Thrombin-induced endothelial monolayer hyperpermeability is thought to result from increased F-actin stress fiber-related contractile tension, a process regulated by the small GTP-binding protein Rho. We tested whether this process was dependent on the Rho-associated protein kinase, ROCK, using a specific ROCK inhibitor, Y-27632. The effects of Y-27632 on thrombin-induced myosin light chain pho...

The stability of a rock slope depends on the rock mass geo-structure and its discontinuities. Discontinuities show up at the rock surface as smooth and often plane surfaces. From their location and orientation the main families of fractures can be inferred and a stability analysis performed. To gather information on their distribution, surveys are typically carried out with geological compass a...

A digital imaging technique is used to characterize pore-scale structures and to predict fluid flow at the scale. Heterogeneity at the pore-scale can be assessed by the micro-Computed Tomography (micro-CT), which provides complicated boundary conditions of porous media, and it can also be identified by the numerical flow simulation using the lattice-Boltzmann method (LBM) on the digital image. ...

Interactive systems have been used successfully in sports to assist people in achieving their performance goals, however, we believe that some aspects are often overlooked. In this paper we focus on rock climbing and we examine existing work on climbing from varying fields, including sports science, psychology, and climbing literary works, in order to identify recurring motivational themes. In ...

This research aimed to determine the role of physics teachers in digital learning. Library methods were used and this discussion is based on expert opinions results previous The teacher’s task design, implement, evaluate During current times, teachers, including face far more complex challenges when compared era. Teachers are faced with technological advances, diverse learners, subject matter. ...

In this paper we present an Alife-platform named Urdar aimed at investigating dynamics of ecosystems where species engage in cross-feeding, i.e. where metabolites are passed from one species to the next in a process of sequential degradation. This type of interactions are commonly found in microbial ecosystems such as bacterial consortia degrading complex compounds. We have studied this phenome...
