Målet med detta projekt var att studera två sorters bakterier, Actinobacillus succinogenes och Basfia succiniciproducens, och deras produktion av bärnstenssyra. Bärnstenssyra är en dikarboxylsyra som även är en metabolit i citronsyracykeln. Den kan användas som surhetsreglerare i mat, för att producera andra bulk-kemikalier och för att producera bio-plaster. De två bakteriearter som undersöktes i The aim of this project was to study two bacterial species, Actinobacillus succinogenes and Basfia succiniciproducens for production of succinic acid. Succinic acid is a dicarboxylic acid and a metabolite in the citric acid cycle. It can be used as a food additive, to produce bulk chemicals and to make bio-based plastic (PBS). The two bacteria examined in this work need carbon dioxide to produce s

In this study global wave climates for present and future climates are simulated with the WAM model, based on wind fields from the JMA/MRI-AGCM3.2 climate projection. The projected wave fields are analysed and compared for the two periods of 1979-2003 and 2075-2099, and climate change induced differences are identified. It is found that the wave climate is strongly dependent on latitude, with the

Detta arbete undersöker processrättens roll på det migrationsrättsliga området, så som den kommer till uttryck genom ett antal migrationsprocessrättsliga särdrag. Centralt för undersökningen är hur avvägningen mellan de motstående intressena individens rättssäkerhet och processuell effektivitet har gjorts i migrationsprocessen. Den första särdraget som behandlas är den på det migrationsrättsliga This essay examines the role of procedural rules in the field of Swedish migration law, as this role is expressed through a number of procedural features that are special for migration law. The essay focuses on whether the procedural rules of Swedish migration law tend to prioritize the individual’s procedural safeguards or procedural efficiency. The first unique feature of the procedural rules o

The focus of this work has been to implement a generic netlist reduction engine to speed up circuit simulations. The netlist reduction techniques are further optimized for Static Random-Access Memory (SRAM), wherein we exploit the repetitive pattern of the circuit. There are many driving factors for developing a netlist reduction engine for SRAM simulations. In today's System on Chip (SoC), S

The aim of the study at had was to explore the potential of Natural Capital Accounting (NCA) to integrate environment into business decision-making. In order to fulfill the aim, the research was split into three main parts. First, the existing views on what constitutes NCA were reviewed through a literature analysis of grey literature, and the working definition established. The study found that t

With the climate change and urbanization process, the frequency of the urban flooding’s occurrence has increased in the recent years. It brings great economic losses to the cities, especially to the basements of individual properties. Low Impact Development (LID), which currently advocated by more city planners for managing stormwater, is considered as a more sustainable way to mitigate urban floo

Alla lastbärande delar har modellerats med limträ av klassen GL30c och med dimensionerna 0.8×1.6 m2. Lastfallen valdes till 2 kN/m2 respektive 4 kN/m2 för symmetriska och asymmetriska snölaster. De numeriska beräkningarna utfördes i finita element-mjukvaran Abaqus FEA och The aim of this thesis is to study the feasibility of building a timber dome with a span of 300 metres, concerning elastic stability. The load-bearing members were modelled with the properties of glued laminated timber GL30c with the dimensions 0.8×1.6 m2. The design loads were 2 kN/m2 and 4 kN/m2 in symmetrical and asymmetrical load cases, respectively. The numerical calculations were performed u

Att vittna är en lagstadgad skyldighet i Sverige. Om man vägrar att inställa sig som vittne trots att man är kallad riskerar man att tvångsmedel riktas mot en. Under senare tid har möjligheten till anonyma vittnesmål diskuterats på en rad olika håll i samhället, då man allt oftare ser en ovilja att vittna på grund av rädsla att drabbas av repressalier. Enligt en allmän uppfattning är det inte tillTo testify is a statutory duty in Sweden. If one refuses to testify, even though one are called by the court, one risks that compulsions will be directed towards one. Recently, the possibility of anonymous testimony has been discussed in the Swedish society, as the reluctance to testify has increased due to the fear of reprisals. But according to the general view in Sweden, it is not allowed to wi

Poxviruses are large, double-stranded DNA viruses that replicate directly in the cytoplasm of the host eukaryotic cell. During assembly of viral particle progeny, viral membrane precursors derived from the endoplasmic reticulum, exhibit stabilised open ends inside intermediate structures called crescents. The process of viral membrane biogenesis during poxvirus assembly remains poorly understood.

The aviation industry continues today to be one of the main sources of green house gas emission. In order to counteract this trend, certain solutions are being invested in with one of these being the use of electro-based sustainable aviation fuels. Its drop-in ability and potential for reduction in emissions present eSAF as one of the most attractive and viable alternatives to decarbonisation of t

Sustainability reporting remains a well-established field of research, with many important contributions. Additionally, the public has a growing desire for firms to adopt responsible ESG practices, thus requiring more transparency and accountability. Without the acceptance from the public, the business might face negative consequences. The understanding of how sustainability reporting is disclosed

Climate change is intensifying globally, leading to rising temperatures. The Arctic being a vulnerable and extreme environment faces an enhanced warming effect, referred to as the Arctic amplification. In this rapidly changing environment, high amounts of carbon (1,460 – 1,600 Pg C) are stored in permafrost. This is four times the amount of carbon being emitted by humans in modern times. Increasin

Den 1 juli 2022 trädde en ändring av lagen (1988:254) om förbud beträffande knivar och andra farliga föremål, även kallad knivlagen, i kraft. Denna innebar bl.a. att kvalifikationsgrunder infördes för bedömningen av om ett brott ska rubriceras som grovt, och att straffskalan för grovt brott skärptes till fängelse i lägst sex månader och högst två år. Syftet med den här uppsatsen är att analyseraOn 1 July 2022, the Swedish Act (1988:254) on the Prohibition of Knives and Other Dangerous Objects (the Swedish Knife Act), which criminalizes possession of knives and other dangerous objects in public places, was amended. Through the amendment, four criteria were introduced to the statutory text, which are to be given particular consideration when assessing whether a violation of the law is to b

This study explores how Lund University students navigate everyday food purchasingdecisions in order to better understand young consumers’ needs and behaviours. As Europeanfarmers face growing competition from cheaper imported goods, understanding consumerbehaviour becomes increasingly important for creating more sustainable and locally resilientfood systems (Loughlin, 2024). Students were selecte

Stellar 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

BIM, byggnadsinformationsmodellering, är ett arbetssätt som blir allt vanligare. Det innebär att olika objekt bygger upp en övergripande 3D-modell där man kan finna mängder av information om dessa objekt. Ett objekt kan vara allt ifrån en bropelare till en elstolpe. Syftet med denna rapport är att utifrån Trafikverkets roll som beställare undersöka vilka för- och nackdelar det skulle innebära med BIM, Building Information Modeling, is an increasingly common way of working. This means that different objects build up an overall 3D-model where you can find lots of information about these objects. An object can be anything from a bridge pillar to an electric pole. The purpose of this report is to, based on the Swedish Transport Administrations’ as a client, investigate the advantages and disad

Introduction: This study attempts to optimize the choice of stationary phase for the separation of lignosulfonate lignin compounds using supercritical fluid chromatography coupled to mass spectrometry. Background: Lignin is a potential renewable source of phenolic compounds. Lignosulfonate lignins are produced during pulping processes producing very complex mixtures, which are challenging to anal

Ever since the dawn of internet, a new wave of fast-growing software companies has emerged. The M&A scholars have struggled to find appropriate valuation mechanisms for unprofitable companies with ultra-high revenue growth. To overcome the uncertain future, a contractual provision called earnout is often used. An earnout is a contractual provision in a M&A-deal that states the seller of th
