In this paper, the vibration characteristics of multi-layer shell that internal and external surfaces with a layer of piezoelectric sensor and actuator is investigated. The backrest shell laminated with simple analytical method to evaluate and the results were compared with results obtained by other researchers. The numerical solution methods (GDQ) for shells with piezoelectric layers and plain...

Background: Empirical evidence regarding the connection between group development (maturity) and the success of software development teams is lacking. Since software development is primarily a product of team effort that involves human interaction, it is important to investigate the influence of group development on the performance of software development teams. Objective: The purpose of this r...

In this paper the nano conical shell model is developed based on modified strain gradient theory. The governing equations of the nano truncated conical shell are derived using the FSDT, and the size parameters through modified strain gradient theory have been taken into account. Hamilton’s principle is used to obtain the governing equations, and the shell’s equations of motion are derived with ...

Toll-like receptors (TLR) 7 and 9 transduce a cellular signal through the MyD88-dependent pathway and induce the production of inflammatory mediators against microbial nucleotide components. The repeated stimulation of TLR4 leads to endotoxin tolerance, but the molecular mechanisms of tolerance induced through the costimulation of individual TLR has not yet been established, although endosomal ...

Free vibration characteristics of continuous grading fiber orientation (CGFO) beams resting on variable Winkler and two-parameter elastic foundations have been studied. The beam is under different boundary conditions and assumed to have arbitrary variations of fiber orientation in the thickness direction. The governing differential equations for beam vibration are being solved using Generalized...

Despite its geographical and linguistic proximity to the Arabic language, Mahri (or Mehri) language (ISO 639-3: gdq) of Eastern Yemen Western Oman has remained a non-written into present era. While older generations speakers never considered prospect written idiom for their recent years have witnessed efforts compose circulate texts in language. These circumstances yielded poetic praxis that tr...
