Bacterial Adaptive Responses - Coping with Oxygen Limitation, Reactive Nitrogen Species and Disulfide Stress

Bacteria have a remarkable ability to adapt to different environments. When bacteria encounter stress that causes macromolecular damage in the cell, leading to a suboptimal performance of cell metabolism, they can elicit an adaptive response. In this thesis Bacillus subtilis is used as the primary model organism to study bacterial adaptation to oxygen limitation, reactive nitrogen species and disu

Bridging the islands of consciousness : on street art’s potential to affect our perception of public space

For the “Street Art, the City and the Public: Changing the Urban Vision” session at International Visual Sociology Association conference 2013, I discussed the unsanctioned nature of street art and the way it may influence our perception of public space. Taking as a point of departure George Simmel’s well-known thoughts on the blasé urban resident, I see public space as being dominated by individ

Investigation of the Hyperfine Structure of Te 125 in the 5p^(3)6s^(5)S_(2) Level of the Te I Spectrum by Optical Double Resonance and Level Crossing Spectroscopy

Using an enriched sample in a high temperature scattering cell we have determined the hyperfine structure of Te 125 in the 5 p 3 6 s 5 S 2 level of the Te I spectrum by the optical double resonance and level crossing techniques. For the magnetic dipole interaction constant a we obtain | a (5 p 3 6 s 5 S 2 Te 125 )| = 1 010.4 (1.3) MHz The spin density at the nucleus, calculated using this value, i

Distributed averaging on digital noisy networks

We consider a class of distributed algorithms for computing arithmetic averages (average consensus) over net- works of agents connected through digital noisy broadcast channels. Our algorithms combine error-correcting codes with the classical linear consensus iterative algorithm, and do not require the agents to have knowledge of the global network structure. We improve the performance by introduc
