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...
ارزیابی ریسک بهداشتی ناشی از فلزات سنگین موجود در ذرات معلق در هوای محوطه دانشگاه علوم پزشکی کردستان
Background and purpose: In recent years, dust storms have affected many regions in Iran including Kurdistan province. Along with dust other pollutants such as heavy metals may also be transferred which pose a risk to human health. The purpose of this study was to determine heavy metals concentrations in atmospheric PM10 in Sanandaj, Iran and also assessing their health risk on the staff and stu...
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...
