US Classification:

4241841, 435239

Abstract:

The present invention relates, at least in part, to novel and improved flow-through purification processes for separating large biomolecules, such as, for example, encapsulated viruses, virus-like particles and conjugate vaccines from one or more contaminants in a sample, where the process employs the use of at least one population of a solid porous particle which comprises a minimized external surface area per unit volume of the particles and an internal surface area per unit volume which is not decreased by more than 25% relative to a population of a similar particle which does not have a minimized external surface area.

Abstract:

An impact mitigation system for an aircraft and method of deploying the impact mitigation system is disclosed. A state parameter of the aircraft is obtained. The state parameter is used with an aircraft performance model to determine an acceleration capability of the aircraft. A trajectory of the aircraft is predicted using the state parameter of the aircraft and the acceleration capability of the aircraft. A location of an object with respect to the aircraft is determined and the impact mitigation system is deployed when the predicted trajectory indicates a contact with the object at a predicted contact velocity higher than a threshold velocity at a future time.
