Parrots and songbirds learn their vocalizations from a Cropped Oversized Button Up conspecific tutor, much like human infants acquire spoken language.Parrots can learn human words and it has been suggested that they can use them to communicate with humans.The caudomedial pallium in the parrot brain is homologous with that of songbirds, and analogou
Abstract An advanced organic photodetector (OPD) with a butter layer of Si-rich silicon oxynitride (SiOxNy) was fabricated.The detector structure ZINC CITRATE is as follows: Indium tin oxide (ITO) coated glass substrate/SiOxNy(10 nm)/naphthalene-based donor:C60(1:1)/ITO.Values of x and y in SiOxNy were carefully controlled and the detector performa
Thermal-induced spalling is a typical failure behavior of concrete materials exposed to high temperatures.This study uses Abaqus to establish a numerical model of concrete material comprising aggregates and mortar matrix.Cohesive elements considering heat conduction are embedded into this numerical model to simulate the thermal-induced explosive sp
Abstract Background Anopheles gambiae sensu stricto is considered to be highly anthropophilic and volatiles of human origin provide essential cues during its host-seeking behaviour.A synthetic blend of three human-derived volatiles, ammonia, lactic acid and tetradecanoic acid, attracts A.gambiae.In addition, volatiles produced by human skin bacteri
Objective: to study the current state of the legislative regulation of nicotine-containing products turnover and consumption; to identify the main problems in this area and to suggest possible ways to solve them.Methods: the methodological basis of the work is interdisciplinary, systematic and comparative approaches, as well as general scientific m
