Background: Endolichenic fungi (ELF), which live the inside the lichen thallus, contain many secondary metabolites that show various biological activities. Recent studies show that lichen and ELF secondary metabolites have antioxidant, antibacterial, antifungal, cytotoxic, and anticancer activities. Purpose: Here, the effects of an ELF extract and its bioactive compounds were investigated on the

Background: The risk of sustaining a graft rupture after anterior cruciate ligament reconstruction (ACLR) is high. Contributing risk factors are, however, still not clearly identified. Objective: The aim of this systematic review was to identify and quantify risk factors for graft rupture after ACLR. Methods: A systematic review with meta-analysis (PROSPERO CRD42020140129) based on PRISMA guidelin

Context. The formation of globular clusters remains an open debate. Dwarf starburst galaxies are efficient at forming young massive clusters with similar masses as globular clusters and may hold the key to understanding their formation. Aims. We study star cluster formation in a tidal debris, including the vicinity of three tidal dwarf galaxies, in a massive gas-dominated collisional ring around N

We propose a model with two Higgs doublets and several SU(2) scalar singlets with a global non-Abelian flavor symmetry Q6× Z2. This discrete group accounts for the observed pattern of fermion masses and mixing angles after spontaneous symmetry breaking. In this scenario only the third generation of fermions get their masses as in the Standard Model (SM). The masses of the remaining fermions are ge

The COVID-19 crisis is a global event that has created and amplified social inequalities, including an already existing and steadily increasing problem of employment and income insecurity and erosion of workplace rights, affecting workers globally. The aim of this exploratory study was to review employment-related determinants of health and health protection during the pandemic, or more specifical

In this thesis, a method that generates critical situations for autonomous vehicles with fewer resources was investigated. To produce these key examples, the strategy in this thesis explores optimization and reinforcement learning. These key examples are defined as Edge cases; these cases are situations on the border between safe and unsafe. To be able to search for them, in this paper, they are d

Matters of housing are an often-discussed topic within architecture these days. As a subject, it is often recurring in architectural media, such as books, debates, podcasts, videos, and others. Sweden, like large parts of the developed world, faces right now a multitude of unique issues related to housing. It has become an expensive commodity, especially for younger people. Most of the existing ho

This thesis takes a look at the origin, development and continuation of Thich Nhat Hanh’s literature (TNH). To do so, I first establish necessary Buddhist concepts and situate them in relation to Western ideas. I take special interest in the role of mindfulness and the Insight of Interbeing. I then explore the role of literature in traditional Buddhism, taking particular interest in the kōan. The

Spridning och etablering av invasiva främmande arter har en negativ inverkan på biologisk mångfald, människors hälsa och ekonomin. Jättebalsamin (Impatiens glandulifera) är en invasiv främmande växt som finns med på EU:s lista över invasiva främmande arter och ska bekämpas i Sverige. Flera studier har gjorts angående växtens egenskaper, spridning och påverkan på invaderade områden. Syftet med denThe spread of invasive alien species poses great risks for biodiversity, human health and economies. Impatiens glandulifera, an invasive alien plant which has been listed in The European list of Invasive Alien Species of Union concern, is widely spread in Sweden. Multiple studies have been made regarding the plant’s characteristics, spread and impacts on invaded areas. The purpose of this study i

Geography is the study of knowledge in a given location, and history is the study of knowledge over time. The combination of changes over time has always been challenging to visualize in maps. The main aim of this thesis was to analyze differences between various methods used to visualize spatio-temporal data with open-source web mapping technology. The methodology of this thesis has been split in

Denna uppsats kretsar kring prestigeskapande och formandet av social hierarki bland unga män inom den statliga institutionsstyrelsens (sis) omvårdnad. Metoden för detta arbete utgörs av kvalitativa intervjuer med institutionens personal såväl som litteratur baserat kring kulturellt, symboliskt och ekonomiskt kapital och dess förhållande till individ, kollektiv och sociala fält.

The purpose of this thesis work is to investigate whether a dynamic chassis can possibly enhance hygiene chairs used in hospitals and elderly care. The problem with a lot of today’s products is the difficulty of manoeuvring the hygiene chair in tight spaces, and to allow for a high enough seating position to contribute to a more ergonomic working position for caregivers during showering. Thereof i

We demonstrate self-compression of 173 fs pulses centered at 1030 nm down to 19.5 fs through electro-optic phase modulation by the phonon-polariton waves generated in a phase-matched intra-pulse difference-frequency mixing.

During the 21st century, public diplomacy and branding received a new angle and application closely related with the meaning of securitization. Even though the importance of this meaning, researchers nowadays notice a research gap considering the three above-mentioned fields. NATO, as a popular security brand, represents an under-researched sui generis organization that gets involved with securiti

A weakness in research on welfare regimes is that solidarity and deservingness has often been analysed unidimensional in relation to a capitalist class-structured society. Feminist and postcolonial scholars have argued that welfare regimes need to be situated and analysed in an intersectional setting. In this chapter, focussing on Sweden, a central contention is that in analysing welfare provision
