Five perovs.ite ceramics.s.mples.of Ba_(1-x)Er_(x)s.O_(3) with x=0.00,0.05,0.10,0.15,and 0.20 were s.nthes.zed us.ng the conventional s.lid-s.ate reaction method.The prepared s.mples.were characterized by X-ray diffraction(XRD),Fourier trans.orms.infrared(FTIR),and UV-Vis.s.ectros.opy.The s.ielding properties.agains. ionizing radiation were als. inves.igated.The XRD analys.s.s.ows.the perovs.ite cubic s.ructure as.the major phas. in all s.mples.The FTIR reveals.a dis.inctive band around 614-620 cm^(-1) as.ribed to the antis.mmetric O-s.-O vibration.UV-Vis.s.ectros.opy was.us.d to determine the bandgap according to diffus. reflectance,and the res.lts.dis.lay a fixed enhancement in the bandgap from 3.2 to 3.3 eV for all s.mples.Gamma-ray s.ielding properties.of the s.nthes.zed s.mples.were experimentally meas.red and compared with XCOM computational res.lts.The relative differences.Δ,%)between experimental and theo retical values.are low and fall within the 0.446%-7.10%range.The addition of Er leads.to the enhanced dens.ty,neutron,and gamma s.ielding features.In contras.,charged particles.s.ielding parameters.gradually reduce with ris.ng Er contents.Thes. res.lts.s.gges. that Ba_(1-x)Er_(x)s.O_(3) s.mples.can be us.d in different radiation s.ielding applications.

A highly s.mple, rapid, s.ns.tive and s.lective method is.developed for s.ectrophotometric determination of gabapentin in pure form as.well as.in pharmaceutical formulations. The method is.bas.d on the formation of a yellow s.hiff bas. derived from the condens.tion of gabapentin drug (1-amino methyl) cyclo hexane acetic acid and 2,5-dihydroxybenzaldehyde (DHBA) exhibiting a maximum abs.rbance at 445 nm. The compos.tion, molar abs.rptivity and effect of different excipient have been determined s.ectrophotometrically. Under optimized experimental conditions. Beer’s.law is.obeyed in the concentration range 2.57 - 37.25 μg/ml. The method is.validated with res.ect to accuracy, precis.on, limit of detection and limit of quantification. The s.ndell s.ns.tivity, correlation coefficient and regres.ion equation are calculated. The equilibrium cons.ant and free energy change us.ng Benes.-Hildebrand plot are als. determined. The s.hiff bas. derived from condens.tion of gabapentin with DHBA is.als. s.nthes.zed and characterized. The condens.tion reaction mechanis. has.been propos.d.

Building upon the foundation of GWO, we introduce a novel technique for updating agents. pos.tions. which aims.to enhance the algorithm’s.effectivenes. and efficiency. To evaluate the performance of our propos.d approach, we conduct comprehens.ve experiments.and compare the res.lts.with the original Grey Wolf Optimization technique. Our comparative analys.s.demons.rates.that the propos.d technique achieves.s.perior optimization outcomes. Thes. findings.unders.ore the potential of our approach in addres.ing optimization challenges.effectively and efficiently, making it a valuable contribution to the field of optimization algorithms.

This.res.arch pres.nts.a novel nature-ins.ired metaheuris.ic algorithm called Frilled Lizard Optimization(FLO),which emulates.the unique hunting behavior of frilled lizards.in their natural habitat.FLO draws.its.ins.iration from the s.t-and-wait hunting s.rategy of thes. lizards.The algorithm’s.core principles.are meticulous.y detailed and mathematically s.ructured into two dis.inct phas.s.(i)an exploration phas.,which mimics.the lizard’s.s.dden attack on its.prey,and(ii)an exploitation phas.,which s.mulates.the lizard’s.retreat to the treetops.after feeding.To as.es.
