the aim of this work was to investigate the influence of interactions between modified starch (hi-cap 100) and the nonionic surfactant tween 80 on the properties of cardamom oil-in-water emulsion and its corresponding spray dried microcapsules. to this end the mean diameter and size distribution of droplets as well as their polydispersity index and also the viscosity and flow behavior of emulsi...

No prior research has documented the different types of rock coatings in Yosemite Valley, despite the evident black streaks down Yosemite Falls, the light granitic rock exposed by recent rock falls contrasting with dark rock coatings, and the millions of visitors who have photographed the coated rocks of Yosemite. This paper identifies the types of rock coatings found on Half Dome, in Yosemite ...

Mudstone is the most common cap rock in petroliferous basins. The mechanical properties of mudstone different areas and buried depths are obviously different, which directly affects brittleness ductileness caprock its deformation characteristic. This research carried out X ray diffraction (XRD) mineral composition analysis, microscopic observation structural characteristics mechanics triaxial c...

Introduction: We have completed analysis of a new near-field rock count at the Mars Pathfinder landing site and determined that the previously published [1,2] rock count suggesting 16 % cumulative fractional area (CFA) covered by rocks is incorrect. The earlier value is not so much wrong (our new CFA is 20%), as right for the wrong reason: both the old and the new CFA’s are consistent with remo...

Abstract. We use 25 new measurements of in situ produced cosmogenic 26Al and 10Be river sand, paired with estimates dissolved load flux water, to characterize the processes pace landscape change central Cuba. Long-term erosion rates inferred from concentrations quartz extracted Cuban sand range 3.4–189 Mg km−2 yr−1 (mean 59, median 45). Dissolved loads (10–176 yr−1; mean 92, 97), calculated str...

Many of the large number underground works constructed or under construction in recent years are unfavorable terrains facing unusual situations and conditions. This is case subject study this paper: a tunnel excavated evaporitic rocks that experienced significant karstification problems very quickly over time. As result situation, causes may underlie rapid investigated novel methodology present...

Original scientific paper Rock burst is a common serious geological hazard in underground engineering, which seriously affects the progress of projects. The mechanism of rock burst can be explained by the distribution law of rock fragments and its fractal characteristics. A simulation experiment of rock burst was conducted with the granite samples under a biaxial loading machine system to analy...
