Flavonoids were extracted from Zizyphus spina-christi leaves by Ethyl acetate after acid digested and used as antioxidant. The dried extract was added separately to each sample of fat extracted from hallow cow and sheep bones as follows: T1 cow fat, T2 control for cow fat, T3 sheep fat and T4 control for sheep fat (the control T2 and T4 reffered to samples without added antioxidant).
Samples were stored at -18, 5, 25 and 55 °C for 28 days. The storage trials were conducted at -18, 5 and 25 °C for 28 days for T1, T2, T3 and T4. The chemical indices examined initially and at the end of storage period. PVs was 1.46, 1.46, 1.8 and 1.8 meq/ Kg oil respectively, FFA values were 0.245, 0.245, 0.244 and 0.244% respectively and TBA values were 0.015, 0.015, 0.023 and 0.023 mg malonaldehyde/ Kg oil respectively. The statistical analysis for the obtained results revealed insignificant differences (p< 0.05) among both storage periods and storage temperatures. It was also found that the added antioxidants (Zizyphus leaf) hadn't showed preservative effect on added fat samples.
The storage trial for fat samples were also conducted at 55°C for 28 days. The initial values for PVs were 1.46, 1.46, 1.8 and 1.8 meq/ kg oil respectively and the final values were 3.2, 4.4, 3.6 and 5.4 meq/ kg oil respectively. The FFAs values were initially 0.245, 0.245, 0.244 and 0.244% respectively and the final values were 0.394, 0.507, 0.451 and 0.564% respectively. The TBA values were initially 0.015, 0.015. 0.023 and 0.023 mg malonaldehyde/ kg oil respectively and the final values were 0.02, 0.032, o.o334 and o.o452 mg malonaldehyde/ kg oil respectively. The statistical analysis revealed insignificant differences p< 0.05 among storage periods for both PV and FFA values (except T1 that didn't show significant effect p< 0.05 for FFA) and TBA values. The added antioxidants (Zizyphus leaf) hadn't revealed significant effect on stored oil samples as reflected by obtained results.

This study aimed to investigate the relationship between narcissistic
personality and altruistic behavior for a subject of (307) gifted high schools
students, including (139)male and (168) female students ,both the scale of
narcissistic personality and the scale of altruistic behavior (Hameed ,2002) were
checked for its validity and reliability ,and both the level of narcissism and the
level of altruism for the students were measured in compare to the medium average
and approved to be statistically significant at (0.05) level.
Results showed that there were no significant differences in the altruistic
behavior between males and females ,results showed significant differences in
narcissism levels between males a

In this paper of mine we find that Robaayat Al khayam carries a poetic content of a special meaning in that every expression reflects semantic relationship (the good played a part in the formation lies with and the evil) of which its foundation lies with the human personality (soul), and he (the poet) a scribes it to matters of

The family is considered one of the most important social institutions which has a
strong and clear effect on the child in forming his personality through the process
of social upbringing which works on transforming the child from a merely
biological being into an individual who has customs and traditions and the behavior
of the group to which he belongs, and till now there is no social organization or
institution that can do this process not even in partial way like the family
.Therefore depriving the child of his parents leads to depriving him of the normal
chances of growth which relate to his age stage and thus this shortcoming is hard to
treat and based on the preceding the current research aimed at the follo
