Mononuclear and icosanuclear spin-crossover complexes, [Fe] [Fe 20 ], were synthesized. has a bis-chelate structure, while ] ring-shape structure comprising four [2 × 2] grid moieties mononuclear units.

This paper describes a new shape of an aluminum ring that can be suspended magnetically by the AC ampere maglev method. method uses first magnetomotive source and second with same frequency appropriate phase difference. The magnetic flux from these sources acts on highly conducting object to generate electromagnetic force. allows specific (a single (Al) ring) pulled up vertically against gravit...

Mechanisms of resource allocation are essential for maternal and fetal survival, particularly when the availability of nutrients is limited. We investigated the responses of feto-placental development to maternal chronic protein malnutrition to test the hypothesis that maternal low protein diet produces differential growth restriction of placental and fetal tissues, and adaptive changes in the ...

background: infection with parvovirus b19 may cause fetal losses including spontaneous abortion, intrauterine fetal death and non-immune hydropsfetalis. the aim of this study is to determine the frequency of parvovirus b19 in formalin fixed placental tissues in lost fetuses using real-time pcr method.   methods : in this cross-sectional study, 100 formalin fixed placental tissues with unknown c...

Background The metabolic enhancement resulted from hyperglycemia in gestational diabetes leads to macrosomia, which can affect the placenta. In gestational diabetes mellitus (GDM) pregnant women, the thickness of placenta and cord diameter can change at ages prior to treatment initiation. Therefore, this study was conducted to examine the thickness of placenta an...
