Amid an anthropogenic sixth mass extinction, amphibians are among the most threatened organism groups. This can be explained largely by the loss and fragmentation of natural wetlands due to agricultural activities and urbanisation. Stormwater retention ponds are designed both to provide flood control and to collect and purify runoff from impervious surfaces but could also serve as amphibian habita
Microcystis blooms are implicated in toxic algal blooms worldwide due to the production of toxins microcystins. Blooms have caused poisoning of humans and other animals, and annually contribute to economic loss. The biological role of microcystin synthesis by the genus Microcystis remains an unanswered question. Consequently, the factors that select for microcystin producing (toxic) phenotypes ove
Alkaline exchange membrane fuel cells (AEMFC) is an interesting and attractive alternative to proton exchange membrane fuel cells (PEMFC) due to the potential use of non-precious catalysts which can reduce the overall cost of the fuel cell. An important component of the AEMFC is the anion conducting membrane. This membrane needs to possess several important properties such as a high hydroxide cond
Texter är en ofrånkomlig del av många museiutställningar och har till uppgift att ta det obekanta och avlägsna närmare besökaren. Denna undersökning utforskar hur texter i Nordiska Museets utställning “Arktis – medan isen smälter” gör för att förmedla det komplexa och svårgreppbara ämnet klimatförändringar till sina besökare. Metoden kombinerar interpersonell analys som beskriven i Lennart Hellspo
This study examines if inhabitants of different municipalities in Sweden are more harshly affected given an increase in gasoline tax. This is done by examining the demand elasticities and consumer surplus loss using a panel Error Correction Model. The results show that inhabitants of rural municipalities are more unresponsive and lose out more consumer surplus from a hypothetical increase in the t
Cost benefit analysis is a valuable tool for making sustainable decisions in many sectors of society. This master thesis examines the application of cost benefit analysis for safety measures in infrastructure planning in Sweden with the aim to identify difficulties and possible improvements. This was accomplished by examining implemented cost benefit analyses and performing qualitative interviews
The construction workflow of in-situ concrete frames in multi-storey residential buildings is highly complex and dynamic. Discrete-event simulation (DES) offers capabilities to model and analyse such complexity. Although DES has successfully been used by researchers in a wide range of construction-related applications there are not many examples demonstrating how different simulation outputs (time
This report presents an integrated simulation-based approach to study the on-site production of concrete frameworks by considering the multiple effects of weather on work task productivity and concrete curing process. The suggested approach enable to systematically study how different weather conditions and the use of climate-improved concrete in combination with different methods to shield concre
Sustainability-driven businesses combine the principles of conventional for-profit companies with a strong commitment to their social and environmental credentials. This structure enables them to address social problems in an economically sustainable manner and to capitalise on consumer demand for responsibly-made products. The growth of sustainability-driven companies is often seen as another suc
Inledning och problembakgrund redogör för hur digitaliseringen förändrar både människor och organisationers praktiker och hur detta på olika vis påverkar handeln. Tidigare forskning på området har antingen fokuserat på servicearbetet eller på konsumenters och organisationers användning av teknologi. Treadgold och Reynolds (2016) tillsammans med Fuentes och Svingstedt (2017) tar upp digitaliseringe
The aim of this thesis was to compare different ways of dissociating tissue - specifically breast cancer tissue - and sorting out tumour cells and immune cells from the dissociated tissue using acoustophoresis in a microfluidic chip. Due to ethical issues with using tumour tissues to work on the methodology of a project, ultimately only healthy breast tissue was used in this work. Two dissociatio
The study investigates the design of kené, a geometrical pattern originated in the culture of Shipibo, in relation to Gilles Deleuze and Félix Guattaris’ philosophical term rhizome. Kené is, besides the nowadays more influential part of the Shipibo material culture of handicraft, historically connected to healing practices which includes the hallucinogenic brew ayahuasca. The thesis is an autoethn
Around 60 million people around the world are struggling with a traumatic brain or spinal cord injury. The swelling of the brain or spinal cord happen when the water content in the CNS increase due, infection, tumor growth or brain edema. AQP4 is a membrane water channel which mediates the water flux across the blood brain barrier (BBB) and blood spinal-cord barrier (BSCB). We believe that protein
This study assessed the work of individuals, organizations and the state in the promotion of women’s right to education after the Taliban regime in Afghanistan. It drew from the theories of feminism and masculinity as well as Feminist Security Studies and gender and development studies. In order to achieve its objective, the study adopted a triangulated research method which involved Discourse Ana
Museums today try to combat the exclusionary ground on which they were founded, with strategies of broader inclusion. In Århus, Denmark the Women’s museums vision is to be a museum for ”all genders”. In this thesis I investigate the approach to gender in the Women’s museum’s exhibition Køn Redelighed (eng. Gender Blender) (2017-2022), through a queer theoretic lense of gender as a hybrid and discu
This master thesis examined the microstructure after heat treatments in stainless steel, two conventional stainless steel (304 and 316) and two novel high temperature stainless steel. These stainless steels are for the use in high temperature heat exchangers for extended temperature range. The positive characteristics in stainless steel are inversely correlated to grain size, characteristics such
Utgångspunkten för studien är att undersöka allmänhetens ställningstagande kring förändringar inom barnavården under tidsperioden 1900 till 1950. Under denna tidsperiod skedde en övergång från att barnavården var en privat angelägenhet till att bli statlig. År 1937 beslutade riksdagen om att införa fri spädbarnsvård för hela landet, sedan sekelskiftet år 1900 hade liknande verksamhet bedrivits av
