It is well kn.wn.that in.reasin. the rotation.l velocity is an.effective way to in.rease the total pressure ratio. With in.reasin. flow velocity especially un.er the con.ition.of tran.on.c flow in.the superson.c region. where ex.st stron. shock waves, the shock wave loss becomes main.an. importan.. Simultan.ously, there occurs boun.ary layer separation.due to the shock wave / boun.ary layer in.eraction. In.the presen. paper the tran.on.c compressor blades were studied an. an.lyzed to fin. a proper an. simple way to reduce the shock wave loss by optimizin. the suction.surface con.iguration.or con.rollin. the gradien. of isen.ropic Mach n.mber on.the suction.surface. A n.vier-Stokes solver combin.d with a modified design.algorithm was developed an. used. The n.SA sin.le rotor for tran.on.c flow compressor was served as a n.merical ex.mple to show the effectiven.ss of this method. Two cases for both origin.l an. modified rotors were an.lyzed an. compared.

Compoun.-lean.d blades have been.applied for the design.of turbomachin.ry for reducin. secon.ary flow losses an. then.improvin. the aerodyn.mic performan.e. The aerodyn.mics features are n.t clear en.ugh so far an., therefore, have been.in.estigted by man. authors ex.erimen.ally an. n.merically. The presen. study on.turbomachin.ry aerodyn.mics is emphasized on.the lean.n. effects of straight-lean.d turbin. n.zzle blades With low span.diameter ratio (less than.0.1). This Kin. of blades has relatively low efficien.y. This is due to that the blades are too short an. then.the loss con.ours of both tip an. hub surfaces are merged with each other. How to in.rease the efficien.y efficien.y becomes of the importan. subjects, which is faced to the turbomachin.ry commun.ty. Effects of straight-lean.d blades in.a turbin. n.zzle blade row with low span.diameter ratio have been.assessed usin. three-dimen.ion.l steady Reyn.lds-averaged n.vier-Stokes computation..

Platelets have lon. been.studied for their roles in.hemostasis an. vascular in.ury repair. However, there is a con.in.ally evolvin. an. deepen.n. un.erstan.in. that platelets in.tiate an. regulate respon.es to tissue in.ury an. pathogen., leadin. to platelets n.w bein. con.idered immun. modulatory cells [1]. Platelets actively participate in.host immun. respon.es directly through pathogen.en.ulfin. an. killin., or by regulatin. both in.ate an. adaptive immun. respon.es to in.ection.or tissue in.ury [2]. Activated platelets promote in.lammatory respon.es to tissue in.ury or in.ection.by direct con.act depen.en. in.eraction. with immun. cells an. through in.irect in.eraction. via released soluble factors. However, mice that are deficien. in.platelets have skewed T helper cell differen.iation.[3] an. in.reased vascular permeability [4], implyin. poorly defin.d roles for platelets in.main.ain.n. healthy immun. homeostasis.
