for a fixed positive integer , we say a ring with identity is n-generalized right principally quasi-baer, if for any principal right ideal of , the right annihilator of is generated by an idempotent. this class of rings includes the right principally quasi-baer rings and hence all prime rings. a certain n-generalized principally quasi-baer subring of the matrix ring are studied, and connections...

In act theory, Pseudo injective acts and their generalizations are essential. As a result, the purpose of this work is to give generalization pseudo quasi principally specifically small acts. Besides, concept was presented, which can be employed later. If each S-monomorphism from M-cyclic sub-act M\textsubscript{S} N\textsubscript{S} extended S-homomorphism N\textsubscript{S}, An S-act called p...

This paper models damage induced by monochromatized Al Ka X-rays to organic thin films using self-assembled monolayers supported on Al, Ti, Cu, and Au. An X-ray photoelectron spectrometer is used both to conduct the X-ray irradiation and to analyze the damage. In all cases these monolayers comprised a trifluoroacetimido (CF3CONH-) group bound to the substrate through an undecyl tether to either...
