Evaluation of gastric processing and duodenal digestion of starch in six cereal meals on the associated glycaemic response using an adult fasted dynamic gastric model
(Journal article; Peer reviewed, 2013-03)Purpose: To identify the key parameters involved in cereal starch digestion and associated glycaemic response by the utilisation of a dynamic gastro-duodenal digestion model. Methods: Potential plasma glucose loading curves ... -
Rapid photosynthetic recovery of a snow-covered feather moss and Peltigera lichen during sub-Arctic midwinter warming
(Journal article; Peer reviewed, 2013-03-06)Background: Arctic lichens and mosses are covered by snow for more than half the year and are generally considered as being dormant for most of this period. However, enhanced frequency of winter warming events due to climate ... -
Effects of nano-sized zero-valent iron (nZVI) on DDT degradation in soil and its toxicity to collembola and ostracods
(Journal article; Peer reviewed, 2013-06)Nano-sized zero valent iron (nZVI) has been studied for in situ remediation of contaminated soil and ground water. However, little is known about its effects on organisms in soil and aquatic ecosystems. In this study, the ... -
Fatty acid composition,fat-soluble vitamin concentrations and oxidative stability in bovine milk produced on two pastures with different botanical composition
(Journal article; Peer reviewed, 2013-06)Previous research has shown that grazing pastures compared to feeding preserved forages has large impact on milk fatty acid (FA) composition, but differences between grazing red clover (Trifolium pratense L.) or white ... -
Grønt partnerskap i landskapsforvaltning – erfaringer fra prosjektet "Utvalgte kulturlandskap i jordbruket"
(Journal article; Peer reviewed, 2013-06-17)Å ta vare på landskap som omfatter både natur- og kulturminnekvaliteter, leve- og næringsområder er spesielt utfordrende. Det nasjonale prosjektet «Utvalgte kulturlandskap i jordbruket», som, i samarbeid med Direktoratet ... -
Effects of nano-sized zero-valent iron on DDT degradation and residual toxicity in soil: a column experiment
(Journal article; Peer reviewed, 2013-07)Background and aims Nanoscale zero-valent iron (nZVI) application is a promising technology for degradation of chlorinated contaminants in soil. Plants also play an important role in soil remediation and nZVI should not ... -
Systems analysis of field and laboratory experiments considering impacts of CO2 leakage in terrestrial systems
(Journal article; Peer reviewed, 2013-08-05)Geological CO2 storage will be designed to prevent any CO2 leakage. However, as recognized by the European Commission's (EC) CO2 Storage Directive, a capability is needed to assess leakage impacts, even though leaks are ... -
Simulated CO2 leakage experiment in terrestrial environment: Monitoring and detecting the effect on a cover crop using g p 13C analysis
(Journal article; Peer reviewed, 2013-08-05)Geological CO2 storage will be designed to prevent any CO2 leakage. However, according to precaution principles the impact of any risks, independently from its probability of occurrence, must be studied. Following this ... -
Conifer Stored Resources and Resistance to a Fungus Associated with the Spruce Bark Beetle Ips typographus
(Journal article; Peer reviewed, 2013-08-13)Bark beetles and associated fungi are among the greatest natural threats to conifers worldwide. Conifers have potent defenses, but resistance to beetles and fungal pathogens may be reduced if tree stored resources are ... -
