In the present work, the non-inverted (isothermal) type equations of state (EOS) which are based on interionic potential such as Vinet–Rydberg EOS, Shanker EOS, Bardeen EOS as well as Kumar isothermal EOS are used to study ...

The polyhydroxyl-polyurethane foam (PPF) was used as a new sorbent for separation, preconcentration and determination of manganese and iron ions in natural samples. Experimental conditions for effective separation of trace ...

Ionizing radiation of polymers is a promising technique that has found applications in various fields such as food preservation, pharmaceutical production and natural bioactive agent industries. Irradiation technology has ...

A mathematical model which describes the quasistatic frictional contact between a piezoelectric body and a deformable foundation is studied in this paper. A nonlinear electro-viscoelastic constitutive law is used to model ...

In this work we investigate the constrained motion of a particle on an ellipse in the framework of two approaches: the standard approach and Dirac’s approach. The Poisson brackets and the Dirac brackets of the generalized ...

The study was conducted to evaluate anti-tumor (human cervical cancer; HeLa and Rhabdomyosarcoma; RD cell lines and a primary cell culture; mouse embryo fibroblast; MEF) potentials of Agrimonia eupatoria L. extracts (aqueous ...

This work deals with the preparation of a new tetradentate ligand [ H2L] of the N2O2 type, N{2[3(1-carboxyiminoethyl)-1-phenyl]butilydene-2-amino propionic acid}, and its metal complexes with Cr(III), Fe(III), Cu(II) and ...
