滇重楼可持续采收方法初探

滇重楼是云南传统的道地药材。由于种苗繁育困难和生长周期长,重楼的推广种植多年来未能取得突破。滇重楼的"多年栽培,分期采收"技术是将滇重楼根茎按用途分为药用部分与种苗部分,采收时,仅采收药用部分,种苗部分(带顶芽的根茎)继续生长发育,而不是将整个根茎全部采收作为商品药材。通过考察滇重楼须根比率的月度变化规律及3年的根茎生长量,进行采收时间和经济效益分析。结果表明:实施滇重楼"多年栽培,分期采收"技术间隔时间以3年为宜,每年每公顷收益为11.25万～33.0万元,采收时间以12月至翌年3月份为宜。     

Urbanization disrupts latitude‐size rule in 17‐year cicadas

Many ectotherms show a decrease in body size with increasing latitude due to changes in climate, a pattern termed converse Bergmann's rule. Urban conditions—particularly warmer temperatures and fragmented landscapes—may impose stresses on development that could disrupt these body size patterns. To test the impact of urbanization on development and latitudinal trends in body size, we launched a citizen science project to collect periodical cicadas (Magicicada septendecim) from across their latitudinal range during the 2013 emergence of Brood II. Periodical cicadas are long‐lived insects whose distribution spans a broad latitudinal range covering both urban and rural habitats. We used a geometric morphometric approach to assess body size and developmental stress based on fluctuating asymmetry in wing shape. Body size of rural cicadas followed converse Bergmann's rule, but this pattern was disrupted in urban habitats. In the north, urban cicadas were larger than their rural counterparts, while southern populations showed little variation in body size between habitats. We detected no evidence of differences in developmental stress due to urbanization. To our knowledge, this is the first evidence that urbanization disrupts biogeographical trends in body size, and this pattern highlights how the effects of urbanization may differ over a species’ range.     

学术类科技期刊正文转接的原则与技巧

通过编辑实践经验,对学术类科技期刊正文转接的原则和技巧进行总结提炼。阐述了尽量避免跳页排印、以少接多、顺势接排、尽量避免逆向转接、分段或分句转接、不能出现背题的接排、含图表和公式部分不宜转接、应避免转接错误和字体混乱等8条原则以及具体实施的技巧,认为处理正文转接的最适宜时期是清样"定版"环节,其目的在于不断提高编辑工作的效率和期刊的编辑质量。

Crossflow filtration of baker's yeast with periodical stopping of permeation flow and bubbling

The periodical stopping of permeation flow was applied to increase the permeation flux in crossflow filtration of commercially available baker's yeast cell suspension. The permeation flux after 3 h filtration in the crossflow filtration increased to 8 x 10(-5) m(3) /m(2) s (290 L/m(2) h) from 2 x 10(-5) m(3)/m(2) s (72 L/m(2) h) by applying the periodical stopping of permeation. Introduction of air bubbles during the stopping period of permeation further increased the flux.(c) John Wiley & Sons, Inc.
