Because of their small size, great abundance and easy dispersal, it is often assumed that marine planktonic microorganisms have a ubiquitous distribution that prevents any structured assembly into local communities. To challenge this view, marine bacterioplankton communities from coastal waters at nine locations distributed world-wide were examined through the use of comprehensive clone libraries
Background How DNA repair enzymes find the relatively rare sites of damage is not known in great detail. Recent experiments and molecular data suggest that individual repair enzymes do not work independently of each other, but interact with each other through charges exchanged along the DNA. A damaged site in the DNA hinders this exchange. The hypothesis is that the charge exchange quickly libera
The transport sector needs to become sustainable and public transport has an important role to play. Green public procurement has proven to have great potential to influence the transition to a sustainable public transport sector. Sweden is a good example of a country that uses public procurement in the public transport sector to a large extent and has at the same time come far in the transition t
The present study experimentally demonstrates a novel design for an internal endwall in a two-pass duct heat exchanger. An array of delta-winglet vortex generator pairs with different aspect ratio, angle of attack, configuration are mounted on the internal endwall in a U duct. Liquid crystal thermalgraphy and static pressure measurements are utilized in this study to evaluate the heat transfer, th
Myoelektrisk kontroll av handprotes Att förlora en hand är en stor förlust och även om allt mer avancerades proteser tillverkas är de fortfarande långt ifrån att prestera lika bra som en riktig hand. För att kunna styra handproteser på ett intuitivt sätt används myoelektrisk kontroll. En metod där man spelar in kroppen muskelsignaler och översätter dem till signaler som kan styra t.ex. en robothaThe goals of this project are to investigate the viability of using the MyoTM armband developed by Thalmic labs as a tool for myoelectric control of a hand prosthesis as well as investigate whether the armbands ability to record its spatial position and orientation can be used to increase the performance of the prosthesis control program. Using the surface electrodes, gyroscopes and accelerometers
The purpose of this practical theological master’s thesis is to examine conversation as part of sermon preparation in present day preaching in the Lutheran Church of Sweden. This study combines studies of homiletical literature with qualitative empirical methods, stating that theory and practice informs one another. Through participant observation in Bible study groups and the following Sunday’s s
This thesis have examined the Region of Skåne, and its work within the EU. The analysis unit in focus is the Skåne European Office, which is the representation office of the region in Brussels. The aim of the thesis has been to examine their lobbying and networking in Brussels. The question asked is: “How does the region of Skåne exercise their lobbying and networking through their office in Bruss
Denna uppsats är skriven på uppdrag av Lunds tekniska högskola och Myndigheten för samhällsskydd och beredskap. Uppdraget består av att modellera antalet dödsbränder som sker i Sverige över tid, samt undersöka ifall det har skett någon signifikant förändring. Detta görs utifrån ett antagande om att dödsbränder är Poisson-fördelade, därmed betraktas antalet dödsbränder över tid som en Poisson-proceThe authors of this thesis were tasked with modelling fatal fires in Sweden to answer the question, whether the quarterly number of fires has changed over time. The usage of the Poisson distribution in modelling accidents and mortalities is well attested. Problems arise when measuring the number of fire related mortalities, as several deaths can be attributed to one fire. This violates the assumpt
In 2016 Max Abrahms and Justin Conrad published a study that resulted in a theory regarding anonymous terrorist attacks. Terrorism is a political communication strategy used by groups to communicate their grievances and the cost of ignoring them. In practice, however, terrorist groups only take responsibility for a small fraction of all attacks. Terrorist leaders are not honored for the violence a
Syftet med denna litteraturstudie var att undersöka det vetenskapliga stödet for familjeterapi och familjebaserade interventioner vid behandling för depression hos barn och ungdomar. Dessutom ville vi belysa hur olika forskningsperspektiv och utfallsmått kan påverka rekommendationerna för val av behandling. Nio artiklar undersöktes och bedömdes efter dess vetenskapliga kvalitet. Fem av artiklarna The aim of this literature study was to examine the evidence of family therapy and familybased interventions for children and adolescents with depression. Additionally, this study highlights how different research perspectives and outcome measures may affect the recommendations of treatment interventions. Nine articles were reviewed and assessed for their scientific quality. Five of the articles w
This thesis examines how active power control (Volt-Watt control) and reactive power compensation (Volt-VAr control) can help limit voltage increases on the low voltage grid due to high photovoltaic (PV), installations. Due to the large increase in interest to install small scale PV-systems within residential areas the Distribution System Operator E.ON, has noticed problems concerning high voltage
This master thesis presents a suggested Renovation Passport for two typical 1960s single-family houses. Following the recently approved Energy Performance of Buildings Directive (EU 2024/1275A), all member states are to implement voluntary Renovation Passports by 2026, which will aid in reaching the 2050 goal of a decarbonized building stock. The aim of Renovation Passports is to provide long-ter
The European Spallation Source (ESS) infrastructure is being constructed in Lund, and will be one of the most powerful research facilities of its type in the world. The ESS linear accelerator (linac) utilizes different accelerating sections where a wide variety of techniques should be employed to accelerate a beam of protons to 2 GeV kinetic energy through Radio Frequency (RF) cavities before bein
The purpose of this study was to explore medically trained care givers’ views on their work with people with dementia, focusing on their professional discretion and the standardized tools they use in their daily work. The aim was to gain a deeper understanding of aspects of their work that overlap with social work. The method used was qualitative semi-structured interviews with six caregivers, wor
It is widely recognised that the two major challenges of the 21st century are climate change and poverty. The building sector is responsible for over a third of all global carbon dioxide emissions. At the same time, we see vastly overcrowded and rapidly growing informal settlements in developing countries, where people lack the basic right to decent shelter. This is simply not sustainable and forc
Studies on how small states act within the international system are usually performed using the major theories in international relations. After Russia’s invasion of Ukraine in 2022, Sweden applied for a membership in the North Atlantic Treaty Organization (Nato). This thesis’s purpose is to gain knowledge on how strategic narratives were used to legitimize policy changes in a nation that has been
The study is compiled into a composite index for assessing the climate vulnerability of African nations. By employing a multidimensional approach, the index comprises nine distinctive hazards to examine a country’s sensitivity to climate change. These hazards are divided into three categories; acute physical hazards, chronic physical hazards and systemic hazards. This index structure is based on t
I studien undersöktes associativ språkinlärning via Virtual Reality (VR) och jämfördes sedan med en mer traditionell ordinlärning via en datorskärm, för att se om det förekom någon skillnad i inlärningen mellan dessa. Syfte. Studien syftade till att undersöka om inlärning av ett nytt språk gynnas av associativ inlärning med flera av våra sinnen genom VR. Vår hypotes var att språkinlärning kan gynThe study examined associative language learning through Virtual Reality (VR) and then compared it to more traditional word learning through a computer screen, in order to see if there was any difference in learning between these two. Purpose. The aim of this study to investigate whether learning a new language benefits from associative learning, with several of our senses, through VR. Our hypoth
Har verkligen denna nya fälla för nattfjärilar vad som krävs för att störta den äldre modellen? LED har börjats använda i större grad bland levandefällor för nattfjärilar, och Lunds Universitet har förut endast köpt en sådan typ av fälla från Nederländerna. Men numera har en liknande version med möjlighet till mer ljus byggs vid Biologiska Insitutionen i Lund, och test har visat att nattfjärilarnaDue to the increasing significance of moth species’ contributions to pollination, and the relatively new advancements of AI and LED within this field of study, there is interest in developing a light trap that is both easier to get a hold of and more adapted to the conditions of a northern country like Sweden. In this study I evaluate one such LED-based Light trap and compare it to a more well-tes
The 2022 centenary of the ‘liberation of Izmir’ saw no less than three municipally organised exhibitions thematising historic events long avoided in official memory: the Great Fire of 1922, and the ensuing Turkish-Greek population exchange. Incongruent with the tale of national triumph and unity, such disasters and displacements have been systematically repressed in Turkish official memory, brough
