Synthesis and characterization of polyarylacetylene for use in the monolithic vitreous carbon processing
(Associação Brasileira de Polímeros, 2014-10-01)
In this work, polyarylacetylene (PAA) prepolymer obtained from 1,4-diethynylbenzene was evaluated as polymeric precursor of monolithic vitreous carbon (MVC). The monomer 1,4-diethynylbenzene was synthesized and the PAA ...

MICROBIAL OILS AND FATTY ACIDS: EFFECT OF CARBON SOURCE ON DOCOSAHEXAENOIC ACID (C22:6 N-3, DHA) PRODUCTION BY THRAUSTOCHYTRID STRAINS
(Chilean Society of Soil Science/Sociedad Chilena de la Ciencia del Suelo, 2010)
EFFECT OF CARBON:NITROGEN AND DISSOLVED OXYGEN ON THE BIOSURFACTANTS PRODUCTION FROM Bacillus subtilis
(2012-11-23)
The aim of the present study was to find the effect of the Carbon and Nitrogen (C:N) ratio and
dissolved oxygen (DO) concentration on biosurfactant production at flask and reactor level
respectively. The biosurfactants ...
Private valuation of carbon sequestration in forest plantations
(ELSEVIER SCIENCE BV, 2010)
Approval of the Clean Development Mechanism, provided for in the Kyoto Protocol, enables countries with afforested land to trade in carbon emissions reduction certificates related to carbon dioxide equivalent quantities ...
Remineralization of organic carbon in eastern Canadian continental margin sediments
(Deep-Sea Research Part II: Topical Studies in Oceanography, 2000)
Undisturbed sediment samples were collected for chemical analyses at six sites during winter and summer cruises to the eastern Canadian continental margin. Micro-electrode oxygen profiles were obtained in freshly collected ...
The heme oxygenase-carbon monoxide system in the regulation of cardiorespiratory function at high altitude
(2012)
Pulmonary arterial hypertension is one of the most serious pathologies that can affect the 140 million people living at altitudes over 2500. m. The primary emphasis of this review is pulmonary artery hypertension in mammals ...
Life cycle assessment and life cycle cost of sugar plants evaporators
(ESCOLA DE MINAS, 2010)
The evaporators of sugar plants in Brazil have used carbon steel intensively because of it is, a low priced material, which possesses inferior corrosion resistance. The materials more indicated for the substitution of ...
