INTERFACIAL BONDING MECHANISM AND LENGTH EVALUATION METHOD OF THE LONGITUDINAL WELDS IN THE UNSTEADY DEFORMATION PROCESS OF PORTHOLE DIE EXTRUSION OF ALUMINUM ALLOY PROFILES

In this work, a porthole die extrusion experiment was carried out on an aluminum alloy profile used for air-conditioning refrigerator ice box.Microstructural characterization and mechanical property tests were performed at different positions of a longitudinal weld in the profile head.The results indicated that, from the unsteady to steady extrusio

Background.Atlantic horse mackerel, Trachurus trachurus (Linnaeus, 1758), is among bento-pelagic species subject to discard within deep-water rose shrimp fisheries, and how such species would react to light wavelength is therefore important, to be consistent with the Common Fishery Policy (CFP).Despite the existing literature currently available, t

Introduction.To solve the problem of accelerating the construction of roads, improving their quality, it is advisable to use a continuous action unit to form a underlying layer.The main working bodies of this unit are buckets, which cut off the soil layer from below and on the side.At the same time, the bottom knife cuts off the ground layer from b

BackgroundThe effects of military environmental exposures (MEE) such as volatile organic compounds (VOCs), endocrine-disrupting chemicals (EDCs), tactile herbicides, airborne hazards and open burn pits (AHOBP), and depleted uranium on health are salient concerns for service members and Veterans.However, little work has been done to investigate the

The American television show Rick and Morty, an animated science fiction sitcom, FACIAL SCRUB critiques speciesism in the context of bleak existentialist philosophy.Though the show focuses primarily on human characters, it also depicts various forms of artificial sentience, such as robots or clones, undergoing existential crises.It explicitly effac
