In many downstream processes microfiltration (MF) is used as the first step to separate the micro-organisms from the product-containing broth. The transmission of proteins through these MF membranes is of great importance, especially when a protein is the desired product. Usually, the largest fraction of the proteins retained in the membrane during the separation of micro-organisms is retained in
The molecular self-diffusion in concentrated aqueous mixtures based on an oppositely charged po ymer-surfactant pair has been investigated by NMR pulsed field gradient techniques. The investigated structures were an ordered cubic Pm3n phase (ca. 50 wt % water) and a disordered micellar phase, both containing cetyltrimethylammonium (CTA(+)) micelles with mixed acetate (Ac-) and polyacrylate (PA(-))
Particles from post denitrifying Kaldnes Moving Bed(TM) Process were studied using an optical borescope, a visualisation technique that provides opportunities for both qualitative and quantitative studies of the separation mechanism in Dissolved Air Flotation (DAF). Rise rates for particle/bubble aggregates were estimated showing great variability. Two groups of aggregates were distinguished; rela
Benign paroxysmal positional vertigo (BPPV) originating from the posterior semicircular canal (pSCC) is a common vestibular disorder that is easy to diagnose and usually easy to treat. The majority of patients with BPPV have no known inner ear disease; they have "primary" or "idiopathic" BPPV. However, a minority does have objective evidence of an inner ear disease on the same side as the BPPV and
Både Sveriges rättsväsende och makthavare gjorde avsteg från gällande processrätt på 1600-talet. Den samtida lagstiftningen uppställde stränga regler för rättegången, bevisvärderingen och straffen. Trolldom hade utgjort ett brott enligt lagstiftningen sedan medeltiden. Med förändringar inom rättsväsendet utökades brottet, samtidigt som anklagelser om Blåkullafärder och djävulspakter spred sig övBoth the Swedish Judiciary and rulers made deviations from applicable procedural law in the 17th century. The contemporary legislation set up strict rules for the trial, the evaluation of evidence, and the punishment. Sorcery had constituted a criminal offense according to the law since the Middle Ages. With changes within the Judiciary, the crime was expanded, while accusations of journeys to Bl
In 2018, the European Union (EU) adopted a revised version of the Renewable Energy Directive (RED 2). The directive introduced new objectives for the EU’s renewable energy sector and aimed to support the provision of renewable energy in the EU. After its adoption, the directive would be implemented in each EU member state. This thesis analyzes Sweden’s implementation of the RED 2 and applies a the
As one of the biggest coal producers in the EU and a country with a coal-based energy system, Poland is faced with a difficult challenge of transforming the energy sector. However, coal has a very powerful position in the country, protected by incumbent actors and their interests. This thesis focuses on the Bełchatów Basin, an important lignite region, and examines coal narratives and their implic
In the time of an increasing climate crisis, governments are faced with finding feasible solutions to environmental challenges. One such solution is the shift away from fossil fuels towards renewable also known as green technologies – a green transition. Renewable technologies demand vast amounts of minerals for their production which cannot be met by land mining alone. As a response to this incre
Purpose: In this study, the purpose is to explore how disruptive communication can be used as a means to overcome stigma. Methodology: This paper has analyzed four case studies in order to get a deeper understanding of the phenomenon stigma. A literature review is conducted where the concepts ‘stigma’, ‘disruptive communication’ and ‘brand identity’ is applied. The theoretical foundations were bas
Power production has a vital role in the functioning of society and will have a major part in the future of environmental and economical sustainability. Therefore, efficiencies of power plants are always a subject to improvements in order to utilise resources as efficient as possible. A Combined Cycle, combining a gas turbine topping cycle and a steam turbine bottoming cycle, is a widely used conf
This thesis deals with the question of how Hezbollah attempted to explain its involvement in the war in Syria to its supporters. Using qualitative research methods, the thesis draws on 24 speeches made by Hezbollah Secretary-General Hassan Nasrallah between 2013 and 2018. Theoretically based in the notion that Hezbollah functions as a Social Movement Organization, and through the application of fr
This project explores how a beginner friendly music production device can lower the threshold for engaging with sound creation and rhythm making. Many existing tools rely on prior knowledge or technical skill, which discourages new users from experimenting in creative ways. This project instead focuses on quick feedback, clear interaction and a tactile experience that invites curiosity and play. T
Mamma sluta kommentera på min Instagram – du förstör min image Denna kvalitativa studie ämnar öka förståelsen för individers identitetsskapande på sociala medier. En individs identitet förhandlas fram och konstrueras i samspel med andra människor. I och med sociala mediers framväxt utvecklas ständigt nya plattformar där individer kan kommunicera med andra och uttrycka sin identitet. Tidigare forsMom stop commenting on my Instagram – you are ruining my image This qualitative study aims to increase the understanding of how individuals construct their identity through social media. An identity is constructed in interaction with other people. With the development of social media new platforms constantly emerge where individuals can communicate with others and express their identities. Previo
This master thesis contributed to a project financed by the Swedish Energy Agency and managed by the housing company Eksta AB in collaboration with the consulting Company WSP. The main aim of this master thesis was to perform a theoretical optimization on the usage of own used solar electricity by transferring the surplus PV between buildings in a demonstration area in a DC-microgrid. To achieve th
One particular approach of behavioral economics has gained attention within environmental politics during the last decade. The idea of nudging (“gently pushing”) people in situations of decision-making towards the choice that in the long run is best for them as well as for the society and/or the environment seems to attract policy makers around the world. Many governments inside and outside the EU
Most aerosol particles emitted from shipping affect the climate by counteracting the greenhouse effect. Although, this masks the warming effect of greenhouse gases, aerosol particles also have a negative health effects, and therefore emissions need to be reduced. It is possible that the negative health effect could be a concern for not only city dwellers, but for people living in rural areas as we
This study is of qualitative nature where the problem area, domestic violence, is analyzed through feminist theory, aided by a critical discourse analysis. The study aims to reveal if the discourse of an official report from the Swedish government, named SOU 2014:49, challenges or maintains a gender power order. This structure exists in the society and maintains men’s superiority to women and rein
Rapid urbanization has dramatically increased housing demand in Hanoi, the capital city of Vietnam. To alleviate housing shortage, the city of Hanoi has developed a housing program of which the major part is housing development through new urban area projects. New urban area, or new town, projects are large-scale developments designed mainly for residential purposes, with integrated infrastructure
