Standardized ileal digestibility coefficients(SIdC)of nitrogen(N)and amino acids(AA)in two protein sources(soybean meal[SBM]and canola meal[CM])were investigated at six broiler ages(d 7,14,21,28,35,and 42).Two assay diets were formulated to contain either SBM(413 g/kg)or CM(553 g/kg)as the sole dietary AA *** dioxide(5 g/kg)was added as an indigestible marker.A total of 696 male broilers at 1 d old were allotted to 12 replicate cages per age *** assay diet was offered to birds for 4 d prior to the ileal digesta collection on d 7(14 birds/cage),14(12 birds/cage),21(10 birds/cage),28(8 birds/cage),35(8 birds/cage)and 42(6 birds/cage),*** apparent digestibility coefficients were standardized using age-specific basal endogenous AA *** the SBM group,though the SIdC of N tended to be influenced(quadratic;P=0.075)by age,no linear or quadratic response of age effect was observed on the average SIdC of indispensable(IAA)and total AA(TAA).An age effect(quadratic;Pd on the average SIdC of dispensable AA(dAA)in SBM with the highest value recorded at d 7,followed by a decrease from d 14 to 28,which increased beyond d *** SIdC of some individual AA(Arg,Thr,Trp,Cys,Pro)were affected(Pdratic manner by *** the CM,the SIdC of N,average SIdC of IAA,dAA and TAA were influenced(quadratic;PdC of N and average SIdC of dAA and TAA were higher from d 7 to 14,declined at d 21,and then increased beyond d *** average SIdC of IAA was low between d 7 and 28 and increased *** SIdC of individual AA were affected(linear or quadratic;Pdifferent magnitudes by *** age influence on the SIdC AA was variable,depending on the protein source and *** results demonstrate that age-specific SIdC AA data might need consideration in broiler feed formulations.

克尔凯郭尔在假名作品《恐惧与战栗》当中描述过“信仰”的“双重运动”,《再现》当中描述过对“再现”的“超越”,它们与德里达所说的“对于不可能的事情的经验”之间有着惊人的对应。因此在主线上,德里达提出的对于不可能的事情的激情与上述两部假名作品当中所提出的“宗教”范畴彼此呼应。一种“不可能性的公理”构成了德里达所说的“没有宗教的宗教”,而不是简单的宗教;构成了某种“宗教的再现”。于是,德里达和克尔凯郭尔的假名作者们拉近了宗教和解构之间的距离。

青藏高原雨季时长及雨季降水量的长尺度定量重建,是揭示高原西风、季风时空演变规律及其生态环境效应的关键,其中准确判断高原雨季的起止时间是研究难点.本文通过寻找降水拐点的方法确定了高原不同地点的雨季起、止时间,并计算了雨季时长和雨季降水量,建立了表土孢粉组合与雨季起止时间、雨季时长和雨季降水量的转换函数,重建了具有年纹层沉积特征的高原北部库赛湖区和中部江错湖区过去2000年来的雨季起止时间、雨季时长和雨季降水量变化.结果表明,过去2000以来,库赛湖区雨季降水序列记录了5次高降水时段:Ad580~680、Ad1000~1100、Ad1200~1450、Ad1550~1780、Ad1920至今,其普遍对应雨季天数长的时段;江错湖区雨季降水序列记录了4次高降水时段:Ad80~500、Ad800~950、Ad1250~1450、Ad1780至今,其与雨季天数长的时段在Ad1000以前对应良好,在Ad1000后关系不明确.在空间上,高原雨季降水呈现出“南北同湿”、“南北同旱”、“南湿北旱”和“南旱北湿”四种模式,其中“南北同湿”可能与异常强盛的夏季风有关,“南北同旱”与弱西风和弱季风有关,“南湿北旱”与强季风和弱西风有关,“南旱北湿”与弱季风和强西风有关.本文从雨季降水的角度揭示了高原2000年来雨季起止时间、雨季时长及雨季降水量的时空演变模式,为进一步认识西风、季风耦合作用提供了自然背景的支持.

在柏拉图的对话《菲德洛斯》里,苏格拉底向年青的菲德洛斯讲述了关于埃及神宙斯——人类的一个大恩人——的一则寓言。宙斯是一位雄心勃勃的发明家,他为人类发明了算术、几何、天文学、西洋跳棋、骰子、以及字母。在这个神话中埃及国王是另外一个名叫萨默思的神。宙斯带着自己的发明到埃及国王那里,向他讲述了这些发明的用途和价值。谈到字母时,宙斯说:“这一发明……会使埃及人交得更聪明,并能增强他们的记忆力。因为我发现:它是一剂改善人类记忆和智慧的特效药。”但是埃及国王却回答说写作将恰恰对人类起到相反的作用,“这一发明将使那些学会使用它的人患健忘症,因为他们再也用不着锻炼自己的记忆力了……”
