Abstract: This disclosure relates to a combination of a pallet truck and a sled for delivering goods from a truck into a building, a method for making an in-building delivery of palletized loads from a truck, and a dual-use, half-size pallet that can be carried by either the pallet truck or the sled. The pallet truck is shaped and sized to nest with the sled by comprising an alignment feature configured to mate the sled with the pallet truck. The pallet truck is shaped, sized, and constructed to lift the sled along with at least two palletized loads of goods. The pallet truck is also shaped and sized to fit within a bed of a truck. The sled comprises an alignment feature compatible with the alignment feature of the pallet truck, and a lifting mechanism shaped, sized, and constructed to lift at least one of the palletized loads of goods.

Abstract: A plant and a related method for the regeneration of fluorinated compounds, particularly sulfur hexafluoride, includes an inlet section designed to receive a gas mixture with the fluorinated compound to be regenerated, an outlet section designed to convey out the regenerated gas, and a fluid dynamic circuit that connects the inlet section to the outlet section and includes filtering elements. The filtering elements have a separation unit where the gas mixture is brought to a temperature and pressure that cause the fluorinated compound to condense while keeping the other components of the mixture in the gaseous state. The condensed fluorinated compound represents the regenerated compound to be conveyed toward the outlet section.

Abstract: A device for treating fluorinated gases includes an inlet section for receiving a gas to be treated; an outlet section for conveying the treated gas to an outlet; a fluid-dynamic circuit between the inlet and the outlet sections that includes a plurality of branches in parallel; flow cut-off elements that can be controlled via an actuation signal for the closing/opening of the branches of the fluid-dynamic circuit to provide the gas with access to different paths so as to vary the volume available to the gas inside the circuit; a plurality of filtering units arranged at least partly in the branches of the fluid-dynamic circuit to filter the gas; an input for receiving information on gas volume to be treated; and a control unit programmed to read the input and send actuation commands to the cut-off elements to open/close the branches of the circuit according to gas volume.

Abstract: Methods and compositions for detecting molecular interactions, particularly protein-protein interactions, are provided. The invention allows detection of such interactions in living cells or in vitro. Detection of molecular interactions in living cells is not limited to the nuclear compartment, but can be accomplished in the cytoplasm, cell surface, organelles, or between these entities. In one embodiment, the method utilizes novel compositions comprising fusion proteins between the molecules of interest and two or more inactive, weakly-complementing ?-galactosidase mutants. Association between the molecules of interest brings the complementing ?-galactosidase mutants into proximity so that complementation occurs and active ?-galactosidase is produced. The active ?-galactosidase may be detected by methods well-known in the art. Among the uses of the invention are the study of protein-protein interactions, functional genomics, agonist and antagonist screening and drug discovery.
