With the growth and development of chemical plants, the amount of mercury released in wastewater has increased. Mercury in wastewater contains harmful compounds which are hazardous to the human health and living organisms. Therefore, its removal from wastewater is significant. There are various techniques or methods available for removing mercury from aqueous solutions. This study focused upon ...

The purpose of this paper is multi-objective optimization of refrigeration cycle by optimization of all components of the cycle contains heat exchangers, air condenser, evaporator and super-heater. Studied refrigeration cycle is compression refrigeration cycle of unit 132 Third refineries in south pars that provide chilled water for cooling refinery equipment's. Cycle will be performed by t...

Anterior encephaloceles have been extensively reported and classified. Most have occurred at the juncture of the anterior part of the sphenoid with the pars orbitalis of the frontal bone. This corresponds to the region of either the crista galli or the cribriform plate. Encephaloceles in this location are seen in the region of the glabella, medial orbit, or in the nasal cavity or nasopharnyx an...

The understanding of the dynamic behavior of distillation columns has received considerable attention because distillation is one of the most widely used unit operations in chemical process industries. This paper reports a dynamic simulation study of the possible distillation columns sequences of Dew pointing unit in the second phase of South Pars Gas Refinery. In this unit, three columns are u...

Sir, We appreciate the opportunity to respond to the comment by Xiang et al. (2013) on our review on interspecies differences in the pedunculopontine nucleus area. As exemplified by the data of Xiang et al. (2013) it is evident that the mesencephalic locomotor region compromises several distinct structures that are involved in initiation and inhibition of gait, and certainly the implications of...

Before cell division in many bacteria, the ParBs spread on a large segment of DNA encompassing the origin-proximal parS site(s) to form the partition assembly that participates in chromosome segregation. Little is known about the structural organization of chromosomal partition assembly. We report solution X-ray and neutron scattering data characterizing the size parameters and internal organiz...
