Sealing Properties of Bentonite Suspensions*

Sealing with waterborne clays is a rapid and low cost method of controlling seepage through porous media whenever the clay source is within economical shipping distance of the sealing site. But more must be learned about this method of sealing before it can be fully utilized. Water impedance of waterborne bentonites, as measured by water loss in the filter press test, was correlated with their ...

Is Root Catalase a Bifunctional Catalase-Peroxidase?

Plant catalases exhibit spatial and temporal distribution of their activity. Moreover, except from the typical monofunctional catalase, a bifunctional catalase-peroxidase has been reported. The aim of this study was to investigate whether the leaf and root catalases from six different plant species (Lactuca sativa, Cichorium endivia, Apium graveolens, Petroselinum crispum, Lycopersicon esculent...

Catalase Concentration

Brahn (3) observed very low liver catalase ac tivity in human beings who had died as the result of malignant growths. Later work showed that of all the individual liver enzymes studied in can cerous rats and mice the activity of catalase was by far the most affected. Greenstein and co workers (6, 7) have reported that with the pro gressive growth of the tumor there is a decrease in liver catala...

Mechanical Properties of Plastic Concrete Containing Bentonite

Plastic concrete consists of aggregates, cement, water and bentonite, mixed at a high water cement ratio, to produce a ductile material. It is used for creating an impermeable barrier (cut-off wall) for containment of contaminated sites or seepage control in highly permeable dam foundations. The effects of water to binder ratio and clay dosage on mechanical properties of plastic concrete were i...
