DNA Analysis of PCR-Inhibitory Forensic Samples

Popular Abstract in Swedish I Sverige analyseras omkring 40 000 DNA-prover från brottsplatser varje år. DNA-profilerna jämförs mot DNA-profiler från misstänkta personer och kan på så vis användas för att knyta en person till ett brott. Alla typer av kroppsvävnader kan analyseras, såsom blod, saliv och hudceller. Vanliga bevismaterial är cigarettfimpar, flaskor, burkar och kläder. De material som cDNA evidence, linking perpetrators to crime scenes, is central to many legal proceedings. However, crime scene samples often contain extraneous substances that may interfere with the PCR-based forensic analysis, resulting in partial or negative DNA profiles. Extensive DNA purification may remove inhibitors, but involves the risk of DNA loss. In this work, pre-PCR processing was applied to improve

Physical bounds on metamaterials

Passivity is used to derive physical bounds on metamaterial devices. The bounds are determined from sum rules or optimization problems involving the stored energy. They typically relate some product between the performance and the bandwidth. The sum rules are computed from the low and/or high frequency response of the system. The corresponding stored energy is determined from a state space represe

Structural guarantees - the Union's last best hope against national arbitrariness

In line with current tendencies of ‘new governance’, this article will introduce a novel judicial tool which strikes a balance between the respect for national assessments and the effective implementation of Union law. This balance can be struck through the demands of structural guarantees; administrative safeguards, which weed out arbitrary national decision-making. The provision of transparent a

Generation of (synthetic) influent data for performing wastewater treatment modelling studies

The success of many modelling studies strongly depends on the availability of sufficiently long influent time series - the main disturbance of a typical wastewater treatment plant (WWTP) - representing the inherent natural variability at the plant inlet as accurately as possible. This is an important point since most modelling projects suffer from a lack of realistic data representing the infl

Arrenden

Heldagsseminariet tar upp de fyra olika arrendeformerna: jordbruks-, bostads-, anläggnings och lägenhetsarrende. Arrendefrågor är särskilt aktuell detta år, eftersom det har lagts en spännande utredningsbetänkande om besittningsskydd och avgiftsbestämning, och det kommer vi förstås att presentera under dagen. Vi strävar efter en allsidig behandling av ämnet och att verkligen försöka förena teori o

Why does inclusion of political representatives in advisory expert committees hamper democracy?

Abstract in UndeterminedExpert committees of different kinds giving advice to political decision makers are sometimes criticized for not being democratic. Points of criticism include the appointment of expert committee members rarely being a transparent process, expert members not being accountable to the electorate, and that the members of expert committees normally deliberating behind closed doo
