Quantification of Nicotine in Commercial Brand Cigarettes HOW MUCH IS INHALED BY THE SMOKER?
(JOHN WILEY & SONS INC, 2010)
The main objective of this experiment is to determine the amount of nicotine in commercial brand cigarettes by means of a nonaqueous acid-base titration. A simple glass device simulating a smoker is proposed, which allows ...
Nitrogen and potassium fertilization affect apple fruit quality in southern Brazil
(TAYLOR & FRANCIS INC, 2008)
Nitrogen (N) and potassium (K) are usually found in higher concentrations than other macronutrients in apple (Malus x domestica Borkh) fruits and are most frequently associated with changes in fruit quality. The aim of ...
