Abstract: An antibacterial peptide obtainable from a S. mitis and S. oralis; or a variant thereof, or a fragment of any of these, for use as an antibacterial agent. Specific peptides have been identified. These peptides are secreted by strains of S. mitis or S. oralis. They are active against inter alia gram negative bacteria and Staphylococcal spp. The peptides may be isolated for use or the S. mitis or S. oralis may be used in a probiotic therapy.

Abstract: A removable fletch, system utilizing the fletch, method of installing the fletch, and kit comprising the fletch and an installation jig. The fletch comprises a feather member extending from a mounting body in a first direction, and one or more locating pins and a locking pin extend from the mounting body in a second direction. The locating pins are insertable within holes disposed in the wall of a hollow-shafted archery arrow. The locating pins define angled engagement notches that contact the inner surface of the arrow body such that translation of the fletch with respect to the arrow body causes the fletch to be pulled tightly against the arrow body. The locking pin may be snapped into a corresponding hole within the arrow wall, thereby fixing the fletch to the arrow body. An installation drill jig may be used to drill holes within the arrow wall corresponding to the locating and locking pins of the fletch.

Abstract: The run-time available from an uninterruptible power system is accurately determined both during supply of power from the battery to the load and during the time where power is supplied directly from an AC power system to the load. During power outages, where power is supplied from the battery through the inverter to the load, the remaining run-time is first estimated by calculation and then corrected by modification of the calculated value according to the reciprocal of the run-time slope. Alternatively, a scaling factor is used as part of the first run-time calculations and a correction factor which applies more corrective weight as the time on inverter progresses may be used. During power outages and when power is supplied from the AC power system to the load the maximum available run-time is extrapolated from a table of values representing maximum available run-times at various levels of power being supplied to the load from a fully charged battery.
