Crude oil exposures reveal roles for intracellular calcium cycling in haddock craniofacial and cardiac development.
2016
AbstractRecent studies have shown that crude oil exposure affects cardiac development in fish by disrupting excitation-contraction (EC) coupling. We previously found that eggs of Atlantic haddock (Melanogrammus aeglefinus) bind dispersed oil droplets, potentially leading to more profound toxic effects from uptake of polycyclic aromatic hydrocarbons (PAHs). Using lower concentrations of dispersed crude oil (0.7–7 μg/L ∑PAH), here we exposed a broader range of developmental stages over both short and prolonged durations. We quantified effects on cardiac function and morphogenesis, characterized novel craniofacial defects, and examined the expression of genes encoding potential targets underly…
Miljøterapeutteam i barneverntjenesten : Evaluering av miljøterapeutteam i barnevernstjenesten i Kristiansand kommune
2013
Systematisk bruk av miljøterapeutiske tilnærminger til barn og familier i barnevernet anvendes i varierende grad. Miljøterapeutteamet er et hjemmebasert tiltak for familier som er i behov at hjelpetiltak etter lov om barneverntjenester § 4-4. Tiltaket er et førstelinjetilbud i Kristiansand barneverntjeneste. Familiene som teamet arbeider med blir henvist fra barneverntjenestens saksbehandlere. Etter ønske fra ledelsen i barneverntjenesten ble teamet opprettet for å arbeide målrettet inn i familier i en avgrenset periode. Hensikten var å gi målrettede og virkningsfulle hjelpetiltak i en presset situasjon hvor mye tid og ressurser gikk til meldingsgjennomganger, undersøkelser, tiltakssaker og…
Næromsorgsør : En evaluering av et hjemmebasert tiltak for jenter i alderen 14-18 år
2007
Denne rapporten er en beskrivende evaluering av Næromsorg Sør`s arbeid med jenter i alderen 14-18 år. Næromsorg Sør er en privat stiftelse som presenterer seg blant annet som et tiltak som retter fokus på jenter og gutter i alderen 13-18 år, der rus-, psykiatri- eller atferdsproblematikk er utprega, og deres familier. Det er et nærmiljø- /næromsorgstiltak, som også kan være et alternativ til institusjonsplassering. Det jobbes med relasjoner og målet er å skape ny mestringstillit både hos jenta/gutten og familien. Tiltaket benyttes av barneverntjenesten som et hjelpetiltak med hjemmel i Lov om barneverntjenester § 4-4, første ledd. Problemene til jentene som utgjør utvalget i denne undersøke…
Impacts of electricity pricing on techno-economic performance of photovoltaic-battery centered microgrid
2021
The energy management technique in a microgrid, plays very crucial role for making it more economic viable during the electricity energy pricing dynamics. It is vital to investigate the impact of e...
Control strategy based on wavelet transform and neural network for hybrid power system
2013
Published version of an article in the journal: Journal of Applied Mathematics. Also available from the publisher at: http://dx.doi.org/10.1155/2013/375840 Open Access This paper deals with an energy management of a hybrid power generation system. The proposed control strategy for the energy management is based on the combination of wavelet transform and neural network arithmetic. The hybrid system in this paper consists of an emulated wind turbine generator, PV panels, DC and AC loads, lithium ion battery, and super capacitor, which are all connected on a DC bus with unified DC voltage. The control strategy is responsible for compensating the difference between the generated power from the…
Parameter Matching Analysis of Hydraulic Hybrid Excavators Based on Dynamic Programming Algorithm
2013
Published version of an article in the journal: Journal of Applied Mathematics. Also available from the publisher at: http://dx.doi.org/10.1155/2013/615608 Open Access In order to meet the energy saving requirement of the excavator, hybrid excavators are becoming the hot spot for researchers. The initial problem is to match the parameter of each component, because the system is tending to be more complicated due to the introduction of the accumulator. In this paper, firstly, a new architecture is presented which is hydraulic hybrid excavator based on common pressure rail combined switched function (HHES). Secondly, the general principle of dynamic programming algorithm (DPA) is explained. T…
Design and Fabrication of Solar Water Distillation System for Developing Countries
2017
Master's thesis Renewable Energy ENE500 - University of Agder 2017 The local population in Somalia is experiencing a shortage of fresh drinking water due to high salt content in the ground water. The humanitarian organization Yme is a big contributor for providing clean and safe drinking water for local communities. Yme is interested in building an effective water distillation system to improve the water quality and better the health situation in the country. The main goal of this thesis was to contribute to improving water quality by building a solar water distillation system. As the system is meant for local communities in Somalia, the technology should be easy and without modern control …
Energy-saving analysis of hydraulic hybrid excavator based on common pressure rail
2013
Published version of an article in the journal: The Scientific World Journal. Also available from the publisher at: http://dx.doi.org/10.1155/2013/560694 Open Access Energy-saving research of excavators is becoming one hot topic due to the increasing energy crisis and environmental deterioration recently. Hydraulic hybrid excavator based on common pressure rail (HHEC) provides an alternative with electric hybrid excavator because it has high power density and environment friendly and easy to modify based on the existing manufacture process. This paper is focused on the fuel consumption of HHEC and the actuator dynamic response to assure that the new system can save energy without sacrificin…
Installation of offshore wind turbines: A technical review
2021
Abstract The installation phase is a critical stage during the lifecycle of an offshore wind turbine. This paper presents a state-of-the-art review of the technical aspects of offshore wind turbine installation. An overview is first presented introducing the classification of offshore wind turbines, installation vessels, rules and regulations, and numerical modelling tools. Then, various installation methods and concepts for bottom-fixed and floating wind turbines are critically discussed, following the order of wind turbine foundations and components. Applications and challenges of the methods are identified. Finally, future developments in four technical areas are envisioned. This review …
Hva, hvem og hvordan? : håndbok i helse-, miljø- og sikkerhetsarbeid
2003
Alt som skjer innenfor en virksomhet skal tilfredsstille lovfestede og forskriftsmessige krav til tilsattes helse, miljø og sikkerhet (HMS). Dette er et viktig satsningsområde innenfor norsk arbeidsliv, og det er regulert av arbeidsmiljøloven med tilhørende forskrift om internkontroll. Imidlertid er det et langt stykke vei å gå fra bestemmelser i lov og forskrift til et funskjonelt og realistisk HMS-opplegg i den enkelte virksomhet. Denne boken er en slags "loggbok" for eget arbeid og egen bevisstgjøring gjennom de siste 6- 7 års arbeid innen HMS-sektoren ved Høgskolen i Agder.
