In pavement design, the CBR and direct shear tests are two very common laboratory investigations for predicting the strength of a subgrade layer. The relationship between the CBR and water content has been commonly presented in analyses, with the result of the direct shear being expressed from the aspect of effective cohesion and the internal friction angle. Even though most natural soil is in...

Most aquatic vertebrates use suction to capture food, relying on rapid expansion of the mouth cavity to accelerate water and food into the mouth. In ray-finned fishes, mouth expansion is both fast and forceful, and therefore requires considerable power. However, the cranial muscles of these fishes are relatively small and may not be able to produce enough power for suction expansion. The axial ...

Applying the Foster, Haltiwanger, and Krizan (2001) decomposition to plant-level manufacturing data from Chile Korea, we find that entry exit of plants account for a larger fraction aggregate productivity growth during periods fast GDP growth. To analyze this relationship, develop model firm based on Hopenhayn (1992). When introduce reforms reduce costs or barriers technology adoption into cali...

The permeability function is one of the key properties in unsaturated soil mechanics and variation parameters water characteristic curve can easily affect matric suction as well infiltration. purpose this research to explore significant effect SWCC on rainfall A gas two phase flow analysis method was conducted investigate influence stable infiltration intensity. Result showed that when saturati...

The cell division cycle of the early sea urchin embryo is basic. Nonetheless, it has control points in common with the yeast and mammalian cell cycles, at START, mitosis ENTRY and mitosis EXIT. Progression through each control point in sea urchins is triggered by transient increases in intracellular free calcium. The Cai transients control cell cycle progression by translational and post-transl...
