Abstract Background In most arthropods, adult females are larger than males, and male competition is a race to quickly locate and mate with scattered females (scramble competition polygyny).Variation in body size among males may confer advantages that depend on context.Smaller males may be favored due to more efficient locomotion leading to higher
Abstract To suppress the significant vibration line spectra of piping systems under multi-frequency harmonic excitations, a novel dynamic vibration absorber (NDVA) is designed.The NDVA integrates numerous independent resonant units within a finite space through an ingenious structural design and possesses rich frequency regulation characteristics.A
The purpose of the studies was to determine the microorganisms communities in the soil under scorzonera cultivation with the cover crops using.The greatest total CFU of bacteria occurred in the soil from the experimental combination where oat ploughed over in spring or autumn was the cover crops.The smallest total CFU of bacteria was obtained after
