Heat transfer performance of supercritical CO2 in a vertical U-tube

Supercritical carbon dioxide (sCO2) is taken as an excellent working medium for efficient and compact energy conversion devices. However, heat transfer performance (HTP) of sCO2 in a vertical U-tube is intricate owing to dramatic variation of its temperature-dependent thermophysical properties. In this study, flow and heat transfer performance (FHTP) of sCO2 in a vertical U-tube is studied with an improved shear stress transfer model. Additionally, the impacts of operational parameters (heat flux q, mass flux G and pressure P), flow directions and bending diameters (dbend) of U-tube on FHTP are investigated. In both directions, the differences in local pressure drop caused by buoyancy effect and thermal expansion are analyzed deeply. The results demonstrate that the bend section can disturb flow and vortexes persist in downstream, thus improve the HTP. However, an apparent heat transfer deterioration zone can be observed in the ascending section. Under both directions, the average heat transfer coefficient (havg) raises with the growing G and P and decreasing q and dbend, while the total pressure drop (ΔPtotal) rises with the raising G and q as well as decreasing P. Moreover, the U-tube with down-up direction obtains higher havg and lower ΔPtotal than up-down.

Gaging "JoJo Rabbit " Skies - Film Deconstruction and Reshaping of Literature

In contemporary film and television, many creative works use excellent literary works as the basis of adapted scripts. Many not-so-excellent literary works have been adapted into film and television works that the audience knows and loves. Adapting literary works into film and television has always occupied a significant position in film history. This article will compare JoJo Rabbit and the original novel Gaging Skies to explore the adaptation of movies based on literary works that align with human ethics in today's social environment and the successful deconstruction of literature by film. And reinvention. This article elaborates on the expression of the theme in JoJo Rabbit from multiple dimensions, such as the comparison between the script and the original work, the current situation of film adaptations, and the excellent use of audio-visual language in the film. Finally, a multi-angle comparison of the original novel and the film summarizes how the film deconstructs and reshapes the literary adaptation of the original work and the profound impact of scholarly works on adapters.

Exceptional combination of mechanical properties and cavitation erosion-corrosion resistance in a Fe23.7Co23.8Ni23.8Cr23.7Mo5 multi-principal element alloy

This study analyzed cavitation erosion (CE) and cavitation erosion-corrosion (CE-C) of single-phase face-centered cubic structured Fe23.7Co23.8Ni23.8Cr23.7Mo5 multi-principal element alloy (MPEA) with varying grain sizes obtained through post-deformation annealing (PDA). The average grain sizes of the samples after annealing at 1100 °C for 60 s, 1150 °C for 60 s, and 1100 °C for 200 s are 4.1 µm, 10.3 µm, and 15.2 µm, respectively. Among them, the 4.1 µm sample exhibits the best combination of high ultimate tensile strength (889 MPa) and large elongation (40.3%), as well as good electrochemical corrosion resistance in NaCl solution. Under the conditions of CE and CE-C for a duration of 10 h, the 4.1 µm specimen exhibits cumulative mass losses of approximately 1.4 mg and 2.6 mg, respectively. In contrast, under identical conditions, the 316 L SS registers cumulative mass losses of approximately 16.7 mg and 24.8 mg, respectively. Due to the excellent mechanical properties and work hardening ability of the 4.1 µm sample, it can effectively resist the plastic deformation caused by cavitation erosion, reducing mass loss. In addition, the stable passivation film enhances its resistance to Cl- destruction, thus demonstrating notable corrosion resistance. Ultimately, under conditions where cavitation erosion and corrosion coexist, these combined properties enable the 4.1 µm sample to exhibit the least mass loss and damage.

The Influence of Various Welding Methods on the Microstructure and Mechanical Properties of 316Ti Steel.

Austenitic stainless steels are very popular due to their high strength properties, ductility, excellent corrosion resistance and work hardening. This paper presents the test results for joining AISI 316Ti austenitic steel. The technologies used for joining were the most popular welding techniques such as TIG (welding with a non-consumable electrode in the shield of inert gases), MIG (welding with a consumable electrode in the shield of inert gases) as well as high-energy EBW welding (Electron Beam Welding) and plasma PAW (plasma welding). Microstructural examinations in the face, center and root areas of the weld revealed different contents of delta ferrite with skeletal or lathy ferrite morphology. Additionally, the presence of columnar grains at the fusion line and equiaxed grains in the center of the welds was found. Microstructural, X-ray and ferroscope tests showed the presence of different delta ferrite contents depending on the technology used. The highest content of delta ferrite was found in the TIG and PAW connectors, approximately 5%, and the lowest in the EBW connector, approximately 2%. Based on the tests carried out on the mechanical properties, it was found that the highest properties were achieved by the MIG joint (Rm, 616, Rp0.2 = 335 MPa), while the lowest were achieved by the PAW joint (Rm = 576, Rp0.2 = 315 MPa).

Implementation of Step-Down Intermediate Care (IC) in Buckinghamshire, UK: A Qualitative Evaluation Study of Healthcare Professionals’ Experiences and Perspectives

Step-down intermediate care aims to offer short-term care for people who are medically optimised for discharge but needing a period for further assessment and/or rehabilitation. The aim of this study, which was nested in a larger evaluation project, was to explore the experiences and perspectives of healthcare professionals to understand the implementation of a step-down IC service in Buckinghamshire, UK. The evidence is used to inform the service providers of what elements worked well and what areas require improvement. A qualitative study using semistructured interviews was conducted in May 2022. Ten healthcare professionals participated. Interviews were transcribed verbatim and reflexive thematic analysis was used to analyse the data. The following five core themes were developed: (1) the developmental period of step-down IC, (2) providing care together, (3) perceived functions of the integrated hub, (4) communication, and (5) resources. Findings from the interviews highlighted the excellent working relationships among healthcare professionals from different disciplines, which contributed to their job satisfaction and the efficiency of the service. In addition, healthcare professionals stressed the importance of the integrated hub, as it facilitated the communication between the teams and speeded up the decision-making. Several organisational challenges, such as communication issues, healthcare professionals’ capacity, and the need for further funding were also voiced. Involving staff in the evaluation of a step-down intermediate care service has provided useful information on the service’s implementation process and will inform the development of a long-term strategy for intermediate care.

Large-scale hierarchically porous polydopamine loaded rattan-based solar evaporator with high stability to salinity changes

As a convenient photothermal material, polydopamine (PDA) has been widely utilized in wood-based evaporators. However, the loading conditions of polydopamine on biomass bulk materials have not been systematically studied. In this paper, the suitable reaction conditions of polydopamine were studied with rattan as the substrate, and a reference for the improvement of the loading conditions was proposed. The polydopamine-loaded rattan-based evaporator (PDA-R) prepared on this basis exhibits excellent working stability due to the unique large-scale hierarchical porous structure of rattan. In addition to excellent salt resistance and cycle performance (evaporation rate decays by 5.1% after 30 cycles), the larger-aperture channel (200–450 μm) also brings better adaptability to salinity changes than polydopamine-loaded basswood-based evaporator (PDA-BW) (the attenuation coefficient of PDA-R is 6.2%, while the attenuation coefficient of PDA-BW is 16.3%). All of these indicate the broad prospects of polydopamine-loaded rattan-based evaporator as a multi-effect treatment scheme of brine.

Time Predictable Modeling Method for GPU Architecture with SIMT and Cache Miss Awareness

Graphics Processing Units (GPUs) are used to accelerate computing-intensive tasks, such as neural networks,data analysis, high-performance computing, etc. In the past decade or so, researchers have done a lot of work on GPU architecture and proposed a variety of theories and methods to study the microarchitectural characteristics of various GPUs. In this study, the GPU serves as a co-processor and works together with the CPU in an embedded real-time system to handle computationally intensive tasks. It models the architecture of the GPU and further considers it based on some excellent work. The SIMT mechanism and Cache-miss situation provide a more detailed analysis of the GPU architecture. In order to verify the GPU architecture model proposed in this article, 10 GPU kernel_task and an Nvidia GPU device were used to perform experiments. The experimental results showed that the minimum error between the kernel task execution time predicted by the GPU architecture model proposed in this article and the actual measured kernel task execution time was 3.80%, and the maximum error was 8.30%.

MXene/AlGaN van der Waals heterojunction self-powered photodetectors for deep ultraviolet communication

Self-powered deep ultraviolet (DUV) photodetectors (PDs) have attracted considerable attention in environmental, industrial, and military fields because of their power-independent and environmentally sensitive photodetection. However, DUV PDs based on traditional thin film structures are limited by the low intrinsic mobility of aluminum-gallium nitride (AlGaN) and the large barrier width of the heterogeneous structure, which makes it difficult to achieve efficient spontaneous separation, resulting in lower responsiveness and a slow response speed. Herein, a 2D/3D DUV PD based on the MXene, niobium carbide (Nb2CTx)/AlGaN van der Waals heterojunctions (vdWHs) has been proposed. The as-prepared DUV PDs revealed self-powered properties with a high responsivity of 101.85 mA W−1, as well as a fast response (rise/decay time of 21/22 ms) under 254 nm DUV illumination, thanks to the excellent electrical conductivity and tunable work function of the MXene. It also showed a large linear dynamic range of 70 dB under −2 V bias because of the strong DUV absorption of MXene/AlGaN vdWH, and the enhanced carrier mobility under high illumination density. This study presents an easy processing route to fabricate high-performance self-powered DUV PDs based on MXene/AlGaN vdWHs for DUV communication.

Covering variable precision fuzzy rough sets based on overlap functions and the application to multi-label classification

Fuzzy rough sets (FRSs) play a significant role in the field of data analysis, and one of the common methods for constructing FRSs is the use of the fuzzy logic operators. To further extend FRSs theory to more diverse information backgrounds, this article proposes a covering variable precision fuzzy rough set model based on overlap functions and fuzzy β-neighbourhood operators (OCVPFRS). Some necessary properties of OCVPFRS have also been studied in this work. Furthermore, multi-label classification is a prevalent task in the realm of machine learning. Each object (sample or instance) in multi-label data is associated with various labels (classes), and there are numerous features or attributes that need to be taken into account within the attribute space. To enhance various performance metrics in the multi-label classification task, attribute reduction is an essential pre-processing step. Therefore, according to overlap functions and fuzzy rough sets’ excellent work on applications: such as image processing and multi-criteria decision-making, we establish an attribute reduction method suitable for multi-label data based on OCVPFRS. Through a series of experiments and comparative analysis with existing multi-label attribute reduction methods, the effectiveness and superiority of the proposed method have been verified.

Mixed method evaluation of a learning from excellence programme for community health workers in Neno, Malawi

BackgroundCommunity Health Workers (CHWs) play an essential role in linking communities to facility-based healthcare. However, CHW programmes have often been hampered by low levels of staff motivation, and new tools aimed at improving staff motivation and work environment are needed. One such intervention is the “Learning from Excellence” (LfE) programme. We aimed to assess feasibility, outputs, and impact of a co-designed LfE programme on CHW motivation, in Neno District.MethodsWe conducted a convergent mixed-method evaluation of the LfE programme. Co-design of the programme and forms took place between October 2019 and January 2020. LfE forms submitted between September and November 2020 were analysed using descriptive statistics and memos summarising answers to the open-ended question. To investigate experiences with LfE we conducted in-depth semi-structured interviews with key stakeholders, CHWs, and site supervisors, which were analysed thematically. A pre-post intervention questionnaire was developed to assess the impact of the co-designed LfE intervention on CHW motivation and perceived supervision. Outcomes were triangulated into a logic model.ResultsIn total 555 LfE forms were submitted, with 34.4% of CHWs in Neno District submitting at least one LfE report. Four themes were identified in the interviews: LfE implementation processes, experience, consequences, and recommendations. A total of 50 CHWs participated in the questionnaire in January 2020 and 46 of them completed the questionnaire in December 2020. No statistically significant differences were identified between pre-and post-LfE measurements for both motivation (Site F: p = 0.86; Site G: p = 0.31) and perceived supervision (Site F: p = 0.95; Site G: p = 0.45). A logic model, explaining how the LfE programme could impact CHWs was developed.ConclusionsMany CHWs participated in the LfE intervention between September 2020 and November 2020. LfE was welcomed by CHWs and stakeholders as it allowed them to appreciate excellent work in absence of other opportunities to do so. However, no statistically significant differences in CHW motivation and perceived supervision were identified. While the intervention was feasible in Neno District, we identified several barriers and facilitators for implementation. We developed a logic model to explain contextual factors, and mechanisms that could lead to LfE outcomes for CHWs in Neno District. The developed logic model can be used by those designing and implementing interventions like LfE for health workers.

Advances in the Stability of Catalysts for Electroreduction of CO2 to Formic Acid.

The electroreduction of CO2 to high-value products is a promising approach for achieving carbon neutrality. Among these products, formic acid stands out as having the most potential for industrialization due to its optimal economic value in terms of consumption and output. In recent years, the Faraday efficiency of formic acid from CO2 electroreduction has reached 90~100 %. However, this high selectivity cannot be maintained for extended periods under high currents to meet industrial requirements. This paper reviews excellent work from the perspective of catalyst stability, summarizing and discussing the performance of typical catalysts. Strategies for preparing stable and highly active catalysts are also briefly described. This review may offer a useful data reference and valuable guidance for the future design of long-stability catalysts.

Training and Development, Work Performance, and Social Capital Constructs of Library Personnel in the South Manila Educational Consortium

Libraries play a crucial role in promoting information access and intellectual growth. To ensure library personnel thrive and meet diverse client needs, it is essential to understand their professional development and performance. There is insufficient research in a library working environment that integrates training and development, work performance, and social capital among personnel into a unified paradigm. This study is being carried out in this context to assess all three variables from library personnel and the findings will serve as a basis for improving training and development programs, enhancing work performance, and fostering social capital among library personnel, thus leading to informed decision-making processes related to human resource development and organizational strategy for optimizing library personnel performance and promoting a conducive working environment. The study utilized descriptive quantitative methodology, collecting data through a structured survey questionnaire from the South Manila Educational Consortium Libraries. Sixty-one (61) questionnaires were completed and returned from the total population, and SPSS was used for analysis, interpretation, frequency distribution, percentages, and mean. The findings showed that seminars, conferences, and workshops were the most available and widely used interventions of the respondents. The study also found that inadequate funding hinders training and development, with library funding being a key strategy to enhance them. Furthermore, respondents demonstrated above-average task and contextual performance, excellent counterproductive work behavior, and high levels of structural, relational, and cognitive social capital. Based on the notable results, it becomes evident that the training and development interventions of respondents were not significantly available. Additionally, it was observed that most of the library personnel made full use of the available interventions. Also, the study discovered positive work performance and the presence of social capital in the examined population.

Semantic segmentation of remote sensing images based on multiscale features and global information modeling

The main difficulties in semantic segmentation of remote sensing images include the effect of shadows, the blurring of feature differences between categories, and loss of small-scale category features during processing. To deal with these challenges, we propose a semantic segmentation network for RSI based on multi-scale features and global information modeling. A skillfully designed two-branch fusion attention based on an adaptive fusion converter is added to the multilevel cascaded HRNet structure to better combine multiscale features and global modeling information. Prior to this, “Coordinate attention” was combined with “Spatial attention” designed in this paper to form a Feed-forward Attention Layer (FAL) to encode finer feature information cues. Meanwhile, a more refined multilayer decoder is designed to obtain better image category recovery. Various experiments were conducted on four different scenarios and types of datasets including WHDLD, Potsdam, Vaihingen, and LoveDa, and in terms of the significant evaluation metric MIOU, with dividing the training, validation, and test sets in the ratio of 6:2:2, the performance of our model on the above four datasets was obtained with 61.79%, 70.79%, 81.15%, and 52.55%.In addition, a comparison with other excellent works is made and the results show that our designed model has better performance.

Large electrocaloric effect and wide working area in the transition from ferroelectric to nanodomains

AbstractA large adiabatic temperature change along with a wide operating temperature region is usually required for the electrocaloric materials to fulfill their refrigeration function. In general, doping foreign ions into BaTiO3 is the frequently utilized strategy in order to obtain excellent electrocaloric materials for the practical application. In the current paper, BaTiO3 lead‐free ferroelectric ceramics were doped by Ca2+ and Sn4+ simultaneously in order to generate a coexistence state at room temperature, where ferroelectric domains and nanodomains exit. As a result, a large polarization and a wide operating temperature range were finally induced. It is found that Ba0.9Ca0.1Ti0.85Sn0.15O3 has a maximum adiabatic temperature change of 0.85 K and an excellent working temperature region (65 K, ∆T > 90% Tmax) was achieved under an electric field of 50 kV/cm. The above phenomenon indicates that the modified BaTiO3 ceramics can be a good potential electrocaloric material in the state of cross‐existence of ferroelectric domains and nanodomains.

Comparative Analysis of the Differences in Aria Melodies at Different Stages of Chinese National Operas

Since the New Culture Movement, Chinese national opera has been developed by generations of composers, giving birth to a large number of excellent operatic works. Chinese national opera, based on traditional Chinese musical elements, and at the same time borrowing the advanced Western experience in opera composition and creative techniques, is deeply loved by the Chinese public. Adopting the methodological framework of comparative study, this thesis selects six operas from three different stages of Chinese national opera, and chooses representative vocal excerpts with rich musicality for research. Based on the analysis of the existing literature and the musicality of the pieces, this thesis aims to comprehensively illustrate the differences of the chant melodies in the Chinese folk opera works of different stages from different levels and dimensions (e.g., melodic ranges, modal tonalities, musical elements, rhythms, etc.), so as to provide methodological frameworks and conclusions for more in-depth studies by scholars in the future.
