We consider the radiation-hydrodynamical formation of a dusty wall in the circumnuclear regions of the Circinus Seyfert 2 galaxy. We focus on the radiative flux force due to the circumnuclear starburst, the nuclear starburst and the active galactic nucleus (AGN), and analyze the equilibrium configuration and stability of the dusty gas in the circumnuclear regions. The mass distributions used to...

The dusty plasma liquid formed by micro-meter sized particles negatively charged and suspended in a low pressure discharge background is a good candidate to study the generic spatio-temporal dynamical behaviors at the kinetic level through direct optical video-microscopy, because of the sub-mm interparticle spacing and the slow time scale. In this paper, starting from the basic picture of the a...

Dusty phenomena such as regular wind-blown dust, dust storms, and dust devils are the most important, currently active, geological processes on Mars. Electric fields larger than 100 kV/m have been measured in terrestrial dusty phenomena. Theoretical calculations predict that, close to the surface, the bulk electric fields in martian dusty phenomena reach the breakdown value of the isolating pro...

In dc glow discharge dusty plasmas, the formation of dust acoustic waves is a commonly observed phenomenon. Experiments in the dusty plasma experiment device produce naturally occurring dust acoustic waves with frequencies f N 5 to 25 Hz and phase velocities of Vph N 0.5 to 10 cm/s. Through the use of particle image velocimetry techniques, particle motion in the vicinity of the wavefronts is id...

We report the discovery of a rich component of dusty star-forming galaxies contaminating the red-sequence in the supercluster system comprising Abell 901a, 901b and A902 at redshift ∼ 0.17. These galaxies do not fit into the colour-density relation, because their preferred habitat is different from that of regular red-sequence galaxies, which are typically dust-poor, old and passively evolving....

The Biometric is the study of physiological or behavioral characteristics used for the identification of a person. These characteristics of a person include the features like fingerprint, face; hand geometry, voice and iris are known as biometrics. Typical physiological features measured include individual’s fingerprints, retina, face, iris and hand. Typical behavioral features that can be meas...

Silent stores, i.e., stores to memory that write the same value as already stored in that memory location, have been observed to occur frequently. These stores not only create redundant memory transactions, but in a multiprocessor environment result in redundant communication messages. In this paper, we quantify the frequency of such silent stores, in particular temporally silent stores, in typ...

background & aims of the study: recent studies indicated that particulate matter can have the lung irritation, chronic lung diseases, lung tissue, etc. the aim objective of this study was to assess the mortality associated with exposure to pm10 concentrations in ilam, iran, during 2013. materials & methods: pm10 data were taken from ilam's local agency of environment (i-lae). the annual mo...

[1] Atmospheric desert dust is potentially highly sensitive to changes in climate, carbon dioxide and human land use. In this study we use 6 different scenarios of the processes responsible for changes in source areas and explore changes in desert dust loading in pre-industrial and future climates, although all the scenario results are likely to be sensitive to the climate model simulations use...
