Autochthonous dissolved organic matter potentially fuels methane ebullition from experimental lakes
(Pergamon-Elsevier Science Ltd, 2019-12-01)
Shallow lakes are hotspots for carbon processing and important natural sources of methane (CH4)emission. Ebullitive CH4 flux may constitute the overwhelming majority of total CH4 flux, but theepisodic nature of ebullition ...
Palavras em desdobramento na poesia de Herberto Helder
(2010)
No poema Em silêncio descobri essa cidade no mapa, inserido em A máquina lírica (1964), Herberto Helder desenha um contra mapa desnorteante com as palavras, que pulalam na travessia da escrita, deslocando-se incessantemente ...
Usable work of macro-scale cavities in liquids
(Associação Brasileira de Engenharia e Ciências Mecânicas - ABCM, 2012)
It is shown that the generation of cavities in a liquid can produce usable work, which is illustrated by the stretching of a string. This work is done during the expansion of the cavity, and not with its collapse. Basic ...
