2. 1. Using airborne eDNA to study ecosystem dynamics

   Author : Edvin Karlsson; Per Stenberg; Mats Forsman; Tomas Brodin; Donald J Baird; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : In this era of global biodiversity crisis, the need to monitor ecological communities over space and time is more pressing than ever to effectively direct biodiversity conservation and management efforts. To understand the natural dynamics of an ecosystem, and the impact of anthropogenic activities related to environmental and climate change, long time series are needed to accurately link such processes to ecosystem change.

4. 2. Analysing strategic energy-related investments in process industries : applied studies at a pulp and board mill

   Author : Magnus Karlsson; Lars J. Nilsson; Linköpings universitet; []
   Keywords : MIND; Industrial energy systems; Investment; pulp and paper; TECHNOLOGY; TEKNIKVETENSKAP;

   Abstract : The potential to reduce energy demand in industrial applications is often substantiaL Since energy cost represents a considerable share of the value added in several categories of process industries, a great potential exists for cutting costs through investment, for instance in energy efficiency improvements. However, industrial energy systems form complex relations not only within the industrial unit, but also in the interaction with their surroundings. READ MORE

5. 3. Pharmacometric Models to Improve the Treatment and Development of Drugs against Tuberculosis

   Author : Robin J. Svensson; Ulrika S H Simonsson; Mats O Karlsson; Andreas Krause; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmacokinetics; Pharmacodynamics; Biomarkers; Rifampicin; Clofazimine; Therapeutic drug monitoring; Time-to-event; Time-to-positivity; Molecular bacterial load assay; Farmaceutisk vetenskap; Pharmaceutical Science;

   Abstract : With 10 million new infections yearly, tuberculosis has a major impact on the human well-being of the world. Most patients have infections susceptible to a first-line treatment with a treatment success rate of 80%, a number that can potentially be improved by optimising the first-line treatment. READ MORE

   Abstract : Solving linear systems of equations is a fundamental problem in engineering. Moreover, applications involving the solution to linear systems arise in the social sciences, business, and economics. Specifically, the research conducted in this dissertation explores solutions to linear systems where the system matrix depends nonlinearly on a parameter. READ MORE
