Based on the monitoring data, features of long-term changes evaporation from water surface are determined. Data relatively small evaporators and basins located in different regions Ukraine were processed. It was found that during first part observation period, which began 1950s, had tendency to decrease, while second it increased significantly. To determine factors these changes, existin...

data envelopment analysis (dea) is a mathematical technique to evaluate the performance of firms with multiple inputs and outputs. in conventional dea models, the efficiency scores of decision making units (dmus) with non-negative inputs and outputs are evaluated in a special period of time. however, in the real world there are situations wherein performance of firms must be evaluated in multip...

This paper details a new method of regression for sparsely sampled data sets for use with time-series analysis, in particular the Stratospheric Aerosol and Gas Experiment (SAGE) II ozone data set. Non-uniform spatial, temporal, and diurnal sampling present in the data set result in biased values for the long-term trend if not accounted for. This new method is performed close to the native resol...

in order to identify the best maturity time for excision of fertilized ovules in interspecific hybridization, intercrosses were made between two diploid (gossypium herbaceum and g. arboreum, 2n=26) and two tetraploid species (g. barbadense and g. hirsutum, 2n=52). flower morphology, growth rate of ovules and ovaries, as well as fiber growth pattern in various time scales post anthesis were reco...

Lake area, water level, and storage changes of terminal lakes are vital for regional resource management understanding local hydrological processes. Nevertheless, due to the complex geographical conditions, it is difficult investigate analyze this change in ungauged regions. This study focuses on ungauged, semi-arid Gahai Lake, a typical small lake Qaidam Basin. In addition scant observed data,...

In the last decade several mining areas and corresponding dumps are subject to reclamation process in Bulgaria. We focused our research on one of the most important in the copper production for 20 year period for our country – Medet deposit. This mining complex consists of an open cast mine, the overburden dumps and a processing plant. After ceasing its exploitation in 1994 a rehabilitation pro...
