1Electroacupuncture attenuates neuropathic pain after brachial plexus injury显示文摘Electroacupuncture has traditionally been used to treat pain, but its effect on pain following brachial plexus injury is still unknown. In this study, rat models of an avulsion injury to the left brachial plexus root(associated with upper-limb chronic neuropathic pain) were given electroacupuncture stimulation at bilateral Quchi(LI11), Hegu(LI04), Zusanli(ST36) and Yanglingquan(GB34). After electroacupuncture therapy, chronic neuropathic pain in the rats' upper limbs was significantly attenuated. Immunofluorescence staining showed that the expression of β-endorphins in the arcuate nucleus was significantly increased after therapy. Thus, experimental findings indicate that electroacupuncture can attenuate neuropathic pain after brachial plexus injury through upregulating β-endorphin expression.Shenyu Zhang Hailiang Tang Junming Zhou Yudong Gu 2014Neural Regeneration Research2014,9,14:7
2Enhanced Dielectric Response in Mg-doped CaCu_3Ti_4O_(12) Ceramics显示文摘CaCu3Ti4O12 ceramics substituted by Mg for Ca were prepared by the solid state reaction method. The crystal structures, microstructures, and dielectric properties of the Ca1-xMgxCu3Ti4O12 ceramics were investigated. At lower doping concentrations, the substitution of Mg for Ca caused a decreased lattice constant, while at higher doping concentrations, some of the Mg dopants started to replace Ti and resulted in an increased lattice constant, and some could also replace Cu due to the similar ion radius between Mg and Cu ions. Mg doping was found to promote the grain growth of Ca1-xMgxCu3Ti4O12 ceramics during sintering. Grain boundary resistance of the Ca1-xMgxCu3Ti4O12 ceramics was found to be increased by Mg doping. Enhanced dielectric properties was observed in the Ca1-xMgxCu3Ti4O12 ceramics with x=0.05 for the frequency range from 1 kHz to 20 kHz. For other doping concentrations, the dielectric losses of Ca1-xMgxCu3Ti4O12 ceramics were generally lowered.Wang Li Shenyu Qiu Nan Chen Guoping Du 2010Journal of Materials Science & Technology2010,26,8:6
3Effect of Nonequilibrium Condensation of Moist Air on the Boundary Layer in a Supersonic Nozzle显示文摘When condensation occurs in supersonic flow fields, the flow is thected by the latent heat released. In the present study, Navier-Stokes equations were solved numerically using a 3rd-order MUSCL type TVD finitedifference scheme with a second-order fractionabetep for time integration. Baldwin-Lomax model, that is the algebraic model, called the zero equation model was used in the computations. The effects of initial conditions (initial degree of supersaturation and total temperature in the reservoir) on condensing fiow of moist air in a supersonic circular half nozzle were investigated. In this case, the effect of condensation on the boundary layer was also discussed in detail. As a result, the simulated flow fields were compared with experimental data in good agreement, and the velocity and temperature profiles were largely changed by condensation.ShigeruMatsuo ShenYu 1997Journal of Thermal Science1997,6,4:6
4Construction of piezoelectric BaTiO_(3)/MoS_(2) heterojunction for boosting piezo-activation of peroxymonosulfate显示文摘The rapid recombination of charge carriers in piezoelectric materials has always been the problem that limits their piezoelectric performance for removal of organic pollutants in water.Herein,we construct a piezoelectric Ba TiO_(3)/MoS_(2)(BTO/MS)that follows a type II heterojunction charge transfer system to inhibit the recombination of electron-hole(e^(-)-h^(+))pairs,which is beneficial to the activation of peroxymonosulfate(PMS)for the removal of antibiotic ornidazole(ORZ)pollutants.The optimal ratio of BTO/MS for ORZ degradation under the piezo/PMS process is 13.9,3.6,62.1 and 2.0 times higher than that of the BTO/piezo,MS/piezo,(BTO/MS)/PMS and(BTO/MS)/piezo processes,respectively.The high efficiency charge separation in the piezoelectric heterojunction of BTO/MS promotes the activation of PMS,resulting in the synergy of pizeocatalysis and PMS oxidation during the process of ORZ degradation.This study provides an idea for enhancing piezo-activation of PMS by constructing heterojunctions in piezoelectric materials.Yanxi Chen Shenyu Lan Mingshan Zhu 2021Chinese Chemical Letters2021,32,6:5
5Effect of Different Dietary Protein and Lipid Levels on the Growth,Body Composition,and Intestinal Digestive Enzyme Activities of Juvenile Yellow Drum Nibea albiflora(Richardson)显示文摘An 8-week feeding trial was conducted to determine the optimal dietary protein-to-lipid ratio for juvenile Nibea albiflora with an initial weight of(11.76 ± 0.20) g.Nine experimental diets containing different concentrations of protein(40%,47%,or 54%) and lipids(5%,9%,or 13%) in a 3 × 3 factorial experimental design were tested in triplicate groups of fish,while the protein-to-energy(P/E) ratios of the diets varied in the range of 19.74–28.32 mg k J^(-1).Results showed that fish fed diets containing 9% or 13% lipids with 54% protein exhibited significantly higher weight gains and specific growth rates than those fed other diets.The feed conversion rate of fish fed the diet with 40% protein and 5% lipids was significantly poorer than that of fish fed other diets.The protein efficiency rate of fish fed diets with 5% lipids was significantly lower than that of fish fed 9% or 13% lipid diets.Carcass lipid and energy contents were positively correlated with dietary lipid level regardless of protein level.Fish fed a 54% protein diet showed the highest trypsin activity.The intestinal lipase activity of fish fed the diet containing 13% lipids was significantly higher than that of fish fed 5% or 9% lipid diets.These results demonstrate the high protein dietary requirements of N.albiflora.A diet containing 54% protein and 9%–13% lipids with a P/E ratio of 26.2–27.81 mg protein k J^(-1) can be considered optimal for juvenile N.albiflora.WANG Ligai HU Shenyu LOU Bao CHEN Dongxing ZHAN Wei CHEN Ruiyi LIU Feng XU Dongdong 2018Journal of Ocean University of China2018,17,5:4
6ABOUT THE BASIC INTEGRAL VARIANTS OF HOLONOMIC NONCONSERVATIVE DYNAMICAL SYSTEMS显示文摘In this paper,we prove that for holonomic nonconservative dynamical system the Poincareand Poincaré-Cartan integral invariants do not exist.Instead of them,we introduce the integral variants ofPoincaré Cartan’s type and of Poincaré’s type for holonomie noneonservative dynamical systems,and usethese variants to solve the problem of nonlinear vibration.We also prove that the integral invariants intro-duced in references[1]and[2]are merely the basic integral variants given by this paper.Liu Duan Luo Yong (Beijing Institute of Technology)Xin Shenyu (P.O.Box 22,Datong,Shanxi) 1991Acta Mechanica Sinica1991,7,2:3
7Investigation of ion-atom collision dynamics through imaging techniques显示文摘The principle and technique details of recoil ion momentum imaging are discussed and summarized. The recoil ion momentum spectroscopy built at the Institute of Modern Physics (Lanzhou) is presented. The first results obtained at the setup are analyzed. For 30 keV He2+ on He collision, it is found that the capture of single electron occurs dominantly into the first excited states, and the related scattering angle results show that the ground state capture occurs at large impact parameters, while the capture into excited states occurs at small impact parameters. The results manifest the collision dynamics for the sub-femto-second process can be studied through the techniques uniquely. Finally, the future possibilities of applications of the recoil ion momentum spectroscopy in other fields are outlined.MA XinWen ZHU XiaoLong LIU HuiPing LI Bin ZHANG ShaoFeng CAO ShiPing FENG WenTian XU ShenYue 2008Science China(Physics,Mechanics & Astronomy)2008,51,7:2

9Simulation and Prediction of Soil Organic Carbon Dynamics in Jiangsu Province Based on Model and GIS Techniques显示文摘Based on the databases of soils, meteorology, crop production, and agricultural management, changes in the soil organic carbon (SOC) of agro ecosystems in Jiangsu Province were simulated by using a soil organic carbon model with a linkage of GIS. Four data sets of soil organic carbon measured from various field experiments in Jiangsu Province were used to validate the model. It was demonstrated that the model simulation in general agreed with the field measurements. Model simulation indicated that the SOC content in approximately 77% of the agricultural soils in Jiangsu Province has increased since the Second National Soil Survey completed in the early 1980s. Compared with the values in 1985, the SOC content in 2000 was estimated to increase by 1.03.0 g kg 1 for the north and the coastal areas of the province, and by 3.55.0 g kg 1 for the region of Tai Lake in the south. A slight decrease (about 0.51.5 g kg 1 ) was estimated for the central region of Jiangsu Province and the Nanjing Zhenjiang hilly area. Model prediction for 2010 A.D. under two scena rios, i.e., with 30 and 50% of the harvested crop straw incorporation, suggested that the SOC in Jiangsu Province would increase, and thus that the agricultural soils would have potential as organic carbon storage. The incorporation of crop straw into soils is of great benefit to increase soil carbon storage, consequently to benefit the control of the rise of atmospheric CO 2 concentration and to maintain the sustainable development of agriculture.SHENYu HUANGYao ZONGLiang-gang ZHANGWen XUMao LIULin-wang 2003Agricultural Sciences in China2003,2,9:2
10PGE2/EP4 skeleton interoception activity reduces vertebral endplate porosity and spinal pain with low-dose celecoxib显示文摘Skeletal interoception regulates bone homeostasis through the prostaglandin E2(PGE2)concentration in bone.Vertebral endplates undergo ossification and become highly porous during intervertebral disc degeneration and aging.We found that the PGE2 concentration was elevated in porous endplates to generate spinal pain.Importantly,treatment with a high-dose cyclooxygenase 2 inhibitor(celecoxib,80 mg·kg−1 per day)decreased the prostaglandin E2 concentration and attenuated spinal pain in mice with lumbar spine instability.However,this treatment impaired bone formation in porous endplates,and spinal pain recurred after discontinuing the treatment.Interestingly,low-dose celecoxib(20 mg·kg−1 per day,which is equivalent to one-quarter of the clinical maximum dosage)induced a latent inhibition of spinal pain at 3 weeks post-treatment,which persisted even after discontinuing treatment.Furthermore,when the prostaglandin E2 concentration was maintained at the physiological level with low-dose celecoxib,endplate porosity was reduced significantly,which was associated with decreased sensory nerve innervation and spinal pain.These findings suggest that low-dose celecoxib may help to maintain skeletal interoception and decrease vertebral endplate porosity,thereby reducing sensory innervation and spinal pain in mice.Peng Xue Shenyu Wang Xiao Lyu Mei Wan Xialin Li Lei Ma Neil CFord Yukun Li Yun Guan Wenyuan Ding Xu Cao 2021Bone Research2021,9,3:2
11Passive Control of Transonic Flow Fields with Shock Wave Using Non-equilibrium Condensation and Porous Wall显示文摘When non-equilibrium condensation occurs in a supersonic flow field.the flow is affected by the latent heat released.In the present study.in order to control the transonic flow field with shock wave,a condensing flow was produced by an expansion of moist air on a circular bump model and shock waves were occurred in the supersonic parts of the fields.Furthermore,the additional passive technique of shock /boundary layer interaction using the porous wall with a cavity underneath was adopted in this flow .The effects of these methods on the shock wave characteristics were investigated numerically and experimentally.The result obtained showed that the total pressure loss in the flow fields might be effectively reduced by the suitable combination between non-equilibrium condensation and the position of porous wall.MasanoriTanaka Shigerumatsuo ToshiakiSetoguchi Kenjikaneko Heuy-DongKim ShenYu 2003Journal of Thermal Science2003,12,2:1

15Near-infrared response Pt-tipped Au nanorods/g-C_(3)N_(4) realizes photolysis of water to produce hydrogen显示文摘The search for a suitable cocatalyst for graphitic carbon nitride(g-C_(3)N_(4)) to realize efficient photocatalytic hydrogen(H_(2)) evolution has been regarded as one of the most valid tactics to alleviate energy crisis.Herein,a ternary Pt-tipped Au nanorods(Pt-Au)/g-C_(3)N_(4) heterostructure is constructed,which shows excellent H_(2) production performance in visible and near-infrared(NIR) region,especially in NIR region with a rate of 51.6 μmol g^(-1)h^(-1).Therein,not only is the optical absorption ability of g-C_(3)N_(4) broadened,the light absorption range is also extended to NIR region through introduction of Pt-Au architectures.Besides,analysis of the hot electrons generated in energy relaxation of plasmon indicates hot electron transfers fromexcited Au nanorods to Pt nanoparticles,resulting in H_(2) evolution.Compared with bare g-C_(3)N_(4),the superior photocatalytic activity could be attributed to the surface plasmon resonance effect(SPR) of Au nanorods and the electron-sink function of Pt nanoparticles.This work provides an insight into the improvement of photocatalytic performance via combination of NIR-responsive plasmon metal with photocatalysts.Yang Guo Qixin Zhou Xiaolin Chen Yunzhi Fu Shenyu Lan Mingshan Zhu Yukou Du 2022Journal of Materials Science & Technology2022,,24:1

17Sequence Stratigraphy and Tectonic Environment of the Chartai Group,Inner Mongolia显示文摘The Middle Proterozoic Chartai Group separated by two unconformities consists of three depositional se-quences: the Shujigou Formation-Zenglongchang Formation (DS Ⅰ), the Agulugou Formation (DS Ⅱ), andthe Liuhongwan Formation (DS Ⅲ). The carbonate platform and back-platform basin are the basic environ-ment model of the Chartai Group. The syndepositional faults on the oceanward side of the carbonate platformand large-scale slumping in the soft sediments are important marks of facies tracts. The newly establishedZenglongchan uplifting, an epeirogenetic uplifting, plays an important role in the formation of thepalaeogeographic framework of the Chartai Group. The stratigraphic correlation between the Chartai Groupand the Bayan Obo Group is made for the first time by using sequence stratigraphic principle and model estab-lished by P.R. Vail. The Chartai Group, which was deposited on the northern passive continental margin of theNorth China platfom, represents the platform cover.Qiao Xiufu Yao Peiyi Wang Chengshu Tan Lin Zhu Shenyu Zhou Shengde Zhang Yuqing Institute of Geology,Chinese Academy of Geological Sciences, Beijing Regional Geological Survey Party,Geological Bureau of Inner Mongolia,Hohhot Sun Sheping 1991Acta Geologica Sinica(English Edition)1991,65,3:1
18Passive Control of Steady Condensation Shock Wave显示文摘When condensation occurs in supersonic flow fields, the flow is affected by the latent heat released, and if the heat released exceeds a certain quantity, a condensation shock wave will occur There are many papers for the passive control of shock-boundary layer interaction using the porous wall with a plenum underneath on the application of the technique to transonic airfoil flows. In the present study, this passive technique is applied to the control of a steady condensation shock wave generated in a supersonic nozzle. In order to clarify the effect of the passive shockboundary layer control on condensation shock, Navier-Stokes equations were solved numerically using a 3rd-order MUSCL type TVD finite-difference scheme with a second-order fractional-step for time integration. As a result, the simulated flow fields were compared with experimental data in good agreement and the aspect of the flow field has been clarified.ShigeruMatsuo ShenYu2000Journal of Thermal Science2000,9,4:1
19Effect of Nonequilibrium Homogenous Condensation on Flow Fields in a Supersonic Nozzle显示文摘When condensation occurs in a supersonic flow field, the flow is affected by the latent heat released. In the present study, a condensing flow was produced by an expansion of moist air in a supersonic circular nozzle, and, by inserting a wedge-type shock generator placed in the supersonic part of the nozzle, the experimental investigations were carried out to clarify the effect of condensation on the normal shock wave and the boundary layer. As a result, the position of the shock wave relative to the condensation zone was discussed, together with the effect of condensation on pressure fiuctuations. Furthermore, a compressible viscous two-phase flow of moist air in a supersonic half nozzle was calculated to investigate the effect of condensation on boundary layer.ToshiakiSetoguchi ShenYu1997Journal of Thermal Science1997,6,2:1
20Effects and Mechanisms of Oil Cakes on the Growth of Cucumber (Cucumis sativus L.) Under Continuous Cropping System显示文摘Fxperiments on the effect of soil amendment with rape (Brassica chinensis L.) seed cake, cotton (Gossypium hirsutum L.) seed or sesame (Sesamum indicum L.) seed cake on the growth of cucumber seedlings under a continuous cropping system were conducted in a greenhouse environment. The results indicated that two applications of sesame seed cake (0.1 and 0.5 %, w/w) increased the growth of cucumber, but the rape oil cake showed a negative effect at a rate of 1.5% (w/w). The sesame seed cake was separated into four fractions (Ⅰ, Ⅱ, Ⅲ and Ⅳ) according to the polarity, and all four fractions had a positive effect on the growth of cucumbers under a continuous cropping system. Fraction number Ⅲ was isolated into 25 proportions by silicon column, and only oleic acid, palmitic acid and octadecanoic acid were identified in proportion 10 by GC-MS in which 93.3% was oleic acid and palmitic acid. The oleic acid had a significant and positive effect on cucumber growth under salt stress at the level 30 mmol and showed slight resistance to several pathogenic fungi.RUANWei-bin LIUMo-han PANJie WangJing LUWen-long MACheng-cang WANGJing-guo SHENYue GAOYu-bao 2003Agricultural Sciences in China2003,2,10:1
