Métodos para predição de bitter pit em maçãs 'Fuji' e 'Braeburn'
(Universidade Federal de Santa Maria, 2009)
Experimentos foram conduzidos com objetivo de avaliar a eficiência de métodos para predição da ocorrência de bitter pit em maçãs 'Fuji' e 'Braeburn' em duas épocas de amostragem. Os frutos, provenientes de seis pomares ...
Corrosion behaviour of thermal sprayed nitinol coatings
(Pergamon-Elsevier B.V. Ltd, 2009-01-01)
NiTi alloy is here investigated as an alternative coating to stainless steel since it is considered to possess good corrosion properties. Three different thermal spray techniques (high velocity oxy-fuel -HVOF-, vacuum ...
Previsão de bitter pit em maçãs por meio da infiltração de Mg2+ e da aplicação de ethephon nos frutos
(Universidade Federal de Santa Maria, 2009)
Estudou-se o efeito da infiltração de magnésio e cálcio no desenvolvimento de sintomas de bitter pit de maçãs 'Gala'. Examinou-se, também, a eficiência da infiltração de magnésio e da aceleração da maturação de maçãs 'Royal ...

Stability analyses of footwall slopes in open pit mining
(Universidad Nacional de Colombia Sede Medellín, 2010)
In this paper we analyse different failure mechanisms typically associated to footwall slopes, in order to evaluate its stability using the numeric code UDEC. These results will then be analysed and contrasted against the ...
Optimizing Long-Term Production Plans in Underground and Open-Pit Copper Mines
(2012-02)
We present a methodology for long-term mine planning based on a general capacitated multicommodity network flow
formulation. It considers underground and open-pit ore deposits sharing multiple downstream processing plants ...
