Steps of nitrogen removal to produce concentrated oxygen
Four steps are repeated in a cycle to remove nitrogen from the air. The blue and red arrows show the changes in the flow of pressurized air through the device in each step. This process is used in the device engineered by Professor Mahesh Bandi of the Nonlinear and Non-equilibrium Physics Unit to produce concentrated medical-grade oxygen.
In the brain, dopamine helps regulate reward and body movement. As part of the reward pathway, dopamine is produced by neurons in the ventral tegmental area (VTA) and released in the nucleus accumbens and the prefrontal cortex, leading to the feeling of pleasure. Dopamine’s role in motor functions is linked to a separate pathway: first dopamine is produced in the substantia nigra and then it’s released in the striatum. While dopamine plays the same function in each case, malfunctions in the different pathways can cause vastly different diseases such as Parkinson’s and potentially schizophrenia.
