A ceramic coating on 60vol.%SiCP/2009 aluminum matrix composite was prepared by plasma electrolytic oxidation (PEO) in silicate solution. The microstructure, composition and wettability of the PEO coating and its corrosion resistance were investigated. The generation mechanism of spark discharge on the SiC particles surface was also discussed. It is found that the insoluble compound (SiO2) from silicate solution is vital for the ignition of spark discharge on the SiC particles surface. The defects in the Al−Si−O compounds provide a priority path for the conduction of discharge current on the SiC particles surface. A uniform coating of 5.5 μm was fabricated after 1200 s. Moreover, with the increase of time, the surface free energy of PEO coating reached the maximum of 37.10 mJ/cm2at 40 s, and then decreased to 25.95 mJ/cm2at 1200 s. Furthermore, the corrosion resistance of the composite was greatly improved by PEO treatment.

Ileostomy diverts the flow of feces, which can result in malnutrition in the distal part of the intestine. The diversity of the gut microbiota consequently decreases, ultimately leading to intestinal dysbiosis and dysfunction. This condition can readily result in diversion colitis (DC). Potential treatment strategies include interventions targeting the gut microbiota. In this case study, we effectively treated a patient with severe DC by ileostomy and allogeneic fecal microbiota transplantation (FMT). A 69-year-old man presented with a perforated malignant tumor in the descending colon and an iliac abscess. He underwent laparoscopic radical sigmoid colon tumor resection and prophylactic ileostomy. Follow-up colonoscopy 3 months postoperatively revealed diffuse intestinal mucosal congestion and edema along with granular inflammatory follicular hyperplasia, leading to a diagnosis of severe DC. After two rounds of allogeneic FMT, both the intestinal mucosal bleeding and edema significantly improved, as did the diversity of the gut microbiota. The positive outcome of allogeneic FMT in this case highlights the potential advantages that this procedure can offer patients with DC. However, few studies have focused on allogeneic FMT, and more in-depth research is needed to gain a better understanding.

Quantification of currently attainable yield and fertilizer requirements can provide detailed information for assessing the food supply capacity and offer data support for agricultural decision-making. Datasets from a total of 5 408 field experiments were collected from 2000 to 2015 across the major wheat production regions in China to analyze the spatial distribution of wheat yield, the soil nutrient supply capacity (represented by relative yield, defined as the ratio of the yield under the omission of one of nitrogen (N), phosphorus (P) and potassium (K) to the yield under the full NPK fertilizer application), and N, P and K fertilizer requirements by combining the kriging interpolation method with the Nutrient Expert Decision Support System for Wheat. The results indicated that the average attainable yield was 6.4 t ha–1, with a coefficient of variation (CV) of 24.9% across all sites. The yields in North-central China (NCC) and the northern part of the Middle and Lower reaches of the Yangtze River (MLYR) were generally higher than 7 t ha–1, whereas the yields in Southwest China (SWC), Northeast China (NEC), and the eastern part of Northwest China (NWC) were usually less than 6 t ha–1. The precentage of area having a relative yield above 0.70, 0.85, and 0.85 for N, P, and K fertilizers accounted for 52.3, 74.7, and 95.9%, respectively. Variation existed in N, P, and K fertilizer requirements, with a CV of 24.8, 23.9, and 29.9%, respectively, across all sites. More fertilizer was needed in NCC and the northern part of the MLYR than in other regions. The average fertilizer requirement was 162, 72, and 57 kg ha–1for N, P2O5, and K2O fertilizers, respectively, across all sites. The incorporation of the spatial variation of attainable yield and fertilizer requirements into wheat production practices would benefit sustainable wheat production and environmental safety.

Regulated inter-mitochondrial fusion/fission is essential for maintaining optimal mitochondrial respiration and control of apoptosis and autophagy. In mammals, mitochondrial fusion is controlled by outer membrane GTPases MFN1 and MFN2 and by inner membrane (IM) GTPase OPA1. Disordered mitochondrial fusion/fission contributes to various pathologies, and MFN2 or OPA1 mutations underlie neurodegenerative diseases. Here, we show that the WBSCR16 protein is primarily associated with the outer face of the inner mitochondrial membrane and is important for mitochondrial fusion. We provide evidence of a WBSCR16/OPA1 physical interaction in the intact cell and of a WBSCR16 function as an OPA1-specific guanine nucleotide exchange factor (GEF). Homozygosity for a Wbscr16mutation causes early embryonic lethality, whereas neurons of mice heterozygous for the mutation have mitochondria with reduced membrane potential and increased susceptibility to fragmentation upon exposure to stress, suggesting roles for WBSCR16 deficits in neuronal pathologies.

Considering the complexity of reservoir systems, a model fusion approach is proposed in this paper. According to different inflow information represented, the historical monthly data can be constructed as two time series, namely, yearly-scale series and monthly-scale series. Even grey model (EGM) and adaptive neuro-fuzzy inference system (ANFIS) are adopted for the forecasts at the two scales, respectively. Grey relational analysis (GRA) is subsequently used as a scale-normalized model fusion tool to integrate the two scales' results. The proposed method is evaluated using the data of the Three Gorges reservoir ranging from January 2000 to December 2012. The forecast performances of the individual-scale models are improved substantially by the suggested method. For comparison, two peer models, back-propagation neural network and autoregressive integrated moving average model, are also involved. The results show that, having combined together the small-sample forecast ability of the EGM in the yearly-scale, the nonlinearity of the ANFIS in the monthly-scale, and the grey fusion capability of the GRA, the present approach is more accurate for holistic evaluation than those models in terms of mean absolute percentage error, normalized root-mean-square error, and correlation coefficient criteria, and also for peak inflow forecasting in accordance with peak percent threshold statistics.

Take water hydraulic slide valve core as the research object. Laser surface texturing (LST) technology was used to improve the valve core carrying capacity and hydrodynamic lubrication characteristics, which can process micro-texture on the surface of the core. And CFD method was taken to calculate flow field of smooth and laser surface texturing core respectively. For studying the influence of valve core micro-texture and valve core overlap lengths on hydrodynamic lubrication characteristic and carrying capacity of the core, core surface pressure distribution, surface pressure and friction force curves were drawn. Results show: The smooth valve core does not produce hydrodynamic lubrication effect, but textured valve core can bring the oil film load capacity, so as to make the effect of mixed friction between valve core and sleeve weaken. And along with the decrease of the core overlap length, the carrying capacity on the surface of the textured valve core does not decrease but increase when the valve core overlap length amount is greater than 2.5mm.The results provide important theoretical reference of studying and applying LST process technology to the valve core friction pair’s lubrication performance.

In the working process of hydraulic system, it is usually hard to match the operating parameters with the real-time load to get the optimized efficiency.

Results show that this method can improve the system efficiency by adjusting the input parameters to better match the output parameters on the premise of without changing the normal function of system. The study provides a theoretical basis for applying this method into practical engineering of hydraulic system efficiency optimization.

It provide an important basis for further monitoring of O-ring failure through contact strain changes in sealing groove.

In order to deeply research the structure discrepancy and modeling mechanism among different grey prediction models, the equivalence and unbiasedness of grey prediction models are analyzed and verified. The results show that all the grey prediction models that are strictly derived from x(0)(k) + az(1) (k) = b have the identical model structure and simulation precision. Moreover, the unbiased simulation for the homogeneous exponential sequence can be accomplished. However, the models derived from dx(1)/dt + ax(1) = b are only close to those derived from x(0) (k) + az(1)(k) = b provided that |a| has to satisfy |a| < 0.1; neither could the unbiased simulation for the homogeneous exponential sequence be achieved. The above conclusions are proved and verified through some theorems and examples. [ABSTRACT FROM AUTHOR]

The ethanol concentration, solid-to-solvent ratio, extraction temperature and extraction time were optimized by using orthogonal array design, an ultrasonic-assisted extraction (UAE) method was formed for extracting total flavonoids from Cassia Seeds. The optimal conditions for total flavonoids preparation were found to be extracted at 55 °C for 40 min with 75% (v/v) ethanol and a solid-to-liquid ratio of 1:30 (g/mL). The UAE was proven more efficient than the conventional extraction (CE) technique, which could be considered a time-saving method. Therefore, the UAE could be a promising candidate for extracting phenolic phytochemicals from natural plants.

The intake hood is the part which riveted in the external skin of the aircraft. During the flight of the aircraft, the engine casing is cooled down by the high-speed airflow which flows through the air intake duct. As the components suffer the impact of the high-speed airflow, the appearance of the intake hood must meet the requirements of the aerodynamic property. At the same time, its manufacturing quality has a certain impact on the aerodynamic performance of the aircraft, so its synthetic mechanical property is required high. The traditional air intake hoods are block-combination welded by the aluminum alloy sheet. Its complicated working procedure, long production cycle, high costs and the difficult weld methods make it difficult to guarantee the welding quality. In order to improve the useful life of the air intake hood, to lower the production difficulty and to solve the quality risks in the production due to the method of weld, in this article, the high-strength aluminum alloy ZL101A and plaster mould investment casting were used to mold the intake hood based on the three-dimensional geometric modeling of the air intake hood by software Pro/E, and then, the filling and solidification process of the air intake hood was simulated by the casting simulation software ProCAST to predict the defects such as misrun, cold shut, wrapped in air, the thermal centre and the residual stress and deformation which were displayed in the filling and the solidification processes of the metal. Then, the casting process of the air intake hood can be optimized to achieve a decrease or avoid casting defects in the actual production.
