The effect of shallow water table fluctuations on the evaporation and CO2 fluxes in a peatland is investigated. The fluxes of evaporation and net ecosystem exchange of carbon were measured from mid-spring to the end of summer in 2005 and 2006 and simulated independently with process models. The observed and modelled data were then compared along a gradient of water levels. Any variation along the
Denna uppsats har till syfte att undersöka huruvida det, med hjälp av teknisk analys, föreligger större möjlighet att skapa lönsamma handelsstrategier för index än för enskilda aktier. Vi kommer även att belysa hur god avkastning sådana strategier kan generera i förhållande till en jämförelsestrategi där man köper och håller tillgången under hela perioden. Handelsstrategier baserade på dubbla löpa
District heating networks are an integral part of the energy system in many countries. In future smart energy systems, they are expected to enhance energy flexibility and support the integration of renewable and waste energy sources. An important aspect of these networks is the control of flow rates, which dictates the heat delivered to consumers. This paper concerns the properties of flow rates i
Regime change is considered essential for sustainability transitions. An important source of regime change is pressure from alternative innovations developed in niches and the actors involved. Governments often play an important role in such niche-regime interactions and affect whether, and how, this results in regime change. However, an overview of the various roles governments can play with resp
Combinatorial optimization is a powerful way to solve complex problems, like planning, scheduling, or hardware verification, by expressing the problem in a mathematical form using discrete variables that can be solved by general solvers. Due to major advances in algorithms for solving combinatorial optimization problems, these solvers can tackle real-world challenges efficiently. However, as solve
This study explores how listeners use verb constructions to describe everyday sounds. It considers (i) how the verb constructions provide Gestalt to events in the form of activities, processes and states, and (ii) how the constructions correspond to different aspects of a soundscape (sound sources, acoustic properties, and listener reactions). We found that verb constructions primarily describe so
This study investigates the practical integration of Building Information Modelling (BIM) and Building Energy Modelling (BEM) for energy-efficient building design. This research explores the challenges and opportunities of openBIM-to-BEM workflows by drawing on a literature review and a real-world case study in Östergötland County, typical of the Million Programme, a large public housing initiativ
Background: The continuous global rise of end-stage kidney disease creates a growing demand of economically beneficial home-based kidney replacement therapies such as peritoneal dialysis (PD). However, undesirable absorption and exposure of peritoneal tissues to glucose remain major limitations of PD. Methods: We compared a reference (standard) automated PD regimen 6 × 2 L 1.36% glucose (76 mmol/L
Sexual dimorphism is a ubiquitous source of within-species variation, yet the community-level consequences of sex differences remain poorly understood. Here, we analyse a bitrophic model of two competing resource species and a sexually reproducing consumer species. We show that consumer sex differences in resource acquisition can have striking consequences for consumer-resource coexistence, abunda
Objective Visual expertise relies on perceptive as well as cognitive processes. At present, knowledge of these processes when diagnosing clinical cases mainly stems from studies with still pictures. Patient video cases constitute a dynamic and authentic, diagnostic challenge that may simulate seeing and diagnosing a patient in person. This study investigates visual attention and the concomitant co
Palaeomagnetic analysis of the Lakhna Dykes (Bastar Craton, India) yields a palaeopole at 36.6 degrees N, 132.8 degrees E, dp=12.4 degrees, dm=15.9 degrees, and the U-Pb zircon age obtained from one of the rhyolitic dykes is 1466.4 +/- 2.6 Ma (MSWD = 0.21, concordia age based on two analyses with identical Pb/U ages), similar to previously published U-Pb ages. Major and trace element analyses of t
With current interest from the heavy-duty industry in high-octane renewable fuels like methanol, the currently used compression ignition engines will have to be adapted to dual-fuel (DF) type combustion systems or replaced by spark-ignition (SI) engines. Since both DF and SI engines are characterized by a premixed air–fuel mixture, there is a risk that part of the unburned mixture auto-ignites bef
Industrial symbiosis, a concept derived from industrial ecology, emphasizes the collaborative and synergic production among industries. The particular focus is on cyclical flows of resources (material, energy, water, and/or by-products), in order to minimize impacts on the environment. In this way, an industry could reuse the discarded resources of another industry as an input to production. Essen
Field bio-remediation techniques (FBRT) can be a low cost method to avoid the removal of top layers of soil which are rich in organic matter and bio diversity. The use of native microorganisms in FBRT is preferable because non-indigenous species can transfer their genetic material to the environment with negative impacts on the local ecological equilibrium. Petroleum Produced Water (PPW) is an imp
Introduction: The experiences of living with Parkinson's disease (PD) from the perspective of newly diagnosed persons with PD (PwPD) have not been previously described. Aim: This study aimed to gain a better understanding of the impact of living with the early stages of PD. Methods: A qualitative interview study was conducted among nine persons, seven men and two women, from southern Sweden. Parti
INTRODUCTION: With the implementation of early reperfusion therapy, the number of complications in patients with acute coronary syndrome (ACS) has diminished significantly. However, ACS patients are still routinely admitted to units with high-level monitoring such as the coronary or intensive care unit (CCU/ICU). The cost of these admissions is high and there is often a shortage of beds. The aim o
Tilt table testing (TTT) has been used for decades to study short-term blood pressure (BP) and heart rate regulation during orthostatic challenges. TTT provokes vasovagal reflex in many syncope patients as a background of widespread use. Despite the availability of evidence-based practice syncope guidelines, proper application and interpretation of TTT in the day-to-day care of syncope patients re
