Introduction: Superfruits have been promoted as nutrient-rich food that can improve your health, however, many scientists argue that the validation of the term is based on exaggeration of the limited studies that are available. Background: The chemical composition of a food is complex and there are many substances that can affect the human body. One such group of substances are fatty acids (FAs),
Urban areas are responsible for a significant part of greenhouse gas emissions. Megacities, especially, have cumulative impacts due to different anthropogenic heat sources and urban heat island phenomena. It is therefore vital to replace fossil fuel burning heating sources with renewable sources in the current building stock. Renewable energy sources can be applied through building energy retrofit
The reason behind brain pericyte death in Alzheimer's disease Alzheimer's disease (AD) is a widespread neurodegenerative disorder with more than 46 million people living with AD worldwide. The most characteristic clinical symptoms of AD are memory loss and behavioural issues, affecting the daily life of those suffering from AD and their caregivers. Unfortunately, despite extensive researc
Mantle cell lymphoma (MCL) with Myc aberrations has previously been shown to be associated with poor survival and worse response to current treatment strategies. This study aims to investigate the association between Myc overexpression and clinical outcome and to identify drugs targeting MCL with Myc alterations. Data from the two patient cohorts BLISS and N-MCL2/3 was analyzed, and the associatio
Plantera skog i hagen eller på vetefältet? Att börja använda marken i stor skala i form av jordbruk, städer och nedhuggning av skog var en förutsättning till att den mänskliga civilisationen skulle uppstå, men det har inte kommit utan konsekvenser för planeten. Att använda marken på ett hållbart sätt är avgörande för att bemöta de stora miljöproblemen i världen som klimatförändringar och förlustenThe environmental effects, not least on biodiversity, of land use and land use change provide major challenges when sustainability goals are to be met along with demand for production and other ecosystem services. Here I systematically review literature on one major land use change, from agriculture to forest, and the implications for biodiversity. The aim is to provide information for land use de
Online dating is growing rapidly within society. In the light of the covid-19 pandemic, the popular online dating app Tinder provides a new social setting for dating and romantic relationships. There is some debate whether online dating apps liquify (devolves) love - as proposed by Zygmunt Bauman - or make dating more accessible and efficient. This thesis aims to understand and create knowledge of
Title: “With Great Freedom Comes Great Responsibility” - A Qualitative Study of Managers’ and Their Respective Employees’ Experiences of Mandatory Remote Work and Relationships in this Work Setting Authors: Anna Rebeka Dinnyes & Siri McGarvey Supervisor: Monika Müller, Lund University, Sweden Examiner: Stefan Sveningsson, Lund University, Sweden Course: BUSN49, Degree Project in Master’s P
This thesis investigates the quantization of field theories using the functional integral formalism. Gauge invariance necessitates a gauge-fixing procedure that chooses a unique field configuration from each gauge orbit. Faddeev and Popov suggested an adjustment to the action that implements gauge fixing in this framework, however it has been found that this procedure fails to uniquely fix the gau
Vi har testat en av teorierna för kvanttermodynamik med Hubbard-Holstein modellen på en dimer. Resultaten visar att effekten av fjädern är att utjämna de typiska kännetecknen i arbetet utfört av systemet. Vi har sett att systemet kan agera som ett batteri som kan laddas. Vi såg också att det var viktigt vilken ordning vi ändrade parametrarna i systemet, som vi förväntade oss av klassisk termodynamThe goal of this project is to characterize the quantum thermodynamics of a Hubbard-Holstein dimer. We explore how the standard formalism of quantum thermodynamics behaves in the context many-body physics. To this end, the simplest possible lattice model which includes electron and electron-phonon interactions is used, namely the Hubbard-Holstein dimer. The system is time evolved using exact diago

Swedish youth-centres are characterized by their vision of being a “meeting place for all”. To fulfil this vision, inclusion has become a relevant concept and tool for those working within these centres. This thesis is based on interviews with seven youth-workers and managers within youth-centres in a large Swedish municipality. The aim of the study is to investigate how youth-workers and managers
Antal fordon i trafiken börjar bli allt fler och fler. Detta leder till att vägar behöver underhållas emellanåt. För att åtgärda vägarna så krävs det vägarbetare på plats, 90% av dessa vägarbetare känner oro dagligen på sitt jobb. Anledningen till deras oro är att många trafikanter inte tar någon hänsyn till vägarbetare, de kör aggressivt, hänsynslöst och över hastighetsgränsen. Under åren 2003-20The number of vehicles in traffic is increasing. This means that roads need to be maintained regularly. To repair the roads, road workers are required on site. Ninety percent of these road workers feel anxious daily at their work. The reason for their concern is that many road users do not pay any attention to road workers, they drive aggressively, ruthlessly and over the speed limit. During the y
Over the last decades, the Swedish insurance industry has seen decreased entry barriers due to deregulation and emerging new technologies, which have the potential to disturb the stagnated and consolidated competitive landscape of the industry. Initiated by newcomers like American insurance startup Lemonade, and later Swedish Hedvig among others, there is an increased push toward digitalization, t
Type 2 Diabetes Mellitus (T2DM) have known to be one of the most common degenerative diseases which highly correlate with lifestyle, including consumption habits. It cannot be denied that the availability and accessibility to high processed food, high in carbohydrates play an important role on increasing the risk of T2DM. On the contrary, consumers’ awareness towards health and nutrition are also

Detta examensarbetet handlar om att forma en hemisfäroid från en platt honeycomb-skiva samtidigt som honeycomb-strukturen bibehålls. Honeycomb-strukturen är ett hexagonalt mönster som kan vara gjord av hexagoner, cirklar eller trianglar. Inom kartografi görs jordens sfäriska yta om till en platt representation i form av en karta. Omvandlingen är omöjlig utan förvrängning eller uppdelning i mindreThis Master thesis is about forming a hemispheroid out of a flat honeycomb while retaining the honeycomb structure through an even spread of deformation. The honeycomb structure is a hexagonal structure which can be made out of hexagons, circles or triangles. In cartography the surface of the earth, a spheroid, must be distorted or cut up in order to create a flat map. In the same way forming of
