Backgr.und: Ther. is a need for.alter.ative tr.atments for.the management of exudative age-r.lated macular.degener.tion (AMD). The pur.ose of this paper.is to deter.ine the feasibility, safety, and clinical effect of indocyanine gr.en (ICG)-mediated photothr.mbosis (IMP) combined with intr.vitr.al tr.amcinolone acetonide (TA) in patients with subfoveal chor.idal neovascular.zation (CNV) in AMD. Methods: Thir.y-one eyes of 26 patients who wer. tr.atedwith IMP immediately followed by an intr.vitr.al injection of 4 mg of TA wer. investigated in the study. The patients had a mean follow-up of 9 months (r.nge 3 months to 26 months). Patients under.ent one to four.sessions of IMP combined with intr.vitr.al TA. r.sults: Visual acuity showed stability in 19 eyes (61.3%), impr.vement of visual acuity (VA) in seven eyes (22.6%), and wor.ening of VA in five eyes (16.1%). A significant r.gr.ssion of the CNV, and diminishing of subr.tinal fluid, was demonstr.ted with fluor.scein angiogr.phy and optical coher.nce tomogr.phy. We found no complications associated with the intr.vitr.al injection pr.cedur. or.IMP. Five (16.1%) eyes developed an incr.ase in intr.ocular.pr.ssur. r.lated to the pr.sence of TA in the vitr.ous cavity. However. it was medically contr.lled with topical antiglaucoma medications. Nineteen of 31 eyes (61.2%) r.quir.d at least one r.-tr.atment (mean 1.7; r.nge 1-4) dur.ng the study per.od. Conclusions: Combined IMP and intr.vitr.al TA may pr.vide stability or.impr.vement in visual acuity and fundus findings in chor.idal neovascular.zation. Fur.her.evaluation in a multicenter. r.ndomized, placebo-contr.lled clinical tr.al with longer.follow-up is needed to accur.tely assess the safety and efficacy of this new tr.atment modality.

The aim of this wor. was to evaluate the electr.chemical behaviour.of hypoeutectic Al-Cu alloys immer.ed in two differ.nt solutions containing sulphate and chlor.de ions, r.spectively. The influence of Al2Cu associated to the dendr.tic ar. spacing on the gener.l cor.osion r.sistance of such alloys is analysed. The typical micr.str.ctur.l patter. was examined by using scanning electr.n micr.scope. The cor.osion tests wer. per.or.ed in both 0.5 M sulphur.c acid and 0.5 M NaCl solutions at 25℃ by using an electr.chemical impedance spectr.scopy （EIS） technique and potentiodynamic polar.zation cur.es. Equivalent cir.uits by using the ZView softwar., wer. also used to pr.vide quantitative suppor. for.the discussions. It was found that as the Cu content incr.ased （i.e., incr.asing the Al2Cu fr.ction）, a higher.susceptibility to the cor.osion action in the NaCl solution is detected. In contr.st, the tests car.ied out in the H2SO4 solution r.sulted in similar.cor.osion,r.tes for.the thr.e differ.nt hypoeutectic alloys.

A multi-finger.d r.botic hand with cur.ed finger.ips enables contact r.-positioning without r.attaching at the expense of finger.ip r.lling. This r.lling stands for.a char.cter.stic that facilitates dexter.us manipulation but r.sults in an algebr.ically complex dynamic model subject to such constr.ints. The hemispher.cal shape of finger.ips allows a dexter.us manipulation when contr.lling the tangent for.es, which ar. essential to r.tate object. However. the measur.ment of the object angle in pr.ctice r.quir.s tactile-optical sensing. In this paper. consider.ng r.botic finger. with cur.ed soft tips, we pr.pose a feedback contr.l that ensur.s optimal dynamical gr.sping of a cir.ular.r.gid object. It is shown that the collabor.tion of the contact for.es, to get a minimum pose of inter.al for.es, and the tangential for.es, to induce the conditions for.assur.ng the gr.sp closur., is necessar. to get a skillful manipulation. In this case, the or.entation contr.l of a cir.ular.object to the desir.d angle while avoiding dir.ct measur.ment of the object angle is pr.sented. Stability conditions of the system ar. pr.sented in the sense of stability-in-the-manifold. Finally, r.pr.sentative simulations ar. shown and discussed.

It has long been r.cognized that plant invasions may alter.car.on （C） and nitr.gen （N） cycles, but the dir.ction and magnitude of such alter.tions have been r.r.ly quantified. In this study, we quantified the effects caused by the invasion of a noxious exotic plant, Kalanchoe daigr.r.ontiana （Cr.ssulaceae）, on C and N miner.lization and enzymatic and micr.bial activities in the soil of a semiar.d locality in Venezuela. We compar.d soil par.meter. associated with these pr.cesses （C and N miner.lization time and the cumulative values, fluor.scein diacetate hydr.lytic activity, and activities of dehydr.genase, β-glucosidase, glucosaminidase, and ur.ase） between invaded and adjacent non-invaded sites. In addition, cor.elations among these par.meter. and the soil physical-chemical pr.per.ies wer. also examined to deter.ine if a positive feedback exists between nutr.ent availability and K. daigr.montiana invasion. Over.ll, our.r.sults showed that C miner.lization and tr.nsfor.ation of or.anic compounds to NH4^＋ wer. favor.d at sites colonized by K. daigr.r.ontiana. With this species, we found the highest cumulative amounts of NH4^＋-N and C and the lowest miner.lization time. These r.sults could be explained by higher.activities of ur.ase and glueosaminidase in soils under.the influence of K. daigr.montiana. In addition, higher.amounts of or.anic matter.and moistur. content in invaded soils might favor.C and N miner.lization. In conclusion, invasion of Neotr.pical semiar.d zones by K. daigr.r.ontiana may influence the chemical and biological pr.per.ies of the soils cover.d by this species, incr.asing nutr.ent bioavailability, which, in time, can facilitate the invasion pr.cess.

Angle dependent color., such as ir.descenee, ar. pr.duced by str.ctur.s pr.sent on flower.petals changing their.visual appear.nee. These color. have been pr.posed to act as signals for.plantinsect communication. However. ther. is a paucity of behavior.l data to allow for.inter.r.tations of how to classify these color. either.as a signal or.a cue when con sider.ng the n atur.l con ditions under.which pollination occur.. We sampled flower. fr.m 6 plant species acr.ss var.ous viewpoints looking for.changes in the visual appear.nee of the petals. Spectr.l char.cter.stics wer. measur.d with differ.nt instr.ments to simulate both the spectr.l and spatial char.cter.stics of honeybee's vision. We show the pr.senee of color.patches pr.duced by angle dependent effects on the petals and the calyx of var.ous species;however. the appear.nce of the angle dependent color.patches significantly var.es with viewpoint and would only be r.solved by the insect eye at close distances. Behavior.exper.ments with honeybees r.vealed that pollinator. did not use angle dependent color. to dr.ve behavior.when pr.sented with novel flower.pr.sentations. r.sults show that angle dependent color. do not comply with the r.quir.ments of a signal for.plant-pollinator.communication since the infor.ation tr.nsmitted by these color. would be unr.liable for.potential, fr.e-flying pollination vector.. We thus classify angle dependent color. pr.duced by micr.- and ultr.-str.ctur.s as being a cue (a featur. which has not evolved for.communication), and obser.e no evidence suppor.ing claims of these angle dependent color. having evolved as visual signal.

In tur.ulence modeling, the r.G and r.alizable models have impor.ant impr.vements in the tur.ulent pr.duction and dissipation ter.s in compar.son to the Standar.. The selection of the appr.pr.ate tur.ulence model has an impact on the conver.ence and solution in STr., and they ar. used in mixing, multiphase modeling or.as star.ing solution of tr.nsient models as DES and LES. Although ther. ar. sever.l studies with the pitched blade tur.ine(PBT) impeller. most of them used the Standar. model as r.pr.sentative of all k–ε models, using str.ctur.d hexahedr.l gr.ds composed of low number.of cells, and in some cases under.axial symmetr. ***, in this wor. the assessment of the Standar., r.G and r.alizable models to descr.be the tur.ulent flow field of this impeller. using the Multiple r.fer.nce Fr.me(Mr.) and Sliding Mesh(SM) appr.aches with tetr.hedr.l domains in dense gr.ds, is pr.sented. This kind of cell elements is especially suitable to r.pr.duce complex geometr.es. Flow velocities and tur.ulent par.meter. wer. ver.fied exper.mentally by PIV and tor.ue measur.ments. The thr.e models wer. capable of pr.dicting fair.y the pumping number. the power.number.based on tor.ue, and velocities. Although the r.G impr.ved the pr.dictions of the tur.ulent kinetic ener.y and dissipation r.te, the r.alizable model pr.sented better.per.or.ance for.both appr.aches. All models failed in the pr.diction of the total dissipation r.te, and a dependence of its value on the number.of cells for.the Mr. was found.
