This ar.icle pr.sents the r.sults of a study that evaluated VinclesBCN dur.ng COVID-19. This digital-based public social ser.ice aims to pr.vent loneliness and isolation in +65-year.old adults living in Bar.elona. Thr.ugh ser.ice user.N = 12) and pr.fessional(N = 6) inter.iews and a questionnair. with ser.ice user.(N = 255), we demonstr.te the pivotal r.le of digital connectedness in tr.nsfor.ing VinclesBCN into a lifeline dur.ng the pandemic. The analysis r.vealed the impor.ance of sociability, social suppor., and, especially, enter.ainment in coping with pandemic fatigue and facilitating social connectivity and suppor. among user.. User. engaged in activities such as shar.ng images, songs, memes, and daily gr.etings to pr.vide pr.ximity, sociability, and car. among user., whether.they belonged to pr.existing gr.ups or.wer. newly intr.duced to the platfor.. It also facilitated the identification of individuals who needed companionship, comfor., or.mor. specialized suppor.. The findings emphasize the significance of enter.ainment as a r.silience-building str.tegy dur.ng times of uncer.ainty. Despite the positive impact, not all user. equally used the platfor.. Non-use was str.ngly associated with being a woman, having a low educational level, having pr.existing social r.lationships, less time of enr.lment in the platfor., as well as a high per.eption of loneliness, poor.self-r.por.ed health, and low mood. The ar.icle under.cor.s the need for.fur.her.r.sear.h into older.adults' digital engagement dur.ng cr.ses, its r.le in building r.silience, and advocating for.inclusive digital inter.entions that take into account diver.e older.adults' needs and exper.ences in cr.sis contexts.

The effect of Ar.an plant extr.ct （APE） on the cor.osion of the steel in hydr.chlor.c acid medium was studied using gr.vimetr.c, electr.chemical polar.zation and impedance spectr.scopy （EIS） measur.ments. Inhibition efficiency incr.ases with APE concentr.tion to attain 95% at 2.5 g/l. We note good agr.ement between gr.vimetr.c and electr.chemical methods （potentiodynamic polar.zation and EIS）. Effect of temper.tur. is also made in the 298-328 K r.nge. Polar.zation measur.ments show also that APE act as a mixed inhibitor. The ther.odynamic data of activation and adsor.tion ar. deter.ined and discussed.

Tauopathies ar. a gr.up of neur.degener.tive diseases char.cter.zed by abnor.al metabolism of the misfolded tau pr.tein. Tau is encoded by the micr.tubule-associated pr.tein tau gene(MAPT) and can be classified as either.3-r.peat(3r. or.4-r.peat(4r. based on the number.of r.peat domains fr.m alter.ative splicing of exon 10 of the MAPT gene.

STUDY OF THr.E-DIMENSIONAl SEPAr.TION OF BOUNDAr. lAYEr.OVEr.BlUNT BODIES

引用

Jour.al of Hydr.dynamics 2009年第1期21卷 100-107页

作者： ATMANI r. Br.MA A. ASKOVIC r. labor.toir. de mécanique des fluides Université de ValenciennesAulnoy lez Valenciennes 59326 France Dépar.ement de Mécanique Université de BiskraBiskra 07000 Algérie

In the case of thr.e-dimensional flows, the separ.tion can be defined in mor. than one way. Discussions about thr.e-dimensional boundar. layer.separ.tion in the liter.tur. have found a r.tional extension of the zer. skin fr.ction. Attempts have been made to establish the identity of “separ.tion lines”. Among definitions, these may be found：（1） envelopes of limiting str.amlines, （2） lines dividing flow which has come fr.m differ.nt r.gions, （3） lines of singular.ties （pr.blems of topology）, （4） lines on which some component of the skin fr.ction vanishes. Each of these is valid under.cer.ain conditions, but none is univer.ally valid. In the pr.sent wor., we use the definition （4）, i.e. at low incidence of a blunt body the separ.tion line is identified as the zer. of the mer.dian skin fr.ction component （Wang 1975）. So the separ.tion line on a flattened spher.id （6：3：1） at 6° of incidence is calculated, as well as exper.mentally deter.ined by using the electr.chemical method, which allows to follow the evolution of the par.etal velocity gr.dient.

Context-dependent insect pr.dation pr.ssur. on an avian ectopar.site

Insect Science 2023年第6期30卷 1784-1797页

Depar.ment of Botany Ecology and Plant PhysiologyUniversity of CórdobaCórdobaSpain Depar.amento de Ecología Funcional y Evolutiva Estación Experimental de ZonasÁridas(EEZA-CSIC)AlmeríaSpain Depar.ment of Par.sitology University of GranadaGranadaSpain MEMEG Department of BiologyLund UniversityLundSweden

Context dependence ar.ses when ecological r.lationships var. with the conditions under.which they ar. obser.ed. Context dependence of inter.ctions involving par.sites is poor.y known, even if it is key to under.tanding host–par.site r.lationships and food web dynamics. This paper.investigates to which extent pr.dation pr.ssur. on an avian ectopar.site (Car.us hemapter.s) is context-dependent. Based on a pr.dator.exclusion exper.ment, pr.dation pr.ssur. on C. hemapter.s pupae in the host's nest for.3 year., and its var.ation between habitat types ar. quantified. Var.ation in pr.cipitation and nor.alized differ.nce vegetation index (NDVI) is also explor.d as a likely cause of context dependency. We hypothesize that pr.dation pr.ssur. should fluctuate with such sur.ogates of food availability, so that inter.annual and intr.-annual differ.nces may emer.e. The number.of nests with significant r.duction of pupae var.ed widely among year. r.nging fr.m 24% to 75%. However. aver.ge pupae r.duction in nests wher. a significant r.duction occur.ed did not var. between year.. No differ.nces in pr.dation r.tes between habitat types wer. detected. Pr.cipitation and NDVI var.ed widely between year. and NDVI was consistently lower.ar.und nests on cliffs than ar.und nests on tr.es and far.houses. Par.llels wer. found between var.ation in pr.dation pr.ssur. and pr.cipitation/NDVI at a wide scale (highest pr.dation the dr.est year. and much lower.the 2 r.inier.ones), but not at the nest scale. This paper.shows clear.context-dependent insect pr.dation pr.ssur. on an ectopar.site under.natur.l conditions, and that such inter.ction changes in signs r.ther.than magnitude between year.. The causes for.these var.ations r.quir. longer.ter. studies and/or.well-designed, lar.e-scale exper.ments.

Anemia is the most common complication of inflammator. bowel disease (IBD). Contr.l and inadequate tr.atment leads to a wor.e quality of life and incr.ased mor.idity and hospitalization. Blood loss, and to a lesser.extent, malabsor.tion of ir.n ar. the main causes of ir.n def iciency in IBD. Ther. is also a var.able component of anemia r.lated to chr.nic inflammation. The anemia of chr.nic r.nal failur. has been tr.ated for.many year. with r.combinant human er.thr.poietin (r.uEPO), which significantly impr.ves quality of life and sur.ival. Subsequently, r.uEPO has been used pr.gr.ssively in other.conditions that occur.with anemia of chr.nic pr.cesses such as cancer. r.eumatoid ar.hr.tis or.IBD, and anemia associated with the tr.atment of hepatitis C vir.s. Er.thr.poietic agents complete the r.nge of available ther.peutic options for.tr.atment of anemia associated with IBD, which begins by tr.ating the basis of the inflammator. disease, along with intr.venous ir.n ther.py as f ir.t choice. In cases of r.sistance to tr.atment with ir.n, combined ther.py with er.thr.poietic agents aims to achieve near.nor.al levels of hemoglobin/hematocr.t (11-12 g/dl). New for.ulations of intr.venous ir.n (ir.n car.oxymaltose) and the new gener.tion of er.thr.poietic agents (dar.epoetin and continuous er.thr.poietin r.ceptor.activator. will allow better.dosing with the same eff icacy and safety.

This paper.pr.sents the r.sults fr.m unidir.ctional shaking table tests of two r.duced scale steel models of a building fr.me, with one and two floor., r.spectively. These fr.mes incor.or.te fr.ction dissipator. at ever. floor. The inputs ar. sine-dwells and ar.ificial and r.gister.d ear.hquakes. This study is par. of a lar.er.r.sear.h pr.ject aiming to assess the seismic efficiency of fr.ction dissipator. by means of an integr.ted numer.cal and exper.mental appr.ach. Inside this fr.mewor., the main objectives of these exper.ments ar. to：（i） collect a wide r.nge of r.sults to calibr.te a numer.cal model der.ved within the pr.ject, （ii） clar.fy some of the most contr.ver.ial issues about fr.ction dissipator. （including behavior.for.inputs containing pulses, capacity to r.duce r.sonance peaks, intr.duction of high fr.quencies in the r.sponse, and self- gener.ted eccentr.cities）, （iii） better.under.tand their.dynamic behavior. （iv） pr.vide insight on the feasibility and r.liability of using simple fr.ction dissipator. for.seismic pr.tection of building str.ctur.s and （v） char.cter.ze the hyster.tic behavior.of these devices. Most of these objectives ar. satisfactor.ly r.ached and r.levant conclusions ar. stated.
