Transcription of the nfrA-ywcH operon from Bacillus subtilis is specifically induced in response to heat.
The NfrA protein, an oxidoreductase from the soil bacterium Bacillus subtilis, is synthesized during the stationary phase and in response to heat. Analysis of promoter mutants revealed that the nfrA gene belongs to the class III heat shock genes in B. subtilis. An approximate 10-fold induction at both the transcriptional and the translational levels was found after thermal upshock. This inducti...
متن کاملDual-beam Wide-band Beamformer with Integrated Antenna Array
As part of the development of a new international radio-telescope SKA (Square Kilometre Array), three phased-array prototypes with increasing complexity have been developed. The final SKA telescope will consist of more than one million receiving antenna elements and will operate in the frequency range of 200 to 2000 MHz. One of the challenges of the next generation radio telescopes for astronom...
متن کاملCmb Observations Using the Ska
We examine the prospects for observations of CMB anisotropy with the SKA; we discuss the advantages of interferometric SKA imaging, observing strategies, calibration issues and the achievable sensitivity. Although the SKA will probably operate at cm wavelengths, where discrete source confusion dominates the CMB anisotropy, its extreme sensitivity to point sources will make it possible to subtra...
متن کاملSensitive Continuum Surveys with the SKA: Goals and Challenges
The system equivalent flux density of the SKA specified by Aeff/Tsys = 12000 m 2 K is S ≈ 0.23 Jy. Given a 25% bandwidth at 1.4 GHz (B ≈ 350 MHz), the noise floor in a total-intensity continuum image should be only σn ≈ 9 nJy beam −1 after τ ≈ 1 megasecond (≈ 280 hours) of integration. However, the sensitivity of SKA images might be limited by systematic errors caused by (1) natural confusion f...
متن کاملOperations and the Properties on Non-First-Normal-Form Relational Databases
In this paper, non first normal form relations (or NFRa) are discussed. First the authors define compoai t ion of tuplea to introduce NFR and discuss some properties. Then canonical forma of NFRa are defined using Vest” operations. This is optimal in the sense that every 1NF relation can be always transformed into canonical ones and canonical forma have the desired properties to some extent. Al...
