in this thesis, phosphorus ylides [phbppy], [no2bppy] and [brbppy] have been synthesized through the formation of phosphonium salt and dihydrogenation, followed by the reaction of pd(oac)2 and the orthopalladated dinuclear complexes [pd(?-cl)(phbppy)]2, [pd(?-cl)(no2bppy)]2 and [pd(?-cl)(brbppy)]2 have been produced. the reaction of dinuclear complexes and bidentate ligands [l = bipy (2,2-bipyr...
Some reproduction characteristics of keeled mullet, Liza klunzingeri, were studied during Apr. 2003 to Feb. 2004 in Khuzestan waters of the Persian Gulf. A total of 836 samples were monthly collected from two fish landings of Bahrekan and Hendijan; 727 specimens were studied from point of sex determination, and 60 specimens were studied from the fecundity point of view. This species was found ...

It is rarely reported that collinear antiferromagnetic (AFM) metals can exhibit the anomalous Hall effect (AHE). In this Letter, based on symmetry analysis and first-principles electronic structure calculations, we predict two existing antiferromagnets ${\mathrm{Nb}}_{2}{\mathrm{FeB}}_{2}$ ${\mathrm{Ta}}_{2}{\mathrm{FeB}}_{2}$, whose N\'eel temperatures are above room temperature, have a very l...
