The dynamic properties of coarse granular soils have been much less studied than in sands. From a database 14 gravel samples subjected to cyclic triaxial tests, available relationships are and new proposed estimate the normalised shear modulus G/Gmax damping ratio D as function strain γ. effect confining stress, fines content, uniformity coefficient loading frequency on variation G/ Gmax versu...

A three-dimensional fluid dynamics model is developed to capture the spatial complexity of the effects of salmon redds on channel hydraulics, hyporheic exchange, and egg pocket habitat. We use the model to partition the relative influences of redd topography versus altered hydraulic conductivity (winnowing of fines during spawning) on egg pocket conditions for a simulated pool–riffle channel wi...

Visible-near infrared reflectance spectra for five particle size fractions of a Hawaiian palagonite (HWMK101) and a nontronite (ferruginous smectite, Clay Minerals Society source clay SWa-1) were measured under ambient, purged, and heated conditions to characterize the effects of surface and volume scattering on the relationship between absolute H2O content and the strength of the 3 μm absorpti...

utilization of long fiber chemical pulp to enhance the strength properties of mechanical and chemi-mechanical pulp is served as a common approach by the papermakers. therefore softwood long fibers were exposed to chemical modification by cationic agent, eptmac, with the aim of reducing its consumption. then, the cationised fibers were mixed with cmp pulp with given ratios and the handsheets wer...
