Energilösningen för Framtiden: Vattenpumplagring & Vindkraft Genom åren har användningen av fossila bränslen minskat, samtidigt som vi sett en ökning av förnybara energikällor som vindoch solkraft. Sverige står dock inför en utmaning: vindens oförutsägbara natur skapar problem för elnätets stabilitet. Denna rapport utforskar möjligheterna kring el-lagring genom vattenpumplagring kopplat till The introduction of the Renewable Energy Directive 2009, increased the renewable energy sources (RES) in the European Union (EU) and especially Sweden. Given the uncontrollable nature of weather patterns, energy generation is likely to become more volatile, thereby elevating the risk of curtailment and negative energy prices. The electricity demand in Sweden is also poised to rise sharply in the u

This thesis has investigated the municipal urban project Warszawska Dzielnica Społeczna (WDS) in the district of Wola, Warsaw, Poland. WDS was a city initiated urban project presented in 2019. The project has not been realized. When speaking to city officials, it remained unclear as to why. Therefore, it was found interesting to investigate why the organization that initiated the project, did not

BACKGROUND: Aortic pulse wave velocity (PWV) is an indicator of vascular aging and has proven to be effective in adult cardiovascular risk assessment. To use it in young people to identify those who may be at increased cardiovascular disease risk, reference values need to be determined. The Youth Vascular Consortium is a large, international database which was established to investigate vascular a

Since the conceptualization of early vascular aging (EVA) in 2008, significant efforts have been made to develop and improve its assessment. Initially lead by the investigation of arterial stiffness through pulse wave velocity (PWV), several additional vascular aging biomarkers have gained prominence in recent years. Despite expanding literature addressing methodological concerns associated with t

Hybrid zones present a unique framework to study the genetic basis of reproductive isolation and speciation. The European fire-bellied toad (Bombina bombina) and yellow-bellied toad (B. variegata) hybridize in a zone across several thousand kilometres in Central Europe. The Bombina system has been examined for more than a century and its scientific legacy comprises the development of the ultilocus

This thesis explores advancements in Automatic Speaker Verification (ASV) by examining the impact of multiple speaker enrollments and introducing Adaptive Neural Probabilistic Linear Discriminant Analysis (Adaptive NPLDA). Modern ASV combines front-end feature extraction, using state-of-the-art methods based on Deep Neural Networks (DNNs), such as the ReDimNet architectures, with back-end modeling

BACKGROUND: Numerous studies report that education and exercise interventions can shift people's willingness to undergo joint replacement surgery for osteoarthritis. We aimed to investigate whether becoming unwilling to undergo surgery following an education and exercise intervention for hip and knee osteoarthritis is associated with lower probability of receiving actual surgery.METHODS AND FINDIN

The House Sparrow (Passer domesticus) began to colonize the Faroe Islands in the mid-1940s and occurs in most built-up areas. Breeding is confined to the discrete human habitations (settlements) that form a pattern of patches (”habitat-islands”). In 2002 all settlements were surveyed and the number of pairs of sparrows (total number ca. 2,700 pairs) and amount of vegetation (”green space”) were es

Background: Botulinum toxin A (BTX-A) has been used to reduce spasticity in children with cerebral palsy (CP) for decades. The purpose of this study was to analyze to what extent BTX-A treatment was used to treat spasticity in a total population of children with CP. We investigated 1) the use of BTX-A in relation to age, sex, and Gross Motor Function Classification System (GMFCS) level, 2) the mos

Glucagon is the main counterregulatory hormone in the body. Still, the mechanism involved in the regulation of glucagon secretion from pancreatic alpha cells remains elusive. Dysregulated glucagon secretion is common in patients with Cystic Fibrosis (CF) that develop CF related diabetes (CFRD). CF is caused by a mutation in the Cl- channel Cystic fibrosis transmembrane conductance regulator (CFTR)

Objectives:We aimed to investigate possible associations between birth weight and adult life carotid-femoral pulse wave velocity (cfPWV) and augmentation pressure index (AIx).Design and method:This study included 1598 participants, that is, 340 elderly individuals from the Malmö Birth Data Cohort (MBDC) and 1258 young-middle aged individuals from the Malmö Offspring Study (MOS) with full data on b

A software breast phantom, based upon a breast tissue model derived from physical properties of breast anatomy, has been developed for mammography simulation. Synthetic mammograms, obtained by applying a breast compression model and an x-ray acquisition model to the software breast phantom, were compared by quantitative and qualitative means with real mammograms at different scales. Good agreement
