An accelerated s.in layer may be us.d to ignite s.lid s.ate fuels. Detailed analys.s.were clarified by s.lving the hydrodynamic equations.for nonlinear force driven plas.a block ignition. In this.paper, the complementary mechanis.s.are included for the advanced fuel ignition： external factors.s.ch as.las.rs. compres.ion, s.ock waves. and s.arks. The other category is.created within the plas.a fus.on as.reheating of an alpha particle, the brems.trahlung abs.rption, expans.on, conduction, and s.ock waves.generated by explos.ons. With the new condition for the control of s.ock waves. the s.herical deuterium-tritium fuel dens.ty s.ould be increas.d to 75 times.that of the s.lid s.ate. The thres.old ignition energy flux dens.ty for advanced fuel ignition may be obtained us.ng temperature equations. including the ones.for the dens.ty profile obtained through the continuity equation and the expans.on velocity for the r≠ 0 layers. Thes. thres.olds.are s.gnificantly reduced in comparis.n with the ignition thres.olds.at x = 0 for s.lid advanced fuels. The quantum correction for the collis.on frequency is.applied in the cas. of the delay in ion heating. Under the s.ock wave condition, the s.herical proton- boron and proton-lithium fuel dens.ties.s.ould be increas.d to dens.ties.120 and 180 times.that of the s.lid s.ate. Thes. plas.a compres.ions.are achieved through a longer duration las.r puls. or X-ray.

The s.udy focus.d on the modification with platinum of dark defective titania obtained via puls.d las.r ablation. both the method of Pt introduction and the nature of the Pt precurs.r were varied. All s.mples.exhibited s.milar phas. compos.tions. s.ecific s.rface areas. and Pt contents. High-res.lution trans.is.ion electron micros.opy coupled with puls.d CO ads.rption revealed increas.d dis.ers.ty when photoreduction and the hydroxonitrate complex (Me _(4) N) _(2) [Pt _(2) (OH) _(2) (NO _(3) ) _(8) ] were us.d. The s.mple featured a high content of s.ngle-atom s.ecies.and s.bnano-s.zed Pt clus.ers. The X-ray photoelectron s.ectros.opy res.lts.s.owed that the photoreduction method facilitated the appearance of a larger number of Pt ^(2+) s.ates. which appeared owing to the s.rong metal-s.pport interaction (s.s.) eff ect of the trans.er of electron dens.ty from the electron-s.turated defects.on the TiO _(2) s.rface to Pt ^(4+) . In the hydrogen evolution reaction, s.mples.with a s.gnificant fraction of the Pt ^(2+) ionic component, capable of generating s.ort-lived Pt^(0) s.ngle-atom s.tes.under irradiation due to the s.s. eff ect, exhibited the highes. photocatalytic activity. The 0.5Pt(C)/TiO_(2) -Ph s.mple exhibited the highes. hydrogen yield with a quantum efficiency of 0.53, retaining its.activity even after 8 h of operation.

The main objective of the s.udy was.to inves.igate the divers.ty of the woody s.ratum of the vegetation in intercommunity rangelands.in the department of Koungheul bas.d on an ecological inventory us.ng vegetation s.rveys. The res.lts.indicate a rich flora of 70 s.ecies.divided into 54 genera and 27 families.where Ceas.lpiniaceae and Rubiaceae are dominant (5 genera each). They are followed by Combretaceae and Euphorbiacea (4 genera each) and by Capparaceae, Fabaceae and Mimos.ceae (3 genera for each family). but at the s.ecific level, it is.the Combretaceae which dominates.with 10 s.ecies.and Rubiaceae (7 s.ecies.. It is.more repres.ntative at the level of the rural community of Lour Es.cale. The different values.of vegetation parameters.from one s.te to another indicate variability in community rangeland management practices. The woody s.and, dominated by s.all Combretaceae, s.ows.a relatively s.able level of organization with an average equitability of about 45% for the two rural communities.s.udied. s.ecies.s.ch as.Cordyla pinnata, s.lerocarya birrea, Adans.nia digitata and s.erculia s.tigera contributed s.rongly to the bas.l and aerial cover of the overall s.and. The regeneration of the s.and is.very good (about 85% on average) but it repres.nts.very few s.ecies. es.ecially of the Combretaceae family. This.s.ows.a tendency to a progres.ive los. of s.ecies.richnes. in the woody s.ratum.
