作为水利水电工程建设大国，中国水利水电企业“走出去”仍然面临相对滞后的水电标准问题。从推动“一带一路”倡议、构建中国话语权和提升中国现代化程度的角度出发，初步构建水利水电工程移民社会融合状态全过程评估理论，并就总体框架、过程评估与结果评估进行了阐释。在过程评估上区分为规划期、安置期和后期扶助期；在结果评估上分为环境适应、人口发展、文化融合3个方面。以三峡工程为案例，初步检验了全过程评估理论的科学性、合理性与可行性。未来有关工程移民的研究还应拓展全过程评估的应用范围，进一步对社会重构问题给予足够的关注，并着力构建具有中国特色的评估体系。

Prokaryotes play a fundamental role in global ocean biogeochemical ***,how the abundance and metabolic activity of ecologically distinct subgroups(i.e.,high nucleic acid(HNA)and low nucleic acid(LNA)cells),and their regulating factors,change in response to changing marine environmental conditions remains poorly ***,we delved into the time-evolving dynamic responses of the HNA and LNA prokaryotic subgroups to declining resource availability and selective grazing by protozoa by conducting a 73-day incubation experiment in a large-volume(117,000 L)macrocosm that facilitates community-level *** found that the metabolic activity of the HNA subgroup was higher than that of the LNA subgroup when the macrocosm was resource replete but that the HNA subgroup declined more rapidly than the LNA subgroup as the resources became increasingly scarce,leading to a steadily increasing contribution of LNA cells to prokaryotic ***,as resources in the macrocosm became limited,protozoan grazing preference shifted from the HNA to the LNA subgroup and the contributions of the LNA subgroup to the carbon flow within the macrocosm *** findings highlight the resilience of LNA cells in resource-limited environments,illuminate the critical role of selective grazing by protozoa in balancing distinct prokaryotic subgroups under changing resource conditions,and demonstrate the complex and adaptive interactions between protozoa and prokaryotes across diverse environmental contexts.

As phase separation between the small-molecule semiconductor and the polymer binder is the key enabler of blend-based organic field-effect transistors(OFETs)fabricated by low-cost solution processing,it is crucial to understand the underlying phase separation mechanisms that determine the phase morphology,which significantly impacts device *** the parameter space investigated in previous work,here we investigate the formation of blends by varying the branch architecture of the polymer binder and by shortening the solvent dry time using ultrasonic spray *** phase morphologies of the resulting blend films have been thoroughly characterized with a variety of techniques in three dimensions over multiple length scales,including AFM,energy-filtered transmission electron microscope,and neutron reflectivity,and have been correlated with electrical transport *** the results,we have inferred that the phase morphology is kinetically determined,limited by the inherent slow movement of polymer *** kinetic picture,supported by molecular dynamics modeling,not only consistently explains our observations but also resolves inconsistencies in previous *** achieved mechanistic understanding will guide further optimization of blend-based organic electronics,such as OFETs and organic photovoltaics.

Human FⅨ expression vector pCMVⅨ was packaged by EffecteneTM reagent and injected into mice seminiferous tubules with glass pipettes. The expressional frame of pCMVⅨ was examined by PCR and Southern blotting among 41 progenies. There were 2 (4%) mice being integrated with hFⅨ gene into chromosomes. 4.6 ng/mL of hFⅨ protein was expressed in plasma of one mouse, which was tested by ELISA. We demonstrated that building of transgenic animals by spermatogonial stem cells is an efficient method. Meanwhile, it has also been proved to be an alternative choice for mammary gland bioreactor.
