Grotesque was introduced to European literature by the middle of sixteenth century, though previous definitions of this terminology were available before. Although this term was introduced to Aesthetics at the same time with its introduction to philosophy of arts, Kayser made it official and defined it as an expression of alienation and the chaotic world in the nineteenth century. Grotesque, as the definitions go, contains everything odd or strange. This oddity could be of humans, animals, spaces or amazing, strange or dispiteous situations. Generally, anything that contains these three characteristics while it is funny, is considered to be Grotesque. In this article, whit the library-documentary Method, alongside introducing definitions of this term, we reviewed Shirzad’s “Alexander the great”, the last part of the book “Eskandarnameh” regarding these elements. This stories presented, like all other stories of this book rich and special elements, it was divided into seven kinds of human, animal, grotesque atmosphere, language elements etc. This subject shows that vulgar stories also, like other stories can be the suitable background for this view.

This article presents analytical and empirical studies of a micro-electromechanical package. This micro-electro-mechanical (MEMS) pressure sensor package contains of a printed circuit board (PCB), the capacitance LCD. First of all, mathematical modeling and computer simulation using software COMSOL software which is based on finite element method are presented to compute the sensitivity of the MEMS pressure sensor and output voltage output. It is worth noting that an Xducer resistor type is adopted to measure the diaphragm deflection. In addition to static and modal analyses of the sensor, the effects of geometric parameters on the voltage has also been studied. Simulation results show that by changing the size and position of the resistor and also the size and thickness of the diaphragm, sensor sensitivity can be changed. Then, with the construction and placement of components on printed circuit boards, the package has been prepared and tested in a laboratory. The experimental results of the package show that the error of the devised system in measuring the pressure is less than 0.5 percent. This pressure sensor package is capable of accurately measuring the pressure up to 6 bar in which all the empirical results are presented at the end of the study. The package can be designed according to the requirements of the petrochemical industry in measuring gas pressure of storage tanks and drums in FANAVARN petrochemical company.
