Abstract: The present invention includes methods for investigating a site for possible selective removal of sediment containing a contaminant. The methods include calculating an adjusted contaminant concentration for sediment zones on the site. The site preferably contains a water course. The methods may also include determining whether sediment zone need remediation by comparing the adjusted contaminant concentration to a standard. The invention also includes a system for carrying out the described methods, at least partially implemented in a computer.

Abstract: A water-based metalworking fluid is comprised of a polymeric boron species which includes at least B, N and H, together with a surfactant operable to provide an emulsion of the boron species with water. The polymeric boron species may be a polyborane or a borazine polymer and may be configured as a polyborane or borazine polymer backbone having side chains pendent thereupon. The side chains may include silicon and/or phosphorous. The silicon may be in the form of a silane or a siloxane species, including polymeric species. Disclosed are specific compositions as well as methods for using the compositions and methods for making the compositions.

Abstract: According to the methods, a site is investigated for possible selective removal of sediment containing a contaminant. An adjusted contaminant concentration is calculated for sediment zones on the site. The site preferably contains a water course. A determination may be made as to whether the sediment zone needs remediation by comparing the adjusted contaminant concentration to a standard. The method may be at least partially implemented in a computer.

Abstract: An industrial or laboratory system that provides sufficient backup of all utilities for sufficient time to allow for orderly shut down of the industrial or laboratory supplied system or the re-establishment of normal utilities. The new backup system stores and uses the facility utilities and supplies the utilities as required to avoid abrupt and potentially damaging shutdown. The new backup system also monitors and regulates the supplied system as necessary and provides communication of backup events through automated telecommunication equipment. Changes in supplied system utilities are automatically logged into an event log to allow an operator to determine which utility has experienced a detectable service interruption, what type of interruption the utility has experienced and the action taken by the computer logic control.

Abstract: A lead frame that does not tie straps and a die bond pad is rectangular in shape, with the same number of lead frame leads (11) on opposite sides and a different number of lead frame lead frame leads (11) on adjacent sides. Lead frame leads (11) extend into the area in which the tie strap would normally be placed. A heat slug is (30) taped into the lead frame to provide a semiconductor die mount area. At least one lead (11) from one side of the lead frame, located where the tie strap is normally located, is connected via a bond wire (17a, 17b) to a bond pad (19) on the semiconductor die (18) on a side adjacent to the side where the lead frame lead is located.

Abstract: A heat spreader (10) is provided for dissipating heat from a semiconductor die (32). The heat spreader (10) comprises a thermally conductive sheet (12) having an aperture (14) formed therein. At least one set of opposing members (20) extends inwardly, but do not contact, within the aperture (14). The opposing members (20) can receive adhesive material for securing the semiconductor die (32) to the heat spreader (10) such that the semiconductor die (32) is disposed over the aperture (14).

Abstract: A soil remediation system (10) for removing contaminants (11) from a contaminated area (12) located in the vadose zone (13) of the earth and comprising multiplicity of stratigraphic zones, contaminants and compositions (26, 28), is disclosed. The system (10) comprises a first circulator (32) for circulating gas through the first zone (26) at a first volumetric rate and a second circulator (38) for circulating gas through the second zone (28) at a second volumetric rate to carry the contaminants in each respective zone (26, 28) to the surface of the earth (15). The system (10) includes a zero or low permeability membrane or layer (34) positioned between the first and second zone (26, 28) to control the commingling of the first and second volumetric flow rates so as to allow removal of contaminates in the first zone (26) independent of the removal of contaminates in the second zone (28).
