Numerical formulation of sea loads to impermeable nets

A load formulation has been introduced to the Finite Element program AquaSim, where the net is impermeable and water is hence not allowed to pass through the elements belonging to the impermeable net. This paper presents the theory of the load formulation, and presents three case studies where the load model is validated

Improved Quantification of Prostaglandins in Biological Samples by Optimizing Simultaneously the Relationship Eicosanoid/Internal-Standard and Using Liquid Chromatography Tandem Mass Spectrometry

Although a wide variety of articles on quantification of eicosanoids by using internal standards are published every year, little has been done on how much internal standard should be added. This article demonstrates that the application of experimental design enables estimating the interaction eicosanoid/internal-standard and to select confidently an optimal amount of internal standard and a response factor (RF) for the analysis of eicosanoids in a high number of samples, where the amount of sample is limited and the unknown levels of eicosanoids are spanned in a wide range of concentrations. The results revealed that the interaction eicosanoid/internal-standard is an important factor that affects the validity of the RF and subsequently the accuracy of the analysis

Den lokale geotopen - bruken av nærmiljøet i geografiundervisninga i den vidaregåande skulen : med indre Nordfjord som feltområde

Målet med denne oppgåva er å vise korleis eksemplar frå eit lokalt naturmiljø kan innarbeidast som ein del av geografiundervisninga i den vidaregåande skulen. Oppgåva er i hovudsak avgrensa til den naturgeografiske delen av faget. Oppgåva blir innleia med ein kort gjennomgang av den nye læreplanen i geografi som vart innført hausten 2006 som ein del av skulereforma Kunnskapsløftet. Vidare blir det diskutert korleis mennesket lærer, kvifor det er viktig å bruke fleire sansar når ein skal danne seg begrep, og kvifor det er gunstig at denne begrepsdanninga skjer nærmiljøet. Ein sentral del av oppgåva er ein gjennomgang av den naturgeografiske bakgrunnsteorien ekskursjonsleiar bør ha om området før ein legg ut på ekskursjon. Hovudtrekka i landskapsutviklinga i indre Nordfjord blir gjennomgått, både gjennom geologisk- og kvartærgeologisk tid, men òg korleis dagens prosessar påverkar landskapet. På grunnlaget av dette blir det så utarbeida tre forslag til heildagsekskursjonar. Aktuelle lokalitetar blir beskrive og supplert med konkrete arbeidsoppgåver for elevane. For kvar lokalitet blir det vist til dei aktuelle kompetansemåla i læreplanen. Det blir til slutt gjort ei teoretisk vurdering av kor godt dei tre ekskursjonane dekker kompetansemåla i læreplanen. Målet er at oppgåva skal vere til nytte for geografilærarar (og geofaglærarar) både i indre Nordfjord og andre stadar i landet

Dynamic Analysis of Large-Scale Transfer Operations for Liquid Hydrogen

Transfer operations from onshore tanks to ship are a crucial component that needs to be understood and optimized to allow for large-scale seaborne transport of liquid hydrogen (LH2). In this work, we present a dynamic model that includes the main components required for loading operations of LH2. An important aspect for scaling-up is to quantify the effect of heat ingress in the pipelines. We implement a detailed pipeline model that we use to compare different insulation alternatives. Due to the nature of loading operations, the dynamic analysis, control strategy and controller tunings play an important role in the dynamic behaviour of the system. Here, we systematically analyse the dynamic behaviour of the system and develop a control strategy for LH2 loading operations. We implement this control strategy in the simulation model for LH2 loading.

Gjøkparasittisme hos heipiplerke: Noen erfaringer fra Øyerfjellet sesongen 2005

In a mountainous area of Øyerfjellet 17 nests of the Meadow Pipit Anthus pratensis were found during the season of 2005. Five or possibly six of these nests were parasitized by the Common Cuckoo Cuculus canorus, giving a parasitizing rate of 29.4% and 35.3%, respectively. The nests were regularly controlled, and two nests were found deserted by the Meadow Pipit probably during the start of the nesting period, whereas three Cuckoo chicks were hatched. Nearly hatched eggs or newly hatched chicks were found ejected from these three Meadow Pipit nests. When comparing the egg clutches from parasitized nests with unparasitized nests, it was roughly estimated that a mean of 1 ½ Meadow Pipit eggs were missing in the parasitized nests. All the five Cuckoo eggs had a pale brownish colour. When considering this brownish colour, it was suggested that mimicry of the Meadow Pipit eggs and the Cuckoo egg were slightly better in the three nests of completed hatching than in the two nests being deserted. The pattern and markings of the eggs showed good mimicry between eggs of Meadow Pipit and Cuckoo except for the pigment concentration at the broad end of many Meadow Pipit eggs

Dendritic cell populations in patients with self-reported food hypersensitivity

Self-reported hypersensitivity to food is a common condition and many of these patients have indications of intestinal immune activation. Dendritic cells (DCs) are recognized as the most potent antigen-presenting cells involved in both initiating immune responses and maintaining tolerance. The aims of this study were to evaluate the DC populations with their phenotype and T cell stimulatory capacity in patients with food hypersensitivity and to study its relationship with atopic disease. Blood samples from 10 patients with self-reported food hypersensitivity, divided into atopic and nonatopic subgroups, and 10 gender- and age-matched healthy controls were analyzed by flow cytometry using the Miltenyi Blood Dendritic cells kit. Monocyte-derived DCs (moDCs) were evaluated concerning their phenotype and T cell stimulatory capacity. DC populations and cell surface markers were not significantly different between patients and healthy controls, but moDCs from atopic patients expressed significantly more CD38 compared to moDCs from nonatopic patients. Moreover, lipopolysaccharide stimulated moDCs from atopic patients produced significantly more interleukin-10 compared to nonatopic patients. CD38 expression was correlated to total serum immunoglobulin E levels. These findings support the notion of immune activation in some patients with self-reported food hypersensitivity. They need to be confirmed in a larger cohort
