摘要:
Disclosed are multilevel interconnects for integrated circuit devices, especially copper/dual damascene devices, and methods of fabrication. Methylated-oxide type hardmasks are formed over polymeric interlayer dielectric materials. Preferably the hardmasks are materials having a dielectric constant of less than 3 and more preferably 2.7 or less. Advantageously, both the hardmask and the interlayer dielectric can be spincoated.

A control system for managing the operation of a tractor PTO using input conditions occurring in a connected baler. Baler conditions such as tailgate position, crop pickup position, bale wrapper status, and driveline torque are sensed in the baler, and communicated to an implement-mounted controller whereupon control signals are initiated and communicated to a tractor-mounted controller to manage operation of the tractor's PTO. Safety may be maintained through the use of operator acknowledgements in order to prevent unexpected engagement of the PTO and a manual override capability allows an operator to suspend automated operation at any time.

An in vitro method for testing the effectiveness of antiviral agents is provided. The method allows for screening anti-papillomavirus drugs which can interfere with the early and maintenance stages of papillomavirus infection. The method comprises growing epithelial cells susceptible to infection with papillomavirus in a monolayer system and measuring the effectiveness of various agents present in the growing media to interfere with the growth of the virus. The method is free from interferences caused by the regional variability, since the cell cultures are evenly dispersed monolayers.

Band members use their own performance during a song to reinstate a band member who has failed during the course of the song. Once a band member has failed, options are given to other members of the band who have achieved a predetermined bonus or performance level to save the fallen band member. Once saved, the failed member returns to normal play of the song. In this manner, failure still has the consequence of removing a player from a song at least temporarily, and perhaps permanently if bandmates are unable or unwilling to save the fallen member. However, by providing the option of reinstatement, band members can prevent their friends from long stretches of inactivity following a failure. This may have the added benefit of encouraging band members to perform strongly in order to be able to save their friends.

The invention is an improved multiplex capillary electrophoresis instrument or module with at least four and preferably six user-accessible vertically stacked drawers. An x-z stage moves samples from the user accessible drawers to the capillary array for analysis. A computer program allows users to add capillary electrophoresis jobs to a queue corresponding to the analysis of rows or plates of samples without stopping or interrupting runs in progress.

A draft load control system for an agricultural tractor coupled to a semi-trailed, ground-engaging implement that monitors implement height using sensors located on the tractor or sensors coupled to an on-board control communications system and adjusts the implement position in relation to the ground through coordinated action of the three-point hitch and the on-implement position actuator based on draft load, implement height, and tractor wheel-slip to maintain a more accurate, consistent draft load on the tractor while maintaining the implement engaged with the ground and preventing the tractor-implement ground speed from being reduced to zero.
摘要:
An engine debris guard for preventing tyre propelled debris striking an aircraft engine, the debris guard comprising a guard bar pivotably connected to an aircraft main landing gear having at least one wheel and tyre assembly, the guard bar being arranged to be movable between a first position and a second position wherein in the first position the guard bar extends laterally across the wheel and tyre assembly to intersect the possible trajectories between the wheel and tyre assembly and an engine of the aircraft of any tyre propelled debris.
