摘要:
A toy vehicle includes a body supporting a pair of rear wheels and a pivotally secured lower jaw portion supporting a pair of front wheels. The vehicle further includes a pair of pivotally secured pincers movable between a rearward or closed position and a forwardly extending or open position. Each pincer is coupled to a gear portion which in turn is coupled to one side of a two-sided gear rack movable within the vehicle body in response to a pivoting actuator. As the actuator is pivoted, the gear rack is driven forwardly or rearwardly to cause pivotal motion of the pincers. A resilient body is secured to the vehicle body and includes a plurality of flexible tubular tentacles which extend from the resilient body and are coupled to each of the pincers. As a result, the toy vehicle is configured in a relatively standard appearance closed position or a monster-like alternate configuration as the actuator is moved between alternative positions.
摘要:
The invention is directed to a method of breeding maize using female plants having a transgene encoding an EPSPS enzyme where the female plants are female reproductively tolerant to treatment with glyphosate but can be made male sterile upon treatment with glyphosate.
摘要:
The invention provides a process to prepare a recombined transgenic Zea mays plant from a transgenic Zea mays plant, wherein the transgene in the recombinant plant has an altered genetic structure relative to the genetic structure of the transgene in the transgenic plant, due to recombination-mediated transgene deletion.
摘要:
An electrically programmable memory cell of a type having a source, a drain, a floating gate and a control gate formed over a face of a semiconductor substrate in which a ring region of material doped similarly to the substrate encloses the source, drain and gates and extends to a surface of the substrate around its length. Drain and source coupling regions of material doped oppositely to the substrate contact the drain and source, respectively, within the ring and extend under the ring to the substrate surface outside of the ring defining drain and source contact regions, respectively. A contact outside the ring to the control gate is provided by a gate coupling region also extending under the ring to a substrate surface on either side thereof. An interconnect couples the floating gate to the gate coupling region. A non-light transmitting, electrically conducting shield extends over the cell contacting the ring region around its periphery at the substrate surface.

Voltage coupling/decoupling devices are provided within DRAM devices for improving the bias sensing of sense amplifiers and thus the refresh performance. The voltage coupling/decoupling devices couple or decouple bias voltage from corresponding digit lines coupled to the sense amplifiers. By coupling and decoupling voltage from the digit lines, the time interval between refresh operations can be increased.

The disclosed discovery relates to the functioning of the Ac-Ds transposon system in small grain cereals such as barley, wheat, and oat. Methods and compositions for using this system for introducing recombinant expression cassettes and transposon tagging of genes in small grain cereals are provided.
摘要:
The current invention provides the Zea mays GRP (ZMGRP) promoter. Compositions comprising this sequence are described, as are plants transformed with such compositions. Further provided are methods for the expression of transgenes in plants comprising the use of these sequences. The methods of the invention include the direct creation of transgenic plants with the ZMGRP promoter by genetic transformation, as well as by plant breeding methods. The sequences of the invention represent a valuable new tool for the creation of transgenic plants, preferably having one or more added beneficial characteristics.
摘要:
The current invention provides the maize A3 promoter and actin 2 intron. Compositions comprising these sequences are described, as well as transformation constructs derived therefrom. Further provided are methods for the expression of transgenes in plants comprising the use of these sequences. The methods of the invention include the direct creation of transgenic plants with the A3 promoter directly by genetic transformation, as well as by plant breeding methods. The sequences of the invention represent a valuable new tool for the creation of transgenic plants, preferably having one or more added beneficial characteristics.
