Climatic condition is what ultimately frames all ecosystems and is now undergoing dramatic change. IPCC models predict, in 100 years, a temperature increase between 2-5 ˚C and, as a consequence of warmer and wetter conditions, increased humic content in northern temperate freshwater systems. To study the impact of increasing temperature and humic content on shallow freshwaters a long-term outdoor

The tradeoff between risk and return is a topic that most investors consider carefully before an investment decision is made. Markowitz’s pioneer work on portfolio selection using the mean-variance framework has entailed a great extent of research in this field. One research is the Sharpe ratio, which is a measure of a financial performance using variance as a risk measure. The shortcoming of vari

The number of accidents in the construction industry has always been high and despite the many efforts made by national legislation and the companies themselves they remain alarmingly so. The purpose of this report is to examine how workers see their own working-environment and how they think that safety performance on construction sites may be improved. This is achieved by conducting interviews w

In Nepal, dams have been targeted as the most viable means of energy generation. However, dam projects often necessitate the relocation and resettlement of people to make way for reservoirs; processes that may pose great challenges for affected people, given that their homes, land, and livelihoods are lost to some extent. This thesis analyzes the challenges facing the Nepali state in ensuring th

Att undersöka stjärnor i infrarött är en relativt ny företeelse till skillnad från optisk astronomi (dvs. synligt ljus). Det var först på 60-talet med teleskopet Stratoscope II som man lyckades få spektra från stjärnor i infrarött (våglängder på runt 3 m), och upptäckte förekomsten av vatten i kalla röda jättar. Den bakomliggade problematiken till varför modern infraröd astronomi är så ungt är våThe advent of infrared astronomy, unlike optical astronomy that was developed over centuries, was delayed until the space age due to our own atmosphere acting as an efficient shield towards this radiation. With a lot of molecules (including water) emitting in the infrared region, it was first in the late 1990s that water no longer was deemed special and was observed in many cooler (K-M) giant star

I november 2021 beslutade den dåvarande regeringen att tillsätta en utredning för att göra en översyn av regleringen om frihetsberövande påföljder för unga. I augusti 2023 publicerades utredningen som ställer sig positiv införandet av s.k. ungdomsfängelser. Den frihetsberövande påföljd som i nuläget finns för unga lagöverträdare (15–17 år), utöver fängelse, är sluten ungdomsvård (och stadgas i 32 In November 2021, the Swedish government at the time decided to appoint an inquiry to review the regulations on custodial sanctions for young people. In August 2023, the investigation was published, which is in favor of juvenile prisons. The custodial sanction that currently exists for young offenders (15-17 years old), in addition to imprisonment, is "closed youth care" (and is stipulat

Klimatförändringar i kombination med förtätning av städer kommer leda till ökade översvämningsrisker i stadsmiljö. Hållbar dagvatten- hantering kan bidra till att minska dessa risker och innebär att ytligt avrinnande vatten fördröjs så nära källan som möjligt, fördelaktligen genom naturbaserade lösningar. Kvartersmark utgör ungefär 70% av marken i svenska städer och det saknas såväl tydlig lagstifThe combination of climate change and urban consolidation will lead to increased risk of pluvial flooding in urban environments. Sustainable stormwater management can decrease these risks by using measures for surface runoff to be detained locally, preferably through nature based solutions. Private properties constitute about 70% of the land in Swedish cities and there is a lack of clear legislati

A guide in the darkness; A system shedding light on mRNA pseudouridylation by PUS7 Proteins, the building blocks of life, are produced from messenger RNA (mRNA). mRNA is built by four ribonucleotides, namely adenine (A), guanine (G), cytosine (C) and uridine (U). Interestingly, RNA includes also chemically modified versions of the above nucleotides affecting many physiological processes. The most

The upcoming Light Dark Matter eXperiment (LDMX) aims to push new frontiers in the search for the nature of dark matter. Its electromagnetic calorimeter (ECal) can be calibrated directly from the electron beam in the experiment, however the hadronic calorimeter (HCal) will be installed behind and to the sides of the ECal. Thus, it cannot be calibrated directly and has to be done so through other m

In the past, absolute monarchy was the most common form of government across the world. Since then, we have seen a great decline in this specific government type. However, in a world that still consists of several autocratic regimes, some absolute monarchies still remain. Not only do they exist in a time of democracy and autocracy, but they are also considered to be the most stable form of autocra

Uppsatsen undersöker dels förhållandet mellan behovs- och försäkringsprin-cipen i förslagen till 1913 års lag om allmän pensionsförsäkring, dels den syn på rätten som juristerna i riksdagsdebatten hade. Undersökningen går direkt till primärkällorna och både förslagen och kammardebatterna undersöks ifrån ett rättshistoriskt perspektiv. Uppsatsen redogör för de från detta perspektiv sett relevanta dThe essay examines both the relationship between the principle of need and the insurance principle within the draft law for the 1913 pensions act and the view of the law held by the legal practitioners within the parliament. The primary sources are examined directly and both the content of the draft and the debates in the chambers of the parliament are reviewed through a legal historical lens. Fro

Vid byggnation av vägar och järnvägar i Sverige idag används nästan uteslutande ändliga resurser som bergkross eller naturgrus som ballastmaterial. Det är av stort intresse att undersöka om till exempel återvunnet material och restprodukter från industrier skulle kunna användas i stället. För detta ändamål byggdes en testväg i november 2024 inne på en avfallsanläggning i Helsingborg. Vägen, som foDuring construction of roads and railways in Sweden today, mainly finite resources such as crushed rock or natural gravel, are being used as ballast material. It is of great interest to investigate whether, for instance, recycled materials and residual products from industries could be used instead. For this purpose, a test road was constructed in November of 2024 in a waste facility in Helsingbor

I uppsatsen undersöks lagregleringen om överskottsinformation vid användning av hemliga tvångsmedel i rättegångsbalken. Överskottsinformation är information som har med annat att göra än den utredning den hemliga tvångsåtgärden användes för. Lagändringen år 2023 innebär att informationen uttryckligen får användas för ”andra ändamål” än den ursprungliga utredningen vilket kan avse brott eller helt The essay examines the legal regulation on excess information when using secret measures of surveillance in the Code of Judicial Procedure . Excess information is information that pertains to matters other than the investigation for which the secret measure of surveillance was used. The 2023 legislative amendment explicitly allows the information to be used for “other purposes” than the original i

Bakgrund: Kulturhistoriska byggnader har ett särskilt historiskt, estetiskt eller socialt värde och skyddas av regler som begränsar förändringar. Med rätt byggnadsvård och tekiska lösningar kan bevarande kombineras med energieffektiviseringar. Även om bevarande ofta innebär högre initiala kostnader, kan det ge långsiktiga värden både kulturellt och ekonomiskt. Syfte: Syftet är ett undersöka hur kThroughout history, construction practices have reflected the materials, knowledge, and economic resources available at the time. These historical characteristics are now seen as cultural assets worth preserving. However, older buildings often fail to meet modern standards, necessitating significant interventions to comply with today’s regulations. This thesis explores the challenges and opportun

Mental health issues are a serious matter with great consequences on livelihoods. Iraqi Kurdistan is situated in one of the most unstable regions and experienced an influx of IDPs over time who are in need of mental health support. However, mental health support is shaped and understood differently according to the culture. The purpose of this research is therefore to investigate the consequences

Cutting carbon emission from road transports worldwide is a key component in limiting global warming, and electrification is one of the most likely automotive technologies to achieve this goal. Therefore, Elonroad is developing an electric road system that will allow its users to charge while driving. This allows greater range and a reduction in battery sizes. This master thesis is therefore aimin

Inom fastighetsrätten är begreppet fastighet centralt. Fastighetsrätten utgår ibland från fastighet och ibland från andra begrepp så som brukningsenhet, tomt och värderingsenhet. Ibland används begreppen som synonymer till fastighet vilket försvårar tolkningar av diverse lagar. Jordabalken definierar vad en fastighet är och fastighetsbildningslagen anger hur fastigheter bildas och ändras. Plan- oIn Swedish real estate law, the concept of real property is central. Real estate law sometimes refers to real property and sometimes to other concepts such as farm unit, plot, and valuation unit. Sometimes the terms are used as synonyms for real property, which complicates the interpretation of various laws due to conceptual confusion. An example of conceptual confusion is when owners of real pro

Introduction: In Bio-pharmaceutical production, peristaltic pump tubing is considered one of the factors that influence protein aggregation. Background: Protein particles present challenges for the control and analysis of various manufacturing processes in the biopharmaceutical industry for their significant effects on safety and quality. Aim(s): This research aims to study the effect of differe

Vårdnadsreglerna, framför allt regleringen om gemensam vårdnad, har gjort en omfattande utvecklingsresa från 1970-talet och framåt. Uppsatsen syftar till att belysa, med en rättsdogmatisk metod, vilka förändringar som gjorts och vilket perspektiv som ligger bakom dem. Regleringen har gått från att gemensam vårdnad enbart var aktuellt för gifta föräldrar, till en presumtion om att gemensam vårdnad The Swedish custody regulations can be found in the Children and Parents Code. These rules have gone through a huge development during the modern times. This essay aims to illustrate which changes has been made and the perspectives behind them. The regulation has gone from joint custody for married parents only, to a presumption that joint custody always shall apply and on to that the custody shal

I detta examensarbete görs en utvärdering av ankomstprognoser för tåg för att se hur de olika prediktionskällorna står sig mot varandra och hur pass väl dessa efterspeglar verkligheten. Vidare är detta examensarbete en sprint av ett forskningsprojekt som genomförs och bedrivs på Lunds Tekniska Högskola på uppdrag av Trafikverket. Till skillnad från forskningsprojektet bygger detta examensarbetIn this master thesis, an evaluation of arrival forecasts for trains is made to see how various prediction sources compare to each other and how well these reflect reality. Furthermore, this thesis is a sprint of a research project that is carried out and conducted at Lund University of Technology on behalf of the Swedish Transport Administration. Unlike the research project, this thesis is based
