CLIMATIC CONDITIONS IN THE MARINE PARK OF SILBA
As part of the project Preservation of biological diversity in the Adriatic sea the climatic conditions and climatic variability in the marine park Silba in the period 1964-1993 have been analysed. As amount of precipitation, evaporation and soil moisture greatly affect
the island flora, the mean annual values of water balance components (potential and actual evapotranspiration and moisture loss from the soil) have been calculated by the Palmer method.
According to linear trend analyses and the nonparametric Mann-Kendall test, the existence of a significant trend of potential evapotranspiration (decreasing chronology) and relative air humidity
(increasing chronology) has been established during the last 30 years. A tendency towards decrease in precipitation amount and actual evapotranspiration has also been observed, but the linear trends are not significant at the 0.05 level. Significant linear trends in air temperature and soil moisture loss do not occur
THE PHENOLOGICAL FLUCTUATIONS AS A POSSIBLE SIGNAL OF CLIMATIC CHANGES
The development (phenological) stages of some perennial plants and herbaceous plants as well stages of field work operation have been analysed at the mountain station GospiÄ during the available periods (mainly 1954ā2004). The results of the linear trend analysis indicate a significant earlier blooming for plants which bloom in the second half of April and May. Those variations are the consequence of a significant increase in winter and spring insolation and air temperature

TEMPERATURE SUMS AND CLIMATIC VARIATIONS IN THE PARG REGION
Time series of temperature sums for the different temperature thresholds from the Parg station in the Croatia mountain area during the vegetation period from 1951 to 2004 have been analysed. The temperature differences between mean temperatures and temperatures thresholds are called the temperature sums or degree days and they are frequently applied in agrometeorology. The results of linear trend analysis and the Mann-Kendall test are
shown that the significant linear trends temperature sums exit above thresholds 15Ā°C and 20Ā°C (increasing by time) which are the consequence of significant increase in mean maximum temperature in spring and summer
IVAN POTOÄNJAK FIZIÄAR I METEOROLOG
U radu se govori o prof. Ivanu PotoÄnjaku koji je zaslužan za prvi udžbenik iz meteorologije. Njegov rad na Gospodarskom Å”umarskom uÄiliÅ”tu u Križevcima zapoÄinje 1875. gdje Äe godinama održavati nastavu meteorologije i klimatologije te rukovoditi radom meteoroloÅ”ke postaje. Prvi meteoroloÅ”ki udžbenik na hrvatskom jeziku objelodanio je 1878. Osim ovoga udžbenika tiskao je sam ili u koautorstvu i druge udžbenike za koje se malo zna, a kako su iz
razliÄitih podruÄja znanosti nisu se ukupno dovodili u vezu s prof. Ivanom PotoÄnjakom
Geothermal and mineral waters of Croatia
U ovom seminaru pokuÅ”ala sam Å”to jednostavnije prikazati bogatstvo mineralnim i geotermalnim vodama na prostoru Hrvatske. Ukratko, termalne i mineralne vode vezane su uz odreÄene tektonske i litostratigrafske uvjete koji moraju postojati da bi one izbile na povrÅ”inu ili da bi se naÅ”le u podzemlju. Å to se tiÄe kemijskog sastava neke su geotermalne vode slabo,a neke jeÄe mineralizirane. S obzirom na to one se mogu koristiti kao tehniÄka, sanitarna, voda za piÄe ili voda s balneoloÅ”kim svojstvima. Mineralna voda se kod nas koristi za lijeÄenje, rekreaciju, u zdravstvenom turizmu te ponegdje za punjenje boca s vodom za piÄe. Za racionalno gospodarenje geotermalnim i mineralnim vodama u Hrvatskoj potrebno je osigurati jedinstven sustav gospodarenja, nadzora koriÅ”tenja i zaÅ”tite tih voda.In this seminar I tried to show simply as posible the wealth of Croatia with mineral and geothermal waters. In few words, thermal and mineral waters are related to a specific tectonic and lithostratigraphic conditions that have to exist in order for water to emerge or to be found in underground. As regards the chemical composition some of the geothermal waters are poorly, and some are more mineralized. According to this, one can be used as technical, sanitary, water for drinking or water with balneological use. We use mineral water for treatment, recreation, medical tourism and somewhere for bottling drinking water. For rational management of geothermal and mineral waters in Croatia it is necessary to ensure a unifide system of management, supervision and protection of water
THE IMPORTANCE OF USING ICT IN THE RURAL TOURISM OF THE ZADAR COUNTY
Rural tourism, as a new way of tourism evolved from the combination of ecotourism and agro-tourism, has been considered as good way of economic and social revitalization in the world. We can say that ICTs are necessary components of doing business in rural tourism. This article shows the usage of basic ICTs in rural tourism of the Zadar County. It is therefore necessary to encourage stronger collaboration between all relevant institutions in order to implement ICT in rural tourism which can make Croatian tourism much more competitive. The aim of this article was to determine importance of ICTs in the future of rural tourism development in Zadar County
The impact of a hydroelectric power station on the development and modernization of the Bajina BaŔta settlement during the socialist period
During the process of socialist modernization, initiated after WWII, large development projects in Serbia were the main drivers of urban transformation. Electrification and industrialization resulted in the establishment of new production modes, which defined a new socio-economic background for the development of settlements and the modification of their functional and morphological structure. The construction of the Bajina BaŔta hydroelectric power station, in the middle section of the Drina River in western Serbia, was one of the development projects, and it triggered the transformation of the environment, upgrading the pre-war small town of Bajina BaŔta into a new urban node, adjusted to the socialist imperatives and standards of progress
