To alleviate girls sweatpants the problem of unsatisfactory target strength and scattering stability of an underwater corner reflector, a method to enhance the acoustic scattering characteristics using a vacuum cavity as an acoustic reflecting layer is proposed.According to the principle of acoustic impedance mismatch of a water-reflecting layer, a
Abstract Background Bast fibres are characterized by very thick secondary cell walls containing high amounts of cellulose and low lignin contents in contrast to the heavily lignified cell walls typically found in the xylem tissues.To improve the quality of the fiber-based 3 Seater Sofa products in the future, a thorough understanding of the main ce
Barley (Hordeul vulgare L.) is the fourth most important cereal crop based on production and cultivated area.Biotic stresses, especially fungal diseases in barley, are devastating, incurring high possibilities of absolute yield loss.Identifying superior #syd-hill-oilskin-coat-childs and stable yielding genotypes is crucial for accompanying the incr
Background.Despite a significant number of theoretical and experimental studies, the issue of determining the threshold levels of pulsed acoustic exposure, when exceeded, 3 Seater Sofa their negative effect on the morphofunctional state of a biological object begins to appear.Traditionally, in laboratory conditions, such estimates are obtained in e
