Abstract: Implicit dependences allow a user to add multiple independent software components to a workspace, which results in the automatic establishment of ad-hoc dependencies. If one project depends on the products of another in the same workspace, a dependency manager detects this, causing a build engine to automatically build the projects in the correct sequence. Each project retains its individual identity, so a project can be included in more than one workspace or removed from a workspace without affecting the project. The workspace module maintains pointers to the projects and other files that the workspace includes. A target and the product it creates can be related to another target. If both targets are in the same workspace, the dependency manager discovers the dependency and the build engine builds the products in the required order. Such a relationship is referred to as an implicit dependency.

Abstract: An additive concentrate for improving the lubricity of low sulfur fuels comprises an additive composition diluted in an aromatic solvent, said composition comprising the reaction product of a first glyceride possessing an unsaturated fatty acid content of at least about 40 mole %, based on the total weight of fatty acid present in the first glyceride, and an iodine number of greater than 35, a second glyceride possessing an unsaturated fatty acid content of less than about 20 mole %, based on the total weight of the fatty acids present in the second glyceride, and an iodine number of less than 35, and, at least one alkanolamine. The concentrate remains fluid and stable at low temperatures and, when added to low sulfur fuels, improves lubricity, enhances fuel economy and minimizes engine deposits.
