[Effectiveness of using different types of current to determine the electrosensitivity of teeth in inferior alveolar nerve neuritis].

The Aim Of The Study: To determine the type of electric current with the greatest diagnostic value used to study the electrical sensitivity of teeth in inferior alveolar nerve neuritis.

Materials And Methods: We examined 32 patients aged from 22 to 57 years, in whom neuritis of the inferior alveolar nerve developed due to traumatic removal of the lower third molar. There were 14 females and 18 males.

A rare case of Na/Zn isomorphism in the crystal structure of acentric zincophosphate NaZn[Zn(PO)].

A microporous zincophosphate with the idealized formula NaZn[Zn(PO)] was obtained through high-temperature hydrothermal synthesis and characterized by scanning electron microscopy, microprobe analysis and X-ray diffraction. The orthorhombic compound, which crystallizes in acentric space group Pna2 with unit-cell parameters a = 12.9901 (2), b = 16.

[Surgical treatment of secondary trigeminal neuralgia].

Objective: To present a case series analysis of surgical treatment of patients with secondary trigeminal neuralgia.

Material And Methods: The treatment of 8 patients with secondary trigeminal neuralgia who underwent surgery since 2021 was analyzed. All records, neuroimaging archive, and follow-up observations were reviewed.

Rubidium vanadium(III) vanadyl(IV) phosphate, RbV(VO)(PO)(HPO): crystal chemistry and low-dimensional magnetism.

In this paper, we present the synthesis and characterization of a rubidium vanadium(III) vanadyl(IV) phosphate, obtained under hydrothermal conditions. The new compound crystallizes in the triclinic space group 1̄ with the unit cell parameters = 9.637(1), = 12.

Polyacrylonitrile Ultrafiltration Membrane for Separation of Used Engine Oil.

The separation of used engine oil (UEO) with an ultrafiltration (UF) membrane made of commercial copolymer of poly(acrylonitrile-co-methyl acrylate) (P(AN-co-MA)) has been investigated. The P(AN-co-MA) sample was characterized by using FTIR spectroscopy, C NMR spectroscopy, and XRD. The UF membrane with a mean pore size of 23 nm was fabricated by using of non-solvent-induced phase separation method-the casting solution of 13 wt.
