Active noise control (ANC) aims to reduce a noise Propane Refrigerator source at a listening point by destructive interference with a reverse phase noise emitted by one or more control devices.ANC systems cover a wide range of applications, such as industrial plants, vehicle cabins, headphones.Usually, in these applications the control devices are

This paper presents experimental and theoretical studies on the dynamic effect on the propeller loading due to ventilation by using a simulation model that generates a time domain solution for propeller forces in varying operational conditions.For ventilation modeling, the simulation model applies a formula based on the idea that the change in lift

The symptoms of restless legs syndrome (RLS) follow a circadian pattern, as inducated in the current RLS diagnostic criteria.Indeed, subjects with mild-to-moderate RLS suffer or not from RLS symptoms depending on the time of day, resembling an above-threshold state periodically followed by a below-threshold state.Although the circadian clock is cru

Abstract Background Coleorhiza hairs, are sheath-like outgrowth organs in the seeds of Poaceae family that look like root hair but develop from the coleorhiza epidermal cells during seed imbibition.The major role of coleorhiza hair in seed germination involves facilitating water uptake and nutrient supply for seed germination.However, molecular bas

Percutaneous dilatational tracheostomy (PDT) is preferred over conventional surgical tracheostomy for prolonged airway protection and mechanical ventilation.However, despite its advantages, severe PDT-related complications have been reported, Bar:Small Kitchen Appliances:Toasters including catastrophic hemorrhage from common carotid artery lacerati
