A practical Bridge Management System has been developed by the author, which is referred to as the Japanese Bridge Management System (J-BMS) for existing concrete bridges. This paper introduces a newly developed bridge management system for the prestressed concrete (PC) bridges (J-BMS PC version) which is integrated with the PC bridge rating expert system (PC-BREX). The proposed system is able ...

Despite evidence that weathering plays a role in forming intertidal, estuarine, and fluvial rock platforms, many publications uncritically refer to “wave-cut” or “stream-cut” rock platforms. The alternative explanations of chemical weathering and physical water erosion of rock platforms have been debated since 1839. Our new approach to this long-standing problem introduces data from fluvial as ...

The geometrical and mechanical properties of non-persistent joints as well the behavior intact rock (rock bridges) are significantly effective in shear strength weakness planes containing joints. Therefore, comprehensive knowledge mechanism both bridges is required to assess planes. In this study, specimens a single rough joint investigated. A novel procedure was used prepare cast embedding (di...

Rock masses generally contain many fissures filled with weak materials. At present, the interaction mechanisms of crack coalescence and seepage in rock are still poorly understood. Therefore, this study conducts systematic laboratory tests on sandstone samples two under hydromechanical coupling conditions. The influences fissures, filling, ligament length, bridge angle strength, fracture patter...

Peroxisome proliferator-activated receptor-γ (PPARγ) and Rho-kinase (ROCK) regulate smooth muscle cell (SMC) proliferation and contribute to vascular remodeling in adult pulmonary hypertension. Whether these pathways interact to contribute to the development of vascular remodeling in persistent pulmonary hypertension of the newborn (PPHN) remains unknown. We hypothesized that ROCK-PPARγ interac...

Today’s, the transportation facilities such as terminals, street, bridge, etc, represent the major investment in highway network. Every year tremendous resources should be invested to maintain these facilities. Among them, the Bridge Management System (B.M.S.) has been necessitated by large imbalance between extensive bridge repair and maintenance needs and limited available budget. So the main...

Rock physics modeling aims to provide a link between rock properties, such as porosity, lithology, and fluid saturation, and elastic attributes, such as velocities or impedances. These models are then used in quantitative seismic interpretation and reservoir characterization. However, most of the geophysical measurements are uncertain; therefore, rock physics equations must be combined with mat...

Rho-associated kinase (ROCK) I mediates signaling from Rho to the actin cytoskeleton. To investigate the in vivo functions of ROCK-I, we generated ROCK-I-deficient mice. Loss of ROCK-I resulted in failure of eyelid closure and closure of the ventral body wall, which gave rise to the eyes open at birth and omphalocele phenotypes in neonates. Most ROCK-I(-/-) mice died soon after birth as a resul...

27 Using projective and objective measures, effects of rock music on emotion were investigated. Sixty students were randomly assigned to three conditions: hard rock, soft rock, and no music. One group listened to hard rock music while taking a projective test with five ink blots and an objective test with an Emotional Assessment Scale (EAS). The same procedure was used for the second group whil...
