contribution of setting to the study of characters and the main idea in e. brontes: wuthering heights and t. hardys: return of the native.
this thesis aims to adduce an unmitigated and comprehensive explication concerning the relationship of three significant elements of fiction: setting, chracter and theme. my research is basically placed on two outstanding novels of the 19th century: emily brontes wuthering heights and thomas hardys return of the native. my endeavour lies in studying the correlation among the three above-mention...
15 صفحه اولfrom linguistics to literature: a linguistic approach to the study of linguistic deviations in the turkish divan of shahriar
chapter i provides an overview of structural linguistics and touches upon the saussurean dichotomies with the final goal of exploring their relevance to the stylistic studies of literature. to provide evidence for the singificance of the study, chapter ii deals with the controversial issue of linguistics and literature, and presents opposing views which, at the same time, have been central to t...
15 صفحه اولDetermination of ultra trace amount Chromium in water samples with the 1-(2-PyridylAzo)-2-Naphthol, (PAN) by the bromate ion in sulfuric acid with kinetic spectrophotometric method
A new kinetic spectrophotometic method for the determination of trace amount Chromium (III) in Teareal samples has been described based on it s the catalytic effect on the oxidations of 1 - ( 2 –PyridylAzo ) - 2 - Naphthol, (PAN), by potassium bromated in sulfuric acid. The reaction is followedspec- trophotometrically by measuring the decrease in the absorbance at 469 nm. Under the optimumcondi...
متن کامل1-(Hydroxyiminomethyl)-2-naphthol
The title compound, C(11)H(9)NO(2), was prepared by a condens-ation reaction of 2-hydr-oxy-1-naphthaldehyde with hydroxyl-ammonium chloride in refluxing ethanol. An intra-molecular O-H⋯N hydrogen bond is observed. In the crystal structure, inter-molecular O-H⋯O and C-H⋯O hydrogen-bond inter-actions result in a two-dimensional network.
متن کاملCloud Point Extraction of Palladium as Chelate with 1-(2-pyridylazo)-2-naphthol Using Triton X-114 Prior to Determination in Real Samples by ETAAS
A pre-concentration and determination methodology for palladium in real samples at ultra-trace levels by 1-(2-pyridylazo)-2-naphthol (PAN) was developed. The analyte in the initial aqueous solution, acidified with HCl, was complexed with PAN and Triton X-114 was added as a surfactant. The surfactant-rich phase was diluted with concentrated HNO3 (65%, w/w) after phase separation. Then, the conce...
