the aim of this paper is eliminating cr(vi) by natural hap. hap is a inexpensive material which is used from bovine critical bone ash in order to remove heavy metal ions like cr(vi). some experiments in different ph are performed (ph=2,3,7). maximum adsorption was appeared at ph=2, dosage=0.3 gr, c0=10 mg/l. cr(vi) removal depends on ph value and initial amount of cr(vi) result of experiments w...
the main purpose of this research was to:1.develop a coking model for thermal cracking of naphtha.2.study coke inhibition methods using different coke inhibitors.developing a coking model in naphtha cracking reactors requires a suitable model of the thermal cracking reactor based on a reliable kinetic model.to obtain reliable results all these models shall be solved simultaneously.for this pu...
Assessment of the cellular effects of natural and/or synthetic products is one of the major goals in biological experiments. This assessment may be conducted at different levels; cellular viability, cellular biological activity, and cellular structure and morphology. Different assays are available for any of above purposes. It is becoming of a routine exercise to apply any of these assays, and ...
This paper provides a survey of recent experimental work in economics focussing on social and economic networks. The experiments consider networks of coordination and cooperation, buyer-seller networks , and network formation.
alkaline hydrolysis of ethyl acetate is essentially an irreversible and second order reaction. industrial importance of the reaction product, sodium acetate, necessitate for process improvement in terms of maximum conversion and economical usage of raw materials. statistical design of experiments was utilized to enhance conversion in both batch and plug flow reactors.a full two level factorial ...

In this study, the experimental analysis on the bare hull resistance coefficient of submarine at snorkel depth is represented. The experiments are conducted in marine laboratory of Admiral Makarov University. The results are presented for surface condition and snorkel condition. Snorkel depth is regarded equal to one diameter of submarine hull beneath the water surface as usual in submarines. P...
A Rectangular Dielectric Resonator Antenna (RDRA) is theoretically analyzed using the Conventional Dielectric Waveguide Model (CDWM), numerically simulated using the High Frequency Structure Simulator (HFSS) based on the Finite Element Method (FEM) software package and experimentally investigated with the consideration of the fundamental mode TE 111. Antenna parameters under investigation inclu...
