Introduction: The characteristics of Martian soils are a matter of clear importance when considering the problems that can arise for a rover traversing areas where loose particles are predominant – as Opportunity had the mischance to comprove by itself. The study of Martian surficial materials has been the subject of a number of works, mainly concerned with the texture, constitution, origin and...

Mineral fillers can be defined as “inert materials included in a mix design for some useful purpose”. They can be added to compounds in order to complete a large variety of final properties without increasing costs or to improve specific characteristics like hardness, brittleness, impact strength, compressive strength, softening point, fire resistance, surface texture, electrical conductivity, ...

PURPOSE To carry out a radiological and histomorphometric evaluation of bone response to two xenografts of animal origin, one porcine, and the other bovine, inserted in rabbits' tibiae. MATERIAL AND METHODS Twenty New Zealand rabbits weighing 3900-4500 g were used. Twenty bovine bone grafts (Endobon) in granulated form of 500-1000 μm granulometry were inserted in the proximal metaphyseal area...

ABSTRACT Two different sizes of aggregates glass microspheres were compared in suspension with silicone oils viscosities. The concentration the was kept constant and equal to 62 vv.%. rheological behavior suspensions evaluated by squeeze flow test, for two test speeds. For both particles size, when immersed less viscous oil, yield stress did not show a good correlation tests Meanwhile, more oil...

aeolian process and subsequently soil erosion are key factors in dryland environments. such phenomena are related not only to geoecological factors (lithology, topography, and climatology) but also to land-use and plant cover changes. formation of new sand dunes in damghan explains the development of human activities over the past. the aim of this study is to explain the land use changes and th...

The study of water bodies such as rivers is an important problem in the remote sensing community. A meaningful set quantitative features reflecting geophysical properties help us better understand formation and evolution rivers. Typically, river sub-basins are analyzed using Cartosat Digital Elevation Models (DEMs), obtained at regular time epochs. One useful a sub-basin that roughness measure ...
