<p>Primenom tečne hromatografije na obrnutim fazama<br />ispitano je retenciono pona&scaron;anje 14 novosintetisanih<br />derivata s-triazina na tankom sloju RP C-18 i silika gelu<br />impregniranim parafinskim uljem. Kao pokretne faze<br />kori&scaron;ćene su dvokomponentne sme&scaron;e vode i organskih<br />rastvarača. Izračunate su R_M^0&nbsp;vrednosti i ispitana je<br />korelacija sa različitim deskriptorima i prediktorima<br />biolo&scaron;ke aktivnosti.</p> / <p>Retentional behaviour of 14newly syntetised derivates&nbsp;of s-triazine on RP C-18 and paraffin oil-impregnated&nbsp;silica gel suport had been investigated using thin-layer&nbsp;<br />chromatography. As a mobilephases were used two-component water based mobile &nbsp;phases. Calculated R_M^0&nbsp;values were corelated to various molecular descriptors&nbsp;<br />as well as biological activity indicators.</p>

<p>Osnovni cilj istraživanja je razvoj metodologije za okvirno vrednovanje uticaja<br />režima padavina na retencioni kapacitet sliva i upravljanje vodama. Formulisana<br />je originalna jednačine za indikator retencionog kapaciteta neizučenog sliva, u<br />funkciji kratkotrajnih jakih ki&scaron;a i prirodnih karakteristika čiji je uticaj na brzinu i<br />količinu oticaja sa sliva moguće nedvosmisleno kvantifikovati.Ovo je omogućilo<br />vrednovanje indikatora retencionog kapaciteta sliva, lociranje i procena uticaja<br />različitih mera na vrednost indikatora, kao i procenu uticaja predloženih mera na<br />sintetičke jedinične hidrograme. Praktičnost metodologije se ogleda u efikasnosti<br />sagledavanja uticaja predloženih mera, dono&scaron;enju odluka o njihovoj lokaciji na<br />slivu i primeni. Na ovaj način, dobijen je koristan alat za dobijanje informacija od<br />značaja za dono&scaron;enje odluka u sektoru voda i ostalim sektorima.</p> / <p>The main goal of this research is methodology development for assessment of the<br />rainfall impact on river basin retention capacity and water management. The original<br />equation is developed for the ungauged river basin retention capacity indicator in terms<br />of short-term heavy rainfall and natural features whose influence on the speed and the amount of surface runoff from the basin can be clearly quantified. This enabled the evaluation of the retention capacity indicator, location and evaluation of the effect of<br />different NWRM scenarios, as well as the assessment of the impact of the proposed<br />NWRM to synthetic unit hydrograph. Methodology convenience is reflected in the<br />efficiency of identifying the impact of the proposed measures, decisions on their<br />location in the basin and implementation. In this way, there has been a useful tool<br />obtained for providing the information relevant to decision-making in the water sector<br />and other sectors.</p>
