Evolution av skadeinsekter och deras naturliga fiender Dagens jordbruk kan använda sig av biologisk kontroll som ett alternativ till kemiska bekämpningsmedel. Naturliga fiender till skadeinsekter introduceras då i jordbrukslandskapet för att begränsa skadeinsekterna. Kunskap om hur skadeinsekter anpassar sig över tid kan vara avgörande för hur effektiv biologisk kontroll är. En generell teoretiskBiological control is a form of agricultural practice, where a pest’s natural predators are introduced or favored in the agricultural landscape to increase predation on the pests. This increase in predation is beneficial for production but can also drive co-evolutionary adaptation and even diversification within the pest communities which, in turn, may lead to predator responses and diversificatio

Wood decay fungi are often classified as either brown rot or white rot, depending on their mechanism of accessing nutrients in wood. This dichotomy assumes that white rot fungi break down lignin with various enzymes, while brown rot fungi leave it mostly unmodified and instead bypass it with diffusion of small molecules to reach the desired hemicellulose and cellulose. The effect of different sour

Finns alltjämt spår av BT Kemi i åvatten och sanerare? En av Sveriges största miljöskandaler håller på att klaras upp med en slutlig sanering. I 50 år har föroreningarna legat i marken och inte brutits ned. Sedan 1970-talet har kemikalier spridit sig till naturen och påverkat ekosystem och människor. I världen är bekämpningsmedel ett stort problem ur miljö-och hälsosynpunkt och kan skada männiPesticides are considered to protect crops from damage from example weeds, insects and molds but they are a global problem from environmental and health point of view. A pesticide producing factory in Sweden, known as BT Kemi, mainly produced phenoxyacetic acids, chlorophenols and chlorocresols between 1965 and 1977. Pollutants have been spread into the environment when the factory was active. The

Although primarily targeting the respiratory system, coronavirus disease 2019 (COVID-19) also manifests with central nervous system (CNS)-related symptoms in up to 80% of the patients. Little is known not only about SARS-CoV-2 neuropathology, but also about the clinical course of pre-existing CNS autoimmune disease and concurrent SARS-CoV-2-infection. Multiple sclerosis (MS) is the most frequent

Clinical models are increasingly employed in medical science as either diagnostic or prognostic aids. Machine-learning methods are able to draw links in large data that can be used to predict patient risk and allow more informed decisions regarding treatment and medication intervention. An advanced clinical predictor, HRDetect, can determine loss of homologous recombination-based repair pathways i

The essay examines the cause and effects of political culture, a political family consisting of socioeconomic factors, that may aim to challenge the state of democracy. The aim of the study is to understand and examine the rising trend of democractic backsliding in which contributing factors from the theories of political culture may have led to today's global fall of democracy. The main mater

"You are part of something bigger... You work with life.": A study about social horticultural projects- gains, obstacles and possibilities. The public interest in gardening and horticulture is growing, in Sweden and internationally. Despite this, social horticultural projects still earned little attention in Swedish research. This paper aimed to examine social projects that use horticul

The purpose of this study was to explore the situation of disabled children and their access to education in a village in northern Bali, Indonesia. The method used was ethnographic with participant observations, and the empirical material was collected during six weeks with ten families in their homes and at the facility of an NGO. Eight volunteers at the NGO were also informants. The questions th

The identification of the characteristics of drought are of great importance in water resources planning and management. This study explored the characteristics of drought at Limpopo River Basin (LRB) from 1918 to 2018. Two time scales were used; they were the 3-month and 12-month time scales using the Standardized Precipitation Evaporation Index (SPEI), with the aim of studying the characteristic

The exponential-6 (exp-6) potential is an intermolecular pair potential that is widely used to model fluids at high densities. The path from molecular interaction to equation of state (EOS) for a gas is not straightforward however. Monte Carlo methods and molecular dynamics give accurate results but are too slow for demanding applications like detonation modelling or numerical simulations of react

Den här uppsatsen utforskar möjligheten till miljömässigt motiverad intervention (vilket i uppsatsen är definierat som ekologisk intervention), med syfte att tvinga upphörande av annan stats miljöförstöring med global påverkan, och hur en sådan lösning skulle påverka det internationella klimatet politiskt och juridiskt. Uppsatsen utgår ifrån de bakomliggande miljörättsliga och folkrättsliga princiThis thesis explores the possibility of environmentally motivated intervention (which in the essay is defined as ecological intervention), with the purpose to force another state to stop global effect pollution, and how such a solution would affect the international legal and political climate. The thesis is based on the underlying environmental law and international law principles to provide a de

This qualitative study was about examining how the activity organizers in GoFaR work to meet, motivate and support the young people to keep them in a meaningful everyday life and thus promote their health. GoFaR was a project at Socialförvaltningen in Helsingborg. GoFaR stands for jointly arranged physical activity on prescription. The method was developed based on the FAR-method (physical activit

As a result of globalization and postmodern confusion, simple place-based identities may be becoming obsolete. Malmö Finns, on the other hand, are part of a thousand-year-old tradition of migration from Finland to Sweden and a long history of in-betweenness. Inspired by phenomenological approaches to geography, this thesis explores the mental landscapes of Malmö Finns and aims to understand how th

Denna studie har syftat till att undersöka den retoriska potential som hip hoppens lyrik, rap, skulle kunna besitta i klassrumssammanhang. Undersökningen intresserar sig för dess effektivitet som minnesstrategi men också dess potential som ett media att förmedla kunskap. Genom en övergripande analys av begreppen retorik och hip hop synliggörs detta och undersöks därefter genom autoetnografisk aktiThis study has aimed to explore the rhetorical potential that hip hope poetry, rap, could possess in classroom contexts. The study is interested in its effectiveness as a memory strategy, but also its potential as a media to convey knowledge. Through an overall analysis of the concepts of rhetoric and hip hop, this is made visible and then investigated through autoenographic action research. The r

Studiens syfte är att undersöka hur svensklärare arbetar med skrivundervisning generellt och hur svensklärare arbetar specifikt för att stötta flickor med ADHD. Datainsamlingen skedde under hösten 2020 genom semistrukturerade kvalitativa intervjuer över Zoom. Antalet svarande var tre lärare från högstadieskolan och en lärare från gymnasieskolan. Svaren jämfördes och ställdes mot varandra. ResultatThe aim of the study is to investigate how teachers of Swedish work with teaching writing in general and specifically to support girls with ADHD. The data collection took place during the autumn of 2020 through semi structured qualitative interviews conducted over Zoom. Three teachers from year 7 9 in the comprehensive school and one teacher from the Upper Secondary school part took in the intervi

The purpose of our study was to examine the meaning of the word clan in the Swedish press and social debate in 2020. We have studied how the word clan was used over time and its impact in the newspapers in 2000, 2010, and 2020. We were curious about how the concept clan was presented in the Swedish press. A qualitative approach was chosen, as it offers an interpretive understanding of the word in

The European Spallation Source (ESS) is an accelerator driven research facility under construction. Once commissioned, a linear accelerator supplies protons to a target, whereupon neutrons are generated through a process called “spallation”. Neutron beam time will be available for a variety of scientific experiments. Ionising radiation and the activation of material exposed to it is a consequence

Uppsatsen behandlar frågan kring huruvida EU:s sanktionsförfarande mot personer och enheter i syfte att bekämpa terrorism är förenligt med grundläggande rättssäkerhetskrav med fokus på förutsebarhetskravet och processuella rättigheter. Internationella sanktioner är ett instrument för att skapa fred och säkerhet samt främja demokrati och mänskliga rättigheter. Användningen av sanktionsåtgärder har This thesis addresses the question of whether EU sanctions against certain persons and entities to combat terrorism are compatible with fundamental principles of legal certainty, concentrating on predictability and procedural rights. International sanctions are coercive political and legal measures imposed to ensure peace and stability and promote democracy and human rights. The use of sanctions h

The thesis explores the interaction between finance and the state, how the conditions of that interaction has changed and how that may affect the international financial system. It combines an evolutionary approach to geopolitical theorizing and complexity theory to suggest a basic model for the system-level analysis of the interaction between states in the contemporary international financial sys
