Potetkvalitet under lagring: effekt av modningsgrad og ventilasjonsstrategier : studier av lagringssykdommen Fusarium råte

Storage losses of Norwegian potatoes are estimated to approximately 10%. The losses are caused by respiration, transpiration, germination and diseases. These are processes that can be managed by controlling storage conditions and the quality of the potatoes that goes into storage. The main aim of this thesis is to gain knowledge on how to maintain tuber quality and reduce losses during storage, with special emphasis on tuber maturity, ventilation strategies and Fusarium dry rot.Lagring av poteter er nødvendig under norske forhold, men innebærer samtidig en stor fare for tap av verdier og ressurser. Lagringstapene, som i Norge estimeres til 10%, skyldes biologiske prosesser knyttet til respirasjon, transpirasjon, spiring og sykdomsangrep. For å lykkes med lagring er det viktig å ha fokus på råvarekvalitet, slik som potetens modningsgrad og sykdomssmitte, og på lagringsklima. Formålet med denne studien er å bidra med kunnskap som hjelper til med å opprettholde kvaliteten og redusere tapet under lagring. I arbeidet er det særlig fokus på ventilasjonsstrategier, på modning og på Fusarium råte.Foundation for Research Levy on Agricultural Products (FFL) and funding from the Agricultural Agreement (JA), together with Norwegian food industry partners Gartnerhallen AL, Bama Gruppen AS, Findus Norge AS, FellesJuice AS, HOFF SA, Graminor AS, NordGrønt, Norgesgrønt, Maarud AS and KiMs Norge AS

A maximum likelihood estimator of a Markov model for disease activity in Crohn's disease and ulcerative colitis for annually aggregated partial observations.

Crohn's disease (CD) and ulcerative colitis (UC) are chronic inflammatory bowel diseases that have a remitting, relapsing nature. During relapse, they are treated with drugs and surgery. The present study was based on individual data from patients diagnosed with CD or UC at Herlev University Hospital, Copenhagen, Denmark, during 1991 to 1993. The data were aggregated over calendar years; for each year, the number of relapses and the number of surgical operations were recorded. Our aim was to estimate Markov models for disease activity in CD and UC, in terms of relapse and remission, with a cycle length of 1 month. The purpose of these models was to enable evaluation of interventions that would shorten relapses or postpone future relapses. An exact maximum likelihood estimator was developed that disaggregates the yearly observations into monthly transition probabilities between remission and relapse. These probabilities were allowed to be dependent on the time since start of relapse and on the time since start of remission, respectively. The estimator, initially slow, was successfully optimized to shorten the execution time. The estimated disease activity model for CD fits well to observed data and has good face validity. The disease activity model is less suitable for UC due to its transient nature through the presence of curative surgery

Adjunctive dabigatran therapy improves outcome of experimental left-sided <i>Staphylococcus aureus</i> endocarditis

<div><p>Background</p><p><i>Staphylococcus aureus</i> is the most frequent and fatal cause of left-sided infective endocarditis (IE).

Storage diseases is a serious challenge in carrots. Effects on storage quality of studies to loosen soil structure, combined with studies of carrot varieties, carrot age and storage conditions are presented in this paper, intended for Norwegian growers

Consistency and interoperability in a national term bank

In this paper we will describe some problems related to the defini-tion of a set of data categories as well as to the import and merging of data from various resources. First, we illustrate how organizing a taxonomy of data cate-gories is facilitated by using the principles for creating a terminological ontolo-gy (or concept system). Next, we discuss how multiple terminological entries referring to the same concept can be identified with the purpose of merging them
