NiSnO3 nanoparticles were synthesized via a facile hydrothermal technique as an anode material for lithium ion batteries (LIBs), The good reversible ability of NiSnO3 electrode is mainly attributed to the NiO, Sn and Li2O formed in the first discharge of the NiSnO3 electrode can act as buffer substrates for each other, which buffer the volume change of the NisnO3 electrode during the charge and discharge reaction. The diffusion coefficient of lithium ions in the process of charging and discharging of NiSnO3 nanomaterials was obtained by galvanostatic intermittent titration technique (GITT). It can be seen that NiSnO3 nanomaterials have a faster charging and discharging rate, which is mainly attributed to the higher specific surface area (94.40 m²/g) of NiSnO3 nanoparticles. At the same time, the smaller nanoparticle size (4-9 nm) helps to improve the contact area between the surface of the NiSnO3 electrode and the electrolyte, reducing the diffusion distance of lithium ions. Further exploration of the adsorption energy (-2.93 eV), electron density difference, intrinsic charge transfer (1.01 e), diffusion barrier (0.112 eV) and diffusion coefficient (1.73×10-4 cm²/s) of lithium ions on NiSnO3 surface were conducted using first principles. The results all indicate that there is a strong interaction between lithium ions and NiSnO3 surface, and a fast charging and discharging rate of NiSnO3 nanomaterials. This article demonstrates that NiSnO3 has the potential to serve as a promising anode material for LIBs from both experimental and theoretical perspectives. [ABSTRACT FROM AUTHOR]

The self 一 management of patients with multiple chronic conditions has more complex characteristics and needs than those of single chronic diseases and plays a central role in healthy disease regression. This paper focuses on the characteristics, current status, barriers and challenges of self 一 management in patients with multiple chronic conditions, and suggests that self 一 management of multiple chronic conditions should be viewed from a dynamic and developmental perspective. When providing self - management support to patients, it should be based on their complex self 一 management needs, identifying specific barriers to the self - management process, establishing self 一 management links between multiple chronic conditions, and developing personalised self - management support content and methods based on patients' preferences, goals, and available resources, to improve their self 一 management abilities and health outcomes.

Objective To study the regulation effects of Bazhen Decoction combined with Baizhu Fuzi Decoction on glucose metabolism and estrogen level in rats with polycystic ovary syndrome. Methods The rat model of polycystic ovary syndrome was established by subcutaneous injection of human chorionic gonadotropin (HCG) combined with insulin. Rats were randomly divided into the polycystic ovary syndrome group, the Baizhu Fuzi Tang group (6.4 g/kg), the Bazhen Tang group (9.2 g/kg), the Bazhen Tang combined with Baizhu Fuzi Tang group (11.55 g/kg) and the diethylstilbestrol group (0.5 mg/kg). A blank control group (unmodulated rats) was set up with 10 rats in each group. The uterine index of rats was determined and calculated. Fasting blood glucose (FBG), 2 h postprandish blood glucose (2 h PBG) and fasting insulin (FINS) were determined and insulin sensitivity index (ISI) and insulin resistance index (IR) were calculated. Serum estradiol (E2), testosterone (T), luteinizing hormone (LH), follicle stimulating hormone (FSH), prolactin (PRL), anti-Mullerian tube hormone (AMH) and insulin-like growth factor 1 (IGF-1), C-reactive protein (CRP), interleukin (IL) -6, tumor necrosis factor (TNF) - α, total peroxidase activity (T-AOC), superoxide dismutase (SOD) and malondialdehyde (MDA) levels in ovarian tissue were detected by enzyme-linked immunosorbent assay (ELISA). The pathological changes of ovarian tissue were detected by hematoxylin-eosin (HE) staining. Real-time quantitative polymerase chain reaction (qPCR) was used to determine mRNA levels of ARA70, CBP, SCR1 and HOXA10 in endometrium and mRNA expressions of AMPK, GLUT4 and PPARγ in ovarian tissue. Western blot assay was used to determine expression levels of AMPK, GLUT4 and PPARγ in ovarian tissue. Results Compared with the polycystic ovary syndrome group, uterine index, FINS, FBG, 2 h PBG, IR levels, serum T, LH, FSH, PRL, AMH, IGF-1 levels, ovarian tissue CRP, IL-6, TNF- α, T-AOC and MDA level, endometrial ARA70, CBP, SCR1 mRNA level of rats decreased significantly in the Baizhu Fuzi decoction group, the Bazhen decoction group and the Bazhen decoction combined with Baizhu Fuzi decoction group (P＜0.05). ISI level, serum E2 level, ovarian tissue SOD level, endometrial HOXA10 mRNA level, ovarian tissue AMPK, GLUT4 and PPARγ mRNA and protein levels were significantly increased (P＜0.05). The above indexes were significantly changed in the Bazhen decoction and Bazhu Fuzi decoction group than those of the Bazhu Fuzi decoction group and the Bazhen decoction group (P＜0.05). Conclusion Bazhen Decoction combined with Baizhu Fuzi Decoction can regulate glucose metabolism, inhibit ovarian tissue oxidation and inflammatory damage, improve endometrium tolerance, regulate estrogen level, and improve the progression of polycystic ovary syndrome in rats. The mechanism may be related to the regulation of AMPK/GLUT4/PPARγ pathway. [ABSTRACT FROM AUTHOR]

The guidance and control semi physical simulation system plays an important role in the development of guided weapons, and is an important way to verify the correctness of missile guidance and control system design and software design. The traditional Windows operating system has poor real-time performance, which brings many uncertainties to the hardware in the loop simulation test. Therefore, this paper uses the Windows+RTX scheme to complete the hardware and software design of the hardware in the loop simulation system. Through shared memory, the communication between Windows processes and RTX processes is realized to ensure the accuracy of data transmission and the real-time performance of the system. The final missile guidance and control semi physical simulation test results show that the designed semi physical simulation system is reasonable, and has good real-time performance, high reliability, and strong universality.

Two n-butanol zirconium crosslinkers were prepared using n-butanol zirconium as the central ionic reagent and 3-amino-1, 2-propanediol (APG) and N-methyldiethanolamine (MDEA) as the organic ligands, respectively. A series of water-based fracturing fluids were prepared with konjac glucomannan (KGM) solution and n-butanol zirconium crosslinker The morphology, structure and properties of fracturing fluid are systematically characterized by Fourier transform infrared spectrometry (FT-IR), nuclear magnetic resonance spectroscopy (NMR), high resolution mass spectrometer (HRMS), rheometer, scanning electron microscopy (SEM), and differential scanning calorimeter (DSC) . The reaction pathway of zirconate and KGM crosslinking is discussed. The sol-gel transition point is accurately determined by Winter-Chambon formula. The effects of reactant concentration and ligand species on storage modulus (G'), loss modulus (G″), and solgel transition time (tcr) are studied. It is found that compared with APG ligand, the organozirconium/KGM gel system with MDEA as ligand have better delayed cross-linking performance, better temperature and shear resistance. Its tcr shows a trend of first decreasing and then increasing with the increase of KGM concentration, and a decreasing trend with the increase of ligand concentration and crosslinking agent concentration. When the concentration of KGM solution is controlled at 4. 0 g/L, the delay time of gel system can be adjusted within 7~45 min at room temperature, the sol-gel transition temperature (Tsol-gel) is 71. 4 ℃, and its temperature resistance can reach 120 ℃. The viscosity of 171 mPa·s is maintained at a shear rate of 170 s-1 . The organic zirconium crosslinked KGM gel system provides a useful reference for the research and application in the field of petroleum exploitation. [ABSTRACT FROM AUTHOR]

China has the third largest coal reserves and the first coal consumption in the world. China's coal resource areas are highly coincident with major grain producing areas or ecologically fragile areas. Under high-intensity mining, overburden strata move violently and surface damage is serious. The large-scale exploitation of underground coal resources will inevitably cause the destruction of surface attachments such as cultivated land, and disturbance of ecological environment in mining area, which will seriously affect the sustainable development of mining area. The surface damage induced by high-intensity mining includes static damage and dynamic damage, but the dynamic damage is more serious. Surface subsidence velocity can reflect the severity of surface movement and deformation. So, in this paper, we chose subsidence velocity as the dynamic deformation index to reveal the dynamic development law of surface damage induced by high-intensity mining in mining area. First, we took the field observed data of ground movement observation station set on the side of terminal line of 2407 working area as an example, and selected several periods of data in the full mining stage as samples. Through the analysis of mathematical statistics, we concluded that the subsidence velocity curve has the distribution characteristics of right skewness. Second, we established a physical similarity model test according to the mining and geological conditions of 2407 working area. Combined with this experiment, we found that the average of bedrock break angle was 56°, which revealed the formation mechanism of stepped crack. Under high-intensity mining, the bedrock was full-thickness fractured along the break angle of bedrock, the main failure type of loose layer was shear failure and the direction of failure was upward in the vertical direction. When the failure reached the surface, the stepped crack appeared on the ground surface. According to the analysis of the measured data of 2407 working area, it was found that overlying strata and surface had the periodic failure characteristics along the advancing direction of working area under high-intensity mining, the period of roof caving was the same as that of stepped crack, and the maximum subsidence velocity was located at stepped crack. The position of maximum subsidence velocity can be determined by the break angle of bedrock in real time. Then, we selected the lognormal density function with right skewness and normality, and combined with the real-time location distribution characteristics of maximum surface subsidence velocity to construct the dynamic prediction model of subsidence velocity. The reliability of the dynamic prediction model was analyzed by selecting the field measured data of subsidence velocity from adjacent high-intensity mining working face of Bulian Tower coal mine. The results showed that the correlation coefficient between predicted data and measured data was over 0.9, and the ratio of standard deviation to measured maximum subsidence velocity was less than7.0%. It showed the high reliability of the model. This research can provide guidance for dynamic prediction of mining subsidence in similar mining conditions. [ABSTRACT FROM AUTHOR]
