Variations in molybdenum isotopic composition, spanning the range of similar to 2.3 parts per thousand in the terms of Mo-97/Mo-95 ratio, have been measured in sediment cores from three lakes in northern Sweden and north-western Russia. These variations have been produced by both isotopically variable input of Mo into the lakes due to Mo isotopic heterogeneity of bedrock in the drainage basins and

BACKGROUND: Primary cervical screening with both human papillomavirus (HPV) DNA testing and cytological examination of cervical cells with a Pap test (cytology) has been evaluated in randomized clinical trials. Because the vast majority of women with positive cytology are also HPV DNA positive, screening strategies that use HPV DNA testing as the primary screening test may be more effective. METHO

In the central Himalayas, water dynamics are expected to change due to multiple factors like climate change, hydro power development and shifting land use practices. This thesis looks at possible changes in water dynamics in Marsyandi river basin, Nepal, as well as causes to those changes and how they are perceived locally. Grounded in critical physical geography, the study uses mixed methods an

This is a thesis project, analysing data from high-resolution imaging observations, specifically speckle imaging, as a follow up study of exoplanet host stars observed with K2, the second operational phase of the space telescope Kepler. The project was accomplished at NASA Ames research center under the guidance of Rachel A. Matson, during an internship in collaboration with the Swedish National S

Since the 1800’s the agriculture has changed and intensified significantly, going from small scale farming to large homogenous arable landscapes with fewer grazing animals, more fertilizers and pesticides. In Sweden, this pattern of intensification has been very distinct, especially in Scania, which today is dominated by plains. This has left substantial changes in the surrounding ecosystems, affe

Shale gas extraction commonly known as fracking had support from the UK government with their ‘all out for shale’ policy. Despite this industry has struggled to establish itself mainly due to strong opposition from communities concerned about environmental and health impacts. Most research into the impacts of fracking is concerned with either environmental degradation or physical health impacts wh

Three-part parenting is an approach that social services in Sweden should use in collaboration around a child placed in foster care. It describes how foster home, parents and social services share responsibilities for the welfare of the child. The purpose of this study was to illuminate the state of knowledge about the approach among social workers working with children and adolescents in Sweden.

Leaving a sustainable society for our children is considered an arbitrary goal for the environmental work that is currently taking place in Sweden. Today, 140 million tonnes of non-hazardous waste is generated in Sweden, which is unsustainable. 31% of the non-hazardous waste is traced to the construction industry, the mining industry excluded. Today, the waste is an unused resource that is purchas

Despite the extent of research on domestic violence, few studies have been conducted on the partner violence to which boys are subject to girls in Sweden. The purpose of my paper was to analyze what support-seeking violent boys choose to talk about when they talk to a support service. Furthermore to investigate how they feel and reflect on their actions and how they relate to change in their relat

Deteriorating water quality is a challenge which affects people of the entire world, with a growing population and increased industrialization worldwide. The problem is especially apparent in many developing nations where water resource management must be improved to secure a future sustainable supply. This study was undertaken as a bachelor degree within the MFS-program funded by SIDA. The study

Outdoor climate has considerable impact on the indoor climate and it is therefore important to adapt the buildings to the climate. This thesis shows how to improve indoor climate in a climate which it is hot, dry in the summer and cold in the winter. My investigative unit is a middle class house in the town Baalbek in Lebanon and the purpose of the study is to come up with proposals on possible so

Popular science Using remote sensing to assess drought in Somalia Somalia, the country in East Africa in a region referred to as Horn of Africa is in a civil war, conflict and unrest since 1991. The prolonged conflict increases the impact of droughts in the country which is already prone to drought continuously. The country is frequently exposed to drought, occurring moderately every 3-4 years a

Purpose: To investigate incidence and location of locoregional recurrence (LRR) in patients who have received postoperative locoregional radiation therapy (LRRT) for primary breast cancer. LRR-position in relation to applied radiotherapy and the primary tumor biological subtype were analyzed with the aim of evaluating current target guidelines and radiation therapy techniques in relation to tumor

Background and Purpose- Psychosocial factors can have implications for ischemic stroke risk and recovery. This study investigated the effect of genetically determined risk of depression on these outcomes using the Mendelian randomization (MR) framework. Methods- Genetic instruments for risk of depression were identified in a discovery genome-wide association study of 246 363 cases and 561 190 cont

Background: Somali women suffer from one of the highest maternal mortality rates in the world. Somalia characterises a specific low-income country situation with a mix of newly urbanized and nomadic culture combined with a frail health care infrastructure set in a post-conflict era. Very little is known about the effects that these contextual factors can have on maternal mortality. Objectives: To

Anaplastic thyroid cancer (ATC) is a rare and highly aggressive thyroid malignancy, usually resistant to conventional therapeutic strategies. The prognosis of ATC is extremely poor with a median survival rate of 6 months. Current treatment therapy includes surgical resection in combination with external radiotherapy and chemotherapy. The underlying mechanisms involved in ATC tumorigenesis is under

The sharing economy is an emerging niche for innovation capable of disrupting established socio-technical and economic regimes. Because of this potential to cause radical changes in a wide array of domains, research in multiple disciplines addressing various aspects entailing this phenomenon is proliferating. In this emerging body of literature, the understanding and framing of the sharing economy

Background: To determine characteristics that might affect survival times in Alzheimer’s disease (AD) patients treated with cholinesterase inhibitors (ChEI) in clinical practice, and create statistical models of estimated life-span after AD diagnosis. Method: The Swedish Alzheimer Treatment Study (SATS) is a prospective, observational, multicenter study to evaluate the use of long-term ChEI therap

Aims/hypothesis: Type 1 and type 2 diabetes differ with respect to pathophysiological factors such as beta cell function, insulin resistance and phenotypic appearance, but there may be overlap between the two forms of diabetes. However, there are relatively few prospective studies that have characterised the relationship between autoimmunity and incident diabetes. We investigated associations of a
