Application of Experimental Design to Optimize the Synthesis of CdO Cauliflower-like Nanostructure Using Mechanochemical Method

Cauliflower-like nanostructure of cadmium oxide was synthesized by utilizing mechanochemical reaction followed calcination procedure for the first time. The design of experiment (DOE) by Taguchi method was used to study influence of the chosen factors and to consider optimum conditions of the experiments. The temperature of calcining, the duration of milling, the duration of calcining and react...

Cauliflower-like lesion on the buttock: a quiz. Pedunculated lipofibroma.

A 38-year-old heterosexual man presented with a bulky mass lesion on his left buttock. A small polypoid lesion had been noted in the area since his childhood. It had grown slowly but steadily to a size of approximately 3 cm. In the past 2 years, however, there had been rapid growth. He denied any history of trauma or infection. His family history was insignificant. The patient was otherwise in ...

Detection of napropamide by microwave resonator sensor using carbon nanotube – polypyrrole- chitosan layer

This paper presents the design and fabrication of proximity coupled feed disk resonator coated with Multi Walled Carbon Nanotubes (MWCNTs) and Polypyrrole-Chitosan (PPy-CHI) layers as a napropamide sensor. Computer Simulation Technology (CST) microwave studio was used to obtain the best design of disk resonator and feed line position in 5 GHz resonant frequency. Also, MWCNTs - PPy-CHI layers we...

effect of oral presentation on development of l2 learners grammar

this experimental study has been conducted to test the effect of oral presentation on the development of l2 learners grammar. but this oral presentation is not merely a deductive instruction of grammatical points, in this presentation two hypotheses of krashen (input and low filter hypotheses), stevicks viewpoints on grammar explanation and correction and widdowsons opinion on limited use of l1...
