To escape competition at the dung pile, a ball-rolling dung beetle forms a piece of dung into a ball and rolls it away. To ensure an their efficient escape from the dung pile, the beetles rely on a celestial compass to move along a straight paths. Here, we analyzed the reliability of different skylight cues for this compass and found that dung beetles rely not only on the sun, but also on the skyl
Genome wide association studies (GWAS) identify susceptibility loci for complex traits, but do not identify particular genes of interest. Integration of functional and network information may help in overcoming this limitation and identifying new susceptibility loci. Using GWAS and comorbidity data, we present a network-based approach to predict candidate genes for lipid and lipoprotein traits. We
We propose a novel Bayesian network tool to model the probabilistic relations between a set of type 2 diabetes risk factors. The tool can be used for probabilistic reasoning and for imputation of missing values among risk factors. The Bayesian network is learnt from a joint training set of three European population studies. Tested on an independent patient set, the network is shown to be competiti
Understanding, monitoring and mitigating drought is a very difficult task as a consequence of the intrinsic nature of the phenomenon. In addition, assessing the impact of drought on ecosystems and societies is also a complex task, because the same drought severity may have different consequences in different regions and systems due to the underlying vulnerabilities. New technologies based on geosp
To report contemporary outcomes, and evaluate differences after thrombolysis for occluded endoprosthesis, bypasses and native artery occlusion in patients with lower limb ischemia.
CONTEXT: Prior research suggests that drug abuse (DA) is strongly influenced by both genetic and familial environmental factors. No large-scale adoption study has previously attempted to verify and integrate these findings. OBJECTIVE: To determine how genetic and environmental factors contribute to the risk for DA. DESIGN: Follow-up in 9 public databases (1961-2009) of adopted children and their
This master thesis presents a qualitative model for performing a due diligence analysis of non- financial risks and their management, the DANFiRM model. The model includes a thinking process and a working procedure for identifying and evaluating the current non-financial risk exposure at the target enterprise and further required measures for altering risk exposure and risk management activities t
Metals play a key role as a cornerstone of our modern society; they are part of the most basic elements of our daily life and have been part of our lifestyles for millennia. Current trends of metal production point out that developing countries in order to attain a developed-countries consumption level will require 3-9 times the present metal stock per capita, yet their mining practices are far fr
Countries around the world are employing renewable energy policies to increase renewable electricity in their electricity mix. Trinidad and Tobago (T&T), located in the Caribbean, has endogenous sources of oil and natural gas and has not yet capitalised on sources of renewable energy. The country‟s electricity is currently dominantly generated from natural gas however the natural gas reserves
Aim: To describe the experiences of peer learning in psychiatric inpatient settings during clinical placement of undergraduate nursing students and to highlight the possibility for peer learning in psychiatric outpatient settings. Design: A qualitative inductive design. Method: Questionnaires with 14 students and 12 preceptors in inpatient and outpatient care and interviews with one student and on
The paper presents research results from the Marie Skłodowska-Curie Innovative Training Network INFRASTAR in the field of reliability approaches for decision-making for wind turbines and bridges. This paper addresses the application of Bayesian decision analysis for installation of heating systems in wind turbine blades in cases where an ice detection system is already installed in order to allow
Decision analysis is often used to help decision makers choose among alternatives, based on the expected utility associated to each alternative as function of its consequences and potential impacts. Environmental impacts are not always among the prioritized concerns of traditional decision making. This has fostered the development of several environmental problems and is nowadays a reason of conce
Även om man redan under 1930- och 40 talen förstod att små vattendroppar under vissa förutsättningar kan förbättra släckeffektiviteten för vatten jämfört med större vattendroppar och slutna vattenstrålar, så var det inte förrän på 1990 talet som tekniken med fasta system med ”vattendimma” kommersialiserades. Incitamentet var i första hand det så kallade Montrealprotokollet och branden ombord på pModern, commercial water mist fire protection system technology evolved at the beginning of the 1990s due a need to replace halon fire-extinguishing systems and improve fire safety on passenger ships. This thesis documents the unknown water mist system development work by two Swedish companies during the 1970s and 1980s. It also documents the development of the first international installation rec
This report presents an integrated simulation-based approach to study the on-site production of concrete frameworks by considering the multiple effects of weather on work task productivity and concrete curing process. The suggested approach enable to systematically study how different weather conditions and the use of climate-improved concrete in combination with different methods to shield concre
The Hyogo and Sendai frameworks stress that risk assessments should inform plans. However, it is unclear how, in theory, risk assessments and plans are conceptually related and how, in practice, they inform each other. This study aims to fill this knowledge gap. Conceptually, it proposes an explicit link between risk assessments and plans via the capability of the responding organisation and its e
Different scientific communities produce different kinds of datasets that rely on different data descriptions, approaches, and logical organisations. In such an environment, it is essential to establish a knowledge communication framework that can guarantee some fundamentals, such as an inclusive description and documentation of the interdisciplinary digital resources, their long-term preservation
Deoxyribonucleoside triphosphates (dNTPs) are vital for the biosynthesis and repair of DNA. Their cellular concentration peaks during the S phase of the cell cycle. In non-proliferating cells, dNTP concentrations are low, making their reliable quantification from tissue samples of heterogeneous cellular composition challenging. Partly because of this, the current knowledge related to the regulatio
