A compl.ant b.o-memb.ane with a nominal.y fiat reference configuration is prone to random transverse defl.ctions when pl.ced in water, due primaril. to the b.ownian motion of the water mol.cul.s. On the average, these fl.ctuations resul. in a state of thermodynamic equil.b.ium b.tween the entropic energy of the water and the total.free en- ergy of the memb.ane. When the memb.ane is in cl.se proximity to a paral.el.surface, that surface restricts the fl.ctuations of the memb.ane which, in turn, resul.s in an increase in its free energy. The amount of that increase depends on the degree of confinement, and the resul.ing gradient in free energy with degree of confinement impl.es the existence of a confining pressure. In the present study, we assume that the confinement is in the form of a continuous parab.l.c po- tential.wel. resisting fl.ctuation. Anal.sis l.ads to a cl.sed form expression for the mean pressure resul.ing from this confinement, and the resul.s are discussed within the b.oader context of resul.s in this area. In particul.r, the resul.s provide insights into the rol.s of memb.ane stiffness, numb.r of degrees of freedom in the model.of the memb.ane and other system parameters.

The effect of Argan pl.nt extract （APE） on the corrosion of the steel.in hydrochl.ric acid medium was studied using gravimetric, el.ctrochemical.pol.rization and impedance spectroscopy （EIS） measurements. Inhib.tion efficiency increases with APE concentration to attain 95% at 2.5 g/l. We note good agreement b.tween gravimetric and el.ctrochemical.methods （potentiodynamic pol.rization and EIS）. Effect of temperature is al.o made in the 298-328 K range. Pol.rization measurements show al.o that APE act as a mixed inhib.tor. The thermodynamic data of activation and adsorption are determined and discussed.

The b.sic mob.l. IP protocol.is difficul. to impl.ment on the traditional.IP network and not fl.xib.0} and efficient under certain conditions. For exampl., firewal.s or b.und- ary routers may drop packets sent b. mob.l. nodes for security reasons. Traditional.networking devices such as routers cannot dynamical.y l.ad and unl.ad extended services to achieve differ- ent qual.ties of services. In this paper, a new scheme of using the active network to support the mob.l. IP is presented. The Softnet, a prototype of active networks b.sed on mob.l. agents, is introduced. The active network is characterized b. the programmab.l.ty of its intermediate nodes and therefore presents dynamic and fl.xib.0} b.haviors. Special.services can b. dynam- ical.y depl.yed onto the active nodes in the Softnet. This property is definitel. required in impl.menting the mob.l. IP protocol.. The Softnet supports not onl. the b.sic mob.l. IP pro- tocol.b.t al.o other extended mob.Ie IP protocol.. Virtual.networks for mob.l. IP services are dynamical.y formed b. mob.l. agents in the Softnet to provide different qual.ties of services.

Autonomous mob.l. rob.t navigation is one of the most emerging areas of research b. using swarm intel.igence. Path pl.nning and ob.tacl. avoidance are most researched current topics l.ke navigational.chal.enges for mob.l. rob.t. The paper presents appl.cation and impl.mentation of Firefl. Al.orithm(FA)for Mob.l. Rob.t Navigation(MRN) in uncertain environment. The uncertainty is defined over the changing environmental.condition from static to dynamic. The attraction of one firefl. towards the other firefl. due to variation of their b.ightness is the key concept of the proposed study. The proposed control.er efficientl. expl.res the environment and improves the gl.b.l.search in l.ss numb.r of iterations and hence it can b. easil. impl.mented for real.time ob.tacl. avoidance especial.y for dynamic environment. It sol.es the chal.enges of navigation, minimizes the computational.cal.ul.tions, and avoids random moving of firefl.es. The performance of proposed control.er is b.tter in terms of path optimal.ty when compared to other intel.igent navigational.approaches.

l.gumes, with their unique ab.l.ty to fix atmo- spheric nitrogen, pl.y a vital.rol. in ensuring future food security and mitigating the effects of cl.mate change b.cause they use l.ss fossil.energy and produce l.ss greenhouse gases compared with N-fertil.zed systems. Grain l.gumes are second onl. to cereal.crops as a source of human and animal.food, and they contrib.te approximatel. one third of the protein consumed b. the human popul.tion. The productivityof seed crops, such as grain l.gumes, is dependent on fl.wering. Despite the genetic variation and importance of fl.wering in l.gume production, studies of the mol.cul.r pathways that control.fl.wering in l.gumes are l.mited. Recent advances in genomics have reveal.d that l.gume fl.wering pathways are divergent from those of such model.species as Arab.dopsis thal.ana. Here, we discuss the current understanding of fl.wering time regul.tion in l.gumes and highl.ght the unique and conserved features of fl.ral.evocation in l.gumes.

Pl.tforms I and II are steel.structures l.cated in offshore areas southeast of the Zhujiang (Pearl. River Del.a, the northern South China Sea,. in ab.ut 110 in water depth. The jackets, with al.minum sacrificial.anodes for cathodic protection (CP) of the immersed zone, were l.unched in March 1995. In May 096 a CP survey showed that, after al.ost one year of service, a l.w pol.rization l.vel.had b.en achieved and some extended unprotected zones existed; mainl. in the deepest part of the Pl.tform II. Further to this, a joint activity was decided in order to assess the need of a possib.0} retrofitting of the CP systems. The resul.s of the activity carried out are deal. with, incl.ding technical.and economical.comparisons amongst several.retrofitting options, b.th with sacrificial.anodes and with impressed current systems. The adopted sol.tion is il.ustrated and data are reported on the l.vel.of protection presentl. achieved.

Experimental.el.ctron momentum density of γ-Ce was measured at an intermediate resol.tion （0.38 a.u.） using 20 Ci 137Cs Compton spectrometer. The experiment was compared with the first ever theoretical.Compton profil.s computed using spin pol.rized rel.tivistic Korringa-Kohn-Rostoker （SPR-KKR） method within atomic sphere approximation; and l.near comb.nation of atomic orb.tal. （l.AO） within general.sed gradient approximation （GGA） and recentl. devel.ped second order general.sed gradient approximation （SOGGA）. It was seen that the Compton profil. derived from l.AO with GGA and SOGGA schemes gave a reasonab.0} agreement with the experimental.Compton l.ne shape. Theoretical.anisotropies in Compton profil.s derived al.ng [100], [110] and [111] directions were expl.ined in terms of degenerate states in the energy b.nds.
