A computer implemented system and method for encouraging frequent and purposeful electronic communications from caregivers to individuals with impaired memory to, inter alia, alleviate feelings of isolation and improve memory. The system includes a Web-based application through which caregivers send text, image, voice and other forms of data for receipt by the sufferer on a PDA having a simple user interface. The Web application records the dates and nature (i.e., text, audio, photograph, video) of communications sent by each caregiver, processes the data in order to display it in a variety of meaningful ways to all caregivers, thus creating a peer-pressure environment to encourage more frequent communication. The Web application can also be programmed to send electronic reminders to all caregivers who opt-in to the service requesting that they send a communication to the sufferer, and more particularly to individual caregivers whose frequency of communication has been inadequate relative to a group of caregivers or to predefined expectations.

The valve element of the reed valve is arranged on the side of the second oil reservoir.

The invention relates to a stirring disc screen type feeding machine which comprises a scraping arm and two extruding arms, wherein the scraping arm and the extruding arms are respectively fixedly connected to a spindle; the spindle is driven to rotate by a reduction box; the output flange of the reduction box is fixedly connected to a base, and simultaneously the reduction box is connected to a motor through a belt wheel system; and the front ends of the extruding arms are provided with wear-resisting plates, so that when a material is conveyed to a material barrel and reaches a certain height, the material can be extruded out of the material barrel under the combined action of the wear-resisting plates and a gridding plate arranged on the material barrel. The stirring disc screen type feeding machine is used for easily turning and stirring the material, fully mixing and homogenizing the material, easily gathering the material towards the inner wall of the material barrel and quicklyextruding the material. After the material is extruded out of the material barrel, the material falls onto a collecting plate which rotates under the driving of a reduction motor, thereby conveying the material to a discharging port. The stirring disc screen type feeding machine has the advantages of material stirring function, good mixing and homogenizing effect, small abrasion of extruding arm,long service life, less possibility of material drying, high production efficiency, and the like..

An automatic transmission includes a clutch, a clutch drum, a piston, and a brake. The clutch drum, the clutch, and the brake are arranged in sequence in an interior space formed by joining a transmission case to a rear case in an axial direction from the rear case side. A separating / guiding wall that is provided in a circumferential direction so as to define a surplus lubricating oil trapping space for trapping surplus lubricating oil that gathers on an inner peripheral surface of the transmission case and in a second brake, and causes trapped surplus lubricating oil guided thereby into the surplus lubricating oil trapping space to flow downward in the circumferential direction, and a holding mechanism for restricting axial movement of the separating / guiding wall, are provided in relation to spline fitting portions formed on the inner peripheral surface of the transmission case.

The invention discloses an ecological algae control method for a lake, which comprises the following steps: setting up a fence area at an open water band or a coastal band of the lake, wherein the fence mesh is 3 to 6 centimeters; and throwing 30 to 75 / hectare of siniperca, 30 to 75 / hectare of topmouth culter and 50 to 100 g / m2 of corbicula fluminea into the fence area. The ecological algae control method can filter blue algae, reduce the biomass of algae, reduce the contents of N and P in the water body, cut down the nutrition load of the water body, has lower running cost and good recycling property and operability, and is favorable for long-term cyclic operation.

In the hermetically sealed scroll compressor, an injection pipe for injecting a fluid to a compression chamber is connected to an injecting port of a fixed scroll. The injecting port includes a first injecting port which is provided in the vicinity of a fixed scroll inner curve and injects the fluid to an orbiting outer compression chamber, and a second injecting port 22b which is provided in the vicinity of a fixed scroll outer curve and injects the fluid to a orbiting inner compression chamber 8b. The second injecting port is placed in parallel in a radius direction with respect to the first injecting port and is placed so that an orbiting scroll wrap does not practically communicate with the orbiting outer compression chamber in the state in which the orbiting scroll wrap is in contact with the outer side of a fixed scroll wrap.

The invention belongs to the technical field of ship moon pools, and relates to a ship moon pool structure, in particular to a damping plate structure reducing the surging of fluid in a cavity of a moon pool. The damping plate structure is characterized by comprising a horizontal damping plate and a vertical damping plate; the vertical damping plate and the horizontal damping plate are provided with holes respectively, water flow enters the area between the vertical damping plate and the horizontal damping plate, and then the surging of the water flow is reduced; ventilation pipelines communicated with the outside atmosphere are arranged on the side face of an air cushion area between a moon pool top cover and a free surface in the moon pool. Because the ventilation pipelines communicated with the outside atmosphere are arranged on the side wall of the air cushion area, the pressure of the air cushion area is the same as outside pressure, the waving of water inside the moon pool is synchronized with the waving of water outside a ship as far as possible, and the surging of the water flow is reduced. In this way, the sailing resistance is reduced, and the power consumption of a motor is lowered.
