The pure spinel phase of Ni0.45Co0.2Zn0.35F2O4 was prepared by coprecipitation method and ceramic method. The nanocomposite [(NCZF)1–x(Na(***))x] (x = 0%, 20%, 40%, 60%, 80%, 100%) was prepared by mixing two phases, Ni0.45Co0.2Zn0.35F2O4 with coprecipitation method [NCZF] and sodium acetylacetonate [Na(***)]. The TEM photographs of the as prepared ferrite samples by coprecipitation method at different ratios of Na(***) show that the crystalline cubic nanoparticles diameter were ranged from 26 - 36 nm and the particle size of Na(***) is greater than NCZF. The same behavior has also confirmed by XRD pat-terns indicating polycrystalline nature of prepared sample. The comparison between the SEM micrographs for NCZF nanoparticles prepared by a) ceramic method and b) co-precipitation method was done to show the effect of preparation condition on the microstructure. IR analysis confirms the composites formation.

NEW CONTRIBUTION TO ThE MIOCENE BIOSTRATIGRAPhY OF NORTh SIWA OASIS (GEBEL ZEITUN), WESTERN DESERT, EGYPT

International Conference on Industrial Technology and Management Science(ITMS 2015)

Sanyangzhuang settlement sites is a ancient villages, which are flooded by the Yellow River in early Western han Dynasty. A large number of pottery tiles as a part of ancient villages excavated from Sanyangzhuang sites has great value in the study of early Chinese village building. In order to preserved those well, we analyzed the properties of pottery tile by XRD（X-ray diffraction）, ESEM（Environment scanning electron microscope） and Electronics omnipotent material trial instrument for the component, structure and mechanical. The results shown that the pottery tile’s main ingredients is silicide with loose structure, low mechanical strength and high salt content, which is main reasons for pottery tile weather.

Electric and Magnetic Properties of [(NCZF)1-x(Na(***))x] Nanocomposite

第二届国际古生物学大会

作者： A.SADEK sh.SADEK Cairo University Egypt

Gebel Zeitun is located 8 km to the north of Siwa Oasis and was previously assigned a Middle Miocene age. It is represented by the well-known Marmarica Formation. For the first time in Egypt the present study shows that the basal part of the Marmarica Formation belongs to the Early Miocene based on the occurrence of the global calcareous nannoplankton fossils, helicosphaera ampliaperta and h. scissura of Burdigalian age. The upper part of the studied section yielded a rich association of the Borelis melo group of the Middle Miocene. A biostratigraphical zonation is proposed by the present writers for the Miocene strata in the studied

The pure spinel phase of Ni0.45Co0.2Zn0.35F2O4[NCZF] was prepared by co-precipitation method. The nanocomposite [(NCZF)1-x(Na(***))x] (x = 0%, 20%, 40%, 60%, 80%, 100%) was prepared by mixing two phases: ferrite phase and ferroelectric phase. The magnetic characters of compo-sites performed using vibrating sample magnitude (VSM) at room temper-ature with maximum applied field up to 2 kG. For smaller particle size 30.89 nm. The saturation magnetization Ms decreases linearly with increasing particle size. The effect of temperature on the electrical resistivity of the different composites samples was studied. It is noted that, the resistivity decreases with rising temperature to have a minimum value at ferroelectric transition temperature, above this value the resistivity increases. The dielectric constant increases with increasing temperature for all composites. The dielectric loss tan (δ) as a function of temperature sharply with temperature reached to maximum value at ferroelectric phase transition then decrease again.

Background: Sustained lung inflation (SLI) would permit lung recruitment immediately after birth, improving lung mechanics and reducing the need for intubation and subsequent respiratory support in the neonatal intensive care unit among preterm infants. Aim of the Study: To assess the efficacy of initial sustained lung inflation compared to standard intermittent positive pressure ventilation (IPPV) in preterm infants who need resuscitation in delivery room. Methods: This was prospective randomized observational study that was conducted in the delivery room and NICU of A in shames University hospital from February 2019 to September 2019. The study included 115 preterm infants between 26 - 32 weeks of gestation who needed resuscitation at delivery room. The infants were randomly allocated into 2 groups;SLI group: included the preterm infants who received the SLI at initial inflation pressure of 25 cm H2O for 15 seconds using the Neopuff/T piece. IPPV group: preterm infants who received standard resuscitation;IPPV using the self-inflating bag
