In addition to its complex structure, the cerebral cortex has multiple functions exclusive to humans. Unfortunately, it also plays a crucial role in multiple neurodevelopmental and psychiatric disorders. Although we know very little about human-specific gene regulatory mechanisms during brain development, non-coding RNAs are evolutionarily non-conserved, evolve faster, and are highly expressed in
This thesis deals with the significance of institutional structures and their outcomes when combating corruption. It investigates Rwanda's outstanding progress in implementing anti-corruption policies and building strong institutions to fight corruption. Concepts such as the quality of government and good governance has been used to explain the country’s success within the anti-corruption fram
This thesis is devoted to the analysis of the I-V properties of axial InP pn-junction nanowires made for solar cell application. A novel method has been used to measure the I-V characteristics very accurately and reproducibly, using scanning tunneling microscopy (STM). The STM is used to first image the nanowires from top and then form a low resistive point contact between the STM tip and an indiv
Volunteers fill an important function in the social work that constantly and in various ways goes on in our society. Without the volunteers' involvement there is a risk that many more people fall between the cracks than actually do, even in the Swedish welfare state. Since volunteers are people whose resources are finite, it is important to gain insight into what motivates, encourages and even
Various Helicobacter species have been isolated from the stomach, intestinal tract and liver of a variety of mammalian and some avian species, and Helicobacter DNA has been detected in human bile and liver samples. An immunoblot assay was established to analyse serum antibody responses to non-gastric Helicobacter species in patients with autoimmune liver diseases, in comparison with healthy indivi
Vocal tract area functions estimated from 38 sets of X-rayed vowel articulations collected from the literature and from new X-ray motion films of English and Arabic speech reveal four constriction locations: along the hard palate, along the soft palate, in the upper pharynx and in the lower larynx. Each location is appropriate for a definable class of vowel qualities, confirming the quantal nature
I höst kommer rymdobservatoriet Gaia att sändas upp. Ett av dess mål är att mätapositionen av stjärnor med väldigt hög noggrannhet, denna positionsbestämning kallas astrometri. Gaias noggrannhet är såpass bra att det kommer bli möjligt att även mäta hur planeter när de färdas i sina banor runt stjärnor påverkar positionen av stjärnan. Astrometri kan inte ge en fullständig bild av hur planeten rörContext: The Gaia satellite will be provide astrometry with micro-arcsecond accuracy. This will allow for the determination of the orbital elements of exoplanets with measurable astrometric signature. Astrometry alone is not be able to disentangle an ambiguity in the orientation of planetary orbits, just as radial velocity is only able to give the mass of orbiting planets combined with multiplicat
Populärvetenskaplig sammanfattning Evolution av stabilitet i ett rovdjur-bytessystem För att göra en matematisk modell av hur rovdjur och byten växelverkar med varandra ställer man upp varsin ekvation för populationernas tillväxthastighet. Dessa beskriver hur rovdjuren och bytena beror av varandra och tiden. Eftersom rovdjuren är beroende av att äta byten för att överleva påverkar de bytespopulaAbstract This master's thesis aim to see if fluctuations in the environment can make a stable predator-prey system naturally evolve into an unstable system. In the paper “Prey adaptation as a cause of predator-prey cycles” (Evolution, 1997), Abrams and Matsuda uses numerical methods to investigate the stability properties of a predator-prey system and looks at the effect that the unstable pop
Denna uppsats syftar till att granska och diskutera kriminaliseringen av – och tillämpningen av straffrätten på – HIV-smittade personers sexuella kontakter där HIV-smitta överförs, eller riskerar att överföras, från en person till en annan. Upprätthållandet av ett straffhot avseende gärningar med grund i HIV är en kontroversiell fråga, i vart fall inom HIV/AIDS-arbetet på internationell nivå. Sver
The municipality is planning for the citizens and therefore the citizens should be one of the primary tools to use during the planning process. In this thesis were going to analyze a project, Fokus Dalby. It´s a project that helps the citizens of Dalby to take part in the planning process of their own community. The views of the citizens should be a critical factor in the planning process since th
Prehistorical musical instruments have been explored in archaeology more systematically since the 1970s when music archaeology was established as a field of study. The new awareness initially led to studies centred on retrieving musical instruments that had been missed and were now lost in archives. New discoveries, too, are very object-oriented. This master’s thesis ties together individual finds
Sammanfattning Spridningsrätten ger upphovsrättsinnehavaren en ensamrätt att tillåta eller förbjuda all slags spridning till allmänheten, genom försäljning eller på annat sätt. Rätten att kontrollera spridningen är bunden till fysiska exemplar. Konsumtion av spridningsrätten är en inskränkning av upphovsmannens spridningsrätt och benämns som konsumtionsprincipen. När ett exemplar av ett verk med Abstract The distribution gives the rights-holder an exclusive right to authorise or prohibit any form of distribution to the public by sale or otherwise. The right to control the distribution is tied to tangible objects. Exhaustion of the distribution right limits the rights-holder distribution right and is named the exhaustion principle. When a work with the consent of the right-holder is trans
In 1936, when the Provisional Agreement concerning the Status of Refugees coming from Germany was adopted, the same course was followed: the term refugee covered all persons coming from Germany. The definition of the term refugee was not established by the adoption of the 1967 Refugee Protocol, which created a more or less complete correspondence between the mandate of the UNHCR and treaty law. Fr
Dominant policy approaches have failed to generate action at anywhere near the rate, scale or depth needed to avert climate change and environmental disaster. In particular, they fail to address the need for a fundamental cultural transformation, which involves a collective shift in mindsets (values, beliefs, worldviews and associated inner human capacities). Whilst scholars and practitioners are
PurposeDrylands account for 47.2% of land area and contain 15.5% of global carbon (C). However, the variation in organic and inorganic C stocks across latitudinal gradients in arid and semiarid shrubland ecosystems remains understudied, and we lack in-depth understanding of the main drivers of C variation at this spatial scale.MethodsHere, we sampled soils from 95 sites across a latitudinal gradie
Dynamic glucose enhanced (DGE) MRI is used to study the signal intensity time course (tissue response curve) after D-glucose injection. D-glucose has potential as a biodegradable alternative or complement to gadolinium-based contrast agents, with DGE being comparable to dynamic contrast enhanced (DCE) MRI. However, the tissue uptake kinetics as well as the detection methods of DGE differ from DCE,
BACKGROUND: Accessibility to surgical services can impact earthquake preparedness and response. We aimed to estimate the population with timely access to surgical care in Guerrero, a Mexican state with high tectonic activity, and identify populations at risk in the event of an earthquake.METHODS: We conducted an ecological study using open government data. We extracted data from Guerrero municipal
A drawback when hobbing lead crowned helical gears is that the gear tooth will be manufactured with alignment errors, often denoted flank twist. Together with other source deviations, these errors must not exceed the predetermined tolerances if the gear is to be finished hobbed. A simulation model is developed where the hobbing process can be analysed without additional errors resulting from real
