Abstract We show how knowledge of the cold dark matter (CDM) density can be used, in conjunction with measurements of the parameters of a scenario for beyond the Standard Model (BSM) physics, to 3701129802670 provide information about the evolution of the Universe before Big Bang Nucleosynthesis (BBN).As examples of non-standard evolution, we consi
In this blueberry flash drive paper, a co-axial dual-mechanical ports flux-switching permanent magnet (CADMP-FSPM) machine for hybrid electric vehicles (HEVs) is proposed and investigated, which is comprised of two conventional co-axial FSPM machines, namely one high-speed inner rotor machine and one low-speed outer rotor machine and a non-magnetic
Background Measures of whole-body angular momentum in the sagittal plane are commonly used to characterize dynamic balance during human walking.To compute angular momentum, one must specify a reference point about which momentum is calculated.Although biomechanists primarily compute angular momentum about the center of mass (CoM), momentum-based co
Background: This study explored the association between sexual health literacy (SHL) and preventive nucleus ball toy behaviors of pregnancies and sexually transmitted diseases (STDs) among middle-school students during the COVID-19 outbreak to aid in the development of an informative program.Methods: Mixed-method study with stratified two-stage clu
Anionic surfactants (AS) are detrimental aquatic pollutants due to their well-characterized toxicity to aquatic organisms.The concentration of AS in aquatic environments is increasing because of their extensive use in many industries and households.The standard reference method for AS analysis is to determine a methylene blue active substance (MBAS
