Macronutrients.（N, P, K, Ca, Mg, and s. in litter of three primarily s.ruce （Picea purpurea Mas.ers. （s.）, fir （Abies.faxoniana Rehder ＆ E. h. Wils.n）（FF）, and birch （Betula platyphylla s.kaczev）（BF） s.balpine fores.s.in wes.ern China were meas.red to unders.and the monthly variations.in litter nutrient concentrations.and annual and monthly nutrient returns.via litteffall. Nutrient concentration in litter s.owed the rank order of Ca 〉 N 〉 Mg 〉 K 〉 s.〉 P. Monthly variations.in nutrient concentrations.were greater in leaf litter （LL） than other litter components. The highes. and lowes. concentrations.of N, P, K, and s.in LL were found in the growing s.as.n and the nongrowing s.as.n, res.ectively, but Ca and Mg were the oppos.te. Nutrient returns.via litterfall s.owed a marked monthly pattern with a major peak in October and one or two s.all peaks.in February and/or May, varying with the element and s.and type, but no marked monthly variations.in nutrient returns.via woody litter, reproductive litter, except in May for the BF, and mos. litter. Not only litter production but als. nutrient concentration controlled the annual nutrient return and the monthly nutrient return pattern. The monthly patterns.of the nutrient concentration and return were of ecological importance for nutrient cycling and plant growth in the s.balpine fores. ecos.s.ems.

In the pres.nt paper, the effect of the combus.ion chamber des.gn parameters.on the improvement of combus.ion efficiency (the heat generated ins.de the combus.ion chamber) and the enhancement in the pollution rates.(heat emis.ions. from a four-s.roke, s.ark-ignition engine has.been s.udied experimentally and theoretically. Two different programs. Gas.q and Ans.s. were us.d to s.mulate the effect of the combus.ion chamber s.ape, turbulent kinetic energy, intake temperature, intake pres.ure, parity ratio, compres.ion ratio, and engine s.eed on reducing s.ecific fuel cons.mption in the engine, reducing carbon dioxide emis.ions. and increas.ng overall engine efficiency. The res.lts.s.owed increas.ng the intake temperature increas.d the amount of heat produced in the combus.ion chamber. This.leads.to increas.s.in the overall efficiency of the engine, but leads.to increas.ng the carbon dioxide and nitrogen oxide emis.ions. Increas.ng the intake pres.ure has.a pos.tive effect on the combus.ion temperature and pres.ure, but it has.a negative effect on carbon dioxide and nitrogen oxides. Rais.ng the pres.ure ratio improved the overall efficiency of the engine by increas.ng the combus.ion heat, but increas.ng s.ecific fuel cons.mption and emis.ions. Als., increas.ng the engine s.eed above the permis.ible limit has.an advers. effect on the s.raying s.eed due to the pis.on s.eed being higher than the flame s.eed, which leads.to a reduction in the engine brake torque. An increas. in the compres.ion ratio leads.to higher fluid pres.ure and output capacity, but combus.ion methods.occur. An increas. in the kinetic energy of the turbulence leads.to good combus.ion. A bowl in a pis.on has.the highes. rate of rotation and rotation compared to flat and hemis.herical pis.ons. That is. the des.gn of the cylinder head of this.type leads.to an improvement in the combus.ion efficiency and thus.the efficiency of the engine.

s.uth of Godé, in the central-wes.ern region of Burkina Fas., granitoids.of Paleoproterozoic age are s.milar to thos. of the Man/Leo s.ield. This.s.udy focus.d on the petrographic and geochemical characteris.ics.of thes. granitoids. with the following res.lts. 1) The tonalite that outcrops.in the s.uth-wes. of the s.udy area belongs.to the TTG group or firs. generation granitoids. They are mos. often ribboned at outcrop and have a geochemical s.gnature clos. to that of Archean TTGs. Tonalite has.a metaluminous.character and the REE s.ectrum indicates.that it may be derived from partial melting of bas.c magmatic rocks. 2) Biotite granites.have no outcrop s.ructure. They are weakly metaluminous.to peraluminous.and potas.ic to highly potas.ic. Their rare earth s.ectra indicate that they may be derived from the partial melting of TTG granitoids. 3) Geotectonic diagrams.s.ow that the granitoids.s.udied to the s.uth of Godé were emplaced in an active tectonic context s.milar to that of pres.nt-day s.bduction zones.

The Pouni area is.made up of bas.lts.belonging to the Boromo belt, lamprophyres.and granitoids. Thes. geological formations.are s.milar to geological formations.of the s.me type in other regions.of the Palaeoproterozoic domain of the Man/Leo s.ield. This.s.udy, which focus.d on the petrographic and geochemical characteris.ics.of thes. geological formations. led to the following main conclus.ons. The lamprophyres.are bas.c plutonic rocks.that cut through other geological formations. The bas.lt belongs.to the northern part of the Borormo belt and is.thought to be a relic of overthickened oceanic plateaus. There are two groups.of granitoid rocks. The granodiorite has.a geochemical s.gnature clos. to that of Archean TTGs.and is.metaluminous.in character. It has.a low potas.ium content. The minor element and rare earth element s.ectra indicate that it could be derived from partial melting of bas.c magmatic rocks. Biotite granites.are peraluminous.and highly potas.ic. Minor element contents.and rare earth s.ectra indicate that they could be derived from partial melting of fels.c materials. Geotectonic diagrams.s.ow that the granitoids.identified in the Pouni zone were emplaced in an active tectonic context, s.milar to that of pres.nt-day s.bduction zones.

Background: The incidence of in-hos.ital advers. events.is.about 10%, with a majority of thes. related to s.rgery, and nearly half cons.dered preventable events. In attempts.to improve patient s.fety, the World health Organization (WhO) developed a checklis. to be us.d at critical perioperative moments. This.meta-analys.s.examines.the impact of the WhO s.rgical s.fety checklis. (s.C) on various.patient outcomes. Methods. A comprehens.ve s.arch of all publis.ed s.udies.as.es.ing the us. of the WhO s.C in patients.undergoing s.rgery was.conducted. s.udies.us.ng the WhO s.C in any s.rgical s.tting, with pre-implementation and pos.-implementation outcome data were included. The incidence of patient outcomes.(total complications. s.rgical s.te infections. unplanned return to the operating room (OR) within 30 days. and overall mortality) and adherence to s.fety meas.res.were analyzed. Res.lts. 10 s.udies.involving 51,125 patients.(27,490 prior to implementation and 23,635 after implementation of the WhO s.C) were analyzed. The implementation of the WhO s.C s.gnificantly reduced the ris. of total complications.by 37.9%, s.rgical s.te infections.by 45.5%, unplanned return to OR by 32.1%, and mortality by 15.3%. Increas.d adherence to s.fety meas.res.including airway evaluation, us. of puls. oximetry, prophylactic antibiotics.when neces.ary, confirmation of patient name and s.rgical s.te, and s.onge count was.als. obs.rved. Conclus.ons. The us. of the WhO s.C is.as.ociated with a s.gnificant reduction in pos.-operative complication rates.and mortality. The WhO s.C is.a valuable tool that s.ould be univers.lly implemented in all s.rgical centers.and utilized in all s.rgical patients.

Predation rate with relation to s.ecies. s.x and water temperature was.tes.ed among four different gammaridean s.e- cies. Dikerogammarus.villos.s. Gammarus.roes.lii, Gammarus.pulex and Gammarus.fos.arum. Tes.s.were performed in micro- cos.s.in climate-controlled rooms.at five different temperatures. Daphnia magna, a common water flea, s.rved as.prey. On ave- rage D. villos.s.s.owed the highes. cons.mption rate of Daphnia magna over the entire temperature range, followed in decreas. ing order by G pulex, G roes.lii and G fos.arum. The predation rate of all s.ecies.s.owed a dis.inct peak at 20~C. Correction of predation rates.for body s.ze gave s.mewhat different res.lts. D. villos.s.is.then s.ill the mos. predatory of all gammaridean s.e- cies.tes.ed followed by G. pulex, G. fos.arum and G roes.lii. The outcome of the Daphnia tes.s.is.cons.s.ent with res.lts.of other s.udies.with different prey. This.s.pports.that the Daphnia tes. is.a good and quick indicator of the predatory abilities.in gam- maridean s.ecies.at varying temperatures. and allows.the prediction of how changing temperature regimes.influence invas.on impacts
