Introduction: Lunar domes are smooth low features similar to low terrestrial shield volcanoes. They were formed during the terminal phases of lunar eruptions and mostly occur in the maria. A few domes have been reported in the highlands, but these are usually difficult to observe because of the brightness and ruggedness of the surrounding terrain. According to [1,2], constructional volcanic fea...

[1] The two large low shear velocity provinces (LLSVPs) at the base of the lower mantle are prominent features in all shear wave tomography models. Various lines of evidence suggest that the LLSVPs are thermochemical and are stable on the order of hundreds of million years. Hot spots and large igneous province eruption sites tend to cluster around the edges of LLSVPs. With 3‐D global spherical ...

PURPOSE In the present study, we coined the term 'alveolar dome' and aimed to demonstrate the prevalence of alveolar domes through digital periapical radiographs. MATERIALS AND METHODS This study examined 800 digital periapical radiographs in regard to the presence of alveolar domes. The periapical radiographs were acquired by a digital system using a photostimulable phosphor (PSP) plate. The...

[1] Clusters and coalesced complexes of domes represent a relatively rare landform within the extensive, low-relief, lunar maria. While they are typically spectroscopically similar to mare basalts emplaced by high-volume, low-viscosity eruptions, the large-scale morphology of the domes is more consistent with slower emplacement and/or more viscous magma. We use new Earth-based radar data to stu...

We study Hamiltonian unfolding—cutting a convex polyhedron along a Hamiltonian path of edges to unfold it without overlap—of two classes of polyhedra. Such unfoldings could be implemented by a single zipper, so they are also known as zipper edge unfoldings. First we consider domes, which are simple convex polyhedra. We find a family of domes whose graphs are Hamiltonian, yet any Hamiltonian unf...

Fifteen cypress domes located within an extensively managed slash pine plantation were characterized according to the presence and nature of ditches and berms. Mean water depth and hydroperiod for the year 1978-79 were generally greater in the domes without these alterations. Cypress importance values were significantly higher in the unaltered, wet domes whereas hardwood importance values and s...

in order to investigate the structural behaviour of persian brick masonry domes, three types of semi-circular, (drop, ordinary and raised) four-centred and (drop, ordinary and raised) pointed domes have been studied. the three-dimensional non-linear finite element method using the ansys code has been used for analysis. domes with different thicknesses and spans have been subjected to monotonic ...

Introduction: Mud volcanoes provide a unique low-temperature window into the Earth’s subsurface – including the deep biosphere – and may prove to be significant sources of atmospheric methane. The identification of analogous features on Mars would provide an important new class of sites for geological and astrobiological exploration. We report new work suggesting that features in Acidalia Plani...
