Abstract: Techniques for selecting a digital image are disclosed. The techniques may include receiving a first set of digital images, analyzing the first set of digital images to extract first image features from each of the first set of digital images, accessing a user profile, comparing the extracted first image features to a preset list of image features, ranking each digital image of the first set, selecting each digital image having a ranking that exceeds a threshold, assigning a category to each selected digital image based on a comparison of each selected digital image to a category database of digital image categories, displaying each selected digital image with the assigned category, receiving an input from the user in response to the displaying, updating the user profile and the category database based on the input, and selecting at least one subsequent digital image based on the updated user profile and category database.

Abstract: Compositions and methods are described for transparent glass composite having nanoparticles therein that scintillate in the presence of nuclear radiation, particularly gamma rays, but also x-rays, alpha particles, beta particles, and neutrons. The transparent glass composites can be prepared by a melt/cool process to produce the transparent glass composite. The wavelength of light emitted by the transparent glass composite can be tailored based on the materials used to make the glass composite. A detector that utilizes the transparent glass composite can measure nuclear radiation from numerous sources.

Abstract: A closure mechanism for use with bag- or sachet-like packaging which is substantially formed by opposing sheets of polymeric material; wherein said closure mechanism includes first and second sets of opposing substantially parallel ridges, said ridges defining complementary grooves therebetween that are adapted to receive said opposing ridges in a form-locking engagement; wherein the surface of said ridges and grooves feature a plurality of ribs extending traverse and from said surfaces such that, when said first form-locking engagement is made, the ribs extending from said ridges tend to interfere with the ribs extending from said grooves thereby to impede unintentional opening of said closure.

Abstract: A device for use in culturing a cell is provided. The device comprises at least one cell culture chamber and a fluid reservoir. The cell culture chamber has a tapered side wall and is in fluid connection with the fluid reservoir via a fluid path which is connected to the culture chamber via an aperture in the culture chamber. The aperture is smaller than the diameter of the cell to be cultured such that the cell is maintained within the cell culture chamber.

Abstract: A system for measuring ground reaction force and analyzing the performance of an athlete in which force sensors are located in the athletes shoe and a three dimensional accelerometer is located adjacent the athletes centre of gravity and the signals from the accelerometer and the force sensors are recorded and used to derive the three orthogonal components of the ground reaction force (GRF).
