Axonal injury due to prostatectomy leads to Wallerian degeneration of the cavernous nerve (CN) and erectile dysfunction (ED). Return of potency is dependent on axonal regeneration and reinnervation of the penis. Following CN injury (CNI), RhoA and Rho-associated protein kinase (ROCK) increase in penile endothelial and smooth muscle cells. Previous studies indicate that nerve regeneration is ham...

Abstract The development and construction of offshore wind farms requires the correct estimation friction that can be mobilised at rock/grout interface. In conventional studies, shear behaviour a joint is usually investigated with laboratory tests under constant normal load/stress (CNL), however, in engineering practice, direct testing stiffness (CNS) has been proved to more realistic assessmen...

Abstract Numerical simulation approaches have been widely applied to study mining induced subsidence, and they are potential methods the flooding uplift for abandoned mines. This paper gives an overview about different numerical simulate by underground mines, including three hydraulic conditions, considering both unconfined confined water conditions. Four basic schemes using 1-dimensional rock ...

Field and laboratory studies have indicated that rock fragments in the topsoil may have a large impact on soil properties, soil quality, hydraulic, hydrological and erosion processes. In most studies, the investigated rock fragments still remain visible at the soil surface and only properties of these visible rock fragments are used for predicting runoff and soil loss. However, there are indica...

Analysis of advanced displacement in construction progress of tunnel excavation with weak surrounding rock is carried out by numerical method and comparison of model test result. In allusion to the problems of regional landslides and extruded large-deformation seriously impacting the stability of rock mass in construction process of large-section tunnel with weak surrounding rock, the elastic-p...

In this paper, a rock fragmentation process is simulated during mechanical cutting of rock using an explicit...

conclusions the pattern of longitudinally increased liver stiffness measurements efficiently supported clinical decisions for individualized management strategies. repeated transient elastography in real-life clinical practice appears to have a practical role in monitoring liver transplanted patients. background liver transplanted patients need close surveillance for early signs of graft diseas...

self-centering pier (scp) has been viewed as a remarkable accomplishment which is able to sustain major lateral loading with reduced structure damage in seismic engineering. stiffness deterioration observed in experiment is vital for the seismic performance of self-centering concrete pier. in this contribution, the associated stiffness deterioration with respect to the structural damage is mode...

The rocks are formed through very complex processes and the complex behaviour of rock masses is dominated by the planes of weaknesses . Rock mass consists of intact rock and discontinuities. Many rocks show strain softening behaviour under loads. In this paper, the constitutive models for intact rocks and rock joints are presented. These form the basis for the development of constitutive models...
