Introduction: Bioremediation convertssoils pollutants to safe and non-toxic substance through metabolic activities of microorganisms. This research was conducted to evaluate the effect of bacteria on removal of phenanthrene and anthracene from polluted soils using chicken manure as an auxiliary substrate. Materials and Methods: First, uniformly-graded soils were transferred to the pilots, then...

An< accurate, stable and very fast corner finder (for feature based vision) has been developed', based on a novel definition of corners, using:no image derivatives. This note describes the algorithm and the results obtained from its use.

Polycyclic aromatic hydrocarbons (such as, anthracene, benzo[a]pyrene and so on) are non-polar, hydrophobic compounds, which are not ionized. They are only slightly soluble in water. They are very dangerous compounds in the environment. The single-walled carbon nanotube (SWNT) is used for removal and conversion of anthracene to low-risk products. In this study, electron transfer between anthrac...

Anthracene fibers are grown inside a microstructured quartz matrix to form a multicore optical fiber for X-ray detection. A modified fiber growth method for single crystal anthracene from the melt via the Bridgman-Stockbarger technique is presented. The anthracene fiber is characterized by using spectrophotometry, Raman spectroscopy, and X-ray diffraction. These results show the anthracene grow...

polycyclic aromatic hydrocarbons (pahs) such as anthracene, naphthalene, and phenanthren are the most toxic and carcinogenic pollutants which cause severe damages on soil and water resources. in order to remove these materials, biological methods and using potential of local microorganisms of oil contaminated soils are preferred because of cheapness and availability. existing soil microorganism...

A common impurity of 7,12-dimethylbenz[alpha]anthracene was more effective than 7,12-dimethylbenz[alpha]anthracene in inducing morphological alterations, and in causing an increase in glucose uptake, DNA synthesis and cell number in chick-embryo fibroblasts. Gradual morphological transformation follows the increase in DNA synthesis after 2 days when either primary or secondary cultures are trea...

Cultures of the ligninolytic fungus Irpex lacteus incubated in a nutrient liquid medium degraded more than 70% of the initially applied benz[a]anthracene within 14 days. At the first step of metabolization, benz[a]anthracene was transformed via a typical pathway of ligninolytic fungi to benz[a]anthracene-7,12-dione (BaAQ). The product was further transformed by at least two ways, whereas one is...

Introduction: Anthracene is one of the chemical and persistent pollutants released into the environment and the food chain causing irreparable damage to the immune system. This study aimed at removing anthracene from aqueous solutions using modified magnetic nanoparticles.   Materials & Methods: Initially, Fe3O4 nanoparticles were synthesized with silicon dioxide shell and then modified with ...

A model for computing image ow in image sequences containing a very wide range of instantaneous ows is proposed. This model integrates the spatio-temporal image derivatives from multiple temporal scales to provide both reliable and accurate instantaneous ow estimates. The integration employs robust regression and automatic scale weighting in a generalized brightness constancy framework. In addi...
