Nytt og nyttig, men er det nyttiggjort? : erfaring med implementering av Lifecare eRom i kommuner
2016
Masteroppgave i helse- og sosialinformatikk- Universitetet i Agder, 2016 We are both working in a municipality where a nursing home has procured Lifecare eRom, which is a module in the electronic medical record solution Gerica. The purpose of eRom is to provide quick access to a patient’s treatment plan, as well as the possibility to create documentation on touch screens site in the patient’s room. After six months we found that the system was not in use. Furthermore, we were under the impression that there had been some challenges with the implementation. Based on this, we formulated the following issue for exploration: What success factors and barriers have municipalities experienced duri…
Implementing an institutional change in a regional context : A case study of telemedicine implementation and diffusion in Agder
2018
Master's thesis Information Systems IS501 - University of Agder 2018 High life expectancy, aging population and an increasing chronic diseases generates new challenges for the current global healthcare (Brouard, Bardo, Vignot, Bonnet, & Vignot, 2014). Public agencies and business corporates have shown interest inadvances technological research and innovation projects to remedy the problem. Innovating in public sector is highly challengingand results shouldn’t be taken for granted (Dacin, Goodstein, & Scott, 2002). Further, there is a lack of understanding how public innovations are created (Sørensen & Torfing, 2011). Theoretically the thesis builds on two strands of theories: institutional …

Aerosol- and updraft-limited regimes of cloud droplet formation: Influence of particle number, size and hygroscopicity on the activation of cloud con…
2009
We have investigated the formation of cloud droplets under pyro-convective conditions using a cloud parcel model with detailed spectral microphysics and with the κ-Köhler model approach for efficient and realistic description of the cloud condensation nucleus (CCN) activity of aerosol particles. Assuming a typical biomass burning aerosol size distribution (accumulation mode centred at 120 nm), we have calculated initial cloud droplet number concentrations (<i>N<sub>CD</sub></i>) for a wide range of updraft velocities (<i>w</i>=0.25–20 m s<sup>&minus;1</sup>) and aerosol particle number concentrations (<i>N<sub>CN</sub><…
Suppression of new particle formation from monoterpene oxidation by NOx
2014
The impact of nitrogen oxides (NOx = NO + NO2) on new particle formation (NPF) and on photochemical ozone production from real plant volatile organic compound (BVOC) emissions was studied in a laboratory setup. At high NOx conditions ([BVOC] / [NOx] x] > 23 ppb) new particle formation was suppressed. Instead, photochemical ozone formation was observed resulting in higher hydroxyl radical (OH) and lower nitrogen monoxide (NO) concentrations. When [NO] was reduced back to levels below 1 ppb by OH reactions, NPF was observed. Adding high amounts of NOx caused NPF to be slowed by orders of magnitude compared to analogous experiments at low NOx conditions ([NOx] ~300 ppt), although OH concentrat…
Towards automatic calibration of 2-D flood propagation models
2010
Abstract. Hydraulic models for flood propagation description are an essential tool in many fields and are used, for example, for flood hazard and risk assessments, evaluation of flood control measures, etc. Nowadays there are many models of different complexity regarding the mathematical foundation and spatial dimensions available, and most of them are comparatively easy to operate due to sophisticated tools for model setup and control. However, the calibration of these models is still underdeveloped in contrast to other models like e.g. hydrological models or models used in ecosystem analysis. This has two primary reasons: first, lack of relevant data against which the models can be calibr…
Bunker Cave stalagmites: an archive for central European Holocene climate variability
2012
Holocene climate was characterised by variability on multi-centennial to multi-decadal time scales. In central Europe, these fluctuations were most pronounced during winter. Here we present a record of past winter climate variability for the last 10.8 ka based on four speleothems from Bunker Cave, western Germany. Due to its central European location, the cave site is particularly well suited to record changes in precipitation and temperature in response to changes in the North Atlantic realm. We present high-resolution records of &delta;<sup>18</sup>O, &delta;<sup>13</sup>C values and Mg/Ca ratios. Changes in the Mg/Ca ratio are attributed to past meteoric p…
Simulating stress-dependent fluid flow in a fractured core sample using real-time X-ray CT data
2016
Various geoscientific applications require a fast prediction of fracture permeability for an optimal workflow. Hence, the objective of the current study is to introduce and validate a practical method to characterize and approximate single flow in fractures under different stress conditions by using a core-flooding apparatus, in situ X-ray computed tomography (CT) scans and a finite-volume method solving the Navier–Stokes–Brinkman equations. The permeability of the fractured sandstone sample was measured stepwise during a loading–unloading cycle (0.7 to 22.1 MPa and back) to validate the numerical results. Simultaneously, the pressurized core sample was imaged with a medical X-ray CT scanne…
X-ray CT analyses, models and numerical simulations: a comparison with petrophysical analyses in an experimental CO2 study
2016
An essential part of the collaborative research project H2STORE (hydrogen to store), which is funded by the German government, was a comparison of various analytical methods for characterizing reservoir sandstones from different stratigraphic units. In this context Permian, Triassic and Tertiary reservoir sandstones were analysed. Rock core materials, provided by RWE Gasspeicher GmbH (Dortmund, Germany), GDF Suez E&P Deutschland GmbH (Lingen, Germany), E.ON Gas Storage GmbH (Essen, Germany) and RAG Rohöl-Aufsuchungs Aktiengesellschaft (Vienna, Austria), were processed by different laboratory techniques; thin sections were prepared, rock fragments were crushed and cubes of 1 cm edge leng…
A Conceptual Framework for Using and Evaluating Web-Based Learning Resources in School Education
2010
Published version of an article from the journal:Journal of Information Technology Education. Also available from the publisher: http://www.jite.org/documents/Vol9/JITEv9p053-079Hadjerrouit743.pdf Web-based learning resources (WBLRs) have provided teachers with a wide range of new teachingexperiences that are not possible in traditional classroom. However, little research has beendone as to which approach to WBLRs is suitable to address issues that are pertinent to learning.This paper proposes a conceptual framework to explore the design and evaluation of WBLRs inschool education. The paper also examines the way in which the framework is used to evaluatestudents? and teachers? perceptions o…
