The Río de la Plata, one of the most important South American estuarine environments, is characterized by a bottom salinity front that generates an ecotone between the river and the estuary. Based on bottom trawls and costal sampling we describe the distribution, types, and amount of debris found in the bottom and shoreline across this front. Plastics and(More)
Choked lagoons (like Mar Chiquita, Argentina) are influenced by local winds because the inlet channel acts as a dynamic filter which reduce tidal fluctuations. Previous studies showed that the effects of onshore winds appear to prevail over daily-tide cycles (ebb, flood) in the recruitment of young fishes into this micro-tidal and shallow estuary.(More)
Almost all DNS queries that traverse Internet are transported via UDP in self-contained small packages. Therefore, with no restriction of packet ordering, the intuition would say that adding thread-based parallelism to the servers will increase their performance, but it does not. This paper studies the problem of serialized access to UDP sockets, and states(More)
The aim of this study was to assess seasonal and spatial variations in fish larvae abundance between areas with Macrocystis pyrifera kelp forests and areas without them off the coast of the Beagle Channel. Monthly plankton sampling at three sites was performed from June 2014 to May 2016 in two areas of each site. One area was defined along the offshore(More)
The aim of this study was to analyze the organic matter (OM) origin in the nearshore and the surf zones adjacent to Mar Chiquita lagoon, in order to determine the importance of allochthonous estuarine detritus and in situ marine phytoplankton as carbon (C) sources for young fishes prior to entering the lagoon. Water samples from both the nearshore and the(More)
Ingestion of anthropogenic debris represents an important threat to marine turtle populations. Information has been limited to inventories of debris ingested and its consequences, but why ingestion occurs and the conditions that enable it are less understood. Here we report on the occurrence of plastic ingestion in young green turtles (Chelonia mydas)(More)
The focus of this paper is to report key aspects of the laboratory-level performance on a three-phase, scaled-down thyristor controlled series capacitor, TCSC, prototype. All-important issues concerned to the design and construction of the prototype are included in this work. The testing of the TCSC prototype is restricted to steady-state conditions.(More)
