A communication statistic information collection apparatus comprises a unit for searching a flow table for a flow entry corresponding to a searching key, a unit for collecting statistics information for each of flows, a unit for generating a packet for notifying a collector apparatus of stored statistics information, a unit for updating the flow table in accordance with statistics control information shown by a statistics control entry found as a result of searching the flow table, and a unit for generating a sample packet to be transferred to the collect or apparatus at a specified sampling rate in accordance with the statistics control information shown by a specified entry found from the flow table.

A semiconductor optical device such as a laser or semiconductor optical amplifier (SOA) based on an indium phosphide substrate or equivalent buffer layer. The active layer of the device is based on conventional InGaAs(P) alloy, but additionally includes N in order to increase the operating wavelength to greater than 1.5 μm, preferably to a wavelength lying in the C- or L-band. The active layer composition may thus be denoted In1-xGaxAsyNzPp with x≧0.48, y≦1−z−p, z≦0.05, p≧0. The active layer may include a quantum well or multi-quantum wells in which case its thickness is preferably less than the critical thickness for lattice relaxation. In other embodiments the active layer is a “massive” layer with quasi-bulk properties. The active layer may advantageously be under tensile stress, preferably roughly between 1% and 2.2%, to manipulate the light and heavy hole bands. The active layer is typically bounded by barrier layers made of a suitable semiconductor alloy, such as AlInAs or InGaAs(P).

The described invention provides a gel formulation of a composition comprising at least one insecticide in an amount effective to control an insect larval population, an apparatus for autodissmenination of an insecticide for insect management containing (1) a cap component, (2) a cup component, and (3) a mesh component, a method and a system for autodissemination for effectively controlling an insect larval population. Also disclosed is an improvided biphasic autodissemination station for control of undesirable insect populations.

There is disclosed a spray apparatus for holding contents comprising diatomaceous earth and a compressed propellant for propelling the diatomaceous earth. There is also disclosed use of diatomaceous earth to control a population of bedbugs, wherein the diatomaceous earth comprises remains of pennate diatoms. There is also disclosed a method of controlling a population of insects, the method comprising causing a compressed propellant to propel diatomaceous earth on a surface. Method of manufacturing a spray apparatus and methods of preparing diatomaceous earth for use in controlling a population of insects are also disclosed.

A method of controlling target aquatic microorganism pest populations by exposing the target population to an effective amount of an aquacidal compound. The aquacidal compounds are selected from the group consisting of quinones, anthraquinones, naphthalenediones, quinine, warfarin, coumarins, amphotalide, cyclohexadiene-1,4-dione, phenidione, pirdone, sodium rhodizonate, apirulosin and thymoquinone. The method is particularly effective for treating ballast water of ships or other enclosed volumes of water subject to transport between or among geographic areas to control the relocation of plants, toxic bacteria, and animals contained in the water.

Waste-treatment processes are enhanced through generation and introduction of specific biological populations customized to perform or favor specific tasks either during the main process, for the formation or precipitation of certain biological nutrients, or to accomplish solids formation reduction in a post-treatment process. These bacteria may be grown from specialized mixes of activated sludge and waste influent by exposing these materials to controlled environments (e.g., in an off-line treatment area). They may then be returned to the main process to perform certain tasks such as converting particulate cBOD into soluble cBOD for utilization, to reduce high solids yield organisms by supplementing the population characteristics with low yield organism characteristics, to provide biological nutrients or oxygenation assistance, to improve nitrification / denitrification efficiency, or to disfavor filamentous biology such as Norcardia sp.
