Physicochemical Conditions and Diversity of Macrobenthos of Village Creek, Texas
The Southwestern Naturalist, 1978Physicochemical conditions and benthic macroinvertebrates were studied in Village Creek, a southeast Texas clean water stream. Physicochemical conditions varied seasonally, downstream and with discharge. A total of 143 taxa of macrobenthos were collected and the number at each station ranged from 44 to 98. Diversity was determined by Shannon's index (d)

Modeling and analysis of physicochemical processes in recirculating water conditioning
Journal of Mining Science, 2015The current technologies of mineral mining, processing and beneficiation require introduction of closed water circulation. A common ecological and technological objective is in this case reduction of concentration of copper and commercial-grade fat acid ions that worsen flotation.

Stationarity conditions for physicochemical processes in the interior ballistics of a gun
Combustion, Explosion and Shock Waves, 1995An original method is proposed for ensuring time-invariant (stationary) interior ballistic parameters in the postprojectile space of a gun barrel. Stationarity of the parameters is achieved by investing the solid-propellant charge with highly original structures that produce the required pressure condition and linear growth of the projectile velocity ...

[Effect of cultivation conditions on the physicochemical properties of exopolysaccharide ethapolan].
Prikladnaia biokhimiia i mikrobiologiia, 2009The physicochemical properties of the complex exopolysaccharide ethapolan (EPS) produced by Acinetobacter sp. 12S during growth on media with various C/N ratios and different concentrations of mineral components and phosphate buffer were studied. Irrespective of the cultivation conditions, the concentrations of carbohydrates (38-44%) and pyruvic acid ...
