Opis:
Radioactive aerosols in the confined workplace are a major source of internal exposure hazards for workers. Cloud-type radioactive aerosol elimination system (CRAES) have great potential for radioactive aerosol capture due to their high adsorption capacity, lack of cartridges and less secondary contamination. A CRAES was designed and constructed, and a FeOOH/rGO composite was directly prepared by a hydro-thermal method to characterise and analyse its morphology, chemical structure and removal efficiency for simulated radioactive aerosols. The results show that the FeOOH/rGO composite works in synergy with the CRAES to effectively improve the removal efficiency of simulated radioactive aerosols. A 30-minute simulated radioactive aerosol removal rate of 94.52% was achieved when using the experimentally optimized composite inhibitor amount of 2 mg/L FeOOH/rGO with 0.2 g/L PVA as a surfactant. Therefore, the CRAES coupled with the composite inhibitor FeOOH/rGO has broad application potential for the synergistic treatment of radioactive aerosols.

Opis:
Bim is defined as the pro-apoptotic BH3-only protein of the Bcl-2 family, which is a critical sensor and mediator in the mitochondrial-dependent apoptosis. In a previous work, we have cloned a novel transcript of Bim (GenBank accession number: AY305716) from the fetal brain cDNA, which is widely expressed in some carcinoma tissues and normal human tissues. According to the sequence analysis and the newly-defined nomenclature system of Bim isoforms (Adachi et al., 2005, Cell Death Differ 2: 192), we term it BimSs3 according to its characteristic structure. The subcellular location analysis indicated that the fused protein GFP-BimSs3 is distributed in the whole cell, mainly to the nucleus. Overexpression of BimSs3 in HEK293 cells causes apoptosis (28.16 ± 1.55%) compared to the negative control (5.44 ± 2.63%). It also causes cytochrome c release from the mitochondrial fraction to the cytosolic fraction during apoptosis. Western blotting assay indicates the molecular mass of GFP-BimSs3 is approximately 31.0 kDa (GFP: 27 kDa). Hence the open reading frame of BimSs3 may initiate at the second ATG and encodes a 36 amino-acid peptide with BH3 domain.

Opis:
The purpose of this paper is to solve the problem of low conveying efficiency and serious blade wear during vertical screw conveying of cohesive particles. Firstly, the reliability of DEM simulation was verified by comparing the simulated and theoretical values and the influence regularity of different design parameters (rotational speed, pitch, and clearance) on screw conveying characteristics were analyzed based on DEM. In addition, the effect of design parameters on the screw conveying characteristics is identified by ANOVA. Then, the multi-objective optimization model with the both of maximizing the average mass flow rate and minimizing the maximum wear depth of the blade was established using the polynomial fitting regression, which was solved by the non-dominated sorting genetic algorithm (NSGA-II). Finally, the comprehensive evaluation was used to determine the best design parameters. The above research results provide a certain reference for the study of cohesive particle’s vertical screw conveying characteristics and equipment optimization design.
