Popular science summary Spatial Memory Accuracy in Marsh tits (Poecile palustris) - an experimental study Food hoarding is a prevalent food protection behaviour in nature and it is performed by variety of animals including some mammals and birds. Two main food hoarding strategies have been observed among animals; larder hoarding and scatter hoarding. Larder hoarders aggregate all their food in
Microelectrodes today and nanoelectrodes tomorrow further studies in fields of science such as neurobiology and electrophysiology, and are already in use as neural prosthetics. When electronic devices are used in biomedicine, especially when needed for chronic implantation, their ongoing downscaling is largely motivated by two aspects: biocompatibility and specificity. It has been shown that downs
This thesis has investigated the formation of sectarian identities on Northern Ireland. The thesis argues that the key factor in creating and maintaining sectarian identities is cultural violence. Cultural violence creates and maintains sectarian identities by closing the historical narratives, the identities and thus putting the society in melancholia. The thesis has investigated republican and l
Detrital zircon were sampled from five rivers in Ghana and they were analysed in situ for U-Th-Pb, O and Lu-Hf isotopes. Based on the analyses, their U-Pb crystallisation ages, δ18O isotope ratio, εHf and Hf-model ages were determined. This provides information about the origin and crustal evolution of the Palaeoproterozoic bedrock in Ghana. The U-Pb crystallisation ages of the zircon mainly range
This thesis examines the possibility to combine droplet generation techniques together with acoustic particle manipulation in microfluidics to achieve focusing of particles inside micro droplets. In the thesis I introduce the reader to the general concepts of microfluidics, droplet dynamics, acoustics and microfabrication which are the basis for my experiments. The practical work focuses on the im
Populärvetenskaplig sammanfattning: Effekter av förorenat vatten på grödor Sötvatten är en allt mer begränsad råvara och snabbt växande befolkningar i länder med begränsande vattenresurser är speciella problemområden. Egypten är ett sådant land, vars enda källa till sötvatten är Nilen. Egyptens befolkning var 21 miljoner 1950 och beräknas kunna vara 129 miljoner 2050. Alla dessa människor behöveAbstract The Bahr El-Baqar drain is considered one of the most contaminated waters in Egypt, and along the drain the farmers use its water for irrigation. This study aimed to investigate effects of this irrigation water on crops, with special focus on metal contaminants, using wheat (Triticum sp) as model species. Also, protective effects (against heavy metal poisoning) of adding mycorrhiza form
Popular science summary Growth promoting effects of Trichoderma harzianum on sugar beet Imagine if a plant could be prepared to a pathogen attack before the attack occurs, or if a plant could grow stronger, without an excessive addition of inorganic chemicals. It can, it just need a little help from a fungus. The fungus that stimulates plants is called Trichoderma harzianum. It induces both p
Denna psykologexamensuppsats ingår i ett forskningsprojekt som finansieras av Forskningsrådet för hälsa, arbetsliv och välfärd (FORTE). Den aktuella studiens syfte var att undersöka sambandet mellan arbetsplatsrelaterat ociviliserat beteende och psykisk hälsa. Vidare undersöktes om det för sambandet mellan ociviliserat beteende och psykisk hälsa spelade roll om utövaren var chef eller kollega. SyfThis master thesis in psychology is part of a research project financed by the Swedish Research Council for Health, Working Life and Welfare (FORTE). The purpose of the present study was to examine the relationship between workplace incivility and mental health. It was also of importance if the instigator of incivility was a superior or a colleague and whether this affected the relationship betwee
The topic of the thesis is re-initialization of multistep methods for the solution of ordinary differential equations, in which there are frequent discontinuities in first or higher derivatives. There are self-starting algorithms to start or restart a multistep method. It is normally started by first using a one-step method and then increasing the order successively until the working order is reac
The road haulage sector experiences a considerable amount of inefficiency, characterised by sub-optimal utilisation of an individual vehicle’s cubic load fill and weight hauling capacity. This study firstly aims to understand why – despite its evident economic and environmental cost – this phenomenon has existed over the years. Next, an overview of initiatives and opportunities for improving freig
The use of area-based approaches in urban regeneration is widely accepted in the European community. As these projects are based on the context of the focal area, there is no one-size-fits-all solution on how to design and implement those. The Eco-city Augustenborg project is an environmentally-led urban regeneration project initiated in Malmö in 1998. Today, fifteen years after the project was in
The increase in population and urbanization has led to widespread concern about the resulting volume of consumption. This is especially problematic in the housing market, where home size continues to grow. In the United States the average size of a single-family home has doubled since 1950, leading to a profound environmental impact. This paper will seek to address the problem of overconsumption b
Social media has become the most popular communication channel. Large amounts of information flows are being exchanged between users. The information shared on social media is seen as more reliable than the information found on traditional media. Companies have already incorporated social media as one of their communication channels. However, the evolution of social media has occurred in such a br
Responsible investment is a movement to integrate environmental, social and governance (ESG) considerations in institutional investors’ investing activities.

Principerna om oskyldighetspresumtion och fri bevisprövning existerar med det gemensamma målet att nå så pass materiellt korrekta domar som möjligt. Dessa två rättssäkerhetsprinciper hamnar på ytan i konflikt med varandra när den tilltalade använder sig av sin rätt att tiga för att undvika att belasta sig själv; tystnaden får inte tolkas negativt för den tilltalade, men domstolen är å andra sidan The principles of presumption of innocence and free evaluation of evidence share a common raison d’être in their strife to produce as materially proper judgements as possible. However, these two principles of rule of law seemingly appear to conflict when a suspect exercises his right to remain silent in order to avoid self-incrimination; a suspect’s silence may not be interpreted negatively as evi
Ämnet för denna uppsats är näthat vilket kan innebära brott som förolämpning, förtal och ofredande. Men trots att ärekränkningslagstiftningen är vedertagen är den inte helt vattentät. Ärekränkning är ett gammalt hedersbrott som sedan lång tid tillbaka har reglerats i svensk straffrätt. I Sveriges strafflag från 1864 (SL) avsåg förtalsbestämmelsen att värna om den enskildes goda namn och medborgerlThe subject of this essay is net hate, which can implicate felonies such as insult, defamation and harassment. Even though the Swedish rules specific to defamatory acts are recognized, they are far from comprehensive. Defamation, an offence that violates someone’s honor, is an old crime in the Swedish history of law. In the Criminal Law (SL) from 1864 the rule of defamation was intended to protect
