The investigation on the dynamics process of launch of ammunition under different conditions is important for improving its performance during design and contributes to adapt the complex variable modern battlefield for the ammunition. For the purpose of improving the firing accuracy and flight stability of an armour-piercing fin-stabilized discarding sabot, the sabot dynamic discarding behavior after the projectile being ejected from the muzzle at non-zero angles of attack and sideslip is simulated by coupling the computational fluid dynamics and the six degree of freedom exterior ballistic code through the unstructured dynamic mesh technique and user defined function. The flow field characteristics and the trajectory parameters of all sabots are obtained. In addition, the aerodynamic coefficients of projectile are also obtained. The numerical results show that the asymmetric flow field of the sabots can be observed under the influence of the asymmetric inflow. This will lead to the nonuniform distribution of pressure on the sabot surfaces. The different trajectories of three sabots appear due to the unsynchronized and asymmetrical discarding of sabot. The increased aerodynamic interference between projectile and sabot reduces the firing accuracy and flight stability of projectile. [ABSTRACT FROM AUTHOR]

Objective To investigate the safety and feasibility of laparoscopic wedge resection for gastric gastrointestinal stromal tumors (GIST). Methods One hundred GIST patients treated in our department between 2010 and 2014 were retrospectively enrolled, and their clinicopathological data were reviewed. Fifty patients underwent laparoscopic wedge resection, and open surgery cases were 1∶1 matched by tumor diameter. The clinicopathological characteristics, perioperative related factors, postoperative nutritional status and short-term outcome were compared between the two groups. Results Among the clinicopathological characteristics, only the age was of statistical significance (61.58±10.43 vs. 56.40±9.82, P=0.012). Over fifty percent of the tumors occurred in the gastric body. Although the short-term survival did not show statistical significance, the laparoscopic group showed predominant advantages in estimated blood loss [(48.60±48.89) ml vs. (137.60±140.69) ml, P<0.001], average hospital stay[ (12.14±4.32) d vs.(17.22±7.11) d, P<0.001], oral intake time[ (3.76±1.73)d vs. (6.28±3.73)d, P<0.01], decline of prealbumin [(0.07±0.04)g/L vs. (0.11±0.05)g/L, P<0.001)], decline of transferrin [(0.51±0.29)g/L vs. (0.64±0.30)g/L, P=0.034]and complication (2.0% vs. 14.0%, P=0.027). Conclusion Laparoscopic wedge resection is feasible and safe for GIST surgery, allows a rapid recovery and having a better nutritional status in patients, and is a less invasive approach for patients.

In order to evaluate the stability of mogroside V in gastrointestinal tract and study its in vitro metabolism, mogroside V was incubated with artificial gastric juice and human intestinal bacteria, and a liquid chromatography/mass spectrometry method by LCMS/IT-TOF was applied to analyze the products of mogroside V in artificial gastric juice and human intestinal bacteria culture medium. The results indicated that mogroside V was degraded quickly in artificial gastric juice to be secondary glycosides with two glycosyls or one glycosyl and mogrol without glycosyl. And the longer time it was incubated, the more completely it was degraded, its product was mogrol while the incubation time was 4 h. While in culture medium of human intestinal bacteria, mogroside V was transformed to mogroside IV(isomer)mogroside III(isomer), mogroside II(isomer)and mogroside I(isomer)by deglycosylation reaction, as well as to glycoside with six glycosyls,by glucosylation reaction. Therefore, a general knowledge on the degradation of mogroside V was obtained after this experiment, which would shed light on the further exploitation of mogroside V and Siraitia grosvenorii.

To investigate the influence of arbuscular mycorrhizal (AM) fungi inoculum on sugarcane in latosol acid soil, sugarcane plants were inoculated with AMF, and the soil property, the communities of original AMF and the plant growth were investigated. The results showed that AMF enhanced absorption of available potassium in soil, and increased the pH value. The communities of soil AMF were afected by AMF inoculants, and septate hypha and microsclerotia of dark septate endophytes (DSE) were found significantly more in the soil applied complex fertilizer than others whether applying AMF or not. AMF inoculation stimulated the plant growth, and increased the millable stalks and sugarcane productivity. [ABSTRACT FROM AUTHOR]

To explore new constituents in two‐dimensional materials and to combine their best in van der Waals heterostructures, are in great demand as being unique platform to discover new physical phenomena and to design novel functionalities in interface‐based devices. Herein, PbI2 crystals as thin as few‐layers are first synthesized, particularly through a facile low‐temperature solution approach with the crystals of large size, regular shape, different thicknesses and high‐yields. As a prototypical demonstration of flexible band engineering of PbI2‐based interfacial semiconductors, these PbI2 crystals are subsequently assembled with several transition metal dichalcogenide monolayers. The photoluminescence of MoS2 is strongly enhanced in MoS2/PbI2 stacks, while a dramatic photoluminescence quenching of WS2 and WSe2 is revealed in WS2/PbI2 and WSe2/PbI2 stacks. This is attributed to the effective heterojunction formation between PbI2 and these monolayers, but type I band alignment in MoS2/PbI2 stacks where fast‐transferred charge carriers accumulate in MoS2 with high emission efficiency, and type II in WS2/PbI2 and WSe2/PbI2 stacks with separated electrons and holes suitable for light harvesting. Our results demonstrate that MoS2, WS2, WSe2 monolayers with very similar electronic structures themselves, show completely distinct light‐matter interactions when interfacing with PbI2, providing unprecedent capabilities to engineer the device performance of two‐dimensional heterostructures. 1 图 1 异质结中 PbI2引起的MoS2发光增强与WSe2发光 淬灭 [ABSTRACT FROM AUTHOR]

The deviation of the warhead of a projectile from its axis can modify the aerodynamic force to increase the range and mobility of the projectile. The flow fields of a projectile, with deflection angles within 0°~8°, angles of attack from 0° to 8°, and Mach numbers from 2 to 5 were simulated numerically first. Compared with the experimental data, the numerical simulation is proved to be reliable. Then the flight characteristics of the deflected nose projectile were investigated with the calculated aerodynamic coefficients. The ballistic trajectories of the projectile with different deflection angles were obtained, and the principle of increasing range and its mobility were discussed. Results show that the deflected nose projectile is dynamically stable at high angle of attack. Its lift-to-drag ratio is far larger than that of normal projectile, leading to a longer range and a superior mobility. [ABSTRACT FROM AUTHOR]

In order to analyze the characteristics of transient dynamic response and the relationship between loads and vibration fundamental frequencies of the bolt in the role of damping,in considering the impact of anchoring medium of the bolt on dynamic and static damping and based on wave theory, the wave equation, which is about the elastic vibration of the bolt when suffered by transient excitation, was established. Analytical solution of displacement field of the bolt was solved under the boundary condition that it is fixed at the one end of the bolt and it is free at the other end of the bolt. The theoretical result shows there is a second order power function relationship between the fundamental frequency and load. In order to verify the theoretical result, the pullout test and nondestructive test of the indoor model bolts were used, through the spectrum analysis of the dynamic testing signals, the fundamental frequency was obtained under the corresponding load. Fitting function relationship between load and fundamental frequency by using the least squares also presents a second order power function relationship, the load and fundamental frequency are positively correlated when the load is less than the grip between the medium and bolt-rod, but it is the negative correlation between both when the load is more than the grip, and the results are consistent with the theoretical analysis.
