Abstract: The present disclosure is directed to a multi-functional composition including activated carbon that is useful for injection into aqueous mediums such as soil or groundwater for sequestration of contaminants in a contaminated plume. The composition of activated carbon may include physical and chemical properties to enhance mechanism of contaminant physisorption and chemisorption including enhanced adsorption kinetics through manipulation of particle surface area, enhanced capacity and selectivity through controlled pore size distribution and enhanced electrostatic and hydrophobic interactions with contaminants. The multi-functional composition may further include a positively-charged nitrogen-functionalized organic compound and/or moieties that improve the activated carbon's ability to sequester contaminants in a subsurface environment.

Abstract: A means for collecting distilled water is disclosed which comprises a distillation cell or an array of such cells each cell comprising taut transparent sheets arranged around a collection point for such distilled water and means for collecting such distilled water.

Abstract: A method of monitoring machine operation includes sensing an operating characteristic of a plurality of machines and calculating a performance metric. The performance metric is indicative of the operating characteristic of at least a portion of the plurality of machines. The method also includes storing the performance metric and comparing the performance metric to at least one other stored performance metric.

Abstract: An art surface and a method for preparing the same are disclosed. In one embodiment, a coating is disposed on a thermoplastic compatible surface of a substrate. The coating includes a reaction product of a thermoplastic, at least one cellulose fiber, and acetone. Further, the coating is able to accept one or more artistic media such as acrylic, chalk, charcoal, colored pencil, conte, dyes, egg tempera, oil, pastel, or water color, for example.

Abstract: An interposer with a contact well, a layer that isolates one side of the interposer from the other side, for isolations of off gasses, and an optional elastomeric pad and a hard stop layer. Included is a method of making the interposer.

Abstract: Analog signals corresponding to color images or pixels of a thin section of a rock reservoir are digitized and then filtered to isolate the pixels representative of pores in the thin section. The pores so isolated are then counted, measured for their total pore perimeter and labelled.Each area of pixels representative of pores of value one is progressively eroded and dilated, pursuant to which one layer of pixels of ones on the perimeter of the area is converted to zeros and, if a seed pixel remains, one layer of pixels of ones is added to the perimeter of the area. Thereafter, the original object undergoes two successive erosions followed by two dilations if a seed pixel remains. Successive iterations of the erosion and dilation cycle continue until the last erosion eliminates the seed pixel of the area.

Abstract: A method and apparatus for eliminating the necessity of providing hold-down devices, such as spuds and anchors, for opposing buoyancy in tunnel forms. The method comprises providing a movable counterweight car which preceeds the flow of fluid concretes, as it slopes from the crown of the tunnel forms downward and thus provides negative buoyancy at that area where there is the most fluid concrete and in that area where the most uplift occurs as well as the natural area where there are no forces of the crown helping to prevent flotation. The movable counterweight car is a hollow container curved to match the curvature of the excavated tunnel and clearing the movement of the forms. It has wheels that run on single track rails carried on the inside of the tunnel forms, the container being wholly or partly filled with steel scrap or punchings.
