A Semi-Lagrangian Method for a Fokker-Planck Equation Describing Fiber Dynamics

A simplified Fokker-Planck model for the lay-down of fibers on a conveyor belt in the production process of nonwovens is investigated. It takes into account the motion of the fiber under the influence of turbulence. The emphasis in this paper is on the development of a numerical procedure to solve the model. We present a semi-Lagrangian scheme that accurately captures the fiber dynamics and conser

Visualization of the melanosome transfer-inhibition in a mouse epidermal cell co-culture model.

Transfer of melanin-containing melanosomes from melanocytes to neighboring keratinocytes results in skin pigmentation. To provide a more practical method of visualizing melanosomes in melanocytes as well as in keratinocytes, we attempted to use murine cell lines instead of human primary cells. We generated various fluorescent fusion proteins of tyrosinase, a melanin synthesis enzyme located in the

Maktdimensionen i omsorgsrelationer

Bakgrund: Vårdbiträdet och den äldre formar tillsammans en dynamik i sitt sociala samspel. Här presenteras resultat från en avhandling om omsorgsrelationer i hemtjänsten. Metod: Djupintervjuer av äldre och vårdbiträden; fallstudier kring biståndsärenden med hjälp av deltagande observation av den äldres och vårdbiträdets samspel samt av samspelet i vårdbiträdets arbetsgrupp. Resultat: Det är van
