Influence of clouds on the spectral actinic flux density in the lower troposphere (INSPECTRO): overview of the field campaigns
2008
Ultraviolet radiation is the key factor driving tropospheric photochemistry. It is strongly modulated by clouds and aerosols. A quantitative understanding of the radiation field and its effect on photochemistry is thus only possible with a detailed knowledge of the interaction between clouds and radiation. The overall objective of the project INSPECTRO was the characterization of the three-dimensional actinic radiation field under cloudy conditions. This was achieved during two measurement campaigns in Norfolk (East Anglia, UK) and Lower Bavaria (Germany) combining space-based, aircraft and ground-based measurements as well as simulations with the one-dimensional radiation transfer model UV…
General overview: European Integrated project on Aerosol Cloud Climate and Air Quality interactions (EUCAARI)-integrating aerosol research from nano …
2011
In this paper we describe and summarize the main achievements of the European Aerosol Cloud Climate and Air Quality Interactions project (EUCAARI). EUCAARI started on 1 January 2007 and ended on 31 December 2010 leaving a rich legacy including: (a) a comprehensive database with a year of observations of the physical, chemical and optical properties of aerosol particles over Europe, (b) comprehensive aerosol measurements in four developing countries, (c) a database of airborne measurements of aerosols and clouds over Europe during May 2008, (d) comprehensive modeling tools to study aerosol processes fron nano to global scale and their effects on climate and air quality. In addition a new Pan…
Porous aerosol in degassing plumes of Mt. Etna and Mt. Stromboli
2016
Abstract. Aerosols of the volcanic degassing plumes from Mt. Etna and Mt. Stromboli were probed with in situ instruments on board the Deutsches Zentrum für Luft- und Raumfahrt research aircraft Falcon during the contrail, volcano, and cirrus experiment CONCERT in September 2011. Aerosol properties were analyzed using angular scattering intensities and particle size distributions simultaneously measured with the Polar Nephelometer and the Forward Scattering Spectrometer probes (FSSP series 100 and 300), respectively. Aerosols of degassing plumes are characterized by low values of the asymmetry parameter (between 0.6 and 0.75); the effective diameter was within the range of 1.5–2.8 µm and the…

A Self-Contained Electro-Hydraulic Cylinder: Modeling, Control Design, Simulation and Experimental Validation
2018
Master's thesis Mechatronics MAS500 - University of Agder 2018 In the constant effort to improve the efficiency of hydraulic systems, the pressure drop over hydraulic valves has been one of the major obstacles. In the Self-Contained Electro-Hydraulic Cylinder, the directional valve and the hydraulic power unit have been replaced by a bi-directional axial piston pump and a Permanent Magnet Synchronous Motor. Actuation of the cylinder is performed by controlling the direction of rotation and the velocity of the motor. Originally the purpose of this project was to: "Design a proper control algorithm for an existing novel selfcontained electro-hydraulic cylinder, implement it on the main boom o…
Pathogenesis of primary Sjögren's syndrome beyond B lymphocytes
2020
Primary Sjögren's syndrome (pSS) is a chronic autoimmune disorder affecting exocrine glands of the body, prevalently lacrimal and salivary glands. The pSS pathogenesis has been thought to be B-cell-centric and several clinical trials have been carried out in order to clarify the therapeutic role of B-cell depletion in patients with pSS. Unfortunately, however, B-cell depletion with rituximab has failed in demonstrating any significant results in pSS patients. Besides the contribution of B cells in the pathogenesis of pSS, effector Tfh, Th17 and Th22 cells, follicular dendritic cells (DCs), innate cells (ICs) and several cytokines, chemokines and miRNA have been proved to participate to the …
Work rhythm, flow and success in a project : a case study research
2013
Masteroppgave i økonomi og administrasjon - Universitetet i Agder 2013 Organisations and individuals are shaped and influenced by their environment and interaction with others in a conscious or unconscious manner. Due to increased competitiveness, organisations need to be aware of elements in their environment and how these can affect operations and outcomes. Rhythms in organisations and the employee’s work rhythms are considered to influence flow and the achieved level of success in organisations. This thesis aims to investigate factors setting the work rhythms for organisations and individuals, and to study whether work rhythms influence flow and level of success. Our research question wa…
Endring av organisasjonsstruktur : konsekvenser for bygg- og anleggsprosjekter
2015
Masteroppgave økonomi og administrasjon- Universitetet i Agder, 2015 Denne masteroppgaven er en kvalitativ studie som tar for seg forskningsspørsmålet "Hvordan blir prosjekter i en bygg- og anleggsorganisasjon påvirket av å gå fra matriseorganisasjonsstruktur til linjeorganisasjonsstruktur?". Jernbaneverket har vært benyttet som caseorganisasjon ettersom de i 2014 endret sin organisasjonsstruktur på dette viset. Målet for oppgaven har vært å forstå hvilken betydning organisasjonsstruktur har på gjennomføring av prosjekt, og hvilke konsekvenser en endring har. Dette da organisasjoner i dag har begynt å vende tilbake til den tradisjonelle linjeorganisasjonen. Problemstillingen er særlig gjeld…
Sustainable strategies: Integrating sustainability practices into corporate business operations : How can companies in polluting industries develop a…
2019
Master's thesis Business Administration BE501 - University of Agder 2019 This thesis seeks to study how companies within polluting industries can develop and implement profitable and sustainable business strategies. In order to answer the given research question, the shipping and cruise line industry is the chosen industry of study, due to its air and water pollutions. Research on the field states that the strategic management process of companies within the industry is rather challengingand addresses the need for further studies. The literature identified a gap between the development and implementation phases, with the latter stated as most difficult for the strategic manager. Therefore, …
Norwegian sitt samfunnsansvar : Er Norwegian sitt samfunnsansvar godt forankret i deres organisasjon?
2018
Masteroppgave økonomi og administrasjon BE501 - Universitetet i Agder 2018 Denne oppgaven har til hensikt å undersøke hvor godt forankret samfunnsansvaret til Norwegian er i organisasjonen. Tematikken er relevant fordi viktigheten av organisasjoners samfunnsansvar stadig vokser og Norwegian er en global organisasjon som både har blitt hyllet og høylytt kritisert for deler av sitt samfunnsansvar. Flyselskaper blir av mange oppfattet som verstinger, både når det kommer til miljø og på arbeidsforholdene de ansatte har. Norwegian har vært mye omtalt og er en kjent aktør i media når det kommer til disse forholdene. Organisasjonens miljøsatsing kombinert med ulike konflikter med forskjellige ansa…
