Soil greenhouse gas emissions under different land-use types in savanna ecosystems of Kenya

Field measurement data on greenhouse gas (GHG) emissions are still scarce for many land-use types in Africa, causing a high level of uncertainty in GHG budgets. To address this gap, we present in situ measurements of carbon dioxide (CO2 ), nitrous oxide (N2 O), and methane (CH4) emissions from the lowlands of southern Kenya. We conducted eight chamber measurement campaigns on gas exchange from fou

Epigenetic Mapping in Type 2 Diabetes. Glucose-triggered histone modifications in various tissues

Epigenetic modifications triggered by high glucose may predispose to diabetes risk by regulating gene expression activity. A growing body of evidence suggests that histone modification which is an essential component of epigenetic mechanism may play an important role in the development of type 2 diabetes (T2D) and its complications. In this thesis, the overarching aim is to map histone modificatio

Extracellular matrix in atherosclerotic plaques: its role in plaque stability

Atherosclerosis is a systemic disease affecting the large arteries caused by the accumulation of lipids in the vessel wall. Cardiovascular disease due to atherosclerosis is today the most common cause of death globally through its end consequences: myocardial infarctions and stroke. The extracellular matrix (ECM) is a network of structural fibrous proteins, proteoglycans and glycoproteins. ECM pro

Community and food web assembly on virgin habitat islands - The nunatak saga

Popular Abstract in Icelandic Landnám á jökulskerjum Plöntur hafa lengi verið taldar nauðsynlegar til að dýr geti numið land en þessi sýn er að breytast því rannsóknir hafa sýnt að smádýr nema oft land á undan plöntum. Landnám bæði plantna og dýra getur hafist um leið og nýtt land myndast en til að landnám takist þurfa nokkrir þættir að fara saman. Þau verða að komast á staðinn og þegar þangað erThe classical view of primary community assembly is that colonisation by plants is essential before invertebrates can establish. It has been recognised, however, that invertebrates can establish before plants, and that they may be important in the first steps of community assembly. Plant succession is well studied but assembly of invertebrates and how their dispersal abilities affect the community

Frame dynamics and stakeholders in risk governance

The EU governance of food safety and GM food and feed has gone through significant changes since the BSE crisis and food scares during the 1990s. This work focuses on one particular new feature; the role of stakeholders representing the food chain: biotech associations, farmer organizations, food and feed processors, consumer organizations and environmental NGOs. These stakeholders are not merely

Small-scale climate variability and its ecosystem impacts in the sub-Arctic

Abstract in Undetermined To improve our knowledge of climate change and its impacts on ecosystem services, and to inform local people and governments that need assistance with the development of mitigation and adaptation strategies, climate impacts need to be understood urgently at the smaller scale. On one hand, the microclimate/topoclimate is known to be strongly decoupled from the general macro

Functional and Nutritional Assessments in Geriatric Rehabilitation. A Feasibility Study

The aim was to evaluate the effectiveness and feasibility of functional and nutritional assessments in geriatric rehabilitation in Copenhagen, Denmark, and in addition to study clinically identifiable risk factors for undernutrition, association between nutritional and ADL status, feasibility and effectiveness of nutritional intervention conducted by the nursing staff, and the nursing staffs attit

Phenotypic plasticity and local adaptation in tadpoles

Amphibian larvae are plastic in many traits. Can plasticity buffer population divergence, so that local adaptation is more common in non-plastic traits? I argue that this may be the case for adaptive plastic responses. Tadpoles of Rana arvalis are shown to alter their tail depth plastically as a response to predation risk; this is a truly adaptive response. Tail depths in the field (population and

Mobile Performances : A Philosophical Account of Linguistic Undecidability as Possibility and Problem in the Theology of Religion

How to judge religions other than one's own when the means are lacking due to linguistic mobility? In the present thesis this question is mainly analysed in a Christian setting through a reading of the theologians Paul Knitter and Harold Netland. It is, however, claimed that the same question could be asked in other religious settings, also with regard to one's own tradition, and could be treated

How to think about a place not yet : Studies of affordance and site-based methods for the exploration of design professionals' expectations in urban development processes

ABSTRACTAs a part of a democratic demand for transparency in urban development processes it is important that design professionals hold the ability to scrutinise their own work process, and at certain stages let go of predefined ideas of future realities. This work revolves around how design professionals perceive options for design in such situations. A basic assumption in this work is that a des

Changes in prevalence of obesity and high waist circumference over four years across European regions : the European male ageing study (EMAS)

Diversity in lifestyles and socioeconomic status among European populations, and recent socio-political and economic changes in transitional countries, may affect changes in adiposity. We aimed to determine whether change in the prevalence of obesity varies between the socio-politically transitional North-East European (Łódź, Poland; Szeged, Hungary; Tartu, Estonia), and the non-transitional Medit

Identification of new disease mechanisms and treatments for type 2 diabetes based on genetic variants and gene expression networks

Improved understanding of the disease mechanisms underlying type 2 diabetes (T2D) is needed, and so are new treatments.A new T2D risk variant was recently identified in ADRA2A, which encodes the α2A-adrenergic receptor. The risk allele leads to receptor overexpression in β-cells that causes increased adrenergic signaling and impaired insulin secretion. We showed that the α2A-adrenergic receptor an

Prediction of disease progression in early rheumatoid arthritis. A study of some imaging and laboratory variables.

Objective: To investigate the role of magnetic resonance imaging (MRI), assessment of bone mineral density (BMD) and antibodies to citrullinated proteins (anti-CCP) in predicting radiologic outcome in patients with early rheumatoid arthritis (RA). Patients: All patients were included in the BARFOT programme (baseline). The patients had rheumatoid arthritis of recent onset with mean disease duratio

Web design for cognitive accessibility

Information and communication are increasingly being conveyed over the Internet. The forms of service and commerce that we are familiar with today will most likely be reduced in scale in the future to be replaced by new electronic solutions. For this reason, it is important that new technology be designed so that as many people as possible can utilize it. Accessibility to a range of services and i

Chronic pain and quality of life among older people.

The overall aim was to investigate chronic pain, quality of life and factors associated with pain as well as with quality of life among older people, aged 75 years and above. Further, the aim was to investigate the use of methods for pain management and their effects for those with pain and in need of help for daily living. Data were collected from a larger population study and in the first study

P-T evolotion and High-temperature deformation of Precambrian eclogite, Sveconorwegian orogen

Bergskedjor är uppbyggda av olika slags berggrund som skjutits samman i de zoner på Jorden där tektoniska plattor möts (konvergerar). Sådana processer sker i dag exempelvis i Himalaya, Alperna eller Anderna, men det finns också gamla, nu inaktiva, bergskedjor som de Skandinaviska Kaledoniderna (ca 400 miljoner år gammal) eller den Svekonorvegiska bergskedjan (ca 1000 miljoner år gammal, i sydvästr
