Parkslide: en ”mardrömsväxt” i Skåne Invasiva arter är en av de största direkta hoten mot biodiversitet. De kan också hota ekosystemtjänster, och till och med människors hälsa. Invasiva arter beräknas kosta EU och Sverige flera miljarder kronor per år. Antalet invasiva arter i Sverige ökar, och global uppvärmning förväntas göra problemet värre. Den allra största gruppen av invasiva arter är landvInvasive alien species (IAS) are one of the most important direct drivers of biodiversity loss and changes in ecosystem services. Over the last 20 years IAS are estimated to have cost the EU at least 12 billion euro per year. These costs continue to increase. Many IAS are expanding their territory, and thus both the current as well as future threat they pose must be taken into account. There is cu

Hur kan vi minska klimatpåverkan vid nyproduktion av småhus? Majoriteten av de aktivitet vi människor sysslar med genererar utsläpp av växthusgaser, växthusgaser som i sin tur skyndar på jordens växthuseffekt och leder till klimatförändringar. För många människor är en viktig del av livet att bygga bo, enligt boverket kommer det byggas ungefär 10 500 nya småhus i Sverige år 2020. För att kommandIn 2017, Sweden adopted a climate policy framework consisting of a climate law, climate objectives and a climate policy council. The target outcome for Swedish greenhouse gas emissions is determined to have no net emissions by 2045. The purpose of the thesis is to investigate which parts in a production of a new small scale house have the most climate impact, what measures can be taken to reduce t

The separator is a machine with many applications, commonly used to separate liquids or solids into components with different density. Each application demands its own unique set of process parameters to achieve optimal results. Often the procedure of finding the best process parameters is conducted empirically, which can be very time consuming. This thesis aims to address this problem by providin

Beräkningsmodeller som tar hänsyn till blodkärl i benet kan bättre förebygga höftfrakturer Du känner säkerligen till någon som råkat ut för en höftfraktur. Höftfrakturer är en typ av fraktur som drabbar många äldre med benskörhet och bidrar till mycket smärta och lidande. Tidig diagnostisering är avgörande för att kunna ge preventiv behandling och förhindra frakturer. En ny diagnostiseringsmetod Hip fractures are widely spread in today's society and affect a person's quality of life. Osteoporosis is a bone disease that results in more fragile bones and an increased risk of bone fractures, including hip fractures. A method proposed for assessing the fracture risk is finite element (FE) models of the femur. These FE models proved to be effective in predicting the overall mechanical

This paper examines the creation of safer spaces and discourse around exclusion among four feminist organizations that practice separatism. With the aim to make visible how boundaries are drawn and negotiated and how (un)safety is understood in this process, I conduct in-depth interviews with activists from these organizations. The theoretical framework draws upon Laclau and Mouffe’s theory on dis

Lipases in the Endocannabinoid System The endocannabinoid system (ECS) is found in the central nervous system (CNS) and includes the cannabinoid receptors CB1 and CB2 [the ‘locks’], the endogenous ligands anandamide (AEA) and 2-arachidonoylglycerol (2-AG)[the ‘keys’], and the enzymes (‘locksmiths’) that make and break down these ‘keys’. Activation of the CB1 and CB2 receptors by the endocannabino

Marknadsföringen av dagens charterresor och framväxten av postkolonial teori står under en diskursiv diskrepans. Därför syftar denna studie till att utifrån postkoloniala perspektiv analysera diskurser i aktuell svensk marknadsföring och klargöra för om turisters kulturella resurser kan ha grunden i koloniala privilegier. Med utgångspunkt i att företagen har egenintresse av att marknadsföringen spThe practise of marketing charter travels can today be seen as standing under a discursive discrepancy with the emergence of postcolonial theory. With a postcolonial viewpoint, this essay therefore aims to study marketing discourses in a Swedish context in order to understand the cultural resources Swedish consumers of charter tourism take part of. The costumer’s expectation of that marketing give

Understanding Oat with Artificial Intelligence Eating or drinking oat is considered healthy for you and the planet, but there is still much scientists don’t know about oat. One of the things they would really like to know is how exactly oat stores its molecules and how the structure of oat is related to that. One way to do this is by scanning oats with CT (a bit like a brain scan in the hospital)

Ett nytt sätt att skapa modellhjärnor i labbet När man bedriver forskning på celler i ett labb, så är det viktigt att cellerna faktiskt beter sig som de gör i kroppen. Labbmiljön för celler, är däremot oftast ganska långt ifrån den miljön de normalt upplever i din kropp, vilket har gett upphov till idén om 3-dimenstionella cellodlingar. 3D-Odlingar är idag förhållandevis utbrett, med ett brett ar

The baker’s yeast, Saccharomyces cerevisiae (S. cerevisiae) was studied and genetically engineered. This was to enhance the transamination step of the biochemical reaction cascade towards the production of capsaicin. Inherent reductases were identified and twelve of them knocked out via homologous recombination. Using the CRISPR/Cas9 technology, the Green Fluorescence Protein (GFP) gene was introd

Jordbruksmarken i Sverige är en stor anledning till varför en stor mängd kväve och fosfor transporteras till vattendrag, sjöar och hav. Näringstransporten medför konsekvenser för miljön då växtorganismers förutsättningar förändras och övergödning sker. Våtmarker är ett naturligt inslag i miljön som har näringsrenande egenskaper gällande kväve och fosfor. Under det senaste seklet har uppemot en fjäThe agricultural land in Sweden is a major reason why a large amount of nitrogen and phosphorus is transported to rivers, lakes and the sea. Nutrient transport has consequences for the environment as the conditions for plant organisms change and eutrophication takes place. Wetlands are a natural part of the environment that have nutrient removing properties regarding nitrogen and phosphorus. Durin

Title: Critical Supply Chain Factors for Scaling a Startup -- A Case Study in the Industry of Semiconductors Author: Pontus Landgren Supervisors: Bertil Nilsson, Lund University, Faculty of Engineering & Lennart Moberg, Acconeer AB Background: A well implemented supply chain strategy aligned with the company's overall strategy is a prerequisite in order to successfully scale a startup.

Obtaining DNA sequences is a time-consuming task, which typically requires one or several days for completion. One way of reducing analysis times is to be satisfied with long-range sequence patterns on the order of thousands of base pairs. DNA barcoding is a DNA-characterising technique that works according to this principle. It does so by using fluorescence microscopy to visualise long-range sequ

To optimize the weights in an artificial neural network most methods rely gradients, which are not always obtainable or desirable. Evolutionary algorithms are instead based on Darwinian evolution where no derivative is needed. These algorithms have a set of strategy parameters that can be dynamically updated during the search to increase performance. Two ways of updating the parameters are the so

Purpose: The purpose of this essay is to examine the different relationships between the auditor and its clients and how this relationships affects the quality of the audit. Theoretical perspectives: The theoretical framework is based on a description of relationships based on Duff (2014) and a description of audit quality which is partly based on Tepalagul & Lin (2015) and Wright & Wrigh

Due to a warming climate, tundra ecosystems are subject to shrub and treeline expansions which could lead to increased above- but decreased belowground carbon (C) stocks. An observed low soil C stock in some subarctic forests and tall shrublands has been suggested to be induced by priming of organic matter decomposition, possibly mediated by ectomycorrhizal fungi. On the other hand, the higher bel

I en jämförelse mellan det skriftliga och det arkeologiska materialet framträder en bild av medeltida tegelbruk i allmänhet och det medeltida tegelbruket vid S:t Mikael i synnerhet. Arkeologiskt iakttagbara anläggningar vid ett medeltida tegelbruk, förutom en tegelugn är följande; lertag i form av gropar eller stora gravar (eventuellt vattenfyllda), vallar efter leran som lagts till vintring, gropWhen, why and how the brick-making tradition started in the Nordic countries is well known. However, research on the spatiality and layout of the the production of bricks in medieval times is lacking. What archaeologically observable sites, apart from a kiln, were part of a medieval brickyard and how were they organized? In a comparison between written material on brick production and archaeologic

We unify literature on licensing in the pharmaceutical industry and empirically verify pre-established and identify new determinants of value creation and appropriation based on a contemporary data set of licensing deals made between 2015 and 2020. We observe positive returns for licensor and licensee. A return differential indicates value appropriation by the licensor due to scarcity. A positive

Respiratory tract infections (RTIs) are a major global health concern. Several studies indicate that most respiratory bacterial pathogens are capable of asymptomatic colonization and find their primary ecological niche within the nasopharynx of healthy individuals as harmless commensals that form biofilms. However, in response to external factors, such as concomitant virus infections, colonizing b
