Popular science summary: How do bacteria divide? Cell division is an absolute requirement for proliferation of all bacteria and results in the bacterium being split into two by a septum. FtsZ is a protein that plays a key role in bacterial cell division. In this project, one part of the FtsZ protein was investigated with genetic methods to understand how it affects the division process. Previou
Bakgrund: Det är möjligt för företag att minska sin miljöpåverkan och reducera sina kostnader genom att ta hänsyn till returlogistik i alla delar av sin verksamhet. När det handlar om den fysiska distributionen i försörjningskedjan, så handlar returlogistik främst om att återanvända lastbärare som används för transport av gods. Dynapac Compaction Equipment AB är ett företag som använder sig av retBackground: Companies can lower their environmental impact and reduce their costs by considering reverse logistics in their operations. In the area of physical distribution, reverse logistics is concerned with the reusage of load carriers used for the transportation of goods. Dynapac Compaction Equipment AB, is a company which uses returnable load carriers (racks), for the transport of large and h
Abstract Ketoprofen, naproxen, diclofenac, and ibuprofen are four widelyused anti-inflammatory drugsthat areproduced in several kilotons each year.They end up in natural water recipients which couldvary inpH from around 6.0 to 9.0. Bearing in mind that most of thesepharmaceuticals are weak acids and therefore dissociates in different degree depending on surroundingpH and the chemical’s pKa, we ca
Abstract The barnacle, Stephanolepas muricata, a commensal epibiont of cheloniid sea turtles, occurs frequently on the sea turtles of the Golfo Dulce, Pacific Costa Rica. The aim of this study was to quantify the occurrence of S. muricata on green and hawksbill sea turtles, to describe its major attachment locations and to investigate potential routes for barnacle exposure. In-water sampling of s
Abstract: Since the ending of the Vietnam War, the Hmong in Laos have been hiding in the northern mountainous areas, fearing retribution from the People’s Revolutionary Party, whom they opposed. These areas are still currently restricted from outside contact. In 2009, Hmong refugees were repatriated from Thailand despite their unwillingness to return to Laos, fearing safety issues with the Lao Gov
Gentrification is a process of neighborhood change where the low-income group is displaced to leave the space for middle or high income residents or investors, whereas domicide is the killing of homes. The political economy and its basis operate where there is private ownership of major production on land and rent-seeking behavior of the capital and social. This is a very powerful primary influenc
Introduction: There are major limitations in the current methods for screening and diagnosis of prostate cancer. In this project, the implementation of new tests has been researched. The assessed tests in the screening phase are the 4Kscore, Prostate Health Index (PHI), Magnetic Resonance Imaging (MRI) and Prostarix. The assessed tests for use after a negative biopsy are Prostate Cancer gen 3 (PCA
The European Union released an Artificial Intelligence (AI) regulation proposal in April 2021 aimed at laying down harmonised rules for AI circulating the Union market. The purpose of this study is to critically examine how accountability and individual, collective, and social harm was approached and framed by the proposal. Previous research has shown that AI and algorithmic bias and discriminatio
Det direkta och omedelbara koppling testet, även det indirekta koppling testet i moms av EU ingår inte i momsdirektivet. Medlemsstaterna använder sig av avdragsrätten på olika sätt, vilket förvärrar problemet. Av denna anledning görs i denna avhandling sex punkter för att identifiera det direkta testets skyldigheter. Dessutom smälter de tre principerna om rättssäkerhet, ekonomisk verklighet och skThe direct and immediate link test, which is a fundamental requirement for the right of deduction to exist, is not mentioned at all in the EU VAT Directive. Additionally, Member State transposition is not a harmonised process. This leads to divergences in how different EU Member States grant the right of deduction. As a solution to this, the Court of Justice of the European Union allows Member Sta
This thesis examines the impact of secular stagnation and increasing debt levels on real long-term interest rates by estimating a SVAR model for the US, UK, and Sweden between 1902 and 2020. The results of this thesis emphasize the impact of slow productivity growth in the decline of real long-term rates since the mid-1980s, with the evidence being quite strong for the US and UK, and somewhat weak
Listeria monocytogenes is a Gram-positive facultative intracellular bacterium that causes life-threatening diseases in humans. It grows and survives in environments of low oxygen tension and under conditions of strict anaerobiosis. Oxygen-limiting conditions may be an important factor in determining its pathogenicity. L. monocytogenes serovar 1/2a strain EGD-e has been employed intensively to eluc
We aimed at assessing changes in AV nodal properties during administration of the beta blockers metoprolol and carvedilol, and the calcium channel blockers diltiazem and verapamil from electrocardiographic data.
The Åland Islands were recently ranked as Finland's healthiest region with lower prevalence of several non-communicable diseases compared with the national mean. We have compared birth characteristics of 1697 individuals born on the Åland Islands between 1937 and 1944 with contemporaneous data from the Helsinki Birth Cohort Study (HBCS; n=11,808). This is a first step towards a potential future an
Studies on the associations between cognitive abilities and life satisfaction (LS) in the oldest-old are few. The aim of this study was to explore whether abilities in six different cognitive domains could predict LS in the oldest-old 3 years later.
