Allting är uppbyggt av atomer, inte bara träd, djur eller bläcket i dessa bokstäver, utan även astronomiska objekt så som stjärnor och planeter. Stjärnor är i princip extremt varma och kompakta moln av atomer, som skickar ut ljus i alla riktningar. Astronomer är intresserade av vilken sammansättning av atomer som bygger upp stjärnor eftersom detta hjälper dem att förstå hur stjärnor och galaxer biStellar abundances are important for understanding the chemical evolution of galaxies and provide us with constraints on stellar evolution and supernova nucleosynthesis. To determine stellar abundances accurately, atomic data is crucial. This data is incomplete for many elements, especially in the infrared region. In particular, hyperfine structure (hfs) data in the near-infrared region is lacking

Highly glazed spaces are continuously increasing in popularity due to architectural attractiveness. However, increased use of glass often jeopardizes thermal comfort in several ways and problem of overheating is one of them. A way to face this problem is to appropriately use solar control mechanisms. However, a proper selection of solar control mechanisms from an early design stage is a complex ta

Vid marktekniska undersökningar i finkorniga jordar är det av stor vikt att korrekt kunna bestämma den odränerade skjuvhållfastheten. Detta görs idag vanligtvis ute i fält med en uppsjö av sonderingsmetoder som ger olika mått på hur fast jorden är. För homogena leror och sand finns det en stadig empirisk grund för hur dessa sonderingsparametrar räknas om till odränerad skjuvhållfasthet, men hur seThe undrained shear strength is a key parameter in the design process of geotechnical structures. One of the most frequently used methods to investigate this parameter is the cone penetration test (CPT). The CPT does not measure the undrained shear strength directly, but instead the resistance that a conic probe encounters as it is pushed into the ground. A calibration factor, the cone factor (Nkt

Två studenter, Safa och Jane, från kemiteknikprogrammet LTH har undersökt möjligheten att hantera hela reningsprocessen av spillvatten på Dow Chemical site i Landskrona genom att installera en pilotanläggning för nanofiltrering i anslutning till den redan befintliga ultrafiltreringsanläggningen. Dow i Landskrona framställer olika vattenbaserade bindemedel från akrylmonomerer och stora mängder vatDuring the spring semester 2018, an investigation about supplementary cleaning of the waste water at Dow Chemical site in Landskrona was done. Different water-based binders from acrylic monomers are produced by Dow and large amounts of water is used for such processes. The wastewater, that is treated currently by ultrafiltration (UF), contains different chemical residues such as surfactants, resid

The aim of this research is to study three particle correlations in pseudo-rapidity for the $\Lambda^0$,$\Xi^0$, and $\Omega^-$ hyperons with a focus on their baryon and strangeness quantum numbers. The two primary questions asked are, into which particles are these quantum numbers typically conserved, and what are their correlations in momentum space. The research investigates these problems by e

Sperm whales (Physeter macrocephalus) communicate with one another using an intricate language made up of sequences of clicks. Recent studies have begun to dig deeper into the structure and content of these vocalisations in an effort to detect and extract significant patterns and features. Whether or not the results of such research will eventually allow us to translate sperm whale speech into som

Den 1 juli 2022 trädde en ändring av lagen (1988:254) om förbud beträffande knivar och andra farliga föremål, även kallad knivlagen, i kraft. Denna innebar bl.a. att kvalifikationsgrunder infördes för bedömningen av om ett brott ska rubriceras som grovt, och att straffskalan för grovt brott skärptes till fängelse i lägst sex månader och högst två år. Syftet med den här uppsatsen är att analyseraOn 1 July 2022, the Swedish Act (1988:254) on the Prohibition of Knives and Other Dangerous Objects (the Swedish Knife Act), which criminalizes possession of knives and other dangerous objects in public places, was amended. Through the amendment, four criteria were introduced to the statutory text, which are to be given particular consideration when assessing whether a violation of the law is to b

Sustainability reporting remains a well-established field of research, with many important contributions. Additionally, the public has a growing desire for firms to adopt responsible ESG practices, thus requiring more transparency and accountability. Without the acceptance from the public, the business might face negative consequences. The understanding of how sustainability reporting is disclosed

The aviation industry continues today to be one of the main sources of green house gas emission. In order to counteract this trend, certain solutions are being invested in with one of these being the use of electro-based sustainable aviation fuels. Its drop-in ability and potential for reduction in emissions present eSAF as one of the most attractive and viable alternatives to decarbonisation of t

A great amount of financial statements of Swedish companies are registered with the Swedish companies registration office, Bolagsverket, as paper copies. These copies are then scanned and made available to the public as image-PDFs, meaning the financial information contained in them is not digitised and therefore not easily processed in an automated manner. Being able to do so, is valuable however

Problem Statement: Company Pie is planning for a new centralised distribution centre, as part of a reorganisation of their distribution network. This entails consolidating volumes from several existing facilities, and another company named Company Rho, when setting up a distribution centre configuration. Company Pie wants a second set of eyes to create a configuration, including operations, and de

5G NR är den senaste generationen mobilnät och är efterföljaren till Fourth Generation (4G) Long-Term Evolution Advanced (LTE-A). I mobilnäten kan användare koppla upp sig mot basstationer med sina enheter som kan vara en mobiltelefon eller dator. Basstationerna består av antenner som kan både skicka och ta emot information samt en radioenhet som hanterar trafik till och från stationen. Eftersom aAs the latest generation of wireless access technology called Fifth Generation (5G) New Radio (NR) evolves, computational efficiency is key to keep low cost and flexible deployments for vendors. Understanding how the Digital Signal Processing (DSP) load behaves in the digital units is one aspect to enable this efficiency. This thesis investigates how the DSP load in the base station behaves for a

I svensk rätt tillämpas asperationsprincipen vid straffvärdebedömning av flerfaldig brottslighet. Vid flerfaldig brottslighet ska ett gemensamt straffvärde bestämmas och domstolen utgår från det allvarligaste brottets straffvärde och de övriga gärningarnas straffvärden reduceras i en fallande skala. Detta system har mött kritik i form av att påföljderna vid flerfaldig brottslighet blir för milda iIn Swedish law, the principle of asperation is applied when estimating the penal value for multiple offences. In the case of multiple offences, a common penal value is determined and the court starts from the most serious offence, with the penal value of the other offences being reduced on a descending scale. This system has been criticized for making penalties for multiple offences too lenient in

I samband med framarbetandet av 36 § avtalslagen uttrycktes olika uppfattningar vad beträffar hur domstolarnas avgöranden bäst bör utformas för att främja vägledning och förutsägbarhet i en annars obestämd generalklausul. Principiellt med möjlighet att stämpla villkor som oskäliga i sig framfördes i lagmotiven. Kausistiskt, baserat på omständigheterna i det enskilda fallet, menade flertalet remissIn connection with the preparation of section 36 of the Swedish Contracts Act, different views were expressed as to how the courts' decisions should best be formulated in order to promote guidance and hence predictability in an otherwise indefinite general clause. Principally designed with the possibility of stamping contract terms as unreasonable in itself, it was argued in the law motives. B

Building Information Modelling (BIM) is arising gradually as a useful methodology in the AEC field. One of the many benefits of BIM is coordination between stakeholders from multiple disciplines. However, the field of Fire Safety Engineering (FSE) is relatively lagging by its lack of integration into this digital workflow. This lack of integration increases the efforts needed to evaluate the desig

Under det senaste decenniet har rättsstatens ställning som ett värde av grundläggande vikt för EU-rätten ifrågasatts genom den politiska utvecklingen i vissa medlemsstater. Särskilt i Polen och Ungern går det att se hur centraladelar av statsmakten har nedmonterats. År 2021 införde EU en villkorlighetsmekanism, som ger EU:s institutioner befogenhet att hålla inne budgetåtaganden till medlemsländer

Sverige är en rättsstat som bygger på många olika principer för att kunna för-säkra ett fungerade rättsväsende. En viktig sådan är principen om domens orubblighet. De domar som en domstol meddelar ska stå fast när dessa vunnit laga kraft, vilket kallas för en doms negativa rättskraft. Vidare har de mänsk-liga rättigheterna som inkorporerats i svensk lagstiftning genom EKMR en stor plats vid lagstiSweden is a state governed by the rule of law, and is based on many different principles in order to ensure a functioning justice system. An important prin-ciple is that the rulings from the courts should be adamant, also known as the principle of firmness. The ruling of the court shall stand when it has gained legal force and this is also known as the negative legal force of a judgment. The human

BIM, byggnadsinformationsmodellering, är ett arbetssätt som blir allt vanligare. Det innebär att olika objekt bygger upp en övergripande 3D-modell där man kan finna mängder av information om dessa objekt. Ett objekt kan vara allt ifrån en bropelare till en elstolpe. Syftet med denna rapport är att utifrån Trafikverkets roll som beställare undersöka vilka för- och nackdelar det skulle innebära med BIM, Building Information Modeling, is an increasingly common way of working. This means that different objects build up an overall 3D-model where you can find lots of information about these objects. An object can be anything from a bridge pillar to an electric pole. The purpose of this report is to, based on the Swedish Transport Administrations’ as a client, investigate the advantages and disad

Introduction: This study attempts to optimize the choice of stationary phase for the separation of lignosulfonate lignin compounds using supercritical fluid chromatography coupled to mass spectrometry. Background: Lignin is a potential renewable source of phenolic compounds. Lignosulfonate lignins are produced during pulping processes producing very complex mixtures, which are challenging to anal

Coffee production systems are experiencing climate change stress in a multitude of ways. One of the ways in which climate change manifests itself in coffee systems is through the evolution of pest and disease populations. Global coffee production is thereby recognized as vulnerable to climate change, particularly the lives of those that rely on coffee for their livelihoods. Reducing vulnerability
