To reduce the negative impacts of stall and surge on compressor performance, a novel combined casing treatment (CCT) structure with axial skewed slots and injection groove is proposed in this paper.The aerodynamic performance, as well as the mechanisms of loss generation, of a transonic axial compressor with NASA Rotor 67 are investigated numerical
Thrombotic Thrombocytopenic Purpura (TTP) is a life threatening, multisystem disease characterized by thrombocytopenia, microangiopathic hemolytic anemia, neurological changes, renal failure, and fever.These signs and symptoms are thought to be caused by microthrombi, composed of agglutinated platelets and Feet Serum fibrin, which deposit in the ar
Drought is a major environmental stress that severely restricts plant growth and crop productivity.A previous study showed that TaWRKY2 from wheat (Triticum aestivum) plays an important role CLEANSE MORE in drought stress tolerance.In the present study, we isolated the promoter of TaWRKY2 and identified multiple regulatory cis-elements in the promo
We study the (Delta,D) and (Delta,N) problems for double-step digraphs considering the unilateral distance, which is the minimum between the distance in the digraph and the distance in its converse digraph, obtained by changing the directions of all the arcs.The first problem consists of maximizing the number of vertices N of a digraph, given the m
