identifying the chain of transmitters mentioned in the sanads for the verification of the sanad is necessary for employment of ḥadīth. one of the problems observed in the chains of transmission is the repetition of the names applicable to two or more transmitters. on the other hands, some transmitters have been referred to by various names and titles in chains of transmission; various titles th...
Objective: Zirconia cores have limited light transmittance and data are scarce on light transmission through zirconia cores with and without the veneering ceramic. Methods: In this in vitro study, Disc-shaped specimens (11.5 mm in diameter and 0.4 (0.05) mm in thickness) were fabricated of three types of zirconia namely Mamut, Heany and ZirkonZahn (n=5). A disc-shaped specimen (11.5 mm in d...
This paper presents an efficient method based on bus power injection for transmission line compensation. In this method, the load flow solution is first obtained using specified generations and loads. The terminal buses connecting the line to be compensated and the compensation level are identified. The differences of the line flows before and after compensation are injected in or out of the tw...
