Modelação da perda de carga na filtração direta ascendente em meio granular de areia grossa e pedregulho
(ABES, 2009)
Compreender e quantificar os mecanismos relacionados à perda de carga e à remoção de partículas em um meio filtrante granular é de importância fundamental para o estudo do processo da filtração. Este trabalho apresenta o ...
Loss of Y-chromosome does not correlate with age at onset of head and neck carcinoma: a case-control study
(Associação Brasileira de Divulgação Científica (ABRADIC), 2014)
Aferição dos valores dos comprimentos equivalentes utilizados na determinação da perda de carga localizada
(Universidade Federal do Pampa, 2017)
Improving the mathematical formulation for the detailed scheduling of refined products pipelines by accounting for flow rate dependent pumping costs
(Nara Medianeira Stefano, 2013-10)
This work presents a continuous-time mixed-integer linear programming (MILP) formulation to find the best detailed schedule for single-source multi-product pipelines, minimizing the total operating costs. By knowing the ...
Adjustment of the hazen-willians equation for determination of continuous pressure drop in PVC pipeAjuste da equação de hazen-willians para determinação da perda de carga contínua em tubulações de PVC
(2019-01-01)
The head loss is a fundamental parameter for the dimensioning of the pipes, being directly related to the cost of these pipes, the selection of the pumping system and the energy cost of electricity. That study fitted the ...
Classic and molecular cytogenetic analyses reveal chromosomal gains and losses correlated with survival in head and neck cancer patients
(American Association for Cancer Research (AACR), 2005-01-15)
Purpose: Genetic biomarkers of head and neck tumors could be useful for distinguishing among patients with similar clinical and histopathologic characteristics but having differential probabilities of survival. The purpose ...
