In this paper, the solid solution and precipitation behavior of inclusions on the surface and 1/2 thickness of the tested steel plate under the condition of welding heat input of 400 kJ/cm is investigated by using laser confocal experiments with hot-rolled state DH36 ship plate steel as the research object, and the mechanism of the effect of inclusions on the phase transformation of an acicular ferrite is revealed. The results show that the inclusions of the tested steel are mainly composed of Oxide-MnS, MnS, Oxide, TiN, Spinel, etc. The amount of inclusions on the surface of the tested steel plate is significantly higher than that at the 1/2 thickness position. During the heating stage, the small inclusions on the surface immediately disappeared, and the large inclusions gradually solidified in the matrix; atomic diffusion occurred at the bond between the inclusions and the matrix; while the small inclusions at the 1/2 thickness position gradually disappeared at the beginning of the heating stage, and the inclusions began to precipitate and grow when the temperature was increased to 990 °C. The acicular ferrite preferentially nucleates and grows near the boundary of the inclusions during the post-weld cooling stage, and its growth ends when two acicular ferrites cross.

Background: Telemedicine is beneficial for improving treatment efficiency and reducing medical expenses of cancer patients. This study focuses on cancer patients participating in teleconsultations through a regional telemedicine platform in China, analyzes the consultation process, and provides references for the clinical application of telemedicine. Methods: We collected information on teleconsultations of cancer patients conducted from 2015 to 2022 through the regional telemedicine platform. Utilizing SPSS 23.0 software, we conducted descriptive analysis to summarize the distribution of patient gender, age, region, and disease types. The ordinal logistic regression analysis was adopted to analyze the factors influencing the waiting time and consultation duration for teleconsultations. Results: From 2015 to 2022, a total of 23,060 teleconsultations were conducted for cancer patients via regional telemedicine platform, with an average growth rate of 11.09%. The main types of consultations were for lung cancer, liver cancer, and breast cancer, accounting for 18.14%, 10.49%, and 9.46% respectively. 57.05% of teleconsultations had a waiting time of less than 24 h, while patient age, consultation expert level, and disease type were the main factors influencing the waiting time. 50.06% of teleconsultations had a duration of more than 20 min, and the inviting hospital level and the title of invited consultant were the main factors influencing the consultation duration. Conclusions: In China, telemedicine has been widely employed in the clinical diagnosis and treatment of cancers, covering various types of oncological diseases. However, the waiting time for teleconsultations was generally more than 12 h, indicating the need to enhance consultation scheduling and allocate more expert resources to further optimize the efficiency of teleconsultations. Additionally, further exploration is required for remote health management of outpatients with cancers outside the hospital. [ABSTRACT FROM AUTHOR]

To investigate the effects of different pasteurization processes (85 °C for 20 min and 75 °C for 30 min) on the edible quality and shelf life of white cut chicken, the samples were stored at 0~4 °C for 0-30-40 d, and the pH, color, texture, volatile flavor substances, volatile salt base nitrogen (TVB-N), total number of colonies, and sensory quality were determined. Results indicated that the pH value of white cut chicken treated by pasteurization process was stable, the total colony count was lower, and the generation of TVB-N was lower. After comparing with the control group, neither of the two groups of different treatments of the pasteurization process would have a significant trending effect on the eating characteristics of white cut chicken such as color, hardness and chewiness, and the sensory scores were not significantly different from those of the control group (P>0.05). Meanwhile, this study compared the relative superiority of two different pasteurization processes and demonstrated that the process condition of 85 °C pasteurization treatment for 20 min had a significant effect on inhibiting microbial growth in the product, prolonging the shelf-life of the white cut chicken, and reducing the deterioration of the edible quality of the chicken meat during storage.

To analyze the changes of spoilage bacteria on the carcasses of broiler during the slaughtering of yellow feather broiler, the diversity of spoilage bacteria in the processing environment and on the carcass surface during the efficient slaughter of yellow feather broiler was determined by the plate pouring method and Illumina MiSeq high-throughput sequencing. The results showed that the main contamination procedure for the growth of bacteria of yellow feather broilers was eviscerating, pre-cooling and grading procedure, and the grading scale, in which the grading scale, workers' gloves from grading workshop, pre-cooling tank and workers' gloves from eviscerating manual gloves were contamination sources in the three processes aforementioned. Moreover, grading scale and workers' gloves in the decomposition workshop were the main source of contaminated flora of yellow feather broilers carcasses. The growth rate of total viable counts (TVC) and Pseudomonas on the surface of yellow feather broilers carcasses was as high as 24.13% and 41.27%, respectively. The TVC of yellow feather broilers increased to 4.63 lg(CFU/g) after grading scale and grading workshop worker's hands (P<0.05). Streptococcus, Escherichia and Aeromonas were the main dominant bacteria in yellow feather broilers carcasses after plucking (DM), evisceration (JH) and disinfection (CH). The abundance of Aeromonas increased substantially in yellow feather broilers after pre-cooling, followed by Streptococcus. After the grading scale, Acinetobacter was the dominant bacterium in the yellow feather broilers carcasses, followed by Macrococcus. As the abundance of Aeromonas and Streptococcus decreased significantly on the carcasses of yellow feather broilers treated with slightly acidic electrolyzed water (SAEW), it indicated that the disinfecting effect of SAEW was obvious. The results of the present investigation could provide data support and theoretical reference for environmental control, product quality maintenance and shelf-life extension in yellow feather broilers slaughterhouse by analyzing the microbial distribution during the slaughter of yellow feather broilers.

In this paper, BLDA technology has been applied to realize the preparation of a LTPS TFT without ion implantation. The BLDA LTPS TFT gives the advantages of high mobility (~ 290.5 cm2/Vs), a smaller subthreshold voltage swing, kink‐free output curve, and excellent device stability under PBTS. The backplane technology has been successfully applied in 7.1‐inch Mini‐LED display products, and the lighting effect is uniform. This low‐cost technique is very suitable for the LTPS TFT backplane for large area, high resolution Mini/Micro LED displays. [ABSTRACT FROM AUTHOR]

A techno-functional approach applied to the lithics of the Late Upper Palaeolithic Shizitan 29 site allows the identification of previously unrecognized technical features of microblade pressure production and new behavioral understanding of its evolution beginning ca. 26,000 cal b.p. These technical features may relate to the evolution of so-called boat-shaped cores, including the development of two blade scar sequences and the 8-like contour of the striking platform (likely related to fixing cores in a holding device). Counter to traditional typological lithic analyses centered on final core morphologies, we seek to identify technical objectives related to the required pressure production. In doing so, we argue that earlier semi-conical cores may have maximized the exploitation of the core volume, while subsequent boat-shaped cores developed to maximize the efficiency of the production of straight profile, regular blades. This allowed microblades to become a critical adaptation for final Pleistocene hunter-gatherers in northern East Asia. [ABSTRACT FROM AUTHOR]
