The lignin-inspired derivatives coniferyl aldehyde and sinapyl aldehyde were used to prepare nitrile-containing methacrylate monomers with the aim to synthesize bio-based polymers exhibiting high glass transition temperatures (Tgs). The aldehydes were initially transformed to the corresponding nitriles and then underwent methacrylation before being polymerised by free-radical polymerisation. The h
The dimensions of cultural economics have been more and more discussed recently. This study aims to analyze the relationship between social tolerance and economic growth. Previous studies have discussed two main ideas. Firstly, social tolerance creates a creative environment that promotes innovation and entrepreneurship. Secondly, social tolerance lowers barriers to entry in human capital accumula
Detta examensarbete, utfört i samarbete med ASSA ABLOY Entrance Systems, syftar till att utveckla en ny ramsektion för industriella takskjutportar. Takskjutportarna är en del av den befintliga produktportföljen och finns i två olika tjocklekar, 42 och 82 mm. Dörrarna är uppbyggda av antingen panel- eller ramsektioner, eller en kombination av båda. Den 82 mm tjocka dörren används när det finns ett This Master Thesis, executed in collaboration with ASSA ABLOY Entrance Systems, aimed at developing a new frame section for industrial overhead sectional doors. The overhead sectional doors are a part of the existing product portfolio and exist in two different thicknesses, 42 and 82 mm. The doors are built up by either panel or frame sections, or a combination of both. The 82 mm thick door is use
The main focus of this thesis is to study Hall’s Marriage Theorem, which was named after, and proven by the English mathematician Philip Hall in 1935 [6]. The theorem can be stated in terms of different mathematical fields and there are several equivalent theorems proven by other mathematicians [3]. This thesis is mainly going to focus on the graph-theoretic formulation. When stated in terms of gr
Syfte: Studien syftar till att få en djupare förståelse för på vilket sätt sociala medier influencers uppfattas som förtroendeingivande i ett konsumentperspektiv. Frågeställningar: De frågeställningar som ligger till grund för uppsatsen är: - Vilka fundamentala faktorer hos en influencer skapar förtroende i samband med reklamsamarbeten på Instagram ur ett konsumentperspektiv? - Varför inger dessa
This paper evaluates the impact of reproductive health care restrictions on women’s labor market outcomes in the United States. We exploit the variation in restrictions on reproductive health care services across U.S. states and over time by using individual level data on fertility and labor market outcomes and state level data on reproductive health care restrictions. We apply a difference-in-dif
Artificial neural networks are prone to overfitting – the process of learning details specific to a particular training data set. Success in preventing overfitting through combining the L2 and dropout regularisation techniques has led to the combination’s recent popularity. However, with the introduction of each additional regularisation technique to an artificial neural network, there comes new h
The purpose of this study is to examine and investigate what the norm-setting process looks like in regards to regulations that give employers the opportunity to request and demand drug tests from their employees. To fulfill the purpose of the study, a qualitative research method with semi-structured interviews were conducted. The sample consisted of employers and union worker representatives. Fur
The aim of this study was to investigate how nurses and counselors at an outpatient clinic in cancer care experience working with children as next of kin. This was done by examining how the nurses and counselors describes working with children who have a seriously ill parent. The study was conducted through semi-structured interviews with four counselors and three nurses from two oncology clinics
Earning conference calls is an important communication tool for companies to provide relevant information about the latest quarter based on the reported earnings. However, the research on the impact of the earning conference calls has for long been a relatively unexplored subject. This study was born out of the ambition to try and expand the research done on earnings conference calls and the possi
I examine a favourite child's effect on educational attainment and mental and physical health and well-being. In the favourite child effect, based on parental preferences in the sex composition of children using a proxy for parental investment, I can assess how parents distinguish inputs based on the sex of their children. Identification utilising data from three longitudinal studies in the Un
The world's elderly population is growing and the future home care is facing great challenges to cover the need of home care that will be required. Digital technical equipment plays a key role in modern health care and can be important to overcome the challenges in the future home care. A challenge that has been discovered within Helsingborg’s home care is that patients are worried about when
In the early 21st century, deflationary trends applied pressure on margins in a range of different industries and subsequently cost reductions were required. Improving efficiency in the supply chain was identified as one of the key sources of potential cost savings. Subsequently, a trend towards slimmer supply chains with less stockkeeping emerged. However, due to the covid-19 pandemic supply chai
The aim of this study was to investigate how social workers reflect on municipal activation for clients who receive financial assistance, and the boundaries the social workers set in regard to the Swedish Public Employment Service. The aim is also to analyze which activation measures are used in the municipality, why they are used and how the social workers use their discretion in decision-making.
The aim of this study was to examine the significance of psychosocial work and perspective in addiction care within the Swedish healthcare system and what it is that enables or limits healthcare counselors’ psychosocial work in the medical context. The methodology is based on a qualitative approach using eight semi-structured interviews with healthcare counselors working with addiction care in the
The purpose of this study is to provide a more profound knowledge of how routines impact creativity when studying a Symphony Orchestra. This includes the exploration of obstacles hindering individuals to be creative as well as enabling factors that enhance creativity within the context of routines. Following an interpretivist tradition, our qualitative study uses an abductive approach to a single
Studien fokuserade på proteinet “galectin-8N”, vilket är ett lectinprotein av betydelse för vissa kroppsliga funktioner som till exempel inflammation, autofagi och cellmigration. Arbetet omfattade tre delmål: 1. att kristallisera två varianter av mänskligt galectin-8N och öka dess reproducerbarhet; 2. att studera bindningar och interaktioner mellan bindningsställen för humana proteinerna och tre sThis thesis focuses on the protein “galectin-8N” which is a lectin protein that takes part in several physiological functions such as inflammation, autophagy, cell migration, and more. The project has three objectives: to observe and increase the reproducibility of crystallization of two variants (wildtype and mutant) of the human protein galectin-8N and to analyze the binding site when three diff
In life-threatening conditions in the vessels of the brain, neurointervention can be the treatment that saves lives. With only one incision in the vessel of the groin, a catheter can be navigated to the affected vessel and treatment can be performed using tools inserted through the catheter. In this report, a training model for neurointervention consisting of interconnected vascular models has be
Universum tros ha en diameter på kring 93 miljarder ljusår. Det är därför svårt att tänka sig att hela universum en gång i tiden fick plats i en enda punkt för 13,8 miljarder år sedan. Sen kom den stora smällen! Det som följde var troligen en kort period av väldigt snabb expansion. På samma sätt som ett jetplan som accelererar förbi ljudvallen resulterar i en ljudbang, borde den snabba expansionenIn this thesis, the consequences of introducing Yang-Mills fields into cosmology are investigated. This is done by the effective action approach, in which the coupling constant is allowed to depend on the quantum fields. The equation of state and scale factor are then found for the flat universe filled with either chromoelectric or chromomagnetic fields. From this, we draw conclusions about the hi
