exploring motivation and english test preparation strategies of iranian pre-university candidates during and at the end of test preparation period for konkur examination

the current study aimed at investigating the relationship between motivation and test preparation strategies (tpss) used by iranian pre-university students in their preparation period for the university entrance exam (uee). due to the importance of uee in iran, this study also attempted to show its impact on these two important variables. to this end, 100 pre-university students in an iranian p...

Development of ultrasound-assisted emulsification microextraction for the determination of trace zinc and copper by flame atomic absorption spectrometry

In this work, we developed a method based on ultrasound-assisted emulsification microextraction (USAEME) for the determination of zinc and copper by flame atomic absorption spectrometry (FAAS). The method is based on the use of the organic solvent carbon tetrachloride (CCl4) as an extraction solvent. In order to obtain a high enrichment factor, the effect of different parameters affecting the c...

Estimation of serum copper and zinc levels in oral submucous fibrosis: an atomic absorption spectroscopic study.

BACKGROUND AND OBJECTIVES Biochemical derangements of microelements although reported in oral cancer is poorly understood in oral submucous fbrosis (OSMF). Hence, the present study was carried out to estimate and compare the serum copper and zinc levels among different histopathological stages of OSMF with that of healthy controls. MATERIALS AND METHODS Thirty histopathologically diagnosed ca...

Methods compared for determining zinc in serum by flame atomic absorption spectroscopy.

We compared two methods for determination of serum zinc by flame atomic absorption spectroscopy. The first involved 10-fold dilution of serum with water; the second, deproteinization of serum with trichloroacetic acid. Analytical recovery of Zn2+ added to serum averaged 99.3 and 99.9%, respectively, by the two methods, but measured concentrations were consistently greater by the second method [...

Preconcentration of Cu(II)with magnetic nanocomposite sorbentsprior to determination by Flame Atomic Absorption Spectrometer

A simple, highly sensitive, accurate and selective method for determination of trace amounts of Cu2+ in water samples .In this paper, Chitosan was used to encapsulate nano-Fe3O4 and produce a nano-Fe3O4-CHITOSAN sorbent based new sorbent was prepared. This was treated with ethylenediamine (ED) in another solvent-free procedure for the formation of a novel nano-Fe3O4-Chitosan-ED.Flame atomic abs...
