The synthesis of phospholipids with defined fatty acid and polar head composition catalysed by lipases and phospholipases was investigated. Lipases from Rhizopus arrhizus and Candida antarctica were used for the direct acylation of DL-a-glycerophosphate and L-a-glycerophosphatidylcholine, with different fatty acids. Esterification reactions can be carried out in systems with low wate
AIMS: Although the perpetuation of several supraventricular arrhythmias is critically dependent upon intra-atrial conduction, the literature lacks detailed information on normal values of conduction velocity and degree of anisotropy. In order to explore these factors further, we have measured conduction velocities at the right atrial free wall during sinus rhythm and during atrial pacing in four d
Popular Abstract in Swedish Kroppens blodglukoskoncentration regleras av celler i de Langerhanska öarna i bukspottkörteln. β (beta)-celler frisätter insulin då sockerhalten i blodet ökar, tex efter en måltid. Insulin verkar via speciella membranbundna proteiner (receptorer) på celler i muskel, hjärta och fettväv och påverkar dessa att ta upp glukos från blodet. När blodsockerhalten sjunker, t.ex. We have investigated the in vitro effects of long-chain free fatty acids (FFAs) on mouse pancreatic α- and β-cells by a combination of electrophysiological recordings, intracellular Ca2+ ([Ca2+]i) microfluorimetry and hormone release measurements. Acute addition of the saturated FFA palmitate to intact islets doubled insulin as well as glucagon secretion in the presence of 1 or 15 mM glucose and t
Emulsification is an important unit operation used in the pharmaceutical, food, and cosmetic industry. Membrane emulsification is a relatively new membrane technology which allows the production of emulsion droplets under controlled conditions with a narrow droplet size distribution. The continuous phase flows tangentially to the membrane surface and sweeps away dispersed phase droplets forming fr
L-type voltage-gated Ca2+ channels are expressed in the plasma membrane of muscles, neurons and endocrine cells where they serve as conductors of signals regulating cellular responses to changes in environment. Malfunctions of channels, as well as deregulations of their activity underlie numerous disorders and diseases commonly called channelopathies. In β-cells Ca2+ channels are central players f
Den senaste tidens teknikutveckling har gjort det möjligt för personer att streama film och serier på begäran. Flera tjänsteföretag såsom Netflix, HBO Nordic och Viaplay erbjuder sina tjänster mot en månatlig avgift. Däremot är tjänsterna sällan tillgängliga när en abonnent beger sig till en annan medlemsstat inom EU. Det är också sällan möjligt för en konsument att se en film eller serie som ett
The product price given when producing offshore is not the entire truth and more companies decide to move their offshore production nearshore (Stentoft et. al, 2016). To measure the actual cost of producing many more parameters than visible costs needs to be taken account for. There are advantages as well as risks with outsourcing and costs can increase with distance such as quality issues, freigh

BackgroundThe use of stereotactic body radiotherapy (SBRT) to definitively treat oligometastases in prostate cancer has drawn large clinical and research interests within radiation oncology. However, the evidence is considered in its early stages and there is currently no systematic review of randomized controlled trials (RCTs) in this field. We aimed to evaluate the efficacy and safety of SBRT as
Populärvetenskaplig sammanfattningIntroduktionI dagens digitala era har sociala medier och internet blivit centrala plattformar för nyhetsförmedling och offentlig debatt. Denna utveckling har främjat snabbare informationsspridning och ökat engagemang i samhällsfrågor. Samtidigt har det också medfört en ökning av negativa påtryckningar i form av trakasserier, hat och allmänt ogillande, särskilt rikIntegrating socio-legal analysis and working life science, this compilation thesis aims to enhance the understanding of how the evolving digital landscape—particularly the rise of online harassment—influences journalism and its potential to foster healthy public discourse. Additionally, the thesis seeks to advance the field of socio-legal studies by examining the interplay between digital transfor
Abstract Several international instruments including CEDAW have recognized every human being to be free from any form of violence including being free from inhuman and degrading treatment. Equality of men and women is also recognized starting from the establishment of UN in 1945 under its charter. UDHR, ICCPR and ICSECR are the major international human right instruments which recognized the appl
Den som köper en bok eller en cd-skiva har rätt att sälja vidare den köpta kopian – rättsligt benämnt konsumtion av spridningsrätten. I takt med den digitala utvecklingen köper dock allt fler konsumenter upphovsrättsliga verk på internet. I en dom från 2012 fastslog EU-domstolen att konsumtion av spridningsrätten vad gäller datorprogram inte var begränsad till fysiska kopior. Domen framkallade en Anyone who buys a book or a CD is entitled to resell the purchased copy. This rule is often known as the ‘exhaustion of the distribution right’. The digital revolution has, however, resulted in an increasing number of consumers buying copyright works online. In a 2012 judgment, the ECJ ruled that the application of the rule was not limited to physical copies of software. The judgment triggered a d
Med en ökad globalisering i världen sker fler gränsöverskridande situationer mellan två länder som på ett eller annat sätt påverkar både företag och de enskilda. Denna uppsats fokuserar på vad som, skattemässigt, kan ske för den enskilda i en gränsöverskridande situation. Vid en sådan situation finns det risk för att den skattskyldige utsätts för en dubbelbeskattning då både hemviststaten och källWith increased globalization in the world, there are more cross-border situations between two countries that in one way or another affect both companies and individuals. This essay focuses on what, for tax purposes, can happen to the individual in a cross-border situation. In such a situation, there is a risk that the taxpayer will be subject to double taxation as both the state of residence and t
Acoustophoresis, i.e., the contactless manipulation of small cells or particles via acoustic waves is a gentle and label-free method that can, amongst others, be used to isolate rare cells such as circulating tumor cells from blood. To isolate enough cells, a large amount of sample needs to be processed in a reasonable amount of time. In a clinical setting, usually around 10 mL of blood can be col
In the future atmospheric CO2 concentrations might exceed 550 ppm according to the RCP8.5 scenario by mid-century from our current 410 ppm, while our world population is projected to surpass the 9.7 billion threshold within the same time span. This challenge leads to the raising of questions addressing future food security. Elevated CO2 has been shown to not only increase photosynthetic rates in
Popularvetenskaplig sammanfattning: Storkprojektet i Skåne – nutid och framtid Den vita storken (Ciconia ciconia) har varit utdöd i Sverige sedan 1954. Orsaken till storkens försvinnande tros ha varit en kombination av utdikningar av våtmarker, ökad dödlighet samt en generellt nedåtgående trend hos storkpopulationerna i övriga Europa. Sedan 1989 pågår ett återintroduceringsförsök i Skåne. Genom Abstract: In 1954 the last breeding attempt by the White Stork (Ciconia ciconia) in Sweden failed and the species was declared extinct from the Swedish fauna. Reasons for the extinction are thought to be a combination of issues such as habitat conversion, increased mortality and an overall decline of the European White Stork populations. Since 1989 an ongoing reintroduc-tion programme for the Whi
The thesis aims to explore and understand gender inequality that exists in the global labour market in general and for the Bangladeshi female immigrants in particular. It emphasises feminization of employment in relation to state-market-family relations. The thesis also discusses the ways and to what extent Bangladeshi female immigrant’s roles are sources of entitlement to the provision of UK’s la
In this thesis we study efficient solvers for space-time discontinuous Galerkin spectral element methods (DG-SEM). These discretizations result in fully implicit schemes of variable order in both spatial and temporal directions. The popularity of space-time DG methods has increased in recent years and entropy stable space-time DG-SEM have been constructed for conservation laws, making them interes
Existing oculoplastic reconstructive surgical techniques are based on empirical knowledge and were established long before perfusion monitoring was possible. It is believed that an avascular graft should always be placed on a vascular bed or flap and also that the viable length of a flap depends on the width of its pedicle. The actual role of the length, width and thickness of a random flap in its
A central function of human cognition is the ability to perceive, understand, and remember life experiences as meaningful sequences of discrete events. This process, known as event segmentation, allows individuals to spontaneously construct and update event models and has been shown to engage a distributed network of brain regions that transiently increase in activity at event boundaries (e.g., Za
