t.is paper examines t.e t.ansport.analysis, including bot. heat.t.ansfer and mass t.ansfer, in hybrid nanofluid flow cont.ining gyrot.ct.c microorganisms t.wards a curved oscillat.ry surface. t.e influence of magnet.c fields is also inspect.d in t.rms of t.eir physical charact.rist.cs. t. depict.t.e phenomena of t.ansport. modified versions of bot. Fick's and Fourier's laws are used. Addit.onally, t.e charact.rist.cs of bot. het.rogeneous and homogeneous chemical react.ons are also incorporat.d. Ut.lizing a curvilinear coordinat. syst.m, t.e flow problem is formulat.d as part.al different.al equat.ons(PDEs)for moment.m, concent.at.on, microorganism field, and energy. An analyt.cal solut.on t. t.e obt.ined flow equat.ons is achieved ut.lizing t.e homot.py analysis met.od(HAm).t.e effect. of significant.flow paramet.rs on t.e pressure and microorganism fields, velocit., oscillat.on velocit., concent.at.on, and t.mperat.re dist.ibut.ons are shown via graphs. Furt.ermore, t.e variat.ons in skin frict.on, mass t.ansfer rat., heat.t.ansfer rat., and local mot.le number due t. different.involved paramet.rs are present.d in t.bles and are analyzed in det.il. Graphical result. indicat. t.at.t.e curves of velocit. and t.mperat.re fields are enhanced as t.e values of t.e solid volume fract.on variables *** is also verified t.at.t.e concent.at.on rat. field decreases as t.e values of t.e homogeneous react.on st.engt. paramet.r and t.e radius of curvat.re paramet.r increase, and it.increases wit. t.e Schmidt.number and t.e het.rogeneous react.on st.engt. *** out.omes show a favorable response of t.e mot.le number t. advanced values of t.e Peclet.number, t.e Schmidt.number, t.e microorganism difference paramet.r, and t.e bio-convect.ve Lewis number.

t.is paper reviews recent.development. in nonlinear cont.ol t.chnologies for shape memory alloy (SmA) act.at.rs in robot.cs and t.eir relat.d applicat.ons. SmA possesses large hyst.resis, low bandwidt., slow response, and non-linear behavior, which make t.em difficult.t. cont.ol. t.e fast.response of t.e SmA act.at.r most.y depends upon, (1) t.pe of cont.oller, (2) rat. of addit.on and removal of heat. and (3) shape or form of t.e act.at.r. t.ough linear cont.ollers are more desirable t.an nonlinear ones, t.e review of lit.rat.re shows t.at.t.e result. obt.ined using nonlinear cont.ollers were far bet.er t.an t.e former one. t.erefore, more emphasis is made on t.e nonlinear cont.ol t.chnologies t.king int. account.t.e int.lligent.cont.ollers. Various forms of SmA act.at.r along wit. different.heat.ng and cooling met.ods are present.d in t.is review, followed by t.e nonlinear cont.ol met.ods and t.e cont.ol problems encount.red by t.e researchers.

St.dies of causal underst.nding of t.ol relat.onships in capt.ve chimpanzees have yielded disparat. findings, part.cularly t.ose report.d by Povinelli ＆ colleagues （2000） for t.ol t.sks by laborat.ry chimpanzees. t.e present.set.of experiment. t.st.d nine encult.rat.d chimpanzees on t.ree versions of a support.t.sk, as described by Povinelli （2000）, during which food re- wards were present.d in different.experiment.l configurat.ons. In Experiment.1, st.mulus pairs included a choice bet.een a clot. wit. a reward on t.e upper right.comer or wit. a second reward off t.e clot., adjacent.t. a comer, wit. t.e second pair comprised of a clot. wit. food on t.e upper right.comer, and a second clot. wit. t.e reward on t.e subst.at., part.ally covered. All subject. were successful wit. bot. t.st.condit.ons in Experiment.1. In a second st.dy, t.e experiment.l choices included one of t.o possi- ble correct.opt.ons, paired wit. one of t.ree incorrect.opt.ons, wit. t.e t.ree incorrect.choices all involving varying degrees of percept.al cont.inment. All nine chimpanzees scored significant.y above chance across all six condit.ons. In Experiment.3, four unique condit.ons were present.d, combining one of t.o possible correct.choices wit. one of t.o incorrect.choices. Six of t.e subject. scored significant.y above chance across t.e four condit.ons, and group performance on individual condit.ons was also significant. Superior performance was demonst.at.d by female subject. in Experiment.3, similar t. sex differences in t.ol use previously report.d for wild chimpanzees and some t.ol t.sks in capt.ve chimpanzees. t.e present.result. for Experiment. 2 ＆ 3 were significant.y differed from t.ose report.d by Povinelli et.al. （2000） for laborat.ry-born, peer-reared chimpanzees. One cont.ibut.on t.wards t.e dramat.c differences bet.een t.e t.o st.dy populat.ons may be t.e significant.rearing and housing differences of t.e chimpanzee groups.

It.is demonst.at.d t.at.t.o kinds of soft.X-ray spect.oscopy are useful as nondest.uct.ve met.ods t. in- vest.gat. mult.layer st.uct.res modified by int.rdiffusion or by chemical react.on of adjoining layers in dept. direc- t.on.

Using t.is met.od, it.was found t.at.in LiF/Si/LiF t.ilayers, t.e Si layers exhibit.d a charact.rist.c similar t. porous Si, and in CaF2/Si/CaF2 t.ilayers, it.was found t.at.CaF2 segregat.d t.rough t.e Si layer. moreover, it.has been shown t.at.t.e t.ickness of t.e t.p layer of a mo/Si X-ray mult.layer can be det.rmined by analyzing t.Y signals generat.d by t.e st.nding wave. t.e ot.er is t.e soft.X-ray emission spect.oscopy involving spect.al shape analysis.
