Environmental characterisation of foundry sludge (FS) and the stabilised/solidified (S/S) derived products has been performed according to the leaching behaviour. Portland cement and lime have been used as binders and foundry sand fines, activated carbon and black carbon have been used as additives in the S/S processes. The results of the characterisation(More)
ABSTRACT Deformation disease of Gypsophila paniculata mother plants reduces cutting yields as much as 50% but does not kill the mother plants. In preliminary experiments, fertigation of G. paniculata mother plants with a 20:20:20 compound fertilizer (N, P, K, plus microelements) at an N concentration of 720 mg/liter reduced the expression of deformation(More)
An environmental problem of the foundry activities is the management of industrial waste generated in different processes. The foundry sludge from gas wet cleaning treatment that contains organic and inorganic compounds and a high content of water is an interesting example. Due to their characteristics, they can be managed using different(More)
Below its ordering temperature (TN = 90 K), bulk bcc Eu has a helical magnetic state with propagation vectors along the three equivalent 〈100〉 directions. In contrast, epitaxial (110)Eu films exhibit a unique magnetic ordering : the domain with a magnetic helix propagating along the in-plane [001] direction vanishes on cooling, at the expense of other(More)
The propagation of Nd long range magnetic order in the hexagonal and cubic sublattices has been investigated in double hexagonal compact Nd/Sm(001) superlattices by resonant x-ray magnetic scattering at the Nd L(2) absorption edge. For a superlattice with 3.7 nm thick Sm layers, the magnetic structure of the hexagonal sublattice propagates coherently(More)
The effects of the addition of ground maize straw, nitrogen compounds, ground lucern and water to soils incubated at 30 degrees C in Erlenmeyer flasks, on Azotobacter chroococcum growth have been studied. The results showed that the highest number of Azotobacter in soils treated with different percentage of ground maize straw without addition of nitrogen(More)
