Bakgrund och syfte: Det råder olika uppfattningar kring rödhårigas respons på smärta och behov av analgetika och hypnotika inom forskning och klinik. Forskning som studerat rödhåriga personers respons på hypnotika har visat varierande resultat där behovet har varit både ökat och minskat. Vissa menar även att rödhåriga personer har en högre smärttröskel och mindre effekt av analgetika medan andra sBackground and purpose: There are different perceptions about redheads' response to pain and their need of analgesics and hypnotics, both within research and clinical practice. Research that has studied redheads’ response to hypnotics has shown varying results where the need of such both has increased and decreased. Some people go as far as to say that redheads have a higher pain threshold and

Job satisfaction is a complex concept that has mainly been investigated in a quantitative nature from several perspectives. Most past studies have focused solely on investigating full-time employees quantitatively, without taking into account other employment types such as part-time student employees, or other methods of data collection. Additionally, a lack of studies exist focusing on comparing

Kriminalpolitiken och det stigande gängvåldet var bland de mest diskuterade frågorna inför valet 2022 i Sverige. I syfte att lösa dessa problem sökte politiker och media vägledning i den danska lagstiftningen. Efter valet ingicks Tidöavtalet, en partiöverskridande överenskommelse i syfte att bilda regeringsunderlag. I avtalet föreslogs en kriminalisering av deltagande i kriminella gäng. Uppsatsen The criminal policy and the rising gang violence were among the most debated issues leading up to the 2022 election in Sweden. In order to address these problems, politicians and the media sought guidance from Danish legislation. After the election, the Tidö Agreement was concluded, a cross-party agreement aimed at forming a government coalition. The agreement proposed the criminalization of parti

Den 1 Juli 2021 trädde ett flertal ändringar i föräldrabalken i kraft. En av ändringarna tog sikte på vad domstolen särskilt ska beakta i vårdnadstvister, vid avgörande om vårdnaden ska vara ensam eller gemensam. Domstolarna ska enligt 6 kap. 5 § andra stycket föräldrabalken lägga särskild vikt vid föräldrarnas förmåga att sätta barnets behov främst samt ta ett gemen-samt ansvar i frågor som rör bThe first of July 2021 several changes of the Swedish parental code came into force. One of the changes regarded what the court should pay special attention to in custody disputes when deciding if the custody should be sole or joint. According to 6 Ch. section 5 second paragraph in the Swedish pa-rental code, the courts must especially consider the parents’ ability to put the child's needs fir

The application of digital twins in the city setting is emerging, the massive amounts of data and algorithms used raise the concern of algorithmic bias. This research focuses on examining how city scale digital twin practitioners prioritize the pragmatic, ethical, and moral domains in data management processes and when encountering algorithmic bias. It aims to provide insights for practitioners an

The aim of this study was to evaluate two methods of detecting a difference in activity between the two hemispheres of the brain when presented with stimulus during memory encoding. The difference intended to be detected was based on the lateralization of brain processing of sensory input, which was triggered by an auditory stimulus in one ear at a time. The methods that were used for detection, c

Aquaculture is an expanding industry, supplying closer to 50% of the total fish consumption. Commercialized fish production faces sustainability challenges which are important to address. Aquaponics uses wastewater from aquaculture to grow plants using hydroponics. This is a step towards making the industry more sustainable, but the practice is not straightforward. The plants and the fish thrive a

Introduction: Wood packaging consumes over twenty percent of industrial timber harvests in the United States. Organised reuse of wood packaging can reduce timber consumption but is not widely practised. Existing research on circular wood packaging systems is limited in scope, focusing on individual design and process interventions at the firm level. This thesis constitutes a novel investigation o

Ny avfallslagstiftning tvingar kommunerna att se över sina avfallsabonnemang I dagsläget bestämmer varje kommun själv hur många källsorterade avfallsfraktioner de vill hämta upp hos hushållen samt huruvida matavfall ska sorteras ut separat eller slängas blandat med restavfall. Ny avfallslagstiftning från EU och regeringen tvingar kommunerna att se över sina avfallsabonnemang så att de lever upp tRecycling reduces the need for new raw materials and greenhouse gas emissions. In addition, the new waste legislation from the EU and the Swedish government imposes higher recycling requirements on Swedish municipalities. Starting from January 1, 2024, it will be mandatory for all EU member states to separately collect food waste through curbside collection. The Swedish government has also decided

Bygg- och servicesektorn står idag för mer än en tredjedel av Sveriges totala energianvändning. Energifrågan ligger i fokus och samhället strävar efter en mer hållbar utveckling. Samtidigt ökar elpriserna vilket lämnar många hushåll med dyra räkningar för uppvärmning av sina småhus. En stor del av Sveriges småhus byggdes under 70-talet i samband med miljonprogrammet. Villabyggandet var som mest The construction and service sector currently accounts for over one-third of Sweden's total energy consumption. Energy issues are at the forefront, and society is striving for more sustainable development. At the same time, electricity prices are increasing, leaving many households with expensive bills for heating their houses. A significant portion of Sweden's houses were built during th

Healthcare systems around the world are facing a multitude of challenges, mostly because of aging populations. The Covid-19 pandemic put further strain on the sector and has left many countries with a backlog of medical procedures, which further exacerbates the issues. New technological products and solutions are one way to relieve healthcare workers and enable more efficient care. Zymego is a com

Palsa mires are typical wetland landscapes of the Arctic regions, consisting of mosaics of palsas (raised formations of peat and permafrost) and shallow ponds, all embedded in wet mires. These heterogeneous habitats support rich and abundant wader populations, which breed there during the short Arctic summer. Although being threatened by climate change, relatively little is known about the ecologi

Preterm birth is a leading cause for birth complications and neonatal mortality in the world. It remains difficult to predict whether a preterm birth will occur, which hinders the possible use of prevention treatments. This thesis investigates the use of machine learning models in the prediction of spontaneous preterm birth. In addition, possible heterogeneous performance of these models among dif

Particle size can be an important variable to know in many different areas, be it smoke simulations, toxicity of materials or tests of face masks. Fires in a reduced oxygen environment can occur for ventilation-controlled fires or in areas with artificially lowered oxygen levels. The effects of lower concentrations of oxygen on heat release rate, smoke production etc. has been studied, but any eff

Strålterapi är en vanligt förekommande behandling som ges till hälften av cancerpatienterna i landet. I fallet för prostatacancer, som utgör den vanligaste diagnosen, beror ofta cancerrelaterade dödsfall på återkomst av sjukdomen efter genomförd behandling. Vår hypotes är att detta kan minskas genom att identifiera strålrestistenta volymer i prostatan och öka stråldosen till dessa. Tyvärr finns deRadiotherapy is commonly used for cancer treatment, given to approximately half of all cancer patients in Sweden. Despite its widespread usage, there is currently no non-invasive and reliable imaging method that can identify regions of radiation resistance. These regions may be identified by hypoxia, given that radiobiological research has demonstrated a significant correlation between oxygen leve

Under de senaste årtiondena har bin, såsom humlor, minskat i både antal arter och populationsmängder. Detta är ett stort problem för vårt samhälle då både jordbruket och naturliga ekosystem till stor del är beroende av dessa pollinatörer. Det är speciellt problematiskt att humlor minskar då de har förmågan att utföra en speciell sorts pollinering (buzz-pollination) som några av våra vanligaste gröThe decline of bees, such as bumblebees, over the last decades raises concerns as they are key pollinators in both agricultural and natural ecosystems. One proposed cause for the decline of wild bees is competition for food resources with managed honeybees. Detrimental effects of competition can result where co-existing species exhibit a high degree of shared resource use (i.e., niche overlap). Th

The majority of the coastal area of Scania is highly susceptible to sediment transportation. Due to various influences which are both human induced and natural, the morphology of coastal dunes often alters. Therefore, it is important to assess these changes, especially after major cyclonic storms such as the storm Babet in order to get a comprehensive understanding of the aftermath. The purpose of

Risk perception and risk tolerance are key elements of decision-making and flight safety. During flight operations, an accident may occur if a pilot underestimates risk level or overestimates their capacity (risk tolerance). Despite the numerous research studies conducted previously on risk perception and risk tolerance, there has been limited investigation into the "evolution" of these
