Deducing the stage-discharge relationship for contracted weirs by the outflow theory of Malcherek
2019
The aim of this paper was the deduction of a new stage-discharge relationship for a contracted weir, having a crest length less than the channel width, by using the Malcherek’s outflow theory. The average outflow velocity over the rectangular contracted weir was expressed in terms of the head over weir, the momentum correction coefficient and the ratio between the crest length and the channel width. This theoretically deduced stage-discharge formula was calibrated by measurements carried out for values of the ratio between the crest length and the channel width ranging from 0.3125 to 0.9375. In particular, a relationship to estimate the momentum correction coefficient for contracted weirs w…
Human olfactory communication: current challenges and future prospects
2020
Although anthropologists frequently report the centrality of odours in the daily lives and cultural beliefs of many small-scale communities, Western scholars have historically considered the sense of smell as minimally involved in human communication. Here, we suggest that the origin and persistence of this latter view might be a consequence of the fact that most research is conducted on participants from Western societies who, collectively, were ratherold(adults),deodorizedanddesensitized(ODD) to various aspects of olfactory perception. The view is rapidly changing, however, and this themed issue provides a timely overview of the current state-of-the-art on human chemocommunication. Based …
"Mroczna otchłań". Archetypowa interpretacja opowiadania "Przemiana Juana Romero" Howarda P. Lovecrafta
2020
The setting of “The Transition of Juan Romero” – the short story by Howard Phillips Lovecraft, who was the originator of modern American horror fiction – is “the gold mine in the Cactus Range”. Drawing on the theories of Carl Gustav Jung, the author of the present interpretation amplifies the cultural dimensions of Lovecraft’s text, giving prominence to its origin from the ancient myths of the Aztecs, and using the so-called psychological alchemy to show the archetypal symbolism and structure of the story. Such a critical perspective, which takes into account different layers of the authorial intentionality and the reader’s response, reveals the complexity of the characters and situations, …

New Stage–Discharge Relationship for Triangular Broad-Crested Weirs
2022
Simple hydraulic structures, such as weirs, allow measuring flow discharge by using the upstream flow depth and a stage–discharge relationship. In this relationship, a discharge coefficient is introduced to correct all the effects neglected in the derivation (viscosity, surface tension, velocity head in the approach channel, flow turbulence, non-uniform velocity profile, and streamline curvature due to weir contraction). In this paper, the dimensional analysis and the incomplete self-similarity theory are used to investigate the outflow process of triangular broad-crested weirs, characterized by different values of the ratio between crest height p and channel width B, and to theoretic…
