The largest glacier of the Petuniabukta area is the Hörbyebreen. It is among the tew on Spitsbergen whose marginal zones undergo areal decay. What has made in this type of glacier is a rich supra-glacial moraine cover that was formed as a result of a deformation of debris bands in the frontal part following a surge. In the marginal zone three subzones were distinguished differing in the degree of degradation of passive ice that covers almost all its area. They also differ in the stability of deposits and in the relief.
Notes about a handbook of Italian grammar by a Croatian philologist Dragutin Antun Parčić – A handbook of Italian grammar, written in Croatian by Croatian philologist Parčić, confirms that in the past educated Croatian-speaking people were bilingual and at the same time it proves that lower classes aimed to study Italian as well. The paper analyses the functionality and appropriateness of topics presented in the Parčić manuscript because it is obvious that the author was keen to help his Croatian-speaking students in the acquisition of Italian.
This paper presents the method of analysis of parametric systems in frequency domain. These systems are also referred to as linear time varying systems (LTV). The article includes a description of an analytical method for determining the frequency response of the first order parametric circuit with non-periodically variable parameters. The results have been illustrated by an example.
