Influence of the chemical structure of poly(urea-urethane-siloxane)s on their morphological, surface and thermal properties
(Springer Verlag, 2013)
Segmented poly(urethane-urea-siloxane)s (PUUS) were synthesized using 4,4'-methylenediphenyl diisocyanate (MDI) and ethylene diamine (ED) as the hard segment components and hydroxypropyl-terminated poly(dimethylsiloxane) ...
The effect of meteorological and chemical parameters on summer phytoplankton assemblages in an urban recreational lake
(EDP Sciences, 2017)
The summer phytoplankton community was studied across both vertical and temporal scales in relation to environmental factors in the shallowrecreational Sava Lake. The sampling was conducted weekly at four depths from ...
Assessment of the pseudo total metal content in alluvial sediments from Danube River, Serbia
(Springer, New York, 2011)
We used elemental carbon, nitrogen, hydrogen and sulfur as well as ratios of hydrogen and nitrogen with total organic carbon for investigation of source and conditions of organic matter in alluvial Danube sediments. We ...
