The main topic of this thesis is the storage location assignment problem, which can also be seen as a traveling salesman problem. The objective is to find the shortest path between items to be picked at a medium-sized warehouse. Orders come in batches consisting of items that will be assembled in-house. Therefore, it is essential to pick up all the items contained in the batch before they are drop

This essay is written with the intention to analyze in what way Nils Liljas published works Menniskan och Kärleken, can be seen as works with the intention to popularize science. What language and linguistic techniques he use in his texts will be examined, to motivate the thesis that he wrote these to reach out to a bigger crowd, than that of the academic circles in the society. With a theoretical

Adult neurogenesis is the process of generating new neurons from neural stem cells (NSCs) in the adult mammalian brain, which occurs in two neurogenic niches; the subventricular zone (SVZ) of the lateral ventricles and the subgranular zone (SGZ) of the hippocampal dental gyrus (DG). In rodents, neurogenesis continues throughout life, but this process decreases with age, which may result in cogniti

Flyktingar löper signifikant högre risk för att utveckla psykisk ohälsa, däribland posttraumatiskt stressyndrom (PTSD). Det finns en stor evidensbas som visar att traumafokuserade psykologiska behandlingar för PTSD är effektiva. Majoriteten av denna forskning inkluderar dock inte flyktingar, vilket innebär att mindre är känt om responsen för behandling av PTSD hos flyktingar. Den aktuella översiktRefugees are at significantly increased risk of mental health difficulties, including Post-Traumatic Stress Disorder (PTSD). There is a large evidence base showing that trauma-focused psychological treatments for PTSD are effective. However, the majority of trials do not include refugees and less is known about response to PTSD treatments in refugees. The present scoping review explores the curren

Klimatförändringar är en av vår tids stora utmaningar. För att kunna möta dessa finns det ett brådskande behov av att minska vart stora beroende av fossila bränslen. En lovande råvara för produktion av förnyelsebara och koldioxidneutrala bränslen är bioolja. Bioolja kan användas som ett substitut för råolja i raffinaderier och produceras från biomassa, vilket innebär att den kan agera som ett förnTo be able to face the challenges brought on by climate change there is an urgent need to reduce the heavy dependence on fossil fuels. Bio-oil is one such renewable and carbon-neutral replacement that has shown promising potential. A key step in making bio-oil commercially feasible is improvements of the upgrading processes of the bio-oil. One such upgrading process is catalytic hydrodeoxygenation

This is a project about local small scale production, a story about how an artisan designer could take on the IKEAs of the world armed with modern day technology and some old fashioned hard work. This project is at its core a reflection about the future of design general and my role in particular. This contemplative journey does a few stops along the way to discuss the following sentence and wh

Phylogenetic tree analysis is a powerful method for studying the evolution of gene families. There are many different software available to produce and annotation phylogenetic trees that vary in their ease-of-use and user autonomy. We developed a new pipeline tool Easy Protein Tree Annotating (EPTA) to provide a user-friendly tool for phylogenetic tree generation and annotation. EPTA is a command-

Som ett resultat av den ökade gängkriminaliteten i Sverige, infördes den 22 juli 2022, ett kronvittnessystem som blivit enormt kritiserat från många håll. Lagstiftaren ansåg det dock vara övervägande nödvändigt med denna reglering, som framförallt avsåg införandet av 29 kap. 5 a § Brottsbalken. Lagändringen kan beskrivas som ett försök att komma ur den rådande tystnadskulturen och initiera en effeAs a result of the increased gang violence in Sweden, a crown witness system was introduced on July 22, 2022, which has been widely criticized. However, the legislator considered such regulation to be predominantly necessary. By introducing a new paragraph, ch. 29 § 5 a in the Swedish Criminal Code, the legislation can be described as an attempt to escape the culture of silence and initiate an eff

Wildfires are increasing in frequency and severity, and the media often uses metaphors to describe and dramatize these events. Metaphors are a key part of how society communicates and can strongly influence perception. This thesis aimed to analyze the use of metaphors by the Swedish news media when reporting on wildfires and to examine whether the use of metaphors affect public perception of the s

Under de senaste 30 åren har en ny metod för att få information om tidigare ekosystem utveck- lats, nämligen att analysera gammalt (“ancient”) DNA (aDNA). Denna forskningsgren är fortfarande ung men har redan hittat många områden inom vilka den kan tillämpas. Inom paleoekologin finns det två huvudsakliga ändamål med aDNA-analyser; att kartlägga en arts hela genom, samt att bestämma antal taxa och During the last 30 years a new method for obtaining information about past ecosystems has been devel- oped, namely to analyse old (“ancient”) DNA (aDNA). This research field is still young but has already found many areas within which it can be applied. In palaeoecology, there are two main purposes with aDNA analyses; to map the entire genome of a species, and to determine the number of taxa, and

The goal of this project was to examine whether there are correlations between recent wildfires in the northern hemisphere and stratospheric ozone anomalies in the midlatitudes following the creation of ozone depleting substances. To achieve this goal, data from the Aura satellite's Microwave Limb Sounder instrument was used and processed with self-written Python scripts. Firstly, in order t

Rapid global urbanization is a major concern for the food production system, as it is recognized that relying on conventional methods of distant large-scale farming contributes significantly to greenhouse gas emissions. One of the key strategies to address this challenge is rooftop greenhouses (RTG), which are greenhouses built on unoccupied rooftops. Besides that, this technology goes beyond crop

Populärvetenskaplig sammanfattning Vid kemiska analyser på laboratorium är det ofta nödvändigt att separera olika molekyler i en blandning med hjälp av vätskekromatografi. Vätskekromatografi är en separationsmetod där man använder sig av tvåfassystem. Masspektrometri är en teknik där joner separeras i gasfas baserat på deras massa i förhållande till laddning (m/z). En kombination utav dessa metoAbstract Introduction: this study is about optimization and application of a new liquid chromatography tandem mass spectrometry method with reversed phase instead of HILIC column for analysis of methylmalonate. Background: methylmalonate cannot be broken down if there is a low level of cobalamin. Therefore, the investigation of lack of cobalamin is supplemented with, among other things, methyl

Ever since the Great Recession in 2008, the effectiveness of monetary policy has been increasingly debated. Central banks in modern economies were forced to find new ways of conducting expansionary monetary policy beyond conventional methods, most notably through quantitative easing and forward guidance, as they were at, or very close to, the zero lower bound of nominal interest rates. However, ev

In an evermore competitive environment for companies and business, predictive customer behaviour models can give companies a competitive edge over its competitors. Two such important predictive behaviour models are customer churn models and customer lifetime value (CLV) models. As it is more expensive for companies to acquire new customers rather than retaining existing ones, it is important for b

The recent revolution in structural prediction methods has made modeling novel protein structures a feasible analysis method. In particular, the Alphafold protocol can produce accurate models with atomic resolution. This work aims to model multiple novel toxin-antitoxin systems and to understand the interactions of their components through structural prediction and interface analysis. Structural p

Recruitment of new individuals is essential for a population to survive and flourish and bladderwrack (Fucus vesiculosus) is on the decline in some parts of the Baltic Sea. The causes being multitude and complex, culminating to the loss of light penetration being the main culprit. As society moves forward, artificial submerged structures may serve as new footholds for a waning population as well a

Disposable hygiene products, such as gloves and aprons, are commonly and frequently used in healthcare environments and are essential to maintain the hygiene standard. They are placed in different types of carriers, primarily in examination rooms and are mounted on the walls. This creates some difficulties for product development and fast access because not all hygiene products fit all carriers an
