Artros är en vanlig sjukdom som påverkar ett antal olika leder i kroppen. Den vanligaste av dessa är knäartros, som utgör omkring 85 % av alla atrosfall. Sjukdomen påverkar alla delar av leden, speciellt tydlig är effekten på ledbrosket som förtunnas och till slut bryts ner helt. Denna process kan leda till stora besvär, så som smärta och minskad rörlighet, men i nuläget finns mycket få behandlingBackground/purpose Quantitative susceptibility mapping (QSM) is an MRI-based post processing technique to evaluate the magnetic susceptibility, χ, of human tissue using phase data. While brain imaging has been the most common application, other areas have also raised interest. For example, QSM of the articular cartilage of the knee has been suggested as a means to study the degeneration of this ti

Av de 70 000 personerna som blev diagnoserade med cancer i Sverige 2021, fick runt 4000 lungcancer. Lungcancer är vanligen elakartade celler som utgår från lungans slemhinna. Behandling innefattar oftast operation eller strålterapi, ibland i kombination med cellgifter eller immunterapi. Inför strålbehandling gör patienten en röntgenundersökning som ger bilder i tre dimensioner, en så kallad datorPurpose: The purpose of this master thesis was to retrospectively investigate correlation between surface and tumour motion in lung cancer patients, alongside deep learning applications of the results. Additional correlations such as age, tumour volume and anatomical placement of the tumour were also investigated. Materials and Methods: 48 lung cancer patients treated with Stereotactic Body Radia

Stroke är när patienten får en blödning eller blodpropp i hjärnan som kan orsaka tal och rörelsebortfall, och i värsta fall en plötslig död. Åderförkalkning i halskärlen orsakar kring 10%−20% av alla stroke-fall. Den nuvarande metoden som används för att bedöma åderförkalkningen är att mäta förträngningen av blodkärlet i skiktröntgenbilder (3D-röntgenbilder). Förträngning av blodkärlet säger ingenIntroduction and aim Atherosclerotic stenosis located at the carotid bifurcation accounts for 10% − 20% of all Transient Ischemic Attacks (TIA) and ischemic strokes, which occurs when Atherosclerotic stenosis, or so-called plaque, ruptures. The current method to evaluate carotid atherosclerotic stenosis is to measure the degree of stenosis. Strong markers for plaque rupture lies in the plaque cont

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

Strålbehandling är en viktig behandling av cancer och det är avgörande att ge de föreskrivna stråldoserna exakt på rätt plats för att lyckas. Innan en patient behandlas verifieras strålbehandlingen genom kontrollmätningar. Dessa kontrollmätningar utförs med små detektorer som är placerade i ett fantom. Dessa mäter dosen endast i de punkter där de placeras. Stråldosen som ligger mellan dessa punkteBackground & Purpose: Radiation therapy is an essential treatment for cancer patients with the ultimate goal to deliver radiation doses to the tumour with precision while minimizing exposure to surrounding healthy tissues. Treatment verification is crucial to ensure the accuracy of radiation delivery, for instance by measuring the radiation dose distribution. Among various dosimetry techniques

Protection of humanitarian aid workers (HAWs) is a challenging task. There are various reports on the topic where much research seems to focus on traditional physical attacks and intentional violence against HAWs (security) rather than the accidental event risks (safety) or discussing it separately. These risks are usually defined by the organization’s security risk management holding the power in

The idea of orienting the design process towards the well-being of the patient is not something new in the world of architecture. That the form follows the function is usually but what must be taken into account is the dynamics of the process of understanding human needs. With each day that passes, complex changes of different kinds affect the human being and society as a whole in an unalterable t

Utforskning av flerkanalig intramuskulär elektromyografi (iEMG) för förbättrad protesstyrning Ingress: Med inspiration från hur hjärnan koordinerar muskler för att skapa rörelser, något som kallas muskelsynergier, utforskar detta examensarbete användningen av flerkanalig iEMG för att med större precision uppskatta isometriska krafter från handen Brödtext: Människans rörelser styrs av komplexa saThis Master's thesis in Biomedical Engineering investigates the performance and generalizability of linear regression models in context of prosthesis control for short residual limb amputees. This thesis uses intramuscular electromyography data, and a regression and emplys a regression technique called Elastic Net Regression - a technique that combines L1 and L2-regularization - to predict 1-D

The aim of this thesis is to study teachers’ perception of children’s ability to evacuate, thus learning about children’s evacuation behavior. Questions of interest are teachers’ perception of children’s ability to evacuate, their behavior, if there are any misconceptions in the teachers’ perception and how fire evacuation drills influence the teachers’ perceptions. This was done through a questio

Background: The Supreme Court’s Dobbs v. Jackson Women’s Health Organization ruling was monumental for sexual and reproductive health and rights in the United States. This shifted the legislative power over the right to an abortion from federal to state government. Missouri’s post- Roe legislation banned abortion statewide. Health care providers (HCPs) are facing unique facilitators and barriers t

Pneumonia is a common infectious disease of the lungs. When the lung tissue becomes inflamed, it can lead to symptoms such as cough, fever, and difficulty breathing. The most common cause of pneumonia is the bacterial species Streptococcus pneumoniae, also known as pneumococcus. This species is sometimes found in cultures from the nose or throat, without causing disease. If the immune system is we

The purpose of this paper has been to study whether or not the Swedish language has any significant impact on immigrant integration and their psychic well-being in Swedish society. By adhering to the theoretical framework of Diaz, Gordon, and Heckmann for integration, and Antonovsky’s theory of salutogenesis, we’ve established our results using qualitative semi-structured interviews to get our emp

Given the importance of copper prices to investors, governments, and policymakers, this paper investigates short-term price predictability using VAR and XGBoost models. All models are trained with historical data from November 2021 to December 2022 and using MSE, RMSE and MAE for evaluating the model performance. The results show that the XGBoost model outperforms VAR models, implying that machine

With Russia becoming increasingly hostile towards the West with the culmination of the full-scale invasion into Ukraine in February of 2022, the rhetoric of Putin has been linked to the philosophy of a geopolitically aggressive right-wing sociologist called Alexander Dugin. With several previous statements pertaining to the delegitimization of the sovereignty of Europe Dugin has previously argued

The banking and financial services industry is experiencing a significant transformation driven by factors such as regulatory changes, customer demands, and the growing focus on data. This evolution has given rise to the concept of open finance, an extension of open banking that encompasses various financial sectors. Open finance aims to promote data sharing and access across the industry, with th

Situated in the context of the global rise of the right and growing anti-feminist and anti-gender mobilization, this thesis explores the impacts of Jair Bolsonaro's right-wing populist government (2019-2022) on feminist activism in Brazil from an activist's perspective. It investigates the shifts and disruptions this government has entailed on three levels: in the realms of social public p

The primary aim of this study has been to examine to what extent people with addiction experience feelings of loss and sorrow as they go from being active in their abuse, to being an addict in recovery. The study is based on life stories generated from semi-structured, qualitative interviews, meaning the results are built on the voices of 6 people who are all recovering addicts. The complex emotio

According to the Swedish Care of Young Persons Act (LVU), rulings regarding compulsory care should be independent of aspects of gender, ethnicity, or social background. This paper aims to examine on what grounds youths are taken into compulsory care according to the prerequisite “other socially destructive behavior” stated in 3 § LVU. Meanwhile, how administrative courts apply the concept of the c

As the number of displaced people is increasing globally, host countries are experiencing difficulties in keeping up with the increasing demands of their growing population.
