Graphical Abstract:
 The complexes of general formula Cu(H2L) (II); [CuLn(L)(NO3)(H2O)n] (where H4L=N,NI-bis[2- hydroxy(3-
carboxynaphtalidene)]ethylenediamine; Ln: Nd, n=6 (III); Eu, n=4 (IV); Gd, n=6 (V) have been synthesized a
nd investigated by different methods (IR spectroscopy, TG analysis and magnetochemistry). The coordination set of complex generators are Cu(N2O2) and Ln(O8-9). The effective magnetic moment values, μeff, at 300 K are: 1.78 (II), 3.22 (III), 6.44 (V) B.M. The temperature dependence (300-2 K) of magnetic susceptibility of [CuNd(L)(NO3)(H2O)6] indicates the antiferromagnetic interaction between metal ions.

Graphical Abstract: 
The paper summarizes the research results on development national emissions factor for the Greenhouse Gas Inventory (GHGI) Source Category “6A Solid Waste Disposal on Land”. The obtained results offer the opportunity to improve the Intergovernmental Panel for Climate Change (IPCC) methodologies and Emission Factors for assessing the GHG emissions originated from waste sector. The article contains relevant information on composition of landfill gases at managed and unmanaged solid waste disposal sites, as well as the municipal solid waste composition results, investigated during one year in the Republic of Moldova: from autumn, 2004 to summer, 2005.

Graphical Abstract: 
The aim of this work is the study made for obtaining iodized oil that would satisfy the requirements in iodine for human body. The sunflower oil is a product with the most important value, thus the production of oil fortified with iodine would be a cheap and accessible option. These studies indicate that lipids present an important vehicle for the fortification with iodine. Eradication of the iodine deficiency may be realized not only by injection of the iodinated oil, but also by its use as an ingredient for the formulation of different food compositions. This method, complementary with the iodinated salt, would allow the increase of the efficiency of the prophylactic undertaken measures, because is based on the use of vegetal material – sunflower oil; it is cost-efficient and does not require substantial investments.
