Abstract: An intraurethral device for use in a female urinary tract is provided. The intraurethral device comprises a urethral element that contains a chemical compound capable of treating or detecting the presence or absence of a disorder or disease. In one embodiment, the intraurethral device also contains outer and inner insertion elements that are in operative communication with the urethral element to facilitate the insertion of the urethral element into the urethra without substantially contaminating the chemical compound prior to insertion.
Abstract: High performance electromechanical devices suitable for a wide range of applications are described. The electroactive devices are capable of operating in a manner that offers enhanced mechanical displacement responses and increased load-bearing capabilities. In one embodiment, the device is capable of providing a significantly increased level of free displacement. The electroactive devices include an electroactive composite which includes at least one electroactive material that may comprise an electrostrictive or a piezoelectric material and a tensioning device which is adapted for inducing a mechanical pre-load to the electroactive composite structure. The tensioning device exerts a mechanical pre-load upon the electroactive material which alters stress profile, increases mechanical energy and increases stored elastic energy of the electroactive devices.
Abstract: The ability to transport body liquids in consumer products such as diapers, incontinents and feminine napkins is a key factor in their performance. This invention is designed to provide specific high fluxes (volume of liquid/(time*mass of polymer) of aqueous liquids in designated directions using bundles of new specially designed fibers. The key factors for the bundles are a high specific adhesion for the liquid of interest, a high specific volume of the bundle itself, and alignment of the fibers within the bundle. The invention includes novel liquid acquisition/distribution systems and absorbent products that include a liquid acquisition/distribution system which may incorporate the novel bundles of fibers.

Abstract: The present invention generally relates to various methods for promoting ovulation, parturition and lactation in female mammals. These benefits are obtained by administering to the mammals a composition containing a D2 receptor antagonist that does not substantially cross the blood brain barrier. In one embodiment, the D2 receptor antagonist is domperidone. The domperidone can be administered to the mammal either orally or subcutaneously and can be used to treat, for instance, anestrous mammals, mammals that have problems bearing offspring and mammals suffering from agalactia. Unexpectedly, it has also been discovered that the D2 receptor antagonist may also stimulate feed intake, causing the mammal to eat more and gain weight faster.
Abstract: An intraurethral device that can be used to inhibit leakage of urine due to incontinence is provided. The intraurethral device can include a urethral plug made from a biocompatible, flexible material. The intraurethral device can also include a first insertion element in operative communication with a second insertion element to facilitate self-insertion of the urethral plug into the urethra. Furthermore, in some instances, various mechanisms can be provided to keep the intraurethral device substantially sterile and/or clean prior to and/or during the insertion process.
Abstract: A plant propagation apparatus is disclosed which comprises a flexible transparent enclosure. The enclosure is disposable, and could be formed of a polymer such as polyethylene. The enclosure would have at least two walls, formed of flexible material that facilitates transmission of light through the walls. Plant material is sealed within the enclosure, and nutrient solution is made available within the sealed enclosure for the plant. The enclosure is a low cost and effective method for propagating young plants and transporting them between the laboratory environment and a greenhouse or field. The enclosure may be configured to receive gas or carbon dioxide on its inner surface to a predetermined level of pressure, thereby affording the enclosure a flexible but stiff mechanical resistance that protects the young plant while it is growing.

Abstract: Crystalline colloidal arrays (CCA) which have been encapsulated in a polymer matrix to produce more robust polymerized crystalline colloidal arrays (PCCA) are provided. The PCCA's of the present invention can be in the form of a hydrogel which can be compatible for use with a biological system. The polymer matrix of the PCCA is formed of polymerized poly(ethylene glycol) based monomer units which can provide a desired functionality to the PCCA. The PCCA can be formed to exhibit a photonic bandgap at a certain wavelength. The photonic bandgap can be capable of shifting upon some form of environmental stimulation rendering the PCCA suitable for many optical applications, including active photonic switching and sensory applications.

Abstract: An intra-urethral device that can be used to inhibit leakage of urine due to incontinence is provided. The intra-urethral device can include a urethral plug made from a biocompatible, flexible material, and can be formed into an oblong shape so as to better correspond to the contours of the female urinary tract. In some instances, the intra-urethral device can also include an insertion element that can facilitate self-insertion and the ability of a fluid seal to form between the urethral plug and the walls of the urethra. Furthermore, in some instances, various mechanisms can be provided to keep the intra-urethral device substantially sterile throughout the insertion process.

Abstract: A system and apparatus for growing plants is disclosed. The system includes a first thermal panel with multiple flow channels, the thermal panel being located between a growing space and a light source. A cooling fluid is circulated in a countercurrent flow pattern (i.e. in at least two different directions). The channels may be connected to one or more headers, which serve as a fluid manifold to deliver fluid and collect fluid from the flow channels. Growing closely spaced plants from seed or cuttings to transplants for the field or a greenhouse is one application of this system.

Abstract: The invention provides synthetic polymeric fibers which have utility as temporary acquisition/distribution absorbent structures and permanent storage/distribution absorbent structures in a wide range of absorbent products such as diapers, feminine napkins, and adult incontinent pads. These fibers are short, highly distorted, and bulky characterized by lengths between 2 and 37 mm, short-range distortion factors between 5 and 70, long-range distortion factors between 0.05 and 0.9, and single fiber bulk factors between 0.5 and 10.0. They may or may not have capillary channels on the surface. The advantages of these materials are their increased absorbency, reduced wet collapse at low densities, reduced rewet, reduced loss of liquid under pressure, and their ability to be desorbed by distribution materials such as capillary channeled fibers or by conventional storage materials such as fluff pulp or superabsorbent polymer fiber or powder.
