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...

For many conservationists, butterflies are some of the key species that can indicate the quality of an environment not only for themselves but for many other, often less visible, species. Some of their specific needs are often well known, but movements around their habitat and important factors within it are less understood. To help address this issue, a new study reports for the first time the...

Many passerines migrate during the night and at high altitudes, making their migration difficult to observe. By using tracking radars we have been able to make exact observations of the flight behaviour of passerines on nocturnal migration, which has enabled us to test several hypotheses about adaptive values and constraints regarding migratory behaviour in different ecological contexts. We hav...

Despite mass movements of insects being documented for decades, whether dragonflies migrate in Europe has not yet been experimentally tested. Similarly, little is known about the influence weather on movement decisions and intensity dragonflies. Taking advantage large along Baltic Sea coast Latvia, we investigated European showed directed indicative migratory behaviour how influences their move...

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...

this study extends prior researches by exploring the effect of organizational orientations on export performance. building on the already extensive literature, we developed a model of relationship. a total of 120 usable questionnaires were received from the iranian food industry smes. the results indicated that entrepreneurial orientation, market orientation and learning orientation positively ...

Trajectory orientation is a procedural concept that enables en route controllers to plan and coordinate trajectories across sector boundaries while efficiently maintaining separation and conforming to flow-rate constraints. Today’s sector-oriented procedures are characterized by an emphasis on controller actions to protect their sector’s internal airspace. In contrast, a trajectory orientation ...
