  1. 1. Models for capturing the penetration of a diffusant concentration into rubber : Numerical analysis and simulation

    Författare :Surendra Nepal; Adrian Muntean; Nadja Ray; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; transport of diffusants; moving-boundary problem; finite element method; a priori and a posteriori error estimates; random walk method; two-scale coupled system; Matematik; Mathematics;

    Sammanfattning : Understanding the transport of diffusants into rubber plays an important role in forecasting the material's durability. In this regard, we study different models, conduct numerical analysis, and present simulation results that predict the evolution of the penetration front of diffusants. LÄS MER

    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicin och hälsovetenskap; Parkinson s disease PD ; Alzheimers disease AD ; Amyloidosis; Alpha synuclein; Amyloid beta;

    Sammanfattning : Alzheimer's disease (AD) and Parkinson's disease (PD) are the most common neurodegenerative diseases in the world. It has been possible to identify common denominators for AD and PD, including aggregation of the amyloid proteins amyloid-beta (Aβ) and alpha-synuclein (α-syn). LÄS MER
