Abstract: This document discloses system, method, and computer program product embodiments for dynamically assigning vehicles or other objects to fleets of multiple tenants. Each tenant will be assigned a primary fleet of objects (such as vehicles) and will be associated with a minimum service level requirement and parameters governing operation of each object that is assigned to that primary fleet. The system will maintain a common fleet of vehicles, from which objects may be temporarily assigned to the primary fleets. When one of the tenants submits a service request, the system will select an object from the common fleet, assign the selected object to the primary fleet of that tenant's primary fleet, and cause the object to fulfill the first trip request in accordance with the set of parameters governing operation of each object that is assigned to the primary fleet of that tenant.

Abstract: Reticulated stereo module for the construction of buildings of the type that uses elements of reticulated stereo octahedral type and quadrangular panels for the construction of walls, floors and ceilings, which consists of 4 upper diagonal bars, 4 lower diagonal bars, 4 horizontal bars in the center in a crosswise direction, and 1 strut bar placed between the lower vertex and the central node and/or 1 tension bar placed between the upper vertex and the central node.

Abstract: A FRET based reporter system utilizing the fluorescent semiconductor quantum dots (QDs) and restriction enzymes expressed in cell-free system has the potential to detect multiple analytes in single reaction.

Abstract: Lipase activity can be detected with a biosensor that includes a quantum dot adhered to a construct having a lipase-cleavable ester to attach a fluorophore acceptor configured as a Förster resonance energy transfer (FRET) acceptor to the QD when the construct is bound thereto. Cleavage of the ester by a lipase results in a measurable reduction in FRET. In further embodiments, the cleavable ester can be used to detect esterase activity, or the ester could be replaced with a glycosidic linkage to detect glycoside activity.

Abstract: A nanoparticle (for example, quantum dot) serves as a substrate for immobilizing enzymes involved in consecutive reactions as a cascade. This results in a significant increase in the rate of catalysis as well as final product yield compared to non-immobilized enzymes.

Abstract: The present invention refers to a mechanically activated cementitious composite for stopping the impact of firearms, which involved the designing of mixes of Portland Composite Cement PCC mechanically activated through high energy mechanical milling (HEM) with other ingredients, such as: Ordinary PCC Cement, fine sand, fibers, and polymeric additives, among other compounds, to prepare high-performance composite walls capable of stopping several calibers up to type 50 (typically loaded in Barret rifles). In accordance with Mexican and U.S. Standards for ballistic tests, which entail the approval of the concrete ballistic-resistant wall as long as it resists one impact with a 50 caliber Barret, the present invention allows the construction of composite walls (with dimensions of 40×40×15 cm) with mechanically activated cement and performance complying with the standards.
