, 2014 本发明涉及一种以惰性氧化物载体(SiO2、Al2O3、ZrO2、YSZ等)负载的钙钛矿类(ABO3-δ；δ＝0-1)化合物做为活性材料，通过两步热化学循环分解CO2，产生CO的方法。主要步骤为：(1)活性材料首先在高温下放出氧气；(2)含有大量氧空位的活性材料在较低温度下与CO2反应，放出CO。本发明首次利用钙钛矿作为活性材料进行CO2的分解反应，钙钛矿类活性材料与其他活性材料相比，可以在较低温度下放出大量的氧气(1300℃条件下16-25ml/g)，产生可观量的CO(20-30ml/g ...

, 1998 方法：用超微颗粒（８０％＜１μｍ）钙、碳酸钙、脱脂乳粉配制的饲料及基础的低钙饲料分别喂养４组断乳Ｗｉｓｔａｒ大鼠４周，并做３天钙代谢实验。结果：超微颗粒钙组大鼠体重增长率为８０．４％；钙吸收率、储留率及利用率分别为７１．１％、９１．４％和６１．４％；股骨指数为５．８８；股骨钙存留率为４．９７％，与碳酸钙组比较差异显著（Ｐ＜０．０５或Ｐ＜０．０１）。血清钙为２．３９ｍｍｏｌ／Ｌ；血清磷为２．３１ｍｍｏｌ／Ｌ，均在正常范围以内。与脱脂乳粉组比较，超微颗粒钙的利用率达到脱脂乳粉组的７３％以上。结论 ...

A CIÊNCIA É MASCULINA? É, sim senhora!...
Contexto & Educação, 2013 Partindo do princípio de que não somos sociedades machistas por acaso, são analisadas três vertentes que nos constituíram como humanos no mundo ocidental: a grega (os mitos e a Filosofia), a judaica (cosmogonia e a Torá) e a cristã (Apóstolo Paulo e outros doutores da Igreja Cristã).
