TL;DR: The degree of PEGylation and the MW of P EG were found to strongly influence DNA condensation of PEI and therefore also affect the biological activity of the PEI-g-PEG/DNA complexes, providing a basis for the rational design of block copolymer gene delivery systems.

TL;DR: In this article, the mean pion multiplicity per wounded nucleon increases approximately linearly with a change of slope starting in the region 15--40 A GeV, and the change from pion suppression with respect to $p+p$ interactions, as observed at low collision energies, to pion enhancement at high energies occurs at about 40A GeV.
Abstract: Measurements of charged pion and kaon production in central Pb+Pb collisions at 40, 80, and 158 A GeV are presented. These are compared with data at lower and higher energies as well as with results from $p+p$ interactions. The mean pion multiplicity per wounded nucleon increases approximately linearly with ${s}_{\mathrm{NN}}^{1/4}$ with a change of slope starting in the region 15--40 A GeV. The change from pion suppression with respect to $p+p$ interactions, as observed at low collision energies, to pion enhancement at high energies occurs at about 40A GeV. A nonmonotonic energy dependence of the ratio of ${K}^{+}$ to ${\ensuremath{\pi}}^{+}$ yields is observed, with a maximum close to 40A GeV and an indication of a nearly constant value at higher energies. The measured dependences may be related to an increase of the entropy production and a decrease of the strangeness to entropy ratio in central Pb+Pb collisions in the low SPS energy range, which is consistent with the hypothesis that a transient state of deconfined matter is created above these energies. Other interpretations of the data are also discussed.

TL;DR: Pipe flow is a prominent example among the shear flows that undergo transition to turbulence without mediation by a linear instability of the laminar profile as discussed by the authors, which can consistently be explained on the assumption that the turbulent state corresponds to a chaotic saddle in state space.
Abstract: Pipe flow is a prominent example among the shear flows that undergo transition to turbulence without mediation by a linear instability of the laminar profile. Experiments on pipe flow, as well as plane Couette and plane Poiseuille flow, show that triggering turbulence depends sensitively on initial conditions, that between the laminar and the turbulent states there exists no intermediate state with simple spatial or temporal characteristics, and that turbulence is not persistent, i.e., it can decay again, if the observation time is long enough. All these features can consistently be explained on the assumption that the turbulent state corresponds to a chaotic saddle in state space. The goal of this review is to explain this concept, summarize the numerical and experimental evidence for pipe flow, and outline the consequences for related flows.

TL;DR: The receptor binding region is delimited to a DNA segment of 152 base pairs that has been shown to be relevant for hormonal induction and partially homologous receptor binding sequences located in this region are identified.
Abstract: Glucocorticoids are known to induce the transcription of integrated proviral mouse mammary tumour virus (MMTV) genes in a variety of cell lines derived from mouse mammary tumours Chimaeric genes in which selectable markers are linked to the long terminal repeat (LTR) region of MMTV can be induced by the synthetic glucocorticoid dexamethasone after introduction into mouse fibroblasts This suggests that the regulatory elements required for hormonal induction are located within the cloned LTR fragments The idea is supported by the observation that glucocorticoid receptors bind to certain cloned fragments of MMTV DNA in vitro Using filter binding studies and monoclonal antibodies to the glucocorticoid receptor we have now delimited the receptor binding region to a DNA segment of 152 base pairs (bp) that has been shown to be relevant for hormonal induction In nuclease protection experiments we have identified partially homologous receptor binding sequences located in this region, all of which share the hexanucleotide 5'-TGTTCT-3'

TL;DR: In this paper, the authors propose that the relationship between identification and turnover will be mediated by job satisfaction as the more specific evaluation of one's task and working conditions, which in turn predicts turnover intentions.
Abstract: The social identity approach is a powerful theoretical framework for the understanding of individuals' behaviour. The main argument is that individuals think and act on behalf of the group they belong to because this group membership adds to their social identity, which partly determines one's self-esteem. In the organizational world, social identity and self-categorization theories state that a strong organizational identification is associated with low turnover intentions. Because identification is the more general perception of shared fate between employee and organization, we propose that the relationship between identification and turnover will be mediated by job satisfaction as the more specific evaluation of one's task and working conditions. In four samples we found organizational identification feeding into job satisfaction, which in turn predicts turnover intentions.
