Presently the iron and steel makers are compelled to incorporate rational initiatives to reduce its processing CO_2 total *** the medium and long term,the injection of small particles of biochar through the tuyerees in blast furnaces,here called Bio-PCI,offers attractive features from the environmental and metallurgical point of view,as it is a renewable carbon neutral reductant and presents lesser impurities than ***,its utilization in iron plants is been hindered by the traditional large availability of relatively economical coal and *** the cost of the principal processing inputs increases(coal,coke and iron ore) the gap between fossil and renewable reductants *** this sense,our contribution aims to complement the metallurgical inquiry of technical feasibility with a strategic identification of the areas with best prospects to benefits from the incorporation of Bio-PCI:where can it flourish?.Our analysis leads to indicate that emerging countries in specific,China,Brazil and India,are in a prime position to incorporate the Bio-PCI as they simultaneously comply with a growing iron industry based on blast furnaces,and possess an important potential for energy generation from forestry residues.

背景手术中知晓是一种不常见的临床现象，仅通过一项研究的病例数量不足以证明和评估其危险因素、发生原西及后遗症。对已发表在科学期刊上的大量病例报告进行综合分析可有效表明术中知晓的状况。方法通过检索国家图书馆医学PubMed数据库，检索词为“知晓”和“麻醉”，检索起止时间为1950年至2005年8月，同时手工检索了上述报告及其他与知晓相关的参考文献。为进行比较，本文设置了2个外科对照组：Sebel等研究中的无知晓患者和1996年国家门诊外科调查中接受全身麻醉的患者，同时采用了全国卫生统计中心的数据对体重和体重指数进行比较。结果271例出现手术中知晓的患者与19504例无知晓患者进行比较，发现知晓患者中大多为女性（P〈0．05）、青年（P〈0．001），手术种类为心脏或产科手术（P〈0．0001）。麻醉恢复室中报告的知晓发生仅占总数的35％。知晓患者使用的麻醉药剂量较小（P〈0．0001），手术中常出现发作性心跳加速及血压升高（P〈0．0001），手术后主诉知晓（52％，P〈0．0001）、睡眠障碍、对未来麻醉的恐惧感及手术中制动、无助及虚弱感、听到噪音和语音等有关（P〈0．041—0．0003）。22％的患者出现迟发型精神症状。结论本综述提示，麻醉过浅和既往知晓史是发生手术中知晓的危险因素，氧化亚氮或肥胖都不会增加其发生率。其中麻醉过浅是最常见的原因。某些预防性操作或许可以减少其发生。

童年肥胖是一个越来越严重的问题,可能会成为其成年肥胖的主要原因。婴儿期体增重与晚年过度肥胖相关。共轭亚油酸(CLA)能减少动物模型和人体的脂肪增加及体脂堆积,但是CLA对婴儿和仔猪模型的影响尚未测定。试验旨在测定采食添加CLA的低脂乳或高脂乳的仔猪体组成和脂质代谢调控。试验采用2×2因子设计,24头仔猪分别饲喂:①低脂(3%)饲粮;②高脂(25%)饲粮;③低脂(3%)饲粮+1%共轭亚油酸;④高脂(25%)饲粮+1%共轭亚油酸,试验期16～17d。尽管低脂饲粮组仔猪耗料量较高,但是仔猪间体增重差异不显著。饲养期间,与低脂饲粮组仔猪相比,高脂饲粮组仔猪的体脂肪贮存量提高50%;CLA减少体脂堆积,且与饲粮脂肪水平无关。CLA添加组,脂肪组织中乙酰CoA羧化酶-α和脂蛋白脂酶的表达显著降低。总之,CLA减少体脂堆积,对日增重没有影响。结果显示,脂肪酸吸收与合成受脂肪组织限制,同时肝脏或肌肉中脂肪酸氧化作用没有变化,进而减少体脂堆积。
