Early quality control of stabilised dredged material by correlating heat production with strength

This study explores the use of isothermal calorimetry to assess heat release during the initial phases of dredged sediment stabilization with the primary goal of predicting the 28 days unconfined compressive strength (UCS) and enhancing the stabilization process' quality control (QC). The study was performed on dredged sediment (DS) samples collected from Göta river, Gothenburg, Sweden. The water

C4b-Binding Protein and Factor H Attenuate NLRP3 Inflammasome-Mediated Signalling Response during Group A Streptococci Infection in Human Cells

Introduction: Streptococcus pyogenes (group A streptococcus; GAS) is a pathogen causing over half a million deaths annually worldwide. Human immune cells respond to GAS infection by activating the NLRP3 inflammasome leading to the release of pro-inflammatory cytokines that control infection. We investigated the role of C4b-binding protein (C4BP) and factor H (FH) in the inflammasome response to GA

Different authorities and fire and rescue service departments in Sweden create large emissions when training their personnel in facilities for smoke producing

Akustisk pack-bed. Infångning av partiklar i nanoskalan

Pack-bed framtidens medicintekniska diagnostik? Kroppens celler kommunicerar genom att skicka information till varandra via små partiklar. Genom att fånga in dessa kan man ta del av denna information och olika sjukdomar kan därigenom detekteras. I detta arbete undersöks Pack-bed, en ny teknik där akustik används för sådan infångning.In this master thesis a novel way of trapping nanosized particles were tested. The technology used was based on acoustic trapping with seed particles. In difference to earlier devices the seed particles were held in place by a physical barrier that worked like a filter, stopping the bigger seed particles while allowing the nanosized particles to flow through, a setup that allowed for significantly

Investigation of bioinformatic pipelines for variant calling using RNA-seq data

Bioinformatiska verktyg för att hitta lungcancermutationer i RNA Lungcancer är idag den dödligaste typen av cancer, där 50% av patienterna diagnostiseras för sent. Om diagnosen kan ges i tid kan fler liv räddas. Kan analys av RNA vara lösningen på att diagnostisera fler patienter i tid? Inom cancer diagnostiken har främst DNA använts för att hitta mutationer i tumörvävnad. Ny forskning visar lovThis project has investigated tools that could be used for somatic (non-inherited) variant calling using RNA-sequence (RNA-seq) data from patients with non-small cell lung cancer (NSCLC). Identifying specific genetic variation causing growth of cancerous cells have been a major challenge within cancer research and diagnostics. Variant calling uses sequenced data to analyze differences in the genom

A methodology for assessing multiple hazards applied to Sweden

Despite extensive efforts through various international initiatives to reduce global warming, it has been determined that human induced climate change is here, that the present scale of disruption of the climate is unprecedented and will continue. Increasing weather volatility can be expected, which will most likely increase exposure to weather related hazards, e.g. wildfires, flooding.

In Situ Studies of Atomic Layer Deposition of Hafnium Oxide on (Ag,Cu)(In,Ga)Se2 for Thin Film Solar Cells

Ambient pressure X-ray photoelectron spectroscopy is employed to study in real time the chemical reactions occurring on (Ag,Cu)(In,Ga)Se2 (ACIGSe) surfaces during the first atomic layer deposition (ALD) cycle of HfOx under realistic synthesis conditions by using tetrakisdimethylamido-hafnium (TDMA-Hf) and H2O precursors. We find that the initial deposition due to surface reactions of HfOx ALD on A

A Human Factor Approach to HRI

In today’s competitive marketplace, robotics and HRI is an exciting new paradigm for changing how work is done in organisations. Its potential success depends on how HRI fit to humans and other technologies in an organisation.
