To investigate the molecular basis of β -thalassemia intermedia in Northern Iraq and evaluate its management practices, a total of 74 patients from 51 families were enrolled. The patients were clinically and hematologically reevaluated, and had their β-thalassemia mutations characterized, as well as the number of α-globin genes and Xmn I (G)γ-158 (C>T) polymorphism studied. Out of 14 β-thalasse...

Both X-ray absorption and diffraction techniques were used to study the structural environment and oxidation state of Mn in goethite-groutite solid solutions, α-MnxFe1–xOOH, with xMn ≤ 0.47. Rietveld refinement of X-ray diffraction (XRD) data was employed to investigate the statistical long-range structure. The results suggest that increasing xMn leads to a gradual elongation of Fe and Mn occup...

Throughout, w, Γ, and∧ denote the classes of all, entire, and analytic scalar-valued single sequences, respectively. We write w2 for the set of all complex sequences (xmn), where m,n ∈ N is the set of positive integers. Then, w2 is a linear space under the coordinatewise addition and scalar multiplication. Some initial works on double sequence spaces are found in Bromwich [1]. Later on, they we...

This research is focused on increasing the reliability of Fe-11Al-Mn by combining properties Mn and superiority Fe-Al-C under cryogenic temperature. Three alloys with compositions 15 wt % (F15), 20 (F20), 25 (F25) were investigated. The process uses liquid nitrogen in a temperature range 0–196 °C. Hardness testing using Vickers method SEM was used to analyze microstructure. X-ray diffraction (X...

The synthesis of (Ba0.99Ca0.01)(Zr0.2Ti0.8)O3 (BCZT) and doped (Ba0.99Ca0.01)(Zr0.2Ti0.8-xMnx)O3 (BCZT-xMn) ceramics was successfully carried out by the solid-state method. doping effect is followed X-ray powder diffraction, scanning electron microscopy (SEM), dielectric conductivity measurements. Indeed, diffraction measurements show crystalline structure ceramics. SEM images indicate on studi...

The extruded Mg-6Li-4Zn-xMn (x = 0, 0.4, 0.8, 1.2 wt%) alloys were prepared, and the microstructure of test was investigated by optical microscopy, scanning electron microscopy transmission microscopy. corrosion properties determined electrochemical measurements immersion in 3.5% NaCl solution. results indicate that are mainly composed α-Mg phase, β-Li Mn precipitates some intermetallic compoun...
