We re-address the classification criterion for extremely red galaxies (ERGs) of Pozzetti & Mannucci (2000 – PM00), which aims to separate, in the Ic − K (or Rc − K) vs. J−K colour–colour diagram, passively evolving, old (> 1 Gyr) stellar populations in a dust-free environment, associated with ellipticals (Es), from dusty starburst galaxies (DSGs), both at 1 < z < 2. We explore a category of obj...

Introduction Plasmas with dust grains are of interest both for the cosmic space as well as for the laboratory plasmas. Examples include cometary environments, planetary rings, the interstellar medium, the Earth’s and other planets magnetospheres [1]. Dust has been found to be a determinant component of rarefied plasmas used in the microelectronic processing industry [2], and it may also be pres...

Structure formation and wave phenomena in moderately coupled dusty plasmas." PhD (Doctor of Philosophy) thesis, ABSTRACT Dusty plasmas, defined as plasmas of ions, electrons, neutrals, and charged micron to sub-micron dust particles, support a rich diversity of physical states. These states (ranging from solids to liquids to gas) are determined by the ratio of the Coulomb potential energy betwe...

This paper highlights some of the history of laboratory experiments in dusty plasmas, beginning with an early unexpected discovery of Langmuir. Although there was a great deal of theoretical work on dusty plasmas long before dedicated laboratory experiments were initiated, the experimental work is catching−up and new discoveries in the laboratory are motivating further theoretical work.

As the data from space missions and laboratories improve, a research domain combining plasmas and charged dust is gaining in prominence. Our solar system provides many natural laboratories such as planetary rings, comet comae and tails, ejecta clouds around moons and asteroids, and Earth’s noctilucent clouds for which to closely study plasma-embedded cosmic dust. One natural laboratory to study...

Raw cotton is brought to the Lancashire spinning mills in tightly compressed bales. The bales are opened and teased out in the cotton-room. The cotton is then conveyed to the blow-room where some of the dirt and short fibres are removed. In the card-room the cotton is combed by the wire teeth of the carding engines and passed through a series of machines called combers,* draw, slubbing, interme...

Charging currents of electrons and ions to a spherical dust grain in a uniform magnetized dusty plasma have been examined. It is found that the external magnetic field reduces the charging currents, thereby decreasing the dust charge fluctuation damping of a low-frequency electrostatic wave in a dusty plasma.

concerns have been raised about the adverse impact of dusty air pollution (dap) on human health. the aim of this study was to find the association between dusty air pollution based on air quality index (aqi) and the risk of allergic diseases in southwestern provinces of iran, with assessing cytokine profiles and lymphocyte immunophenotypes.in this case control study 148 individuals participated...

Real dusty crystals are inhomogeneous due to the presence of external forces. We suggest approximations for calculations of different types of inhomoge-neous DC (chain and DC with a few slabs) in the equilibrium state. The results are in a good agreement with experimental results and can be used as an effective diagnostic method for many dusty systems.
