Development of Test Equipment for Evaluating Hydraulic Conductivity of Permeable Block Pavements

Dynamic Hydraulic Conductivity (Permeability) of Asphalt Pavements

External pressures applied to a saturated pavement pore structure are often dynamic due to the repeated tire loading. Therefore, a dynamic permeability constant is more realistic representation of the response of a pavement pore structure than the Darcy’s permeability. To investigate the unsteady (dynamic) fluid flow in asphalt pavements, a 3D fluid flow model was developed using the lattice Bo...

Comparison Of Hydraulic Conductivity Test Methods for Landfill Clay Liners

Accurately measuring the in situ hydraulic conductivity (permeability) of a clay liner is a major factor in the construction of landfill containment systems. Laboratory and large-scale field test methods are often utilized on test pads constructed prior to placement of the production liner to determine the hydraulic conductivity of the clay. While these test methods provide reliable results, th...

development of different optical methods for determination of glucose using cadmium telluride quantum dots and silver nanoparticles

a simple, rapid and low-cost scanner spectroscopy method for the glucose determination by utilizing glucose oxidase and cdte/tga quantum dots as chromoionophore has been described. the detection was based on the combination of the glucose enzymatic reaction and the quenching effect of h2o2 on the cdte quantum dots (qds) photoluminescence.in this study glucose was determined by utilizing glucose...

effect of oral presentation on development of l2 learners grammar

this experimental study has been conducted to test the effect of oral presentation on the development of l2 learners grammar. but this oral presentation is not merely a deductive instruction of grammatical points, in this presentation two hypotheses of krashen (input and low filter hypotheses), stevicks viewpoints on grammar explanation and correction and widdowsons opinion on limited use of l1...
