Changing NPP consumption patterns in the Holocene: From megafauna-‘liberated’ NPP to ‘ecological bankruptcy’ [PDF]
The Anthropocene Review, 2016 There have been vast changes in how net primary production (NPP) has been consumed by humans and animals through the Holocene. Here we ask: how much NPP energy may have become available following the megafauna extinctions? When did humans, through agriculture and livestock, consume more NPP than wild mammals?

Unexpected contribution of cloud seeding to NPP increase during drought
Hydrology ResearchCloud seeding is generally used to secure additional water resources, which is not an easy goal to achieve, as the spatial variability of rainfall is high. Instead, the increased rain may moisten the neighboring forest.

NPP-VIIRS-like nighttime light data (1992-2020) in Hangzhou
, 2023 The NPP-VIIRS-like nightime light data from 1992 to 2020. The night light time series from 1992 to 2011 was obtained by converting DMSP-OLS to NPP-VIIRS.

Developmental Biology, 2006 Nucleoporins are components of the nuclear pore, which is required for nucleo-cytoplasmic transport. We report a role for a subclass of nucleoporins in orienting the mitotic spindle in C. elegans embryos. RNAi-mediated depletion of any of five putative nucleoporins npp-1, npp-3, npp-4, npp-11, and npp-13 leads to indistinguishable spindle orientation ...

Electrical and Thermomechanical Co-Simulation Platform for NPP [PDF]
, 2021 In order to analyze the safety of nuclear power plants (NPP), interactions between thermomechanical and automation processes, the on-site electrical grid, and the off-site transmission system should be studied in detail.

Aircraft Impact Effects on an Aged NPP [PDF]
Materials, 2021 The impact of an aircraft is widely known to be one of the worst events that can occur during the operation of a plant (classified for this reason as beyond design). This can become much more catastrophic and lead to the loss of strength of/collapse of the structures when it occurs in the presence of ageing (degradation and alteration) materials ...
