The stability analysis of rock slopes is a complex task for the geotechnical engineers due to the complex nature of the rock mass in a tropical climate that often has discontinuities in several forms, and consequently, in several types of slope failures. In this work, a rock mass classification scheme is followed in a tropical environment using the Rock Mass Rating (RMR) and Geological St...

AIM To investigate the effects of mammalian homologue of Drosophila diaphanous-1(mDia1) and Rho-associated coiled-coil-containing protein kinase (ROCK) on the migration and adhesion of dental pulp cells (DPCs). METHODOLOGY Lysophosphatidic acid (LPA) was used to activate Rho signalling. mDia1 and ROCK were inhibited by short interfering RNA and the specific inhibitor, Y-27632, respectively. T...

Shroom (Shrm) proteins are essential regulators of cell shape and tissue morpho-logy during animal development that function by interacting directly with the coiled-coil region of Rho kinase (Rock). The Shrm-Rock interaction is sufficient to direct Rock subcellular localization and the subsequent assembly of contractile actomyosin networks in defined subcellular locales. However, it is unclear ...

The dielectric constant of a partially saturated sandstone varies as a function of the level of water saturation. Experimental data indicate that rock/water interaction, at low saturations, has a large effect on the measured dielectric response. To theoretically predict the dielectric constant of the rock/water/air system, this rock/water interaction must be accounted for by including the effec...

Carving rock by indenting sharp objects into the surface under an impact force has been a favored method of fragmentation for millenia . However, as rock gets harder the lifetime of these sharp tools becomes short and, in a compromise hardened bits of rounder contour have become more common, particularly when driven by mechanical power. To better understand the behavior of these newer generatio...

Purpose. Studying the stress-strain state of rock mass under open pit, taking into account change in open-pit bottom width order to reveal geomechanical and determine safe parameters bridge. Methods. The peculiarities formation transition zone have been studied according methodology using numerical research methods geological strength index (GSI). Using this index, it is possible take fracturin...

During cytokinetic abscission, the endosomal sorting complex required for transport (ESCRT) proteins are recruited to the midbody and direct the severing of the intercellular bridge. In this issue, Christ et al. (2016. J. Cell Biol. http://dx.doi.org/10.1083/jcb.201507009) demonstrate that two separate but redundant pathways exist to recruit ESCRT-III proteins to the midbody.

In a recent paper Borel and Serre proved the theorem: If 8 is a Lie algebra of characteristic 0 and 8 has an automorphism of prime period without fixed points f^O, then 8 is nilpotent.1 In this note we give a proof valid also for characteristic p^O. By the same method we can prove several other similar results on automorphisms and derivations. Our method is based on decompositions of the Lie al...
