Zeolites have been increasingly used in various application areas such as industry, agriculture, environmental protection, and even medicine. Although, there are no certain figures on the total amount of these minerals the world, some countries e.g. Cuba, USA, Russia, Japan, Italy, South Africa, Hungary and Bulgaria, have important reserves and production potentials. According to reports of 200...
The purpose of our experiments was to examine the effect of different soil covering matters (livestock manure, straw and crushed pine bark) on the quantity of some microbial groups (total bacteria, aerobic cellulolytic bacteria, microscopic fungi) occuring in soil. During two years samples were taken from a Cider apple plantation at the Fruit Production Research and Advisory Kht, Újfehértó four...
Conservation tillage systems provide optimum conditions to reduce soil erosion and increase surface soil organic matter. This experiment was established with the longterm goal of developing conservation tillage systems that use either chemical inputs to produce vegetables and control pests, or legume cover crops, biological pesticides, and tillage to provide plant nutrition and control pests. T...
ed by the ether oxygen of oxanorbornene and dehydration can occur along the pathway illustrated in Figure 7.10. Figure 7.10 Proton transfer from adsorbed DMF to the cycloadduct. At the same time, proton transfer of the acidic H of the adsorbed DMF complex to p-xylene is neither energetically favorable (∆G = +27.6 kcal/mol) and has a significant energy barrier (Ea = +26.6 kcal/mol). Once the pro...
Electrorefining of metals was developed in the second half 19th century [...]
Organic production and consumption provide a delineated food system that can be explored for its potential contribution to sustainable diets. While organic agriculture improves the sustainability performance on the production side, critical reflections are made on how organic consumption patterns, understood as the practice of people consuming significant amounts of organic produce, may also be...
