sverige. Ingen av sjukdomarna ger inledningsvis några särskilda symptom. Det är dock viktigt att upptäcka och behandla dessa tillstånd, eftersom de ger upphov till ökad sjukdom och till överdödlighet i hjärt-kärlsjukdomar såsom hjärtinfarkt, hjärtsvikt och slaganfall. FöreTo examine cardiovascular disease risk factors, control of hypertension and survival in patients with hypertension treated in primary care, patients with hypertension and/or type 2 diabetes were surveyed for cardiovascular disease risk factors and treatment 1992-1993. For reference, a random population sample from the same community was surveyed 1993-1994. During 1998, antihypertensive prescriptio

This thesis consists of four papers A, B, C and D. Paper A and B treats the simulation of stochastic differential equations (SDEs). The research presented therein was triggered by the fact that there were not any efficient implementations of the higher order methods for simulating SDEs. So in practice the higher order methods required at least the same amount of work as the Euler method to obtain

Lärarhögskolan i Malmö var en del av Lunds universitet fram till 1998, då den inordnades i nystartade Malmö högskola. I samarbete med Högskolan Kristianstad blev Lunds universitet 2011 återigen ansvarigt för en lärarutbildning, en ämneslärarutbildning som startade med examenstillstånd i ämnena engelska, historia, samhällskunskap och svenska. Föreliggande antologi syftar till att spegla utbildnings

Execution trace graph analysis of dataflow programs has been demonstrated to be an effective way for exploring and optimizing the design space of many core applications. In this work a novel transformation from the execution trace graph to an event driven linear system is proposed. It is also illustrated how the trace space of can be effectively reduced and well known system control techniques can
