background and objectives : zeolite is a group of anionic hydrated aluminosilicates with a tridimensional structure which has great implications in remediation of water, sediment and soil resources. the present research aims at physicochemical investigation, clay mineralogy and micromorphology of soils along rafsanjan-sarcheshmeh lithotoposequence, southeastern iran. materials and methods: the ...

Sand grains are ubiquitous in the Earth’s system, and found different environmental settings globally, but sand itself as a physical object has multiple conflicting meanings with respect to both its agglomeration into landforms such dunes beaches, how dynamics have cultural significance meaning. This study takes transdisciplinary approach towards examining of sand, focusing on spatiotemporal ph...

a tiling of a surface is a decomposition of the surface into pieces, i.e. tiles, which cover it without gaps or overlaps. in this paper some special polygonal tiling of sphere, ellipsoid, cylinder, and torus as the most abundant shapes of fullerenes are investigated.

Marine reserves are becoming progressively more important as anthropogenic impacts continue to increase, but we have little baseline information for most marine environments. In this study, we focus on the Oceanic Shoals Commonwealth Marine Reserve (CMR) in northern Australia, particularly the carbonate banks and terraces of the Sahul Shelf and Van Diemen Rise which have been designated a Key E...

Terrestrial paleoclimate records rely on proxies hosted in alluvial strata whose beds are deposited by unsteady and nonlinear geomorphic processes. It is broadly assumed that this renders the resultant time series of terrestrial paleoclimatic variability noisy and incomplete. We evaluate this assumption using a model of oscillating climate and the precise topographic evolution of an experimenta...

Geomorphosites or special geomorphologic sites are new concepts which have entered tourism literature with anemphasis on special sites. Basically, the goal for discussing such concepts is to identify landforms with specialimportance on understanding the geomorphologic structure of a region and their scientific, ecological, cultural,aesthetic, and economical values. Generally, they are used for ...

This paper describes a method to assess the similarity between digital elevation models (DEM), based on the comparison of the landforms. The method attempts to mimic the one commonly used by human beings, which consists of comparisons among the shapes that a human subject identifies in the landscape. To do so, semantic similarity measurements are applied over a hierarchy of concepts. Our method...
