A Dissolution of Borderlines in Toni Morrison＇s God Help the Child

The paper focuses on Toni Morrison＇s latest novel God Help the Child （2015）. By presenting a skillful though somewhat perverse merger of binary oppositions at different levels （racial, social, moral, and psychological）, the writer makes borderlines of all sorts appear artificial and therefore invalidates them. Thus, childhood merges with adulthood through sexual traumas that live on; touch with no touch as the evil touch of a parent equals an abhorrence of touching the child Other; truth with a lie as it proves as destructive as lying in good faith; passing blackness with blue blackness as the former conceives the latter; and appearances with reality in the ironic title of the book, where it is both the mother and the child that in fact need God＇s help. Thus, as Toni Morrison demonstrates, a thoroughly surreptitious, because natural, process of dissolution of all barriers makes them appear to be arbitrary constructs responsible for the equally arbitrary notion of the Other. Taking an utterly holistic view of the nature of things, Morrison seems to suggest that borderlines are a consequence and a manifestation of a lack of balance, which therefore needs to be redressed through love, mutual understanding, and maturation.

Myocardial enzyme activities of black bears and comparison with those of human beings

According to the principle of enzyme reaction rate, healthy pent black bears’ myocardial enzyme activity is assayed by visual colorimetry and compared with that of healthy human beings. The determination at 37 °C and the statistic analysis of the experimental data work out the following findings. For male black bears, the average CK activity is 163.20 U/L, the confidence interval of its expected value (127.70 to 198.70) U/L, and the coefficient of variation 39.2%; the average CK-MB activity 21.62 U/L, the confidential interval (17.72 to 25.51) U/L, and the coefficient of variation 34.26%; the average LDH activity 604.20 U/L, the confidence interval (524.56 to 683.83) U/L, and the coefficient of variation 23.80%; the average HBDH activity 516.70 U/L, the confidence interval (453.06 to 580.34) U/L, and the coefficient of variation 22.24%; the average GOT activity 69.70 U/L, the confidence interval (60.21 to 79.19) U/L, and the coefficient of variation 24.59%. For female black bears, the average CK activity is 145.50 U/L, the confidence interval (114.59 to 176.21) U/L, and the coefficient of variation 38.27%; the average CK-MB activity 18.84 U/L, the confidence interval (14.64 to 23.04) U/L, and the coefficient of variation 40.34%; the average LDH activity 563.70 U/L, the confidence interval (473.80 to 652.60) U/L, and the coefficient of variation 28.80%; the average of HBDH activity 475.50 U/L, the confidence interval (412.10 to 538.40) U/L, and the coefficient of variation 24.07%; the average of GOT activity is 62.37 U/L, the confidential interval (52.54 to 72.20) U/L, and the coefficient of variation 28.46%. The male black bear’s average myocardium enzyme activities are slightly higher than those of the female. But the statistical results indicate that the difference is not significant.

Production of Amylase Enzyme through Solid State Fermentation by Aspergillus niger

Traditionally, coconut dregs will be used as animal feed after the extraction of coconut oil and coconut milk from the copra. This study was carried out to discover the commercial value of coconut dregs as a solid substrate in the production of amylase through solid state fermentation （SSF） since this agro-waste is fairly rich in nutrients, providing the necessary nutrients supplementation for better microbial activity to produce enzymes. In this study, amylase is to be produced from coconut dregs by Aspergillus niger through solid state fermentation （SSF）. Three parameters were covered, which are incubation time, initial moisture content of substrate and inoculum sizes. SSF was carried out by using incubator at 37 ~C to test for enzyme activity at these following parameters： incubation time： 24, 48, 72, 96 and 120 hours; substrate moisture content： 64, 66, 68, 70 and 72% （w/w）; inoculum sizes： 0.5, 1.0, 1.5, 2.0, 2.5 and 3.0 mL spore suspension （5.5 × 10^6 spores/mL）. Enzyme activities were measured through the estimation of liberated reducing sugars after the assay of amylase enzyme by using DNS （3, 5 dinitrosalicylic acid） method. Highest enzyme activities were obtained at these following parameters： incubation time： 72 hours （31.76 U/gds）; initial moisture content ofsubstrate： 66% （26.66 U / gds） and inoculum sizes： 2.0 mL （30.56 U/gds）.

我国农村化粪池污染物去除效果及影响因素分析

探究农村化粪池污染物去除效果及主要影响因素对于理解我国农村化粪池粪污处理现状十分必要。本研究基于山西、陕西、浙江、湖南、广东和重庆6个选点区域57家农户化粪池的监测结果,分析了农村化粪池处理污染物的现状和主要影响因素。结果表明,区域化粪池对化学需氧量(COD)、5日生化需氧量(BOD_(5))、氨氮(NH_(3)-N)、总氮(TN)、总磷(TP)、动植物油(AVO)的削减率范围分别为21%~65%、29%~72%、−12%~−2%、4%~12%、7%~21%、34%~62%,整体表现为广东>浙江>湖南>重庆>山西>陕西;由于对居民用排水习惯、化粪池纳污来源的影响,温度、湿度、降雨量与化粪池污染物浓度及其去除率有较好的相关性。该研究结果可为化粪池去污效能的改善以及相关政策的制定提供参考。

犯错的年纪可以很精彩

现在回过头来看这段把每一天过得像世界末日一样的日子,感觉就像一场恍惚的梦,所有的苦和累都已经记忆模糊,唯一清晰记得的是完成作品的那天早上,我们五个人肩并肩地走在十一月阳光和煦的校园林荫道上,顶着大大的黑眼圈,笑得比阳光还灿烂……＂我一辈子都喜欢跟着让我感觉有趣的人在一起,因为在我心目中,真正的人都是疯疯癫癫的,他们热爱生活,爱聊天,不露锋芒,希望拥有一切,他们从不疲倦。
