Abstract: A lubricant composition comprising a dispersant and a base oil comprising more than about 1.6% by weight of tetracycloparaffins is disclosed. Methods of making and using the lubricant composition are also disclosed.

Abstract: A method of enhancing the operation of diesel fuel combustion systems in a combustion system includes supplying a fuel and additive that includes a manganese compound to a diesel fuel combustion system. The fuel is then combusted in the combustion chamber to produce at least one byproduct including the manganese compound. The manganese compound is supplied in an amount effective to complex with the combustion byproduct. The diesel fuel combustion system operation is enhanced by improving the attributes of lubricating oil loaded with the combustion byproduct soot particles.

Abstract: There is disclosed a lubricating composition comprising a friction modifier and a base oil comprising less than about 3% by weight of tetracycloparaffins. Methods of making and using the composition are also disclosed.

Abstract: A lubricant composition comprising a detergent and a base oil comprising less than about 3% by weight of tetracycloparaffins is disclosed. Methods of making and using the composition are also disclosed.

Abstract: There is disclosed a lubricating composition having a base oil, a friction modifier, and a dispersant, wherein the lubricating composition has less than about 325 ppm of boron. Methods of making and using the disclosed lubricating composition are also disclosed.

Abstract: A lubricant composition comprising a phosphorus-containing compound and a base oil comprising less than about 3% by weight of tetracycloparaffins is disclosed. Methods of making and using the lubricant composition are also disclosed.

Abstract: A lubricant composition comprising a dispersant and a base oil comprising less than about 3% by weight of tetracycloparaffins is disclosed. Methods of making and using the lubricant composition are also disclosed.

Abstract: A method for reducing friction coefficients and wear between lubricated surfaces. The method includes providing an amount of an oil-soluble or oil-dispersible component selected from the group consisting of a photo-crosslinkable poly(2-cinnamoyloxyalkyl acrylate) core and a diblock acrylate copolymer corona in a fully formulated lubricant composition containing a base oil of lubricating viscosity. The lubricant composition containing the component is applied to a surface to be lubricated.

Abstract: The present invention is a thorax phantom that enables simulation of tumor motion within a tissue equivalent material. The system consists of a tissue equivalent epoxy phantom representing a 15 cm axial section of the human thorax that includes simplified spine and lung anatomies. Within the phantom are thru rods of similar tissue density. The rods are attached to a computer-controlled actuator that facilitates both linear and rotational motion of the rods within the phantom. A plurality of tumor targets and radiation detectors can be placed within the rods at various locations thereby enabling the simulation of respiratory and cardiac induced tumor motions within the phantom and assessment of the effects of these motions on image acquisitions, treatment planning and radiation treatment delivery.

Abstract: The boundary friction properties of lubricating oils are improved by including at least one polymeric ethylene-alpha-olefin copolymer derived dispersant and a molybdenum compound into a lubricating oil of a lubricating viscosity. A concentrate for addition into an oil of lubricating viscosity is also disclosed.

Abstract: A self contained set of imaging apparatus which permit an excised tissue to be handled, inked, imaged in radiology and transported to pathology untouched by human hands. Absolute margins of tissue are inked by solution injected into sealed, disposable bag from syringe attached to the bag. Inked tissue is removed from bag and placed upon fluid-absorbent blotter inscribed with radiographically opaque grid, inside of transparent container. Hinged top and bottom panels of liquid-tight container secure tissue in place. Tissue is visible from outside of container during transport, x-ray imaging, and subsequent pathologic evaluation. Further, the image presented to the pathologist with the inked tissue permits extremely accurate identification of locations of suspect element. The pathologist can easily view the enclosed, undisturbed sample and associated radiograph prior to dissection which can be done within said apparatus if so desired.
