Abstract:
Negotin Krajina geographically belongs to Mezian tablet that means it is widely open to the influences from the East but main air influences come from the West and North-West causes specific thermal characteristics. Meteorological station "Negotin" is the only one respectable station in the Krajina then we analyze results from various periods since 1901. It is important to emphasize that station "Negotin" doesn't have work continuity since the beginning of the century, thus for analyzing certain climate elements we have had to use method of analogy with station "Zajecar". A part of that, observations were not done by the same methodology so there is lack of some important indicators for this first period. To determine air thermo-regime of Negotin Krajina during 20 century, standard periods (1901-1930., 1931-1960. and 1961-1990) for analyzing climate elements suggested by WMO, were compared. Also, periods from 1925. to 1940. and from 1990. to 2000. were added to this analysis (according to data we had).

Abstract:
Sublethal effects of a pymetrozine-based product (commercial product Chess 50 WP) on life history traits and population growth of one commercialized strain (?Dutch? strain) and two local populations (Bujanovac and Negotin) of the whitefly parasitoid Encarsia formosa Gahan (Hymenoptera: Aphelinidae) were evaluated in laboratory bioassays. All trials were carried out at 27?1?C temperature and under 60?10 % relative humidity and 16/8 h daylight/darkness photoperiod in four replications. Longevity of wasps exposed for 48 h to residues of the pymetrozine insecticide (LC50, 280 mg a.i./l) was shorter (by 2.7-3 days) than that of control wasps. Total parasitism of Negotin wasps was significantly reduced (by 8.2 %), as well as total parasitism and adult emergence of the Dutch strain (by 7.3 and 8.2 %, respectively), compared to control wasps. The instantaneous rate of increase (ri) of surviving adult wasps was also significantly reduced (by 6.6, 6.3 and 7.6 % in populations Negotin, Bujanovac and Dutch strain, respectively). Direct treatment of wasps at their pupal stage (LC50, 300 mg a.i./l) reduced total parasitism of Negotin wasps (by 8 %), and reduced ri levels, but the reduction was significant only for the Bujanovac (by 6.7 %) and Negotin (by 4.6 %) populations. Juvenile development of the parasitoid in treated pupae was significantly extended (by 0.3-1.1 days), compared to control wasps. The implications of these results on integrated control of the greenhouse whitefly are discussed.

Abstract:
Climatology is traditionally connected to different conditions of the atmosphere. However, many occurrences appear from time to time. Those occurrences are defined as extreme. Nowadays it is important to study extreme occurrences for every geographical area. In this paper we have investigated one segment of extreme climatic conditions in Eastern part of Serbia - adverse characteristics of precipitation. Data for Negotin were analyzed, as a representative of the climate in this area. Extreme values of precipitation in one place were taken as dangerous occurrences. We have calculated thresholds above which we consider daily amount of precipitation as dangerous. Thresholds for dangerous lengths of rainy and droughty periods were calculated, too.

Abstract:
According to its physical-geographical and socio-economical characteristics, the municipality of Negotin belongs to the territories with favorable tourist potentials. In order to scientifically validate this fact, in this paper tourist valorization has been performed using quantitative-qualitative method, giving attractiveness ranking values, based on which conclusions have been made on the direction and forms of tourist potential. The results obtained from tourist valorization have shown that the hydrographic potential and fauna are rated as good (3), and have the highest general tourist value among natural resources. General values are graded as satisfactory (1.8) and the climate is graded as unsatisfactory (1.2). Valorization of anthropogenic characteristics gave the maximal general value (4) to cultural-historical objects including sacral objects - monasteries and churches and the Rajac pimnice. The Rajac pimnice have an especially high value, as they represent, for us, a unique value that can be considered in diverse ways and adjusted to tourist utilization. Based on the performed tourist valorization it can be noted that the general tourist value of the municipality of Negotin is of regional ranking, though anthropogenic potentials are of national ranking and part of them, as emphasized, are objects that are internationally important. The basic shortcoming is the low road quality leading to places of important tourist value, even though the road network is favorable, and there are also many weaknesses in the receptive tourist base. Improvement of these shortcomings would create a good image of the municipality of Negotin in continental tourism of the Republic of Serbia.

Abstract:
The analysis of demographic factors of the studied area points to the different demographic development models. Uneven economic and regional development of industry caused the regional demographic polarization of the population of Negotin municipality. In relatively short period, the transition has caused spontaneous urbanization and deagrarization. All that influenced the faster tempo of social and demographic processes, especially the migrations towards Negotin, which led to the developmental unevenness and regional polarization to the zone of population concentration (town and the suburban areas). Contrary to the town center, there are depopulation rural areas, with outstanding economic undevelopment.

Abstract:
In this paper basic information of Homer software for PV system electricity generation, NASA - Surface meteorology and solar energy database, RETScreen, PVGIS and HMIRS (Hydrometeorological Institute of Republic of Serbia) solar databases are given. The comparison of the monthly average values for daily solar radiation per square meter received by the horizontal surface taken from NASA, RETScreen, PVGIS and HMIRS solar databases for three locations in Serbia (Belgrade, Negotin and Zlatibor) is given. It was found that the annual average values of daily solar radiation taken from RETScreen solar database are the closest to the annual average values of daily solar radiation taken from HMIRS solar database for Belgrade, Negotin and Zlatibor. Monthly and total for year values of electricity production of fixed on-grid PV system of 1 kW with optimal inclinated and south oriented solar modules, in Belgrade, Negotin and Zlatibor using HOMER software simulation based on data for daily solar radiation taken from NASA, RETScreen, PVGIS and HMIRS databases are calculated. The relative deviation of electricity production of fixed on-grid PV system of 1 kW using HOMER software simulation based on data for daily solar radiation taken from NASA, RETScreen, and PVGIS databases compared to electricity production of fixed on-grid PV system of 1 kW using HOMER software simulation based on data for daily solar radiation taken from HMIRS databases in Belgrade, Negotin and Zlatibor are given.

Abstract:
Demographic projections represent a multi-purpose instrument in predicting the population development for the purpose of spatial planning and organizing as well as local economic development. In Serbia, demographic projections are very rarely produced on territorial levels lower than regional, therefore, the projections that are depicted in this work will be focused on the municipality of Negotin with the goal of observing an exceptionally depopulated area located in Eastern Serbia. The projections have been created with a time horizon of the year 2040 by using the cohort-component method which is well-established in literature as a prevailing method of producing population projections. Population projections for the municipality of Negotin have been constructed in three variants all relying on the initial hypotheses of fertility, mortality, and migrations. This is also the first time that such projections have been made separately for a rural and urban area of the municipality of Negotin. Results have shown that by the year 2040, the population will range between 17 and 18 thousand citizens, with the depopulation rate in rural areas being twice as high as that of urban ones. With the current demographic state in mind, it is evident that only direct interventions in the domain of migrational policies could slow down the pace of depopulation. This is due to the fact that the current fertility potential is undoubtedly insufficient to slow down depopulation even in the occurrence of a complete response to pronatalist policies.
