The present geodetic reference frame in Latin America and the Caribbean is given by a network of about 400 continuously operating GNSS stations. These stations are routinely processed by ten Analysis Centres following the guidelines and standards set up by the International Earth Rotation and Reference Systems Service (IERS) and International GNSS Service (IGS). The Analysis Centres estimate daily and weekly station positions and station zenith tropospheric path delays (ZTD) with an hourly sampling rate. This contribution presents some attempts aiming at combining the individual ZTD ...

In Mendoza, Argentina, quinoa is grown with a very good yield, and its consumption is becoming widespread. It is consumed as a seed, flour, expanded, sprout (germinated) and activated (hydrated). The popular belief is that all these forms have the same nutritional contribution. Taking into account this belief, the objective of this work was to determine the nutritional composition of the different preparations. The same batch of quinoa seeds was processed as flour, expanded, hydrated and sprout. It was analyzed by triplicate, applying conventional laboratory techniques. For the statistical ...

Vector borne diseases are spreading worldwide. Companion animals can be useful as sentinels for disease surveillance. Setaria spp. are filarial nematodes transmitted by Aedes spp. and Culex spp. Setaria equina has been reported in Asia, Africa and North America. This zoonotic nematode is frequently asymptomatic in horses, except during its erratic migrations. Filarial worms have a tropism for ocular and nervous tissues, having important implications in veterinary and public health. In mid west Argentina, Dirofilaria immitis has already been described affecting a woman and dogs. There are no ...
