The ethics of a Prophet of Islam (PBUH) in the Holy Qur’an and the Islamic era satirists
With the emergence of Islam faith throughout the Arabia Peninsula, the Arabian poetry entered a new era. The poets who eulogized Arab tribes’ ideals at the Pre-Islamic Ignorance Age, at the dawn of Islam changed their direction to spirituality or the adoration of God’s saints, especially the Prophet of Islam. The poets who exalted and revered the Prophet and his superior qualities in their poetry were generally devoted to the Islamic faith and exalted the Prophet genuinely and from the bottom of their heart. Some of these poets include HissanIbnThabit Ansari, AbdallhIbnRavaheh, KaebIbn Malik and KaebIbnZahir which their poetry has been recorded in the history. In their poetry on the Prophet, such poets defended the Prophet’s faith and supreme intentions and mostly eulogized His proper attributes such as generosity, affability, patience, forgiveness, honesty and sanctity, divine mission and prophecy, etc. and they utilized illuminating verses of the Holy Qur’an in their poetry and founded the basis of their artistic work on the commendation of the Prophet so as to achieve their own perfection.

Electrostatic properties and molecular orbital analysis of 1,2-di(cyclopenta-1,3-dienyl)ethyne molecular nanowire by computational study
The electrical characteristics and molecular orbital analysis of 1,2-di(cyclopenta-1,3-dienyl)ethyne molecule has been studied by using quantum chemical calculations coupled with density functional theory (DFT) using Gaussian09 program package. The molecule has been substituted with thiol, Au and Pt atoms at both ends of the molecule one by one and the corresponding variations in structural, electrostatic and transport properties have been analyzed. In this study, thiol atom acts as linker whereas Au and Pt atoms act as electrodes. Comparing with thiol substituted molecule the Au and Pt substituted molecules exhibit more variations in their structural properties. Atomic charges of the free molecule as well as all the substituted molecules have been compared with MPA and NPA charges. The HOMO-LUMO gap (HLG) of the molecule decreases gradually for S, Au and Pt substituted molecules respectively. The existence of small HLG of Au substituted molecule enhances the conductivity. Using Au as electrodes with thiol as linker, 1,2-di(cyclopenta-1,3-dienyl)ethyne can acts as an efficient molecular wire.

Effect of metal electrodes and transport properties of 2,5-divinylthiophene molecular nanowire under external electric field: A DFT study
The Au and thiol substituted 2,5-divinylthiophene molecule has been studied for the zero field and various levels of applied external electric fields (EFs) using quantum chemical calculations coupled with AIM theory. The variation in geometrical parameters due to the various external EFs and the corresponding transport properties of the molecule has been analyzed. The variation in MPA and NPA charges, the reduction of HOMO-LUMO gap (from 2.34 to 1.08 eV) and the increase of electric dipole moment (from 0.98 to 13.21 D) with the increase of external EFs (from zero to 0.26 VÅ-1) of the molecule reveals that using thiol as linker and Au as electrodes, 2,5-divinylthiophene molecule can be act as an efficient molecular nanowire.

Structural, Electrostatic and Transport properties of tetracene under applied electric field using quantum chemical calculations
To understand the structural and electrical characteristics of Au and thiol substituted tetracene, a quantum chemical calculation has been carried out with Density Functional Theory (DFT) coupled with the Bader’s AIM theory. The various levels of applied electric field (0 – 0.21 VÅ-1) altered the geometrical conformation as well as the electronic energy levels of the molecule. Variations in MPA and NPA atomic charges of the molecule for the applied fields have been compared. The field polarizes the molecule and hence the dipole moment of the molecule increases from 0.0002 to 14.65 D. For the zero bias, the HOMO–LUMO gap is1.752 eV, as the field increases this gap decreases to 1.03 eV, which reveals that it exhibits charge transfer ability for the applied field.

Tuning of a PDF controller used with a very slow second-order process
A second order process of 164.5 seconds settling time is controlled using a PDF controller (through simulation). The controller is tuned by minimizing the sum of square of error of the control system using MATLAB. Functional constraints are imposed on the maximum percentage overshoot, settling time and stability condition. The result was reforming the process slow response and producing a closed-loop control systems of a maximum percentage overshoot less than 2 % and a settling time less than 0.6. The performance of the tuned-PDF controlled process is compared with that tuned using the ITAE standard forms.

Revisiting Nationalism through Literary Mediations: A Reading of Sultan Tipu
Nationalism as a value is constantly rebuilt through legend making and selective arbitrary iconization / idealisation. Here, literature becomes an enabling medium to critically redefine these nationalist icons, liberating us from intimidating epic expectations by looking at the varied narratives. My paper aims to highlight such complexities underpinning the national identities of Indian past and also, as to how these personalities are re-figured in the post-nationalist discourse. I intend to foreground the rewriting of Tipu Sultan a historical figure, through a re-reading of H.S. Shiva Prakash’s play Tipu Sultan.

Variances in property values resulting from market evidence and non-standard anchoring and adjustments by valuers
The purpose of this paper is to determine the variances and significance of variances in capital values of properties in metropolitan Lagos of Nigeria resulting from anchoring and adjustment methods used by independent valuers in carrying out valuations within the scope of standard and non-standard anchoring paradigm. Valuation problems of ten properties were presented to 144 valuers in metropolitan Lagos to solve; but 104 (72.2%) participated in the experiment; and the One –sample t-test was used to test the variances. The significant P were all 0.00 for the ten properties; and this means that there are significant variances in estimates of property values determined by the valuers in the area of study. Crises in financial markets in Nigerian economy in the ending years of 2008 resulting from poor property valuation and unreliable values of collateral properties advised by independent valuers have heightened the need to find remedial measures to mitigate wide variances in the property values. Also, wide variances in capital values of real properties will result to clients losing confidence in values advised by valuation professionals.

Does employing reading activities significantly enhance Iranian EFL Learners’ Reading Proficiency?
Since in Iranian university context, reading comprehension is the most important skill to be acquired by the students, this study wanted to show whether implementing pre-, while-, and post-reading activities has a significant impact on Iranian EFL Learners’ reading proficiency or not. 28 sophomore students at Islamic Azad University in Lahijan (Iran) participated in this study and were divided into two groups: experimental and control group. The former received teaching reading activities such as deducting, inferring, note-taking, etc. as the treatment while the latter did not receive such a treatment. The treatment proved to be effective, that is, the experimental group surpassed the control group according to the post-test. Finally, it is hoped that material developers, teachers and testers will benefit from the findings of this study.

From monoclinic Mg2B2O5 nanowires to triclinic Mg2B2O5:Eu nanorods
In this paper we report on the synthesis of single-crystal Mg2B2O5 nanowires by heating the precursor powder made of disodium tetraborate decahydrate and magnesium chloride dihydrate at 8500C. The as-received nanowires possess smooth surface with diameters varying between 25 and 40 nm. Also Mg2B2O5 nanorods doped with Eu were synthesized by firing a mixture powder of the above obtained Mg2B2O5 nanowires and Eu2O3 in air atmosphere. The as synthesized Mg2B2O5:Eu nanorods have diameters varying between 110 and 130 nm. The structural and compositional characteristics of the as-synthesized products have been investigated by XRD, SEM, TEM, EDX, and SAED techniques. Photoluminescence investigations reveal that both Eu+3 and Eu+2 can coexist in Mg2B2O5 nanorods. Eu2 display a violet emission beak at 412 nm and Eu3+ display broad emissions centered at 538 and 615 nm.
