Abstract: Method and system is described for modeling one or more geophysical properties of a subsurface volume. In one example, a method for predicting strength anisotropy in subsurface formations along a wellpath comprises receiving a stress model of the subsurface formation in the area of the wellpath. Bulk strength properties of target rock are obtained and used to develop anisotropic failure criteria. The stress model may then be combined with the anisotropic failure criteria to develop an anisotropic wellbore stability model which is used to enhance hydrocarbon recovery.

Abstract: A cathode, electrochemical cell and process for making either is disclosed. The cathode includes iron disulfide which exhibits multiple peaks representing distinct maxima of mean diameters for the volume-based particle size distribution. All of the maxima are less than 20 microns. A combination of natural pyrite ore and synthetic iron disulfide may be mixed to achieve the desired distribution, or a combination of natural pyrite ores may be processed in different manners to achieve the desired characteristics.

Abstract: A method for predicting node blockage in a telecommunications network includes determining an aggregated load on a network node and determining a current level of blockage on the node. A demand on the node is projected based on the determined aggregated load. A level of blockage of the node is then projected based on the projected demand and the determined current level of blockage.

Abstract: A cantilevered electrical light fixture (10) has a power supply line (30) running through it from a mounted end (17) to an internal connection zone (36) at a cantilevered end (18). A cover (52) closes the internal connection zone (36) and mounts a plug-half (40) and a switch (42), which are electrically connected to the power supply line (30). A light head (16) mounted to the cantilevered end (18) by a post (76) with a non-circular portion (78) and a threaded shank (80) has lamp wiring (110) connected to a plug-half (120) which releasably mates with the plug-half (40) mounted to the arm (12). A U-shaped bracket (116) mounts a socket (114) to a shell (84) of the light head (16) to bias the lamp bulb (154) against the shell (84).
