This work reviews the present position of and surveys future perspectives in physics chaotic advection: field that emerged three decades ago at intersection fluid mechanics nonlinear dynamics, which encompasses a range applications with length scales ranging from micrometers to hundreds kilometers, including systems as diverse mixing thermal processing viscous fluids, microfluidics, biological flows, oceanographic atmospheric flows.
The gas-sensitive properties of the forward SH1 and backward A1 acoustic waves in YX lithium niobate plate loaded with a biofilm based on mycelium higher fungi are considered. possibility using an acoustoelectronic device single interdigital transducer (IDT) as element is shown. In absence sensor coating surface piezoelectric plate, S11 parameter above does not change when exposed to water vapor, ethanol acetone range from 7 20 MHz. When film basidiomycetes applied side free IDT, wave...
New models and properties of forced oscillations the various physical systems (pendulum piezoceramic transducer) due to interaction with excitation device limited power-supply are investigated in details. Using an analysis largest Lyapunov exponent for a complicated system—vibrating subsystem exciter—the regions three steady state regimes determined, namely: stationary, periodic chaotic.
The influence of humidity on the density, shear elastic module, viscosity, and thickness mushroom Pleurotus eryngii Ganoderma lucidum mycelium films was studied. These data were obtained by comparing theoretical experimental frequency dependencies complex electrical impedance bulk acoustic wave (BAW) resonator loaded film using least-squares method. This procedure performed for BAW with pointed relative range 17%–56% at room temperature. As a result, changes under study, due to water vapor...
Ganoderma lucidum exhibits the ability to synthesize a diverse range of biologically active molecules with significant pharmaceutical potential, including xylomannan and fucogalactan, which have demonstrated antitumor activity. However, there exists considerable intra-species variability in capacity produce these metabolites at high concentrations, likely reflecting genomic diversity observed from limited number strains sequenced date. We employed high-throughput shotgun sequencing obtain...
Interactions between the oscillations of piezoceramic transducer and mechanism its excitation—the generator electric current limited power-supply—are analyzed in this paper. In practical situations, dynamics forcing function on a vibrating system cannot be considered as given priori, it must taken consequence whole system. other words, source has power, that provided by dc motor for an example, thus own is influenced being forced. This increases number degrees freedom problem, called...
The present article describes the development of media for high-yield cultivation medicinal mushrooms Hypsizygus marmoreus and H. ulmarius results in vivo investigations into antitumor activity water extracts mycelia both species total polysaccharide fraction ulmarius. were optimized using statistical experimental design methodologies, including full factorial steepest ascent. yield amounted to 32-33 g/L air-dried biomass on 3rd 4th day cultivation. corresponding figures two strains...
The paper describes a method for determining the properties of thin films: elastic constants, viscosity and density. is based on analysis changing characteristics acoustic resonator, surface which film under study deposited, in comparison with free resonator. Using described method, two organic films mycelium basidiomycete Hericium erinaceus (Bull.) Persoon were determined.
A comparative analysis of the responses two types acoustic waves (surface SAW and plate APW) with close frequencies same type (SAW) different toward various liquid vapors (water, acetone, ethanol) was carried out in this paper. Two films based on mycelium higher fungus Ganoderma lucidum (Curtis) P. Karst (G. lucidum) prepared by methods were used as sensitive coatings. These G. ethanolic (48% v/v) homogenizate (MEGl) extract (EGl). film deposition procedure compatible devices technology...
We studied free surface oscillations of a fluid in cylinder tank excited by an electric motor with limited power supply. investigated the possibility parametric resonance this system, showing that excitation mechanism can generate chaotic response. Numerical experiments are carried out to present existence several types regular and attractors. For first time powers (power motor, consumed damping force under oscillations, total power) calculated, investigated, shown for different regimes,...
Background. Basidiomycetes have high biosynthetic capabilities. Their metabolites are capable of exhibiting antimicrobial properties, thereby being promising molecules for use in medicine or further chemical transformation. The aim the work. Evaluation antibacterial and antifungal properties culture liquid basidiomycetes from orders Agaricales Polyporales, selection active strains research. Materials methods. objects study were 10 species Polyporales. Filtrates liquids obtained as a result...
A synthesis of nanosized hydroxyapatite by the exchange reaction between diammonium phosphate and calcium nitrate under conditions mechano-acoustic processing mixture was developed.Methods are proposed for purifying from by-products.By dispersing raw materials animal origin, a protein hydrosol obtained in medium which synthesized collagen-calcium-phosphate composite obtained.Methods formation porous composites, among effect microwave radiation, considered.It is shown that based on developed...
Based on the assessment of trophic needs basidiomycete Flammulina velutipes and optimization composition nutrient medium using design experimental approach, yield submerged biomass fungus was increased to 41 g/L, duration cultivation process reduced 5 days. For this purpose, 24 full factorial design, Box–Wilson steep ascent method construction response surface were used. Using scanning electron microscopy, it shown that studied F. strain grew in form small spherical pellets with a diameter...
