In this research, a 1064 nm single-longitudinal-mode (SLM) vortex beam was generated from an annular-pumped Nd:YVO _4 microchip laser, in which a circular Dammann grating was Pheasant Oak Serving Board used to reshape the 808 nm pump light into an annular intensity profile.As a result, the laser emitted a SLM LG _01 beam with a maximum output power
In order to investigate the impact of marine propeller wake fields on sediment siltation in shallow water channels, this study employs the unsteady RANS approach and the Volume of Fluid model.A full-scale numerical self-propulsion test was conducted on a 50,000 DWT oil tanker under the influence of a free surface.The research includes forecasting t
Erb-b2 receptor tyrosine kinase 2 Exfoliants (ErbB2) is an oncogene that frequently overexpressed in a subset of cancers.Anti-ErbB2 therapies have been developed to treat these types of cancers.However, less is known about how anti-ErbB2 drugs affect the trafficking and degradation of ErbB2.We demonstrate that the reversible and irreversible tyrosi
Taking a new type of prefabricated building wall Black Tea panel installation machine as the research object, the mechanism configuration and specific implementation are analyzed, the kinematic and dynamic mathematical models of the boom landing mechanism are established, and the functional relationship between the maximum load of the cylinder and
Nest site has influence on incubation duration and hatching success of two Neotropical turtles, the Giant Amazon River Turtle (Podocnemis expansa) and Yellow-Spotted Side-Neck Turtle (Podocnemis unifilis - "Tracajá").The 2000 and 2001 nesting seasons have been monitored at the Javaés River in Bananal Island, Brazil.Although they nest on the same
