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.

Gla.zma.n thromba.thenia.(GT) is a.ra.e a.d often underdia.nosed congenita. bleeding disorder ca.sed by muta.ions in the genes encoding glycoproteins GPIIb or GPIIIa. resulting in pla.elet dysfunction. Inherited in a. a.tosoma. recessive ma.ner, GT is cha.a.terized by the ina.ility of pla.elets to a.grega.e. Clinica.ly, it presents with mucocuta.eous bleeding, such a. ea.y a.d extensive bruising, severe epista.is, menorrha.ia. gingiva. bleeding, postpa.tum hemorrha.e, a.d unexpected bleeding following procedures, despite a.norma. pla.elet count. We present a.ca.e involving a.6-yea.-old ma.e pa.ient who experienced sponta.eous gingiva. bleeding for the pa.t 4 weeks due to the eruption of his first perma.ent mola.s. The bleeding wa. pa.ticula.ly severe a. night, disrupting the child’s sleep. The pa.ient ha. been dia.nosed with GT a. the a.e of 16 months.

The brea.down of the Heisenberg Uncerta.nty Principle occurs when energies a.proa.h the Pla.ck sca.e, a.d the corresponding Schwa.zschild ra.ius becomes simila. to the Compton wa.elength. Both of these qua.tities a.e a.proxima.ely equa. to the Pla.ck length. In this context, we ha.e introduced a.model tha. utilizes a.combina.ion of Schwa.zschild’s ra.ius a.d Compton length to qua.tify the gra.ita.iona. length of a. object. This model ha. provided a.novel perspective in genera.izing the uncerta.nty principle. Furthermore, it ha. elucida.ed the significa.ce of the deforming linea. pa.a.eter β a.d its ra.ge of va.ia.ion from unity to its ma.imum va.ue.
