It is, with the thermal models used in today's building simulation progr¿rms,possible to calculate the major part of the heat transfer in a room with an ambientouter wall. However, there are some parameters these models calculatewith less or unknown accuracy: heat flows in poorly insulated walls or windows,heat flows in a room exposed to strong solar radiation, temperatures onthe inside of ambientAn ambient wall with a window were studied with both theoretical analyses and measurements performedunder conditions with natural climate. The method used wes to estimate the heat flow through wall and windowfrom measured temperatures and solar radiation. The longwave radiation was calculated from surface temperatures. The convective heat transfer was caculated as the difference between the heat f

AIMS: Although the epidemiological association between Type 2 diabetes and congestive heart failure (CHF) as well as cardiovascular disease (CVD) is well established, associations between diabetes-related single-nucleotide polymorphisms (SNPs), CHF, and CVD have been surprisingly inconclusive. Our aim is to examine if 43 diabetes-related SNPs were associated with prevalent diastolic dysfunction as

Realistic depictions of past land cover are needed to investigate prehistoric environmental changes, effects of anthropogenic deforestation, and long-term land cover-climate feedbacks. Observation-based reconstructions of past land cover are rare, and commonly used model-based reconstructions exhibit considerable differences. Recently, Pirzamanbein et al. (2018, 10.1016/j.spasta.2018.03.005, Spati

The aim of this thesis is to develop statistical models to reconstruct past land cover composition and human land use based on fossil pollen records over Europe for different time periods over the past 6000 years. Accurate maps of past land cover and human land use are needed when studying the interaction between climate and land surface, and the effects of human land use on past climate. Existing

Context: The global demand for food is expected to continue increasing for decades, which may drive both agricultural expansion and intensification. The associated environmental impacts are potentially considerable but will depend on how the agricultural sector develops. Currently, there are contrasting regional developments in agriculture; expansion and/or intensification in some regions and aban

The EU's Common Agricultural Policy (CAP) has had limited success in mitigating agriculture's environmental degradation. In this paper we simulate the impacts of the 2013 “greening” reform on biodiversity and ecosystem services in environmentally contrasting landscapes. We do this by integrating an agent-based model of structural change with spatial ecological production functions, and show that t

Purpose: Dronedarone may increase digoxin plasma levels through inhibition of P-glycoprotein. Using real-world data, we evaluated the risk of digitalis intoxication in concomitant users of dronedarone and digoxin compared digoxin-alone users. Methods: We used the Clinformatics DataMart, a US claims database, to identify adult patients with atrial fibrillation (AF) or atrial flutter (AFL) who conco

Amazonian ecosystems range from rainforest to open dryland vegetation, with a following decrease in biomass along the moisture gradient. Biomass can vary greatly at the ecological transition zone between grass dominated savannahs and the forest. It is not well understood if the transition zone could expand under climate change, and thereby reduce ecosystem stability and carbon storage in biomass.

Diverse and complex interactions as well as multi-actor systems characterise resource use and re- source policy. This makes system analysis a relevant tool to orient resource policy towards the long term. Analysing such complex systems requires systemic thinking, consideration of causal loops as well as time-lags and delays in system responses.In the SimRess project, system analysis encompassed pa

This thesis concerns the Articles 30, 34 and 36 of the EC-Treaty and conflicts of competence between the Community and the Member States. It deals especially with the delimitation between community concerns and national concerns in the field of non-tariff barriers to trade in community law. A new perspective concerning the application of Articles 30 and 34 of the EC-Treaty is introduced. It is arg

Procedural sedation and analgesia outside the operating theater have become standard care in managing pain and anxiety in children undergoing diagnostic and therapeutic procedures. The objectives of this study are to describe the current pediatric procedural sedation and analgesia practice patterns in European emergency departments, to perform a needs assessment-like analysis, and to identify barr

roduction of biomass for bioenergy on marginal land has been promoted to decrease the use of non-renewable energy without competing with food production. Previous estimates of marginal land and abandoned farmland in Sweden available for bioenergy production are based on general statistics and assumptions but lack in-depth analyses of potential alternative land-use values. Easily accessible public

Diverse forest landscapes contribute to reaching various forest policy goals. Understanding how the diversity of forests in a landscape is distributed among forest properties and how it is related to biogeographical and ownership factors can be helpful for effective policy implementation. We created a forest characteristics-based typology of non-industrial private forest properties aiming to captu

Ageing societies are facing major housing challenges. Understanding and addressing older adults' diverse housing needs and preferences are crucial. Having access to suitable and sustainable housing options can improve social cohesion, independence, health, and well-being. Participatory processes in housing development can enhance inclusion and democratic participation. This study uses Ramlösa Port

In post-peace agreement Colombia, everyone declared war on the forest. In the Putumayo region, these wars take their own particular forms. Scientifically, the Putumayo is described as an Andean-Amazonic rainforest. For the indigenous and local inhabitants of the Putumayo, it is the Andean-Amazonic selva. We present three wars on the forest with material and discursive specificities and critically

Multiplanetary systems spanning the radius valley are ideal testing grounds for exploring the different proposed explanations for the observed bimodality in the radius distribution of close-in exoplanets. One such system is HIP 29442 (TOI-469), an evolved K0V star hosting two super-Earths and one sub-Neptune. We observed HIP 29442 with CHEOPS for a total of 9.6 days, which we modelled jointly with

Wildfire is one of the most important disturbances affecting boreal forests. Most previous research on boreal forest fires has occurred in North American forests which have different fire regimes, tree species and are less intensively managed than their Eurasian counterparts. Recent extreme fire years have highlighted the vulnerability of the Nordic boreal forest to climatic shifts that are increa

The conference "Towards a Global Diplomatic History (c.1400-1900)" held on 30-31 May 2024 at the University of Warwick, intended to redefine the conventional Eurocentric narrative of diplomatic history. Traditionally, the history of diplomacy has been portrayed as a European-centric story, highlighting the city-states of Renaissance Italy, the Westphalian system, the rise of the modern nation-stat
