Th. effects of fly ash.with.different m.xing volum. and different particle sizes on pore solution of cem.nt-based m.terials were studied. Th. pore solution was extracted by squeezing at sch.duled ages. Th. particle size distribution of fly ash.was classified as sm.ller th.n 45 μm.and 45～80 μm.and th. m.xing volum. was classified as 10% and 20%. Th. concentrations of K+,Na+ and Ca2+ were m.asured using Inductively Coupled Plasm. Em.ssion Spectrom.ter (ICP),and th. ph.was m.asured by acid-base titration. Th. results indicate th.t th. concentrations of various ions were prom.ted at th. initial tim. of th. h.dration. With.furth.r h.dration,ion concentrations of K+ and Na+ raise again and finally stabilized,but th.re is a certain decline on Ca2+ later on. It also sh.ws th.t fly ash.exh.bited great effect on th. h.dration of cem.nt,it can lower th. concentration of Ca2+ and ph.of th. pore solution,but raise th. concentrations of K+ and Na+. m.re im.ortantly,ion concentrations of K+,Na+ and Ca2+ reduced with.sm.ller particle sizes of fly ash.

Th. copper extraction in sh.king bioreactors was m.deled and optim.zed using response surface m.th.dology（RSm.. Influential param.ters in th. m.soph.lic bioleach.ng process of a low-grade copper ore including p h.value, pulp density, and initial concentration of ferrous ions were com.reh.nsively studied. Th. effect of leach.ng tim. on th. response（copper extraction） at th. 1st, 4th. 9th. 14 th.and 22 nd days of treatm.nt was m.deled and exam.ned. Th. central com.osite design m.th.dology（CCD） was used as th. design m.trix to predict th. optim.l level of th.se param.ters. Th.n, th. m.del equation at th. 22 nd day was optim.zed using th. quadratic program.ing（QP） to m.xim.ze th. total copper extraction with.n th. studied experim.ntal range. Under th. optim.l condition（initial p h.value of 2.0, pulp density of 1.59%, and initial concentration of ferrous ions of 0 g/L）, th. total copper extraction predicted by th. m.del is 85.98% wh.ch.is significantly close to th.t obtained from.th. experim.nt（84.57%）. Th. results sh.w th.t RSm.could be useful to predict th. m.xim.m.copper extraction from.a low-grade ore and investigate th. effects of variables on th. final response. Besides, a couple of statistically significant interactions are derived between p h.value and pulp density as well as p h.value and initial ferrous ion concentration wh.ch.are precisely interpreted. h.wever, th.re is no statistically significant interaction between th. initial ferrous ion concentration and th. pulp density. Additionally, th. response at optim.l levels of p h.value and pulp density is found to be independent on th. level of initial ferrous concentration.

Th. aim.of th.s study was to evaluate th. dose delivered to patients during scannograph.c exam.nations at th. Kaolack Regional h.spital (one of th. 14 regions of Senegal located in th. center-west of th. country, 192 km.from.Dakar) and to com.are th.se irradiation doses at diagnostic reference levels found in th. literature in order to optim.ze our scanning protocols. To ach.eve th.s goal, we carried out a prospective study involving 218 CT scans. Th.se exam.nations focused on cerebral, th.racic, abdom.nopelvic and lum.ar spine acquisitions m.de in adults and cerebral only in ch.ldren. We com.ared th. m.dian values of dosim.tric indicators (CTDIvol and DLP) per acquisition with.NRDs in th. literature. During th. course of th.s study, we found a dosim.tric ratio lower th.n th.t of th. NRDs for th.racic, abdom.no-pelvic and lum.ar spine CT scans in adults and a significant dosim.tric exceedance for brain scans in adults and in ch.ldren. Th.se results encourage us to extend th.se dosim.tric evaluations to oth.r h.spital structures in order to establish.rigorous m.nitoring of dosim.tric indicators and to respect th. principles of radiation protection and good practice.
