The Viking Age saw the colonisation of most of the isles of Scotland by settlers from Norway. These newcomers brought their own customs, practices and perceptions to the Isles, maintaining close links with the Scandinavian world. However, these islands had already experienced millennia of anthropogenic change by the time of Norse settlement, and generations of previous inhabitants had populated th
Agriculture is necessary for providing nutrition to a growing global population. However, many unsustainable agricultural practices contribute to climate change, cause local pollution and disrupt natural biological and nutrient cycles. Conservation agriculture (CA) is one of the many practices that have been proposed to meet the challenge of sustainable agricultural production. CA aims to restore
I investigate to what extent spiral arms might affect axisymmetric Galactic models. As we need fully dynamical and high resolution Galactic evolutionary models to probe the structure of the dark matter halo, it is important that we use accurate mass models describing the MW structure. Before reaching to that level of effort, a great deal can be learned from fitting mass and kinematic models to dat
The interest for renewable energy within Australia is growing and the New South Wales (NSW) Government has committed to a Renewable Energy Target scheme of 20 percent renewable energy by 2020. Wind energy is a mature renewable energy resource, which has been successfully deployed for electricity generation around the world. It is further believed to be a viable option to help expand the renewable
Structural changes to agricultural landscapes due to agricultural intensification caused declines in biodiversity and abundance of animal groups providing ecosystem services and disservices to agriculture. Little is known about the relative contribution of animals to services and disservices after harvest and how these animal groups are affected by landscape configuration. Therefore, this study in
Huvudmålet med miljöbalken är att uppnå en hållbar utveckling. Detta stadgas i balkens portalparagraf och begreppet anses innehålla tre pelare som måste balanseras och tas hänsyn till: ekologisk, ekonomisk och social hållbarhet. För att uppfylla huvudmålet är det viktigt att dess underliggande delmål genomdrivs, varav straff och sanktioner är ett av dessa. Syftet med denna uppsats är att utreda huThe main objective of the Swedish Environmental Code (miljöbalken) is to achieve sustainable development. This objective is stated in the Code’s initial paragraph and the concept contains three pillars which need to be considered and balanced: ecological, economic and social sustainability. To fulfil the main objective an enforcement of its sub targets is important, criminal sanctions being one of
Om en upphandlande myndighet beslutar sig för att använda sig av egna resurser vid en anskaffning krävs ingen föregående tillämpning av upphandlingslagstiftningen. EU-domstolen har i mål C-107/98 Teckal uttalat att användande av resurser som innehas av en fristående enhet under vissa förutsättningar ska anses finnas inom den upphandlande myndighetens egna organisation. Så anses vara fallet när denIf a contracting authority decides to use its own resources upon acquisition, no prior application of procurement law is required. In Case C-107/98 Teckal, the European Court of Justice has stated that the use of resources held by an independent entity, under certain conditions should be considered within the contracting authority's own organization. Such a situation occurs when the contractin
Context. The planet-metallicity correlation for gaseous giants is widely accepted through spectroscopic studies. However, whether a similar correlation exists for terrestrial planets is a debated subject. High-precision spectroscopic abundance analysis on Sun-like stars suggested that the Sun is depleted in refractory elements with respect to its solar twins without exoplanets, likely due to the f
Context. With the goal to accurately map about a billion of the Milky Way stars, the astrometric satellite Gaia was launched in December 2013. Its high precision and sensitivity will lead to better understanding of the Galactic structure and evolution. Also, it will be possible to probe the matter distribution in the Galaxy. Aims. To study how well the Galactic matter distribution can be determin
Temperate calcareous grasslands are characterized by high levels of species richness at small spatial scales. Nevertheless, many species from a habitat-specific regional species pool may be absent from local communities and represent the dark diversity' of these sites. Here we investigate dry calcareous grasslands in northern Europe to determine what proportion of the habitat-specific species pool
Popular Abstract in Swedish Populära tidskrifter och flertalet debattörer har alltsedan 80-talet hävdat att privatisering leder automatiskt till en förbättring av företagets effektivitet. På grund av dessa diskussioner har man litat mycket på marknadskrafter, då man trott att dessa krafter kan ombilda organisationer med goda effekter. Avhandlingen är en kritik mot dessa ansatser. Författaren försöThe majority of research on privatisation has been driven by, inter alia, economics. Some economists have argued that private ownership introduces capital market pressures into inefficient state bureaucracies. Private property rights are expected to maximise the incentives for management to achieve a high level of production efficiency. The argument put forward in this research is that in so far a
Thermal manikins have been used to measure thermal properties of clothing. The use of thermal manikins has made a step forward in terms of quantifying thermal properties of clothing in a 3-D manner compared with the use of hotplates for material testing. The effects of clothing properties measured on the thermal manikins under steady state (constant manikin surface temperature and constant environ
Ghrelin is produced by A-like cells (ghrelin cells) in the mucosa of the acid-producing part of the stomach. The mobilization of ghrelin is stimulated by nutritional deficiency and suppressed by nutritional abundance. In an attempt to identify neurotransmitters and regulatory peptides that may contribute to the physiological, nutrient-related regulation of ghrelin secretion, we challenged the ghre
Aim Africa is identified by the Inter-governmental Panel on Climate Change (IPCC) as the least studied continent in terms of ecosystem dynamics and climate variability. The aim of this study was (1) to adapt the Lund-Postdam-Jena-GUESS (LPJ-GUESS) ecological modelling framework to Africa by providing new parameter values for tropical plant functional types (PFT), and (2) to assess the sensitivity
Critics suggest that Reducing Emissions from Deforestation and forest Degradation (REDD+) may not generate improvements in well-being for participating stakeholders, and may in fact undermine indigenous rights. To ensure positive social benefits from REDD+ projects, the United Nations REDD Programme has proposed core safeguards, including local stakeholder participation; free, prior, and informed
Background: Principles of brain plasticity is used in the treatment of patients with functional limitations to improve sensorimotor function. Training is included in the treatment of knee injury to improve both patient-reported function and sensorimotor function. However, impairment in sensorimotor function often persists despite training. Therefore, it was suggested that training programs need to
Background: The Ethiopian epidemic is currently on the wane. However, the situation for infected children is in some ways lagging behind due to low treatment coverage and deficient prevention of mother-to-child transmission. Too few studies have examined HIV infected children presenting to care in low-income countries in general. Considering the presence of local variations in the nature of the ep
Background: The first six weeks following a delivery is a critical period for the mother and the newborn. Despite removing out-of-pocket fees at a postnatal care access point in some parts of Uganda, few mothers utilize pre-paid services. Data from a health facility providing pre-paid postnatal care services in rural Eastern Uganda, revealed that only 17.9% of the mothers came back for postnatal c
This study assess the climate consideration in building designs and aims to explore the extent of passive house performances in warm and humid climates. Previous studies have shown significant correlation between climate conscious building designs and meaningful improvements in indoor climate. The study uses a number of indices that are used to summarize indoor climatic parameters that describes h
Studien syftar till att undersöka hur svenska kommuner kan tänkas hantera stigande havsnivåer i dess översiktliga planering. Med hjälp av geografiska informationssystems-, litteratur-, och dokumentanalyser, som tillämpades på fallexemplen Trelleborgs och Kristianstads kommun i Skåne, kunde empiri genereras samt analyseras med hjälp av en egen framtagen modell. Denna modell, eller konceptuella ramvThis thesis aims to investigate how Swedish coastal municipalities can manage rising sea levels in their master planning. By simulating sea level rise in geographic information systems (GIS), and analyzing literature along with municipal planning documents, a conceptual framework was generated. Moreover, this framework consisted of three steps: (1) Climate scenario analysis, (2) Planning strategie
