Abstract Background The studies of science, technology, engineering, and mathematics (STEM) career interests have progressed substantially over the recent years.However, the influence of career awareness on STEM career interests is an area that requires further discussion.Evidently, schulterblattanastomose Chinese adolescents have limited awareness
To study the mechanical effect of clay under acidic and basic conditions, typical clay minerals, montmorillonite and illite, were taken as the main research objects in this study.The variation law and mechanism of the cohesive force and internal friction angle were studied by immersing the remoulded soil in HNO3 solution with pH = 3 and NaOH (alkal
Abstract Background In the flowering plants, many polyploid species complexes display evolutionary radiation.This could be facilitated by gene flow between otherwise separate evolutionary lineages in contact zones.Achillea collina is a widespread tetraploid species within the Achillea millefolium polyploid complex (Asteraceae-Anthemideae).It is mor
Flash-X is a highly composable multiphysics software system that can be used to simulate physical phenomena baltimore a minuit in several scientific domains.It derives some of its solvers from FLASH, which was first released in 2000.Flash-X has a new framework that relies on abstractions and asynchronous communications for performance portability a
How to reduce the cogging torque of the integrated propeller motor is an important means to improve its noise performance because cogging torque is one of the key factors causing torque ripple.We proposed a method to reduce the cogging torque by optimizing the size of the Halbach array’s auxiliary pole.First, an analytical model for the airga
