The stellar populations of spiral disks.II Measuring and modeling the radial distribution of absorption spectral indices [PDF]

open access: yes, 1998
The radial distributions of the Mg2 and Fe5270 Lick spectral indices have been measured to large radial distances on the disks of NGC 4303 and NGC 4535 using an imaging technique based on interference filters.

HYDRODINAMIC MODEL OF BIOREACTORS WITH IMMOBILIZED MICROORGANISMS AT WASTEWATER TREATMENT

open access: yesWATER AND WATER PURIFICATION TECHNOLOGIES. SCIENTIFIC AND TECHNICAL NEWS, 2013
With the purpose of provision of necessary mass exchange it is developed new constructions of anaerobic and aerobic bioreactors with fibrous carriers for microorganisms immobilization. Constructive peculiarity of anaerobic bioreactor is the mixing system with using of pump, recirculated pipe and perforated pipe which is placed along of the central line

Relativistic hydrodynamics - causality and stability

open access: yes, 2007
Causality and stability in relativistic dissipative hydrodynamics are important conceptual issues. We argue that causality is not restricted to hyperbolic set of differential equations. E.g. heat conduction equation can be causal considering the physical

Calculation of vertical seismic hydrodinamic loads [PDF]

open access: yes, 2017
This paper analyzes Zangar's method for calculation of seismic hydrodynamic loads acting at the inclined contour of a concrete gravity dam. Different numerical models are compared with the procedure proposed by Zangar, and the regression formula that eliminates the observed discrepancies is proposed.

Effects of air-lift reactor dimensions on its hydrodinamic characteristics

open access: yesHemijska industrija, 2010
In this study the hydrodynamic characteristics of the external loop airlift bioreactors were investigated. The influence of reactor height and solid particles concentration on the mean liquid circulation velocity was examined. Also, the possibility of theoretical prediction of this liquid circulation velocity was assessed.
