Substitutional effects of In by Cu in CeIn2
EPJ Web of Conferences, 2014 We have investigated the evolution of the magnetic properties on the Ce(In1−x Cux)2 (0< x ≤ 0.3) series of alloys. The orthorhombic structure of the CeIn2 alloy(Imma)changes into the hexagonal AlB2-type (P6/mmm)for x = 0.05 and, then, into the hexagonal ...

Volcanic eruptions from ghost magma chambers [PDF]
, 2008 Recent studies have proposed that magma reservoirs crystallized to a virtually rigid crystal-mush can be partially remelted by diffusion of hot fluids. We show that for a crystal mush with the composition of a K-trachyte from the Campanian Ignimbrite (CI)

An analytical model for gas overpressure in slug-driven explosions:insights into Strombolian volcanic eruptions [PDF]
, 2012 Strombolian eruptions, common at basaltic volcanoes, are mildly explosive events that are driven by a large bubble of magmatic gas (a slug) rising up the conduit and bursting at the surface.

CO2-crystal wettability in potassic magmas. Implications for eruptive dynamics in light of experimental evidence for heterogeneous nucleation. [PDF]
, 2017 The volatile content in magmas is fundamental for the triggering and style of volcanic eruptions. Carbon dioxide, the second most abundant volatile component in magmas after H2O, is the first to reach saturation upon ascent and depressurization.

Felsic Melt and Gas Mobilization During Magma Solidification: An Experimental Study at 1.1 kbar
Frontiers in Earth Science, 2020 Melt and gas transfer processes are essential to the formation and growth of the Earth’s crust and for sustaining volcanic activity. These processes also play a major role in magma fractionation at shallow depths (<10 km) where magmas stall ...

On the Theory of Left/Right Almost Groups and Hypergroups with their Relevant Enumerations
Mathematics, 2021 This paper presents the study of algebraic structures equipped with the inverted associativity axiom. Initially, the definition of the left and the right almost-groups is introduced and afterwards, the study is focused on the more general structures ...

Ranges of Atmospheric Mass and Composition of Super Earth Exoplanets [PDF]
, 2008 Terrestrial-like exoplanets may obtain atmospheres from three primary sources: Capture of nebular gases, degassing during accretion, and degassing from subsequent tectonic activity.

Eos, Transactions American Geophysical Union, 1991 What are the processes that drive magmatic diversity? How is it that volcanic centers can exist for millions of years erupting a variety of chemical types? What are the means by which large batholithic complexes become assembled? Magmas (silicate melts)differ from other geophysical fluids, such as oceans and atmospheres, in that their physiochemical ...

State Machines and Hypergroups
Mathematics, 2022 State machines are a type of mathematical modeling tool that is commonly used to investigate how a system interacts with its surroundings. The system is thought to be made up of discrete states that change in response to external inputs.
