In this study,Ni catalysts supported on Pr-doped ce O_(2) are studied for the cO_(2) methanation reaction and the effect of Pr doping on the physicochemical properties and the catalytic performance is thoroughly *** is shown,that Pr^(3+)ions can substitute ce^(4+)ones in the support lattice,thereby introducing a high population of oxygen vacancies,which act as active sites for cO_(2) *** doping can also act to reduce the crystallite size of metallic Ni,thus promoting the active metal *** performance evaluation evidences the promoting effect of low Pr loadings(5 at%and 10 at%)towards a higher catalytic activity and lower cO_(2) activation *** the other hand,higher Pr contents negate the positive effects on the catalytic activity by decreasing the oxygen vacancy population,thereby creating a volcano-type trend towards an optimum amount of aliovalent substitution.

在这个全球化的年代,世界不平等是上升了还是下降了的问题是一个热门话题。研究经济不平等的测量的前沿学者发展了各种方法来实证地估计世界居民的福利分配。尽管他们使用了类似的方法,但是并没有形成一致的结论。目前的论文已经形成两种完全相反的观点。SalaiMartin(2002a,b)认为,从二十世纪七十年代末到二十世纪九十年代末,世界不平等在下降是毋庸置疑的。Milanovic(2002a,b,c)并不否认这一点,但是他以经验为依据阐明了国家内部(尤其是城镇和农村之间)不平等趋势的重要性,估计了真实世界的不平等,并且得到了与前者相反的结论。然而,大家(尤其这里所引述的文献)对世界收入分配不平等的测量上是一致的。我们的结果表明,至少对于国际不平等,我们有经验证据证明一般的熵方法测量的不平等的排序发生了变化,并且我们希望这对于世界不平等也是正确的。然而,关于使用哪一种不平等测量方法来估算真实的世界不平等的规范的争论还没有正式开始。

The water absorption kinetics of three cowpea varieties (Asontem, Hewale and Asomdwee) was studied following the phenomenological models derived from Fick’s law of diffusion. Soaking of seeds from each cowpea variety was carried out for 10 h at four temperatures (30°c, 40°c, 50°c and 60°c). The saturation moisture content was higher for Asontem (106.9 g water/1000 g dry weight) and Hewale varieties (108.7 g water/1000 g dry weight) and lower for Asomdwee hybrid (100.7 g water/1000 g dry weight), respectively. The proposed Fick’s law of diffusion satisfactorily described the kinetics of water absorption regardless of the variety and temperature. The estimated values for water diffusion coefficient for Asontem, Hewale and Asomdwee varied from 5.12 × 10-10 m2/s to 6.64 × 10-10 m2/s, 3.96 × 10-10 m2/s to 5.12 × 10-10 m2/s, 4.93 × 10-10 m2/s to 6.08 × 10-10 m2/s, respectively. The strong influence of temperature on the water diffusion coefficient was adequately described by an Arrhenius-type equation with activation energy values for Asontem, Hewale and Asomdwee as 7.27 kJ/mol, 7.26 kJ/mol and 6.26 kJ/mol, respectively.

Peripheral venous catheters (PVc) are widely used in the hospital and seem to be innocent. However, complications can be devastating. We present a case of a fatal septic shock due to vertebral osteomyelitis after PVc-related Staphylococcus aureus bacteremia (SAB). Staphylococcus aureus is a leading cause of bacteraemia in both the community and the hospital with a significantly increased incidence over the last several decades. Intravascular catheters are the most common cause of SAB. Morbidity and mortality are high, even with appropriate therapy. Although complications are known and common, they may be difficult to recognize. Vertebral osteomyelitis is one of these known severe complications.

The IPcc SRES narratives were implemented in IMAGE 2.2 to evaluate thefuture condition of the climate system (including the biosphere). A series of scenario experiments was used to assess possible ranges in emissions and concentrations of greenhouse gases, climate change and impacts. These experiments focussed on the role of the terrestrial carbon cycle. The experiments show that the SRES narratives dominate human emissions and not natural processes. In contrary, atmospheric cO2 concentration strongly differs between the experiments. Atmospheric cO2 concentrations range for A1B from 714 to 1009 ppmv cO2 in 2100. The spread of this range is comparable with the full SRES range as implemented in IMAGE 2.2 (515-895 μmol/mol cO2). The most important negative and positive feedback processes in IMAGE 2.2 on the build-up of cO2 concentrations are cO2 fertilisation and soil respiration respectively. Indirect effects of these processes furtherchange land-use patterns, deforestation rates and alter the natural c fluxes. The cumulative effects of these changes have a pronounced influence on the final cO2 concentrations. Our scenario experiments highlight the importance of a proper parameterisation of feedback processes, c-cycle and land use in determining the future states of the climate system.

关键词： carbon cycle, feedback processes, integrated assessment modeling, land use, SRES scenarios.
