典权基本问题研究  [PDF]
房绍坤,吕忠民
法学研究 , 1993,
Abstract: 典权是我国传统的特有法律制度。随着我国民事立法的逐步完善,许多学者建议在我国未来的民事立法中确认典权制度,并论证了其可行性。我们对此表示赞同。在立法上确认典权制度,首先必须从理论上明确典权的基本问题。为此,我们拟结合我国的典权司法实践,借鉴近代典权立法,对典权的法律性质、设定、当事人的权利等基本问题作一探讨,并就此提出典权立法的初步构想。
月壤及模拟月壤微观结构的研究  [PDF]
李丽华,唐辉明,刘数华
岩土力学 , 2012,
Abstract: 为了对比研究月壤与模拟月壤的微观结构,介绍了月壤的形成作用过程和5种基本颗粒类型;通过真实月壤照片,对月壤微观结构进行了分析;利用火山灰为模拟月壤主体材料,对其成分进行了检测;对模拟月壤的火山灰颗粒进行了显微图像分析试验。结果表明,月壤存在胶结物微观颗粒,胶结物颗粒具有分支的组织形态和封闭的气泡,并且有金属铁珠存在;火山灰所含的主要成分及含量与月壤相似,经过粉碎的火山灰试样棱角较为明显,其纵横比峰值略小,稍显长条状,但与月壤比较相近,而复杂度因子则略有欠缺,说明颗粒还不够粗糙和多棱
汉代察举制概论  [PDF]
赖华明?
天府新论 , 2003,
Abstract: 察举制是汉代实行的一种自下而上推选人才为官的制度。通过察举制的实施,汉王朝选拔了一大批德才兼备的人才,不仅充实和加强了中央和地方的封建统治机构,而且对当时社会政治、经济、文化的发展也起了一定的推动作用。弄清楚察举制度产生与演变的规律、特点、内容及其在推行中利弊得失,对于研究汉代的官吏选拔制度和政治管理制度有一定的学术理论意义。

Infections by protozoa in immunocompromised hosts
Ferreira, Marcelo Sim?o;
Memórias do Instituto Oswaldo Cruz , 2000, DOI: 10.1590/S0074-02762000000700026
Abstract: protozoa are among the most important pathogens that can cause infection in immunocompromised patients. they infect particularly individuals with impaired cell immunity, such as those with hematologic neoplasias, those submitted to transplant of solid organs, those under high-dose corticosteroid therapy, and carriers of the human immunodeficiency virus. among the protozoa that most commonly cause disease in immunocompromised individuals are toxoplasma gondii, trypanosoma cruzi, cryptosporidium parvum, isospora belli, cyclospora cayetanensis and microsporidia; the former two cause severe encephalitis and myocarditis, and the others cause gastrointestinal infections. early diagnosis and prompt institution of specific therapy for each of these organisms are basic measures to decrease morbidity and mortality associated with these infections.

关于编纂《中国地层典》的总结  [PDF]
中国地层典编办公室
地质通报 , 2001,
Abstract: 受《中国地层典》编委会的委托,就编纂《中国地层典》的情况向大家作一汇报。1 编典任务的由来和组织实施概况编纂《中国地层典》是第二届全国地层委员会为筹备召开第三届全国地层会议而组织实施的两项重要业务总结的准备工作之一。自1959年第一次全国地层会议后,随着中国地层工作的飞速发展,编纂系统的《中国地层典》成为中国广大地层工作者多年来的夙愿。60年代中后期,中国著名地质学家、地层工作的先驱者之一尹赞勋教授率先主持试编了《中国地层典(七)石炭系》,做了开创性的工作。后因十年动乱而终止。至80年代末,全国地层委员…
《尚书?尧典》乐论辨证  [PDF]
李壮鹰
安徽大学学报(哲学社会科学版) , 2010,
Abstract: 《尚书?尧典》载有一段帝舜与夔的论“乐”文字,传统上一直被作为考察上古之诗乐情况和诗学观念的信史来使用。其实,它只是后人对古代的传说。这种传说固然也保留了某些上古的历史信息,但真史经过几千年传说的陶铸,也就存在着以讹传讹的严重变形。从文字考辨和神话解析入手,考索后可知,“诗言志”四句之纂入《尚书?尧典》,至早亦当在战国末期甚至以后。
Secretory organelles of pathogenic protozoa
Souza, Wanderley de;
Anais da Academia Brasileira de Ciências , 2006, DOI: 10.1590/S0001-37652006000200008
Abstract: secretory processes play an important role on the biology and life cycles of parasitic protozoa. this review focus on basic aspects, from a cell biology perspective, of the secretion of (a) micronemes, rhoptries and dense granules in members of the apicomplexa group, where these organelles are involved in the process of protozoan penetration into the host cell, survival within the parasitophorous vacuole and subsequent egress from the host cell, (b) the maurer's cleft in plasmodium, a structure involved in the secretion of proteins synthesized by the intravacuolar parasite and transported through vesicles to the erythrocyte surface, (c) the secretion of macromolecules into the flagellar pocket of trypanosomatids, and (d) the secretion of proteins which make the cyst wall of giardia and entamoeba, with the formation of encystation vesicles.
