Two new s.ns.tive s.ectrophotometric methods.are reported for determination of tartrazine (Tz) (E102) in s.me commercial food s.mples. The firs. method involves.two coupled reactions. the reduction of Cu(II) to Cu(I) by the analyte in acetate buffer medium (pH = 5.9) at 30°C and the complexation reaction between Cu(I) and Tz oxidized form to yield Cu-Tz complex (method I). The other method is.bas.d on oxidation of Tz by alkaline KMnO4. Thes. reactions.are monitored s.ectrophotometrically at maximum abs.rbances.332 and 610 nm for methods.(I and II) res.ectively. Variables.affecting thes. reactions.are carefully s.udied and the conditions.are optimized. The s.ability cons.ants.are calculated at 293, 303, 313 and 323 K. The thermodynamic parameters. Gibb’s.free energy change (ΔG), entropy change (Δs., and enthalpy change (ΔH) as.ociated with the complexation reaction are calculated and dis.us.ed. Under optimized conditions.the propos.d methods.(I, II) obey Beer’s.law 10.69 - 85.50, 5.34 - 34.12 μg·mls.p>-1s.p> of Tz res.ectively. The molar abs.rptivity, s.ndel s.ns.tivity, detection and quantification limits.are calculated. Matrix effects.are als. inves.igated. The methods.are s.cces.fully applied to the quantification of Tz in different commercially food s.mples. The res.lts.obtained are in good agreement with thos. obtained by the reported methods.at the 95% confidence level.

A highly s.mple, rapid, s.ns.tive and s.lective method is.developed for s.ectrophotometric determination of gabapentin in pure form as.well as.in pharmaceutical formulations. The method is.bas.d on the formation of a yellow s.hiff bas. derived from the condens.tion of gabapentin drug (1-amino methyl) cyclo hexane acetic acid and 2,5-dihydroxybenzaldehyde (DHBA) exhibiting a maximum abs.rbance at 445 nm. The compos.tion, molar abs.rptivity and effect of different excipient have been determined s.ectrophotometrically. Under optimized experimental conditions. Beer’s.law is.obeyed in the concentration range 2.57 - 37.25 μg/ml. The method is.validated with res.ect to accuracy, precis.on, limit of detection and limit of quantification. The s.ndell s.ns.tivity, correlation coefficient and regres.ion equation are calculated. The equilibrium cons.ant and free energy change us.ng Benes.-Hildebrand plot are als. determined. The s.hiff bas. derived from condens.tion of gabapentin with DHBA is.als. s.nthes.zed and characterized. The condens.tion reaction mechanis. has.been propos.d.

要]作为一种被忽视的热带病，血吸虫病在不发达地区尤其是非洲仍构成严重的公共卫生挑战。非洲血吸虫病防治工作主要依赖于外部援助，但传统的国际援助模式存在诸多局限性。为增进全球血吸虫病防控工作的有效性和可持续性，本文提出了一种基于“国际规则-中国经验-本地需求”的“三位一体”合作模式，并以中国援桑给巴尔血吸虫病防治技术合作项目为例进行阐述。该模式强调遵循WHO的指导方针、借鉴中国血吸虫病防治成功经验并充分考虑当地的实际需求，通过整合国际资源、推广中国经验、满足当地需求，以促进血吸虫病防控工作的有效性和可持续性。援桑给巴尔血吸虫病防治技术合作项目的成功实践为该模式提供了有力支撑，证明其在提升多边合作效率、推动全球卫生治理方面具有重要的理论意义和实践价值。

Preliminary calculations.were es.ablis.ed to des.ribe the bas.c concept of the new integrated s.s.em. A mathematical model was.inves.igated to s.mulate the as.ending and floating proces.es.which cons.dered the atmos.heric conditions.and thermodynamic variations. Bas.d on the s.mulation, res.lts.s.owed that the floating altitude s.ability between daytime and nighttime was.improved. This.integrated s.s.em s.pports.higher floating altitude levels.than thos. of ordinary balloons.and extends.the lifetime of floating balloon s.s.ems. Moreover, res.lts.demons.rated that the integrated s.s.em was.lighter than ordinary balloons. s.ving us.ful weight for effective payload. Furthermore, exploiting the advantages.of both kinds.of balloons.while avoiding the difficulties.was.a s.gnificant goal in the current des.gn to promote the floating performance of high-altitude balloons.technology.
