Abstract: This is an early warning method for a shallow soil landslide based on a digital topographic map, belonging to the field of landslide prevention and control engineering. It has following steps: a. connecting a straight line along an upward bulged intermediate point of a contour line of the topographic map as an intermediate line; b. determining an intermediate point; c. constituting a three-point group of a plane curvature; d. taking an arithmetic average of slopes as a slope ? of a landslide mass. The shallow soil landslide can be early warned without a lot of historical observation data of landslide occurrence, and the dangerous landslide mass can be determined in advance, which greatly improves the applicability of disaster prevention and the early warning efficiency.

Abstract: An integrated method for clearance, collection and capture of internal pollutants and algae at the bottom of a lake include the following steps: selecting areas where the pollution level is high, and organic or inorganic particulate matter is prone to accumulation and carrying out trenching operations at the bottom of the lake to form a plurality of traps; and removing the sludge and algae inside the traps and clearing the sediment inside the traps, for subsequent internal pollution control when the surface-layer sludge on both sides of the traps almost fills up the traps. This method makes use of the hydrodynamic disturbances of waves formed by natural wind energy and lake currents to continuously transport sludge with a high pollution level and a small specific gravity and algae in the surface layer of the lake bottom, which are rich in organic debris, to artificially built traps.

Abstract: The present invention is directed to a multiplexed system for electrospraying cooling fluid to produce electrically charged droplets essentially uniform in size for cooling applications. The system comprise a preferably microfabricated fluid distributor consisting of multiple nozzles/atomizers from which the droplets are dispersed, an extractor electrode consisting in an electrically conductive plate with multiple holes coaxial with the nozzles and a third electrode consisting of either the surface to be cooled or another conductive material in contact with said surface. The system provides highly efficient cooling by avoiding the droplet rebound, when the charged droplets are pinned on the surface to be cooled by the electric image force. Testing of a prototype system demonstrated a heat flux removal of 96 W/cm2 with a remarkable cooling efficiency reaching 97%.

Abstract: A particle generation apparatus and a particle generation method each employ: (1) a nozzle from which exits a liquid micro-jet stream; and (2) a ground electrode separated from the nozzle, where both the nozzle and the ground plane are DC voltage biased when operating the nozzle. Each of the particle generating apparatus and the particle generating method also employ a pair of AC electrodes interposed between the nozzle and the ground electrode and perpendicular to the liquid micro-jet stream. When a liquid supply is supplied to the nozzle, a DC voltage bias is supplied to the nozzle and the ground electrode, and an AC voltage bias and AC frequency bias is applied to the pair of AC electrodes a liquid particle spray is generated by the apparatus and the method. With additional parametric adjustment, the liquid particle spray may be monodisperse and bifurcated.

The distributor electrode comprises other than a silicon material (i.e., a metal, metal alloy, ceramic or polymer material). The distributor electrode may be fabricated using a computerized numerical control method that provides the coating method with enhanced uniformity. The nozzle and the apparatus may also use a stepped slotted extractor electrode.
