Explosive Volcanism on Atmosphere-less Bodies - a Comparison of the Moon, Mercury and Io
Introduction: There is abundant observational evidence of explosive volcanism on all three of the large airless silicate-dominated bodies, the Moon [1], Mercury [2] and Io [3]. The lack of atmospheres makes analysis of explosive activity relatively simple. We combine the results of earlier analyses of explosive volcanism to draw inferences about the geologic circumstances of explosive activity ...
متن کاملMercury toxicity
Mercury is a metal found in elemental, organic, and inorganic forms in the nature. This substance is present in the composition of earth crust, soil, air, and even in some tissues of plants and sea animals. Each year nearly 3400 tons of mercury compounds are released in the environment, which 95% settle in the soil, 3% in the oceans, and 2% in the atmosphere. Different industrial products li...
متن کاملEvaluating Total Mercury and Methyl Mercury Contents in Canned Tuna Fish of the Persian Gulf
Due to hygienic risks of mercury residues in food and marine originated supplements, measuring total mercury and methyl mercury contents of canned tuna as a highly consumable marine food product is essential. In this study, 40 canned Tuna fish (from Persian Gulf) were collected in 2015 and then flame atomic absorption spectrometer (FAAS) and thermo gas chromatography mass spectrophotometry were...
متن کاملEquation of State for Mercury
An analytical equation of state by Song and Mason is developed to calculate the PVT properties ofmercury. The equation of state is based on the statistical-mechanical perturbation theory of hard convexbodies and can be written as a fifth-order polynomial in the density. There exists three temperaturedependentparameters in the equation of state; the second virial coefficient, an effective molecu...
متن کاملLess is more… (more or less…).
In April 1981 Xerox introduced the Star 8010 workstation, the first commercial system with a Graphical User Interface (GUI) and the first to use the “desktop” metaphor to organize a user’s interactions with the computer. Despite the perception of huge progress, from the perspective of design and usage models, there has been precious little progress in the intervening years. In the tradition of ...
