Background and Aim: Mucoepidermoid carcinoma (MEC) is the most common malignant neoplasm of the salivary glands with complex histopathologic features and clinical behavior. The aim of this study was to evaluate the clinicopathologic significance of p63, Maspin and matrix metalloproteinase (MMP)-2 expression in MEC. Materials and Methods: In this retrospective study, immunohistochemical stain...

While the existing thermomechanical constitutive models can predict the behavior of SMAactuated systems in most cases, in this study, we have shown that there are certain situations in which these models are not able to predict the behavior of SMAs. To this end, a rotary SMA-actuated robotic arm is modeled using the existing constitutive models. The model is verified against the experimental re...

according to the importance of careful review of crude oil market fluctuations on the iranian economy, in this paper a multivariate model of markov switching vector error correction model (have been used). variables such as real gross domestic product in industrial sector, real effective exchange rate, real governmental expenditure, real import, inflation rate and real crude oil price is used t...

Despite the potential of these alloys and the amount of patents, successful industrial and commercial applications of Shape Memory Alloys (SMA) remain exceptions. This can be explained by the lack of design tools able to dimension correctly SMA elements because the non elastic behavior of SMA lead the classical method of design to be inefficient. Furthermore, this behavior is strongly dependent...

In this paper, seismic behavior of the existing buildings equipped by friction dampers is studied. Seismic performance of6-story, 9-story and 12-story steel buildings with damper and without damper were studied. The finite element modeling technique (SAP2000 Software) is used for analysis. Time History analyzing was done to achieve this purpose. For nonlinear dynamic analysis, the responses of ...

the iranian poultry sector has experienced many significant structural changes in recent years. such changes may have influenced price dynamics and transmission of shocks through marketing channels especially on retail markets. this paper investigate price transmission, threshold behavior and asymmetric adjustment in poultry sector of ardebil (ar), east azerbaijan (ea) and west azerbaijan (wa) ...

Shape Memory Alloys (SMA) have the unique capability to recover the original shape, once mechanically deformed, through mechanical unloading, Superelastic Effect (SE), or through thermal loading, Shape Memory Effect (SME). These peculiar behaviors, coupled with a good material biocompatibility, have stimulated a wide diffusion of SMA in the area of biomedical devices. In this work we numericall...
