Detta examensarbete ämnar att undersöka integration av tre olika teknologier till en havsbaserad vindkraftspark, om det är ekonomiskt gynnsamt samt hur kraftfluktuationerna till elnätet påverkas. Genom att kombinera olika förnybara kraftsystem kan man minska variabiliteten och kostnaderna kopplade till installation och drift av systemen. Även fast investeringar i annan förnybar energi utöver vindkThe high penetration of wind power is increasing the intermittency and power variability into the existing power grid. This is forcing industries to look for optimal configurations in order to improve their systems performance and minimize these effects from the power production method. Studies show that there are different ways of reducing the power variability and therefore stabilize the energy

Objective: To describe the clinical and ultrasound characteristics of ovarian pure clear cell carcinoma. Methods: This was a retrospective study involving data from 11 ultrasound centers. From the International Ovarian Tumor Analysis (IOTA) database, 105 patients who had undergone preoperative ultrasound examination by an experienced ultrasound examiner between 1999 and 2016 were identified with a

Eddy covariance (EC) measurements are often used to validate net ecosystem productivity (NEP) estimated from satellite remote sensing data and biogeochemical models. However, EC measurements represent an integrated flux over their footprint area, which usually differs from respective model grids or remote sensing pixels. Quantifying the uncertainties of scale mismatch associated with gridded flux

Modern wind turbines are designed to withstand approximately for a lifetime of 20 years [1]. However, a very long design life of 100 years or more can be expected for high-quality concrete foundations. Thus there is a big difference in lifetime between wind turbines and foundations. There is a significant economic benefit of replacing the out-of-date wind turbine with a new turbine of better power

In an effort to mitigate global climate change, the REDD+ mechanism (an acronym for ‘Reduced Emissions from Deforestation and Forest Degradation plus the role of conservation, sustainable management of forests and enhancement of forest carbon stock’) continues to be put forward as an attractive carbon sequestration and forest conservation tool. The Democratic Republic of the Congo (DRC), hosting m

Methane emissions from Northern wetlands constitute a substantial part of the total natural emission of methane, a strong greenhouse gas. Both environmental and biotic factors influence the production, oxidation and transport of methane and hence its net flux. The methane emission from Northern wetlands is highly variable both spatially and temporally. As many factors influence the methane flux, k

Hur vi väljer att organisera våra familjer har genomgått en radikal förändring sedan mitten av 1900-talet. Kärnfamiljen är visserligen fortfarande den vanligaste familjeformen, men den har i allt större utsträckning kommit att kompletteras med en rad icke-traditionella familje-konstellationer, bl.a. samkönade familjer. Den här utvecklingen har naturligtvis också påverkat hur vi lever och praktisHow we choose to organize our families has changed significantly since the mid-20th century. It might be true that the nuclear family remains the most common family form. However, it has to an increasing extent been accompanied by a number of non-traditional families, including same-sex families. Naturally, this development has also affected the way we live and how we practice family life. While

Climate change has become a societal issue that has gained increasing attention in recent years. The Intergovernmental Panel on Climate Change, IPCC, presented in year 2007 its Fourth Assessment Report, pointing out different scenarios about the future climate, including the anticipated sea level rises during this century. More recent climate research has shown that sea levels are most likely to r

Over the last 30 years scientists have studied the morphological and mineralogical proofs of past aqueous activity on Mars. NASA’s latest flagship mission, the Mars 2020 mission with its Perseverance rover, landed in Jezero crater in 2021. Perseverance is tasked with investigating the wet history that has partially formed today’s Mars, and more specifically, find specific indicators for potential

Principen jura novit curia är en central och vedertagen princip i svensk processrätt och tillämpas i domstolsprocessen. Principens relevans och tillämpning i skiljeförfarande är dock inte lika självklar mot bakgrund av skiljeförfarandets syften och bakomliggande principer. Frågan om en skiljenämnd kan, bör eller ska tillämpa principen jura novit curia på motsvarande sätt som i domstolsprocessen akThe principle of jura novit curia is a central and well-established tenet in Swedish procedural law, applied within court proceedings. However, its relevance and application in arbitration is not as clear, given the purposes and underlying principles of arbitration. The question of whether an arbitral tribunal can, should, or must apply the principle of jura novit curia in the same manner as in co

Denna studie undersöker och besvarar huruvida det är mer värt ur ett ekonomiskt perspektiv att renovera ett 50-talshus i originalskick än att bygga ett nytt hus när samma krav på inomhusmiljö ställs. Kraven ställs främst på luftkvalitén, men gäller även värmedistribution och levnadssätt. För att få en generell bild och ett resultat som kan användas i övergripande sammanhang har två alternativa utfThis study examines and answers whether it is more profitable from a financial point of view to renovate a 1950s house in its original condition than to build a new house when the same requirements are made regarding the indoor environment. The demands are primarily set on the air quality, but they also apply to heat distribution and lifestyle/usage. In order to get the big picture and a result wh

Efforts to reduce energy consumption in buildings have increased with the pending impact of climate change. Heat losses through airing behaviours remain a largely unknown factor due to the variety of reasons for opening a window, making generalization difficult. Currently, an estimation of 4 kWh/m2 heated area for airing heat loss is assumed in Sweden. Additionally, the resulting airflow from open

Amelogenin, a critical protein in enamel formation, self-assembles into supramolecular structure that guide hydroxyapatite (HAP) crystal growth that is essential for the development of strong and healthy enamel. Phosphorylation of amelogenin at Ser-16 plays a pivotal role in modulating its self-assembly and functional properties, impacting the overall enamel biomineralization process. This post-tr

Global population growth presents challenges to sustainable food and energy produc- tion. Transitioning to renewable energy sources, like solar power, requires significant land allocations, conflicting with the need for arable farmland. Agrivoltaics (AV) offers a potential solution by integrating crops and solar panels on the same land. Ensuring consistent and adequate agricultural output alongsid

According to the Intergovernmental Panel on Climate Change (IPCC), atmospheric methane (CH4) concentrations are considered a crucial factor in global warming, particularly in the near term, due to its high warming potential (~ 80 times more potent than carbon dioxide, or CO2) and shorter atmospheric lifetime compared to CO2. CH4 emissions have more than doubled since the industrial revolution and

Stormwater runoffs have increasingly become a significant issue in urban infrastructure design and environmental management due to problems related to flooding, freshwater stress, and pollutant loading to receiving water bodies. This project investigated the lab-scale performance of silicon carbide (SiC) MF membranes in treating stormwater runoffs from the Värpinge wetland in the western part of t

The report, designed for interested parties of the industrial food industry in France, is founded on three research questions inspired by literature studies of sustainable development, management of corporate social responsibility, industrial food production and food product quality. The research questions search for the identification and explanation of critical categories of concern relevant for

Dalby Söderskog är belägen tio kilometer öster om Lund och har varit nationalpark sedan 1918. Växtligheten består av ädellövträd samt en rik vårflora av bland annat vitoch gulsippor och skånsk nunneört. Sommaren 1921 utfördes en taxering av skogen och en karta upprättades (figur 1). Kartan visar Söderskogens utbredning samt varje träd i densamma. Arbetet grundar sig på just denna karta men tar äveThe national park Dalby Söderskog is situated ten kilometres east of Lund and has been a national park since 1918. The vegetation consists of a deciduous forest of Oak, Beech, Elm, Ash and Alden. The forest is also famous thanks to its rich spring flora of among others Anemóne nemorósa, Anemóne ranunculoídes and Corýdalis bulbosa. In the summer of 1921 a map was drawn that shows the distribution o
