Abstract: A multi-variable work assignment process is used to assign work items, such as voice calls, e-mails and other communications or tasks, to agents in a call venter. The multi-variable work assignment process determines whether values of a particular variable characterizing the work items fall within a designated range, and if so utilizes at least one additional variable for making the work assignment decision. The work assignment process may also or alternatively consider a weighted combination of multiple variables in making the work assignment decision. Examples of variables which may be used in the multi-variable assignment process include current wait time, service objectives skill preference, skill level, anticipated wait time, predicted wait time, etc. The invention may be implemented in a one-to-many work assignment process which selects one of a set of agents available for handling a particular work item, in a many-to-one work assignment process which selects one of a set of work items for handling by a particular available agent, or in a many-to-many work assignment process in which multiple agents are each considered simultaneously for handling multiple work items.

Abstract: A pail and lid with an integral handle molded with the lid includes a pail side wall extending upwardly from the pail bottom to an upper peripheral edge.  The lid includes a cover portion shaped to cover the open top and a peripheral skirt depending from said cover portion, said skirt having an upper annular portion and a lower annular portion and both shaped to surround an outer surface of the pail side wall at or adjacent the upper edge and separated by a peripheral tear strip.  The handle is integrally formed with said lower portion for carrying the pail. The skirt and pail have co-operating upper and lower pairs of retaining lips shaped to snap over each other by downward movement of the cover portion onto the pail to hold the cover portion on the pail. The skirt is sufficiently stiff to allow both snap actions to be effected simultaneously be pressure downwardly from the cover. The lower pair provide greater retaining force such that, prior to pulling the tear strip, co-operation of said lower retaining lip of the peripheral skirt and said lower retaining lip of the pail provides a strong force in maintaining the cover portion on the pail and such that, upon tearing, co-operation of said lower retaining lip of the peripheral skirt and said lower retaining lip of the pail substantially prevents upward vertical displacement of said lower portion and the handle thereon relative to said pail so that the handle can accept high loads.

Title: X-ray compton scatter density measurement at a point within an object
Inventor: ACHMAD BALZA
IPC: G01B15/02
Filed: 2001-08-22
Granted: 2003-11-18
Abstract: The present invention pertains to a non-rotating method for non-intrusively determining the density of a point embedded within an object, without necessarily obtaining a full image for the entire object. The method consists of passing a X-ray beam through a point within an object and measuring Compton scatterings from the point from a first and second energy bands within the energy spectrum of the X-ray beam, along a first and second angles from the X-ray beam. Using the kinetics of Compton scattering at a specific angle, four equations are formulated with four measurements and four unknowns; the radiation attenuation factor along the object between the X-ray source and the point, the radiation attenuation factor between the point and each of the detectors and the density of the object at the point. The four equations are solved simultaneously to determined the four unknowns. There is also provided a matrix inversion process to facilitate the solution of the equations.

Title: The use of 4-h-1-benzopyran-4-one derivatives as inhibitors of smooth muscle cell proliferation
Inventor: DUMONT JENNIFER A
IPC: A61K31/00
Filed: 2000-01-18
Granted: 2009-03-17
Abstract: Smooth muscle cell (SMC) proliferation is a critical component of neointima l formation in many animal models of vascular injury, and in many human lesions as well. Cell cycle inhibition by gene transfer techniques can block SMC proliferation and lesion formation in many animal models, although these methods are not yet applicable to the treatment of human disease. Flavopiridol is a recently identified, potent, orally available cyclin- dependent kinase inhibitor. Given the role of smooth muscle cell (SMC) proliferation i n vascular disease, we tested the effects of flavopiridol, a recently identifi ed cylin-dependent kinase inhibitor, on SMC growth in vitro and in vivo. Flavopiridol (75 nmol/L) potently blocked SMC proliferation, an effect that was associated with downregulation of cyclin-dependent kinase activity and cell cycle-related gene expression. We examined the effects of flavopiridol on SMC proliferation in vivo in the rat carotid injury model. Flavopiridol (5 mg/kg) decreased neointimal size by 35% and 39% at 7 and 14 days, respectively, after balloon injury. Flavopiridol may be a potential therapeutic tool in th e treatment of SMC-rich vascular lesions. 4-H-1-benzopyran-4-one derivatives inhibit smooth muscle cell proliferation at low dosage levels.
