Variations in geomagnetic reversal frequency during the Earth's middle age

Low frequency geomagnetic field variations at Dome C (Antarctica)

We conduct an analysis of the geomagnetic field variations recorded at the new Antarctic station Dome C, located very close to the geomagnetic pole, which has been operating for approximately one month during the 1999–2000 campaign. We also perform a comparison with simultaneous measurements at the Italian Antarctic station Terra Nova Bay, in order to investigate the spatial extension of the ph...

Geomagnetic reversal through critical models

Geomagnetic polarity reversal intervals display power law distribution functions, which indicate a critical phenomenon as the mechanism of their source. The geodynamo is assumed to be a system of magnetic spins in a critical phase-transition state. Seki and Ito developed two models to simulate these reversals: the N-disc coupled model and the Coupled map lattice model both derived from the Riki...

The geomagnetic field variations and earthquake activity

the effect of e-64 on the developmental competence of sheep cocs during in vitro maturation

in the present study, the effect of e-64 at different concentrations (0.5, 1, 5 and 10 µm) added to (1) the ivm medium on oocyte nuclear maturation and developmental competence of ovine oocytes, and (2) to the ivc medium on embryonic development of ovine embryos were investigated.

Assessing the frequency of cytomegalovirus in the small for gestational age neonates in Al-Zahra hospital during 2015-2016.

Introduction: Congenital cytomegalovirus (CMV) infection is the most common intrauterine infection, and while many women of reproductive age are CMV-positive, neonates born to these mothers can be asymptomatic, but they can be in later years with permanent and progressive effects, hearing loss is the main side effect. So, early detection and treatment can prevent its progress.  On the other han...
