Response of air stagnation frequency to anthropogenically enhanced radiative forcing

Environmental Research Letters, 2012
Stagnant atmospheric conditions can lead to hazardous air quality by allowing ozone and particulate matter to accumulate and persist in the near-surface environment.

Increase of data and development of science [PDF]

روش شناسی علوم انسانی, 2019
Despite what it may seem, some indicators show that during the last quarter of twentieth-century science has been in the state of stagnation and there is less news about big discoveries.

The Stokes conjecture for waves with vorticity [PDF]

, 2012
We study stagnation points of two-dimensional steady gravity free-surface water waves with vorticity. We obtain for example that, in the case where the free surface is an injective curve, the asymptotics at any stagnation point is given either by the “

A numerical study of the ferromagnetic flow of Carreau nanofluid over a wedge, plate and stagnation point with a magnetic dipole

, 2020
Present communication mainly addresses the fluid transport characteristics of ferromagnetic Carreau nanofluid over a porous wedge, plate, and stagnation point with magnetic dipole effect for shear thinning/shear thickening cases. Suitable self-similarity

Delayed Release of Intracellular Microcystin Following Partial Oxidation of Cultured and Naturally Occurring Cyanobacteria

Toxins, 2020
Oxidation processes can provide an effective barrier to eliminate cyanotoxins by damaging cyanobacteria cell membranes, releasing intracellular cyanotoxins, and subsequently oxidizing these toxins (now in extracellular form) based on published reaction ...

Oblique Stagnation Point Flow of Nanofluids over Stretching/Shrinking Sheet with Cattaneo-Christov Heat Flux Model: Existence of Dual Solution

Symmetry, 2019
In the present work we consider a numerical solution for laminar, incompressible, and steady oblique stagnation point flow of Cu − water nanofluid over a stretching/shrinking sheet with mass suction S .

Stagnation and Scientific Incentives

, 2020
New ideas no longer fuel economic growth the way they once did. A popular explanation for stagnation is that good ideas are harder to find, rendering slowdown inevitable.

A Simulative Approach for the Prediction of Mesoscale Residual Stress Fields in Solution‐Strengthened Ferritic Ductile Iron

Advanced Engineering Materials, EarlyView.
This study presents a 3D representative volume element‐based simulation approach to predict mesoscopic residual stress and strain fields in silicon solid solution‐strengthened ductile cast iron. By modeling phase transformation kinetics with an enhanced Johnson–Mehl–Avrami–Kolmogorov model, the effects of varying cooling rates on residual stresses are ...

Pathways to Prosperity: Navigating Post-Stagnation Growth and Revitalizing Business

Economies
This study examines the ways in which firms recover from stagnation or sales decline, with a focus on two key aspects: traditional high-growth companies and growth restarts within the framework of organizational life cycle theory.
