A method is presented that combines advanced experimental and numerical techniques in the determination of constitutive parameters. The general principle is that a specimen, producing a non-homogeneous stress state, is deformed rapidly. Load and deformation is recorded during the deformation and the event is also simulated using FEM. For the numerical calculation a set of constitutive parameters i
There is a lack of clinical protocols for re-irradiation in paediatric central nervous system (CNS) tumours. To fill this void, the Swedish Workgroup of Paediatric Radiotherapy (SBRTG) compiled national guidelines on re-irradiation in paediatric CNS tumours (diffuse intrinsic pontine glioma, ependymoma, germinoma and medulloblastoma). These have been in clinical practice since 2019 in all paediatr
Perception is not a passive process but the result of an interaction between an organism and the environment. This is especially clear in haptic perception that depends entirely on tactile exploration of an object. We investigate this idea in a system-level brain model of somatosensory and motor cortex and show how it can use signals from a humanoid robot to categorize different object. The model
AbstractThe overall aim of this thesis was to explore women´s experiences of the second stage of labour, midwifery practices and the use of interventions.Methods: Study I is a retrospective cohort study where 764 medical records from 2017 were reviewed. Women in Robson group 1 were included. Descriptive and analytic statistics were used to describe the use of oxytocin and to compare mode of birth
Background: The neotropical anopheline mosquito Anopheles darlingi is a major malaria vector in the Americas. Studies on mosquito-associated microbiota have shown that symbiotic bacteria play a major role in host biology. Mosquitoes acquire and transmit microorganisms over their life cycle. Specifically, the microbiota of immature forms is largely acquired from their aquatic environment. Therefore
BACKGROUND: Stereotypes may prevail, but little is known about the influence that the sex of an orthopaedic surgeon may have on outcomes. In a recently published study, there were no differences in the rate of adverse events following total hip arthroplasties (THAs) performed by female or male orthopaedic surgeons. The objective of the present study was to investigate whether there was any differe
Background Although physiology-based assessment of coronary artery stenosis using instantaneous wave-free ratio (iFR) and fractional flow reserve (FFR) are established methods of guiding coronary revascularization, its clinical outcome in long-term deferral needs further evaluation, especially with acute coronary syndrome as a clinical presentation. The aim was to evaluate the long-term clinical o
In some nuclear power plants, the containment liners are embedded in concrete. The purpose of the containment liner is to minimize the risk of radioactive leakage by granting a leak-tight containment building. In the presence of flaws in the surrounding concrete, such as voids, or foreign objects embedded in the concrete, there is a risk that the liner plate might corrode. This could degrade the l
Here we characterize a new animal model that spontaneously develops chronic inflammation and fibrosis in multiple organs, the non-obese diabetic inflammation and fibrosis (N-IF) mouse. In the liver, the N-IF mouse displays inflammation and fibrosis particularly evident around portal tracts and central veins and accompanied with evidence of abnormal intrahepatic bile ducts. The extensive cellular i
This study investigated the characteristics of each of the specific DSM- III-R (American Psychiatric Association, 1987) anxiety disorders in a clinic sample of 188 anxiety disordered children. Characteristics examined included sociodemographic variables (age-at-intake, gender, and race of the child, and family marital and socioeconomic status) and clinical variables (disorder age-at-onset and seve
Only in Sweden, single-family houses account for approximately 30% of energy use in all buildings and a large part uses only electricity for heating. The potential for improvements on energy efficiency in these houses is large. This study theoretically investigates retrofitting of electrically heated Swedish single-family houses by using an air-source heat pump for both space heating and domestic
Type 1 conventional dendritic cells (cDC1s) are rare immune cells critical for the induction of antigen-specific cytotoxic CD8+ T cells, although the genetic program driving human cDC1 specification remains largely unexplored. We previously identified PU.1, IRF8, and BATF3 transcription factors as sufficient to induce cDC1 fate in mouse fibroblasts, but reprogramming of human somatic cells was lim
BackgroundThe geometrical relationship between atrial and ventricular short‐axis cross‐sectional area determines the hydraulic forces acting on intracardiac blood. This is important for diastolic filling. In patients undergoing heart transplantation (HTx), the left atrium is often enlarged as a result of the standard surgical technique. We hypothesized that diastolic filling in HTx patients is aff
The control of the Touch Hand: a low-cost electrically powered prosthetic hand is explored in this paper. A novel Haptic User Interface is proposed and tested as a supplement for amputee-prosthetic EMG control. The performance of the prosthetic hand is tested through gripping tests. The hand is capable of performing a lateral grip of 3.7 N, a power grip of 19.5 N and to passively hold a weight of
