11. Child nutrition in rural Nicaragua : Population-based studies in a transitional society
Sammanfattning : Emerging favourable as well as unfavourable nutrition patterns are observed in societies undergoing rapid social and economic change. The aim of this thesis is to analyse the associations between household and maternal resources and infant and young child feeding habits and nutritional status in rural Nicaragua, a low-income transitional society.

12. Transitional and turbulent flow in porous media
Sammanfattning : Fluid flow through porous media takes place in many natural processes such as ground water flows, capillary flows in plants and flow in human organs and muscles. It is also of outmost importance to have knowledge of this flow in a number of industrial processes such as paper making, making of fibre boards, composites manufacturing, filtering, forming and sintering of iron ore pellets and drying and impregnation of wood.

13. Nonlinear dynamics in transitional wall-bounded flows
Sammanfattning : This thesis focuses on numerical studies of subcritical transition to turbulence in shear flows. The thesis employs a framework based on nonlinear dynamics in the subsequent studies. The geometrical approach to subcritical transition pivots the concepts of edge manifold and edge state. LÄS MER

15. Modelling and control of turbulent and transitional flows
Sammanfattning : The dynamics of fluid motion can accurately be described by the Navier– Stokes equations. Manipulating these equations to reduce their complexity but preserving their main characteristics has always been a key research activity in the field of fluid mechanics. LÄS MER
