Abstract: A method for operating a wind turbine having at least one blade includes determining an ambient air operating envelope and controlling a power output of the wind turbine at least partially based on the determined ambient air operating envelope. Determining an ambient air operating envelope includes measuring at least one of an ambient air temperature, an ambient air pressure, an ambient air humidity, and wind turbine power output. The method also includes comparing at least one of a measured ambient air temperature, a measured ambient air humidity and a measured ambient air pressure to predetermined ambient air temperature, pressure and humidity values. The method further includes referencing the predetermined ambient air temperature, pressure and humidity values to at least one operational parameter of the wind turbine. The method also includes determining if an existing wind turbine power output is within a range associated with the determined ambient air operating envelope.

Abstract: A pheromone attractant composition for attracting the green mirid, Creontiades dilutus (St{dot over (a)}l), comprising as the component active in attracting green mirids an effective amount of an admixture of hexyl hexanoate and (E)-2-hexenyl hexanoate.

Abstract: A method of selecting the components of a blend attractive to moth pests, comprising the steps of: (1) measuring the attractiveness of a plurality of single candidate compounds; and (2) selecting for blending those candidate compounds which show statistically significant attraction.

Abstract: This invention relates to a device for suspending a double-ended paddle which is used to propel a small water craft. The device can be readily disassembled and stored and has particular application to kayaks. In the preferred embodiment of the invention the paddle is supported by an elastic member attached at its midpoint. The elastic member depends from a freely swinging overhead boom which projects from a mast mounted to the water craft in front of the paddler. The paddle location and paddle lifting force can be adjusted.
