Bakalauro baigiamajame darbe nagrinėjama AB Šiaulių banko finansinė veikla. Pateikiama šiuolaikinė bankų sistemos struktūra. Taip pat apžvelgiama komercinio banko veikla, bei jos riziką ribojantys normatyvai. Įvertinta AB Šiaulių banko finansinė padėtis tarp kitų šalies komercinių bankų. Išnagrinėjus teorinius finansinės veiklos analizės metodus atliktos banko balanso, pelno (nuostolio) horizontalioji ir vertikalioji analizės. Apskaičiuoti pagrindiniai AB Šiaulių banko finansiniai santykiniai rodikliai, įvertinantys banko pelningumą, veiklos efektyvumą, likvidumo ir kapitalo riziką. Įvertinti finansiniai santykiniai rodikliai parodo banko būklę bei perspektyvas, todėl galima ieškoti būdų sumažinti ar net laiku pašalinti bankroto grėsmę. AB Šiaulių banko bankroto rizika įvertina naudojant E. Kaciak bei E. Eygi Erdogan bankroto tikimybės modelius. / In the present Bachelor’s Thesis, there are analysed the financial activities of the AB Šiaulių bankas. The modern system of bank is presented. Furthermore, there are revised the activities, risks and risk limiting standards of the commercial bank. The financial condition of the AB Šiaulių bankas between other commercial banks of the country is reviewed. Having analysed the theoretical methods of the analysis of financial activities, the horizontal and vertical analyses of the balance, profit (loss) of the bank were performed. The main financial rates and indicators of the AB AB Šiaulių bankas assessing the profitability, performance efficiency, liquidity and capital risks were calculated. The assessed financial relative rates and indicator demonstrate the state of the bank and the perspectives thereof, therefore it is possible to seek for method to minimise or even to eliminate timely the threat of bankruptcy. The bankruptcy risk of the AB Šiaulių bankas was assessed using E. Kaciak and E. Eygi Erdogan’s bankruptcy probability models.

Biogenic volatile organic compounds (VOCs) react with Cl and OH radicals and the resulting radicals combine with oxygen to form peroxy radicals RO2. Organic peroxy radicals can then react with NO to form NO2, a precursor of tropospheric ozone. The work presented here explored the initial reaction between Cl and thujone, a VOC emitted by Great Basin sagebrush. The rate constant for the reaction of thujone + Cl at 296 K was measured with the method of relative rates with FTIR for detection of reactants. LEDs were used to photolyze Cl2 to generate Cl in the reaction cell. Thujone was also photolyzed by the LEDs and therefore the relative rates model was revised to account for this photolysis. With toluene as the reference compound, the rate constant for thujone + Cl at 296 K is 2.62 ± 1.90 × 10-12 molecules-1 s-1, giving an atmospheric lifetime of 0.5--2.6 minutes for thujone. Cline et al. showed that the rate of the self-reaction of HO2CH2CH2O2 (β-HEP) increases in the presence of water vapor. This enhancement has a strong temperature dependence with a greater enhancement observed at colder temperatures. The observed rate enhancement has been attributed to the formation of a β-HEP--H2O complex. In this work, the equilibrium constant for the formation of the β-HEP--H2O complex was calculated by ab initio calculations. Given the energy available at room temperature, the complex will populate three local minimum geometries and β-HEP will populate two local minimum geometries. The partition function for each of these geometries was calculated and used to calculate the equilibrium constant for complex formation as a function of temperature. Based on these computational results, the observed temperature dependence for the rate enhancement can be attributed to the strong temperature dependence for the rate constant of the reaction of β-HEP--H2O + β-HEP rather than the temperature dependence of complex formation.
