Determination and persistence of methiocarb in artichokes
(1996-12-01)
A simple and rapid method for the determination of methiocarb in artichokes by high-performance liquid chromatography with UV detection is described. No derivatization is needed and the limit of determination (0.01 ppm) ...
Analysis of the Impact of PACE Programme on Access and Persistence in Higher Education in Chile
(2019)
Massification of higher education is a phenomenon that has been evidenced worldwide over the last decades. Chile has not been an exception. However, in a country with a highly segregated compulsory education system, the ...
Assessment of molecular and genetic evolution, antigenicity and virulence properties during the persistence of the infectious bronchitis virus in broiler breeders
(2017-10-01)
The infectious bronchitis virus (IBV) causes a highly contagious disease [infectious bronchitis (IB)] that results in substantial economic losses to the poultry industry worldwide. We conducted a molecular and phylogenetic ...
Effect of Aquatic Vegetation on the Persistence of Cypermethrin Toxicity in Water
(Springer, 2010-11)
Soybean production in Argentina comprises 15 million ha. Cypermethrin is the main insecticide applied amounting 150 g of active ingredient per hectare, thus representing roughly 2.3 thousand tons yearly released to the ...
Turbulence-induced persistence in laser beam wandering
(Optical Society Of America, 2015-07)
We have experimentally confirmed the presence of longmemory correlations in the wandering of a thin Gaussian laser beam over a screen after propagating through a turbulent medium. A laboratory-controlled experiment was ...
THE PERSISTENCE OF FIXED-RATIO AND DIFFERENTIAL-REINFORCEMENT-OF-LOW-RATE SCHEDULE PERFORMANCES
(Sociedad Mexicana de Análisis de la Conducta / Mexican Society of Behavior Analysis, 2015)
Effect of urbanization on the long-term persistence of streamflow records
(2015)
We investigate here the effect of urbanization on the temporal behavior of streamflow records. To this end, we analyzed daily streamflow records from 22 urban basins using the scaling exponents for long-term correlated ...
Milk yield persistency in Brazilian Gyr cattle based on a random regression model
(Funpec-editora, 2012-01-01)
With the objective of evaluating measures of milk yield persistency, 27,000 test-day milk yield records from 3362 first lactations of Brazilian Gyr cows that calved between 1990 and 2007 were analyzed with a random regression ...
