A novel wideband multiplexer is introduced as a communications equipment solution in order to provide simultaneous operation of satellite and terrestrial services 9x11 pergola in the dedicated $K$/$Ka$ frequency bands (passbands ranging from 19.5 GHz to 30.5 GHz).Advanced RF filtering techniques are applied in order to accommodate a compact multipl
The growing requirement imposed by dam safety regulations and guidelines necessitates the improvement and rehabilitation of rockfill embankment dams.These hydraulic structures are of great importance, and they can be subjected to overtopping flows which can significantly compromise the structural integrity.One of the defense mechanisms utilized is
Spatial cognition in vertebrates is adversely affected by a lack of environmental complexity during early life.However, to our knowledge no previous studies have tested the effect of early exposure to varying degrees of environmental complexity on specific components of spatial cognition in chickens.There are two main rearing systems for laying hen
Machines and equipment for asphalt pavement milling are widely used throughout the world.With the growth of road construction, the demand for this class of machinery also rises.At the same time, the optimization of design and technological parameters of the milling machines is impossible without a comprehensive study of processes of milling asphalt
