Background The selfie phenomenon is an emanating one, specifically affecting adolescents and young adults. It emerges as a reflection of a wide spectrum of neuropsychiatric disorders. Based on this, the current study aimed to assess the rate of the selfie phenomenon among Egyptian university students and its sociodemographic and psychiatric correlates. During the study procedure, we enrolled 200 undergraduate Egyptian university students from two different faculties and were assessed using the Selfie Behavioral Scale, Structured Clinical Interview for DSM-IV-TR Axis I Disorders, Structured Clinical Interview for DSM-IV-TR Axis II Disorders, and Global Assessment of Functioning Scale. Results 49.5% of the students being assessed had borderline selfitis with a higher rate among females. We found a highly significant association between the selfie phenomenon and depression, anxiety, obsessive-compulsive disorder, eating disorders, and other psychiatric disorders and personality disorders, and we also found that selfies had a significant negative association with the level of functioning among students. Conclusions Results concur with previous existing literature regarding the magnitude of the selfie phenomenon and its relationship with different psychiatric disorders and personality disorders.

This simulation work is intended to describe the angular distribution of (δ) electrons in a spectrometer that is designed for simultaneously measuring gamma-rays and electrons called SAGE Spectrometer using the Geant4 simulation toolkit. The angular distributions were identified for various target materials including lead, gadolinium, tin, aluminium and carbon. In heavy ion atom collision, the direct ionization of the target elements and the scattering of electron due to the Two-Centre Coulomb forces are the dominant contributions. The direction of (δ) electrons produced in a heavy ion collision hitting a heavy element target is strongly focused in the forward and backward directions with a large suppression at perpendicular angles. For light element targets the (δ)  electrons are almost entirely forward focused. This indicates that the distributions are (Z) dependent. The main features of the (δ)  electrons coming from SAGE spectrometer are characterized by looking at their angular distributions produced from a reaction between a Ca48 ion beam and a lead target.
