context: in recent years, nanotechnology has opened up several new avenues of extraordinary biomedical potential by modulating metals into their nanosize leading to significant improvement in their chemical, physical and optical properties. introduction: the advanced fabrication techniques have been exploited to modify nanostructured materials. the functionalized nanoscaled fibers display vario...

stabilization of earth slopes with various proposed methods is one of the important concerns of geotechnical engineering. in this practice, despite numerous developments, design conservativeness and high costs of stabilization are the issues yet to be addressed. this paper not only deals with pile location optimization but also studies the effects of the pile length by using line segments slip ...

[Purpose] This study investigated the effect of unstable surface trunk stabilization exercise on the abdominal muscle structure and balance of stroke patients. [Subjects] The subjects were divided into two groups: an unstable surface trunk stabilization exercise group (n=13), and a stable surface trunk stabilization exercise group (n=11). [Methods] Both groups performed trunk stabilization exer...

Surface Stabilization Mechanisms in Metal Oxides Andrés E. Becerra Toledo Metal oxide surfaces play a central role in modern applications, ranging from heterogeneous catalysis to electronic devices, yet little is known about the processes determining their structural stabilization. Several such stabilization mechanisms are explored via a combination of theoretical and experimental methods. The ...

to construct copper heap leaching structures, a stepped heap of ore is placed over an isolated sloping surface and then washed with sulphuric acid. the isolated bed of such a heap consists of some natural and geosynthetic layers. shear strength parameters between these layers are low, so they form the possible sliding surfaces of the heaps. economic and environmental considerations call for stu...
