ABSTRACT Ethics in social work will be the extension of the philosophical work in the welfare discipline known as social work. The transformation of social work as a profession flows from the pleadings of social philosophy for a deeper humanitariannization and valuation of social work.

ABSTRACT This work has investigated the effect of austempering variables on hardness, strength and toughness of 0.48wt. % calcium treated cast iron. The iron was subjected to varying austenitizing and isothermal transformation temperatures and times. Samples were austenitized for 15, 30, 45 and 60 minutes at each of the temperatures 850, 875, 900, 925 and 950 degrees centigrade. Also for 950℃ and 60 minutes of austenitizing conditions, samples of the 0.48wt. % calcium treated irons were isothermally ...

ABSTRACT Fingerprints are a unique feature for identification and verification of humans. The need to optimise several databases for storing the images of fingerprints is a major concerning issue. Several segmentation algorithms have been used in the time past but there are still several challenges facing some current segmentation algorithms like computational efficiency. Another challenge is that segmentation procedure can be impractically slow...
