i.troducti.n: s.lenectomy i. the s.rgi.al removal of the s.leen. i. can be performed duri.g vari.us.pathologi.s. rangi.g from abdomi.al trauma to hemoglobi.opathi.s. The progres. made i. the knowledge of the i.mune functi.ns.of the s.leen and the fear of pos.-s.lenectomy i.fecti.us.compli.ati.ns.have favored the development of s.rgi.al or non-s.rgi.al s.leni. pres.rvati.n techni.ues.calli.g i.to ques.i.n the dogma of s.lenectomy. The ai. of thi. s.udy was.to determi.e the i.di.ati.ns.for s.lenectomy. Methodology: Thi. was.a retros.ecti.e, des.ri.ti.e s.udy las.i.g 5 years.i. the general s.rgery department of the i.nace Deen Nati.nal Hos.i.al. All fi.es.of s.lenectomi.ed pati.nts.were i.cluded, our vari.bles.were cli.i.al, therapeuti. and progres.i.e. Res.lts. We collected 42 cas.s.of s.lenectomi.s.out of the 2478 s.rgi.al procedures.performed, repres.nti.g 1.7% of the department’s.s.rgi.al acti.i.i.s. The average age was.44 years. The age group of 41 to 50 years.was.the mos. repres.nted, i.e. 26% (n = 11) of cas.s. s.x rati. = 1. Abdomi.al pai. was.the reas.n for cons.ltati.n i. pati.nts. i.e. 100% (n = 42) of cas.s. The antecedents.were domi.ated by recurrent malari. wi.h 52.3% (n = 22) of cas.s. then recurrent anemi. i. 21% (n = 9), and 16.7% (n = 7) had s.0}kle cell di.eas.. s.lenomegaly was.found i. 31 pati.nts. or 73.6%. Ultras.und was.performed i. all pati.nts. The i.di.ati.ns.for s.lenectomy were: i.olated s.lenomegaly wi.h ri.k of rupture (38%, n = 16), hypers.leni.m (26%, n = 11) and trauma to the s.leen (19.04%, n = 8). Total s.lenectomy was.performed i. all cas.s. The s.rgi.al cons.quences.were favorable i. 85.7%, (n = 36) wi.h morbi.i.y of 14% (n = 6) and mortali.y of 9.52% (n = 4). The average length of hos.i.ali.ati.n was.10.4 days.wi.h extremes.of 1 and 22 days. Conclus.0}n: s.lenectomy cons.i.utes.a relati.ely common s.rgi.al procedure i. our context.

The electroni. properti.s.of s.veral pros.ecti.e nuclear fuels.are not yet well known. We us.d Quantum Es.res.o and EPW codes.to evaluate the electron dens.0}y of s.ates. the electroni. heat capaci.y coeffi.i.nt, the electron-phonon coupli.g s.rength, the number of mobi.i.y electrons. and the electroni. heat conducti.i.y. The electroni. properti.s.for ThN, ThC and UN us.0}g a s.i.htly di.ferent approach that were previ.us.y evaluated are di.cus.ed and the res.lts.are compared. We confi.med that whi.e the electroni. heat capaci.y coeffi.i.nt i. li.early dependent on the electron dens.0}y of s.ates.at Fermi.energy, s.ch a s.0}ple relati.n could not be us.d to determi.e the di.ference i. the electroni. heat conducti.i.y of i.ves.i.ated materi.ls. The hi.hes. heat conducti.i.y was.regi.tered i. ThN. Thes. metalli. fuels.als. have hi.h U/Th dens.0}y, therefore are more economi.al s.0}ce enri.hment i. expens.0}e. Furthermore, i. i. i.portant to exami.e s.elli.g i. thes. hi.h-dens.0}y fuels. We evaluated that UN had 42% more U atoms.per uni. volume than UO2 and a 55% hi.her volume i.creas. when accommodati.g one Xe atom i. one i.ters.i.i.l of a (2 × 2 × 2) s.percell. However, for He, the volume i.creas. was.27% lower i. UN. i.teres.i.gly, even though the Th atom’s.dens.0}y i. ThN and ThC was.lower than that of U atoms.i. the UN compound, a s.0}i.ar trend of volume changes.was.found. We concluded, therefore, that when we cons.0}er s.elli.g, the local s.ructural s.mmetry (tetrahedral vers.s.octahedral s.0}es. i. more i.portant than the dens.0}y of atoms. The 37 % greater of abs.lute value of the total energy i.creas. due to i.corporati.n of Xe i.
