A quasiexperimental design was adopted in this study, and 90 4th graders in a district of Taichung City were selected. Forty-five sample students were defined as the treatment group, and the 45 belonged to the control group. A ten-week teaching experiment was conducted on the treatment group, while didactic e-book teaching was done on the control group. The data of pre-test and post-test scores from the listening & reading comprehension test were aimed at analyzing students’ English learning achievement. At the end of the teaching experiment, the data of Instructional Materials Motivation Scale were collected to examine the difference in students’ learning motivation. The conclusions are as follows. 1. By applying “Cool English” online teaching materials to English instruction, students’ learning achievement of both listening and reading could be improved. For the scores of the listening and reading test, the treatment group was higher than the control group. There is a significant difference between two groups, but there is no significant difference when statistically testing the listening scores and reading comprehension scores respectively. 2. There is a significant difference in the learning achievement of both groups, as all students were instructed by using computers and information technology. 3. There is no significant difference in students’ whole learning motivation, but there is a significant difference in two motivational factors: “attention” and “satisfaction”. Finally, the findings of this study offer some evidence for reference for English teachers at elementary schools who want to apply e-Learning resources to their instruction.

AIM: One of the important characteristics of the occurrence and development of triple-negative breast cancer(TNBC) is dysregulated cell metabolism. The aim of this study is to investigate the mechanism of pyruvate dehydrogenase E1 subunit alpha 1（PDHA1), a key enzyme component in aerobic glycolysis, affecting the proliferation, metastasis and invasion of TNBC. METHODS：（1) The expression levels of PDHA1 in breast cancer tissues and adjacent tissues were analyzed by UALCAN database, KM-plotter database, Gene MANIA database and TCGA database. The expression of PDHA1 was compared according to tumor pathological stage, subtype classification and breast cancer bio‑ markers. The function of PDHA1 in TNBC was explored by gene enrichment analysis.(2) Immunohistochemistry assays were used to detect the expression of PDHA1 in human TNBC tissue and adjacent tissue samples.(3) Stable PDHA1 knockout and PDHA1 rescue TNBC MDA-MB-231 cells were constructed. The proliferation of MDA-MB-231 cells was detected by colony formation assay and cell counting assay. The regulatory effect of PDHA1 on the invasion and migration of MDA-MB-231 cells was detected by in vitro scratch assay and Transwell migration assay. RESULTS: Database analysis showed that the group with high PDHA1 expression in breast cancer had shorter survival and worse prognosis. In clinical specimens, the expression of PDHA1 in cancer tissues was higher than that in adjacent normal tissues. Knockout of PDHA1 inhibited the proliferation, metastasis, invasion and epithelial-mesenchymal transition of MDA-MB-231 cells. CONCLUSION： PDHA1 is overexpressed in TNBC, and it promotes cell proliferation and facilitates TNBC metastasis through the epithelial-mesenchymal transition pathway. [ABSTRACT FROM AUTHOR]

Objective To investigate the epidemiological characteristics and pathogen detection results of food-borne diseases among children in Chongqing, and to provide scientific basis for the prevention of infectious diarrhea in children. Methods From 2019 to 2021, fecal samples of food-borne diseases collected by Children's Hospital of Chongqing Medical University were detected for Salmonella, Vibrio parahaemolyticus, Shigella, diarrhea Escherichia coli and Norovirus, and the results were analyzed. Results From 2019 to 2021, a total of 438 cases of food-borne diseases were reported and 126 positive samples were detected from a total of 354 feces samples, with a detection rate of 35. 59%. The pathogens were 103 strains of Salmonella (29. 10%), three strains of diarrhea Escherichia coli (0. 85%), 33 strains of Norovirus (9. 32%), no Shigella and Vibrio parahaemolyticus were isolated, and 13 cases of pathogenic bacteria combined with Norovirus infection (3. 67%). The cases were mainly concentrated in the age group less than or equal to five years old, and the positive samples were mostly concentrated in the age group less than or equal to two years old, accounting for 82. 08% (food-borne pathogens) and 84. 85%(Norovirus) of the total positive samples. Most of the suspected food came from home-made food, accounting for 71. 92% of all cases. Conclusion Salmonella and Norovirus are the main pathogens of food-borne diseases among children in Chongqing. So food safety education and health education should be strengthened, and food-borne disease prevention and control knowledge should be publicized to reduce the occurrence of food-borne diseases.

The winding and core of amorphous alloy transformer generally adopt rectangular structure. The unbalanced temperature rise caused by operating loss is more likely to lead to winding insulation deterioration and affect the reliability of power supply. For the special winding structure of amorphous alloy transformer, the temperature rise of amorphous alloy transformer winding was analyzed and calculated, and the hot spot temperature was predicted, which had theoretical guiding significance for the design optimization and operation control of rectangular winding structure transformer. Based on the three-dimensional magnetic-thermal-flow multi-physics coupling simulation and temperature rise test, a three-phase oil-immersed amorphous alloy distribution transformer with SBH15-M-200/10 was taken as the research object. The operation characteristics under rated load were analyzed, and the hot spot temperature of each winding was simulated. The correctness of the simulation results was verified by short-circuit temperature rise test. The results show that the relative error between the hot spot temperature of amorphous alloy transformer winding calculated by three-dimensional magnetic-thermal-flow multi-physical field coupling and the temperature rise test results is not more than 5%. The hot spot temperature of amorphous alloy transformer winding studied appears in the middle and upper part of phase B low voltage winding, and the hot spot temperature reaches 64.77 ℃.

Turbochargers are widely used in internal combustion engines. The floating ring bearing is the most important part in the turbocharger, which is composed of inner film and outer film. The floating ring bearing can reduce the frictional power and oil film temperature. In the past, the lubrication performances of the floating ring bearing were analyzed without considering the heat transfer among the shaft, floating ring and bearing block. Furthermore, some researchers analyzed the lubrication performance of floating ring and the ring speed ratio separately. In reality, there exists heat transfer among the shaft, floating ring and bearing block and this part of heat will directly influence the lubrication performance of the floating ring. Besides, the change of the structural parameters may decrease ring speed ratio, which maybe is unfavorable to the practical operation if it is too small, and the change of the ring speed ratio may also influence the lubrication performance. So there exists a strong coupled relationship between the lubrication performance and ring speed ratio, and they can be studied more comprehensively and systematically with the change of structural parameters. The lubrication performance of floating ring bearing and the floating ring speed ratio in turbocharger were studied by considering the heat transfer among the shaft, floating ring and bearing block. Based on the Reynolds equation and the floating ring balance equation, the lubrication model of floating ring bearing was established. The Reynolds equation was solved by the finite difference method. The thermal deformation of the floating ring bearing was calculated by the thermal deformation equation. Comparative analysis on the influence of structural parameters on lubrication performance of floating ring bearing and floating ring speed ratio was performed, and the parameters included inner film clearance, outer film clearance, inner circle radius and outer circle radius. Results showed the effect and affecting level of structural parameter on lubrication performance and floating ring speed ratio should be considered comprehensively. The ring speed ratio decreased with the increase of inner film clearance. Compared with that inner film clearance is 0.02 mm, the ring speed ratio decreased 23% when inner film clearance is 0.04 mm. The inner film temperature, the outer film temperature decreased and the total friction power loss slightly increased with the increase of inner film clearance. The lubrication performance and ring speed ratio are ideal when inner film clearance is 0.03 mm. Compared with that outer film clearance is 0.04 mm，the ring speed ratio increased more than 30%. The outer film temperature decreased with the increase of outer film clearance. The higher the rotation speed, the greater the decrease amplitude of the outer film temperature. The smaller the inner circle radius, the smaller the floating ring speed ratio, and the smaller the inner film temperature, outer film temperature and total friction power loss. So the lubrication performance of the floating ring bearing will be improved with the decrease of the inner circle radius. The ring speed ratio decreased with the increase of the outer circle radius. But the inner film temperature, the outer film temperature increased, the total friction power loss and total oil leakage flowrate changed less than 5% with the increase of the outer circle radius. The outer circle radius has little effect on the lubrication performance of the floating ring bearing. Compared with the adjustment of the outer circle radius, it is more effective to improve the lubrication performance of floating ring bearing with the adjustment of the inner circle radius. There is a good agreement between the results predicted by the calculation model in this paper and some published experimental data. [ABSTRACT FROM AUTHOR]
