Sammanfattning Efterfrågan på jordbruksmark har under senare år ökat dramatiskt. De huvudsakliga bakomliggande drivkrafterna till denna är jordens växande befolkning, produktivitetsminskning av tidigare fertil jordbruksmark, ökad efterfrågan på biobränsleproduktion samt de stigande matpriserna. Dessa faktorer har resulterat i att ett stort antal nationer och företag investerar i jordbruksmark utanDemand for agricultural land has increased dramatically in recent years. The drivers behind this increase are the world’s growing population, the decrease in productivity in former fertile agricultural land, the increased demand for bioenergy production and the rising food prices. These factors have led to an increasing amount of companies and nations that have made investments in agricultural lan

Aims. We aim to study the variability properties of bright hard X-ray selected active galactic nuclei (AGN) in the redshift range between 0.3 and 1.6 detected in the Chandra Deep Field South (XMM-CDFS) by a long (∼3 Ms) XMM observation. Methods. Taking advantage of the good count statistics in the XMM CDFS, we search for flux and spectral variability using the hardness ratio (HR) techniques. We al

Objective: To present the baseline data of the international TuberOus SClerosis registry to increase disease Awareness (TOSCA) with emphasis on the characteristics of epilepsies associated with tuberous sclerosis complex (TSC).Methods: Retrospective and prospective patients' data on all aspects of TSC were collected from multiple countries worldwide. Epilepsy variables included seizure type, age a

BACKGROUND: Tuberculosis (TB) is the leading cause of death for individuals infected with Human immunodeficiency virus (HIV). Conversely, HIV is the most important risk factor in the progression of TB from the latent to the active status. In order to manage this double epidemic situation, an integrated approach that includes HIV management in TB patients was proposed by the World Health Organizati

Background: Cyanobacterial blooms are of increasing concern for drinking water supply. In Sweden, a survey among drinking water producers showed that the sense of urgency was little. At 60% of the Swedish drinking water treatment plants, operators lacked monitoring strategies. To get a picture of the size of the problem the presence of cyanobacterial risk in 108 Swedish lakes was evaluated from 23

Discontinuous Galerkin (DG) methods offer a great potential for simulations of turbulent and wall bounded flows with complex geometries since these high-order schemes offer a great potential in handling eddies. Recently, space-time DG methods have become more popular. These discretizations result in implicit schemes of high order in both spatial and temporal directions. In particular, we consider

Background and Aims: The transition from outcrossing to selfing is a frequent evolutionary shift in flowering plants and is predicted to result in reduced allocation to pollinator attraction if plants can self-pollinate autonomously. The evolution of selfing is associated with reduced visual floral signalling in many systems, but effects on floral scent have received less attention. We compared mu

Residual stress can be introduced unintentionally into the workpiece with various magnitudes and distributions through all manufacturing processes. These stresses have a significant effect upon the performance of the final component. Understanding the residual stress imparted by machining is an essential aspect of understanding the machining process and overall part quality. Although many investig

Objective: Little is known about midlife risk factors of future cardiac arrest. Our objective was to evaluate cardiovascular risk factors in midlife in relation to the risk of cardiac arrest (CA) of cardiac and non-cardiac origin later in life. Methods: We cross-matched individuals of the population based Malmö Diet and Cancer study (n = 30,447) with the local CA registry of the city of Malmö. Bas

This thesis consists of four independent empirical papers on monetary policy and economic inequality. The first paper explores the Romer and Romer (R&R) (2004) framework to estimate monetary policy shocks. R&R propose a simple method to estimate shocks using forecast and real-time data, but such data is not always available. We study the consequences of using revised outcome data when esti

ConspectusBy combining results and analysis from cylindrical microjet photoelectron spectroscopy (cMJ-PES) and theoretical simulations, we unravel the microscopic properties of ethanol-water solutions with respect to structure and intermolecular bonding patterns following the full concentration scale from 0 to 100% ethanol content. In particular, we highlight the salient differences between bulk a

The upper elevational limits of vegetation growth in global high-mountains have been the focus for monitoring and assessment of climate change impacts on terrestrial ecosystems. However, existing studies have relied on field surveys that do not allow for large-scale analysis. Although remote sensing data have been used for local and regional monitoring of the vegetation upper boundaries, a global

Background: Energy citizenship has emerged as a concept which attempts to capture the new role envisaged for urban citizens as engaged and active in the energy transition. However, exactly how to successfully engage energy citizens requires more research and this article aims to contribute to this knowledge gap. The article presents a new methodology, ‘Walking with Energy’, which seeks to (re)conn

Selection of the number and which of multisource precipitation datasets is crucially important for precipitation fusion. Considering the effects of different inputs, this study proposes a new framework based on the Bayesian model averaging (BMA) algorithm to integrate precipitation information from gauge-based analysis CPC, reanalysis-derived dataset ERA5, and satellite-retrieval products IMERG-E

Aircraft collisions with birds span the entire history of human aviation, including fatal collisions during some of the first powered human flights. Much effort has been expended to reduce such collisions, but increased knowledge about bird movements and species occurrence could dramatically improve decision support and proactive measures to reduce them. Migratory movements of birds pose a unique,

Strålbehandling är en av de vanligaste metoderna för att behandla cancer. I den mest använda formen av strålbehandling används en strålkälla utanför kroppen, så kallad extern strålterapi. Ett alternativ är att ge behandlingen med hjälp av ett läkemedel till vilket man har kopplat ett radioaktivt ämne, så kallad radionuklidterapi. Det radioaktiva läkemedlet ansamlas i tumören och ger där en intern In radionuclide therapy (RNT), radioactive pharmaceuticals are administered for therapeutic purposes. Dosimetry, i.e. the estimation of the absorbed dose to various targets, can potentially lead to a better understanding of the therapeutic effects in RNT and allow for individualization of the therapy. However, dosimetry is seldom used in RNT clinical practice, and several problems degrade the info

With the triumph of the codex, medieval literature became more deeply hermeneutic in character. A vast range of texts, in various languages and genres, were not only copied with the commentaries and glosses of ancient tradition, but also underwent continuous reworking and transformation. Indeed, the very act of transcribing texts into a manuscript was often an incentive to rewrite them. This pract

ABSTRACT: BACKGROUND: Bone grafts are frequently used in orthopaedic surgery. Graft remodelling is advantageous but can occur too quickly, and premature bone resorption might lead to decreased mechanical integrity of the graft. Bisphosphonates delay osteoclastic bone resorption but may also impair formation of new bone. We hypothesize that these effects are dose dependent. In the present study

Introduction: Developing a national assistive products list is an important part of an assistive technology policy and requires knowledge of total population need, and product costs and benefits; information is not always readily available in low-income countries. Our experience in Tajikistan of developing a national assistive products list provides guidance for others. Methods: Two hundred people

The present work details a study of the 3D-modeling of dual-fuel engines, with a specific focus on medium speed marine engines. These operate under the fumigated approach, which means that the second fuel, which replaces most of the diesel fuel, is added in the intake duct. This type of engine requires the least amount of modifications to the current medium speed diesel engine and is therefore an
