In the title compound, C21H15BrO, there are two planar rings connected through a conjugated double bond.As it crystallizes in a non-centrosymmetric space group it can be regarded as a good candidate for non-linear optical applications.The molecule Fridge Water Inlet Valve adopts an E configuration and the C—C=C—C torsion angle i

Emerging evidence confirms COVID-19’s negative impact on college students’ mental health; however, more research is needed to identify factors that promoted or hindered college students’ mental health early in the 20m Coaxial pandemic.This exploratory study addressed this need.Participants were 697 students attending a large, state, urban uni

Constructing a relativistic quantum mechanics (RQM) for a massive photon, without appealing to the quantum field theoretical approach such as the massive Proca model, we find a new theoretical particle solution which allows the massive photon having either positive or negative energy as solutions.In particular, we predict the existence of the so-ca
