In this exploratory study, the communicative role of political memes and their influence on group dynamics are examined through an abductive research approach. The method involves semi-structured interviews with politically active individuals spanning the political spectrum. This study reveals complex tribal and inter-group relationships by classifying political memes into attacking, idolising, in

Parkinson’s disease (PD) is the second most common neurodegenerative disease, and it is known for the recognisable motor symptoms. The cause of the disease is the loss of a specific cell type in the brain, called dopaminergic (DA) neurons. Significant steps towards stem cell replacement therapy of DA neurons have been made in the last few decades. Despite that, one aspect has been quite overlooked

Flavin-dependent halogenases selectively introduce halogen substituents into (hetero-)aromatic substrates and require only molecular oxygen and halide salts for this regioselective oxidative CH-functionalization. Genomic analysis of Xanthomonas campestris pv. campestris B100 identified three novel putative members of this enzyme class. They were shown to introduce halogen substituents into, e. g.,

A re-cultivation of the thermophilic fungus Aspergillus terreus TM8, and working up of its extract afforded the dichloro-benzophenone derivative, dihydrogeodin (1) in addition to the butyrolactones I (2), V (3) and VI (4). A literature surveying revealed one recent structural assignment trial for dihydrogeodin (1), however, with some inaccuracies. We report herein a full assignment of dihydrogeodi

As a continuation of our earlier research concerning the investigation of microbial bioactive secondary metabolites from the terrestrial Penicillium sp.KH Link 1809 isolate KHMM, the fungus was re-cultivated on a large scale to explore its bioactive compounds intensively. Fifteen compounds, including seven alkaloids (1-7), one sesquiterpene (8), an acetylenic system (9), two sterols, and sphengoli

För att bekämpa klimatförändringarna krävs att fossila bränslen fasas ut snarast. Många av de sektorer som idag drivs fossilt har goda möjligheter att drivas av el från förnybara källor som sol och vind i framtiden. För det krävs dock en ökad elproduktion från dessa källor, och att vi har ett elnät som kan ta emot och fördela den kraft som produceras. Idag installeras mer och mer solceller på hustIncreasing the amount of renewable generation in distribution networks is a fundamental part of the energy transition. Multiple methods exist to increase the hosting capacity in a grid, to allow larger injections of generation and more efficiently utilize existing infrastructure before operational limits are breached. In this thesis, the method studied for this is network reconfiguration. Many dis

Hybrid solutions that combine multiple renewable energy sources, such as solar power and hydro power, are gaining popularity as a means of meeting the growing energy demands while minimising environmental impacts, but also as an opportunity of connecting solar power plants to the grid in areas where this might not be possible unless large investments are made. This master thesis aims to evaluate t

In this work, different solutions for human presence detection in a door intercom device are examined. The study was conducted at a company in Lund, Sweden. The aspiration was to have a reliable presence detection to be able to put the device in sleep mode when not used, and the current solution is not optimal because of limiting design requirements and false triggers. In the project, several diff

Ökande andel småskalig solproduktion introduceras i elnäten, detta medför möjligheter och utmaningar för nätägare. I detta arbete har möjligheten undersökts om småskalig solproduktion kan bidra till att upprätthålla spänningen i nätet vid trefasiga kortslutningar. I dagsläget är det många privatägare som installerar solceller. Denna utveckling har pågått länge, men de senaste åren har intresset sThe focus in this thesis has been active power from small scale solar production and what possible impacts an increased proportion of small scale production can have, in a larger context, during short circuit (SC) faults in the grid. The main research question prompting this work was whether active power from small scale solar pro- duction can help support voltages during SC faults, and meet LVRT-

This paper investigates the significance of care between generations in Sweden. This is done towards the background of a strong narrative in both popular and sociological discourses depicting the Nordic countries in general, and Sweden in particular, as the ‘most individualized’ society in the world, where the expansive welfare state is seen as having taken over care responsibilities, leading to w

A new series of 4-arylamino-3-nitrocoumarin analogues (4–18) have been synthesized and characterized by sophisticated spectroscopic techniques (1H NMR, 13C NMR) and mass spectrometry. All the new synthesized compounds were evaluated for their in vitro cytotoxic activity against the human cervix carcinoma cell line (KB-3-1) using resazurin assay with (+)-griseofulvin as the positive control (IC50 =

Recognizing that information has long been an important asset for any organization, I explore in depth the management and use of information in contemporary information-intensive organizations such as academic libraries. Information processes, when integrated in the academic library’s daily working life can lead to workplace learning, with long term benefits. However, the literature demonstrates t

Background: Associations of body shape with breast cancer risk, independent of body size, are unclear because waist and hip circumferences are correlated strongly positively with body mass index (BMI). Methods: We evaluated body shape with the allometric “a body shape index” (ABSI) and hip index (HI), which compare waist and hip circumferences, correspondingly, among individuals with the same weig

Radiocarbon dating provides a key chronological framework for studying past environmental changes. Raw radiocarbon ages measured in samples must be converted to calendar ages using an appropriate calibration curve. Tree-ring datasets provide the gold-standard for developing a precise curve of atmospheric radiocarbon levels over long-time scales. Here, we reconstruct atmospheric radiocarbon levels

Background: There is insufficient knowledge about the systemic health effects of exposure to fine (PM2.5) and ultrafine particles emitted from typical indoor sources, including cooking and candlelight burning. We examined whether short-term exposure to emissions from cooking and burning candles cause inflammatory changes in young individuals with mild asthma. Thirty-six non-smoking asthmatics part

In this literature review, the author examines the scholarly literature of Information Management (IM) and related fields in the recognition that information has long been an important asset for any organization. However, nowadays the work environment in organizations is more complicated due to the information overload that employees experience on a daily basis. The information deluge requires emp

Therefore, the study will examine marketing communication from 2018 and 2022 to get pre- and post-pandemic persp

On 20 March 2012, the Polish Council of Ministers adopted Poland’s first Multiannual Development Cooperation Programme. Its title ‘Solidarity, Democracy, Development’ reflects the ongoing debates which surround Polish aid, and the problem with finding an agreement in defining how the Polish Official Development Assistance (ODA) should look. As I will describe in this chapter, since the process of
