On the basis of narrow-band visible and near-infrared imagery as well as high-resolution spectroscopy, we report the discovery of a new LBV-type nebula around the B supergiant HD 168625. We find that it essentially consists of a dusty expanding shell from which seems to emerge a bipolar emission nebula, the whole embedded in a reflection nebulosity. The inner shell is stratified: the continuum emission arises beyond the ionized gas, and is possibly due to scattering of stellar light by large dust grains or to non-equilibrium dust emission. The unexpected presence of unidentified infrared emission bands (UIRs) in the spectrum of this object is also discussed. We finally report the non-detection of a comparable nebula around the nearby LBV HD 168607. [less ▲]

Around the time of the impact of NASA's Deep Impact (DI) mission at comet 9P/Tempel 1, in total 6 telescopes with altogether 7 different instruments, located at the La Silla (LSO) and Paranal (VLT) Observatories of the European Southern Observatory (ESO) in Chile, were used to characterize the dust properties before and after the event. The ejecta cloud expanded at an average speed of about 200 ms[SUP]-1[/SUP]during the first hours after the event. It reached stagnation distance of 25000 km about 3 days after impact. The pre-impact dust jet and fan activity (`porcupine' pattern) remained undisturbed after impact. In our measurements the jet activity can be traced to a few 100 km nucleus distance. In total 9 comastructures are identified which may originate from at least 4 regions of enhanced dust emission on the nucleus - one of this region may in fact be multiple. No obvious signatures of a new active region created by DI are found. The overall dust production during the impact compares to about 5-10 h of normal activity. The global expansion geometry of the DI cloud is compatible with a majority of dust grains in the micron size range. Indications exist for asymmetric brightness and colour distributions of the dust in the ejecta cloud. The dust temperature rose from about 280-290 K before to 330 K one day after the event and fell to pre-impact level the day thereafter. The dust reflected sunlight was found to be linearly polarized at about 7.5% in the visible and near-IR, at constant level within about 4000 km from the nucleus. No circular polarization of the dust is detected. [less ▲]

AIM: To describe the effect of introducing the CISOE-A framework for reporting cervical cytology results, including changes in repeat and referral advice in the Netherlands, on the efficacy of the screening programme. Changes in the distribution of cytological results, the detection rate of cervical intraepithelial neoplasia (CIN) lesions, and the detection rate of squamous cervical carcinoma are reported. METHODS: The results of all gynaecology cytological and histological examinations, as registered in the nationwide database for histopathology and cytopathology (PALGA) from 1990 to 2000, were retrieved from seven laboratories in the greater Amsterdam area. RESULTS: After the introduction of the CISOE-A classification, cytological results with equivocal diagnoses decreased significantly from 11.3% to 2.6%, without an increase in the percentages of moderate dyskaryosis or worse. During the study period, the detection rate of histologically diagnosed high grade CIN lesions increased significantly from 4.1 to 6.4/1000 smears, whereas there was no change in the detection rates of low grade lesions or invasive cervical cancer. CONCLUSIONS: The introduction of the new CISOE-A classification system resulted in a substantial decrease of equivocal results and repeat recommendations, without a decrease in the detection rate of high grade lesions, making the screening programme more efficacious.

One theoretical recommendation to develop sustainable rural tourism is to base its development on local resources. This should embed the tourist activity into the local society, avoid easy relocalization of investment, and help to brand the destination. The Belgian Ardennes is a proximate recreational location for Dutch people. The paper lists the local resources that attract Dutch tourists and the ways in which regional and local authorities deal with this tourist development. Based on key actor interviews and in depth analysis of the promotional material produced both by authorities and commercial companies, the paper underlines the hotchpotch of ways used in selling and consuming the Ardennes. Due to the lack of local entrepreneurship and because the Dutch tourism enterprises have better knowledge of the Dutch market, these enterprises control a huge share of tourism activities in the Ardennes. These Dutch investments change the destination as well as the local identity. Initially, Dutch companies developed a form of tourism based on nature and the rural landscape, but they diversified their activities into non land based tourism (not involving the use of land as in agriculture hors sol) and the ‘disneyfication’ of places. This Belgian case study follows more or less the well known ‘tourist destination life cycle model’, but the originality of the paper is to stress the difficulties posed for authorities to regulate tourism development and to maintain the quality of the destination.

Optically polarized light micrographs of isothermally melt-textured DyBa2Cu307-delta compounds (with 15 wt% Dy203 addition) are presented to show evidence for pattern formation of DyBa2Cu305 particles in DyBa2Cu307-delta grains. Different types of pattern were observed and were understood as arising from the crystal growth mechanism of 123 melt-textured materials. In an appendix, the case of patterns in magnetically textured samples is discussed. [less ▲]

We have synthesized c-axis oriented magnetically melt textured grown DyBa2Cu3O7-y samples at 1035 degrees C under 0.6 T magnetic induction. We discuss the crystal growth mechanism of such 123 melt textured grown superconducting ceramics. A strictly tridimensional model is proposed based on Schmitz et al. model, taking into account the peculiar physical properties reported for such materials. In particular a filamentary one dimensional electron conduction path at the percolation threshold is emphasized. We have used optically polarized ligth microscopy as well as electron microscopy analysis to deduce the growth steps. [less ▲]
