Cotton hanks were dyed with three different sulphur dyes using non-sulphide reducing agents such as glucose, fructose, invert sugar and molasses. The alkalies employed for reduction were sodium carbonate and sodium hydroxide. Invert sugar as a reducing agent and sodium carbonate as alkali proved to be better as this combination gave results comparable to those obtained with the conventional sod...

The chemical process of iron reduction from magnetite by gaseous reducing agents is the basis MIDREX technology implemented at Oskol Electrometallurgical Plant (OEMK). In paper, this was modeled using TERRA software package developed Bauman Moscow State Technical University. During simulation, thermodynamic system Fe‒С‒О‒Н analyzed constant temperature (900 °C) and gas pressure (0.2026 MPa). Mi...

Utilizing resources focused on artificial intelligence (A.I.) and its influence education, this paper analyzes the impact of “animated agents” to aid students in learning understanding a new language. We used these articles understand effect that A.I. has anxiety levels how learners respond differing motivational agents. Foreign Language Anxiety (FLA) is term describe stress exhibited by langua...

The preparation of a series of homoleptic, four-coordinate lanthanide(ii) complexes, [Ln(Priso)(2)] (Ln = Sm, Eu or Yb) incorporating the bulky guanidinate ligand Priso(-) ([(ArN)(2)CNPr(i)(2)](-), Ar = 2,6-diisopropylphenyl) is described. X-ray crystallography shows the complexes to be isostructural and to exhibit coordination geometries midway between tetrahedral and planar. Comparisons betwe...
