摘要:
An isolated immunoreactive molecule (IRM) capable of binding to a target molecule from at least one species or sub-species of the insect but not to at least one other species or sub-species of insect and a method of identifying one or more insect species or subspecies and kits therefor. The invention is particularly useful for distinguishing between Lepidopterans such as Helicoverpa armigera and H. punctigera.

The invention provides liquid electrographic toner compositions comprising a liquid carrier having toner particles and at least one soluble polymer dispersed in the liquid carrier. The liquid carrier has a Kauri-Butanol number less than about 30 mL. The toner particles comprise polymeric binder comprising at least one amphipathic copolymer comprising one or more S material portions and one or more D material portions. The soluble polymer is present in an amount of from about 1% to about 10% by weight based on toner particle weight. The absolute difference in Hildebrand solubility parameters between the soluble polymer and the liquid carrier is less than about 3.0 MPa1/2. In one aspect of the invention, the soluble polymer that is incorporated in the toner composition has no more than about 30% weight ratio chemical constitution variance from the chemical constitution of the S material portion of the amphipathic copolymer. In another aspect of the invention, the soluble polymer that is incorporated in the toner composition has no acidic functionality having a pKa greater than 8, and has no basic functionality having a pKa of its conjugate acid that is greater than 8. Methods of making these compositions are also provided.
摘要:
A low temperature fusing dry electrographic toner composition has a plurality of dry toner particles, wherein the toner particles comprise polymeric binder comprising at least one amphipathic copolymer comprising one or more S material portions and one or more D material portions. The dry electrographic toner composition comprises a volatile plasticizer in an amount effective to reduce the First Heat Exposure Tg by at least about 10° C. as compared to a like electrographic toner composition that does not comprise volatile plasticizer. The plasticizer is sufficiently volatile that the Second Heat Exposure Tg will increase by at least about 5° C. above the First Heat Exposure Tg. Methods of making and of using these compositions are also provided.

摘要:
A tampon showing improved leakage protection through improved expansion characteristics is disclosed. The tampons disclosed demonstrate these improved expansion characteristics particularly in the width dimension without introducing new drawbacks. Preferred tampons are described which are compressed to an initial size comparable to current tampons, but which expand to a width exceeding that achieved by current tampons. Such increased expansion is preferably accomplished without an increase in the total absorbency of the tampon. Tampons of various absorbencies are disclosed having increased total expansion in the width direction compared to current tampons. Additionally, tampons of various absorbencies which expand to a greater degree in the width direction under pressure are also disclosed. Tampons of various absorbencies which expand at a rate exceeding that achieved previously are also disclosed. Microwave conditioning of tampon pledgets following compression is disclosed as part of the tampon formation process.

摘要:
A low temperature fusing dry electrographic toner composition has a plurality of dry toner particles, wherein the toner particles comprise polymeric binder comprising at least one amphipathic copolymer comprising one or more S material portions and one or more D material portions. The dry electrographic toner composition comprises a non-volatile plasticizer in an amount effective to reduce the First Heat Exposure Tg by at least about 10° C. as compared to a like electrographic toner composition that does not comprise non-volatile plasticizer. The plasticizer plasticizer is sufficiently non-volatile that the Second Heat Exposure Tg will not increase by an amount greater than about 5° C above the First Heat Exposure Tg. Methods of making and of using these compositions are also provided.
