Abstract: Techniques for an ontology-based approach for modeling service dependencies in a provider network. The approach is flexible and extensible to different provider network SOA systems and not limited to a particular provider network or a particular SOA system. The approach can be used to model an entire SOA system or selected portion thereof and from different perspectives. In some examples, the approach uses an ontology represented using a Web Ontology Language (OWL). In some examples, the ontology is used to identify service dependencies and relationships in a knowledge base that is populated based on operational data collected in the provider network environment.

Abstract: A composition that has insect repellent properties is made from essential volatile oils. The inventive composition includes a combination of menthol, eucalyptus oil, citronella oil and/or tea tree oil, alcohol, water and skin moisturizing components. Menthol in crystal or liquid form. Essential oil of eucalyptus. Essential oil of citronella and/or tea tree oil. Isopropyl alcohol, grain alcohol or any other type of distilled alcohol. Deionized, distilled or any other type of sterile water. Skin conditioning oils including but not limited to mineral oil, jojoba oil, glycerin, Vitamin E. The topical composition can be formulated as a solution, suspension, cream, ointment, gel, film or spray.

Abstract: A basic airfoil has its operating performance improved by incorporating one or more apertures in the airfoil adjacent its trailing edge. These apertures extend from the upper surface of the airfoil down through to the lower surface of the airfoil. The entry port and the exit port of these apertures has a greater circumference than that of the throat circumference which is intermediate thereto. This structure forms a venturi having a vertical axis. Spaced below the throat of the aperture are a plurality of air nozzles that communicate with an air plenum chamber within the airfoil. A source of pressurized air is connected to the plenum chamber. The leading edge of the airfoil causes air to flow across both the upper surface and lower surface of the airfoil. The venturi creates a strong suction on the upper surface of the airfoil to enhance the airfoil's pressure differential.
