Effective method of treatment of effluents from production of bitumens under basic pH conditions using hydrodynamic cavitation aided by external oxidants
PublikacjaUtilization of cavitation in advanced oxidation processes (AOPs) is a promising trend in research on treatment of industrial effluents. The paper presents the results of investigations on the use of hydrodynamic cavitation aided by additional oxidation processes (O3/H2O2/Peroxone) to reduce the total pollution load in the effluent from the production of bitumens. A detailed analysis of changes in content of volatile organic compounds...

Versatile method employing basic techniques of genetic engineering to study the ability of low molecular weight compounds to bind covalently with DNA in cell free systems.
PublikacjaMechanizm działania większości leków przeciwnowotworowych oraz związków rakotwórczych polega na ich kowalencyjnym wiązaniu z DNA. Poziom tego wiązania jest zazwyczaj bardzo niski, co powoduje, że potrzebne są niezwykle czułe metody aby kowalencyjna modyfikacja mogła być w ogóle wykryta. My podjęliśmy próbę zastosowania w tym celu prostych, szybkich i sprawdzonych technik inżynierii genetycznej: metody PCR do uzyskania fragmentu...
