Abstract Low atmospheric oxygen levels during the mid-Proterozoic were occasionally interrupted by transient high oxygen levels.The cause of mid-Proterozoic ocean redox variability remains unclear.Here we investigate mercury chemostratigraphy across the Jixian section of North China Craton through two oxygenation intervals.Abnormal Fan Shop - Other
ABSTRACT The objective with this study was to calculate the total cost of maize production and beef cattle Rear Console Cover in permanent pasture activities in separate production systems (conventional) and integrated systems (maize production plus beef cattle), as well as to verify economic gains explained by the economy of scope.The first step f
The Florida harvester ant (Pogonomyrmex badius) excavates deep nests in the sandy soils of the Gulf and Atlantic coastal plains.Nest relocations of over 400 colonies in a north Florida coastal plains pine forest were tracked and mapped from 2010 to 2013.Individual colonies varied from one Fan Shop - Other - Miscellaneous move in two years to four t
Traffic sensors play a pivotal role in monitoring and assessing network-wide traffic conditions.However, the substantial costs associated with deploying an extensive sensor network across real-world highway systems can often prove prohibitive.Thus, the strategic selection of optimal sensor locations within budget and resource constraints becomes im
In several industrial applications, plastic, composites and ceramics replace a number of metallic structures such as copper, aluminum and steel.Most recently installed piping water and gas systems in the world are made of thermoplastic due to its advantages, for example, low cost, ease of fabrication and corrosion resistance.In this work, the chose
