Alkaline sulfite/anthraquinone pretreatment followed by disk refining of Pinus radiata and Pinus caribaea wood chips for biochemical ethanol production
(WILEY-BLACKWELLMALDEN, 2012)
BACKGROUND: Alkaline sulfite/anthraquinone (ASA) cooking of Pinus radiata and Pinus caribaea wood chips followed by disk refining was used as a pretreatment for the production of low lignified and high fibrillated pulps. ...

Enzymatic Hydrolysis of Chemithermomechanically Pretreated Sugarcane Bagasse and Samples with Reduced Initial Lignin Content
(WILEY-BLACKWELL, 2011)
Chemithermomechanical (CTM) processing was used to pretreat sugarcane bagasse with the aim of increasing cell wall accessibility to hydrolytic enzymes. Yields of the pretreated samples were in the range of 75-94%. Disk ...

The present paper approaches the case study in the WestRock Pulp and Paper Factory, more specifically the process of preparing the cellulosic pulp, so that the paper to be produced can be formed, making sure the quality ...
The dust disk and companion of the nearby AGB star L-2 Puppis SPHERE/ZIMPOL polarimetric imaging at visible wavelengths
(ESO, 2015)
The bright southern star L-2 Pup is a particularly prominent asymptotic giant branch (AGB) star, located at a distance of only 64 pc. We report new adaptive optics observations of L2 Pup at visible wavelengths with the ...
Unveiling the role of galactic rotation on star formation
(The American Astronomical Society, 2016-11-10)
We study the star formation process at galactic scales and the role of rotation through numerical simulations of spiral and starburst galaxies using the adaptive mesh refinement code Enzo. We focus on the study of three ...
Influence of Cryogenic Treatments on the Wear Behavior of AISI 420 Martensitic Stainless Steel
(Springer, 2017-11)
The objective of the present work is to characterize the wear behavior of a cryogenically treated low-carbon AISI 420 martensitic stainless steel, by means of ball-on-disk tribological tests. Wear tests were performed under ...
