Corona discharge the electron-liberation is a high-energy photon from an atom within the plasma body relaxing after excitation from an earlier collision. The use of ionized neutral gas as a source of ionization is further diminished in a negative corona by the high-concentration of positive ions clustering around the curved electrode. Under other conditions, the collision of the positive species with the curved electrode can also cause electron liberation. The difference, then, between positive and negative coronas, in the matter of the generation of secondary electron avalanches, is that in a positive corona they are generated by the gas surrounding the plasma
Negative and positive atheism atheism as a way of life in his 1972 book, "Positive Atheism". Similarly, the Atheist Community of Austin (ACA) uses the term "positive atheism" in the sense of putting a positive face to atheism and dispelling the false and negative image of atheism portrayed by religious people, especially in places of worship. "Positive Atheism Magazine" "sees atheism as being a positive, healthy outlook -- much healthier than any theistic approach to life." Agnostics are not always merely implicit atheists.
