The paper deals with the themes of the Earth's orientation and rotation. The parameters of the Earth's orientation can be determined by several methods. The emphasis in this paper is the influence of ocean tides to determine the parameters of the Earth's orientation with one of the space-geodetic techniques, called Very long baseline interferometry...

Condition and quality of the lawn grass and flowering plants is important indicators of the level of landscaping and the urban environment. Copper ions significantly reduce the quality of ornamental plants. The aim of this study was to assess phytotoxicity of copper for Chrysanthemum carinatum, Festuca rubra and Agrostis stolonifera.High contaminat...

The adsorption of Zn(II) and Cu(II) onto siderite (S) and kaolin (K) and adsorption of As(V) onto bentonite (B) was studied. The chemical modification – precipitation of MnO2 on the kaolin (KM) and siderite (SM) surface was used to improve the adsorption properties of natural materials for their application in columns. In the batch tests the higher...

Efficiency of trigonometric levelling method for height differences determination is better than those determined by geometric levelling but its accuracy is significantly lower. Development of accuracy of geodetic instruments increases possibilities for improvement accuracy of trigonometric levelling.However, air refraction appears as ultimate limi...
