Design of inhalable mRNA therapeutics is promising because local administration in the respiratory tract is minimally invasive and induces a local response. However, several challenges related to administration via inhalation and respiratory tract barriers have so far prevented the progress of inhaled mRNA therapeutics. Here, we investigated factors of importance for lipid nanoparticle (LNP)-media
Remote sensing precipitation data have the characteristics of wide coverage and revealing spatiotemporal information, but their spatial resolution is low. The accuracy of the data is obviously different in different study areas and hydrometeorological conditions. This study evaluated four precipitation products in the Yellow River basin from 2001 to 2019, constructed the optimal combined product,
The purpose of this study was to investigate whether Södra Cell Mörrum, SCM, could invest in a steam turbine to produce profitable electricity from excess steam, which is currently being released into the atmosphere. Furthermore, this study investigated the potential side effects from this installation and suggests solutions. This study was conducted in two phases: collecting data which was then s
Human-induced climate change has emerged as one of the greatest sustainability challenges of our time, with significant risks for human health, livelihoods and security. However, technological solutions to phase out the use of fossil fuels in industrialized countries are politically contested. Their adoption depends on disrupting the institutions and behaviours that perpetuate the dependence on fo
This thesis evaluates the performance of an EPR programme for post-consumer PET waste management by PET recycling company (PETCO) in South Africa. It analyses waste management policies of South Africa that are relevant to EPR. Using a set of evaluative tools, the thesis reveals areas for improvement in the EPR scheme. It also identifies areas in informal sector interventions where EPR can contribu
Nature-based Solutions (NBS) are one of the approaches to the regeneration of urban areas. These solutions are copied from, inspired by, or supported by nature. The solutions, ideally, result in multiple benefits to the society and environment. The examples of NBS measures for stormwater management are, including but not limited to, natural swale, retention ponds, and green roofs. Such measures ha
Despite progress over the last decades, East Africa has one of the highest ratios of preventable maternal mortality in the world. This qualitative case study sheds light on Midwife-Led Care (MLC) in Ethiopia, Kenya, Malawi and Somalia. MLC is a model of care associated with improved health outcomes and enhanced utilization of health systems resources. Nevertheless, the model is not properly integr
Objectives: Multi-stakeholder partnership is garnering greater attention worldwide as a means of tackling global wicked problems, implementing sustainable development and leveraging development cooperation. By adopting meta-governance approach, this study investigates the case study of Hoi An - A Green Destination partnership in the waste management context of Hoi An city, Vietnam to understand ho
Electric cars are by many considered a sustainable solution to the ever-growing demand for road vehicles and fuel. The transportation sector is responsible for almost a third of the total greenhouse gas emissions globally and approximately 80% of these emissions can be attributed to road vehicles. Thus, there is an urgent need for a shift away from fossil fuels in the sector. While the consumer in
This thesis evaluates the effect of Chinese Foreign direct investment (FDI) on exports and imports for the five African countries: Angola, Nigeria, South Africa, Zambia and Zimbabwe using the gravitational model. The gravitational model will analyze how both inward FDI investments and Chinese investments impact import and export by using a sample of 166 partner countries over the period 2003-2012.
As Special Purpose Acquisition Companies (SPACs) are becoming the increasingly popular method of taking a company public, the lack of research on abnormal returns for this asset class since its introduction to the major exchanges validates a reason to expand the investigation. This thesis examines the potential abnormal returns found in different stages of recent SPACs lifecycle, dividing the SPAC
PFAS (per- and polyfluoroalkyl substances) are a group of synthetically manufactured chemicals contributing to environmental pollution. The largest point source of PFAS in Sweden is the usage of firefighting foam, and at MSB (Swedish Civil Contingencies Agency) Revinge, firefighting foam has frequently been used. Moreover, PFAS is known to accumulate in plants, and a Salix plant cultivation has be
Decarbonising hard-to-abate sectors such as the steel industry presents a major challenge for the European Union and its member states. These sectors must reduce emissions while maintaining global competitiveness, placing considerable pressure on both industry actors and policymakers. One proposed solution is the development of green lead markets, which aim to lower investment risks by enabling ma
This study analyzes the implications of nature-based solutions (NBS) for women in the Gambia, in flood prone communities in the context of the Rural Integrated Climate Adaptation and Resilience (RICAR) project. Employing a mixed-methods approach, including surveys and focus group discussions, the thesis investigates gendered differences with the guiding research question “How do nature-based solut
This thesis explores the correlation between green transitions and green gentrification, using the case study of the Western Harbour in Malmö, Skåne. More specifically, through the lens of the Right to the City and Environmental Justice, this thesis looks into the accessibility to green spaces in the Western Harbour for different socio-economic groups. Expert interviews, qualitative surveys with r
A search is performed for dark matter particles produced in association with a resonantly produced pair of (Formula presented)-quarks with (Formula presented) using (Formula presented) of proton-proton collisions at a center-of-mass energy of 13 TeV recorded by the ATLAS detector at the LHC. This signature is expected in extensions of the standard model predicting the production of dark matter par
Micropollutant removal is a key component of the revised Urban Wastewater Treatment Directive (UWWTD) and can be achieved with ozonation. During ozonation, the composition of the wastewater matrix and the targeted treatment level for individual micropollutants or groups of such compounds affect ozone consumption. In this work, it was hypothesized that nitrite scavenging, the point of dosing (befor
A search for T and Y vector-like quarks produced in proton-proton collisions at a centre-of-mass energy of 13 TeV and decaying into Wb in the fully hadronic final state is presented. The search uses 139 fb−1 of data collected by the ATLAS detector at the LHC from 2015 to 2018. The final state is characterised by a hadronically decaying W boson with large Lorentz boost and a b-tagged jet, which are
Hydraulic balancing is key to ensure proper operation of the heating system. When the heating system is not hydraulically balanced, heat is unevenly distributed across dwellings resulting in a wide temperature spread, overheating, and consequently, wastage of energy. In this paper, we study to which extent hydraulic imbalance affects the thermal energy demand of buildings. Furthermore, key variabl
