Aim: Grass-yellow butterflies (Eurema) are a group of pantropical Pieridae distributed throughout Asia, Australasia, Africa and the New World. However, little is known about their diversification, including the biogeographic mechanism(s) explaining their circumglobal distribution. We present the first densely sampled, time-calibrated phylogeny and biogeographic reconstruction of grass-yellows to c
Sustainable energy storage and conversion explores innovative methods to efficiently store and transform energy from various renewable sources. It focuses on technologies like advanced batteries, hydrogen production, fuel cells, and thermochemical systems as well as safety aspects of battery storage systems. Research aims to enhance energy density, reduce costs, and improve scalability, enabling r

Despite rapid development, modern graphics hardware is still much too slow to render photo-realistic images in real time, and it will most likely remain so if we rely only on yearly growth in hardware performance. Therefore, better algorithms are constantly needed in order to advance the field. In the first part of this thesis, we present new algorithms for hardware rasterization. We investigate
A novel strategy for efficient growth of nitrogen-doped graphene (N-graphene) on a large scale from s-triazine molecules is presented. The growth process has been unveiled in situ using time-dependent photoemission. It has been established that a postannealing of N-graphene after gold intercalation causes a conversion of the N environment from pyridinic to graphitic, allowing to obtain more than 8
With the advent of cheap sensors and computing capabilities as well as better algorithms it is now possible to do structure from motion using crowd sourced data. Individual estimates of a map can be obtained using structure from motion (SfM) or simultaneous localization and mapping (SLAM) using e.g. images, sound or radio. However the problem of map merging as used for collaborative SLAM needs fur
This Thesis will limit itself to exercising architectural interventions based on a set of identified locations with the aim of creating a framework for new housing units. The architectural intervention will form round these sites, social groups and economical building methods with ambition of being integrated in the urban framework limiting need to travel and utilising existing infrastructure. Mat
This thesis delves into Louis Spohr and his First Concerto for Clarinet and Orchestra, Op. 26, starting with an overview of the composer's life and his work. The analysis will provide a better understanding of the meaning and characteristics of this composer's writing during his musical career. The thesis also explores the performance of his concerto that is closer to the composer’s origin
Bacteria can cause life-threatening infections, such as pneumonia, meningitis, or sepsis. Antibiotic therapy is a mainstay of treatment, although antimicrobial resistance has drastically increased over the years. Unfortunately, safe and effective vaccines against most pathogens have not yet been approved, and thus developing alternative treatments is important. We analyzed the efficiency of factor
The spontaneous open-field behavioural effects of 10 days of chronic treatment with two clinical doses (10 and 20 mg/kg daily) and one high/toxic dose (100 mg/kg daily) of the selective serotonin reuptake inhibitor citalopram (delivered subcutaneously by implanted osmotic pumps) were examined in rats. Central and peripheral arena locomotor and rearing activities were recorded simultaneously, and t
Stroke causes direct structural damage to local brain networks and indirect functional damage to distant brain regions. Neuroplasticity after stroke involves molecular changes within perilesional tissue that can be influenced by regions functionally connected to the site of injury. Spontaneous functional recovery can be enhanced by rehabilitative strategies, which provides experience-driven cell s
Syftet med uppsatsen var att studera hur börsnoterade fotbollsklubbars aktier reagerar vid spelartransaktioner och vid kvalifikationsmomentet till Champions League. För att genomföra denna undersökning använde vi oss av en kvantitaitv metod, där vi studerade spelartransaktioner och kvalifikationsmomentet till Champions League enligt Event study teknik. Empirins utgörs av börskurser från de fyra kl
Purpose: This paper aims to review total quality management (TQM) literature in the past three decades to identify the quality related key terms, to analyse their linkage among the identified key terms and their developmental trends. Design/methodology/approach: Bibliometric and statistical methods are used to analyse article titles published in the Total Quality and Business Excellence journal du
Homozygous C2 deficiency (C2D) is the most common deficiency of the classical complement pathway in Western countries. It is mostly found in patients with autoimmune disease or susceptibility to bacterial infections and in healthy persons. We wished to assess to what extent other immunological factors might explain differences of susceptibility to infections in C2D. For this reason, 44 Swedish pat
