EXPRESS: Drawing Individual Images Benefits Recognition Accuracy in the DRM Paradigm

We examined the effects of drawing on correct and false recognition within the Deese/Roediger-McDermott (DRM) false memory paradigm. In Experiment 1, we compared drawing of a word’s referent using either a standard black pencil or colored pencils relative to a read-only control group. Relative to reading, drawing in either black or colored pencil similarly boosted correct recognition and reduced false recognition. Signal-detection analyses indicated that drawing reduced the amount of encoded memory information for critical lures and increased monitoring, indicating that both processes contributed to the false recognition reduction. Experiment 2 compared drawing of individual images of DRM list items relative to drawing integrated images using sets of DRM list items. False recognition was lower for drawing of individual images relative to integrated images—a pattern that reflected a decrease in encoded memory information but not monitoring. Therefore, drawing individual images improves memory accuracy in the DRM paradigm relative to a standard read-control task and an integrated drawing task, which we argue is due to the recruitment of item-specific processing.

Recovery of zinc from zinc oxide dust containing multiple metal elements by carbothermal reduction

A carbothermal reduction process simulating EAF process is used to handle the zinc oxide dust, and the zinc in the dust can be extracted and recovered efficiently. The crude zinc and lead-tin alloy were obtained finally. The effects of temperature, holding time, and reductant dosage on zincvolatilization rate were investigated, and the ?Pelletizing -Calcination-Carbothermic reduction? experiment was conducted. The resultsfound the optimal reduction condition was as follows: the temperature of 1300?C, reductant dosage of 14.04% and holding time of 120 min. After the calcination at 900?C for 120 min, the removal rates of fluorine, chlorine and sulfur in the dust were 98.18%, 96.38% and 28.58% respectively, and the volatilization rate of zinc was 99.83% in reduction process. The zinc content of the crude zinc was 68.48%.

Preparation of Lignite Dust Suppressant by Compound Surfactants and Effect of Inorganic Salt on Dust Suppressant

In order to improve the safety, operability, and cleanability of the dust suppressant, this paper uses the surfactant monomers selected in the previous experiment as the main material formula and adds the inorganic salt as the synergist to prepare the dust suppressant for the PMX. The wetting property of the solution was characterized by the surface tension and contact angle of the pressed coal pieces. The sedimentation experiment was used to screen the compounding system of the surfactant. Finally, the dust suppressant was used to reduce the dust of the PMX in the coal dust simulation system. The results show that (1) the surfactant compounding system can effectively improve the wetting property and the sedimentation time of coal dust. The fast penetration T (0.06%), SDBS (0.15%), and APG (0.20%) are the preferred main ingredients. (2) Adding inorganic salts on the basis of compounding, according to the effect of inorganic salts on the effect of dust suppressant, it is concluded that NaCl (1.00%) is the best synergist. (3) In order to save costs, reduce the amount of surfactant. According to the simulated dust reduction experiment, formula N: anionic surfactant SDBS (0.06%), anionic surfactant fast-permeability T (0.06%), and inorganic salt NaCl (1.00%) are the best for PMX dust fall.

Bully Victimization, Truancy, and Violent Offending: Evidence From the ASEP Truancy Reduction Experiment

Research indicates truancy and being bullied (otherwise called bully victimization) are independently linked to violent offending. We examine the associations between truancy, bully victimization, and violent offending in a sample of young people who participated in the Ability School Engagement Program (ASEP) truancy reduction experiment. Pre-intervention, half of the sample reported missing school because they were being bullied. Experiment and control participants both exhibited significant reductions in bully victimization and missing school because of bully victimization. Neither groups exhibited significant reductions in violent offending. Contrasting expectations, participants in the control group had significantly larger reductions in missing school because of bully victimization. Post-intervention measures of bully victimization were significantly related to higher odds of violent offending. Bully victimization is a critical factor in understanding the nexus between truancy and violent offending which, if neglected in an intervention (like ASEP) can lead to backfire effects for young people.

Study on the Atomization and Dust-Reduction Performance of a New Type of External Pneumatic Vortex Fog Curtain Dust Removal Device in Fully Mechanized Excavation Face

To solve the problem of dust pollution in the heading face, a new type of external pneumatic vortex fog curtain dust removal device suitable for a fully mechanized excavation face is designed in this paper. Firstly, dust migration laws at different times are simulated and analyzed by COMSOL software, and the functional relationship of dust concentration distribution above 50 mg/m3 at different heights and different wind speed is derived. Aiming at the dust migration laws of the heading face, a new dust removal device was proposed, and the atomization performance of the new type of external pneumatic vortex fog curtain dust removal device under different jet wind speed, different atomization pressure, and different nozzle working angle is explored through atomization performance experiment. It is found that when jet wind speed is 30 m/s, atomization pressure is 4 MPa, and nozzle working angle is 75°, the atomization performance of the new type of external pneumatic vortex fog curtain dust removal device is the best. Through the simulation of COMSOL software, the influence of air volume on the new type of external pneumatic vortex fog curtain dust removal device is analyzed. It is found that the new type of external pneumatic vortex fog curtain dust removal device is relatively stable when the air volume at the pressure outlet is less than 400 m3/min. The dust-reduction efficiency of the new type of external pneumatic vortex fog curtain dust removal device was investigated through the dust-reduction experiment, and it is found that the new type of external pneumatic vortex fog curtain dust removal device had better dust removal performance under the condition that the ventilation conditions did not interfere with the integrity of the vortex fog curtain.
