Context. Multi-planet systems are important sources of information regarding the evolution of planets. However, the long-period planets in these systems often escape detection. These objects in particular may retain more of their primordial characteristics compared to close-in counterparts because of their increased distance from the host star. HD 22946 is a bright (G = 8.13 mag) late F-type star

Given the current societal and political developments in Germany, the visibility and integration of-marginalized is essential to ensure their inclusion in mainstream society. One way of encouraging-contact between majority and marginalized groups is through building social networks, of which-informal and nonformal educational activities play an important part. This thesis examines the-experience o

Background: The global plant-based food shift puts high pressure on manufacturing capacity at facilities like Oatly's Landskrona site. This environment faces high combinatorial complexity due to growing product variety and sequence-dependent cleaning requirements. Relying on manual, experience-based planning to navigate these rules limits throughput and introduces organisational risk. Purpose

Childhood cancer aetiology is poorly understood and is considered to originate in utero and early postnatal life. In this study, we investigated perinatal characteristics as potential risk factors by performing a population-based case-control study, including 1340 cancer cases diagnosed < 19y and born between 1989–2021 in southern Sweden, and 13400 controls matched by sex, year, and municipality o

Biodiversity hotspots are biogeographic regions exceptionally rich in endemic species showing high rates of habitat loss, making them the priority of global conservation efforts. As part of the biodiversity hotspot with the highest density of endemic species, the West Usambara Mountains in Tanzania require an efficient and resourceful monitoring solution. This thesis aimed to model the tree specie

Popular Abstract in Swedish Bakgrund: Sedan Wilhelm Conrad Röntgen upptäckte röntgenstrålar 1896 utvecklades den diagnostiska röntgentekniken snabbt. Under första hälften av 1900-talet var användningen av joniserande strålning i form av röntgenstrålar den enda princip med vilken den allt mer tekniskt avancerade röntgendiagnostiken bedrevs. För att åskådliggöra blodkärl använder sig konventionell r

Syftet med uppsatsen är att redogöra för svensk rätt avseende ogiltighet av vilseledande avtal i förhållande till bluffakturor. Sedan tio år tillbaka har antalet polisanmälningar ökat markant rörande just bluffakturor, då finns det även ett stort mörkertal. Förutom att det drabbar många, är det betydande summor som årligen omsätts på grund av detta, således är detta ett ämne som förtjänar att belyThe purpose of this paper is to display Swedish law in regards to fake invoices and how these contracts under misleading agreements can be voided. The amount of police reports regarding fake invoices have increased significantly during the last ten years, one should also consider the big number of hidden statistics. Apart from the fact that it affects a lot of people it also has a high yearly turn

In order to fully understand the underlying processes of catalysis, it is vital to combine measurements of the catalyst surface, where the reaction occurs, with measurements of the gas concentration close to the catalyst. We have developed a convenient setup, which uses a single laser system to visualise the gas surrounding a working catalyst in situ at realistic operating conditions. Planar Lase

Heterologous overexpression of proteins signifies that the encoding gene of a protein in one organism is expressed in another host organism that normally does not have that gene in its genome. In basic biochemical research, this is an important method for studying various protein functions such as activity and interactions in biological processes, as well as obtaining sufficient amounts to determi

The increasing amount of renewable energy in the electrical grid comes with several challenges, of which overvoltage and congestion (overcurrents) are the subjects of this work. One flexible way of handling these problems is active management by some control system. There is a trade-off between simplicity when implementing the control system and the performance. In the project Active Network Manag

The transition from animal-based to plant-based proteins is rapidly increasing because of different concerns about meat consumption, some being the nutritional and environmental effects of meat consumption. During this transition, there needs to be a holistic approach to assessing plant-based food. This master thesis is focused on investigating the nutritional and environmental impact of three pla

Sweden’s grocery distribution is routed through a limited number of upstream hubs and relies on corridors and ferry links. When disruptions affect a hub or a critical link, reallocations propagate fast and travel times increase, with some areas losing coverage temporarily. Decentralising the whole system is costly, so targeted resilience options must be evaluated. The purpose of this thesis is to

Aircraft observations of precipitating clouds with cloud top temperatures higher than -38°C have revealed that Secondary Ice Production (SIP) is responsible for presence of majority of ice particles. One such SIP mechanism is fragmentation via collisions between ice particles. The central theme of this study is to understand the dependencies of this SIP mechanism and improve its existing numerical

Forests form the backbone of the European terrestrial carbon sink (State Forest Service & Ministry of Environment, 2018). As the European Union (EU) strives to become climate neutral by 2050, forests are accounted for the natural carbon absorption mechanism (European Commission, n.d.). Currently, the European net land carbon sink is decreasing largely due to forest ageing (Pilli et al., 2022),

With increasing demands on consumer products, attempts have been made to integrate all aspects of the product by the use of Cross-Functional Teams (CFTs) in product development work. However, research has shown that this integration often fails to reach its full potential. Considering the interdisciplinary interaction between industrial designers and engineering designers in CFTs, barriers p

Redan så tidigt som 1957 diskuterades frågan om fri rörlighet och hur man inom dåvarande EG kunde underlätta rörligheten för de fyra friheterna: personer, varor, kapital och tjänster. Till dags dato har EU rönt framgångar för tre av dessa fyra friheter, för tjänster är det dock fortsatt besvärligt. En process att undanröja de hinder som stod i vägen för tjänsters fria rörlighet inleddes av stats- As early as 1957 the issue of freedom of movement was discussed and how the EU could facilitate the movement of the four freedoms: people, good, capital and services. To date the EU has been successful for three of the four freedoms, however for services the situation remains difficult. A process to eliminate the obstacles that stood in the way of free movement of services was launched by heads of

Background: Mental distress is a major public health problem which includes anxiety, depression and somatic symptoms such as sleeping problems, fatigue and headache. University students are consistently reported to have higher levels of mental distress compared to the general population. Although university students with mental distress have significantly impaired cognitive functioning, learning d

Background:The optimal treatment of displaced femoral neck fractures in patients 55 to 70 years old remains controversial. The aim of the present study was to assess the effect of closed reduction and internal fixation with cannulated screws (IF) compared with total hip arthroplasty (THA) on hip pain and function, with use of data for outcome measures, complications, and reoperations.Methods:This
