Nano-sized (10(-9)-10(-7) m) particles offer many technical and biomedical advances over the bulk material. The use of nanoparticles in cosmetics, detergents, food and other commercial products is rapidly increasing despite little knowledge of their effect on organism metabolism. We show here that commercially manufactured polystyrene nanoparticles, transported through an aquatic food chain from a
Idrottsrörelsen och dess organisation är speciell. Den åtnjuter en stark autonomi i förhållande till det allmänna och har i högre grad än andra icke-statliga system stora likheter med nationella rättssystem avseende bl.a. reglernas omfattning. Samtidigt erhåller den stora resurser från det allmänna för att kunna bedriva rörelsen. Medlemmarna i en idrottsförening binds på avtalsrättslig grund av hiThe sports movement and its system are special. The movement enjoys a strong autonomy relative to the rest of society and it is more similar to public legal systems than other non-state systems in regard to the extent of its rules. At the same time, it receives large appropriations from the public in order to be able to maintain a functioning system. The members of a sports association are legally
Alla är vi barn i början. Med stigande ålder utvecklas förmågan att skilja på vad som är rätt och fel. Unga personer har begränsade möjligheter att bedöma risker och överblicka konsekvenserna av olika beslut. Likväl kan skadeståndsskyldighet bli aktuellt redan i ett tidigt skede av livet. Det civilrättsliga regelverket har en betydligt tuffare inställning till barns ansvar än vad straffrätten har.We all start out as children. The ability to distinguish between what is right and wrong develops with increasing age. Young people have a limited capability to assess risks and foresee the consequences of their decisions. Despite this, liability for damages can become a matter at an early stage of life. The regulations of civil law have a much tougher approach to children’s responsibility than th
While many crystals, both natural and artificial, grow isotropically, there are examples of crystals growing anisotropically. The aim of this theoretical study was to confirm the growth modes displayed by three different crystals, representing 3D, 2D and 1D structures. This was done by using energetic calculations with both molecular mechanics, with ReaxFF$_{ \textrm {SiO}}$ as the force field, an

We live in a time where there is an increasing focus on the environment, in terms of classification of vehicle emission standards and environmental zones. Along with this and the fierce market competition that exists, it is odd that a greater effort has not been made in making material-transport more effective by renewing the tarmac on our road-network. The purpose of this report is to show the sa
Det tilltagande inslaget av ett cyberelement i samhället, i såväl civila som militära kontexter, har lett till en ökande förekomst av cyberoperationer, utförda av individer, grupper eller stater; antingen direkt eller indirekt. Den mellanstatliga rätten till självförsvar utgör ett undantag till stadgans våldsförbud och förutsätter, i såväl art. 51 FN-stadgan som internationell sedvanerätt, ett väpThe increasing presence of a cyber element in our society, in civilian as well as in military contexts, has led to an increased amount of cyber operations, carried out by individuals, groups or states; either directly or indirectly. The right to self-defense between states is an exception to the Charter's prohibition of violence and presupposes, in both Article 51 of the UN Charter and customa
Det här är ett masterarbete kring relationen mellan ADHD och musik, inte inom medicin. Med arbetet vill jag lyfta upp fördelar, hyperförmågor och den stora kreativa potential som ADHD ger mig som musiker. Jag fick ADHD-diagnosen först efter flera års studier på Musikhögskolan, och hade innan dess levt 30 år med bara nackdelar med ADHD. Eftersom jag var missnöjd med medicinen tänkte jag “out of theFinding my inner Nimrud - my life as an ADHD musician This is a master's thesis on the relationship between ADHD and music, not in medicine. With this work, I aim to highlight the advantages, hyper-abilities and great creative potential that ADHD give me as a musician. I got the ADHD diagnosis after 4 years of study at the Academy of Music. Before that I lived 30 years with only the disadvanta

Ett första steg i arbetet att uppskatta kolflödet mellan landbaserade ekosystem och atmosfären är att så precist som möjligt analysera kvantiteten ovanjordisk biomassa. LiDAR teknologi har i detta avseende visat sig vara ett värdefullt verktyg. Det överlöpande målet med denna studie är att utveckla en förenklad metod, baserad på fjärranalys, för att uppskatta ovanjordisk biomassa för individuella As a first step in the assessment of carbon flux between the terrestrial environment and the atmosphere it is important to accurately quantify the carbon stock of forest ecosystems. LiDAR technology, in this respect, has proved to be a valuable tool, able to provide accurate estimates of aboveground biomass (AGB). The overall goal of this study was to develop a simplified method for assessing AGB

Populärvetenskaplig sammanfattning Klimatet i region Sahel varierar på en årlig och decennielång basis. Under slutet av 1900-talet har den utsätts för en period av markant torka. Mellan 1960 och 1990 nådde nederbörden nivåer av bara 40 % av genomsnittet. På grund av detta skattas perioden en av de makantaste klimatiska fenomen i hela världen under 1900-talet. Torkan har orsakat stora konsekvenser The Sahel is a region of large interannual and interdecadal climatic variability. In the late 20th century it experienced a period of pronounced drought that lasted from the late 1960 to the early 1990s, where precipitation values reached only about 40% of the long-term mean. This is why this period counts among one of the most striking climatic phenomena worldwide in the 20th century. The consequ

The essay considers firstly the circumstances of the introduction of the prohibition to Swedish law and secondly some questions of principal importance pertaining to the prohibition. The essay then
Den svenska jämställdhetspolitiken utgår från ett övergripande mål om att kvinnor och män ska ha samma möjligheter att forma både sitt eget liv och samhället. Målet bygger på en tanke om att det existerar ett strukturellt och ojämlikt maktförhållande mellan män och kvinnor. Det övergripande jämställdhetspolitiska målet anknyter på så sätt till Yvonne Hirdmans teori om genussystemet och den underorThe gender equality policy in Sweden is based on a main objective of equal opportunities for both men and women to shape their lives as well as the society. The objective is founded on an idea that there exists an unequal relationship of power between women and men. Therefore, the objective also relates to Yvonne Hirdmans theory on the gender system and the subordination of women that follows from
The work aimed to investigate the possible correlations between observed weather data and wildland fires. Initially, a literature study was conducted to find which weather variables that affect the occurrence and size of these fires. A selection was made based on the theory, where available weather data and data from wildfire rescue operations were divided into independent and dependent variables.
The purpose of this study is to examine foster parents’ experiences of how emergency placements in foster care work and affect children.

Nightlife environments are high-risk environments for violence, hence security guards and nightclub entry hosts are necessary to guarantee guest safety. However, there is little research on their view of their own safety and vulnerability. This study examines exposure to work-related violence and feelings of (un)safety among security guards and entry hosts working in nightclubs in Malmö, Sweden. I
This thesis presents an application of machine learning techniques in a search for a high-mass resonance particle decaying into top quark pairs in high energy dijet events using the ATLAS experiment at the Large Hadron Collider. Top tagging is applied to the dijet events to select the events with top signature and suppress the background, increasing the sensitivity of the search. All the data used
