Dual-wavelength mode-locked fiber lasers have attracted great attention due to their enormous potential in facilitating dual-comb spectroscopy.However, mechanism for dual-wavelength dissipative soliton mode-locking and the intracavity dynamics are still elusive.In this paper, we construct a simple and universal model to numerically investigate the
Broad Brush Surveys: a rapid qualitative assessment approach for water and sanitation infrastructure in urban sub-Saharan cities
IntroductionBroad Brush Surveys (BBS) are a rapid, qualitative assessment approach using four meta-indicators -physical features, social organization, social networks and community narratives - to gauge how local context interfaces with service/intervention options, implementation and uptake.MethodsIn 2021, responding to rapid urbanization and the
A Fast Metals Recovery Method for the Synthesis of Lithium Nickel Cobalt Aluminum Oxide Material from Cathode Waste
An approach for a fast recycling process for Lithium Nickel Cobalt Aluminum Oxide (NCA) cathode scrap material without bolia outlet gent the presence of a reducing agent was proposed.The combination of metal leaching using strong acids (HCl, H2SO4, HNO3) and mixed metal hydroxide co-precipitation followed by heat treatment was investigated to resyn
Transactional sex among Nigerian university students: The role of family structure and family support.
BackgroundThe reasons for the persistence of risky sexual behaviours among adolescents and young adults in sub-Saharan Africa despite the increasing knowledge about the associated risks continue to attract scholarly debates.Drawing from a cross-sectional study conducted among male and female Nigerian university students, we examined the relationshi
