A grey water toilet system utilizing a pedal interface to trigger the toilet flush and to resupply the toilet tank with grey water. The grey water is generally collected from a nearby water fixture such as a wash basin and placed in a storage reservoir until the user flushes the toilet. This invention can be used to retrofit most existing toilets without the need for remodeling thus making it possible to expand the use of grey water for toilets, potentially leading the way for significant fresh water savings. It is estimated that the average American residence uses in the range of 100,000 gallons of water annually and that more water is used to flush toilets than any other individual activity.

A method and apparatus are provided for editing video sequences. The method includes the steps of providing a display with a plurality of audio/visual sequences depicted on the display where each audio/visual sequence of the plurality of audio visual sequences is displayed as a timeline parallel to a first axis and where each position along the timeline corresponds to a temporal location of audio/visual information within the audio/visual sequence and where the plurality of audio/visual sequences overlap along the first axis, providing a scrubhead line that extends across the plurality of timelines and that is adapted to be moved relative to the timelines of the plurality of audio/visual sequences and simultaneously displaying audio/visual information from each of the plurality of audio/visual sequences within a respective window of the audio/visual sequences where the displayed information corresponds to a location of the scrubhead line along the respective timeline of the plurality of audio/visual sequences.

A carbon/carbon composite in which a carbon matrix containing a controlled amount of boron or a boron compound is reinforced with carbon fiber exhibits a low coefficient of friction, i.e., on the order of 0.04 to 0.1 at temperatures up to 600&deg; C., which is one of the lowest frictional coefficients for any type of carbonaceous material, including graphite, glassy carbon, diamond, diamond-like carbon and other forms of carbon material. The high degree of slipperiness of the carbon composite renders it particularly adapted for limiting friction and wear at elevated temperatures such as in seals, bearings, shafts, and flexible joints

A UL9 substrate for detecting helicase activity in a UL9 protein is provided. In one embodiment, the substrate includes a first strand including a herpes replication origin sequence and a first single stranded tail; and a second strand including a sequence complementary to the herpes replication origin sequence. In one variation, the first single stranded tail is 3' relative to the herpes replication origin sequence. The second strand may optionally further include a single stranded tail. The single stranded tail on the second strand may be 3' or 5' relative to the sequence complementary to the herpes replication origin sequence. In another variation, the first single stranded tail is 5' relative to the herpes replication origin sequence. The second strand may optionally further include a single stranded tail. The single stranded tail on the second strand may be 3' or 5' relative to the sequence complementary to the herpes replication origin sequence. The UL9 substrate may optionally further include at least one detectable marker attached to at least one of the first and second strands. The UL9 substrate may also optionally be attached to a solid support.
