Heavy metal pollution in soil is becoming more and more serious.LIBS is one of the most promising technologies for rapid detection of heavy metal contamination in soil.However, due to the wide variety of soils and complex matrices, accurate quantification remains a challenge.In total, 451 soil samples were prepared and detected by the portable dete
This article looks at public anti-restriction protests by framing public space as a vital component of urban life.It argues that the body is rarely introduced as a scale of spatial analysis and usually plays a more prominent role in the subfields of social movement or public space studies, which often tend to focus on the transformative and emancip
Instrument current transformers (CTs) measure AC currents.The DC component in the measured current can saturate the transformer and cause gross Headphones error.We use fluxgate detection and digital feedback compensation of the DC flux to suppress the overall error to 0.15%.This concept can be used not only for high-end CTs with a nanocrystalline c
The Dandelion antimicrobial nature of honey and its related apiological origins typically focus on basic chemical analysis without attempting to understand the diversity of the microbial component.The antibacterial activity, chemical characterization, and diversity of bacteria isolated from Apis mellifera honey stomachs and hive honey collected thr
The ability to acquire chemical defenses through the diet has evolved across several major taxa.Chemically defended organisms may need to balance chemical defense acquisition and nutritional quality of prey items.However, these dietary preferences and potential trade-offs are rarely considered in the framework of diet-derived defenses.Poison frogs
