Abstract: A method is provided for evaluating a protected plant having a protection mechanism. A population of immature insects (i.e., larvae or nymphs) belonging to an insect species having a plurality of instars is first exposed to the protected plant such that the protected plant is at least contacted thereby.  The insect exposure extends for a selected time period corresponding to a sublethal exposure of the insect population to the protected plant. The exposure of the insect population to the protected plant is then halted following the selected time period and insects collected. A physical characteristic of at least some collected insects is measured and the immature insects are then sorted into instars. The measured physical characteristics are then statistically analyzed across the instars so as to determine an efficacy of the protection mechanism of the protected plant with respect to the insect population. Associated methods are also provided.

Granted: 2011-06-21
Abstract: Il s'agit d'un tube dont la rigidité du diamètre intérieur est améliorée. Ce tube comprend une paroi à zone intérieure, zone intermédiaire et zone extérieure. La zone intermédiaire comprend de multiples couches partiellement décalées et recouvertes qui constituent un certain nombre de rayons non radiaux et de vides dépassant de la zone intérieure et de la zone extérieure. Les rayons non radiaux du tube facilitent la transmission du couple, de la zone intérieure à la zone extérieure, lors des opérations d'enroulement et de manutention, en isolant le diamètre intérieur de la pression radiale exercée sur la zone extérieure. Les rayons et les vides peuvent s'étendre principalement sur toute la circonférence du tube, et donc assurer des propriétés plus sûres à tout le tube.

Abstract: Mixing small amounts of an inorganic halide, such as NaCl, to basic copper carbonate followed by calcination at a temperature sufficient to decompose the carbonate results in a significant improvement in resistance to reduction of the resulting copper oxide. The introduction of the halide can be also achieved during the precipitation of the carbonate precursor. These reduction resistant copper oxides can be in the form of composites with alumina and are especially useful for purification of gas or liquid streams containing hydrogen or other reducing agents.

Abstract: Cette invention concerne un procédé et un dispositif permettant d'ajuster une période de rétroaction d'un indicateur de la qualité de canal (CQI) afin d'augmenter la capacité de la liaison montante dans un système de communication sans fil. La capacité de la liaison montante est augmentée par réduction des interférences sur la liaison montante provoquées par les transmissions de l'indicateur de la qualité de canal. Une unité sans fil d'émission-réception (WTRU) contrôle l'état des transmissions en liaison descendante vers l'unité WTRU et elle fixe la période de rétroaction de l'indicateur CQI sur la base de l'état de ces transmissions en liaison descendante. Une station de base contrôle les besoins des transmissions en liaison montante et en liaison descendante. La station de base détermine la période de rétroaction de l'indicateur CQI d'au moins une unité WTRU sur la base des besoins en liaison montante et en liaison descendante puis elle envoie une commande à l'unité WTRU afin de modifier la période de rétroaction de l'indicateur CQI de l'unité WTRU.

Abstract: A vehicle 1000 is equipped with a fuel cell system 100 and a secondary battery as power sources. A water level of water present on a water-covered road surface is measured by a water level sensor 72. When the measured water level reaches or exceeds a preset threshold value, drive control of the vehicle 1000 stops power generation by a fuel cell stack 10, closes a discharge valve 62, and enables the vehicle 1000 to be driven with output power of a motor that is actuated with electric power from the secondary battery. This arrangement effectively prevents a damage or failure of the fuel cells mounted on the vehicle moving on the water-covered road.

Abstract: A reciprocating compressor or pump features a manifold arranged not only to define a hollow interior for receiving fluid discharged from a plurality of cylinders but also to define a base or frame on which the cylinders are carried. Unique valves formed in part by flexible material reduces the likelihood of fatigue and increases efficiency by retaining less heat relative to conventional reed valves. A compressor or pump mounted at an end of a handle extending parallel to a motor housing likewise extending from the compressor or pump provides an easy to carry portable assembly. A fan mounted between a motor and a compressor pulls air through the compressor inlet to both cool the motor and feed the compressor. A portable tool system powers both pneumatic and electric tools. Connecting rod structures for radial compressors or pumps provide improved strength and easier assembly.

Abstract: Afin de traiter un signal de sous-bande d'une pluralité de signaux de sous-bande réels qui sont une représentation d'un signal temporel discret réel créé par une banque de filtres d'analyse, on utilise un pondérateur (10) destiné à pondérer un signal de sous-bande selon un facteur de pondération déterminé pour le signal de sous-bande, ceci de manière à obtenir un signal de sous-bande pondéré (11). En outre, un terme de correction est calculé par un dispositif de détermination de terme de correction (12), le dispositif de détermination de terme de correction étant mis en oeuvre pour calculer le terme de correction par utilistion d'au moins un autre signal de sous-bande et d'un autre facteur de pondération donné pour l'autre signal de sous-bande, les deux facteurs de pondération étant différents l'un de l'autre. Le terme de correction est ensuite combiné au signal de sous-bande pondéré pour obtenir un signal de sous-bande corrigé, ce qui se traduit par une réduction du repliement, même si les signaux de sous-bande sont pondérés à un degré différent.

Abstract: When the temperature of an engine (ENG) and a main battery (B1) is low at the time of activating a vehicle system, an ECU (40) starts the engine (ENG) in advance and outputs a running permission signal after completion of engine startup. At this stage, the ECU (40) suspends a defect diagnosis operation on a subsidiary load (60) and feedback-controls the DC/DC converter (30) by setting the voltage control value to a level lower than the output voltage from the subsidiary battery (B2) and at least the lower limit of the operating voltage of the ECU (40). The ECU (40) feedback-controls the DC/DC converter (30) by setting the voltage control value to a level of at least the output voltage of the subsidiary battery (B2) in response to completion of engine start-up.  Then, the suspension of the defect diagnosis operation on the subsidiary load (60) is canceled and a running permission signal is output.
