Tea saponins affect in vitro fermentation and methanogenesis in faunated and defaunated rumen fluid 总被引:4,自引:0,他引:4
INTRODUCTION Livestock is one of the largest sources of meth-ane emission with 80~115 million tons produced peryear, equivalent to 15%~20% of total anthropogenicmethane (IPCC, 2001). The global cattle population isresponsible for 73% of methane emissions of alllivestock, and methane produced during ruminalfermentation represents a loss of 2%~15% of grossenergy intake and may contribute to global warming(Johnson and Johnson, 1995). Many researches hadbeen carried out to find ways to low… 相似文献

过于僵化或过于刚性的教学运作机制是制约高校发展和达到目标的主要障碍,教学运作机制改革本质上是围绕教学(人才培养)进行的整个管理制度的配套改革。无论从学生所学内容和培养方案及素质教育的开展方面,还是从教学管理制度方面来论证,这种改革都具有必要性和紧迫性。教学运作机制的改革应从易到难,围绕探索优秀的教学模式层层推进,并要对改革中可能遇到的主要困难和问题作好充分的思想准备。 相似文献

Objective:To investigate the periodontal status and associated risk factors among women of childbearing age to increase the awareness of oral health.Methods:The study was conducted on childbearing age women in Cixi,a city in Zhejiang Province in the southeast of China.A total of 754 women participated in periodontal examination while receiving prenatal care.Data of the women were collected from the Cixi Family Planning Commission and during an interview.Clinical periodontal indices,such as bleeding on probing(BOP),probing depth(PD),and clinical attachment level(CAL) were measured during the examination.Statistical analysis on subject-based data was performed.Results:The prevalence of periodontal disease among childbearing age women in Cixi was high(84.7%).A significant association was found between the disease and educational level,pregnancy,taking oral contraceptives,stress,alcohol consumption,overweight,dental visit,and teeth brushing(P<0.05).Women who suffered periodontal disease showed deep PD,obvious BOP,and clinical attachment loss.Among this population,pregnancy was closely associated with higher BOP percentage;teeth brushing no more than once per day or brushing for less than 1 min(P<0.001) after adjusting for age and stress.Conclusions:The periodontal status of childbearing age women in Cixi needs to be improved urgently.Attention towards the periodontal health should be warranted,especially for those in special statuses and with poor awareness. 相似文献

鲁迅在他的杂文、书信、序、或后记里,对于他创作时期个人的与国家民族的“郁结”,对于他陷于社会承诺和个人冥思之间焦躁不安的心理状态,有极大幅度的表白。而这种彷徨求索的焦躁不安,包括一种强烈的求死以再生的欲望——形而上的死亡的欲望,很形象化地弥漫在他1924年至1926年间写的散文诗集《野草》和那个时期写的书信之中。论文以鲁迅的《摩罗诗力说》为开端,着重论述他的《野草》和书信中流露的“灵魂的毒气”,“黑暗与虚无”的“绝望”和“‘我的面前又竟至于并没有真的暗夜’的悲哀”那种废然的灵魂的探索。 相似文献
