Uptake and Bioavailability of Copper after Liming of Alder Plantation
Jakl, M.; Kuneš, I.; Jaklová Dytrtová, Jana; Balaš, M.; Tlustoš, P.
2010 - Czech
The availability of copper in mountain forest soil (7 years after fertilization) afforested with alder (Alnus incana (L.) Moench) was explored using the diffusive gradient in thin films (DGT) technique compared with its water soluble fraction in soil and its total content in plant compartments. DGT seems to be more promising method determining elements availability; it corresponds with total concentrations in alder tissues closely than contents in water extract. Fertilization increased concentration of Cu in the thinnest root fraction; its total amounts in other tissues of fertilized alders were significantly higher than in the control. Přijatelnost mědi na horské lesní půdě (7 let po hnojení) zalesněné olší (Alnus incana (L.) Moench) byla zkoumána pomocí techniky difúzního gradientu v tenkém filmu (DGT) v porovnání s její vodorozpustnou frakcí v půdě a obsahem v jednotlivých částech rostlin. DGT se zdá jako slibnější metodou stanovení přijatelnosti prvků, koreluje s celkovými koncentracemi v rostlinách více než koncentrace ve vodném výluhu půdy. Hnojení zvýšilo koncentraci Cu v nejtenčí kořenové frakci; celková množství v ostatních frakcích hnojené olše byly signifikantně vyšší než u kontroly.

Chemical factors affecting the taste and medicinal activity of wine
Harmatha, Juraj
2010 - Czech
The wine is presented as a complicated multi-component, and permanently varying (maturing) natural product, with unique properties, acquired from several sources, e.g. the grape origin, the growth locality, the enological processes, as well as the qualified evaluation with a feedback to all factors shaping the character and quality of wine. Chemical components are regarded as generators of perceivable sensory (taste) properties of wine, as well as providers of its pharmacological effects and medicinal value, qualifying wine as active functional food additive (nutraceutical) with a significant impact on health. Víno je neustále a průběžně se měnící přírodní produkt, který má své jedinečné vlastnosti pocházející z několika zdrojů, k nimž patří jeho původ, enologický postup zpracování, proces školení, jakož i kvalifikované hodnocení se zpětnou vazbou na všechny faktory, které utváří charakter a hodnotu vína. Pojednává se zde o chemické podstatě chuťových aspektů, a o možnosti jejich ovlivnění. Obsahové (extraktivní) látky jsou zde představeny i jako nositelé léčivých účinků, které staví víno do role aktivního potravinového doplňku (nutraceutika) s blahodárným vlivem na zdraví.

The quality of wine from the aspect of a chemist and sommelier
Harmatha, Juraj
2009 - Czech
The wine substances are regarded not only as providers of perceivable sensory properties, but also as a basis of medicinel effects of wines. The wine is presented as an active functional food additive - nutraceutical, with significant impact on health. Pojednáno je o obsahových látkách nejen jako o nositelích senzoricky vnímatelných vlastností, ale jako o nositelích léčivých účinků vína. Víno je představeno jako aktivní potravinový doplněk - nutraceutikum, s výrazným vlivem na zdraví.
