The first neutron star-neutron star (NS-NS) merger was discovered on August 17, 2017 through gravitational waves (GW170817) and followed with electromagnetic observations. This merger was detected in an old elliptical galaxy with no recent star formation. We perform a suite of numerical calculations to understand the formation mechanism of this merger. We probe three leading formation mechanisms o

The volcanic island of Jan Mayen, located in the Norwegian – Greenland Sea, has very few lake basins out of which only one, Lake Nordlaguna, holds a permanent lake throughout the year. The island is volcanic and has been glaciated, but the lake basin is not genetically typical for volcanic crater lakes or other common types of volcanic lakes. Nor is it typical for ice-scoured glacial lakes. Instea

This is a narrative study about being in a relationship with a child cancer survivor. Previous research in the field of partnership and cancer has focused on experiences of being a partner to a person who is currently in cancer treatment. There is a lack of knowledge regarding partnership to a person who has gone through a cancer treatment prior to being in the relationship. More children who are

Den diplomatiska immuniteten har spelat en viktig roll inom den internationella rätten och det diplomatiska arbetet i världen under en mycket lång tid. Principen om beskickningslokalers okränkbarhet regleras i artikel 22 i Wienkonventionen om diplomatiska förbindelser och är enligt sin ordalydelse absolut. Bestämmelsen innebär att mottagarstaten är förbjuden att beträda lokalen utan beskickningschThe role of diplomatic immunity within international law is one of great importance. The principle of inviolability of mission premises is governed by Article 22 of the Vienna Convention on Diplomatic Relations and is in its wording absolute. The provision states that a recipient state is prohibited from entering the premises without the consent of the head of the mission. At the same time, the re

I maj 2019 antog regeringen EU:s direktiv om skydd för personer som rapporterar om överträdelser av unionsrätten, även kallat visselblåsardirektivet. Det konstaterades att den befintliga lagstiftningen, lag (2016:749) om särskilt skydd mot repressalier för arbetstagare som slår larm om allvarliga missförhållanden, inte levde upp till de minimikrav som fanns i direktivet. Därav fattade regeringen bIn May 2019 the government adopted the EU-directive on protection of persons who report breaches of Union law, also known as the whistleblowing directive. It was stated that current legislation, The act on special protection for employees who report on serious misconduct from 2016, did not fulfill the minimum requirements stated in the directive. Hence, the government made the decision to implemen

Amelogenin is a major constituent of enamel matrix protein that is responsible for the development of tooth enamel. Due to its self-assembly and physicochemical properties, amelogenin has been widely used as one of the natural biomaterials. Amelogenin, along with the other enamel matrix proteins have been known for its regenerative properties. The purpose of this project is to evaluate the enginee

We live in a time that some choose to call the psychedelic renaissance. Once again, after a period of silence in the scientific world, studies about psychedelics and their effects continues to bring knowledge to the subject. In this renaissance of psychedelics there’s still somewhat a gap in research regarding the recreational use of the substances. The aim of this study has been to seek a better

Introduktion Simuleringsmetoder är något som numera förekommer i en mängd olika sammanhang. De förekommer i olika former vid produktutveckling i industrin samt för att t ex studera komplexa system inom vetenskapen. Utöver detta förekommer det även i spel-och filmindustrin. I det stora hela handlar det om att skapa en förenklad dator-representation av verkligheten, så att man kan studera vissa föIn this thesis, an implementation of inline integration is described and examined. Inline integration is a mixed symbolic and numerical method for simulating fully implicit ordinary differential equations (DAE:s) whereby discretizations are introduced symbolically at model level. A generalized solution to the discretized model containing tailored iterative solving schemes and symbolic solutions is

Freezing is a method used to preserve food for long periods of time by reducing the rate of naturally occurring reactions and growth of microorganisms. However, some irreversible quality changes, both physical and chemical, can take place during the freezing step. After being frozen, the products are stored until thawed and consumed. This thesis studies innovative freezing technologies to understa

Examensarbete vittnar om bättre tider för njursjuka För få utförda kontroller av vattenkvalitet kan medföra livshotande tillstånd för njursjuka dialyspatienter. Ny teknik kan öka provtagningsfrekvensen och höja säkerheten. Den konstgjorda njuren Dialys är en behandling som syftar till att ersätta njurarnas funktion; att rena blodet från gifter och överflödig vätska. Vid hemodialys, även kallad bRenal diseases are an increasing problem worldwide and when kidney transplantation is not possible, dialysis treatment is the solution. An increasing number of patients choose to perform their dialysis treatment at home by implementing the dialysis machine and a water purification system in current electric and water supply, so called home hemodialysis. The quality of the water used for the prepar

Syftet med förevarande uppsats är att belysa den sakrättsliga problematiken kring lösöreköp genom att undersöka huruvida avtalsprincipen är förenad med tillräckligt stora fördelar för att ersätta den nu gällande traditionsprincipen. Traditionsprincipen har tillämpats i svensk rätt sedan 1800-talet. Dessförinnan erhöll en köpare skydd mot säljarens borgenärer genom köpeavtalet, i enlighet med avtaThe purpose of this essay is to throw light upon the complexity of the branch of law as regards the Swedish law of property and inquire whether the advantages of the doctrine of consensus exceed the benefits of maintaining the existing doctrine of traditio. The doctrine of traditio has existed in Swedish law since the 19th century. Before that, the buyer obtained protection against the seller’s cr

Geovisualiseringsverktyg är datamiljöer av geografiska data och presenterar vanligtvis kartor i antingen 2D eller 3D. Dessa kartor kan till exempel representera stadsmiljöer, vägnät eller vandringsleder. Geovisualiseringsverktygen blir kontinuerligt mer detaljerade och datadrivna. Samtidigt blir de också mer interaktiva. Det är till exempel möjligt att klicka på objekt, zooma in och ut, och lägga Geovisualization tools are continuously becoming more complex. These tools can present vivid and highly accurate representations of the real world. Simultaneously, spatial data is becoming incredibly detailed and the possibilities of interacting with the geovisualization tools are plentiful. Geovisualization tools are indeed powerful. However, in contrast to the well-developed technological side o

Du vaknar på morgonen kollar på din mobiltelefon om det hänt något nytt och spännande, tar datorn med dig till jobbet eller plugget och efter en lång dag sätter du dig i soffan och slår på Tvn. Alla dessa prylar har en central roll i vår vardag och är baserade på en gemensam nämnare som möjliggjort detta– transistorn. I din mobiltelefon finns det ungefär 200 miljarder av dem, i datorn ännu fler. TWith the transistor being the workhorse in modern electronics it has been vastly improved since its invention. However, the previous go-to improvement method of scaling it down has reached a dead end. Power dissipation has become a large concern and is in need of a solution. In the pursuit of further improving the transistor structure and its performance new approaches are being evaluated. A very

Under första delen av 1900-talet ägde ett normskifte rum i den juridiska världen. Uppsatsen belyser den kvinnliga kampen för högre juridiska utbildningar och befattningar. Denna kamp har varit utdragen, och kvinnornas rättigheter har inte varit självklara. Syftet med uppsatsen är att undersöka varför det tog så lång tid för kvinnorna att få rättigheterna till högre juridiska utbildningar och tjänsDuring the first part of the 20th century a norm change took place in the legal world. The thesis highlights the female struggle for higher legal education and positions. This struggle has been long, and women’s rights have not been self-evident. The aim of the thesis is to analyse why it took so long for women to gain the rights to higher legal education and positions and why Akademiskt bildade k

Idag säljs annonsplatser på hemsidor i allt större utsträckning via realtidsauktioner. Ofta tar det mindre än 100 millisekunder att auktionera ut en annonsplats från det att en användare besöker en hemsida.

This has spurred a research interest into how to design optimal bidding algorithms, with advances during the last two to three years focusing heavily on reinforcement learning. This thesis focuses on creating bidding agent using recent innovations in combining reinforcement learning and deep lear

With the ongoing climate collapse, there is a need for a capital switch, rerouting investments into low carbon infrastructure. Green bonds are a new financial vehicle aimed to facilitate this transition. Through signaling the issuers’ intent to use the proceeds of the bonds towards environmentally beneficial activities, they increase transparency and allow investors to better calculate risks while

Carbonatite is an unusual type of rock that, for a long time, were not accepted for what they really are. This group of rocks is now considered to be of igneous origin and is classified after its content of carbonate minerals. If it exceed 50% the rock will be named a carbonatite. This group of rocks can be found all over the world and two of these places, which this review will focus on, are the
