16. Nonlinear elliptic problems with boundary blow-up
Sammanfattning : A classical problem in differential geometry is the prescribed curvature problemin a bounded domain, where the task is to conformally deform the Euclidean metric to another complete Riemannian metric with a prescribed curvature function.If this function is negative, the problem is equivalent to solving a nonlinear elliptic partial differential equation with boundary blow-up.

17. Convergence analysis of domain decomposition methods : Nonlinear elliptic and linear parabolic equations
Sammanfattning : Domain decomposition methods are widely used tools for solving partial differential equations in parallel. However, despite their long history, there is a lack of rigorous convergence theory for equations with non-symmetric differential operators. This includes both nonlinear elliptic equations and linear parabolic equations. LÄS MER
18. Hot-wall MOCVD for advanced GaN HEMT structures and improved p-type doping
Sammanfattning : The transition to energy efficient smart grid and wireless communication with improved capacity require the development and optimization of next generation semiconductor technologies and electronic device components. Indium nitride (InN), gallium nitride (GaN) and aluminum nitride (AlN) compounds and their alloys are direct bandgap semiconductors with bandgap energies ranging from 0. LÄS MER
19. P-type ATPases studied by electron microscopy and two-dimensional crystallization
Sammanfattning : Electron microscopy and two-dimensional crystallography have been used to study the molecular structures of the porcine renal Na+,K+-ATPase and the porcine gastric H+,K+-ATPase. In addition, morphological changes have been observed with electron cryomicroscopy from tubulovesicles in porcine gastric mucosae. LÄS MER
20. Spatial control of mRNA stability in yeast
Sammanfattning : The degradation of mRNA is an important modulator of gene expression and the ultimate fate of messenger mRNA. Important steps in the degradation of mRNA include initial shortening of its poly(A) tail followed by the subsequent removal of the m7G cap. These two processes are linked temporally as well as spatially. LÄS MER
