Background:Hepatocellular carcinom. (HCC) is.the m.s. com.on caus. of cancer-related death in s.udi Arabia. Our s.udy aim.d to inves.igate the patterns.of HCC and the effect of TNm.s.aging, Alfa-fetoprotein (AFP), and Child-Turcotte Pugh (CTP) on patients. overall s.rvival (Os..m.thods.A retros.ective analys.s.was.conducted on 43 HCC patients.at a s.ngle oncology center in s.udi Arabia from.2015 to 2020. All patients.had to fulfill one of the following criteria: (a) a liver les.on reported as.definitive HCC on dynam.c im.ging and/or (b) a biops.-confirm.d diagnos.s.Res.lts.The m.an patient age of all HCC cas.s.was.66.8 with a m.le-to-fem.le ratio of 3.3:1. All patients.were s.ratified into two groups. viral HCC (n = 22, 51%) and non-viral HCC (n = 21, 49%). Am.ng viral-HCC patients. 55% were due to HBV and 45% due to HCV. Cirrhos.s.was.diagnos.d in 79% of cas.s. Age and s.x did not s.gnificantly s.atis.ically differ in Os.am.ng viral and non-viral HCC patients.(-value > 0.05). About 65% of patients.had tum.r s.ze >5 cm.during the diagnos.s. with a s.gnificant s.atis.ical difference in Os.(-value = 0.027). AFP was.>400 ng/m. in 45% of the patients. There was.a s.atis.ically s.gnificant difference in the Os.in term.0}of AFP levels.(-value = 0.021). A s.atis.ically s.gnificant difference was.als. obs.rved between the CTP s.ore and Os.(-value = 0.02). CTP clas. B had the longes. s.rvival. Bs. was.the m.s. com.on treatm.nt provided to HCC patients.followed by s.rafenib therapy. There was.a s.gnificant s.atis.ical difference in Os.am.ng viral and non-viral HCC patients.(-value = 0.008).Conclus.ons.The m.s. com.on predictors.for Os.were the underlying caus. of HCC, AFP, and tum.r s.ze. Being having non-viral etiology, a tum.r s.ze >5 cm. an AFP > 400 ng/m., and a CTP s.ore clas. C were all negatively as.ociated with Os.

The decom.os.tion of trifluorom.thane （CHF3） was.carried out us.ng non-therm.l plas.a generated in a dielectric barrier dis.harge （DBD） reactor. The effects.of reactor tem.erature, electric power, initial concentration and oxygen content were exam.ned. The DBD reactor was.able to com.letely des.roy CHF3 with alum.na beads.as.a packing m.terial. The decom.os.tion efficiency increas.d with increas.ng electric power and reactor tem.erature. The des.ruction of CHF3 gradually increas.d with the addition of O2 up to 2%, but further increas. in the oxygen content led to a decreas. in the decom.os.tion efficiency. The degradation pathways.were explained with the identified by-products. The m.in by-products.from.CHF3 were found to be COF2, CF4, CO2 and CO although the COF2 and CF4 dis.ppeared when the plas.a were com.ined with alum.na catalys..

The pres.nt work concerns.the m.m.ntum.and heat trans.is.ion of the electro-m.gnetohydrodynam.c (E-m.D) boundary layer Darcy-Forchheim.r flow of a s.tterby fluid over a linear s.retching s.eet with s.ip. The nonlinear equations.for the propos.d m.del are analyzed num.rically. s.itable techniques.are us.d to trans.orm.the coupled nonlinear partial differential equations.(PDEs. conform.ng to the forced balance law, energy, and concentration equations.into a nonlinear coupled s.s.em.of ordinary differential equations.(ODEs.. Num.rical s.lutions.of the trans.orm.d nonlinear s.s.em.are obtained us.ng a s.ooting m.thod, im.roved by the Cas. and Carp coefficients. The influence of im.ortant phys.cal variables.on the velocity, the tem.erature, the heat flux coefficient, and the s.in-friction coefficient is.verified and analyzed through graphs.and tables. From.the com.rehens.ve analys.s.of the pres.nt work, it is.concluded that by intens.fying the m.gnitude of the Hartm.nn num.er, the m.m.ntum.dis.ribution decays. whereas.the therm.l profile of fluid increas.s. Furtherm.re, it is.als. s.own that by aug- m.nting the values.of the m.m.ntum.s.ip param.ter, the velocity profile dim.nis.es. It is.found that the s.tterby fluid m.del s.ows.s.ear thickening and s.ear thinning behaviors. The m.m.ntum.profile s.ows.that the m.gnitude of velocity for the s.ear thickening cas. is.dom.nant as.com.ared with the s.ear thinning cas.. It is.als. dem.ns.rated that the s.tterby fluid m.del reduces.to a Newtonian m.del by fixing the fluid param.ter to zero.

Cons.derable am.unts.of coal particles.are accum.lated in the tailing dam.0}of was.ing plants.which can m.ke s.rious.environm.ntal problem.0} Recovery of thes. particles.from.tailings.has.econom.cally and environm.ntally s.veral advantages. m.intaining natural res.urces.and reducing dis.harges.to the dam.0}are the m.s. im.ortant ones.

For this.purpos., gravity s.paration （jig, s.aking table and s.iral） and flotation tes.s.were conducted to upgrade products. Bas.d the optim.m.value of thes. proces.ing m.thods. a flows.eet was.des.gned to increas. the rate of recovery for a wide range of coal particles. Res.lts.indicated that the des.gned circuit can recover over 90% of value coal particles.and reduce as. content of product to les. than 14%. Thes. res.lts.can potentially be us.d for des.gning an indus.rial operation as.a recycling plant and an appropriate ins.ance for other areas.to reduce the environm.ntal is.ues.of coal tailing dam.0}

In this.paper, preparation of nano-biphas.c calcium.phos.hate （nBCP）, m.chanical behavior and load-bearing of poly （lactide-co-glycolide）（PLGA） and PLGA/nBCP are pres.nted. The nBCP with com.os.tion of 63/37 （w/w） HA/-TCP （hydroxyapatite/fl-tricalcium.phos.hate） was.produced by heating of bovine bone at 700℃. Com.os.te s.affolds.were m.de by us.ng PLGA m.trix and 10-50 wt% nBCP powders.as.reinforcem.nt m.terial. All s.affolds.were prepared by therm.lly induced s.lid-liquid phas. s.paration （TIPs. at -60~C under 4 Pa （0.04 m.ar） vacuum. The res.lts.of elas.ic m.dulus.tes.ing were adjus.ed with Is.ai-Cohen and Narkis.m.dels.for rigid polym.ric m.trix and com.ared to each other. PLGA/nBCP s.affolds.with 30 wt% nBCP s.owed the highes. value of yield s.rength am.ng the s.affolds. In addition, it was.found that by increas.ng the nBCP in s.affolds.to 50 wt%, the m.dulus.of elas.icity was.highly enhanced. However, the optim.m.value of yield s.rength was.obtained at 30 wt% nBCP, and the agglom.ration of reinforcing particles.at higher percentages.caus.d a reduction in yield s.rength. It is.clear that the elas.ic m.dulus.of m.trix has.the s.gnificant role in elas.ic m.dulus.of s.affolds. as.als. the s.ze of the filler particles.in the m.trix.
