We investigate the hypothesis that ingestion of a terrestrial or super-Earth planet could cause the anomalously high metal abundances seen in a turn-off star in the open cluster M67, when compared to other turn-off stars in the same cluster. We show that the mass of the convective envelope of the star is likely only 3.45 × 10-3 M⊙, and hence 5.2 M⊙ of rock is required to obtain the observed 0.128
octurnal lepidopteran pollinators face pesticide exposure risks in agricultural landscapes, yet lack adequate risk assessment frameworks compared to diurnal species. We present a formal model description for Noctua pronuba within the Animal Landscape and Man Simulation System (ALMaSS), providing the first comprehensive agent-based framework for assessing the impacts of pesticides on nocturnal mothNocturnal lepidopteran pollinators face pesticide exposure risks in agricultural landscapes, yet lack adequate risk assessment frameworks compared to diurnal species.

Objective: To report the use of a percutaneous carotid access with vessel closure devices (VCDs) during complex endovascular aortic arch repair. Methods: Seven international high-volume centers conducted a retrospective review of all patients receiving percutaneous carotid access with VCD during endovascular aortic arch procedures to investigate its feasibility and safety. The primary end point wa
Rapporten sammanfattar fjärilsinventeringar utförda 2020 inom Biogeografisk uppföljning som drivs av Naturvårdsverket. I fjällområdet kunde totalt 49 ytor inventeras. Sammanlagt noterades 151 högnordiska blåvingar på 22 inventerade ytor, 53 dvärgpärlemorfjärilar på 25 ytor och minst 1 fjällsilversmygare noterades på 3 inventerade ytor. Svartfläckig blåvinge observerades på 15 av 50 inventerade lok
Due to relatively low patronage levels, rural bus stops are sometimes questioned in order to improve travel time and reliability on regional bus services. Previous research into stop spacing has focused on urban areas, which means that there is a lack of knowledge regarding the effects of bus stops in regional networks, with longer distances, higher speeds, and lower passenger volumes, in general.
The present work performs unsteady Reynolds-averaged Navier-Stokes simulations to study the effect of turbulence-chemistry interaction (TCI) on diesel spray flames. Three nozzle diameters (d0) of 100, 180, and 363 μm are considered in the present study. The Eulerian stochastic fields (ESF) method (with the TCI effect) and well-stirred reactor (WSR) model (without the TCI effect) are considered in
Introduction: Radiotherapy treatment planning is a multi-criteria problem. Any optimization of the process produces a set of mathematically optimal solutions. These optimal plans are considered mathematically equal, but they differ in terms of the trade-offs involved. Since the various objectives are conflicting, the choice of the best plan for treatment is dependent on the preferences of the radi
Similar to most countries, the Brazilian water resources management considers topographically delineated catchment as a territorial unit for policy implementation. Yet, previous studies have shown that catchments are not hydrologically isolated, and topographic limits often neglect the groundwater boundaries. Thus, studies on effective catchment areas are promising for shedding light on inter-catc
Bakgrund Truppgymnastik är en relativt ny och populär sport som ursprungligen kommer från Skandinavien. Sporten är indelad i tre delar; tumbling, trampett och fristående. Det är avancerade rutiner och kroppen utsätts för stora krafter vilket kan leda till ökad skaderisk. Vilken typ av skador som är vanligast, skadeincidensen och i vilka moment som skadorna uppkommer inom truppgymnastik är ett rela
The EU cohesion policy is a key policy area of the Union which aims for sustainable development and socioeconomic growth in the regions of the Member States. However, in the current structure of the multi-level governance system, the EU is much reliant on the capacity of the national public administrations to execute and implement the cohesion policy and thereby achieve the intended EU policy obje
Bus Rapid Transit (BRT) är en benämning på ett högkvalitativt kollektivtrafiksystem som utvecklades under mitten av 1900 – talet och blev känt efter att det framgångsrikt implementerades i staden Curitiba i Brasilien. I Sverige används BRT som ett komplement till övrig kollektivtrafik medan det i stora städer runt om i världen fungerar som stommen i kollektivtrafiksystemet. För BRT i Sverige finnsBus Rapid Transit (BRT) is a name for a high – quality public transport system that was developed in the middle of the 19th century and became known after it was successfully implemented in the city of Curitiba in Brazil. In Sweden, BRT is used as a complement to other public transport, while in large cities around the world it functions as the frame of the public transport system. For BRT in Swed
During an archaeological excavation in Uppåkra 2010 I found a so-called “guldgubbe”(goldfoilfigure). This find really caught my attention and especially so because their functions are still debated. This master thesis is about the meaning and use of this, more appropriately called, goldfoilfigure. Many attempts to solve the questions surrounding the functions of the figures have been made during t
Titel: Du sköna nya konsument - En kvalitativ studie om hur konsumenter resonerar kring virtuella recensioner.

Det relativt nya fenomenet reality-serier blir allt populärare och upptar en stor del av dagens tv-tablå. Fenomenet tillsammans med övrig massmedia har större inflytande och påverkan på samhället och oss människor än någonsin tidigare. Man diskuterar alkoholens roll i samhället, dess konsekvenser för relationer, hälsa o.s.v. Sedan TV kom har även alkoholens representation i TV kommit att bli en he
Trap roads are a part of the Swedish railway facility and resembles the safest front- and side protection at speed above 160 km/h. When designing Trap roads, some regulations needs to be followed. As these, in some cases, may be contradictory towards each other, the planners become somewhat insecure. The purpose of the master thesis has thenceforth been to clarify for the planners, as well as to w
Title: Drivande faktorer för individuell användning av big data system inom revisionsbolag Seminar date: 11/1-2023 Course: FEKH39, Degree Project, Business Administration, Undergraduate level, 15 University Credit Points ECTS Authors: Christoffer Yngwe, Jacob Svensson & Rasmus Thunberg Advisor: Magnus Johansson Keywords: Audit, big data systems, UTAUT-model, big data usage, general ledger syst
Schizophrenia is a disease highly characterized by a disturbed perception of reality, where delusions often generate misinterpretations of the individuals perceptions. Emotion processing has been widely documented within schizophrenia, which above all has demonstrated a reduction regarding the Theory of mind. Also well documented is that individuals with schizophrenia depict a reduced perceptual a
Bakgrund: Höga ljudnivåer och bullerskador är ett vanligt problem på arbetsplatser. Många väljer att inte använda hörselskydd då de upplevs försvåra kommunikation. En metod som med ett enkelt mått kan utvärdera hörselskydds påverkan av taluppfattning vore värdefullt. Syfte: Syftet med studien var att undersöka möjligheten att med metoden Speech intelligibility impact Level (SiimpL) mäta skillnad m
Earlier treatment of breast cancer results in better survival. Screening enables this through detection of tumors before they cause symptoms. On the negative side, some tumors if not detected through screening would not cause symptoms, leading to overdiagnosis. Improvements in image quality allow even earlier detection and diagnosis of even smaller tumors at an even earlier stage. This study aims
