Miners and oil drillers have used computerized technology to extract small concentrations of materials that would once have been unprofitable.
Molasses was excluded from this pool because it was considered to contain significant concentrations of materials other than sugars.
Concentrations of materials contained in the preparations, as well as expected benefits and potential side-effects, should be studied, standardized, monitored, and accurately labeled.
Sediment samples were freeze dried, combusted using the biological oxidizer, and radioactivity was measured by scintillation counting to determine initial concentrations of materials in the sediments and the homogeneities of their distributions.
It's especially good to see a concentration of material by the activist-artist Skylar Fein, a New Yorker now living in New Orleans, who recently had a small solo show at the Brooklyn Museum.
For efficient and satisfactory operation, the most important parameters, such as air flow rate, concentration of material in the air, rotor speed, wear rate, classification capacity and efficiency, require optimization.
At the upper side of the image a white shape is visible indicating a concentration of material, which could possibly have been caused by the build-up of carbon contamination.
Reducing the amount of process water increases the concentration of material in the process, which could potentially increase both the concentration of sugars liberated and reduce the energy required to heat the water to the reaction temperature.
We therefore hypothesized that a strategy to enhance RNAi by perturbation of anterograde transport and the resulting general accumulation and concentration of material at the ER by Brefeldin A treatment might allow addressing this question more specifically.
