Critical recurrence in real quadratic and rational dynamics

In this thesis we study the dynamics of real quadratic functions on the interval, and rational functions on the Riemann sphere. The problems we are considering are concerned with the recurrent nature of the critical orbit(s). In Paper I we investigate the real quadratic family and prove a theorem regarding the rate of recurrence of the critical point to itself, extending a previous result by Avila

Hydroxyl radical dynamics in a gliding arc discharge using high-speed PLIF imaging

Plasma discharges can be transient and randomly distributed where a few investigations have been carried out using laser-induced fluorescence to capture snapshots of plasma-produced radicals in the near vicinity of the discharge. Radical distribution dynamics, however, are challenging to study in situ with high spatial and temporal resolution to fully capture the interactions between the discharge

The measured distance between tumor cells and the peritoneal surface predicts the risk of peritoneal metastases and offers an objective means to differentiate between pT3 and pT4a colon cancer

Substantial variability exists in what pathologists consider as pT4a in colorectal cancer when tumor cells are within 1 mm of the free peritoneal surface. This study aimed to determine if the measured sub-millimeter distance between tumor cells and the free peritoneal surface would offer an objective means of stratifying patients according to the risk of developing peritoneal metastases. Histologi

Plasma proteome profiling of healthy individuals across the life span in a Sicilian cohort with long-lived individuals

The study of healthy human aging is important for shedding light on the molecular mechanisms behind aging to promote well-being and to possibly predict and/or avoid the development of age-related disorders such as atherosclerosis and diabetes. Herein, we have employed an untargeted mass spectrometry-based approach to study age-related protein changes in a healthy Sicilian plasma cohort including l

Uptake of cervical cancer screening and its predictors among women of reproductive age in Gomma district, South West Ethiopia : a community-based cross-sectional study

Background: Cervical cancer is a public health challenge despite the available free screening service in Ethiopia. Early screening for cervical cancer significantly improves the chances of successful treatment of pre-cancers and cancers among women of reproductive age. Therefore, this study aimed to assess the uptake of screening and identify the factors among women of reproductive age. Methods: A

Kynurenine metabolites predict survival in pulmonary arterial hypertension : A role for IL-6/IL-6Rα

Activation of the kynurenine pathway (KP) has been reported in patients with pulmonary arterial hypertension (PAH) undergoing PAH therapy. We aimed to determine KP-metabolism in treatment-naïve PAH patients, investigate its prognostic values, evaluate the effect of PAH therapy on KP-metabolites and identify cytokines responsible for altered KP-metabolism. KP-metabolite levels were determined in pl

Accelerating target deconvolution for therapeutic antibody candidates using highly parallelized genome editing

Therapeutic antibodies are transforming the treatment of cancer and autoimmune diseases. Today, a key challenge is finding antibodies against new targets. Phenotypic discovery promises to achieve this by enabling discovery of antibodies with therapeutic potential without specifying the molecular target a priori. Yet, deconvoluting the targets of phenotypically discovered antibodies remains a bottl

Meaning-making in a context of climate change : Supporting agency and political engagement

Responding effectively to climate change requires an understanding of what shapes people’s individual and collective sense of agency and responsibility towards the future. It also requires transforming this understanding into political engagement to support systems change. Based on a national representative survey in Sweden (N = 1,237), this research uses the novel SenseMaker methodology to look i

Moisture Levels in Historic Timber Walls Insulated with Hemp-Lime

The European Union has a low-carbon roadmap that aims at reducing greenhouse gas emissions toprevent further climate change and achieve climate-neutrality by 2050. Many of the historical buildings that wehave today will still be around in 2050. Hence, there is a need to improve their energy performance. A way to dothis is to use hemp-lime as a material for renovation. Hemp shiv, the woody core par

Structures of Atm1 provide insight into [2Fe-2S] cluster export from mitochondria

In eukaryotes, iron-sulfur clusters are essential cofactors for numerous physiological processes, but these clusters are primarily biosynthesized in mitochondria. Previous studies suggest mitochondrial ABCB7-type exporters are involved in maturation of cytosolic iron-sulfur proteins. However, the molecular mechanism for how the ABCB7-type exporters participate in this process remains elusive. Here

Therapist-guided internet-based psychodynamic therapy versus cognitive behavioural therapy for adolescent depression in Sweden : a randomised, clinical, non-inferiority trial

Background: Adolescent major depressive disorder (MDD) is highly prevalent and associated with lifelong adversity. Evidence-based treatments exist, but accessible treatment alternatives are needed. We aimed to compare internet-based psychodynamic therapy (IPDT) with an established evidence-based treatment (internet-based cognitive behavioural therapy [ICBT]) for the treatment of adolescents with d

Recommendations for the execution and reporting of skin ultrasound in systemic sclerosis : an international collaboration under the WSF skin ultrasound group

Objective Ultrasound is a promising tool to foster much-needed improvement of skin assessment in systemic sclerosis (SSc). Our aim was to develop evidence and expert opinion-based recommendations to promote the standardisation and harmonisation of technical execution and reporting of skin ultrasound studies in SSc. Methods A multidisciplinary task force of 16 members from five European countries a

Media Engagement

Written with media students in mind, this accessible book provides both students and researchers with a new perspective on how to research engagement, not as a metric but as a marker of power relations.This book navigates the reader through a tighter analytical notion of engagement within an understanding of media, culture and democracy. Dahlgren and Hill offer a new definition of engagement as an

Futures of Fixing : Exploring the life of product users in circular economy repair society scenarios

A Circular Economy (CE) constitutes one pathway towards realising sustainable productionand consumption. Here, the repair of broken products (compared to replacement) consti-tutes an important strategy to keep products in the economy for longer, thereby reducingwaste, as well as the need to extract resources and emit pollution in the manufacture of areplacement product. In today’s world, repair do
