Abstract Nanocomposites containing different contributions of vanadium oxide (V 2 O 5 ) and magnetite (Fe 3 4 modified with manganese (Mn) ions were fabricated upon the formula xMn 0.4 Fe 2.6 /(1-x)V 5, whereas x = 0.0, 0.2, 0.4, 0.5, 0.6, 0.8, 1.0. The obtained compositions characterized their structure, morphology, besides magnetic susceptibility. TEM micrographs depicted that V was formed as...

Mg has been considered a promising biomaterial for bone implants. However, the poor corrosion resistance has become its main undesirable property. In this study, both alloying Mn and laser-melting were applied to enhance the Mg corrosion resistance. The corrosion resistance, mechanical properties, and microstructure of rapid laser-melted Mg-xMn (x = 0-3 wt %) alloys were investigated. The alloy...

BACKGROUND FMH quantification is necessary to calculate an individual dose of prophylactic anti-RhD immunoglobulin and to diagnose fetal anaemia causes. We encountered a healthy woman with a numerous RBCs containing fetal haemoglobin (HbF). AIMS To investigate the cause of this sign and the correct evaluation of fetal RBCs in maternal circulation. MATERIALS AND METHODS Patients samples and ...

The γ(G)-158 (C→T) polymorphism plays important function in the disease severity of sickle cell anemia. The XmnI restriction site at -158 position of the γ(G)-gene is associated with increased expression of the γ(G)-globin gene and higher production of HbF. This study aims to determine the frequency of the different genotypes of the γ(G) Xmn I polymorphism in sickle cell anemia and sickle cell ...

We study the volatility of the output of a Boolean function when the input bits undergo a natural dynamics. For n = 1, 2, . . ., let fn : {0, 1}mn → {0, 1} be a Boolean function and X(n)(t) = (X1(t), . . . , Xmn(t))t∈[0,∞) be a vector of i.i.d. stationary continuous time Markov chains on {0, 1} that jump from 0 to 1 with rate pn ∈ [0, 1] and from 1 to 0 with rate qn = 1−pn. Our object of study ...
