Today, the most commonly used energy storage device in embedded systems is batteries. But unfortunately, batteries are associated with short lifetime. By introducing Electrochemical Double-Layer Capacitors (EDLCs) as an alternative power source, the lifetime of the backup energy source can be significantly increased. The lifetime is dependent on two predominant factors; temperature and voltage. T
As a stage in the development of the next generation of wheel loaders, all systems are evaluated in order to minimize the energy consumption. This master thesis aims to investigate the energy consumption for four linkages with different design. It will also investigate how the energy consumption changes when an electro-hydraulic compensation is added in order to keep the load parallel and what the
This study evaluated the performance of a new lignin-based activated carbon (AC) for the removal of per- and polyfluoroalkyl substances (PFAS) from contaminated groundwater from Korsør, Denmark. Preliminary tests using 14C-labeled PFOA and scintillation counting were conducted to compare adsorption capacities of three lignin-based AC variants and a commercial AC (Norit BAE Super), guiding the sele
The Andes of Ecuador are known for an outstanding biodiversity but is also a region where the abandonment rate of agricultural land is high, highlighting the need for forest restoration with native species. Here, the germination and growth requirements for propagation of the hummingbird pollinated bush species Salvia corrugata and Macleania rupestris were studied to better understand their suitabi
Plastic pollution is a severe global problem and every year approximately 368 million tons of plastic is produced. Both terrestrial and marine environments are impacted and hundreds of species affected. Marine plastic debris accounts for a weight of 268 940 tons and affects hundreds of marine species through habitat degradation, entanglement and ingestion. Microplastics (MPs) are a type of plastic
Within Social Work in Sweden, there has been a long-established tradition to work cooperatively across organizations to achieve various preventive measures, for instance with juvenile crime issues. The purpose of this study was to investigate how such cooperation across two organizations - the police force and the social services- is perceived by the professionals involved in practice. The method
The aim of this study has been to explore the perceptions of evidence-based practice among social workers along with how they perceive their prerequisites for working according to the evidence-based model. The social workers have been found within the children and family unit of the Swedish social services, and the evidence-based model was compared to that of the Swedish National Board of Health a
The aim of this study was to get an understanding of preschool teacher’s approach when they suspect maltreatment of a child. We wanted to know which factors affects if the preschool teachers report their concern to the social services or not and what routines preschools have for these situations. To do this we held semi structured interviews with six preschool teachers operative in both public and
Hirschsprung’s disease is a rare, congenital disease characterized by a lack of nerves in parts of the gastrointestinal tract. The disease is often diagnosed early in a child’s life, as the lack of nerves inhibits the passing of stool. Surgery is required to remove the affected part of the intestine. Today intra-operative biopsies are taken to determine where the diseased part of the intestine end
Over-indebtedness is at an all-time high in Sweden. The purpose of this study was to find relationships between financial literacy, the three coping behaviours: problem-focused, emotion-focused and avoidant, and personal payment strategies. A further aim was to find gender and generational differences in this objective. The study is a cross-sectional survey where the participants (N = 2057) answer
Antimicrobial resistance is a growing global health threat, and once curable infections are now becoming life-threatening. Still, the discovery of new antibiotics continues to decline. Targeted protein degradation potentially offers a novel antibacterial strategy by leveraging cellular degradation pathways to eliminate bacterial proteins. BacPROTACs represent a promising approach, as they utilize
Detta examensarbete utvecklar fram en skräddarsydd prototyp av en tillgänglig kommunal webbplats. Det innebär en kommunal webbplats som är anpassningsbar och lätt att navigera, speciellt för användare som tar hjälp av tillgänglighetsverktyg för att utforska webben. För att kunna ta fram denna prototyp, utvecklades först två prototyper som var nära besläktade. Dessa två prototyper jämfördes sedan This thesis project brings forth a tailored working prototype of an accessible municipal website. This means a municipal website that is adjustable and easy to navigate, especially for users in need of accessibility tools to browse the web. To create this prototype, we first created two separate prototypes that closely resembled each other. These two prototypes were then compared to each other and
Per- and polyfluoroalkyl substances (PFAS) are a group of highly persistent synthetic chemicals that have raised growing concern due to their widespread presence in the environment and potential health effects. This study focuses on Lake Bolmen, one of southern Sweden’s most important sources of drinking water, and investigates how PFAS enter and accumulate in the lake. A total of 23 PFAS compound
Author: Malin Glimhed Title: Not just a picture (translated title) A qualitative study about the way the art therapists work with children. Supervisor: Staffan Blomberg The aim of this study is to give knowledge to the role of painting in art therapy with a child. I have south a greater understanding of how the art therapist chooses to work with the child. To achieve the purpose I have focused o
The purpose of this essay has been to explore the contribution of pupil assistant to children with need of special support at school. My questions were: - When does the principal of the school consider that special needs exist? - What particularly needs requires getting the support of a pupil assistant? · How is the organisation structured and which are the purposes with the support? - Which metho
The purpose of my thesis was to examine the conscious and unconscious role of compulsory school in drug prevention work. I considered five topics: objective, methods, environment/relations, sender and target group. Essential questions within the topics were: What elements in compulsory school work preventive on children's drug use? What are the possibilities of reinforcing drug prevention work
The intention of this master thesis is to model the internal flow of an Alfa Laval course Filter with 20 cm inlet and normal outlet (ALF20), which is an automatic self cleaning filter aimed to rinse the cooling water upstream the inlet of a compact heat exchanger. Along the automatic cleaning process the ALF20 turn into a flushing and a back flushing operation mode. The ALF20 consists of a filter
Abstract Introduction: A great decline of wild pollinators has been observed, the decline is believed to be a result of many stressors, whereas pesticide usage being one of them. Wild pollinator insects are significantly important to maintain and preserve food production and biodiversity. Background: Pesticides are used to protect and enhance crop yield, by targeting insect and fungi pests. Imid
Statistical modelling could be included in a betting strategy where the value of a bet is assessed by comparing model predictions and market odds. This thesis presents several models based on statistical learning methods for predicting the total number of corners in a football match. Generalised linear regression and decision tree models were developed and their profitability was examined by using
OBJECTIVES: Apolipoproteins affect development of atherosclerosis, but their involvement in the pathogenesis of critical limb ischemia (CLI), a severe form of atherosclerosis, has not previously been examined. DESIGN AND METHODS: ApoA-I, apoB, and apoM were measured in plasma from 196 CLI subjects and 214 control individuals from the background population. RESULTS: Cases had lower levels of the ap
