知识型家庭的居住实态及住宅设计

住宅设计必须满足和适应住户的生活实态和意愿变化，不同的家庭类型有不同的生活实态的空间需求。知识型家庭是一个特殊的群体。本文通过对不同城市、不同职别的２２０户知识分子家庭的调查研究，提出知识型家庭的结构模型，记录了他们的居住实态，预测了其潜在的需求意愿，在此基础提出了适合知识型家庭使用的新住宅设计的几个重要结论

评吕夷简

北宋寿州吕氏,上承东莱吕蒙正,下启婺州吕祖谦,关键人物为吕夷简,宋仁宗在位40年,是北宋发展的顶峰,前20年由吕夷简辅政,巩固了北宋皇权,为社会稳定,经济发展作出了贡献。与此同时,封建经济社会的矛盾也在积累,吕夷简对此缺乏远见与对策,造成积重难返。     

壮族婚姻家庭与男女地位——壮族性别关系的研究之一

婚姻家庭是最能体现性别关系的社会基本形式。与稻作文明相联系,壮族婚姻家庭中的性别关系具有自己的显著特点,即都是男性占据主导的情况下,壮族妇女的地位高于当地汉族妇女。从神话传说所透露的远古信息来看,到了人猿揖别之后,壮族的婚姻家庭才逐渐形成并不断发展,与此相应的两性地位作用也随之发生改变;但是无论从“双轨制”运行的婚姻制度,还是从不成熟的父权家长制来说,都存在较多“性别平等”的意蕴。     

A new family of octocorals (Anthozoa: Octocorallia) from Cameroon waters

Acanthoaxis wirtzi, a new genus and new species of octocoral, is described and depicted for specimens collected in shallow water off Botha Island, Cameroon, West Africa. A new family, Acanthoaxiidae, is proposed to accommodate the new genus. The characters of this family are the total lack of sclerites; the axis having a narrow, hollow, soft, cross-chambered central core; and the axis surface having prominent spines.     

矩阵范数的界和方阵的ρ-条件数

The three-fingered protein domain of the human genome

Extracellular domains of some cellular receptors expressed in the organisms at different levels of development belong to three-fingered protein (TFP) fold. The Homo sapiens genome encodes at least 45 genes containing from one to three TFP domains (TFPDs), namely diverse paralogues of the Ly6 gene, CD59 and the receptors of activins, bone morphogenetic proteins, Mullerian inhibiting substance and transforming growth factor-β. C4.4a and urokinase/plasminogen activatory receptor contain two and three TFPD repeats, respectively. These diverse proteins have a low overall sequence similarity with each other and their hydrophobicity levels vary to a considerable degree. It is suggested that sequence differentiation within the TFPD led to distinct groups of proteins whose attributes were optimized to fit both the physicochemical properties specific to their functional microenvironment and selective targeting of their highly diversified extracellular cofactors.
