Controlled-release herbicide formulations have been shown to decrease the leaching potential of several herbicides under laboratory and Ðeld conditions. The utility and efficacy of these formulations may be improved by combining several herbicides and a fertilizer source in a single formulation. The objective of these studies was to develop granular alginate formulations that were composed of a...

The application rates for conventional herbicide formulations are generally greater than the recommended dosage, in order to overcome losses from degradation, leaching, volatilization, and sorption during the time needed for weed control. All these factors have encouraged the development of controlled release formulations (CRFs), which can reduce herbicides levels in the environment since less ...

OBJECTIVE To perform a critical comparison between the Brazilian national essential medicines list (Rename, 2012) with the list of essential medicines for children (LEMC, 2011) of the World Health Organization (WHO), regarding the differences among drugs and formulations listed for children. METHODS The LEMC drugs were classified into four categories: 1) absent in Rename; 2) included in Renam...

Some alternative formulations for transient dynamic response optimization are described and analyzed. A critical review and comparative study of the formulations are presented. The key feature of the formulations is that the state variables, in addition to the real design variables, are treated as independent variables in the optimization process. The state variables include different combinati...
