Abstract: A method of extracting viable bacterial cells from a soil sample by mixing a dispersant-surfactant solution with a soil sample to form a soil slurry, adding the soil slurry to a centrifuge tube containing a density gradient medium, centrifuging the centrifuge tube to form a solvent layer above the density gradient medium, wherein the solvent layer comprises viable bacterial cells, extracting the solvent layer containing the viable bacterial cells, combining the extracted solvent layer with a PBS solution to form a PBS-cell mixture, filtering the PBS-cell mixture to form a cell filtrate, depositing the cell filtrate into a second centrifuge tube containing a quantity of the density gradient medium, centrifuging the second centrifuge tube to form a second solvent layer comprising the viable bacterial cells, and extracting the second solvent layer from the second centrifuge medium to form a second cell filtrate comprising the viable bacterial cells.

Abstract: A probe is described. The probe includes a probe antenna, a transmitter, a receiver and circuitry including hardware. The probe antenna is constructed of a dielectric material connected to a waveguide, the probe antenna has a far field region. The transmitter is coupled to the probe antenna. The receiver is coupled to the probe antenna. The hardware is configured to communicate with the transmitter to enable the transmitter to direct a pulse of electromagnetic energy to the probe antenna and to receive a reflection signal from the receiver, the hardware is configured to determine a material property of a material within the far-field region of the probe antenna by analyzing the reflection signal.

Abstract: A double skin façade (DSF) for a building is disclosed. The DSF has a first façade, a second façade, and a gap extending therebetween. Movement of air is driven in an upward direction toward an upper end of the DSF, causing movement of air contaminants from a lower end of the DSF to the upper end of the DSF, and thereby enhancing the air quality of the street canyon by removing air contaminants from a street level adjacent the building. Also disclosed is a building having a DSF, and a method of enhancing air quality in a street canyon by constructing a DSF on a building.
