Metallic foreign bodies of brain ventricles.

Unlabelled: Head injuries are often associated with intracranial foreign bodies that require decision making on the need for certain surgical treatment. Intraventricular foreign bodies are rare, so the question of surgical tactics is still open.

Objective: To summarize the experience of treating the wounded with intraventricular foreign bodies.

A Model Procedure for Catalytic Conversion of Waste Cotton into Useful Chemicals.

Cotton is grown in about 90 countries and accounts for 24% of the fibers used in the global production of textiles. In 2018/2019, 25.8 Mt of cotton were produced around the world.

[Cysts of septum pellucidum, cavum vergae and cavum veli interpositi. Meta-analysis of 368 cases].

Objective: To review and systematize literature data on the incidence of cysts of septum pellucidum, cavum vergae and cavum veli interpositi, their clinical manifestations, indications for surgical treatment and optimal surgical approach.

Material And Methods: An analysis included 72 manuscripts devoted to epidemiology, pathophysiology, clinical symptoms and results of surgical treatment of brain cysts. Case reports, series of cases, reviews and original studies were analyzed.

Nanofibrous TiO produced using alternating field electrospinning of titanium alkoxide precursors: crystallization and phase development.

High-yield, free-surface alternating field electrospinning (AFES) was effectively used in the fabrication of titanium oxide nanofibrous materials from the precursors based on titanium alkoxide and a blend of polyvinylpyrrolidone and hydroxypropyl cellulose. The alkoxide/polymer mass ratio in the precursor solution has significant effects on the precursor fiber production rate as well as the structure of resulting TiO nanofibers after thermal processing of precursor fibers at temperatures from 500 to 1000 °C. Within the range of tested process parameters, the best fiber production rate of ∼5.

Fabrication of dual-functional composite yarns with a nanofibrous envelope using high throughput AC needleless and collectorless electrospinning.

Nanotechnologies allow the production of yarns containing nanofibres for use in composites, membranes and biomedical materials. Composite yarns with a conventional thread core for mechanical strength and a nanofibrous envelope for functionality, e.g.
