Measurements of the E-region electron density were made with the Saint-Santin incoherent scatter radar during consecutive days in June 1978, March 1979 and December 1980. On the basis of a statistical study, the observations show the presence of a diurnal asymmetry of the electron density, with morning values usually exceeding the afternoon densities by 3-20 percent. Two possible causes of the dissymmetry are examined, the asymmetry in the diurnal variation of the neutral composition, and the effect of nitric oxide. The presence of NO partly converts O2(+) into NO(+) ions and increases the effective recombination rate of the electrons in the afternoon. Numerical simulations assessing the relative importance of the two factors are, in general, in good agreement with the measurements. [less ▲]

A general response-based technique is presented for closed-loop transient stability emergency control. It relies on E-SIME, derived from the hybrid transient stability method, SIME. E-SIME uses real-time information supposed to be furnished by phasor measurement units to predict the stability status of the power system, and, in view of an imminent instability, to design and trigger appropriate countermeasures, while continuing monitoring in order to check their effectiveness or to apply additional ones. Performance of the method in terms of accuracy and rapidity is scrutinized and illustrated on several real-world power system examples. New technical solutions and algorithms for the accurate estimation and prediction of power system quantities most relevant to the method are discussed. The observations from a recent investigation and conclusions that could prove useful for improving further the method are summarized together with some realistic timing considerations. A natural coupling of the two SIME based emergency control techniques: open-loop emergency control and E-SIME, so as to combine their complementary features is also discussed. [less ▲]

HU is a 2x90 residues, dimeric bacterial histone-like protein involved in chromosome compaction and other DNA-related processes. E. coli HU proteins are composed of three forms: two homodimers α2 and β2 (α and β sharing 70% of sequence identity) and one heterodimer (αβ). Dimeric forms relative abundance varies during cell growth and in response to environmental changes, suggesting that each dimer plays different physiological roles. Unlike other HU proteins which melt through a single step (N2<=>2D), E. coli dimers melt according to a two-step mechanism (N2<=>I2<=>2D). The native dimer, N2, melts partially into a dimeric intermediate, I2, which in turn yields the unfolded monomers, D. Circular Dichroism studies indicate that the intermediate, I2, corresponds to an HU dimer having partly lost its a-helices. Here we compared dynamic properties and structural features of E. Coli HU dimers at different temperatures in order to determine the secondary strutural elements still present in the I2 intermediate. Isotopically labelled proteins (15N, 13C) have been used to perform backbone assignment for all dimeric forms using sequential triple-resonance experiments. 15N-HSQC at different temperatures (288-323K) were recorded .Intensity variations and chemical shift perturbations allow the identification of the secondary element lost in the intermediate I2 confirming the high dynamics of arms responsible for protein-DNA interactions and the thermal stability of HTH motif in all dimeric forms.

• OBJECTIVE: Escherichia coli is a microorganism widely used in the industry for the production of recombinant proteins. The performances obtained at the laboratory level are not reproducible at a large scale. Actually, the mixing operation is not efficient enough: gradients of glucose and oxygen appear when operating in fed-batch mode (addition of glucose during the culture). These gradients cause adverse impacts on the production of biomass and recombinant protein. The aim of this work is to use the microbial population as biocaptor of the encoutered stress inside heterogeneous industrial bioreactors to better scale-up and regulate these reactors. • MATERIALS AND METHODS: A plasmid carrying a stress promoter followed by the coding sequence of the Green Fluorescent Protein (GFP) is introduced in the bacterial host (in our case, the strain E. coli K12 will be considered as a model organism). When the cell is submitted to given stress condition, GFP synthesis is induced and accumulated into the cytoplasm, leading to the increase of the cell's fluorescence. Flow cytometry detection is used in order to quantify the fluorescence at the single cell level. Obtained results are frequency histograms of fluorescenceintensity in the microbial population • RESULTS: The rpoS gene is a gene of the general stress response, mainly induced at the entrance to stationary phase (during a lack of glucose). The tracking of the GFP fluorescence linked to the activation / repression of the rpoS promoter gives good results. Indeed, there is appearance of a segregation at the level of the GFP content among the microbial population. The intensity of the segregation, as well as its time of appearance during the culture can be related to the bioreactor mixing efficiency. • CONCLUSION: prpoS::gfp strains can be used as biosensors of the heterogeneity of glucose encountered inside industrial reactors. • POTENTIAL APPLICATIONS & KEY BENEFITS: These strains could be used to validate a fed-batch regulation (addition of glucose) at the industrial level.
