Abstract: This disclosure is directed to a cap for obtaining a target analyte from a suspension. The cap introduces a magnetic field or a magnetic gradient to the tube to draw the target analyte bound to a particle to the cap. In one aspect, a cap includes a magnetic insert and a receiving piece. The magnetic insert includes a stopper and a magnet extending from the stopper; and, the receiving piece, which is configured to hold the magnetic insert, includes a receiving stopper and a sheath. The sheath may include imaging slides on opposite sides of the sheath. In another aspect, the cap may include a stopper and an embedded magnet. The cap may include an analysis piece on a bottom end of the stopper. In yet another aspect, the cap may include a fluid compartment and a filter at a bottom end of the stopper.

Abstract: Methods of growing and harvesting multiple species of phytoplankton are disclosed herein. The method generally includes four steps, namely: (1) collecting phytoplankton seawater containing multiple species of naturally-occurring phytoplankton directly from a source of seawater; (2) adding nutrients to the phytoplankton seawater to proliferate the multiple species of naturally-occurring phytoplankton to a predetermined density; (3) separating the multiple species of naturally-occurring phytoplankton from the phytoplankton seawater to form a phytoplankton concentrate; and (4) collecting the phytoplankton concentrate such that the collected phytoplankton of the phytoplankton concentrate remain in a substantially intact cellular state.

Abstract: Rock physics guided migration is disclosed to enhance subsurface three-dimensional geologic formation evaluation. In one embodiment, a geologic interpretation is generated based on a seismic data volume. Sets of compaction and acoustic formation factor curves are generated, and these are combined into a set of velocity-relationship curves. A pore pressure is derived and used to establish a pore pressure state. A rock physics template is then generated utilizing the derived information. This rock physics template can be used to refine geologic formation evaluation with any suitable form of migration technique.

Abstract: This disclosure is directed to systems for separating a target analyte from a suspension. A suspension is added to a tube. A float is also added to the tube, and the tube, float, and suspension are centrifuged together, causing the constituent components of the suspension to separate into different layers along the axial length of the tube according to their specific gravities. The float has a specific gravity that positions the float at approximately the same level as a layer containing the target analyte, when the tube, float and sample are centrifuged. Prior to isolation, the material may be located between an outer surface of the float and an inner surface of the tube, or within a central bore that extends longitudinally through the float. The target analyte may then be drawn into a compartment within the float, thereby isolating the target analyte from the other suspension constituents.
