A Modified Prill and Hammer Method Used in The Study of Diacetyl Production by Single Strain Lactic Streptococci
… of the research in this paper was to modify the Prill and Hammer (24) method for the determination of diacetyl so that six analyses could be carried out on one apparatus. Some of the factors which influence the production of diacetyl by pure strains of diacetyl producing organisms were …

Hot spots in ammonium nitrate
… as a fertilizer. In both roles it is provided as prills or pellets, approximately spherical and a few millimetres in diameter. The microstructures of several commercially-available AN compositions were investigated using environmental scanning electron microscopy (ESEM) and X-ray microtomography. …

Struvite Recovery From Source-Separated Urine Utilizing Fluidized Bed Technology
… as a slow-release phosphorus based fertilizer (prill), the reactor was loaned to HRSD by the University of British Columbia. A magnesium solution was injected at the bottom of the reactor to facilitate precipitation along with the recycle urine stream and feed urine as shown. Prill production …

A Modified Voges-Proskauer Method of Determining Diacetyl in Dairy Cultures
… a reliable colorimetric test had failed until Prill and Hammer (21) introduced their method in 1938. Other procedures have been introduced since that time, however none has been used as extensively. Some of the tests introduced were direct methods of estimation. These methods usually deleted …

Design of systems for time delayed activated internal release of chemicals in concrete from porous fibers, aggregates of prills, to improve durability
… corrosion tests. Filled fiber, aggregate or prill manufacture, storage, and placement need to be researched and assessed for cost. Design of components using only targeted areas for release in the component and the use of time released fibers in reinforced cement laminates should be evaluated.

Influence of Temperature and Time on Nutrient Release Patterns of Osmocote Plus™, Nutricote™, and Polyon™ Controlled-Release Fertilizers
Polymer-coated controlled-release fertilizers (PCFs) are the most widely used class of fertilizers in the production of container-grown nursery plants. Nutrient release from PCFs is primarily influenced by temperature. The objective of this study was to determine the influences of temperature and …
