licorice, the oldest chinese traditional medicine, is widely used in the treatment of human diseases. due to the deficiency of wild resource, selecting and breeding becomes a key issue to expanding the supply of licorice. spaceflight technology will become a new method for medicinal plants. the aim of this study was to investigate the effect of spaceflight on the components and anti-inflammator...

An implicit unsteady upwind solver including a mesh motion approach was applied to simulate a helicopter including body, main rotor and tail rotor in hover flight. The discretization was based on a second order finite volume approach with fluxes given by the Roeand#39;s scheme. Discretization of Geometric Conservation Laws (GCL) was devised in such a way that the three-dimensional flows on arbi...

martin powell makes the point that the death of the national health service (nhs) is constantly asserted without criteria. this article suggests that the nhs is many things, which makes criteria unstable. the alignment of interests in the structure of the nhs enables both overheated rhetoric and political strength, and that pluralization of provision might actually undermine that alignment over...

A method is presented for the stress analysis of flight vehicles under different flight conditions including gust and control surface deflection (or maneuver) using the governing equations of rigid-body motions and elastic deformations. The Lagrangian approach is used to derive the governing equations of motions. For this purpose, the basic equations of motions are derived in terms of potential...

time-of-flight diffraction method (tofd) is an amplitude-independent sizing method which is based on the measurement of time-of-flight of defect tip diffracted waves. although tofd can measure through-wall length of defect accurately, this method is not capable of measuring horizontal defect size. in this paper, a new tofd method for evaluating horizontal planar defects is presented. the finite...

every digital transmission system requires frame alignment. it is necessary to identify the varius signal componets and to bring receiver into phase with respect to the transmission format so that the digits can be properly assembled for demultiplexing. fast and reliable frame alignmant is important, and therefore has been a subject for study. this paper a comprehensive analysis of frame alignm...

Unmanned aerial vehicles (UAVs) have been used for increasing research applications in atmospheric measurements. However, most current solutions these are based on a single UAV with limited payload capacity. In order to address the limitations of UAV-based approach, this paper proposes new concept measurements using tandem flying multicopters as distributed sensor platform. Key challenges propo...
