Inducerar kemiska föroreningar antibiotikaresistens?

Kan kemiska föroreningar leda till ökad resistens hos bakterier? I dagens samhälle kan de flesta känna en trygghet kring utvecklingen av moderna mediciner som gör att allt fler sjukdomar kan botas jämfört med innan. Varje år kan det kännas som att mänskligheten gör framsteg vad gäller den medicinska utvecklingen. Dock är det inte så att det bara görs framsteg kring läkemedel utan vissa läkemedel kAntibiotic resistance is currently a very serious and pressing issue. Grave consequences are predicted in the future if the rate of resistance development continues as today. In relation to this there are many contaminants in our environment and the grade of effects of these contaminants on antibiotic resistance is still very much unknown. The aim of this study is to give an overview on this subje

Försiktighetsregeln i ABL - En undersökning av värdeöverföringarnas svårtillämpade generalklausul

En av de karakteristiska egenskaperna i ett aktiebolag är att aktieägarna inte bär ett personligt ansvar. Ett undantag från detta är ansvaret vid olovliga vär-deöverföringar. En värdeöverföring kan anses vara olovlig enligt försiktig-hetsregeln. Försiktighetsregeln är en central regel i det aktiebolagsrättsliga kapitalskyddet. Regeln kan ses som en generalklausul för värdeöverföringars lovlighet. One of the characteristics of a limited liability company (Sw: aktiebolag) is that the shareholders are not personally liable. An exception to this is the lia-bility for unauthorized transfer of value (Sw: värdeöverföring). A transfer of value can be considered unauthorized under the precautionary rule (Sw: försiktighetsregeln). The rule is an important rule in the capital protection of limited li

Metod: En kvalitativ ansats användes för att besvara syftet, för att få med individ

Video-based assessment of cyclist-tram track interactions in wet road conditions

Cyclist underreporting of lower severity and single cyclist collisions to police results in the underestimation of the societal costs of lower severity and single cyclist collisions. Prevention strategies for these types of collisions are becoming a popular area of research, and video-based approaches have obvious potential for these cases, allowing for detailed analyses of underreported lower sev

Interdisciplinarity and Lifelong Learning in Doctoral Education for Sustainable Development: A Case Study on the Agenda 2030 Graduate School at Lund University

The 17 UN Sustainable Development Goals (SDGs) provide a framework for “peace and prosperity for people and the planet, now and into the future” (UN, 2015). Fast-moving societal questions as the ones related to the SDGs are often addressed from within traditional disciplinary research paradigms, which might not be best equipped for tackling the emerging challenges.

Personalisation and Performed Authenticity in Political Content on TikTok: A Multimodal Critical Discourse Analysis of Liberal Alliance's Campaign in the 2022 Danish General Election

This research analyses the presence of political personalisation and its role in establishing performed authenticity in political content on TikTok. Despite TikTok being a platform created for entertainment purposes, TikTok has come to play a significant role in political discourse and engagement with politicians Employing a qualitative approach to Multimodal Critical Discourse Analysis, this rese

How Has the Current Electricity Crisis in South Africa Affected the Development of Renewable Energy within the Independent Power Producer Procurement Programmes?

This thesis examines the effects of South Africa’s electricity crisis on the government-driven development of renewable energy from 2007 to 2023 by testing the applicability of the energy security framework. The electricity crisis presents itself through regular electricity cuts, extreme power tariff rises and a lack of long-term sustainability due to the high reliance on coal and Eskom, the monop

Development of an Environmental Functional Gene Microarray for Soil Microbial Communities

Functional attributes of microbial communities are difficult to study, and most current techniques rely on DNA- and rRNA-based profiling of taxa and genes, including microarrays containing sequences of known microorganisms. To quantify gene expression in environmental samples in a culture-independent manner, we constructed an environmental functional gene microarray (E-FGA) consisting of 13,056 mR

A machine learning model for prediction of 30-day primary graft failure after heart transplantation

Background: Primary graft failure (PGF) remains the most common cause of short-term mortality after heart transplantation. The main objective was to develop and validate a risk model for prediction of short-term mortality due to PGF after heart transplantation using the ISHLT Heart Transplant Registry. Methods: We developed a non-linear artificial neural networks (ANN) model to evaluate the associ

TUNDRA

In this bachelors project I am exploring how Phase Change Material can be applied into an office chair to give a cooling effect and reduce the need for air conditioning. The motivation for the project was to find solutions to lower the energy consumption. The design process includes research and ideation to a developed concept with a display prototype.

Growth-collapse mechanism of PEI-CTAB films at the air-water interface

We reveal a growth-collapse mechanism for self-assembled films of polyethyleneimine (PEI) and cetyltrimethylammonium bromide (CTAB) at the air-water interface. The work involved the quantification of film thickness on the micron scale through tracking oscillations in the amplitude and phase angles using single-angle, single-wavelength ellipsometry. Our results allow us to propose the following int

Fatigue Reliability Based on Predicted Posterior Stress Ranges Determined from Strain Measurements of Wind Turbine Support Structures

In the present paper, an approach for updating the continuous stress range distribution of a welded connection of a wind turbine support structure with predicted information from strain measurements is presented. Environmental conditions, such as wind or, in offshore fields, waves and currents, in combination with rotor excitations generate cyclic stresses affecting the reliability of welded joint

The Gaia-ESO Survey : Preparing the ground for 4MOST and WEAVE galactic surveys: Chemical evolution of lithium with machine learning

Context. With its origin coming from several sources (Big Bang, stars, cosmic rays) and given its strong depletion during its stellar lifetime, the lithium element is of great interest as its chemical evolution in the Milky Way is not well understood at present. To help constrain stellar and galactic chemical evolution models, numerous and precise lithium abundances are necessary for a large range

Chrono-chemodynamical analysis of the globular cluster NGC 6355 : Looking for the fundamental bricks of the Bulge

The information on Galactic assembly time is imprinted on the chemodynamics of globular clusters. This makes them important probes that help us to understand the formation and evolution of the Milky Way. Discerning between in-situ and ex-situ origin of these objects is difficult when we study the Galactic bulge, which is the most complex and mixed component of the Milky Way. To investigate the ear

Configurations of underreported cyclist-motorised vehicle and single cyclist collisions : Analysis of a self-reported survey

Lower severity cycling collisions, and single cyclist collisions (or single bicycle crashes) are significantly underreported in police statistics, introducing biases into the types of collisions that are available for analysis. Furthermore, many lower severity collisions do not appear in other collision data sources (e.g. hospital and insurance data). This in turn affects priorities for cyclist sa

REPP - Rubber Environment Protection Profiles

The lack of circular economy is a global problem; cur- rently, we use more resources than what is sustainable for our planet. One material that is highly critical to take action towards sustaining is the raw material of natural rubber. By reusing the rubber that currently is used in ti- res for other products, we can create a stronger circular economy for the material and thus use less new res

Solutions from space? A dynamic capabilities perspective on the growing use of satellite technology for managing sustainability in multi-tier supply chains

Distant upstream tiers in supply chains are hotspots for sustainability issues that expose focal firms to growing reputational, financial, operational and legal risks – yet sustainable supply chain management (SSCM) practice and research still focus on dyadic buyer-supplier relationships due to poor upstream transparency. Recently, however, focal firms have started adopting satellite technology as
