宁波历史文化街区保护与更新存在的问题与对策研究

在对宁波历史街区保护与更新现状调查基础上,认为历史街区保护存在着建设性破坏和保护性衰败两大文化与社会困境。提出突破困境之路在于运用有机更新理论和方法,并从保护与延续整体历史原真性、生活真实性,保护与传承人文社会网络等方面,对历史街区的保护与更新方法进行探讨,以期达到对历史街区进行整体原真性保护与更新,维系发展人文活力和可持续发展的目标。     

有机胺型钻井液在盐227区块的应用

有机胺型钻井液的防膨性、抑制性和润滑性与油基钻井液接近,且其抗温性、滤失性、流变性和稳定性较好。在胜利油田盐227区块复杂地质条件下的应用中,有机胺型钻井液使得六口井的机械钻速平均提高了39．5％,井径扩大率平均为3．18％,钻井故障率大大降低,促进了该区块的开发。     

有机马克思主义对资本主义主流价值观的五大批判

有机马克思主义出现在全球性生态危机日益严重的时代背景之下。有机马克思主义认为资本主义及其价值观是生态危机形成的根源。为了克服日益严重的生态危机,有机马克思主义对资本主义极端个人主义价值观、自由观、人权观、民主观、正义观进行了深刻的批判,还分别建构了与改良生态相适应的价值观。有机马克思主义对资本主义价值观的批判对于克服全球性生态危机、促进人类与自然的良好发展具有一定的意义,但也不能从根本上解决生态问题。     

多种教学方法相结合的有机化学教学模式之我见——以《芳烃》为课例分析

在教学过程中,为了克服学生学习过程中对有机化学的各种畏难情绪及理论体系不明晰的感觉,有效的调动学生学习有机化学的积极性,加强对旧知识的巩固及新知识的掌握,提高教学的质量,文章将情景教学、问题教学、多媒体教学、模块化法、对比法等多种教学方法相结合的教学模式应用于有机化学《芳烃》一章教学进行了探讨,结果显示多种教学方法相结合的教学模式在有机化学教学中具有重要作用。     

Organic Acidurias: An Updated Review

Organic acidurias are an important class of inherited metabolic disorders arising due to defect in intermediary metabolic pathways of carbohydrate, amino acids and fatty acid oxidation. This review summarizes the current knowledge about the important organic acidurias in the Indian population. Specifically, diagnosis and principles of treatment of organic acidurias are covered. The salient features of common organic acidurias as well as their prevalence in various parts of the world are reviewed in some detail.     

Diagnosis of Major Organic Acidurias in Children: Two Years Experience at a Tertiary Care Centre

Organic acid disorders are inherited metabolic disorders in which organic acids accumulate in tissues and biological fluids of affected individuals. Classical organic acidurias include methylmalonic aciduria, propionic aciduria, isovaleric aciduria and maple syrup urine disease (MSUD). They are considered the most frequent metabolic disorders among severely ill children. Patients frequently present with acute symptoms early in life. 420 cases clinically suspected to have organic aciduria, with upper age limit of 12 years for a 2-year period (January 2007–December 2008) were enrolled into this study. Metabolic acidosis and neurological symptoms were the most common signs. Screening tests and thin layer chromatography were done for detection of organic acidurias. Identification and quantitation of organic acids in urine and quantification of amino acids in blood were done by high performance liquid chromatography. Out of 420 patients, 45 patients (10.7%) were found to have organic acidurias. 15 cases of methylmalonic aciduria, 16 cases of propionic aciduria, 13 cases of MSUD, and one case of isovaleric aciduria were diagnosed. Results demonstrate the importance of testing for organic acidurias. Since organic aciduria may cause irreversible brain damage if not treated, we recommend selective screening amongst severely ill children despite implied extra costs.     

简析工业有机热载体炉常见故障与防范措施

有机热载体锅炉是以煤、油或可燃气体为燃料,导热油为热能的载体,具有低压高温的工作特性,已被广泛应用于化工、纺织、印染、轻工、食品、造纸、建材等行业。但在实际使用中也发生一些危及安全的事故,给人民生命和财产造成了一定的损失。     

基于产品研发过程的有机合成类课程群建设构想

为解决有机合成类课程内容重复等问题,提出建设基于产品研发过程的有机合成类课程群的构想。从目标、内容组织、评价等方面探讨构建有机合成类课程群的体系和实施过程,并提出实施过程中应注意的问题。     

有机化学渐进式双语教学模式探讨

在我校多年教学实践的基础上提出了一套适合大学本科有机化学课程的渐进式双语教学模式,涉及到的有机化学课程包括基础有机化学、中级有机化学和有机合成,双语教学采用易于被学生接受的渐进式教学模式,使学生的专业英语水平逐步提高,达到能轻松阅读英文文献,利用网络数据库快速检索相关文献,因而使学生在专业领域有了更大的提升空间。
