Abstract Transformation acoustics, as an unconventional theory, provides a powerful tool to design various kinds of acoustic devices with Over Ottoman Table excellent functionalities.However, the required ideal parameters, which are prescribed by the method, are both complex and hard to implement-even using acoustic metamaterials.Furthermore, simpl
Recycling is now, more than ever, an important part of any foundry process due to the high cost of energy.The basis of the work presented here is a study of the addition of foundry scrap returns to the melt in order to reduce material and energy costs.The most important issue in such a process is the quality of both the AEG HKB75NB540 75cm Five Bur
Thin films of nanocomposite of zinc oxide−reduced graphene oxide (ZnO-rGO) deposited on soda-lime glass substrates were prepared using ultrasonic spray pyrolysis (USP) at 460 °C.The preparation process does not use harsh acids and is environmentally friendly.The deposition period of 2, 3.5 and 5 min resulted in compact, uniform samples w
ABSTRACT Influenza A viruses cause an annual contagious respiratory disease in humans and are responsible for periodic high-mortality human pandemics.Pandemic influenza A viruses usually result from the reassortment of gene segments between human and avian influenza viruses.These avian influenza virus gene segments need to adapt to humans.Here we f
Non-orthogonal multiple access (NOMA) is envisioned as a promising technology that enhances the spectrum efficiency for future cellular networks.On the other hand, there is a growing interest in wireless powered sensor networks toward the sustainable realization of Internet of Things (IoT), as they may not require any battery replacement in princip
