Visual requirements are high when sorting mail. The purpose of this visual ergonomics intervention study was to evaluate the visual environment in mail sorting facilities and to explore opportunities for improving the work situation by reducing visual strain, improving the visual work environment and reducing mail sorting time. Twenty-seven postmen/women participated in a pre-intervention study, w
Fair use is a doctrine native to the U.S., but is with the introduction of the internet more than a decade ago now informally applied worldwide. It has become a potent tool for the digitisation of classic content, such as books and music. In a very debated area of law, copyright is now regarded not as a promotional tool for intellectual endeavours, but as a brake block obstructing the development
During many of the lectures this spring we have heard how important and essential a social secretary can be for the youngsters they come in contact with. We therefore thought that it would be interesting to investigate how this works in reality. The purpose of the thesis was to investigate young girls own experiences of contact and their relationship with their social secretary whilst they were in
Stress is a growing problem in society and has been for many years. Different ages and different occupations experience different amounts of stress in their day-to-day life. This quantitative study focused on surveying how social work students perceived stress affects their lives on a day-to-day basis. Another focus was to determine whether there are connections between the students' perceived
This essay discusses the Nordic region Bohuslän the decade after it became "Swedish" in 1658, during what I call the region's "transition period". The wide cause of the study is to show how the traditional understanding of this state shift (and of state shifts in general) need to be problemized and understood in the light of the state conditions of Early Modern Europe. By e
En bristande närvaro kan för elever komma att innebära en risk för misslyckande i skolan och därmed även till negativa konsekvenser i senare livsskeden. Därför är närvaro en viktig del av elevers skolgång, mer specifikt en viktig förutsättning för en framgångsrik skolgång. Syftet med studien är att undersöka huruvida niondeklassares attityd till skolan samt motivation predicerar deras skolnärvaro A lack of attendance for students may mean a risk of failure inschool and thus also of negative consequences in later stages of life. Therefore, attendance is an important part of students schooling, more specifically an important prerequisite for a successful schooling. The current study aimed to investigate whether ninth-graders’ attitude to school and motivation can predict their school attenda
This thesis explores the classification of savannah trees using EnMAP hyperspectral and Sentinel-2 multispectral satellite data using a Random Forest classifier. The study aimed to assess if the increase in spectral information from the hyperspectral data gives an increase in classification performance, to find the advantages and limitations to hyperspectral data compared to multispectral data and
I samband med utbildning inom digitala verktyg samt VFU kopplat till EDI väcktes intresse att undersöka vilka kunskaper som behövs för att undervisa i dator som instrument samt vad som ingår inom InSå-undervisning för en EDI:st på estetiska programmet. Detta resulterade i tre forskningsfrågor relaterade till EDI-undervisning på gymnasieskola: (i) Vilka ämneskunskaper inom EDI anser EDI-lärare behöIn relation with education regarding digital tools as well as internships related to EDI an interest was developed in researching what subject knowledge is needed in teaching this instrument, as well as what teachers incorporate in their instrument lessons on a high school level. Three research questions emerged from this in relation to primary instrument teachings on a high school level: (i) What
This thesis investigates how people who have experienced loss, reason about grief, death and AI-mediated posthumous communication in contemporary digital culture, using the episode Be Right Back from the well-known TV series Black Mirror as a shared point of reference. Given the rapid development and everyday normalisation of generative AI, griefbots and other forms of simulated companionship, the
At the SCA papermill in Obbola byproducts from the pulp- and paper production are incinerated together with purchased wood fuels to produce steam in Ångcentral 2 (Steam centre 2). As the boiler was built for other types of fuel there are currently problems with both emissions and corrosion. Earlier studies, on other boilers, indicate that dosing sulphur could help solve some of these issues. This
A total of 24 UAV flights in the vicinity of integrated sensing and communications-enabled (ISAC) antenna systems, called base stations, were selected to investigate whether tracking can be improved using machine learning methods. This was done by inputting time series of range-Doppler (r-D) maps created from continuously calculating channel estimates of the bistatic environment around base statio
The production of TMP (Trimethylolpropane) is important for many applications, and is used as alkyds in paint and lubricants among others. The reactions producing TMP consist of two major reaction chains, Aldol condensation and Cannizzaro reaction. To get a deeper understanding and improve the running conditions the kinetic expressions for the reactions were examined. The aim of this paper was to
In 1961 a concrete wall through the city of Berlin was erected and further determined the division between a once united Germany into West and East Germany. In East Germany the communist party had the power and the newspaper Neues Deutschland to spread its propaganda, until the fall of the Berlin wall in 1989. The aim of this paper is to look further into how the newspaper Neues Deutschland portra
“Many just wait for someone to dare to ask.” – A study about social workers reflections on addiction and sexuality [translated title] The purpose of this study was to examine if and how social workers with experience of treatment interventions reflect about the supposable correlation between addiction and sexuality. Five qualitative semi-structured interviews were conducted with social workers wh
BACKGROUND: Retrospective studies have shown promising results using artificial intelligence (AI) to improve mammography screening accuracy and reduce screen-reading workload; however, to our knowledge, a randomised trial has not yet been conducted. We aimed to assess the clinical safety of an AI-supported screen-reading protocol compared with standard screen reading by radiologists following mamm
Background: The CREST model is a prediction model, quantitating the risk of circulatory-etiology death (CED) after cardiac arrest based on variables available at hospital admission, and intend to guide the triage of comatose patients without ST-segment-elevation myocardial infarction after successful cardiopulmonary resuscitation. This study assessed performance of the CREST model in the Target Te
[4Fe–4S] clusters are essential cofactors in many proteins involved in biological redox-active processes. Density functional theory (DFT) methods are widely used to study these clusters. Previous investigations have indicated that there exist two local minima for these clusters in proteins. We perform a detailed study of these minima in five proteins and two oxidation states, using combined quantu
In chemistry education, student learning difficulties involve connecting theory and phenomena to make sense of chemistry, as well as utilising and understanding the language of chemistry. In this thesis, I examine the relationships among student language use, previous achievement level, and sensemaking in chemistry, as well as how experienced teachers help students make sense of chemistry as part
