Application of manganese (II) phthalocyanine synthesized in situ in the SiO2/SnO2 mixed oxide matrix for determination of dissolved oxygen by electrochemical techniques
(Elsevier Science BvAmsterdamHolanda, 2011)
Evidence on Night Movements of Macroinvertebrates to Macrophytes in a Pampean Stream
(Scientific Research Publishing, 2014-07)
Nocturnal invertebrate abundance peaks in lotic systems are usually associated to drift, however, diel migrations other than drift may be important in slow-flowing systems. Then, macroinvertebrate distribution on macrophytes ...
Viabilidade da utilização do método delta aproximado para determinação do coeficiente de reaeração em rios
(Universidade Federal de Santa MariaBREngenharia AmbientalUFSMPrograma de Pós-Graduação em Engenharia Ambiental, 2016-03-28)
The dissolved oxygen is an important indicator that shows water quality variation in rivers, caused by the release/accumulation of organic matter. The determination of the reaeration coefficient is indispensable, due to ...
Degradação aeróbia e anaeróbia de lixiviados de macrófitas aquáticas em função da temperatura
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Ecologia e Recursos Naturais - PPGERNCâmpus São Carlos, 2021-10-18)
Aquatic macrophytes are extremely important organisms for the maintenance of aquatic ecosystems. Among the functions performed by aquatic plants is the cycling of carbon, nitrogen and phosphorus. These elements are released ...
A highly sensitive amperometric sensor for oxygen based on iron(II) tetrasulfonated phthalocyanine and iron(III) tetra-(N-methyl-pyridyl)-porphyrin multilayers
(Elsevier Science BvAmsterdamHolanda, 2008)
Systemic characterization of the oxygen response of the wine yeast saccharomyces cerevisiae EC1118 in oenological conditions.
(2013)
Discrete oxygen additions play a critical role in alcoholic fermentation. However, few studies have quantified the fate of the dissolved oxygen and its impact on wine yeast cell physiology, under oenological conditions. ...
