Det finns flertal fall då grafdatabaser överträffar traditionella relationsdatabasers pre-standa. Är grafdatabaser potentiellt den nya lagringsmetoden vid stor mängd sam-mankopplad data? Vilka villkor krävs? För att sätta det på prov har vi skapat entestmiljö med en stor mängd relationsbunden data.In an age of increasing usage of heavily interconnected platforms, graph databases have increased in popularity due to their ease of modelling these systems. This thesis will evaluate if the graph database Neo4j can be used to model Lime's CRM System efficiently by comparing the performance of Neo4j and MS SQL on queries similar to those existing in Lime CRM. To benchmark the databases, they w

Människokroppen är uppbyggd av olika typer av celler som exempelvis hudceller, nervceller och fettceller. Generellt sett är dessa celler utformade för en väldigt specifik uppgift såsom att utföra arbete (exempelvis muskelceller) eller att förse kroppen med struktur (exempelvis benceller). Det finns en väldigt spektakulär typ av cell -- så kallade stamceller -- vars specifika syfte är att omvandlasThe generation of induced pluripotent stem (iPS) cells from differentiated cells is a process of great scientific interest due to the medical potential of such cells. This process (called 'reprogramming' of cells) is however notoriously inefficient and still not very well understood. Therefore studies that can help us understand the interactions and mechanisms governing the reprogramming p

Governance and ideology have significant influence on how problems and policies are conceptualized. This conceptualization affects the way in which political subjects are formed and how individuals regard themselves. In this paper we approach environmental policy from a post-structuralist stance. Our ambition is to demonstrate a paradoxical relationship between the current consumer oriented repres

The implementation step of environmental policies has often been disregarded by researchers, who mainly focused on the policy-making process. Yet, implementation is crucial for the success of a policy. We looked at the influence of domestic factors in the implementation process to explain how countries members of the European Union that have similar administrative capacities yet obtain different i

Det är inte ovanligt att parterna i en nationell tvist kommer från olika länder. När en tvist mellan parter med olika internationell anknytning initieras uppkommer ibland frågor om vilket lands domstol som är behörig att pröva tvisten och vilket lands lag som ska gälla för tvisten. En något mer undanskymd fråga inom det internationella rättssamfundet, men som likväl kan ge upphov till jurisdiktionIt is not uncommon for parties to a domestic dispute to come from different countries. When a dispute between parties with different international connections is initiated, questions sometimes arise as to which country’s court has jurisdiction to hear the dispute and which country’s law should apply to the dispute. A somewhat more obscure issue within the international legal community, but which c

I denna analys undersöker vi Sverigedemokraternas valframgång i kommunvalet i Landskrona 2006. Vi använder oss av tre olika sorters material: artiklar och insändare från Landskronaposten, valmaterial från de efter valet fyra största partierna, samt kvalitativa intervjuer med folkvalda och civilsamhällegrupper. Studien är hypotesprövande, där vi utifrån tre teser undersöker vårt material. Vi studer

This thesis investigates the evolving legal status of Sports Governing Bod-ies (SGBs) like UEFA and FIFA under EU law. It specifically questions whether their regulatory frameworks and practices align with EU competi-tion law and free movement principles. The research heavily relies on the analysis of recent pivotal court decisions, including the December Rulings and Diarra. The thesis begins by

We purified a laccase isoenzyme, Lad 1 from Galerina sp. HC1 using a combination of anion exchange- and hydrophobic interaction chromatography. Lad l has a molecular mass of 64 kDa, an isoelectric point of 4, and 3.35 copper atoms/enzyme molecule. The enzyme has features typical of fungal blue laccases. The sequences of two internal peptides were highly similar to reported laccase sequences from o

Modification of the resonance fluorescence spectrum of a two-level atom driven by a monochromatic field in the close proximity of a plasmonic nanostructure (metal sphere) is studied in detail. It is shown that one can control this spectrum by varying several key parameters: (i) the radius of the nanosphere, (ii) polarization of the incident radiation, and (iii) the atom's location around the nanos

This study reports findings from the first large-scale experiment investigating whether entrepreneurs differ 1 from other people in their willingness to expose themselves to various forms of uncertainty. A stratified random sample of 700 chief executive officers from the Yangzi delta region in China is compared to 200 control group members. Our findings suggest that in economic decisions, entrepre

In this work, we investigate production of Drell-Yan (DY) pairs in proton-nucleus collisions in kinematic regions where the corresponding coherence length does not exceed the nuclear radius, RA, and the quantum coherence effects should be treated with special care. The results for the nucleus-to-nucleon production ratio available in the literature so far are usually based on the assumption of a ve

Migraines constitute a common neurological and headache disorder affecting around 15% of the world’s population. In addition to other mechanisms, neurogenic neuroinflammation has been proposed to play a part in migraine chronification, which includes peripheral and central sensitization. There is therefore considerable evidence suggesting that inflammation in the intracranial meninges could be a k

A parsimonious set of mechanisms explains how and under which conditions behavioral deviations build into cascades that reshape institutional frameworks from the bottom up, even if institutional innovations initially conflict with the legally codified rules of the game. Specifically, we argue that this type of endogenous institutional change emerges from an interplay between three factors: the uti

Background: The secreted enzyme EndoS, an endoglycosidase from Streptococcus pyogenes, hydrolyzes the N-linked glycan of the constant region of immunoglobulin G (IgG) heavy chain and renders the antibody unable to interact with Fc receptors and elicit effector functions. In this study we couple targeted allelic replacement mutagenesis and heterologous expression to elucidate the contribution of En

We consider several simple combinatorial problems and discuss different ways to express them using polynomial equations and try to describe the Gröbner basis of the corresponding ideals. The main instruments are complete symmetric polynomials that help to express different conditions in rather compact way.

Syftet med uppsatsen är att finna och konkretisera möjliga faktorer som bidrar till en framgångsrik nyemission hos onoterade företag i Sverige. De faktorer kan på förhand hjälpa onoterade företag att anpassa organisationen och emissionsvillkoren till att ha så bra förutsättningar som möjligt för att genomföra en framgångsrik nyemission. Vi har utifrån en deduktiv ansats gjort en kvantitativ unders
