Bioreactors – New Solutions for Old Problems
A major effort has been invested in making bioreactors more efficient. The goal has been achieved in several steps. Firstly, a replacement of the traditional rotation movement by an oscillating up and down movement of stirring discs driven by an electromagnet yields several important advantages. A soft, whole volume movement of the medium results in optimal gas distribution throughout the mediu...
متن کاملAdjustment and Poverty in Asia: Old Solutions and New Problems
This paper analyses how adjustment policies affected the poor in Asian economies, focussing on the period up to 1997. It shows that there was a significant reduction in both private income poverty and social income poverty over the previous thirty years. The adjustment policies of the 1980s led to some episodes of rising poverty, but unlike in other regions, there was no substantial increase in...
متن کاملCoulomb Bound States of Strongly Interacting Photons.
We show that two photons coupled to Rydberg states via electromagnetically induced transparency can interact via an effective Coulomb potential. This interaction gives rise to a continuum of two-body bound states. Within the continuum, metastable bound states are distinguished in analogy with quasibound states tunneling through a potential barrier. We find multiple branches of metastable bound ...
متن کاملCalculation of bound states and resonances in perturbed Coulomb models
We calculate accurate bound states and resonances of two interesting perturbed Coulomb models by means of the Riccati-Padé method. This approach is based on a rational approximation to a modified logarithmic derivative of the eigenfunction and produces sequences of roots of Hankel determinants that converge towards the eigenvalues of the equation.
متن کاملMinimally Invasive Aortic Valve Surgery - New Solutions to Old Problems
Aortic stenosis is the most frequent valvulopathy in the western world and basically affects people over 60 years old. It is currently the most common cause of valve replacement in Europe and North America (Schmitto et al., 2011) and its incidence increases with age. (Lung et al., 2003) 25% of people over 65 suffer sclerosis of the aortic valve which can be detected in image tests such as echoc...
