In this paper, a mathematical strip-saturation model is proposed for a poled transversely isotropic piezoelectric plate weakened by two impermeable unequal-collinear hairline straight cracks. remotely applied in-plane unidirectional electromechanical loads open the cracks in mode-I such that the saturation zone developed at the interior tips of cracks gets coalesced. The developed saturation zones are arrested by distributing over their rims in-plane normal cohesive electrical displacement. The problem is solved using the Stroh formalism and the complex variable technique. The expressions are derived for the stress intensity factors （SIFs）, the lengths of the saturation zones developed, the crack opening displacement （COD）, and the energy release rate. An illustrative numerical case study is presented for the poled PZT-5H ceramic to investigate the effect of prescribed electromechanical loads on parameters affecting crack arrest. Also, the effect of different lengths of cracks on the SIFs and the local energy release rate （LErr） has been studied. The results obtained are graphically presented and analyzed.

This paper describes the design and construction of the Taban tokamak, which is located in Amirkabir University of Technology, Tehran, Iran. The Taban tokamak was designed for plasma investigation. The design, simulation and construction of essential parts of the Taban tokamak such as the toroidal field(TF) system, ohmic heating(OH) system and equilibrium field system and their power supplies are presented. For the Taban tokamak, the toroidal magnetic coil was designed to produce a maximum field of 0.7 T at r?=?0.45 m. The power supply of the TF was a130 kJ, 0–10 kV capacitor bank. ripples of toroidal magnetic field at the plasma edge and plasma center are 0.2% and 0.014%, respectively. For the OH system with 3 kA current, the stray field in the plasma region is less than 40 G over 80% of the plasma volume. The power supply of the OH system consists of two stages, as follows. The fast bank stage is a 120 μF, 0–5 k V capacitor that produces 2.5 kA in 400 μs and the slow bank stage is 93 mF, 600 V that can produce a maximum of 3 kA. The equilibrium system can produce uniform magnetic field at plasma volume. This system’s power supply, like the OH system, consists of two stages, so that the fast bank stage is 500 μF, 800 V and the slow bank stage is 110 mF, 200 V.

The purpose of the present study is to examine the impact of initial geometric imperfection on the nonlinear dynamical characteristics of functionally graded carbon nanotube-reinforced composite(FG-CNTrC) rectangular plates under a harmonic excitation transverse load. The considered plate is assumed to be made of matrix and single-walled carbon nanotubes(SWCNTs). The rule of mixture is employed to calculate the effective material properties of the plate. Within the framework of the parabolic shear deformation plate theory with taking the influence of transverse shear deformation and rotary inertia into account, Hamilton’s principle is utilized to derive the geometrically nonlinear mathematical formulation including the governing equations and corresponding boundary conditions of initially imperfect FG-CNTrC plates. Afterwards, with the aid of an efficient multistep numerical solution methodology, the frequency-amplitude and forcing-amplitude curves of initially imperfect FG-CNTrC rectangular plates with various edge conditions are provided, demonstrating the influence of initial imperfection,geometrical parameters, and edge conditions. It is displayed that an increase in the initial geometric imperfection intensifies the softening-type behavior of system, while no softening behavior can be found in the frequency-amplitude curve of a perfect plate.

The continuous awareness campaigns about Colorectal Cancer (CrC) directed towards the Lebanese population in order to foster preventive medicine are on the rise. The impact has been positive and reported in previous research, although the number of victims is still high. This paper aims to perform a recent cross-sectional study of Lebanese residents’ CrC awareness by comparing the findings of two studies carried out in the years 2016 and 2018. The samples of the current study include 1140 (2016) and 993 (2018) participants who completed a simple structured questionnaire directed to assess their knowledge of colon cancer and the behavioral intentions of obtaining CrC screening. Upon comparing results, the percentage of those who know about CrC has increased significantly from 40.4% in 2016 to 78.7% in 2018, the proportion of respondents who believed that family history is the major risk factor for CrC did increase significantly from 47.7% in 2016 to 90.8% in 2018. Likewise, the proportions of respondents who believed that overweight, age, and stress are among the major risk factors for CrC increased from 26.9%, 26.7% and 11.3% in 2016 to 86.2%, 52.1% and 21.51% in 2018, respectively. On the other hand, the proportions for the risk factors related to alcohol and smoking have dropped from 37.7% and 37.3% to 27.4% and 24.2%, respectively. Moreover, the most important source of information for CrC was friends (18.4% in 2016 versus 73.8% in 2018), followed by family (18.7% in 2016 versus 56.7% in 2018), and then physicians (18.9% in 2016 and 40.2% in 2018). In fact, the efforts of the non-governmental organization (NGO) SAID (118 different major activities in the span of 3 years) did make a significant difference in what relates to CrC awareness among the Lebanese population. These findings are used to encourage and support other NGOs to adopt targeted new awareness campaigns which have proven successful, and to present evidence based on facts to government officials in t

In the Bayesian mixture modeling framework it is possible to infer the necessary number of components to model the data and therefore it is unnecessary to explicitly restrict the number of components. Nonparametric mixture models sidestep the problem of finding the ＂correct＂ number of mixture components by assuming infinitely many components. In this paper Dirichlet process mixture （DPM） models are cast as infinite mixture models and inference using Markov chain Monte Carlo is described. The specification of the priors on the model parameters is often guided by mathematical and practical convenience. The primary goal of this paper is to compare the choice of conjugate and non-conjugate base distributions on a particular class of DPM models which is widely used in applications, the Dirichlet process Gaussian mixture model （DPGMM）. We compare computational efficiency and modeling performance of DPGMM defined using a conjugate and a conditionally conjugate base distribution. We show that better density models can result from using a wider class of priors with no or only a modest increase in computational effort.
