The production of plastics has seen incredible growth in recent years. Accordingly, the release of plastic particles (micro and nano) into the environment is also increasing. Information on environmental, biological concentrations, and the fate of nanoplastic (NP) in aquatic environments are scarce. Most in vitro studies have been investigating the effects of NPs at higher exposure concentrations
Med ökad andel intermittent elproduktion i Sveriges elproduktionsmix och ett åldrande stamnät ökar behovet av flexibilitet i elsystemet. Lagring av energi, till exempel i vätgas, är ett exempel på en sådan flexibilitetslösning, eftersom energin kan flyttas från tidpunkter med överskott till tidpunkter med högt energibehov. Syftet med examensarbetet är att undersöka energisystemnyttan med ett v ägaSweden’s increasing share of intermittent electricity production and aging backbone network has given rise to a need for flexibility in the energy system. A potential solution to this challenge is energy storage, where hydrogen is a possible pathway. This master’s thesis aims to investigate the energy system benefits of a hydrogen system for seasonal energy storage of excess solar electricity in a
Due to the steep requirements of the 1.5°C goal, there is an urgent need to better understand what measures can be used to strengthen climate mitigation efforts. This study illuminates which factors drive climate mitigation efforts in the Swedish public and how such efforts are affected by new information. Using data gathered in an online survey experiment (n=372), this study finds that a wide ran
Topology optimization is a method used to find optimal material distributions, within a specified domain, with respect to some performance measure. To avoid various artifacts to appear in the suggested design, the solution space is typically restricted, where some restriction methods allow different length scales to be controlled in the design. The suggested material distribution may result in com

I tre somrar har jag jobbat på ett sommarkollo för barn. Under min tid där utvecklades tankar om hur dagens kolloverksamhet hade kunnat stöttas av förändringar i stugornas utformning. Detta ledde till mitt val att göra ett examensarbete med syftet att gestalta en nutida kollostuga. Kollo som verksamhet har krympt sedan 1950-talet då det var som störst. Under den senaste tiden har efterfrågan vuxiThree summers I’ve worked at a summer camp for children. During my time there I started to think about how today’s summer camp could benefit from changes in the buildings appearance. This led to the decision that my thesis project will be to design a building for a summer camp of today. The summer camp movement in Sweden have increased since the 50’s when it was as its greatest. In recent times th
Syfte: Studien syftar till att undersöka om informationsasymmetri driver underprissättning inom techbranschen på handelsplatsen Nasdaq Stockholm, mellan tidsintervallet 2017.01.01 till 2021.09.30. Metod: Studien har genomförts utifrån en deduktiv ansats där kvantitativa forskningsmetoder har tillämpats. Under studiens gång har sekundärdata i form av börsnoteringar samlats in. Därefter undersöks
This paper aims to investigate two questions. Firstly, does correct salary information affect the probability of becoming a nurse? Secondly, are individuals affected by a halo effect when determining social status for nurses? I conducted an online experiment with 124 participants from the Department of Economics in Lund and Hedda Andersson High School in Lund. Respondents were treated with informa
Organisationer finns i otaliga mängder, former och av olika anledningar. Något som fått stor uppmärksamhet i denna kontext är ekonomistyrning och utformningen av denna. Ett skifte har under senare år skett från att tidigare styra med järnhandskar till att numera lägga större vikt vid laganda och självgående arbetare. Till följd av den uppmärksamhet som detta fenomen har ådragit sig så har flerOrganizations exist in countless sizes, shapes and for different purposes. This fact has contributed to an increase in the attention to management control systems and the design and implementation of the very same. There has been a shift in recent years, from ruling companies with an iron fist to promoting team spirit and self sufficient workers. Due to the increase in attention there has also
Supply Chain Management inside the Cell Factory Climate change and environmental sustainability goals decades ago led to an examination of bio-based solutions as possible alternatives to using fossil fuels. The use of modern genetic engineering and gene swapping between organisms allow modern microbiologists to create bespoke organisms that operate as cell factories, the most well-known of which
COVID-19 - hur kan celler från fostervatten vara till hjälp? Sedan slutet på 2019, då COVID-19-pandemin bröt ut i Wuhan, Kina, har forskare världen över letat efter sätt att hjälpa folk som insjuknat av viruset. Mesenkymala stamceller, en typ av stamceller som kan utvinnas från ett flertal ställen i vår kropp, bland annat fostervatten, har stora möjligheter till att kunna hjälpa de människor som
Bästa att var blå eller brun fjärilshona? Solen skiner och fjärilarna cirkulerar runt bland dina blommor. Har du någon gång funderat på varför fjärilar ofta är så färgrika? Här i Sverige har vi ca 400 dagfjärilar och en av de allra vanligaste är en liten men färgglad vid namn puktörneblåvinge (Polyommatus icarus). Hannarna är ljusblå med en stilren svart konturlinje och honorna varierar mellan atButterfly wing coloration and pattern are believed to be shaped by selection pressures arising from the needs of thermoregulation, as signals to conspecifics, or reducing predation risk. The Common Blue Butterfly (Polyommatus icarus) display a large variation in dorsal wing blueness among females. The gradual pattern of brown to blue wings varies between individual females and among populations in
Personality tests are a common tool in recruitment. A problem that may arise is candidates who adjust their answers in a socially desirable way to improve their chances of employment. The research question of this study was: “How the reporting of personality traits is affected by manipulation of the content of a fictional job advertisement and can this be interpreted as socially desirable respondi
The purpose of this thesis is to examine the document “Hur kan det vara så här?” made by Swedish minority journalists on Sveriges television. The document was composed to shed light on how the journalists perceive the newsroom culture on the Swedish public service television company from their minority point of view. The question that the journalists raise is interesting, as SVT as the public serv
Forest fires in mainland Portugal are becoming more extreme, resulting in increasingly larger burnt areas and tragic human fatalities, as was shown by the 2017 fires. Research shows that there are many natural factors contributing to such fire vulnerability conditions, such as climate, fuel continuity, forest structure, tree species types, amongst others, that are intertwined with anthropic factor
Under de senaste åren, har system vars dynamik sker ur jämvikt fått mycket uppmärksamhet, främst på grund av stora framsteg inom experimentella förverkliganden inom nanosystem som kan utnyttja kvanteffekter, och experimentella verktyg som tillåter mätningar under väldigt korta tidsfönster. I dagens samhälle där vi använder datorer och nanochip, praktiskt taget, överallt är det viktigt att förstå sIn this thesis we employ the non-equilibrium Green’s function (NEGF) method to study both finite and infinite systems. We develop a codebase capable of computing the steady state interacting NEGF in open systems, i.e. tight-binding leads contacting a central region, in both Hartree-Fock (HF) and second Born (2B) approximations of particle-particle interactions. Furthermore, we use the exact intera
