On the Experimental Study of the Flow through the Cascade of Partial Admission Turbine by Means of Shallow Water Table [PDF]
, 1964 Unsteady flow effects are important in all turbomachinery,but the analysis of the unsteady flow in a rotating blade passage of gas or steam turbine is very difficult due to many factors.

Functional Ecology, Volume 40, Issue 5, Page 1151-1164, May 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract Plant phenology is crucial for understanding plant growth and climate feedback. It affects canopy structure, surface albedo, and carbon and water fluxes. While the influence of environmental factors on phenology is well‐documented, the role of plant intrinsic factors ...

基于海绵城市的历史文化街区水安全体系构建——以厦门市鼓浪屿为例 [PDF]
, 2016 历史文化街区同现状多数老旧城区一样面临城市内涝安全问题,因此需要在保护历史文化街区的认知下,寻求一种有效解决现存的水安全问题的对策。通过分析梳理鼓浪屿的城市肌理、街巷空间及风貌建筑等历史文化街区的特性,结合鼓浪屿特有的城市地理环境,建立鼓浪屿全岛的排水模型,对常规雨水及超常规内涝防治系统进行评估提升,提出街区最优的改造策略 ...

Jellyfish blooms restructure plankton dynamics and trophic linkages in coastal waters
Functional Ecology, Volume 40, Issue 5, Page 1443-1460, May 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract Jellyfish blooms are increasing globally in frequency and intensity, introducing complex ecological interactions, yet the mechanisms by which they alter ecosystem structure remain poorly characterized due to a lack of sustained field observations.

Effects of P38MAPK on hydrocephalus and AQP4 expression in rats [PDF]
, 2017 交通性脑积水（CommunicatingHydrocephalus）是许多原发疾病如脑肿瘤、脑出血、脑外伤和颅内感染等引起的继发性表现。目前治疗手段多以手术分流为主，但术后堵管、感染等并发症的发生率高。诸多研究认为水通道蛋白4（Aquaporin4，AQP4）可在脑积水的病程中高表达，在一定程度上具有拮抗脑积水进展的作用，但具体调控机制仍未明确。P38丝裂原活化蛋白激酶（P38mitogen-activatedproteinkinase，P38MAPK）是体内信号传递的交汇点 ...

Kinetic model for polysaccharide's extraction from Taxus by water(红豆杉多糖浸提过程动力学模型)
Zhejiang Daxue xuebao. Lixue ban, 2008 对红豆杉多糖热水浸提的过程进行了动力学分析并建立了动力学模型.该模型适用于原料是细颗粒的外扩散控制过程，并且原料中溶质含量较大，溶质在溶剂中的溶解度相对较小.模型的主要特点是：将浸水后的原料看成由固相和渗透水相两相组成，并考虑多糖从固相到渗透水相的持续溶出效应，即在浸提起始阶段，少部分溶质溶出到渗透水相使其达到溶解饱和，然后剩余溶质不断溶出并维持渗透水相处于该饱和状态，这个阶段称为“饱和扩散”阶段，是多糖浸提的主要阶段.模型能较好地反映红豆杉多糖的浸提过程.根据“持续溶出效应 ...
