Wood modification with furfuryl alcohol is an extensively investigated process and already produced commercially. Furfurylated wood is in the focus of a European project on its use for the production of high performance windows. Different wood species were treated with furfuryl alcohol and tested on water uptake, dimensional changes, leaching in water, resistance to fungal degradation, and ecotoxicity. The results show a reduced water uptake and a reduced swelling of the furfurylated wood samples. A high resistance against fungal attack of the treated wood samples can be shown. A low amount of furfuryl alcohol was leached out and the water samples of two different leaching tests showed in general low toxicity. Southern yellow pine showed good results in all of the tests and has potential for the production of window frames according to the tests performed.

Verdiskapingsprogrammet for mat ble igangsatt for å øke verdiskapingen basert på norske matressurser. Etter hvert har programmet fått hele leveringskjeden fra jord til butikk som virkeområde, men siktemålet er stadig å skape positive lønnsomhetseffekter for primærprodusentene. Våre resultater sannsynliggjør at det er positive lønnsomhetseffekter av tiltaket, og at bøndene er relativt mer fornøyd med lønnsomhetseffektene enn andre støttemottagere. Innenfor programmet foregår det et eget nettverksprogram som skal styrke kompetansen i matsektoren. Også dette virkemidlet får klart positiv vurdering fra deltagerne, men tiltaket er for lite til å kunne identifisere målbare lønnsomhetseffekter. Det er viktig for måloppnåelsen ved utviklingsprosjekter at primærprodusentene er med i prosjektene. Resultatene tilsier bl.a. sterkere vektlegging av primærprodusenter og samarbeid med primærleddet i prosjektvurderingen.

Measuring logistics costs for individual products or product groups is a significant challenge. One frequently applied method is Activity Based Costing approach where costs are allocated to products according to the resources and cost they induce. The Norwegian project Woodflow has been working on measuring time consumption for logistics processes for wood products such as lumber, beams, claddings, panels and moulds. Low degree of standardisation within and between manufacturers makes it problematic to convert time and performance measures from one unit of measurement to others. Logistics costs are difficult to allocate to products and are in commonly presented for the complete material flow. The existing data could not be used for calculation of logistics costs for wood products. Different methods have been used to measure time and resources for the processes in the supply chain. Even if the process is correctly measured, it is still be a challenge to allocate costs to products, for example when a carrier contains a large number of different products. The performance measures presented have been developed for Optimera AS, a vertically integrated distributor of construction products. The company owns several distribution centres and more than 70 stores in Norway. A test of the measurements will be conducted in a small part of the distribution system. The logistics costs of supplying the stores from the distribution centre will be compared with directly transporting the lumber from the supplier to the retail outlets.

Many consumers perceive lamb meat from mountain pastures to be of superior quality, a quality that may be altered if lambs are kept for a longer period on cultivated pastures before slaughtering. The objective of this experiment was to compare sensory profile and fatty acid composition in meat from lambs slaughtered directly from unimproved mountain pastures with meat from lambs raised on unimproved mountain pastures and fattened on biodiverse cultivated pastures for 26, 39 and 42 days before slaughtering. The experiment was conducted at two different locations in Norway in 2006 and 2007, with a total of 124 Norwegian Crossbred Sheep lambs. Loin samples of M. Longissimus dorsi from lambs above a body weight of 40 kg were selected and analysed for sensory attributes. Fatty acid composition was determined in the subcutaneous fat over the Longissimus dorsi. Small but significant differences were found in hardness, tenderness, fattiness, metallic and rancid flavour, and in polyunsaturated fatty acids. This indicates that to a small extent pre-slaughter fattening on cultivated pastures alters meat characteristics. (C) 2009 Elsevier Ltd. All rights reserved.

In this study we aimed at understanding the mechanisms that affects an epidemic development of Neozygites floridana in a Tetranychus urticae population. This was done by comparing how many spores a cadaver infected with a N. floridana isolate could produce and at what distance and in which directions they could be thrown on a coverslip at temperatures relevant to the northern hemisphere (13, 18 and 23oC). The highest number of spores were produced at 13oC at a number of 1886. Numbers of spores thrown at 18oC and 23oC were 1733 and 1302 respectively. Temperature had a significant effect on sporulation. Most of the spores were thrown at a distance of 0-0.6 mm from the cadaver. Cadavers placed on the underside of a coverslip were able to throw spores back up on the coverslip surface. A whole plant bioassay was also conducted to reveal where on a plant T. urticae infected with N. floridana die and sporulate. Cadavers showed a different verical distribution on the cucumber plant compared to healthy spider mites. Most of the cadavers were located at the lower to the middle part of the plant, while healthy spider mites were more evenly distributed on the whole plant.

Det foregår en historisk stor satsning for å øke kunnskapen om hjorten og hjortens areabruk i Norge. For tida er det flere regionale prosjekter som undersøker hjortens arealbruk med bruk av GPS halsbånd. Det foregår også et forskningsprosjekt som samler og setter de regionale prosjektdataene inn i en større sammenheng. Vi håper på et "kvantesprang" i kunnskapen om hjorten i åra som kommer!
