An overview of the microstructures present in high-speed steel - Carbides crystallography
(2006-12-01)
The aim of the work was to prepare an overview about the microstructures present in high-speed steel, focused on the crystallography of the carbides. High-speed steels are currently obtained by casting, powder metallurgy ...
The effect of TiO2 nanotube morphological engineering and ZnS quantum dots on the water splitting reaction: A theoretical and experimental study
(2018-04-05)
Ordered arrays of TiO2 nanotubes with smooth and rippled morphologies were prepared by one-step titanium oxidation in NH4F and ethylene glycol solution. The samples were then decorated with ZnS using a microwave-assisted ...
A refined FSDT for the static analysis of functionally graded sandwich plates
(Elsevier, 2015-05)
This paper presents a static analysis of functionally graded plates (FGPs) by using a new first shear deformation theory (FSDT). This theory contains only four unknowns, with is even less than the classical FSDT. In this ...
Provenance as a knowledge organization principlet
(2019-01-01)
The principle of provenance is one of the most important milestones in archival practice and theory from the time its establishment grounded the scientific dimension of archival discipline in the nineteenth century. Since ...
O princípio da precaução e sua aplicação diante de riscos catastróficos
(Universidade do Vale do Rio dos Sinos, 2016-12-21)
The present paper studies the application of the Precautionary Principle in the face of the catastrophic risks. Environmental disasters have potential impact and complexity, which is why Brazil has developed a branch of ...

Electronic Structure, Morphological Aspects, Optical and Electrochemical Properties of RuO2 Nanocrystals
(Korean Inst Metals Materials, 2019-09-01)
This letter reports the synthesis of RuO2 nanocrystals by the anionic surfactant-assisted hydrothermal method at 90 degrees C for 24 h followed by heat treatment at 500 degrees C for 1 h. These crystals were structurally ...
Protocol to refine intestinal motility test in mice
(2004-07-01)
We propose a new protocol intended to conform to the 3Rs (replacement, reduction, and refinement) principle, using animals fasted for 3 h to control intestinal motility, which reduced stress in the animals. In this new ...
A new method for assessing compatibility of consolodation procedures with conservation principles: Intervention Qualitiy Index
In current times, built heritage is being lost at an alarming rate due to natural and human hazards. Policies for its protection and rehabilitation involve, among other things, challenges related to the refinement of ...
