不同培养条件对纤维素酶产量和酶活力影响的研究

本试验采用均匀设计U_(to)(10~7)研究影响绿色木霉生产纤维素酶的五大因素(培养温度、加水倍数、底物粗纤维水平、初始pH值、培养时间),试图找出培养条件最佳组合,取得高酶产量和酶活力。结果表明:当底物粗纤维水平为50％,初始pH值为8.0。加水3.5倍,在27℃条件下培养55h,可取得最大酶产量28.09mg/g和CMC酶活力27.16mg/g.h,棉花酶活力33.26mg/g.24h。     

“礼、乐、仁、和”的字形理据及儒家文化阐释

汉字为表意文字,从字形我们就能判断其意义类属,也能推断出与之相关的思想文化内涵。儒家美学思想以“仁”为核心,以“礼”、“乐”为具体的实现途径,在充分肯定文艺的社会功能的时候,将“礼”“乐”作为教化人心的手段,提倡礼乐和谐观。本文从古文字“礼”、“乐”、“仁”、“和”的字形入手,试图通过这几个概念的解析,揭示儒家美学思想的内涵。

"突击文化"的历史内涵及其对延安文学研究的意义

"突击文化"是对延安文学发生语境的一种概括。它集中反映了抗日革命根据地社会日常生活的军事化色彩、为建立现代民族国家的"焦虑"心态,以及潜在的"突围"心理。从"突击文化"的角度研究延安文学,能够使延安文学研究从"政治"的视野步入更深入的"文化"空间,进而丰富我们对延安文学内在复杂性的认识。通过"突击文化",我们可以更新对于延安文学的认识结构。

Caesarean delivery before 39 weeks associated with selecting an auspicious time for birth in Taiwan

BackgroundCaesarean delivery before 39 weeks of gestation increases the risk of morbidity among infants. Taiwan has one of the highest caesarean rates in the world, but little attention has been paid to this issue. This study aimed to describe the rate of caesarean delivery before 39 weeks gestation among women who did not have labour signs and had a non-emergency caesarean delivery in Taiwan and to examine whether the phenomenon was associated with the Chinese cultural practice of selecting an auspicious time for birth.MethodsWe recruited women at 15–28 weeks of pregnancy at 5 hospitals in northern Taiwan and followed them at 4 or 5 weeks after delivery using structured questionnaires. This analysis included 150 primiparous mothers with a singleton pregnancy who had a non-emergency caesarean delivery without the presence of labour signs.ResultsNinety-three of these women (62.0%) had caesarean deliveries before 39 weeks of gestation. Logistic regression analysis showed that women who had selected an auspicious time for delivery (OR = 2.82, 95% CI: 1.15–6.95) and delivered in medical centres (OR = 5.26, 95% CI: 2.25–12.26) were more likely to deliver before 39 weeks of gestation.ConclusionNon-emergency caesarean delivery before 39 weeks of gestation was common among the study women, and was related to the Chinese cultural practice of selecting an auspicious time for birth. Further studies are needed to examine the risks and benefits associated with timing of caesarean delivery in Taiwan in order to generate a consensus among obstetricians and give pregnant women appropriate information.
