Prize quarry

dogfish and a total allowable catch of zero for 2010. Scientists had recommended a zero catch for this year as studies suggest the northeast Atlantic population is on the verge of collapse. Catches for cod outside the North Sea, hake, monkfish, sole and whiting have also been agreed at levels higher than those recommended by EU advisors. The Bay of Biscay anchovy fishery is to remain closed but...

Some studies on microbacteria from Iowa dairy products.

Microbacteria have attracted attention because they are among the most heat-resistant, non-sporeforming types of bacteria found in dairy products. As they grow poorly, if at all, at 37 C, they usually were overlooked when the standard plate count procedure called for incubation of the plates for 48 hr at that temperature. However, they form small colonies when incubation temperatures of 32 to 3...

PROPERTIES OF FLOWABLE SELF-COMPACTING SLURRY USING QUARRY BY-PRODUCTS AND PONDED CCPs

This paper reports the properties of two series of flowable self-compacting slurry (SCS). In Series 1, a limestone quarry by-product, fine crushed sand (FCS), and ponded-CCPs were used. For Series 2, standard concrete sand and ponded-CCPs were used. For Series 1, five mixtures and for Series 2, six mixtures of flowable SCS were made. Ponded-CCPs and limestone quarry FCS content of the mixtures ...

Development of a Sphagnum Bog on the Floor of a Sandstone Quarry in Northeastern Quarry in Northeastern Ohio

The vegetation and selected ground water characteristics of Silica Sand Quarry Bog, a pioneer bog forming in an abandoned sandstone quarry, were examined. After 70 years of development the bog mat measures 0.75 km in diameter and contains 35 species of vascular plants and 5 species of Sphagnum. Six species of vascular plants from the bog are on Ohio's rare plant list. The herbaceous layer is th...
