Dynamics of diuron and sulfentrazone formulations in soils with different textures
(2020-01-01)
Background: The use of commercial mix and tank mix with two or more herbicides is a widespread practice. However, despite its several possible benefits, little is known about its effect on the behavior of the molecules in ...
Stress concentration around perforations produced by corrosion in steel storage tanks
(Associação Brasileira de Engenharia e Ciências Mecânicas, 2014-06)
This paper presents numerical results of stress concentration factors for plates perforated by corrosion. Evidence from 25 plates with corrosion perforation considered show that typical shapes may be characterized as a ...
Conical Tank Level Control with Fractional PID
(IEEE-Inst Electrical Electronics Engineers, 2016)
A simulation study of fractional order PID (FOPID) applied to level control in a conic tank is presented in this paper. An improved mathematical model to represent better the nonlinear dynamic of the conic tank is derived ...
A portable electrochemical microcell for weld inspection of duplex stainless steel tanks
(2019-04-01)
Electrochemical tests are well-established techniques used in corrosion studies, with the development of microcells and microcapillaries enabling localized evaluation of specific microregions of a welded joint. Until now, ...
Pseudomonas spp.: Contamination sources in bulk tanks of dairy farms
(2017-09-01)
This study focused on isolating Pseudomonas spp. during milking process in ten dairy farms with manual and mechanical milking systems during dry and rainy seasons, and evaluating DNA homology and patterns of distribution ...
Passivation Level of AISI 316L Aseptic Tank Surface Quantified by On-Site Electrochemical Techniques
(2022-01-01)
Frequently stainless steel AISI 316L aseptic tanks have their passivity and corrosion resistance properties degraded by biofilm formation and localized corrosion processes. Thereby, maintenance projects are performed to ...
Molecular detection of Streptococcus agalactiae in bovine raw milk samples obtained directly from bulk tanks
(ELSEVIER SCI LTDOXFORD, 2012)
Mastitis is the most common infectious disease affecting dairy cattle; in addition, it remains the most economically important disease of dairy industries around the world. Streptococcus agalactiae, a contagious pathogen ...
Performance of single-drain and dual-drain tanks in terms of water velocity profile and solids flushing for in vivo digestibility studies in juvenile shrimp
(London, 2013-11)
In vivo digestibility determination in shrimp is a challenge because these animals are coprophagous, benthic and slow feeders and the small amount of feces that they produce is difficult to collect. The objective of this ...
