Jorderosion är en global utmaning som påverkar miljontals hektar mark och leder till betydande förluster i jordbruksproduktivitet och ökad sedimentering i vattendrag och sjöar. Faktorer såsom intensivt jordbruk, avskogning och förändringar i markanvändning bidrar avsevärt till detta problem. I och med klimatförändringarnas intåg med ökade extrema väderförhållanden förväntas jorderosionen att öka jSoil erosion is a significant challenge in Rwanda, particularly within the Nyagako sub-catchment, where this study focuses on a delimited area. This research investigates the sources and contributing factors of soil erosion using GIS analysis, turbidity measurements, and sediment fingerprinting with a deconvoluted MixSIAR (D-MixSIAR) model in R. The objectives were to identify erosion-prone areas,

α-Galactosidases from Aspergillus nidulans (AglC) and Penicillium subrubescens (PsGal36-2527) are exo-acting enzymes that can be found in the Glycoside Hydrolase (GH) 36 phylogenetic cluster with eukaryotic α-galactosidases. In utilizing enzymes for industrial applications, finding enzymes with a broad range of substrate specificities and high catalytic efficiencies is quite challenging. It has be

Given preschools’ important role in shaping children’s learning and development surprisingly little is known about why some Swedish preschools are much more successful in offering high-quality early education than others. Earlier research has shown that socioeconomic gaps in educational achievements can largely be explained by knowledge gaps established during the preschool years. There may be soc

Introduction: The current Tetra Brik Aseptic packaging contains a polyethylene-aluminium layer that is difficult to recycle. Alternative materials have been explored to eliminate this aluminium layer, resulting in reduced carbon emissions but a 30% shorter shelf life. This trade-off raises concerns about potential increases in food waste due to reduced shelf life. Therefore, this study aims to exp

Frågeställningar:(1)Hur upplever chefer att deras ansvar för skapandet av en god psykosocial arbetsmiljö har förändrats i samband med det ökade distans- och hybr

Solcellsparker blir både allt vanligare och allt större. I denna studie undersöks hur storleken och antalet transformatorer i en solcellspark påverkar dennas förmåga att leverera el. De rådande klimatförändringarna är en av de största utmaningar mänskligheten ställts inför. Fossil elproduktion är en stor bidragande faktor till utsläpp av växthusgaser globalt. Solceller ser ut att spela en avgöranThe main focus of this thesis has been to examine and compare how the size and number of internal power transformers affects the technical performance (robustness, power quality and efficiency) of a utility-scale PV plant. The technical performance was examined in a simulation environment (MATLAB Simulink), where a PV plant with a fixed number of PV arrays and converters, corresponding to a rated

Denna uppsats handlar i huvudsak om fenomenet celldisruption, att genomföra detta på industriell skala och analysera resultaten. Celldisruption är en process som används mycket brett inom bioteknik då själva processen går ut på att utvinna de intressanta ämnen som producerats i en cell. Idag produceras en stor mängd läkemedel cellulärt men även inom bland annat produktion av tvättmedel, ost och fäThis thesis explored the efficacy of high pressure homogenization for disrupting gram-positive bacteria of the species Lactiplantibacillus plantarum. The focus was on the impacts of homogenization pressure and the number of passes through the homogenizer as well as developing a simple method for measuring cell disruption. Turbidity measurements in combination with microscopy and laser diffraction

This master thesis presents a suggested Renovation Passport for two typical 1960s single-family houses. Following the recently approved Energy Performance of Buildings Directive (EU 2024/1275A), all member states are to implement voluntary Renovation Passports by 2026, which will aid in reaching the 2050 goal of a decarbonized building stock. The aim of Renovation Passports is to provide long-ter

Northern Ireland’s relatively recent history as a state has been marked by decades of ethnonational conflict, euphemised as “The Troubles.” While the signing of the Good Friday Agreement marked the beginning of a period of relative peace and stability, the United Kingdom’s decision to leave the European Union has raised concerns that this peace will be threatened. Academic analysis of society and

Building Information Modeling (BIM) är ett arbetssätt och samlat begrepp som ger möjlighet att visualisera önskad design i verklig storlek och dimensioner (ur olika vinklar och vyer). BIM är en smart teknik och en ny designprocess där all information och konstruktion specifikationer skapas i en digital fil. Så BIM är inte enbart en mjukvara, utan en enorm teknik. För att implementera denna teknik Building Information Modeling (BIM) is a way of working and collective concept that provides the opportunity to visualize the desired design in real size and dimensions (from different angles and views). BIM is a smart technology and a new design process where all information and construction specifications are created in a digital file. So BIM is not just a software, but a huge technology. To imp

Following the flooding event in Ringsjön within the Rönne å river basin in January 2024, this catchment area was utilized for a flood risk assessment. The study focused on the precipitation event during August 2023, known as Storm Hans. The flood risk assessment for the Rönne å catchment area was conducted using multi-criteria analysis (MCA) and geographical information systems (GIS). Seven factor

Aktivt kol har identifierats som en av de mer effektiva metoderna när det kommer till att avlägsna organiska mikroföroreningar (OMF) från avloppsvatten. Aktivt kol är ett poröst material med stor ytarea som kan adsorbera andra ämnen. Det är inget som existerar naturligt utan behöver framställas. Framställningen kan ske från i princip vilket material som helst som har en hög kolhalt. En stor del avActivated carbon has been identified as one of the more effective methods of removing organic micropollutants (OMP) from wastewater. Activated carbon is a porous material with a large surface area that allows adsorption of other substances. The material does not exist naturally and therefore has to be produced. The production can be done from any carbon-rich material and today the precursor is mai

Nymölla är en liten kustnära tätort belägen i nordöstra Skåne. Kusten utanför Nymölla, en del av västra Hanöbukten, är uppsatsens geografiska fokusområde. Under 1960- och 1970-talen anlades både massa- och pappersindustri i Nymölla, två betydelsefulla industrier för Sverige, både gällande export och ekonomi. Ett exempel av Sveriges femtiotal massa- och pappersbruk är Nymölla Bruk, en produktionsan

This thesis investigates the practical and conceptual interplay between authoritarian and green ecological governance within China’s Ecological Civilization system, post- 2013. Through a qualitative analysis of official policy documents and semi-structured interviews, the study explores how China navigates the spectrum between the ‘Green State’ and ‘Authoritarian Environmentalism’. Findings sugges

Despite a persistent reliance on conventional grey infrastructure solutions, there is increasing recognition of the vital role of nature-inclusive urban planning in managing climate risks such as floods and heatwaves while simultaneously promoting biodiversity, human health, and well-being. This multifunctionality underscores nature's intrinsic importance, reframing it as a fundamental necessi

Prominent female figures engaging in the societal debate, such as journalists and activists, tend to be targeted for online hate speech and threats disproportionally. At the same time, people in Sweden depend on an online presence to function as individuals. Feminist security studies have yet to incorporate the gendered online dimensions of hate speech and threats. This paper examines how the femi

The existence of a baryon number violating process is one of Shakarov's conditions to explain the observed baryon asymmetry in the universe. The Standard Model is nearly symmetric with respect to the baryon number, and hence we are motivated to look for physics beyond the Standard Model. In this thesis, we consider an effective field theory operator that couples the neutron to a proposed dark

This thesis critically assesses the integration of social sciences and interdisciplinarity within the international science-policy interfaces Intergovernmental Panel on Climate Change (IPCC) and Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES). I depart from a theoretical framework using the concepts of academic disciplines, interdisciplinary work and scient

Konceptet om Human Rights Cities (MR-städer) är ett relativt nytt tillägg i ramverket om mänskliga rättigheter och fokuserar på de lokala myndigheternas integrering av mänskliga rättigheter i sin oentliga förvaltning och verksamhetsstyrning. Studien avser därmed att undersöka hur ett globalt koncept tillämpas på lokal nivå i Lund, samt vilka nyckelfaktorer som är centrala i Lunds rättighetsbaserad

This paper investigates the relationship between measures of policy uncertainty, investor attention, and Bitcoin markets at a national level. To date, there are limited studies on the region-specific impact of policy uncertainty and investor attention on Bitcoin, despite evidence showing significant heterogeneities in the use, purpose, and acceptance of Bitcoin across different countries. These he
