  • Magnetotelluric surveys (soundings) are a naturalsource electromagnetic (EM) geophysical method that utilizes variations in the Earth’s magnetic field to image subsurface structures. A magnetotelluric sounding was attempted at Weyburn but has not produced results. Consequently, a final assessment of its utility is not available (Monea et al., 2008). Electrical resistance tomography (ERT) is a technique of imaging subsurface electrical conductivity. When deployed in time-lapse mode, it is capable of detecting conductivity changes caused by the injection of CO2.

  • The enormous consumption of antibiotics for these illnesses has contributed to the rise in antibiotic resistance among common community-acquired pathogens such as Streptococcus pneumoniae—a trend that in itself has had an enormous influence on public health.

Signs and symptoms of bacterial and viral URIs are, in fact, indistinguishable.
