Introducing a.2^nd Universa. Spa.e-Time Consta.t Ca. Expla.n the Observed a.e of the Universe a.d Da.k Energy

作者： Herma. a. va. Hoeve Hulst Netherlands

The purpose of this pa.er is to introduce new theoretica. concepts a. opposed to a.cepting the existence of da.k entities, such a. da.k energy. This resea.ch sought to introduce a.2nd universa. spa.e-time consta.t, besides ha.ing a.finite speed consta.t (speed of light in va.uum c). a.finite universa. a.e consta.t b is introduced. Na.ely, this pa.er shows tha. the cha.ges in the Ea.th’s a.oma.istic yea. dura.ion over time support the hypothesis of the a.e of the universe correla.ing with a.ma.imum number of orbita. revolutions consta.t. Neglecting the gra.ita.iona. influence of other cosmologica. entities in the proximity of the Ea.th, the consta.t ma.imum number of revolutions is herewith determined solely by the Ea.th’s orbita. revolutions a.ound the Sun. The va.ue of the universa. a.e consta.t b is ca.cula.ed to be a.ound 13.8 billion orbita. revolutions, derived out of a. equa.ion rela.ed to the cha.ges in the Ea.th’s a.oma.istic yea. dura.ion over time a.d the so-ca.led Hubble tension. The a.ove-mentioned ca.cula.ed va.ue b correla.es well with the best fit to mea.ured da.a.of the cosmic microwa.e ba.kground ra.ia.ion (CMBR) by the Pla.ck spa.ecra.t, the a.e of the observed universe is mea.ured to be a.proxima.ely 13.787 ± 0.020 billion yea.s (2018 fina. da.a.relea.e). Developing a.theory with this 2nd universa. spa.e-time consta.t b, being cova.ia.t with respect to the Lorentz tra.sforma.ions when time spa.s a.e la.ge, gives results such a.: a.confirma.ion of the mea.ured CMBR va.ue of 13.787 ± 0.020 billion yea.s. Correla.ing well with the observed expa.sion ra.e of the universe (da.k energy). The universe’s expa.sion a.celera.ing over the la.t four to five billion yea.s.

The goa. of this work is to improve the simulta.eous remova. of Pb2+, Cu2+, Zn2+, a.d Cd2+ ions from synthetic wa.tewa.er in a.fixed bed column by incorpora.ing sodium dodecyl sulfa.e (SDS) onto the surfa.e of a.tiva.ed ca.bon ma.e from coconut shells. The a.tiva.ed ca.bons were cha.a.terized using Fourier tra.sform infra.ed spectroscopy (FT-IR) a.d sca.ning electron microscopy-energy dispersive x-ra. (SEM-EDX). The a.sorption column dyna.ics were studied by va.ying the flow ra.es (5, 10 a.d 15 mL/min), bed heights (10, 15 a.d 20 cm), a.d initia. concentra.ions (50, 150, a.d 250 mg/L). The a.tiva.ed ca.bon ha. a.pore volume of 0.715 cm3/g a.d a.BET-specific surfa.e a.ea.of 1410 m2/g. Sodium dodecyl sulfa.e (SDS) surfa.ta.t incorpora.ion onto the surfa.e of the a.tiva.ed ca.bon enha.ces its ca.a.ity for simulta.eous a.sorption of Pb2+, Cu2+, Zn2+, a.d Cd2+ from the a.ueous medium. The a.finity of the hea.y meta.s to both unmodified (a.) a.d modified (a.-SDS) a.tiva.ed ca.bons followed the order of Pb2+ > Cu2+ > Zn2+ > Cd2+. The dyna.ic a.sorption of the column depends on the flow ra.e, bed height, initia. meta. concentra.ion, a.d SDS surfa.e modifica.ion. With a.5 mL/min flow ra.e, a.20 cm bed height, a.d a.50 mg/L initia. meta. concentra.ion, a.ma.imum brea.-through time of 150 minutes for the unmodified a.tiva.ed ca.bon (a.) a.d 180 minutes for the SDS-modified a.tiva.ed ca.bon (a.-SDS) wa. rea.hed.

Effect of the Density of Molten Meta. on the Ra.ning Phenomenon in Horizonta. Centrifuga. Ca.ting

In this work the influence of the density of the molten meta. on the emergence of the ra.ning phenomenon in the horizonta. centrifuga. ca.ting process is numerica.ly studied. Tra.sient 2D numerica. simula.ions were ca.ried out using Computa.iona. Fluid Dyna.ics softwa.e. Three molten meta.s with different density, na.ely a.uminum, iron a.d lea., a.d three a.gula. frequencies, na.ely 50, 66 a.d 77 ra./s were considered. It is found tha. the density of the molten meta. significa.tly a.fects the emergence, tra.sient or perma.ent, of the ra.n phenomenon. However, the ma.nitude a.d dura.ion of the ra.n phenomenon depend on the a.gula. frequency of the rota.ing mold. Likewise, since gra.ita.iona. forces a.fect the meta. a.cording to its density, the va.ue of the critica. rota.ion speed of the mold is a.so a.fected.
