Life Cycle Assessment Of Poly(lactic Acid) (pla): Comparison Between Chemical Recycling, Mechanical Recycling And Composting
(Springer/Plenum PublishersNew York, 2016)
Oxidative stress, cell cycle arrest and differentiation contribute toward the antiproliferative action of BSO and calcitriol on Caco-2 cells
(Lippincott Williams, 2014-08)
The prognosis and incidence of colon cancer are linked to vitamin D3 serum levels. To evaluate the effects of D,L-buthionine-S,R-sulfoximine (BSO), 1,25(OH)2D3 and their combination on intestinal Caco-2 cell growth, to ...
The effects of mechanical and hydrothermal aging on microstructure and biaxial flexural strength of an anterior and a posterior monolithic zirconia
Objectives To evaluate the effect of hydrothermal aging (H), mechanical cycling (M), and the combination of hydrothermal plus mechanical cycling (H + M) on biaxial flexural strength (BFS) and microstructure of two monolithic ...
Review on produccion processes and mechanical properties of dual phase austempered ductile iron
(American Foundry Society, 2012-01)
During the last few years, researchers have sought new ductile iron (DI) applications focusing on the development of mixed microstructures, such as ferritic-bainitic or ferritic-martensitic. These kinds of structures result ...
The Combination of Vitamin K-3 and Vitamin C Has Synergic Activity against Forms of Trypanosoma cruzi through a Redox Imbalance Process
(Public Library Science, 2015-12-07)
Chagas' disease is an infection that is caused by the protozoan Trypanosoma cruzi, affecting millions of people worldwide. Because of severe side effects and variable efficacy, the current treatments for Chagas' disease ...
análise dos efeitos ionosféricos de ordem superior no ciclo solar 24 e influência no posicionamento GNSS absoluto
(Universidade Federal do Paraná, 2014-12-01)
The application of the ionosphere free combination for GNSS dual frequency data allows mathematically the elimination of the first order ionosphere effects. However, the higher order ionosphere effects are not eliminated ...
Multivariate analysis of the energy cycle of the South American rainy season
(JOHN WILEY & SONS LTD, 2009)
The South American (SA) rainy season is studied in this paper through the application of a multivariate Empirical Orthogonal Function (EOF) analysis to a SA gridded precipitation analysis and to the components of Lorenz ...
Life cycle assessment of fuel ethanol from sugarcane in Argentina
(Springer Heidelberg, 2013-08)
Purpose The production of bioethanol in Argentina is based on the sugarcane plantation system, with extensive use of agricultural land, scarce use of fertilizers, pesticides, and artificial irrigation, and burning of ...
Generalized hopf bifurcation in a frequency domain formulation
(World Scientific, 2012-08)
The multiplicity problem of limit cycles arising from a weak focus is addressed. The proposed methodology is a combination of the frequency domain method to handle some degenerate Hopf bifurcations with the powerful tools ...
