Weak and weathered rocks are well known for their sensitivity to changes in moisture content. Degrading behavior is common weak with moisture-sensitive mineral components present numerous stability problems. The slake durability a measure of the resistance weakening disintegration rock materials which quantitatively distinguishes durable from non-durable materials. Several material parameters i...

Abstract West Sumatera is a region that has an abundance of natural resources in the form iron sand, one which area Pasia Jambak Beach, Padang. Beach type beach rumps and sandy beaches, grayish-brown sand rough grains on its surface. Iron could be formed due to weathering rocks materials found around coast, such as old ships others. This study aims see rock origin composition magnetic mineral e...

We recently identified a novel human protein kinase, p160 ROCK, as a putative downstream target of the small GTPase Rho. Using the human ROCK cDNA as a probe, we isolated cDNA of two distinct, highly related sequences from mouse libraries. One encoded a mouse counterpart of human ROCK (ROCK-I), and the other encoded a novel ROCK-related kinase (ROCK-II). Like ROCK/ROCK-I, ROCK-II also bound to ...

a r t i c l e i n f o The purpose of this study is to investigate the role of filling materials (e.g., quartz sand and kaolin clay) in the interaction between a P-wave and a rock fracture. The specific fracture stiffness reflects the seismic response of a filled fracture, while the wave transmission coefficient describes P-wave transmission across the filled fracture. A series of experimental t...

Chondroitin sulfate proteoglycan (CSPG) inhibits neurite outgrowth of various neuronal cell types, and CSPG-associated inhibition of neurite outgrowth is mediated by the Rho/ROCK pathway. Mesenchymal stromal/stem cells (MSCs) have the potential to differentiate into neuron-like cells under specific conditions and have been shown to differentiate into neuron-like cells by co-treatment with the R...
