RMA-11 is a numerical model widely used for studing the transport of constituents and water quality in rivers and estuaries. When applied to large water systems like the Rı́o de la Plata, RMA-11 demands long execution times to compute a simulation. This paper presents the analysis of the computational efficiency for the RMA-11 applied to a transport model of the Rı́o de la Plata, and introduces a...

In 1882, the director of the Córdoba Observatory became involved in a debate over international missions that were observing the transit of Venus across the sun, criticizing them for doing "harm to science, leaving substance aside in search of a shadow." The governor of Buenos Aires province and members of France's Bureau of Longitudes fostered these missions, and the instruments they used woul...

The Lens culinaris agglutinin-reactive fraction of AFP (AFP-L3) is widely used to screen for hepatocellular carcinoma (HCC) in Japan and China. We developed a chemiluminescent protein microarray for determining the AFP-L3/AFP index (the ratio of AFP-L3 to total AFP, AFP-L3%) by fixing AFP-specific antibodies and Lens culinaris lectin on aldehyde-coated glass slides. Serum samples were tested fo...

Third language (L3) acquisition differs from first language (L1) and second language (L2) acquisition. There are different views on whether L1 or L2 is of primary influence on L3 acquisition in terms of transfer. This study examines differences in the event-related brain potentials (ERP) response to agreement incongruencies between L1 Spanish speakers and L3 Spanish learners, comparing response...

AIM This study aimed to evaluate the fucosylated fraction of alpha-fetoprotein (AFP-L3) as a marker of early hepatocellular carcinoma (HCC). PATIENTS AND METHODS We diagnosed early HCC in 15 patients (15 tumors) by gadolinium-ethoxybenzyl-diethylenetriamine-pentaacetic acid-enhanced magnetic resonance imaging and confirmed the diagnoses using new criteria of the International Consensus Group ...

During 5,230 trapping nights, 672 small mammals were trapped in the areas where most hantavirus pulmonary syndrome (HPS) cases occur in Uruguay. Yellow pygmy rice rats (Oligoryzomys flavescens) were the only rodents that showed evidence of antibodies to hantavirus, with a seroprevalence of 2.6%. The rodents were trapped in all the explored environments, and most of the seropositive rodents were...

We study, through path-integral methods, an extension of the massive Thirring model in which the interaction between currents is nonlocal. By examining the mass-expansion of the partition function we show that this non-local massive Thirring model is equivalent to a certain non-local extension of the sine-Gordon theory. Thus, we establish a non-local generalization of the famous Coleman’s equiv...
