Riboflavin-binding protein (RfBP) was isolated, purified and characterized from Coot (Fulica atra) egg. The RfBP was purified using DEAE-Sepharose ion exchange chromatography followed by gel filtration on Sephadex G-100. The purity of the proteins was judged by SDSPAGE. The protein migrated as a single band on SDS gel with a molecular weight of corresponding to nearly 29 Kd.
Background and purpose: The Common Coot (Fulica atra) is an abundant aquatic bird in North of Iran and is anticipated to be a good indicator for metal pollution on north wetlands of Iran. The aim of this study was to determining metals concentration in water, sediment samples and two organs of Common coot (liver and kidney). Materials and methods: This study was tested on water, sediment and 3...
American coot (Fulica americana) flocks exhibit water surface (two-dimensional) collective dynamics that oscillate between two primary phases: a disordered phase of low density and non-uniform coot body orientations; a synchronized phase characterized by high density, uniform body orientations and speed. For this small-scale study, data was obtained for flocks of 10 to ~250 members for these ph...
The purpose of this paper is to address an urgent operational issue referring optimal power flow (OPF), which associated with a number technical and financial aspects relating issues environmental concern. In the last few decades, OPF has become one most significant in nonlinear optimization research. generally improves performance electric distribution, transmission, production within constrai...
background: present study was carried out in north of iran to investigate the concentration of mercury (hg) as one of the most toxic metals in tissues of two species of birds. methods: in this study, 15 birds from coot (fulica atra) and 18 birds from cormorant (phalacrocorax carbo) were hunted in anzali and gomishan wetlands. data-analyses carried out using spss software version 17 licenced by ...
We isolated highly pathogenic avian influenza virus (H5N8) of clade 2.3.4.4 from the common coot (Fulica atra) in Egypt, documenting its introduction into Africa through migratory birds. This virus has a close genetic relationship with subtype H5N8 viruses circulating in Europe. Enhanced surveillance to detect newly emerging viruses is warranted.
