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

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

Quenching of vibrational excitations in resonant inelastic X-ray scattering (RIXS) spectra of liquid acetic acid is observed. At the oxygen core resonance associated with localized excitations at the O–H bond, the spectra lack the typical progression of vibrational excitations observed in RIXS spectra of comparable systems. We interpret this phenomenon as due to strong rehybridization of the unocc

We present a detailed experimental-theoretical analysis of O K-edge resonant 1σ-2π inelastic x-ray scattering (RIXS) from carbon monoxide with unprecedented energy resolution. We employ high-level ab initio calculations to compute the potential energy curves of the states involved in the RIXS process and simulate the measured RIXS spectra using the wave-packet-propagation formalism, including Coul

This thesis explores the employer branding strategies of four major student nations at Lund University through their Instagram content throughout the year 2023. The focus is on how these organizations leverage organizational culture and rhetorical strategies—ethos, pathos, and logos—to engage current and prospective members. Utilizing a qualitative content analysis, it is examined how each student

The Drell-Yan (DY) process of dilepton pair production off nuclei is not affected by final state interactions, energy loss, or absorption. A detailed phenomenological study of this process is thus convenient for investigation of the onset of initial-state effects in proton-nucleus (pA) collisions. In this paper, we present a comprehensive analysis of the DY process in pA interactions at RHIC and L

Popular Abstract in Swedish Avhandlingen analyserar Guatemalas råvaruexport under perioden 1524-1945.In the integrated institutional-staples-‘vent for surplus’ approach, the opening of trade occurs because of initial demand. Once demand is determined, competitiveness is a function of transportation costs, entrepreneurship, capital, land and labour costs, as well as the role played by the State. When all these factors promote competitiveness within an institutional framework that decreased transac

Atomic (1 Å) resolution x-ray structures of horse liver alcohol dehydrogenase in complex with NADH revealed the formation of an adduct in the active site between a metal-bound water and NADH. Furthermore, a pronounced distortion of the pyridine ring of NADH was observed. A series of quantum chemical calculations on the water-nicotinamide adduct showed that the puckering of the pyridine ring in the

Economic institutions enabling trust and cooperation rest on multiplex networks and norms of reciprocity. A key feature of economic institutions is that they facilitate commercial transactions by reducing uncertainty and risk in markets. When trust and trustworthiness stem from confidence in community sanctions of norms, principal and agent relations are enforceable without resorting to legal rule

To remain competitive in the field of manufacturing today, companies must make their industrial robots smarter and allow them to collaborate with one another in a more effective manner. This is typically done by adding some form of learning, or artificial intelligence (AI), to the robots. These learning algorithms are often packaged as cloud functions in a remote computational center since the amo

Low energy buildings have well insulated building enclosures and efficient ventilation heat recovery systems which lead to small transmission and ventilation heat losses. During a large part of the year internal heat gains from people, household electricity and solar heat gains balance the heat losses with zero heating need as a result. All energy uses in a building are part of the buildings energ

The stability of the Nyström method for the Sherman–Lauricella equation on piecewise smooth closed simple contour $\Gamma$ is studied. It is shown that in the space $L_2$ the method is stable if and only if certain operators associated with the corner points of $\Gamma$ are invertible. If $\Gamma$ does not have corner points, the method is always stable. Numerical experiments show the transformati
