Deformation of the Earth’s surface by local mass loading and uploading effects

Mojzeš M., Kollar P, Valko M.

Reports on Geodesy

2012

z. 1/92

191--200

The mass of a building influences a deformation of the Earth’s surface up to long distance from area of realization. The elastic and rheological effects of settlement are modeled by different methods presented in the many scientific papers. More deeply knowledge of mechanical properties of materials and modern computer equipment allow construct very precisely model reaction of the Earth surface on loading effects in time. Geodesists and geophysicists need to know this laws of deformation and theirs time evolution for design of control geodetic networks and for analysis of repeated control measurements of horizontal and vertical time series. The presentation contents the mathematical modeling of the Earth elastic surface deformation caused by loading and unloading effects caused by a mass.

Spectral and thermal properties of copper(II) complexes with methyl-3-pyridyl carbamate

Mojumdar S., Melnik M., Valko M.

Polish Journal of Chemistry

1999

vol. 73 nr 3

457-463

Thermogravimetry (TG), differential thermal analysis (DTA), infrared (IR), electronic, EPR spectra and other analytical methods have been applied to the investigation of the thermal behaviour and structure of the compounds [Cu(ac)2(mpc)]2×2CH3OH (I), Cu(Clac02(mpc) (II), Cu(Cl2ac)2(mpc)2 (III) and Cu(Cl3ac)2(mpc)2 (IV) (where ac = CHCOO-, Clac = ClCH2COO-, Cl2ac = Cl2CHCOO-, Cl3ac = Cl3CCOO- and mpc = methyl-3-pyridyl carbamate). The solid phase intermediate and resultant products of thermolysis had been identified. The possible scheme of decomposition of the complexes is suggested with as a final product, CuO. IR data suggest a unidentate coordination of carboxylate to copper(II). Methyl-3-pyridyl carbamate was coordinated through nitrogen atom of its heterocyclic ring in complexes I-IV. EPR spectra suggest a diametric structure of complex I and manometric structure of complexes II-IV.
