Effects of Energy Production and Consumption on Air Pollution in Serbia
Marija Živković (2019)Energy production and combustion, mostly from unregulated or inefficient fuel combustion, are the single most important anthropogenic sources of air pollutant emissions. Energy sector in Serbia is highly fossil fuel intensive: 87.88% of energy consumed in Serbia is related to fossil fuels, while almost 95% of energy sources are combusted. In 2017. energy related carbon dioxide emission in Serbia is was 47.95 million tones. The main source of carbon dioxide emission was coal, responsible for almost 70% of energy ...... electricity and heat generation, as well as from the transport and buildings sectors 6. The transport sector is a major source of air pollutants, despite the many policy and technology advances achieved so far.

Electronic Dictionaries - from File System to lemon Based Lexical Database
In this paper we discuss some well-known morphological descriptions used in various projects and applications (most notably MULTEXT-East and Unitex) and illustrate the encountered problems on Serbian. We have spotted four groups of problems: the lack of a value for an existing category, the lack of a category, the interdependence of values and categories lacking some description, and the lack of a support for some types of categories. At the same time, various descriptions often describe exactly the same ...... variants (for instance, istorija and historija ‘history’), full forms and their abbreviation (e.g. kilogram and kg), derivationally re- lated lexical entries (e.g. istorija and istorijski ‘relating to the study of history’), and different pronunciations (Eka- vian dete and Ijekavian dijete ‘child’). ...

Quantitative landslide risk assessment in the city of Tuzla
In the climate-changing conditions, geological environment interacts more dramatically with the urban fabric than before. The urbanization is expansive and more aggressive than before, but so are the weather extremes and long-term climate trends. In effect, many processes which can be triggered by either side, nature or engineering, are becoming more pervasive than before, and such is the case with landslides. Dealing and managing landslides requires few crucial steps, starting from collecting data on landslide location and typology – ...... remediation and prevention, fast emergency response, and other aspects of landslide risk management. 6 ACKNOWLDEGEMENTS This work was part of the Project “Detailed flood and landslide risk assessment for the urban areas of Tuzla and Doboj” funded by UNDP Office in Bosnia and Herzegovina and implemented ...
