Síntese de caracterização de nanolubrificante de Licuri de gado
(BrasilUFRNPROGRAMA DE PÓS-GRADUAÇÃO EM ENGENHARIA MECÂNICA, 2018-01-26)
Vegetable oils are the alternative for the production of biodegradable and nontoxic
lubricants, but the high oxidative rate is a complicating factor. Therefore, this
work proposes the use of transesterified Licuri Gado ...
Resistência à fadiga e comportamento em torção de instrumentos endodônticos de NiTi Profile
(Universidade Federal de Minas GeraisUFMG, 2004-01-30)
A comparative study of the torsion behavior and of the fatigue resistance of rotary NiTi endodontic instruments was performed in this work. ProFile 20/.04, 25/.04, 30/.04, 20/.06, 25/.06 e 30/.06 instruments were analyzed ...
Control de flujo de acero líquido en el distribuidor mediante el diseño de la buza de la olla
(2018-05-03)
RESUMEN: La colada continua es un proceso siderúrgico en el que el acero líquido se vierte directamente en un molde de fondo abierto cuya sección transversal tiene la forma geométrica del semi producto que se desea ...
Integrating energy and land-use planning: Socio-metabolic profiles along the rural-urban continuum in Catalonia (Spain)
Abandoning fossil fuels and increasingly relying on low-density, land-intensive renewable energy will increase demand for land, affecting current global and regional rural–urban relationships. Over the past two decades, ...

Transient Solution for the Energy Balance in Porous Media Considering Viscous Dissipation and Expansion/Compression Effects Using Integral Transforms
(Springer VerlagBrasilNúcleo Interdisciplinar de Dinâmica dos Fluidos, 2019)
Characterization of the convective boundary layer through a combination of large-eddy simulations and a radar simulator
(University of Oklahoma, 2011)
The boundary layer (BL) is the lowest part of the atmosphere where the flow field is directly influenced by interactions among air, heat, and the Earths surface. The structure of flow in the BL is dynamic due to the fact ...
