A device to enhance the delivery of a drug or other substance of interest into a selected organ or tissue, comprising special electrodes, one of the electrodes carrying a container with the selected drug or other substance of interest, said electrodes being capable of being positioned at preselected locations of said organ or tissue, wherein the electrodes are all connected with a selected energy source which generates and maintains an energy field before and during the enhanced delivery of said substance, under the influence of which delivery is accomplished in a direction from the active to the passive electrode and into said organ or tissue. The energy source may be selected from suitable sources providing an electric field, a magnetic field, ultrasonic waves, high energy waves like laser beams, or a combination thereof. Further a method for the enhanced delivery of said drug or other substance of interest to an internal organ or target tissue of an organism, for example the brain, bypassing the blood-brain barrier, is disclosed.

The method and apparatus for making a micro-dispersed gas-liquid mixture which includes a gas-liquid ejector unit, a cavitation unit and a jet dispersing unit installed in a sequence. All above referenced units are installed into a cylindrical housing which in turn includes bottom and top covers and also has a first partition having a conical orifice separating a gas-liquid ejector unit from a cavitation unit and a second partition separating a cavitation unit from a jet dispersing unit. The gas-liquid ejector unit has an inlet located at the bottom of the cylindrical housing for liquid and the inlet located on side surface of housing for gas, these being between bottom cover of the housing and the first partition. In addition, the inlet for liquid is a nozzle the top having both outside and inside parts of which are adapted to the conical orifice of first partition to provide a required flow-rate of an ejected gas through the gas inlet. The gas-liquid ejector unit communicates through the conical orifice of the first partition with a cavitation unit comprising a hollow cylindrical cavitation chamber having at least one tangential inlet allowing a gas-liquid mixture from a gas-liquid ejector unit to flow inside the hollow cylindrical cavitation chamber for breaking of gas bubbles and further to a jet dispersing unit through an orifice of second partition for additional dispersing and homogenization. The jet dispersing unit comprises a hollow cylindrical dispersing chamber attached to the second partition and communicates with the injection well through an outlet located at the top cover of the cylindrical housing. In addition, the hollow cylindrical dispersing chamber has at least one outlet channel and a hollow dip at the bottom of the hollow cylindrical dispersing chamber.

The present invention provides a microbial consortium containing three hyperthermophilic, barophilic, acidogenic, anaerobic bacterial strains for enhanced oil recovery from oil reservoirs where temperatures range from 70° C. to 90√ C. The said microbial consortium is unique in producing a variety of metabolic products mainly CO2, methane, biosurfactant, volatile fatty acids and alcohols in the presence of specially designed nutrient medium. These metabolic products increase sweep efficiency of crude oil from oil bearing poles of rock formation. The present invention also provides a process for enhancing the oil recovery by in situ application of the said microbial consortium.
