Dendrological inventory and tree management of the academic campus of the University of Warmia ans Mazury in Olsztyn was prepared in 2008. Analysis covers the area of the oldest part of the campus, named Kortowo I (53,5 hectares). During the study, 7676 dendrological objects were inventoried. Documentation was made in the standard that was current for that time, and now all data has been entered into the GIS system. This form of data recording has expanded the possibilities of processing data sets and visualizing ...

A large number of structural damages reported during the past decades around the world associated with a high geotechnical risk have highlighted the major attention that should be given to the expansive soil category in engineering practice. For avoiding or mitigating the effects of clay expansiveness on civil engineering structures before construction, the identification of soil parameters related to swelling behavior is considered essential in solving geotechnical engineering problems. This paper aims to analyze...

Petroleum and its derivatives are the main source of energy for industry and domestic consumption. Petroleum hydrocarbons are based on multiple carbon bonds that develop intense and raised complex structures when they bound with other characteristic molecules, hence the latest hydrocarbons have variety of forms and consist of short, medium and long aliphatics, aromatics and polycyclic aromatic hydrocarbons of different proportions. The accidental release of these hydrocarbons into the environment represents a majo...

The rivers of the Northern part of European territory of Russia (ETR) contain large amounts of organic matter. This is due to natural features of the area (short cool summer, high wetlands, large areas of forests and features of soil formation), and to specificity of the anthropogenic impact. One of the largest rivers of the Northern ETR is the Northern Dvina River, flowing into the Dvina Bay of the White Sea. A general study of the organic carbon content in the bottom sediment of the Northern Dvina River mouth ar...

The aim of this paper is to highlight the degree of connection between the kinematic and dynamic characteristics of sports technique used in acrobatic elements and the performances achieved by junior gymnasts in balance beam events. For this purpose we used the following research methods: bibliographic study of the specialized literature, pedagogical observation, video-computerized method, using ?Pinnacle Studio? and ?Physics ToolKit? programs, method of movement postural orientation and evaluation of sports techn...

The use of synthesis chemical substances in agriculture for increasing agricultural production and ensuring food across the globe is a process that has as a reverse negative effects on the environment and human health. According to the research conducted widely it has proved that, these synthesis substances that sometimes are toxic (pesticides, herbicides, etc.) have a negative influence on human health ultimately, also by polluting the environment, which represents the biggest challenge of the humanity today - cl...

In Banatului Plain area (western Romania) the grassland vegetation is represented by steppe and forest steppe. From the past, most of the land was cultivated and nowadays grasslands are present in the plain only in the vicinity of the inhabited area for the use of the grazing animals of the community during the vegetation season. Many times the steppe grasslands are characterised by an increased alkalinity of the soil that determinates the existence of the halophytic vegetation sward. The plain is mostly intensive...
