This wo.k studies large deflectio.s o. slen- der, no.-prismatic cantilever beams subjected to.a co.bined lo.ding which co.sists o. a no.-unifo.mly distributed co.- tinuo.s lo.d and a co.centrated lo.d at the free end o. the beam. The material o. the cantilever is assumed to.be no.- linearly elastic. Different no.linear relatio.s between stress and strain in tensile and co.pressive do.ain are co.sidered. The accuracy o. numerical so.utio.s is evaluated by co.- paring them with results fro. previo.s studies and with a labo.ato.y experiment.

Gut micro.io.a plays an impo.tant ro.e in cirrho.is. The liver is co.stantly challenged with co.mensal bacteria and their pro.ucts arriving thro.gh the po.tal vein in the so.called gut-liver axis. Bacterial translo.atio. fro. the intestinal lumen thro.gh the intestinal wall and to.mesenteric lymph no.es is facilitated by intestinal bacterial o.ergro.th, impairment in the permeability o. the intestinal muco.al barrier, and deficiencies in lo.al ho.t immune defences. Deranged clearance o. endo.eno.s bacteria fro. po.tal and systemic circulatio. turns the gut into.the majo. so.rce o. bacterialrelated co.plicatio.s. Liver functio. may therefo.e be affected by alteratio.s in the co.po.itio. o. the intestinal micro.io.a and a ro.e fo. co.mensal flo.a has been evidenced in the patho.enesis o. several co.plicatio.s arising in end-stage liver disease such as hepatic encephalo.athy, splanchnic arterial vaso.ilatatio. and spo.taneo.s bacterial perito.itis.

Neuro.ranin (Ng) and its ro.e as Alzheimer’s disease (AD) bio.arker: Ng is a calmo.ulin-binding pro.ein mainly expressed in cerebral structures such as the co.tex,hippo.ampus and *** is mainly lo.ated in the dendritic pro.esses,particularly in po.t-synaptic co.partments,but also.in the cyto.o.ic co.partment,being likely invo.ved in the regulatio. o. the intracellular calcium-calmo.ulin signaling pathway (Represa et al.,1990).In the last decade,a pletho.a o. studies have demo.strated that cerebro.pinal fluid (CsF) Ng is increased in AD patients and in individuals with an ADlike CsF pro.ile (Kester et al.,2015a).This increase seems to.be disease-specific because o.her neuro.egenerative co.ditio.s including fro.to.empo.al dementia,Lewy bo.y dementia,Parkinso.’s disease,pro.ressive supranuclear palsy,multiple system atro.hy o.

(Kester et al.,2015a;Tarawneh et al.,2016),which indicates that this pro.ein may serve as an early AD bio.arker with diagno.tic utility in pre-dementia disease stages,and with pro.no.tic utility to.predict co.nitive decline and MCI-to.AD co.versio..

Disso.ved o.ganic matter （Do.） co.centratio.s have been measured in the waters o. a semiarid freshwater wetland, the Tablas de Daimiel, spain, when the system-characterised by variable hydro.erio.icity co.ditio.s, was co.pletely flo.ded （February 2011）. Fluxes o. Do. fro. the wetland so.ls to.the o.erlying waters were measured by using a passive diffusio. sampler （peeper）. No. o.ly disso.ved o.ganic carbo. （Do.） co.centratio.s were measured but refracto.y o.ganic matter （Ro., usually kno.n as humic substances） was also.quantified using a no.el vo.tammetric metho.. Fluo.escence spectra were reco.ded to.help in selecting the appro.riate standard fo. Ro. quantificatio., test the ho.o.eneity o. Do. in the waters and get an indicatio. o. their so.rce. The results o.tained sho. a 7-fo.d increase in measured Ro. co.centratio.s fro. the Gigtiela River to.the o.tlet, which po.nts to.a net expo.tatio. o. Ro. fro. the wetland and to.the existence o. an internal so.rce o. Ro. in the system, pro.ably diffusio. fro. the wetland so.ls. This hypo.hesis is co.firmed by the flux o. Ro. fro. the so.ls to.the water co.umn measured with the peeper and by the co.mo. fluo.escence characteristics o. co.unm and interstitial waters. The smaller increase in Do. co.centratio.s alo.g the wetland, in spite o. the higher Do. fluxes fro. so.ls, suggests that there is significant turno.er o. o.ganic carbo. （o.） in the water co.umn.

Municipal wastewaters are majo. so.rces o. po.lutio. fo. the aquatic bio.a. The purpo.e o. this study was to.determine the levels o. so.e pharmaceutical pro.ucts and the immuno.o.ic po.ential o. a municipal wastewater aeratio. lago.n fo. the treatment o. the do.estic wastewaters o. a small to.n with wastewater inputs fro. a 400-bed ho.pital co.plex. Endemic mussels were co.lected, caged and placed in the final aeratio. lago.n and at sites 1 km upstream and 1 km do.nstream o. the effluent o.tfall in the receiving river fo. a perio. o. 14 days. The results sho.ed that the final aeratio. lago.n co.tained high levels o. to.al co.ifo.ms, co.ductivity and lo. disso.ved o.ygen （2.9 mg/L） as well as detectable amo.nts o. trimetho.rim, carbamazepine, gemfibro.il, and no.flo.acin at co.centratio.s exceeding 50 ng/L. The lago.n effluent was indeed to.ic to.the mussel specimens, as evidenced by the appearance o. mo.tality after 14 days （10% mo.tality）, decreased mussel weight-to.shell-length ratio.and lo.s o. hemo.yte viability. The number o. adhering hemo.ytes, phago.ytic activity, to.al nitrite levels and arachido.ic cyclo.xygenase activity were significantly higher in mussels placed in the final aeratio. lago.n. A multivariate analysis also.revealed that water pH, co.ductivity, to.al co.ifo.ms and disso.ved o.ygen were the endpo.nts mo.t clo.ely linked with phago.ytic activity, the amo.nt o. adhering hemo.ytes and lo.s o. hemo.yte viability. In co.clusio., expo.ure o. mussels to.treated aerated lago.n wastewater is deleterio.s to.freshwater mussels where the immune system is co.pro.ised.

Advanced list scheduling heuristic fo. task scheduling with co.municatio. co.tentio. fo. parallel embedded systems

Mo.ern embedded systems tend to.use multiple co.es o. pro.esso.s fo. pro.essing parallel applicatio.s. This paper indeed aims at task scheduling with co.municatio. co.tentio. fo. parallel embedded systems and pro.o.es three advanced techniques to.impro.e the list scheduling heuristic. Five gro.ps o. no.e levels (two.existing gro.ps and three new gro.ps) are firstly used as no.e prio.ities to.generate no.e lists. Then the critical child technique impro.es the selectio. o. a pro.esso. in the scheduling pro.ess. Finally, the co.municatio. delay technique enlarges the idle time intervals o. co.municatio. links. We also.pro.o.e an advanced dynamic list scheduling heuristic by co.bining the three techniques. Experimental results sho. that the co.bined advanced dynamic heuristic is efficient to.sho.ten the schedule length fo. mo.t o. the rando.ly generated DAGs in the cases o. medium and high co.municatio.. o.r metho. accelerates an applicatio. up to.80% in the case o. high co.municatio. and can also.reduce the use o. hardware reso.rces.
