Extraction of PCBs and PCDD/Fs from Food and Feed Matrices Using Pressurised Liquid Extraction (PLE)

Since the Belgian dioxin crisis in 1999 there has been a great demand for fast, cheap and reliable methods to analyse food and feed samples. Traditional methods use large amounts of solvent for the extraction, are time demanding and laborious, but new and more sophisticated methods have been developed in recent years. Among these new techniques, pressurised liquid extraction (PLE) is a good altern

Peocolipase and enterostatin- Functions during high-fat feeding

Popular Abstract in Swedish Fetma är ett ökande problem i många delar av världen eftersom det leder till en ökad risk för sjukdomar såsom typ 2 diabetes (åldersdiabetes) och hjärtkärlsjukdomar. Anledningen till att fetma ökar är det stillasittande liv som många lever idag i kombination med en alltför kaloririk kost. Flera studier har visat att ett ökat intag av fett inducerar fetma. Detta kan ha fEnterostatin is a peptide formed in the stomach and intestine during the activation of pancreatic/gastric procolipase. Procolipase is a necessary cofactor for lipase. These two proteins contribute to the breakdown of dietary triglycerides in the intestine. Enterostatin has been found to act as a satiety factor, selectively inhibiting fat intake both through sites in the gastrointestinal tract and

CFD Investigation of Swirl-stabilized Flexi-fuel Burner Using Methane-air Mixture for Gas Turbines

Combustion modeling based on a multi-step global reaction mechanism [1] is applied to CFD (Computational Fluid Dynamics) analysis of a scaled swirl-stabilized 4th generation premixed DLE (Dry Low Emission) burner for gas turbines. The flexi-fuel burner consists of a MAIN premixed flame, a premixed PILOT flame and a confined RPL (Rich Pilot Lean) flame. Both steady-state RANS (Reynolds Averaged Nav

Foretellings of Ragnarök: World-engulfing Asymptotic Giants and the Inheritance of White Dwarfs

The search for planets around white dwarf stars, and evidence for dynamical instability around them in the form of atmospheric pollution and circumstellar disks, raises questions about the nature of planetary systems that can survive the vicissitudes of the asymptotic giant branch (AGB). We study the competing effects, on planets at several AU from the star, of strong tidal forces arising from the

Effect of Cement Type, Silica Fume, Water-cement Ratio, Age and Moderate Shift in Temperature on Self-desiccation in Concrete.

This article outlines an experimental and numerical study on the effect of cement type, silica fume, w/c, age and moderate shift of temperature on self-desiccation and strength of concrete. For this purpose 81 sealed cylinders made of 9 concretes with w/c varying between 0.32 and 0.50, based on two types of Portland Cement, were manufactured. Five per cent silica fume was used in one third of the

Dementia with Lewy bodies - a clinical and neurological approach

Popular Abstract in Swedish Demens med Lewy bodies - en ny demenssjukdom Vid sidan av de klassiska demensformerna Alzheimers sjukdom, blodkärlsdemens och frontallobsdemens har forskargrupper från flera håll i världen på senare år funnit tecken på en ny demensform som man kallar ”demens med Lewy bodies (DLB)”. Sjukdomen bär drag av både Alzheimers och Parkinsons sjukdom och därför är forskare oeniDementia with Lewy bodies (DLB) is a dementia disorder, clinically characterized by fluctuating cognitive impairment, attention deficits, visual hallucinations, parkinsonism and other neuropsychiatric features. Sensitivity to neuroleptic medication is a common finding. In the present study 24% of 200 autopsied cases, within the Lund longitudinal prospective dementia study fulfilled the clinical di
