An efficient and convenient synthesis of novel tetrahydrobenzo[c]acridin-8(7H)-one derivatives is described using the electrogenerated anion of acetonitriles as the base in the presence of tetrabutylammonium fluoride as an effective supporting electrolyte in a one-pot, three-component condensation of aromatic aldehyde, dimedone and 1-naphthyl amine. The reaction is carried out in an undivided c...

We present an assessment of the effect of rotational losses on an induction machine. The assessment provides an estimate of the iron losses in an induction machine by three methods, all of which rely on the output data of a two-dimensional finite-element method: 1) calculating iron losses as if they were produced by a purely alternating field; 2) calculating the iron losses by adding the losses...

nowadays, magnesia carbon refractories are very important for the iron and steel industries. it is dueto their unique properties, such as low wet ability with melt iron and steel. therefore, it is importantto extend the life of the refractory. in this research, the effect of calcined alumina and nano carbon onmechanical strength and corrosion resistance against slag in magnesia carbon refractor...

We calculate the efficiency of iron K line emission and iron K absorption in photoionized models using a new set of atomic data. These data are more comprehensive than those previously applied to the modeling of iron K lines from photoionized gases, and allow us to systematically examine the behavior of the properties of line emission and absorption as a function of the ionization parameter, de...

Background: Iron deficiency, is a common worldwide complication, especially in preschool children. Iron deficiency anemia (IDA) is associated with changes in the mental and motor development, defects of immune system, cardiovascular, diseases and disruption of lipid profile. In IDA, the occurrence of dyslipidemia is controversial. We aimed to investigate the association between IDA and serum li...

Electrochemically generated iron can remove most contaminants present in water and wast water, by precipitation, adsorption, electrostatic interaction, and complex formation (generally called electrocoagulation-EC). In the present paper, pretreatment of brackish water having high total hardness (TH), alkalinity (A),  and Cl¯ ions, is studied by application of a DC-electrical current ot the ...

The composition and the structure of the Earth's solid inner core are still unknown. Iron is accepted to be the main component of the core. Lately, the body-centered cubic (bcc) phase of iron was suggested to be present in the inner core, although its stability at core conditions is still in discussion. The higher density of pure iron compared with that of the Earth's core indicates the presenc...

In the present study electrocoagulation (EC) has been evaluated as a treatment technology for arsenite [As(III)] and arsenate [As(V)] removal from water. Laboratory scale experiments were conducted with three electrode materials namely, iron, aluminum and titanium to assess their efficiency. Arsenic removal obtained was highest with iron electrodes. EC was able to bring down aqueous phase arsen...
