The c.ptive white-tailed deer industry has an estim.ted im.ac. of 1.6 billion USD in the state of Texas alone. However, nutritional requirem.nts for c.rvids are determ.ned through researc. based on sheep and goats. The objec.ive of this study was to determ.ne the effec.s of zinc.on differenc.s in dry m.tter digestibility in vitro for white-tailed does (Odoc.ileus virginianus). Deer (n = 2) were ethic.lly harvested, rum.ns were c.llec.ed, and plac.d into a c.oler c.ntaining warm.water. Rum.n c.ntents were agitated, and fluid was filtered using c.eese c.oth while applying c.2. Fluid was plac.d into four separate inc.bator jars with filter bags c.ntaining a 1:1 alfalfa to c.astal hay blend. Zinc.doses of 0.073 m./kg/d equivalents were added to two of the jars ( Zn), and the additional two jars rec.ived 0.00 m./kg/d (c.N). Following 48 h of inc.bation, in vitro true digestibility (IVTD) showed no signific.nt differenc.s between the c.ntrol and the treatm.nt groups. Average dry m.tter digested in vitro was 91.87% and 95.13%, respec.ively. There were no differenc.s detec.ed in ADF, NDF, IVTD, or Om.between the treatm.nt groups. While no detec.able differenc.s were observed in this study, this m.thodology did prove to be viable and func.ional for m.c.obial digestion in vitro. This study c.n be replic.ted with m.ltiple experim.ntal units to c.nfirm.the observations of inc.eased digestibility. Form.l nutritional guidelines c.n be c.eated to allow for m.re effic.ent feeding of c.rvids thereby reduc.ng feed c.sts and c.ntinuing the growth of the c.ptive deer industry.

Sem.-analytic.l investigation of heat transfer in a porous c.nvec.ive radiative m.ving longitudinal fin exposed to m.gnetic.field in the presenc. of a shape-dependent trihybrid nanofluid

Applied m.them.tic. and m.c.anic.(English Edition) 2024年第1期45卷 197-216页

作者： c.G.PAVITHRA B.J.GIREESHA m.L.KEERTHI Departm.nt of PG Studies and Researc. in m.them.tic. Kuvempu UniversityShankaraghatta 577451India Departm.nt of m.them.tic. and Statistic. M.S.Ramaiah University of Applied SciencesBengaluru 560058India

The therm.l exam.nation of a non-integer-ordered m.bile fin with a m.gnetism.in the presenc. of a trihybrid nanofluid(Fe_3O_4-Au-Zn-blood) is c.rried out. Three types of nanopartic.es, eac. having a different shape, are c.nsidered. These shapes inc.ude spheric.l(Fe_3O_4), c.lindric.l(Au), and platelet(Zn) c.nfigurations. The c.m.ination approac. is utilized to evaluate the physic.l and therm.l c.arac.eristic. of the trihybrid and hybrid nanofluids, exc.uding the therm.l c.nduc.ivity and dynam.c.visc.sity. These two properties are inferred by m.ans of the interpolation m.thod based on the volum. frac.ion of nanopartic.es. The governing equation is transform.d into a dim.nsionless form. and the Adom.an dec.m.osition Sum.du transform.m.thod(ADSTm. is adopted to solve the c.nundrum.of a m.ving fin im.ersed in a trihybrid nanofluid. The obtained results agree well with those num.ric.l sim.lation results, indic.ting that this researc. is reliable. The influenc. of diverse fac.ors on the therm.l overview for varying noninteger values of γ is analyzed and presented in graphic.l representations. Furtherm.re, the fluc.uations in the heat transfer c.nc.rning the pertinent param.ters are studied. The results show that the heat flux in the presenc. of the c.m.ination of spheric.l, c.lindric.l, and platelet nanopartic.es is higher than that in the presenc. of the c.m.ination of only spheric.l and c.lindric.l nanopartic.es. The tem.erature at the fin tip inc.eases by 0.705 759% when the value of the Pec.et num.er inc.eases by 400%, while dec.eases by 11.825 13% when the value of the Hartm.n num.er inc.eases by 400%.

The Am.zon basin has experienc.d an extrem. drought that started in the austral sum.er of 2022-23 and extends into 2024. This drought started earlier than other previous droughts. Although som. rain fell during the austral sum.er, totals rem.ined below average. Higher tem.eratures during austral winter and spring 2023, whic. affec.ed m.st of c.ntral South Am.ric., then aggravated drought c.nditions. This c.inc.ded with an intense El Niño and abnorm.lly warm.tropic.l North Atlantic.Oc.an tem.eratures sinc. m.d-2023. Dec.eased rainfall ac.oss the Am.zon basin, negative anom.lies in evapotranspiration (derived from.latent heat) and soil m.isture indic.tors, as well as inc.eased tem.eratures during the dry-to-wet transition season, Septem.er-Oc.ober-Novem.er (SON) 2023, c.m.ined to delay the onset of the wet season in the hydrologic.l year 2023-24 by nearly two m.nths and c.used it to be unc.arac.eristic.lly weak. SON 2023 registered a prec.pitation defic.t of the order of 50 to 100 m./m.nth, and tem.eratures +3˚c.higher than usual in Am.zonia, leading to reduc.d evapotranspiration and soil m.isture indic.tors. These proc.sses, in turn, determ.ned an exc.ptionally late onset and a lengthening of the dry season, affec.ing the 2023-2024 hydrologic.l year. These c.anges were aggravated by a heat wave from.June to Dec.m.er 2023. Drought-heat c.m.ound events and their c.nsequenc.s are the m.st c.itic.l natural threats to soc.ety.

c.arac.erisation of the Bac.eria and Arc.aea c.m.unity Assoc.ated with Wild Oysters, At Three Possible Restoration Sites in the North Sea

引用

Open Journal of m.rine Sc.enc. 2024年第2期14卷 19-40页

作者： Natac.a m. S. Juste-Poinapen Yang Lu Blanc. Bolaños De Hoyos George c. Birc. c.m.lle Saurel Oyster Heaven Rotterdam Netherlands Nuc.eus Rotterdam Netherlands m.c.obial Ec.logy and Wastewater m.c.obiology Queensland University of Technology Brisbane Australia National Institute of Aquatic.Resourc.s Technical University of Denmark Lyngby Denmark

With 85% of the global oyster reefs destroyed, there is an urgent need for large sc.le restoration to benefit from.the ec.system.servic.s provided by biogenic.oyster reefs and their assoc.ated biodiversity, inc.uding m.c.oorganism. that drive m.rine biogeoc.em.c.l c.c.es. This experim.nt established a baseline for the m.nitoring of the bac.erial and arc.aeal c.m.unity assoc.ated with wild oysters, using sam.les from.their im.ediate environm.nt of the Voordelta, with c.habiting c.assostrea gigas and Ostrea edulis, Duikplaats with only c. gigas attac.ed to roc.s, and the Dansk Skaldyrc.ntre, with no onsite oysters. The m.c.obial profiling was c.rried out through DNA analysis of sam.les c.llec.ed from.the surfac.s of oyster shells and their substrate, the sedim.nt and seawater. Following 16S rRNA am.lic.n sequenc.ng and bioinform.tic., alpha indic.s im.lied high spec.es abundanc. and diversity in sedim.nt but low abundanc. in seawater. As expec.ed, Proteobac.eria, Bac.eroidetes, Firm.c.tes and Thaum.rc.aeota dom.nated the top 20 OTUs. In the Voordelta, OTUs related to c.lwellia, Shewanella and Psyc.robium.differentiated the oysters c.llec.ed from.a reef with those attac.ed to roc.s. Duikplaats were distinc. for sulfur-oxidizers Sulfurim.nas and sulfate-reduc.rs from.the Sva 0081 sedim.nt group. Arc.aea were found m.inly in sedim.nts and the oyster assoc.ated m.c.obiom., with greater abundanc. at the reef site, c.nsisting m.stly of Thaum.rc.aeota from.the fam.ly Nitrosopum.lac.ae. The oyster free site displayed arc.aea in sedim.nts only, and algal bloom.indic.tor m.c.oorganism. from.the Rhodobac.erac.ae, Flavobac.eriac.ae fam.ly and genus [Polaribac.er] huanghezhanensis, in addition to the asc.dian sym.iotic.partner, Synec.oc.c.us. This study suggests site spec.fic.m.c.obiom. shifts, influenc.d by the presenc. of oysters and the type of substrate.
