DISSOLUTION OF BENZENE IN THE SATURATED POROUS MEDIA
...Show More Authors

The aim of the present research is to study the dissolution and transport process of
benzene as a light nonaqueous phase liquid (LNAPL) in saturated porous media.
Unidirectional flow at water velocities ranged from 0.90 to 3.60 cm/hr was adopted to study
this process in a three dimensional saturated sand tank (100 cm×40 cm×35 cm). This tank
represents a laboratory-scale aquifer. The aquifer was constructed by packing homogeneous
sand in the rectangular tank. The experimental results were used to characterize the
dissolution behavior of an entrapped nonaqueous phase benzene source in a three dimensional
aquifer model. The time invariant average mass transfer coefficient was determined at each
interstitial velocity, the values of this coefficient were ranged from 0.016 to 0.061 cm/hr. It
was increased proportionally with velocity toward a limiting value. The results show that the
concentration of the LNAPL reduces as the distance increased in x and/or z direction from the
source of pollution. In most cases the benzene concentration declines with velocity more than
2.34 cm/hr at downstream of the LNAPL pool.

In Vitro the Effect of Canals Instrumented with Three Rotary Ni-Ti Systems on the Dislocation Resistanceo Guttafusion ® versus Single Cone Obturation Technique
...Show More Authors

Background: Complete seal of the root canal system following its chemo-mechanical debridement plays a pivotal role for achieving successful endodontic treatment. This can be established by reducing the gaps between the core filling material and root canal wall. Aim: To assess and compare the dislocation resistance of root canals obturated with GuttaFusion® and TotalFill BC sealer versus single cone obturation technique and TotalFill BC sealer after instrumentation of the canals with WaveOne, ProTaper Next and ProTaper Universal system. Material and Method: Sixty extracted human permanent mandibular premolars were conducted in the current study. The teeth were decorated and left the root with 15mm length; the roots were divided randomly i

FIRST RECORD OF THE LARGE-BILLED CROW CORVUS MACRORHYNCHOS WAGLER, 1827 PREDEATING ON THE VULNERABLE INDIAN ROOFED TURTLE PANGSHURA TECTA (GRAY, 1831) IN INDIA
...Show More Authors

The Vulnerable Indian Roofed Turtle Pangshura tecta (Gray, 1831) (Testudines: Geoemydidae) occurs in the Sub-Himalayan lowlands of India, Nepal, Bangladesh, and Pakistan. Little is known about its natural history, no studies have been conducted revealing its natural predators. In this study, a group of Large-billed Crow Corvus macrorhynchos Wagler, 1827 (Passeriformes: Corvidae) was observed hunting and predating on an Indian Roofed Turtle carcass in the bank of river Kuakhai, Bhubaneswar, India. The first record of this predation behaviour is reported and substantiated by photographic evidence.

The role of presupposition in the interpretation of the Qur'anic letters (Sharif Morteza, Mullah Sadra and Gonabadi): بررسی تأثیر پیش فهم‌ها بر فهم مفسران از حروف مقطعه در قرآن (شریف مرتضی، ملاصدرا و گنابادی)
...Show More Authors

The mysterious letters, the philosophy of existence and the meaning of these letters in the Qur'an is one of the mysterious issues that has always occupied the minds of Interpreters. Each Interpreter has tried to provide his own interpretation and understanding of these mysterious letters. Since these letters are part of the surah of the Qur'an and at the same time, the appearance of these letters, unlike other verses, does not indicate meaning, the commentators have approached these verses with their preconceptions. In this article, an attempt has been made to investigate the role of pre-interpreters of descriptors in a descriptive and analytical method in finding the meaning of syllables. However, each of them has tried to interpret th
