This article deals with the thermal vibration analysis of graphene-oxide powder-reinforced (GOPR) nanocomposite plates, once plate is embedded on viscoelastic substrate. The structure subjected to loadings various temperature rises such as sinusoidal rise (STR), linear (LTR), and uniform (UTR). Damping behavior GOPR plates investigated based variations natural frequencies. Four functionally graded (FG) patterns GOPs' distribution are taken into account comparatively in order find out best...
Magnetorheological elastomers (MREs) are polymers reinforced by ferromagnetic particles that show magnetic dependent behavior. Mixing MREs with reinforcing fibers can create a new class of material so-called “MRE composites, MRECs” additional functionalities and properties. Here, using Generalized Maxwell model, we proposed magnetic-dependent rheological model considering the hysteresis phenomenon for to predict dynamic damping responses MREC plates in frequency domain. We also investigated...

Background and aims Peripheral nerve block (PNB) is commonly used, but there a lack of data on its effectiveness safety in the clinic. Therefore, anesthesiologists have limited insight into how they are faring terms both efficacy. Additionally, No PNB registry recorded IRAN. Herein, we reveal hospital might use information gathered outcomes to guide future quality enhancement efforts. Method This was an observational, prospective, unicenter study all peripheral blocks done operating room...
