Plasma medicine Plasma medicine Plasma medicine is an emerging field that combines plasma physics, life sciences and clinical medicine. It is being studied in disinfection, healing, and cancer. Most of the research is in vitro and in animal models. It uses ionized gas (physical plasma) for medical uses or dental applications . Plasma, often called the fourth state of matter, is an ionized gas containing positive ions and negative ions or electrons, but is approximately charge neutral on the whole. The plasma sources used for plasma medicine are generally low temperature plasmas, and they generate ions, chemically reactive atoms and molecules, and
Positive and Negative Affect Schedule between the two. Previous mood scales for children have been shown to reliably capture the former relationship but not the latter; the PANAS-C was created as a tool with better discriminant validity for child assessment. Similar to the development of the original PANAS, the PANAS-C drew from terms of the PANAS-X and eliminated several terms with insufficient correlations between the term and the affective construct after preliminary analyses with a non-clinical sample of children. The final version of the measure consists of 27 items: 12 positive affect terms and 15 negative affect terms. Despite the purpose of its development, however,
