Drinking water microbiome assembly induced by water stagnation

open access: yesThe ISME Journal, 2018
What happens to tap water when you are away from home? Day-to-day water stagnation in building plumbing can potentially result in water quality deterioration (e.g., lead release or pathogen proliferation), which is a major public health concern. However,

Russian Economy: Between Crisis

open access: yesProstranstvennaâ Èkonomika, 2020
The article analyzes the dynamics of the Russian economy during the crisis of 2015–2016 and subsequent stagnation in 2017–2019. The main components of economic policy are examined and institutional trends that determine macroeconomic dynamics, in ...

Designing and Arranging a Model for Revival Stagnant Industrial Enterprises (Case Study: Kermanshah Province) [PDF]

open access: yesچشم‌انداز مدیریت صنعتی, 2020
Revival is not an isolated event, but a process that forms a series of events. The present qualitative research was designed with the aim for arranging a model for revival stagnant industrial enterprises using the grounded theory and a systematic ...

Stagnation–saddle points and flow patterns in Stokes flow between contra-rotating cylinders [PDF]

open access: yes, 1998
The steady flow is considered of a Newtonian fluid, of viscosity mu, between contra-rotating cylinders with peripheral speeds U-1 and U-2 The two-dimensional velocity field is determined correct to O(H-0/2R)(1/2), where 2H(0) is the minimum separation of

Emission characteristics and dynamics of the stagnation layer in colliding laser produced plasmas [PDF]

open access: yes, 2010
The expansion dynamics of ion and neutral species in laterally colliding laser produced aluminum plasmas have been investigated using time and space resolved optical emission spectroscopies and spectrally and angularly resolved fast imaging. The emission

Stress singularities and the formation of birefringent strands in stagnation flows of dilute polymer solutions

open access: yes, 2009
We consider stagnation point flow away from a wall for creeping flow of dilute polymer solutions. For a simplified flow geometry, we explicitly show that a narrow region of strong polymer extension (a birefringent strand) forms downstream of the ...

Experimental characterization of the stagnation layer between two obliquely merging supersonic plasma jets

open access: yes, 2013
We present spatially resolved measurements characterizing the stagnation layer between two obliquely merging supersonic plasma jets. Intra-jet collisionality is very high ($\lambda_{ii} \ll 1$mm), but the inter-jet ion-ion mean free paths are on the same

Increase of data and development of science [PDF]

open access: yesروش 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.
