Simulation of Oil Production from Homogenous North Sea Reservoirs with Inflow Control using OLGA/Rocx
Advances in drilling technology have made long, horizontal wells the preferred method to extract oil from reservoirs in the Norwegian Sector. Early water or gas breakthrough is a passive inflow control devices (ICD) are installed to even out the drawdown. However, a new technology called Autonomous Inflow Control Valve (AICV©) has the ability to autonomously close each individual inflow zone in the event of gas or water breakthrough. The objective of this paper was to study and compare these inflow control technologies. This was accomplished by conducting simulations in OLGA/Rocx. For this study, a high-permeability homogenous sandstone heavy oil reservoir was modelled based on data from the Grane oil field in the North Sea. Comparison of the oil production from the simulations with ICD and AICV completion was performed. The results, based on a time interval of 600 days, show that the oil production is 8% less and the water production is 43% less if AICV is used compared to ICD. This indicates that AICV has the potential to reduce the water production significantly in a homogeneous reservoir
Assessment of benefits and risks of probiotics in processed cereal-based baby foods Lactobacillus paracasei ssp. paracasei F19
Source at https://vkm.no/The Norwegian Scientific Committee for Food Safety (VKM) has appointed an ad hoc-group of experts to answer a request from the Norwegian Food Safety Authority regarding benefit and risk assessment of Lactobacillus paracasei ssp. paracasei F19 (F19) in processed cereal-based baby foods intended for small children 1-3 years. This assessment is based on the literature provided by the notifier as well as that found by a MEDLINE search.Vitenskapskomiteen for mattrygghet (VKM) har på oppdrag fra Mattilsynet utarbeidet en nytte- og risikovurdering av Lactobacillus paracasei ssp. paracasei F19 (F19) tilsatt i barnegrøt til barn i alderen 1-3 år. For å besvare oppdraget nedsatte VKM en ad hoc-gruppe. Vurderingen er basert på gjennomgang av litteratur tilsendt fra virksomheten og MEDLINE litteratursøk
Benefit and risk assessment of breastmilk for infant health in Norway: Opinion of the Steering Committee of the Norwegian Scientific Committee for Food Safety
Source at https://vkm.no/english/riskassessments/allpublications/benefitandriskassessmentofbreastmilkforinfanthealthinnorway.4.27ef9ca915e07938c3b2a6df.html.Breastmilk covers all the nutritional needs of the infant the first months of life, with the exception of vitamin D. In addition, breastmilk has a number of protective properties. However, as humans are exposed to polluting chemicals through food, air, water and skin contact, breastmilk also contains contaminants. Taking the present-day levels of contaminants in Norwegian breastmilk and the long duration of breastfeeding (12 months) in Norway into account, the Norwegian Scientific Committee for Food Safety concludes that contaminants poses a low risk to Norwegian infants, and that the benefits of breastmilk to Norwegian infants clearly outweigh the risk presented by contaminants

Mortality and microbial diversity after allogenic hematopoietic stem cell transplantation: secondary analysis of a randomized nutritional intervention trial
Gut mucosal barrier injury is common following allogeneic hematopoietic stem cell transplantation (allo-HSCT) and associated with poor clinical outcomes. Diet is critical for microbial diversity, but whether nutritional support affects microbiota and outcome after allo-HSCT is unknown. We present a secondary analysis of a randomized controlled nutritional intervention trial during allo-HSCT. We investigated if the intervention influenced gut microbiota, short-chain fatty acids (SCFAs), and markers of gut barrier functions, and if these parameters were associated with clinical outcomes. Fecal specimens were available from 47 recipients, and subjected to 16S rRNA gene sequencing. We found no significant differences between the intervention group and controls in investigated parameters. We observed a major depletion of microbiota, SCFAs, and altered markers of gut barrier function from baseline to 3 weeks post-transplant. One-year mortality was significantly higher in patients with lower diversity at 3 weeks post-HSCT, but not related to diversity at baseline. The relative abundance of Blautia genus at 3 weeks was higher in survivors. Fecal propionic acid was associated with survival. Markers of gut barrier functions were less strongly associated with clinical outcomes. Possibly, other strategies than dietary intervention are needed to prevent negative effects of gut microbiota and clinical outcomes after allo-HSCT
