The results of the experimental work highlighted the successful application of the synergic combination of alkali, surfactant and CO2 gas for improving recovery of medium gravity crudes.
Mountain Resorts Development Co., a state-run company, said in a statement that the "Sadzele ski lift in Gudauri stopped working, chairs crashed into each other with riders suspended in the air, causing health injury of medium gravity," according to CNN.

To explore the capabilities and limitations of the model, case studies including percolation of a single fluid in a porous medium, gravity current of a single fluid over a porous medium, multi-fluid flow over an impermeable bed, and a porous medium were simulated and compared with experimental data.
The vessel was then inverted and suspended above the level of the flow cell on a retort clamp stand, allowing the flow of medium by gravity, thus reducing the work of the peristaltic pump.
The filters are divided by the force that causes filtration: vacuum (i.e., a negative pressure at the filter medium), gravity alone (i.e., the hydrostatic head of the liquid above the medium), centrifugal force (i.e., an amplified gravity effect), fluid pressure (imposed by the suspension feed pump), mechanical pressure (a squeezing effect), and the use of other force fields.
The API gravities of the two crude oil samples were found to be 23° and 31°API, indicating that the oil field produces medium gravity crudes.
The testing fluids were a medium gravity crude oil, seawater concentration brine, formation equivalent brine and the carbonated version of these brines.
where g is gravity acceleration, η is viscosity of medium, ϱ is density of medium, ϱ p is density of aggregating particles, d i is diameter of particle i.
The problem (1.1)–(1.4) can be used as models to describe the motion of a fluid in a container or to describe the displacement of a fluid in a medium without gravity; see [1 5] for more information.
Individual faecal egg counts were determined by using the Flotac technique [ 20] with a sensitivity of two eggs per gram (EPG) of faeces, using a sucrose flotation medium (specific gravity = 1.250).
