in this work, magnetically separable zno-znfe2o4-ppy nanocomposite as an efficient adsorbent was synthesized by two steps. at first, zinc oxide (zno) and znfe2o4 nanoparticles were synthesized using simple and facile precipitation method. then, zno-znfe2o4 mixed oxide was modified by polypyrrole (ppy). the adsorbent was characterized by x-ray diffraction (xrd), fourier transform infrared (ft-ir...

abstract purpose: skeletal staining is a way to study the effect of many chemical or herbal substances on development of bones and cartilages in order to record the level of probable deformity.this article aimed to present a modified protocol to make all skeletal studies on laboratory animals possible. materials and methods: the important notes about skeletal staining were fixing by ethanol and...

Random Early Detection (RED) is one of the most commonly used Active Queue Management (AQM) algorithms that is recommended by IETF for deployment in the network. Although RED provides low average queuing delay and high throughput at the same time, but effectiveness of RED is highly sensitive to the RED parameters setting. As network condition varies largely, setting RED's parameters with fixed ...

In the recent years, there is evidence of training a red type of zebrafish which differs from wild-type in body color. There is not any document how it reaches to the ornamental fish farms of Iran but at first, it was a doubt it belongs to a morphotype or genetic modification (GM). First of all, a set primer was designed to validate zebrafish species. Mitochondrial 16srDNA was selected and ampl...
