Most countries in Sub-Saharan Africa have made great strides towards more accessible and higher quality schooling and medical systems in recent years. Despite this, education and health care in Africa lag behind other developing regions and large inequalities in educational levels and health care access remain across countries, subnational regions, and gender. Cameroon, in west-central Africa, wit
Background and purpose — Information on outcomes after some modern total ankle replacement (TAR) designs is scarce. We therefore examined outcomes after trabecular metal (TM) TAR in Sweden by use of data from the national registry. Patients and methods — On December 31, 2020, 239 primary TM TARs had been reported to the Swedish Ankle Registry. We analyzed prosthesis survival probability, using exc
Sufficiency has long been marginalized in the public and political sustainability discourse. Since attempts to reduce CO2 emissions in the long term have so far fallen short of expectations, sufficiency has recently approached the forefront of scientific and social debates about a »good life«. In addition to a strict reduction target, the sufficiency strategy promises psychological well-being and
The aviation sector is facing a massive change in terms of replacing the currently used fossil jet fuels (Jet A, JP5, etc.) with non-fossil jet fuels from sustainable feedstocks. This involves several challenges and, among them, we have the fundamental issue of current jet engines being developed for the existing fossil jet fuels. To facilitate such a transformation, we need to investigate the sen
The use of conventional fertilizers is associated with pollution due to leaching and a mismatch between release rates and crop requirements for optimal development. Slow-release fertilizers could address both problems. Here, the synthesis and properties of a zinc fertilizer composed of cellulose microbeads loaded with aqueous ZnSO4 are reported for the first time. UV-vis spectrophotometry showed t
Sustainability of the enterprise is crucial to support long-term business survival and development. Unpredictable events such as Covid-19 highlights sustainability issues in enterprises. This empirical study aims to investigate sociotechnical sustainability in real world work practices. The focus is on employee involvement and problems in work practices concerning the economic, environmental, soci
The response of clouds to the changes in climate is uncertain, and the representation of the cloud-climate feedback is a key challenge in the global circulation models (GCM) for future climate projections. Factors contributing to this uncertainty include processes that involve particles of various sizes and phases, as well as the interactions between these particles and the surrounding atmosphere.
Core–shell structural ZnSeTe/ZnSe/ZnS quantum dots (QDs) have attracted great attention for advanced illumination and displays because of their environmentally friendly composition, but still suffering from poor photoluminescence (PL) and electroluminescence (EL) performance due to severe non-radiative charge recombination. Herein, a stepwise injection shell growth process to manipulate the monome
We report a detailed density functional theory and molecular dynamics study of hydrogen bonding between trehalose and water, with a special emphasis on interactions in the amorphous solid state. For comparison, water-water interactions in water dimers and tetramers are evaluated using quantum calculations. The results show that the hydrogen bonding energy is dependent not only on the geometry (bon
Water pollution from industrial or household waste, containing dyes from the textile industry, poses a significant environmental challenge requiring immediate attention. In this study, we have developed a crosslinked-smart-polymer film based on 2-(dimethylamino)ethyl methacrylate copolymerized with other hydrophilic and hydrophobic commercial monomers, and its efficacy in removing 21 different tex
This thesis explores how contemporary Swedish Jews narrate their experiences of antisemitism. A central aim is to examine if and how the narrative norm of the cultural Holocaust memory – as formulated by Zoe Waxman – is reflected in present-day narratives of antisemitism. To make possible, the study employs a narrative discourse analysis. The findings suggest that the narrative norm of cultural Ho
Följande uppsats analyserar det straffrättsliga ansvaret vid olyckor orsakade av självkörande fordon. Dessa självkörande fordon styrs av avancerade artifi-ciella algoritmer som fattar autonoma beslut, vilket utmanar straffrättens grundläggande krav och principer. Bland annat blir maximet ”nulla poena sine culpa” (inget straff utan skuld) lidande när beslutsprocessen i gärningsögon-blicket saknar tThe following thesis analyzes criminal liability in accidents caused by self-driving vehicles. These autonomous vehicles are governed by advanced artifi-cial algorithms that make autonomous decisions, which challenges the funda-mental requirements and principles of criminal law. Among other things, the maxim "nulla poena sine culpa" (no punishment without guilt) suffers when the decision
Aim: This paper aims to describe what constitutes good-quality, accessible, affordable and acceptable primary care for migrants. This includes identifying system adaptations and offering evidence- and practice-based recommendations and guidance for primary care organizations and professionals on how to deliver such care.Background: Migration has significantly diversified European populations. Migr
The most prevailing hypothesis regarding mechanisms behind specific language impairment today is the hypothesis of general limitations of processing capacity. Such an hypothesis can hardly be tested by available language assessment tools, especially not by instruments in use for clinical assessment of the lexical-semantic domain in children. Reduced naming speed is by some researchers considered a
Corrosion of prestressing steel in post-tensioned (PT) cables is a critical issue in prestressed concrete bridges, often leading to brittle and unexpected failures. This deterioration is primarily attributed to construction flaws such as inadequate grout injection and the use of poor-quality mortar. This paper presents a probabilistic model for estimating the number and spatial distribution of gro
This thesis examines the ejido system in Mexico in order to understand the dynamics of land tenure, governance and transaction costs through the lens of Elinor Ostrom’s theory of good governance. This case of the ejido system was chosen as their constitution that enabled a communal access land tenure regime in the agricultural sector, was amended to allow for privatization. The ejido serves as a p
Pelare som utsätts för tryck kan behöva stabiliseras för att inte böja ut oönskat mycket i sidled. För att stabilisera pelaren måste fjäderstyvheten i det stabiliserande stödet vara tillräckligt stort. Detta för att undvika instabilitetsbrott men också för att fjäderkraften i stödet inte ska bli för stor. För en pelare med en led i toppen och i botten beräknas vanligen Eulers knäckningslast P_e=(Columns under vertical point loads will need a brace in order not to bend out in a mode of column buckling. To stabilize the column, a sufficient brace stiffness needs to be given, both to avoid column instability and to reduce the horizontal force which occurs in the brace. Column buckling is usually determined by Eulers buckling formula P_e=(π^2 EI)/l^2 . This is the value when buckling occurs r
Denna mastersuppsats tar fram en metod för att automatiskt hitta och rita ut höger hjärtkammare i datortomografibilder. Hjärtat är ett av kroppens mest vitala organ där en liten störning kan leda till ödesdigra konsekvenser. Med detta i åtanke är det inte konstigt att hjärt- och kärlsjukdomar är den vanligaste dödsorsaken i världen. Det är på grund av detta som forskningsprojekt likt SCAPIS har vuUsing cardiac computed tomography (CT), images of both the left and right ventricle can be acquired. Potential findings of interest are for example enlarged ventricles or inadequate pumping, which can be used for diagnosis. The analysis requires that the ventricles are outlined, either manually or automatically. Automated segmentation methods for clinical use exist for the left ventricle but not f
