The economical design of plate loaded by pressure can be obtained by using stiffeners instead of increasing the thickness of plate. The main subject of this work is to obtain the effect of stiffener height on the maximum stress in the plate subjected to pressure load. Different plate-stiffener sets are selected to find the effects of stiffener thickness, plate dimensions and pressure, on the optimum stiffener height. The models under consideration are square plates clamped rigidly from four edges. Finite Element method is used to analyze 160 different models by using the Finite Element software package ANSYS version 11. Another analysis method based on maximum stress equation is used to analyze 30 models. The graphical comparison of results between two analytical methods is presented by a figure. It is found that the numerical results obtained by Finite Element Analysis converge to theoretical results. The optimum height of stiffener under above different effects is found. The critical pressure curves for square plate dimension sets are also presented.

Need and transgression in Surat (Abs) Semantic grammatical study: Need and transgression in Surat (Abs)
Praise be to God who blessed us with the grace of Islam
and set our tongues in the language of the Qur’an. The Arabic language is beautiful through its grammar and rules
and its meanings which are the spirit of grammar
and we allocate the element of Arabic speech
which is the verb and the phenomenon of necessity and transgression
one of the important phenomena in modern studies and received attention from ancient and modern scholars
and we called our research: (Obligatory and transgression in Surat Abbas
semantic grammatical study) . The research was divided into two sections: The first topic included: the necessary verbs in Surat (Abs) an applied study.
The research aims to highlight the significance and composition and the diversity of meanings and the Quranic context in the necessary and transgressive verbs in Surat (Abs).
This research consists of : a preamble , and two studies . The researcher addressed in the preliminary the importance of the phenomenon of necessity and infringement, the signs of the necessary action , the structure and controls of the act , the methods of infringement , its sections and signs.
As for the first topic : The researcher addressed the necessary verbs in Surat Abs , an applied study in terms of grammati
