The problem of spectral description of the nonlinear capillary waves on the fluid surface is discussed.Usually, three-wave nonlinear interactions are considered as a major factor determined by the energy spectrum of these waves in asus vivobook r565ea the kinetic wave turbulent regime.We demonstrate that four-wave interactions should be taken into
Anaerobic digestion produces biogas which usually contains 60-70% of methane (CH4), 30-40% of carbon-di-oxide (CO2), and 10-2,000 ppm hydrogen sulfide (H2S).The concentration of H2S depends upon the type of substrate.H2S tends to corrode pipes and machines carrying them.The high concentrations of H2S present in biogas may adversely affect electrici
Volcanic eruptions comprise an important airborne hazard for aviation.Although significant five finger death punch a decade of destruction events are rare, e.g.compared to the threat of thunderstorms, they have a very high impact.The current state of tools and abilities to mitigate aviation hazards associated with an assumed volcanic cloud was test
Mucosal surfaces in the gastrointestinal tract are continually exposed to native, commensal antigens and susceptible to foreign, infectious antigens.Immunoglobulin A (IgA) provides dual humoral responses that create a symbiotic environment for fr9967 the resident gut microbiota and prevent the invasion of enteric pathogens.This review features rece
