Experimental and theoretical study on workpiece temperature when tapping hardened AISI H13 using different cooling systems
(Associação Brasileira de Engenharia e Ciências Mecânicas - ABCM, 2010)
Tapping operations on hardened steels have always been a great challenge. Dry machining and two cooling systems were used when tapping hardened AISI H13 (53 HRC). Embedded thermocouples were used for temperature measurement ...
Relevance of system size to the steady state properties of tapped granular systems

Comutador eletrônico de taps aplicado a um transformador de distribuição monofásico
(Universidade Federal de Santa MariaBREngenharia ElétricaUFSMPrograma de Pós-Graduação em Engenharia Elétrica, 2014-02-27)
Voltage regulation still is a problem faced by power utilities currently. In addition to the series
impedance and the significant load variation of the distribution grids, the main causes of voltage
regulation problems, ...
Surface characterization of copper, zinc and brass in contact with tap water inhibited with phosphate ions
(Elsevier Science, 2011-09)
The composition of the surface layers has been investigated on copper, zinc and brass in contact with moderately hard, highly carbonated and chloride rich artificial tap water (ATW). Cyclic voltammetry, reflectance ...

Agronomical performance and profitability of exploitation systems in four rubber tree clones in São Paulo state
(Instituto Agronômico de Campinas, 2010)
The exploitation or tapping of the rubber tree, Hevea brasiliensis (Willd. ex Adr. de Juss.) Muell. Arg. is one of the most important cultural practices in determining useful life, yield and accounts for a major part of ...
Analysis of IL1B, TAP1, TAP2 and IKBL polymorphisms on susceptibility to tuberculosis
Genetic determinants of human susceptibility to tuberculosis (TB) have not been completely elucidated. Interleukin-1 beta (IL-1?) and the inhibitor of kB-like (IkBL) are important molecules that participate in the inflammatory ...
