Determination of tryptophan in feedstuffs: Comparison of two methods of hydrolysis prior to HPLC analysis

The tryptophan content of nine samples of commercial feed was determined using two procedures (I and II) differing mainly in the hydrolysis conditions used prior to analysis. With I, hydrolysis was performed with 4 M LiOH in the presence of maltodextrin with 5-methyltryptophan used as internal standard at 110°C for 24 h; with II. oxygen-free 1.3 M Ba(OH)₂ was used at 125°C for 16 h. The two procedures gave identical results for a given sample indicating that the corrections for the incomplete recovery of tryptophan 5-methyltryptophan quantitation were satisfactory.     

Political orientation and modern versus aversive racism: Tests of Dovidio and Gaertner's (1998) integrated model.

According to J. F. Dovidio and S. L. Gaertner's (1998) integrated model of racism, politically liberal European Americans tend to express racism differently than conservative European Americans, with liberals demonstrating aversive racism and conservatives, symbolic or modern racism. In support of the model, in Experiment 1 liberals showed bias in favor of a twice-prosecuted African American relative to a European American in their judgment of double jeopardy, whereas conservatives did the reverse. Experiment 2 replicated these effects while eliminating a confound in the design of Experiment 1. Experiment 3 found evidence for the intrapsychic conflict hypothesized to underlie aversive racism. Specifically, only liberals displayed greater physiological arousal to the touch of an African American versus a European American experimenter.

孔板—均速管组合法测量汽—水两相流双参数

利用孔板与均速管组合在线测量汽—水两相流双参数，解决了稠油热采中同时测量蒸汽流量与干度的难题。其工作程序用Mcs-51单片机汇编语言编制而成，主程序由初始化、数据采集处理，热物理参数生成、汽—水两相流量、干度、质量流量、热量计算以及累计运算等模块组成。通过在现场进行标定；干度用化验CI^-法进行标定，流量用锅炉入口的涡轮流量计标定。经胜利和新疆两油田进行的大量试验可知，该仪表测量水蒸汽流量和干度其均方差皆小于7%，满足了工业应用要求。     

利用双种群遗传算法进行数值试井自动拟合

遗传算法以随机化技术为指导，通过对整个解空间的高效搜索而得到全局最优解，当解空间较大时，常规遗传算法难以同时保证搜索速度和最优解的精度。针对这种缺陷提出了应用双种群遗传算法，即利用具有不同搜索策略的2个种群进行联合搜索，既保证了最优解的精度，又提高了搜索速度，将其应用于数值试井自动拟合解释，比常规遗传算法能节省50％以上的计算时间。     

Mn-containing catalytic materials for the total combustion of toluene: The role of Mn localisation in the structure of LDH precursor

Mg/Mn/Al mixed oxide systems of similar atomic ratios close to 2/0.5/1 were obtained by calcination of Mg,Al layered double hydroxide (LDH) type precursors containing Mn either in the cationic form within the brucite layer or as permanganate anions in the interlayer. The materials were characterised with PXRD, thermal analysis, XPS, ESR, TPR and BET. In mixed oxides derived from interlayer-doped precursor PXRD identified MgO–MnO solid solution and poorly crystalline Al-rich spinel phase, while those obtained from layer-doped LDH contained a better crystalline Mn-rich spinel. Surface of both materials was covered with poorly crystalline and/or amorphous Mn⁴⁺-containing phases. Higher reducibility of this surface coat in calcined layer-doped catalyst, as compared to interlayer-doped one, was attributed to the differences in the nature of underlying crystalline phases, and was considered the chief reason for the higher catalytic activity of this catalyst in the total oxidation of toluene.     

再论异重流和均质流动的一些相似关系

在对上层静止下层流动的异重流和均质明渠流之间相似关系研究的基础上，本文将这一成果推广，给出了上层流动下层静止的异重流和均质明渠流之间的一些相似关系，并将结果应用于二维重叠式排取水口的水深计算，结果与前人的实验一致。考虑到实际的重叠式排取水口都是三维的，所以本文利用前人的实验结果，进一步给出了三维重叠式排取水口高度及水深的计算方法，所得结果揭示了排水口温差水跃的形成机理和形成条件。
