Spectrophotometric Determination of Nitrate in Vegetables Using Phenol

A rapid and sensitive spectrophotometric method for the determination of nitrate in vegetables is described. The method is based on the measurement of the absorbance of yellow sodium nitrophenoxide formed via the reaction of phenol with the vegetable-based nitrate in presence of sulphuric acid. The analytical concentration of the acid has marked effect on the nitrate determined. The colour development was rapid and remained stable overnight. Analysis of six vegetable samples containing nitrate gave satisfactory mean recoveries of 76 to 123% in 18 determinations. The proposed method is reproducible and sensitive to lower level concentrations

A l'entorn de l'adquisició de la sintaxi i del seu estudi

This article reflects upon new observations and old concepts related to the acquisition of syntax by examining the strengths and weaknesses of research in acquisitional syntax. Two of the strengths are the interdisciplinary nature of child acquisitional studies and the potential dialogue between research in theoretical syntax and acquisitional syntax. A weakness, possibly the result of excessive specialization, is the lack of real dialogue in general debates related to central foundational concepts in syntax, such as the poverty of stimulus argument or the conception of Universal Grammar. This article reviews two recent publications that touch upon these topics and discusses the results in light of research in early syntax within the generative paradigm
