Plastics have been found in several compartments in Antarctica. However, there is currently no evidence of their presence on Antarctic glaciers. Our pilot study investigated plastic occurrence on two ice surfaces (one area around Uruguay Lake and ano

Characterizing the cyclic magnetic activity of stars that are close approximations of our Sun offers our best hope for understanding our Sun’s current and past magnetism, the space weather around solar-type stars, and more generally, the dynamos of

Climate and hydrology are relevant control factors determining the timing and amount of nutrient losses from land to downstream aquatic systems, in particular of phosphorus (P) from agricultural lands. The main objective of the study was to evaluate

Dissolved organic matter (DOM) is an important factor in aquatic ecosystems, which is involved in a large variety of biogeochemical and ecological processes, and recent literature suggests that it could be strongly affected by agriculture in differen

The pre-synchronous condition of generators operating at normal speed, with voltage on manual control, while connected to open circuited step up transformers, can last several minutes. This is particularly true if plant problems delay the synchroniza

This paper describes a test procedure for derivation of synchronous machine parameters. The tests can be conducted with ease and without hazard on generators in utility systems. Unlike textbook methods involving short circuit and slip tests which are
