Voltammetric Determination of Chili Peppers Pungency using Phospholipid Modified Glassy Carbon Electrode\n
Skopalová, J. ; Rajcová, A. ; Vokounová, D. ; Navrátil, Tomáš
The aim of this study was to develop a simple method for evaluation of the pungency in chili peppers with a glassy carbon electrode modified using phospholipid membrane prepared from asolectin. For these purposes cyclic voltammetry (CV) and differential pulse voltammetry (DPV) have been used. A few different methods have been tested: direct method, transfer method on unmodified and modified electrode, using standard addition method as well as calibration curve method. A statistically significant correlations with the results of the reference HPLC method have been found in case of voltammetric methods, especially in DPV with asolectin modified electrode.
Preventive Conservation of DOP Gellatine Prints
Vokounová, Daniela ; JŮN, Libor (advisor) ; SILVERIO, Robert (referee)
Work solves the problem of long-term storage DOP želatinostříbrného positives. The first part focuses on identifying material composition based on the description of the production and manufacturing process. In the second part defines the factors influencing climate in the depository, description and causes harm DOP želatinostříbrného positives and fundamental questions of the issue of preventive care. Work is a study of contemporary literature technological DOP in the range of 1880-1950 years, the issue of preventive care is handled by specialized research studies domestic and foreign literature, between the years 1970-2015. Processed were books, articles in professional periodicals, anthologies of texts, and grant research reports, guidelines and standards. The result is putting conditions for long-term storage DOP, current recommendations for long-term storage DOP želatinostříbrných positives by comparing the approaches of professional institutions focusing on preventive care for the photography.
