Advanced Science, EarlyView.In the pathological context of osteoarthritis (OA), the phosphorylation of AKT1 at Ser473 enhances its binding to Lys140 of Insig1, which facilitates the formation of AKT1–Insig1 complex. Subsequently, the activation of AKT1 promotes the phosphorylation of Insig1 at Ser189, potentially enhancing the dissociation of Insig1 from sterol regulatory element‑

Improving energy dissipation on stepped spillways using breakers
Ain Shams Engineering Journal, 2018 Stepped spillways have many applications in dam structures, and river engineering. Moreover, stilling basins can be constructed with lower costs as energy dissipation by adding appurtenances to these stilling basins.

Groundwater Rise Sustains the World's Largest Alpine Water System Under Global Warming
Advanced Science, EarlyView.Shallow groundwater depth (SGWD) across the non‐permafrost plains of the Qinghai–Xizang Plateau decreased at averagely 0.02 m year−1, adding 31.44 Gt of freshwater storage from 2000 to 2020 and sustaining ∼53 500 km2 of alpine ecosystems. A vadose‐zone capacity of 426.6 Gt reveals these aquifers as promising reservoirs, highlighting groundwater's ...

Investigation of Hydraulic Jump Turbulence Parameters in Divergent Rectangular Sections using Fluent Model [PDF]
علوم و مهندسی آبیاری, 2018 A Stilling basin with divergent section has better performance and lower constructional costs than the classic basin. It can easily adapt itself to the upstream and downstream conditions in terms of depths and cross sections (Omid et al., 2007).
