In the present research, vibrational behavior of anisotropic protein microtubules (MTs) immersed in cytosol via Cooper–Naghdi shell model is investigated. MTs are hollow cylindrical structures in the eukaryotic cytoskeleton which surrounded by filament network. The temperature effect on vibration frequency is also taken into account by assuming temperature-dependent material properties for MTs....

The structure of the icy shells ocean worlds is important for understanding stability their underlying oceans as it controls rate at which heat can be transported outward and radiated to space. Future spacecraft exploration (e.g., by NASA's Europa Clipper mission) will allow higher-resolution measurements gravity shape than currently available. In this paper, we study sensitivity gravity-topogr...

  In the current work, the seismic analysis of bent region in buried pipes is performed, and effects of soil properties and modeling methods on pipe’s response are investigated. To do this task Beam, Beam-Shell Finite Element modeling and a Continuum shell FE models of a 90 degrees elbow are employed. In the Beam model, the pipe is simulated by beam elements while combined shell-beam elements a...

PdAu dendrimer-encapsulated nanoparticles (DENs) were prepared via sequential reduction of the component metals. When Au is reduced onto 55-atom, preformed Pd DEN cores, analysis by UV-vis spectroscopy, electron microscopy, and extended X-ray absorption fine structure (EXAFS) spectroscopy leads to a model consistent with inversion of the two metals. That is, Au migrates into the core and Pd res...

Mechanical soft reduction (MSR) is an effective method for elimination of the centerline segregation and porosity continuous casting steel slab, amount a key parameter that determines whether MSR could be applied successfully. In present work, 2D heat transfer model was developed predicting non-uniform solidification wide-thick slab. The measured shell thickness by nail shooting experiment slab...

in this study, an intelligent system for sorting closed shell and open shell pistachio nuts, was designed and developed based on combined acoustic and artificial neural network (ann) techniques. the system included a microphone, pc, material handling equipment and an air reject pneumatic mechanism. the microphone, placed under the steel plate, received sound signals generated by the pistachio n...

Botanical name of Cashew: Anacardium occidentale L CAS number: 8007-24-7 Area of growth of Cashew tree Coastal areas of Asia and Africa. Mozambique, India, Vietnam and Brazil Specification of Cashew nut shell The shell is about 0.3 ...

Uniform hollow spheres of Cu2O and CuS were successfully synthesized by chemical transformation of in situ formed sacrificial templates containing Cu(I) in aqueous solutions. The shell thickness of these hollow spheres can be adjusted through the choice of the bromide source used for the formation of intermediate templates. Specifically, thick-shell hollow spheres (about 130-180 nm in shell thi...
