  1. 11. Conséquences d’un stress chronique sur la barrière de mucus intestinal chez le rat : effet du probiotique Lactobacillus farciminis

    Författare :Stéphanie da Silva; Muriel Mercier-Bonin; Annick Bernadier-Donadille; Bruno Pot; Nathalie Juge; France Clermont Ferrand University UMR454 INRA; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Background. Despite a large body of literature incriminating mucus alterations in the pathogenesis of Intestinal Bowel Diseases (IBD), structural and physical changes in the mucus layer remain poorly understood in the micro-inflammatory context of Irritable Bowel Syndrome (IBS).

  3. 12. Cost allocation methods in cooperative transportation planning

    Författare :Joen Dahlberg; Stefan Engevall; Maud Göthe-Lundgren; Jenny Karlsson; Athanasios Migdalas; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Transportation, together with transportation planning for goods, provides good conditions for economic growth and is a natural part of modern society. However, transportation has negative side effects, including emissions and traffic congestion. LÄS MER

  4. 13. Organic Phosphorus Compounds in Aquatic Sediments : Towards Molecular Identification with Mass Spectrometry

    Författare :Heidi De Brabandere; Monica Waldebäck; Emil Rydin; Per J. R. Sjöberg; Rolf Danielsson; William T. Cooper; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; electrospray ionisation; mass spectrometry; liquid chromatography; organic phosphorus; aquatic sediment; eutrophication; sample preparation; extraction; Analytical chemistry; Analytisk kemi;

    Sammanfattning : Phosphorus (P) regulates trophic status in most aquatic systems. However, only bioavailable P contributes to primary production. In most lakes and shallow seas, mineralisation of sediment P into its bioavailable form and its release to the water column is important for maintaining primary production. LÄS MER

  5. 14. Toward Realistic Failure Evaluations for Concrete Buttress Dams

    Författare :Jonas Enzell; Anders Ansell; Erik Nordström; Andreas Sjölander; Richard Malm; Leif Lia; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; concrete dams; buttress dams; stability analysis; dam failure behavior; physical model tests; FEM; betongdammar; lamelldammar; stabilitetsanalys; dammbrott; fysiska modellförsök; FEM; Betongbyggnad; Concrete Structures;

    Sammanfattning : Concrete dams, complex structures supporting massive loads, have traditionally been assessed using simplified 2D analytical stability analyses based on the rigid body assumption. Previous studies have shown that 3D behavior, such as the interaction between the monoliths and the valley's geology, can greatly impact the load-bearing capacity of gravity dams but remains largely unexplored in buttress dams.

  7. 15. Studies of α-synuclein Oligomers-with Relevance to Lewy Body Disorders

    Författare :Therese Fagerqvist; Martin Ingelsson; Joakim Bergström; Lars Lannfelt; Michael G Schlossmacher; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Alpha-synuclein; Parkinson´s disease; Lewy body dementia; Oligomer; Monoclonal antibody; Immunotherapy; Reactive aldehydes; Medical Science; Medicinsk vetenskap;

    Sammanfattning : The protein alpha-synuclein (α-synuclein) accumulates in the brain in disorders such as Parkinson’s disease (PD) and dementia with Lewy bodies (DLB). It is believed that the monomeric form of α-synuclein can adopt a partially folded structure and start to aggregate and form intermediately sized oligomers or protofibrils. LÄS MER
