At the early stages of the Internet, it was only considered to be a communication tool. Nowadays, this network not only shaped itself into a new form of social life, but also brought about great changesin lifestyle. This is why, the Internet certainly has an impact on individual’s development. In the virtual world, people can shape their identity into whatever they want but it does not come without dangers. This article focuses on the self-image and identity of the youth in the modern media era and dilemmas they face in the process of identity construction.

We wczesnych fazach Internetu był on traktowany jedynie jako narzędzie służące do komunikacji. Dziś tego rodzaju sieć globalna nie tylko kształtuje się w nową formę życia społecznego, ale także powoduje ogromne zmiany w stylu życia, dlatego też Internet niewątpliwie ma i będzie miał wpływ na rozwój jednostek. W świecie wirtualnym ludzie mogą kształtować swoją tożsamość w dowolny sposób, ale nie jest to coś pozbawione niebezpieczeństwa. W artykule skupiono się na obrazie siebie i tożsamości młodych ludzi w dobie współczesnych mediów, a także na trudnościach, jakie napotykają w procesie konstruowania tożsamości.

Anisodus tanguticus (Maxim.) Pascher is an important Tibetan folk medicine and the source of tropane alkaloids (TAs) grown in Qinghai-Tibet Plateau. There are marked differences in quality of A. tanguticus from geographic areas. The aim of present research was to establish a method for the quantitative analysis of TAs coupled with chemometrics analysis to trace geographical origins. Qualitative analysis of TAs in A. tanguticus was carried out using ultra-performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry and quantitative analysis of TAs in different plant organs from different geographical origin was achieved. Contents of TAs were subjected to the principal component analysis, and orthogonal partial least-squares discriminant analysis. The contents of the three marker compounds (anisodamine, anisodine and atropine) in the roots and acrial parts of A. tanguticus were positive correlated and varied significantly from different geographical origins. Principal component analysis, and orthogonal partial least-squares discriminant analysis results showed excellent discrimination between different geographical origin of A. tanguticus. This study could provide comprehensive evaluation and further utilization of A. tanguticus resources.

Urban rivers play an important role in maintaining the urban aquatic ecological environment, and there are bound to be differences in the water environment quality and pollution sources due to different locations of urban rivers. Therefore, this paper selects the urban river (Tuo River) and the suburban river (Bian River) in Suzhou City, Anhui, China, as the research objects. Based on the understanding of the hydrogeochemical characteristics of these two rivers, the self-organizing map is used to identify the main control factors that affect the water quality of the two rivers. The results showed that both the Bian river and Tuo river were weakly alkaline. The average content of conventional ions in Tuo river is less than that of Bian river (except HCO3 −); the water of Bian river was of Na–SO4–Cl type, and the water of Tuo river was mainly of Na–HCO3 type, with the minority was of Na–SO4–Cl type; Silicate weathering is an important source of conventional ions in the water of these two rivers; agricultural non-point source pollution is the main source of pollutants in Bian river, while Tuo river was mainly affected by natural factors, and human activities had little impact.
