We report a case of Demodex infestation in a 35 year old coal miner presenting with a 5 year history of scally papulopustular eruption on his face. He had been working inunderground coal tunnels in a humid- hot- dusty environment and he had been used to bath twice a day with hot water and multiple cleaners. The patient was treated successfully with oral metronidazol, topical permethrin, topical...

Nomenclature, far from being a dry dusty subject, is today more relevant than ever before. Researchers into genomics are discovering again the need for systems of nomenclature-names are what we use to communicate about organisms, and by extension the rest of their biology. Here, we briefly outline the history of the published international codes of nomenclature, tracing them from the time of Li...

We present near-infrared spectroscopy and Hubble Space Telescope (HST) imaging of ERO J164023+4644, an Extremely Red Object (ERO) with (R − K) = 5.9 at z = 1.05 that has been detected by ISO at 15μm. ERO J164023 appears to be a disk galaxy, with an optical/infrared spectral energy distribution which appears to be strongly reddened by dust (Lfir/Lb < ∼ 200; Av ∼ 5). The combination of the narrow...

Context. We present 12.8 μm images of the core of NGC 1068, the archetype Seyfert type II galaxy, obtained during first operations of the BURST mode of the VLT/VISIR (Imager and Spectrometer in the InfraRed at the Very Large Telescope). Aims. We trace structures under the diffraction limit of one UT (Unit Telescope at the VLT) and we investigate the link between dust in the vicinity of the cent...

Wepresent ISO-SWS spectroscopy of the cool dusty envelopes surrounding two Planetary Nebulae with [WC] central stars, BD+30 3639 and He 2-113. The λ < 15 μm region is dominated by a rising continuumwith prominent emission from C-rich dust (PAHs), while the long wavelength part shows narrow solid state features from crystalline silicates. This demonstrates that the chemical composition of both s...

We estimate the star-formation rates and the stellar masses of the Extremely Red Objects (EROs) detected in a ≈ 180 arcmin Ks-band survey (Ks ≈ 20mag). This sample is complemented by sensitive 1.4GHz radio observations (12μJy 1σ rms) and multiwaveband photometric data (UBV RIJ) as part of the Phoenix Deep Survey. For bright K < 19.5mag EROs in this sample (I − K > 4mag; total of 177) we use pho...

We compare observations of AGB stars and predictions of the Elitzur & Ivezić (2001) steadystate radiatively driven dusty wind model. The model results are described by a set of similarity functions of a single independent variable, and imply general scaling relations among the system parameters. We find that the model properly reproduces various correlations among the observed quantities and de...

In this paper, we show how the two-fluid equations describing the evolution of a dust and gas mixture can be re-formulated to describe a single fluid moving with the barycentric velocity of the mixture. This leads to evolution equations for the total density, momentum, the differential velocity between the dust and the gas phases and either the dust-to-gas ratio or the dust fraction. The equati...

Primary features of a new cosmological model, which is based on conjectures about an existence of the graviton background and superstrong gravitational quantum interaction, are considered. An expansion of the universe is impossible in such the model because of deceleration of massive objects by the graviton background, which is similar to the one for the NASA deep space probes Pioneer 10, 11. R...

A s cardiologists know to their cost, the course of coronary artery disease is highly unpredictable. Although the disease accounts for about 20% of all deaths in developed countries and high levels of morbidity, in most cases the disease is clinically silent. Autopsy studies reveal that more than half of all people over the age of 60 and over a quarter of adults under this age have coronary art...
