Armored Geomembrane Cover Engineering

Armored Geomembrane Cover Engineering

Geomembranes are an important component of modern engineered barriers to prevent the infiltration of stormwater and runoff into contaminated soil and rock as well as waste containment facilities--a function generally described as a geomembrane cover. This paper presents a case history involving a novel implementation of a geomembrane cover system. Due to this novelty, the design engineers neede...

Modeling sediment pulses on an armored channel

Dams trap sediments in the upstream reservoir, thus the continuity in sediment transport along the river is interrupted. Several negative aspects related to the lack of sediment supply were observed downstream many dams and the artificial replenishment of sediment was applied as a method to restore natural morphological conditions. The replenishment technique may be seen as a pulse of sediments...

Ossified chronic subdural hematoma with armored brain.

Ossified chronic subdural hematoma is a very rarely seen entity. We present here a 22-year-old male who had presented with severe headache consequent to brain compression caused by bifronto-parieto-temporal ossified subdural hematoma. We evaluated our method and surgical intervention in the light of the literature. The question whether the ossified membrane should be excised or not excised in t...

How Do High School Mathematics Texts Cover Engineering and Technology?

The recently developed National Science Education Standards (NSES) and Principles and Standards for School Mathematics (PSSM) promote scientific and mathematical literacy for all students. Further, NSES recommends that an engineering component is an important part of scientific literacy. In previous papers, obstacles to the fulfillment of these goals were considered. One work reviewed science t...
