One hundred items of 60 talcum powders and 40 body lotions were examined for their total aerobic bacterial, coliform and fungal counts.We also carried out anaerobic bacterial counts for talcum powder as well as tests to detect some potentially hazardous bacteria in all tested samples.Talcum powders were more heavily contaminated with bacteria than
To clarify the effect of Hindered amine light stabilizer (HALS) on ultraviolet (UV) aging behavior of asphalt binder, the evolution history and characteristics of the UV induced micro-structure of modified asphalt were characterized.Scanning Electron Microscope (SEM) and Atomic Force Microscope (AFM) were used to analyze the microscopic morphology
Tiller number serves as a crucial indicator of total yield in agriculture.Accurately monitoring tiller numbers is essential for guiding variable fertilization to optimize inputs and enhance final yields.Currently, most of the existing winter wheat tillering sensing monitoring methods cannot meet the three requirements of fast, accurate and efficien
Local governments in Sub-Saharan Africa face the daunting task of high urban growth and potentially devastating impacts of climate change across local communities and the economy.Urban and peri-urban food production can be among nature-based strategies planned for improving urban food security, reducing emissions, and climate adaptation.Co-operativ
