Abstract: Example methods and apparatus to present recipe progress status information are disclosed. A disclosed example method involves displaying a user interface screen associated with a recipe being executed in a process control system. The recipe includes a plurality of process phases. A plurality of process stage progress indicator are displayed in the user interface screen in an arrangement representative of the process flow of the recipe. Each of the process stage progress indicators is representative of at least one of the process phases of the recipe. A first one of the process stage progress indicators is indicative of a progress of at least one of the process phases. The first process stage progress indicator is updated in substantially real-time based on information received from the process control system.

Abstract: An exemplary system for managing the deployment of a seismic data acquisition system uses a module configured to execute a plurality of task in the field by receiving one or more seismic devices. The module may include a power source that provides electrical power to the seismic devices. The module may also include a processor programmed to retrieve data stored in the seismic devices, perform diagnostics, facilitate inventory and logistics control, configure seismic devices and update data or pre-programmed instructions in the seismic device.

Abstract: Chelating ligand precursors for the preparation of olefin metathesis catalysts are disclosed. The resulting catalysts are air stable monomeric species capable of promoting various metathesis reactions efficiently, which can be recovered from the reaction mixture and reused. Internal olefin compounds, specifically beta-substituted styrenes, are used as ligand precursors. Compared to terminal olefin compounds such as unsubstituted styrenes, the beta-substituted styrenes are easier and less costly to prepare, and more stable since they are less prone to spontaneous polymerization. Methods of preparing chelating-carbene metathesis catalysts without the use of CuCl are disclosed. This eliminates the need for CuCl by replacing it with organic acids, mineral acids, mild oxidants or even water, resulting in high yields of Hoveyda-type metathesis catalysts.

Abstract: The invention provides surface coating compositions comprising a preservative comprising 9-decenoic acid, salts of 9-decenoic acid, esters of 9-decenoic acid, or combinations thereof. The surface coating compositions may be water-based coatings (e.g., a latex paint) or solvent-based coatings (e.g., a solvent-based paint). The surface coating compositions may be paints, stains, varnishes, concrete coatings, anti-graffiti coatings, and the like. Methods for protecting a surface coating composition from in-can spoilage and protecting a coating of the surface coating composition from deterioration by the action of microorganisms are also described.

Abstract: This invention herein describes a method of facilitating the entry of drugs into cells and tissues at physiologically protected sites at pharmacokinetically useful levels and also a method of targeting drugs to physiologically protected sites in vivo. Also provided are drug conjugates with an amino acid or derivative thereof for facilitating such targeted drug delivery. The conjugates and methods of this invention provide an advance over other drug targeting methods known in the prior art, because the invention provides drug concentrations in such physiologically protected sites that can reach therapeutically-effective levels after administration of systemic levels much lower than are currently administered to achieve a therapeutic dose. This technology is appropriate for use with psychotropic, neurotropic, neurological, antibiotic, antibacterial, antimycotic, antiviral, antiproliferative or antineoplastic drugs, agents and conjugates, for rapid and efficient introduction of such agents across, e.g.

Abstract: A disk drive provides temperature compensation for write current. The write current not only provides an acceptable bit error rate for data written to and read from the disk, but also prevents write induced instability in the head. Furthermore, the write current prevents excessive pole tip protrusion. As a result, the write current ensures that data is reliably stored and retrieved at a given temperature.
