Through energy conservation and transformation perspectives, we numerically investigated the physical mechanism of cavitation generation surrounding the two-dimensional NACA 0015 hydrofoil using here the mass-transfer cavitation model and modified-RNG k-epsilon model.Cavitation generation is triggered by strong turbulent kinetic energy (TKE) with p
The proximate causes of sexual size dimorphism in Phrynocephalus przewalskii.
Sexual size dimorphism (SSD) is a common phenomenon and is a central topic in evolutionary biology.Recently, the importance of pursuing an ontogenetic perspective of SSD has been emphasized, to elucidate the proximate physiological mechanisms leading to its evolution.However, such research has seldom focused on the critical periods when males and f
Case report: Parasitism of Ornithonyssus bursa (Macronyssidae) in humans in the Taquari River Valley region, southern Brazil
Ornithonyssus bursa hematophagous mite whose main host is wild and domestic birds, which can temporarily parasitize humans in the absence of the main bostik roll-cote host.Infestations occur when birds abandon nests or direct contact with infected birds.The specimens were collected in a house in the urban area, with the help of a paper towel and ke
