Leaves of Arabidopsis thaliana grown under elevated or ambient CO2 (700 or 370 micromol mol(-1), respectively) were examined for physiological, biochemical and structural changes. Stomatal characters, carbohydrate and mineral nutrient concentrations, leaf ultrastructure and plant hormone content were investigated using atomic absorption spectrophotometry, transmission electron microscopy and en...

A new finite element based simulation technique for mineral growth governed by the classical Cahn–Hilliard equation is presented. The particular format of the underlying Flory–Huggins free energy for non-ideal mixtures is characterized through a double-well potential. It allows for uphill diffusion driven by gradients in the chemical potential and thus provides the appropriate framework to simu...

The transport of fluids through the Earth's crust controls the redistribution of elements to form mineral and hydrocarbon deposits, the release and sequestration of greenhouse gases, and facilitates metamorphic reactions that influence lithospheric rheology. In permeable systems with a well-connected porosity, fluid transport is largely driven by fluid pressure gradients. In less permeable rock...

IN MANY PARTS of the world, symptoms of malnutrition or disease in livestock on certain areas have been traced to deficiencies of nutritionally essential mineral elements in the available forage. In some of these areas, before the causes of the difficulties were discovered and remedial measures taken, there were serious economic losses as the result of impaired productive capacity and death of ...

In this study, 321 winter and spring wheat genotypes were analysed for twelve nutritionally important minerals (B, Cu, Fe, Se, Mg, Zn, Ca, Mn, Mo, P, S and K). Some of the genotypes used were from multiple locations and years, resulting in a total number of 493 samples. Investigated genotypes were divided into six genotype groups i.e., selections, old landraces, primitive wheat, spelt, old cult...

We examined differences in the radioactive characteristics among the main minerals forming granite materials. Using a non-toxic high-density agent, minerals were separated from rock (granite-gneiss) and soil (weathered granite) samples. The natural radioactivity ((238)U and (226)Ra) and radon emanation fraction of the minerals were then studied by gamma-ray spectrometry. The radon emanation fra...

Improving the mineral concentrations of maize (Zea mays L.) will aid in reduction malnutrition low-resource households that consume maize-based meals regularly. The study’s objective was to compare how different soil amendments and heat-stressed environments affect grain yield maize. study involved (HS) non-heat-stressed (NHS) environments, three varieties (WE3128, WE5323, ZM1523), amendments. ...

The researches of cultivation winter wheat with application the biologically active substance potassium humate and nitrogen fertilizers different concentrations N 20 40 their interaction +GK showed that humate, without being a mineral fertilizer, increased crop capacity, content in grain, mass proportion grain protein, Grain nutrition quantity gluten were same as , had comparable values for pro...
