Background Nonunion of femoral neck fractures following internal fixation presents a significant challenge, particularly in young patients. This study evaluated the efficacy valgus osteotomy treating fracture nonunion after failed adults. Methods A retrospective analysis was conducted including total 23 male patients with mean age 32.9 years, who underwent for nonunion. The procedure involved lateral closing wedge at subtrochanteric level, followed by dynamic hip screw (DHS). postoperative...
Soil salinization severely impacts plant cultivation. Lilium pumilum (L. pumilum) exhibits tolerance to saline–alkali stresses. One Bacillus cereus strain, LpBc-47, possesses the ability of growth promotion and tolerance. The microbial diversity L. was assessed through metagenomic sequencing. LpBC-47 obtained from subjected physiological biochemical analyses whole-genome effects endophytic bacteria on plants were evaluated by measuring parameters, indices, antioxidant enzyme activities, ROS...
Aim: The article explores celery-derived extracellular vesicles (CDEVs), characterized by high cellular uptake, low immunogenicity, and stability, as a therapeutic strategy for antitumor nanomedicines. Methods: methods employed in this study include vitro cell experiments such co-culture, Western Blot, flow cytometry. In vivo were conducted C57BL/6 tumor-bearing mice subcutaneously injected with Lewis lung carcinoma (LLC) cells. encompassed parameters survival rate, body weight, tumor size,...
Fine-resolution studies on the stem radius variation at short timescale can provide useful information about tree growth process and major environmental variables that trigger drive variation. This study investigated of Larix principis-rupprechtii Mayr growing in semi-humid Liupan Mountains Northwest China daily seasonal scales using high-resolution automatic band dendrometers from May to October 2015. The results showed has a clear diurnal pattern which be divided into contraction,...
Aeroengine mainshaft bearings are key components in modern aeroengines, and their main functions to support the rotation of shaft aeroengine harsh environments, such as high temperature, heavy load, speed oil break; reduce friction coefficient during high-speed shaft; reliably ensure accuracy power transmission aeroengine’s operation. The manufacture requires complex processes precise machining performance reliability, how intelligently complete production strength bearings, quickly...
Soil moisture plays a decisive role for tree growth and forest ecosystems services supply in dryland regions. Hence, it is necessary to clarify the spatio-temporal variation of soil under field conditions. This study selected hillslope Liupan Mountains covered by plantation Larix principis-rupprechtii Mayr (larch), main afforestation species north northwest China. The volumetric (VSM) root zone layers was monitored with time interval about 15 days during growing season (from May October)...
This paper presents a multi-variable sliding mode controller based on the model of flight environment and aerodynamics. The problem is for hypersonic missile to solve strong coupling, serious non-linear real-time in re-entry. We first build online estimate atmosphere density dynamic pressure. then use an aerodynamic calculate parameters by pressure slipstream angles. Next we design variable structure reduce its dependence structural parameters. Simultaneously, controller’s update could...
A self-compensating control strategy for harmonic parameters based on the crown porcupine optimization algorithm is proposed single-phase rectifier and two-phase inverter operation mode of bidirectional converter. In order to improve response speed voltage, instantaneous expressions phase angle coefficient amplitude dc-side voltage doubling fluctuation are derived, third calculated according Proportional Integral (PI) + Quasi-Proportional Resonance (QPR) double closed-loop method injected...
In order to study the influence of some parameters dual-zone electrostatic oil mist purifier on purification efficiency fine mist. Numerical models flow field, corona discharge, charge accumulation and particle motion were established. The results show that increases with increase acupuncture discharge electrode voltage decrease needle tip curvature radius. For PM2.5, particles in 0.3μm size range is lowest. Adjusting radius can enhance effect particles.
The water-carbon relationship in forests is complex and plays a crucial role the provision of important ecosystem services, such as water yield carbon storage. Understanding this intricate imperative for effectively managing multiple services forests. Therefore, study was conducted to investigate spatio-temporal variation storage well their larch plantations located semi-humid Liupan Mountains northwestern China. data during growing season were calculated using budget principle, which...
<title>Abstract</title> Background and Aims: Soil quality assessment is crucial for achieving sustainable soil management maintaining ecosystem health. However, there limited research on assessments in <italic>Rhododendron simsii</italic> forests. Methods In this study, we selected 17 physicochemical indicators as the total data set (TDS) utilised principal component analysis (PCA) to construct minimum (MDS). Linear/nonlinear scoring functions additive/weighted additive methods were employed...
Purpose This paper aims to study the influence of different seal structure parameters and working conditions on air-oil two-phase flow characteristics leakage cavity in bearing aero-engine spindle tester.

The regenerative cooling technique is widely used in the active thermal protection systems for airbreathing hypersonic engines due to its high energy utilization efficiency. However, design of channels complicated by presence several components inserted through combustor wall engine. With conventional method, bypassing channel would cause large pressure loss and nonuniform flow distribution. In this paper, an innovative topology optimization method proposed pylon. results show that with...
In order to solve the heat load problem of aviation piston air-cooled engine, this research takes an gasoline engine as object, tests cylinder pressure and temperature under calibrated power condition, establishes a one-dimensional simulation model, calculates inner outer boundary conditions cylinder, fluid-structure coupling model. The orthogonal test was established with four main structural parameters, fin thickness, spacing, length wall influencing factors. range analysis shows that...
This paper compared cultural and political factors in the cases of Ebola virus SARS-CoV-2 demonstrated that, since humans dominate world, their decisions have tremendous impacts on natural selection and, as society progresses, more evolutionarily successful viruses will emerge.
