High performance aircraft are, by their very nature, often required to undergo manoeuvres involving high angles of attack. Under these conditions unsteady vortices emanating from the wing and the fuselage will impinge on the twin fins (required for directional stability) causing excessive buffet loads, in some circumstances, to be applied to the aircraft. These loads result in oscillatory stres...

Imomlbressibte Flow Summary.-The report presents the theoretical calculations of gust alleviation factor made for rigid aircraft and with one degree of freedom only (i.e., vertical motion). It is shown that for average gust lengths and for orthodox (tailed) aircraft the influence of thesecond degree of freedom (i.e., pitching) on the value of the gust alleviation factor is negligibly small, pro...

A microscopic mass balance approach has shown that the initial saturation (Is), absorption number (An), dose number (Do), and dissolution number (Dn) are four fundamental dimensionless parameters that can be used to estimate the fraction dose absorbed (~ of suspensions of poorly soluble drugs in humans. The dissolution number of a drug increases with decreasing its particle size. The effect of ...

In order to further help each unit that mitigates the poverty of impoverished regions improve efficiency alleviation, this paper establishes a alleviation performance evaluation index system. Firstly, we analyze correlation among indicators through matrix density diagram. Second, questions are divided into target layer (poverty performance), criterion efficiency, effect, and rate), indicator la...

Although silicon (Si) is the second most abundant element both on the surface of the Earth's crust and in soils, it has not yet been listed among the essential elements for higher plants. However, the beneficial role of Si in stimulating the growth and development of many plant species has been generally recognized. Silicon is known to effectively mitigate various abiotic stresses such as manga...
