Abundances in planetary nebulae: NGC1535, NGC6629, He2-108, and Tc1 [PDF]

, 2011
The aim of the paper is to determine abundances in a group of PNe with uniform morphology. The PNe discussed are circular excited by rather low-temperature central stars. The relation between abundance and evolution is discussed. The mid-infrared spectra

Different dissociation and alexithymia domains specifically relate to patients with psychogenic non-epileptic seizures (PNES) and with PNES and comorbid epilepsy (PNES+EP)

Journal of Affective Disorders Reports, 2022
Background: Several studies previously examined the role of dissociation and alexithymia in patients with psychogenic non-epileptic seizures (PNES). However, their relationship remains unclear. Methods: We administered questionnaires for dissociation (DES-II), alexithymia (TAS-20), anxiety and depression to 57 subjects: 14 patients with PNES, 13 ...
