In nitrogen poor soils legumes establish a symbiotic interaction with rhizobia that results in the formation of root nodules.These are unique plant organs where bacteria differentiate into bacteroids, which express the nitrogenase enzyme complex that reduces atmospheric N2 to ammonia.Nodule metabolism requires a tight control of the concentrations
Abstract Truck travel time prediction is the basis for real-time optimal scheduling decision of open-pit trucks.Most prediction models for open-pit truck travel time mainly rely on a single machine learning algorithm or model to optimize the hyperparameters, which is difficult to accurately capture the composite characteristics of truck travel time
IntroductionInjecting methamphetamine poses significant health risks, but little is known about how methamphetamine injectors filter their injection preparations and experience related health concerns.MethodsA chain-referral sample of Indigenous people who inject methamphetamine (n = 30) was recruited and semistructured interviews were conducted to
Coastal areas are dynamic areas with interactions between land and sea, which exposes complex challenges in integrated management.Law No.1 of 2014 on the management of coastal areas and small islands in Indonesia is a step to increase state authority in coastal waters management.However, environmental sustainability is often not a top priority in p
Wind turbines are known to cause bat fatalities worldwide.Ultrasonic acoustic deterrents are a potential solution to reduce impacts on bats, but few experimental field studies have been conducted at utility scale wind energy facilities.Our objective was to assess effectiveness of a recently developed deterrent for reducing bat fatalities at wind tu
