Is Child like Parent? Educational Attainment and Ethnic Origin The speed at which immigrants assimilate is the subject of debate. Human capital formation plays a major role in this discussion. This paper compares the educational attainment of second generation immigrants to those of natives in the same age cohort. Evidence using a large German data set suggests ethnicity does matter: the size o...
In a recent study by Kier, Cheng and Testa, simulations were carried out to monitor and quantify the emergence of a collective phenomenon, namely percolation, in a many-particle system modeled by cellular automata (CA). In the present study, the same setup was used to monitor the counterpart to collective behavior, namely the behavior of individual particles, as modeled by occupied cells in the...
Alkaline pH values and bicarbonate greatly reduce the mobility and uptake of Fe, causing Fe deficiency chlorosis. In the present work, the effects of pH and bicarbonate on the uptake and accumulation of Fe in the roots of cucumber were studied by Mössbauer spectroscopy combined with physiological tests and diaminobenzidine enhanced Perls staining. Mössbauer spectra of Fe-deficient cucumber root...
Protein fractionated from alfalfa exhibits promising properties for exploitation as food ingredient. However, further knowledge and improvement of the functional is essential to increase potential commercial use. This might be obtained by acid or alkaline pH shift processes. The effect shifting compared controls (buffer solutions) at different pH-values were investigated concerning protein solu...
