Abstract: Methods and apparatus are provided for performing group-based machine-to-machine (M2M) communication. Machine-type communication (MTC) wireless transmit/receive units (WTRUs) may operate in M2M groups. MTC WTRUs belonging to the same M2M group may receive a broadcast message with a time window on a channel dedicated for receiving data directed to an M2M group. The MTC WTRUs may wake up during the time window and may receive data directed to an M2M group on a dedicated channel. The broadcast message may be broadcasted via a broadcast server upon a request from an MTC server. The time window is allocated upon a request from an MTC server on behalf of the M2M group.

Abstract: Gamma-hydroxybutyrate (GHB) can be used as a recreational party drug, aphrodisiac, and attenuator of other drugs and make a person a vulnerable target of robbery or rape. The present invention provides methods and kits for detection of GHB in a sample using an antibody-based assay. Antibodies that specifically bind to GHB or the conjugates of GHB and its derivatives to larger molecules and methods for detecting GHB or its derivatives in bodily fluids and non-alcoholic and alcoholic drinks by employing such antibodies in ELISA or RIA assays are provided by the present invention.

Abstract: A constructional element of constant L-shaped cross-section formed by two metal flanges joined together at right angles has in each flange at least one row of regularly-spaced apertures extending longitudinally thereof. Each row comprises alternate circular apertures and non-circular apertures, the latter being elongated both parallel to and transversely to the length of the element. The rows of apertures in the flanges closest to the junction are offset with respect to each other so that the circular holes in one row register transversely with the non-circular holes in the other row. By the provision of non-circular apertures elongated in two directions, the versatility of the element when used in the fabrication of structural units and frameworks is enhanced.
