A theoretical and protection study was conducted of the corrosion behavior of carbon steel surface with different concentrations of the derivative (Quinolin-2-one), namly (1-Amino-4,7-dimethyl-6-nitro-1H-quinolin-2-one (ADNQ2O)). Theoretically, Density Functional Theory (DFT) of B3LYP/ 6-311++G (2d, 2p) level was used to calculate the optimized geometry, physical properties and chemical inhibition parameters, with the local reactivity to predict both the reactive centers and to locate the possible sites of nucleophilic and electrophilic attacks, in vacuum, and in two solvents (DMSO and H2O), all at the equilibrium geometry. Experimentally, the inhibition efficiencies (%IE) in the saline solution (of 3.5%) NaCl were studied using potentiometric polarization measurements. The results revealed that the (%IE) for carbon steel corrosion by ADNQ2O is (89.88%). The obtained thermodynamic parameters support the physical adsorption mechanism. The adsorption followed the Langmuir isotherm. The surface change on carbon steel was studied using SEM (Scanning Electron Microscopy).
كشفت دراسات ما بعد البنيوية والتطور الحاصل في الدراسات النقدية عن مقدار التداخل بين النصوص في انتاج الظواهر الادبية ، وخير ما يكشف هذا التداخل هو المنهج الذي يركز على دراسة التناص ولاسيما في النصوص التي تتشكل على وفق التناص الواعي الذي الذي يتألف من مجموعة نصوص ادبية يتفاعل فيها نص الكاتب مع نصوص اخرى.
This research deals with the idea of how the poetic reading can be a
rich field for producing the potential meanings in each text, through observing
the connection of the words and their link with other, thus composes, from the
collection of these interlaced meanings, what is called the poetic significant
(Symbolic) elaboration which deals with the reader of the text by regarding
him as a producer not as a consumer who can read a conscious reading, and
be diligent to solve the problem of the links of the relations among the
inspiring words because the language of poetry is an inspired language which
is capable of diversity and multiplicity of readings which is called the Symbolic
elaboration.
The Andoluosian literatures has been captured my mind, and had a very
pure and great place in my spirit, which is remembering me the roots of
genuine Arabic civilization spread during eight century in endoluos region.
also the Arabic creation which is moved from east to far way land in that
ages. And very clearly appearance tremendous men interested in science and
all kind of literature and arts especially in poetry, no one who has taste and
minimum knowledge can denied the effect of indoluosan prosperity among
readers. So for that reason I work very hard to choose a very famous poet his
nick name (Al-Ramadee) he is Youseif Bin Haroon born in the first decade
of the 4TH hijri (Islamic Calendar), died in (403H).
ارتبط الانسان بالطبيعة بأشكالها المختلفة ارتباطا وثيقا ، فهي تمثل الحاضنة له بمجالات حياته كلها، فما كان من الأدباء الا أن يجعلوها في كثير من الأحيان مادة لأدبهم وأرضية خصبة لنتاجهم، فتمظهرت بصورها المختلفة وحاجة الانسان لها وخيرها وشرها في الأدب على مدى التاريخ، والعرب شأنهم شأن غيرهم من الأمم فمنذ عصر ما قبل الاسلام كانت الطبيعة منفذا مهما وملجأ للشعراء في انتاج الأدب وابداعه وإلى يومنا هذا، ونحن إذ نتحد

« This paper presents the indicators of the development of excellent public relations in the institutions of higher education that are possible for three contextual variables: institutional, professional, professional, and effective communication. Therefore, the study used six indicators to measure the excellent public relations in institutions of higher education and scientific research. These indicators are based on the theory of excellence in public relations . Research Objectives: The aim of the research paper is to uncover the institutional, professional, and professional indicators of effective communication of excellent public relations in higher education institutions.
