Lao.7Sr0.3Mnl_xNi.O3 （x = 0, 0.025, 0.050 and 0.075） cerami.s were prepared by the conventi.nal soli.-state reacti.n method. The parti.l substi.uti.n of Mn by Ni.＋ leads to a decrease i. cell volume as well as a structural transi.i.n from the rhombohedral to the orthorhombi. structure. Ni.＋ dopi.g i.creases the electri.al resi.ti.i.y, decreases the semi.onductor-metal transi.i.n temperature （Tms） and relati.ely enhances the room temperature magnetoresi.tance （MR）, especi.lly i. x = 0.025 and around Ti.s.

Ti.ani.m alloys are extensi.ely used i. power, chemi.al and petroleum i.dustri.s as constructi.nal materi.ls for vessels and heat transfer tubes. Moreover they are candi.ate materi.ls for nuclear waste di.posal. These alloys have superi.r resi.tance to locali.ed forms of corrosi.n compared to stai.less steels and Ni.base alloys. However, thi. resi.tance i. not as remarkable i. crevi.e corrosi.n condi.i.ns i. some aggressi.e medi.. electrochemi.al corrosi.n tests were conducted on two ASTM Ti.grades na.ely, Ti.2 and Ti.12 i. extremely low pH aci.i. envi.onment. Results i.di.ated that Ti.2 has less resi.tance to both general and crevi.e corrosi.n attack than Ti.12. Both alloys possess better resi.tance to general corrosi.n than to crevi.e corrosi.n. Also, results showed that the molybdate addi.i.n i.proves remarkably the resi.tance of Ti.2 to both types of attack. The i.crease of molybdate i.ns concentrati.n from 0.03 mol/L to 0.15 mol/L made Ti.2 to be as resi.tant as, or somewhat hi.her than, Ti.12. The elecrochemi.al fi.di.gs were further supplemented by opti.al exami.ati.n of the corroded surface.

采用KOH对橄榄渣进行活化得到活性炭。设计2~3正交试验来优化制备工艺条件,水平和因子包括活化温度(600,900℃)、活化时间(1,3 h)和浸渍比(1∶2,1∶4)。活性炭的比表面积作为优化的评价指标。通过氮吸附仪、红外光谱仪和扫描电镜等手段对活性炭的表面化学和孔结构进行表征。结果表明,所有因子及其交互水平都非常显著(p<0.05)。活性炭的比表面积和制备条件的相关系数为99.2%。在最条件下制备的活性炭,比表面积为672 m^2/g、平均孔径为2.05 nm,微孔和介孔率分别为81.36%和18.37%。

Purpose: The ai. i. to show epi.emi.logi.al, cli.i.al and eti.logi.al characteri.ti.s of palpebral wounds. Methodology: Thi. was a retrospecti.e study focusi.g on pati.nts wi.h an eyeli. wound, over a 10-year peri.d from 2012 to 2021. We collected and analyzed the data usi.g Excel. Results: The frequency of eyeli. wounds was 0.1%. The average age of our pati.nts was 19.38 years wi.h a range of 1 and 62 years. The sex rati. was 3.7. Ei.hty-one percent of pati.nts li.ed i. Dakar. Fi.ty-seven percent (57%) of pati.nts consulted less than 24 hours after the trauma and 7% of pati.nts on D1. The ci.cumstances were brawls (11%), domesti. acci.ents (9%), road acci.ents (6%), and work acci.ents (6%). We noted 1 case of dog bi.e. Thi.teen pati.nts presented wi.h post-traumati. decreased vi.ual acui.y. i.volvement of the i.olated upper eyeli. was noted i. 40% of cases and both eyeli.s i. 15% of cases. i.volvement of the lacri.al ducts was noted i. 17% of cases, and that of the free edge i. 21% of cases. Eyeli. wounds were associ.ted wi.h eyeball damage i. 21% of cases. Vari.us associ.ted lesi.ns were observed. Ni.ety-one percent of pati.nts recei.ed surgi.al treatment. Three cases of superi.fecti.ns, 1 case of conjuncti.al granuloma and 1 case of phthysi. of the eyeball wi.h postoperati.e reti.al detachment were noted. Conclusi.n: Eyeli. sores are relati.ely common i. our context. They requi.e rapi. surgi.al treatment i. order to preserve the functi.nal and aestheti. prognosi.. .

Organi. mi.roporous materi.ls based on spi.oketal and spi.othi.ketal polymers were synthesi.ed through 1,3- di.xol-formi.g polymeri.ati.n reacti.n between pentaerythri.ol or pentaerythri.ol tetrathi.l and di.ferent types of cyclohexa- 1,4-di.ne deri.ati.es. The structure of the prepared polymers was confi.med by NMR spectroscopy and molecular mass measurements. Ni.rogen adsorpti.n/desorpti.n i.otherms of the prepared polymers show a large amount of ni.rogen adsorbed at low relati.e pressure i.di.ati.g mi.roporosi.y. These polymers have Brunauer Emmi.t and Teller （BET） surface areas i. the range from 492 （m^2g^-1） to 685 （m^2 g^-1）. The prepared polymers were found to be useful for pervaporati.n separati.n of methanol-toluene mi.ture wi.h a separati.n factor up to 12.5 and fluxes, varyi.g between 6.7×10-3 kg/（m^2 h） and 13.4 × 10^-3 kg/（m^2 h）.
