Cyanobacteria (blue-green algae) are Gram-negative photosynthetic eubacteria that are
found everywhere. This largest group of photosynthetic prokaryotes is rich in structurally …

Rough surfaces possess complex topographies, which cannot be characterized by a single
parameter. The selection of appropriate roughness parameters depends on a particular …

At present research, we highlight ultrasonic treatment as a new way to create materials with
a gradient change of chemical or physical properties. We demonstrate the possibility to …

The mathematical method of separation of motions represents the effect of fast high-
frequency oscillations by an effective averaged force or potential. Ultrasound acoustic …

Polished brass alloy plate samples were treated by ultrasound in an alkaline buffer at
different concentrations and sonication amplitudes. Sample topography was studied by …

Periodically driven thermodynamic systems support stable nonequilibrium oscillating states
with properties drastically different from equilibrium. They exhibit even more exotic features …

Bacteria affect food quality in develo** countries by spreading through contaminated soils
and water. Antibiotics are used indiscriminately to eliminate Gram-positive and Gram …

Проблема антибиотикорезистентности стала особенно актуальной в XXI веке.
Устойчивость к антибиотикам прогнозируется как одна из самых больших угроз …
