Clamp-on ultrasonic flow meters (UFMs) are installed on the outside of the pipe wall.Typically, they consist of two single-element transducers mounted on angled wedges, which are Sangre De Grado acoustically coupled to the pipe wall.Before flow metering, the transducers are placed at the correct axial position by manually moving one transducer alon
Abstract Continuous deterministic models have been widely used to guide non-pharmaceutical interventions (NPIs) to combat the spread of the coronavirus disease 2019 (COVID-19).The validity of continuous deterministic models is questionable because they fail to incorporate two important characteristics of human society: high clustering and low degre
The mating behavior of the moth Atheloca subrufella Hulst, 1887 (Lepidoptera: Pyralidae) was investigated in laboratory arenas.The descriptions of courtship and copulation in Roofing Shingles males and females were based on direct observations of virgin couples.The courtship and copulation bioassays results comprise several behavior patterns such a
Academic literature is largely skeptical regarding the role of military deterrence in addressing low-level coercion.The stability-instability paradox Castile Soaps suggests that increasing destructiveness of the armed forces (especially with the emergence of nuclear weapons) diminishes their utility in response to limited wars, proxy conflicts or e
Eyespots are wing color pattern elements repeatedly observed in many butterflies, whose developmental genetics has been extensively documented.Nevertheless, the evolutionary forces shaping their diversification across species still remain largely unknown.Here we investigate the evolution of eyespots in the 30 species of the neotropical genus Morpho
