Abstract in Spanish El objetivo de este trabajo es reflexionar acerca de las diferentes estrategias de desarrollo que, desde la década de 1990, se vienen construyendo en territorios rurales del norte de Argentina. Para ello, presentamos desde una perspectiva comparativa tres casos de estudio localizados en el noroeste y nordeste del país: la Quebrada de Humahuaca (Jujuy), el departamento de San Ca

Three-particle Bose-Einstein correlations - a sensitive probe for Lund string fragmentation

I discuss how a difference in the correlation length longitudinally and transversely with respect to the jet axis in e+e- annihilation, arises naturally in a model for Bose-Einstein correlations based on the Lund string picture. This difference is, due to the longitudinal stretching of the field, more apparent in genuine three-particle correlations. They can therefore be used as a sensitive probe

Low Power Techniques for Fast CMOS Buffer Memories

The thesis deals with circuit-level aspects of CMOS buffer SRAMs where the data throughput rate is a more important metric than access time or storage capacity. One aspect is the increased write cycle related power consumption that is the consequence of a high write ratio combined with a long word-length. That is addressed through the invention of a new bit-line operation mode which allows lower

Public administration developments in post-Soviet Central Asia

In the West, everybody is now talking about the economic and financial crisis. The term ‘’crisis” has become a buzzword within both academic and policy communities. There is an enormous upsurge of scholarly interest in the effects of this crisis on public administration systems, and the role that public administration plays in these processes. The underlying belief is that the public administratio

Forward scattering properties of periodic metamaterials

Forward scattering measurements of periodic metamaterials are investigated. A sum rule for forward scattering is derived using the optical theorem and analytic properties of Herglotz functions. It shows that the absorbed and scattered power over all wavelengths from a periodic metamaterial is related to the static polarizability per unit cell. The theoretical results are verified by a parallel pla

Improving initial xylose metabolism in recombinant Saccharomyces cerevisiae

The aim of the thesis is to improve the initial steps of xylose metabolism in recombinant Saccharomyces cerevisiae. S. cerevisiae takes up xylose of poor affinity by means of hexose transporters. Metabolic control analysis was used to investigate whether the low xylose utilisation rate is due to inefficient transport. Xylose transport was found to have little control over the aerobic xylose utili
