BACKGROUND:The risks of HIV transmission associated with the opioid epidemic make cost-effective programs for people who inject drugs (PWID) a public health priority.Some of these programs have benefits beyond prevention of HIV-a critical consideration given that injection drug use is increasing across most United States demographic groups.To ident
In current-generation designs of total primary hip joint replacement, the prostheses are fabricated from alloys.The modulus of elasticity of the alloy is substantially higher than that of the surrounding bone.This discrepancy plays a role in a phenomenon known as stress shielding, in which the bone bears a reduced proportion of the applied load.Str
Abstract Background Fungi are an attractive source of nutrients for predators.As part of their defense, some fungi are able to induce the production of anti-predator protein toxins in response to predation.A previous study on the interaction of the model mushroom Coprinopsis cinerea by the fungivorous Ladies hat nematode Aphelenchus avenae on agar
Electrical monitoring technology is widely applied in mines with high risk of water inrush because of its high sensitivity to the change of coal resistivity.However, due to the complex working environment of the two lanes of the underground working face, the ground conditions between the different field source emission monitoring electrodes are qui
Power system inertia is an essential part of grid frequency control.The number of synchronously connected machines, which inherently provide inertia, is decreasing due to the transition to renewable energies.Conventional generation units are being replaced by renewable generation units which are connected to the grid via frequency converters.Some p
