Most migratory bird species divide their migration in stages of flight and stopovers. They use these stopovers to refuel the energy reserves needed to face their long migration journeys. These stopovers are an important element to determine the overall migration speed. Time spent on migration and arrival date to the wintering grounds have been demonstrated to have a large effects the following bre
Kolloider är partiklar i storleksordningen nm till μm. De är viktiga i biologiska system, där exempelvis proteiner är en typ av kolloid. Att studera kolloider ger oss därför insikt i hur till exempel proteiner byggs upp och interagerar. I detta fall försökte vi tillverka kolloidala molekyler, alltså kolloider som interagerar med varandra genom ett specifikt antal bindningar i väl definierade positThe ability of thermoresponsive, amine-functionalized microgel particles to take part in microgelmicrogel inter-cross-linking has previously been reported in the literature, in connection to applications such as for example the formation of stimuli-responsive colloidal gels and colloidosomes [1]. This thesis deals with the synthesis of such thermoresponsive, cross-linkable microgels and their subs
The purpose of this essay is to examine how two nonfiction books for children in the category sexual education from Sweden portrays gender and sexuality. Norman Fairclough’s critical discourse analysis is the method of choice, where the nonfiction books are seen as part of a discourse in which language is not neutral. The analysis is based on Judith Butler’s theories on the heterosexual matrix and
TMP, kort för Trimetylolpropan, är en kemisk komponent som används som byggsten för alkydproduktion inom färgindustri samt som komponent i syntetiska smörjmedel. Perstorp har under drygt 50 år producerat TMP för vidare försäljning till andra kemiska industrier. Under denna period har produktionskapaciteten ökat många gånger om. Denna produktivitetsökning har kommit som följd av ett ”trial and erroThe production of TMP (Trimethylolpropane) is important for many applications, and is used as alkyds in paint and lubricants among others. The reactions producing TMP consist of two major reaction chains, Aldol condensation and Cannizzaro reaction. To get a deeper understanding and improve the running conditions the kinetic expressions for the reactions were examined. The aim of this paper was to
Korrosion (rost) är ett stort forskningsområde som hunnit komma långt, men fortfarande finns det mycket kvar att lära. Detta kan man se enbart genom att reflektera över de nästan 100 miljarder kronor som korrosionsskador kostar samhället i Sverige årligen. Rostfritt stål har ett vilseledande namn då det faktiskt rostar i vissa miljöer. I detta projekt har korrosion av rostfritt stål undersökts i o
ABSTRACT The aim of this exploratory study was to examine what motivates social workers in the drug abuse field to remain in their jobs for longer than five years. Data was collected via semi-structured face-to-face interviews with five social workers in a municipal social services administration in south-western province of Scania. The analysis empolyed qualitative approach using Herzbergs two-
The proliferation of plastic waste poses a significant contemporary challenge, driven by global population growth and the subsequent surge in plastic consumption. PE alone accounts for roughly 50-60% of the plastic waste stream. Its formidable resistance to enzymatic degradation, owing to its stable carbon-carbon (C-C) backbone and carbon-hydrogen (C-H) bonds, further exacerbates the issue. This s
This paper focuses on constructing models that predict a Value at Risk (VaR) estimation for financial portfolios using hierarchical clustering and copulas. Traditional VaR models often assume linear dependencies and normal distributions, which can be poor assumptions for financial data - especially during extreme market events. This paper introduces a non-linear modeling approach using copulas to
I samband med påföljdsreformen år 1989 infördes preciserade regler för påföljdsval och straffmätning i det svenska straffrättssystemet, med syftet att öka förutsägbarheten och möjliggöra en enhetlig rättstillämpning. Bland annat infördes billighetsskälen, ett antal skäl hänförliga gärningspersonen, dennes agerande eller sådant som inträffat efter begånget brott. I det fall omständigheten är av särIn connection with the Swedish penal reform of 1989, specific rules for sentencing and penalty assessment were introduced into the Swedish criminal justice system, with the aim of increasing predictability and enabling uniform application of the law. The grounds for equity were established, consisting of various factors related to the offender, his or her actions, or events occurred after the crim
Editionsinstitutet och den processuella editionsplikten möjliggör för en part att med domstolens hjälp, under vissa förutsättningar, avtvinga motpart eller tredje man skriftliga handlingar som kan tänkas äga betydelse som bevis i en pågående tvist. En hel del har skrivits om editionsinstitutet och den processuella editionsplikten. Trots detta är rättsläget i många avseende fortfarande oklart. HögThe procedural duty of disclosure enables a party, with the assistance of the court and under certain conditions, to compel the opposing party or a third party to produce written documents that may be deemed significant as evidence in an ongoing trial. Much has been written about the procedural duty of disclosure. Nevertheless, the legal landscape remains unclear in many respects. In recent years

Riktade nyemissioner är vanligt förekommande på den svenska aktiemark-naden. De används bland annat som ett alternativ för bolag att snabbt och kostnadseffektivt ta in kapital och att tillföra bolagen externa investerare. Be-fintliga aktieägare har dock enligt huvudregeln företrädesrätt att teckna nyemit-terade aktier i bolaget, och en riktad nyemission innebär en avvikelse från denna huvudregel. Directed share issues are common in the Swedish stock market. They are used, among other things, as an alternative for companies to raise capital quickly and cost-effectively and to attract external investors. However, exist-ing shareholders generally have preferential rights to subscribe to newly is-sued shares in the company, and a targeted share issue deviates from this gen-eral rule. Therefore
This thesis explores the classification of savannah trees using EnMAP hyperspectral and Sentinel-2 multispectral satellite data using a Random Forest classifier. The study aimed to assess if the increase in spectral information from the hyperspectral data gives an increase in classification performance, to find the advantages and limitations to hyperspectral data compared to multispectral data and
Two-particle angular correlations between unidentified charged trigger and associated particles are measured by the ALICE detector in p-Pb collisions at a nucleon-nucleon centre-of-mass energy of 5.02 TeV. The transverse-momentum range 0.7 < p(T),(assoc) < p(T),(trig) < 5.0 GeV/c is examined, to include correlations induced by jets originating from low momentum-transfer scatterings (minijets). The
Background: Lumbar spine radiography has limited diagnostic value but low radiation dose compared with computed tomography (CT). The average effective radiation dose from lumbar spine radiography is about 1.1 mSv. Low-dose lumbar spine CT may be an alternative to increase the diagnostic value at low radiation dose, around 1 mSv. Purpose: To determine the optimal settings for low-dose lumbar spine
Objective. Overactive bladder (OAB) is a chronic condition that has a profound impact on health-related quality of life (HRQoL). This study measured changes in bother of OAB symptoms and self-perceived HRQoL over 6 months in patients treated with extended-release (ER) tolterodine in a naturalistic setting. Material and methods. This was a prospective, single-cohort observational study of patients
Changing Landscapes and Persistent Places is a study of the cultural landscape on the Bjäre peninsula in northwest Skåne. The many Bronze Age remains that give the landscape its distinctive character are the starting point for an attempt to increase our understanding of the historical depth of today’s landscape. The two perspectives of “landscape” and “places” carry the discussion forward, almost
Variable temperature photoemission studies in the literature have revealed the presence of a surface state above the Fermi level on clean Ge(001). We present photoemission and low energy electron diffraction results from Ge(001) obtained between 185 and 760 K. Our measurements show a peak above the Fermi level with a maximum intensity at a sample temperature of around 625 K. At higher temperatures
