Volume 3, Issue 1 , March 2013, Pages 13-16

  Heavy metals are highly poisonous in the environment, even in small quantities, and endanger certain species and all live beings. Current methods of removing heavy metals from aqueous media include chemical sequestration, ion exchange, surface absorption, membrane processes, oxidation and revival procedures ...  Read More

Study of the rate of organic oil pollutants (PAHS) and heavy metals (V, Ni, Hg) in the four regions, Siri, Lavan, Khark and Bahregan in the Persian Gulf

M. Kashefiolasl; H. Zargarlelahi

Volume 3, Issue 1 , March 2013, Pages 25-32

  Pollution of marine waters is one of the important issues that has a irreparable effects. Also, in the organic oil pollutants, due to inappropriate effects on the environment and humans health and ability to create cancer, hydro carbons of polycyclic (PAHS) and heavy metals (Ni,Hg,V) have a particular ...  Read More

Nonlinear statics analysis of on offshore jaket platform in the case of explosion

M. Tajari; F. Azarsina; N. Ashrafi Khorasani

Volume 3, Issue 1 , March 2013, Pages 33-42

  Explosion and fire on an offshore rig can lead to its minor or complete damage and sinking which means the loss of life or environmental pollution. Hence the use of techniques such as blast wall is crucial to reduce the detrimental effects. These blast walls are designed for explosion wave of length ...  Read More

Simulation and optimization of live fish locomotion in a biomimetic robot fish
Volume 3, Issue 1 , March 2013, Pages 17-24

  This paper presents simplified hydrodynamics model for a biomimetic robot fish based on quantitative morphological and kinematic parameters of crangiform fish. The motion of four Pangasius sanitwongsei with different length and swimming speed were recorded by the digital particle image velocimetry (DPIV) ...  Read More
