Proteiner är stora biomolekyler som finns i alla levande organismer. De är uppbyggda av ett antal byggstenar, så kallade aminosyror med varierande egenskaper, och de utför många uppgifter som är essentiella för att liv skall kunna finnas. Hur proteiner interagerar med varandra och sin omgivning styr deras beteende vilket i sin tur är relaterat till deras funktion. Att förstå dessa interaktioner ärIn this work, lactoferrin was studied as a function of pH, starting at a low pH of 5.5 with 5 mM salt, in terms of interactions and dynamics with small angle X-ray scattering (SAXS), static and dynamic light scattering (SLS and DLS). Under these conditions lactoferrin was expected and found to have a strong electrostatic repulsion and behaved similar to an isotropic colloid. The glass transition w

Aim: The aim of this thesis is to get a deeper understanding of cultural integration in the pre-stage of a merger process and by doing so also contribute to an understanding of merger outcomes. Research Question: How is cultural integration managed in the pre-merger stage and how is this perceived by employees? Methodology: Through an interpretative epistemological approach we developed a quali

Har du tänkt på att du behöver kissa oftare än vanligt när du har druckit öl? Eller när du druckit te eller kaffe? Detta beror på ett hormon som heter vasopressin och som produceras i hypofysen. Vassopressin är en slags signal till njurarna att återvinna mer vatten från urinen. Koffein och alkohol påverkar hypofysen så att den producerar mindre vasopressin vilket gör så att mer vatten hamnar i uriAquaporin 2 (AQP2) acts as a water channel in the apical membrane of principal renal cells in the collecting ducts of the kidney. Upregulation is controlled by stimulation of these cells with vasopressin. Downregulation of the presence of AQP2 in the membrane occurs through ubiquitination and then sorting of the protein via the ESCRT-I, -II and –III complexes into the Multivesicular bodies (MVBs).

The Ease of Doing Business index, published by the World Bank, ranks countries by how easy it is to do business in them, with the goal of encouraging reforms favoring firms and economic prosperity. However, it is not guaranteed that the index is properly constructed to measure what it aims to measure, and the placement of certain countries on the index, as well as the results from a number of prev

The General Data Protection Regulation are coming as a response to the outdated Directive from 1995. With this, a lot tougher pressures are put on organisations regarding the demand for compliance, which is mainly done through higher penalties, giving organisations an in-citement to oblige. Seen from the perspective of information systems, organisations have to implement the requirements of the re

Syftet med denna uppsats är att ge en överblick över det nya, men snabbt växande, konceptet crowdsourcing. Konceptet kan enkelt beskrivas som en åtgärd att ta en uppgift som vanligtvis utförs av en utsedd arbetspresterande part (vanligtvis en anställd) och outsourca denna till en odefinerad, anonym och generellt stort grupp av människor i form av en ”öppen inbjudan”. Marknaden har under det senastThe purpose of this thesis is to provide an overview of the new, but rapidly growing, concept of crowdsourcing. The basis of the concept can be described as the act of taking a job traditionally performed by a designated agent (usually an employee) and outsourcing it to an undefined, generally large group of people in the form of an open call. In the last couple of decades, the market has exploded

This thesis seeks to answer what causes some governments to restrict foreign funding to domestic civil society organizations while others do not. These repressive measures have increased significantly in all regions of the globe recently and existing research has yet to provide an encompassing explanation for the trend. Considering that neither foreign funding or government repression are exactly

Nukleosynthes i ackretionsskrivor kring svarta hål. Hur bildas atomerna som bygger upp oss människor - till exempel atomer av kol, syre eller kalcium? Den idag gâllande teorin är att lättare atomer såsom väte, helium och litium skapades vid "Big Bang", medan en supernova från en döende stjärna producerade och frigjorde bland annat kol, syre, kalcium och järn. Det som stjärnnor och Big BNucleosynthesis is the mechanism which produces new elements in nuclear reactions. Nuclear reaction rates are highly temperature dependant, and nuclear reactions take place in very hot environments. Current theories predict that the light elements such as hydrogen and helium were produced during the Big Bang. On the other hand, the core of stars produce heavier elements through nuclear fusion. The

By the beginning the second decade of twentieth century, a new regime came to power in Iran. While considering the Iranian society, her institutions, mechanisms and structures as a backward and dysfunctional one, the new regime started to set up a new order, based on modern values. In this case, old urban structures were among those aspects of the Iranian culture and society which were selected a

Allting är uppbyggt av atomer, inte bara träd, djur eller bläcket i dessa bokstäver, utan även astronomiska objekt så som stjärnor och planeter. Stjärnor är i princip extremt varma och kompakta moln av atomer, som skickar ut ljus i alla riktningar. Astronomer är intresserade av vilken sammansättning av atomer som bygger upp stjärnor eftersom detta hjälper dem att förstå hur stjärnor och galaxer biStellar abundances are important for understanding the chemical evolution of galaxies and provide us with constraints on stellar evolution and supernova nucleosynthesis. To determine stellar abundances accurately, atomic data is crucial. This data is incomplete for many elements, especially in the infrared region. In particular, hyperfine structure (hfs) data in the near-infrared region is lacking

Sverige präglas idag av en stark urbaniseringstrend, där inflyttning främst sker till våra tre storstadsregioner. Ett problem som försvårar urbaniseringen är att utbudet av bostäder inte möter den stora efterfrågan som uppstått. Byggbar mark i centrala lägen betraktas dessutom ofta som fullt ianspråktagen. På så vis har en diskussion om möjligheter att effektivisera markanvändningen uppstått. DettToday, Sweden is characterized by a strong urbanisation trend, where occupation mainly takes place in our three metropolitan regions, Stockholm, Gothenburg and Malmö. A problem that complicates the urbanisation is the fact that supply does not meet the demand of housing, which has arisen in these areas. In addition, buildable land in central areas is often considered to be fully claimed. Thus, a d

In recent years, Chinese corporate bond markets have grown at a remarkable rate. This thesis aims to examine the impact of corporate bond issuances on the momentum of stock prices by applying the event study. Our study comprises 212 corporate bond samples in the Chinese bond market from 2012 to 2016. Additionally, we investigate whether firm-specific and bond-specific characteristics correlate to

Denna uppsats avhandlar förvaltningen av dödsbo och det skydd som borgenärer har för sina fordringar både enligt ärvdabalken och enligt annan lagstiftning. Den rättsliga reglering som omgärdar dödsboförvaltning är till åren kommen och är i visst behov av att sättas i en nutida kontext. Uppsatsen utmynnar i slutsatsen att samtidigt som borgenärsskyddet är starkt, främst med avseende på ärvdabalkensThis thesis is about the administration of Swedish decedent estates and the creditors’ financial security of claims according to Swedish legislation. The legal regulation on the administration of descendent estates is dated and has some need to be updated. The findings of the thesis are as follows: the creditor’s security has a strong status, primarily due to the inheritance code’s requirement of

Materialet till studien kommer från Sveriges geologiska undersök-ning (SGU) som utfört geofysiska borrhålsmätningar och flygburna resistivitetsmätningar (SkyTEM) och från Olje-prospekterings AB (OPAB) som på 70- och 80-talet gjorde borrningar på Gotland i syftThis study aims to expand the knowledge about the bedrock in southern Gotland and link it to the strained groundwater situation that is there. The material for the study comes from the Swedish Geological Survey (SGU) which conducted geophysical borehole measurements and airborne resistivity measurements (SkyTEM) and from OPAB, which in the 70’s and 80’s drilled several wells on Gotland for the pur

Lignin accounts for 15 – 30 % of plant biomass, but is till today remarkably underutilized, mainly due to its heterogeneity and recalcitrance towards depolymerization. The bacterial conversion of lignin into value added chemicals is a highly promising approach to overcome this underutilization and can help to improve the economic competitiveness of the biorefinery concept. In the current study, 1

Det huvudsakliga syftet var att kartlägga motivationen hos yrkesarbetarna och tjänstemännen på ett grundläggningsföretag. Frågeställningen belyste skillnaden i motivationen beroende på vilken yrkestyp de har, vilken region de arbetar inom och vilken åldersgrupp, generation, de tillhör.

Undersökningen ficThe aim of the study was to map the motivational factors for blue collar and white collar workers at a construction company working on foundations and ground preparation. The question area sought to find differences in motivation depending on the type of work they do, which region they work in and their age group (generation). A questionnaire was sent to 128 employees at the company and 57 respond

The aim of this study was to examine the experiences of social workers working with unaccompanied refugee minors during the autumn of 2015, commonly referred to as the “refugee crisis”. During this period, Sweden received approximately 156 400 refugees, putting Sweden’s social infrastructure under enormous pressure. As a result of the stressful working conditions, a large amount of social workers

Today, the discussion regarding the environmental degradation is more active and pressing than ever. In Paris 2015, world leaders signed Agenda 2030, binding them to actively work to keep the global temperature increase below 2 degrees Celsius. This agreement also targets the need for sustainable energy for all humans. The purpose of this paper is to evaluate whether FDI has an effect on the consu

The ingredients generally used in the fermentation of probiotics tend to give an off-flavour to the fermentation product which is not ideal when producing e.g. fruit drinks. The aim of this master thesis was to evaluate if the concentration of such ingredients could be lowered and also to investigate whether there are other ingredients that could act as substitutes to those ingredients giving off-
