Background: Patients after orthopedic surgery often experience the pain, anxiety, depression, and sleep disturbances, which can be greatly reduced by non-pharmacologic interventions as alternative therapies. Randomized controlled trials of nonpharmacologic interventions for anxiety, depression, sleep quality, and pain in patients after orthopedic surgery have been reported, but the results may be conflicting. Evidence to determine the optimal non-pharmacological intervention with a high efficacy is limited. This study aims to assess the effects of non-pharmacologic interventions on the bone anxiety, depression, sleep quality, and pain in patients after orthopedic surgery through a network meta-analysis, thus providing guidance in clinical application. Methods: A systematic search of randomized controlled trials reporting the effects of non-pharmacological interventions on anxiety, depression, sleep quality and pain after orthopedic surgery published before October 2021 will be searched in Wanfang, VIP Information Chinese Journal Service Platform, China National Knowledge Infrastructure, Chinese BioMedicine Literature Database, Pubmed, Embase, Cochrane, and Web of science. Two reviewers will be independently responsible for study selection, quality appraisal, and data extraction. Stata 14.0 software will be used to perform the network meta-analysis. Results: The findings of this research will be reported in a recognized journal. Conclusion: This meta-analysis will provide the stronger evidence for non-pharmacological interventions on alleviating bone anxiety, depression, sleep quality, and pain in patients after orthopedic surgery, which will help clinicians and decision makers in their choices.

BiOI powder has been proved to be an efficient photocatalyst, but the difficulty in removing it from water after reaction limits its application in real water treatment. To solve this problem, a thin-film fixed-bed reactor (TFFBR) was set-up by developing a BiOI thin film on glass fiber cloth (GFC). The composition and structure of the as-prepared films were characterized with X-ray diffraction, X-ray photoelectron spectroscopy, field emission microscopy, transmission electron microscopy and Fourier transform infrared spectroscopy. The BiOI thin film was made by painting a silica sol containing BiOI on GFC, which could be tailored to desired sizes to accommodate the TFFBR. The mass of BiOI on the GFC increased with the number of iterations of the painting process. SiO2 sol glued the BiOI particles tightly onto the GFC, making the thin film strong enough to resist fluid flushing in the TFFBR. The photocatalytic activity of the BiOI thin film was investigated by degrading bisphenol A (BPA) under simulated sunlight. Ninety eight percent of BPA (20 mg/L in 2 L) was degraded by the BiOI thin film sample of seven layers (GFC-7) on the TFFBR within 8 hr irradiation. The GFC-7 displayed good photocatalytic ability toward artificial sewage containing BPA in a wide pH range (5–9), and also demonstrated excellent durability and reusability. The working conditions were optimized and it was found that the thickness of the fluid film and residence time over the thin film were key factors affecting the photocatalytic efficiency.

High proportion of renewable energy was increased in the distribution network, which will face complex grid complex test and show the scale the diversity and complexity of the operating state. So that the evolution of Wind-photovoltaic-energy storage(Wind-PV-ES) hybrid network transient process is not clear. In the other hand, Transient simulation tool plays a significant role in obtaining a full and detailed response under various operation conditions. However, the simulation capability and speed become limited with increased system size. In order to study the background of high proportion of Wind-PV-ES in the distribution network, this paper model Wind-PV-ES and its control system in the multi-CPU cluster fine-grained real-time simulation platform. The control system was further decoupled according to its topology. The multi-CPU can be easily realized, and the computation loads are balanced by DG modeling. The model is used to calculate the load balancing as the optimal condition to be decoupled by the distribution parameters. Parallel computing to ensure the accuracy of the transient simulation results and convergence effect and improve the simulation speed. Then this paper used two typical examples to realize the verification of Multi-CPU simulation results. The simulation results show that the simulation accuracy decreases with the increase of model computation, but the simulation speed is greatly improved. The result reflects the characteristics and transient characteristics of grid -connected transient operation. The effectiveness of the proposed method is validated in integrated simulation of distributed generation system.

In order to improve the crushing soil effect of potato harvester, a vibration-type digging shovel with the amplitude and frequency adjustable was designed. The kinematic analysis of this vibration digging shovel was performed. A virtual prototyping model was established based on Solid Works and ADAMS software, and mechanical-hydraulic co-simulation was conducted in ADAMS. The virtual test results showed that: the amplitude of digging shovel was directly proportional to the system pressure; at constant system pressure, amplitude was inversely proportional to frequency; the maximum pressure value of the shovel on soil mass was lower than the breaking strength of potatoes.
