Functional Ecology, Volume 40, Issue 4, Page 983-1000, April 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract Organic phosphorus mineralization is a critical process in the phosphorus cycle, governing phosphorus bioavailability for plants. The PhoD gene, which encodes the key enzyme alkaline phosphatase, serves as a valuable biomarker for this process.

Shuitu Baochi Xuebao, 2011 应用猪场废水处理工程中产出的厌氧水不同灌溉量和3个处理阶段出水与地下水按体积比1∶5混合对冬小麦-夏玉米轮作系统进行3年的小区灌溉试验,监测地下水的总矿化度及钾、钙、钠、镁等含量的变化。结果表明:(1)地下水中钾含量在厌氧水不同灌溉量条件下呈现高量厌氧水(Ha)>中量厌氧水(Ma)>低量厌氧水(La)的变化趋势,在混水灌溉处理地下水中钾含量均呈厌氧水与地下水1∶5混合(Tag)>原水与地下水1∶5混合(Tog)>仿生态塘水与地下水1∶5混合(Teg)的变化趋势;(2)地下水中钠、钙 ...

Novos Estudos - CEBRAP, 2021 O objetivo deste artigo é argumentar que situações de privação material são inerentemente coercitivas. Para isso, avaliam-se teorias da justiça para as quais a pobreza não representaria uma forma de intervenção coercitiva em contextos de livre-mercado. Argumenta-se aqui que a pobreza precisa ser concebida como uma posição social subordinada e, portanto,

Laser‐Driven Halide Exchange and High‐Resolution Multicolor Patterning of Perovskite Films
Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT Translating the excellent properties of metal halide perovskites (MHPs) into practical flexible optoelectronic devices requires high‐resolution multicolor patterning techniques that are compatible with post‐fabrication processing. However, such a capability has remained elusive.

Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT Expanding near‐infrared (NIR) spectral response and utilizing ultraviolet (UV) photons are effective strategies for enhancing the power conversion efficiency (PCE) of lead halide perovskite solar cells (PSCs). However, the range of NIR spectral response extension and the utilization of UV light for devices are not enough, and the loss of ...
