Xanthine Oxidase Inhibitory Properties of 1,2,3,4–Tetrahydroisoquinoline Derivatives / Inhibicija ksantin oksidaze derivatima 1,2,3,4-tetrahidroizohinolina
(Acta Medica Medianae, 2021)
Xanthine oxidase (XO) is a versatile metalloflavoprotein enzyme that is best known for its rate-limiting role in the purine degradation pathway. Therapeutic inhibition of XO is based on its role in a variety of diseases ...
Revitalization of rotational biological contactors / Revitalizacija rada 'Bio-disk' uređaja
(Udruženje za tehnologiju vode i sanitarno inžinjerstvo, Beograd, 2009)
Treatment of waste water in rotating biological contactors (RBC) requires knowing technical and technological conditions and understanding of microbiological processes. Deficient knowledge of these processes and operating ...
X-rаy diffraction and SEM analysis of waste sulfur modification for use in concretes
(University of Belgrade - Faculty of Mining and Geology, 2021)
Secondary sulfur obtained as a by-product in the oil refining process is a major problem as an environmental pollutant. One of the possibilities for environmental protection is the use of sulfur obtained in this way as a ...
Cavitation of refratory samples based on talc and domestic zeolite / Ispitivanje vatrostalnih uzoraka na bazi talka i domaćeg zeolita na dejstvo kavitacije
