Abstract  

The thermal behavior of Nafion-117 membranes was investigated by thermogravimetric analysis (TG) and differential scanning calorimetry (DSC). TG measurements revealed that the mechanism of thermal degradation of a Nafion membrane in the acid form is different from that of Nafion in the sodium form. The DSC curves for the first heating, for both acid and salt forms, display two endothermic peaks, near 120 and 230°C. The high-temperature peak was assigned to the crystalline domains melting in Nafion, and the low-temperature peak was attributed to a transition into ionic clusters, since this transition exhibits significant changes depending on the nature of the counterion and the degree of hydration.

Experiments were carried out with wheat varieties GK Garaboly, GK Kalász, GK Verecke, GK Petur sown at the Öthalom experimental station of the Cereal Research Non-Profit Ltd. in monoculture, in a four-parallel random block design. NPK fertilizer treatments of different level were combined with Artea + Amistar Xtra fungicide treatments of increasing doses and spectrum.The fertilizer and fertilizer + fungicide treatments had a statistically reliable effect at the 0.1% level on the technological water absorption only while it was indifferent on the values such as wet gluten content, gluten spreading, baking value and falling number. On annual level reliable treatment × variety interactions could be detected for each characteristic compared to control.Increasing fertilizer doses tendentiously improved the values of wet gluten, baking value and technological water absorbance. In the case of certain treatment combinations, however, these values exhibited a tendentious decrease as the counter-effect of fungicides applied at the heading stage of development. Our results revealed that the baking quality of grains was determined by the common effect of various doses of fertilizers and fungicides Artea and Amistar Xtra applied at heading. This counter-effect proved to be unfavourable in the case of certain baking characteristics.Six different alleles or allelic pairs were revealed in the sample of genotypes — 1, 2* (locus Glu-A1), 6 + 8, 7 + 8 and 7 + 9 (locus Glu-B1) and 5 + 10 (Glu-D1). Quality scores for the wheat cultivar varied from 8 to 10. Cultivar GK Kalász had the highest quality score 10.
