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...

Playwriting guides, creative writing handbooks, and screenwriting manuals are replete with guidance as to how an author should express their themes. One common rule of thumb is that the climax where themes, characters, narrative’s result converge in terminal thematic statement. If theme established elaborated on during a film, then its film’s authors position matter through or lack thereof. As ...
