Volatiles Distinguishing the European 'Conference' and the Asian 'Yali' Pears Stored at Different Post-Harvest Temperatures

A total of 124 identical volatile aromatic compounds were identified during storage of the European 'Conference' and the Asian 'Yali' pear cultivars in different temperature conditions. Only 5 volatiles were statistically differentiated in both cultivars by means of successive multinomial logistic regression: 3-methylbutan-1-al, 2-methylpropyl acetate, 2-methoxy-4-vinylphenol, ethanol, and eugenol. Significant statistical data obtained by sequential multinomial logistic regression developed by the principal component analysis (PCA) procedure and distinguishing the different 'Conference' and 'Yali' pears storage regimes were dimensionless in themselves. The PCA components were expressed as linear combinations of selected variables necessary to distinguish the cultivars. The eigenvalues of the first three PCA components differentiated the storage regimes. For each principal components were selected volatiles with a probability higher than 0.4. Combinations created from PCA components were shown using clusters distinguishing the pear storage conditions used. Analytical data from SPME-GC/MS such as concentration (ng kgMINUS SIGN 1) demonstrated multiple and order-of-magnitude differences between the 'Conference' and 'Yali' pears. The 'Yali' cultivar exhibited significantly higher concentrations of eugenol.O

Influence of nitrogen injection application on zinc and iron uptake by winter wheat and spring barley

Influence of CULTAN method (Controlled Uptake Long Term Ammonium Nutrition) on the iron and zinc uptake by winter wheat (Triticum aestivum L.) and spring barley (Hordeum vulgare L.) was observed at four-year small-plot field experiments under conditions of the Czech Republic. No significant differences in iron and zinc concentration in grain of winter wheat as well as spring barley between conventional and CULTAN treatment were found. Neither increased supply of nitrogen fertilizer nor sulphur containing fertilizer resulted in significant differences in iron and zinc concentration in grain of winter wheat as well as spring barley at both nitrogen nutrition systems. No significant differences in sulphur concentration in aboveground biomass of winter wheat and spring barley between conventional and CULTAN treatment were recorded. Iron and zinc harvest index were not influenced by the CULTAN system. Because of no significant differences in iron and zinc concentration in grain of winter wheat as well as spring barley between conventional and CULTAN treatment, it can be assumed that nitrogen is taken up by CULTAN-treated plants in nitrate form

Comparison of point injection and top-dressing application of nitrogen fertilizers with sulphur addition in winter rape (Brassica napus L.) in the Czech Republic

In this paper, we are analyzing the yield and yield parameters of winter rape, fertilized using CULTAN system (Controlled Uptake Long Term Ammonium Nutrition) in comparison with top-dressing application of nitrogen fertilizers, which were studied on Haplic Luvisol over 5 years. No significant differences in seed yields between the two systems of fertilization were observed in 2008, 2009 and 2011. The effect of sulphur on a higher seed yield was proved in 2010 and 2012. The seed yield was higher by 11.4% in the treatments with sulphur amendment regardless of the system of fertilization in 2010. The seed yield was higher by 18.2 % in the CULTAN treatment with sulphur adittion in comparison to CULTAN treatment with no sulphur added in 2012. Nitrogen supply was ample in the first flowers open growth stage of winter rape in 2009, 2010 and 2012. The plant height was significantly lower after CULTAN method and as well as higher values of 1000 seed weight were recorded in comparison to top-dressing application in 2009. Nitrogen uptake by seed dry matter was the highest in the year 2009, which corresponds to the achieved seed yields this year

Idea univerzity z české perspektivy

Title in English: The idea of a university from a Czech perspective: Conversations with Jiří Hanuš The aim of this book is to explore the ‘idea of a university’ and specific modern developments both abroad and in the Czech Republic through dialogues with prominent Czech academics: Stanislav Balík, Petr Dvořák, Petr Fiala, Pavel Floss, Jiří Hanuš, Petr Horák, Jakub Jirsa, Jiří Lach, Jiří Macháček, Tomáš Machula, Dominik Munzar, Ivana Noble, Jan Sokol, Daniel Soukup and Kateřina Šimáčková

Dobrodružství historické interpretace

Title in English: The Adventure of Historical Interpretation This collection of nineteen essays written by prominent historians demonstrates the diversity of academic approaches. Their work with historical sources, the foundation stone of research, is combined with ethical and aesthetic decision-making, which forms an indisputable part of their work. This is often surprising - both for the readers and themselves. It represents a great intellectual adventure. They cannot invent sources or set arbitrary rules, plots, and twists and turns, as a novelist might. However, they can write a scientific work which is the result of a creative approach

The Olympic Games in Barcelona 1992 as a factor of changes in Catalan nationalistic discourse of political parties

Interrelation between sports and politics in the specific case of the Olympic Games in Barcelona in 1992 offers a wide range of opportunities to strengthen nationalist tendencies of the Catalan society. This thesis examines how the organization of this event affected the development of Catalan nationalistic discourse of political parties. These changes are analysed on two levels. The first level is the evolution over time - the thesis compares the periods before and after the Olympics and looks at trends across each period. The second level is the development in the level of debate - the thesis looks at the category of political parties, at the category of Catalan politics and at the category of the Spanish nationwide politics, while it analyses the moves of the topics and trends across the levels. Thus, the thesis examines trends of the political discourse in the electoral programs, in speeches at annual meetings at the level of the Catalan parliament and in speeches at annual meetings at the level of national Spanish Parliament. The basic parameters of the research work are themes of language policy, cultural policy, the issue of state structure juristic reform, linguistic forms of the discourses and relation to the Olympic Games. The main basis of this work is the contribution of sporting events..

Spanish sport in era of francoism and its political exploitation

The thesis "Spanish sport in era of francoism and its political exploitation" deals with the use of sport in different policy sectors of Franco's regime. It examines how much sport reflected official state policy. The first part focuses on internal sport organization, which shows the domination over the entire sport sector. The second part of the thesis deals with the reflection of francoist internal policy in sports. Thus it analyses physical education as a tool for political indoctrination and top-level sport as a device to maintain social political passivity. Further, it analyses the centralist policy of the regime represented by the support of selected sport clubs and orientation of sport events to the capital city - Madrid. The third and final part defines use of sport in foreign policy. The thesis as a whole concludes that the projection of regime policy in sport is completely natural and that the regime didn't depart of its overall policy while using sport
