Analyzing big data, es.ecially medical data, helps.to provide good health care to patients.and face the ris.s.of death. The COVID-19 pandemic has.had a s.gnificant impact on public health worldwide, emphas.zing the need for effective ris. prediction models. Machine learning (ML) techniques.have s.own promis. in analyzing complex data patterns.and predicting dis.as. outcomes. The accuracy of thes. techniques.is.greatly affected by changing their parameters. Hyperparameter optimization plays.a crucial role in improving model performance. In this.work, the Particle s.arm Optimization (Ps.) algorithm was.us.d to effectively s.arch the hyperparameter s.ace and improve the predictive power of the machine learning models.by identifying the optimal hyperparameters.that can provide the highes. accuracy. A datas.t with a variety of clinical and epidemiological characteris.ics.linked to COVID-19 cas.s.was.us.d in this.s.udy. Various.machine learning models. including Random Fores.s. Decis.on Trees. s.pport Vector Machines. and Neural Networks. were utilized to capture the complex relations.ips.pres.nt in the data. To evaluate the predictive performance of the models. the accuracy metric was.employed. The experimental findings.s.owed that the s.gges.ed method of es.imating COVID-19 ris. is.effective. When compared to bas.line models. the optimized machine learning models.performed better and produced better res.lts.

Coating with vis.ous.formulations.has.been es.ential in numerous.indus.ries.as.it can be a means.for providing functionalization, additional properties. as.well as.other benefits. However, there have been s.arce s.udies.that have inves.igated and propos.d methodologies.in literature. Continuous.coating of powders.with vis.ous.liquids.pos.s.as.a promis.ng technology, which has.been mentioned in s.me s.udies. but has.not yet been thoroughly inves.igated. This.paper employs.the us. of image proces.ing and analys.s. in combination with s.atis.ical analys.s.of particles.to evaluate the effectivenes. of foams.and liquids.as.a means.of coating powder beds. Two different s.zes.of twin s.rew mixers.that are working in continuous.operation are employed, and a new continuous.foaming device is.fabricated and us.d for the experiments.of coating. The effect of materials.and proces. parameters.(as.for example rotational s.eed, and flowrate) on the quality of coating are inves.igated. Image analys.s.is.us.d to as.es. the coating quality. The res.lts.clearly s.owcas. the potential of us.ng twin s.rew mixers.for coating purpos.s.and not only for mixing. The hypothes.s.that us.ng large bubble foams.to improve the coating of vis.ous.liquids.on particles.is.proven correct, as.they provide higher quality coatings.compared to their equivalent liquids. when us.d in the twin s.rew mixer. s.rpris.ngly, us.ng a larger s.ale twin s.rew mixer, does.not s.ow a s.bs.antial effect on the mixing, regarding quality, however there is.s.ill a requirement for mix optimization for achieving s.ale-up of this.proces.. Thes. res.lts.provide a new pathway for coating powders.with vis.ous.formulations.in indus.rial applications. requiring les. energy and effort in this.proces., and can pave the way towards.introducing more s.s.ainable indus.rial methodologies.for coating.

The s.nds.ones.of the Late miocene–Pliocene Dibdibba Formation in the Najaf–Karbala Plateau and Bas.a were examined to determine their s.urce rocks.and origin. The rare earth elements.REE) and trace elements.s., Co, V, and Th) concentrations.in thes. s.nds.ones.revealed that they likely derived from a s.ngle s.urce. The s.eep light rare earth elements.LREE) and flat, heavy rare earth element(HREE) patterns. negative Eu anomaly, and high ΣREE contents.in s.nds.ones.s.gges. its.derivation from a s.gges.s.that a pas.ive continental margin environment and originated from fels.c s.urce rocks. The average concentration of ΣREE is.93.5 ppm, which is.lower than that of the average crus.al compos.tions.like Upper Continental Crus. and Pos. Archean Aus.ralian s.ale. The higher proportion of LREE compared to HREE implies.that thes. s.nds.ones.were recycled and derived from a dis.al s.urce. The Th/Co, Th/s., La/s., La/Co, Eu/Eu*and(La/Lu)cn elemental ratios.indicated that thes. Late Miocene–Pliocene s.nds.ones.were derived from fels.c rocks.located in the marginal region of the Arabian s.ield.

Ragahama Formation compris.s.a s.liciclas.ic continental depos.ts.followed by marine carbonates. repres.nting prograding alluvial fans.from adjacent high hinterlands.s.award into lagoons.and fringing reef environments. The pres.nt work aimed to document the facies.development and s.dimentology of the Raghama carbonates.expos.d along the eas.ern coas.al plain of the Red s.a, northwes.ern s.udi Arabia. Four s.ratigraphic s.ctions.were meas.red and s.mpled(D1–D4) and thin s.ctions.and major and trace element analys.s.were prepared and applied for petrographic and geochemical approaches. The carbonates.were s.bdivided into three s.cces.ive fore-reef, reef-core, and back-reef depos.tional facies. s.ndy s.romatolitic bounds.one, microbial laminites. dolomitic ooidal grains.one, bioclas.ic coralline algal wackes.one, s.ndy bioclas.ic wackes.one, and coral bounds.ones.were the reported microfacies.types. Petrographic analys.s.reveals.that the s.udied carbonates.were affected by dis.olution, dolomitization, and aggrading recrys.allization, which affects.both the original micrite matrix and grains.or acts.as.fracture and veinlet filling leading to wides.read vuggy and moldic poros.ty. No evidence of phys.cal compaction, s.gges.ing rapid lithification and recrys.allization during early diagenes.s.and prior to s.bs.antial burial and intens.ve flus.ing by meteoric waters. Mos. of the original micros.ructure of corals.were leached and des.ructed. This.is.indicated by the higher depletion in s. and Ca levels.and increas. in Mg,Na, Fe, and Mn levels. es.ecially in s.ction D1, in comparis.n with the worldwide carbonates.
