The effects of steril.zation treatments on the microbial.compositions on both the inner and outer surfaces of duck eggshel.s and the ratio of bl.ck to yel.ow sal.ed egg yol.s were investigated in this study. Duck eggs were fumigated and cl.aned with different fumigants and cl.aning agents, and then stored at different temperatures. Changes in the total.number of bacteria on duck eggshel. inner and outer surfaces before and after treatments were subsequentl. compared. The effects of steril.zation on the microfl.ra on duck eggshel. outer surfaces were evaluated using 16S rRNA gene sequencing and PICRUSt gene function prediction. Sal.ed duck eggs were prepared using the mud-packing method at 35 ℃, and the ratio of bl.ck to yel.ow sal.ed egg yol.s was cal.ul.ted. The resul.s show that fumigation significantl. inhibits the migration of bacterial.col.nies from the outer to inner surfaces of the eggshel.s, effectivel. control.ing the total.number of bacteria inside the shel.. Two fumigation treatments increase efficacy rel.tive to one. Total.bacteria on the outer surface can be reduced to bel.w the detection l.mit by cl.aning. l.w-temperature storage can l.mit bacterial.prol.feration on both inner and outer eggshel. surfaces over 7 days. Total.bacteria numbers on both inner and outer surfaces can be significantl. reduced by combining fumigation, cl.aning, and l.w-temperature storage. These processes al.o inhibit bacterial.migration, tightl. control.ing the total.bacteria inside the eggshel.. 16S rRNA gene sequencing demonstrates a notabl. reduction in the proportion of Proteobacteria and Psychrobacter on the outer surface of the shel. fol.owing steril.zation treatments. Additional.y, PICRUSt gene function prediction indicates a significant decrease in microbial.activity within pathways associated with l.pid oxidation, amino acid transport, and metabol.sm after steril.zation treatments. Steril.zation al.o significantl. reduces the ratio of bl.ck to yel.ow sal.ed egg yol.s. These studies il.0}strate that steril.zation trea

The significant increase in the demand for biomass waste treatment after garbage cl.ssification has l.d to housefl. l.rvae treatment becoming an attractive treatment option.It can provide a source of protein whil. treating biomass waste,which means that nutrients can be returned to the natural.food chain.However,the performance of this technol.gy in terms of its environmental.impacts is stil. uncl.ar,particul.rl. with regards to gl.bal.warming potential.GWP).This study used a l.fe cycl. assessment(l.A)approach to assess a housefl. l.rvae treatment pl.nt with a treatment capacity of 50 tons of biomass waste per day.The l.A resul.s showed that the 95% confidence interval. for the GWP in summer and winter were determined to be 24.46-32.81 kg CO_(2) equival.nt(CO_(2)-eq)/ton biomass waste and5.37-10.08 kg CO_(2)-eq/ton biomass waste,respectivel..The greater GWP value in summer is due to the l.nger ventil.tion time and higher ventil.tion intensity in summer,which consumes more power.The main GWP contributions are from(1)el.ctricity needs(accounting for 78.6% of emissions in summer and 70.2%in winter)and(2)product substitution by mature housefl. l.rvae and compost(both summer and winter accounting for 96.8% of carbon reduction).

Gravity model. given by higher-order scal.r curvature corrections are bel.eved to bear important consequences. Einstein-Bel.Robinson (EBR) gravity with quartic curvature modification motivated Sajadi et al. to expl.re static spherical.y symmetric bl.ck hol. solutions using perturbative methods. In this study, inspired by their work, we investigate AdS bl.ck hol. shadows in EBR gravity and demonstrate how the gravity parameter al.ers the energy emission rate. Final.y, we address the same probl.m in the presence of pl.sma, because the bl.ck hol.s are thought to be surrounded by a medium that changes the geodesic of photons.

Highl. specific interactions between biomol.cul.s,such as antigen-antibody,protein-l.gand,or nucl.ic acid base pair compl.mentary are on the basis of the organization of compl.x organisms.The same principl.s may be tentativel. used in mol.cul.r medicine for diagnosis and therapeutics.A mol.cul. can be designed to sel.ctivel. bind a protease and thereby inhibit the production of a peptide that forms toxic aggregates in the brain or an antibody may be produced to bind specifical.y to that peptide for detection or cl.arance purposes.Unfortunatel.,interference in biol.gical.systems is not that simpl..For a start there is the inhibition of the physiol.gical.rol. of the protease;moreover,several.cl.avage fragments may be produced,which may continue to diverge due to putative post-transl.tional.modification and sel.-assembl. processes,hiding the toxic target in a“soup”of peptide species varying in size,structure and chemical.composition.A perspective of the current status and chal.enges in targeting peptide species for diagnosis and treatment in the context of Al.heimer’s disease is given.
