中国城市形状的时空变化

Wang, Xinsheng(王新生); Liu, Jiyuan(刘纪远); Zhuang, Dafang(庄大方); Jiang, Youhua(姜友华); Zhang, Hong(张红); Yu, Ruilin(余瑞林)

[中文摘要]:基于国家资源环境数据库动态土地利用数据,计算了1990年和2000年我国31个大城市的形状指数。结果表明,从1934年~1990年的56年间城市形状从紧凑趋于非紧凑、分散;而在1990年~2000年10年间,由于受到城市建设用地控制增强的影响,城市形状趋于紧凑。从1934年~1974年间,在20个可比较的城市中有14个城市形状指数增加、6个城市形状指数减少。从1974年~1990年间,在22个可比较的城市中各有11个城市的形状指数增加和减少。从1990年~2000年间,31个城市中有11个城市的形状指数增加、20个城市形状指数减少。一些城市的形状指数在不同时间段变化...

The Surface Morphology and Fine Structure of CHO (Chinese Hamster Ovary) Cells Following Enucleation

Shay, J. W.; Prescott, D. M.; Porter, K. R.

Chinese hamster ovary cells grown in monolayer culture and exposed to cytochalasin B were enucleated by centrifugation. Thereafter, the karyoplasts (the nucleated parts obtained from the bottoms of the centrifuge tubes) and the cytoplasts (the enucleated cytoplasmic parts attached to the coverslips)...

The Chinese names of the four directions

Sagart, Laurent

It is shown that the Old Chinese terms for the four directions form two etymological pairs, one of which (north-south) relates to the notions of front and back (of the house: houses faced south in early China ) and the other (east-west) to notions of beginning vs. ceasingmovement, applied to t...

Role of the A subunit of pertussis toxin in alteration of Chinese hamster ovary cell morphology.

Burns, D L; Manclark, C R; Kenimer, J G

The mechanism by which pertussis toxin induces morphological changes in Chinese hamster ovary cells was studied to determine whether the resulting clustered growth pattern is due to toxin-catalyzed ADP-ribosylation of a cellular substrate. While pertussis toxin was extremely potent in inducing morph...

Radical pro drop and the morphology of pronouns

Neeleman, A.; Szendrői, K.

We propose a new generalization governing the crosslinguistic distribution of radical pro drop (the type of pro drop found in Chinese). It occurs only in languages whose pronouns are agglutinating for case, number, or some other nominal feature. Other types of languages cannot omit pronouns freely, ...

On intransitive nasal prefixation in Sino-Tibetan languages

Sagart, Laurent

The author discusses alternations of voiced and voiceless stop initials in intransitive/transitive pairs in Tibeto-Burman languages in the light of Chinese facts. He suggests that it is not necessary to suppose two distinct processes in proto-Tibeto-Burman to account for the facts, as Benedict's “al...

Depletion of phosphatidylcholine affects ER morphology and protein traffic at the Golgi complex.

Testerink, N.; Sanden, Michiel Henrik Marie van der; Houweling, M.; Helms, J.B.; Vaandrager, A.B.

The mutant Chinese hamster ovary cell line MT58 contains a thermosensitive mutation in CTP:phosphocholine cytidylyltransferase, the regulatory enzyme in the CDP-choline pathway. As a result, MT58 cells have a 50% decrease in their phosphatidylcholine (PC) level within 24 h when cultured at the nonpe...

Rebhun, Lionel I.; Guerrant, Richard L.; Schnaitman, Terry C.; Brunton, Laurence L.; Gilman, Alfred G.

The major limitation to our understanding of the clinical importance of enterotoxigenic Escherichia coli in diarrheal illness has been the lack of a simple rapid assay for the enterotoxin produced by certain E. coli. On the basis of the activation of adenylate cyclase by heat-labile enterotoxin of E...
