INTRODUCTION: Intracranial haemorrhage (ICH) is the most serious complication in infants and children with severe congenital bleeding disorders causing substantial mortality and long-term neurological morbidity. The neonatal period carries the highest risk, particularly in severe haemophilia and rare factor deficiencies. We review the epidemiology, risk factors, prevention, recognition, management

This thesis investigates the long-run performance of IPOs in the U.S. market, a topic that remains timely given the historic issuance wave in 2020–2021 and the sharp monetary tightening that followed. Analysing 1,222 IPOs listed between 2015 and 2025, the study applies Buy-and-Hold Abnormal Returns (BHAR), Propensity Score Matching (PSM), and Fama-French calendar-time regressions to evaluate perfo

This study investigates the relationship between military expenditure, economic growth, and technological progress in 27 OECD countries over the period 1970–2019. While previous research on the economic consequences of military spending has produced mixed and often inconclusive results, this paper extends the literature by including total factor productivity (TFP) as a measure of long-term technol

This study investigated the presence of microplastics (MPs, >5 μm to <2 mm) in biofertilizers and estimated their mass input to Swedish agricultural soils. Collective samples from representative biogas facilities were analyzed using optical microscopy and optical photothermal infrared (O-PTIR) spectroscopy, with selected MPs examined by scanning electron microscopy (SEM). The highest MPs concentra

Groundwater stored in alluvial fan aquifers represents a key water resource in semi-arid mountainous regions, yet groundwater recharge mechanisms and flow dynamics remain poorly understood, particularly in data-scarce regions experiencing increasing water demand and anthropogenic pressure. This study investigates groundwater recharge processes and flow patterns in three adjacent watersheds of the

Railways play an important role in the energy transition by offering a low-carbon, energy-efficient means of transporting goods, people, and services. However, this role is increasingly at risk as extreme weather events associated with a changing climate grow in severity and frequency, compounded by uncertainties in future climate conditions.This thesis aims to advance the understanding of climate

T.M. Scanlon’s version of contractualism has emerged as one of the most well-developed challengers to consequentialism. According to one of contractualism’s most appealing features—the Individualist Restriction—the justifiability of our actions depends solely on the personal reasons of single individuals. While it allows contractualism to avoid many of consequentialism’s most implausible implicati

Denna avhandling undersöker styrningen av koldioxidavskiljning och -lagring (CCS) i den nuvarande fasen av policydriven implementering inom europeisk klimatpolitik. Min forskning placeras i mellan etablerad kritik av CCS och dess framväxande, centrala roll i bindande nettonollstrategier. Jag intar en kritiskt pragmatisk hållning som erkänner att CCS är en omtvistad teknik som innebär risker för inThis thesis examines the governance of Carbon Capture and Storage (CCS) technology in its current phase of policy-driven deployment within European climate policy. Positioned in the gap between established critique of CCS and its newly central role in binding net-zero strategies, my research adopts a critical-pragmatic stance to acknowledge that CCS is a contentious technology embodying risks of c

Kapitlet redogör för hur Universitetsbibliotekets samling av vardagstryck (tidigare Okatalogiserat tryck eller Småtrycket) kunde användas som källmaterial i prishistorisk forskning som bidrog till konstruktionen av Sveriges historiska nationalräkenskaper. I källmaterialet dök Emil Svensson i Lönneberga oväntat upp som en recensent av Öfverums slåttermaskin 1892 och han uppskattade särskilt maskine

Modern battery chargers require AC-DC converters with high input power quality, nearly unity power factor, and low current harmonics to meet grid standards such as IEC 61000-3-2. This paper proposes a two-stage charger topology: a front-end bridgeless interleaved boost PFC converter followed by a synchronous buck DC-DC stage. The interleaved boost stage reduces input current ripple and losses whil

BACKGROUND: There is limited information concerning the current practice of intraoperative mechanical ventilation in obese patients, and the optimal ventilator settings for these patients are debated. We investigated intraoperative ventilation parameters and their associations with the development of postoperative pulmonary complications (PPCs) in obese patients.METHODS: We performed a secondary a

The market for fully electrified vehicles is expanding fast. The number of sources and loads that are connected to the vehicles traction voltage systems (TVS) are increasing and thus also the ElectroMagnetic Compatibility (EMC) requirements on these sources and loads. These requirements should make sure that neither function nor lifetime of any source or load is severely affected by another. The C

Objective This study aims to investigate whether oral fluoroquinolone use is associated with an increased risk of aortic and mitral valve regurgitation. Design A nationwide cohort study based on linked healthcare register data encompassing patient characteristics, prescription data and cases of aortic and mitral valve regurgitation. Setting Sweden, 2006–2018. Participants Study participants were a
