Background: Mother and newborns are incredibly susceptible during the post-natal period, which is also characterized by high rates of sickness and mortality. Knowledge of post-natal care plays a crucial role in preventing these problems.Aim of the study: to evaluate the impact of health educational program for pregnant women on their selected post-partum and newborn care. Research design: quasi-experimental research design (one group pre-test, post-test) was used to fulfill the aim of this study. Sample: A purposive sample composed of 70 pregnant women was used in this research. Tool of data collection: three tools were used: Tool (I): an interviewing questionnaire. Tool (II): pregnant women's knowledge about post-partum and newborn care, Tool (III) observational checklist regarding post-partum and newborn care. Results: The findings of this study revealed that (75.70%) of the studied sample had poor knowledge level before the implementation of the educational program, while (90.00 %) of the study sample had good knowledge immediately after the implementation of the educational program and slightly decreased to (85.70%) in the first day post-partum with highly statistically significant differences which P-value ≤ 0.0001**, in addition, the results illustrated a significant improvement in total practice regarding post-partum and newborn care among pregnant women in post-test as compared to pre-test (P-value ≤ 0.0001). Conclusion: This study concluded that implementing the health education program effectively improved pregnant women's overall knowledge and practice towards postpartum and newborn care. Recommendation: Regular training programs to educate pregnant women, especially primigravida, to improve their knowledge and practice about post-partum and newborn care, which can reduce maternal and newborn morbidity and mortality.

Background: The postnatal period, especially the first few days and hours of life, is the most crucial time for both mothers and their children. To cut down on maternal and child mortality, it is crucial to implement educational programs to encourage mothers to have the right knowledge. Aim of the study: To evaluate the impact of health educational program for pregnant women on their knowledge regarding post-partum and newborn care. Research design: Quasi-experimental research design (one group pre-test, post-test) was used to fulfill the aim of this study. S ample: A purposive sample of (70 pregnant women) was used in this research. Two tools were used for data collection: Tool (I) interviewing questionnaire. Tool (II): Pregnant women's knowledge about post-partum and newborn care. Results:The findings of this study revealed that (75.70%) of the studied sample had a poor knowledge level before the implementation of the educational while (90.00%) of the study sample had good knowledge immediately after the implementation of the educational program and slightly decreased to (85.70%) in the first day post-partum with highly statistically significant differences. Conclusion: Implementation of the health education program was effective and significantly improved pregnant women, overall knowledge towards post-partum and newborn care. Recommendation: Regular training programs to educate pregnant women, especially primigravida, to improve their knowledge about post-partum and newborn care which can reduce maternal and newborn morbidity and mortality.

The complexation of the divalent transition metal ions Zn (II), Pb (II) or Cd (II) with two important biologically zwitterionic buffers (N-[2-hydroxyethyl] piperazine-N'-[2ethanesulfonic acid]) (HEPES) and (N-[2-hydroxyethyl] piperazine-N'-[2-hydroxypropanesulfonic acid]) (HEPPSO) in an aqueous medium, were studied using potentiometric pH titration in 1:1 ratio at four different temperatures 288 K, 298 K, 308 K and 318 K at ionic strength 0.1 molL-1 KNO3. The formation constants and thermodynamic parameters of different protonated, normal, monohydroxy and dihydroxy complexes for the binary systems M(II) + HEPES and M(II) + HEPPSO have been evaluated. The electrochemical behavior of the free Pb(II) and its binary complexes with HEPES and HEPPSO was studied by cyclic voltammetry on glassy carbon electrode. Upon temperature elevation the rate of the reduction process of the Pb 2+-HEPPSO is higher than that of Pb 2+-HEPES. The diffusion coefficient, the activation energies and the standard rate constant (Ks) for the diffusion process of Pb(II) complexes were calculated.
