    Opis:
    The study is trying to use ATS (Affective Tutoring System) with emotional calculating technology in the activity of the shell education program. The result is used to study the academic achievement of students with different cognitive styles and system usability. There were 61 fifth-grade children from two different classes participating in this experiment. Every child had to do GEFT (Group Figure-Embedded Test) and academic achievement pre-test before they started the ATS. Then students engaged in ATS learning. Academic achievement post-test was done and the System Usability Scale for Learning Questionnaire after they finished the ATS. The experiment yielded the following results: (1) Learning with ATS not only can give learners an excellent feeling of system usability, but also help learners to promote academic achievement more effectively. (2) According to the system usability and academic achievement, the Field-independent learners were acting better than the Field-dependent learners.

    Opis:
    ZSM-5 synthesized by the hydrothermal method from raw kaolin clay was used as support to prepare TiO2/ZSM-5 catalysts via the sol-gel method. All prepared samples were characterized by X-ray fluorescence spectrometry (XRF), X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier transform infrared (FT-IR), ultraviolet-visible spectroscopy (UV-Vis), transmission electron microscopy (TEM), particle size analysis and surface area measurement. The photocatalytic performance of TiO2/ZSM-5 was investigated based on rhodamine B (RhB) removal under UV radiation (450-600 nm. The results showed that the kaolin clay was successfully transformed into ZSM-5. The BET surface area and pore size distribution of the synthesized ZSM-5 were 364 m2/g and 0.54 nm, respectively. SEM and TEM revealed that TiO2 nanoparticles were well distributed on the surface of ZSM-5. The composite TiO2/ZSM-5 catalyst showed 98.53% removal, which is higher than that of pure TiO2 (80.13%) due to adsorption and degradation of RhB (5.0 mg/dm3) under 60 min UV light irradiation at 1 g/dm3 photocatalyst loading. The synergistic effect of TiO22 and ZSM-5, including adsorption, conduction band electron (e-), and valence-band holes (h+), makes the composite superior to pure TiO2, showing its potential for the degradation of organic dye.

    Opis:
    There lacks an automated decision-making method for soil conditioning of EPBM with high accuracy and efficiency that is applicable to changeable geological conditions and takes drive parameters into consideration. A hybrid method of Gradient Boosting Decision Tree (GBDT) and random forest algorithm to make decisions on soil conditioning using foam is proposed in this paper to realize automated decision-making. Relevant parameters include decision parameters (geological parameters and drive parameters) and target parameters (dosage of foam). GBDT, an efficient algorithm based on decision tree, is used to determine the weights of geological parameters, forming 3 parameters sets. Then 3 decision-making models are established using random forest, an algorithm with high accuracy based on decision tree. The optimal model is obtained by Bayesian optimization. It proves that the model has obvious advantages in accuracy compared with other methods. The model can realize real-time decision-making with high accuracy under changeable geological conditions and reduce the experiment cost.

    Opis:
    This work presents a high-sensitivity refractive index and salinity sensor by using fiber-optic side-polishing and electron-beam evaporation techniques. Thin film coated on the flat surface of side-polished fibers can generate a lossy mode resonance (LMR) effect. A gallium-doped zinc oxide (GZO) thin film was prepared by an electron-beam evaporation with the ion assisted deposition method. The residual thickness of the side-polished fiber was 76.5 μm, and GZO film thickness of 69 nm was deposited on the flat surface of the side-polished fiber to fabricate LMR-based fiber sensors. The variation in the optical spectrum of LMR-based fiber sensors was measured by different refractive index saline solutions. The LMR wavelength shift is caused by the refractive index change, which is nearly proportional to the salinity. The corresponding sensitivity of the proposed fiber-optic sensor was 3059 nm/RIU (refractive index unit) for the refractive index range of 1.333 to 1.398. To evaluate the sensitivity of LMR salinity sensors, the saline solution salinities of 3.6%, 7.3%, 10.9%, 14.6%, 18.2% and 21.9% were measured in this work. The experimental result shows that the sensitivity of the proposed salinity sensor is 9.94 nm/%.

    Opis:
    Airborne pathogens are the most important factor causing environmental issues on pig farms. Research on airborne swine-derived microbes has mainly concentrated on several specific microbes or pathogens. The present work was conducted to detect and identify the entire microbial community in piggery air and their dispersion by 16SrRNA sequencing. Fifteen faeces and eighty-four air samples were collected in swine barns and from different distances away from the barns, respectively. The results showed that the faeces and air share the most dominant bacteria. The top 10 genera belonged to Fimicutes, Proteobacteria and Bacteroidetes, and accounted for 54% and 76-84% of the total sequences. Moreover, great higher (P < 0.01) microbial diversity was detected in the faeces. This study indicated that a hygienic interval of 50 m should be set on swine farms to prevent the spreading infectious disease caused by airborne pathogens.

    Opis:
    In this study, we investigated the effect of the hydrophilic ethylene oxide chain lengths (i.e., degree of polymerization) of nonylphenol polyoxyethylene ether (NPEO-x, x = 8, 10, and 12) on the dewatering of low-rank coal slime through dewatering and adsorption experiments and X-ray photoelectron spectroscopy (XPS) measurements. The dewatering experiments showed that the adsorption of NPEO changed the water content of the low-rank coal slime: NPEO-8 achieved the best effect, followed, in decreasing order, by NPEO-10 and NPEO-12. Adsorption experiments revealed that the adsorption isotherms of NPEO-x on the low-rank coal surface conform with the Langmuir model, and its adsorption kinetics follow the pseudo-second-order kinetic equation. Furthermore, the adsorption is a spontaneous process and controlled by both intraparticle diffusion and liquid film diffusion. The XPS results showed that the adsorption of NPEO-x decreased the content of oxygencontaining groups and, thus, improved the hydrophobicity of the low-rank coal surface. Further, the use of NPEO-x with a low degree of polymerization (x = 8) improves the hydrophobicity of the coal surface and decreases the water content of low-rank coal slime.

    Opis:
    The overall acoustic echo of a submarine is greatly dependent on the conning tower. For enhancing the acoustic stealth performance of a submarine, it is necessary to research an innovative design scheme of the conning tower to reduce its target strength (TS). The aim of this work is to reduce the TS of a conning tower by varying its geometry and streamlining. The accuracy in modelling the acoustic scattering of a conning tower using the Kirchhoff approximation (KA) was validated, compared with finite element analysis (FEA). Several angular conning tower geometries were designed to analyze the effect of streamlining and the number of lateral facets on TS using the KA method. In consideration of the actual situation, the acoustic effect of backing medium was analyzed by compared water-filled elastic hulls with rigid hulls. From the observed TS calculation results, it is shown that the non-streamlined four lateral-facet conning tower geometries are optimal for acoustic stealth performance during the range of incidence angles from −10° to 10°, whereas the streamlined versions have better performance at incidence angles beyond this range. Furthermore, elastic hulls and rigid hulls provide similar spatial distribution regularities in monostatic configuration with the rigidity affecting the magnitude of the TS.

    Opis:
    Effective recognition of tags in the dynamic measurement system would significantly improve the reading performance of the tag group, but the blurred outline and appearance of tag images captured in motion seriously limit the effectiveness of the existing tag group recognition. Thus, this paper proposes passive tag group recognition in the dynamic environment based on motion blur estimation and improved YOLOv2. Firstly, blur angles are estimated with a Gabor filter, and blur lengths are estimated through nonlinear modelling of a Generalized Regression Neural Network (GRNN). Secondly, tag recognition based on YOLOv2 improved by a Gaussian algorithm is proposed. The features of the tag group are analyzed by the Gaussian algorithm, the region of interest of the dynamic tag is effectively framed, and the tag foreground is extracted; Secondly, the data set of tag groups are trained by the end-to-end YOLOv2 algorithm for secondary screening and recognition, and finally the specific locations of tags are framed to meet the effective identification of tag groups in different scenes. A considerable number of experiments illustrate that the fusion algorithm can significantly improve recognition accuracy. Combined with the reading distance, the research presented in this paper can more accurately optimize the three-dimensional structure of the tag group, improve the reading performance of the tag group, and avoid the interference and collision of tags in the communication channel. Compared with the previous template matching algorithm, the tag group recognition ability put forward in this paper is improved by at least 13.9%, and its reading performance is improved by at least 6.2% as shown in many experiments.

    Opis:
    Objectives: To investigate the association between polymorphisms in the p53 pathway genes and chromosomal damage in vinyl chloride (VC)-exposed workers. Materials and Methods: Cytokinesis block micronucleus test was performed in 310 VC-exposed workers and 149 non-exposed workers to determine chromosomal damage. The polymerase chain reaction and restriction fragment length polymorphism technique were used to detect six SNPs in the p53 pathway genes involved in the cell cycle. Results: There was a highly significant dose-response relationship between VC exposure and chromosomal damage. Individuals carrying the variant genotypes were at higher risk for chromosomal damage compared with their wild type genotype: p53rs1042522, MDM2 Del1518rs3730485, MDM2rs2279744 and GADD45Ars532446. On the other hand, individuals possessing the variant genotype of CDKN2A rs3088440 had significantly decreased risk compared with the corresponding wild-type. Conclusions: Genetic polymorphisms in P53 pathway genes may have an impact on VC-induced chromosomal damage.
